PGW 30, are used for behind the carrying ID delete command of receiving from comprising of target SGW 10 of virtual TEID correspondence the bearing resource that deletion distributes from the carrying as this virtual TEID correspondence.
Wherein, when carrying out the SGW reorientation, MME 20 can send to target SGW 10 and create conversation request message, comprises carrying ID in this establishment conversation request message.
Concrete, the carrying ID in the establishment conversation request message comprises the carrying ID that needs foundation carrying is corresponding and needs the carrying ID of deleting bearing correspondence; Further, also may in the corresponding carrying ID of needs foundation carrying, comprise default bearing; Or in needing the carrying ID of deleting bearing correspondence, also may comprise default bearing; Or set up the corresponding carrying ID of carrying and needing at needs and all comprise default bearing among the carrying ID of deleting bearing correspondence, these two default bearings are inequality.
A PDN (Packet Data Network, Packet Data Network) connects corresponding default bearing, also might correspond to few dedicated bearer.
Target SGW 10 need distribute a TEID and corresponding SGW address to be used for PGW transmission downlink business for each carrying of carrying the ID correspondence after receiving the establishment conversation request message of carrying ID from comprising of MME.
For carrying that can not successful Resources allocation, target SGW 10 can determine to carry the carrying that can not distribute bearing resource in the carrying of ID correspondence earlier, distribute a virtual TEID for each carrying of determining then, can be virtual carrier context of each load creating more further, virtual TEID is saved in the virtual carrier context.The carrying ID that can also comprise the carrying of virtual TEID correspondence in the virtual carrier context.
Wherein, virtual TEID can be an invalid reserved value.
If can not comprise default bearing in the carrying of successful Resources allocation, then target SGW 10 can also determine that the PDN of default bearing correspondence connects, for all carryings under this PDN connection distribute virtual carrier contexts, create virtual carrier resource (comprising virtual TEID etc.) then then.
Target SGW 10 is after can not distributing the carrying of bearing resource to distribute virtual TEID for each, target SGW sends to PGW and revises bearing request message, be included as successfully the TEID and the corresponding SGW address of the carrying distribution of Resources allocation in this modification bearing request message, and be the virtual TEID and corresponding SGW address that can not distribute the carrying distribution of bearing resource;
PGW 30 can't know which TEID is virtual TEID after receiving and revising bearing request message, and PGW 30 can handle according to normal procedure, promptly uses SGW address and TEID (comprising virtual TEID and effective TEID) to send downlink grouped data.
PGW 30 can return the modification bearing response message to target SGW 10 after receiving and revising bearing request message; Target SGW 10 is after the modification bearing response message of receiving from PGW 30, send establishment conversational response message to MME 20, this establishment conversational response message is included as successfully the carrying ID and the corresponding SGW address of the carrying distribution of Resources allocation, and be the carrying ID that can not distribute the carrying distribution of bearing resource, can not distribute the carrying ID of bearing resource will be placed in the failure carrying ID tabulation.
Similar with PGW 30, MME 20 can't know which TEID is virtual TEID after receiving and creating conversational response message, and MME 20 can handle according to normal procedure.
Need to prove, the embodiment of the invention is not limited to the carrying ID notice PGW 30 by the carrying of revising virtual TEID that bearing request message distributes target SGW 10 and virtual TEID correspondence, and the carrying ID of virtual TEID correspondence is notified to MME 20 by creating conversational response message, the message of the carrying ID notice PGW 30 of the virtual TEID that other can distribute target SGW 10 and the carrying of virtual TEID correspondence, and the suitable equally embodiment of the invention of message that the carrying ID of virtual TEID correspondence is notified to MME 20.
After MME 20 receives failure carrying ID tabulation, during the bearing resource of the carrying of the carrying ID correspondence in needs deletion failure carrying ID tabulation (bearing resource that comprises all carryings under the bearing resource of delete certain dedicated bearer or the PDN connection), can send delete command to target SGW 10, comprise the carrying ID of the carrying of needs deletion in this delete command.Shan Chu carrying is the carrying that target SGW 10 can not distribute bearing resource if desired, and then the carrying ID that comprises in this delete command is the carrying ID of virtual TEID correspondence.
Target SGW 10 checks the carrying ID that whether has in the context in the middle delete command behind the delete command of receiving from MME 20, if having, then transmit this delete command to PGW 30.
If carrying ID is the carrying ID of virtual TEID correspondence, because target SGW 10 be for can not distribute the carrying of bearing resource to distribute virtual TEID, so have virtual TEID in the virtual context, then target SGW 10 also can be transmitted to this delete command PGW 30; Accordingly, the bearing resource of the carrying of the carrying ID correspondence that PGW 30 deletion self distributes, thus realize that PGW 30 can delete the bearing resource of the carrying correspondence that target SGW 10 can not distribute.
Further, if MME 20 needs the bearing resource of certain dedicated bearer of deletion, MME need initiate the deleting load-bearing process, and then delete command is the deleting bearing order;
If MME 20 needs deletion PDN to connect the bearing resource of all carryings down, MME need initiate PDN and connect dispose procedure, and then delete command is the deletion conversation request message.
As shown in Figure 2, embodiment of the invention network equipment comprises: distribution module 100, notification module 110 and processing module 120.
Wherein, the carrying ID of the virtual TEID that notification module 110 will distribute and the carrying of virtual TEID correspondence is by revising bearing request message notice PGW, after the modification bearing response message of receiving from PGW, the carrying ID of the carrying of the virtual TEID correspondence of distributing is placed failure carrying tabulation, by creating conversational response message informing MME.
Further, distribution module 100 can also be the virtual context of the load creating that can not distribute bearing resource.
Wherein, the network equipment of the embodiment of the invention can be SGW, also can be other network equipment.
As shown in Figure 3, the method for embodiment of the invention bearing resource release comprises the following steps:
The carrying ID of the virtual TEID that step 302, target SGW will distribute and the carrying of virtual TEID correspondence notice PGW is with the carrying ID notice MME of the carrying of virtual TEID correspondence.
When step 303, target SGW comprise the carrying ID of carrying of virtual TEID correspondence in the delete command of receiving from described MME, this delete command is transmitted to PGW, is used to indicate the bearing resource of the carrying of PGW deleting bearing ID correspondence.
Wherein, also comprise before the step 301:
When carrying out the SGW reorientation, MME can send to target SGW and create conversation request message, comprises carrying ID in this establishment conversation request message.
Concrete, the carrying ID in the establishment conversation request message comprises the carrying ID that needs foundation carrying is corresponding and needs the carrying ID of deleting bearing correspondence; Further, set up the corresponding carrying ID of carrying and/or need at needs and also can comprise default bearing among the carrying ID of deleting bearing correspondence.
A PDN connects corresponding default bearing, also might correspond to few dedicated bearer.
In the step 301, target SGW need distribute a TEID and corresponding SGW address to be used for PGW transmission downlink business for each carrying of carrying the ID correspondence after receiving the establishment conversation request message of carrying ID from comprising of MME.
For carrying that can not successful Resources allocation, target SGW can determine to carry the carrying that can not distribute bearing resource in the carrying of ID correspondence earlier, distribute a virtual TEID for each carrying of determining then, can be virtual carrier context of each load creating more further, virtual TEID is saved in the virtual carrier context.The carrying ID that can also comprise the carrying of virtual TEID correspondence in the virtual carrier context.
Wherein, virtual TEID can be an invalid reserved value.
If can not comprise default bearing in the carrying of successful Resources allocation, then target SGW can also determine that the PDN of default bearing correspondence connects, for all the load creating virtual carrier contexts (virtual context of a load creating) under this PDN connection, create virtual carrier resource (comprising virtual TEID etc.) then then.
In the step 302, target SGW sends to PGW and revises bearing request message, be included as successfully the TEID and the corresponding SGW address of the carrying distribution of Resources allocation in this modification bearing request message, and be the virtual TEID and corresponding SGW address that can not distribute the carrying distribution of bearing resource;
PGW can't know which TEID is virtual TEID after receiving and revising bearing request message, and PGW can handle according to normal procedure, promptly uses SGW address and TEID (comprising virtual TEID) to send downlink grouped data.
PGW can return the modification bearing response message to target SGW after receiving and revising bearing request message; Target SGW is after the modification bearing response message of receiving from PGW, send establishment conversational response message to MME, this establishment conversational response message is included as successfully the carrying ID and the corresponding SGW address of the carrying distribution of Resources allocation, and be the carrying ID that can not distribute the carrying distribution of bearing resource, can not distribute the carrying ID of bearing resource will be placed in the failure carrying ID tabulation.
After MME receives and creates conversational response message, the carrying tabulation that is specified to the carrying tabulation of distribution of work resource and can not distributes bearing resource, MME can handle according to normal procedure.
Need to prove, the embodiment of the invention is not limited to the carrying ID notice PGW by the carrying of revising virtual TEID that bearing request message distributes target SGW and virtual TEID correspondence, and the carrying ID of virtual TEID correspondence is notified to MME 20 by creating conversational response message, the message of the carrying ID notice PGW of the virtual TEID that other can distribute target SGW and the carrying of virtual TEID correspondence, and the suitable equally embodiment of the invention of message that the carrying ID of virtual TEID correspondence is notified to MME 20.
After MME receives failure carrying ID tabulation, during the bearing resource of the carrying of the carrying ID correspondence in needs deletion failure carrying ID tabulation (bearing resource that comprises all carryings under the bearing resource of delete certain dedicated bearer or the PDN connection), can send delete command to target SGW, comprise the carrying ID of the carrying of needs deletion in this delete command.Shan Chu carrying is the carrying that target SGW can not distribute bearing resource if desired, and then the carrying ID that comprises in this delete command is the carrying ID of virtual TEID correspondence.
In the step 303, target SGW checks the carrying ID that whether has in the context in the middle delete command behind the delete command of receiving from MME, if having, then transmit this delete command to PGW.
If carrying ID is the carrying ID of virtual TEID correspondence, because target SGW be for can not distribute the carrying of bearing resource to distribute virtual TEID, so have virtual TEID in the virtual context, then target SGW also can be transmitted to PGW with this delete command; Accordingly, the bearing resource of the carrying of the carrying ID correspondence that PGW deletion self distributes, thus realize that PGW can delete the bearing resource of the carrying correspondence that target SGW can not distribute.
Further, if MME need delete the bearing resource of certain dedicated bearer, MME need initiate the deleting load-bearing process, and then delete command is the deleting bearing order;
Connect the bearing resource of all carryings down if MME need delete PDN, MME need initiate PDN and connect dispose procedure, and then delete command is the deletion conversation request message.
Wherein, the embodiment of the invention can be applied to the SGW reorientation in X2 handoff procedure, the S1 handoff procedure tracing section updating process.
Embodiment of the invention target SGW can distribute the carrying of bearing resource to set up the virtual carrier context for failing on it, carrying corresponding virtual TEID and carrying ID in its virtual carrier context, target SGW is notified to PGW with the virtual carrier resource information, and PGW can be with bearer path converting into target SGW side like this.
If connecting some carrying down, can not successfully create a PDN at target SGW, MME sends deleting bearing order (Delete Bearer Command) message in the dedicated bearer delete procedure of being initiated by MME after the SGW repositioning process is finished so, target SGW can be transmitted to PGW with it, and PGW is the corresponding bearing resource of deletion therefore;
If establishing a plurality of PDN, UE connects, so after target SGW repositioning process is finished, when MME receives target SGW when indicating certain PDN to connect the establishment conversation failure of default bearing down, MME connects by discharging this PDN to target SGW side transmission deletion conversation request response (Delete SessionRequest/Response) process, and MME indicates continuation to initiate deletion conversation request response (Delete Session Request/Response) process to delete the corresponding bearing resource of being safeguarded on the P-GW of this PDN connection to PGW to target SGW in deletion conversation request (the Delete Session Request) message of this process.
Be example with the X2 handoff procedure below, describe that SGW reorientation and the SGW reorientation in the X2 handoff procedure in S1 handoff procedure and the tracing section updating process are similar, do not repeat them here.
As shown in Figure 4, the method for embodiment of the invention SGW reorientation comprises the following steps:
Step 401, target eNB (evolution base station) finish and UE (user terminal) between after the hand-off execution process, to MME transmit path conversion request message.
Step 402, MME send to target SGW and create conversation request message.
(S5/S8 adopts GTP (GPRS Tunneling Protocol for PGW address when comprising PGW reception uplink service in this establishment conversation request message and TEID, GPRS Tunnel Protocol)) or generic route encapsulation key GRE (Generic Route Encapsulation) key (S5/S8 adopts PMIP (ProxyMobile IP Protocol, proxy mobile IP protocol) agreement), that has accepted EPS (Evolved Packet System, evolved packet system) carrying (promptly need set up carrying) is used to send the eNB address of downlink business and the TEID that eNB distributes, and S5/S8 interface protocol type and the carrying ID (the carrying ID that promptly needs the deleting bearing correspondence) that can not accept the EPS carrying.
Concrete, comprise two carrying tabulations in the establishment conversation request message, comprise the carrying ID that will set up in the tabulation, comprise the unacceptable carrying of MME ID in another tabulation.
Step 403, target SGW send to PGW and revise bearing request message.
Concrete, target SGW sends downlink business for each carrying distributes a TEID and corresponding SGW address to be used for PGW.SGW is that unacceptable carrying distributes the descending TEID on the S5/S8 interface.
For target SGW can not successful Resources allocation carrying, target S-GW specifies the virtual TEID on the S5/S8 interface for it and is kept in the virtual carrier context of foundation.
SGW sends and revises bearing request message to PGW, and it comprises the S-GW address and the TEID that are used for downlink business that SGW distributes, and the TEID of the carrying correspondence of the Resources allocation that fails and S-GW address.
Step 404, PGW send to target SGW and revise bearing response message.
PGW also uses the address and the TEID that newly receive to start to target S-GW transmission downlink grouped data.These downlink datas will use this new downlink path to arrive target eNB by target SGW.
Step 405, target S-GW send and create conversational response message to MME.
Concrete, comprise SGW address and up TEID in the establishment conversational response message.If target S-GW can not distribute effective bearing resource for some carrying that will create of MME appointment, then in the deleting bearing context of this message, comprise the carrying ID of the carrying correspondence of failure.
If target S-GW can not admit all carryings under certain PDN connection, then the deleting bearing context of target S-GW in the establishment conversational response message that MME sends comprises the carrying ID of all carryings under this PDN connection.
Step 406, MME confirm path switching request information by path conversion request response message to eNB.
Path switching request information comprises SGW address and the up TEID that is used for the uplink service transmission, and at this moment target eNB is changeed follow-up upstream packet before using new SGW address and TEID.
If some EPS carrying can not be in the core net successful conversion, which carrying MME must indicate to set up in the conversion request response message of path, and connects the bearing resource that release fails to set up in the dispose procedure at deleting load-bearing process or the PDN that MME initiates.Target eNB must be deleted corresponding bearer context when notice can not be set up some carrying in core net.If some dedicated bearer needs deletion, then MME initiates the deleting load-bearing process.If all carryings under certain PDN connection need deletion, then MME initiates PDN connection dispose procedure, promptly deletes the conversation request response process.
Step 407, target eNB discharge resource signaling by sending, and to source eNB notice handover success, target eNB and source eNB trigger interface-free resources and discharge.
Step 408, MME send the bearing resource of deleting among the conversation request message source of release SGW to source SGW.MME indication source SGW does not continue to send the deletion conversation request message to PGW.
Step 409, source SGW return deletion conversational response message to MME.
If satisfy TS23.401 defined tracking area trigger condition, UE initiating updating of tracking area process.
The bearing resource that need delete certain dedicated bearer with MME is that example describes below, and MME need delete PDN, and to connect the process of the process of the bearing resource of all carryings down and the bearing resource that MME need delete certain dedicated bearer similar, do not repeat them here.
As shown in Figure 5, the method for embodiment of the invention load bearing deactivation comprises the following steps:
Step 501, UE deletion and the relevant bearer context of institute's releasing bearing.
Owing to local reason may discharge the UE radio bearer that is in connection (ECM-CONNECTED) state, for example abnormal resource restriction or radio condition do not allow eNB to keep all GBR that distributed (Guaranteed Bit Rate guarantees bit rate) carrying.
Step 502, when the radio bearer of eNB release steps 0, eNB sends carrying to MME and discharges indication.
This indication may be that carrying discharges request message, or message is finished in initial context foundation, handoff request is replied and the response of UE bearer context, and path switching request information also can be that carrying discharges indication.
Step 503, MME send the deleting bearing command messages to SGW.
The purpose of deleting bearing command messages is the selected dedicated bearer of deletion.The carrying ID that comprises the deleting bearing correspondence of wanting in this message.This carrying ID may be the carrying ID of virtual TEID correspondence.
When step 504, SGW have carrying ID in the deleting bearing command messages in the carrying ID of the carrying of the TEID correspondence of the bearer context of determining self, transmit and send the deleting bearing command messages to PGW.
Step 505, PGW deletion sends the deleting bearing request message to SGW from the bearing resource that the carrying as this TEID correspondence distributes, and includes the carrying ID of carrying correspondence of the bearing resource of deletion in its message.
Step 506, SGW transmit the deleting bearing request message and give MME.
Step 507, MME deletion and the relevant bearer context of institute's deleting bearing, and to SGW response deleting bearing response message.
Step 508, SGW deletion and the relevant bearer context of institute's deleting bearing, and to PGW transmission deleting bearing response message.
