Reduction of Channel Idle Time in a Trunked Mobile Radio Network

Abstract

Public Access Mobile Radio (PAMR) networks offer a wide choice of services including selective or group voice and data calls, PABX interconnect and callback for unattended radio units. A high grade-of-service is achieved through trunking, coupled with the ability to queue. The user’s perception of network performance is usually obtained through highly visible parameters such as call set-up delay and quality of speech. Inefficiencies in the management of the individual network resources tend to remain hidden primarily because they impact on network capacity rather than performance. Such a network will expand in accordance with growth in its user base. To release more capacity we must reduce the time that valuable resources remain idle once allocated. In this paper we will address the idle time of the radio traffic channel resource.
