this answer is valid for this question In short is basically carrying siganlling and control infromation between entities e.g MSC to PSTN & MSC to BSC etc.Its benefit in GSM is when BTS received data message from MS which pass to BSC, then BSC relays the message to MSC via C7 signalling links SS7 also called C7.

Signaling System #7 (SS7) is a set of telephony signaling protocols which are used to set up the vast majority of the world's public switched telephone network telephone calls. The main purpose is to set up and tear down telephone calls. Other uses include number translation, prepaid billing mechanisms, short message services, and a variety of mass market services.

1.)High-speed data links (56 Kbps – national; 64 Kbps – international).
2.)Variable length signal units with a maximum size limitation.
3.)Plans to increase link speed to T1 and E1 speeds to be able to handle the increased demands required
of the SS7 network.
