Embodiment Construction

[0078] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0079] The present invention provides a method for traffic unloading, referring to figure 2 , figure 2 The flow chart of realizing the 3GPP2SIPTO function for the HSGW agent of the embodiment of the present invention includes the following steps:

[0080] In step S201, the T-HSGW sends a HI (Handover Initiate, handover initiation) message to the S-HSGW, triggering the context transfer from the S-HSGW to the T-HSGW.

[0081] In step 202, the S-HSGW sends a Hack (Handover Ack, Handover Response) message to the T-HSGW to transfer the context information of the UE to the T-HSGW, and the message carries information about PDN connections of all APNs.

[0082] In steps S203-S204, the T-HSGW identifies the APN to be offloaded, and sends a PBU message (lifetime=0) to the S-PGW to notify it to release resources; the PGW the...

Abstract

The invention discloses a traffic offload method. The method comprises following steps of obtaining the packet data network PDN connection information of all access point names APNs; identifying APNs with to-be-offloaded traffics according to the obtained PDN connection information of all APNs; according to the APNs with to-be-offloaded traffics, carrying out vendor specific network control protocol VSNCP re-negotiation with a piece of user equipment UE; sending a VSNCP configuration response to the UE, thus finishing VSNCP re-negotiation and realizing traffic offloading of the APNs with to-be-offloaded traffics. The invention also discloses a target-high rate data packet serving gateway and a terminal. According to the method, the gateway and the terminal, no matter the UE supports a 3GPP2SIPTO (3rd Generation Partnership Project 2 Selected IP Traffic Offload) function or not, the VSNCP re-negotiation of the specific APNs can be triggered, and further the traffic offload function based on the APNs can be realized.

Description

technical field [0001] The present invention relates to the communication field, in particular to a flow unloading method and target-a high-speed packet data service gateway and a terminal. Background technique [0002] The eHRPD (evolvedHighRatePacketData, evolved high-speed packet network) network supports access to the EPC (evolvedpacketcore, evolved packet core network) network, and its access gateway is HSGW (HRPDServingGateway, high-speed packet data service gateway); HSGW provides MAG (mobileaccessgateway, Mobile access gateway) function to support mobility with PGW (Packet Data Network Gateway, packet data network gateway), and then realize eHRPD access network as a trusted non-3GPP (3rdGenerationPartnershipProject, third generation partnership project) network access Network deployment into the EPC network. [0003] With the rapid development of data services, the SIPTO (SelectedIPTrafficOffload, selected IP traffic offload) function has gradually received extensiv...
