Description
Technical field
The present invention relates to the mobile communication technology field, relate in particular to a kind of method and device that in attaching process, obtains ID.
Background technology
(Attach) process of adhering to of subscriber equipment (UE, User Equipment) is the process that UE is registered to evolved packet system (EPS, Evolved Packet System).For example, when UE started shooting, UE was registered in the EPS system through the Attach process, to accept the service that the EPS system provides.
When UE initiated the Attach process, a kind of situation was that UE might former register the EPS system, like UE start-up logging on daytime to the EPS system; After this UE shutdown in evening, the next morning is when this UE starts shooting once more; UE will carry out the Attach process, be registered to this EPS system again.
UE is in the Attach process; Might be registered to the Mobility Management Entity (MM/E in the EPS system; Mobility Management Entity), also might be registered to Serving GPRS Support Node (GPRS, Serving GPRS Support Node) in the EPS system.If that UE was registered in the past is the MME in the EPS system; Then UE is in current Attach processing procedure; Can be in attach request (Attach Request) message that moves control and management entity (MME or GPRS) transmission to network side; The MME of registration distributes to the global unique casual user's sign (GUTI, Globally Unique Temporary Identity) of self before carrying; If that UE was registered in the past is the GPRS in the EPS system; Then UE can be in the Attach Request message that moves the transmission of control and management entity to network side in current Attach processing procedure, and the SGSN of registration distributes to the grouping Temporary Mobile Station Identity (P-TMSI of self before carrying; Packet Temporary Mobile Station Identity); Old Routing Area Identifier (Old RAI, Old Routing Area Identity) and P-TMSI signature (P-TMSI Signature), wherein UE is when being registered to SGSN; SGSN might distribute P-TMSI Signature for UE, also might not can distribute P-TMSI Signature for UE.
UE is in current Attach processing procedure; (GUTI) that carries in the Attach Request message that the mobile control and management entity (MME or GPRS) that is registered to can be sent according to UE be (P-TMSI and Old RAI) perhaps; Be positioned at current Attach and handle the old mobile control and management entity of serving this UE before, this old mobile control and management entity possibly be MME or SGSN.The current mobile control and management entity that is registered to of UE sends identification request (Identification Request) message to old mobile control and management entity then; To ask old mobile control and management entity, carry (GUTI) that UE reports perhaps (P-TMSI and OldRAI) in this Identification Request message of wherein sending for the IMSI number of this UE is provided self.Old mobile control and management entity according to the UE current register to the Identification Request message sent of mobile control and management entity in (GUTI) that carry perhaps (P-TMSI and Old RAI); Confirm self storage to context (Context) that should UE; And in Context that this is confirmed, extract its storage to International Mobile Subscriber Identity (IMSI that should UE user; International Mobile Subscriber Identity), and with the IMSI that extracts be encapsulated in identification response (Identification Response) message that feeds back to the mobile control and management entity that the UE current register arrives.If old mobile control and management entity according to the UE current register to the Identification Request message sent of mobile control and management entity in (GUTI) that carry perhaps (P-TMSI and Old RAI); Do not inquire self to should UE the Context of storage, then feed back to the UE current register to the Identification Response message of mobile control and management entity in indication IMSI do not find (IMSI not known).If the UE current register to the mobile control and management entity Identification Response message finding to receive in carry " IMSI not Known " information; Then can send identify label request (Identity Request) message to UE; The IMSI of himself is provided with request UE; Respond the mobile control and management entity that identify label response (Identity Response) message arrives for the UE current register after this message that UE receives, carry the IMSI of this UE in this Identity Response message.
Can old mobile control and management entity provide the IMSI of UE to the mobile control and management entity that the UE current register arrives, and depends on the attachment removal time of UE on old mobile control and management entity.Usually when UE moved the attachment removal of control and management entity from a Geju City, Context a period of time that this old mobile control and management entity will keep this UE, this time was prepared by operator usually, for example 24 hours.Served as this section after the period, old mobile control and management entity will be deleted the Context of the UE of this reservation, and send removing (Purge) message to home subscriber server (HSS, Home Subscriber Server).If after this; The mobile control and management entity that the UE current register arrives sends Identification Request message to old mobile control and management entity; Then old mobile control and management entity will be responded the mobile control and management entity that " IMSI not Known " indication arrives for the UE current register owing to search less than to Context that should UE.If before the Context of the UE that old mobile control and management entity deletion keeps; The mobile control and management entity that the UE current register arrives sends Identification Request message to old mobile control and management entity, and then old mobile control and management entity will provide the IMSI of this UE in Identification Response message.
In fact, the UE current register to mobile control and management entity through sending Identification Request message to old mobile control and management entity to obtain the IMSI of this UE, be a kind of safeguard measure that system realizes network security.In fact UE can be directly to current register to mobile control and management entity its IMSI is provided; But direct interface aloft transmits the permanent identification IMSI of UE; Then possibly there is the risk of being stolen the IMSI of this UE by the network attack person; That is to say that the mobile control and management entity that the UE current register arrives passes through to send Identity Request message to UE; UE provides its IMSI with request, and UE responds Identity Response message and carries the fail safe that the process of the IMSI of self can impair system therein, increases the potential safety hazard of system.
Therefore in above-mentioned prior art processing procedure; UE is when initiating the Attach process; If the time of origin of current Attach is long apart from the time of origin that removed Attach last time; Just might exist the UE current register to mobile control and management entity can not get access to the IMSI of UE from old mobile control and management entity, but need through sending Identity Request message to UE, so that UE transmits the problem that self IMSI gives the mobile control and management entity of current register through the air interface mode; So will certainly increase IMSI by the risk that the network attack person steals, increase the potential safety hazard of system.
In addition; When UE initiates Attach; If from being not registered to the EPS system, for example the user has just bought a universal subscriber identity module card (USIM, Universal Subscriber Identity Module) from the operator there before the UE; When UE used this USIM to start shooting initiation Attach for the first time, then this UE just belonged to situation about never crossing in the EPS system registry.Also do not propose in this case in the standard at present, how UE initiate to let when Attach handles the UE current register to mobile control and management entity obtain the practical scheme of the IMSI of UE.
Summary of the invention
