Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Example one
An embodiment of the present invention provides a threshold adjustment method, which is applied to a threshold adjustment device, where the threshold adjustment device may be a part of a server or may be a separate device, as shown in fig. 1, and the method includes:
Here, the information of each sampling point may be obtained from a network management system, and the sampling points are preset by network management personnel. The network management system is a distributed network application system with software and hardware combined and software as main components, and aims to manage the network and enable the network to run efficiently and normally. The method is an important means for ensuring the reliable operation of the network, and a network administrator comprehensively monitors the network through a network management system.
The primary serving cell level information of the sampling point may include measurement information (MR), and the coverage of the network may be known through analysis of the MR information. For example, when a network access or call service is performed in a network, a mobile phone may continuously report MR information of a network signal to a base station side, and the base station side may know a coverage condition of the network by collecting the MR information, thereby providing a basis for network optimization.
And 102, determining a first ratio of the sampling points smaller than the pilot frequency threshold according to the level information of the main service cell of each sampling point.
Specifically, the total sampling point number is determined according to each sampling point; determining the number of sampling points of which the main service cell level is smaller than the pilot frequency start-up threshold according to the main service cell level information and the pilot frequency start-up threshold of each sampling point; determining a first ratio according to the number of sampling points and the total number of sampling points of which the level of the main service cell is less than the pilot frequency start measurement threshold, wherein the first ratio satisfies the following conditions:
where R1 is the first ratio, LT is the number of sampling points for which the primary serving cell level is less than the pilot frequency threshold, and S is the total number of sampling points.
Here, the total number of sampling points can be counted from each sampling point.
In actual life, each serving cell has its own inter-frequency threshold, the value of which is determined according to the actual scene, and the inter-frequency threshold determines whether the signal used by the terminal in the cell is to be switched to the signal of the neighboring cell. For example, the TD-LTE handover policy is the A1/A2+ A4 policy: when the level of the main service cell is less than the pilot frequency starting measurement threshold A2, reporting a pilot frequency switching measurement report, and when the level of the cell with configured neighboring cell relation in the report is greater than A4, initiating switching. If the primary serving cell level is greater than A1, the inter-frequency handover measurement report is cancelled. A4 means that the neighbor cell signal is good enough to reach a certain threshold, then if a fast handover is desired, the threshold is turned down, so that the neighbor cell signal is easily higher than the threshold, the terminal is easier to go to a4 to trigger the handover, and a2 is also turned up, that is, the cell is different to this extent, and it is easier to start measuring the inter-frequency neighbor cell.
Here, whenever the level of the main serving cell of the sampling point is smaller than the preset pilot frequency threshold of the main serving cell, the number of sampling points whose level of the main serving cell is smaller than the pilot frequency threshold is added up to 1, and in the initial state, the value is 0.
For example, suppose that there are eight sampling points A, B, C, D, E, F, G and H in the cell, their corresponding levels are-112 dbm, -78dbm, -89dbm, -125dbm, -96dbm, -68dbm, -60dbm and-72 dbm, respectively, and the inter-frequency threshold is-86 dbm. After the level of the main service cell is compared with the pilot frequency threshold one by one, the level of the main service cell of the A, C, D and E four sampling points is less than the pilot frequency threshold, so the number of the sampling points of which the level of the main service cell is less than the pilot frequency threshold is 4.
According to the first ratio
Wherein R1 is the first percentage, LT is the number of samples for which the primary serving cell level is less than the inter-frequency threshold, and S is the total number of samples. In combination with the above example, LT is 4, S is 8, then in this case,r1 is 50%.
And 103, adjusting the pilot frequency start-up threshold according to the first ratio.
Specifically, when the first ratio is greater than a preset first threshold, the pilot frequency start measurement threshold is adjusted.
Here, the first ratio is obtained through steps 101 and 102, and the preset first threshold to be compared with the first ratio has a certain value each time. Comparing the first occupation ratio with a preset first threshold, and when the first occupation ratio is smaller than or equal to the preset first threshold, indicating that the network quality of the measured cell is good at the moment, and reasonably setting the pilot frequency starting measurement threshold without adjustment; and when the first occupation ratio is larger than the preset first threshold, the network quality of the measured cell at the moment is poor, and the reason that the network quality of the cell is poor is that the measurement threshold of the pilot frequency is set unreasonably. Therefore, the background maintenance personnel can know whether the pilot frequency measurement threshold value of the cell needs to be adjusted or not through the comparison result. Preferably, the preset first threshold is 15% to 20%.
Specifically, the adjustment is that a background maintenance worker adjusts and modifies corresponding algorithm codes or parameter settings through a network management system.
It should be noted that steps 101 to 103 are a real-time continuous loop process, and the process is stopped until the inter-frequency threshold is not needed to be adjusted (the inter-frequency threshold has reached the target value), that is, the network quality of the measured cell is good (the first occupancy ratio is less than or equal to the preset first threshold).
Prior to step 103, the method further comprises:
and determining a second ratio of the weak coverage sampling points according to the level information of the main service cell of each sampling point.
Specifically, according to the level of the main service cell and a preset weak coverage level, the number of sampling points of which the level of the main service cell is smaller than the weak coverage level is determined; determining a second proportion according to the number of sampling points and the total number of sampling points of which the main service cell level is smaller than the weak coverage level, wherein the second proportion meets the following requirements:
where R2 is the second fraction, PC is the number of samples for which the primary serving cell level is less than the weak coverage level, and S is the total number of samples.
Here, the weak coverage means that the coverage area required by the base station is large, the base station spacing is too large, or the boundary area signal is weak due to building occlusion. The weak coverage is generally less than-90 dBm at the Received Signal Level (Rxlev). This phenomenon directly affects the call quality and requires great attention from operators.
The second ratio is obtained in a manner similar to that described in step 102 with respect to the first ratio, and will not be described in detail here.
When the first ratio is greater than a preset first threshold, before adjusting the pilot frequency start measurement threshold, the method further includes:
if the second ratio is less than or equal to a preset second threshold, judging whether the first ratio is greater than a preset first threshold;
and if the second ratio is larger than a preset second threshold, processing according to the weak coverage problem.
Here, the second ratio is used as a reverse control condition, so that a weak coverage phenomenon caused by untimely switching in the process of adjusting the threshold of the pilot frequency is avoided. The method ensures that the weak coverage problem is eliminated when the pilot frequency start detection threshold is adjusted, and improves the diagnosis efficiency and accuracy.
For the processing of the weak coverage problem, because the coverage field strength of the target cell is not enough, the signal strength cannot ensure normal conversation. The simplest solution is station-adding, and other solutions may include engineering parameters such as increasing power, adjusting antenna azimuth, etc.
Therefore, according to the first ratio, an unreasonable pilot frequency start-up threshold is found and adjusted, the limitation that the traditional analysis method is used for analyzing the phenomenon of low webpage downloading rate caused by unreasonable pilot frequency start-up threshold is overcome, the phenomenon of weak coverage caused by untimely adjustment and switching of the pilot frequency start-up threshold can be prevented, the webpage downloading rate is improved, and the user online experience is enhanced.
Example two
An embodiment of the present invention provides a threshold adjustment method, which is applied to a threshold adjustment device, and as shown in fig. 2, it is assumed that S is a target detection low-rate base station and R is a coverage cell of S, where the method includes:
The information of the low rate base station S required here can be obtained from the network management system.
In real life, the reason why the base station S generates a low rate relates to many aspects, such as: wireless side explicit causes such as coverage, capacity, bearer, etc. If the reason of the low rate is judged to be the dominant reason such as the wireless side, the low rate phenomenon is solved by processing by using the prior art means.
Generally, a complete networking scheme usually uses macro cells to complete large area coverage, micro cells to cover hot spots or blind areas, and meanwhile, rich wireless resources also enable Time Division-Synchronous Code Division Multiple access (TD-SCDMA) networking to use different networking such as omnidirectional or directional, single or Multiple carrier frequency, common or different frequency networking, and the like.
The fact that the R cell is in the pilot frequency networking mode is a precondition for judging whether the pilot frequency starting measurement threshold is reasonable or not.
The OMC-R is a unified management platform of the network elements of the radio access network and can acquire MR data of an R cell.
Here, the first and second ratios of the R cell can be calculated by combining the MR data acquired in step 204 and the specific method in the first embodiment.
And step 206, judging whether the second ratio of the R cell is greater than a preset second threshold. If yes, go to step 209; if not, go to step 207.
Before judging whether the first occupation ratio of the R cell is larger than a preset first threshold, judging whether the second occupation ratio of the R cell is larger than a preset second threshold, and effectively preventing the weak coverage phenomenon caused by untimely adjustment and switching of the pilot frequency start-up measurement threshold.
And step 208, adjusting the pilot frequency start-up measurement threshold of the R cell.
The adjustment is a dynamic continuous optimization process, i.e., steps 204 to 208 are a loop process. And stopping adjustment until the first occupation ratio is less than or equal to a preset first threshold, and terminating the circulation.
And step 209, performing fault and/or poor quality processing on the R cell according to the prior art.
For the fault and/or poor quality of the R cell caused by the dominant reasons, a background maintenance worker can know the specific reasons through a network management system, and can solve the low-rate problem through modification of background algorithm codes and/or on-site troubleshooting.
In daily low rate analysis, for example, to solve the problem of low rate distribution in thirteen-acre cells in shaoxing city, as shown in fig. 3, the cell adopts 38350 frequency points, the frequency points around the cell are 37900 macro station coverage, and the inter-frequency threshold a2 is-84 dbm. After the user reflects the low rate of the user webpage downloading in 7 months and 23 days, the analysis of other indexes is normal, after the positioning is carried out by the method, the A2 threshold is gradually optimized to-100 dbm through optimization, and the phenomenon of low rate of downloading is solved. The web page download rate is increased from 1681.82kbps before optimization to 2304.62 kbps.
