The Short Message Service (SMS) is the ability to send and receive text messages to and from mobile telephones. The text can comprise of words or numbers or an alphanumeric combination. SMS was created as part of the GSM Phase 1 standard. The first short message is believed to have been sent in December 1992 from a Personal Computer (PC) to a mobile phone on the Vodafone GSM network in the UK. Each short message is up to 160 characters is length when Latin alphabets are used, and 70 characters in length when non-Latin alphabets such as Arabic and Chinese are used.
There is no doubting the success of the Short Message Service- the market in Europe alone has reached over one billion messages despite little proactive marketing by network operators and phone manufacturers. Key market drivers over the next two years such as the Wireless Application Protocol (WAP) will continue this growth path.
The SMS market in the European Union
reached one billion short messages per month in April 1999.
Specific examples for certain leading mobile operators are:
So how have these network operators developed their messaging volumes to such a high degree? How can you develop your own messaging market? What the factors that are driving the continuing growth in the SMS market and to what degree?
The network operator needs to purchase its first generation SMS Center as part of the network commissioning plan. The initial SMS Center may be simply a voice mail platform module or alternatively a standalone SMS Center. It is not possible to make the Short Message Service available without an SMS Center since all short messages pass through the SMS Center.
The network operator sees SMS as a "tick box option"- something to say that it does have on its network. Often SMS Mobile Terminate Services are offered along with voice mail notifications, which account for the vast majority of SMS traffic on the network- typically over three-quarters.
The network operator launches SMS Mobile Originate to give customer true two-way SMS capability. Customers experiment with the service and work out new uses for it. Addition of SMS Mobile Originate typically leads to 25% increase in overall SMS volumes being handled.
Additional of a wireless Internet/ mobile email service often follows, typically with the customer's mobile number becoming part of the email address they are allocated as part of the service. Emails sent to that address are forwarded as a short message to their wireless phone. Such a service tends to be popular with customers, especially in markets where Internet penetration is low and people don't already have an email address. This typically leads to 20% increase in overall SMS volumes being handled.
Addition of information services. These services typically start with mainstream content such as news, travel, weather and sports and over time, new information providers are sourced that offer lifestyle services such as horoscopes and jokes. Because there is typically a lot of work involved in sourcing and setting up content, these services tend to build up slowly, typically accounting for about a 10% increase in SMS volumes being handled.
The network operator starts to see independent companies experimenting with SMS-based applications and offering these on a regional or company-specific basis. To encourage these developments and assist in their widespread deployment, the network operator hires a person whose sole responsibility is to manage relations with these business partners and help them to get any technical or commercial support they need. The aim is to try to get the businesspartners to deploy their applications using their network's SMS services rather than those of their competitors. Because vertical market applications can account for high messaging volumes, the introduction of a business partners program can soon lead to a further 20% increase in overall SMS message volumes being handled by the network.
The network operator has seen gradual but significant increases in SMS traffic volumes as these initiatives have been taken and awareness of SMS builds.
They then often find that their SMS Center capacity is starting to be challenged and need to expand the existing platform or purchase an industrial strength SMS Center from another supplier. This then removes any constraints in handling messages, and may lead to corporate customer complaints about service reliability at peak times falling, typically leading to a 10% increase in overall SMS message volumes.
The additional of interworking between
network operators who are competing in the same geographical market gives
customers to both networks the opportunity to use SMS in the same way as
they do voice. Just as they can make a voice call to each other's phones,
so too can they send short messages to each other.
By this time, the total use of SMS on the network has reached "Critical Mass". There are sufficient regular users and awareness of and momentum behind the services. SMS has become an integral and important part of many customer's everyday business and personal lives. Facilitating international SMS roaming is also important, particularly in land-locked countries where border crossing is frequent.
The next quantum leap in SMS traffic volumes is caused by the introduction of SMS for prepayment customers. These customers pay for their cellular airtime as they go rather than having contracts. Enabling the prepay customers to send short messages causes large traffic uplifts because the typical young person who is the main user of prepaid services is also ready, willing and able to manipulate the phone keypad and originate short messages. When customers are cost conscious, they tend to use SMS to let their friends know about changes in meeting arrangements and so on, calculating that this is less expensive than making a voice call to communicate the same information. An increase in SMS traffic of 100% (sometimes more) is not unusual when SMS for prepay is introduced.
For example, as we saw at the start of this guide, whilst Vodafone in the UK had more postpaid customers than prepay (three million postpaid, two million prepaid), the prepay customers sent more than twice as many short messages as the postpaid users.
Because simple person to person messaging is such an important component of total SMS traffic volumes, anything that simplifies message generation is an important enabler of SMS. Predictive text input algorithms such as T9 from Tegic that anticipate which word the user is trying to generate significantly reduce the number of key strokes that need to be made to input a message. Widespread incorporation of such algorithms into the installed base of mobile phones will typically lead to an average uplift in SMS traffic of 25% per enabled user. These predictive text algorithms support multiple languages.
The introduction of standardized protocols such as SIM Application Toolkit and the Wireless Application Protocol (WAP) contributes to an increase in messaging usage by providing a standard service development and deployment environment for application developers and business partners. These protocols also make it easier for users to reply to and otherwise access messaging services through the provision of custom menus on the phone. As such, whilst these protocols are only a means to an end and not new messaging destinations or services in their own right, they are likely to lead to a 10-15% uplift in total SMS volumes.
The introduction of more friendly and easy to use terminals contributes to increases in messaging usage by providing simpler access to messaging services. Terminals such as smart phones make it easier for users to originate, reply to and otherwise access messaging services through the provision of a QWERTY keyboard rather than the limited keypad on standard mobile phones. As such, whilst these terminals are only a means to an end and not new messaging destinations or services in their own right, they are likely to lead to a 10-15% uplift in total SMS volumes.
As such, there are various steps that mobile carriers can and should take to spur the development of SMS usage. Each of these steps is complementary and useful in making SMS a success. It is the combined effect from these steps that has led to the significant and almost exponential growth in the usage of SMS by many developed network operators in the late 1990s.
The vast majority of SMS usage is accounted for by consumer applications. It is not uncommon to find 90% of a network operator's total SMS traffic being accounted for by the applications described in this next section. The main consumer applications based on SMS are:
Mobile phone users to communicate with each other routinely use the Short Message Service. Typically, such person to person messaging is used to say hello or prompt someone for something or arrange a meeting or tell someone something. Such messages are usually originated from the mobile phone keypad.
When the information to be communicated is
short or it would take too long to have a full conversation or someone is
traveling overseas or not available to take a voice call, SMS is an ideal
messaging medium. For example, network operators typically charge the same
to send a short message to someone in the same room as they do to someone
traveling overseas with their mobile phone.
Once users have familiarized themselves with reading and sending short messages, they often find that SMS is a useful way of exchanging information and keeping in touch with friends. This is particularly so when the recipient is also able to reply to messages for two-way communication. If the recipient of the short message is unable to read or reply to it, then clearly the effectiveness of using SMS as the communications media is much lower. This is one of the reasons why simple person to person messaging is popular with many young people, a group that is generally more willing to learn how to use new technologies such as SMS. As such, simple person to person messaging generates a high volume of short messages.
The most common use of SMS is for notifying
mobile phone users that they have new voice or fax mail messages waiting.
This is therefore the starting point for most mobile network operators and
the first (but hopefully not the last) time that mobile phone users use
SMS. Whenever a new message is dispatched into the mailbox, an alert by
SMS informs the user of this fact.
Unified messaging is an emerging value-added network service that is particularly compelling because it elevates communication above the technology used to communicate- the message takes precedence over the media. Currently, it is difficult to manage all the different kinds of messages that people get- they have to dial in and pick up emails, pick up their faxes from the fax machine, call in and listen to voice mail and so on.
Unified messaging involves providing a single interface for people to access the various different kinds of messaging they use. Be the messages fax, voice mail, short messages, email or so on, they can be conveniently accessed from a single point in the most actionable form.
The user typically receives a short message notifying them that they have a new message in their unified messaging box. The short message often also includes an indication of the type of new message that has been deposited, such as fax, email or voice mail.
Unified messaging is a convenient application that is likely to become mainstream in the future. It should therefore be a significant generator of short messages as more services are launched.
Upon receiving a new email in their mailbox, most Internet email users do not get notified of this fact. They have to dial in speculatively and periodically to check their mailbox contents. However, by linking Internet email with SMS, users can be notified whenever a new email is received.
The Internet email alert is provided in the form of a short message that typically details the sender of the email, the subject field and first few words of the email message. Most of the mobile Internet email solutions incorporate filtering, such that users are only notified of certain messages with user-defined keywords in the subject field or from certain senders. Users could find it expensive or inconvenient to be alerted about every email they receive (including unsolicited "spam" emails), which would reduce the value of the service.
Because of the high and increasing usage of Internet email to communicate globally, and the benefit from using SMS to notify mobile users about important new email messages, this is likely to be a fast growing and popular application for SMS.
Another emerging SMS-based application is downloading ringtones. Ringtones are the tunes that the phone plays when someone calls it. With the same phone often sold with the same default tune, it is important for phone users to be able to change their ringtone to distinguish it from others. Phones often come with a range of different ringtones built into the phone's memory that the users can choose from. However, it has become popular to download new ringtones from an Internet site to the phone- these phones tend to be popular television or film theme tunes. It is important that network operators consider copyright issues when offering ringtone services, since such commercial tunes much be licensed before they can legally be distributed (the people behind "The Saint" theme tune must be getting reach!). Ringtone composers are also popular because they allow mobile phone users to compose their own unique ringtones and download them to their phones.
Much of the usage is spurred by word of mouth- people hear someone else's phone ringing and ask where they got that particular ringtone.
As mobile phone penetration increases, and everyone has a mobile phone, unique ringtones to help determine just whose phone is ringing will become increasingly popular. Expect to see this application grow in availability and popularity over time.
An emerging application for the Short Message Service is chat. In the same way as Internet chat groups have proven a very popular application of the Internet, groups of likeminded people- so called communities of interest- have begun to use SMS as a means to chat and communicate and discuss.
Chat can be distinguished from general information services because the source of the information is a person with chat whereas it tends to be from an Internet site for information services. The "information intensity"- the amount of information transferred per message tends to be lower with chat, where people are more likely to state opinions than factual data.
SMS-based chat services are an emerging application area. It remains to be seen how willing the participants in the chat groups are to pay for EVERY message sent to the chat channel. It is likely that commercial chat services will let participants select which messages they receive on their mobiles according to who the message sender is.
Because SMS chat applications are high volume applications whereby one message submission leads to multiple message deliveries, expect this application to be a significant generator of short messages in the future.
The Short Message Service can be used to deliver a wide range of information to mobile phone users from share prices, sports scores, weather, flight information, news headlines, lottery results, jokes to horoscopes. Essentially, any information that fits into a short message can be delivered by SMS.
Information services can therefore be configured as push-based and from a public or private source or pull-based and from a public or private source. An information service for an affinity program may combine public information such as share prices with private information from bank databases.
Successful information services should be simple to use, timely, personalized and localized.
Corporate applications that use the Short Message Service are currently few and far between. Most of the SMS messaging volumes are generated by consumer applications. The reasons are the older age of corporate mobile phone users and their lower price sensitivity, particularly since mobile phones bills are usually paid by the company. Corporate users are less willing to learn how to and make the effort to send a short message- they tend to use voice as their primary communications method. The main corporate applications based on SMS are:
The Short Message Service can be used to extend the use of corporate email systems beyond an employee's desk and office PC. With 40% of employees typically away from their desks at any one time, it is important for them to keep in touch with the office at all times. Corporate email systems run on Local Area computer Networks (LAN) and include Microsoft Mail, Outlook, Outlook Express, Microsoft Exchange, Lotus Notes and Lotus cc:Mail.
Corporate email notifications are similar to Internet email notifications. Users are given information such as the sender and subject of the email. Any emails of a business or personal nature that are sent to the corporate email address can be sent out over the wireless network.
Because unlike Internet email notifications, corporate email services tend to use the existing corporate infrastructure and email addresses, this kind of email application tends to generate significant average quantities of short messages per user. Very few corporations have so far extended their office email systems out to the wireless environment, leaving a large opportunity for the deployment of such services.
Some mobile network operators view the development of the Short Message Service as low down in their overall priorities- because few users select the mobile network solely or primarily on the basis of SMS. However, affinity programs- which are also known as lifestyle packages- are a large opportunity for mobile network operators with the potential to secure large numbers of new customers, in which SMS is an integral part of the offering.
Affinity programs are the result of collaboration between mobile carriers and other companies in different industries with large customer groups. Affinity partners include television companies, sports clubs, supermarkets and other retailers, airlines and banks. SMS can be used to provide customers will all kinds of reminders and information such as frequent flyer miles status, overdue videotape rentals, appointment reminders and prescription drug pick-up notifications.
All parties to affinity programs can potentially benefit from the partnership- mobile network operators gain access to a largely new set of potential customers and affinity partners get to offer their customers new convenient services to their customers- offering differentiation possibilities against their competitors.
For affinity programs, the mobile phone may be branded with the affinity partner's logo and may have custom and personalized packaging. The route to market- i.e. the sales channel for the affinity product- is likely to be different from that of standard mobile phone purchases. Typically, the customized phones are marketed and distributed using direct mail- customers receive information about the affinity program through an insert into their statements or bills and they can then sign up and receive the package containing the mobile phone by post. A single bill, lower rates and easy access to the services are often features of the affinity package.
Let us take a closer look at a specific kind of affinity program- mobile banking.
The successful implementation of mobile banking programs incorporates several different elements discussed in this guide, such as Information services and SIM Application Toolkit.
Affinity programs and related lifestyle packages are a fast growing area of mobile communications, because as competition between network operators increases, differentiation and customization for specific user groups will be necessary to extend mobile phone penetration and usage. As such, they are likely to be a significant generator of short messages.
Electronic commerce applications involve using a mobile phone for financial transaction purposes- this usually means making a payment for goods or transferring funds electronically. Transferring money between accounts and paying for purchases are electronic commerce applications.
The convenience of paying for purchases using SMS must be weighed against the related issues of security, integration with the retail and banking hardware and systems, and money transfer issues. However, this area of electronic commerce applications is expected to contribute to growing SMS traffic in the
By providing mobile phone customers will information about their account, the Short Message Service can help to avoid the need for expensive person to person voice calls to customer service centers. In the customer service environment, SMS can help to deliver account status information, new service configuration and so on, in particular when standard SMS is combined with a protocol such as SIM Application Toolkit or Wireless Application Protocol. Some network operators find significant financial justification for deploying a value-added services platform on the basis of what they save in customer service costs alone.
This application integrates satellite positioning systems that tell people where they are with SMS which lets people tell others where they are. The Global Positioning System (GPS) is a free-to-use global network of 24 satellites run by the US Department of Defense. Anyone with a Global Positioning System (GPS) receiver can receive their satellite position and thereby find out where they are.
Many commercial GPS receivers also incorporate support for the Russian equivalent of the Global Positioning System.
The Short Message Service is ideal for sending Global Positioning System (GPS) position information such as longitude, latitude, bearing and altitude. GPS information is typically about 60 characters in length, leaving room for other information such as the vehicle registration details, average speed from the tachometer and so on to be transmitted as part of the same short message.
Because the position updates are automatically generated, mobile network operators find that vehicle positioning applications are amongst the leading generators of short messages.
160 characters is sufficient for communicating most delivery addresses such as those needed for a sales, service or some other job dispatch application such as mobile pizza delivery and courier package delivery.
The Short Message Service is used to assign and communicate new jobs from office-based staff to mobile field staff. Customers typically telephone a call center whose staff take the call and categorize it. Those calls requiring a visit by field sales or service representative can then be escalated to those mobile workers using SMS. Job dispatch applications can optionally be combined with vehicle positioning applications- such that the nearest available suitable personnel can be deployed to serve a customer.
SMS can be used not only to send the job out, but also as a means for the service engineer or sales person can keep the office informed of progress towards meeting the customer’s requirement. The remote worker can send in a short status message such as "Job 1234 complete, on my way to 1235".
Because of the need to communicate with mobile workers and effectively and cost-effectively serve customers, such job dispatch applications are likely to be steady generators of short messages.
SMS can also be used in a retail environment for credit card authorization. It is particularly convenient to use mobile technology when making sales from, for example, carts in the middle of isles at shopping malls, at flee markets or at sports stadiums, where it would be inconvenient to trail a fixed telephone wire. A mobile phone is connected to a Point of Sale terminal such as a credit card swipe and keypad. The credit card number is sent to a bank for authorization. The authorization code is then returned as a short message to the Point of Sale terminal.
Over the air capability gives mobile network operators, application developers and corporate sales managers some remote control of mobile phones for service and subscription activation, personalization and programming.
Over the air facilitates a number of end user applications such as remote service activation and update book updates.
The Short Message Service can be used to manage machines in a remote monitoring environment. This application provides people with valuable information from a remote location when an important event occurs that they need to know about. The information is automatically delivered electronically without having to constantly employ physical resources locally on the off chance that such an event occurs. Examples of remote monitoring applications include remote meter reading, sending computer system fault information to mobile phones and notifying companies about empty vending machines.
Now that we have looked at the major applications that SMS facilitates, lets take a closer look at some of the factors that facilitate the achievement of the messaging milestones.
NATIONAL SMS INTERWORKING
Most network operators around the world recognize the need to allow customers to send short messages to people on network operators competing in the same country as them. Just as you can call using voice, so too should you be able to communicate using the Short Message Service.
To release national SMS interconnects, there are some issues. From a commercial perspective, network operators competing in the same country often charge different prices for the Short Message Service and offer different services.
In such cases, knowledgeable users could benefit from accessing less expensive or more sophisticated Short Message Services by changing SMS Center addresses or sending their messages in a different way. A price has to be agreed for such inter-network national messaging to discourage or prevent such behavior.
Technically speaking, network operators are reluctant to allow their competitors access to their signaling channels, over which short messages are transmitted.
This is because these channels also handle voice call set up and other mission critical tasks. However, firewalls have resolved many of these technical issues.
For example, about half the countries in Europe had inter-network national roaming by mid-1999 (including Scandinavia, UK, Netherlands) whilst half did not (including Germany, Portugal and France).
Generally with the GSM Short Message Service, no specific international SMS roaming agreement is needed to use SMS overseas. Instead, international SMS roaming automatically arises whenever the following conditions are met:
Nearly all GSM mobile telephones are able to receive short messages (known as SMS MT: Mobile Terminate). The only known exceptions that CANNOT receive short messages are some of the very first GSM mobile phones released in the early 1990s such as the Motorola 3200, the AEG Telcard 901 and the Alcatel HB100.
All major and minor phone manufacturers without exception now have at least one mobile phone available that can send short messages (known as SMS MO: Mobile Originate). Furthermore, most phone manufacturers are not now supplying ANY mobile phones in their range of models that do NOT support SMS send. Even budget phones can send messages. As such, the percentage of phones that are able to send short messages is increasing over time. At the beginning of 1999, approximately 75% of the installed worldwide base of GSM mobile phones were capable of SENDING a short message.
My optimal mobile device for using the Short Message Service would have the following features:
1. Predictive text input algorithms such
as T9 from Tegic
SIM Application Toolkit has been agreed and incorporated within the Global System for Mobiles (GSM) standard. "SIM" denotes the smart card inserted into GSM mobile phones that contains information about the user.
SIM Application Toolkit allows the flexibility to update the SIM to alter the services and download new services over the air. For example, network operators can remotely provision the user's wireless terminal by sending codes embedded in short messages from the server. Within the SIM Application Toolkit specification, the Short Message Service is a key mechanism for personalizing the SIM in each user's GSM phone.
SIM Application Toolkit is designed as a client-server application. On the server side, SimCard platform specialists such as Orga, Gemplus and AU-System have introduced servers based on this standard. On the client side, phone manufacturers such as Siemens, Motorola, Bosch, Sagem and Alcatel have launched phones that have support SIM Application Toolkit. Significantly, two of the three largest mobile phone vendors, Ericsson and Nokia, have not launched or announced SIM Application Toolkit compliant phones.
The biggest advantages of SIM Application Toolkit are that it has been:
WAP is an attempt to define the standard for how content from the Internet is filtered for mobile communications. WAP was developed to be the way of making readily available content from the Internet easily available to mobile terminals.
One of the reasons why the mobile industry has got so excited about WAP is because it combines two of the fastest growing industries: wireless and the Internet.
The Wireless Application Protocol is envisaged as a comprehensive and scaleable protocol designed for use with:
The Wireless Application Protocol incorporates a relatively simple micro-browser into the mobile phone. WAP is aimed at turning a mass-market mobile phone into a "network-based smartphone". As a representative from the board of the WAP Forum commented "The philosophy behind Wireless Application Protocol's approach is to utilize as few resources as possible on the handheld device and compensate for the constraints of the device by enriching the functionality of the network".
The initial Wireless Application Protocol partner companies- Nokia, Ericsson, Motorola and Phone.com (formerly Unwired Planet)- formed a company called WAP Forum Limited to administer the global Wireless Application Protocol specification process and get new companies involved in developing the protocol. By mid 1999, the WAP Forum had about 100 members comprising major phone manufacturers, network operators, SMS Center suppliers and SMS software suppliers. See www.wapforum.orgfor a current list.
For any WAP service to be launched on a mobile network (or SIM Application Toolkit), there needs to be an installed base of clients and servers. In mid-1999, WAP had many servers but no clients!
Nokia's policy is to incorporate WAP into high-end phones such as the 7110 but not consumer-oriented phones such as the 3120. As such, the consumer market that is today's heavy user of SMS will not have access to the Wireless Application Protocol (WAP) until it has trickled down through the product range and become a standard feature. This decision will significantly delay WAP's market penetration and acceptance. Given that neither the 7110 nor the 3120 will be available in volume until the end of 1999, mass market Wireless Application Protocol (WAP) support will not arise until 2001 at the earliest.
Other phone vendors such as Alcatel have announced that they are introducing support for the Wireless Application Protocol across their entire product range.
However, since WAP requires a larger screen size and more memory to handle the WAP stack, it costs more to produce a WAP handset and will therefore mean more expensive mobile phone prices.
On the server side, there are about a dozen suppliers of WAP servers including CMG, Nokia, Ericsson, Phone.com (formerly Unwired Planet), SST, Dr. Materna, APiON, MD-Co, Akumiitti and Oracle. SMS services platform suppliers such as Sendit and Tecnomen have NOT developed their own WAP Gateway. These WAP server suppliers are all trying to sign up mobile network operators who are looking to trial WAP services and gain some market feedback. WAP trials will commence in the summer of 1999.
It is a valid question to ask whether the Short Message Service (SMS) has a prosperous future ahead of it given that GSM is evolving to encompass high-speed packet data services such as GSM Packet Radio Service (GPRS) (See www.mobileGPRS.com).
GSM SMS has several unique features that can be summarized as message storage if the recipient is not available, confirmation of short message delivery to the sender and simultaneous transmission with GSM voice, data and fax services. Importantly, these features will NOT be incorporated into other planned GSM services such as GPRS. However, SMS does have some disadvantages-primarily the limited message length of 160 characters.
SMS as we know it will be used through to the year 2005 at least, since the mobile phones, infrastructure, specifications, market development and awareness are in place today. Over time, as users connect to networks that offer more advanced data services and buy mobile terminals that support them, they will find it more convenient to receive all their CHOSEN emails rather than only a notification by SMS. They will continue to use SMS for some applications- the underlying bearer will be mixed and matched according to the application and its importance to the user. SMS could be used automatically when roaming for example due to the advantages of store and forward when in a different time zone. Non-urgent emails could be sent by SMS for users to decide whether to forward the entire message. Urgent emails get sent immediately using packet data. By supporting multiple standards and bearer services, the Wireless Application Protocol anticipates this multiple service world. Essentially, in 3GSM, SMS will not be a standalone service but part of multimedia messaging. Different applications will use different bearer services- bearers will be mixed and matched depending on characteristics of application and mobile environment.
Because SMS is a store and forward service, every single short message of any type passes through an SMS Center. As such, the selection of an SMS Center vendor is absolutely critical to success of the mobile network carrier's SMS-based services. The reliability of SMS services varies considerably between different mobile networks because they deploy different SMS Centers. In other words, not all SMS is the same. Choose badly and mobile network operators limit the possibilities of using SMS for time and mission critical applications such as for the emergency services, stolen vehicle recovery and so on. The deployment of further services is also severely hindered if there is insufficient SMS Center capacity and expandability.
SMS Center selection criteria include platform scalability, availability and reliability, connectivity and pricing. The main SMS Center vendors are CMG Telecommunications, Comverse Network Systems, Logica Aldiscon, ADC NewNet, Nokia, Ericsson, Motorola and Sema Group.
These SMS Centers are compared according to their feature sets below:
Denotes SMS Center connectivity. All the SMS Center vendors support TCP/IP access. Ericsson connectivity is limited to networks with Ericsson mobile infrastructure. Theoretical connectivity does not necessarily mean that all the deployed SMS Centers by that vendor support that form of connectivity- for example, few Sema Group SMS Centers in Europe support anything other than X.25 connectivity.
Denotes the cost of deploying the platform.
ADC NewNet is the least expensive SMS Center. A network operator receiving
quotations for a comparable volume and capacity found that CMG was the
most expensive, followed by Sema, Logica Aldiscon and Nokia, who were
priced comparably. CMG was around 50% more expensive in that case. The
support cost was comparable among all the SMS Center vendors.
Denotes the extent to which SMS Center has been widely deployed and the size of the customer base using that SMS Center. Logica Aldiscon has the highest number of SMS Center deployments globally, whilst Nokia, Motorola, Sema and CMG each have 35 to 45 platform installations in total. ADC NewNet, a relatively recent entrant into the SMS Center market, has deployed about a dozen SMS Centers. CMG supplies many large European network operators with high SMS traffic volumes.
Denotes the extent to which the SMS Center is future-proof, and therefore incorporates or is designed to incorporate new mobile data protocols, services and standards. Nokia, CMG and Sema have all taken a proactive stance towards future SMS-based standards such as the Wireless Application Protocol (WAP).
As a founder member of WAP Forum, Nokia is particularly committed to developing future-proof products and services. Ericsson was also a founding partner in the WAP Forum, but has not publicly announced support for WAP by its MXE SMS Center. Logica Aldiscon has announced support for GSM Phase 2+ features and joined the WAP Forum. ADC NewNet has not joined the WAP Forum or made its position on supporting future standards clear.
Denotes the extent to which the deployments of the SMS Center are dispersed globally. Widespread global deployment means that the SMS Center is likely to have been interfaced with almost all the possible different configurations of mobile network architecture, from voice mail suppliers to SS7 signaling vendors, Home Location Registers (HLRs) and Mobile Switching Centres (MSCs).
Logica Aldiscon has deployed its SMS Center globally on every continent- its Telepath platform also pioneered the implementation of SMS in markets such as Japan. CMG has been very successful in implementing SMS Centers for mobile network operators running analog NMT networks- in particular in Eastern Europe.
But CMG has few deployments outside of continental and Eastern Europe, and those few it currently has were supplied through Ericsson. The Sema SMS Center has been widely deployed on every continent. ADC NewNet have some installations in major markets such as India and China, Europe and the US.
Ericsson MXE customers are globally dispersed- but do tend to be concentrated in North and South America.
Denotes the reliability of the SMS Center. ADC NewNet, Sema and CMG have highly reliable SMS Centers that once deployed, are able to reliably handle significant volumes of short messages. Nokia’s SMS Center has adequate levels of reliability for standard short messaging purposes. The SC4 upgrade to the Nokia SMS Center significantly enhanced its reliability. Logica Aldiscon and Ericsson customers have complained about inconsistencies in the reliability of their SMS Centers- Logica Aldiscon’s System Release 2600 should assist in improving its reliability.
Both Sema and CMG use the high speed Compaq Alpha Server, both Ericsson and ADC NewNet use Sun Sparc stations and both Nokia and Logica Aldiscon have built their SMS Center on a Hewlett-Packard 9000 server. The Sun approach has the advantage of being industry-standard hardware that is readily available at a low entry price. In mid 1988, Hewlett-Packard launched its "Service Guard" concept that improves platform availability and has been adopted by both Nokia and Logica Aldiscon.
For a relatively simple messaging service, there certainly are a lot of elements that need to be taken into account when developing and deploying SMS! However operators who take the time and trouble to invest in SMS will find appreciative customers and appreciating revenues. As such, please say "Yes to SMS"!
