In order to support machine and machine (Machine to Machine, M2M) communication, 3GPP tissue has proposed MTC communication system framework as shown in Figure 1 at present.From functional hierarchy aspect, it is mainly comprised of machine type communication (Machine Type Communication, MTC) server (MTC Server), 3GPP mobile communications network and MTC terminal (MTC Device) three parts.MTC Server is outside in 3GPP network system scope, and by Virtual network operator or third party service provider management and control, 3GPP network connects for MTC terminal provides to the network of MTC Server.
MTC interconnecting function (MTC-Inter working function, MTC-IWF) entity is network edge node, to external shield the details of 3GPP network topology.It is mutual that the MTCsp interface of this entity by new definition and MTC Server carry out control signal, by the signaling protocol on relaying or conversion MTCsp interface, calls the specific function that 3GPP network provides, and for MTC Server provides transparent operation, controls service.
By MTCsp control signal interface, MTC Server can send control signaling to 3GPP network, request to terminal trigger, control, manage, the operation such as maintenance, thereby realize MTC traffic performance.For example, for MTC terminal, trigger (MTC device triggering) characteristic, MTC Server can send trigger request to MTC-IWF entity by MTCsp interface, to ask network to initiate to trigger to target terminal, makes it set up and communicate by letter with MTC Server.When to MTC terminal transmit operation instruction, MTCServer needs to operate involved object MTC terminal by unique identification.
In 3GPP network, signing use IMSI International Mobile Subscriber Identity between user and Virtual network operator (International Mobile Subscriber Identity, IMSI), this sign is stored in universal subscriber identity module (User Service Identity Module, USIM) card.Insert the terminal of usim card when access network, can use the identity of IMSI sign oneself.Yet in order to protect user's privacy, system wireless interface should reduce user's IMSI in principle as far as possible.Therefore; evolved packet system (Evolved Packet System; EPS) in system; mobile management entity (Mobility Management Entity; MME) be global unique temporary identity symbol (Globally Unique Temporary ID of terminal distribution; GUTI) for the protection of user's IMSI, GUTI also can be designated EPS network and the MME that user provides service simultaneously.GUTI is mainly comprised of following two parts roughly: GUTI=GUMMEI+M-TMSI, GUMMEI is global unique MME sign (Globally Unique MME Identity), for unique identification, be the MME of terminal distribution GUTI, M-TMSI is MME Temporary Mobile Subscriber Identity (MME-Temporary Mobile SubscriberIdentity), for the terminal of this MME of unique identification.
In order to communicate with MTC terminal, first MTC Server needs recognition purpose MTC terminal uniquely.A kind of direct and feasible scheme is: MTC Server carrys out recognition purpose terminal with IMSI.Yet, at network, to the external interface of MTC Server, directly use IMSI to exist the security risk that IMSI is stolen.During use, system interface has been proposed to higher security reliability requirement.In addition, in the situation that MTC Server is third party service provider management and control, allow MTC Server directly to use IMSI to exist the security risk that IMSI exposes, be unfavorable for protecting user's privacy.
Therefore,, in current standard discussion process, propose terminal iidentification to be divided into outside sign and internal indicator.Internal indicator mainly refers to IMSI (certainly also may have other), and may there is various ways in outside sign, as universe name (Fully Qualified Domain Name, FQDN), unified resource name (UniformResource Name, URN), unified resource sign (Uniform Resource Identifier, SIP URI) etc., its main purpose is to be convenient to user's memory and use.
In realizing process of the present invention, inventor finds to exist in prior art following technical problem:
For the solution of support terminal identified problems, MTC-IWF and MTC Server need can the IMIS/GUTI binding with this MTC terminal by the outside sign of MTC terminal.Yet, in standards meetings, not yet this problem is discussed at present, in existing protocol, also not yet provide the solution of this problem.
