Abstract

PURPOSE: To control incoming to a proper mobile station closest to a terminating user in both of the case that a mobile station is shared among plural users and the case that an arbitrary user temporarily carries and uses it. CONSTITUTION: When user IDs of users who share mobile stations are inputted from mobile stations 12-1 to 12-n, user ID of users are stored in a sharing user management table of a main device 10-1. When states of mobile stations (being carried and used or being shared) and user IDs are inputted, states of mobile stations are stored in a mobile station state management table of the main device, and user IDs of carrying persons are stored in a carrying user management table in the case of mobile stations which are carried and used. When determining the incoming destination by a switching control means, the main device 10-1 retrieves the user ID of the terminating user from an extension number management table and retrieves the mobile station, which the terminating user is registered for, from the sharing user management table and determines this mobile station as the incoming destination mobile station.

[0021]

As is apparent from the above description, the present invention has the following effects. (1) Since an extension number can be given to each user and the mobile station to be used can be changed at any time, it is not necessary to change the extension number associated with the movement of seats even in a cordless telephone system composed of fewer mobile stations than the number of users. There is an effect. (2) Even when an arbitrary user temporarily carries a mobile station shared by a plurality of users and leaves his / her desk, it becomes possible to receive only an incoming call addressed to the user carrying the mobile station, which is wasteful. It has the effect of limiting incoming calls. (3) In (2) above, when an arbitrary user temporarily carries a mobile station and leaves his / her desk, even the other users who shared the carried mobile station are most likely to be called users. It is possible to make an incoming call to a nearby mobile station.
