Embodiment Construction

[0046]It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0047] The main solution of the embodiment of the present invention is: when the PCRF entity satisfies the preset race condition and receives the first re-authorization response carrying the preset error code sent by the PCEF entity, cancel the re-sending operation of the re-authorization request; send The first update credit control response carrying the same preset error code is sent to the PCEF entity, and the first update credit control request retransmitted by the PCEF entity based on the first update credit control response is received; based on the bearer information carried in the first update credit control request and Re-decision operation is performed on the service information, and the second update credit control response carrying the decision result is sent to the PCEF entity, thereby avoiding the re...

Abstract

The invention discloses a race condition release method, which includes: when the preset race condition is met and the first re-authorization response carrying a preset error code sent by the policy and charging enforcement function PCEF entity is received, canceling the re-authorization Authorize the resend operation of the request; send the first update credit control response carrying the preset error code to the PCEF entity, and receive the first update credit control request resent by the PCEF entity based on the first update credit control response; based on the first update credit control response The bearer information and service information carried in the control request perform a re-decision operation, and send the second updated credit control response carrying the decision result to the PCEF entity. The invention also discloses a policy and charging rule function PCRF entity, a computer-readable storage medium and a race condition release system. The invention can ensure the accuracy of the decision-making result when the race condition is resolved, and at the same time reduce the system complexity between the PCRF entity and the PCEF entity and the message load between the systems.

Description

technical field [0001] The invention relates to the field of communication technologies, and in particular, to a PCRF entity, a storage medium, a race condition cancellation method and a system for a policy and charging rule function. Background technique [0002] In the prior art, a Policy and Charging Rules Function (Policy and Charging Rules Function, hereinafter referred to as PCRF) entity is mainly responsible for formulating policies and charging rules, and a Policy and Control Enforcement Function (Policy and Control Enforcement Function, hereinafter referred to as PCEF) )entity. When a session is established between the PCRF entity and the PCEF entity, and a race condition for session resource update occurs in the session, in order to break the race condition of waiting for each other, the current solution is: when a race condition occurs, the PCEF entity replies with the specified The error code reauthorization response is sent to the PCRF entity, and the PCRF enti...
