gprsSSF GPRS Service Switching Function
The SSF and SCF functions within GSM are termed the gsmSSF and gsmSCF. These are interconnected by CAP (CAMEL Application Part) interfaces which in turn utilize the services of SS7 (Signalling System No.7) to transport the CAMEL information flows. The functionality of the CAMEL Service Environment defined in Phase 3 enables the gsmSCF to interact with GPRS. This interaction is made possible through the addition of the gprsSSF which resides at the SGSN.
