Abstract

A trunked communication system wherein less than all of the communication units may transmit an identifying data word thereby registering their location to a system controller every time they enter a different coverage area, while the remainder of the communication units do not. The identity of the communication units which operate in each mode is known to the system resource controller in advance. Pre-registration allows the system controller to know the locale of target units in advance when communications to those units is requested. The locale of units that do no pre-register their location are identified through system wide paging. Coordinating the identification of locales of units in both modes permits greater optimization of spectral resources.
