METHOD AND EQUIPMENT FOR KEEPING TRAFFIC CONTINUITY THROUGH TRAFFIC OFFLOAD FUNCTION (TOF) ENTITY |
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 service request message includes a Service Type field indicative of the paging response; 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, where the Service Type field in the service request indicates a data content (Data). 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.
