Background technology
Wireless network coverage evaluating is the important process content in wireless network coverage planning and coverage optimization process, is the most groundwork ensureing wireless network performance.Wireless network coverage evaluating result can instruct coverage planning or the coverage optimization of wireless network exactly accurately, improve the performance of wireless network, otherwise, the wireless network coverage evaluating result that deviation is larger can cause coverage planning or coverage optimization result to expect to run counter to actual, can not reach the effect improving wireless network performance.
At present, TD-SCDMA wireless network coverage evaluating is carried out according to wireless network coverage rate, mainly contains the following two kinds method:
The first, adopt the method for road test, namely the user's calling on road measuring device simulated roadway is used, the wireless network relevant information corresponding to each measurement point is measured and records measurement result, judge the wireless network on each measurement point of road covers whether meet calling requirement, by calculating the coverage rate of wireless network on road (wireless network covers the ratio of the number meeting all measurement points in measurement point number and road that calling requires), thus the wireless network coverage condition on road is assessed.
The shortcoming of being carried out TD-SCDMA wireless network coverage evaluating by the method for road test is, because the method can not Middle Frequency for Simulated Surface Target (such as residential block, colleges and universities and shopping centre etc.) on user calling, therefore, road test method cannot determine the wireless network coverage rate on Area Objects, and in fact, a large amount of users is generation business on Area Objects, wireless network coverage rate on statistics Area Objects is very important, the wireless network coverage rate that therefore can only obtain for the road test method of special scenes (road) is unilateral, inaccurate, the wireless network assessment result obtained is caused also to be unilateral thus, inaccurate, wireless network coverage evaluating result according to utilizing road test method to obtain carries out wireless network coverage planning or coverage optimization, the requirement promoting wireless network performance can not be reached.
The second, adopt the method for emulation of coverage capability, multiple subregion is divided into by needing the region (network coverage assessment area) of carrying out wireless network coverage evaluating, level and the interference value of every sub regions in computing network coverage evaluating region is come according to network engineering parameter and propagation model, level and interference value are carried out contrasting the wireless network judged in this subregion and cover whether can meet call requirement, by calculating the coverage rate (wireless network cover the number of subregion and the ratio of network coverage assessment area whole subregion number that meet call requirement) of wireless network in network coverage assessment area, realize the assessment of wireless network at the coverage condition of network coverage assessment area.
As shown in Figure 1, adopt the method for emulation of coverage capability to carry out wireless network coverage evaluating specifically to comprise the following steps:
Step 101, by network coverage assessment area according to some scale, such as 5 meters * 5 meters, be divided into multiple grid (subregion), be convenient to follow-uply carry out wireless network covering analyzing to each grid.
Step 102, calculate the Primary Common Control Physical Channel field intensity (PCCPCH_RSCP of each grid, Primary Common Control Physical Channel Received Signal Code Power) and Primary Common Control Physical Channel Carrier interference ratio (PCCPCH_C/I, Primary Common Control Physical Channel Carrier-to-Interference ratio).
Step 103, the PCCPCH RSCP of each grid, PCCPCH C/I to be compared with set thresholding respectively, obtaining PCCPCH RSCP>RSCP_THRESHOLD (the PCCPCH_RSCP thresholding preset), and time the PCCPCH C/I>C/I_THRESHOLD of this grid (the PCCPCH_C/I thresholding preset), then determine that the wireless network in this grid covers satisfied call requirement, otherwise determine that the wireless network in this grid covers satisfied call requirement.
Step 104, basis " wireless network coverage rate=(wireless network covers all grid numbers of grid number/network coverage assessment area meeting call and require) * 100% " calculate wireless network coverage rate, assess according to the wireless network coverage condition of wireless network coverage rate to network coverage assessment area, wireless network coverage rate is higher, better to the wireless network coverage evaluating result of this network coverage assessment area.
The shortcoming using emulation of coverage capability method to carry out TD-SCDMA wireless network coverage evaluating is:
1, the precision for the parameter of carrying out wireless network coverage evaluating utilizing emulation of coverage capability method to obtain is lower, therefore, the wireless network coverage rate utilizing this parameter to determine is inaccurate, wireless network coverage evaluating result is also necessarily inaccurate, carry out wireless network coverage planning or coverage optimization according to this wireless network coverage evaluating result, the requirement promoting wireless network performance can not be reached.
2, do not take into full account business (user) distribution under different scene, in the coverage evaluating process of whole network coverage assessment area, do not have or the low traffic scene (this scene at least one grid marked off corresponding) of a small amount of user's communication, as the water surface, wetland etc. and the high traffic scene having more user's communication, as residential block, the coverage requirement of shopping centre etc. is identical with significance level, and in fact, under low traffic scene, because number of users and number of services are all fewer, the coverage requirement of wireless network obviously should lower than the coverage requirement of the wireless network under high traffic scene, namely wireless network covers the wireless network coverage requirement that preferentially meet high traffic scene, and whether low traffic scene is under wireless network covers due to no matter, all can not cause very large impact to user, also should lower than high traffic scene to the significance level of wireless network coverage evaluating to the significance level of wireless network coverage evaluating, namely the importance that the wireless network meeting high traffic scene covers is higher than the importance of the wireless network covering meeting low traffic scene.Determine in the process of wireless network coverage rate existing, by the wireless network coverage requirement of low traffic scene and high traffic scene be set to identical to the importance of wireless network coverage evaluating, by inaccurate for the wireless network coverage rate result making to determine, when causing later stage wireless network covering to carry out network coverage planning or coverage optimization work according to assessment result, the covering of high traffic scene be sacrificed in order to meet the covering of low traffic scene, the requirement promoting network performance can not be reached.
Wireless network coverage rate is as the basis of wireless network coverage evaluating, the decision accuracy of wireless network coverage rate is higher, the precision of the wireless network coverage evaluating result determined according to wireless network coverage rate is also higher, therefore, in order to improve the precision of wireless network coverage evaluating, be necessary very much to introduce a kind of scheme that can improve the decision accuracy of wireless network coverage rate.

At least one in described three kinds of modes can be used in the present invention program to improve the accuracy of the wireless network coverage rate determined.
Below in conjunction with Figure of description and each embodiment, technical solution of the present invention is described in detail.
Embodiment one,
The embodiment of the present invention one provides a kind of method determining wireless network coverage rate, and the steps flow chart of the method as shown in Figure 2, specifically comprises the following steps:
Step 201, determine measurement result and simulation value.
In this step, can for the network coverage assessment area being divided into several grids, obtain the measurement result of wireless network parameter corresponding to each measurement point utilizing road test method to obtain in advance, and obtain the simulation value of wireless network parameter corresponding to each grid of utilizing emulation of coverage capability method to obtain in advance.Concrete, measurement result and simulation value can respectively by carrying out road test and emulation of coverage capability operation is determined.
Described wireless network parameter can be PCCPCH_RSCP and PCCPCH_C/I.
Step 202, determine each grid falling to having measurement point.
In this step, the measurement point utilizing road test method to obtain can be divided in the grid belonging to this measurement point position, thus determine each grid falling to having measurement point, namely determine the grid be positioned on road.
The measurement point likely mistakenly certain being in A grid (being arranged on road) edge is in this step divided into the B grid (not being positioned on road) that reality does not comprise measurement point, the measurement result replacement reality causing follow-up mistake to be divided into the measurement point of B grid is not comprised the simulation value that the B grid of measurement point is corresponding, therefore, preferably, can determine in this step to fall to having measurement point, and the number of measurement point is greater than each grid of setting thresholding in this grid, the probability making the grid determined be positioned at road improves, thus reduce the measurement result that later use is positioned at the measurement point of road and replace the problem not being positioned at simulation value corresponding to the grid of road.
Step 203, for each wireless network parameter, obtain this wireless network parameter measurement result corresponding to measurement point.
After the measurement point obtained by road test carries out rasterizing process, the corresponding relation of grid and measurement point can be set up, and for each wireless network parameter corresponding to grid, this wireless network parameter measurement result of the measurement point corresponding with this grid can be determined.
The described measurement result that step 204, utilization obtain replaces the simulation value of this wireless network parameter corresponding to this grid.
In this step, the simulation value utilizing the described measurement result obtained in step 203 to replace this wireless network parameter corresponding to this grid can have multiple method, as, maximum measurement result in the described measurement result obtained is utilized to replace the simulation value of this wireless network parameter corresponding to this grid, minimum measurement result in the described measurement result obtained is utilized to replace the simulation value of this wireless network parameter corresponding to this grid, or a measurement result is to replace the simulation value etc. of this wireless network parameter corresponding to this grid to utilize additive method to determine from described measurement result, and preferably, in order to make the measurement result energy for replacing simulation value better, more fully reflect the attribute of this wireless network parameter that this grid is corresponding, the mean value of the described measurement result of acquisition can be utilized to replace the simulation value of this wireless network parameter corresponding to this grid.
Step 205, determine wireless network coverage rate.
In this step, the simulation value utilizing the wireless network parameter after being replaced and the simulation value of wireless network parameter be not replaced, determine the wireless network coverage rate of this network coverage assessment area.
Concrete, can according to the wireless network parameter threshold value for the unified setting of each grid, determine that the simulation value (after being replaced or be not replaced) of corresponding wireless network parameter is greater than the grid of setting threshold value, thus determine that wireless network covers the grid meeting coverage requirement, and utilize wireless network covering to meet the grid number of coverage requirement and the ratio of all grid numbers of network coverage assessment area, determine the wireless network coverage rate of this network coverage assessment area.
Step 201 ~ step 205, the lower wireless network parameter simulation value of a part of accuracy is replaced by the wireless network parameter measurement result utilizing accuracy higher, improve the accuracy of the wireless network coverage rate determined, simultaneously, the mean value of wireless network parameter measurement result can also be utilized further to replace wireless network parameter simulation value, make the measurement result for replacing simulation value better, more fully can reflect the attribute of the wireless network parameter that grid is corresponding, and reach the object of the accuracy improving the wireless network coverage rate determined further.
Except the method that the wireless network parameter higher in conjunction with precision determines wireless network coverage rate, can also pass through, for covering weight corresponding to each scene settings in wireless network coverage evaluating region, to reach the object improving the wireless network coverage rate accuracy determined further.
Step 205 specifically comprises:
Step 2051, the scene determining belonging to each grid.
Namely the scene determining belonging to grid determines the scene residing for grid.Scene can be understood as a slice communication zone defined according to geographical feature or other modes, and the definition mode of scene is different, then determine that the method for the scene belonging to each grid may be also different.In various embodiments of the present invention, for the scene defined for the various scenes in road and electronic chart are described.
In this step, the scene belonging to grid that simulation value can be replaced is defined as road, and can determine the scene belonging to each grid that simulation value is not replaced according to the scene information on electronic chart.
Determine the scene belonging to each grid that simulation value is not replaced according to the scene information on electronic chart, specifically comprise:
The position of this grid on electronic chart is determined according to the latitude and longitude information of grid, according to the scene information that electronic chart is arranged, if the position at this grid place covers a kind of scene, the scene that then this grid position covers is the scene belonging to this grid, otherwise, if the position at this grid place covers several scenes, then a kind of scene that in the scene covered by this grid, area is maximum is defined as the scene belonging to this grid.
When the scene that area is maximum in the scene that this grid covers is multiple, a kind of scene scene be defined as belonging to this grid that in the scene cover this grid, area is maximum can be, but not limited to by following two kinds of modes:
The first, select arbitrarily one as the scene belonging to this grid from multiple scenes that area is maximum.
The second, from the maximum multiple scenes of area, select the scene identical with (or multiple) grid that this grid is close to as the scene belonging to this grid.
Step 2052, determine the covering weight of grid.
Under grid is in certain scene, then this grid is identical with this scene to the importance of wireless network coverage evaluating, that is, the covering weight of grid is identical with the covering weight of the scene belonging to this grid.Therefore, according to the scene of setting and scene belonging to the corresponding relation of covering weight and grid, the covering weight that grid is corresponding can be determined.
Step 2053, determine whether the network coverage of grid meets coverage requirement.
When can all be greater than the threshold value of setting at each wireless network parameter simulation value that grid is corresponding, determine that the wireless network of this grid covers and meet coverage requirement, otherwise, determine that the wireless network of this grid covers and do not meet coverage requirement.
Step 2054, determine wireless network coverage rate.
The ratio utilizing wireless network to cover the covering weight sum meeting all grids in the covering weight sum of each grid of coverage requirement and network coverage assessment area determines the wireless network coverage rate of this network coverage assessment area.
Step 205 is being refined as step 2051 ~ 2054, determine on the basis of the network coverage in conjunction with covering weight, can also be further, according to the difference of wireless network coverage evaluating region Scene, for the threshold value of scene settings wireless network parameter, improve the wireless network coverage rate accuracy determined further.
Preferably, after step 2051, before step 2053, step 205 also comprises step 2052 ':
Step 2052 ', determine the threshold value that in grid, each wireless network parameter is corresponding respectively.
Under grid is in certain scene, then the requirement that covers wireless network of this grid is identical with this scene, that is, the threshold value of each wireless network parameter of the scene correspondence setting of the threshold value of each wireless network parameter that grid is corresponding belonging to this grid.Therefore, this step specifically comprises: scene belonging to the scene of setting and the corresponding relation of wireless network parameter threshold value and grid, determines the threshold value that in grid, each wireless network parameter is corresponding respectively.
Now, for each grid, when the wireless network parameter simulation value that this grid is corresponding is greater than wireless network parameter threshold value corresponding to this grid, determines that the wireless network of this grid covers and meet coverage requirement, otherwise, determine that the wireless network of this grid covers and do not meet coverage requirement.
This step 2052 ' is not limited to execution after step 2052, before step 2053 as shown in Figure 2, also can perform after step 2051, before step 2052.
In the scheme that embodiment one provides, also can be covering weight corresponding to each scene setting, but determine on the basis of the method for wireless network coverage rate at the wireless network parameter higher in conjunction with precision, according to the difference of wireless network coverage evaluating region Scene, for the threshold value of scene settings wireless network parameter, when determining wireless network coverage rate, scene belonging to grid, judge whether the wireless network parameter that grid is corresponding reaches threshold value corresponding to this grid to determine whether the wireless network covering in this grid meets the demands, and utilize wireless network covering to meet the grid number of coverage requirement and the ratio of all grid numbers of network coverage assessment area, determine the wireless network coverage rate of this network coverage assessment area, thus reach the object improving the wireless network coverage rate accuracy determined further.
Certainly, according to the difference of wireless network coverage evaluating region Scene, for the threshold value of scene settings wireless network parameter, thus the scene belonging to grid, judge whether the wireless network parameter that grid is corresponding reaches the threshold value of setting to determine whether the wireless network covering in this grid meets the demands, and determine that the method for wireless network coverage rate also can separately for improving the wireless network coverage rate accuracy determined.
By the scheme that the embodiment of the present invention one provides, not only can improve the accuracy of the wireless network coverage rate determined, the one-sidedness problem utilizing road test method determination wireless network coverage rate to exist can also be overcome, make the wireless network coverage rate determined more fully can reflect the wireless network coverage condition of network coverage assessment area, and by arranging different covering weights and the method for thresholding to the grid under different scene, the wireless network of network coverage assessment area covers demand to make the wireless network coverage rate determined to reflect.
Below by a concrete example, for determining that the wireless network parameter of wireless network coverage rate is PCCPCH_RSCP and PCCPCH_C/I, and utilize three kinds of modes improving wireless network coverage rate provided by the invention to be example simultaneously, the scheme of the embodiment of the present invention one is described in detail.
Embodiment two,
The embodiment of the present invention two provides a kind of method determining wireless network coverage rate, and the steps flow chart of the method as shown in Figure 3, specifically comprises the following steps:
PCCPCH_RSCP and PCCPCH_C/I that step 301, acquisition utilize road test method to obtain in advance, and PCCPCH_RSCP and PCCPCH_C/I utilizing emulation of coverage capability method to obtain in advance.

When obtaining PCCPCH_RSCP and PCCPCH_C/I utilizing emulation of coverage capability method to obtain in advance:
First, according to the precision of electronic chart, network coverage assessment area can be divided foursquare grid, e.g., the precision of electronic chart is 5 meters, then the smallest dimension that can obtain the grid divided is 5 meters * 5 meters.
Then, PCCPCH_RSCP and PCCPCH_C/I can be determined according to network engineering parameter and propagation model, concrete, can in conjunction with antenna model according to wireless network parameter corresponding to each grid of formulae discovery below:
Damage-human body loss-cable loss-shadow fading value worn by PCCPCH_RSCP=PCCPCH transmitting power+broadcast antenna gain+other gain-propagation loss-building.
PCCPCH_C/I=(the strongest PCCCPH_RSCP of this grid)/(this grid is with other community of frequency PCCPCH_RSCP sum).
Step 302, rasterizing process is carried out to the measurement point that road test method obtains.
When the measurement point obtained road test method carries out rasterizing process, the method dividing grid when carrying out the method determination simulation value utilizing emulation of coverage capability in the Methods and steps 301 of grid division is identical, and the grid obtained after making the grid that obtains after dividing and dividing when determining simulation value is identical.
Step 303, determine each grid falling to having measurement point.
Preferably, in this step, the number of measurement point in grid can be greater than the grid of 5 (set points) as the grid determined.
Step 304, the mean value of measurement result is utilized to replace simulation value corresponding to grid.
After determining the grid containing at least 5 measurement points, for each grid determined, the mean value of the measurement result of each measurement point in this grid can be utilized to replace simulation value corresponding to this grid, concrete, can by the mean value of following formula determination measurement result:
Wherein, PCCPCH

represent with PCCPCH_C/I (i) PCCPCH_RSCP and the PCCPCH_C/I measurement result that i-th measurement point dropped in described grid is corresponding respectively, k is the number of the measurement point dropped in described grid.
Step 305, the scene determining belonging to each grid.
The grid that the grid be replaced for simulation value and simulation value are not replaced, determines the scene belonging to each grid.Scene belonging to the grid be replaced by simulation value is defined as road, and determines the scene belonging to each grid that simulation value is not replaced according to the scene information on electronic chart.
The threshold value that in step 306, the covering weight determining grid and grid, each wireless network parameter is corresponding respectively.
Arranging the basic principle covering weight is: cover weight larger, show that the impact of this scene on wireless network coverage rate is larger, otherwise, then show that the impact of this scene on wireless network coverage rate is less.
The basic principle arranging threshold value is: threshold value is lower, show that the wireless network coverage requirement of this scene is lower, otherwise, then show that the wireless network coverage requirement of this scene is higher, concrete, PCCPCH_RSCP thresholding and PCCPCH_C/I thresholding can be set according to the telephone traffic of scene carrying.
Due in an embodiment, scene belonging to grid may be road, or be the scene defined in electronic chart, and the scene on general electronic chart comprises following 13 types: the water surface (Water), marine site (Sea), wetland (Wet_land), suburb open field (Suburban_Open_Area), city open field (Urban_Open_Area), greenery patches (Green_Land), forest (Forest), high building (High_Buildings), general common building thing (Ordinary_Regular_Buildings), parallel common building thing (Paralle_Reqular_Buildings), irregular heavy construction (Irregular_Large_Buildings), asymmetric buildings thing (Irregular_Buildings) and village, suburb (Suburban_Village), therefore, scene can be set up, the PCCPCH_RSCP thresholding that this scene (being in the grid in this scene) is corresponding, the relation of PCCPCH_C/I thresholding and covering weight is as shown in table 1.Corresponding relation shown in table 1 is not limited to set up in this step, also can set up before this step.
Table 1
According to the scene belonging to table 1 and grid, the covering weight of grid can be determined.As, can the scene belonging to grid be greenery patches, determine that the covering weight of grid is 1, the scene belonging to grid be village, suburb, determines that the covering weight of grid is 2.
According to the scene belonging to table 1 and grid, for PCCPCH_RSCP and PCCPCH_C/I, the PCCPCH_RSCP thresholding that grid is corresponding and PCCPCH_C/I thresholding can be determined respectively.As, can the scene belonging to grid be greenery patches, determine that the PCCPCH_RSCP thresholding that grid is corresponding and PCCPCH_C/I thresholding are respectively-90 and-3.
