Problems solved by technology

[0011] In the case of local deployment of the IMS network, if the user roams to the IMS network of the visited location, and the intermediate network between the IMS network of the home location and the IMS network of the visited location is not deployed with an IMS network, it may not be possible to send the message of the UE ( For example, registration messages, session invitation messages) are routed to the home network, resulting in failure of IMS services; similarly, messages sent by the home network to the UE (for example, session invitation messages) may not be routed to the visited IMS network

Embodiment Construction

[0074] The core idea of ​​the present invention is to set up a visitor subscriber server (Visitor Subscriber Server, referred to as VSS) in the IMS network. The registration request is sent to the VSS in the local IMS network through the S-CSCF of the local IMS network for local registration. After the VSS receives the registration request, if the corresponding user data is not stored locally, it will send the registration request to the home location register of the user's home network. (Home Location Register, referred to as HLR) or Home Subscriber Server (Home Subscriber Server, referred to as HSS) sends a location update request to obtain corresponding user data, and after saving the user data, the subsequent registration process is completed.

[0075] The present invention will be described in detail below with reference to the drawings and embodiments.

Abstract

The invention relates to a user registration method of an IP multimedia subsystem (IMS) network. The method comprises the following steps of: after UE (User Equipment) sends a registering request to P-CSCF (Proxy Call Session Control Function) of the local IMS network under a roaming state, transmitting the registering request to the S-CSCF (Serving Call Session Control Function) of the local IMS network by using the P-CSCF through the I-CSCF (Interrogating Call Session Control Function) of the local IMS network; after receiving the registering request, if a VSS (Voice Signaling System) has no the user data of the UE, sending a location updating request to a HLR (Home Location Register) or HSS (Home Subscriber Server) of a home network of the UE; after receiving the location updating request, returning the user data of the UE to the VSS by using the HLR or the HSS; saving the user data by using the VSS, identifying that the UE has been registered, returning a registering response message to the S-CSCF, and accomplishing the subsequent registering processes by using the S-CSCF.

Description

technical field [0001] The invention relates to the communication field, in particular to a user registration method and a service realization system of an IP (Internet Protocol, Internet Protocol) multimedia subsystem network. Background technique [0002] In order to maintain the competitiveness of the 3rd Generation Partnership Project (abbreviated as 3GPP) in the field of mobile communications, 3GPP is currently working on the research on packet switched core network (Packet Switched Core, abbreviated as PS Core) and global mobile communications The evolution of the Universal Mobile Telecommunication System Radio Access Network (UTRAN) aims to enable the evolved PS Core (EPC) to provide higher transmission rates, shorter transmission delays, and support E -UTRAN (Evolved UTRAN, evolved UTRAN), GERAN (GSM EDGE radio access network, Global System for Mobile Communications Enhanced Data Rate Global System for Mobile Communications Evolution Technology Wireless Access Networ...
