Embodiment 1

[0151] Figure 14 It is a flow chart of a faulty cell self-healing method according to an optional embodiment of the present invention, such as Figure 14 As shown, the method includes the following steps:

[0152] Step S1402, start the self-healing function. The self-healing function can be activated through the base station where the cell is located.

[0153] Step S1404, monitoring self-healing alarms and KPIs. The self-healing alarms and KPIs of multiple cells are monitored in real time through the base station where the cell is located, where the KPI may include multiple indicators, such as the number of handovers and handover success rate of each cell.

[0154] Step S1406, judging the cell failure type. The fault type of the cell can be determined through the self-healing alarm and KPI of each cell, wherein, when it is judged that the cell does not meet the condition of a faulty cell, return to step S1404. There may also be many kinds of cell failure types. In this o...

Embodiment 2

[0165] Figure 15 is an effect diagram of compensation for a faulty cell by a compensation cell according to an optional embodiment of the present invention, as shown in Figure 15 as shown, Figure 15 The area 1 drawn by the solid line is the fault cell, and the areas 2 and 3 drawn by the solid line are the compensation cells. When a fault occurs in cell 1, the area covered by cell 1 will have a blind area. At this time, compensation cell 2 and compensation cell 3 respectively adjust the downtilt angle of the electronically adjustable smart antenna to increase the size of compensation cell 2 and compensation cell 3. Covered range, so as to achieve compensation for the area covered by the faulty cell. from Figure 15 It can be seen from the figure that after adjusting the downtilt angle of the electronically adjustable smart antenna, the range covered by the compensation cell 2 and the compensation cell 3 is increased, and the coverage after the increase is as follows Fig...

Embodiment 3

[0167] Figure 16 is a schematic diagram of successful self-healing compensation of a faulty cell according to an optional embodiment of the present invention, such as Figure 16 shown, including the following steps:

[0168] Step S1602, enabling the cell self-healing function. In this optional embodiment, the cell self-healing function may be enabled by the base station 1 .

[0169] Step S1604, monitoring cell self-healing alarms and KPIs. The self-healing alarms and key performance indicators KPI of multiple cells can be monitored simultaneously through the base station 1 . In this optional embodiment, the KPI may include at least one of the following: handover times and handover success rates of multiple neighboring cells of the faulty cell within a preset time period.

[0170]Step S1606, satisfying the condition of the faulty cell. The base station 1 can determine whether the cell meets the condition of a faulty cell according to the monitored self-healing alarm and KP...

Abstract

The invention provides a cell self-healing compensation method and a compensation device. The method comprises steps: a compensation cell for a fault cell is determined; and a message is sent to a base station where the compensation cell is, wherein the message is used for indicating to use the compensation cell to compensate the fault cell. Thus, the problem that a blind area appears in a cell coverage area caused by cell fault or fault recovery failure in a related technology can be solved, the technical effect of improving the experience feeling of the user is thus achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a cell self-healing compensation method and device. Background technique [0002] With the deepening of Long Term Evolved (referred to as LTE) commercialization, more and more functions of self-organizing networks (Long Term Evolved Self-Organized Networks, referred to as LTE SON) are purchased and used by operators, among which self-healing The function is one of the most widely used SON functions. According to the different service status of the cell, the self-healing function of LTE SON can be divided into the following three categories: self-healing of the cell out of service, self-healing of the sleeping cell, self-healing of the performance cell, and self-healing The process is divided into three stages: self-healing diagnosis, self-healing recovery, and self-healing compensation. When self-healing recovery fails, self-healing compensation will be performed. [0003] The ...
