Abstract
Description
technical field
[0001] The invention relates to the technical field of network communication, in particular to a mobile communication network service access system and method. Background technique
[0002] The mobile communication network generally includes two parts, the wireless access network and the core network. The wireless access network accesses the core network through the GPRS service support node SGSN, and then the SGSN continues to connect with the GPRS gateway support node GGSN through the GTP protocol, and the mobile terminal is realized through the GGSN. Access to external data networks, such as communication systems such as GPRS, WCDMA and CDMA 2000.
[0003] Take GPRS as an example, such as figure 1 As shown, the serving support node SGSN and the gateway support node GGSN are the key equipment of the core network of the GPRS / 3G communication system, and the packet control unit PCU / radio network controller RNC is the key equipment of the radio access network...
