GPRS (general packet radio service) roaming requires subscribers to connect to an outside GPRS network.
GPRS, or general packet radio service, is a mobile data service offered on 2G (second-generation) and 3G (third-generation) cellular networks. GPRS services offers a fast data-transfer rate and a certain QoS (quality of service) to subscribers. GPRS roaming can create complications both for subscribers and service providers.
Definition
Roaming refers to the extension of wireless communications service to an area outside the home location in which the service is offered. GPRS roaming requires operators to interconnect wireless networks, due to the existence of different GPRS services provided on different networks.
GPRS Roaming Exchange
The GRX, or GPRS Roaming Exchange, is used as a hub to connect GPRS services to roaming subscribers. The GRX was designed to eliminate the need for operators to create a dedicated link to operators of other GPRS services in other areas of the world. This dedicated link also required a contract between operators.
Features
In the GRX, operators have access to a network of links and routers that connect to other GPRS networks. This enables operators to connect roaming partners quickly. This also lessens the possibility of a roaming subscriber being unable to connect, or gain a signal to a outside GPRS network, due to the lack of a contract agreement between the providers.
