GSM and GPRS complete the packet data function by adding a series of functional entities to the original GSM network. The new functional entities form the GSM and GPRS networks as independent networks. The entity bypasses the CSM data to complete the GPRS service, and the original GSM network completes the voice function, minimizing changes to the CSM network.

The GPRS network and the original GSM network jointly complete the mobile management function of the mobile station through a series of interface protocols. GPRS has added some new functional entities: service GPRS support node SCSN, gateway GPRS support node GCSN, point-to-multipoint data service center, etc., as well as a series of enhancements to the software functions of the original functional entities. GPRS draws on and uses data on a large scale. Communication technologies and products, including frame relay, routers, Internet servers, firewalls, etc.

GPRS was first proposed in 1993, and the first phase of the protocol was introduced in 1997. So far, the GPRS protocol is still being continuously updated. In early 2000, SMG30 was launched, which provides anonymous access. The entry function is no longer reflected in the new protocol. In addition to the newly introduced protocols, the GPRS protocol has also made many modifications to some of the original protocols.
