Nokia announces world's first GPRS roaming between M1 Singapore and Cable and Wireless HKT Mobile Services, Hong Kong
March 20, 2000
This trial leads the way towards global mobile packet data services. Operators will benefit from GPRS roaming by being able to provide their customers the same data services regardless of the network that they are visiting. In this instance, the two networks were connected with a secure virtual private network across the Internet using GPRS Border Gateway elements.
The Nokia GPRS system comprises of the Nokia SGSN (Serving GPRS Support Node), Nokia GGSN (Gateway GPRS Support Node), the Nokia CG (Charging Gateway), Nokia Boarder Gateway and necessary IP backbone elements.
"This important step demonstrates that we can support cross network roaming traffic in the SGSN and GGSN interface. GPRS roaming will enable our customers to continue using their regular GPRS access points and services while roaming in foreign destinations," says Patrick Scodeller, Director, Engineering, M1.
Adam Wong, Director, Mobile Networks, Cable & Wireless HKT Mobile Services says; "Roaming is an essential part of GPRS services. Many GSM users have learned to expect continuity of their services, while abroad. This successful roaming verification gives us the confidence that GPRS services will meet customer's expectations."
"We are proud to announce this successful roaming with two frontrunner operators in Asia; a world first for us. Not only was inter-operator roaming demonstrated here, but also the interoperability of the roaming interface between the SGSN and the GGSN," says Petri Pöyhönen, Head of GPRS Business Program, Nokia Networks.
This announcement further strengthens Nokia's leadership position in GPRS. GPRS is an essential step for operators in their evolution towards 3rd Generation services as it provides the packet core technology for mobile Internet services.

Notes to Editors:
GPRS offers instant packet-switched connections to data networks via GSM technology. In addition to allowing faster and easier Internet access this continuous connectivity enables a variety of new applications such as multimedia messaging, wireless corporate intranet, remote control and maintenance of appliances and any number of monitoring or surveillance applications.
GPRS roaming requires that SGSN and GGSN network elements connect across an international IP link. SGSN in the visited destination provides the GPRS support for the radio access, GGSN in the home network supports access to the Internet and Intranet destinations in the home country.
GPRS Access Point corresponds to the dialled digits in voice telephony, specifying the destination of the data connection. GPRS Access Points specify destinations such as Internet Service Providers (ISP), a WAP Gateway for mobile aware content services, or corporate Intranet access point for secure connectivity to an enterprise network. GPRS roaming enables all these services to remain available while visiting another GPRS network. GPRS roaming will also enable the home network to maintain more control over charging of roaming traffic, because all traffic will be routed through the home network GGSN, which collects charging information.
