Abstract

The invention discloses a mapping method, a device and a system for terminal identifications. The mapping method includes that a machine type communication interworking function (MTC IWF) stores a mapping relation between an internal identification (ID) and an external ID of user equipment (UE); and the MTC IWF completes conversion from the external ID to the internal ID of the UE according to the mapping relation while receiving information sent to the UE. By using the mapping method, the device and the system, the mapping relation of the internal ID and the external ID of the UE can be stored in the MTC IWF rather than in a home location register/home subscriber server (HLR/HSS), when the external ID of the UE is needed to change on the application layer out of certain purposes, the HLR/HSS is not needed to be informed to change signing data, therefore the external ID of the UE is prevented from being closely coupled on the internal ID of the UE, and control flexibility of the application layer on the external ID of the UE is improved.

Description

The mapping method of terminal iidentification, Apparatus and system

Technical field

The present invention relates to the communications field, in particular to a kind of mapping method, Apparatus and system of terminal iidentification.

Background technology

In mobile communication, application server (Application Server, AS) often needs and user terminal (User Equipment, UE) communication.In correlation technique, the communication of application service and user terminal has two kinds of approach: by user's face communication (referred to as the communication of user's face) of both sides IP address realization, the chain of command communication (referred to as the chain of command communication) of process mobile network chain of command node transfer.In the communication of user's face, application server and user terminal are known the other side's IP address mutually, and this IP address can and, thereby can directly come communication by the IP address.The chain of command communication is applied to usually that application server is wished initiatively and user terminal is set up communication, but application server and do not know the situation of the IP address of user terminal.In this case, application server request network addressing user terminal, and through network control node to terminal issue specific message with the excited users terminal initiatively and application server set up communication.

In machine type communication (Machine Type Communication, MTC) communication, the communication between this application server and the user terminal is very general, especially the communication of the application server sensing user terminal of initiatively initiating.In the chain of command communication, application server needs and mobile network's node is initiatively set up communication, and request mobile network's node is on behalf of the addressed user terminal and issue activation message.Still and, application server often is positioned at the network-external of mobile operator control, in order to shield network topology structure, mobile operator can dispose interactive gateway (the MTC Interworking Function of a special machine type communication, MTC IWF), this MTC IWF has realized hiding of network topology structure, unified application programming interface (Application Programming Interface is provided, API) function is called to application server, receives and transmit the activation request that application server mails to user terminal.

Fig. 1 is the configuration diagram that is linked into packet domain according to terminal under the prior art, as shown in Figure 1, this structure has related to: UE, universal mobile telecommunications system (Universal Mobile Telecommunications System, UMTS) land radio access web (UMTS Terrestrial Radio Access Network, UTRAN), the land radio access web of evolution (Evolved UMTS, E-UTRAN), service universal grouping wireless service technology (General Packet Radio Service, GPRS) support node (Serving GPRS Supporting Node, SGSN), Mobility Management Entity (Mobile Management Entity, MME), attaching position register (Home Location Register, HLR)/home subscriber server (Home Subscriber Server, HSS), Gateway GPRS Support Node (Gateway GPRS Supporting Node, GGSN), gateway (ServingGateway, S-GW), grouped data network gateway (Packet Data Network Gateway, P-GW), MTC Communication Gateway (MTC Interworking Function, be MTC IWF), the application server (MTC Server) that is used for the MTC communication, wherein, MTC IWF links to each other by the MTCsp interface with MTC Server.

Hide, provide the unified API except realizing network topology structure, further, MTC IWF also is used for hiding the internal indicator of user terminal in the mobile network and (is generally international mobile subscriber identity (InternationalMobileSubscriberIdentificationNumber, IMSI), international integrated services digital network (the Integrated Service Digital Network of travelling carriage, ISDN) number (Mobile Subscriber InternationalISDN/PSTN number, MSISDN) etc.).Because IMSI is the sensitive information of operator's control, do not wish the network-external node is exposed, thereby operator can require to adopt in the communication outside sign of user terminal between MTC IWF and application server, this external user sign can be universe name (the Fully Qualified DomainName of a user terminal, FQDN), perhaps conversation initialized protocol unified resource sign (Session Initiation Protocol Uniform Resource Identifier, SIP URI) etc.Thereby MTC IWF need to realize the outside sign of user terminal and the mapping between the internal indicator.

In the prior art, the mapping relations of this internal indicator of user terminal and outside sign are stored in user's the subscription data usually, namely be stored among the HLR/HSS, MTC IWF needs and HLR/HSS inquires about these mapping relations or finishes internal indicator and the outside conversion that identifies by HLR/HSS by interface.

Fig. 2 sends activation request according to application server AS in the correlation technique (being also referred to as MTC Server) by the control terminaloriented, uses the flow chart of short message service activated terminals and application server communication, and as shown in Figure 2, this flow process comprises the steps:

Step S202, user terminal is attached to network;

Step S204, after a while, MTC Server wishes activated terminals and this user terminal communication, MTC Server sends activation request to MTC IWF, uses the outside sign ID of this user terminal in activation request, is a SIP URI such as this outside sign;

Step S206, MTC IWF is to the inside ID of HLR/HSS inquiry UE and the mapping relations of exterior I D, and service node (being SGSN/MME);

Step S208, HLR/HSS inquire about the mapping relations of the inside and outside ID of UE from subscription data, HLR/HSS can directly return the inside ID of UE, perhaps returns the pairing of inner ID, an exterior I D;

Step S210, HLR/HSS return the mapping relations of the inside and outside ID of UE to MTC IWF, and the address of current SGSN/MME for user service;

Step S212 after MTC IWF receives returning of HLR/HSS, sends activation request to SGSN/MME, uses the inside ID of UE in this activation request;

Step S214, SGSN/MME is addressed to terminal, sends activation request to UE;

Step S216 after UE receives activation request, initiatively carries out subsequent operation, as: to application server registers, reported data etc.

Fig. 3 is similar flow process, and this flow process comprises the steps:

Step S302, user terminal is attached to network;

Step S304, after a while, MTC Server wishes activated terminals and this user terminal communication, MTC Server sends activation request to MTC IWF, uses the outside sign ID of this user terminal in activation request, is a SIP URI such as this outside sign;

Step S306, MTC IWF sends to HLR/HSS with activation request;

Step S308, HLR/HSS finish exterior I D to the mapping of inner ID according to the mapping relations of inside and outside ID in the subscription data, and activation request is sent to the current SGSN/MME of UE, in this activation request, and the inside ID of the UE that HLR/HSS uses;

Step S310 after MTC IWF receives returning of HLR/HSS, sends activation request to SGSN/MME, uses the inside ID of UE in this activation request;

Step S312, SGSN/MME is addressed to terminal, sends activation request to UE;

Step S314 after UE receives activation request, initiatively carries out subsequent operation, as: to application server registers, reported data etc.

Different with Fig. 2 is, in step S306～S308, MTC IWF sends to HLR/HSS with activation request, HLR/HSS is according to the mapping relations of inside and outside ID in the subscription data, finish exterior I D to the mapping of inner ID, and activation request sent to the current SGSN/MME of UE, and in this activation request, the inside ID of the UE that HLR/HSS uses.

In the prior art shown in Fig. 2,3 flow processs, the mapping relations of inside ID, the exterior I D of UE are that the subscription data as UE is stored among the HLR/HSS, when need to convert the inside ID of UE to from the exterior I D of UE, MTC IWF inquires about the mapping relations of the inside and outside ID of UE from HLR/HSS, and finishes the conversion of ID.Perhaps, by the HLR/HSS Forward-reques, in repeating process, finish the conversion of inside and outside ID.

This technology is stored in the exterior I D of UE in the subscription data regularly, when the exterior I D of UE changes, must again change subscription data.And normally application layer control of the exterior I D of UE when application layer needs the exterior I D of (such as migration name server, business configuration optimization etc.) change UE for some purpose, must notify HLR/HSS to change subscription data.This method closely is coupled to the exterior I D of UE on the inside ID of UE, has lost the flexibility of the exterior I D of application layer control UE, has brought inconvenience.

That subscription data as UE is stored among the HLR/HSS for the mapping relations of inside ID, the exterior I D of UE in the correlation technique, when application layer need to be changed the exterior I D of UE for some purpose, must notify HLR/HSS to change subscription data, this method closely is coupled to the exterior I D of UE on the inside ID of UE, lose the problem of flexibility of the exterior I D of application layer control UE, not yet proposed at present effective solution.

The UE that now with specific embodiment (embodiment 1) embodiment of the invention is provided passes through the PCO mode to the sign of MTC IWF registered UE, and then realizes the handling process of the mapping method of terminal iidentification.Need to prove, the terminal in following examples also can not be the MTC terminal, also can be suitable for for other the terminal of type.

Embodiment 1:

Fig. 5 is the flow chart of determining according to embodiment 1 provided by the invention, and in this example, to MTC IWF registration inside and outside ID, concrete handling process is as follows by the PCO mode for UE.

Step S502, UE be by PCO message, and the exterior I D of UE is sent to GGSN/PGW;

PCO is for agreement protocol configuration parameter between UE and the GGSN/PGW, such as: UE tells the type of the IP agreement that GGSN/PGW supports, version number of GTP agreement etc., and perhaps, UE distributes P-CSCF etc. by PCO to the PGW request.The PCO parameter provides when UE asks PDP/PDN to connect usually, is transparent to GGSN/PGW through SGSN/MME, the only identification of two end points (being UE, GGSN/PGW) between UE and GGSN/PGW, and SGSN/MME is transparent transmission in transmission course.

After step S504, GGSN/PGW receive the exterior I D of UE transmission, to inside ID, the exterior I D of MTC IWF notice UE.

Set up in the process of IP carrying at UE, GGSN/PGW can be known the inside ID of UE, such as IMSI.The inside ID of UE is stored in the context of UE.Receive the exterior I D of UE as GGSN/PGW after, GGSN/PGW is made into a pairing with inside ID, the exterior I D of UE, reinforms the IWF to MTC.

GGSN/PGW can be known MTC IWF in several ways, for example, can adopt following several mode of preferably knowing:

A) in non-roaming situation, GGSN/PGW, MTC IWF all are positioned at home network, and GGSN/PGW can be known by configuration the position of MTC IWF;

B) under roaming condition, if GGSN/PGW is positioned at home network, then GGSN/PGW still can be known by configuration the position of MTC IWF;

C) under roaming condition, if GGSN/PGW is positioned at the visit net, then GGSN/PGW can be known by roaming agreement the position of MTC IWF;

D) under roaming condition, if GGSN/PGW is positioned at the visit net, then GGSN/PGW can notify the IWF to MTC by AAA, PCRF with the pairing of the inside and outside ID of UE.Be positioned at the AAA (being H-AAA) of home network, the position that PCRF (being H-PCRF) can be known according to configuration data MTC IWF herein;

Fig. 6 is a kind of flow chart preferred embodiment of determining according to the embodiment of the invention 1, GGSN/PGW is by above-mentioned several D kind modes of knowing in the mode in this example, namely by the flow chart of AAA to the inside and outside ID of MTC IWF registered UE, its processing procedure has following steps:

Step S602, UE sends PCO message to GGSN/PGW, wherein carries the exterior I D of UE;

Normally, UE sends the PCO parameter when asking PDP/PDN to connect to GGSN/PGW, when namely this process is included in UE request establishment PDP/PDN connection.

After step S604, GGSN/PGW received the PCO message of UE transmission, GGSN/PGW generated the inner/outer ID pairing of UE according to the inside ID of UE, sends to aaa server;

Because there is context in UE at GGSN/PGW, namely there has been the inside id information of UE on the GGSN/PGW, the exterior I D that GGSN/PGW can provide according to this inside ID and UE is paired into the pairing of an inner/outer ID.

When UE in when net visit, GGSN/PGW sends to the AAA (being V-AAA) of visit net with this inner/outer ID pairing, V-AAA is transmitted to this information the AAA (being H-AAA) of home network, H-AAA is transmitted to MTC IWF with this information again.As UE during in home network, V-AAA is H-AAA.

Step S606, receive the inner/outer id information of UE as H-AAA after, register the inner/outer ID of this UE to MTC IWF;

H-AAA can identify according to the IMSI of UE UE and be assigned to which MTC IWF, and perhaps H-AAA can inquire the MTC IWF that UE is assigned with from HLR/HSS, and this information can be used as the subscription data of UE and exists.

Step S608, MTC IWF preserve this sign pair relationhip after receiving the inner/outer id information of the UE that aaa server sends in this locality;

Step S610, after a while MTC Server may use UE exterior I D to MTC IWF initiating terminal activation request, then MTC IWF finishes the exterior I D of UE and the mapping between the inner ID.Be MTC IWF when receiving the message that MTC IWF sends, convert the exterior I D of UE to inner ID.Otherwise, when MTC IWF receives return messages from network, convert the inside ID of UE to exterior I D.

Fig. 7 is another flow chart preferred embodiment of determining according to the embodiment of the invention 1, and GGSN/PGW is by above-mentioned several D kind modes of knowing in the mode in this example, and namely GGSN/PGW comprises by the inside and outside ID of PCRF to MTC IWF registered UE:

Step S702, UE sends PCO message to GGSN/PGW, wherein carries the exterior I D of UE;
