Claim
1. A method for information transfer, comprising:
determining, by a source Mobility Management Network Element (MMNE) of a source Access Network (AN), a version number of a GPRS Tunneling Protocol (GTP) used between the source MMNE and a destination MMNE of a destination AN; and
transmitting, by the source MMNE, user information corresponding to the version number of the GTP used between the source MMNE and the destination MMNE to the destination MMNE;
wherein when the GTP version number is GTPV2, the user information corresponding to the version number of the GTP is user information corresponding to a higher version AN, or when the GTP version number is one of GTPV1 and GTPV0, the user information corresponding to the version number of the GTP is user information corresponding to a lower version AN; and
wherein the user information corresponding to the lower version AN comprises Packet Data Network Gateway (P-GW) information, and the user information corresponding to the higher version AN comprises both P-GW information and Serving Gateway (S-GW) information.
2. The method of claim 1, wherein when the source AN is of higher version and the destination AN is of lower version, the method further comprises:
transmitting, by the source MMNE, a Delete Bearer Request message to an S-GW;
deleting, by the S-GW, bearer resource used by a user; and
returning, by the S-GW, a Delete Bearer Response message to the source MMNE.
3. The method of claim 1, wherein when the destination AN is of higher version and the source AN is of lower version, the method further comprises:
selecting, by the destination MMNE, an S-GW;
transmitting, by the destination MMNE, a Create Bearer Request to the S-GW; and
receiving, by the destination MMNE, a Create Bearer Request Response message from the S-GW.
4. A device for information transfer comprising:
a determination module, configured to determine a version number of a GPRS Tunneling Protocol (GTP) used between a source Mobility Management Network Element (MMNE) and a destination MMNE, and to transmit a determination result to an Information Element (IE) generation module;
the IE generation module, configured to generate an IE carrying user information, the user information comprising user information corresponding to the version number of the GTP used between the source MMNE and the destination MMNE;
a transmission module, configured to transmit the IE generated by the IE generation module to the destination MMNE;
a receiving module, configured to receive the IE carrying the user information from the source MMNE; and
a processing module, configured to obtain user information corresponding to a version of a local AN from the IE received by the receiving module;
wherein user information corresponding to a lower version AN comprises Packet Data Network Gateway (P-GW) information, and user information corresponding to a higher version AN comprises Serving Gateway (S-GW) information.
