The information transferring method of mobile communications network and device
Technical field
The present invention relates to a kind of signaling network that uses and realize information transferring method and device that the user roams between a plurality of mobile communications networks, relate in particular to a kind of CDMA of use signaling network and GSM signaling network realize that the user roams between cdma network and GSM network information transferring method and device.
Technical background
GSM and CDMA are the second generation mobile communications networks of present extensive use.Because they adopt different communication standards separately, therefore need change terminal, Subscriber Identity Module and Subscriber Number when wanting to utilize cdma network to communicate when roam into the zone that cdma network covers the signatory user of GSM, the area that the user who contracts at CDMA 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 network, 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, main realize following function: (1) with the network entity in the GSM network (such as, service universal grouping wireless business supporting node (SGSN) 10, mobile switching centre (MSC) 20, Visited Location Registor (VLR) 30, attaching position register (HLR) 40, authentication center (AuC) 50, GSM short message service GMSC (gateway mobile switching center) (SMS-GMSC) 60, GSM short message service interoperability (SMS-IWMSC) 70 of mobile switching centre or Short Message Service Center (SMS-SC) 80) MAP of following the GSM network using (MAP:Mobile ApplicationPart) protocol signaling that sends to cdma network converts the signaling of following the ANSI-41 MAP that cdma network adopts to; (2) with the network entity in the cdma network (such as, mobile switching centre (MSC) 90, Visited Location Registor (VLR) 100, attaching position register (HLR) 110, authentication center (AC) 120, short message service center (MC) 130) signaling of following the ANSI-41 MAP that cdma network adopts that sends to the GSM network converts the signaling of the GSM MAP of following the GSM network using to; (3) auxiliary GSM network entity and cdma network entity interaction user data (such as, customer position information, user service data and called routing iinformation etc.).
Though 3GPP2 X.P0023 standard specified in more detail cdma network entity and GSM network entity by interoperability functional unit (IIF) carry out information (such as, signaling and user data etc.) transmission method, how not to be connected with the GSM network entity but this information transferring method spells out the cdma network entity with interoperability functional unit (IIF).
Than the connectivity scenario that is easier to expect is that all interoperability functional units (IIF) are set up into a brand-new network separately, realizes being connected of cdma network entity and GSM network entity and interoperability functional unit (IIF) by this brand-new network then.In order to realize this connectivity scenario, must drop into huge fund and build this brand-new network, while existing C DMA network entity and GSM network entity are done corresponding modification and are adapted to this network, because the quantity of cdma network entity and GSM network entity is very big, therefore the corresponding workload of changing is very big, thereby this connectivity scenario does not have practicality.
As everyone knows, CDMA (or GSM) network has the signaling network of oneself, i.e. CDMA (or GSM) signaling network.CDMA (or GSM) signaling network is made of Signalling Transfer Point (STP:Signaling Transfer Point) usually, and the responsible information that CDMA (or GSM) network entity is sent is transmitted to other CDMA (or GSM) network entity.
Fig. 2 shows the schematic diagram of CDMA (or GSM) signaling network.As shown in Figure 2, CDMA (or GSM) network entity 145 directly is connected with 150 with Signaling Transfer Point 140 respectively with 155, Signaling Transfer Point 140 and 150 is also referred to as Low Level Signaling Transfer Point LSTP (LSTP:Low Signaling Transfer Point), and generally each province is provided with a Low Level Signaling Transfer Point LSTP (LSTP).When CDMA (or GSM) network entity 145 wants that information sent to CDMA (or GSM) network entity 155, it at first sends to information direct-connected Signaling Transfer Point 140, then, if Signaling Transfer Point 140 directly links to each other with Signaling Transfer Point 150, then Signaling Transfer Point 140 can directly be transmitted to Signaling Transfer Point 150 with this information; If Signaling Transfer Point 140 does not directly link to each other with Signaling Transfer Point 150, then Signaling Transfer Point 140 is transmitted described information by 1 to N Signaling Transfer Point 160 that does not directly link to each other with network entity and is given Signaling Transfer Point 150, wherein, Signaling Transfer Point 160 is also referred to as HSTP High Signaling Transport Point (HSTP:High Signaling Transfer Point), generally a plurality of provinces are formed a Da Qu, each among each Da Qu economized a shared HSTP High Signaling Transport Point (HSTP).The described information that last Signaling Transfer Point 150 will be received is transmitted to network entity 155.
Consider the existing connected mode of CDMA (or GSM) network entity and CDMA (or GSM) signaling network, CDMA (or GSM) network entity can pass through CDMA (or GSM) signaling network and link to each other with interoperability functional unit (IIF).
