Idle Channel Broadcast in Mobile Radio Systems

Abstract

This is a method for distributing low priority information in a two-way radio system by using the system's idle time. The system is preferably a digital system, e.g. TETRA.

Introduction

This paper describes a method for using idle time more efficiently, in radio systems that use an infrastructure. This time is wasted in some of these systems. Examples of these are systems are e.g. MPT1327 and TETRA.

Problem To Be Solved

In current mobile radio systems network information and system broadcasts are transmitted occasionally by the infrastructure as required. This is e.g. as described in GSM and TETRA.

Proposed Solution to the Problem

Unlike the standard occasional TETRA or GSM broadcast ability, this system uses it's idle time to transmit low priority information to the mobile radios. Due to the fact that this transmission can be interrupted at any time, e.g. by a call, an abort and resume mechanism is required.

This low priority information can then be stored as data or audio inside the mobile radio unit. Sufficient RAM (random access memory) is required in the mobile radio units to do this. The operator of the mobile radio can evaluate and/or maintain the data when it is convenient to do so. It must also be possible for the operator to select only desired (subscribed) information, i.e. store only specific types of news, which have been selected previously.

The transmitted i...
