Method for concurrent monitoring of multiple communications
First Claim
1. In a digital communication system that includes a plurality of digital communication units, at least one dispatch position, and a base station, a method for a communication unit of the plurality of digital communication units to concurrently and audibly monitor voice information from multiple communications from at least one other communication unit of the plurality of digital communication units and the at least one dispatch position, the method comprising the steps of:
- a) transmitting, by the communication unit, a concurrent monitoring request to the base station;
b) responsive to the concurrent monitoring request, providing, by the base station, multiple communications from the at least one dispatch position and the at least one other communication unit to the communication unit, each of said multiple communications containing voice information; and
c) by the communication unit, simultaneously rendering the multiple communications containing voice information audible to an operator of the communication unit such that said operator of the communication unit can concurrently and audibly monitor voice information from the multiple communications.

Abstract
A communication unit (103) transmits a concurrent monitoring request to a base station (102). Responsive to the concurrent monitoring request, the base station provides multiple communications from at least one dispatch position (101) and at least one other communication unit (104) to the communication unit. Upon reception of the multiple communications, the communication unit simultaneously renders the multiple communications audible, allowing an operator of the communication unit to concurrently monitor the multiple communications.

7. In a digital communication system that includes a plurality of digital communication units, at least one dispatch position, and a base station, a method for a communication unit of the plurality of digital communication units to concurrently and audibly monitor voice information from multiple communications from at least one other communication unit of the plurality of digital communication units and the at least one dispatch position, the method comprising the steps of:
-
a) transmitting, by the at least one dispatch position, a concurrent monitoring command to the base station, wherein the concurrent monitoring command specifies a communication unit of the plurality of communication units as a concurrently monitoring communication unit; b) responsive to the concurrent monitoring command, providing, by the base station, the multiple communications from the at least one dispatch position and the at least one other communication unit to the communication unit, each of said multiple communications containing voice information; and c) by the communication unit, simultaneously rendering the multiple communications containing voice information audible to an operator Of the communication unit, such that said operator of the communication unit can concurrently and audibly monitor voice information from the multiple communications. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method for a digital communication unit to simultaneously receive voice information from multiple communications, the method comprising the steps of:
-
at the digital communication unit; a) receiving an interleaved communication that includes multiple communications, each of said multiple communications containing voice information, wherein each communication of the multiple communications comprises packet-switched, variable-rate, compressed digital audio; b) simultaneously decompressing each communication of said multiple communications to produce decompressed communications; c) summing the decompressed communications to produce a summed communication; and d) rendering audible the summed communication to an operator of the communication unit so that said operator can concurrently and audibly monitor voice information from the multiple communications.

14. A method for a base station to simultaneously provide multiple communications to a digital communication unit, the method comprising the steps of:
-
at the base station; a) receiving, from the digital communication unit, a concurrent monitoring request, wherein the concurrent monitoring request includes identification of at least one dispatch position and at least one other digital communication unit; b) receiving full-rate communications containing voice information from the at least one dispatch position and receiving full-rate communications containing voice information from the at least one other digital communication unit; c) responsive to the concurrent monitoring request, truncating at least a portion of the full-rate communications containing voice information from the at least one dispatch position and the full-rate communications containing voice information from the at least one Other digital communication Unit to produce reduced-rate communications; and d) responsive to the concurrent monitoring request, providing the reduced-rate communications as the multiple communications to the digital communication unit, the multiple communications containing voice information from the at least one dispatch position and voice information from the at least one other digital communication unit. - View Dependent Claims (15)

16. A method for the base station to simultaneously provide multiple communications to a digital communication unit, the method comprising the steps of:
-
at the base station; a) receiving, from at least one dispatch position, a concurrent monitoring command, wherein the concurrent monitoring command includes identification of at least one other digital communication unit; b) receiving full-rate communications containing voice information from the at least one dispatch position and receiving full-rate communications containing voice information from the at least one other digital communication unit; c) responsive to the concurrent monitoring command, truncating at least a portion of the full-rate communications containing voice information from the at least one dispatch position and the full-rate communications containing voice information from the at least one other digital communication unit to produce reduced-rate communications; and d) responsive to the concurrent monitoring command, providing the reduced-rate communications as the multiple communications to the digital communication unit, the multiple communications containing voice information from the at least one dispatch position and voice information from the at least one other digital communication unit. - View Dependent Claims (17)

18. A method for a base station to provide multiple communications to a digital communication unit, the method comprising the steps of:
-
at the base station; a) receiving, from the digital communication unit, a concurrent monitoring request; b) transmitting, responsive to the concurrent monitoring request, a reduced-rate request to at least one other digital communication unit and at least one dispatch position, wherein the reduced-rate request specifies a reduced bit-rate for communications originated by the at least one other digital communication unit and the at least one dispatch position; c) receiving reduced-rate communications containing voice information from the at least one other digital communication unit and receiving reduced-rate communications containing voice information from the at least one dispatch position; and d) providing the reduced-rate communications as the multiple communications to the digital communication unit, the multiple communications containing voice information from the at least one other digital communication Unit and voice information from the at least one dispatch position. - View Dependent Claims (19, 20, 21, 22)
