METHOD FOR TRIGGERING DATA OFFLOAD, NETWORK-SIDE DEVICE, USER EQUIPMENT, AND NETWORK SYSTEM

摘要

Embodiments of the present invention provide a method for triggering data offload. The method includes: receiving, by a first network element from a home subscriber server HSS, information of a packet data network PDN connection, where the information includes offload indication information, and the PDN connection is established by a UE through a second access network; and obtaining, by the first network element, the offload indication information, and triggering, according to the offload indication information, processing of offloading a data flow in the PDN connection to a first access network. In the foregoing provided solution, the UE does not need to indicate, to the first network element, information that offloading is required for the PDN connection, and therefore the UE does not need to support an IKEv2 protocol. This lowers a requirement of the foregoing offload technology on the UE.

主权项

1. A method for triggering data offload, comprising:
receiving, by a first network element from a home subscriber server (HSS), information of a packet data network (PDN) connection that is established by a UE through a second access network, wherein the information of the PDN connection comprises offload indication information; and triggering, according to the offload indication information, offloading a data flow associated with the PDN connection to a first access network.
