Abstract:
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.
