Problems solved by technology

Since the DRA as a proxy node is not the actual maintainer of the session, without knowing whether the current session information is valid, it only relies on experience to set the time to delete the session information. If the valid session binding information is deleted by mistake, it will cause business failure
In addition, after deleting the session information, the actual maintainer PCEF of the session is not notified. Such a session processing method needs to be improved urgently.

Abstract

The invention discloses a session information processing method, device and system, wherein the method comprises the following steps of: setting a timer having pre-set time for current session information; after the pre-set time is up, sending a request for auditing the current session information; receiving a response for auditing the current session information; on the basis of the response, obtaining an effective state or an ineffective state of the current session information, and refreshing the timer when the current session information is in the effective state, so that the request for auditing the current session information is re-sent when the pre-set time is up again; and, when the current session information is in the ineffective state, deleting the current session information. Thereby, by means of the embodiment, the ineffective session information can be deleted accurately in time; therefore, the system overhead is reduced; the operation speed is increased; the information processing reliability is improved; and the application range is enlarged.

Description

technical field [0001] The invention belongs to the technical field of network communication, and in particular relates to a processing method, device and system for session information. Background technique [0002] In the PCC (Policy Control and Charging, policy control and charging) architecture, PGW (PacketGateway, packet array gateway) and PCRF (Policy and Charging Rule Function, policy and charging rule functional unit) establish IP-CAN ( IP-Connectivity Access Network, IP link access network) session, execute policy control. PCEF (Policy and Charging Enforcement Function, policy and charging enforcement unit) executes the policy and charging issued by PCRF. Usually, the PCEF is located at the PGW gateway or the GGSN gateway, and of course it can also be deployed independently. The DRA (Diameter Router Agent, routing agent node) as an intermediate node can be used to transfer and process the PCC session information between the PCEF and the PCRF. At present, in order...
