Abstract

This publication describes a method whereby a Fixed End Operator is able to initiate the dynamic regrouping of a radio to a trunking radio system while the radio in question is operating on an advanced conventional (MDC) system. Given a radio that has both tnmking and advanced conventional capabilities, if you wish to regroup the radio to a trunking talkgroup, but the radio is currently using its advanced conventional capability, the futed end would not be able to communicate the regroup request to the radio until such time that the Radio User switches his radio over to a trunking chan- nel. In other words the problem resolved by this inven- tion is how to effect a trunking regrouping when the radio is not currently communicating on a trunking sys- tem but on an MDC one.

EXECUTION OF A TRUNKING RADIO REGROUP WHEN THE RADIO IS ON AN ADVANCED CONVENTIONAL SYSTEM

by Melvyn M. David

  This publication describes a method whereby a Fixed End Operator is able to initiate the dynamic regrouping of a radio to a trunking radio system while the radio in question is operating on an advanced conventional (MDC) system. Given a radio that has both tnmking and advanced conventional capabilities, if you wish to regroup the radio to a trunking talkgroup, but the radio is currently using its advanced conventional capability, the futed end would not be able to communicate the regroup request to the radio until such time that the Radio User switches his radio over to a trunking chan- nel. In other words the problem resolved by this inven- tion is how to effect a trunking regrouping when the radio is not currently communicating on a trunking sys- tem but on an MDC one.

  The use of this invention can be found for radios that are capable of both trunking and advanced conven- tional operations. In such mixed systems this invention broadens the inter-operability of radios with this capac- ity to operate in both environments by allowing a radio using its advanced conventional capability to be switched to a trunking system.

  The following describes, in a chronological sequence, the intended operation of this invention. The algorithm used is shown in the accompanying flow chart.

  Initially the Fixed End Operator assigns radios that have both trunking and advanced conventional opera- tions the same radio alias in the trunking fixed end database. Various radios are also assigned to trunking talkgroups.

  The Fixed End Operator next decides to initiate a regrouping to a trunking talkgroup for one or more radios. Regroup commands are sent out to the radios in question on the tmnking system. Acknowledgements are returned by the radios to the futed end upon successful

receipt of the regroup command.

  After sufficient time has been given to waiting for radio acknowledgements and for possible commu- nications re-tries, the fixed end determines that the radio(s) in question are probably either turned off, or operating on the advanced conventional system. At this point an advanced conventional "switch to trunking system" command is sent out to the radio still operating on the trunking system. This command will cause the radio...
