Step 802, the APN that SGSN provides according to UE (APN, Access Point Name) is for UE selects a suitable core net gateway.SGSN sends PDP to the core net gateway and activates request, wherein carries the UE sign, PDP type, QoS information, parameters such as charge information.If insert general packet radio service (GPRS; General Packet Radio Service) network, then the core net gateway is GGSN, if insert evolution block core (EPC; Evolved Packet Core) network, then the core net gateway refers to SGW and PGW.The network that inserts is different, and interactive messages also can be different between network element, but its effect is similar, describes with the example that is described as that inserts the GRPS network here, it will be appreciated by those skilled in the art that the processing mode in all the other networks is also basic identical.
Step 803, core net gateway are verified the parameter of carrying in the PDP activating request message, and the qos parameter that carries in the request are authorized.
Step 804, the core net gateway returns PDP to SGSN and activates response, wherein carries the tunnel end sign of distributing into UE, information such as the qos parameter of mandate.
Step 805, SGSN sends the load-bearing allocation request to the base station, wherein carries the Mobile Subscriber International ISDN Number of UE, APN, information such as qos parameter.
Step 806, if the qos parameter that the core net gateway issues has been accepted in the base station, then the process that Radio Resource control (RRC, Radio Resource Control) connects foundation is initiated in the base station.
Step 807, RAB (RAB, Radio Access Bear) assignment response message is returned to SGSN in the base station.If set up many carryings simultaneously, then a plurality of RAN assignment response messages can be returned in the base station.
Step 808, if the qos parameter in the RAB assignment message can't be accepted in the base station, then SGSN is given in indication in the RAN assignment response message that returns.SGSN indicates according to this, can select to issue new qos parameter.
Step 809, SGSN judges whether that according to whether setting up direct tunnel send PDP to the core net gateway upgrades request, if send, then wherein carries the tunnel end sign of base station.If the QoS that the preceding with it core net gateway of QoS issues is inconsistent, then SGSN is through PDP renewal process notice core net gateway.
Step 810, SGSN sends PDP to UE and activates response message.
UE can pass through certain base station access network, but according to different data distribution strategies, data flow possibly a part flow out through the core net network, and a part is shunted away through local gateway.In above-mentioned framework; In order to reduce influence to gateway architecture; Avoid introducing the influence of local gateway as far as possible, especially, dispose the cost expense that this function is brought thereby practice thrift operator to the influence of base station to other network elements in the existing framework; Therefore base station and the not perception of core net gateway are positioned at the local gateway on the data path; Thereby the qos parameter that causes core net gateway and base station to be controlled is inconsistent, and especially when the streamed data amount was bigger, excessive data possibly cause the data of core net to be affected even packet loss.

Step 1010, if the qos parameter in the RAB assignment request message can't be accepted in the base station, then SGSN is given in indication in the RAN assignment response message that returns.Optional, the TOF entity is intercepted and captured this message, and whether recording carrying sets up success.
Step 1011, the TOF entity is transmitted RAB assignment response message SGSN to SGSN and is indicated according to this, can select to issue new qos parameter.
If follow-up SGSN has issued new RAB assignment request message, then the TOF entity still need be intercepted and captured and handle according to the processing mode of step 1006.
Step 1012, SGSN judges whether that according to whether setting up direct tunnel send PDP to the core net gateway upgrades request, if send, then wherein carries the tunnel end sign of base station.If the QoS that the preceding with it core net gateway of QoS issues is inconsistent, then SGSN is through PDP renewal process notice core net gateway.
Step 1013, SGSN sends PDP to UE and revises response message.
This flow process is applicable to that the PDP that PDP revises, SGSN initiates that UE initiates revises, and the PDP that GGSN initiates revises, the PDP modification process that HLR/HSS initiates.
Local gateway was revised the flow chart of the processing mode one of QoS parameter when Figure 11 the present invention inserted the EPC network, and shown in figure 11, this execution mode does not limit base station type, and promptly the base station can be Home eNodeB or ordinary base station.Being example with the base station during flow process is described, is identical to the influence of Home eNodeB.This execution mode goes for the situation that UTRAN/EUTRAN inserts the EPC network.Insert for UTRAN/GERAN, mobile management net element refers to SGSN; Insert for EUTRAN, mobile management net element refers to MME.The core net gateway refers to the SGW/PGW that is positioned at core net.Local gateway can be TOF entity or NAT gateway in this embodiment, but realizes that function class seemingly.Present embodiment inserts the EPC network with ETURAN, and the base station is an ordinary base station, and local gateway is that example describes for the NAT gateway.For the base station is the scene of Home eNodeB, possibly have femto gateway in the network, and when having femto gateway, the message between all Home eNodeB and the mobile management net element all need be passed through femto gateway and transmitted and get final product.Further, the message between Home eNodeB and the local gateway can not sent through femto gateway through femto gateway yet.For the scene of transmitting message through femto gateway, femto gateway carries out transparent transmission to the message of process and gets final product.
Shown in figure 11, the handling process of local gateway modification QoS parameter specifically may further comprise the steps when the present invention inserted the EPC network:
Step 1101, subscriber equipment are initiated PDN and are connected the request of foundation, and this non-access layer information sends to MME via the base station.
Step 1102, the APN that MME provides according to UE is for UE selects a suitable core net gateway.MME creates conversation request to sending to PGW through SGW, wherein carries the UE sign, PDN type, the QoS information that UE is signatory, parameters such as charge information.
Step 1103, the PGW gateway is verified creating the parameter of carrying in the conversation request message, and the signatory qos parameter that carries in the request is authorized.
Step 1104, PGW returns to MME through SGW and creates conversational response message, wherein carries the tunnel end sign of distributing into UE, information such as the qos parameter of mandate.
Step 1105; MME judges whether to allow UE to set up local access service (including but not limited to that local IP access service or selected IP shunt professional) according to the CAMEL-Subscription-Information of UE and/or the APN information of UE request connection; Send the UE initial context to the base station and set up request message, perhaps RAB sets up request message.The sign of wherein carrying UE (includes but not limited to Mobile Subscriber International ISDN Number/IMSI/S-TMSI of UE, and/or APN, and/or qos parameter, and/or the charging characteristic parameter, and/or whether allows to set up information such as local connection.Optional wherein also need carry signatory QoS parameter, includes but not limited to the MBR of UE.Also carry the default bearing that need pass through UE in this message and activated request.
Whether send UE initial context request message, perhaps RAB sets up request message, be to be that UE has set up the S1 connection according to MME.Set up the S1 connection between MME and the base station, then issued RAB and set up request, otherwise issue the request of UE initial context.What above-mentioned two message were carried relates to content class of the present invention seemingly, and Rule of judgment is a prior art.
Step 1106; Local gateway is intercepted and captured the UE initial context request message that MME sends, and perhaps RAB sets up request message, according to the MSISDN that comprises in carrier policy judgement and the message; APN and/or charging characteristic information; And/or whether allow to set up local the connection, whether judgement will be with all carrying, and some data in perhaps carrying are shunted.Local gateway is according to the data characteristic of selected shunting, confirms the QoS parameter that streamed data needs, comprising but be not limited to Maximum Bit Rate, QoS parameters such as RAB symmetry indication (be used to indicate up-downgoing data whether symmetry).Local gateway is revised UE initial context request message according to the QoS parameter of streamed data, and perhaps RAB sets up the QoS parameter in the request message.If optional step 1105 has issued signatory QoS parameter, then require amended QoS parameter can not run counter to signatory QoS parameter.The process of revising is that example describes with the Maximum Bit Rate; UE initial context request message, perhaps to set up the Maximum Bit Rate in the request message be A to RAB, if issue the signatory Maximum Bit Rate of UE in the optional step 1105; Be assumed to be B; Local gateway has confirmed that the Maximum Bit Rate of streamed data is C, the then amended UE initial context of local gateway request, and Maximum Bit Rate was A+C during perhaps RAB set up and asks.Local gateway requires C<B-A in the Maximum Bit Rate of confirming streamed data.
Local gateway need be preserved the request of former UE initial context, and perhaps RAB sets up the QoS parameter that carries in the request, and amended QoS parameter.
Local gateway also need be revised the default bearing that MME need pass through UE and activate the QoS parameter in the request, and the QoS parameter of modification is with above-mentioned consistent.
The UE initial context request that step 1107, local gateway will be revised, perhaps the RAB request of setting up sends to the base station.
Step 1108, if the qos parameter that the core net gateway issues has been accepted in the base station, then the process that RRC connects foundation is initiated in the base station.Otherwise the base station refusal carries the request of foundation.
Step 1109, the response of UE initial context is returned to MME in the base station, and perhaps RAB sets up response message.
Step 1110, optional, local gateway is intercepted and captured this message, and whether recording carrying sets up success.Local gateway is transmitted to MME.The response of UE initial context, perhaps RAB sets up response message.
Step 1111, UE returns default bearing through the base station to MME and activates response.Optional, local gateway is intercepted and captured this message, and whether recording carrying sets up success.
Step 1112, MME send to upgrade load bearing process to SGW, and the tunnel end sign of base station is sent to SGW.
This process is applicable to PDN establishment of connection in the attach process that UE initiates, and is applicable to that also independent PDN connects the process of setting up.
