Control access method and system, and gateway

Abstract

The invention provides a control access method and system. The method comprises: a packet domain gateway receives a user access message, obtains control chain path information, extracts the user information according to the control chain path information, and sends the user information to a control chain node; the control chain node carries out controlling based on the received user information, sends a control result with successful controlling and the user information to a next control chain node; and the packet domain gateway receives the control result returned by the control chain node and controls user access according to the control result. According to the method provided by the invention, because a control chain is realized in a packet domain core network, frequent signaling interaction during access control can be reduced and the network bandwidth is increased. Meanwhile, on the basis of decoupling of the packet domain gateway and the control chain node, realization difficulty can be reduced and scalability for new business deployment can be improved. In addition, the invention also provides a control access system and a gateway.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a control access method, system and gateway. Background technique [0002] Under the framework of 3GPP (3rd Generation Partnership Program, the third generation cooperation project), the evolved packet domain gateway is located between the wireless domain and the PDN (Packet Date Network, packet data network) domain. When the terminal uses the packet domain service, the packet domain gateway Establish a PDN connection for the terminal, trigger the business process of the Gx, Gy, Ga, Raius and other interfaces related to the PDN, and notify PCRF (Policy and Charging Rules Function, policy and charging functional unit), OCS (Online Charging System, online charging system ), CG (Charging Gateway), AAA Server (Authentication, Authorization and Accounting Server, authentication, authorization and accounting server) and other peripheral network elements to establish new P...

AI Technical Summary

Problems solved by technology

This method of controlling according to the static configuration order is likely to cause complex implementation of the packet domain gateway, heavy load, frequent interaction, and excessive intra-domain signaling, resulting in waste of bandwidth resources. When new control network elements are added, it is difficult to expand, and it is easy to cause impact on existing network users
