Editing GPRS core network (section)

{{short description|Central part of the general packet radio service}}
The '''GPRS core network''' is the central part of the [[general packet radio service]] (GPRS) which allows [[2G]], [[3G]] and [[WCDMA]] [[mobile telephony|mobile networks]] to transmit [[Internet Protocol]] (IP) packets to external networks such as the [[Internet]].  The GPRS system is an integrated part of the [[GSM]] [[network switching subsystem]].

The network provides [[mobility management]], [[session management]] and [[Transport layer|transport]] for IP packet services in GSM and WCDMA networks.  The core network also provides support for other functions such as [[Telecommunications billing|billing]] and [[lawful interception]].  It was also proposed, at one stage, to support packet radio services in the US [[Digital AMPS|D-AMPS TDMA]] system, however, in practice, all of these networks have been converted to GSM so this option has become irrelevant.

PRS module is an open standards driven system. The standardization body is the [[3GPP]].
