Embodiment

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

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

Step 1, MME receive the message relevant to terminal.

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

When the message relevant to terminal is the message of terminal transmission, can carry the information relevant with recovering reserved GBR load in this message.The reserved GBR load list that the 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 to the reserved GBR load of above-mentioned terminal be recovered.

The information that MME carries in can the message relevant to terminal according to its reception is determined needs the reserved GBR load of terminal is recovered; For example, the reserved GBR load list that recovers according to the needs that carry in 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 message recovers etc. the reserved GBR load of terminal.

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

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

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

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

Mode one, for E-UTRAN, reduce to quality of service information before zero owing to storing reserved GBR load speed in MME, therefore, MME can obtain from its canned data needs quality of service information corresponding to reserved GBR load that recover.

Mode two, for UTRAN, can receive due to MME the PDP Context information that carries quality of service information, therefore, MME can obtain quality of service information corresponding to reserved GBR load that need to recover from the PDP Context information that it receives.

The first Indication message that MME sends can transfer to by the gateway of intermediate equipment such as terminal PDN GW.Under there was more news in the gateway of terminal, MME can be sent to PDN GW with the 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 in the situation that be that terminal selects new gateway, and MME sends to PDN GW by the current gateway of terminal and carries the first Indication message that recovers reserved GBR load information; MME is in the situation that selected new gateway for terminal, and MME is by carrying for the new gateway of selecting of terminal sends to PDN GW the first Indication message that recovers reserved GBR load information.

PDN GW determines the quality of service information of this reserved GBR load after receiving the 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 with PCRF the quality of service requirement that information interaction obtains this reserved GBR load, 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; PDN GW obtains the quality of service information requirement of this reserved GBR load according to local collocation strategy for another example, and requires 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 the 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 the first Indication message and current network resources situation.Need to prove, PDN GW also can adopt alternate manner to determine the quality of service information of reserved GBR load, and the embodiment of the present 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 in the situation that the real network resource allows according to the quality of service information that carries in the 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 the first Indication message for reserved GBR load; In the situation that the real network resource allows, distribute the service quality of carrying in the first Indication message for reserved GBR load for another example; Also have in the unallowed situation of real network resource, distribute quality of service information lower than the quality of service information that carries in the first Indication message etc. for reserved GBR load.The embodiment of the present invention does not limit PDN GW and determines the specific implementation process of the quality of service information of reserved GBR load according to the quality of service information that carries in the first Indication message and current network resources situation.

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, recovering core-network side carrying corresponding to above-mentioned reserved GBR load according to this quality of service information of determining, is namely core-network side carrying Resources allocation corresponding to reserved GBR load according to this quality of service information of determining.For example, according to the maximum rate of determining, core-network side carrying corresponding to reserved GBR load is set.

PDN GW returns to response message for the first Indication message to MME after having recovered core-network side carrying corresponding to reserved GBR load.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, it can be the quality of service information that MME obtains from this response message that above-mentioned MME is sent to the quality of service information that carries in the second Indication message of base station.Certainly, the quality of service information that carries in the second Indication message can be also the quality of service information that MME adopts alternate manner to obtain, for example, and the quality of service information that target MME obtains from switching former end.

In addition, PDN GW is after receiving the 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 core-network side carrying corresponding to above-mentioned reserved GBR load.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 that reserved GBR load is corresponding.Utilize the above-mentioned bearing modification flow process that is triggered to recover reserved GBR load corresponding S1 interface bearing and wireless side carrying.The specific implementation process of utilizing the bearing modification flow process to recover core-network side carrying corresponding to reserved GBR load and S1 interface bearing and wireless side carrying can for existing implementation procedure, be not described in detail at this.Need to prove, if PDN GW triggers the bearing modification flow process, the 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 in the bearing modification flow process, MME sends as the second Indication message.The quality of service information that carries in the second Indication message can only comprise maximum rate, certainly, also can comprise maximum rate and out of Memory.

The base station is after the second Indication message that receives the MME transmission, in the situation that the reserved GBR load that exist to need recovers corresponding, maximum rate is 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 direct maximum rate that S1 interface bearing and wireless side carrying are set according to the quality of service information in the second Indication message, namely direct maximum rate with S1 interface bearing and wireless side carrying is nonzero value by zero adjustment; In the situation that do not exist reserved GBR load corresponding, maximum rate is zero S1 interface bearing and wireless side carrying, S1 interface bearing corresponding to the reserved GBR load that need to recover and the process of setting up of wireless side carrying need to be carried out in the base station, then the maximum rate of S1 interface bearing and wireless side carrying is set according to the quality of service information in the second Indication message then.

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

Successfully set up when the base station receives the second Indication message, 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 corresponding to reserved GBR load of indication base station foundation 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 in following embodiment that MME indicates the base station to set up maximum rate.

Need to prove, in the description of above-described embodiment one, MME can first send the first Indication message, then sends the second Indication message; MME also can first send the second Indication message, then sends the first Indication message.The different sending orders of the first Indication message, the second Indication message exemplify description in the following embodiments.

From the description of above-described embodiment one as can be known, embodiment one triggers PDN GW by MME to recover core-network side carrying corresponding to reserved GBR load, and trigger the base station by MME and recover S1 interface bearing corresponding to reserved GBR load and wireless side carrying, thereby successfully recovered reserved GBR load.

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, UE first initiates a service request procedure under Idle state 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.

In Fig. 2, step 1, the UE that is in connected state send service request information to MME.Carry the cells such as S-TMSI in this service request information.Can also increase the cell that carries for the carrying information relevant with recovering reserved GBR load in the service request information that UE sends.The sign of the reserved GBR load that the information of the cell of this increase carrying can be recovered for needs also can be for recovering the indication information of whole reserved GBR loads.During for the sign of the reserved GBR load that needs to recover, this sign can exist with the form of GBR bearing identification list when the information of the cell carrying that increases.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 to be in each network equipment clear.If do not require the recovery reserved GBR load in the service request procedure of the terminal that is in connected state, can recover reserved GBR load in other process, for example, when UE need to 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 MME sends and upgrades bearing request message (i.e. the first Indication message).

MME determines mode that need to recover reserved GBR load to be had multiplely, and when carrying the reserved GBR load list in the service request information that receives at MME, MME determines needs to recover reserved GBR load; When carrying for another example the indication information that recovers whole reserved GBR loads and this indication information 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, do not represent to recover whole reserved GBR loads in the situation that carry the information relevant with recovering reserved GBR load in MME in default service requests message, 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 GBR carrying list of the reservation attitude that needs recovery and QoS corresponding to each GBR carrying in list in the renewal bearing request message that MME sends, namely MME utilizes one to upgrade the information that bearing request message sends all reserved GBR loads that need to 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 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 due to the S1 interface, due to the QoS that preserves maximum rate in MME and reduce to the carrying before zero, therefore, the QoS when MME can obtain reserved GBR load and normally moves from its canned data.Be that zero carrying (is that UE is under the UTRAN environment for the maximum rate that passes over from UTRAN, having maximum rate is zero carrying, afterwards, UE moves to the E-UTRAN environment from the UTRAN environment, the QoS that consults when including reserved GBR load in the PDP Context of UE under former UTRAN environment that receives due to MME and normally moving, QoS when therefore, MME can get reserved GBR load and normally moves from the PDP Context information that received in the past.

Need to prove, the renewal bearing request message here is only a kind of explanation that exemplifies, and the step 2a of the present embodiment also can adopt other message, and the 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 forwards and recover reserved GBR load information, as carry reserved GBR load list and QoS, carry for another example reserved GBR load sign and QoS.

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 bearing request message of upgrading, and need to determine the QoS of the reserved GBR load that recovers.PDN GW arranges core-network side carrying corresponding to reserved GBR load according to the QoS of the reserved GBR load of determining.

The QoS of the reserved GBR load that determine to need recovers can be for: PDN GW by carrying out information interaction or obtain qos requirement for reserved GBR load according to local collocation strategy with PCRF, then determine the QoS of reserved GBR load according to the qos requirement of the concrete condition of current network resources and above-mentioned acquisition then.The object lesson of the QoS of another definite reserved GBR load that need to recover is: reduce to zero reserved GBR load for 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 refers to 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 in the situation that the QoS that the current network resources situation will be carried in allowing to upgrade bearing request message as the QoS of reserved GBR load, namely in the situation that the current network resources situation allows PDN GW according to the QoS that carries in upgrading bearing request message, core-network side corresponding to reserved GBR load to be set carries.

Step 2d, PDN GW are after being provided with core-network side carrying corresponding to reserved GBR load, send and upgrade bearing response message, can carry the QoS of the reserved GBR load that successfully recovers and the list that successfully recovers reserved GBR load in this renewal bearing response message.The successful recovery here refers to 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 list 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 list of the reserved GBR load that successfully recovers, and when successful recovered part reserved GBR load, can carry the list 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 list that can not carry the reserved GBR load that successfully recovers.Above-mentioned description for carrying the list that successfully recovers reserved GBR load in the renewal bearing response message also is applicable in following corresponding embodiment, no longer repeat specification in the following embodiments.

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 list 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. the second Indication message) to eNodeB after receiving and upgrading bearing response message, recover the S1 carrying take indication eNodeB as the reserved GBR load that successfully recovers the core-network side carrying.Carry QoS in S1 bearer context request message, this QoS is for upgrading the QoS that carries in bearing response message.Can also carry the reserved GBR load identification information that successfully recovers the core-network side carrying in S1 bearer context request message, this identification information is for upgrading the identification information that carries in bearing response message.An object lesson that recovers the S1 interface bearing is: set up the S1 interface bearing according to the QoS in 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 wireless side carrying corresponding to reserved GBR load according to the QoS in S1 bearer context request message, then, set up the wireless side carrying according to the QoS that calculates.Successfully recover S1 interface bearing corresponding to reserved GBR load and wireless side carrying 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 complete message, with the restoration result of notice MME reserved GBR load.

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

MME in above-described embodiment 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 list and QoS to PDN GW, make PDN GW upgrade bearing request message according to this and recover core-network side carrying corresponding to reserved GBR load; 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 S1 interface bearing corresponding to reserved GBR load and wireless side carrying 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 first initiates the service request procedure under Idle state, set up in this service request procedure reserved GBR load corresponding, maximum rate is zero S1 interface bearing and wireless side carrying.After this service request procedure was completed, UE was in connected state.The UE that is in connected state initiates the connected state service request procedure again, carries and be modified in the maximum rate of Idle state foundation as the QoS of zero S1 interface bearing and wireless side carrying to recover core-network side corresponding to reserved GBR load, improves maximum rate.The specific implementation process of embodiment three is as 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.Set up in the service request procedure shown in Fig. 3 a reserved GBR load corresponding, maximum rate is zero S1 interface bearing and wireless side carrying.

In Fig. 3 a, step 1, the UE that is in Idle state send service request information to MME, carry the 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 list and QoS in 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 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 non-zero.It is zero wireless side carrying that eNodeB also need to set up maximum rate for 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 complete message).

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

If the access technology of step 9 UE changes, 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 configured dynamic PCC, by determining the PCC rule of the access technology after variation with the information interaction of PCRF, then determine Qos according to the PCC rule of the access technology after changing; 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.Recover core-network side carrying corresponding to reserved GBR load in the service request procedure shown in Fig. 3 b, and for that set up, that reserved GBR load is corresponding, maximum rate be that zero S1 interface bearing and wireless side carrying arrange maximum rate.

In Fig. 3 b, step 1, UE send service request information to MME.Carry the cells such as S-TMSI in this service request information.Can also increase the cell that carries for the carrying information relevant with recovering reserved GBR load in the service request information that UE sends.The sign of the reserved GBR load that the information of the cell of this increase carrying can be recovered for needs also can be for recovering the indication information of whole reserved GBR loads.During for the sign of the reserved GBR load that needs to recover, this sign can exist with the form of GBR bearing identification list when the information of the cell carrying that increases.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 list in the service request information that receives at MME, MME determines needs to recover reserved GBR load; When carrying for another example the indication information that recovers whole reserved GBR loads and this indication information 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, do not represent to recover whole reserved GBR loads in the situation that carry the information relevant with recovering reserved GBR load in MME in default service requests message, 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 in above-mentioned embodiment.

The QoS that upgrades the reserved GBR load that the needs that carry in 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 due to the S1 interface, due to the QoS that preserves maximum rate in MME and reduce to the carrying before zero, therefore, the QoS when MME can obtain reserved GBR load and normally moves from its canned data.Be zero carrying for the maximum rate that passes over from UTRAN, the QoS that consults when including reserved GBR load in the PDP Context that receives due to MME and normally moving, QoS when therefore, MME can get reserved GBR load and normally moves 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 bearing request message, and the QoS of definite reserved GBR load.PDN GW arranges core-network side carrying corresponding to reserved GBR load according to the QoS of the reserved GBR load of determining.

The QoS that determines reserved GBR load can be for: PDN GW by carrying out information interaction or obtain qos requirement for reserved GBR load according to local collocation strategy with PCRF, then determine the QoS of reserved GBR load according to the qos requirement of the concrete condition of current network resources and above-mentioned acquisition then.The object lesson of the QoS of a definite reserved GBR load is: reduce to zero reserved GBR load for 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 namely PDN GW arranges core-network side carrying corresponding to reserved GBR load according to upgrading the QoS that carries in bearing request message.Concrete as the description in above-mentioned embodiment.

Step 2d, PDN GW send and upgrade bearing response message after being provided with core-network side carrying corresponding to reserved GBR load, 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 bearing response message, as the reserved GBR load list.Concrete as the description in above-mentioned embodiment.The successful recovery here refers to 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, obtain reserved GBR load list and the QoS information of successfully recovering from upgrade bearing response message, and send S1 bearer context request message (i.e. the second Indication message) to eNodeB, revise maximum rate corresponding to reserved GBR load as the QoS of zero S1 carrying take indication eNodeB.Carry QoS in above-mentioned S1 bearer context request message, this QoS can be for upgrading the QoS that carries in bearing response message, in addition, can also carry the reserved GBR load list that successfully recovers in this S1 bearer context request message, concrete as the description in above-mentioned embodiment.

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

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

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

MME in above-described embodiment 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 the eNodeB can be in the situation that the Idle state of UE is 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 list and QoS to PDN GW, make PDN GW upgrade bearing request message according to this and recover core-network side carrying corresponding to reserved GBR load; 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 an 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.

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

After step 2a, MME receive service request information, whether have the reserved GBR load of this UE in the MME seeking system, have the reserved GBR load of this UE in finding system after, MME sends and upgrades bearing request message (i.e. the first Indication message).

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 due to the S1 interface, due to the QoS that preserves maximum rate in MME and reduce to the carrying before zero, therefore, the QoS when MME can obtain reserved GBR load and normally moves from its canned data.Be zero carrying for the maximum rate that passes over from UTRAN, the QoS that consults when including reserved GBR load in the PDP Context that receives due to MME and normally moving, QoS when therefore, MME can get reserved GBR load and normally moves from the PDP Context information that receives.

The QoS that determines reserved GBR load can be for: PDN GW by carrying out information interaction or obtain qos requirement for reserved GBR load according to local collocation strategy with PCRF, then determine the QoS of reserved GBR load according to the qos requirement of the concrete condition of current network resources and above-mentioned acquisition then.The object lesson of the QoS of a definite reserved GBR load is: reduce to zero reserved GBR load for 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 namely PDN GW arranges core-network side carrying corresponding to reserved GBR load according to upgrading the QoS that carries in bearing request message.

Step 2d, PDN GW send and upgrade bearing response message after having recovered core-network side carrying corresponding to reserved GBR load, can carry the successfully QoS of the reserved GBR load of recovery in this renewals bearing response message.The successful recovery here refers to the successful recovery of core-network side carrying.Also can carry the identification information of the reserved GBR load that successfully recovers in above-mentioned renewal bearing response message, as the reserved GBR load list.Concrete as the description in 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, obtain reserved GBR load list and the QoS information of successfully recovering from upgrade bearing response message, and sending S1 bearer context request message (i.e. the second Indication message) to eNodeB, eNodeB recovers S1 interface bearing corresponding to reserved GBR load with indication.Carry QoS in above-mentioned S1 bearer context request message, this QoS can be for upgrading the QoS that carries in bearing response message, in addition, can also carry the reserved GBR load list that successfully recovers in this S1 bearer context request message, concrete as the description in 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 wireless side carrying corresponding to reserved GBR load according to the QoS in S1 bearer context request message, then, set up the wireless side carrying according to the QoS that calculates.

MME in above-described embodiment 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 list and QoS to PDN GW, make PDN GW upgrade bearing request message according to this and recover core-network side carrying corresponding to reserved GBR load; 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 S1 interface bearing corresponding to reserved GBR load and wireless side carrying 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 Idle state, in the service request procedure of UE under being in Idle state, MME notice PDN GW recovers reserved GBR load, PDN GW according to the notice of MME, revise the reserved GBR load of the dedicated bearer modification process recovery UE of QoS by utilization.The specific implementation process of embodiment five as shown in Figure 5.

In Fig. 5, step 1, UE send service request information to MME.Carry the 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, trigger the dedicated bearer modification process of existing modification QoS according to this quality of service information of determining, utilize this bearing modification flow process to recover reserved GBR load.Need to prove, in this bearing modification flow process, if the S1 interface bearing that reserved GBR load is corresponding and wireless side carrying are successfully set up, but maximum rate is zero, need to revise the QoS of S1 interface bearing corresponding to reserved GBR load and wireless side carrying; If the S1 interface bearing that reserved GBR load is corresponding and wireless side carrying are not set up, need to set up S1 interface bearing corresponding to reserved GBR load and wireless side carrying according to QoS.In addition, the detailed process of the quality of service information of the definite reserved GBR load that need to recover of PDN GW such as the description in other embodiment no longer describe in detail at this.

In the bearing modification flow process, the S1 interface bearing that the reserved GBR load that success is set up is corresponding 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 for the carrying except reserved GBR load.

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

Need to prove, in carrying out this step 5 processes, if the S1 interface bearing that reserved GBR load is corresponding is not successfully set up, eNodeB can set up S1 interface bearing and wireless side carrying for reserved GBR load in this step, like this, after second Indication message of eNodeB in receiving the bearing modification flow process, eNodeB modification reserved GBR load is corresponding, 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 wireless side carrying corresponding to reserved GBR load according to the QoS in S1 bearer context request message, then, set up the wireless side carrying according to the QoS that calculates.

Need to prove in addition, the present embodiment can be carried out according to step the different implementation procedure of difference generation of sequential.For example, can make and recover to carry out after S1 interface bearing corresponding to reserved GBR load and wireless side carrying, like this, eNodeB is when receiving S1 bearer context request message, can first set up maximum rate is zero S1 interface bearing and wireless side carrying, then, in recovering reserved GBR load corresponding S1 interface bearing and wireless side load bearing process, the maximum rate of revising above-mentioned foundation is zero S1 interface bearing and the QoS of wireless side carrying.Again for example, eNodeB directly sets up the carrying of the 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 complete message.This S1 bearer context is completed message bearing and has the EPS carrying list of the EPS carrying list of eNodeB address, acceptance, refusal and S1 TEID (s) (DL) etc.

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

MME in above-described embodiment 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 list and QoS to PDN GW, make PDN GW upgrade bearing request message according to this and trigger the bearing modification flow process, thereby recover core-network side carrying corresponding to reserved GBR load, S1 interface bearing and wireless side carrying; In the bearing modification flow process of embodiment five, can directly set up S1 interface bearing and wireless side carrying according to QoS, can be also 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 connected state, in the service request procedure of UE under being in connected state, MME notice PDN GW recovers reserved GBR load, PDN GW according to the notice of MME, revise the reserved GBR load of the dedicated bearer modification process recovery UE of QoS by utilization.The specific implementation process of embodiment six as shown in Figure 6.

In Fig. 6, step 1, UE send service request information to MME.Carry the cells such as S-TMSI in this service request information.Can also increase the cell that carries for the carrying information relevant with recovering reserved GBR load in the service request information that UE sends.The sign of the reserved GBR load that the information of the cell of this increase carrying can be recovered for needs also can be for recovering the indication information of whole reserved GBR loads.During for the sign of the reserved GBR load that needs to recover, this sign can exist with the form of GBR bearing identification list when the information of the cell carrying that increases.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 above-described embodiment 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 list and QoS to PDN GW, make PDN GW upgrade bearing request message according to this and trigger the bearing modification flow process, thereby recover core-network side carrying corresponding to reserved GBR load, S1 interface bearing and wireless side carrying; In the bearing modification flow process of embodiment six, can directly set up S1 interface bearing and wireless side carrying according to QoS, can be also that zero S1 interface bearing and wireless side carrying improve maximum rate and process 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 successfully recover reserved GBR load in UE is in the process of connected state and Idle state 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.

In Fig. 7, step 1, in the situation that satisfy the tracing section updating condition, UE initiating updating of tracking area request message.UE is in the situation that be provided with " Active Flag " sign in the tracing section updating request message, can also increase cell in the tracing section updating request message, the cell of this increase is used for the carrying 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, the 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 the MME change in the situation that UE is attached to MME and routing update originally, target MME sends context request message to former MME.

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

If UE was attached to SGSN originally and routing update causes moving in the situation of MME, 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 to context response information to target, to step 8.

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

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

In the situation that carry 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, in the situation that MME does not reselect new Serving GW, MME send to upgrade bearing request message to Serving GW network element.In the situation that MME has selected new Serving GW, MME can send to new Serving GW and create bearing request message.

In the situation that be provided with " active flag " mark in the tracing section updating request message that MME receives and there is reserved GBR load in MME in finding system, perhaps MME determines in the situation of the reservation attitude GBR that has the needs recovery according to the cell that increases in above-mentioned steps 1, MME is to carry the 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 the first Indication message is used to indicate PDN GW and recovers reserved GBR load.

The renewal bearing request message that MME sends or create can carry the GBR carrying list that needs the reservation attitude recovered and QoS corresponding to each GBR carrying in list in bearing request message, namely 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 to 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 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 due to the S1 interface, due to the QoS that preserves maximum rate in MME and reduce to the carrying before zero, therefore, the QoS when MME can obtain reserved GBR load and normally moves from its canned data.Be zero carrying for the maximum rate that passes over from UTRAN, the QoS that consults when including reserved GBR load in the PDP Context that receives due to MME and normally moving, QoS when therefore, MME can get reserved GBR load and normally moves from the PDP Context information that receives.

Need to prove, the renewal bearing request message here and establishment bearing request message are only a kind of explanations that exemplifies, and the step 11 of the present embodiment also can adopt other message, and the 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, carry recovery reserved GBR load information in parsing the renewal bearing request message after, carry out recovery reservation attitude GBR and operate.

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 message and consider that the mode such as present Internet resources situation determines QoS, recover core-network side carrying corresponding to reserved GBR load according to this QoS, and QoS is sent to MME, make MME indication eNodeB recover S1 interface bearing corresponding to reserved GBR load and wireless side carrying.For example, utilize the process that step 2c in embodiment two describes to step 5 or utilize the process that step 2c in embodiment three describes to step 5 or utilize the process that in embodiment four, step 2b describes to step 5 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 in embodiment five, step 2b describes to recover reserved GBR load.

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

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

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

Step 18, in the situation that UE was attached to SGSN originally and routing update causes moving to MME, former SGSN network element sends the order of Iu Connection Release to RNC.

After step 19, RNC receive the order of Iu Connection Release, discharge Iu and connect, and complete message to former SGSN transmission Iu Connection Release.

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

Step 21, HSS send to target MME and upgrade the position acknowledge message 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, this moment S1 interface bearing and wireless side bearing activation.The wireless side carrying is the user plane bearer of wireless side.

After step 23, UE receive tracing section updating and accept message, send tracing section updating to target MME and complete 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.

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

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

Step 5, in the situation that be provided with " Active Flag " sign in the tracing section updating request message and there is reserved GBR load in MME in finding system, MME sends and upgrades bearing request message (i.e. the first Indication message).

Need to prove, the renewal bearing request message here is only a kind of explanation that exemplifies, and the step 5 of the present embodiment also can adopt other message, and the 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 if upgrade the reserved GBR load information of recovering in bearing request message, 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 in above-mentioned embodiment seven, is not repeated.

Step 8, PDN GW send to Serving GW and upgrade bearing response message.If PDN GW adopts mode 1, PDN GW can increase cell in upgrading bearing response message, this cell is used for the reserved GBR load sign of carrying recovery and the QoS of respective carrier, and the reserved GBR load sign can adopt the form of reserved GBR load list.If PDN GW adopts mode 2, 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, still carry the cell that newly increases for the QoS of the reserved GBR load sign of carrying 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 list.If PDN GW adopts mode 2, 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, this moment, the carrying of S1 interface bearing and wireless side was activated.

After step 11, UE receive tracing section updating and accept message, send tracing section updating to target MME and complete 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.

Embodiment nine, UE switch to E-UTRAN from UTRAN, are that reserved GBR load is set up S1 interface bearing and wireless side carrying in handoff preparation phase, recover core-network side carrying corresponding to reserved GBR load in handover execution stage.The specific implementation process of embodiment nine is as shown in Fig. 9 a and 9b.

The flow chart of the handoff preparation phase when Fig. 9 a shows UE and switches to EUTRAN from UTRAN.In handoff preparation phase, the up-downgoing data are normal transmission still.In addition, when not adopting direct pass-through mode to transmit the up-downgoing data, can adopt the mode of SGSN forwarding data.

In Fig. 9 a, step 1, UE initiate handoff procedure.

Step 2, former RNC send RELOCATION REQUEST message to former SGSN.
