Description
The present patent application is to be dividing an application of on 04 21st, 2011, application number are 201110100504.7, denomination of invention is " determining the method and apparatus of wireless network coverage rate " patent application the applying date.
Technical field
The present invention relates to moving communicating field, relate in particular to a kind of method and apparatus of definite wireless network coverage rate.
Background technology
Wireless network coverage evaluating is the important process content in wireless network coverage planning and coverage optimization process, is the groundwork that guarantees 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 be runed counter to actual expectation, can not reach the effect that improves wireless network performance.
At present, TD-SCDMA wireless network coverage evaluating is carried out according to wireless network coverage rate, mainly contains following two kinds of methods:
The method of the first, employing road test, use the user on road measuring device simulated roadway to call out, measurement result is measured and recorded to the wireless network relevant information that each measurement point is corresponding, whether the wireless network of judgement on each measurement point of road covers to meet calls out requirement, by calculating the coverage rate (measurement point number that wireless network covering satisfied calling require and road on the ratio of the number of all measurement points) of wireless network on road, thereby the wireless network coverage condition on road is assessed.
The shortcoming of carrying out TD-SCDMA wireless network coverage evaluating by the method for road test is, due to the method can not Middle Frequency for Simulated Surface Target (residential block for example, colleges and universities and shopping centre etc.) on user call out, therefore, road test method cannot be determined 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, it is also unilateral causing thus the wireless network assessment result obtaining, inaccurate, according to the wireless network coverage evaluating result of utilizing road test method to obtain, carry out wireless network coverage planning or coverage optimization, can not reach the requirement that promotes wireless network performance.
The second, adopt the method for emulation of coverage capability, the region (network coverage assessment area) that need to carry out wireless network coverage evaluating is divided into a plurality of subregions, according to network engineering parameter and propagation model, come level and the interference value of every sub regions in computing network coverage evaluating region, level and interference value are carried out recently judging the wireless network in this subregion covers whether can meet call requirement, by calculating wireless network in the coverage rate (wireless network covers and meets the number of subregion and the ratio of the whole subregion numbers of network coverage assessment area that call requires) of network coverage assessment area, realization is the assessment at the coverage condition of network coverage assessment area to wireless network.
As shown in Figure 1, adopting the method for emulation of coverage capability to carry out wireless network coverage evaluating specifically comprises the following steps:
Step 101, by network coverage assessment area according to some scale, for example 5 meters * 5 meters, be divided into a plurality of grids (subregion), be convenient to follow-up each grid be carried out to wireless network covering analyzing.
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) with 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 are compared with set thresholding respectively, obtaining PCCPCH RSCP>RSCP_THRESHOLD (predefined PCCPCH_RSCP thresholding), and during the PCCPCH C/I>C/I_THRESHOLD of this grid (predefined PCCPCH_C/I thresholding), determine that the wireless network covering in this grid meets call requirement, otherwise determine that the wireless network in this grid covers dissatisfied call requirement.
Step 104, basis " wireless network coverage rate=(wireless network covers and meets all grid numbers of grid number/network coverage assessment area that call requires) * 100% " calculate wireless network coverage rate, according to wireless network coverage rate, the wireless network coverage condition of network coverage assessment area is assessed, wireless network coverage rate is higher, just better to the wireless network coverage evaluating result of this network coverage assessment area.
The shortcoming of using emulation of coverage capability method to carry out TD-SCDMA wireless network coverage evaluating is:
That 1, utilizes that emulation of coverage capability method obtains is lower for carrying out the precision of parameter of wireless network coverage evaluating, therefore, it is inaccurate utilizing the wireless network coverage rate that this parameter is determined, wireless network coverage evaluating result must be also inaccurate, according to this wireless network coverage evaluating result, carry out wireless network coverage planning or coverage optimization, can not reach the requirement that promotes wireless network performance.
2, do not take into full account the distribution of business (user) under different scenes, in the coverage evaluating process of whole network coverage assessment area, do not have or the low traffic scene (corresponding at least one grid marking off of this scene) of a small amount of user's communication, as the water surface, wetland etc. and the high traffic scene that has 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, due to number of users and number of services all fewer, the coverage requirement of wireless network obviously should be lower than the coverage requirement of the wireless network under high traffic scene, be that wireless network covers the wireless network coverage requirement that preferentially meet high traffic scene, and due to no matter, whether low traffic scene is under wireless network covers, can not cause very large impact to user, to the significance level of wireless network coverage evaluating also should be lower than high traffic scene the significance level to wireless network coverage evaluating, the importance that meets the wireless network covering of high traffic scene will be higher than the importance that meets the wireless network covering of low traffic scene.In the process of existing definite wireless network coverage rate, the wireless network coverage requirement of low traffic scene and high traffic scene and be set to identical to the importance of wireless network coverage evaluating, the wireless network coverage rate result that makes to determine is inaccurate, cause later stage wireless network to cover while carrying out network coverage planning or coverage optimization work according to assessment result, can in order to meet the covering of low traffic scene, sacrifice the covering of high traffic scene, can not reach the requirement that promotes network performance.
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 of determining 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.

The third, according to the wireless network coverage requirement of scene, the wireless network parameter corresponding for this scene arranges threshold value, as for the equal fewer scene of number of users and number of services, the requirement that this scene covers wireless network is lower, can be the lower threshold value of wireless network parameter setting corresponding to this scene, and be all many higher threshold value of wireless network parameter setting corresponding to scene of number of users and number of services, follow-up when definite wireless network coverage rate, according to the scene under grid, judge that threshold value that whether wireless network parameter that grid is corresponding reaches setting determines that wireless network in this grid covers and whether meet the demands, thereby whether the wireless network that can judge for the demand of different scenes (grid) (in this grid) under this scene covers and meets the demands, reach the object that improves the wireless network coverage rate accuracy of determining.
In the present invention program, can improve the accuracy of the wireless network coverage rate of determining by least one in described three kinds of modes.
Below in conjunction with Figure of description and each embodiment, technical solution of the present invention is elaborated.
Embodiment mono-,
The embodiment of the present invention one provides a kind of method of definite 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 be for the network coverage assessment area that is divided into several grids, obtain the measurement result of the wireless network parameter that each measurement point utilize in advance road test method to obtain is corresponding, and the simulation value that obtains the wireless network parameter that each grid of utilizing in advance emulation of coverage capability method to obtain is corresponding.Concrete, measurement result and simulation value can be 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 that falls to having measurement point.
In this step, the measurement point that utilizes road test method to obtain can be divided in the grid under this measurement point position, thereby determine each grid that falls to having measurement point, determine and be positioned at the grid on road.
Likely by certain, the measurement point in A grid (being arranged on road) edge is divided into the B grid (not being positioned on road) that reality does not comprise measurement point mistakenly in this step, follow-up simulation value corresponding to B grid that does not comprise measurement point by the wrong measurement result replacement reality that is divided into the measurement point of B grid will be caused, therefore, preferably, can determine in this step and fall to having measurement point, and in this grid, the number of measurement point is greater than each grid of setting thresholding, the probability that the grid that makes to determine is positioned at road improves, thereby reduce measurement result that later use is positioned at the measurement point of road and replace the problem that is not positioned at the simulation value that the grid of road is corresponding.
Step 203, for each wireless network parameter, obtain this wireless network parameter measurement result corresponding to measurement point.
The measurement point that road test is obtained carries out, after rasterizing processing, can setting up the corresponding relation of grid and measurement point, and can, for each wireless network parameter corresponding to grid, determine this wireless network parameter measurement result of the measurement point corresponding with this grid.
The described measurement result that step 204, utilization obtain is replaced the simulation value of this wireless network parameter that this grid is corresponding.
In this step, the simulation value that utilizes the described measurement result obtaining in step 203 to replace this wireless network parameter that this grid is corresponding can have several different methods, as, utilize measurement result maximum in the described measurement result obtaining to replace the simulation value of this wireless network parameter that this grid is corresponding, utilize measurement result minimum in the described measurement result obtaining to replace the simulation value of this wireless network parameter that this grid is corresponding, or utilize additive method from described measurement result, to determine a measurement result and replace simulation value of this wireless network parameter that this grid is corresponding etc., and preferably, for making can be better for replacing the measurement result of simulation value, the attribute that more fully reflects this wireless network parameter that this grid is corresponding, can utilize the mean value of the described measurement result of acquisition to replace the simulation value of this wireless network parameter that this grid is corresponding.
Step 205, determine wireless network coverage rate.
In this step, utilize the simulation value of the wireless network parameter after being replaced and the simulation value of the wireless network parameter that is not replaced, determine the wireless network coverage rate of this network coverage assessment area.
Concrete, can be according to being the unified wireless network parameter threshold value of setting of each grid, the simulation value (after being replaced or be not replaced) of determining corresponding wireless network parameter is greater than the grid of setting threshold value, thereby determine that wireless network covers the grid that meets coverage requirement, and utilize wireless network to cover to meet the ratio of grid number and all grid numbers of network coverage assessment area of coverage requirement, determine the wireless network coverage rate of this network coverage assessment area.
Step 201～step 205, by utilizing the wireless network parameter measurement result that accuracy is higher, replace the wireless network parameter simulation value that a part of accuracy is lower, improved the accuracy of the wireless network coverage rate of determining, simultaneously, can also further utilize the mean value of wireless network parameter measurement result to replace wireless network parameter simulation value, make can better, more fully reflect the attribute of the wireless network parameter that grid is corresponding for replacing the measurement result of simulation value, and reach the object of the accuracy of the wireless network coverage rate that further raising determines.
Except determining the method for wireless network coverage rate in conjunction with the higher wireless network parameter of precision, can also be by setting corresponding covering weight for each scene in wireless network coverage evaluating region, reach the object of the wireless network coverage rate accuracy that further raising determines.
Step 205 specifically comprises:
Step 2051, determine the scene under each grid.
Determine the i.e. definite residing scene of grid of the affiliated scene of grid.Scene can be understood as a slice communication zone defining according to geographical feature or other modes, and the definition mode of scene is different, determines that the method for the scene under each grid may be also different.In various embodiments of the present invention, the scene that the defines various scenes in road and electronic chart of take describe as example.
In this step, the scene under the grid that simulation value can be replaced is defined as road, and can determine the scene under each grid that simulation value is not replaced according to the scene information on electronic chart.
According to the scene information on electronic chart, determine the scene under each grid that simulation value is not replaced, specifically comprise:
According to the latitude and longitude information of grid, determine the position of this grid on electronic chart, according to the scene information arranging on electronic chart, if the position at this grid place covers a kind of scene, the scene that this grid position covers is the scene under this grid, otherwise, if the position at this grid place covers several scenes, in the scene this grid being covered, a kind of scene of area maximum is defined as the scene under this grid.
When in the scene covering at this grid, the scene of area maximum is a plurality of, the scene that in the scene that this grid is covered, a kind of scene of area maximum is defined as under this grid can be, but not limited to by following two kinds of modes:
The first, from a plurality of scenes of area maximum, select arbitrarily one as the scene under this grid.
The second, from a plurality of scenes of area maximum, select scene that (or a plurality of) grid being close to this grid is identical as the scene under this grid.
Step 2052, determine the covering weight of grid.
Grid is under certain scene, and this grid is identical with this scene to the importance of wireless network coverage evaluating, that is, the covering weight of the scene that the covering weight of grid is affiliated with this grid is identical.Therefore,, according to scene under the corresponding relation of the scene of setting and covering weight and grid, can determine the covering weight that grid is corresponding.
Step 2053, determine whether the network coverage of grid meets coverage requirement.
Can when being all greater than the threshold value of setting, each wireless network parameter simulation value corresponding to grid determine that the wireless network covering of this grid meets coverage requirement, otherwise, determine that the wireless network covering of this grid does not meet coverage requirement.
Step 2054, determine wireless network coverage rate.
Utilize wireless network to cover to meet the ratio of the covering weight sum of all grids in the covering weight sum of each grid of coverage requirement and network coverage assessment area to determine the wireless network coverage rate of this network coverage assessment area.
Step 205 is being refined as to step 2051～2054, in conjunction with covering weight, determine on the basis of the network coverage, can also be further, according to the difference of wireless network coverage evaluating region Scene, for the threshold value of scene setting wireless network parameter, further improve the wireless network coverage rate accuracy of determining.
Preferably, after step 2051, before step 2053, step 205 also comprises step 2052 ':
Step 2052 ', determine in grid each wireless network parameter corresponding threshold value respectively.
Grid is under certain scene, and the requirement that this grid covers wireless network is identical with this scene, that is, the threshold value of each wireless network parameter that grid is corresponding is the threshold value of corresponding each wireless network parameter set of scene under this grid.Therefore, this step specifically comprises: according to scene under the corresponding relation of the scene of setting and wireless network parameter threshold value and grid, determine threshold value corresponding to each wireless network parameter difference in grid.
Now, for each grid, when wireless network parameter simulation value corresponding to this grid is greater than wireless network parameter threshold value corresponding to this grid, the wireless network of determining this grid covers and meets coverage requirement, otherwise, determine that the wireless network covering of this grid does not meet coverage requirement.
This step 2052 ' is not limited to carrying out after step 2052, before step 2053 as shown in Figure 2, also can be after step 2051, carry out before step 2052.
In the scheme that embodiment mono-provides, also can be covering weight corresponding to each scene setting, but at the wireless network parameter higher in conjunction with precision, determine on the basis of method of wireless network coverage rate, according to the difference of wireless network coverage evaluating region Scene, threshold value for scene setting wireless network parameter, when definite wireless network coverage rate, according to the scene under grid, judge whether wireless network parameter that grid is corresponding reaches threshold value that this grid is corresponding and determine that wireless network in this grid covers and whether meet the demands, and utilize wireless network to cover the ratio of the grid number and all grid numbers of network coverage assessment area that meet coverage requirement, determine the wireless network coverage rate of this network coverage assessment area, thereby reach the object of the wireless network coverage rate accuracy that further raising determines.
Certainly, according to the difference of wireless network coverage evaluating region Scene, threshold value for scene setting wireless network parameter, thereby according to the scene under grid, judge that threshold value that whether wireless network parameter that grid is corresponding reaches setting determines that wireless network in this grid covers and whether meet the demands, and the method for definite wireless network coverage rate also can be separately for improving the wireless network coverage rate accuracy of determining.
The scheme providing by the embodiment of the present invention one, not only can improve the accuracy of the wireless network coverage rate of determining, can also overcome and utilize road test method to determine the one-sidedness problem that wireless network coverage rate exists, the wireless network coverage rate that makes to determine can more fully reflect the wireless network coverage condition of network coverage assessment area, and by different covering weights and the method for thresholding being set to the grid under different scenes, make the wireless network coverage rate of determining can better reflect that the wireless network of network coverage assessment area covers demand.
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 that improve wireless network coverage rate provided by the invention is example simultaneously, and the scheme of the embodiment of the present invention one is elaborated.
Embodiment bis-,
The embodiment of the present invention two provides a kind of method of definite 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 the PCCPCH_RSCP and the PCCPCH_C/I that utilize in advance emulation of coverage capability method to obtain.
Obtain PCCPCH_RSCP and the PCCPCH_C/I utilize in advance road test method to obtain, can use the user on road measuring device simulated roadway to call out, and to PCCPCH_RSCP corresponding to each measurement point with PCCPCH_C/I measures and record.
Obtaining while utilizing in advance PCCPCH_RSCP that emulation of coverage capability method obtains and PCCPCH_C/I:
First, can network coverage assessment area be divided to foursquare grid according to the precision of electronic chart, as, the precision of electronic chart is 5 meters, the smallest dimension that can obtain the grid of division is 5 meters * 5 meters.
Then, can determine PCCPCH_RSCP and PCCPCH_C/I according to network engineering parameter and propagation model, concrete, can according to formula below, calculate the wireless network parameter that each grid is corresponding in conjunction with antenna model:
PCCPCH_RSCP=PCCPCH transmitting power+broadcast antenna gain+other gain-propagation loss-building is worn damage-human body loss-cable loss-shadow fading value.
PCCPCH_C/I=(the strongest PCCCPH_RSCP of this grid)/(this grid is with other community of frequency PCCPCH_RSCP sum).
Step 302, the measurement point that road test method is obtained carry out rasterizing processing.
When the measurement point that road test method is obtained carries out rasterizing processing, the method of carrying out dividing when the method for grid division is determined simulation value with the method for utilizing emulation of coverage capability in step 301 grid is identical, and the grid obtaining after division while making the grid that obtains after dividing with definite simulation value is identical.
Step 303, determine each grid that falls to having measurement point.
Preferably, in this step, the grid that the number of measurement point in grid can be greater than to 5 (set points) is as the grid of determining.
Step 304, utilize the mean value of measurement result to replace simulation value corresponding to grid.
After determining the grid that contains at least 5 measurement points, for each grid of determining, can utilize the mean value of the measurement result of each measurement point in this grid to replace the simulation value that this grid is corresponding, concrete, can determine by following formula the mean value of measurement result:
Wherein, PCCPCH
rSCPand PCCPCH
c/Irepresent respectively to drop on PCCPCH_RSCP that each measurement point in certain grid is corresponding and the mean value of PCCPCH_C/I measurement result, PCCPCH_RSCP (i) and PCCPCH_C/I (i) represent respectively to drop on corresponding PCCPCH_RSCP and the PCCPCH_C/I measurement result of i measurement point in described grid, and k is the number that drops on the measurement point in described grid.
Step 305, determine the scene under each grid.
The grid that the grid being replaced for simulation value and simulation value are not replaced, determines the scene that each grid is affiliated.Scene under the grid that simulation value is replaced is defined as road, and determines the scene under each grid that simulation value is not replaced according to the scene information on electronic chart.
Threshold value corresponding to each wireless network parameter difference in step 306, the covering weight of determining grid and grid.
The basic principle that covering weight is set is: covers weight larger, shows that this scene is larger on the impact of wireless network coverage rate, otherwise, show that this scene is less on the impact of wireless network coverage rate.
The basic principle that threshold value is set is: threshold value is lower, the wireless network coverage requirement that shows this scene is lower, otherwise, show that the wireless network coverage requirement of this scene is higher, concrete, can PCCPCH_RSCP thresholding and PCCPCH_C/I thresholding be set according to the telephone traffic of scene carrying.
Due in an embodiment, scene under grid may be road, or be the scene defining in electronic chart, and 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), irregular building (Irregular_Buildings) and village, suburb (Suburban_Village), therefore, can set up scene, the PCCPCH_RSCP thresholding that this scene (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 before this step, set up.
Table 1
According to the scene under table 1 and grid, can determine the covering weight of grid.As, can be greenery patches according to the scene under grid, the covering weight of determining grid is 1, according to the scene under grid, is village, suburb, the covering weight of determining grid is 2.
According to the scene under table 1 and grid, for PCCPCH_RSCP and PCCPCH_C/I, can determine respectively PCCPCH_RSCP thresholding and PCCPCH_C/I thresholding that grid is corresponding.As, can be greenery patches according to the scene under grid, determine that PCCPCH_RSCP thresholding and PCCPCH_C/I thresholding that grid is corresponding are respectively-90 and-3.
