Abstract

Apparatus, and an associated method, for a fixed wireless access communication system (10), by which to initiate a call to an emergency dispatch center (338), or other priority call to a priority location. When communication resources are initially unavailable to permit establishment of the call, normal call set-up procedures are emulated (408) at a subscriber station (304) from which the call is to be originated. Communication resources are reallocated in the communication system (10) to permit the establishment of the call and the call is thereafter established.
