step S01, obtaining terminal probe information reported by all access points in a preset area of a preset time period, wherein the terminal probe information at least comprises an access point identifier and terminal uplink signal strength.

As shown in fig. 2, the WLAN and TD-LTE common antenna feeder room subsystem adopted in the embodiment of the present invention is a combination of a 4G network and a WLAN network, where a combiner is connected to a 4G network room website and a WLAN access point (WLAN-AP) respectively, and is connected to at least one antenna interface through the same feeder line, where the antenna interface includes a 4G radio frequency antenna and a WLAN radio frequency antenna, and is used to transmit and receive information with each terminal.

TABLE 1

The server may collect terminal probe information reported by all access points in a preset area, for example, in a building where a 4G indoor site and a WLAN network are integrated, in a preset period, for example, 1 day or half day.

Step S02, according to the access point identification, dividing all terminal probe information into probe information sets corresponding to each access point one by one; wherein, the access point identifiers of all terminal probe information in the same probe information set are the same.

And the server divides all terminal probe information into probe information sets corresponding to each access point one by one according to the access point identifiers contained in the probe information, namely, terminal probe information reported by the same access point is classified into the same probe information set. At this time, the access point identifiers of all terminal probe information in the same probe information set are the same.

Step S03, obtaining the weak coverage proportion of each access point according to a preset signal strength threshold; and the weak coverage proportion is a proportion occupied by terminal probe information of which the terminal uplink signal intensity is smaller than the signal intensity threshold value, wherein the weak coverage proportion is a probe information set corresponding to the access point.

In order to measure whether the weak coverage phenomenon of the 4G network exists, the relation between the received power of the transmitted reference signal of the terminal in the 4G network and the uplink signal strength of the terminal under the WLAN network can be obtained through calculation or measurement according to the design of the local network architecture in the early stage, and then the corresponding weak coverage standard under the WLAN network is obtained according to the standard for judging the weak coverage phenomenon of the 4G network, wherein the weak coverage standard at least comprises a signal strength threshold value, such as-90 dBm.

The terminal upstream signal strength of each terminal probe information in each set of probe information is then compared to the signal strength threshold. If the uplink signal intensity of the terminal is higher than the signal intensity threshold, the signal intensity reported by the corresponding probe meets the requirement; if the uplink signal strength of the terminal is smaller than the signal strength threshold, determining that the signal strength reported by the corresponding probe does not meet the requirement, and at the moment, marking the probe information of the terminal as weak coverage information. After all the comparisons are completed, the number of pieces of weak coverage information determined in the set of probe information is compared with the number of pieces of terminal probe information in the set of probe information, thereby obtaining a weak coverage ratio.

And step S04, if the weak coverage ratio of the access point is larger than a preset ratio threshold value, judging that the weak coverage exists in the area corresponding to the access point.

And comparing the calculated weak coverage ratio with a preset ratio threshold, wherein the ratio threshold can be obtained according to the standard of weak coverage phenomenon judgment of the 4G network, and can be the same as the weak coverage ratio threshold in the 4G network, for example, 90%.

If the weak coverage ratio is smaller than the ratio threshold, determining that the area covered by the corresponding access point is normal; if the weak coverage ratio is greater than the ratio threshold, it may be determined that weak coverage exists in the area covered by the corresponding access point.

According to the embodiment of the invention, through analyzing the uplink signal intensity of the terminal in the terminal probe information reported by the access point, according to the preset signal intensity threshold and the proportion threshold, whether the area where the terminal is located has the phenomenon of weak coverage of the 4G network can be more simply and conveniently judged.

Based on the above embodiment, further, before the step S02, the method further includes:

acquiring a linear relation between the reference signal receiving power of the 4G network in the area and the terminal uplink signal strength of the WLAN network;

and obtaining the signal strength threshold according to the linear relation and a preset reference signal receiving power threshold.

According to the embodiment of the invention, whether the 4G network in the same area has weak coverage phenomenon is judged according to the analysis of the uplink signal intensity of the terminal reported by the probe sent by each terminal under the WLAN network probe rule. For this purpose, a linear relationship between the uplink signal strength of the terminal and the reference signal received power used for determining the weak coverage phenomenon in the 4G network in the prior art needs to be obtained.

As the 4G room branch station mainly adopts E frequency bands 2320-2370MHz, the WLAN room branch combiner mainly adopts 802.11G to work at 2.4-2.4835GHz, the frequency bands of the two are very close, the difference of the frequency bands can be ignored in the specific calculation process, and the 2.4GHz loss table is referred.

According to the free space loss formula: flpl=32.44+ (20log 10 (F)) +20log10 (D), wherein FLPL is free space loss power, F is frequency, and D is distance. It is understood that, when the frequencies are the same, only the distance factor needs to be considered.

For this purpose, calculations are required based on the distance between the individual devices and terminals in the specific network architecture. In the network architecture of the embodiment of the invention:

in the 4G network, the formula of the reference signal received power RSRP is as follows:

RSRP＝P _STA-4G free space loss of the antenna interface to the terminal,

wherein the P is _STA-4G The 4G output power for the antenna interface may be-10 dBm to-12 dBm;

under WLAN network, terminal uplink signal strength WLAN _RSSI Formula (i) ofThe following steps:

WLAN _RSSI ＝P _STA-WLAN free space loss of PL-antenna interface to terminal,

wherein said P _STA-WLAN The transmit power for the terminal may be 17dbm and pl is the feeder loss of the antenna interface to the access point.

It follows that the linear relation between the terminal uplink signal strength and the reference signal received power is due to the feeder loss, i.e. WLAN _RSSI -RSRP＝P _STA-WLAN -PL-P _STA-4G . The feeder loss PL may be calculated according to the actual WLAN network construction situation, for example, if the maximum power of the access point is 27dBm, and the rated WLAN output power of the antenna interface is 12-15dBm, since the uplink and downlink feeder losses are the same, it is known that the feeder loss PL is 12-15dBm.

When pl=12 dBm, the RSRP is higher than WLAN _RSSI 15-17dBm smaller;

when pl=15 dBm, the RSRP is higher than WLAN _RSSI And is 12-14dBm smaller.

So when pl=12-15 dBm, the linear relation between the uplink signal strength of the terminal and the reference signal received power is that the RSRP is higher than the WLAN _RSSI And is 12-17dBm smaller.

At this time, the signal strength threshold of the corresponding uplink signal strength of the terminal can be obtained according to the limitation of the RSRP value in the standard of the weak coverage phenomenon judgment of the 4G network. For example, when the threshold range of the RSRP value is-105 dBm or less, it may be determined that the corresponding terminal may be in a weak coverage area, and the signal strength threshold may be about-90 dBm or less.

According to the embodiment of the invention, through analyzing the uplink signal intensity of the terminal in the terminal probe information reported by the access point, according to the preset signal intensity threshold and the proportion threshold, the signal intensity threshold can judge whether the area where the terminal is located has the weak coverage phenomenon of the 4G network or not more simply and conveniently through the linear relation between the uplink signal intensity of the terminal and the receiving power of the reference signal and the reference signal of the 4G network.

Based on the above embodiment, further, the terminal probe information further includes a terminal identifier and a reporting time, and correspondingly, the method further includes, before step S02:

deleting the terminal probe information which does not meet the preset periodic condition from all the terminal probe information reported by all the access points; wherein, the cycle condition is specifically:

and in a preset reporting period, if at least two pieces of terminal probe information exist in each terminal identifier, only one piece of terminal probe information with the highest uplink signal intensity of the terminal is reserved.

Since a terminal transmit probe report may be received by antenna interfaces under multiple access points at the same time, the server may receive multiple pieces of terminal probe information containing the same terminal identity but different access point identities at the same time or close to the same time. For easy and reasonable calculation, the server needs to identify and clean the terminal probe information.

The server may set a reporting period, for example, 10 seconds, for reporting the terminal probe information of the same terminal to each access point; or setting reporting period of reporting terminal probe information for each access point, wherein the terminal probe information of each terminal in each reporting period is only one, and the terminal probe information reported by the access point also comprises terminal identification of the terminal sending the corresponding probe report and reporting time when reporting the terminal probe information. After the server collects the terminal probe information reported by all the access points in the time period, according to the reporting time in the terminal probe information, if at least two pieces of terminal probe information containing the same terminal identifier exist in the same reporting period, the server can judge that the terminal probe information is respectively sourced from different access points. And comparing the terminal uplink signal intensities in the terminal probe information with the same terminal identification, reserving one piece of terminal probe information with the highest terminal uplink signal intensity, and deleting other terminal probe information.

Based on the above embodiment, further, before the step S03, the method further includes:

deleting terminal probe information which does not meet preset residence conditions from all terminal probe information reported by the access point; wherein, the resident condition specifically is:

and the number of the probe information of all terminals containing the same access point identifier and the same terminal identifier in a preset stable period is not less than a preset number threshold.

When the position of the terminal changes, the uplink signal strength of the terminal of the probe report sent by the terminal acquired by the access point also changes correspondingly, so that in order to accurately judge the coverage quality of the 4G network signal in the coverage area of the access point, the terminal position needs to be selected to be fixed in a preset stable period, that is, the time existing in the area corresponding to the access point is greater than or equal to the preset residence time, for example, 5 minutes, and the terminal probe information corresponding to the terminal is needed to be selected. And determining that the terminal with the time shorter than the residence time in the stable period is in a moving state, and deleting the corresponding terminal probe information.

According to the reporting period, the residence time can be converted into a number threshold value of terminal probe information corresponding to each terminal, for example, residence time is 5 minutes=300 seconds, and the corresponding number threshold value is 30. The dwell condition is thus set such that the number of all terminal probe information containing the same access point identity and the same terminal identity is not less than the number threshold in each stable period.

Of course, the residence condition may be that all terminal probe information including terminal identifiers received by the service is also available, that is, the number of all terminal probe information including the same terminal identifier in the stable period is not less than a preset number threshold. The specific number threshold may be set according to actual needs, and is not particularly limited herein.

deleting terminal probe information meeting preset non-hot spot conditions from all terminal probe information reported by the access point; wherein the non-hotspot condition is specifically:

and the uplink signal intensity of the terminal in all terminal probe information corresponding to the terminal identifier is lower than a preset hot spot intensity threshold value.

Because the detection range of the access point is larger, the resident terminals outside the corresponding area can be detected, but because the distances between the resident terminals and the access point are longer, the uplink signal strength of the terminals in the corresponding terminal probe information is lower, and the method has no practical reference value. In order to exclude terminals outside these areas, the server may set a non-hotspot condition, specifically, if the uplink signal strength of the terminal including all the terminal probe information of the same terminal identifier is lower than a preset hotspot strength threshold, for example, -75dBm, it may determine that the terminal is a resident terminal outside the area, so that all the terminal probe information corresponding to the terminal may be deleted.

Based on the above embodiment, further, the method further includes:

and acquiring engineering parameter information of each access point, wherein the engineering parameter information at least comprises the access point identification and the position information.

According to the condition of WLAN indoor planning construction, the distribution density of access points is far higher than that of 4G cells, the coverage area of each access point reaches a plurality of room levels of the same floor under the normal condition, the coverage area of a single 4G cell reaches a plurality of buildings, the positioning weak coverage area is about 50 meters in horizontal plane precision, and floors cannot be distinguished due to lower indoor three-dimensional precision. Therefore, the positioning precision of the user can be greatly improved by utilizing the position information of the access point, the plane precision can reach 20M, and the indoor three-dimensional precision can distinguish floors. Thereby enabling a more accurate positioning of the weak coverage area.

For this purpose, the server also needs to acquire engineering parameter information of each access point, where the engineering parameter information includes at least the access point identifier and the access point location information. The engineering parameter information may be set according to actual needs, for example, may include Build name, floor name, AP Coverage, AP MAC, AP LON, and AP LAT, which are specifically shown in the following table:

fields	Description of the invention
		Build name	Building name
Floor name	Floor name
		AP name	Name of AP
AP Coverage	Literally describing the coverage of an AP, e.g. room number
		AP MAC	MAC address of AP
AP LON	Longitude of AP
		AP LAT	Dimension of AP

TABLE 2

According to the embodiment of the invention, through analyzing the uplink signal intensity of the terminal in the terminal probe information reported by the access point, according to the preset signal intensity threshold and the proportion threshold, whether the area where the terminal is located has the phenomenon of weak coverage of the 4G network or not can be more simply and conveniently judged, and the positioning precision of the weak coverage area is improved.

In particular, the method comprises the steps of,

according to the WLAN probe technology, when the terminal enters the coverage area of the WLAN network, the terminal periodically and automatically sends probe reports to the surroundings, the antenna interface sends the probe reports to the WLAN access point connected through the combiner after receiving the probe reports, and the access point processes the received probe reports correspondingly to obtain terminal probe information, and sends the terminal probe information to the acquisition module 10 for summarizing. The terminal probe information includes at least an access point identification of the access point and a terminal uplink signal strength (Received Signal Strength Indicator, RSSI) at which the access point receives the probe report.

The acquiring module 10 may collect terminal probe information reported by all access points in a preset area within a preset time period, and send the terminal probe information to the grouping module 11.

The grouping module 11 divides all terminal probe information into probe information sets corresponding to each access point one by one according to the access point identifiers contained in the probe information, namely, terminal probe information reported by the same access point is classified into the same probe information set. At this time, the access point identifiers of all terminal probe information in the same probe information set are the same.

In order to measure whether the weak coverage phenomenon of the 4G network exists, the relation between the received power of the reference signal sent by the terminal in the 4G network and the uplink signal strength of the terminal under the WLAN network can be obtained through calculation or measurement according to the design of the local network architecture in the early stage, and then the corresponding weak coverage standard under the WLAN network is obtained according to the standard for judging the weak coverage phenomenon of the 4G network, wherein the weak coverage standard at least comprises a signal strength threshold value.

The calculation module 12 compares the terminal uplink signal strength of each terminal probe information in each probe information set obtained by the grouping module 11 with the signal strength threshold. If the uplink signal intensity of the terminal is higher than the signal intensity threshold, the signal intensity reported by the corresponding probe meets the requirement; if the uplink signal strength of the terminal is smaller than the signal strength threshold, determining that the signal strength reported by the corresponding probe does not meet the requirement, and at the moment, marking the probe information of the terminal as weak coverage information. After all the comparisons are completed, the number of the weak coverage information determined in the probe information set is compared with the number of all the terminal probe information in the probe information set, so that a weak coverage ratio is obtained and sent to the determining module 13.

The judging module 13 compares the received weak coverage ratio with a preset ratio threshold, where the ratio threshold may be obtained according to a criterion for judging a weak coverage phenomenon of the 4G network, and may be specifically the same as the weak coverage ratio threshold in the 4G network.

The device provided in the embodiment of the present invention is used for executing the above method, and the function of the device specifically refers to the above method embodiment, and the specific method flow is not repeated herein.

In particular, the method comprises the steps of,

according to the embodiment of the invention, whether the 4G network in the same area has weak coverage phenomenon is judged according to the analysis of the uplink signal intensity of the terminal reported by the probe sent by each terminal under the WLAN network probe rule. For this purpose, a linear relation between the uplink signal strength of the terminal and the reference signal received power used for judging the weak coverage phenomenon in the 4G network in the prior art needs to be obtained by a linear relation module.

According to the free space loss formula: flpl=32.44+ (20 log10 (F)) +20log10 (D), where FLPL is free space loss power, F is frequency, and D is distance. It is understood that, when the frequencies are the same, only the distance factor needs to be considered.

RSRP＝P _STA-4G free space loss of the antenna interface to the terminal,

under WLAN network, terminal uplink signal strength WLAN _RSSI The formula of (2) is as follows:

WLAN _RSSI ＝P _STA-WLAN free space loss of PL-antenna interface to terminal,

When pl=12 dBm, the RSRP is higher than WLAN _RSSI 15-17dBm smaller;

when pl=15 dBm, the RSRP is higher than WLAN _RSSI And is 12-14dBm smaller.

At this time, the threshold module may obtain a signal strength threshold of the corresponding uplink signal strength of the terminal according to the limitation of the RSRP value in the criterion of the weak coverage phenomenon judgment of the 4G network and the linear relationship obtained by the linear relationship module. For example, when the threshold range of the RSRP value is-105 dBm or less, it may be determined that the corresponding terminal may be in a weak coverage area, and the signal strength threshold may be about-90 dBm or less.
