Digital cellular telecommunications system (Phase 2+); Universal Mobile Telecommunications System (UMTS); Policy control over Go interface (3GPP TS 29.207 Version 5.5.1 Release 5)
The present document provides the stage 3 specification of the Go interface. The functional requirements and the stage 2 specifications of the Go interface are contained in 3GPP TS 23.002 [2] and 3GPP TS 23.207 [3]. The Go interface is the interface between the GGSN and the Policy Decision Function (PDF). The present document defines: - the protocol to be used between PDF and GGSN over the Go interface; - the signalling interactions to be performed between PDF and GGSN over the Go interface; - the information to be exchanged between PDF and GGSN over the Go interface.
