Group path mobile handover authentication method based on mobile relay

Abstract

The invention discloses a group path mobile handover authentication method based on a mobile relay, which is characterized by comprising the following steps of: S1, executing a stage of carrying out initial authentication; S2, executing a stage of carrying out switching authentication on the basis of a group path; S3, executing an internal switching process aiming at MMEs; S4, executing an inter-switching process aiming at the MMEs; S5, sending group switching command information; and S6, sending a group switching confirmation message. According to the group path mobile handover authentication method disclosed by the invention, the scheme is designed according to a 3GPP standard, and thus, communication equipment in the standard does not need to be changed, and the group path mobile handover authentication method can be applied to networks of all LTE-A mobile scenes; massive switching information can be integrated into one piece of group switching information, and signaling traffic between all the equipment and the MMEs is greatly saved, so that switching communication cost is greatly reduced, and signaling congestion on a link between a service network and a home network is reduced; and mutual authentication between a group of MRNs and a base station DeNB can be directly implemented, and all currently known attacks can be resisted to.

Description

technical field

[0001] The invention relates to the technical field of communication network security, in particular to a mobile relay-based group-to-path mobile handover authentication method. Background technique

[0002] With the development of the high-speed rail system, more passengers choose high-speed rail travel instead of airplanes, because the latter is more comfortable, less affected by weather factors, and energy-saving. Therefore, it is very important to solve the real-time communication on the high-speed rail to improve the travel experience of passengers. However, due to the Doppler shift effect caused by frequent base station switching and the penetration loss caused by high-speed driving on high-speed rail, the data rate in the high-speed rail communication system decreases and the energy consumption of user equipment (UE) increases. Moreover, when many UEs switch base stations at the same time, it is likely to cause signal congestion and increase the hando...
