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.
