Method for providing caller interrupt in a time division multiplexed wireless communication system
First Claim
1. In a TDM wireless communication system that includes a plurality of communication units arranged into at least one communication group, a plurality of wireless communication resources, and a central controller that allocates the plurality of wireless communication resources among the plurality of communication units, a method for providing caller interrupt, the method comprising the steps of:
- a) transmitting, by a first communication unit of the at least one communication group, a request for a group call;
b) upon receiving the request, allocating, by the central controller, a first inbound wireless communication resource, a second inbound wireless communication resource, and an outbound wireless communication resource;
c) transmitting, by the first communication unit via the first inbound communication resource, primary voice signals;
d) receiving, by the central controller via the first inbound wireless communication resource, the primary voice signals;
e) retransmitting, by the central controller, the primary voice signals via the outbound wireless communication resource;
f) transmitting, by a second communication unit of the at least one communication group, interrupt voice signals on the second inbound wireless communication resource while the first communication unit is currently transmitting;
g) receiving, by the central controller via the second inbound wireless communication resource, the interrupt voice signals;
h) summing, by the central controller, the interrupt voice signals and the primary voice signals to produce summed voice signals; and
i) transmitting, by the central controller, the summed voice signals on the outbound wireless communication resource, thereby providing caller interrupt.

Abstract
A first communication unit (101) transmits, to a central controller (105), a request for a group call. The central controller allocates a first inbound (11), a second inbound (12), and an outbound (O1) wireless communication resource for use in the group call. At the central controller, primary voice signals from the first communication unit, received via the first inbound wireless communication resource, are summed (109) with interrupt voice signals from a second communication unit (102), received via the second inbound wireless communication resource, to produce summed voice signals. The summed voice signals and a busy signal (108) are transmitted via the outbound wireless communication resource, thereby allowing the second communication unit to interrupt the group call. Additionally, the central controller can allocate a third inbound communication resource (13) for use with priority interrupt voice signals which can also be summed with the primary and interrupt voice signals.
