Abstract
The control and management of new urban guided-transport systems such as tramways and subways are based on several IT services with heterogeneous data communication requirements. These applications are known as CBTC (Communication Based Train Control systems) and CCTV (Closed Circuit TeleVision). In order to support existing as well as emerging applications over a unique communication infrastructure, it is mandatory to be able to ensure efficient QoS management that meets the requirements of CBTC and CCTV services especially the critical ones. This paper presents an evaluation of QoS provisioning in LTE (Long Term Evolution) based communication system for urban guided-transport. The evaluation is made through simulations with the well known event driven simulator OPNET. We propose a mapping of the typical applications CBTC and CCTV to standardized 3GPP QCIs (QoS Class Identifiers) that serve as a basis for the LTE class-based QoS. After discussion of the obtained results, we provide recommendations to enhance the communication performances experienced by these applications.
