Traffic diversion between the method and apparatus of a different network

Example discloses a method and apparatus for traffic diversion between a different network of the present invention, by means ANDSF capability negotiation with the user equipment, the user equipment controlled by the network side sending a request to the ANDSF ISRP unit using ANDSF indicating means according to the request generating ISRP after the non-access instruction 3GPP network the non-3GPP access network is also connected to non-3GPP network and the 3GPP network in the UE, and then made according to the ANDSF based unit under ISRP ISRP offload policy request indicates that the user equipment resides in the 3GPP network What business, business which resides in the non-3GPP network. Through the above process can be performed independently ISRP shunt strategy 3GPP network traffic offload, the ability to achieve through negotiation, the purpose of controlling the user equipment is completed by the network side initiates ISRP process, to save resources in the network service distribution process.
