h₁＝44330*(1-(P₁/1013.25)^0.19) (3)

h₂＝44330*(1-(P₂/1013.25)^0.19) (4)

In another example, the other terminal may calculate the terminal height information according to the barometric pressure-altitude conversion formula (as in the above formula 1) and the measured barometric pressure value.

Optionally, when the other terminal further determines the latitude and longitude information of the terminal, the other terminal determines the latitude and longitude information of the terminal, including: and acquiring the current longitude and latitude information of the terminal through the installed GPS assembly.

Of course, other terminals may determine the latitude and longitude information in other manners, such as: positioning through a mobile base station; assisted Global Positioning System (AGPS), etc., which are not limited in this embodiment.

Alternatively, step 703 may be performed after step 702; alternatively, it may be performed before step 702; alternatively, it may also be performed simultaneously with step 702.

In step 704, the other terminal sends the second network identifier and the terminal altitude information to the server.

Step 705, the server receives the second network identifier and the terminal height information sent by at least one other terminal.

Optionally, the server receives a network fingerprint and the terminal altitude information, the network fingerprint including the second network identification. The terminal height information is calculated by other terminals according to the measured air pressure value.

Optionally, the server may also receive latitude and longitude information of the terminal sent by other terminals.

Optionally, the server structurally stores the second network identification and the terminal altitude information. Schematically, the correspondence between the second network identification and the terminal height information shown in fig. 8 is referred to.

Step 706, the server determines the network height information corresponding to each second network identifier according to the m pieces of terminal height information.

Optionally, after receiving the terminal height information, the server further calculates network positioning information corresponding to each second network identifier according to the terminal height information of at least one other terminal; and storing the corresponding relationship between the second network identification and the network positioning information.

Illustratively, the server obtains m pieces of terminal height information corresponding to each second network identifier from the second network identifiers and the terminal height information sent by at least one other terminal; and determining network height information corresponding to each second network identifier according to the m pieces of terminal height information, wherein m is a positive integer. At this time, referring to fig. 9, for m pieces of terminal height information corresponding to each second network identifier, the server determining the network positioning information according to the m pieces of terminal positioning information includes the following steps:

Of course, the server may also determine the data extraction interval in other manners, such as: determining the minimum value as the lower limit value of the data extraction interval, and taking the maximum value as the upper limit value of the data extraction interval to obtain the data extraction interval; the present embodiment does not limit the manner in which the server determines the data extraction interval.

And step 93, extracting n interval data from the data extraction interval, wherein n is an integer greater than 1.

Optionally, the server extracts n interval data in the data extraction interval, including: in the data extraction interval, taking the lower limit value of the data extraction interval as first interval data; then, extracting interval data every other preset numerical value to obtain n interval data. The preset value can be set in the server for the developer; or, the server randomly selects the server, which is not limited in this embodiment.

Such as: if the data extraction interval of the terminal height information is [100m, 150m ] and the preset value is 1m, the server takes the lower limit value 100 of the data extraction interval as the first interval data, and then extracts one interval data every 1m, so that the server can obtain 51 interval data.

And step 94, calculating the occurrence probability corresponding to each interval data in the n interval data.

Optionally, the server calculates an occurrence probability corresponding to each interval data, including: for the ith interval data, counting the number of the terminal positioning information corresponding to the network fingerprint in a subinterval formed by the (i-1) th interval data and the ith interval data; and dividing the number by the total number of the terminal positioning information corresponding to the network fingerprint to obtain the occurrence probability corresponding to the interval data.

In summary, according to the method for positioning a terminal provided in this embodiment, when determining the terminal height information by another terminal, the terminal height information is determined by combining the standard height of the weather monitoring station, the reference barometric pressure value issued by the weather monitoring station, and the measured barometric pressure value measured by another terminal, and compared with a method for determining the terminal height information only according to the measured barometric pressure value, because the standard height of the weather monitoring station is accurate, an error introduced when calculating the terminal height information can be reduced, thereby improving the accuracy of determining the terminal height information by another terminal.

The following describes in detail a manner in which the server determines the altitude information of the target terminal according to the first network identifier. In this embodiment, the location request further includes a signal strength of at least one wireless network station, and the signal strength of each wireless network station corresponds to one first network identifier.

Referring to fig. 10, a flowchart of a method for positioning a terminal according to another embodiment of the present application is shown, where the method includes:

Optionally, the intensity conditions include: the signal intensity is higher than the preset intensity and/or the signal intensities are ranked on the top k bits in the descending order.

In step 1002, the server obtains network height information corresponding to each of the k first network identifiers, to obtain k network height information.

After the server determines the network height information of each wireless network station according to the terminal height information, the server stores the corresponding relationship between the second network identification of the wireless network station and the network height information. For each first network identifier in the k first network identifiers, the server searches a second network identifier which is the same as the first network identifier in the corresponding relation, and determines the network height information corresponding to the second network identifier as the network height information of the first network identifier.

Schematically, referring to the corresponding relationship between the second network identifier and the network positioning information shown in fig. 11, assuming that k is 5, and the 5 first network identifiers determined by the server are MAC1, MAC2, MAC3, MAC4, and MAC5, the network positioning information corresponding to each MAC address can be obtained according to the corresponding relationship.

Illustratively, this step can be represented by the following formula:

wherein h is height information of the target terminal; r is_gIdentifying a corresponding signal strength for the g-th first network; h is_gAnd identifying corresponding network height information for the g-th first network.

In summary, in the embodiment, k first network identifiers whose signal strengths satisfy the strength condition are determined from at least one first network identifier; acquiring network height information corresponding to each first network identifier in the k first network identifiers; the closer the geographic positions of the target terminal and the wireless network station are, the higher the signal intensity of the corresponding wireless network station is, and at the moment, the server can determine the height information of the target terminal according to the k pieces of network height information which are closer to the target terminal, so that the accuracy of determining the height information of the target terminal by the server can be improved.
