Abstract

The invention discloses a safety switching method of a high-speed train target base station based on relay station auxiliary. The method comprises the following steps: (1) selecting a to-be-accessed target base station; (2) interacting switching preparation message by a relay station and the target base station through the current base station before entering the coverage range of the target basestation, accomplishing the new address configuration by the relay station and the current base station, thereby accomplishing the bidirectional authentication and the session key negotiation with thetarget base station; and (3) after entering the coverage range of the target base station, accomplishing the location registration of the relay station and the connected user equipment, and executingthe link layer switching to activate the new connection. Through the base station switching method disclosed by the invention, the forward security can be satisfied, the node forgery attack can be effectively prevented, the denial of service attack is prevented, the replaying attack is resisted, the computing efficiency is high, and the good safety protection is adopted for the confidentiality andthe integrity of the signaling message.

Description

technical field [0001] The invention relates to the technical field of base station switching, in particular to a method for safely switching target base stations of high-speed trains based on relay station assistance. Background technique [0002] In recent years, vehicle-to-ground wireless communication in high-speed railway scenarios has received extensive attention. The main problem faced by high-speed mobile train communication is fast and frequent base station switching. The base station (Evolved NodeB, eNodeB) is limited by its fixed location and transmission power, which causes the user equipment (UE) on the train to pass through multiple cells during the call. The train is an environment where people are relatively concentrated. When the train passes through the overlapping area, all UEs in the train undergo group switching at the same time. A large number of UEs sending switching requests will cause signaling storms, resulting in system congestion or even paralysi...
