Title:
DATA SCHEDULING METHOD UTILIZED IN LTE RAIL TRAFFIC SCENARIO
Document Type and Number:
WIPO Patent Application WO/2018/107909
Kind Code:
A1
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.
