摘要：Long term evolution (LTE) is replacing the 3G services slowly but steadily and become a preferred choicefor data for human to human (H2H) services and now it is becoming preferred choice for voice also. Insome developed countries the traditional 2G services gradually decommissioned from the service andgetting replaced with LTE for all H2H services. LTE provided high downlink and uplink bandwidthcapacity and is one of the technology like mobile ad hoc network (MANET) and vehicular ad hoc network(VANET) being used as the backbone communication infrastructure for vehicle networking applications.When Compared to VANET and MANET, LTE provides wide area of coverage and excellent infrastructurefacilities for vehicle networking. This helps in transmitting the vehicle information to the operator anddownloading certain information into the vehicle nodes (VNs) from the operators server. As per the ETSIpublications the number of machine to machine communication (MTC) devices are expected to touch 50billion by 2020 and this will surpass H2H communication. With growing congestion in the LTE network,accessing the network for any request from VN especially during peak hour is a big challenge because ofthe congestion in random access channel (RACH). In this paper we will analyse this RACH congestionproblem with the data from the live network. Lot of algorithms are proposed for resolving the RACHcongestion on the basis of simulation results so we would like to present some practical data from the livenetwork to this issue to understand the extent RACH congestion issue in the real time scenario.
