Problems solved by technology

However, when a terminal is connected to an ASN, once the ASN becomes abnormal or faulty, the service of the terminal already connected to the ASN will be interrupted, and the re-access of the terminal cannot be realized in a short time

Embodiment Construction

[0079] The main purpose of the present invention is to propose a method for selecting an Access Support Node (ASN) for a terminal in a network with identity and location separation, so that when the access control device in the wireless network is networked in a disaster recovery manner, when When a certain ASN fails to provide services, the access control device can automatically select another ASN, so that the terminal can access the normal ASN and continue to provide services, reducing the time of service interruption due to ASN failure.

[0080] In order to achieve the above purpose, the present invention provides a method for selecting an access gateway device for a terminal. Specifically, the following technical solutions are adopted, and on the premise of no conflict, the technical features in the following solutions can be combined with each other:

[0081] The access control device is connected to multiple access gateway devices at the same time, and the access control...

Abstract

The invention discloses a selecting and disaster tolerant method and a selecting and disaster tolerant system for accessing a supporting node and an access control device. The access control device is connected with a plurality of access gateway devices simultaneously, and corresponding relation of terminal identification and access gateway devices is configured on the access control device. During a terminal access process, the access control device accesses a terminal to the access gateway devices corresponding to the terminal identification according to the corresponding relation of the configured terminal identification and the access gateway devices. The selecting and disaster tolerant method and the selecting and disaster tolerant system for accessing the supporting node and the access control device can be applied to an identification locator separation network, the access control device is connected with a plurality of average sample numbers (ASNs), the plurality of ASNs form a service area. When a certain SAN in the service area is failed and escapes service, other available ASNs or spare ASNs can provide service fast, and service interruption time is reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a selection and disaster recovery method, system and access control equipment of an access support node. Background technique [0002] In the TCP / IP (Transmission Control Protocol / Internet Protocol, Transmission Control Protocol / Internet Protocol) protocol widely used in the existing Internet, the IP address has dual functions, as the position identification of the network interface of the communication terminal host at the network layer in the network topology , which is also used as the identity of the network interface of the transport layer host. At the beginning of the design of the TCP / IP protocol, the situation of host mobility was not considered. However, when host mobility becomes more and more common, the defect of semantic overload of IP addresses becomes more and more obvious. When the IP address of the host changes, not only the route will change, but...
