Performance of trunked mobile radio networks based on MPT 1343 standard for voice and data transmission

This paper considers the performance of a trunking system based on the MPT 1343 standard. Particular attention has been paid to the transmission of short data messages over the control channel in the presence of signalling required for the set-up of simple calls for speech and non-prescribed data transmission. In order to determine the performance, a simulation tool has been developed. This tool simulates a single-site trunking system with mobile radio units and connections to PSTN and PABX extension numbers. After a brief introduction to the protocol and standard user facilities, the simulation model and implementation of access scenarios are described. The most relevant simulation results are presented and discussed. Minor differences between MPT 1327 and MPT 1343 are beyond the scope of this paper and are not considered here.
