Abstract
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.
Highlights
Wireless cellular communication network are currently experiencing surging traffic load and energy consumptions
Compared with a public mobile cellular network, a wireless communication network deployed for railway can be characterized by specific chain structure, high speed mobility, high security requirement, frequent and continuous handover, predicable traffic aligned with train schedule and the big group of users concentrated in the train
There is no direct related work to design efficient Enhanced Multimedia Broadcast Multicast Service (E-MBMS) transmission solution by jointed consideration of special challenges and opportunities from railway scenario for green communication in cellular railway network
Summary
Wireless cellular communication network are currently experiencing surging traffic load and energy consumptions. Compared with a public mobile cellular network, a wireless communication network deployed for railway can be characterized by specific chain structure, high speed mobility, high security requirement, frequent and continuous handover, predicable traffic aligned with train schedule and the big group of users concentrated in the train. The first one is how to make sure the transmit power for the whole railway cellular network is the lowest To cope with this challenge, a new power control algorithm based on the actual SINR was proposed to achieve the best network energy efficiency of the whole network. & To the best of our knowledge, this is the first paper to propose an energy efficient solution for EMBMS service in a green cellular railway network;.
