Introduce the concrete Application Example 1 of method attachment flow in the SAE system of embodiment one below.In the SAE system, if the service that the user need use the SAE system to provide, the user at first needs in the middle of the system of being registered to, and the process of this registration can be called as the process that the user is attached to network.In the attaching process of SAE system, according to the control mode decision information, carry out every UE AMBR control if desired, the AMBR that then needs the information of the AMBR that every UE is relevant to send to UE-AMBR carries out functional entity; The control of the AMBR of every APN if desired, then need will be in the attaching process information of AMBR of the acquiescence APN AMBR that sends to APN-AMBR carry out functional entity.Specifically as shown in Figure 3:
Among Fig. 3, step 1 is in 2, and UE initiates to adhere to request, and eNodeB adheres to request with this and is forwarded to MME.
Step 3 is in 4, and after the execution safety inspection, MME asks the user contracting data of this UE to HSS.
In the step 5, HSS returns in the subscription data of MME, has comprised the relevant CAMEL-Subscription-Information of AMBR; HSS sends to MME with the content of this CAMEL-Subscription-Information, but send mode can limit, and can also can utilize new message by existing message.
Wherein, the CAMEL-Subscription-Information storage organization of AMBR among the HSS, can be as shown in the table, but of particular note, scheme in this form can not limit embodiment of the invention applicable scope, promptly this form not perhaps in some system still, can not think thus that the technical scheme in the embodiment of the invention can not be applicable to these systems.
| The AMBR of the every UE of field description UE Id UE sign AMBR control mode AMBR control mode UE-AMBR is corresponding to the AMBR of each signatory every APN of APN:APN APN sign/title APN-AMBR |
MME indicates CAMEL-Subscription-Information and/or draws the AMBR control mode by other system information according to operator's configuration and/or AMBR control mode according to the information that obtains.Wherein, if the control mode of operator configuration information indication is different with the control mode that the user contracts, operator configuration information has higher priority so.For example: the controlling party indication information of the signatory AMBR of user's formula is per APN, but the operator configuration information indication network adopts the control mode of per UE, and MME will be provided with the control mode of per UE for this user so.
If MME can not draw the control mode of user AMBR according to configuration information, then should comprise AMBR control mode indication information in this subscription data; If the control mode of AMBR is per UE, then this CAMEL-Subscription-Information should comprise UE-AMBR; If the control mode of AMBR is per APN or per UE per APN, then should comprise APN-AMBR information in this CAMEL-Subscription-Information; If the control mode of AMBR is per UE per APN, then should comprise UE-AMBR in this CAMEL-Subscription-Information, perhaps, draw UE-AMBR according to pre-configured algorithm, as: by APN-AMBR being added and drawing UE-AMBR, i.e. UE-AMBR=∑ (APN-AMBR).
After judging, MME has obtained the relevant CAMEL-Subscription-Information of AMBR.Wherein, about the AMBR structure information storage, can in MME, need to store the user about the subscription data of AMBR and the relevant parameter that in follow-up flow process, needs among the MME for shown in the following table lattice about AMBR, as: the UE-AMBR that calculates according to APN-AMBR.If control mode is per UE or per UE perAPN, then need be in UE rank storage UE-AMBR information; If control mode is per APN or per UE per APN, then need be at APN rank storage APN-AMBR.Thus, in follow-up flow process, MME sends to corresponding AMBR execution functional entity with the information of AMBR.
| The signatory APN of AMBR information respective user of field description UE Id UE sign AMBR control mode AMBR control mode UE-AMBR UE should comprise: the PDN of corresponding each APN of the AMBR information of APN APN sign/title APN-AMBR APN connects and comprises: this PDN of APN in use connects the carrying that corresponding each PDN of employed APN connects: EPS bearerID carrying RAB sign |
In the step 6, after MME determines the AMBR control mode, send default bearing to S-GW and set up request.
If the AMBR control mode is per UE or per UE per APN, then set up in the request and carry the UE-AMBR parameter at default bearing, be used for carrying out functional entity (S-GW) and do descending control at UE-AMBRAMBR.
If the AMBR control mode is per APN or per UE per APN, then sets up and carry the APN-AMBR parameter in the request message at default bearing.
After S-GW receives default bearing and sets up request, obtain the AMBR relevant information, S-GW can be for shown in the following table lattice about the storage organization of AMBR:
| Field description |
| The AMBR information of field description UE Id UE sign AMBR control mode AMBR control mode UE-AMBR UE connects for each PDN: ... every carrying corresponding to each PDN connection: EPS bearerId bearing identification |
In the step 7, S-GW sends default bearing to P-GW and sets up request.
If control mode is per UE or per UE per APN, then set up in the request and carry the UE-AMBR parameter at default bearing, and UE-AMBR need send to PCRF and do PCC (Policyand Charging Control, the strategy and the control of chargeing) decision-making, and next execution in step 8.
If control mode is per APN or per UE per APN, then set up in the request and carry the APN-AMBR parameter at default bearing, be used for carrying out functional entity (P-GW) and carry out descending control at the AMBR of APN-AMBR, and APN-AMBR need send to PCRF and do the PCC decision-making, and next execution in step 8.
P-GW obtains the AMBR relevant information after receiving default bearing foundation request, and P-GW can need to prove about the storage organization of AMBR P-GW can select whether to store UE-AMBR or AMBR control mode according to specific implementation for shown in the following table lattice.
| The APN that the AMBR information respective user of field description UE Id UE sign AMBR control mode AMBR control mode UE-AMBR UE activates should comprise: |
| The PDN of corresponding each APN of the AMBR information of field description APN APN sign/title APN-AMBR APN connects and comprises: this PDN of APN in use connects the carrying that corresponding each PDN of employed APN connects: EPS bearer ID carrying RAB sign |
Annotate: RAB is Radio Access Bearer, RAB.
Alternatively, mutual by PCRF in the step 8, PCRF makes the PCC decision-making.
Step 9 is returned carrying and is set up corresponding in 10.
In the step 11, MME sends and adheres to acceptance to eNB.
Wherein, if control mode is per UE or per UE per APN, then in adhering to acceptance, carry the UE-AMBR parameter is UE-AMBR to eNB upload control.
If control mode is per APN or per UE per APN, then in adhering to acceptance, need to carry the APN-AMBR parameter is APN-AMBR to eNB upload control.
Wherein, if control mode is per APN or per UE per APN, then in this message, comprise the APN sign, be used for the carrying of current non-GBR is associated with an APN (if control mode is per UE UL per APN DL, then can not set up this incidence relation), finish the upload control of APN-AMBR.
If control mode is per UE per APN, then in adhering to acceptance, comprise UE-AMBR and APN-AMBR parameter, at first guarantee upload control at eNB to per APN, under the prerequisite that guarantees APN-AMBR control, guarantee the upload control of UE-AMBR, finish the dual AMBR control of per UE per APN.
ENB obtains the AMBR relevant information after receiving and adhering to acceptance, and the data store organisation on eNB can be as shown in the table:
| The AMBR of field description UE Id UE sign AMBR control mode AMBR control mode UE-AMBR UE identifies corresponding to the RAB:RAB ID RAB of each APN corresponding to the AMBR of the APN:APN APN sign/title APN-AMBR APN of each activation |
Step 12 connects and reshuffles by RRC (Radio Resource Control, Radio Resource control) in 16, and this UE finishes and adheres to, bearer update.
Present embodiment passes through said process, carry out at needs under the control mode of UE-AMBR, the relevant information of UE-AMBR is sent to UE-AMBR in attaching process AMBR carries out functional entity, and carries out the controlled function that functional entity begins to carry out UE-AMBR at AMBR; Carry out at needs under the control mode of APN-AMBR, the relevant information of the APN-AMBR of acquiescence APN is sent to APN-AMBR in attaching process AMBR carries out functional entity, and carries out the controlled function that functional entity begins to carry out APN-AMBR at AMBR.
The method of introducing embodiment one below in the SAE system, concrete Application Example 2 when UE initiates article one PDN connection building process of APN.Need carry out data transport services with the PDN network if the user has used, at first need to connect with the PDN network, promptly PDN connects.Each PDN connects the default bearing that comprises a non-GBR at least, for realize PDN connect in the AMBR control of non-GBR carrying, concrete grammar as shown in Figure 4:
In the step 1, UE initiates PDN and connects the request of foundation.
In the step 2, MME receives the PDN request of connect setting up, because MME has preserved the AMBR subscription data of this UE in attachment flow, at this moment, MME can carry out follow-up flow process according to the control mode of the AMBR of this UE.
If determine that the AMBR control mode is per APN or per UE per APN, because current flow process is to activate first PDN connection of new APN, be different from the APN that activates in the attachment flow, carry the APN-AMBR parameter so need set up in the request, and send to S-GW at default bearing.
If determine that the AMBR control mode is per UE, then in attachment flow, finished the AMBR control of interdependent node and disposed, do not need to reinform S-GW this moment.
In the step 3, S-GW transmits this message to P-GW after receiving that default bearing is set up request.
If the APN-AMBR parameter is carried in the default bearing that S-GW the receives request of setting up, then transmit and also carry the APN-AMBR parameter in this message to P-GW.
Alternatively, in the step 4, after P-GW received that default bearing is set up request, execution in step 4 alternatively.
Particularly, if control mode is per UE or per UE per APN, and UE-AMBR need send to PCRF and do PCC decision-making, and then PGW need send UE-AMBR to PCRF.If control mode is per APN or per UE per APN, and APN-AMBR need send to PCRF and do PCC decision-making, and then PGW need send APN-AMBR to PCRF.
Step 5 is returned default bearing and is set up response in 6.
In the step 7, MME receives default bearing foundation response, sends carrying foundation to eNB and asks, and this message can be contained in the S1_MME control messages.
If control mode is per APN or per UE per APN, because current flow process is first PDN connection that sets up for APN, reason need need to carry the APN-AMBR parameter is APN-AMBR to eNB upload control with described in the present embodiment step 2 in the S1_MME control messages; For the APN under the identification carrying in eNB, need to carry the APN sign in this message, be used for setting up the related of carrying and affiliated APN, finish APN-AMBR and control.
Step 8 is reshuffled by the RRC connection in 12, and this UE sets up carrying.
Present embodiment passes through said process, when UE and PDN network are set up article one PDN and are connected, the AMBR that the relevant information that this PDN is connected the AMBR of corresponding A PN sends to APN-AMBR carries out functional entity, and AMBR carry out functional entity begin to carry out this PDN connect under the controlled function of APN-AMBR of APN.

In the step 2, MME receives the PDN request of connect setting up, because MME has preserved the AMBR subscription data of this UE in attachment flow, at this moment, MME can carry out follow-up flow process according to the control mode of the AMBR of this UE.
If the AMBR control mode is per APN or per UE per APN, the APN that current flow process connects for existing PDN sets up PDN and connects, if the AMBR of APN-AMBR carries out functional entity and stores APN-AMBR information, then setting up at default bearing does not need to carry the APN-AMBR parameter in the request message, otherwise need carry APN-AMBR information in this message.
In the step 7, MME receives default bearing foundation response, sends carrying foundation to eNB and asks, and this message can be contained in the S1_MME control messages.
If control mode is per APN or per UE per APN, current flow process is to connect for the APN that has the PDN connection sets up PDN, if store APN-AMBR information at eNB, then in the S1_MME control messages, do not need to carry the APN-AMBR parameter, otherwise in this message, need to transmit again APN-AMBR is APN-AMBR to eNB upload control;
For the APN under the identification carrying in eNB, need to carry the APN sign in this message, be used for setting up the related of carrying and affiliated APN, finish APN-AMBR and control.
