Bearing processing method and device

Abstract

The invention provides a bearing processing method and device. The method comprises the steps of conducting a depth message detection (DPI) on the business flow of a business based on the matching regulation of a preset seven layer protocol type; conducting a shallow message detection SPI on the business flow of a business based on the matching regulation of a preset third or fourth layer protocol type and obtaining a DPI / SPI processing result; determining the business quality property parameter of a business based on the DPI / SPI processing result and the preset matching regulation; judging whether the quality property parameter is the same as the already bearing quality property parameter or not. If the quality property parameter is not the same as the already bearing quality property parameter, a special bearing is established for the business. The device comprises a processing module, a business quality property parameter determining module and a special bearing establishing module. The establishment of the special bearing is realized without PCRF. A special bearing of relative business can be established only through conducting a depth message detection DPI / SPI processing on the business flow of a business and using PDN GW. The variety of special bearing establishing devices is increased.

Description

technical field [0001] The present invention relates to the communication field, in particular to a bearer processing method and device. Background technique [0002] The next-generation core network system architecture evolution SAE includes: mobility management network elements, such as mobility management entity MME or S4GPRS service support node S4 SGSN, responsible for location management, connection management, security authentication, gateway selection, etc. of mobile user terminals; service gateway S -GW is responsible for the local access gateway of the user terminal; the data gateway P-GW is responsible for the gateway for the user terminal to access the external data network; the policy and charging rule function PCRF is the control node of the quality of service QoS and charging policy. In the network architecture of SAE, the policy decision point created according to the dedicated bearer described in 3GPP standard TS 23.401 is defined in the policy server PCRF. ...

Problems solved by technology

Specifically, to create the dedicated bearer, the AF needs to provide relevant parameters of the service to the PCRF, and the PCRF creates the dedicated bearer of the service according to the relevant parameters. However, in the existing policy and charging control PCC deployment scheme, due to various Operators have different deployment methods and ideas. The application function entity AF has no centralized point and is difficult to deploy. As a result, the PCC architecture functions are basically based on static configuration and cannot dynamically perceive services and apply different strategies. This affects the ability of PCRF to create dedicated bearers. Use promotion, and because PCRF creates dedicated bearers based on the relevant parameters reported by AF, if you want to create dedicated bearers through PCRF, you need to deploy AF, which increases the hardware overhead of the system
