According to the method, the equipment and the system, each of a second modify bearer request message transmitted from a serving gateway (SGW) to a packet data network gateway (PGW) and a first modify bearer response message returned from the PGW to the SGW simultaneously carries a list of successfully switched bearers and a list of bearers failed to be switched, and after finishing switching and returning the first modify bearer response message to the SGW, the PGW deletes the bearers corresponding to the list of bearers failed to be switched; after finishing switch and returning a second modify bearer response message to a mobility management entity (MME), the SGW deletes the bearers failed to be switched; and after finishing switching, the MME deletes the bearers corresponding to the list of bearers failed to be switched. Namely a flow of deleting the bearers failed to be switched is not required to be reinitiated among the MME, the SGW and the PGW after the switching is finished, so that a switching processing flow is simplified, an equipment load is lowered, and meanwhile, the condition of resource inconsistency between network elements is effectively avoided.
Description
Technical field
The present invention relates to wireless communication technology field, relate in particular to a kind of switching handling method, equipment and system.
Background technology
At 3GPP(the 3rd Generation Partnership Project, third generation partner program) in 23401 agreements, when UE(User Equipment, subscriber equipment) when position or access style change, can trigger switching flow.When part carrying handoff failure is arranged in the handoff procedure, present core-network side MME(Mobility Management Entity, mobile management entity) need to trigger two flow processs to finish whole handoff procedure:
1, MME triggers and revises carrying request (Modify Bearer Request) message, notice SGW(Serving Gateway, gateway)/PGW(PDN(Packet Data Network, packet data network) beared information of UE current position information, access style and successful switch Gateway, PDN Gateway).
2, MME triggers deleting load-bearing message, the carrying of notice SGW/PGW deletion handoff failure.
Therefore, flow process is comparatively complicated alternately between whole handoff procedure network side network element, SGW/PGW/PCRF(Policy And Charging Rules Function, the "Policy and Charging Rules Function entity) network element internal is handled and need be safeguarded handoff failure bearing resource and state machine, and PCRF may issue new rule because the UE positional information changes in revising the carrying request process, such as having revised QoS(Quality of Service, service quality) information or carrying bandwidth etc., PGW also may trigger load creating or new technological process more between the above-mentioned like this flow process 1 and 2.
Below in conjunction with accompanying drawing existing switching flow is described in detail.

2), the immovable S1 of SGW switches;
3), the immovable RAU(Route Area of SGW Update, routing region updating) flow process;
4), the immovable TAU(Tracking Area of SGW Update, tracking area update) flow process.
MME finishes handoff procedure by sending modification bearing request message notice SGW in these flow processs.Be example with the immovable X2 switching flow of SGW, referring to Fig. 1, can comprise:
1, the eNB(base station takes place in UE) the inner switching.
2, target eNB sends paths conversion request (Path Switch Request) message to MME, notice MME UE has changed the residential quarter, comprises the residential quarter overall identification of Target cell, the carrying tabulation of handover success and the carrying tabulation of handoff failure in this message.
3, MME connects at each bar PDN of target eNB acceptance, sends one to SGW and revises bearing request message, comprises the user face data (comprising eNB address and Teidu(user's face tunnel Taoist monastic name) of the carrying of handover success in this message).Wherein, report if PGW has asked the positional information of UE to change, then MME also can carry the positional information of UE in this message.MME comprises the unacceptable dedicated bearer of target eNB in the carrying tabulation of handoff failure, discharge unacceptable dedicated bearer by the carrying dispose procedure after switching is finished.
If 4 SGW receive the UE positional information of change, and PGW asked the positional information of UE to change to report, and then SGW is notified to PGW with the positional information of this UE by revising the carrying request.Comprise in this message that SGW address and Teid(comprise Teidu and Teidc(chain of command tunnel Taoist monastic name)), and the positional information of UE.PGW returns to SGW and revises carrying response (Modify Bearer Response) message.Correspondingly, SGW replys to MME and revises bearing response message.
5, MME confirms (Path Switch Request Ack) message for target eNB reverse-path conversion request.If some are carried on and do not have successful switch in the core net, MME must indicate the carrying of failing to set up in path conversion request acknowledge message, initiate the carrying dispose procedure after switching is finished, and discharges the resources of core network of the carrying correspondence of failing to set up.Target eNB must be deleted the context of the carrying that notified core net fails to set up.Target eNB sends the release message related to resources for source eNB, notification source eNB handover success, and trigger resource release.
6, comprise the carrying of handover success and the carrying of handoff failure in the path switching request information, MME need be with the load bearing deactivation (the load bearing deactivation process is initiated in the carrying to handoff failure) of handoff failure.Need to discharge if certain PDN connects, then MME initiates PDN connection dispose procedure.All need to discharge if all PDN connect, then MME initiates the attachment removal flow process.
Wherein: the idiographic flow that load bearing deactivation is initiated in the carrying of the handoff failure of MME can comprise:
If the part that is carried as in the PDN connection of handoff failure is carried, then MME need send deleting bearing order (Delete Bearer Command) message to SGW in the handoff procedure, the bearing resource of the handoff failure that notice SGW need delete, after SGW receives message, the bearing resource of notice PGW deletion handoff failure, after PGW receives message, return deleting bearing request (Delete Bearer Request) message to SGW, SGW sends out the deleting bearing request message to MME according to the information of deletion resource in this message after receiving message again, MME receives the bearing resource of the inner handoff failure of preserving of deletion after the message, MME handles the back and sends deleting bearing response (Delete bearer response) message to SGW, SGW receives the beared information of the inner handoff failure of preserving of deletion after the message, reply the deleting bearing response message again and give PGW, PGW receives the bearing resource information of deleting the inner handoff failure of preserving after the message.
The inventor finds that there is following defective at least in prior art in realizing process of the present invention:
Switching flow to need to realize two flow processs of deletion of the carrying of the foundation of carrying of handover success and handoff failure, EPC(Evolved Packet Core, the evolution data packet-based core networks) Signalling exchange is frequent between network MME, SGW, PGW and the PCRF network element, processing messages flow process complexity.
In addition, before the deletion flow process of the carrying of handoff failure, SGW, PGW and PCRF inside not only need to safeguard successful switching carrier resource and state machine, also will safeguard bearing resource and the state machine of handoff failure, have increased machine utilization.Simultaneously, in the deletion flow process of the carrying of handoff failure, Signalling exchange is frequent between network element, may cause the inconsistent situation of resource between network element if packet loss takes place.

Embodiment
At the defective of above-mentioned prior art, the embodiment of the invention provides a kind of technical scheme of hand-off process, is applied to the immovable switching flow of SGW.In this technical scheme, when SGW receives first when the revising carrying request (Modify Bearer Request) message of carrying tabulation of the carrying tabulation that carries handover success that MME sends and handoff failure, this SGW is carried at second simultaneously with the carrying tabulation of the carrying tabulation of this handover success and handoff failure and revises in the bearing request message and send to PGW, so that PGW switches accordingly according to the carrying of this handover success tabulation, and finishing after, switching returns first the revising carrying and respond (Modify Bearer Response) message of carrying tabulation of the carrying tabulation of carrying this handover success and handoff failure to SGW; When SGW receive that PGW returns first revise bearing response message after, carrying tabulation according to handover success is switched accordingly, and return to MME the carrying tabulation of carrying this handover success and handoff failure the carrying tabulation second revise bearing response message so that MME switches accordingly according to the carrying tabulation of this handover success.
Wherein, PGW finish switch and to SGW return revise first bearing response message after, the corresponding carrying of carrying tabulation of deletion handoff failure; SGW finish switch and to MME return second revise bearing response message after, the carrying of deletion handoff failure correspondence; After MME finishes switching, the corresponding carrying of carrying tabulation of deletion handoff failure, namely in embodiments of the present invention, need be after switching not be finished between MME, SGW and the PGW, again initiate the deletion flow process of the carrying of handoff failure, simplified the hand-off process flow process, reduced machine utilization, simultaneously also effectively avoided the inconsistent situation of resource between network element.
It should be noted that in embodiments of the present invention the first modification bearing request message is not to refer in particular to certain specific modification bearing request message, but refers to the modification bearing request message that MME sends to SGW; Correspondingly, second revises bearing request message refers to the modification bearing request message that SGW sends to PGW, first revises bearing response message refers to the modification bearing response message that PGW returns to SGW, and second revises bearing response message refers to the modification bearing response message that SGW returns to MME.
Below in conjunction with the accompanying drawing among the application, the technical scheme among the application is carried out clear, complete description, obviously, described embodiment is a part of embodiment of the application, rather than whole embodiment.Based on the embodiment among the application, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work belongs to the scope that the application protects.
As shown in Figure 2, the schematic flow sheet of a kind of switching handling method that provides for the embodiment of the invention can may further comprise the steps:
Step 201, SGW receive the first modification bearing request message that MME sends, and carry the carrying tabulation of handover success and the carrying tabulation of handoff failure in this first modification bearing request message.
Concrete, when in the EPC network the immovable switching of SGW taking place (switching to example with the immovable X2 of SGW is described), the residential quarter switching can take place with notice MME UE to MME transmit path conversion request message in target eNB.Wherein, carry the carrying tabulation of handover success and the carrying tabulation of handoff failure in this path switching request information.
After MME receives the path switching request information of target eNB transmission, can connect at each bar PDN that target eNB is accepted to one first of SGW transmission and revise bearing request message, carry the carrying tabulation of handover success and the carrying tabulation of handoff failure in this first modification bearing request message.
Step 202, SGW send second according to this first modification bearing request message to PGW and revise bearing request message, carry the carrying tabulation of handover success and the carrying tabulation of handoff failure in this second modification bearing request message.
Concrete, after SGW receives the first modification bearing request message of MME transmission, be the carrying Resources allocation (as Teidu) of handover success according to this first carrying tabulation of revising the handover success that carries in the bearing request message, to set up corresponding tunnel with PGW, and the carrying tabulation of the carrying tabulation of the handover success that carries in first this modification bearing request message and handoff failure is carried at second simultaneously revises in the bearing request message, send to PGW.
Step 203, PGW receive the second modification bearing request message that SGW sends, and after switching accordingly according to this second carrying tabulation of revising the handover success that carries in the bearing request message, return first to SGW and revise bearing response message, and delete the corresponding carrying of carrying tabulation of the handoff failure that carries in this second modification bearing request message.
Concrete, PGW receives the second modification bearing request message that SGW sends, and carries the carrying tabulation of handover success and the carrying tabulation of handoff failure in this second modification bearing request message simultaneously.PGW carries out corresponding hand-off process (namely carrying out the UE positional information or/and the renewal of information such as SGW positional information according to bearer context information) according to this second modification bearing request message, and after hand-off process is finished, return first to SGW and revise bearing response message, after this, the corresponding carrying of carrying tabulation of the handoff failure that carries in the bearing request message is revised in PGW deletion second.
Wherein, PGW first revises the carrying tabulation that carries handover success in the bearing response message and the carrying tabulation of handoff failure to what SGW returned, and that carries in the carrying tabulation of this handover success and the carrying of handoff failure tabulation and the second modification bearing request message that PGW receives is consistent.
In addition, PGW first revises in the bearing response message and also can carry the information whether PGW completes successfully hand-off process to what SGW returned, and the information that whether the corresponding hand-off process of each carrying completes successfully in the carrying of the handover success tabulation, SGW receive that PGW returns first revise bearing response message after, can determine whether to carry out hand-off process according to the corresponding information that carries in this first modification bearing response message, and how each carrying in the carrying of the handover success tabulation to be carried out hand-off process, the specific implementation of this handling process (handling process of each carrying in the carrying tabulation of the handover success of SGW) can not repeat them here referring to the relevant treatment flow process in the existing protocol.
Wherein, in the EPC network, disposed dynamic PCC(Policy Control and Charging, strategy, control and charging) rule (being that the EPC network internal has been affixed one's name to PCRF), after then PGW receives the modification bearing request message of SGW transmission, also need to report the UE position to change to PCRF, so that PCRF upgrades the UE positional information.For example, PGW can be by sending CCR(Credit Control Request to PCRF, and credit control is asked) message, as IP-CAN session mod(Access Network session modification) message, notice PCRF UE position changes event.
Step 204, SGW receive the first modification bearing response message that PGW returns, and after carrying out corresponding hand-off process, return second to MME and revise bearing response message, and delete the corresponding carrying of carrying tabulation of the handoff failure that carries in this second modification bearing response message.
Concrete, what SGW received that PGW returns first revises bearing response message (this first revise the carrying tabulation that carries handover success in bearing response message and the carrying tabulation of handoff failure) afterwards, carry out corresponding hand-off process (namely carrying out UE updating location information etc. according to bearer context information) according to this first modification bearing response message, and after switching is finished, return second to MME and revise bearing response message, after this, the corresponding carrying of carrying tabulation of the handoff failure that carries in the bearing response message is revised in SGW deletion first.
Wherein, SGW second revises the carrying tabulation that carries handover success in the bearing response message and the carrying tabulation of handoff failure to what MME returned.
Step 205, MME receive the second modification bearing response message that SGW returns, and after switching accordingly according to this second carrying tabulation of revising the handover success that carries in the bearing response message, the corresponding carrying of carrying tabulation of deleting the handoff failure that carries in this second modification bearing response message.
Concrete, MME receive that SGW returns second revise bearing response message after, carry out corresponding hand-off process (carrying out UE position renewal etc. according to bearer context information), and after hand-off process was finished, the corresponding carrying of carrying tabulation of the handoff failure that carries in the bearing response message was revised in deletion second.
Wherein, the Signalling exchange figure of the hand-off process flow process that provides of the embodiment of the invention can be referring to Fig. 3.
Further, be deployed with PCRF in the EPC network, and after PGW reports UE position update event to PCRF, PCRF may issue new PCC rule (as because the UE positional information is upgraded, PCRF may need to generate and issue new charging regulation).
In embodiments of the present invention, when PGW received the new PCC rule (the PCC rule after the renewal) that PCRF issues, PGW need handle this new PCC rule again after the carrying of deletion handoff failure, with the mistake deletion of avoiding carrying.For this reason, PGW receives new PCC rule, can determine whether to delete the carrying of handoff failure earlier, if delete, then handle this new PCC rule, if also not deletion, then can be earlier that this is new PCC rule buffer memory, and after the carrying of deletion handoff failure, handle this new PCC rule again.
By above description as can be seen, the technical scheme that the embodiment of the invention provides compared with prior art comprises following beneficial effect at least:
1), reduces Signalling exchange, handling process between the network element in the simplification hand-off process flow process, reduction machine utilization
In the prior art, after MME receives path switching request information, send the modification bearing request message to SGW, carry the carrying tabulation of handover success and the carrying tabulation of handoff failure in this modification bearing request message.After SGW receives this modification bearing request message, only the carrying request of handoff failure is carried at revise in the bearing request message and sends to PGW.After the hand-off process of the carrying of all handover success was finished, MME initiated the deleting load-bearing flow process again, with the carrying of deletion handoff failure.
And in the technical scheme that the embodiment of the invention provides, SGW receive that MME sends first revise bearing request message after, this first carrying tabulation of revising the carrying tabulation of the handover success that carries in bearing request message and handoff failure is all revised bearing request message by second carries to PGW.After PGW finishes hand-off process, also simultaneously the carrying of handover success and the carrying of handoff failure are all carried to SGW in the first modification bearing response message, same, SGW returns second according to this first modification bearing response message to MME again and revises bearing response message.After MME, SGW, PGW finished hand-off process, the carrying of inner deletion handoff failure reduced the message interaction that the deleting load-bearing flow process causes separately, had simplified in the hand-off process flow process handling process between the network element, had reduced machine utilization.
2) save the EPC network element resources, optimize state machine
In the prior art, after hand-off process was finished, SGW, PGW need safeguard the carrying of handover success and the carrying of handoff failure, also will safeguard the state machine of all carryings simultaneously, had caused the wasting of resources.
And in the technical scheme that the embodiment of the invention provides, after the EPC network element was finished hand-off process, the carrying of handoff failure was deleted in inside separately, need not to safeguard carrying and the state machine of handoff failure again, saved EPC network element internal resource, and had simplified the state machine maintenance.
3) for the scene of having disposed PCRF, reduced the possibility of deleting load-bearing mistake
In the prior art, in handoff process, after perhaps hand-off process is finished, PCRF may issue new PCC rule, PGW needs to trigger new handling process (more new bearer or establishment carrying) after receiving this PCC rule, the carrying relevant with new handling process may comprise the carrying of handoff failure, in the handling process of follow-up deleting bearing, and may be with this part deleting load-bearing.For example, PCC rule QoS changes, and the 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 invention provides, when PGW received new PCC rule, PGW can handle this new PCC rule again after the carrying of deletion handoff failure, had effectively reduced the possibility of wrong deleting bearing.
4), reduced the inconsistent possibility of resource between the EPC network element
In the prior art, need after finishing hand-off process, each network element initiate the flow process of the carrying of deletion handoff failure.The flow process of the carrying of existing deletion handoff failure does not need the carrying of judging whether the opposite end network element successfully deletes handoff failure, the respective resources that all needs to delete the local terminal network element.Therefore, if opposite end network element response timeout (as losing message between network element), the local terminal network element is still deleted the bearing resource of handoff failure, then may cause the inconsistent situation of resource.
And in embodiments of the present invention, the carrying of deletion handoff failure is finished by network element internal after hand-off process, and the hand-off process of network element need after receiving the response message of opposite end, carry out (as SGW need receive that PGW returns first revise bearing response message after, carry out hand-off process again, and after hand-off process is finished, delete the carrying of handoff failure again), can reduce the inconsistent possibility of resource between network element effectively.
