Abstract

The present disclosure provides a system and a method for providing mobility management and out-of-coverage indication in a conventional Land Mobile Radio (LMR) system. A radio provides its location and user group data to the disclosed system through its traffic channel when the channel is idle. Knowledge of the radio'"'"'s current location and user group data is used to provide dynamic call routing and data management within the disclosed system. The disclosed system and method may provide operability similar to that of a trunking system by providing mobility management and out-of-coverage indication while providing low-cost benefits through operation of a conventional system.

Claims

1. A method for providing mobility management and out-of-coverage indication in a conventional land mobile radio system, the method comprising:

transmitting data packets across a traffic channel from a first land mobile radio site in the system to a radio, the receipt of the data packets indicating that the radio is within coverage of the system;

sending current radio data across the traffic channel from the radio to the first land mobile radio site when the traffic channel is idle;

updating the system with the current radio data; and

indicating that the radio is out-of-coverage if the radio does not detect activity on the traffic channel for an allotted amount of time.
