Embodiment 1

[0025] see figure 1 , this embodiment shows a base station that can control a terminal to measure a cell according to a measurement priority of a frequency point. When the terminal is located at the edge of the current cell and cell handover may occur, the base station can control the terminal to measure neighboring cells according to the measurement priority set by the base station for the frequency point through the measurement configuration information delivered to the terminal. In this way, the base station controls the order in which the terminal measures the cells, and the measurement report that the terminal first feeds back to the base station is the measurement report of the cell with a higher measurement priority. When the base station controls the terminal to perform cell handover, the handed over cell is a cell with a higher measurement priority among neighboring cells. Instead of the prior art, the terminal randomly measures the first cell in the neighboring cell...

Embodiment 2

[0038] see figure 2 , this embodiment shows a terminal that can receive the measurement configuration information delivered by the base station in Embodiment 1, and sequentially switch neighboring cells according to the measurement configuration information.

[0039] The terminal in this embodiment includes: a receiving module 21, configured to receive the measurement configuration information of each neighboring cell of the current cell sent by the base station, and the measurement configuration information includes the measurement priority of each frequency point where each neighboring cell is located; a measurement module 22, configured to The order of measurement priority in the measurement configuration information of each neighboring cell is measured for each neighboring cell.

[0040] Generally, the base station can obtain the position of the terminal in the current cell (ie, the serving cell) according to the data interaction with the terminal. When the terminal is lo...

Embodiment 3

[0052] see image 3 , this embodiment shows a measurement control method, which is applicable to the base station in Embodiment 1, including:

[0053] S301. When the terminal is located at the edge of the current cell, configure measurement configuration information for the terminal; where the measurement configuration information is used for the terminal to measure each neighboring cell of the current cell, including the measurement priority of the frequency point where each neighboring cell is located; measure Priority is used for the terminal to measure neighboring cells according to the order of measurement priority;

[0054] S302. Send the measurement configuration information to the terminal.

[0055] In this embodiment, what is configured in S301 is the measurement configuration information of each neighboring cell of the current cell, that is, each neighboring cell has corresponding measurement configuration information. It can be understood that there may be inacces...

Abstract

The invention discloses a base station, a terminal, a measurement control method and a measurement method. In the invention, the base station can configure measurement configuration information for the terminal when the terminal is located at an edge position of a current cell, wherein the measurement configuration information is used for measuring each neighboring cell of the current cell and comprises measurement priority of a frequency point where each neighboring cell is; the measurement priority is used for measuring the neighboring cells according to a descending order of the measurementpriorities; after the base station sends the configured configuration information to the terminal, the terminal can measure the neighboring cells according to the descending order of the measurementpriorities configured by the base station and can preferentially send a measurement report of the cell with high measurement priority to the base station, thus, the base station can realize switchingthe terminal to the cell with high measurement priority. Relative to the existing technology, by application of the scheme provided by the invention, the base station can effectively control a measurement order of the terminal, and an effect of controlling the terminal to be switched to an ideal cell is realized.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a base station, a terminal, a measurement control method and a measurement method. Background technique [0002] In an LTE (Long Term Evolution) communication system, handover of a UE (User Equipment, user equipment) can ensure service continuity when the UE moves between different cells. The handover of the UE is based on the UE's measurement of neighboring cells. Only the neighboring cells whose measured signal quality meets the conditions configured by the base station are allowed to be used as the handover target cell by the UE. In the LTE system, UE measurements are based on frequency points, and each frequency point is called a measurement object. The base station configures a measurement object, and the UE measures all cells under the frequency point. [0003] In the case that the base station configures multiple measurement objects, the protocol of whi...
