Abstract

The invention provides an automatic routing networking method and device for a distributed IMS (IP Multimedia Subsystem), and belongs to the technical field of mobile communication. The method comprises the following steps of: pre-configuring a unique network element ID (Identity) for each integrated IMS (IP Multimedia Subsystem) bearing station in a communication system, and establishing a forced mapping relationship between a user number and the network element ID of the bearing station and a forced mapping relationship between the network element ID of the bearing station and an IMS service intercommunication network address; when the calling bearing station receives the initial calling request, the called user number is analyzed to obtain the network element ID of the called bearing station; judging whether the network element ID of the called bearing station is the same as the network element ID of the called bearing station; if not, an IMS service intercommunication network address corresponding to the called bearing station is searched according to the mapping relation, and the call request is routed to the address; and if yes, direct routing is carried out in the station. According to the method and the device, the network topology information is embedded in the user identifier, so that automatic routing of the call is realized, a complex global routing table does not need to be maintained, and the expansibility and the flexibility of the system are improved.
