Background technique

With the advent of the intelligent era, the configuration of terminals is becoming more and more powerful, and the applications on the terminals are also increasing. At present, most applications need to obtain the location information of the terminal in order to provide users with more humanized services. Therefore, how to determine the location (ie, positioning) of the terminal has become an important research problem.

Assisted Global Navigation Satellite System (A-GNSS) is a widely used positioning method. When using the auxiliary GNSS technology to locate the terminal, it needs to be based on the auxiliary positioning data. Therefore, the auxiliary positioning data plays an important role in the positioning process of the terminal, and directly affects the efficiency and accuracy of the positioning. However, with the A-GNSS positioning technology, the terminal needs to establish a network connection with the A-GNSS server, and obtain auxiliary positioning data from the A-GNSS server according to the established connection, thereby increasing the network load.

In the case of the side configuration, the auxiliary positioning data in the shared terminal is updated to realize the sharing of the auxiliary positioning data between different terminals. Compared with the prior art, the terminal needs to communicate with the A-GNSS server to obtain the auxiliary positioning data.

Moreover, the terms "comprises" and "comprising" and "comprising" are intended to cover a non-exclusive inclusion. For example, a process, method, system, product, or device that comprises a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units not listed, or, optionally, Other steps or units inherent to these processes, methods, products or equipment.

Based on the existing A-GNSS positioning technology, the terminal needs to establish a network connection with the A-GNSS server to obtain the auxiliary positioning data, thereby increasing the network burden. The embodiment of the present application proposes to share between multiple terminals. A method for assisting in locating data, so that the terminal that needs to be located does not need to obtain auxiliary positioning data from the A-GNSS server, thereby effectively reducing the network burden.

In order to realize the sharing of the auxiliary positioning data between the multiple terminals, the embodiment of the present application realizes the sharing of the auxiliary positioning data between the terminals by extending the existing short-distance communication protocol. Specifically, the existing short-range communication protocol may not be affected. Based on the original communication protocol function of the probe request frame and the probe response frame (Probe Response), the data format of the existing probe request frame and the probe response frame is expanded, and then the extended probe request frame is extended. And the probe response frame is used to realize the sharing of the auxiliary positioning data, and in this way, the auxiliary positioning data can be shared without establishing a network connection between the terminals.

The probe request frame and the probe response frame involved in the sharing method of the embodiment of the present application refer to the extended probe request frame and the probe response frame.

It should be noted that the short-distance communication protocol may be a Wireless Fidelity (Wi-Fi) 802.11 communication protocol or a Bluetooth communication protocol, and other various short-range communication protocols, which are not limited.

The embodiment of the present application is only described by taking an example that the probe request frame and the probe response frame are extended according to the probe request frame and the probe response frame in the Wi-Fi 802.11 communication protocol.

In order to more clearly introduce the probe request frame and the probe response frame involved in the sharing method of the present application, the probe request frame and the probe response frame in the Wi-Fi 802.11 communication protocol are first introduced below.

FIG. 1a is a schematic structural diagram of a probe request frame in a Wi-Fi 802.11 communication protocol. As shown in FIG. 1a, the probe request frame in the Wi-Fi 802.11 communication protocol includes the following three parts: a header (Header), Frame Body, Frame Check Sequence (FCS). The frame header includes a Frame Control structure, a Duration/ID, an Address Field, and a Sequence Control.

FIG. 1b is a schematic structural diagram of a probe response frame in a Wi-Fi 802.11 communication protocol. As shown in FIG. 1b, the probe response frame in the Wi-Fi 802.11 communication protocol also includes the following three parts: a frame header, a frame body, and an FCS. The frame header includes a frame control structure, a duration/identity, an address field, and a sequence control field.

There is a difference between the content of the Frame Body contained in the probe request frame and the probe response frame in the Wi-Fi 802.11 communication protocol. Specifically, the Frame Body of the probe request frame may include a Service Set Identity (SSID), a Supported Rate, and an Extended Supported Rate. The Frame Body of the probe response frame includes various contents such as an SSID, an extended support rate, a Robust Security Network (RSN), and the like.

Based on the structure of the probe request frame and the probe response frame in the Wi-Fi 802.11 communication protocol, the probe request frame involved in the sharing method of the present application may be a request added in the probe request frame in the Wi-Fi 802.11 communication protocol. After the information unit is obtained, the request information unit is used to carry the request information of the auxiliary positioning data. As specified in the Wi-Fi 802.11 communication protocol, the frame body of the probe request frame may be extended. Therefore, the request information unit in the present application may be located between the frame header of the probe request frame and the FCS, that is, the frame body, thereby minimizing Changes to existing communication protocols. In the present application, the specific location of the request information element in the frame body is not limited. In the case where the probe request frame is as shown in FIG. 1a, the request information unit may be located in any of the following areas:

(1) between the frame header and the SSID;

(2) between the SSID and the support rate;

(3) between the support rate and the extended support rate;

(4) Extended support between the rate and the FCS.

For example, the request information unit is located between the extended support rate and the FCS, as shown in FIG. 1c, which is a schematic structural diagram of the probe request frame in this application. The probe response frame involved in the present application may be obtained by adding a response information unit to the probe response frame in the Wi-Fi 802.11 communication protocol, and the response information unit is configured to carry the response information of the auxiliary positioning data. Due to Wi-Fi 802.11 The communication protocol stipulates that the frame body of the probe response frame can be extended. Therefore, the response information unit in the present application can be located between the frame header of the probe response frame and the FCS, that is, the frame body, thereby minimizing the existing communication protocol. change. In this application, the specific location of the response information unit in the frame body is not limited. For example, the response information unit may be located between the robust security network and the FCS, as shown in FIG. 1d, which is a schematic structural diagram of the probe response frame in this application. . Since the content of the frame body in the probe response frame is large, the position of the response information unit is not exemplified here.

It should be noted that the method for sharing the auxiliary positioning data between the multiple terminals in the present application may be applicable to the terminal positioning scenario described above, and may also be applicable to other scenarios involving the terminal acquiring the auxiliary positioning data. Make a limit.

FIG. 2 is a schematic diagram of a system architecture applicable to the present application. The system architecture may include multiple terminals, and one or more terminals to be shared and one or more shared terminals may exist in multiple terminals. In FIG. 2, only one terminal to be shared and three shared terminals are used. The example is explained. As shown in FIG. 2, the system architecture includes a to-be-shared terminal 201, a first shared terminal 2021, a second shared terminal 2022, and a third shared terminal 2023. The to-be-shared terminal 201 sends a probe request frame, and after receiving the probe request frame, the first shared terminal 2021, the second shared terminal 2022, and the third shared terminal 2023 may return a probe response frame to the to-be-shared terminal 201, and the probe response frame includes the assistance. The response information of the positioning data, that is, the communication between the to-be-shared terminal 201 and the first shared terminal 2021, the second shared terminal 2022, and the third shared terminal 2023 can be communicated through the probe request frame and the probe response frame.

In this application, the terminal to be shared refers to a terminal that needs to obtain auxiliary positioning data, and the shared terminal is a terminal that sends auxiliary positioning data to the terminal to be shared. In different scenarios, the terminal to be shared can also be a shared terminal, and the shared terminal can also be a terminal to be shared. For example, in the architecture shown in FIG. 1, at a certain moment, if the first sharing terminal 2021 determines that the auxiliary positioning data needs to be acquired, the sharing terminal 201, the second sharing terminal 2022, and the third sharing terminal 2023 do not need the auxiliary positioning data. The first shared terminal 2021 can be a shared terminal, and the shared terminal 201, the second shared terminal 2022, and the third shared terminal 2023 can become shared terminals.

In this application, the terminal to be shared and the shared terminal refer to the terminal that can support the A-GNSS positioning function. The terminal may be a wired terminal or a wireless terminal, and the wireless terminal may be a handheld device with a wireless connection function or another processing device connected to the wireless modem, and the mobile terminal communicates with one or more core networks via the wireless access network. . For example, the wireless terminal can be a mobile phone, a tablet, a personal digital assistant (PDA), a mobile Internet device (MID), a wearable device, and an e-book reader (e-book). Reader) and so on. As another example, the wireless terminal can also be a portable, pocket, handheld, computer built-in or in-vehicle mobile device.

Some technical solutions of the present application may be specifically implemented based on the system architecture shown in FIG. 2 or its variant architecture.

FIG. 3 is a schematic flowchart of a method for sharing auxiliary positioning data according to Embodiment 1 of the present application. As shown in FIG. 3, the method includes:

Step 301: The to-be-shared terminal sends a probe request frame, where the probe request frame includes request information for assisting positioning data.

Step 302: The sharing terminal receives a probe request frame sent by the terminal to be shared.

Step 303: The sharing terminal sends a probe response frame to the to-be-shared terminal according to the request information of the auxiliary location data in the probe request frame, where the probe response frame includes response information of the auxiliary location data of the shared terminal.

Step 304: The to-be-shared terminal receives a probe response frame that is sent by the at least one shared terminal according to the request information of the auxiliary positioning data in the probe request frame.

Step 305: The to-be-shared terminal updates the auxiliary positioning data in the to-be-shared terminal according to the response information of the auxiliary positioning data of the at least one shared terminal.

In the above process, step 301, step 304, and step 305 may be performed by the terminal to be shared 201 shown in FIG. 2, and step 302 and step 303 may be performed by the first sharing terminal 2021 and the second sharing terminal 2022 shown in FIG. 2. Any of the third sharing terminals 2023 is executed.

In this application, the to-be-shared terminal sends the request information of the auxiliary positioning data through the probe request frame, and receives the response information of the auxiliary positioning data of the at least one shared terminal by detecting the response frame, so that the terminal to be shared can be not connected to the network, and Increase the network side configuration, treat the total The auxiliary positioning data in the terminal is updated, that is, the auxiliary positioning data sharing between different terminals is realized, and the method is similar to the method in the prior art that the terminal needs to communicate with the A-GNSS server to obtain the auxiliary positioning data. The network load is reduced, which is more convenient and effective; and the communication between the shared terminal and the shared terminal is realized by the probe request frame and the probe response frame, and the network connection is not required to be established between the shared terminal and the shared terminal, thereby further improving communication efficiency. It is beneficial to improve the positioning speed based on the auxiliary positioning data.

In this application, the request information of the auxiliary positioning data may include the request identifier of the auxiliary positioning data and the time information of the auxiliary positioning data of the terminal to be shared. Specifically, the request information unit in the probe request frame may be divided into two data bits: AGNSS DATA REQUEST and CURRENT DATA TIMESTSMP, AGNSS DATA REQUEST is used to carry the request identifier of the auxiliary positioning data, and CURRENT DATA TIMESTSMP is used to carry the time information of the auxiliary positioning data of the terminal to be shared, as shown in FIG. 1c.

The request identifier of the auxiliary positioning data is used to indicate whether the probe request frame requests the auxiliary positioning data. For example, the first setting, if the probe request frame requests the assisted positioning data, the request identifier of the auxiliary positioning data may be “1” or “ TRUE", at this time, the request identifier of the auxiliary positioning data is a valid request identifier; if the probe request frame does not request the auxiliary positioning data, the request identifier of the auxiliary positioning data may be "0" or "FALSE", and the request identifier of the auxiliary positioning data at this time Identifies the invalid request. Or the second setting, if the probe request frame requests the auxiliary positioning data, the request identifier of the auxiliary positioning data may be “0” or “FALSE”, and the request identifier of the auxiliary positioning data is a valid request identifier; if the probe request frame If the auxiliary positioning data is not requested, the request identifier of the auxiliary positioning data may be “1” or “TRUE”, and the request identifier of the auxiliary positioning data is an invalid request identifier. In the present application, only the first setting is taken as an example for explanation.

The time information of the auxiliary positioning data of the terminal to be shared is used to indicate the time of the auxiliary positioning data of the terminal to be shared (specifically, the acquisition time of the auxiliary positioning data of the terminal to be shared), for example, the auxiliary positioning data of the terminal to be shared is x years. When the x-day x-day x is obtained, the time information may be x-year x-month x-day x, and the time information of the auxiliary positioning data of the terminal to be shared is the effective time information. If the auxiliary positioning data does not exist in the terminal to be shared, the time information can be set to 0, and the time is to be shared. The time information of the auxiliary positioning data of the terminal is invalid time information.

The manner in which the request identifier and the time information are expressed may be set by a person skilled in the art according to experience, and the above is merely an example.

In step 301, taking the location scenario as an example, if the terminal to be shared does not need to be located, the request identifier of the auxiliary positioning data in the probe request frame may be set as an invalid request identifier, and according to the existing short-range communication protocol, according to the existing short-distance communication protocol. The fixed-cycle broadcast probe request frame; after the terminal to be shared determines that the location needs to be located, the request identifier of the auxiliary positioning data in the probe request frame may be set as a valid request identifier, and the probe request frame may be sent, and the specific sending manner may also be broadcast. The time information of the auxiliary positioning data of the terminal to be shared in the probe request frame is changed only according to the update situation of the auxiliary positioning data of the terminal to be shared in the probe request frame in the case that the positioning and the positioning are not required.

In step 302, the sharing terminal receives the probe request frame sent by the terminal to be shared, and parses the request identifier of the auxiliary positioning data in the probe request frame and the time information of the auxiliary positioning data of the terminal to be shared.

In step 303, if the sharing terminal determines that the request identifier of the auxiliary positioning data is an invalid request identifier, the probe request frame may be processed according to the manner in the existing short-range communication protocol. Specifically, the probe response frame or feedback may not be fed back. The probe response frame does not include the auxiliary positioning data of the shared terminal, thereby effectively saving transmission resources.

If the request identifier of the shared positioning data is determined to be a valid request identifier, the shared positioning data of the shared terminal may be determined according to the time information of the auxiliary positioning data of the terminal to be shared and the time information of the auxiliary positioning data of the shared terminal. If it is valid, the auxiliary positioning data of the shared terminal is sent to the terminal to be shared by the probe response frame. If invalid, the probe request frame may be processed according to the manner in the existing short-range communication protocol. Specifically, the feedback request may not be fed back. The probe response frame or the feedback probe response frame does not include the auxiliary positioning data of the shared terminal, thereby effectively saving transmission resources.

The specific manner of determining whether the auxiliary positioning data of the shared terminal is valid is that the sharing terminal first determines whether the time information of the auxiliary positioning data of the terminal to be shared is valid time information:

(1) The time information of the auxiliary positioning data of the terminal to be shared is invalid time information, and the sharing terminal Determining, according to the time information of the auxiliary positioning data of the shared terminal, whether the interval between the time of the auxiliary positioning data of the shared terminal and the current time is less than or equal to the first threshold, and if yes, determining that the auxiliary positioning data of the sharing terminal is valid; And determining that the auxiliary positioning data of the shared terminal is invalid. The first threshold can be set empirically by those skilled in the art, for example, can be set to 2h.

For example, the time information of the auxiliary positioning data of the shared terminal is 8:00 on October 11, 2016, and the shared terminal determines the time information of the auxiliary positioning data of the terminal to be shared as the invalid time information, and then determines the auxiliary positioning data of the shared terminal. The interval between the time (8:00 on October 11, 2016) and the current time (9:00 on October 11, 2016) is 1h, which is less than the first threshold (2h), so it can be determined that the auxiliary positioning data of the shared terminal is valid. .

That is to say, since the acquisition time of the auxiliary positioning data is smaller than the current time interval, the utilization value is larger, and the positioning accuracy and accuracy are higher when the positioning is performed according to the auxiliary positioning data, so if the terminal to be shared is in the terminal If there is no auxiliary positioning data, the shared terminal needs to locate the auxiliary positioning data when the time for determining its own auxiliary positioning data is relatively new (that is, the auxiliary positioning data is recently acquired and the current time interval is small). The probe response frame is sent to the to-be-shared terminal, so that the auxiliary positioning data received by the terminal to be shared is the auxiliary positioning data with large utilization value, which effectively avoids transmitting the non-utilization value or using the auxiliary positioning data with less value to waste resources. .

If the sharing terminal determines that its own auxiliary positioning data is older (that is, the auxiliary positioning data is acquired a long time ago, and the current time interval is larger), the feedback response frame may not be fed back or the feedback detection response frame is not included. The auxiliary positioning data of the shared terminal saves transmission resources.

(2) The time information of the auxiliary positioning data of the shared terminal is the effective time information, and the sharing terminal determines, according to the time information of the auxiliary positioning data of the shared terminal and the time information of the auxiliary positioning data of the terminal to be shared, Whether the time of the auxiliary positioning data of the shared terminal is later than the time of the auxiliary positioning data of the terminal to be shared, that is, whether the interval between the time of the auxiliary positioning data of the shared terminal and the current time is smaller than the auxiliary positioning of the terminal to be shared. The interval between the time of the data and the current time, if yes, determining that the auxiliary positioning data of the shared terminal is valid, and if not, determining that the auxiliary positioning data of the shared terminal is invalid.

For example, the time information of the auxiliary terminal's auxiliary positioning data is 8:00 on October 11, 2016. When the time information of the auxiliary positioning data of the terminal to be shared is determined as the effective time information (the time information of the auxiliary positioning data of the terminal to be shared is 7:00 on October 11, 2016), the auxiliary positioning data of the shared terminal is determined. The time (8:00 on October 11, 2016) is later than the time of the auxiliary positioning data of the terminal to be shared (7:00 on October 11, 2016), so it can be determined that the auxiliary positioning data of the shared terminal is valid.

That is to say, if there is auxiliary positioning data in the terminal to be shared, the time at which the shared terminal needs to determine its own auxiliary positioning data is later than the auxiliary positioning data of the terminal to be shared, that is, the auxiliary positioning data of the sharing terminal is newer. When the utilization value is greater than the utilization value of the auxiliary positioning data of the terminal to be shared, the auxiliary positioning data can be sent to the to-be-shared terminal through the probe response frame, thereby ensuring that the auxiliary positioning data received by the terminal to be shared is The use value of the auxiliary positioning data itself is large. If the time for the shared terminal to determine its own auxiliary positioning data is earlier than the time of the auxiliary positioning data of the terminal to be shared, that is, the utilization value is smaller than the utilization value of the auxiliary positioning data of the terminal to be shared. Then, the auxiliary positioning data is not transmitted to the terminal to be shared, so that the transmission resource is saved, and the auxiliary positioning data is not received by the terminal to be shared, and the processing burden of the terminal to be shared is reduced.

In step 304, the to-be-shared terminal receives the probe response frame sent by the at least one shared terminal. Specifically, if only one shared terminal feeds the probe response frame around the terminal to be shared, the to-be-shared terminal only receives the probe sent by the shared terminal. In response to the frame, if there are multiple shared terminal feedback probe response frames around the shared terminal, the to-be-shared terminal may receive the probe response frames sent by multiple shared terminals.

In this application, in order to further improve the speed of updating the auxiliary positioning data of the terminal to be shared, the to-be-shared terminal may start a timer after determining that the probe needs to be located and sent the probe response frame, and determine that the timer reaches the first time threshold, and then according to the receiving The response information of the auxiliary positioning data sent by the at least one shared terminal is updated to the auxiliary positioning data of the shared terminal. The first time threshold can be set empirically by those skilled in the art. That is, the to-be-shared terminal may update the auxiliary positioning data of the shared terminal according to the response information of the auxiliary positioning data sent by the shared terminal received within the set duration after transmitting the probe response frame, thereby avoiding feedback feedback of some shared terminals. The frame takes longer and the update speed is reduced.

Considering that there may be no shared terminal around the terminal to be shared, or there is a shared terminal, but the auxiliary positioning data of the shared terminal is invalid, so that the terminal to be shared may determine that the timer has not received the shared terminal after receiving the first time threshold. Auxiliary positioning data response information. In this case, the to-be-shared terminal can acquire the auxiliary positioning data from the A-GNSS server in an existing manner.

In this application, the response information of the auxiliary positioning data of the sharing terminal may include the auxiliary positioning data of the sharing terminal and the time information of the auxiliary positioning data of the sharing terminal. Specifically, the response information unit in the probe response frame may also be divided into two data bits, which are respectively used to carry the auxiliary positioning data of the shared terminal and the time information of the auxiliary positioning data of the shared terminal, as shown in FIG. 1d.

The time information of the auxiliary positioning data of the shared terminal is used to indicate the time of the auxiliary positioning data of the shared terminal (specifically, the acquisition time of the auxiliary positioning data of the shared terminal), and the specific representation manner may refer to the to-be-included in the foregoing probe request frame. An introduction to the time information of the auxiliary terminal's auxiliary positioning data.

In step 305, the to-be-shared terminal determines the time information with the smallest time interval from the current time interval according to the time information of the auxiliary positioning data of the multiple shared terminals, and determines the auxiliary positioning data corresponding to the time information with the smallest current time interval as Auxiliary positioning data after the shared terminal is updated.

Specifically, if there is auxiliary positioning data in the to-be-shared terminal, the previous auxiliary positioning data may be deleted, and the auxiliary positioning data corresponding to the time information with the smallest current time interval is determined as the auxiliary positioning after the terminal to be shared is updated. Data; if there is no auxiliary positioning data in the terminal to be shared, the auxiliary positioning data corresponding to the time information with the smallest current time interval may be directly determined as the auxiliary positioning data after the terminal to be shared is updated; correspondingly, the terminal to be shared next time When it is determined that the positioning is required, the time information of the auxiliary positioning data of the terminal to be shared in the probe request frame sent by the probe request frame is determined according to the time of the updated auxiliary positioning data.

For example, if the shared terminal receives the response information of the auxiliary positioning data sent by the two shared terminals (the shared terminal a and the shared terminal), the time for the auxiliary positioning data of the shared terminal a is 8:30 on October 11, 2016. The time for sharing the auxiliary positioning data of the terminal b is 8:40 on October 11, 2016, and the current time is 9:00 on October 11, 2016. After the shared terminal is judged, the shared terminal with a new time can be added. The auxiliary positioning data is determined as the updated auxiliary positioning data.

Subsequently, the to-be-shared terminal may send the updated auxiliary positioning data to the GNSS engine of the terminal to be shared for subsequent positioning.

In order to more clearly introduce the overall flow of the method for sharing the auxiliary positioning data in the present application, further explanation will be given below with reference to FIG. 4. FIG. 4 is a schematic overall flow chart of a method for sharing auxiliary positioning data in the present application, as shown in FIG. 4, including:

Step 403, the sharing terminal determines whether the request identifier of the auxiliary positioning data is a valid request identifier, and if so, step 404 is performed, and if no, step 409 is performed;

Step 404, the sharing terminal determines whether the time information of the auxiliary positioning data of the terminal to be shared is valid time information, and if so, step 405 is performed, and if not, step 406 is performed;

Step 405, the sharing terminal determines whether the time of the auxiliary positioning data of the shared terminal is later than the time of the auxiliary positioning data of the terminal to be shared, if yes, step 407 is performed, and if not, step 409 is performed;

Step 406, the sharing terminal determines whether the interval between the time of the auxiliary positioning data of the shared terminal and the current time is less than or equal to the first threshold, and if so, step 407 is performed, and if not, step 409 is performed;

Step 407: The sharing terminal sends a probe response frame to the to-be-shared terminal, where the response response frame includes response information of the auxiliary positioning data.

Step 408: The to-be-shared terminal receives the probe response frame sent by the at least one shared terminal, and updates the auxiliary positioning data in the shared terminal according to the response information of the auxiliary positioning data of the at least one shared terminal. Subsequently, the to-be-shared terminal may update. The subsequent auxiliary positioning data is sent to the GNSS engine of the terminal to be shared, so as to facilitate subsequent positioning of the shared terminal;

Step 409: The shared terminal processes the received probe request frame according to the manner in the existing short-range communication protocol.

It should be noted that the numbering of each step described above is merely an exemplary description of an execution process. There is no clear and specific order for each step.

If the network side configuration is not required, the auxiliary positioning data in the shared terminal is updated to implement the sharing of the auxiliary positioning data between different terminals, and the terminal needs to communicate with the A-GNSS server to obtain the communication in the prior art.
