Abstract
A telephone communication system having a locator and a scheduling facility includes: a PBX connected to telephones for facilitating communication between users; a scheduling unit for storing user schedule information for the users; and a locator system for providing location information. The locator system includes portable units associated with respective users which transmits an identification signal for identifying the user. The portable units include portable computing devices for interactively processing scheduling information with the scheduling unit. Transceivers receive the unit information from the portable units for forwarding the unit information to the PBX to determine location information of the users. The PBX activates telephone functions for use in conjunction with the location information for communicating with a called user, and the PBX accesses the user schedule information of a first user, for retrieving a specific location associated with the first user for generating a schedule notification message for communication to the first user at the specific location thereof.
