Embodiment Construction

[0032] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0033] With reference to Fig. 1, according to the automatic selection method of the home subscriber server of IP multimedia subsystem of the present invention comprises the following steps:

[0034] Step S102, respectively setting interfaces between the user location function device and multiple home user servers.

[0035] Data replication is performed synchronously or asynchronously among multiple home user servers.

[0036] In step S104, the user location function device queries the states of multiple home user servers through the interface according to a predetermined timing, and updates the records.

[0037] The user location function device initiates status query requests to multiple home subscriber servers, and determines the status of each home subscriber server according to the responses or no responses of the multiple home subscriber servers.

Abstract

This invention discloses a method for selecting homing user servers of IP multimedia subsystem automatically, which sets interfaces between a user locating function device and multiple homing user servers, and the user locating functional device enquires the state of the multiple homing user servers periodically and updates records, a call session control functional device enquires information of the servers to the user locating function device, which selects one available server and feeds back the information to the call session control function device based on recorded state of the multiple servers, when a HSS is faulty, SLR can identify it timely and switches the access path of CSCF to a disaster recovery backup corresponding to the faulty HSS automatically by SLF side so as to guarantee correctness of business.

Description

technical field [0001] The invention relates to an IP multimedia subsystem, in particular to a method for automatically selecting a home user server of the IP multimedia subsystem and an IP multimedia subsystem for automatically selecting a home user server. Background technique [0002] In the IP Multimedia Subsystem (IMS) specified by 3GPP R5, HSS (Home Subscriber Server, Home Subscriber Server) is a central database for storing user-related information, which is equivalent to HLR (Home Location Register, home location register) of traditional mobile networks. register). In addition to storing the user's subscription information and location information, the HSS also stores customized data related to the user and used to process multimedia sessions, including: local information, confidential information (certificate and authorization information), registration information, service trigger information, User personal information and S-CSCF (Serving Call Session Control Func...
