Abstract

The invention discloses a data scheduling method utilized in a LTE rail traffic scenario. The data scheduling method is characterized by the following steps: using a TA parameter fed back by UE, and characteristics of a fixed movement path and a fixed regular motion of an in-train terminal to perform pre-determination, to enable the UE to enter a switching preparation state, in which the UE ensures, by employing a service labeling mechanism, a high scheduling priority for the most important service in UE services; and utilizing an interaction mechanism to notify a target base station to adopt the same scheduling method, so as to ensure performance of a main service being unaffected until completion of the switching process. As a result, the embodiment can be utilized to reduce a risk of reduced performance owing to being too slow to switch. The invention provides simple implementation, is efficient and accurate, does not need additional hardware, has a significant market value, and provides an important value in placing a local relevant industry in a leading position in the global market.

Description

technical field [0001] The present invention relates to the technical field of rail transit wireless communication, and more specifically, the present invention relates to a data scheduling processing method in an LTE rail transit scenario. Background technique [0002] As an important means and effective measures to solve traffic problems in big cities, urban rail transit system has the advantages of large transportation volume, fast speed, safety, punctuality, and comfort, and can drive the comprehensive development and utilization of urban land resources, which is of great significance to the long-term development of cities . At the same time, with the rapid development of information and communication technology to broadband, the demand for rail transit information construction is also increasing. As the key system of rail transit informatization, the train-to-ground wireless communication system of rail transit is mainly used to establish a two-way, stable, reliable, a...
