Description

Position determination method and device

Technical Field

The present application relates to the field of terminal technologies, and in particular, to a method and an apparatus for determining a location.

Background

In a Secure User Plane Location (SUPL) assisted location protocol, a SUPL location server reports a location identity (location ID) of a terminal supporting SUPL capability through the terminal, thereby assisting the terminal in acquiring its location.

When the terminal is assisted to acquire the position of the terminal, if the position calculated by the SUPL positioning server meets the precision condition, the calculated position is directly sent to the terminal, and the position is the position of the terminal. And if the position calculated by the SUPL positioning server does not meet the precision condition, sending the reference position of the terminal and the corresponding auxiliary data to the terminal so that the terminal determines the position according to the reference position and the corresponding auxiliary data.

However, in the existing method, the location identifier (location ID) reported by the terminal to be located is often not rich and comprehensive enough, so that the SUPL location server may not obtain the terminal location closer to the actual location, thereby resulting in a lower accuracy of the obtained terminal location.

These drawings and written description are not intended to limit the scope of the disclosed concepts in any way, but rather to illustrate the concepts of the disclosure to those skilled in the art by reference to specific embodiments.

Detailed Description

The technical scheme provided by the embodiment of the application can be applied to the positioning scenes of second generation (2th generation, 2G), third generation, fourth generation and fifth generation communication systems, or can also be applied to the positioning scenes of other communication systems which may appear in the future. It should be noted that, when the technical solution provided in the embodiment of the present application is applied to the positioning scenarios of the above several possible communication systems, names of the positioning server and the terminal may change, but this does not affect implementation of the technical solution provided in the embodiment of the present application.

In the embodiments of the present application, "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. In the description of the text of the present application, the character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

Taking the application of the technical solution provided in the embodiment of the present application to the SUPL auxiliary positioning scenario as an example, for a certain terminal supporting SUPL capability, when receiving a location request through a certain application installed therein, a current location of the certain terminal needs to be obtained. In the prior art, when acquiring the location of a terminal, the terminal may report a location identifier (location ID) of the terminal to an SUPL location server, and the SUPL location server determines the location of the terminal according to the location identifier reported by the terminal. And if the position calculated by the SUPL positioning server meets the precision condition, directly sending the calculated position to the terminal, wherein the position is the position of the terminal. And if the position calculated by the SUPL positioning server does not meet the precision condition, sending the reference position of the terminal and the corresponding auxiliary data to the terminal so that the terminal determines the position according to the reference position and the corresponding auxiliary data. However, in the existing method, the location identifier (location ID) reported by the terminal to be located is often not rich and comprehensive enough, so that the SUPL location server may not obtain the terminal location closer to the actual location, thereby resulting in a lower accuracy of the obtained terminal location.

In order to improve the accuracy of the terminal location acquired by the SUPL server, an easily conceivable technical solution is: on one hand, when the terminal reports the positioning identifier, the terminal can report the more accurate positioning identifier as much as possible; on the other hand, the SUPL location server calculates and determines the location of the terminal according to the location identifier reported by the terminal, and may optimize the algorithm as much as possible to improve the accuracy of the obtained location of the terminal. By adopting the scheme, although the accuracy of the acquired terminal position can be improved to a certain extent, the accuracy improvement capability is limited because the position of the terminal is determined according to the own positioning identifier reported by the terminal.

In order to improve the accuracy of the terminal position acquired by the SUPL server, please refer to fig. 1, where fig. 1 is a schematic diagram of an application scenario provided in an embodiment of the present application when determining the position of the terminal to be positioned, a user plane SUPL auxiliary positioning system shown in the application scenario may include a terminal to be positioned and M peripheral terminals, and both the terminal to be positioned and the M peripheral terminals may directly communicate. Based on the scenario shown in fig. 1, an embodiment of the present application provides a position determining method, where the position determining method may include: the terminal to be positioned firstly acquires the area information of the M peripheral terminals; after the area information of the M peripheral terminals is acquired, the target position of the terminal to be positioned is determined according to the positioning identifier of the terminal to be positioned and the acquired area information of the M peripheral terminals, so that the position of the positioning terminal is acquired. M is an integer greater than or equal to 1.

It can be understood that, in the embodiment of the present application, one peripheral terminal may have a plurality of positioning identifiers, and a terminal to be positioned may have a plurality of positioning identifiers. For example, the positioning identifier of the terminal may be a cell identifier of the terminal, a Wi-FiAP MAC address, and/or a neighbor cell identifier of the cell of the terminal, and may be specifically set according to actual needs. Illustratively, the LOCATION identification (LOCATION ID) may be one or more of GSM Cell Info, WCDMA/TD-SCDMA Cell Info, CDMACell Info HRPD Cell Info, UMB Cell Info, LTE Cell Info, WLAN AP Info, WiMAX BSInfo, NR Cell Info. Other peripheral terminals may be terminals within a Near Field Communication (NFC) connection range of a terminal to be positioned, terminals within a bluetooth connection range, terminals within a Wi-Fi connection range, or terminals within a 4G or 5G direct communication connection range.

Therefore, according to the position determining method provided by the embodiment of the application, when the position of the terminal to be positioned is determined, the area information of the M peripheral terminals which can be directly communicated with the terminal to be positioned is obtained, the area information comprises the positioning identification and/or the position, the target position of the terminal to be positioned is determined according to the positioning identification of the terminal to be positioned and the area information of the M peripheral terminals, that is, the target position of the terminal to be positioned is determined according to the positioning identification of the terminal to be positioned and the area information of the M peripheral terminals corresponding to the terminal to be positioned, and the target position of the terminal to be positioned is determined according to the positioning identification of the terminal to be positioned and the area information of the M peripheral terminals, so that the accuracy of the obtained terminal position is improved.

It can be understood that when the target position of the terminal to be positioned is determined according to the positioning identifier of the terminal to be positioned and the area information of the M peripheral terminals, two possible scenarios may be included, and in one possible scenario, the terminal to be positioned may determine the target position of the terminal to be positioned according to the positioning identifier of the terminal to be positioned and the acquired area information of the peripheral terminals, so that it can be seen that, in this scenario, the terminal does not need to interact with the positioning server, and the determination operation of the target position may be completed independently; in another possible scenario, due to the limited computing capability of the terminal to be positioned, the terminal to be positioned may send the positioning identifier and the acquired area information of the peripheral terminal to the positioning server, so as to assist the terminal to be positioned to calculate and determine the target position of the terminal to be positioned through the positioning server.

Hereinafter, the position determining method provided in the embodiment of the present application will be described in detail with respect to the two possible scenarios, respectively. It is understood that, in the embodiments of the present application, the following specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

In a possible scene, the terminal to be positioned does not need to interact with a positioning server, and the determination operation of the target position is independently completed. For example, please refer to fig. 2, where fig. 2 is a schematic flowchart of a position determining method provided in an embodiment of the present application, where the position determining method may include:

s201, acquiring area information of M peripheral terminals corresponding to the terminal to be positioned.

The area information comprises positioning marks and/or positions, M peripheral terminals can be directly communicated with the terminal to be positioned, and M is an integer greater than or equal to 1.

Before acquiring the region information of M peripheral terminals corresponding to a terminal to be positioned, business connection needs to be established between the terminal to be positioned and the M peripheral terminals; after the service connection is established with the M peripheral terminals, the terminal to be positioned can respectively acquire the area information of each peripheral terminal in the M peripheral terminals based on the established service connection. If the terminal to be positioned has established service connection with the M peripheral terminals, the area information of the M peripheral terminals corresponding to the terminal to be positioned can be directly acquired.

After acquiring the area information of the M peripheral terminals corresponding to the terminal to be positioned, respectively, the target position of the terminal to be positioned may be determined according to the positioning identifier of the terminal to be positioned and the area information of the M peripheral terminals, that is, the following S202 is executed:

s202, determining the target position of the terminal to be positioned according to the positioning identification of the terminal to be positioned and the area information of the M peripheral terminals.

For example, if the obtained area information of the peripheral terminal includes the positioning identifier, when determining the target position of the terminal to be positioned, the positions corresponding to the positioning identifier of the terminal to be positioned and the positioning identifiers of the M peripheral terminals may be determined first, respectively, in a manner of searching a database according to the positioning identifier of the terminal to be positioned and the positioning identifiers of the peripheral terminals; the terminal to be positioned can determine the position of the terminal to be positioned according to the effective position corresponding to the positioning identifier through an algorithm, for example, the position corresponding to the positioning identifier of the terminal to be positioned and the positions corresponding to the positioning identifiers of M peripheral terminals can be fitted, so that the target position of the terminal to be positioned is obtained. If the acquired region information of the peripheral terminal includes a position, when determining the target position of the terminal to be positioned, the target peripheral terminal with the closest distance to the terminal to be positioned may be determined among the M peripheral terminals according to the positioning identifier of the terminal to be positioned, and the position of the target terminal is determined as the target position of the terminal to be positioned, thereby determining the target position of the terminal to be positioned.

Therefore, according to the position determining method provided by the embodiment of the application, when the position of the terminal to be positioned is determined, the area information of the M peripheral terminals which can be directly communicated with the terminal to be positioned is obtained, the area information comprises the positioning identification and/or the position, the target position of the terminal to be positioned is determined according to the positioning identification of the terminal to be positioned and the area information of the M peripheral terminals, that is, the target position of the terminal to be positioned is determined according to the positioning identification of the terminal to be positioned and the area information of the M peripheral terminals corresponding to the terminal to be positioned, and the target position of the terminal to be positioned is determined according to the positioning identification of the terminal to be positioned and the area information of the M peripheral terminals, so that the accuracy of the obtained terminal position is improved. In addition, the response time of the acquired target position is also improved.

The above-mentioned embodiment shown in fig. 2 describes in detail that, in a possible scenario, the terminal to be positioned does not need to interact with the positioning server, and the determination operation of the target position is independently completed. In another possible scenario, the terminal needs to interact with the positioning server to assist the determination of the target position by the positioning server. For example, please refer to fig. 3, where fig. 3 is a schematic flowchart of another position determining method provided in the embodiment of the present application, where the position determining method may include:

s301, when the terminal to be positioned receives the position request, acquiring the area information of N peripheral terminals corresponding to the terminal to be positioned.

The position request is used for requesting the position of the terminal to be positioned, the area information comprises a positioning identifier and/or a position, and the N peripheral terminals can be directly communicated with the terminal to be positioned.

For example, the terminal to be located may receive a location request from an operating application, and if the location request is received, it indicates that the current location of the terminal needs to be acquired currently. For the terminal to be positioned, after receiving the position request, the terminal can establish data connection with the positioning server; the terminal to be positioned can establish service connection with the N peripheral terminals while establishing data connection, and respectively acquire the area information of each peripheral terminal in the N peripheral terminals based on the established service connection; if the terminal to be positioned has established data connection with the positioning server and has established service connection with the N peripheral terminals, the area information of the N peripheral terminals corresponding to the terminal to be positioned can be directly acquired.

After acquiring the area information of the N peripheral terminals corresponding to the terminal to be positioned, the terminal to be positioned may carry the positioning identifier of the terminal to be positioned and the area information of the N peripheral terminals in the start message to send to the positioning server, that is, the following S302 is executed:

s302, the terminal to be positioned sends an initial message to the positioning server.

The initial message comprises a positioning identifier of the terminal to be positioned and area information of N peripheral terminals. The initial message is used for indicating the positioning server to determine the position of the terminal to be positioned according to the positioning identifier of the terminal to be positioned and the area information of the N peripheral terminals. In the embodiment of the present application, a terminal to be positioned sends an initial message to a positioning server, and the function of the terminal to be positioned is as follows: the positioning server is used for starting a positioning session between the terminal to be positioned and the positioning server.

For example, the START message may be a SUPL START message, which may include a session identifier, SET capabilities, and the like, in addition to the location identifier of the terminal to be located and the area information of the N peripheral terminals, and the SET capabilities include supported location methods, such as SET-assisted a-GPS, SET-based a-GPS, and related location protocols, such as Radio Resource location service Protocol (RRLP), Radio Resource Control (RRC), TIA-801, or LTE positioning Protocol (LTE positioning Protocol, LPP)/LTE positioning Protocol extensions (LPP extensions, LPPe), and the like.

When the positioning identifier of the terminal to be positioned and the area information of the N peripheral terminals are carried in the initial message and sent to the positioning server, the positioning identifier of the terminal to be positioned and the area information of the N peripheral terminals may be sequentially included in the initial message, that is, the area information of the N peripheral terminals is placed behind the positioning identifier of the terminal to be positioned. As for the area information of the N peripheral terminals, the closer the peripheral terminal is to the terminal to be positioned among the N peripheral terminals, the earlier the position in the start message is, it can be understood that the closer the distance to the terminal to be positioned is, the higher the priority is, and the earlier the corresponding position in the start message is. It can be understood that, in the embodiment of the present application, when the location identifier of the terminal to be located and the area information of the N peripheral terminals are carried in the start message and sent to the location server, the format of the location identifier of the terminal to be located and the area information of the N peripheral terminals needs to comply with the protocol of OMA-TS-ULP V2.0.5 and subsequent evolution.

It should be noted that, in this embodiment of the present application, when acquiring the area information of the N peripheral terminals, the terminal to be positioned may record the timestamp for acquiring the area information of the peripheral terminals together, so that when the acquired area information of the N peripheral terminals is carried in the start message and sent to the positioning server, the area information of the N peripheral terminals may be first screened according to the screening rule to obtain the area information of the peripheral terminals meeting the screening rule, and the area information of the peripheral terminals meeting the screening rule is carried in the start message and sent to the positioning server, so that the positioning server determines the location of the terminal to be positioned according to the positioning identifier of the terminal to be positioned and the area information of the peripheral terminals meeting the screening rule in the N peripheral terminals; certainly, in order to reduce the data processing amount of the terminal to be positioned, after acquiring the area information of the N peripheral terminals, the terminal to be positioned may also directly carry the area information of the N peripheral terminals in the initial message to send to the positioning server, so that the positioning server screens the area information of the N peripheral terminals according to the screening rule to obtain the area information of the peripheral terminals meeting the screening rule, and calculates and determines the position of the terminal to be positioned according to the positioning identifier of the terminal to be positioned and the area information of the peripheral terminals meeting the screening rule.

Illustratively, the screening rules include at least one of: whether the positioning identifier of the peripheral terminal is the same as the identifier of the terminal to be positioned, whether the positioning identifier of the peripheral terminal meets network information supported by the positioning server, or whether the difference between the acquisition time of the positioning identifier of the peripheral terminal and the current time is smaller than a preset threshold, and of course, other screening conditions may also be included. It can be understood that, when the screening rule includes whether the positioning identifier of the peripheral terminal is the same as the identifier of the terminal to be positioned, if the positioning identifier of the peripheral terminal is not the same as the identifier of the terminal to be positioned, it indicates that the positioning identifier of the peripheral terminal meets the screening condition, the positioning identifier of the peripheral terminal may be carried in the initial message to be sent to the positioning server, and conversely, if the positioning identifier of the peripheral terminal is the same as the positioning identifier of the terminal to be positioned, it indicates that the positioning identifier of the peripheral terminal is repeated, the positioning identifier of the peripheral terminal is discarded; when the screening rule includes whether the positioning identifier of the peripheral terminal meets the network information supported by the positioning server, if the positioning identifier of the peripheral terminal meets the network information supported by the positioning server, the positioning identifier of the peripheral terminal is indicated to meet the condition screening condition, the positioning identifier of the peripheral terminal can be carried in the initial message to be sent to the positioning server, and if the positioning identifier of the peripheral terminal does not meet the network information supported by the positioning server, the positioning identifier of the peripheral terminal is indicated to not meet the condition screening condition, the positioning identifier of the peripheral terminal is discarded; when the screening rule includes whether the difference value between the acquisition time of the positioning identifier of the peripheral terminal and the current time is less than a preset threshold value, if the difference value between the acquisition time of the positioning identifier of the peripheral terminal and the current time is less than the preset threshold value, it indicates that the area information of the peripheral terminal meets the condition screening condition, considering the positioning identifier of the peripheral terminal as the current value, the positioning identifier of the peripheral terminal can be carried in the initial message and sent to the positioning server, conversely, if the difference between the acquisition time of the positioning identifier of the peripheral terminal and the current time is greater than or equal to the preset threshold, it indicates that the positioning identifier of the peripheral terminal does not satisfy the condition screening condition, then, the location identifier of the peripheral terminal is considered as a non-Current value, and the location identifier of the peripheral terminal may be discarded or carried in the initial message to a certain extent (marked as "Not Current" state) to be sent to the location server. If the terminal to be positioned has no position, but the area information of the peripheral terminal has a position, a theoretically closest position (as shown in fig. 1, different access technologies have different operating distances) is selected to be carried in the initial message and sent to the positioning server.

In this embodiment of the present application, assuming that the terminal to be positioned filters the acquired region information of the N peripheral terminals according to the filtering rule before sending the start message, and after the filtering, it is determined that the region information of the N peripheral terminals all satisfy the filtering rule, the acquired region information of the N peripheral terminals is carried in the start message and sent to the positioning server, so that the positioning server determines the position of the terminal to be positioned according to the received positioning identifier of the terminal to be positioned and the region information of the N peripheral terminals, that is, the following S303 is executed:

s303, the positioning server determines the position of the terminal to be positioned according to the positioning identification of the terminal to be positioned and the area information of the N peripheral terminals.

For example, if the obtained area information of the peripheral terminal includes the positioning identifier, when the positioning server determines the position of the terminal to be positioned according to the positioning identifier of the terminal to be positioned and the positioning identifiers of the N peripheral terminals, the positioning server searches a database according to the positioning identifier of the terminal to be positioned and the positioning identifiers of the peripheral terminals, and obtains effective positions corresponding to the positioning identifiers, and if the positioning identifiers cannot be retrieved from the database, the effective positions cannot be obtained. The positioning server determines the position of the terminal to be positioned from the valid position corresponding to the positioning identifier and the position (if any) obtained from the message by means of an algorithm. It can be understood that the more location data the positioning server algorithm processes, the more accurate the position of the terminal to be positioned is theoretically obtained.

After the position of the terminal to be positioned is determined, whether the position of the terminal to be positioned meets a preset precision condition or not can be judged and determined, and if the determined position of the terminal to be positioned meets the preset condition, the following steps S307-S308 are directly executed; on the contrary, if the determined position of the terminal to be positioned does not satisfy the preset condition, the following step S304 is directly executed:

s304, the positioning server sends a response message to the terminal to be positioned.

The response message is used to instruct the terminal to be positioned to continue the next operation, and includes uploading the positioning identifier of the terminal to be positioned and the area information of M peripheral terminals, where the M peripheral terminals are not identical to the N peripheral terminals in S302. For example, the RESPONSE message may be a SUPL RESPONSE message, which may further include a session ID and a posmethod, and of course, may also include network information supportable by the location server, and the terminal to be located stores the network information supportable by the location server, which may be used as a condition in the screening rule for the next screening.

When the determined position of the terminal to be positioned does not meet the preset precision, the positioning server sends a response message to the terminal to be positioned, and after receiving the response message sent by the positioning server, the terminal to be positioned executes the following step S305:

s305, the terminal to be positioned sends a positioning initial message to the positioning server.

The initial positioning message comprises a positioning identifier of the terminal to be positioned and area information of M peripheral terminals. As an example, the location initiation message may be a SUPL POS INIT message. The SUPL POS INIT message may also include session ID, SET capabilities. SET capabilities include supported positioning methods, e.g., SET-assisted A-GPS positioning methods, SET-based A-GPS positioning methods, and related positioning protocols, e.g., RRLP, RRC, TIA-801, or LPP/LPPe. The SET may include a first SUPL POS element in the SUPL POS INIT message, in which the SET may SET the requested assistance data element. It should be noted that, in this embodiment of the application, after sending the area information including the N peripheral terminals to the positioning server, the terminal to be positioned does not stop obtaining the area information of the peripheral terminals, and continues to obtain the area information of the peripheral terminals while receiving the response message, and determines the area information of the M peripheral terminals included in the initial positioning message based on the obtained area information of the peripheral terminals.

For example, the location initial message may include, in addition to the location identifier of the terminal to be located and the area information of the M peripheral terminals, an initial position of the terminal to be located, and although the initial position may be a position with lower accuracy, the initial position may still be carried in the location initial message and sent to the location server. It should be noted that, in this embodiment of the application, if the longitude and latitude are stored in the terminal to be positioned, the longitude and latitude are determined as the initial position of the terminal to be positioned, and if the longitude and latitude are not stored in the terminal to be positioned but the area information of the other M peripheral terminals includes a position, the position of the peripheral terminal closest to the terminal to be positioned in the M peripheral terminals is determined as the initial position of the terminal to be positioned.

In the embodiment of the application, taking the positioning initial message as an example that the positioning initial message includes the positioning identifier of the terminal to be positioned and the area information of M peripheral terminals, when the area information of the M peripheral terminals is determined according to the acquired area information of the peripheral terminals, assuming that the terminal to be positioned first acquires the area information of P peripheral terminals corresponding to the terminal to be positioned, the area information of the P peripheral terminals can be screened according to the screening rule, and the area information of the peripheral terminals which do not meet the screening rule is removed to obtain the area information of the M peripheral terminals, where the M peripheral terminals are part of or all the P peripheral terminals; and then sending the positioning identification of the terminal to be positioned and the area information of the M peripheral terminals obtained by screening to a positioning server. Certainly, in order to reduce the data processing amount of the terminal to be positioned, after acquiring the area information of the P peripheral terminals, the terminal to be positioned may also directly send the positioning identifier of the terminal to be positioned and the area information of the P peripheral terminals to the positioning server, so that the positioning server screens the area information of the P peripheral terminals according to the screening rule to obtain the area information of the peripheral terminals meeting the screening rule, and calculates and determines the position of the terminal to be positioned according to the positioning identifier of the terminal to be positioned and the area information of the peripheral terminals meeting the screening rule.

In the embodiment of the present application, it is assumed that before the terminal to be positioned sends the initial positioning message, the obtained region information of the P peripheral terminals has been screened according to the screening rule, so as to obtain the region information of the M peripheral terminals. When the positioning identifier of the terminal to be positioned and the area information of the M peripheral terminals are carried in the initial message and sent to the positioning server, the positioning identifier of the terminal to be positioned and the area information of the M peripheral terminals may be sequentially included in the initial positioning message, that is, the area information of the M peripheral terminals is placed behind the positioning identifier of the terminal to be positioned. For the area information of the M peripheral terminals, the area information of the peripheral terminal closer to the terminal to be positioned among the M peripheral terminals may be understood as the closer to the position in the positioning initial message, the higher the distance to the terminal to be positioned, the higher the priority thereof, and the closer to the position in the positioning initial message, the corresponding area information of the peripheral terminal. It can be understood that, in the embodiment of the present application, when the location identifier of the terminal to be located and the area information of the M peripheral terminals are carried in the start message and sent to the location server, the format of the location identifier of the terminal to be located and the area information of the M peripheral terminals also needs to comply with the OMA-TS-ULP V2.0.5 protocol.

For example, after sending the positioning initial message to the positioning server, the terminal to be positioned may stop obtaining the area information of the peripheral terminal, so that it is possible to avoid that the power consumption of the terminal to be positioned is large because the terminal to be positioned always obtains the area information of the peripheral terminal.

S306, the positioning server determines the position of the terminal to be positioned according to the positioning identification of the terminal to be positioned and the area information of the N peripheral terminals.

Taking the area information as the positioning identifier as an example, when the positioning server determines the position of the terminal to be positioned according to the positioning identifier of the terminal to be positioned and the positioning identifiers of the N peripheral terminals, the positioning server searches a database and the like according to the positioning identifier of the terminal to be positioned and the positioning identifiers of the peripheral terminals to obtain effective positions corresponding to the positioning identifiers, and if the positioning identifiers cannot be retrieved in the database, the effective positions cannot be obtained. The positioning server determines the position of the terminal to be positioned from the valid position corresponding to the positioning identifier and the position (if any) obtained from the message by means of an algorithm. It can be understood that the more location data the positioning server algorithm processes, the more accurate the position of the terminal to be positioned is theoretically obtained.

After the position of the terminal to be positioned is determined, whether the position of the terminal to be positioned meets a preset precision condition or not can be judged, and if the position of the terminal to be positioned meets the preset condition, the following steps S307-S308 are directly executed; on the contrary, if it is determined that the position of the terminal to be located does not satisfy the preset condition, the following steps S309-S310 are directly performed:

s307, the positioning server sends a first message to the terminal to be positioned. Wherein the first message comprises the position of the terminal to be positioned.

For example, the first message may be a SUPL END message. The location server will send a SUPLEND message to the terminal to be located, informing the terminal to be located that no further location procedures are to be started and the location session is ended. After receiving the SUPL END message sent by the location server, the terminal to be positioned releases the secure connection and releases all resources related to the session.

And S308, the terminal to be positioned determines the target position of the terminal to be positioned according to the position of the terminal to be positioned.

When the terminal to be positioned receives the first message including the position of the terminal to be positioned, which is calculated by the terminal to be positioned, can be used as the target position of the terminal to be positioned.

It can be seen that, in the embodiment of the application, when the position of the terminal to be positioned is obtained, not only the positioning identifier of the terminal to be positioned is considered, but also the area information of the M peripheral terminals corresponding to the terminal to be positioned is considered, and the target position of the terminal to be positioned is determined jointly according to the positioning identifier of the terminal to be positioned and the area information of the M peripheral terminals, so that the accuracy of the obtained terminal position and the response time for obtaining the target position are improved.

S309, the positioning server sends a first message to the terminal to be positioned. Wherein the first message comprises a reference position of the terminal to be positioned and assistance data.

For example, the first message may be a SUPL POS message.

S310, the terminal to be positioned determines the target position of the terminal to be positioned according to the reference position and the auxiliary data of the terminal to be positioned.

For example, when the target position of the terminal to be positioned is determined according to the first message, the target position of the terminal to be positioned may be determined according to the reference position of the terminal to be positioned and the auxiliary data.

When the terminal to be positioned receives the first message comprising the reference position and the auxiliary data of the terminal to be positioned, the position of the terminal to be positioned, which is calculated by the terminal to be positioned, cannot be used as the target position of the terminal to be positioned.

It can also be seen that, in the embodiment of the present application, when the position of the terminal to be positioned is obtained, not only the positioning identifier of the terminal to be positioned is considered, but also the area information of the M peripheral terminals corresponding to the positioning identifier is considered, and the target position of the terminal to be positioned is determined jointly according to the positioning identifier of the terminal to be positioned and the area information of the M peripheral terminals, so that the accuracy of the obtained terminal position is improved.

The embodiments shown in fig. 2 and fig. 3 describe in detail how to determine the position of the terminal to be positioned when the terminal to be positioned automatically triggers a positioning session. Besides the terminal to be positioned automatically triggering the positioning session, other modules can trigger the positioning session to determine the position of the terminal to be positioned. For example, the other modules may be independently arranged or integrated in the positioning server, please refer to fig. 4, where fig. 4 is a schematic flow chart of another position determining method provided in the embodiment of the present application, and the position determining method may include:

s401, the other modules send MLPSLIR messages to the positioning server.

For example, the MLP SLIR message may include a session ID and a client identifier, where the client identifier is used to indicate an identifier of a terminal that needs to be located, and in this embodiment of the present application, the client identifier is an ID of the terminal to be located.

S402, the positioning server determines a terminal to be positioned according to the client identifier and sends an initial message to the terminal to be positioned.

For example, the initial message may include a session ID, a posmethod, and an SLP mode.

The positioning server sends an initial message to the terminal to be positioned, and the function of the positioning server is as follows: the positioning server is used for starting a positioning session between the terminal to be positioned and the positioning server. After receiving the initial message, the terminal to be positioned establishes data connection with a positioning server; the terminal to be positioned can establish service connection with the M peripheral terminals while establishing data connection, and respectively acquire the area information of each peripheral terminal in the M peripheral terminals based on the established service connection; if the terminal to be positioned has established data connection with the positioning server and has established service connection with the M peripheral terminals, the area information of the M peripheral terminals corresponding to the terminal to be positioned can be directly acquired.

And S403, acquiring the area information of the M corresponding peripheral terminals by the terminal to be positioned.

It should be noted that, in this embodiment of the present application, a method for acquiring, by a terminal to be positioned in S403, region information of M corresponding peripheral terminals is similar to the method for acquiring, by a terminal to be positioned in S201, region information of M corresponding peripheral terminals, which may specifically refer to a description about acquiring, by a terminal to be positioned in S201, region information of M corresponding peripheral terminals, and here, this embodiment is not described in detail again.

S404, the terminal to be positioned sends a positioning initial message to the positioning server.

The initial positioning message comprises a positioning identifier of the terminal to be positioned and area information of M peripheral terminals. As an example, the location initiation message may be a SUPL POS INIT message.

It should be noted that, in this embodiment of the present application, a method for sending, by a terminal to be positioned in S404, a positioning initial message to a positioning server is similar to the method for sending, by a terminal to be positioned in S305, a positioning initial message to a positioning server, where reference may be specifically made to the related description for sending, by a terminal to be positioned in S305, a positioning initial message to a positioning server, and details of this embodiment of the present application are not repeated herein.

S405, the server to be positioned determines the position of the terminal to be positioned according to the positioning identification of the terminal to be positioned and the area information of the M peripheral terminals.

It should be noted that, in this embodiment of the present application, a method for determining a position of a terminal to be positioned by the server to be positioned in S405 according to the positioning identifier of the terminal to be positioned and the area information of the M peripheral terminals is similar to the method for determining the position of the terminal to be positioned by the server to be positioned in S306 according to the positioning identifier of the terminal to be positioned and the area information of the M peripheral terminals, and reference may be specifically made to the related description for determining the position of the terminal to be positioned by the server to be positioned in S306 according to the positioning identifier of the terminal to be positioned and the area information of the M peripheral terminals, where details are not repeated in this embodiment of the present application.

After the position of the terminal to be positioned is determined, whether the position of the terminal to be positioned meets a preset precision condition or not can be judged, and if the position of the terminal to be positioned meets the preset condition, the following S406-S407 is directly executed; on the contrary, if it is determined that the position of the terminal to be positioned does not satisfy the preset condition, the following steps S408-S409 are directly executed:

s406, the positioning server sends a first message to the terminal to be positioned. Wherein the first message comprises the position of the terminal to be positioned.

For example, the first message may be a SUPL END message.

S407, the terminal to be positioned determines the target position of the terminal to be positioned according to the position of the terminal to be positioned.

It can be seen that, in the embodiment of the application, when the position of the terminal to be positioned is obtained, not only the positioning identifier of the terminal to be positioned is considered, but also the area information of the M peripheral terminals corresponding to the positioning identifier is considered, and the target position of the terminal to be positioned is determined together according to the positioning identifier of the terminal to be positioned and the area information of the M peripheral terminals, so that the accuracy of the obtained terminal position is improved.
