Application flow detection method, entity and system

Abstract

Embodiments of the present invention provide an application flow detection method, entity and system. The method includes: the control entity receives the application flow; the control entity simultaneously matches the application flow with at least one corresponding processing rule, and determines the first processing rule with the highest priority among the processing rules that are successfully matched within a time length; The control entity sends the application flow information corresponding to the first processing rule to the Policy and Charging Rules Function PCRF entity. It can ensure that only reported high-priority processing rules successfully match the application flow information corresponding to the application flow, so as to reduce the signaling interaction load and effectively avoid the deviation of application flow policy control execution.

Description

technical field [0001] The present invention relates to the communication field, in particular to an application flow detection method, entity and system. Background technique [0002] With the development of mobile broadband network technology, more and more mobile terminals, such as smart phones and tablet computers, are flooding the mobile broadband network with application interactions. Different applications have different application characteristic information, such as: IP address and port information of the application server, application layer protocol name information used by the application or URL address information of the application, and so on. Only after the operator network detects these application flow information, can it execute different policy control operations for different applications, for example: provide differentiated quality of service (QoS, Quality of Service) guarantees for different applications, or provide different applications with Implemen...

AI Technical Summary

Problems solved by technology

If PCEF reports unnecessary application flow information to PCRF, it will not only increase the signaling interaction load between PCEF and PCRF entities, but also, for multiple application flow information received, PCRF cannot further determine which application flow information to use The PCC rule execution operation corresponding to the information leads to the deviation of application flow policy control execution
