4A and 4B are diagrams illustrating the configuration and implementation of the integrated presence DB 120.

In FIG. 4A, the subscriber's identifier table 10 and the information tables 10_1, 10_2, ... of the network terminals for each identifier are shown.

The subscriber's identifier table 10 includes a subscriber's integrated identifier, individual network identifiers, a subscriber service profile, and a subscriber's presence information field, and information tables 10_1 and 10_2 of the network terminal for each party are terminal identifiers, It consists of the name of the terminal, the capability of the terminal (voice, wireless web, short message service, etc.), the profile of the terminal and the terminal presence information fields.

The corresponding terminal information is connected to the information tables 10_1, 10_2, ... of the corresponding network terminal for each identifier for the individual identifier field of the subscriber identifier table 10.

FIG. 4B illustrates an example of such an integrated presence table. It is assumed that individual network terminal information for each integrated identifier table is generated for each wired, wireless, and Internet service.

'Hong Gil-dong' subscribers with the integrated identifier managed by the integrated presence service as '1234' have a phone number (TELEPHONE_ID), a wireless phone number (Mobile_ID), and an instance messenger ID (IM_ID) for each network. It can be seen that the registered terminal is a wired telephone and the communication preference is mainly a mobile terminal based on subscriber profile data.

At this time, the detailed information about the subscriber's wired terminal is described in the linked table 20_1. The wired telephone number is '02 -111-1111 ', the terminal capability is' voice', and the communication preference among the profile of the subscriber. , WHITE_SCREEN (the number you want to dial in) and BLACK_SCREEN LIST (the number you do not want to dial in) are 02-222-2222 and 02-333-3333 respectively, and the routing number for each time zone is between 21:00 and 06:00.
