Method and device for formulating business chain strategy

Abstract

An embodiment of the present invention provides a method for formulating a service chain policy, including: the unit PCRF receives the first message sent by the AS via the SCEF, the first message is used to request a service chain policy for the service flow of the UE, and the first message including the service chain requirement of the service flow; the PCRF formulates a service chain strategy for the service flow according to the service chain requirement of the service flow included in the first message, and the service chain strategy includes The service chain function provided by the service flow. In the technical solution provided by the embodiments of the present invention, when a user needs to perform a certain service, the PCRF formulates a service chain strategy suitable for the service flow according to the message sent by the AS and contains the service flow requirements corresponding to the service, which is different from that of the user in the prior art. Compared with formulating the business chain policy when attaching to the network and before specifying the specific business to be executed, the formulating method of the business chain policy is more flexible, so that more accurate and efficient business chain rules can be formulated.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method and equipment for formulating a service chain strategy. Background technique [0002] The 3rd generation partnership project (3GPP, 3rd generation partnership project) constructs the SAE system architecture in the system architecture evolution (SAE, system architecture evolution) project. Wherein, at least one service function enabler unit can be deployed between the operator gateway and the external network to form a service chain. [0003] In fields such as mobile, fixed broadband and data center applications, there is at least one value-added service requirement for a specific service flow of a specific user. Each value-added business service requirement corresponds to at least one business function enabling unit. For example, the video service flow needs to pass through the service chain formed by the service function enabling units corresponding to ...

AI Technical Summary

Problems solved by technology

In fact, when a user uses a specific service, the service enabling unit that the service flow of the specific service needs to pass through may not be included in the service chain policy determined when the user attaches to the network, or the service chain policy includes the specific The business enabling unit that is not required by the business flow, obviously, such a business chain strategy formulation method is not accurate and flexible enough
