Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, fig. 1 is a network structure diagram applicable to the embodiment of the present invention, and as shown in fig. 1, the network structure diagram includes a server 11 and a base station 12, the specific type of the server 11 is not limited in the embodiment of the present invention, the server 11 may establish communication with the base station 12, and the base station 12 may be a macro station, such as an LTE eNB, a 5G NR NB, or the like, and may also be a micro base station.
As shown in fig. 2, an embodiment of the present invention provides a method for adjusting a base station threshold, including the following steps:
and step 201, acquiring an uplink background noise measured value.
It should be noted that background noise, also called background noise, refers to noise other than useful signals in the system, and in general, the higher the background noise is, some weak coverage signals will be submerged under the background noise, so that the receiving sensitivity of the base station is reduced, and the call quality is poor. The NPRACH thresholds of the cells on the NB-IoT base station side are configured manually according to the uplink background noise, and in each cell on the NB-IoT base station side, the fluctuation of the uplink background noise may be large along with the change of the wireless environment caused by the expansion and contraction or the transformation of the wireless system, or the adjustment of the antenna feed system, and once the change occurs, the previously configured NPRACH thresholds may become unreasonable and need to be changed. It should be noted that the uplink background noise measurement value may be understood as an uplink background noise of a radio environment of a cell covered by a base station, which is acquired by the base station through an antenna receiver.
Optionally, the current NPRACH threshold of the narrowband physical random access channel is updated to the NPRACH threshold corresponding to the uplink background noise measurement value according to the uplink background noise measurement value; the method comprises the following steps:
and if the absolute value of the difference value between the uplink bottom noise measured value and the uplink bottom noise historical measured value is larger than the uplink bottom noise fluctuation threshold, updating the NPRACH threshold of the current narrow-band physical random access channel to be the NPRACH threshold corresponding to the uplink bottom noise measured value.
The uplink background noise historical measurement value can be understood as a certain value or an average value of certain values in the uplink background noise measurement values acquired by the base station, and can also be understood as a minimum value, a middle value or a maximum value in certain values; the uplink bottom noise fluctuation threshold can be understood as a preset threshold; the NPRACH threshold corresponding to the uplink noise floor measurement value may be understood as an NPRACH threshold corresponding to the uplink noise floor measurement value according to a change of the uplink noise floor measurement value.
According to the embodiment of the invention, the NPRACH threshold can be adapted and adjusted in time by automatically collecting and counting the uplink background noise measured value and then according to the change condition of the uplink background noise; therefore, manual operation can be greatly reduced, and a large amount of labor can be saved.
As shown in fig. 3, another method for adjusting a base station threshold provided in the embodiment of the present invention includes the following steps:
301, acquiring uplink background noise measurement values every other preset period.
The uplink background noise measured value is obtained at intervals of a preset period, so that the uplink background noise measured value is not required to be obtained in real time almost every minute and every second, and resources are saved.
And step 302, calculating an uplink background noise average value of the uplink background noise measured values obtained within the preset time.
Setting a reasonable period, and calculating the average value in the preset time, so that the change condition of the uplink background noise can still be ensured to be obtained under the condition of not wasting too many resources; it should be noted that the preset time may be a period of time set by an operation maintenance worker according to the judgment of the operation maintenance worker, and the preset time is longer than the preset period, for example: setting a preset period to be 10 minutes and a preset time to be 24 hours; in this way, the base station acquires uplink background noise measurement values every 10 minutes, and calculates the average value of the uplink background noise acquired within 24 hours.
And 303, if the absolute value of the difference value between the uplink background noise average value and the uplink background noise historical measurement value is greater than the uplink background noise fluctuation threshold, updating the current NPRACH threshold to be the sum of the current NPRACH threshold and the difference value between the uplink background noise average value and a preset threshold.
It should be noted that the preset threshold may be a constant value, and for the uplink 15KHz subcarrier interval, the value is-128; this setting may adjust the NPRACH threshold of the cell of the NB-IoT base station to a more reasonable NPRACH threshold, which is a preferred setting rule relative to other setting rules.
The updating of the current NPRACH threshold is the sum of the current NPRACH threshold and the difference between the uplink background noise average value and a preset threshold, and may be understood as updating the current NPRACH threshold + of the current NPRACH threshold (current uplink background noise average value — theoretical uplink background noise value). For example, if the current NPRACH threshold is 5, the current uplink background noise mean value is-110, and the theoretical uplink background noise value is-128, then the current NPRACH threshold should be updated as: 5+ (-110+128) — 23, i.e. the current NPRACH threshold should be updated from 5 to 23.
It should be noted that the threshold policy message is mainly used for more flexibly adjusting services for an operator, the server may be a server of an Operation and Maintenance Center (OMC), and an Operation and Maintenance worker may preset NPRACH threshold parameter policies such as the uplink background noise fluctuation threshold, the preset time, the initial NPRACH threshold, and the preset initial value based on needs and judgment at the OMC, for example, the preset initial value may be 0; on the basis that the NB-IoT base station automatically acquires the uplink background noise and automatically updates the NPRACH threshold according to the acquired uplink background noise, operation and maintenance personnel can quickly adjust and update the NPRACH threshold according to various conditions or requirements by performing simple operation on an OMC background interface, so that the NPRACH threshold parameter can be adaptively adjusted in time along with the change of a wireless environment.
And 305, after updating the current NPRACH threshold to be the current NPRACH threshold plus the difference value between the uplink background noise average value and a preset threshold, updating the uplink background noise historical measurement value to be the uplink background noise average value.
It should be noted that such setting can provide more accurate information and thus can be adjusted to a more reasonable NPRACH threshold.
Optionally, the uplink background noise measurement value is an uplink background noise measurement value of an idle cell;
the method further comprises the following steps:
and after updating the current NPRACH threshold to be the sum of the current NPRACH threshold and the difference value between the uplink background noise average value and a preset threshold, sending an NPRACH threshold updating message to the server, wherein the NPRACH threshold updating message carries the updated current NPRACH threshold.
According to the embodiment, the uplink background noise measurement value of the base station in the idle state cell, namely when no service runs, is collected through statistics, so that the uplink background noise can be measured more accurately, and a more reasonable basis is provided for setting or updating the NPRACH threshold. In addition, after the NPRACH threshold is updated, the updated threshold parameter is reported to a server, for example, a server of the OMC, so that the latest NPRACH parameter can be provided and collected for a background operation and maintenance person, and on the basis that the base station automatically adapts to the change of an external infinite environment to update and adjust the base station threshold, the NPRACH threshold parameter can be set in time by combining with the operation and maintenance person according to the judgment of the base station or the requirement of an operator, so that the NPRACH threshold can be set more flexibly, conveniently and reasonably.
According to the embodiment of the invention, the uplink background noise measurement value is automatically obtained at intervals of a fixed preset period within the preset time, and the NPRACH threshold can be timely adapted and accurately adjusted on the premise of saving a large amount of resources according to the change condition of the uplink background noise; in addition, the NPRACH threshold can be adjusted more flexibly and reasonably by combining the threshold strategy message sent by the server and various configuration strategies carried by the threshold strategy message; therefore, manual operation can be greatly reduced, and a large amount of labor can be saved.
