Deploying mobile relays in public transportation is a simple yet effective way to avoid the electromagnetic insulation within vehicles and to increase the Quality of Service (QoS) perceived by passengers, which is sometimes low. Mobile relaying can be done by using an LTE/EPC 100%-compatible architecture. However, this solution induces extra-overhead. In this paper we evaluate the QoS of an LTE mobile relay architecture for public railway transport systems for two representative services: client-server requests and voice communications. We compare the performance of a direct transmission against a mobile relay architecture for different types of requests and different load conditions. This work, therefore, evaluates the mobile relay performance in terms of load time, throughput, packet loss ratio and end-to-end latency. Our findings show that a mobile relay architecture highly improves the QoS performance for train passengers. Furthermore, the gain is greater as the load increases.

“…Two key aspects of relay operation mode are: the method of communication (duplex or half-duplex) and the backhaul and access links operation bands (in-band or out-band). For inband relays, both links work in the same frequency band, so they are multiplexed in time domain on subframe basis [5].…”

“…Finally, in order to ensure compatibility with terminals of Releases 8 and 9, the subframe allocation for the backhaul link in LTE networks operating with in-band Type 1 relay nodes is related to Multimedia Broadcast over a Single Frequency Network (MBSFN) subframes [5], which transport paging and synchronization data to the User Equipments (UEs) over blank subframes. The ratio between MBSFN and MRN-UEs access subframes, as well as the position of these subframes in the LTE radio frame, has a key impact on the relay performance.…”

“…In previous works, it has been concluded that the inclusion of MRN installed on the top of the vehicle, improves the global network performance, as in [3] [4] [5] [6]. However, these works only addressed the performance of LTE downlink connection [3][4] [5]. Besides, the performance of this new radio access paradigm in railway scenarios must be evaluated regarding the usage of accurate propagation channel models and specific resource assignment mechanisms for on-board train users, which have not been considered before [6] [7].…”

“…Besides, the performance of this new radio access paradigm in railway scenarios must be evaluated regarding the usage of accurate propagation channel models and specific resource assignment mechanisms for on-board train users, which have not been considered before [6] [7]. Some of these considerations have been taken into account in the evaluation of LTE downlink performance in HSR scenarios [5]. In this paper, the authors evaluate the performance of MRN radio access architecture deployment for LTE uplink in HSR environments.…”

Railway scenarios present several specific features that complicate the deployment of a radio communication network, especially for high speed trains. Nowadays, railway operators are evaluating the migration process from GSM-R to a new broadband system, like Long Term Evolution (LTE). In this paper, system-level simulations are carried out in order to evaluate overall network performance with Mobile Relay Node architecture for LTE uplink access in High Speed Railway scenarios. This implies developing specific tools for accurate characterization of such propagation environments.
