Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

In the description of the present application, it is to be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, e.g. as being able to be fixedly connected, also being able to be detachably connected, or being integrally connected; can be a mechanical connection, but also an electrical connection; can be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present application can be specifically understood by those of ordinary skill in the art. Further, in the description of the present application, "a plurality" means two or more unless otherwise specified. "and/or" describes the association relationship of the associated objects, meaning that there can be three relationships, e.g., a and/or B, meaning that: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

In the related art, the commuting utilization rate of urban rail transit is higher and higher, and urban rail transit is mostly underground rails. Therefore, when the terminal is in a vehicle of rail transit, the positioning error for the terminal is large, and the accuracy is low.

In the related positioning technology, a mobile terminal commonly has Wifi positioning, GPS positioning, AGPS positioning or base station positioning, and the like, and most of current rail transit positioning uses GPS positioning or AGPS positioning; the basic principle of each technical positioning is briefly described as follows.

(1) Wifi localization principle: a method for measuring and calculating the link Signal Strength (RSSI) between nodes is adopted, and the transmission distance between the nodes is estimated by utilizing a wireless Signal space transmission attenuation model.

(2) GPS positioning principle: the distance between the navigation satellite with the known position and the user receiver is measured, and then the accurate position of the receiver is calculated by integrating the data of a plurality of navigation satellites. Wherein the receiver may be one of the terminals used by the user. For example, any one of the first terminal, the second terminal, and the candidate terminal.

(3) AGPS positioning principle: the AGPS technology is a technology that combines network base station information and GPS information to locate a mobile terminal, and can be used in an operator network.

(4) The positioning principle of the base station is as follows: the mobile communication base station positioning principle can be roughly divided into three types, namely a positioning technology based on trigonometric relation and operation, a positioning technology based on scene analysis and a positioning technology based on proximity relation.

(a) Positioning technology based on trigonometric relation and operation

And calculating the position of the measured object by using the geometric trigonometric relation according to the measured data.

(b) Positioning technology based on scene analysis

The positioning technology abstracts and formalizes a specific positioning environment, describes each position in the positioning environment by using some specific and quantized parameters, queries a database according to the characteristics of the position of an object to be positioned, and determines the position of the object according to a specific matching rule.

(c) Positioning technology based on proximity relation

Positioning is based on the proximity of the object to be positioned to one or more known locations. Such as Cell-ID in the network.

Schematically, in urban rail transit, due to the underground particularity of a rail, various positioning modes have limitations to judge a current position station through a mobile terminal, and the following description is provided.

The defects of the Wifi positioning technology depend on basic network deployment, cannot be used under the condition of no Wifi network, and is too high in cost. The GPS positioning technology has the defects that the GPS signal of an underground scene is easily shielded, and the position is easily drifted. The disadvantage of the base station positioning technology is that erroneous judgment easily occurs when a multi-cell signal coverage site is positioned, and positioning missing judgment and positioning erroneous judgment easily occur after a base station is changed. The AGPS positioning technology has the defects that the GPS signal of an underground scene is easily shielded, and the positioning drift phenomenon is easily generated. In order to solve the problem of difficulty in positioning a specific location (e.g., an underground space) in the prior art, embodiments of the present application provide a method for positioning a location where a terminal is located, which is described below.

In order to make the solution shown in the embodiments of the present application easy to understand, several terms appearing in the embodiments of the present application will be described below.

Code brushing recording: the record is generated by the code swiping operation performed by the terminal before entering the appointed place. In one scenario, the graphical code for which the swipe operation is directed can be a one-dimensional barcode, two-dimensional code, or other graphical code.

Optionally, the code-swiping record is a record of the terminal entering a track traffic station. For example, the terminal performs a code brushing record of code brushing on the gate before entering the subway station.

Optionally, the code-swiping record is a record of the terminal entering a specified location. For example, a terminal may need to scan a graphic code reflecting a designated location before entering a building, building or other enclosed space. For example, the terminal used by the user scans the graphic code of the O building before entering the O building. At this point, the terminal used by the user will keep the swipe record indicating that the terminal has entered building O.

And (3) specifying a place: is a space with a fixed geographical location. In one aspect, the designated location may be a subway station, a building, a hospital, an underground mall, or a basement, etc. On the other hand, the specified place may be a position having a fixed place on the map.

Local area network scanning information: information indicating a terminal establishing a local area network with a current terminal. For example, the local area network scanning information of the terminal a includes a terminal B, a terminal C and a terminal D. In this scenario, the local area network scanning information of the terminal a is used for indicating that the terminal a can perform information interaction with the terminal B, the terminal C and the terminal D in the local area network.

Local area network: a local area network established by a short-range wireless communication technology. In one case, the short-range wireless communication technology is bluetooth technology. Another possible scenario is wifi (Wireless Fidelity) and other short-range sensing technologies.

For example, the method for locating the location of the terminal shown in the embodiment of the present application may be applied to a terminal, where the terminal has a display screen and a function of locating the location of the terminal. The terminal can comprise a mobile phone, a tablet computer, smart glasses, a smart watch, a digital camera, an MP4 player terminal or an MP5 player terminal, and the like.

In a possible implementation manner, when the electronic device 100 is implemented as a mobile terminal, the electronic device can turn on a short-distance wireless communication component in the second electronic device when the second electronic device generates a code swiping record, where the code swiping record is a record of entering a specified place through an identification graphic code; acquiring local area network scanning information of the second electronic equipment through the short-distance wireless communication assembly, wherein the local area network scanning information is used for indicating the electronic equipment which forms a local area network with the second electronic equipment through the short-distance wireless communication assembly; and determining that the target place is the place where the second electronic equipment is located according to the local area network scanning information.

In another possible implementation manner, when the electronic device 100 is implemented as a server, the electronic device can acquire a candidate terminal with a code swiping record, where the code swiping record is a record of entering a specified place through an identification graph code; determining a first terminal with the minimum time interval between the code refreshing time and the current system from the candidate terminals, wherein the place where the first terminal is located is a target place; and when the local area network scanning information of the second terminal comprises the first terminal, determining the place where the second terminal is located as the target place.

Refer to FIG. 2, which is a block diagram illustrating an exemplary implementation environment according to an embodiment of the present application. In fig. 2, a server 210, a candidate terminal 220, a second terminal 230, and a target site 240 are included. The target site 240 is a site managed in a closed manner. Before each terminal enters the target site 240, a code swiping operation needs to be performed to generate a code swiping record.

In the embodiment shown in fig. 2, the terminals entering the target location 240 are all candidate terminals 220 that have completed the code-swiping operation and generated the corresponding code-swiping records. The server 210 can obtain the candidate terminal 220 at the time of the code swiping, and determine the candidate terminal 220 with the minimum time interval between the time of the code swiping and the current system time as the first terminal 221. Subsequently, the server 210 determines the location where the first terminal 221 is located according to the swipe record of the first terminal 221, and determines the location as the target location. When confirming that the first terminal 221 exists in the local area network scanning information of the second terminal 230, the server 210 determines the location where the second terminal 230 is located as the target location.

Referring to fig. 3, fig. 3 is a flowchart of a method for locating a location of a terminal according to an exemplary embodiment of the present application. The method for locating the location of the terminal can be applied to the server. In fig. 3, the method for locating the location of the terminal includes:

and step 310, acquiring a candidate terminal with a code swiping record, wherein the code swiping record is a record for entering a specified place through the identification graphic code.

In the embodiment of the application, the server can acquire the candidate terminal with the code swiping record. Alternatively, the candidate terminals collected by the server may be terminals having a specified characteristic.

In one possible implementation, the specified characteristic is entry into a target site. For example, if the feature that the code swiping record indicates to enter the subway station a is the specified feature, the server determines the terminal that the code swiping record indicates to enter the subway station a as the candidate terminal.

In another possible implementation, the specified feature is an abstract feature, and the feature is embodied by clustering the brushing records received by the server through a clustering model. The terminals corresponding to the brush code records which can be aggregated into a set by the clustering model are regarded as having the same specified characteristics.

And 320, determining a first terminal with the minimum time interval between the code swiping time and the current system time from the candidate terminals, wherein the place where the first terminal is located is a target place.

In the embodiment of the application, the server can determine the first terminal with the smallest code swiping time and the smallest current system time interval from the candidate terminals, and take the place corresponding to the code swiping record of the first terminal as the target place.

For example, the candidate terminals include terminal a, terminal B, terminal C, and terminal D. The current system time is 15:28: 30. Please refer to table one, which shows a candidate terminal code refreshing time and a difference value with the current system time.

As can be seen from the data shown in table one, the candidate terminals include four terminals, terminal a, terminal B, terminal C, and terminal D. And the code swiping moment of the terminal D is the terminal with the minimum time with the current system in the candidate terminals. Therefore, the server determines terminal D as the first terminal. Optionally, the code swiping information of the first terminal is shown in table two.

In table two, the code-swiping information of the first terminal includes an IMEI (International Mobile Equipment Identity), a Mobile phone number, a city name, a line (name), a site name, a code-swiping time, and gate information. The IMEI and the mobile phone number of the first terminal are used for identifying the identification information of the mobile phone, and the city name, the line (name), the station name, the code swiping time and the gate information of the first terminal can be directly generated after the code swiping operation is completed through the mobile phone and the subway gate.

It should be noted that the code swiping information shown in table two may be stored in the local memory of the first terminal after the first terminal completes the code swiping operation.

Step 330, when the local area network scanning information of the second terminal includes the first terminal, determining the location where the second terminal is located as the target location.

In the embodiment of the application, the server can identify the local area network scanning information received by the server. The local area network scanning information is used for indicating a terminal forming a local area network with the second terminal through the short-distance network cable communication component. See, for example, table three and table four. Table three is the local area network scanning information of the second terminal, and table four is the local area network scanning information of the fourth terminal.

Illustratively, the "bluetooth MAC of other device scanned" in table three and table four is one possible implementation of the local area network scanning information in the present application. If the identifier of the first terminal is MAC _ n1, the local area network scanning information of the second terminal shown in table three includes the first terminal, and the local area network scanning information shown in table four does not include the first terminal.

Optionally, the server may determine the location of the second terminal according to the code swiping information (i.e. the information in table two) of the second terminal. In table two, the station name corresponds to station a, that is, the location where the second terminal is located is subway station a.

In summary, in the method for locating a location of a terminal provided in this embodiment, a candidate terminal having a code swiping record is obtained, and a first terminal with a smallest code swiping time and a smallest current system time interval is determined in the candidate terminals, where the location of the first terminal is a target location, and when the local area network topology information of the second terminal includes the first terminal, the location of the second terminal is determined as the target location, and the code swiping record is a record of entering a specified location through an identification pattern code. According to the method and the device, the first terminal with the smallest code swiping time and the smallest current system time interval can be determined from the candidate terminals in the code swiping records, and when the local area network scanning information of the two terminals comprises the first terminal, the place where the second terminal is located is determined as the target place, so that the dependence of the terminal on positioning through network equipment is reduced, and the capability of the terminal in determining the current position is improved.

Based on the scheme disclosed in the previous embodiment, the terminal can also provide local area network scanning information so that the terminal can determine the location where the terminal is located, please refer to the following embodiments.

Please refer to fig. 4, which is a flowchart illustrating a method for locating a location of a terminal according to another exemplary embodiment of the present application. The method for locating the location of the terminal can be applied to the terminal. In fig. 4, the method for locating the location of the terminal includes:

and step 410, when the second terminal generates a code swiping record, starting a short-distance wireless communication component in the second terminal, wherein the code swiping record is a record for entering a specified place through the identification graphic code.

In the embodiment of the application, when the second terminal generates the code swiping record, the terminal starts a short-distance wireless communication component in the second terminal. It should be noted that the short-range wireless communication component may be one of a bluetooth component, a Wi-Fi component, or other short-range wireless communication components, which is not limited in this embodiment of the present application.

Optionally, when the second terminal completes the code swiping operation, the second terminal will generate the code swiping record. In one possible approach, the flush record will be stored in a local memory of the second terminal.

And step 420, acquiring local area network scanning information of the second terminal through the short-distance wireless communication component, wherein the local area network scanning information is used for indicating a terminal forming a local area network with the second terminal through the short-distance wireless communication component.

In the embodiment of the application, the second terminal can scan through the short-distance wireless communication component, and scan the information of other terminals which can communicate with the second terminal in the periphery. In this scenario, the information of the other terminal capable of communicating with the second terminal is local area network scan information.

In a possible implementation manner, the local area network scanning information of the second terminal is [ bluetooth MAC1, bluetooth MAC2, bluetooth MAC3, and bluetooth MAC4 ], which indicates that other terminals connected to the second terminal through bluetooth include terminals corresponding to the above 4 bluetooth MAC identifiers.

In another possible implementation manner, the local area network scanning information of the second terminal is [ SSID 1, SSID 2, SSID 3, and SSID 4 ], which illustrates that other terminals connected to the second terminal through the Wi-Fi technology include terminals corresponding to the 4 SSIDs (Service Set identifiers).

It should be noted that, in the embodiments of the present application, the local area network scanning information can also be determined by scanning the surrounding terminals through other short-range wireless communication components.

And 430, determining that the target place is the place where the second terminal is located according to the local area network scanning information, wherein the target place is the place where the first terminal is located, and the first terminal is the terminal with the smallest time interval between the code swiping moment and the current system.

In the embodiment of the application, the second terminal can determine that the target place is the place where the second terminal is located according to the local area network scanning information. Alternatively, the terminal can determine the location of itself in two ways. The two modes comprise an online positioning mode and an offline positioning mode.

Illustratively, the online positioning mode is used to indicate a positioning mode in which the server participates. In the method, the second terminal sends the local area network scanning information to the server, and the server determines the target place as the place where the second terminal is located according to the local area network scanning information.

Illustratively, the offline positioning mode is used to indicate a positioning mode without server participation. In the method, the second terminal determines the first terminal by itself according to the local area network scanning information and the received code swiping records of other terminals, and further determines the target place.

In summary, the method for locating a location of a terminal according to this embodiment can start a short-range wireless communication module in a second terminal when the second terminal generates a code-swiping record, acquire local area network scanning information of the second terminal through the short-range wireless communication module, and determine a target location as the location of the second terminal according to the local area network scanning information, where the local area network scanning information is used to indicate a terminal that forms a local area network with the second terminal through the short-range wireless communication module, the target location is a location of a first terminal, and the first terminal is a terminal with a minimum code-swiping time and current system time interval. According to the embodiment of the application, the current location can be determined in a data sharing mode, and the location of the terminal can be positioned under the scene that the terminal is not in network connection with the server. Therefore, the method and the device for locating the terminal can improve the ability of the terminal to locate the place of the terminal.

Referring to fig. 5, fig. 5 is a flowchart of a method for locating a location of a terminal according to an exemplary embodiment of the present application. The method for positioning the location of the terminal can be cooperatively completed by the server and the second terminal. In fig. 5, the method for locating the location of the terminal includes:

Optionally, the user of the second terminal needs to perform a code swiping operation when entering the designated place. In one possible approach, the second terminal entering the designated location is a station of rail transit. In another possible approach, the second terminal enters the designated location as a building, or other location.

As another possible implementation manner, the user of the second terminal may also enter a designated place by swiping an identification card, and the like, which is not limited in this embodiment of the application.

In one possible approach, the venue-resident event includes, but is not limited to, at least one of a timer event, an IMU (Inertial measurement unit) information change event, or an audio information event.

Illustratively, a timer event is an event that is automatically triggered after a specified length of time has elapsed. E.g., a 20 second timer event, an automatically triggered event that indicates 20 seconds have elapsed after the second terminal completes the code swipe operation.

Illustratively, an IMU information change event is a change of information received by the IMU to a specified value. For example, when the acceleration value measured by the IMU changes to the value at the start of the subway, the IMU information change event is triggered.

Illustratively, an audio information event is an event triggered by the receipt of specified audio. For example, the audio information event may be an event triggered by the terminal receiving audio of an imminent subway start or an imminent subway door close.

Step 513, when the location-resident event is triggered, the second terminal starts a short-range wireless communication component in the second terminal.

And step 520, the second terminal acquires the local area network scanning information of the second terminal through the short-distance wireless communication component.

In the embodiment of the present application, after the completion step 520 is performed, step 530 to step 570 can be performed, and step 581, step 582, and step 583 can also be performed.

Alternatively, the second terminal can adaptively select to perform steps 530 to 570, or perform

steps

581, 582, and 583 according to the network condition currently connected to the server. When the network condition of the second terminal and the server is clear, the second terminal side and the server side may cooperatively configure and execute steps 530 to 570. When the network condition of the second terminal and the server connection is not clear, the second terminal side and the server side may cooperatively configure to perform step 581, step 582 and step 583.

Step 530, the second terminal sends the local area network scanning information to the server.

Step 541, the server receives the swipe code record uploaded by the candidate terminal.

The code swiping record comprises identification information of the candidate terminal and code swiping behavior related information.

Optionally, the swipe behavior related information includes a swipe time and a name of the target location.

In step 542, the server receives the local area network scanning information uploaded by the candidate terminal.

The local area network scanning information comprises identification information, local area network identification and scanned terminal identification.

In step 551, the server obtains the candidate terminal with the code swiping record.

In step 552, the server determines a first terminal with the smallest time interval between the code swiping time and the current system time from the candidate terminals.

In step 553, when the local area network scanning information of the second terminal includes the first terminal, the server determines the location where the second terminal is located as the target location.

And step 560, the server sends the information of the target place to the second terminal.

Step 570, the second terminal updates the location information of itself to the target location.

Step 581, the third terminal is determined according to the local area network scanning information.

The third terminal and the second terminal form a terminal of a local area network.

In step 582, the target terminal with the smallest time interval between the code swiping time and the current system time is determined from the third terminals.

Optionally, in a possible manner, the second terminal performs data interaction with the third terminal through the installed designated application. Wherein the third terminal can install the same designated application as the second terminal. And the designated applications are automatically connected through a preset communication protocol. The connection key for specifying the application may be a predetermined fixed key or a dynamic key automatically generated according to a predetermined generation rule.

And step 583, determining the location of the target terminal as the location of the second terminal.

In summary, the method for locating the location of the terminal provided in this embodiment can determine the location of the terminal in an online location manner with participation of the server, and can also determine the location of the terminal in an offline location manner without participation of the server. Because the terminal at the determined location can not perform operations such as code scanning and the like, the location can be realized in a mode of sharing data with surrounding terminals when the terminal is not connected with a server, and the capability of the terminal in locating the location is improved.

Referring to fig. 6, fig. 6 is a flowchart illustrating a method for locating a location of a terminal online according to an embodiment of the present application. The scheme shown in fig. 6 is described by taking a scene applied in rail transit as an example.

In fig. 6, it is assumed that there is a subway line, and the subway moves from station a to station B, and then from station B to station C. In the subway station A, a user A enters the subway station A in a mobile phone code swiping mode. In the subway station B, a user B enters the subway station B in a mobile phone code swiping mode. In the subway station C, a user C enters the station through mobile phone code swiping.

In stage 1 of the scenario shown in FIG. 6, user A swipes his code from site A and proceeds to block 610, described below.

Step 611, the mobile phone of the user a swipes a code from the site a to enter the site, and the site information is cached locally.

Illustratively, the storage format of the station information is as shown in table five below.

The gate information in table five is optional information, and may not appear in the site information. The first row of table five is to store key information including, but not limited to, IMEI, cell phone number, city name, line, site name, time to swipe, and gate information. The second row of table five is the hypothetical field value collected when user a swiped.

When the site resident event triggers, the bluetooth module is enabled, step 612.

Illustratively, there is a distance from the moment of code swiping for user a to the arrival of the subway car. In this application, the terminal of user a does not start bluetooth during this period. When the venue-resident event triggers, the bluetooth component is enabled. Wherein the place resident event is used for indicating that the user A arrives at the position of the subway platform.

Step 613, scanning the surrounding bluetooth terminals.

Illustratively, the terminal of user a will continue to obtain bluetooth MAC information from the other device for a duration T1, which is stored in the format shown in table six.

In table six, the first row is the key information for bluetooth scan (including but not limited to IMEI, phone number, native bluetooth MAC, other device bluetooth MAC scanned), and the second row is the field value scanned by the terminal bluetooth of user a.

And 614, packaging and uploading the code refreshing record and the local area network scanning information.

In this embodiment of the application, if the user a uploads the information to the server, when the local area network scanning information is subsequently uploaded, only the newly scanned bluetooth MAC of the other device needs to be uploaded.

Step 615, the bluetooth module of the terminal of user a is turned off.

In stage 2 of the scenario shown in fig. 6, module 620 is run with reference to user B swiping a code from site B, as described below.

Step 621, refer to user B to enter the station by using the terminal swipe code.

Illustratively, the terminal of reference user B caches the site information locally. In one possible approach, the site information obtained with reference to the terminal of user B is shown in table seven.

At step 622, the bluetooth component is enabled when the site resident event triggers.

Step 623, scanning surrounding Bluetooth terminals.

Illustratively, the terminal of user B will continue to obtain bluetooth MAC information of the other device for a duration T1, and the storage format is as shown in table eight.

And step 624, packaging the uploading code-swiping record and the local area network scanning information to the cloud server.

Step 625, close the bluetooth module of the terminal of user B.

Illustratively, in phase 2 of the embodiment of the present application, the user a arrives at the station B in a subway. The terminal of user a executes module 630.

Step 631, when the place-resident event triggers, the bluetooth component is enabled.

Optionally, the venue-resident event is used to instruct user a's terminal to arrive at a subway station.

Step 632, scan the surrounding bluetooth terminals.

For illustration, please refer to table nine, which shows bluetooth MAC information of other devices scanned by the terminal of the user a.

And step 633, packaging and uploading the code brushing record and the local area network scanning information to a cloud server.

Step 634, current site information is obtained from the cloud server.

In the embodiment of the application, the terminal of the user A can wait for an interaction result with the cloud server and can actively initiate a request to acquire the current site information.

On the cloud server side, a matching step 640 can be performed with reference to user B.

In step 640, it is determined whether the terminal of user a matches the terminal of reference user B.

Illustratively, the terminal of user B may determine whether it is the first terminal that can be the terminal of user a according to the following logic.

(1) And judging whether the quasi-reference user has the code swiping record, wherein the quasi-reference user containing the code swiping record is used as a candidate terminal, and the quasi-reference user not containing the code swiping record is not selected as the candidate terminal.

(2) And when the quasi-reference user has a code swiping record, calculating the code swiping time difference of each candidate terminal.

Wherein, the time difference is the current system time-the code swiping time of each user.

(3) When the quasi-reference user has the code swiping record, judging whether the code swiping time difference is smaller than a time threshold T, if so, taking the quasi-reference user as a candidate of the reference user, and if not, taking the quasi-reference user as a candidate of the reference user.

(4) And selecting the terminal with the minimum time difference as the first terminal.

In the embodiment of the application, after the cloud server determines the first terminal, the cloud server feeds back the code brushing site information of the first terminal to the user A, so that the site where the user A is located currently is determined. For example, the code swiping site information of the user B is fed back to the user a, so that the user a can know that the current site is the site B.

In phase 3 of the present application, referring to the terminal of user C being able to execute the module 610 located in the terminal, the terminal of user a will run the module 630, while the terminal of user a will also run the module 630. And analogizing in sequence until the subway operation is finished, so that each terminal can position the station where the terminal is located.

In the subway station C, a user C enters the station through mobile phone code swiping.

In the scheme shown in fig. 7, accurate site information is acquired by a user through mobile phone code swiping for entering, bluetooth of each terminal card passes through a temporary local area network formed by terminals, each terminal exchanges site information through the local area network, and a first terminal is selected according to rules to determine a current target place, namely site information.

In stage 1 of the scenario shown in fig. 7, user a swipes his code from site a and enters the site, running block 710, described below.

Step 711, the terminal of the user a swipes the code from the site a to enter the site, and the site information is cached locally.

Illustratively, the storage format of the station information is as shown in table ten below.

At step 712, the terminal of user a enables the bluetooth component when the venue-dwelling event triggers.

Step 713, after the bluetooth module is turned on, the terminal of the user a scans the bluetooth terminals in the peripheral range to form a temporary local area network, and the temporary local area network lasts for a period Tx.

In step 714, the terminal of user a distributes its own site information to other users.

Illustratively, the terminal of user a does not receive information distributed by other users. The format of information distributed by the terminal of user a is shown in table eleven.

And step 715, after the terminal of the user A finishes data distribution, the Bluetooth assembly is closed.

In stage 2 of the scenario shown in fig. 7, module 720 is run with reference to user B swiping a code from site B to enter, as described below.

In step 721, the reference user B uses the terminal to swipe the code into the station, and the station information is cached locally.

Illustratively, the site information obtained with reference to user B is shown in table twelve.

At step 722, the bluetooth component is enabled when the venue-resident event triggers.

Step 723, after the bluetooth component is turned on, the terminal of the user B scans the bluetooth terminals in the peripheral range to form a temporary local area network, which lasts for a period Tx.

In step 724, the terminal of user B distributes its own site information to other users.

In step 725, the terminal of user B turns off the bluetooth module.

Illustratively, in phase 2 of the embodiment of the present application, the user a arrives at the station B in a subway. The terminal of user a executes module 730.

In step 731, the bluetooth component is enabled when the site resident event triggers.

In step 732, after the bluetooth module is turned on, the terminal of user a scans the bluetooth terminals in the peripheral area to form a temporary local area network, and lasts for a period of time Tx.

In step 733, the terminal of user a synchronously refers to the site information distributed by the terminal of the user, as shown in table thirteen.

In step 734, the terminal of user a turns off the bluetooth module.

The terminal of user a will be able to determine the location of the terminal, step 735.
