- GPRS subscribers to reach 6 million by 2002 if operators implement effective roaming arrangements in next six months

- GPRS roaming exchanges (GRXs) favoured by operators due to QoS, security and control, but uncertainty remains and trials continue

- GRX providers will extend their role beyond data transport, although they must seek co-operation from mobile operators.

CAMBRIDGE, UK, December 12, 2001 - Enabling international roaming for general packet radio service (GPRS) is a prerequisite for the take-off of this new mobile data service, according to GPRS Roaming: technical options and strategic implications, a new report published today by Analysys, the global advisor on telecoms and new media (

The report forecasts that GPRS subscriber numbers in Western Europe will approach 6 million by the end of 2002 (Chart - GPRS subscribers in Western Europe by market segment - is available to journalists on request). However, this will only be achieved if roaming to GPRS users' main travelling destinations becomes possible within the next six months.

"While very little GPRS data revenue will be derived directly from roaming," says lead author Katrina Bond, "it is critical for attracting early adopters, particularly business people whose main reason for wanting GPRS services is to access email and corporate applications when travelling."

However, according to Analysys, roaming models used for current mobile voice services over GSM networks are inadequate for coping with the increased complexity of billing and providing a consistent method of access for the broad range of services that are being introduced over GPRS networks.

Mobile operators are therefore in the process of evaluating two alternative models for connecting roaming customers to GPRS services: via the Internet, or using a GPRS roaming exchange (GRX) as a hub for routeing GPRS data along private IP connections.

Some operators have already stated their intention to use the GRX model, including Europolitan, SONOFON and Telia Mobile in the Nordic region, Orange in the UK, Hutchison Telecom in Hong Kong, and VoiceStream in the USA. However, other operators, such as Mobilkom Austria and SingTel, are testing both models and are yet to decide which they will adopt.

Nevertheless, the report argues that the GRX model will dominate for GPRS roaming because of the additional quality of service (QoS) and security it provides, and, importantly, because of the level of control it affords operators over the services their customers can access. However, the GRX model also favours another group of companies: those IP backbone providers and roaming brokers that are establishing themselves as GRX providers.

Not only will GRX providers have an important role in carrying GPRS roaming traffic, but there is also the potential for some GRX providers to provide hosting facilities and act as a marketing channel for mobile portals and ASPs. GRX providers Telia International Carrier and TSI have already indicated an intention to do this.

In addition, some GRX providers could extend their role further into content management, but in doing so should seek co-operation from their mobile operator customers. Cable & Wireless, for example, is well placed following its acquisition of content delivery network Digital Island in June 2001, and its confirmation in December 2001 that it would purchase the assets of datacentre operator Exodus Communications.

Written by Katrina Bond, David Wilkins and Michael Kende, the report evaluates the ISP and GRX models of GPRS roaming, and assesses the current progress in implementing the latter model by mobile operators and GRX providers. It also analyses the potential role for GRX providers in complementary services, and the implications for the marketing channels pursued by mobile portals and ASPs. Recommendations are provided for mobile operators, GRX providers, and content and application providers.
