Description
Technical field
The present invention relates to the mobile communication technology field, relate in particular to the data acquisition technology in a kind of attaching process.
Background technology
Evolved packet system (Evolved Packet System, EPS) third generation collaborative project (3rdGeneration Partnership Project, 3GPP) connecting system comprises universal terrestrial access network (Universal Terrestrial Radio Access Network, UTRAN), GSM EDGE Radio Access Network network (GSM/EDGE Radio Access Network, GERAN), evolved universal terrestrial radio access network (Evolved Universal Terrestrial Radio Access Network, E-UTRAN), or the like.
Initially adhere in (Initial Attach) process at the defined E-UTRAN of TS23.401, spell out, new Mobility Management Entity (Mobility Management Entity, MME) to home subscriber servers (Home Subscriber Server, HSS) send the position and upgrade (Update Location) message, satisfy one of following three conditions:
1) new MME is different from subscriber equipment (User Equipment, old MME during UE) attachment removal (Detach);
2) there is not the effectively signatory context (Context) of UE among the new MME;
3) change has taken place in the terminal iidentification of UE.
Wherein, carry in the Update Location message MME sign, IMSI International Mobile Subscriber Identity (International Mobile Subscriber Identifier, IMSI) and terminal iidentification.The signatory context of UE is meant the subscription data (Subscriber Data) of the UE that MME stores, for example UE allows APN (the Access Point Name of visit, APN), corresponding to signatory packet data network gateway (the Packet Data Network Gateway of this APN, PDN-GW) address information, or the like.
The Attach of UE is divided into two types: one type is Initial Attach, is also referred to as start usually and adheres to (Power On Attach), is meant the Attach that UE start back is done; Another kind of type is to switch to adhere to (Handover Attach), is meant that UE switches to the Attach that 3GPP connecting system (for example E-UTRAN connecting system) is done from non-3GPP connecting system.The processing difference that this Attach of two types requires network to do: wherein Handover Attach requires network to guarantee after the Attach process, the IP of UE connects still will keep continuity, require APN that UE inserted still identical with the APN that inserted in the non-3GPP connecting system, and the IP address of UE can not be released, and uses the PDN GW identical with non-3GPP connecting system etc.; And Initial Attach sets up a default bearer (Default Bearer) to default (Default) APN for UE, distribute an Internet Protocol (Internet Protocol for UE simultaneously, IP) address, IP address can be IPv4 (IP version 4) address or IPv6 (IP version 6) address or IPv4+IPv6 address.
TS23.401 stipulates, in the Attach process, if the presently used PDN GW of UE address is different from the signatory PDN GW address of UE, and signatory support of UE switch to non-3GPP connecting system from the 3GPP connecting system, and then MME need pass to HSS with presently used PDN GW address information.Presently used PDN GW address is stored in the session management context of MME, and the signatory PDN GW address of UE is stored in the subscription data of UE.
TS23.401 stipulates, after UE switches to non-3GPP connecting system from E-UTRAN connecting system (3GPP connecting system), discharge all EPS carryings of UE, UE and the MME mobility management states of UE are set to attachment removal state (EMM-DEREGISTERED).After the mobility management states of MME UE is set to EMM-DEREGISTERED, MME will only keep MM Context and the subscription data of this UE, and the session management context of UE is all with deleted.The MM Context of UE is meant the data message relevant with the mobile management of this UE, and MM Context comprises safe context, data messages such as the employed key of storage UE, cryptographic algorithm in the safe context.After after a while, MME will delete MM Context and the subscription data of UE, and send removing (Purge) message to HSS, and this moment, MME did not store any information relevant with this UE.
Regulation according to existing TS23.401, suppose that UE at first is linked into the EPS system by Initial Attach process from E-UTRAN connecting system (3GPP connecting system), and used the PDN GW address that is different from subscription data, and signatory support of UE switches to non-3GPP connecting system from the 3GPP connecting system; Then, after UE switched to non-3GPP connecting system from E-UTRAN connecting system (3GPP connecting system), MME discharged all EPS carryings of UE, and UE and the MME mobility management states of UE are set to EMM-DEREGISTERED.After the mobility management states of MME UE is set to EMM-DEREGISTERED, MME only will keep MM Context and the subscription data of this UE, and the session management context of UE is all with deleted.After this, when UE when non-3GPP connecting system switches back the E-UTRAN connecting system again, UE will carry out Handover Attach process, and the MME of UE Attach this moment is identical with employed MME before the switching, and this MME does not also send Purge message to HSS, does not delete MM Context and the subscription data of UE yet.But this moment, this MME does not have the session management context, does not switch preceding employed PDNGW address information so store UE.
As seen through the above analysis, when UE when non-3GPP connecting system switches back the E-UTRAN connecting system again, UE carries out in the Handover Attach process, if according to the requirement of the E-UTRAN Initial Attach process of TS23.401 definition, three conditions that send Update Location message this moment all do not satisfy:
1) UE does not change MME, and promptly new MME and old MME are same MME;
2) the signatory context of UE is still effective among the MME;
3) terminal iidentification of UE does not change.
This stylish MME does not need to carry out interacting message with HSS, and it is that UE sets up corresponding EPS carrying that new MME uses the signatory PDN GW address in the subscription data of storing, and the current PDN GW address that is different from subscription data of still using of UE.Therefore, this has just caused the IP of UE to connect and can not obtain keeping, and professional continuity has been suffered destruction.
