PCRF entity, storage medium, race condition release method and system

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.
