Abstract [en]

The purpose of this report is to show that the mobile Internet to some extent can be made to happen today by integrating existing GSM and Internet infrastructures while adding a little intelligence. In this report we will study some services that can be created by using GSM’s short messages as bearer, how these services should be devised, and how to get revenue from them. GSM users can send short text messages to other subscribers, not only within the home network, but to most GSM users in the world1. By introducing gateways to the Internet, we will have a low bandwidth subset of the mobile Internet. With the use of the short message service we will also have to deal with several challenges, all addressed in this report:

  • Meagre bandwidth and limited user friendliness in the terminal

  • Pricing of services that span the opposites in existing tariffs, i.e. high-cost mobile telephony and flat rate Internet.

  • The lion share of the traffic comes from the Internet and cannot be billed to the sender. Will the subscriber accept paying?

Since SMS is asynchronous much like email, we have studied bridging email to and from SMS, and email notification over SMS. The former is now a commercial service, “IQ E-post”, and the latter is a fully operational demo system.

The work was performed at Tele2 during 1996 and 1997 with the active support of Comviq GSM, Sweden’s biggest ISP and independent GSM network respectively. Since then, a user-friendlier microbrowser framework, the Wireless Application Protocol (WAP), has been introduced [WAP]; and true wireless packet-data for GSM will be commercial during 2000. This will make the merger of high-cost wireless and flat rate Internet even more of a challenge than with plain SMS.

1Subject to roaming agreements with other operators and special arrangements such as bridging messages between competing networks in the same country or region.
