Problems solved by technology

[0004] However, when DRA1 and DRA2 belong to different manufacturers, DRA1 and DRA2 cannot communicate through the private interface, that is, DRA1 cannot send the corresponding relationship between IMSI, user IP address and PCRF to DRA2 through the private Rx interface messages, and the corresponding relationship between IMSI, user IP address and PCRF to determine the PCRF bound to DRA1, resulting in the inability of the PCC session to be bound to the same PCRF, thus making it impossible to bind DRA2 and DRA1 to the same PCRF

Abstract

The invention discloses a session binding method and a network system in an embodiment and relates to the technical field of communications. The session binding method is capable of realizing the binding of DRA2 and DRA1 to the same PCRF. The method of the embodiment comprises the following steps: the first DRA receives a response message sent by the PCRF, wherein the response message carries PCRF binding information; the first DRA obtains the PCRF binding information and stores the PCRF binding information in a first database; the first DRA sends a data synchronization request message to the second DRA via a data transmission channel, wherein the data synchronization request carries the PCRF binding information; and the second DRA saves the PCRF binding information so that the second DRA can be bound to the PCRF according to the PCRF binding information. The session binding method is suitable for a network system.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a session binding method and a network system. Background technique [0002] With the development of communication technology, in order to improve the accuracy of addressing, PCC (Policy and Charging Control, policy and charging control) sessions of the same user on different interfaces are usually bound to the same PCRF (Policy and Charging Rules Function, policy and charging rule functional entities). Among them, the PCC session can implement service control and charging. Currently, a method for binding PCC sessions of the same user on different interfaces to the same PCRF is as follows: [0003] When PCEF (PolicyandChargingEnforcementFunction, policy and charging enforcement function entity) sends a Gx interface message carrying IMSI (InternationalMobileSubscriberIdentificationNumber, International Mobile Subscriber Identification Number) and user IP (InternetProtocol,...
