Patent Images
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.

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. - View Dependent Claims (5)

6. A method for information transfer, comprising:
-
transmitting, by a source Mobility Management Network Element (MMNE) of a source Access Network (AN), both user information corresponding to a lower version AN and user information corresponding to a higher version AN to a destination MMNE of a destination AN, when the source AN is of higher version; wherein the user information corresponding to the lower version AN comprises P-GW information and the user information corresponding to the higher version AN comprises both P-GW information and Serving Gateway (S-GW) information. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)
