Method and apparatus for extending coverage in a wireless communication system

摘要

A first radio receives, via a land mobile radio (LMR) radio frequency transceiver, a first transmission of an LMR call from a source transmitting radio transmitted on a first LMR frequency for re-transmission to one or more destination radios. The first radio measures a first measured signal level of the first transmission and receives, via a first short-range RF transceiver from a second radio, a second measured signal level of the first transmission as measured by the second radio. The first radio compares the first measured signal level and the second measured signal level and determines, based on the comparing, how the LMR call should be routed from the source transmitting radio to the one or more destination radios via the first and second radios. The first radio then transmits, via the first short-range RF transceiver, a corresponding instruction indicating a result of the determining to the second radio.

1. A method comprising:
receiving, via a first land mobile radio (LMR) radio frequency (RF) transceiver at a first short-range paired radio, a first transmission of an LMR call from a source transmitting radio on a first LMR frequency for re-transmission to one or more destination radios; measuring, at the first short-range paired radio, a first measured signal level of the first transmission transmitted by the source transmitting radio; receiving, at the first short-range paired radio via a first short-range RF transceiver and from a second short-range paired radio, a second measured signal level of the first transmission transmitted by the source transmitting radio as measured by the second short-range paired radio; comparing, by the first short-range paired radio, the first measured signal level and the second measured signal level; determining, by the first short-range paired radio based on the comparing, how the LMR call should be routed from the source transmitting radio to the one or more destination radios via the first and second short-range paired radios; and transmitting, via the first short-range RF transceiver at the first short-range paired radio, a corresponding instruction indicating a result of the determining to the second short-range paired radio.
