1. Claim1st, a kind of method for realizing location updating, it is characterised in that methods described includes:

  • Receive serving radio network subsystems SRNS transmissions comprises at least hybrid position update instruction and routing area identifier RAI Routing Area Update request message, and the Routing Area Update request message including at least hybrid position update instruction and RAI is that generation after the RAI is added in the Routing Area Update request message including at least hybrid position update instruction that the mobile terminal received is sent by the SRNS;

    The RAI is obtained from the Routing Area Update request message including at least hybrid position update instruction and RAI and Routing Area Update is carried out according at least to the RAI;

    The address of position area the identification code LAI and Visited Location Registor VLR of 2G network systems residing for the mobile terminal are obtained according at least to the Routing Area Update request message including at least hybrid position update instruction and RAI;

    The location area updating request message including at least the hybrid position update instruction and the LAI is sent to the corresponding VLR in the address of the VLR, so that the corresponding VLR in the address of the VLR realizes location area updating according at least to the location area updating request message.2nd, according to the method described in claim 1, it is characterized in that, when the Routing Area Update request message including at least hybrid position update instruction and routing area identifier RAI also monitors the position area identification code LAI obtained comprising mobile terminal in 2G network systems, the address for obtaining position area the identification code LAI and Visited Location Registor VLR of 2G network systems residing for the mobile terminal according at least to the Routing Area Update request message including at least hybrid position update instruction and RAI includes:

    The LAI of 2G network systems residing for the mobile terminal is obtained from the Routing Area Update request message including at least hybrid position update instruction and routing area identifier RAI;

    According to the LAI and VLR distribution principle pre-saved, the address of the VLR of 2G network systems residing for mobile terminal is obtained.3rd, according to the method described in claim 1, characterized in that, the address for obtaining position area the identification code LAI and Visited Location Registor VLR of 2G network systems residing for the mobile terminal according at least to the Routing Area Update request message including at least hybrid position update instruction and RAI includes:

    According to the RAI and the Routing Area number preserved, the LAI of 2G network systems residing for the mobile terminal is obtained;

    According to the LAI and VLR distribution principle pre-saved, 2G nets residing for mobile terminal are obtainedThe VLR of network system address.4th, a kind of method for realizing location updating, it is characterised in that including:

    Receive the location area updating request message including at least hybrid position update instruction and position area identification code LAI, the location area updating request message is to be asked by the serving GPRS support node SGSN of 3G network system and sent in response to the Routing Area Update that SRNS is sent, and the Routing Area Update request is generated by the SRNS in the Routing Area Update request message including at least hybrid position update instruction that the mobile terminal received is sent after addition RAI;

    LAI is obtained from the location area updating request message and location area updating is realized according at least to the LAI.5th, method according to claim 4, it is characterised in that the location area updating request message also includes authentication information, described to realize that location area updating includes according at least to the LAI:

    The mobile terminal is authenticated according at least to the authentication information;

    After authenticating successfully, LAI is obtained from the location area updating request message and location area updating is realized according at least to the LAI.6th, a kind of serving GPRS support node, it is characterised in that including:

    Route Area request message receiving module, the Routing Area Update request message for comprising at least hybrid position update instruction and routing area identifier RAI for receiving serving radio network subsystems SRNS transmissions, the Routing Area Update request message including at least hybrid position update instruction and routing area identifier RAI is to be added to generate after the RAI in the Routing Area Update request message including at least hybrid position update instruction that the mobile terminal received is sent by the SRNS;

    Routing Area Update module, for obtaining the RAI from the Routing Area Update request message for comprising at least hybrid position update instruction and RAI that the receiving module is received and carrying out Routing Area Update according at least to the RAI;

    Acquisition module, the address for obtaining position area the identification code LAI and Visited Location Registor VLR of 2G network systems residing for the mobile terminal according at least to the Routing Area Update request message including at least hybrid position update instruction and RAI;

    Sending module, for sending the location area updating request message including at least the hybrid position update instruction and the LAI to the corresponding VLR in the address of the VLR, so that the corresponding VLR in the address of the VLR realizes location area updating according at least to the location area updating request message.7th, serving GPRS support node according to claim 6, it is characterized in that, the acquisition module is specifically for when the Routing Area Update request message including at least hybrid position update instruction and routing area identifier RAI also monitors the LAI obtained comprising mobile terminal in 2G network systems, from the receiving module receive Routing Area Update request message in obtain the LAI of 2G network systems residing for the mobile terminal, and according to the LAI and VLR distribution principle pre-saved, obtain the address of the VLR of 2G network systems residing for mobile terminal.8th, serving GPRS support node according to claim 6, it is characterized in that, the acquisition module is specifically for according to the RAI and the Routing Area number preserved, obtain the LAI of 2G network systems residing for the mobile terminal, and according to the LAI and VLR distribution principle pre-saved, obtain the address of the VLR of 2G network systems residing for mobile terminal.9th, a kind of Visited Location Registor, it is characterised in that including:

    Position area request message receiving module, for receiving the location area updating request message including at least hybrid position update instruction and position area identification code LAI, the location area updating request message is to be asked by the serving GPRS support node SGSN of 3G network system and sent in response to the Routing Area Update that SRNS is sent, and the Routing Area Update request message is generated by the SRNS in the Routing Area Update request message including at least hybrid position update instruction that the mobile terminal received is sent after addition RAI;

    Location area updating module, the LAI that the location area updating request message for being received according at least to the position area request message receiving module is included realizes location area updating.10th, Visited Location Registor according to claim 9, it is characterised in that when the location area updating request message also includes authentication information, then, described device also includes:

    Authentication module, for being authenticated according to the authentication information to the mobile terminal;

    Shellfish '"'"' J, the location area updating module is specifically for after the authentication module is authenticated successfully, the LAI that the location area updating request message received according at least to the location area updating request message receiving module is included realizes location area updating.
