The MN S-GW receive Update Bearer Response (the more new bearer responses that the CN S-GW are returned）Message, and according to the EPS bearer contexts of the Update Bearer Response information updatings MN, complete the foundation of S-GW carryings matched with the packet.

Wherein, the Update Bearer Response message is the CN S-GW according to the Update Bearer Request message, sent after the renewal for the EPS bearer contexts for completing the CN, wherein EPS Bearer Id for CN (the evolved packet system carrying marks of correspondent node can be carried）, CN S-GW IP for R0 (UP) (correspondent node gateway be mobile node gateway distribution user plane general packet wireless service tunnel protocol tunnel internet protocol address), CN S-GW TEID for RO (UP) (correspondent node gateway be mobile node gateway distribute user plane it is general The tunnel endpoint identifier in packet wireless service tunnel protocol tunnel）And (correspondent node gateway is the tunnel endpoint identifier in the chain of command general packet wireless service tunnel protocol tunnel that mobile node gateway is distributed to CN S-GW TEID for RO (CP)）Etc. information.

Specifically, in embodiment of the present invention, the MN S-GW can send Update Bearer Request message to the CN S-GW in the following manner：

It is that the chain of command GTP tunnel that CN P-GW are distributed is sent by CN S-GW, i.e., the Update Bearer Request message to the CN S-GW is sent by CN S-GW IP for S5/S8, CN S-GW TEID for S5/S8 chain of command GTP tunnel；Or,

Directly the Update Bearer Request message is sent to CN S-GW IP for S5/S8.
