Problems solved by technology

[0004] In the process of realizing the reporting of the above measurement results, the inventors have found that at least the following problems exist in the prior art: the RSRP and / or RSRQ measurement thresholds for ICIC report events in the prior art are fixed thresholds, but due to changes in the wireless environment (such as Added a building, or walked to the basement, etc.), the cell power will change, causing the cell boundary to change
The measurement threshold configured in the prior art cannot accurately determine whether the user equipment is at the edge of the cell when the cell boundary changes

Embodiment Construction

[0056] In a cell, user equipment at the center of the cell and user equipment at the edge of the cell have different levels of interference to neighboring cells, so the scheduling strategies and interference coordination strategies for the two are also different. Then, it becomes a key issue to accurately determine whether the location of the user equipment is at the center of the cell or at the edge of the cell. The embodiment of the present invention is to solve this problem.

[0057]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the presen...

Abstract

The embodiments of the present invention disclose a method, a device and a system for adjusting the measurement threshold of the user equipment (UE), which relate to mobile communication field, and are proposed to solve the problem in the prior art that the reporting threshold of the measurement of the UE can not exactly reflect the changes of the real radio environment when the cell boundary changes. In the method proposed by the embodiments of the present invention: whether the UE is at the edge position of the service cell is determined according to the received relevant information; the reporting threshold of the measurement of the UE in the service cell is adjusted to make the measurement threshold of the UE in the service cell accord with its position in the service cell, and the adjusted result is fed back to the UE in the service cell. The present invention is applied to mobile communication system.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method, device and system for adjusting the user equipment measurement report threshold. Background technique [0002] The data rate provided by the existing cellular mobile communication system is very different between the center of the cell and the edge of the cell, which not only affects the capacity of the entire system, but also causes great fluctuations in the quality of service obtained by users in different locations. The existing methods for demarcating the cell center and cell edge are as follows: Figure 12 As shown in the figure, the circular area marked by oblique lines in the figure is the edge of the cell, and the circular area marked by oblique lines within the edge of the cell is the center of the cell. At the cell edge, Inter-cell Interference (ICI) is an inherent problem in cellular mobile communication systems. For cell-edge users, the inter-cell...
