Embodiment Construction

[0037] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0038] The HNB pilot power control method proposed by the present invention is based on services, and can allocate pilot power according to specific service types. Such as figure 1 As shown, the present invention is mainly applicable to the situation where the mobile terminal is in the same coverage area of ​​the macro base station and the HNB.

[0039] figure 2 It is a schematic flow chart of the HNB pilot power control method of the present invention, as shown in the figure, the method includes:

[0040] Step 101, initialize the HNB and establish a communication connection with the mobile terminal.

[0041] After the HNB is powered on, the HNB is initialized, wherein a fixed value P is set for the pilot power setup , the pilot power can meet 80-90% of the indoor coverage requirements, for example, if the initi...

Abstract

The invention discloses a control method for pilot frequency power of Home Node B (HNB). The method comprises the following steps: initializing HNB, and establishing the communication linkage with a mobile terminal user; determining the setting type of the current data communication service; if the current data communication service is the first type, increasing the current pilot frequency power when the current signal-to-noise ratio is smaller than the preset threshold value; and if the current data communication service is the second type, decreasing the current pilot frequency power when the current signal-to-noise ratio is greater than or equal to the preset threshold value. The invention also provides a control system for pilot frequency power of the HNB, which can reasonably distribute the resources of the pilot frequency power.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and system for controlling pilot power of a home base station (HNB, Home NodeB). Background technique [0002] With the rapid development of the third generation digital communication (3G, 3rd Generation) technology and the reorganization of telecom and mobile operators, seamless signal access technology and indoor coverage technology in network construction have increasingly become the focus of operators' close attention. . Good network coverage, especially indoor coverage, is the key to the rapid development of mobile communications. Under the background of this demand, HNB, as a small, low-power base station, has already received keen attention and favor from operators and equipment manufacturers at home and abroad. On the one hand, HNB can quickly solve the indoor coverage problem of signals at a relatively low cost, provide users with high-speed data communicatio...
