Embodiment
Fig. 1 is the flow chart of network coverage detection method embodiment one of the present invention, and as shown in Figure 1, the present embodiment network coverage detection method can comprise:
Step S101 receives positional information and signal strength values that at least one sampled point in the base station range reports.
Particularly, the base station in the present embodiment can be the LTE base station, if the subscriber equipmenies such as mobile phone can receive the signal that the base station sends, and can send information to the base station, and then this subscriber equipment is in the coverage of this base station.At first choose sampled point in base station range, this sampled point can be the arbitrary subscriber equipment in the base station ranges such as mobile phone.After choosing sampled point, receive actively or passively positional information and signal strength values that sampled point reports.Wherein positional information can be the latitude and longitude coordinates value of this sampled point, and signal strength values can be the received signal strength value of sampled point under this base station.
Step S102 according to the positional information of sampled point, determines first distance of distance map on this base station and adjacent base station line direction between at least one sampled point and the base station.
Particularly, when the wireless signal covering is carried out to the zone of required covering in the base station, because antenna may be different in the gain of different directions, perhaps cause the base station not identical in the transmitting power of different directions owing to the environment of different directions is different, the signal strength values of the base station emission that subscriber equipment receives in different directions is not identical yet yet.Therefore, need the covering radius on calculation base station and the adjacent base station line direction, thereby could accurately draw according to the covering radius of two base station line directions the relation of two base station coverage area.For example, in the i coverage of base station, choose sampled point X, base station j is the adjacent base station of base station i, after then obtaining the positional information of sampled point X, at first the latitude and longitude coordinates value by sampled point X and base station i calculates the distance B between sampled point X and the base station i, then sampled point X is mapped on the line direction of base station i and adjacent base station j, calculates sampled point X in the mapping point on this line direction and the distance between the i of base station, with its first distance as sampled point X.
Step S103, according to this first distance, the signal strength values of sampled point and the margin signal intensity threshold of base station, determine this base station with adjacent base station line direction on covering radius.
Particularly, according to the relation that is directly proportional with signal strength values of distance, can be according to the first distance of the sampled point that calculates, the signal strength values of sampled point, and the margin signal intensity threshold of default base station calculate the base station with neighboring station line direction on covering radius.Wherein the margin signal intensity threshold can be rule of thumb to be worth defaultly, and the signal strength values that sampled point receives thinks then that greater than this margin signal intensity threshold this sampled point is in the coverage of base station.For example, first of sampled point X the distance is X
I, j, the signal strength values of sampled point X is RSRP
X, the margin signal intensity threshold of base station i is RSRP
i, then use formula
Calculate base station i with adjacent base station j line direction on covering radius di
, j
Present embodiment, by positional information and the signal strength values that obtains the sampled point in the base station range, calculate the base station with adjacent base station line direction on covering radius, can obtain accurately and efficiently the base station with adjacent base station line direction on covering radius, thereby use this covering radius to determine relation between two base station coverage area, improve the efficient to network coverage detection.

According to the cosine law, can calculate sampled point 22 and be θ with respect to the angle 25 of base station 21 and base station 23 line directions
X, i, j
If θ
X, i, jLess than or equal to θ
I, j, then this sampled point 22 selects sampled point 22 to carry out calculating to base station 21 covering radiuss for the available sampling point in the predetermined angle scope.If θ
X, i, jGreater than θ
I, j, then this sampled point 22 is unavailable sampled point outside the predetermined angle scope, does not use its covering radius to base station 21 to calculate.
Present embodiment, by the predetermined angle scope, for calculation base station selecting suitable sampled point with the calculating of adjacent base station line direction covering radius, can reduce the amount of calculation when the calculation base station covering radius, and improve computational accuracy, thereby improve the efficient of calculating.
Further, there are several base stations in the network, before the base station is calculated with respect to the covering radius of adjacent base station, need at first to determine whether between the base station be adjacent base station.Can judge whether the distance between the base station determines between the base station whether be the neighboring station relation less than predeterminable range threshold value between default station.Between this station the predeterminable range threshold value can be rule of thumb be worth default.Particularly, the predeterminable range threshold value is D between default station
M, the latitude and longitude coordinates value of establishing base station i is (α
i, β
