Method and apparatus for controlling transmissions in a two-way selective call communication system
First Claim
1. A method in a two-way selective call communication system for controlling transmissions in a dominant cell of a plurality of cells utilizing a common radio frequency for sending messages, the dominant cell carrying significantly greater traffic than any other cell of the plurality of cells, the method comprising the steps of:
- grouping, into a first time period, the transmissions of non-dominant cell messages which interfere with the transmissions of dominant cell messages;
determining a subset of the dominant cell messages that require a higher signal-to-interference ratio than available in the dominant cell during the first time period; and
transmitting the subset during a second time period different from the first time period.

Abstract
A two-way selective call communication system (FIG. 1) controls transmissions in a dominant cell (504) of a plurality of cells (502, 504) utilizing a common radio frequency for sending messages (408). The dominant cell carries significantly greater traffic than any other cell of the plurality of cells. A controller (112) groups (808, 906), into a first time period (708), the transmissions of non-dominant cell messages which interfere with the transmissions of dominant cell messages. The controller then determines a subset of the dominant cell messages that require a higher signal-to-interference ratio than available in the dominant cell during the first time period. The controller then transmits (908) the subset during a second time period (710) different from the first time period.

11. A controller in a two-way selective call communication system for controlling transmissions in a dominant cell of a plurality of cells utilizing a common radio frequency for sending messages, the dominant cell carrying significantly greater traffic than any other cell of the plurality of cells, the controller comprising:
-
a telephone interface for receiving the messages from a telephone network; a processing system coupled to the telephone interface for grouping the messages such that the transmissions of non-dominant cell messages which interfere with the transmissions of dominant cell messages are grouped into a first time period; a receiver interface coupled to the processing system for cooperating with the processing system to determine a subset of the dominant cell messages that require a higher signal-to-interference ratio than available in the dominant cell during the first time period; and a transmitter interface coupled to the processing system for transmitting the subset during a second time period different from the first time period. - View Dependent Claims (12, 13, 14, 15)
