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

Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] Such as figure 2 As shown, in one embodiment, a method for controlling access is proposed, the method includes:

[0044] Step 202, the PSG receives the user access message, obtains the control chain path information according to the user access message, extracts the user information according to the control chain path information, and sends the control chain path information and user information to the control chain node.

[0045] In this embodiment, the user access message carries user information, and a feature in the user information is extracted to uniquely match a control link path in...

Abstract

Embodiments of the present invention provide an access control method and system. The method comprises: a packet domain gateway receives a user access message, acquires control link path information, extracts user information according to the control link path information, and sends the user information to a control link node; the control link node performs control according to the received user information, and sends a control result indicative of success control and the user information to a next control link node; and the packet domain gateway receives the control result returned by the control link node, and controls a user access according to the control result. By implementing a control link in a packet domain core network, frequent signaling interaction during access control is reduced, and network bandwidths are increased; and meanwhile, by decoupling a packet domain gateway from a control link node, the difficulty of implementation is reduced, and the expandability of deployment of a new service is improved. Besides, also provided are an access control method and 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), AAAServer (Authentication, Authorization and Accounting Server, authentication, authorization and accounting server) and other surrounding network elements establish new PDN c...
