Description
Technical field
The present invention relates to the communications field, particularly relate to method and target-high-speed packet data service gateway and the terminal of flow unloading.
Background technology
EHRPD (evolvedHighRatePacketData, the high-speed packet network of evolution) network support is linked into EPC (evolvedpacketcore, the packet-based core networks of evolution) network, it accesses gateway is HSGW (HRPDServingGateway, high-speed packet data service gateway)；HSGW is by providing MAG (mobileaccessgateway, Mobile Access Gateway) function with support with PGW (PacketDataNetworkGateway, grouped data network gateway) between mobility, and then realize eHRPD Access Network and dispose with the networking of a kind of believable non-3 gpp (3rdGenerationPartnershipProject, third generation partner program) network insertion EPC network.
Along with the fast development of data service, SIPTO (SelectedIPTrafficOffload, selected IP flow unloading) function also obtains the extensive concern of 3GPP operator gradually.SIPTO is mainly used in reducing operator's transmission cost, alleviates core net pressure.
At present, 3GPP2 (3rdGenerationPartnershipProject2, third generation partner program 2) also formulate the SIPTO technical specification for eHRPD network, make UE (UserEquipment, terminal) when mobile, still can select geographical position/network topology and access PGW access network nearest for HSGW, it is achieved the demand that certain types of flow is unloaded by operator nearby.
The 3GPP2SIPTO technology specified in 3GPP2X.S0057-Bv1.0 agreement, it is necessary to UE supports SIPTO function.In current protocol specification, it is achieved method is as follows:
If UE supports at VSNCP (VendorSpecificNetworkControlProtocol, manufacturer's particular network control protocol) configuration terminates carrying in request message reconnecting instruction config option and this option value for " reconnecting this APN (AccessPointName; APN) ", then UE should carry in the VSNCP configuration request message when just establishing APN " SIPTO supports config option ", and this option is set to 1, represent and support SIPTO function；
When UE moves and occurs to switch across HSGW, new service HSGW the PDN (PacketDataNetwork, packet data network) of certain or certain several APN may be connected be redirected on geographical position or network topology closer to PGW on.If HSGW thinks to have redirects PDN necessity connected and terminal support SIPTO function, then can actively send VSNCP and terminate request message to UE, and the value reconnecting instruction config option carried within the message is " APN reconnecting this request ".Subsequently, UE initializes the APN, the HSGW that need to reconnect and reselects new PGW in this flow process.
Accompanying drawing 1 is the schematic flow sheet of prior art Plays 3GPP2SIPTO function:
Step 101, T-HSGW to UE send VSNCP terminate request message, and carry within the message reconnect instruction config option value be " APN reconnecting this request ".
Step S102, UE return VSNCP to HSGW and terminate response message.
Step S103-S104, T-HSGW send PBU message (lifetime=0) to S-PGW, notify its release resource；PGW replys PBA message subsequently.
Step S105, UE reinitialize needs the APN that reconnects, in the process of this reconnect, HSGW select in geographical position or network topology closer to PGW, set up PDN and connect.
By above flow process it is found that the deployment of 3GPP2SIPTO function depends on the support of UE, during actual deployment, there is certain limitation.
