Abstract

Mobile communication systems and methods consistent with the present invention include a central station, a mobile unit and a plurality of radio base stations The mobile unit communicates with the central station through one of the radio base stations. The central station receives from the mobile unit registration information identifying the radio base station the mobile unit is currently communicating with. This registration information is then stored in a registration database located at the central station. Files are then transferred from the central station to the mobile unit using the radio base station identified by the registration information stored in the registration database.

Claims

1. A method for transferring data in a communication system, the communication system comprising a central station, a plurality of mobile units, and a plurality of radio base stations, wherein the central station communicates with each of the plurality of mobile units, the method comprising:

receiving from each mobile unit registration information identifying a radio base station currently in communication with the mobile unit;

storing the registration information in a registration database located at the central station, such that the registration database stores information identifying the particular radio base station currently communicating with each of the plurality of mobile units;

receiving a request to transfer data to a selected group of the plurality of mobile units;

transferring data from the central station to the selected group of mobile units using the radio base stations identified by the registration information stored in the registration database for each mobile unit in the selected group, and wherein the transferring step further includes;

transmitting to a particular mobile unit a call request identifying data that the central station requests to transfer;

receiving an acknowledgment signal from the particular mobile unit indicating whether the particular mobile unit can receive the requested data; and

transferring the requested data to the mobile particular unit when the acknowledgment signal indicates that the particular mobile unit can receive the requested data.

2. A mobile communication system comprising:

a plurality of mobile units for receiving and transmitting broadcast signals, each mobile unit having at least one server operatively coupled to a plurality of telephones;

a plurality of radio base stations for transmitting and receiving broadcast signals to and from the plurality of mobile units;

a central station for communicating with each mobile unit through one of the radio base stations, the central station further including;

a registration database including registration information identifying the radio base station currently in communication with each mobile unit; and

a switch control processor for transferring data to a selected group of the plurality of mobile units using the radio base stations identified by the registration information stored in the registration database for each mobile unit in the selected group, wherein the switch control processor further includes;

means for transmitting to a particular mobile unit a call request identifying data that the central station requests to transfer;

means for receiving from the particular mobile unit an acknowledgment signal indicating whether the particular mobile unit can receive the requested data; and

means for transferring the requested data to the particular mobile unit when the acknowledgment signal indicates that the particular mobile unit can receive the requested data.
