1. Claims1st, a kind of network handover process method, it is characterised in that including:

  • Target evolution base station receives the identification information that user equipment is sent, and the identification information distributes to the user equipment by source evolution base station;

    When the identification information that the identification information that the target evolution base station is present with the user equipment is sent is consistent, the parameter distributed for the user equipment is sent to the user equipment, proceeds handover process.2nd, network handover process method according to claim 1, it is characterized in that, the identification information that the target evolution base station is present is sent to the target evolution base station by the source evolution base station by handover request message, or is sent to the target evolution base station after the Radio Link Failure when user equipment and the source evolution base station by the source evolution base station.3rd, network handover process method according to claim 1, it is characterised in that also include:

    The completion message that reconfigures of the user equipment reply is received, and handoff completion message is sent to mobile management entity;

    After the switching for receiving mobile management entity transmission completes confirmation message resource release message is sent to source evolution base station.4th, network handover process method according to claim 3, it is characterised in that when there is other candidate target evolution base stations, the resource release message is further sent to other candidate target evolution base stations by the source evolution base station.5th, the network handover process method according to any one of Claims 1-4, it is characterised in that the identification information that the user equipment is sent includes any of following information or its combination:

    Cell-radio network temporary identifications information, Temporary Mobile Subscriber Identity, the identity of other user equipmenies, cell-of-origin identity and source evolution base station identity.6th, network handover process method according to claim 1, it is characterised in that the network handover process method further comprises:

    It is consistent with the identification information that the user equipment is sent when being not present in the target evolution base stationDuring identification information, terminate handover process.7th, a kind of network switching processing unit, it is characterised in that including:

    Receiving module, the identification information for receiving user equipment transmission, the identification information distributes to the user equipment by source evolution base station;

    Sending module, for when the target evolution base station is in the presence of the identification information consistent with the identification information that the user equipment that the receiving module is received is sent, the parameter distributed for the user equipment is sent to the user equipment, proceeds handover process.8th, network switching processing unit according to claim 7, it is characterised in that the network switching processing unit further comprises:

    Acquisition module, for obtaining the identification information that the source evolution base station is sent by handover request message, or obtains the identification information that the source evolution base station is sent after the Radio Link Failure when user equipment and the source evolution base station.9th, network switching processing unit according to claim 7, it is characterised in that the identification information that the user equipment that the receiving module is received is sent includes any of following information or its combination:

    Cell-radio network temporary identifications information, Temporary Mobile Subscriber Identity, the identity of other user equipmenies, cell-of-origin identity and source evolution base station identity.10th, a kind of communication system, it is characterised in that including user equipment, source evolution base station and target evolution base station;

    The user equipment is used for after Radio Link Failure is detected, and finds Target cell, and the identification information by the source evolution base station for its distribution is sent to the corresponding target evolution base station of Target cell;

    The target evolution base station is used to judge when the identification information that the identification information that itself is present with the user equipment is sent is consistent, the parameter distributed for the user equipment is sent into the user equipment, proceeds handover process.11, communication system according to claim 10, it is characterized in that, the source evolution base station is additionally operable to send identification information to the target evolution base station by handover request message, or after Radio Link Failure with the user equipment, identification information is sent to the target evolution base station.12nd, the communication system according to claim 10 or 11, it is characterised in that the target evolution base station is additionally operable to radio bearer configuration parameter being sent to the user equipment, and proceeds handover process;

    The source evolution base station is used to the identification information for distributing to user equipment being sent at least one candidate target evolution base station.
