| Abstract: | The long-term evolution （LTE） system is regarded as the most possible next-generation railway mobile communication platform. Issues on service capability and inter-connection between LTE and GSM-R in case of co-existing are studied. These issues mainly include implementation means of the existing GSM-R services in a LTE system, coupling means of the two systems, cell-reselection between the two systems, carrier services, and so on. The convergence solution between core-networks and terminals are discussed. It is demonstrated that it is feasible for the co-existing and inter-connection between LTE and GSM-R systems. |
