Abstract

The development of broadband access technologies makes it possible for PMR network to improve both the performance and capacities. However, a fully deployed PMR network requires a long time and huge investments. The integration of dedicated and commercial networks could be a promising solution to this problem. This article contributes to the evolution of PMR networks by proposing a novel system for the integration of PMR and commercial networks. This system enables Internet users to communicate with PMR users by various access networks ranging from Ethernet to wireless networks like LTE and WiFi. Therefore, any authorized user can exchange multimedia information with PMR user with any device having access to Internet. Based on the extended SIP, a uniform interface of multimedia services is proposed for multiple access technologies. The functional and technical performance of the system is checked out on integrated test bed.
