Method for setting measuring configuration during base station and user equipment (UE) switching

Abstract

The invention provides a method for setting measuring configuration during base station and user equipment (UE) switching. The method for setting the measuring configuration comprises the following steps of: receiving a switching request message, wherein the switching request message comprises resident cell information which reflects the displacement situation of a wireless terminal; determining a parameter value for representing the movement speed of the wireless terminal according to the resident cell information; setting the measuring configuration according to the parameter value, determining the measuring configuration as periodic measurement when the parameter value is more than or equal to a first threshold value and determining the measuring configuration as event triggering measurement when the parameter value is less than or equal to a second threshold value; and sending a switching response message so as to allow a source base station to set the measuring configuration of the wireless terminal according to the switching response message, wherein the switching response message comprises the measuring configuration. In the embodiment of the invention, appropriate measuring configuration is set according to the movement situation of the wireless terminal, so that the situations of communication interruption during high-speed movement of the wireless terminal and the increase of network overhead during low-speed movement are reduced.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and in particular to a method for setting measurement configuration when a base station and a UE are switched. Background technique [0002] In the LTE mobile communication network, the movement of the wireless terminal UE or the change of the surrounding environment may cause signal fading, which is the main reason for starting the wireless terminal to switch between base stations. The base station starts the handover process depending on the measurement report of the wireless terminal, and the base station can initiate a handover to a neighboring cell with the best signal according to the content of the measurement report. [0003] In the prior art, the base station sets a measurement configuration for the wireless terminal in advance, and the wireless terminal sends a measurement report to the base station according to the measurement configuration. For example, if the me...

[0004] However, the inventor found in the process of realizing the present invention that if the moving speed of the wireless terminal is constantly changing, it will affect the number of detection times and detection results of the wireless terminal on the signal of the adjacent cell, and further affect the handover between base stations. When the base station is handed over, if the target base station still adopts the measurement configuration of the source base station, the communication interruption of the wireless terminal or the increase of invalid network overhead may be caused due to the inaccurate measurement configuration.

[0005] For example, a wireless terminal is handed over from base station A to base station B, and then from base station B to base station C. During two consecutive handovers, the speed of the wireless terminal changes from high to low, and the measurement configuration set by base stations A and B may be periodic However, when switching to base station C, since the speed of the wireless terminal is already low, the signal quality in the cell is relatively stable, so there is no need for periodic measurement, as long as there is an event trigger to measure, and if base station C continues to use The measurement configuration of base station B is periodic measurement, which will add additional invalid network overhead and reduce the operating efficiency of the network

If the speed of the wireless terminal changes from small to large, the event-triggered measurement configured by the source base station for low speed is no longer applicable to the case of high wireless terminal speed, which may cause communication interruption
