ims fixed terminal, management server, nomadic control method and system

Abstract

The invention relates to an IMS (IP multimedia subsystem) fixed terminal roaming control method. The method includes: a terminal management server receives a registration request message sent by a fixed terminal; information of a region corresponding to the IP (internet protocol) address of the fixed terminal is inquired according to the registration request message; the terminal management server inquires the corresponding access SBC (session border control) address according to the region information to form a configuration file; the configuration file is distributed to the fixed terminal to enable the fixed terminal to send a core network registration request to a corresponding SBC device; the core network registration request is transmitted to an IMS core network device by means of signaling and media agency by the SBC device; and roaming control and / or charging operations are performed by the IMS core network device according to a PANI (P-access-network-info) network identification automatically added by the SBC device. By the IMS fixed terminal roaming control method, the problem of acquisition of visit place SBC addresses of the fixed terminal is solved, so that the nearby access of the fixed terminal at visit places can be realized, the problem of poor service quality due to non-nearby access is avoided, roaming control of the fixed terminal is realized, and service operation and charging operation are facilitated.

Description

technical field [0001] The present invention relates to the technical field of Internet and telecommunications, and in particular to an IP Multimedia Subsystem (IP Multimedia Subsystem, IMS for short) fixed terminal, management server, nomadic control method and system. Background technique [0002] With the increasingly mature and stable IMS network technology, some operators have started the pilot construction of IMS network. IMS was originally a network that provided multimedia services for mobile users. After the R7 version, it was expanded to support WLAN and fixed broadband access, realizing the independence of access. Compared with the mobile aspect, the IMS-based fixed terminal access standard is not very mature. The current IMS network only solves the nomadic control of the service layer, and there is no good solution for the nomadic control of the access layer. [0003] In the IMS network technology, after accessing the roaming network, the user must return to the...

Problems solved by technology

Since the core network cannot determine the user's exact access point through the IP address, and the SBC can only carry its own home network identifier, it cannot carry the user's PANI according to the user's IP address.

In addition, even if the fixed terminal is configured with the SBC domain name of the visited location, it can realize the nearby access, but the area corresponding to the SBC domain name configured by the fixed terminal is relatively large. Generally, the province is used as the unit, which cannot accurately reflect the roaming area of ​​the user.

This makes it difficult for the IMS network to perform accurate nomadic control on fixed terminals and to implement differentiated billing, thus affecting normal business operations.
