Description
Technical field
The present invention relates to communication technical field, relate in particular to the delet method and the system of a kind of evolved packet system (EPS, EvolvedPacket System) carrying.
Background technology
(Attach) process of adhering to of subscriber equipment (UE) is the process that UE is registered to the EPS system.For example, when UE started shooting, UE was registered to the EPS system by the Attach process, accepted the EPS system service.
The EPS system supports idle state signaling optimization/minimizing (ISR, Idle State Signaling Reduction) function.
When the ISR of UE function activation, this UE is registered to universal terrestrial access network (UTRAN simultaneously, Universal Terrestrial Radio Access Network)/global system for mobile communications (GSM, Global System for Mobile communication)/the enhancing data transfer rate (EDGE of GSM evolution, Enhanced Data rates for GSM Evolution) Radio Access Network (GERAN, GSM/EDGE Radio Access Network) on two user mobile control management entity (UEMCME) corresponding with the difference of E-UTRAN connecting system, just be registered to service universal packet wireless business affair (GPRS simultaneously, General Packet Radio Service) service node (SGSN, Serving GPRS Support Node) and on the Mobility Management Entity (MME, Mobility Management Entity).SGSN and MME all store the EPS bearer context (Context) of UE like this.
When the UE that has activated when the ISR function is in Idle state, UE distributes to the route district (RA of UE at SGSN, Routing Area) and MME distribute to the tracking area (TA of UE, Tracking Area) in the process that moves in the tabulation (List), need not to do the operation of general Routing Area Update or general tracing section updating.When the ISR of UE function activation, the user plane destination node of UE is positioned at gateway (ServingGW).
The ISR function must be supported the UE (being the UE that E-UTRAN and UTRAN/GERAN support simultaneously) of multimode, but network is optional.
The activation of the ISR function of UE side can only be finished in UE is registered to the mobility management process (being TAU or RAU process) of E-UTRAN and UTRAN/GERAN.Behind the ISR function activation, SGSN and MME also will be registered to home signature user server (HSS, Home Subscriber Server) goes up (promptly two registration), mobile management (the MM that the UE storage is relevant with SGSN, MobilityManagement) parameter, as packet TMSI (P-TMSI, Packet TemporaryMobile Station Identity), Routing Area Identifier (RAI, Routing Area Identity) and the parameter of secure context, and the mobile management MM parameter relevant with MME, as tracking area identification (TAI, Tracking Area Identity) tabulation (List), the parameter of the whole world unique (user) temporary mark (GUTI, GloballyUnique Temporary Identity) and secure context.Behind the ISR function activation, SGSN and MME preserve the other side's IP address, thereby the ISR function that can be used as a specific markers sign UE is activated, and SGSN and MME set up respectively and gateway (Serving GW) between control plane, promptly Serving GW preserve simultaneously respectively and MME and SGSN between control plane and corresponding EPS bearer context.
But behind the ISR of UE function activation, when if Serving GW only receives the deleting bearing request of a user mobile control management entity of this UE, deexcitation ISR then, and deletion that stored and EPS bearer context corresponding this UE of this user mobile control management entity, but do not send the process of deleting bearing to PDN GW.After the deexcitation of the ISR of this UE function, when Serving GW receives the deleting bearing request of another user's mobile management control entities of this UE, that stored and EPS bearer context corresponding this UE of this user's mobile management control entities of deletion then, at this moment, because Serving GW no longer has the EPS bearer context with corresponding this UE of Any user mobile management control entities, Serving GW just initiates the process of deleting bearing to PDN GW, make that the not deleted Internet resources of this UE in the EPS network are all deleted.
For example, behind the ISR of UE function activation, when Serving GW receives the deleting bearing request that MME sends over, Serving GW finds that the ISR function of UE activates, the ISR function of this UE of deexcitation then, simultaneously with EPS bearer context (BearerContext) deletion of this UE corresponding that stored with MME, and continuation keeps the EPS Bearer Context of this UE corresponding with SGSN, because Serving GW also remains with the EPS Bearer Context of this UE of SGSN correspondence, so ServingGW can not initiate the delete procedure of EPS carrying to PDN GW.If after this, Serving GW receives the deleting bearing request message that SGSN sends, then Serving GW deletion that stored with EPS bearer context corresponding this UE of SGSN, and then Serving GW initiates the process of deletion EPS carrying to PDN GW, makes that this UE not deleted Internet resources in the EPS network are all deleted.
In the chapters and sections 5.3.2.1 of TS23.401v8.4.1, defined the process that UE adheres in the E-UTRAN initiation, as shown in Figure 1.Step 8 in attaching process shown in Figure 1 has provided the MME that the UE latest requests is adhered to (being called for short new MME) and has sent the various conditions of upgrading location request message to HSS.Has only the renewal location request message of receiving new MME transmission as HSS, and when the updating type of indication is attaching process (being Update Type indicates this is Attach procedure), HSS sends cancel location message to registered old MME and old SGSN in step 9, and the cancellation type is set is the process that old MME and SGSN carry out relevant deleting bearing, i.e. process shown in the step 10.
But, in the condition that provides in the step 8, exist an obvious defects:
If the ISR function of UE before adhering to activates, then old SGSN and old MME all are registered on the HSS.If be in the unexpected power down of UE or its GSM subscriber identity module (SIM of idle condition, GSM Subscriber Identity Module)/universal subscriber identity module (USIM, UniversalSubscriber Identity Module) card is pulled out, then UE can not carry out explicit attachment removal process, and old SGSN and old MME think still that in a period of time this UE is in idle condition.Promptly if the implicit expression attachment removal timer (Implicit Detach Timer) of network side overtime before, UE starts shooting again and initiates attaching process, and the MME that this UE latest requests is adhered to adhere to before serve this UE old MME when being same MME, because this MME still remains with the context of this UE, executive condition according to step 8, then this MME will not send to HSS and upgrade location request message, cause HSS not send cancel location message to old SGSN, SGSN can not send the deleting bearing request message to Serving GW.Even new MME finds UE and still has not deleted EPS carrying, carried out step 7, it is new MME initiates process from deletion EPS carrying to Serving GW, but Serving GW this moment only is the ISR function deexcitation with this UE, and can not send the deleting bearing request message to PDN GW, the EPS that distributed for this UE before old SGSN, Serving GW and the PDN GW in the network still remained with UE and adhered to this moment carries, the Internet resources of this moment not by fully, deletion in time, cause utilization rate of network resource to reduce, and reduced the capacity and the reliability of network.

Embodiment
The embodiment of the invention provides a kind of delet method and system of EPS carrying, with so that the network side EPS that in time deletion is invalid carries, improves network resource utilization, thereby improves the capacity and the reliability of network.
A kind of scheme of the embodiment of the invention not deleted invalid Internet resources before proposing to delete in the Attach process, so-called Internet resources specifically are meant the EPS bearing resource that distributes into UE.User mobile control management entity described in the embodiment of the invention (UEMCME) is meant MME or SGSN.
Below in conjunction with accompanying drawing the technical scheme that the embodiment of the invention provides is described.
Referring to Fig. 2, the delet method of a kind of EPS carrying that the embodiment of the invention provides totally comprises step:
S101, first user mobile control management entity receive attach request of user equipment.
S102, determine this subscriber equipment according to the context of this subscriber equipment of self storage when first user mobile control management entity the ISR Function Identification when activating, first user mobile control management entity triggers self and second user mobile control management entity and initiates the process that the EPS of this subscriber equipment of deletion carries; Wherein, the user mobile control management entity of another wireless access type of when the ISR function activation, being registered to for this subscriber equipment of described second user mobile control management entity.
Store customer equipment context in the user mobile control management entity, when the ISR of subscriber equipment function activation, serve in the user mobile control management entity of this subscriber equipment the sign (being the IP address) that can another 3GPP of record inserts pairing user mobile control management entity, thereby sign and the corresponding ISR Function Identification of this subscriber equipment are for activating, otherwise, can not write down the sign that another 3GPP inserts pairing user mobile control management entity, be deexcitation thereby identify the corresponding ISR Function Identification of this subscriber equipment.
Have only when subscriber equipment is in not registered state, this subscriber equipment just can be initiated attaching process, therefore, if user mobile control management entity receives attach request of user equipment, by check self the storage with the corresponding mobile management of this subscriber equipment (MM) context, the ISR Function Identification of determining this subscriber equipment is for activating.Because MM Context is the part in the customer equipment context, so user mobile control management entity determines that according to the customer equipment context of self storing the ISR function of subscriber equipment is for activating.If this user mobile control management entity finds that according to the customer equipment context of self storage network side is the EPS bearing resource of this user equipment allocation before existing, determine that then this subnetwork resource is invalid resource, need deleted.
Particularly, can not delete the Internet resources (being invalid Internet resources) that are suspended in the network in time, fully, effectively at network side in the prior art, provide the two kinds of concrete schemes that can in attaching process, delete invalid Internet resources in time, effectively in embodiments of the present invention.
First kind of scheme: the request of adhering to that receives UE when user mobile control management entity, and the ISR Function Identification of determining this subscriber equipment according to the customer equipment context of self storage is when activating, and then this user mobile control management entity sends renewal position requests (Update Location Request) message to HSS.
Second kind of scheme: the request of adhering to that receives UE when user mobile control management entity, and the ISR Function Identification of determining this subscriber equipment according to the customer equipment context of self storage is when activating, then this user mobile control management entity sends attachment removal indication (Detach Indication) message, the process of indicating this another user mobile control management entity also to initiate to delete Internet resources to another user mobile control management entity of association (i.e. the user mobile control management entity of another wireless access type of being registered to of this UE) when ISR activates.
At first specifically introduce first kind of scheme.
The attaching process that first kind of scheme utilization defined at present can be realized the deletion to the Internet resources that are suspended in the network well, need not increases any step to attaching process shown in Figure 1, the step 8 that only needs to revise wherein gets final product, therefore realization is simple, and can realize the state synchronized between MME, SGSN, Serving GW and the HSS well.
As shown in Figure 1, the attaching process of a kind of UE that provides in the embodiment of the invention comprises:
UE initiates to adhere to the process that request and network obtain the IMSI sign of UE among the step 1-4.After evolved base station (eNodeB) was received Radio Resource control (RRC) message of UE, the load condition of topological sum MME Network Based was that UE selects new MME.If UE is attached to different MME, promptly new MME is different with last MME for this UE service, then needs to obtain for the MME of this UE service from the last time EPS carrying style of writing of this UE.
In the embodiment of the invention, abbreviate the current MME that adheres to of UE as new MME, abbreviate the last time as old MME for the MME that this UE serves; In like manner, can abbreviate the current SGSN that adheres to of UE as new SGSN, abbreviate the last time as old SGSN for the SGSN that this UE serves.
Step 5a is authentication and security processes, comprises Non-Access Stratum (NAS, Non-Access Stratum) security processes.In step 5b, need new MME that the mobile terminal identification of receiving in the Attach process (ME Identity) is sent to equipment identity register (EIR, Equipment Identity Register), the legitimacy of UE is done authentication.
Step 6 is to select transmission sign (CipheredOptions Transfer Flag) if carried in the Attach request message to encrypt, encrypt the new MME in back to UE acquisition request protocol configuration option (PCO, protocol Configuration Options) information or APN (APN) information in network activation.
The effect of step 7 is when new MME and old MME are same MME, and new MME removed before UE adheres to that also not deleted EPS carries in the network.
Step 8-11 is the updating location information process, i.e. the old MME identification information that HSS deletion is stored, and add new MME identification information, promptly new MME is registered among the HSS as current mobile control and management entity node for the UE service.
In the prior art, step 8 being described as in TS23.401: " If the MME has changedsince the last detach; or if there is no valid subscription context for the UE in theMME; or if the ME identity has changed; or if the UE provides an IMSI or the UEprovides an old GUTI which doesn ' t refer to a valid context in the MME; the MMEsends an Update Location Request (MME Identity; IMSI, ME Identity, MMECapabilities, Update Type) message to the HSS.The MME capabilities indicate theMME ' s support for regional access restrictions functionality.Update Type indicatesthis is Attach procedure. "; even the MME that adheres to is different the MME that newly adheres to of UE and UE last time; or do not have the effectively signatory context of UE in MME; or change has taken place portable terminal (ME) sign; or UE provides IMSI; or old global unique (user) temporary mark (GUIT) that UE provided can not be corresponding to an effective context among the new MME, then this new MME will send to HSS and upgrade position requests (Update Location Request) message, comprising MME sign (MME Identity), IMSI, ME Identity, MME ability (MME Capabilities) and updating type information such as (Update Type), the ability of new MME indicates new MME support area to insert limitation function, and it is an attaching process that Update Type indicates this.
And in the embodiment of the invention description of step 8 is revised as: " Ifthe MME has changed sincethe last detach; or if there is no valid subscription context for the UE in the MME; or if the ME identity has changed; or if the UE provides an IMSI or the UE providesan old GUTI which doesn ' t refer to a valid context in the MME; or the same MMEis used since last registered and the ISR function is already activated in the MME; the MME sends an Update Location Request (MME Identity, IMSI, ME Identity, MME Capabilities, Update Type) message to the HSS.The MME capabilitiesindicate the MME ' s support for regional access restrictions functionality.UpdateType indicates this is Attach procedure. "; that is to say; even the MME that adheres to is different the MME that newly adheres to of UE and this UE last time; or in MME, do not have the effectively signatory context of UE; or change has taken place in portable terminal (ME; Mobile Equipment) sign, or UE provides IMSI, or old global unique (user) temporary mark (GUIT) that UE provided can not be corresponding to an effective context among the new MME, or the MME that the current new MME that adheres to of UE and this UE last time adhere to is same MME, and when this UE still is identified as the ISR function activation, then this new MME will send to HSS and upgrade position requests (Update Location Request) message, comprising MMEIdentity, IMSI, ME Identity, information such as MME Capabilities and Update Type, the ability of new MME indicates new MME support area to insert limitation function, and it is an attaching process that Update Type indicates this.
In the step 9, HSS sends canceling position (Cancel Location) message to old MME, comprising IMSI and cancellation type indication (Cancellation Type) information.Old MME responds canceling position affirmation (Cancel Location Ack) message to HSS and represents to confirm, comprising IMSI information.Simultaneously old MME deletion and the corresponding mobile management of this UE (MM) context and EPS bearer context.If updating type indication is the Attach process, and HSS has the log-on message of SGSN, and then HSS also will send Cancel Location message to old SGSN, wherein comprises IMSI and Cancellation Type information.
In the step 10, old MME carries out the EPS deleting load-bearing process relevant with this UE with old SGSN.
Step 12-16 is the process that default EPS bearing (Default EPS Bearer) is set up, and this process is to be attached to the carrying that the UE of network sets up an acquiescence, and the connection of always online (always on) is provided.
Step 17-20 is that air interface connects the process of setting up/adhere to acceptance (Attach accept), in the transport process of Attachaccept message, also can indicate the information that whether needs to set up dedicated bearer.If carry then can set up two kinds of carryings simultaneously by the parallel mode of setting up default bearing (default bearer) and dedicated bearer (dedicated bearer).In this process, the address of gateway and Tunnel End Point Identifier (TEID, Tunnel End Point Identifier) also are carried to eNodeB by signaling, are used to set up up path; The address of eNodeB and TEID send to MME by the 20th step, are used to set up downlink path.
Step 21 and 22 is that UE returns and adheres to the process of finishing (Attach Complete) message, and after this process was finished, UE just can send upstream data.
Step 23 and 24 is the address information of MME notification service gateway about the user plane path, sets up the user plane path of down direction for UE.
And step 25 and 26 is under the situation that is used for switching between 3GPP and the non-3GPP (non-3GPP), when UE when the non-3GPP network enters the 3GPP network, carry out type and adhere to (HandoverAttach) process for switching, if the PDN GW address that PDN GW that selects and HSS indicate in subscription data is not simultaneously, new MME need give HSS with this APN and PDN GW address notification, revises the content of HSS subscription data.
Need to prove that above-mentioned steps 1 is to step 7, and step 9 is consistent with the corresponding steps of TS23.401v8.4.1 defined to step 26.
Following mask body is introduced second kind of scheme.
Second kind of scheme need increase several message to existing Attach process, and specifically referring to Fig. 3, a kind of Attach process that the embodiment of the invention provides comprises:
Step 1 to 6 is consistent with the step of TS23.401v8.4.1 defined, and is promptly consistent to step 6 with step 1 shown in Figure 1.
Step 7a: new MME sends deleting bearing request (Delete Bearer Request) message and gives ServingGW, comprising TEID and dismounting indication (Teardown indication) information, Teardown Indication is used to indicate the PDN at the whole TEID of deletion place to connect.If PDN GW needs the positional information of UE, then MME also need further add the positional information of UE in this message.
Step 7b: when Serving GW receives first deleting bearing request (the Delete Bearer Request) message that comes from new MME or SGSN under the state of the ISR of UE function activation, the ISR Function Identification that Serving GW is provided with this UE that self stores is deexcitation, and the EPS bearer context information of deletion and new MME or corresponding this UE of SGSN, reply deleting bearing response (Delete BearerResponse) message then and give new MME.
When if Serving GW receives deleting bearing request (the Delete Bearer Request) message that comes from new MME or SGSN under the state of the ISR of UE function deexcitation, the EPS bearer context information of Serving GW deletion and new MME or corresponding this UE of SGSN then, the 7e of redirect execution in step then, promptly send deleting bearing request (Delete Bearer Request) message to PDN GW, comprising TEID and Teardown indication information, receive that at Serving GW PDN GW is after deleting bearing response (Delete Bearer Response) message that step 7f replys, Serving GW responds deleting bearing response (Delete Bearer Response) message, i.e. execution in step 7h to new MME or SGSN.
Step 7c: if the ISR Function Identification of UE is for activating, then MME sends attachment removal indication (DetachIndication) message and gives related SGSN, comprises IMSI and reason (Cause) parameter value in this message.It is local attachment removal (Local Detach) or complete attachment removal (CompleteDetach) that the Cause parameter is used for indication.
In the embodiment of the invention, the Cause parameter value is complete attachment removal (Complete Detach).
Step 7d: if the Cause parameter in the Detach Indication message of step 7c is CompleteDetach, then SGSN sends deleting bearing request (Delete Bearer Request) message to Serving GW, if PDN GW needs the positional information of UE, then SGSN need carry the positional information of UE in this message.
If Cause is Local Detach, then the ISR function of this UE of SGSN deexcitation directly enters step 7i, and the carrying between Serving GW and the PDN GW will exist in this case, and then execution in step 7e does not arrive step 7h.
Because the Cause parameter value in the embodiment of the invention is Complete Detach, then step 7e all will carry out to step 7h.
Step 7e: if the ISR Function Identification of the UE that stores among the Serving GW is for activating, then the ISR Function Identification of this UE is set is deexcitation to Serving GW.
If the ISR Function Identification of the UE that stores among the Serving GW is deexcitation, then Serving GW sends deleting bearing request (Delete Bearer Request) message to PDN GW, wherein comprises TEID and Teardown indication.Teardown indication indication discharges and belongs to all EPS carryings that this PDN connects.If the ISR Function Identification of the UE that stores among the Serving GW is deexcitation, then step 7e is triggered by step 7a.If the positional information of UE is provided in MME or the request message of SGSN at deleting bearing, then in this step 7e, comprise the positional information of UE in step 7a or step 7d.
Step 7f:PDN GW sends deleting bearing response (Delete BearerResponse) message to Serving GW, wherein comprises TEID; In this process, PDN GW has deleted all carryings under the PDN connection.
Step 7g: if strategy and charging rule functions (PCRF, Policy and Charging RulesFunction) is used, then PDN GW carries out IP connection net conversation end (IP-CAN SessionTermination) process, and this process defines in TS23.203.PDN GW is deleted to the EPS carrying of PCRF entity indication UE in this process.
Step 7h:Serving GW responds deleting bearing response (Delete Bearer Response) message to SGSN, comprising TEID information.
Step 7i:SGSN responds the attachment removal indication to MME and confirms (Detach IndicationAcknowledge) message.
Because when new MME finds to have in the network not deleted invalid Internet resources, can initiate to delete the process of Internet resources at step 7a, trigger the process that SGSN also initiates to delete Internet resources by step 7c simultaneously, receive the request (being two requests of step 7a and step 7d) of two deletion Internet resources as Serving GW, then carry out the deleting load-bearing process (being step 7e, step 7f and step 7g) under the PDN connection, make that the not deleted invalid Internet resources of network side are deleted fully.
Step 8 is consistent with the step of TS23.401v8.4.1 defined to step 26, and promptly the step 8 with shown in Figure 1 is consistent to step 26.
Above-mentioned is to be that MME is the explanation that example is carried out with the up-to-date user mobility control and management entity that adheres to of UE, in like manner, is the situation of SGSN for the up-to-date user mobility control and management entity that adheres to of UE, and the technical scheme that the embodiment of the invention provides is suitable equally.
