Example 1
The embodiment of the invention provides an automatic blind-supplementing capacity-expanding method which is applied to a small base station, please refer to fig. 1, and the automatic blind-supplementing capacity-expanding method is described in detail below.
110, sending measurement configuration information to the accessed direct connection terminal.
And 120, receiving a measurement report generated by the direct connection terminal.
The small base station is connected with a direct connection terminal (UE), the small base station is started according to default configuration of the small base station, the small base station transmits network signals to the terminal for communication, and small transmitting power is set when the network signals are transmitted, so that interference to the current network of each frequency point cell is avoided.
The small base station transmits measurement configuration information to the connected direct-connection terminal according to preset base station configuration, and the measurement configuration information is transmitted based on preset configuration of the small base station, and based on a measurement event in the measurement configuration information, the small base station can trigger the direct-connection terminal to sweep frequency to measure the network state information of the current position of the same-frequency cell with the same frequency point as the small base station and generate a measurement report. The measurement configuration information comprises a frequency point of the small base station and a measurement event, wherein the measurement event is one of an A1 event, an A2 event, an A3 event, an A4 event and a B1 event, and particularly the corresponding measurement event is issued based on the preset configuration of the small base station; and the measurement event has been predetermined to the signal to be acquired, the corresponding signal and the signal strength thereof can be acquired according to the measurement event, for example, the signals such as Reference Signal Received Power (RSRP), reference Signal Received Quality (RSRQ) and the corresponding signal strengths thereof can be acquired.
The small base station (micro base station) adopted in the embodiment is base station equipment applied to an office environment or other small coverage environments, has the characteristics of small volume, low energy consumption and the like, and can enable operators to provide attractive services with higher data rate and lower cost; the small base station is generally mainly used for blind supplement and capacity expansion of the macro base station. For example, the small base station can be selected from a movable small base station or a small base station which is loaded on a moving tool (vehicle, sliding rail and the like) to move, and the small base station can be started and simultaneously can move, so that the current network state information of a plurality of positions can be measured.
130, analyzing the network state information of the current position of the same-frequency cell according to the measurement report, and determining a target task to be executed at the current position, wherein the target task is a blind supplement task or a capacity expansion task.
In one possible embodiment, as shown in fig. 2, step 130 may specifically include the steps of:
131, comparing whether the network signal strength in the measurement report is less than or equal to a predetermined signal strength threshold.
132, if the network signal strength is less than or equal to the predetermined signal strength threshold, determining that the target task to be executed at the current position is a blind supplement task.
133, if the network signal strength is greater than the predetermined signal strength threshold, comparing whether the number of handover requests in the measurement report is greater than or equal to the predetermined request threshold.
134, if the number of switch-in requests is greater than or equal to the predetermined request threshold, determining that the target task executed at the current location is a capacity expansion task.
The direct connection terminal can measure and collect related signals and signal strength of the current position of the same-frequency cell based on the signals and the signal strength of the signals which are required to be collected and are regulated by the measurement event in the measurement configuration information, generate a measurement report and send the measurement report to the small base station.
After receiving the measurement report, the small base station analyzes the current network state information of the current position of the same-frequency cell according to the measurement report, namely, compares whether the network signal strength in the measurement report is smaller than or equal to a preset signal strength threshold value according to the network signal and the signal strength thereof acquired in the measurement report, if the network signal strength is smaller than or equal to the preset signal strength threshold value, the condition that the coverage degree of the 5G signal at the current position is weaker is a blind area, and blind compensation treatment is needed, so that the target task to be executed at the current position is determined to be a blind compensation task. In addition, the small base station can be continuously moved, and in the process, the small base station moves and measures the signal intensity of all positions of the same-frequency cells, so that the blind area range is determined.
If the network signal strength is greater than the preset signal strength threshold, the 5G signal coverage condition at the current position is good, and whether the number of switching-in requests in the measurement report is greater than the preset request threshold is compared; if the number of the switching-in requests is greater than a preset request threshold, indicating that the current position is a busy zone and capacity expansion processing is needed, so that the target task to be executed at the current position is determined to be a capacity expansion task; in addition, the small base station can be continuously moved, and the small base station can be used for measuring the signal strength of all the positions of the same-frequency cells in a moving way, so that the busy area range is determined.
And if the number of the switching-in requests is smaller than the preset request threshold, the mobile small base station goes to other positions, and the measurement configuration information is issued again to trigger the direct-connected terminal to continuously measure the current network state information at other positions of the same-frequency cell.
In a possible implementation, as shown in fig. 3, this embodiment further includes step 150: and if the measurement report generated by the direct connection terminal is not received, determining that the target task to be executed at the current position is a blind supplement task. And if the measurement report generated after the direct-connected terminal does not receive the current network state information of the same-frequency cell at the current position of the same-frequency cell of the same frequency as the small base station is measured according to the frequency point sweep of the small base station in the received measurement configuration information, determining that the target task to be executed at the current position is a blind supplement task.
Specifically, if the small base station does not receive the measurement report of the direct-connected terminal after the measurement configuration information is issued to trigger the direct-connected terminal to sweep the frequency to measure the network state information of the current position of the same-frequency cell, the situation that the 5G signal of the current position is covered with the loss is indicated, the blind area is formed, and a blind compensation task is needed.
140, executing the corresponding target task at the current position.
In a possible implementation, when the target task is a blind-complement task, as shown in fig. 4, step 140 may specifically include the following steps:
141, extracting preset same-frequency related configuration.
And 142, reconstructing the cell at the current position according to the same-frequency related configuration, and re-transmitting measurement configuration information to the direct connection terminal.
The small base station extracts the pre-stored same-frequency related configuration corresponding to the same-frequency cell, namely the same-frequency cell configuration, rebuilds the cell according to the same-frequency cell configuration in the determined current position or blind area range, and when the cell rebuilding is completed, the small base station sends measurement configuration information to the direct-connected terminal again to trigger the direct-connected terminal to carry out sweep frequency measurement on the rebuilt cell and the network state information of the current network.
In a possible implementation, when the target task is a capacity expansion task, as shown in fig. 5, step 140 may specifically include the following steps:
and 143, extracting preset inter-frequency correlation configuration.
And 144, reconstructing the cell at the current position according to the inter-frequency related configuration, and re-transmitting measurement configuration information to the direct-connection terminal.
The small base station extracts pre-stored different-frequency related configuration different from the same-frequency cell frequency point, namely different-frequency cell configuration, rebuilds the cell according to the different-frequency cell configuration in the determined current position or busy area range, and when the cell rebuilding is completed, the small base station sends measurement configuration information to the direct connection terminal again to trigger the direct connection terminal to carry out sweep frequency measurement on the rebuilding cell and to obtain network state information of the current network.
In a possible implementation, as shown in fig. 6, after the measurement configuration information is sent to the direct connection terminal again, the method further includes the following steps:
and 145, detecting whether the reestablished cell has an access current network terminal.
146, when the reestablished cell has an access current network terminal, the current network terminal is based on the current network terminal to collect the same-frequency signal power and the noise power, the signal to noise ratio is calculated according to the same-frequency signal power and the noise power, and when the signal to noise ratio is greater than or equal to a preset signal to noise ratio threshold, the transmitting power of the small base station to transmit the same-frequency signal is increased; when the signal-to-noise ratio is less than a predetermined signal-to-noise ratio threshold, the transmit power of the base station is reduced.
147, when the reestablished cell is not accessed to the current network terminal, the transmitting power of the small base station is not adjusted.
Detecting whether the reestablished cell has an access network terminal, and transmitting a network signal to the terminal for communication by the small base station when the reestablished cell has the access network terminal. In order to avoid that the set transmitting power is too large when transmitting network signals, interference can be generated to the current network of each frequency point cell, the embodiment sets a self-adaptive power adjustment algorithm, calculates the proportion of the same-frequency signal power and the noise power of the current network terminal, namely the signal to noise ratio, according to the same-frequency signal power and the noise power measured by the current network terminal, and self-adaptively adjusts the transmitting power according to the signal to noise ratio, so as to seek balance in blind compensation and interference; when the signal-to-noise ratio is greater than or equal to a preset signal-to-noise ratio threshold, increasing the transmitting power of the small base station transmitting network signals (same-frequency signals); when the signal-to-noise ratio is smaller than a preset signal-to-noise ratio threshold, reducing the transmitting power of the base station, namely that the same-frequency signal interference degree is higher than the preset interference threshold, reducing the transmitting power of the base station transmitting network signals according to a certain step, wherein the specific step can be set according to actual conditions; when the reconstructed cell is not accessed by the current network terminal, the transmitting power is not adjusted; thereby realizing the self-adaptive adjustment of the transmitting power of the small base station.
In a possible implementation manner, as shown in fig. 7, if the co-frequency cell starts the function of automatic neighbor relation, after receiving a measurement report generated after the direct-connected terminal measures the current network state information of the co-frequency cell at the same frequency as the small base station according to the small base station frequency point sweep in the received measurement configuration information, the method further includes the following steps:
160, automatically adding or deleting the adjacent cell relation of the same-frequency cells according to the current network state information in the measurement report.
And 170, searching the adjacent cells according to the adjacent cell relationship, and receiving a switching-in request of switching the adjacent cells to the same-frequency cell.
When an automatic neighbor relation function (ANR) is started in the same-frequency cell, the small base station correspondingly adjusts the neighbor relation of the same-frequency cell based on the current network state information in the measurement report, namely searches for a newly increased neighbor according to the current network state information, automatically adds the neighbor relation or searches for a failure neighbor, and deletes the neighbor relation of the failure neighbor. The ANR function is an ANR function of a multiplexing base station protocol stack, so that the self-configuration and self-optimization of the neighbor relation can be realized, the working strength of network planning and optimizing personnel is reduced, and the network construction investment and the operation cost are reduced.
When the cell relation is newly added or deleted by the ANR function at the current position, the cell can search the neighbor cell of the same-frequency cell according to the neighbor cell relation, receive a switching-in request for switching the neighbor cell to the same-frequency cell, and send the switching-in request for switching the same-frequency cell to the neighbor cell. Through the neighbor relation, the situation of call drop between the same-frequency cell and the neighbor can be avoided, and the switching success rate is increased for capacity expansion processing.
According to the invention, the small base station transmits measurement configuration information, receives and analyzes a measurement report of the direct connection terminal for measuring the current network state information of the same-frequency cell with the same frequency as the small base station, judges the coverage intensity of the 5G signal, determines and executes the target task of blind supplement or capacity expansion to be carried out at the current position, and realizes the automatic judgment and execution of the task of blind supplement or capacity expansion, thereby improving the coverage rate of the 5G signal, avoiding the call drop caused by abnormal coverage of the 5G signal or abnormal switching, and improving the user satisfaction.
