Service link selection control method and device

Abstract

The invention discloses a service link selection control method and device. The service link selection control method comprises the steps that a service link selection strategy sent by a coordinated device is received, wherein the service link selection strategy comprises the corresponding relation among first strategy contextual information, a first application type and a first service link, the first service link is a path composed of a forward device and a value added service device by which first service flow needs to pass, the first service flow comes from a user matched with the first strategy contextual information, and the type of the first service flow is the first application type; a PCRF unit receives the first strategy contextual information, and a service link selection control strategy is determined according to the first strategy contextual information and the service link selection strategy, wherein the service link selection control strategy comprises the corresponding relation between the first application type and the first service link; the PCRF unit sends the service link selection control strategy to a flow classifier. According to the service link selection control method, unnecessary devices can be prevented from being passed by.

Description

technical field [0001] The present application relates to the communication field, in particular to a service link selection control method and equipment. Background technique [0002] In the existing technology, such as figure 1 As shown, a large number of value-added service devices are often connected in series between the access device 110 and the Internet, including: anti-virus device 120, application cache and acceleration device 130, firewall 140, and Network Address Translation (NAT, Network Address Translation) device 150 etc. After the user terminal accesses the network through the access device 110 , the generated data must pass through the antivirus device 120 , the application cache and acceleration device 130 , the firewall 140 and the network address translation device 150 in sequence. In actual use, some users may only sign up for antivirus services, while others may only need NAT. However, under existing technical conditions, all must pass through the ant...

AI Technical Summary

Problems solved by technology

However, under the existing technical conditions, the antivirus device 120, the application cache and acceleration device 130, the firewall 140, and the network address translation device 150 must be sequentially passed through.

This causes these devices to increase unnecessary traffic burden
