摘要:
A method for maintaining traffic continuity through a Traffic Offload Function (TOF) entity includes the following steps: the TOF entity receives a downlink packet of offload traffic of a User Equipment (UE), where the downlink packet of the offload traffic is sent by a Packet Data Network (PDN); the TOF entity sends a Core Network (CN) paging message to the UE; the TOF entity receives a paging response sent by the UE to the CN, where the paging response includes a service request message of the UE; and the TOF entity forwards the service request message to the CN so that the CN sets up a Radio Access Bearer (RAB) after the service request message is received. With the method, the communication between the CN and the UE can be restored to guarantee the transmission of traffic. Accordingly, a TOF entity is also disclosed according to the present invention.
