Embodiment
The flow chart of the network coverage void handling method based on different systematic evaluation that Fig. 1 provides for the embodiment of the present invention one, as shown in Figure 1, the described method that the present embodiment provides can be performed by a processing unit, this processing unit is preferably integrated is arranged at that operator supervises its belonging network, in the management platform safeguarded, be such as arranged in operation maintenance center OMC.The method is applicable to the covering cavity compensation deals mechanism of any one network system, such as LTE network system, global system for mobile communications (Global SystemFor Mobile Communications, hereinafter referred to as GSM), Wideband-CDMA (Wide band CodeDivision Multiple Access, hereinafter referred to as WCDMA) network system, TD SDMA (Time Division-Synchronous Code Division Multiple Access, hereinafter referred to as TD-SCDMA) network system etc.
The described method that the present embodiment provides specifically comprises the steps:
Step 101, obtain at least one user terminal switches to the Target cell in second network system the first switching times from the current source cell first network system;
Step 102, judge whether described first switching times is more than or equal to the first predetermined threshold value, if be more than or equal to, then perform step 103, otherwise terminate;
Step 103, determine that described first network system exists network coverage cavity, and adjust the covering parameter of the antenna of the first base station, to adjust the network coverage of described first network system, described covering parameter comprises angle of declination and the azimuth of described antenna, and described first base station is the base station covering described current source cell.
The present embodiment proposes a kind of network coverage void handling method based on different systematic evaluation, be the network system of pending covering cavity process with LTE network system in the present embodiment, and be described to cdma network system from LTE network systematic evaluation for user terminal.
Suppose that certain user terminal is current in LTE network system Zhong Mou community, namely described current source cell, service is provided for it by this LTE network system, due to the mobility of user terminal, if this user terminal is moved to another community, namely described Target cell, if the signal quality of this LTE network system in this Target cell is very poor, simultaneously, another network system such as cdma network system has the good network coverage to this Target cell, now in order to ensure that the service of this user terminal is not interrupted, often there is different systematic evaluation, namely switch in the current source cell of this user terminal by LTE network system in the Target cell in cdma network system.
Above-mentionedly only to illustrate for the different systematic evaluation of a certain user terminal, be understandable that, for above-mentioned LTE network system, the covering power moving to this LTE network system when other multiple user terminals is poor, during each cell-of-origin that namely signal quality is poor, often all can there is different systematic evaluation.So, the operator network management platform being arranged in far-end can add up each user terminal of acquisition switches to the Target cell of cdma network system the first switching times from the cell-of-origin of this LTE network system.
And then, judge whether this first switching times is more than or equal to the first predetermined threshold value, if be more than or equal to, then illustrate that this LTE network system exists network coverage cavity.Now, the base station of adjustment current source cell, namely such as angle of declination and/or the azimuth etc. of the antenna of described first base station cover parameter, thus adjust the network coverage of this LTE network system, and the covering cavity of this LTE network system is compensated.That is, by adjusting the covering parameter of the first base station of cell-of-origin, expand the coverage of this LTE network system, its region that should cover during to ensure that this LTE network system can cover the network planning.
In the present embodiment, by current source cell in acquisition first network system to the switching times of the Target cell in second network system, i.e. different systematic evaluation number of times, if this switching times is greater than the first predetermined threshold value, show to exist in first network system to cover cavity, namely this first network system should cover but the place do not covered, now, by automatically adjusting the angle of declination of the first base station of current source cell in first network system, azimuth adjusts the coverage of this first network system, thus realize the auto-compensation that first network system covers cavity, without the need to manual intervention, while improve the treatment effeciency of network coverage cavity compensation, be conducive to improving Consumer's Experience.
The flow chart of the network coverage void handling method based on different systematic evaluation that Fig. 2 provides for the embodiment of the present invention two, as shown in Figure 2, on basis embodiment illustrated in fig. 1, the method for the present embodiment comprises:
Step 201, obtain at least one user terminal switches to the Target cell in second network system the first switching times from the current source cell first network system;
Step 202, judge whether described first switching times is more than or equal to the first predetermined threshold value, if be more than or equal to, then perform step 203, otherwise terminate;
Above-mentioned steps with embodiment illustrated in fig. 1 in corresponding step consistent, repeat no more.
Step 203, preset step-length according to first, the angle of declination of antenna of described first base station of stepping adjustment;
The performance index of described first base station before the described angle of declination of adjustment that step 204, basis obtain in advance, determine whether the described performance index of described first base station after adjusting described angle of declination are improved, if improve, then perform step 205, otherwise, perform step 207;
Step 205, obtain at least one user terminal switches to the described Target cell in described second network system the second switching times from the described current source cell described first network system;
Step 206, judge whether described second switching times is less than the second predetermined threshold value, and terminate the adjustment of the network coverage to described first network system when being less than described second predetermined threshold value;
In the present embodiment, covering after cavity as LTE network system exists according to described first switching times determination first network system, preset step-length according to first, the angle of declination of the antenna of described first base station of stepping adjustment.This first default step-length is such as 0.1 degree.Described stepping adjustment can be understood as presets by described first the adjustment carrying out the angle of declination of antenna in units of step-length at every turn, after adjustment first, need to carry out following performance index with judgement that is the second switching times, when meeting certain condition, adjustment again, judgement can also be carried out, will describe in detail below detailed process.
Such as, step-length is preset according to first, such as 0.1 degree, after adjusting the angle of declination of the antenna of described first base station first, according to the performance index of described first base station before the described angle of declination of the adjustment obtained in advance, determine whether the described performance index of described first base station after adjusting described angle of declination are improved.Wherein, described performance index comprise at least one index in following index: access success rate, cutting off rate and described switching times.That is judge whether the performance index adjusting this first base station, front and back make moderate progress, because these performance index can both reflect the covering power of first network system, therefore, if these performance index make moderate progress mean that the adjustment to the angle of declination of the first antenna for base station can expand the coverage of this first network system.When being improved, and then at least one user terminal obtained after adjustment angle of declination switches to the second switching times of the described Target cell in described second network system from the described current source cell described first network system, obtain manner in step 101 shown in this obtain manner and Fig. 1 is similar, no longer describes in detail.Judge whether this second switching times is less than the second predetermined threshold value afterwards, and terminate the adjustment of the network coverage to described first network system when being less than described second predetermined threshold value.Wherein, this second predetermined threshold value can be identical with the first predetermined threshold value, also can be less than the first predetermined threshold value.
In the present embodiment, when the angle of declination of the antenna of adjustment first base station makes the performance index of this first base station make moderate progress, determine whether stopping the adjustment to the network coverage of first network system by the judgement of the second switching times.Ideally, if only adjust an angle of declination, the second switching times after this adjustment can be made to be less than the second predetermined threshold value, so can to stop the adjustment of the network coverage to first network system.But generally, the first default step-length is generally smaller, and only the adjustment of an angle of declination generally not easily ensures that the second switching times is less than the second predetermined threshold value.Now, if the second switching times is not less than the second predetermined threshold value, so can also continue to preset in units of step-length by first, continue the angle of declination of the antenna of adjustment first base station, again after adjustment, carry out the first base station performance index more whether to improve and whether the second switching times again after adjustment is less than the judgement of the second predetermined threshold value, i.e. so-called stepping adjustment, until the number of times that the second switching times meets Rule of judgment or the adjustment angle of declination being less than the second predetermined threshold value has reached certain number of times regulation.
The signal strength information of step 207, the second base station obtained at least one neighbor cell of described Target cell and geographical location information;
Step 208, according to the signal strength information of described second base station of each neighbor cell at least one neighbor cell described and geographical location information, and the geographical location information of described first base station obtained in advance, determine azimuthal adjustment direction of the antenna of described first base station;
Step 209, preset step-length according to second, according to the azimuth of the antenna of described first base station of described adjustment direction stepping adjustment;
Step 210, described performance index according to described first base station before the described angle of declination of the described adjustment obtained in advance, determine whether the described performance index of described first base station after adjusting described azimuth are improved, if improve, then perform step 211, otherwise feeding back unsuccessful information;
Step 211, obtain at least one user terminal switches to the described Target cell in described second network system the 3rd switching times from the described current source cell described first network system;
Step 212, judge whether described 3rd switching times is less than described second predetermined threshold value, and terminate the adjustment of the network coverage to described first network system when being less than described second predetermined threshold value.
In the present embodiment, when presetting step-length according to first, when the angle of declination adjusting the antenna of the first base station not making the performance index of this first base station make moderate progress, step-length can also be preset according to second further, adjust the azimuth of the antenna of this first base station.What deserves to be explained is, also directly can preset step-length according to second to adjust the azimuth of the antenna of this first base station and do not carry out adjusting the step of angle of declination, namely an adjustment can be selected in angle of declination and azimuth, but preferably according to the mode in the present embodiment, when angle of declination adjustment does not make the first base station performance target improvement, then adjust azimuth.Why be first because the adjustment of angle of declination is simpler relative to azimuth for angle of declination adjustment, first can certainly adjust azimuth, only whether preferred.
Before adjusting the azimuth of the antenna in the first base station, be different from the adjustment to angle of declination, first azimuthal adjustment needs to determine azimuthal adjustment direction.Specifically, first signal strength information and the geographical location information of the second base station at least one neighbor cell of second network system Target cell as described in cdma network system is obtained, and then according to the signal strength information of the second base station of each neighbor cell and geographical location information, and the geographical location information of the first base station obtained in advance, determine azimuthal adjustment direction of the antenna of the first base station, step-length is preset afterwards, according to the azimuth of the antenna of described first base station of described adjustment direction stepping adjustment according to second.
Particularly, can according to the signal strength information of the second base station of each neighbor cell and geographical location information, and first geographical location information of base station, judge that the signal of anticlockwise each adjacent area of this first base station is strong, or the signal of clockwise each adjacent area is strong, the signal of the vicinity in which direction illustrates that by force the covering power of this this direction second network system is better for first network system, so the azimuth of the antenna of the first base station should adjust to the direction that the signal of vicinity is strong, to compensate the covering cavity of first network system.After determining azimuthal adjustment direction, preset step-length according to second, according to the azimuth of the antenna of described first base station of described adjustment direction stepping adjustment, the process of this adjustment and the adjustment process of angle of declination similar, repeat no more.
And then, preset after step-length adjusts as angle of declination by first, needing to carry out judgement that whether the first base station performance index improve and the second switching times, whether to be less than the judgement of the second predetermined threshold value the same, after often adjusting first power parallactic angle according to azimuth adjustment direction and the second default step-length, also the performance index of described first base station before according to the adjustment angle of declination obtained in advance are needed, determine whether the performance index of this first base station after adjusting azimuth are improved, and when improving, obtain at least one user terminal switches to the described Target cell in described second network system the 3rd switching times from the described current source cell described first network system, and then judge whether the 3rd switching times is less than described second predetermined threshold value, and the adjustment of the network coverage to first network system is terminated when being less than the second predetermined threshold value.It is similar that judgement after this process and angle of declination adjust and stepping adjust processing procedure, repeats no more.
In the present embodiment, automatically can identify to determine in first network system, whether to there is covering cavity by the judgement whether different systematic evaluation number of times being greater than to the first predetermined threshold value; Automatically stepping adjusts angle of declination, the azimuth of the first base station of current source cell in first network system, by whether the first base station performance index is made moderate progress after the adjustment and when improve, according to adjustment angle of declination, different systematic evaluation number of times behind azimuth to the adjustment whether stopping the coverage to first network system, thus realize the auto-compensation that first network system covers cavity, without the need to manual intervention, while improve the treatment effeciency of network coverage cavity compensation, be conducive to improving Consumer's Experience.
