Embodiment Construction

[0032] Below in conjunction with accompanying drawing, the inventive method is described in further detail:

[0033] figure 1It is the networking framework required by the LTE switching method based on dual-antenna linkage proposed by the present invention. An LTE access antenna is respectively arranged at the front and rear of the train, and is respectively connected to the corresponding modem interface in the on-board relay gateway. Into the module, the on-board relay gateway uses wireless access equipment to cover Wi-Fi or other wireless signals to the inside of the train for wireless device access, collects the network messages of passengers and trains, encapsulates them into LTE message format, and It is forwarded to the mobile base station through the front / rear antenna to provide Internet services for passengers.

[0034] When the head of the train enters the overlapping handover zone between the base stations, the antenna at the head of the train performs the switchin...

Abstract

The invention discloses an LTE (Long Term Evolution) switching method based on high-speed train double-antenna linkage, and mainly solves the problem that in the prior art, the switching success rateis low and the network quality is influenced due to the fact that a TD-LTE system moves too fast in a high-speed railway environment. According to the scheme, the method comprises the following steps:1, ; an LTE antenna and an access control unit which work independently are arranged at the head and the tail of a high-speed rail train respectively; the vehicle head antenna is switched firstly; then, the consistency and the determinacy of the head-tail switching environment of the train are utilized; according to the method, the vehicle head antenna switching data is synchronized to the vehicle tail antenna, and the related parameters are adjusted and optimized based on the evaluation result when the vehicle tail antenna is switched according to the evaluation of the switching effect of the vehicle head antenna, i.e., the switching process and data of the vehicle tail antenna are dynamically adjusted and then the switching is carried out, so that a better switching effect is obtained.According to the invention, the switching performance of a mobile user in a high-speed motion scene is effectively improved, and the overall network service quality of a train is optimized.

Description

technical field [0001] The invention belongs to the technical field of communication, relates to wireless communication technology, and further relates to the switching of dual-antenna linkage of high-speed rail trains, specifically a high-speed rail LTE switching method based on dual-antenna linkage, which can be used in high-speed rail mobile communication systems. Background technique [0002] With the rapid development of high-speed railways, high-speed railways have become one of the main modes of transportation for people's daily travel. Passengers' demand for mobile networks has also developed from a single service such as traditional text messaging and voice to short video, real-time chat, multimedia, etc. A variety of comprehensive entertainment services have put forward higher and higher requirements for network bandwidth and delay. [0003] The traditional dedicated railway network uses the GSM-R (Global System for Mobile Communications-Railway) wireless communica...
