A measurement result reporting method and ue

Abstract

The embodiment of the present invention discloses a method for reporting measurement results and a UE. The method is applied to a high-speed railway mobile communication system. The method includes: the UE determines a pre-stored line to which the current travel line of the user belongs according to the historical switching path of the UE; Wherein, each pre-stored line is preset with a corresponding cell handover path; the UE searches for the target cell according to the cell handover path and the serving cell corresponding to the determined pre-stored line; the UE measures the target cell to obtain the measurement value of the target cell; The measurement value of the target cell is revised to increase the measurement value of the target cell; the UE reports the revised measurement value of the target cell to the access network device. The embodiment of the present invention can improve the handover success rate and reduce the number of dropped calls.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of mobile communication, and in particular to a method for reporting a measurement result and a UE. Background technique [0002] In a high-speed railway mobile communication system, user equipment (UE) moves with the high-speed railway at a speed of more than 200 kilometers per hour, so the UE needs to perform cell switching at high frequency. When using traditional signal quality measurement, reporting measurement results, and judging handover, because the UE is in a high-speed mobile state, its actual wireless environment changes drastically, often when the UE reports the measurement results of a neighboring cell to the access In the process of handover judgment by the access network equipment, the UE has already moved out of the serving cell, resulting in handover failure. In this way, the UE loses wireless coverage, causing call drop and affecting user experience. [0003] The...

When using traditional signal quality measurement, reporting measurement results, and judging handover, because the UE is in a high-speed mobile state, its actual wireless environment changes drastically, often when the UE reports the measurement results of a neighboring cell to the access In the process of handover decision made by the access network equipment, the UE has already moved out of the serving cell, resulting in handover failure. In this way, the UE loses wireless coverage, causing call drop and affecting user experience.
