Problems solved by technology

That is, due to the introduction of MRN in the existing solution, the handover delay of the UE is additionally increased, which does not meet the ultra-low delay requirement in the 5G network
[0007] (3) Due to the deployment of small base stations in the 5G network, when the train is running at high speed, the service time of individual base stations to the MRN is very short, resulting in the MRN and the current base station entering the next base station without completing the handover, which may lead to discontinuity of user services performance and consume unnecessary switching overhead

Embodiment Construction

[0061] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0062] The present invention can ignore the time delay of the handover authentication between the MRN and the base station by performing the handover authentication in advance, and can optimize the communication overhead and calculation overhead generated during the pre-handover authentication process between a large number of MRNs and the base station by using the group handover, and introduce cooperative handover, which can Further reduce the communication overhead and calculation overhead in the group switching process.

[0063] The application principle of the present invention will be described in detail below in conjunc...

Abstract

The invention belongs to the technical field of communication network security, and discloses a group pre-handover authentication method based on a fixed path and a high-speed rail network communication platform, including: an initialization authentication stage; a group pre-handover authentication stage based on a fixed path; a group collaboration based on a fixed path Pre-handover authentication phase. The SDN server of the present invention can know the fixed track information of the train and the location information of the base station in advance, and know the next base station to be connected to the MRN. The SDN server assists the pre-handover authentication and key negotiation between the MRN and the next base station in advance; therefore, when the MRN enters the range of the next base station, it can directly communicate with the base station. All the MRNs on the train in the present invention form a group to perform switching authentication, which can reduce the switching cost; considering the high-speed movement of the train, a coordinated switching process is added to ensure the continuity of services and further reduce the switching cost. The present invention can resist all currently known attacks.

Description

technical field [0001] The invention belongs to the technical field of communication network security, and in particular relates to a group pre-handover authentication method based on a fixed path and a high-speed rail network communication platform. Background technique [0002] At present, the commonly used existing technologies in the industry are as follows: with the rapid development of science and technology, more and more users choose fast and convenient high-speed railways as a means of transportation. Due to the rapid mobility of high-speed rail, data transmission is affected by Doppler frequency shift effect, penetration loss, etc. In addition, in the high-speed rail network, when the train travels from the coverage area of ​​one base station to the coverage area of ​​another base station, a large number of user equipment UEs on the train need to perform handover authentication at the same time, resulting in a large amount of handover overhead, which may lead to ha...
