Description

A kind of switching handling method, equipment and system
Technical field
The present invention relates to wireless communication technology field, particularly relate to a kind of switching handling method, equipment and system.
Background technology
At 3GPP(the3rdGenerationPartnershipProject, third generation partner program) in 23401 agreements, work as UE(UserEquipment, subscriber equipment) position or access style be when changing, and can trigger switching flow.When there being part to carry handoff failure in handoff procedure, current core-network side MME(MobilityManagementEntity, mobile management entity) need triggering two flow processs to complete whole handoff procedure:
1, MME triggers amendment carrying request (ModifyBearerRequest) message, notice SGW(ServingGateway, gateway)/PGW(PDN(PacketDataNetwork, packet data network) Gateway, PDN Gateway) beared information of current positional information, access style and the successful switch of UE.
2, MME triggers deleting load-bearing message, and notice SGW/PGW deletes the carrying of handoff failure.
Therefore, between whole handoff procedure network side element, flow process is mutual comparatively complicated, SGW/PGW/PCRF(PolicyAndChargingRulesFunction, "Policy and Charging Rules Function entity) network element internal process needs to safeguard handoff failure bearing resource and state machine, and PCRF may issue new rule because UE positional information changes in amendment carrying request process, such as have modified QoS(QualityofService, service quality) information or carrying bandwidth etc., between above-mentioned like this flow process 1 and 2, PGW also may trigger load creating or more new technological process.
Below in conjunction with accompanying drawing, existing switching flow is described in detail.
In 23401 agreements, the immovable switching flow of SGW mainly comprises following several:
1), the immovable X2 of SGW switches;
2), the immovable S1 of SGW switches;
3), the immovable RAU(RouteAreaUpdate of SGW, routing region updating) flow process;
4), the immovable TAU(TrackingAreaUpdate of SGW, tracking area update) flow process.
In these flow processs, MME completes handoff procedure by sending amendment bearing request message notice SGW.For the immovable X2 switching flow of SGW, see Fig. 1, can comprise:
1, there is eNB(base station in UE) inner switching.
2, target eNB sends paths convert requests (PathSwitchRequest) message to MME, notice MMEUE changes community, and this message comprises the carrying list of the Cell Global Identification of Target cell, the carrying list of handover success and handoff failure.
3, each PDN that MME accepts for target eNB connects, and send an amendment bearing request message to SGW, this message comprises the user face data (comprising eNB address and tunnel number, Teidu(user face) of the carrying of handover success).Wherein, if the positional information change that PGW requests UE reports, then MME also can carry the positional information of UE within the message.MME comprises the unacceptable dedicated bearer of target eNB in the carrying list of handoff failure, after switching completes, discharge unacceptable dedicated bearer by carrying dispose procedure.
If 4 SGW receive the UE positional information of change, and the positional information change that PGW requests UE reports, then the positional information of this UE is informed to PGW by amendment carrying request by SGW.This message comprises SGW address and Teid(comprises Teidu and Teidc(chain of command tunnel number)), and the positional information of UE.PGW returns amendment carrying response (ModifyBearerResponse) message to SGW.Correspondingly, SGW replys amendment bearing response message to MME.
5, MME confirms (PathSwitchRequestAck) message to target eNB reverse-path convert requests.If some carryings do not have successful switch in the core network, MME must indicate the carrying of failing to set up in path integration request acknowledge message, has switched rear initiations carrying dispose procedure, discharges to fail the resources of core network of carrying correspondence of foundation.Target eNB must delete the context of carrying that notified core net fails to set up.Target eNB sends releasing resource message to source eNB, notification source eNB handover success, and triggers resource release.
6, comprise the carrying of handover success and the carrying of handoff failure in path switching request information, MME needs the load bearing deactivation of handoff failure (initiating load bearing deactivation process to the carrying of handoff failure).If certain PDN connects need release, then MME initiates PDN Connection Release process.If all PDN connect all need release, then MME initiates attachment removal flow process.
Wherein: MME can comprise the idiographic flow that load bearing deactivation is initiated in the carrying of handoff failure:
If the part carrying be carried as in PDN connection of handoff failure, then in handoff procedure, MME needs to send deleting bearing order (DeleteBearerCommand) message to SGW, notice SGW needs the bearing resource of the handoff failure deleted, after SGW receives message, notice PGW deletes the bearing resource of handoff failure, after PGW receives message, deleting bearing request (DeleteBearerRequest) message is returned to SGW, SGW sends out deleting bearing request message to MME according to the information of deleting resource in this message after receiving message again, MME deletes the bearing resource of the inner handoff failure preserved after receiving message, deleting bearing response (Deletebearerresponse) message is sent to SGW after MME processes, SGW deletes the beared information of the inner handoff failure preserved after receiving message, reply deleting bearing response message again to PGW, PGW deletes the bearing resource information of the inner handoff failure preserved after receiving message.
Inventor is realizing in process of the present invention, finds that prior art at least exists following defect:
Switching flow realizes deletion two flow processs needing the foundation of the carrying of handover success and the carrying of handoff failure, EPC(EvolvedPacketCore, evolution data packet-based core networks) Signalling exchange is frequent between network MME, SGW, PGW and PCRF network element, and processing messages flow process is complicated.
In addition, before the deletion flow process of the carrying of handoff failure, SGW, PGW and PCRF inside not only needs to safeguard successful switching carrier resource and state machine, also will safeguard bearing resource and the state machine of handoff failure, add machine utilization.Meanwhile, in the deletion flow process of the carrying of handoff failure, between network element, Signalling exchange is frequent, if there is packet loss may cause the situation that between network element, resource is inconsistent.

It should be noted that in embodiments of the present invention, the first amendment bearing request message is not refer in particular to certain specifically to revise bearing request message, but refers to the amendment bearing request message that MME sends to SGW; Correspondingly, second amendment bearing request message refers to the amendment bearing request message that SGW sends to PGW, first amendment bearing response message refers to the amendment bearing response message that PGW returns to SGW, and the second amendment bearing response message refers to the amendment bearing response message that SGW returns to MME.
Below in conjunction with the accompanying drawing in the application, carry out clear, complete description to the technical scheme in the application, obviously, described embodiment is a part of embodiment of the application, instead of whole embodiments.Based on the embodiment in the application, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of the application's protection.
As shown in Figure 2, be the schematic flow sheet of a kind of switching handling method that the embodiment of the present invention provides, can comprise the following steps:
Step 201, SGW receive the first amendment bearing request message that MME sends, and carry the carrying list of handover success and the carrying list of handoff failure in this first amendment bearing request message.
Concrete, when SGW immovable switching occurs in EPC network (switching to example to be described with the immovable X2 of SGW), target eNB can to MME transmit path transition request message, to notify that MMEUE there occurs cell merge.Wherein, the carrying list of handover success and the carrying list of handoff failure is carried in this path switching request information.
After MME receives the path switching request information of target eNB transmission, can connect for each PDN of target eNB acceptance and send one first amendment bearing request message to SGW, in this first amendment bearing request message, carry the carrying list of handover success and the carrying list of handoff failure.
Step 202, SGW send the second amendment bearing request message according to this first amendment bearing request message to PGW, carry the carrying list of handover success and the carrying list of handoff failure in this second amendment bearing request message.
Concrete, after SGW receives the first amendment bearing request message of MME transmission, according to the carrying Resources allocation (as Teidu) that the carrying list of the handover success carried in this first amendment bearing request message is handover success, to set up corresponding tunnel to PGW, and the carrying list of handover success of carrying in first this amendment bearing request message and the carrying list of handoff failure are carried in the second amendment bearing request message simultaneously, send to PGW.
Step 203, PGW receive the second amendment bearing request message that SGW sends, and after switching accordingly according to the carrying list of the handover success carried in this second amendment bearing request message, the first amendment bearing response message is returned to SGW, and the carrying that the carrying list of deleting the handoff failure carried in this second amendment bearing request message is corresponding.
Concrete, PGW receives the second amendment bearing request message that SGW sends, and carries the carrying list of handover success and the carrying list of handoff failure in this second amendment bearing request message simultaneously.PGW carries out corresponding hand-off process (namely carrying out UE positional information or/and the renewal of the information such as SGW positional information according to bearer context information) according to this second amendment bearing request message, and after hand-off process completes, the first amendment bearing response message is returned to SGW, after this, PGW deletes carrying corresponding to the carrying list of handoff failure of carrying in the second amendment bearing request message.
Wherein, carry the carrying list of handover success and the carrying list of handoff failure in the first amendment bearing response message that PGW returns to SGW, carry in bearing request message consistent is revised in the carrying list of this handover success and the carrying list of handoff failure and PGW receives second.
In addition, PGW to SGW return first amendment bearing response message in also can carry the information whether PGW is successfully completed hand-off process, and the information whether hand-off process that in the carrying list of handover success, each carrying is corresponding is successfully completed, after SGW receives the first amendment bearing response message that PGW returns, can determine whether to carry out hand-off process according to the corresponding information carried in this first amendment bearing response message, and how hand-off process is carried out to each carrying in the carrying list of handover success, the specific implementation of this handling process (SGW is to the handling process of carrying each in the carrying list of handover success) can see the relevant treatment flow process in existing protocol, do not repeat them here.
Wherein, when being configured with dynamic PCC(PolicyControlandCharging in EPC network, strategy, control and charging) rule (namely EPC network internal has affixed one's name to PCRF), after then PGW receives the amendment bearing request message of SGW transmission, also need to report UE position to change to PCRF, upgrade UE positional information to make PCRF.Such as, PGW can pass through to send CCR(CreditControlRequest, credit control request to PCRF) message, as IP-CANsessionmod(Access Network session modification) message, notice PCRFUE position changes event.
Step 204, SGW receive the first amendment bearing response message that PGW returns, and after carrying out corresponding hand-off process, the second amendment bearing response message is returned to MME, and the carrying that the carrying list of deleting the handoff failure carried in this second amendment bearing response message is corresponding.
Concrete, after SGW receives the first amendment bearing response message (carrying the carrying list of handover success and the carrying list of handoff failure in this first amendment bearing response message) that PGW returns, corresponding hand-off process (namely carrying out UE updating location information etc. according to bearer context information) is carried out according to this first amendment bearing response message, and after switching completes, the second amendment bearing response message is returned to MME, after this, SGW deletes carrying corresponding to the carrying list of handoff failure of carrying in the first amendment bearing response message.
Wherein, SGW to MME return second amendment bearing response message in carry the carrying list of handover success and the carrying list of handoff failure.
Step 205, MME receive the second amendment bearing response message that SGW returns, and after switching accordingly according to the carrying list of the handover success carried in this second amendment bearing response message, delete the carrying that the carrying list of the handoff failure carried in this second amendment bearing response message is corresponding.
Concrete, after MME receives the second amendment bearing response message that SGW returns, carry out corresponding hand-off process (carrying out UE location updating etc. according to bearer context information), and after hand-off process completes, delete the carrying that the carrying list of the handoff failure carried in the second amendment bearing response message is corresponding.
Wherein, the Signalling exchange figure of hand-off process flow process that the embodiment of the present invention provides can see Fig. 3.
Further, when being deployed with PCRF in EPC network, and after PGW reports UE location updating event to PCRF, PCRF may issue new PCC rule (as upgraded due to UE positional information, PCRF may need to generate and issue new charging regulation).
In embodiments of the present invention, when new PCC rule (the PCC rule after renewal) that PGW receives that PCRF issues, PGW needs this new PCC rule of reprocessing after the carrying of deleting handoff failure, deletes to avoid the mistake carried.For this reason, PGW receives new PCC rule, first can determine whether the carrying of deleting handoff failure, if delete, then process this new PCC rule, if also do not delete, then can first by this new PCC rule cache, and after the carrying of deleting handoff failure, this new PCC rule of reprocessing.
By describing above and can finding out, the technical scheme that the embodiment of the present invention provides compared with prior art, at least comprises following beneficial effect:
1), reduce Signalling exchange, in simplification hand-off process flow process, handling process between network element, reduces machine utilization
In prior art, after MME receives path switching request information, send amendment bearing request message to SGW, in this amendment bearing request message, carry the carrying list of handover success and the carrying list of handoff failure.After SGW receives this amendment bearing request message, only the carrying request of handoff failure is carried in amendment bearing request message and sends to PGW.After the hand-off process of the carrying of all handover success completes, MME initiates deleting load-bearing flow process again, to delete the carrying of handoff failure.
And in the technical scheme that the embodiment of the present invention provides, the carrying list of the handover success carried in this first amendment bearing request message and the carrying list of handoff failure, after receiving the first amendment bearing request message of MME transmission, are all carried to PGW by the second amendment bearing request message by SGW.After PGW completes hand-off process, in the first amendment bearing response message, also the carrying of handover success and the carrying of handoff failure are all carried to SGW, equally, SGW returns the second amendment bearing response message according to this first amendment bearing response message to MME more simultaneously.After MME, SGW, PGW complete hand-off process, separately inner carrying of deleting handoff failure, reduces the message interaction that deleting load-bearing flow process causes, and to simplify in hand-off process flow process handling process between network element, reduces machine utilization.
2) EPC network element resources is saved, Optimal State machine
In prior art, after hand-off process completes, SGW, PGW need to safeguard the carrying of handover success and the carrying of handoff failure, also will safeguard the state machine of all carryings simultaneously, result in the wasting of resources.
And in the technical scheme that the embodiment of the present invention provides, after EPC network element completes hand-off process, inner carrying of deleting handoff failure separately, without the need to safeguarding carrying and the state machine of handoff failure again, saves EPC network element internal resource, and simplify state machine maintenance.
3) for the scene deploying PCRF, the possibility of deleting load-bearing mistake is reduced
In prior art, in handoff process, or after hand-off process completes, PCRF may issue new PCC rule, PGW needs after receiving this PCC rule to trigger new handling process (more new bearer or establishment carrying), the carrying relevant to new handling process may comprise the carrying of handoff failure, in the handling process of follow-up deleting bearing, and may by this part deleting load-bearing.Such as, PCC rule QoS changes, and PGW bearing binding may upgrade certain carrying, but if this carrying is the carrying of handoff failure, this carrying finally can be deleted.
And in the technical scheme that the embodiment of the present invention provides, when PGW receives new PCC rule, PGW can after the carrying of deleting handoff failure, this new PCC rule of reprocessing, effectively reduces the possibility of wrong deleting bearing.
4) possibility that between EPC network element, resource is inconsistent, is reduced
In prior art, need after each network element completes hand-off process, initiate the flow process of the carrying of deleting handoff failure.The flow process of the carrying of existing deletion handoff failure does not need to judge whether opposite end network element successfully deletes the carrying of handoff failure, all needs the respective resources of deleting local terminal network element.Therefore, if opposite end network element response timeout (as lost message between network element), local terminal network element still deletes the bearing resource of handoff failure, then may cause the situation that resource is inconsistent.
And in embodiments of the present invention, the carrying of deleting handoff failure is completed by network element internal after hand-off process, and the hand-off process of network element needs to carry out after receiving the response message of opposite end (after SGW needs to receive the first amendment bearing response message that PGW returns, carry out hand-off process again, and after hand-off process completes, delete the carrying of handoff failure again), effectively can reduce the inconsistent possibility of resource between network element.
