The positional information registration canceling method and the device of mobile communications network
Technical field
The present invention relates to a kind of positional information registration canceling method and device that is used to connect the interoperability functional unit (IIF) of a plurality of mobile communications networks, relate in particular to a kind of positional information registration canceling method and device that is used to connect the interoperability functional unit (IIF) of GSM and cdma network.
Technical background
GSM and CDMA are the second generation mobile communications networks of present extensive use.Because they adopt different communication standards separately, therefore the user who opens an account as GSM roams into the zone of cdma network covering and need change terminal, Subscriber Identity Module and Subscriber Number when wanting to utilize cdma network to communicate, and the area that the user that CDMA opens an account roams into the GSM network coverage too.This has caused very big inconvenience to the user, because the user need be equipped with terminal, user ID card and the Subscriber Number of heterogeneous networks.
When allowing the user between GSM and CDMA, roam, needn't change terminal, user ID card and Subscriber Number and just can be convenient to use the service that GSM network or cdma network provide, third generation affiliate organizes 2 (3GPP2) to propose the 3GPP2 X.P0023 international norm of a kind of GSM of being used for and cdma network interconnection.
Fig. 1 shows the schematic diagram of GSM and cdma network interconnection in 3GPP2 X.P0023 standard.As shown in Figure 1, in 3GPP2 X.P0023 standard, existing GSM and cdma network interconnect by interoperability functional unit (IIF:Interworking andInteroperability Function) 5.Wherein, interoperability functional unit (IIF) 5 is also referred to as G﹠amp; The C gateway, mainly realize following function: (1) is with service universal grouping wireless business supporting node (SGSN) 10 in the GSM network, mobile switching centre (MSC) 20, VLR Visitor Location Register (VLR) 30, attaching position register (HLR) 40, authentication center (AuC) 50, GSM short message service GMSC (gateway mobile switching center) (SMS-GMSC) 60, the MAP of following the GSM network using (the MAP:Mobile Application Part) protocol signaling that GSM short message service interoperability (SMS-IWMSC) 70 of mobile switching centre or Short Message Service Center (SMS-SC) 80 send to cdma network converts the signaling of following the ANSI-41 MAP that cdma network adopts to; (2) signaling of following the ANSI-41 MAP that cdma network adopts that mobile switching centre in the cdma network (MSC) 90, VLR Visitor Location Register (VLR) 100, attaching position register (HLR) 110, authentication center (AC) 120, short message service center (MC) 130 is sent to the GSM network converts the signaling of the GSM MAP of following the GSM network using to; (3) auxiliary GSM and cdma network interactive user positional information, user service data and called routing iinformation etc.
Because the user is when roaming between GSM and CDMA, maintenance customer's positional information is extremely important, thus 3GPP2 X.P0023 standard specified in more detail the renewal process of user position information under the different situations.Below in conjunction with Fig. 2, be example with the updating location information of GSM contracted user in the GSM network of in cdma network, having registered positional information in the past, be described in detail in the renewal process of customer position information in the 3GPP2 X.P0023 standard.
