1. A method of providing GPRS Tunneling Protocol Core (GTPC) optimization, comprising:
sending a first message from a Mobility Management Entity (MME) to a peer node, the first message including a feature name and socket information in a private extension over an interface;
wherein a message format for the first message includes a message type, a Tunnel Endpoint IDentifier (TEID) and a bitmask;
when the peer node supports GTPC optimization, then confirming, by the peer node, by encoding the socket information in a response message and sending the response message to the MME.
