Method, device and system for controlling power of home Node B

Abstract

The embodiment of the invention discloses a method, a device and a system for controlling the power of a home Node B. The method for controlling the power of the home base station comprises the following steps of: determining that user equipment (UE) enters a micro-cell under the coverage of signals of the home Node B (HNB); determining that the UE does not have an authority to access to the HNB;acquiring a measurement report of the UE, wherein the measurement report comprises macro-cell signal quality information of the position of the UE; and determining that the signals of the micro-cell generate same frequency interferences to the signals of the macro-cell according to the macro-cell signal quality information, and reducing the transmitting power of the HNB. By applying the technicalscheme of the embodiment of the invention, when the unauthorized UE enters a coverage area of the micro-cell of the HNB, the transmitting power of the HNB is adjusted according to the signal quality of the macro-cell in which the UE is positioned so as to reduce the interferences caused by the HNB to the macro-cell and reduce drop-call phenomena of the unauthorized UE in the coverage area of the micro-cell of the HNB.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for power control of a home base station. Background technique [0002] With the rapid increase in the number of mobile communication users and the continuous improvement of user needs, mobile communication system equipment also presents a diversified development trend. As a miniaturized base station, HNB (Home NodeB, home base station) is aimed at application scenarios such as home, school, and enterprise. The network system based on HNB or HeNB can effectively improve indoor coverage, increase indoor access rate, reduce delay, and meet various user application requirements. At the same time, it can also reduce the load of macro base stations, so that the capacity of macro base stations is mainly used for outdoor or sports. medium users. [0003] HNB application scenarios include capacity expansion scenarios and supplementary coverage...

AI Technical Summary

Problems solved by technology

Since the operator may adopt a variety of frequency schemes, it is unavoidable that the HNB and the macro base station use the same frequency point, resulting in co-frequency interference between the HNB and the macro base station. The specific impact is as follows: when there is no access to the HNB When an authorized UE (hereinafter referred to as unauthorized UE) moves to the coverage area of ​​the HNB micro cell, due to the strong HNB signal, it will generate strong interference to the UE, and in severe cases, it will cause call drop, thus causing the coverage within the macro base station to be "dead".
