Method for group call communication
First Claim
1. A method for improving repeater-enabled group call coverage within a wireless communication network comprising at least an originator wireless communication device, a repeater device, and a plurality of target wireless communication devices, the method comprising:
- eavesdropping, by at least a particular one of the plurality of target wireless communication devices, on a wireless uplink channel between the at least one originator wireless communication device of a repeater-enabled group call and the repeater device and receiving at least one preamble slot, at least one synchronization slot, and at least one repeater request directly from the originator wireless communication device via the eavesdropped wireless uplink channel, wherein the particular target wireless communication device is within a wireless transmission range of the originator wireless communication device, thereby increasing a wireless coverage area of the repeater-enabled group call to a union of a coverage area of the repeater device and a coverage area of the originator wireless communication device;
determining, by the particular target wireless communication device, whether a direct received signal strength indication (RSSI) of signals received directly from the originator wireless communication device via the eavesdropped wireless uplink channel is greater than a threshold;
operating the particular target wireless communication device to receive the repeater-enabled group call directly from the originator wireless communication device via the eavesdropped wireless uplink channel, instead of on a repeater downlink channel of the repeater device where the repeater-enabled group call will also be made available by the repeater device, when the determining is that the direct RSSI of the signals received directly from the originator wireless communication device is greater than the threshold; and
operating the particular target wireless communication device to receive the repeater-enabled group call from the originator wireless communication device via the repeater device on the repeater downlink channel of the repeater device, instead of directly from the originator wireless communication device via the eavesdropped wireless uplink channel, when the determining is that the direct RSSI signals received directly from the originator wireless communication device is not greater than the threshold.

Abstract
A method for communicating a group call within a communication network comprising at least one repeater and a plurality of communication devices includes: receiving at least one preamble slot and at least one synchronization slot from an originator communication device by the repeater and a communication device; operating the communication device to receive one or more calls directly from the originator device via eavesdropping on the repeater uplink channel when a received signal strength indication (RSSI) of the direct preamble and synchronization slots is greater than a threshold; and operating the communication device to receive one or more calls from the originator device via the repeater on a repeater downlink channel of the repeater when the direct RSSI is not greater than the threshold.

12. A method for improving repeater-enabled group call coverage within a wireless communication network comprising at least an originator wireless communication device, a repeater device, and a plurality of target wireless communication devices, the method comprising:
-
eavesdropping, by at least a particular one of the plurality of target wireless communication devices, on a wireless uplink channel between the at least one originator wireless communication device and the repeater device of a repeater-enabled group call and receiving at least one preamble slot, at least one synchronization slot, and at least one repeater request directly from the originator wireless communication device via the eavesdropped wireless uplink channel, wherein the particular target wireless communication device and the repeater device are within a wireless transmission range of the originator wireless communication device, thereby increasing a wireless coverage area of the repeater-enabled group call to a union of a coverage area of the repeater device and a coverage area of the originator wireless communication device; receiving, by the particular target wireless communication device, retransmitted ones of the at least one preamble slot and the at least one synchronization slot by from the repeater device on a downlink channel of the repeater device; comparing, by the particular target wireless communication device, an uplink direct received signal strength indication (RSSI) of the wireless uplink channel from the originator wireless communication device to the repeater device, to an indirect downlink RSSI of the downlink channel from the repeater device; operating the particular target wireless communication device to receive the repeater-enabled group call directly from the originator wireless communication device via the eavesdropped wireless uplink channel, instead of on a repeater downlink channel of the repeater device where the repeater-enabled group call will also be made available by the repeater device, when the uplink RSSI is greater than the downlink RSSI; and operating the particular communication device to receive the repeater-enabled group call from the originator wireless communication device via the repeater on the downlink channel of the repeater device, instead of directly from the originator wireless communication device via the eavesdropped wireless uplink channel, when the uplink RSSI is not greater than the downlink RSSI. - View Dependent Claims (13, 14, 15, 16)
