Abstract

A real-time phonebook update system in a mobile communication network and a method thereof are provided to match the phonebook data of a mobile terminal with the phonebook data of a phonebook data server in real time by implementing real-time phonebook synchronization between the mobile terminal and the phonebook data server. A real-time phonebook update system in a mobile communication network consists of the first mobile terminal(10), a CSCF(Call Session Control Function)(110), a presence server(120), and the second mobile terminal(20). The first mobile terminal adds the contact information of the second mobile terminal to its own phonebook, creates phonebook data, and registers the modified phonebook data in the presence server. If a phonebook data modification event is generated from the first mobile terminal as the contact information of the second mobile terminal is added, the CSCF forms a real-time session with the presence server and the second mobile terminal and controls the session so that data transmission can be executed. The presence server receives the modified phonebook data from the first mobile terminal, stores the received data through real-time synchronization, and reports the modification details of the modified phonebook data to the second mobile terminal through the CSCF. The second mobile terminal receives the modification details of the modified phonebook data from the presence server, adds the phonebook of the first mobile terminal, stores it through real-time synchronization, and transmits its own phonebook modification details to the presence server through the CSCF.

Therefore, the definition should be made based on the contents throughout the specification.

Prior to describing the present invention, the IMS network and service functions to which the present invention is applied will be described.

IMS (IP Multimedia Subsystem) is a key technology for providing new services in the next generation communication environment based on ALL IP, and enables multimedia communication such as video and large data even in a voice-oriented network structure.

At this time, unlike the existing circuit-oriented network system, IMS provides all services based on IP.

The IMS is basically defined by three logical core components: a transport (gateway) layer, a control (session control) layer, and a service (application) layer.

First, the transport (gateway) is an IP network built inside a carrier network, which connects the IMS network with other IMS networks, public switched telephone networks (PSTNs), and other existing networks and carrier operation support systems. do.

Next, the control (session control) is composed of servers that enable SIP services, call session control function (HSS) and home subscriber server (HSS) to register user terminals and route SIP signaling to the appropriate server. And HLR, a centralized database for managing subscriber information, performing functions such as user registration / change management, authentication, authorization, location, session routing, and billing.

In addition, services (applications) provide SIP-based applications such as games, video, and group chat, and include user service logic.

First, as shown in FIG. 1, the IMS network is an infrastructure system that performs basic functions for SIP-based multimedia session control, and is equipped with a CSCF for performing call processing. Proxy call session controller (P-CSCF) that performs routing and forwarding of packets to the access point to be connected, and relay call session controller (I-) that allows all connections to roaming subscribers currently located within the service area of the network operator. CSCF), and a serving call session controller (S-CSCF) that performs session control of a user terminal.

In addition, the subscriber profile information, authentication and location-related data is stored, and the home subscriber server (Home Subscriber Server) responsible for the collection function of the serving call session controller (S-CSCF) and the actual service logic to provide the service An application server exists and forms a MRF (Multimedia Resource Function) for handling call control and media mixing for multi-party services.

In addition, the IMS network is premised on interworking with the legacy legacy network PSTN, MGCF (Media Gateway Control Function) for signaling conversion for interworking with IMS network and legacy network, and IMS-MGW (Media Gateway) for media conversion. In addition, BGCF is also configured to select the appropriate MGCF in consideration of routing optimization for PSTN incoming signals.

In order to access the IMS network, the terminal must go through an IP-CAN (IP-Connectivity Access Network), and the IP-CAN is an access network for packet data transmission to the terminal.
