Abstract

A session switching method is characterized in that management equipment receives a session establishment request message from a target gateway, wherein the message carries a user identification; the management equipment determines that the session establishment request carries a switching indication used for indicating that a user access strategy and charging control gateway generates switching, according to the user identification, an existing session between management equipment and a source gateway of the user is searched, session information of the session between the management equipment and the source gateway is transferred to a session between the management equipment and the target gateway; a session establishment response message is sent to the target gateway; and the management equipment receives a switching completion notification message from the target gateway and sends a session termination request message to the source gateway, wherein the switching completion notification message is sent under the condition that the target gateway knows that a downlink data flow of the user is not forwarded through the source gateway. Through the above scheme, a user session switching problem is solved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for session switching. Background technique [0002] The architecture diagram of Policy and Charging Control (PCC) framework is defined in the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP for short), which includes: policy control and charging rule functional entities (Policy Control and Charging Rules Function, PCRF), (Policy and Charging Enforcement Function, PCEF), Online Charging System (Online Charging System, OCS for short), etc. Wherein, the PCRF is mainly used to determine the PCC rule of the user, and send the determined PCC rule to a Policy and Charging Enforcement Function (Policy and Charging Enforcement Function, PCEF). PCEF is generally implemented based on gateways, which can connect to various access networks. [0003] The interface between the PCRF and the PCEF is the Gx interface, throu...
