In specific implementation, the edge data center platform classifies the collected terminals according to the supported network types, wherein the network types at least include a 2G network, a 3G network and a 4G network.
Specifically, the network types supported by the terminal are obtained according to the operating system type and the operating system version of the terminal, and the terminal is divided into two types according to the supported network type being a 2G network and/or a 3G network and the supported network type being a 4G network.
In the embodiment of the present invention, the network types supported by different operating system versions of different brand terminals with an operating system type of Android are as follows: android 1.5, Android 1.6, Android 2.0/2.1, Android 2.2, Android 2.3, Android 3.0/3.1/3.2, Android4.0, Android 4.1, iphoneios 1, ios 2, ios 3 and ios4 all support 2G and/or 3G networks; android 4.2/4.3, Android 4.4, Android 5.0/5.1, Android 6.0, Android 7.0, iphoneios 5, ios 6, ios 7 and ios 8 all support 4G networks.
In specific implementation, 2G and 3G network data can be collected through a Gb + Iupps interface, and 4G network data can be collected through S1-MME, S1-U, S6a and SGI interfaces.

In specific implementation, the network switching time includes switching time between the 4G network and the 2G network or the 3G network, and time for the 4G network to be switched to the 4G network again.
Specifically, for each terminal, the edge data center platform respectively collects a network switching level value and a network switching time of the terminal, and may calculate and obtain a distance between the edge data center sector and a neighbor edge data center sector thereof by using the following formula:
wherein, w i 、w j Respectively representing the edge data center sector to which the terminal belongs and the neighbor edge data center sector;
d(w i ,w j ) Indicating the edge data center sector w to which the terminal belongs i And its neighborhood edge data center sector w j The distance between them;

And S14, judging whether the network coverage of the terminal is normal according to the corresponding relationship between the network switching time and the network coverage condition of different types of terminals stored in advance. If the network coverage is not normal, step S15 is executed, and if the network coverage is normal, the flow ends.
In specific implementation, the edge data center platform prestores corresponding relations between network switching time and network coverage conditions of different types of terminals, wherein the network coverage conditions comprise two conditions of normal network coverage and abnormal network coverage, if the network switching time of the terminal is included in a network switching time range interval when the network coverage condition corresponding to the prestored network switching time of the type of terminal is normal, the network coverage of the terminal is judged to be normal, and the position of the terminal is not a wireless network weak coverage area; and if the network switching time of the terminal is contained in the network switching time range interval when the network coverage condition corresponding to the network switching time of the type terminal stored in advance is abnormal, judging that the network coverage of the terminal is abnormal.
In the embodiment of the invention, for a terminal which does not support FR (Fast Return), for example, a terminal with different brands, of which the operating systems and operating system versions are Android 4.2/4.3, Android 4.4, Android 5.0/5.1, iphoneios 5, ios 6 and ios 9.2.0 or below, 3G network bridging is required, that is, the terminal returns to the 3G network from the 2G network first and then reselects back to the 4G network from the 3G network, in this case, the time delay for reselecting the 4G network is large, the network switching time is about 20 seconds, and the terminal belongs to the normal network coverage condition, and if the network switching time is more than 30 seconds, the terminal belongs to the abnormal network coverage condition.
For a terminal supporting FR, if operating systems and operating system versions of terminals of different brands are Android 6.0, Android 7.0, iphoneios 7, ios 8, and ios9.3.4 or more, in this case, a 2G network does not need to configure 4G frequency point information, the terminal can directly fall back to the 4G network from the 2G network according to frequency band information held before CSFB (Circuit Switched Fallback), after the CSFB call is finished, without reading 2G system information, the network switching time is about 1 second, which belongs to a normal network coverage condition, and if the network switching time is greater than 10 seconds, the network coverage condition is abnormal.
And if the network coverage is normal, judging that the position of the terminal is not a weak coverage area of the wireless network, and ending the process.

If any is not met, step S16 is executed, and if both are met, the flow ends.
In specific implementation, the edge data center platform prestores normal level value range intervals of network switching of different types of terminals and normal range intervals of distances between an edge data center sector to which the type terminal belongs and a neighbor edge data center sector. For example, the range of the normal level value of the 4G network handover 4G network of the terminal iphoneios 7 is [60,90], the range of the normal level value of the 4G network handover 2G and/or 3G network is [75,90], the range of the normal range of the distance between the edge data center sector to which the terminal belongs and the neighbor edge data center sector thereof is [100,200] m, if at least one of the obtained network handover level value of the terminal, the distance between the edge data center sector to which the terminal belongs and the neighbor edge data center sector thereof does not fall into the corresponding range, whether the version of the operating system of the terminal is lower than the preset version is continuously judged, if the obtained network handover level value of the terminal and the distance between the edge data center sector to which the terminal belongs and the neighbor edge data center sector thereof all fall into the corresponding range, and judging that the position of the terminal is not the weak coverage area of the wireless network, and ending the process.
And S16, judging whether the operating system version of the terminal is lower than a preset version, executing the step S17 when the operating version of the terminal is determined to be lower than the preset version, and otherwise, executing the step S18.
In this step, if at least one of the obtained network switching level value of the terminal and the distance between the edge data center sector to which the terminal belongs and the neighbor edge data center sector does not fall within the corresponding range interval, the terminal is determined to be located in a position other than the weak coverage area of the wireless network due to the fact that the version of the operating system of the terminal is too low.
And S17, judging that the position of the terminal is not a weak coverage area of the wireless network.
And S18, judging the position of the terminal to be a weak coverage area of the wireless network.
In specific implementation, when it is determined that the version of the operating system of the terminal is not lower than the preset version, that is, if at least one of the obtained network switching level value of the terminal and the distance between the edge data center sector to which the terminal belongs and the neighbor edge data center sector does not fall within the corresponding range interval, it is not caused by the fact that the version of the operating system of the terminal is too low, and it is determined that the location of the terminal is a weak coverage area of the wireless network.
Preferably, the area of the wireless network weak coverage area is calculated according to the following formula:
wherein, w i 、w j Respectively representing an edge data center sector to which the terminal belongs and a neighbor edge data center sector thereof;
∫(w i ) The area of a weak coverage area of the wireless network at the position of the terminal is represented;

a denotes an edge data center sector w to which a terminal belongs i And its neighborhood edge data center sector w j Similar matching degree parameter values of the same number appear;
v denotes the network switching time of the terminal, v max Indicating the maximum network switching time of the terminal.
Specifically, the Number may be an IMEI (International Mobile Equipment Identity) or an IMSI (International Mobile Subscriber Identity), which is not limited in the embodiment of the present invention.
