The embodiment of the present invention is applicable to following scene: perform the unloading of selectivity Internet Protocol flow (Selected IP Traffic Offload, SIPTO, Internet Protocol, IP) time, (namely high data flow is required to IP continuity to reduce to flow the IP of particular type, such as voice call, file transfer protocol (FTP) (File Transport Protocol, FTP) download etc.) impact, and not deexcitation is for transmitting the PDN connection of the IP stream of those particular types, connecting from the PDN that the APN that the same SIPTO of having permits is correlated with of terminal is so likely caused to anchor to different PGW, wherein, the IP stream of particular type comprises: long life cycle IP stream (long-lived flows), Real-Time IP stream (real-time flows), wherein, long life cycle IP stream refers to that data transmission period is greater than the IP stream of setting threshold.
Illustrating, for long life cycle IP stream, can be terminal configuration threshold values (as time threshold values T), for arbitrary IP stream of terminal transmission, when terminal determines that this IP flows from starting transmission, still in transmission after elapsed time section T, then determine that this IP flows for long life cycle IP stream;
