CISCO-GPRS-ACC-PT-MIB
This MIB module supports access point configuration for GGSN in a GPRS system. GPRS [1] is a GSM network providing mobile wireless data communication services. GGSN is the Gateway GPRS Support Node in the GPRS architecture. It provides interworking with external packet-switched networks - PDNs or other data networks. GGSN is a software extension of a router. A GGSN provides data access for its mobile subscribers to parts of the data network identified by the list of APNs configured on the node. The following diagram illustrates the network elements in a GPRS network, and the interfaces between them: +=====+ +======+ +======+ +=====+ | BSS |----| SGSN |--Gn--| GGSN |--Gi--| PDN | +=====+ +======+ +======+ +=====+ ^ ^ /|\ /|\ | | | Visited access +--------+ | provider network | Access | | | point | \|/ | table | V +--------+ +=====+ | MS | +=====+ Access points must be configured on the GGSN. The Access Point Name is defined in GSM 03.03 [2] and consists of two parts, the APN Network Identifier and the APN Operator Identifier (more details in the object description in this MIB module). The cgprsAccPtTable contains the list of APNs supported by this GGSN and a set of engineering parameters that define the access point's operation. This MIB is also supported in the Evolved Packet Core(EPC) architecture. The details of this architecture is discussed in CISCO-EPC-GATEWAY-MIB description. Hence, the MIB will be supported by GGSN Gateway, PDN Gateway(PGW), Serving Gateway(SGW) and a combined PGW and SGW Gateway SPGW(SGW PGW Gateway).
