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

[0070] The core idea of ​​the present invention is to set an enhanced mobile switching center (E-MSC) in the local IMS network. During the registration process of the user, a location update request is sent to the HSS / HLR of the user's home network to obtain the user data of the visiting user, so as to realize the local storage of the user data of the visiting user, and then realize the local registration of the visiting user.

[0071] The present invention will be described in detail below with reference to the drawings and embodiments.

[0072] figure 2 It is the architecture of the service implementation system of the IMS network in the embodiment of the present invention Figure 1 ,include:

[0073] 201: User Equipment (User Equipment, referred to as UE); has IMS capabilities, supports the SIP protocol, and is used to register with the P-CSCF in the IMS network through the access device, and establish a session connection with the remote end;

Abstract

The invention relates to a method for user registration of an IP multimedia subsystem network. After UE sends a registration request to P-CSCF of a local IMS network in a roaming state, the method comprises the following steps that: the P-CSCF forwards the registration request to S-CSCF of the local IMS network through I-CSCF of the local IMS network, and the S-CSCF forwards the registration request to E-MSC of the local IMS network; after receiving the registration request, the E-MSC sends a position update request to HLR or HSS of a UE home network if user data of the UE does not exist in the E-MSC; the HLR or HSS returns the user data of the UE to the E-MSC after receiving the position update request; and the E-MSC stores the user data, identifies the UE as registered UE and returns a registration response message to the S-CSCF; and the S-CSCF completes subsequent registration processes.

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...
