“…Network connectivity for moving vehicles has been widely studied in the context of railway communications [7] and Vehicular Ah-Hoc Networks (VANETs) [8]. In both cases, they use track-side access nodes to wirelessly communicate the moving vehicle with an infrastructure network, which we assume it already use a suitable handover capability [9], [10] in order to seamlessly transport traffic from the in-motion network to the infrastructure network.…”

International audienceIn this paper, we study the disconnection of a moving vehicle from a linear access network composed by cheap WiFi Access Points in the context of the telecommuting in massive transportation systems. In concrete, we analyze the probability for a user to experience a disconnection longer than a given time interval (t *) such that all ongoing communications between the vehicle and the infrastructure network are disrupted. We provide an approximation formula considering two scenarios (intercity bus and train). We then carry out a sensitivity analysis and supply a guide for operators when choosing the parameters of the networks. Last, we show that such systems are viable, as they attain a very low probability of long disconnections with a very low maintenance cost

“…Handover is one of the most challenging issues in HSR mobile communications, due to high handover frequency, group handover and QoS guarantees [15]. The literature [20] has presented an overview of the technical developments on handover in HSR mobile communications. Handover schemes are classified into seven categories according to the access technologies and network architectures.…”

“…This paper systematically reviews and evaluates the various studies performed in the area of HSR communication systems. There are also some survey papers discussing the research topics in HSR wireless communications, such as the network architectures [12,13], the handover schemes [20], and the channel characteristics and models [21,22]. Contrary to these surveys, this paper provides a comprehensible survey on HSR wireless communications from the perspective of RRM and optimization design.…”

High-speed railway (HSR) communications will become a key feature supported by intelligent transportation communication systems. The increasing demand for HSR communications leads to significant attention on the study of radio resource management (RRM), which enables efficient resource utilization and improved system performance.RRM design is a challenging problem due to heterogenous quality of service (QoS) requirements and dynamic characteristics of HSR wireless communications. The objective of this paper is to provide an overview on the key issues that arise in the RRM design for HSR wireless communications. A detailed description of HSR communication systems is first presented, followed by an introduction on HSR channel models and characteristics, which are vital to the cross-layer RRM design. Then we provide a literature survey on state-of-the-art RRM schemes for HSR wireless communications, with an in-depth discussion on various RRM aspects including admission control, mobility management, power control and resource allocation. Finally, this paper outlines the current challenges and open issues in the area of RRM design for HSR wireless communications.

“…In [27], an efficient Handover schemes and algorithm in high-speed mobile railway environments are proposed to reduce handover times and secure handover performance, meanwhile with less handover energy and resources. The solution has good energy saving effect in handover procedure, but which is a quite small proportion of entire railway cellular network, cannot solve the energy waste problem primarily.…”

Along with emerging increasing multimedia service need from the big amount of users in the train, wireless cellular railway network has big energy saving potential with its own specific characteristics, which is widely deployed over the world. Enhanced Multimedia Broadcast Multicast Service (E-MBMS) is a prevalent solution for high speed data handling. In this paper, to achieve an energy efficient solution for wireless cellular railway network, we proposed an optimal power control solution to adjust eNodeB's transmission power adaptively based on actual Signal to Interference plus Noise Ratio (SINR) for Multimedia Broadcast multicast service Single Frequency Network (MBSFN) at User Equipment (UE) side when provide E-MBMS. We established the system model and proposed the optimization algorithms to calculate the E-MBMS transmit power. We also designed the geometry group scheme to significantly reduce the calculation effort. And proposed the Mobility offset parameter to cope with high speed mobility of the train and variation of signal level. Finally, Simulation results showed that this solution can be a good way for high network energy efficiency and can dynamically adjust the output power for the multicast service in the wireless cellular railway communication network.
