System and method for pausing an ongoing transmission in a communication system
First Claim
1. A method for pausing a transmitting mobile or portable radio in a communication system comprising:
- transmitting, by the transmitting mobile or portable radio, a communication on a forward channel of a communication system while listening to a reverse channel wherein the forward channel comprises a first timeslot of a TDMA communication, and the reverse channel comprises a portion of a second timeslot of the TDMA communication;
receiving, at the transmitting mobile or portable radio, from a second mobile or portable radio operating in a direct mode, or from a base station when the second mobile or portable radio is not operating in the direct mode, on the reverse channel, a request to pause signal;
ceasing transmission of the communication on the forward channel by the mobile or portable radio for a period of time in response to the request to pause signal; and
automatically resuming transmission of the communication on the forward channel by the mobile or portable radio after the period of time has elapsed;
wherein the reverse channel is used for the second mobile or portable radio to send reverse channel signaling on an inbound channel to another radio via a base station and is also used to allow the second mobile or portable radio to directly send reverse channel signaling to another radio when operating in a direct mode; and
wherein the period of time is based on whether or not the second radio is operating in the direct mode.

Abstract
A system and method for pausing communications from a transmitting radio for a certain period of time in order to allow transmission of other messages. When a first radio determines that a message needs to be transmitted either to a second radio or the transmitting radio, the first radio determines whether there are any available forward channels to transmit the call. If no forward channel is available, the first radio determines a period of time required to transmit the message and sends, on a reverse channel, a “request to pause” signal to the transmitting radio identifying that period of time. Upon receiving the “request to pause” signal, the transmitting radio ceases transmission on the forward channel for the specified period of time, during which time the first radio transmits the message.

7. A method for pausing a transmitting a mobile or portable radio in a communication system comprising:
-
a first mobile or portable radio performing; determining that a message is to be sent to a second mobile or portable radio; identifying that a forward channel used for transmitting communications in the communication system is busy; determining a period of time required to transmit the message; transmitting a request to pause signal on a reverse channel, the request to pause signal including information indicating the period of time required to transmit the message;
transmitting the message on the reverse channel;wherein the forward channel comprises a first timeslot of a TDMA communication, and the reverse channel comprises a portion of a second timeslot of the TDMA communication; wherein the reverse channel is used for the first mobile or portable radio to send reverse channel signaling on an inbound channel to second radio via a base station and is also used for the first mobile or portable radio to directly send reverse channel signaling to the second radio when operating in a direct mode; and
wherein the period of time is based on whether or not that the second radio is operating in the direct mode. - View Dependent Claims (8, 9, 10, 11, 12)

13. A communication system comprising:
-
a plurality of mobile or portable radios, the plurality of radios including; a transmitting mobile or portable radio that transmits a communication on a forward channel of the communication system while listening to a reverse channel, wherein the forward channel comprises a first timeslot of a TDMA communication, and the reverse channel comprises a portion of a second timeslot of the TDMA communication; and a first mobile or portable radio configured to determine that a message is to be sent to the transmitting mobile or portable radio;
identify that the forward channel being used by the transmitting mobile or portable radio is busy;
determine a period of time required to transmit the message; and
transmit a request to pause signal on the reverse channel, the request to pause signal including information indicating the period of time required to transmit the message;wherein the first mobile or portable radio transmits the request on the reverse channel to a base station and also transmits the request on the reverse channel directly to the transmitting mobile or portable radio when operating in a direct mode; and wherein the period of time is based on whether or not that the second radio is operating in the direct mode; wherein upon receiving the request to pause signal on the reverse channel from the first mobile or portable radio, the transmitting mobile or portable radio ceases transmission of the communication on the forward channel for the period of time indicated in the request to pause signal. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
