Embodiment

Below in conjunction with accompanying drawing the technical scheme that the embodiment of the invention provides is described.

Embodiment one, and the method for recovery reserved GBR load as shown in Figure 1.

Step 1, MME receive the message relevant with terminal.

The message relevant with terminal that MME receives can be the message that terminal sends, and for example, is in the service request information of the terminal transmission of connected state; Again for example, be in the service request information of the terminal transmission of Idle state; Also have the tracing section updating request message that terminal sends etc.The message that terminal sends can be sent to MME by intermediate equipment such as base station.

The message relevant with terminal that MME receives also can be the message that other network entity sends, for example, in the handoff procedure of terminal, acknowledge message is finished in the switching that switching request acknowledgement message that the target BS that target MME receives sends and source-end networks equipment send.

When the message relevant with terminal is the message of terminal transmission, can carry the information relevant in this message with recovering reserved GBR load.The reserved GBR load tabulation that information relevant with recovering reserved GBR load such as needs recover recovers the information of whole reserved GBR loads etc. for another example.

Step 2, MME determine and need the reserved GBR load of above-mentioned terminal be recovered.

The information that MME carries in can the message relevant with terminal according to its reception is determined needs the reserved GBR load of terminal is recovered; For example, the reserved GBR load tabulation that recovers according to the needs that carry in the message is determined needs the reserved GBR load of terminal is recovered; Again for example, determining needs according to the information of the whole reserved GBR loads of recovery that carry in the message recovers etc. the reserved GBR load of terminal.

MME also can determine and need the reserved GBR load of terminal be recovered when find that there is the GBR carrying that keeps attitude in this terminal; For example, do not carry in the message relevant that receives at MME and recover under the situation of the relevant information of reserved GBR load with terminal, MME finds this terminal and whether has the GBR carrying that keeps attitude, there is the carrying that keeps attitude GBR if find this terminal, then determines and need the reserved GBR load of this terminal be recovered.

Step 3, MME send to PDN GW and carry first Indication message that recovers reserved GBR load information, recover the core-network side carrying of this reserved GBR load correspondence with indication PDN GW; MME sends second Indication message that carries quality of service information to the base station, recovers the S1 interface bearing and the wireless side carrying of reserved GBR load correspondence according to the quality of service information that carries in second Indication message with the indication base station.The wireless side carrying is an empty port load-supporting.

The recovery reserved GBR load information of carrying in above-mentioned first Indication message can be the reserved GBR load sign and the quality of service information that need to recover.When the reserved GBR load of needs recovery was many, the sign and the quality of service information of the reserved GBR load that MME can recover all needs only sent by one first Indication message, also can be by many first Indication messages transmissions.That is to say, article one, can carry an identification information and a quality of service information that needs the reserved GBR load of recovery in first Indication message, at least two reserved GBR loads that need to recover that also can carry in all reserved GBR loads that need recover identify and quality of service information, can also carry all reserved GBR loads that need recover sign and quality of service information.Need to prove, also can not carry quality of service information in above-mentioned first Indication message.

Carry at first Indication message under the situation of quality of service information, MME need obtain the quality of service information of the reserved GBR load that needs recovery earlier, and the mode that MME obtains quality of service information can comprise following two kinds:

Mode one, at E-UTRAN reduce to quality of service information before zero owing to store reserved GBR load speed among the MME, therefore, MME can obtain the quality of service information that needs the reserved GBR load correspondence recovered from its canned data.

Mode two, at UTRAN because MME can receive the PDP Context information that carries quality of service information, therefore, MME can obtain the quality of service information that needs the reserved GBR load correspondence recovered from the PDP Context information that it receives.

First Indication message that MME sends can transfer to PDN GW by the gateway of intermediate equipment such as terminal.Under there was more news in the gateway of terminal, MME can be sent to PDN GW with first Indication message by the gateway after upgrading; For example, the terminal initiating updating of tracking area, the tracing section updating request message that the MME receiving terminal sends by the base station, MME is not selecting under the situation of new gateway for terminal, and MME sends to PDN GW by the current gateway of terminal and carries first Indication message that recovers reserved GBR load information; MME is selecting for terminal under the situation of new gateway, and MME is by carrying first Indication message that recovers reserved GBR load information for the new gateway of selecting of terminal sends to PDN GW.

PDN GW determines the quality of service information of this reserved GBR load after receiving first Indication message, and the maximum rate of reserved GBR load is set according to the quality of service information of determining.It is multiple that PDN GW determines that the mode of the quality of service information of reserved GBR load has, as PDN GW by carrying out the quality of service requirement that information interaction obtains this reserved GBR load with PCRF, and the quality of service information of determining this reserved GBR load according to the quality of service requirement that obtains and current network resources situation; The PDN GW quality of service information requirement of obtaining this reserved GBR load for another example according to local collocation strategy, and require and the current network resources situation is determined the quality of service information of this reserved GBR load according to the quality of service information that obtains; Also have, PDN GW obtains the quality of service information that carries in first Indication message, and determines the quality of service information of this reserved GBR load according to the quality of service information that carries in first Indication message and current network resources situation.Need to prove that PDN GW also can adopt alternate manner to determine the quality of service information of reserved GBR load, the embodiment of the invention does not limit the specific implementation process that PDN GW determines the quality of service information of reserved GBR load.

PDN GW determines the process of quality of service information of reserved GBR load as under the situation about allowing in the real network resource according to the quality of service information that carries in first Indication message and current network resources situation, distribute the quality of service information that is not less than the quality of service information that carries in first Indication message for reserved GBR load; Under the situation that the real network resource allows, distribute the service quality of carrying in first Indication message for reserved GBR load for another example; Also have under the unallowed situation of real network resource, be lower than quality of service information of the quality of service information that carries in first Indication message or the like for reserved GBR load distributes.The embodiment of the invention does not limit PDN GW determines the quality of service information of reserved GBR load according to quality of service information that carries in first Indication message and current network resources situation specific implementation process.

The quality of service information of the reserved GBR load that above-mentioned PDN GW determines can only be maximum rate, certainly, also can comprise maximum rate and other parameter.

PDN GW is after determining the quality of service information of reserved GBR load, according to the core-network side carrying that this quality of service information of determining recovers above-mentioned reserved GBR load correspondence, promptly carry Resources allocation according to the core-network side that this quality of service information of determining is the reserved GBR load correspondence.The core-network side carrying of reserved GBR load correspondence for example, is set according to the maximum rate of determining.

PDN GW returns response message at first Indication message to MME after the core-network side carrying that has recovered the reserved GBR load correspondence.Can carry the quality of service information that PDN GW determines in this response message, the reserved GBR load sign that also can carry the quality of service information that PDNGW determines and successfully recover the core-network side carrying.Need to prove that it can be the quality of service information that MME obtains that above-mentioned MME is sent to the quality of service information that carries in second Indication message of base station from this response message.Certainly, the quality of service information that carries in second Indication message also can be the quality of service information that MME adopts alternate manner to obtain, and for example, target MME is from switching the quality of service information that former end obtains.

In addition, PDN GW is after receiving first Indication message and determining the quality of service information of reserved GBR load, can trigger the dedicated bearing modification process of existing modification service quality according to this quality of service information of determining, thereby utilize this bearing modification flow process to recover the core-network side carrying of above-mentioned reserved GBR load correspondence.No matter terminal is in Idle state, still is in connected state, utilizes the above-mentioned bearing modification flow process that is triggered all can realize the recovery of the core-network side carrying of reserved GBR load correspondence.Utilize the above-mentioned bearing modification flow process that is triggered can also the S1 interface bearing and the wireless side carrying of reserved GBR load correspondence be recovered.The core-network side of utilizing the bearing modification flow process to recover the reserved GBR load correspondence is carried and the specific implementation process of S1 interface bearing and wireless side carrying can be not described in detail at this for existing implementation procedure.Need to prove, if PDN GW triggers the bearing modification flow process, then second Indication message of MME transmission can send to the message base station, that carry quality of service information for MME in the bearing modification flow process, is bearing modification request or the session management request that MME sends in the bearing modification flow process as second Indication message.The quality of service information that carries in second Indication message can only comprise maximum rate, certainly, also can comprise maximum rate and out of Memory.

The base station is behind second Indication message that receives the MME transmission, the reserved GBR load correspondence of exist to need recovering, maximum rate is under the situation of zero S1 interface bearing and wireless side carrying, the base station does not need to carry out the process of setting up of S1 interface bearing and wireless side carrying again, but the maximum rate of S1 interface bearing and wireless side carrying directly is set according to the quality of service information in second Indication message, be nonzero value by zero adjustment directly promptly with the maximum rate of S1 interface bearing and wireless side carrying; Do not exist the reserved GBR load correspondence, maximum rate is under the situation of zero S1 interface bearing and wireless side carrying, the S1 interface bearing of the reserved GBR load correspondence that needs recovery and the process of setting up of wireless side carrying need be carried out in the base station, the maximum rate of S1 interface bearing and wireless side carrying is set according to the quality of service information in second Indication message then, again.

If above-mentioned two kinds of situations all might exist at the place, base station, but only may there be a kind of situation at a concrete reserved GBR load, then the base station is after receiving second Indication message, need judge whether earlier that the reserved GBR load correspondence, successful foundation, the maximum rate that exist needs to recover are zero S1 interface bearing and wireless side carrying, then, carry out corresponding operation according to judged result again.If only there be a kind of in above-mentioned two kinds of situations at base station place, then the base station does not need to carry out above-mentioned deterministic process, but after receiving second Indication message, directly carries out above-mentioned corresponding operation.For example, the S1 interface bearing of the reserved GBR load correspondence of need recovering and wireless side carrying one fix on the base station and receive not carry out before second Indication message and set up operation, then the base station is after receiving second Indication message, directly set up the S1 interface bearing and the wireless side carrying of this reserved GBR load correspondence, and the maximum rate of S1 interface bearing and wireless side carrying is set according to the quality of service information that carries in second Indication message.

When the base station receives second Indication message, successfully set up, maximum rate is that zero S1 interface bearing and wireless side carrying can be: under terminal is in Idle state, MME is after the service request that receives the terminal transmission, and the maximum rate of the reserved GBR load correspondence that the indication base station is set up is zero S1 interface bearing and wireless side carrying.Under terminal was in Idle state, it was zero S1 interface bearing and the specific implementation process of wireless side carrying such as the description among the following embodiment that maximum rate is set up in MME indication base station.

Need to prove that in the description of the foregoing description one, MME can send first Indication message earlier, sends second Indication message again; MME also can send second Indication message earlier, sends first Indication message again.The different sending orders of first Indication message, second Indication message exemplify description in the following embodiments.

From the description of the foregoing description one as can be known, embodiment one triggers the core-network side carrying that PDN GW recovers the reserved GBR load correspondence by MME, and trigger S1 interface bearing and the wireless side carrying that recovers the reserved GBR load correspondence in the base station, thereby successfully recovered reserved GBR load by MME.

Embodiment one has multiple different specific implementation process, is elaborated below in conjunction with several specific implementation processes of accompanying drawing to embodiment one.

Embodiment two, terminal such as UE (subscriber equipment) are in Idle state, the service request procedure that UE initiates under the Idle state earlier makes the state of UE become connected state, then, UE initiates the service request procedure of connected state, recovers the reserved GBR load of UE in the service request procedure of the UE under being in connected state.

The specific implementation process of embodiment two as shown in Figure 2.

Among Fig. 2, step 1, the UE that is in connected state send service request information to MME.Carry cells such as S-TMSI in this service request information.Can also increase in the service request information that UE sends and carry the cell that is used to carry the information relevant with recovering reserved GBR load.The sign of the reserved GBR load that the cell loaded information of this increase can be recovered for needs also can be for recovering the indication information of whole reserved GBR loads.When the cell loaded information that increases during for the sign of the reserved GBR load that needs to recover, this sign can exist with the form of GBR bearing identification tabulation.The indication information that recovers whole reserved GBR loads can be 1 bit indicating bit etc.

Certainly, also can not carry the cell of above-mentioned increase in the service request information that UE sends, in the present embodiment, the cell that service request information is not carried above-mentioned increase can be expressed as the whole reserved GBR loads of requirement recovery in this service request procedure, also can be expressed as in this service request procedure and not require the whole reserved GBR loads of recovery.The implication of the concrete expression of service request information need clearly be stipulated in each network equipment.If in the service request procedure of the terminal that is in connected state, do not require the recovery reserved GBR load, then can in other process, recover reserved GBR load, for example, when UE need utilize the GBR carrying that keeps attitude to carry out business, UE can initiate the bearing resource modification process, to recover reserved GBR load in the bearing resource modification process.UE initiates the bearing resource modification process, and the specific implementation process of recovery reserved GBR load is on the books in other embodiments in this flow process.

Step 2, eNodeB receive the service request information that UE sends, and this service request information is transmitted to MME.

After step 2a, MME received service request information, determining needed to recover reserved GBR load, and then MME sends and upgrades bearing request message (i.e. first Indication message).

MME determines mode that need to recover reserved GBR load to be had multiplely, and when carrying the reserved GBR load tabulation in the service request information that receives at MME, MME determines needs to recover reserved GBR load; Carry the indication information that recovers whole reserved GBR loads and this indication information for another example when representing that needs recover reserved GBR load in the service request information that MME receives, MME determines needs the recovery reserved GBR load; Also have, not carrying the information representation relevant with recovering reserved GBR load in MME in the default service requests message recovers under the situation of whole reserved GBR loads, after MME receives the service request information of not carrying above-mentioned increase cell, search the reserved GBR load that whether has this UE, after finding the reserved GBR load that has this UE, determining needs to recover reserved GBR load.

Can carry the QoS of the GBR carrying tabulation of the reservation attitude that needs recovery and each the GBR carrying correspondence in the tabulation in the renewal bearing request message that MME sends, promptly MME utilizes one to upgrade the information that bearing request message sends all reserved GBR loads that need recover.When the reserved GBR load of needs recovery has many, MME also can upgrade the information that bearing request message sends the reserved GBR load that needs recovery by many, for example, one is upgraded bearing request message and only carries a sign that needs the reserved GBR load that recovers and QoS etc.

The QoS that upgrades the reserved GBR load that the needs that carry in the bearing request message recover can be the QoS of reserved GBR load when normally moving.In the E-UTRAN environment, for discharge the reserved GBR load that forms owing to the S1 interface, owing to preserve the QoS that maximum rate is reduced to the carrying before zero among the MME, therefore, the QoS when MME can obtain reserved GBR load and normally moves from its canned data.For the maximum rate that passes over from UTRAN is that zero carrying (is that UE is under the UTRAN environment, having maximum rate is zero carrying, afterwards, UE moves to the E-UTRAN environment from the UTRAN environment, because the QoS that consults when including reserved GBR load in the PDP Context of UE under former UTRAN environment that receive of MME and normally moving, therefore, MME can get access to the QoS of reserved GBR load when normally moving from the PDP Context information that received in the past.

Need to prove that the renewal bearing request message here only is a kind of explanation that exemplifies, the step 2a of present embodiment also can adopt other message, and present embodiment does not limit the message name of concrete employing.

Step 2b, Serving GW should upgrade bearing request message and be transmitted to PDN GW after receiving the renewal bearing request message of MME transmission.Still carry in the renewal bearing request message that Serving GW transmits and recover reserved GBR load information, as carry reserved GBR load tabulation and QoS, carry reserved GBR load sign and QoS for another example.

After step 2c, PDN GW receive the renewal bearing request message that Serving GW sends, obtain the recovery reserved GBR load information of carrying in the bearing request message of upgrading, and need to determine the QoS of the reserved GBR load that recovers.PDN GW is provided with the core-network side carrying of reserved GBR load correspondence according to the QoS of the reserved GBR load of determining.

The QoS of the reserved GBR load that determine to need recovers can for: PDN GW by carrying out information interaction or obtain qos requirement at reserved GBR load according to local collocation strategy with PCRF, then, determine the QoS of reserved GBR load again according to the qos requirement of the concrete condition of current network resources and above-mentioned acquisition.The object lesson of the QoS of another definite reserved GBR load that need recover is: reduce to zero reserved GBR load at the maximum rate of coming from the UTRAN band, PDN GW provides a new QoS who is not less than the QoS of former requirement according to the current network resources situation for reserved GBR load.The QoS of the former requirement here is meant the QoS of reserved GBR load when normal operation.Certainly, here be not less than also can be for being equal to or less than.For example, PDN GW can will upgrade the QoS that carries in the bearing request message QoS as reserved GBR load under the situation that the current network resources situation allows, promptly PDN GW carries according to upgrading the core-network side that the QoS that carries in the bearing request message is provided with the reserved GBR load correspondence under the situation that the current network resources situation allows.

Step 2d, PDN GW are after the core-network side carrying that is provided with the reserved GBR load correspondence, send and upgrade bearing response message, can carry the QoS of the reserved GBR load that successfully recovers and the tabulation that successfully recovers reserved GBR load in this renewal bearing response message.The successful recovery here is meant the successful recovery of core-network side carrying.No matter PDN GW has successfully recovered all reserved GBR loads, has still recovered the part reserved GBR load, all can carry the tabulation of the reserved GBR load that successfully recovers in this renewal bearing response message.A kind of simple variation is: when successfully recovering all reserved GBR loads, can not carry the tabulation of the reserved GBR load that successfully recovers, and when successful recovered part reserved GBR load, can carry the tabulation of the reserved GBR load that successfully recovers.Another kind of simple variation is: the reserved GBR load that recovers at needs only has one and when successfully having been recovered, the tabulation that can not carry the reserved GBR load that successfully recovers.Above-mentionedly also be applicable in the following respective embodiments no longer repeat specification in the following embodiments at upgrading the description of carrying the tabulation that successfully recovers reserved GBR load in the bearing response message.

The renewal bearing response message that step 2e, Serving GW will receive is transmitted to MME, still can carry the QoS of the reserved GBR load that successfully recovers and the carrying tabulation that success recovers in this renewal bearing response message.To step 4.

Fig. 2 acceptance of the bid is marked with step 3, and the subscription authentication of step 3 is applied to be in the service request procedure of UE of Idle state, and in the present embodiment, because UE is in connected state, therefore, this step does not need to carry out.

Step 4, MME send S1 bearer context request message (i.e. second Indication message) to eNodeB after receiving and upgrading bearing response message, are that the reserved GBR load that successfully recovers the core-network side carrying recovers the S1 carrying with indication eNodeB.Carry QoS in the S1 bearer context request message, this QoS is for upgrading the QoS that carries in the bearing response message.Can also carry the reserved GBR load identification information that successfully recovers the core-network side carrying in the S1 bearer context request message, this identification information is for upgrading the identification information that carries in the bearing response message.An object lesson that recovers the S1 interface bearing is: set up the S1 interface bearing according to the QoS in the S1 bearer context request message.

Step 5, eNodeB are that the reserved GBR load that successfully recovers the core-network side carrying recovers corresponding wireless side carrying.

An object lesson that recovers the wireless side carrying is: after successfully setting up the S1 carrying, eNodeB calculates the QoS of the wireless side carrying of reserved GBR load correspondence according to the QoS in the S1 bearer context request message, then, set up the wireless side carrying according to the QoS that calculates.Successfully recover the S1 interface bearing and the wireless side carrying of reserved GBR load correspondence by step 4 and 5.

Step 6, UE can send upstream data according to the reserved GBR load that above-mentioned success recovers.

Step 7, eNodeB send the S1 bearer context to MME and finish message, with the restoration result of notice MME reserved GBR load.

Step 8, MME send to Serving GW and upgrade bearing request message.Can not successfully set up if there is core-network side to carry corresponding empty port load-supporting, MME will trigger the carrying dispose procedure so.

MME in the foregoing description two is after the service request that receives the UE transmission that is in connected state, by send the renewal bearing request message that carries reserved GBR load tabulation and QoS to PDN GW, make PDN GW upgrade the core-network side carrying that bearing request message is recovered the reserved GBR load correspondence according to this; PDN GW is by sending the QoS carry the reserved GBR load that successfully recovers the core-network side carrying and successfully recovering the renewal bearing response message of the reserved GBR load sign of core-network side carrying to MME, make MME upgrade bearing response message according to this and send to eNodeB and carry that the reserved GBR load that successfully recovers the core-network side carrying identifies and the S1 bearer context request message of QoS; ENodeB can recover the S1 interface bearing and the wireless side carrying of reserved GBR load correspondence according to the S1 bearer context request message that receives.Thereby in being in the process of connected state, UE successfully recovers reserved GBR load.

Embodiment three, UE are in Idle state, and UE initiates earlier Idle state service request procedure down, in this service request procedure, set up the reserved GBR load correspondence, maximum rate is that zero S1 interface bearing and wireless side are carried.After this service request procedure was finished, UE was in connected state.The UE that is in connected state initiates the connected state service request procedure again, serves as the zero S1 interface bearing and the QoS of wireless side carrying with core-network side carrying that recovers the reserved GBR load correspondence and the maximum rate that is modified in Idle state foundation, improves maximum rate.The specific implementation process of embodiment three is shown in Fig. 3 a and Fig. 3 b.

Fig. 3 a shows the service request procedure under the UE initiation Idle state that is in Idle state.In the service request procedure shown in Fig. 3 a, set up the reserved GBR load correspondence, maximum rate is zero S1 interface bearing and wireless side carrying.

Among Fig. 3 a, step 1, the UE that is in Idle state send service request information to MME, carry cells such as S-TMSI in this service request information.

Step 2, eNodeB receive service request information, and this service request information is transmitted to MME.

The authentication process that step 3, MME initiate NAS message.

Step 4, after authentication success, MME sends S1 bearer context request message to eNodeB, to set up the S1 interface bearing.At MME after to find this network element internal memory be zero reserved GBR load at maximum rate, it is zero S1 interface bearing that MME can utilize S1 bearer context request message indication eNodeB to set up maximum rate for reserved GBR load, for example, MME is carried at reserved GBR load tabulation and QoS in the S1 bearer context request message, and sends to eNodeB.An object lesson that recovers the S1 interface bearing is: set up the S1 interface bearing according to the QoS in the S1 bearer context request message.

Step 5, eNodeB are that the UE that is in Idle state sets up the wireless side carrying that maximum rate is a non-zero.It is zero wireless side carrying that eNodeB also need set up maximum rate at reserved GBR load.

The maximum rate that step 6, UE can set up according to above-mentioned success is that the wireless side carrying of non-zero sends upstream data.

Step 7, eNodeB send the S1 bearer context request to MME and set up message (also claiming the S1 bearer context request to finish message).

Step 8, MME receive after the S1 bearer context request sets up message, send to Serving GW and upgrade bearing request message, can not successfully set up if there is core-network side to carry corresponding empty port load-supporting, and MME will trigger the carrying dispose procedure so.

If the access technology of step 9 UE changes, then Serving GW sends to PDN GW and upgrades bearing request message.

After step 10, PDN GW receive and upgrade bearing request message, otherwise according to disposed dynamic PCC, by determining the PCC rule of the access technology after the variation with the information interaction of PCRF, determine Qos according to the PCC rule of the access technology after changing again; PDN GW determines Qos according to local Qos strategy.

Step 11, PDN GW send and upgrade bearing response message.

The renewal bearing response message that step 12, Serving GWS-GW will receive is transmitted to MME.

Fig. 3 b shows the service request procedure under the UE initiation connected state that is in connected state.In the service request procedure shown in Fig. 3 b, recover the core-network side carrying of reserved GBR load correspondence, and for that set up, the reserved GBR load correspondence, maximum rate be that zero S1 interface bearing and wireless side carrying are provided with maximum rate.

Among Fig. 3 b, step 1, UE send service request information to MME.Carry cells such as S-TMSI in this service request information.Can also increase in the service request information that UE sends and carry the cell that is used to carry the information relevant with recovering reserved GBR load.The sign of the reserved GBR load that the cell loaded information of this increase can be recovered for needs also can be for recovering the indication information of whole reserved GBR loads.When the cell loaded information that increases during for the sign of the reserved GBR load that needs to recover, this sign can exist with the form of GBR bearing identification tabulation.The indication information that recovers whole reserved GBR loads can be 1 bit indicating bit etc.

MME determines mode that need to recover reserved GBR load to be had multiplely, and when carrying the reserved GBR load tabulation in the service request information that receives at MME, MME determines needs to recover reserved GBR load; Carry the indication information that recovers whole reserved GBR loads and this indication information for another example when representing that needs recover reserved GBR load in the service request information that MME receives, MME determines needs the recovery reserved GBR load; Also have, not carrying the information representation relevant with recovering reserved GBR load in MME in the default service requests message recovers under the situation of whole reserved GBR loads, after MME receives the service request information of not carrying above-mentioned increase cell, search the reserved GBR load that whether has this UE, after finding the reserved GBR load that has this UE, determining needs to recover reserved GBR load.PDN GW determines the specific implementation process of Qos such as the description among the above-mentioned embodiment.

The QoS that upgrades the reserved GBR load that the needs that carry in the bearing request message recover can be the QoS of reserved GBR load when normally moving.In the E-UTRAN environment, for discharge the reserved GBR load that forms owing to the S1 interface, owing to preserve the QoS that maximum rate is reduced to the carrying before zero among the MME, therefore, the QoS when MME can obtain reserved GBR load and normally moves from its canned data.For the maximum rate that passes over from UTRAN is zero carrying, because the QoS that consults when including reserved GBR load in the PDP Context that receives of MME and normally moving, therefore, MME can get access to the QoS of reserved GBR load when normally moving from the PDP Context information that receives.

After step 2c, PDN GW receive the renewal bearing request message that Serving GW sends, obtain and upgrade the recovery reserved GBR load information of carrying in the bearing request message, and the QoS of definite reserved GBR load.PDN GW is provided with the core-network side carrying of reserved GBR load correspondence according to the QoS of the reserved GBR load of determining.

Determine reserved GBR load QoS can for: PDN GW by carrying out information interaction or obtain qos requirement at reserved GBR load according to local collocation strategy with PCRF, then, determine the QoS of reserved GBR load again according to the qos requirement of the concrete condition of current network resources and above-mentioned acquisition.The object lesson of the QoS of a definite reserved GBR load is: reduce to zero reserved GBR load at the maximum rate of coming from the UTRAN band, PDN GW provides a new QoS who is not less than the QoS of former requirement according to the current network resources situation for reserved GBR load.Certainly, here be not less than also can be for being equal to or less than.A concrete example is: PDN GW can will upgrade the QoS that carries in the bearing request message QoS as reserved GBR load, and promptly PDN GW is according to upgrading the core-network side carrying that the QoS that carries in the bearing request message is provided with the reserved GBR load correspondence.Concrete as the description among the above-mentioned embodiment.

Step 2d, PDN GW send and upgrade bearing response message after the core-network side carrying that is provided with the reserved GBR load correspondence, can carry the QoS of the reserved GBR load that successfully recovers in this renewal bearing response message.Upgrade the identification information that also can carry the reserved GBR load that successfully recovers in the bearing response message, tabulate as reserved GBR load.Concrete as the description among the above-mentioned embodiment.The successful recovery here is meant the successful recovery of core-network side carrying.

The renewal bearing response message that step 2e, Serving GW will receive is transmitted to MME, still can carry the QoS of the reserved GBR load that successfully recovers in this renewal bearing response message.To step 4.

Fig. 3 b acceptance of the bid is marked with step 3, and the subscription authentication of step 3 is applied to be in the service request procedure of UE of Idle state, and in the present embodiment, because UE is in connected state, therefore, this step does not need to carry out.

After step 4, MME receive and upgrade bearing response message, from upgrade bearing response message, obtain reserved GBR load tabulation and the QoS information successfully recovered, and to eNodeB transmission S1 bearer context request message (i.e. second Indication message), the maximum rate of revising the reserved GBR load correspondence with indication eNodeB is the QoS that zero S1 carries.Carry QoS in the above-mentioned S1 bearer context request message, this QoS can be for upgrading the QoS that carries in the bearing response message, in addition, can also carry the reserved GBR load tabulation that successfully recovers in this S1 bearer context request message, concrete as the description among the above-mentioned embodiment.

Step 5, eNodeB are wireless side carrying Resources allocation, the modification QoS that successfully recovers the reserved GBR load correspondence of core-network side carrying, to improve the speed of wireless side carrying.Successfully recover the S1 interface bearing and the wireless side carrying of reserved GBR load correspondence by step 4 and step 5.

Step 7, eNodeB send the S1 bearer context to MME and finish message, with the restoration result of notice MME reserved GBR load.The S1 bearer context is finished message bearing bearing identification.This bearing identification such as S1 interface bearing sign etc.

Step 8, MME are receiving after the S1 bearer context finishes message, send to Serving GW and upgrade bearing request message, can not successfully set up if there is core-network side to carry corresponding empty port load-supporting, and MME will trigger the carrying dispose procedure so.

MME in the foregoing description three is after the service request that receives the UE transmission that is in Idle state, by send S1 bearer context request message to eNodeB, make eNodeB can be under the situation of the Idle state of UE be that to set up maximum rate be zero S1 interface bearing and wireless side carrying to reserved GBR load according to this message; MME is after the service request that receives the UE transmission that is in connected state, by send the renewal bearing request message that carries reserved GBR load tabulation and QoS to PDN GW, make PDN GW upgrade the core-network side carrying that bearing request message is recovered the reserved GBR load correspondence according to this; PDN GW is by sending the QoS carry the reserved GBR load that successfully recovers the core-network side carrying and successfully recovering the renewal bearing response message of the reserved GBR load sign of core-network side carrying to MME, make MME upgrade bearing response message according to this and send to eNodeB and carry that the reserved GBR load that successfully recovers the core-network side carrying identifies and the S1 bearer context request message of QoS; ENodeB can will revise the S1 interface bearing of above-mentioned foundation and the maximum rate of wireless side carrying according to the S1 bearer context request message that receives.Thereby in being in the process of Idle state and connected state, UE successfully recovers reserved GBR load.

Embodiment four, UE are in Idle state, and UE initiates the service request procedure under the Idle state, recover the reserved GBR load of UE in the service request procedure of the UE under being in Idle state.The specific implementation process of embodiment four as shown in Figure 4.

Among Fig. 4, step 1, UE send service request information to MME.Carry cells such as S-TMSI in this service request information.

After step 2a, MME received service request information, MME searched the reserved GBR load that whether has this UE in the system, and behind the reserved GBR load of this UE of existence, MME sends and upgrades bearing request message (i.e. first Indication message) in the system of finding.

The QoS of the reserved GBR load that the needs that carry in this renewal bearing request message recover can be the QoS of reserved GBR load when normally moving.In the E-UTRAN environment, for discharge the reserved GBR load that forms owing to the S1 interface, owing to preserve the QoS that maximum rate is reduced to the carrying before zero among the MME, therefore, the QoS when MME can obtain reserved GBR load and normally moves from its canned data.For the maximum rate that passes over from UTRAN is zero carrying, because the QoS that consults when including reserved GBR load in the PDP Context that receives of MME and normally moving, therefore, MME can get access to the QoS of reserved GBR load when normally moving from the PDP Context information that receives.

Determine reserved GBR load QoS can for: PDN GW by carrying out information interaction or obtain qos requirement at reserved GBR load according to local collocation strategy with PCRF, then, determine the QoS of reserved GBR load again according to the qos requirement of the concrete condition of current network resources and above-mentioned acquisition.The object lesson of the QoS of a definite reserved GBR load is: reduce to zero reserved GBR load at the maximum rate of coming from the UTRAN band, PDN GW provides a new QoS who is not less than the QoS of former requirement according to the current network resources situation for reserved GBR load.Certainly, here be not less than also can be for being equal to or less than.A concrete example is: PDN GW also can will upgrade the QoS that carries in the bearing request message QoS as reserved GBR load, and promptly PDN GW is according to upgrading the core-network side carrying that the QoS that carries in the bearing request message is provided with the reserved GBR load correspondence.

Step 2d, PDN GW send and upgrade bearing response message after the core-network side carrying that has recovered the reserved GBR load correspondence, can carry the QoS of the reserved GBR load that successfully recovers in this renewal bearing response message.The successful recovery here is meant the successful recovery of core-network side carrying.Also can carry the identification information of the reserved GBR load that successfully recovers in the above-mentioned renewal bearing response message, tabulate as reserved GBR load.Concrete as the description among the above-mentioned embodiment.

The renewal bearing response message that step 2e, Serving GW will receive is transmitted to MME, still can carry the QoS of the reserved GBR load that successfully recovers in this renewal bearing response message.

Step 3 is carried out the subscription authentication process.

After step 4, MME receive and upgrade bearing response message, from upgrade bearing response message, obtain reserved GBR load tabulation and the QoS information successfully recovered, and, recover the S1 interface bearing of reserved GBR load correspondence with indication eNodeB to eNodeB transmission S1 bearer context request message (i.e. second Indication message).Carry QoS in the above-mentioned S1 bearer context request message, this QoS can be for upgrading the QoS that carries in the bearing response message, in addition, can also carry the reserved GBR load tabulation that successfully recovers in this S1 bearer context request message, concrete as the description among the above-mentioned embodiment.

Step 5, eNodeB are that the reserved GBR load that successfully recovers the core-network side carrying recovers corresponding wireless side carrying.An example that recovers the wireless side carrying is: after successfully setting up the S1 carrying, eNodeB calculates the QoS of the wireless side carrying of reserved GBR load correspondence according to the QoS in the S1 bearer context request message, then, sets up the wireless side carrying according to the QoS that calculates.

MME in the foregoing description four is after the service request that receives the UE transmission that is in Idle state, by send the renewal bearing request message that carries reserved GBR load tabulation and QoS to PDN GW, make PDN GW upgrade the core-network side carrying that bearing request message is recovered the reserved GBR load correspondence according to this; PDN GW is by sending the QoS carry the reserved GBR load that successfully recovers the core-network side carrying and successfully recovering the renewal bearing response message of the reserved GBR load sign of core-network side carrying to MME, make MME upgrade bearing response message according to this and send to eNodeB and carry that the reserved GBR load that successfully recovers the core-network side carrying identifies and the S1 bearer context request message of QoS; ENodeB can recover the S1 interface bearing and the wireless side carrying of reserved GBR load correspondence according to the S1 bearer context request message that receives.Thereby in being in the process of Idle state, UE successfully recovers reserved GBR load.

Embodiment five, UE are in Idle state, UE initiates the service request under the Idle state, in the service request procedure of UE under being in Idle state, MME notice PDN GW recovers reserved GBR load, and PDN GW recovers the reserved GBR load of UE according to the notice of MME, by the dedicated bearer modification process that utilizes modification QoS.The specific implementation process of embodiment five as shown in Figure 5.

Among Fig. 5, step 1, UE send service request information to MME.Carry cells such as S-TMSI in this service request information.

After PDN GW receives the renewal bearing request message that Serving GW sends, determine the quality of service information of the reserved GBR load that needs recover according to the current network resources situation, then, dedicated bearer modification process according to the existing modification of this quality of service information of determining triggering QoS utilizes this bearing modification flow process to recover reserved GBR load.Need to prove, in this bearing modification flow process, if the S1 interface bearing of reserved GBR load correspondence and wireless side carrying are successfully set up, but maximum rate is zero, then need to revise the S1 interface bearing of reserved GBR load correspondence and the QoS of wireless side carrying; If the S1 interface bearing of reserved GBR load correspondence and wireless side carrying are not set up, then need to set up the S1 interface bearing and the wireless side carrying of reserved GBR load correspondence according to QoS.In addition, the detailed process of the quality of service information of the definite reserved GBR load that need recover of PDN GW such as the description among other embodiment no longer describe in detail at this.

In the bearing modification flow process, the S1 interface bearing of the reserved GBR load correspondence that success is set up and wireless side carrying can be S1 interface bearing and the wireless side carryings that utilizes flow process shown in Figure 3 to set up.

Step 2d, PDN GW are sending the renewal bearing response message.

The renewal bearing response message that step 2e, Serving GW will receive is transmitted to MME.

Step 3 is carried out the subscription authentication process.

After step 4, MME receive the renewal bearing response message that Serving GW sends, send S1 bearer context request message to eNodeB, eNodeB recovers the S1 interface bearing with indication.The S1 interface bearing here is at the carrying except that reserved GBR load.

Step 5, eNodeB are that the wireless side carrying is set up in the carrying in the network.

Need to prove, in carrying out this step 5 processes, if the S1 interface bearing of reserved GBR load correspondence is not successfully set up, then eNodeB can set up S1 interface bearing and wireless side carrying for reserved GBR load in this step, like this, behind second Indication message of eNodeB in receiving the bearing modification flow process, eNodeB modification reserved GBR load is correspondence, successful foundation, maximum rate is zero S1 interface bearing and the maximum rate of wireless side carrying.

An example that recovers the wireless side carrying is: eNodeB is after successfully setting up the S1 interface bearing, calculate the QoS of the wireless side carrying of reserved GBR load correspondence according to the QoS in the S1 bearer context request message, then, set up the wireless side carrying according to the QoS that calculates.

Need to prove that in addition present embodiment can be carried out the different implementation procedure of difference generation of sequential according to step.For example, the S1 interface bearing and the wireless side carrying back of recovering the reserved GBR load correspondence are carried out, like this, eNodeB is when receiving S1 bearer context request message, can set up maximum rate earlier is zero S1 interface bearing and wireless side carrying, then, in the S1 interface bearing and wireless side load bearing process that recover the reserved GBR load correspondence, the maximum rate of revising above-mentioned foundation is the zero S1 interface bearing and the QoS of wireless side carrying.Again for example, eNodeB directly sets up the carrying of non-vanishing S1 interface bearing of maximum rate and wireless side after receiving S1 bearer context request message.

Step 7, eNodeB send the S1 bearer context to MME and finish message.This S1 bearer context is finished message bearing and has the EPS carrying tabulation of the EPS carrying tabulation of eNodeB address, acceptance, refusal and S1 TEID (s) (DL) etc.

Step 8, MME are receiving after the S1 bearer context finishes message, send to Serving GW and upgrade bearing request message, can not successfully set up if there is EPS to carry corresponding empty port load-supporting, and MME will trigger the carrying dispose procedure so.

MME in the foregoing description five is after the service request that receives the UE transmission that is in Idle state, by send the renewal bearing request message that carries reserved GBR load tabulation and QoS to PDN GW, make PDN GW upgrade bearing request message and trigger the bearing modification flow process according to this, thus the core-network side carrying, S1 interface bearing and the wireless side carrying that recover the reserved GBR load correspondence; In the bearing modification flow process of embodiment five, can directly set up S1 interface bearing and wireless side carrying according to QoS, also can be that zero S1 interface bearing and wireless side carrying improves the maximum rate processing to the maximum rate that has existed; Thereby in being in the process of Idle state, UE successfully recovers reserved GBR load.

Embodiment six, UE are in connected state, UE initiates the service request under the connected state, in the service request procedure of UE under being in connected state, MME notice PDN GW recovers reserved GBR load, and PDN GW recovers the reserved GBR load of UE according to the notice of MME, by the dedicated bearer modification process that utilizes modification QoS.The specific implementation process of embodiment six as shown in Figure 6.

Among Fig. 6, step 1, UE send service request information to MME.Carry cells such as S-TMSI in this service request information.Can also increase in the service request information that UE sends and carry the cell that is used to carry the information relevant with recovering reserved GBR load.The sign of the reserved GBR load that the cell loaded information of this increase can be recovered for needs also can be for recovering the indication information of whole reserved GBR loads.When the cell loaded information that increases during for the sign of the reserved GBR load that needs to recover, this sign can exist with the form of GBR bearing identification tabulation.The indication information that recovers whole reserved GBR loads can be 1 bit indicating bit etc.

Step 2d, PDN GW are sending the renewal bearing response message to Serving GW.

The renewal bearing response message that step 2e, Serving GW will receive is transmitted to MME, to step 4.

Fig. 6 acceptance of the bid is marked with step 3, and the subscription authentication of step 3 is applied to be in the service request procedure of UE of Idle state, and in the present embodiment, because UE is in connected state, therefore, this step does not need to carry out.

Step 4, after subscription authentication success, MME sends service request to UE and accepts message.

MME in the foregoing description six is after the service request that receives the UE transmission that is in connected state, by send the renewal bearing request message that carries reserved GBR load tabulation and QoS to PDN GW, make PDN GW upgrade bearing request message and trigger the bearing modification flow process according to this, thus the core-network side carrying, S1 interface bearing and the wireless side carrying that recover the reserved GBR load correspondence; In the bearing modification flow process of embodiment six, can directly set up S1 interface bearing and wireless side carrying according to QoS, also can be that zero S1 interface bearing and wireless side carrying improve maximum rate and handle to the maximum rate that has existed, the maximum rate here be that zero S1 interface bearing and wireless side carrying can be to set up in UE is in the process of Idle state; Thereby be in the process of connected state or in UE is in the process of connected state and Idle state, successfully recover reserved GBR load at UE.

Embodiment seven, UE initiating updating of tracking area, in the tracing section updating process that UE initiates, MME notice PDN GW recovers reserved GBR load, and PDN GW recovers the reserved GBR load of UE according to the notice of MME.The specific implementation process of embodiment seven as shown in Figure 7.

Among Fig. 7, step 1, under the situation that satisfies the tracing section updating condition, UE initiating updating of tracking area request message.UE is provided with in the tracing section updating request message under the situation of " Active Flag " sign, can also in the tracing section updating request message, increase cell, the cell of this increase is used to carry the information relevant with recovering reserved GBR load, needs the reserved GBR load that recovers with indication.

Step 2, UE send the tracing section updating request message to eNodeB, can comprise in this tracing section updating request message: oldGUTI, last visited TAI, active flag, cells such as EPS bearer status, P-TMSI Signature.

After step 3, eNodeB receive the tracing section updating request message, this tracing section updating request message is transmitted to MME.

Step 4, caused attached to MME and routing update originally under the situation of MME change at UE, target MME sends context request message to former MME.

After step 5, former MME received context request message, MME returned context response information to target, to step 8.

If UE caused moving under the situation of MME attached to SGSN and routing update originally, then above-mentioned steps 4 and step 5 can replace with following step 6 and step 7.

Step 6, target MME network element send context request message to former SGSN.

After step 7, former SGSN received context request message, MME returned context response information to target, to step 8.

Step 8, UE initiate authentication process.This step is an optional step, and promptly UE can not initiate authentication process.

Step 9, target MME send context acknowledgement message to former MME.

Under the situation of carrying out above-mentioned steps 6 and step 7, above-mentioned steps 9 can replace with following step 10.

Step 10, target MME send context acknowledgement message to former SGSN.

Step 11, do not reselect under the situation of new Serving GW at MME, MME sends to Serving GW network element and upgrades bearing request message.Selected at MME under the situation of new Serving GW, then MME can send to new Serving GW and create bearing request message.

Being provided with " active flag " mark and MME in the tracing section updating request message that MME receives finds under the situation that has reserved GBR load in the system, perhaps MME determines under the situation of the reservation attitude GBR that has the needs recovery according to the cell that increases in the above-mentioned steps 1, MME is to carry first Indication message that recovers reserved GBR load information by Serving GW to renewal bearing request message or the establishment bearing request message that PDN GW sends, and first Indication message is used to indicate PDN GW to recover reserved GBR load.

The renewal bearing request message that MME sends or create can carry the GBR carrying tabulation that needs the reservation attitude recovered and the corresponding QoS of each GBR carrying in the tabulation in the bearing request message, promptly MME utilizes one to upgrade bearing request message or one and create the information that bearing request message sends all reserved GBR loads that need recover.When the reserved GBR load of needs recovery has many, MME also can upgrade bearing request message or many by many and create the information that bearing request message sends needs the reserved GBR load that recovers, for example, one is upgraded bearing request message or one and creates bearing request message and only carry a sign that needs the reserved GBR load that recovers and QoS etc.

The QoS that upgrades bearing request message or create the reserved GBR load that the needs that carry in the bearing request message recover can be the QoS of reserved GBR load when normally moving.In the E-UTRAN environment, for discharge the reserved GBR load that forms owing to the S1 interface, owing to preserve the QoS that maximum rate is reduced to the carrying before zero among the MME, therefore, the QoS when MME can obtain reserved GBR load and normally moves from its canned data.For the maximum rate that passes over from UTRAN is zero carrying, because the QoS that consults when including reserved GBR load in the PDP Context that receives of MME and normally moving, therefore, MME can get access to the QoS of reserved GBR load when normally moving from the PDP Context information that receives.

Need to prove that renewal bearing request message here and establishment bearing request message only are a kind of explanations that exemplifies, the step 11 of present embodiment also can adopt other message, and present embodiment does not limit the message name of concrete employing.

Step 12, Serving GW should upgrade bearing request message and be transmitted to PDN GW after receiving and upgrading bearing request message.

Step 13, PDN GW receive the renewal bearing request message, parse upgrade carry in the bearing request message recover reserved GBR load information after, carry out and recover to keep attitude GBR operation.

The recovery reserved GBR load operation here can have two kinds of different modes:

Mode 1, the definite QoS that needs the reserved GBR load of recovery of PDN GW, for example, PDN GW is by mutual with PCRF or according to the quality of service information that carries in local collocation strategy or transmission comes according to MME the message and consider that mode such as present Internet resources situation determines QoS, recover the core-network side carrying of reserved GBR load correspondence according to this QoS, and QoS sent to MME, make MME indication eNodeB recover the S1 interface bearing and the wireless side carrying of reserved GBR load correspondence.For example, utilize the process that step 2c among the embodiment two describes to step 5 or utilize the process that step 2c among the embodiment three describes to step 5 or utilize the process that step 2b describes to step 5 among the embodiment four to recover reserved GBR load.

Mode 2, PDN GW determine the QoS of the reserved GBR load that needs recover according to present Internet resources situation, and trigger the dedicated bearer modification process of revising QoS, recover reserved GBR load to utilize this bearing modification process.For example, utilize the process that step 2b describes among the embodiment five to recover reserved GBR load.

Step 14, PDN GW send to Serving GW and upgrade bearing response message.If PDN GW adopts mode 1, then PDN GW can increase cell in upgrading bearing response message, this cell is used to carry the reserved GBR load sign of recovery and the QoS of respective carrier, and the reserved GBR load sign can adopt the form of reserved GBR load tabulation.If PDN GW adopts mode 2, then the renewal bearing response message of PDN GW transmission is the message in the existing tracing section updating flow process.

Step 15, Serving GW will upgrade bearing response message and be transmitted to MME after receiving and upgrading bearing response message.If PDN GW adopts mode 1, then still carry the cell that increases newly of the QoS of the reserved GBR load sign that is used to carry recovery and respective carrier in the renewal bearing response message that Serving GW sends, above-mentioned reserved GBR load sign can adopt the form of reserved GBR load tabulation.If PDN GW adopts mode 2, then the renewal bearing response message of Serving GW transmission is the message in the existing tracing section updating flow process.

After step 16, target MME receive and upgrade bearing response message, send the renewal location request message to HSS.

Step 17, HSS send cancel location message to former MME after receiving and upgrading location request message.

Step 18, caused moving under the situation of MME attached to SGSN and routing update originally at UE, former SGSN network element sends Iu to RNC and connects release command.

Step 19, RNC discharge Iu and connect after receiving Iu connection release command, and send Iu connection Release complete to former SGSN.

After step 20, former MME receive cancel location message, return the canceling position acknowledge message to HSS.

Step 21, HSS send renewal position acknowledge message to target MME after receiving the canceling position acknowledge message.

After step 22, target MME receive and upgrade the position acknowledge message, send tracing section updating to UE and accept message.If be provided with " Active Flag " sign in the tracing section updating request message, then this moment S1 interface bearing and wireless side bearing activation.The wireless side carrying is the user plane bearer of wireless side.

Step 23, UE receive after tracing section updating accepts message, send tracing section updating to target MME and finish message.

Embodiment seven is on MME notice PDN GW recovers basis that reserved GBR load and MME change, the corresponding steps of above-mentioned corresponding embodiment is merged in the tracing section updating process, successfully recover reserved GBR load in the tracing section updating process thereby be at UE.

Embodiment eight, UE initiating updating of tracking area, in the tracing section updating process that UE initiates, MME and Serving GW network element all do not change, and MME notice PDN GW recovers reserved GBR load, and PDN GW recovers the reserved GBR load of UE according to the notice of MME.The specific implementation process of embodiment eight as shown in Figure 8.

Among Fig. 8, step 1, under the situation that satisfies the tracing section updating trigger condition, UE triggers the tracing section updating process, UE is provided with in the tracing section updating request message under the situation of " Active Flag " sign, can also in the tracing section updating request message, increase cell, the cell of this increase is used to carry the information relevant with recovering reserved GBR load, needs the reserved GBR load that recovers with indication.

If step 4 UE is in Idle state, then can carry out authentication/security process.

Step 5, be provided with " Active Flag " sign and MME finds under the situation that has reserved GBR load in the system in the tracing section updating request message, MME send to upgrade bearing request message (i.e. first Indication message).

Need to prove that the renewal bearing request message here only is a kind of explanation that exemplifies, the step 5 of present embodiment also can adopt other message, and present embodiment does not limit the message name of concrete employing.

Step 6, Serving GW should upgrade bearing request message and be transmitted to PDN GW after receiving and upgrading bearing request message.

Step 7 or step 7b, PDN GW network element receive and upgrade bearing request message, carry the reserved GBR load information of recovering in the bearing request message if upgrade, and then carry out and recover to keep attitude GBR operation.

The recovery reserved GBR load operation here can have two kinds of different modes, and is concrete as the description among the above-mentioned embodiment seven, in this no longer repeat specification.

Step 8, PDN GW send to Serving GW and upgrade bearing response message.If PDN GW adopts mode 1, then PDN GW can increase cell in upgrading bearing response message, this cell is used to carry the reserved GBR load sign of recovery and the QoS of respective carrier, and the reserved GBR load sign can adopt the form of reserved GBR load tabulation.If PDN GW adopts mode 2, then PDN GW sends and upgrades bearing response message, can not increase above-mentioned cell in this renewal bearing response message.

Step 9, Serving GW will upgrade bearing response message and be transmitted to MME after receiving and upgrading bearing response message.If PDN GW adopts mode 1, then still carry the cell that increases newly of the QoS of the reserved GBR load sign that is used to carry recovery and respective carrier in the renewal bearing response message that Serving GW sends, above-mentioned reserved GBR load sign can adopt the form of reserved GBR load tabulation.If PDN GW adopts mode 2, then can not carry the cell of above-mentioned increase in the renewal bearing response message that Serving GW sends.

After step 10, MME receive and upgrade bearing response message, send tracing section updating to UE and accept message.If be provided with " Active Flag " sign in the tracing section updating request message, then this moment, the carrying of S1 interface bearing and wireless side was activated.

Step 11, UE receive after tracing section updating accepts message, send tracing section updating to target MME and finish message.

Embodiment eight is on MME notice PDN GW recovers basis that reserved GBR load and MME do not change, the corresponding steps of above-mentioned corresponding embodiment is merged in the tracing section updating process, successfully recover reserved GBR load in the tracing section updating process thereby be at UE.
