Abstract
A method for information transfer includes: determining, by a source Mobility Management Network Element (MMNE) of a source Access Network (AN), version number of 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. The embodiment of the invention also provides a device for information transfer. With the embodiment of present invention, corresponding user information transfer may be realized.
Claims18
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.
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 GTP used between the source MMNE and the destination MMNE;
- and
- a transmission module, configured to transmit the IE generated by the IE generation module to the destination MMNE.
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 second version AN and user information corresponding to a first version AN to a destination MMNE of a destination AN, when the source AN is of first version, wherein the first version is higher than the second version.
