Description

Terminal positioning method and device

The present application claims priority to Chinese Patent Application No. 201410090598.8, entitled "A Terminal Positioning Method and Apparatus", filed on March 12, 2014, the entire contents of which is incorporated herein by reference. .

Technical field

The present invention relates to the field of communications technologies, and in particular, to a terminal positioning method and device.

Background technique

In the existing wireless mobile communication system, the mobile positioning service is a service carried out using the location of a user equipment (User Equipment, UE; also referred to as a terminal), such as emergency rescue.

Currently, there are two types of implementation methods for terminal positioning: control plane positioning and user plane positioning (Secure User-Plane Location).

The control plane is mainly used for signaling related information transmission, that is, the positioning data is transmitted through the control plane signaling; the user plane positioning is based on the Open Mobile Alliance Secure User Plane Location (Open Mobile Alliance Secure User Plane Location, OMA SUPL) protocol, the transmission of positioning related information on the user side, the related signaling of the protocol and the specific positioning related information are not visible on the access network side, because the data is transmitted through a dedicated radio bearer (Dedicated Radio Bearer) , DRB) to transmit, not through signaling.

At present, the main methods of control plane positioning are as follows:

The first type locates the terminal based on the CELL Identity (CELL ID) of the terminal.

The location of the UE is estimated based on information of its serving base station and cell, and the information of the serving base station and the cell can be obtained by call, location area update, cell update, URA update, or routing area update. The location information of the coverage area of the serving cell may be represented as a cell identifier of the serving cell, a service area identifier, a geographic coordinate related to the serving cell, and the like. The positioning accuracy of this method depends on the radius of the cell, which is generally several hundred meters to several kilometers.

The second type is based on the terminal service cell identifier (CELL ID), the timing advance (Timing Advance, TA), and the incoming wave direction (Angele of Arrival (AOA) positioning terminal, referred to as CELL ID+TA+AOA.

The positioning method considers the timing advance and the direction of the incoming wave on the basis of the first positioning mode, thereby achieving more accurate positioning purposes, and the general positioning accuracy is 50-150 meters.

The third method, the Observed Time Difference of Arrival (OTDOA) positioning method, is based on the time difference of the arrival of the reference signals of different cells received by the terminal.

The positioning accuracy of this method is generally 10-200 meters.

The fourth method, the uplink time difference of arrival (U-TDOA) positioning method is a time difference positioning terminal based on the arrival of the transmission signal of the terminal obtained by the different location measurement unit (LMU) measurement. .

The fifth, based on the network assisted Global Navigation Satellite System (A-GNSS) positioning terminal.

The positioning method is a technology for positioning a terminal by combining network base station information and satellite navigation information, and uses a satellite navigation system and a base station in the mobile communication system to improve the positioning performance of the terminal. In this method, at least four satellites are required to implement the positioning. accurate locating. In the current use of satellite positioning, the accuracy can reach about 10 meters. However, if the terminal is in an indoor or high-rise area and cannot receive navigation satellite signals, the positioning accuracy may be several hundred meters or more, and it may not be possible to locate at all.

In summary, in the existing wireless mobile communication system, the positioning accuracy of the control plane positioning in some scenarios is poor, especially in the case that A-GNSS positioning cannot be performed, other positioning methods cannot achieve accurate positioning, indoor positioning. The accuracy is 50-150 meters, which can not meet the requirements of precise positioning of the terminal caused by the continuous optimization of the wireless mobile communication system. It is necessary to further improve the control plane positioning accuracy, so that the network side can optimize resources according to the location of the terminal or select appropriate characteristics. .

detailed description

The present invention will be further described in detail with reference to the accompanying drawings, in which . All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

In order to improve the accuracy of the control plane positioning terminal, the network side performs resource optimization according to the location of the terminal or selects a suitable feature, for example, the network side determines whether the terminal uses a device to device (D2D) communication function, etc., and the embodiment of the present invention A terminal positioning method and device are provided.

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

In the embodiment of the present invention, the terminal locating device, such as the location server, triggers the terminal to enable the wireless local area network (WLAN) positioning function according to the location or environment of the terminal, and performs a WLAN access point (AP). The measurement result is obtained by the terminal, and the positioning server performs terminal position calculation or correction according to the measurement result of the WLAN AP reported by the terminal, so as to achieve accurate positioning.

As shown in FIG. 1 , in the first embodiment of the present invention, a positioning server on the network side, such as an Evolved Serving Mobile Location Center (E-SMLC), is used as an execution subject to implement detailed control plane positioning. The method flow is as follows:

Step 101: Send, according to location related information of the terminal and distribution information of the WLAN AP, first signaling for instructing the terminal to enable WLAN positioning.

Preferably, before transmitting the first signaling for instructing the terminal to enable WLAN positioning, determining, according to the capability information reported by the terminal, that the terminal can perform WLAN AP detection, that is, determining that the terminal has WLAN positioning capability.

Preferably, the location related information of the terminal is any one of the following three types:

The location information of the serving cell where the terminal is located, the location information of the historical location of the terminal, and the location information that the terminal uses to locate other locations than the WLAN positioning.

In practical applications, the location-related information of the terminal is not limited to the above three types, and can be roughly indicated. The location information of the location of the terminal can be used as the location related information of the terminal.

Preferably, the first signaling is sent when the number of WLAN APs whose distance from the terminal is within a preset range is not less than a set value, according to the location-related information of the terminal and the distribution information of the WLAN AP. The set value is the minimum number of WLAN APs that can be used to locate the terminal.

Specifically, the location server of the network side pre-stores a distribution map of the WLAN AP, and the location server delimits a preset range that is less than a predetermined value from the terminal according to the location-related information of the terminal, and determines the WLAN AP included in the predetermined range. Number.

In a specific implementation, before the first signaling for instructing the terminal to enable the WLAN positioning, the terminal is initially positioned by using another positioning manner other than the WLAN positioning mode; and determining the measurement value for calculating the initial positioning position. Below the preset threshold, or to determine that the initial positioning of the terminal fails. That is, before the first signaling for instructing the terminal to enable WLAN positioning, the positioning may be initially performed by using a positioning manner other than the WLAN positioning mode, and when one of the following two conditions is met, Sending a first signaling for instructing the terminal to enable WLAN positioning:

The first case: the measured value of the position for calculating the initial positioning is lower than a preset threshold;

The second case: the initial positioning of the terminal fails.

In the initial positioning of the terminal, any one of the control plane positioning modes in the existing wireless mobile communication system can be used.

Specifically, the manner of initially positioning the terminal includes any one of the following ways:

Positioning the terminal based on the serving cell identity of the terminal;

Determining the terminal based on the identity of the serving cell of the terminal, the timing advance, and the direction of the incoming wave;

And positioning the terminal based on a time difference of arrival of reference signals of different cells received by the terminal;

Positioning the terminal based on a time difference of arrival of a transmission signal of the terminal obtained by the different positioning measurement unit LMU measurement;

For example, if the initial positioning is performed by using network-assisted global satellite navigation, when the number of detected satellites is less than four, that is, the number of measured satellites is less than a preset threshold, the initial positioning identification is determined, and WLAN positioning needs to be initiated; or , the received signal strength indication of the detected satellite (Received If the Signal Strength Indication (RSSI) is lower than the preset threshold, it is determined that the satellite signal quality is very poor and the WLAN positioning needs to be started.

In the embodiment of the present invention, the first signaling may have multiple implementation manners according to different information carried, including but not limited to the following implementation manners:

In a mode, the first signaling carries indication information that instructs the terminal to initiate a WLAN AP search and measure signal strength information and/or signal quality information;

In the mode b, the first signaling carries the identification number of the WLAN AP;

In the mode c, the first signaling carries the identification number of the WLAN AP and an index number;

In the mode d, the first signaling carries a Service Set Identifier (SSID) of the WLAN AP.

In a specific implementation, the first signaling further carries a measurement quantity that needs to be measured by the terminal, and the measurement quantity that is required to be measured by the terminal is at least signal strength information and/or signal quality information. If the first signaling does not carry the measurement quantity that needs to be reported by the terminal, the default measurement quantity of the terminal is the received signal strength indication.

Specifically, the signal strength information includes any one or more of a received signal strength indicator, a Received Channel Power Indicator (RCPI), and the like, and the signal quality information includes an input frame signal to noise ratio (Input Ratio of signal to noise). , RSNI) and so on.

Preferably, the identification number of the WLAN AP is a Media Access Control (MAC) address of the WLAN AP, which is also called a physical address.

Step 102: Receive second signaling returned by the terminal, where the second signaling carries at least signal strength information and/or signal quality information of the WLAN AP detected by the terminal and identifier information of the corresponding WLAN AP.

The WLAN APs detected by the terminal are not completely the same according to the information carried in the first signaling, and the second signaling received by the positioning server is not completely the same.

The identification information of the WLAN AP may be the identification number or the index number of the WLAN AP. In actual applications, the identification information of the WLAN AP is not limited to the two types. For other information that can uniquely determine the WLAN AP, the information may also be used as the WLAN AP. Identification information.

Corresponding to different implementation manners of the first signaling, the second signaling has one of the following specific implementation manners:

The first type, corresponding to the implementation manner a of the first signaling, if the first signaling includes indication information indicating that the terminal starts the WLAN AP search and measures the signal strength information and/or the signal quality information, the second signaling carries The identification information of the WLAN AP detected by the terminal and the corresponding signal strength information and/or signal quality information.

The second type, corresponding to the implementation manner b of the first signaling, if the first signaling includes the identification number of the WLAN AP, the second signaling carries the identifier information of the WLAN AP in the terminal detection and the first signaling. The signal strength information and/or signal quality information of the corresponding WLAN AP and the identification number of the corresponding WLAN AP.

The third type, corresponding to the implementation manner c of the first signaling, if the first signaling includes the identification number and the index number of the WLAN AP, the second signaling carries the terminal detection and the WLAN AP in the first signaling. The signal strength information and/or signal quality information of the WLAN AP corresponding to the identification number, and the corresponding index number.

The fourth type, corresponding to the implementation manner d of the first signaling, if the first signaling includes the service set identifier SSID of the WLAN AP, the second signaling carries the SSID in the first signaling detected by the terminal. The identification information of the WLAN AP and the corresponding signal strength information and/or signal quality information.

Step 103: Locating the terminal according to the signal strength information and/or the signal quality information of the WLAN AP and the identifier information of the corresponding WLAN AP.

Specifically, if the control plane positioning manner of the wireless mobile communication system other than the WLAN positioning mode is used before or at the same time to perform WLAN positioning, the signal strength information and/or the signal quality information of the WLAN AP and the information may be combined. The positioning information of the corresponding WLAN AP and the control plane positioning manner of the wireless mobile communication system other than the WLAN positioning mode are used to determine the precise positioning position of the terminal.

For example, after the location of the area in which the terminal is located is determined by using the control plane positioning mode of the wireless mobile communication system other than the WLAN positioning mode, the signal strength information of the WLAN AP and the identifier of the corresponding WLAN AP are further determined. Information, precise determination within the region The terminal can narrow the search range of the precise positioning and further ensure the accuracy of the positioning.

The terminal is located according to the signal strength information and/or the signal quality information of the WLAN AP and the identifier information of the corresponding WLAN AP. The following two processing modes are specifically implemented:

The first is a three-point positioning method.

The location of the WLAN AP is known. The terminal can compare the original signal strength by detecting the wireless signal strength RSSI received by the device, and estimate the distance from the terminal to the AP through the transmission model. A plurality of WLAN APs are usually installed indoors. Generally, the coordinates of each WLAN AP are known, and the distance from the terminal to each AP can be obtained by calculation, that is, the coordinate position of the terminal can be calculated by using the three-point positioning method.

The second type is the fingerprint positioning method, which is mainly divided into two processes: the sampling process and the positioning process.

The sampling process is specifically as follows: the system uniformly selects several points in the environment as reference points, and samples the RSSI/RCPI/RSNI values of the WLAN APs that can be measured at these reference points, and the distribution characteristics of these measured values are combined with the reference points. The coordinates are stored in the fingerprint database. The sampling process depends on the algorithm implementation. For example, the average value is used as the reference point feature, or the measurement value distribution is regarded as a logarithmic distribution, or the measurement value distribution of each WLAN AP is associated as a multi-Gaussian distribution.

The positioning process is specifically as follows: the mobile terminal turns on the Wireless Fidelity (Wi-Fi) scan, and the scanned result is put into the fingerprint database for matching, and a certain number of points are selected to estimate the current location of the terminal.

Preferably, in a Long Term Evolution (LTE) system, the first signaling is LTE positioning protocol (LPP) signaling.

As shown in FIG. 2, in the second embodiment of the present invention, the detailed method for performing control plane positioning by using the terminal side as an execution body is as follows:

Step 201: Receive first signaling sent by the network side to instruct the terminal to enable WLAN positioning.

Preferably, the terminal reports capability information capable of performing WLAN AP detection to the network side before receiving the first signaling sent by the network side to instruct the terminal to enable WLAN positioning.

In the embodiment of the present invention, the first signaling may have multiple implementation manners according to different information carried, including but not limited to the following implementation manners:

In a mode, the first signaling carries the indication that the terminal initiates the WLAN AP search and measures the signal strength signal. Information indicating information and/or signal quality information;

In the mode b, the first signaling carries the identification number of the WLAN AP;

In the mode c, the first signaling carries the identification number of the WLAN AP and an index number;

In the mode d, the first signaling carries the service set identifier SSID of the WLAN AP.

Step 202: Acquire the detected signal strength information and/or signal quality information of the WLAN AP and the identifier information of the corresponding WLAN AP, and send the signal strength information and/or signal quality information and the corresponding WLAN AP to the network side. The second signaling of the identification information is located by the network side according to the signal strength information and/or the signal quality information and the identifier information of the corresponding WLAN AP.

In the embodiment of the present invention, according to different information carried in the first signaling, the WLAN APs detected by the terminal are not completely the same, and the second signaling received by the positioning server is not completely the same. Specifically, there are several ways to achieve this:

The first type, corresponding to the implementation manner a of the first signaling, if the first signaling carries indication information indicating that the terminal starts the WLAN AP search and measures the signal strength information and/or the signal quality information, the terminal acquires the WLAN AP that can be detected. The identifier information and the corresponding signal strength information and/or signal quality information are sent to the network side to transmit second signaling that carries the acquired WLAN AP identification information and the corresponding signal strength information and/or signal quality information.

The second type, corresponding to the implementation manner b of the first signaling, if the first signaling carries the identification number of the WLAN AP, the terminal detects the signal strength of the WLAN AP corresponding to the identification number of the WLAN AP carried in the first signaling. The information and/or signal quality information is sent to the network side for carrying the detected signal strength information and/or signal quality information and the second signaling of the corresponding WLAN AP identification number.

The third type, corresponding to the implementation manner c of the first signaling, if the first signaling carries the identification number and the index number of the WLAN AP, the terminal detects the signal of the WLAN AP corresponding to the identification number of the WLAN AP in the first signaling. The strength information and/or the signal quality information is sent to the network side with the second signaling carrying the detected signal strength information and/or signal quality information and the corresponding index number.

The fourth type, corresponding to the implementation manner d of the first signaling, if the first signaling carries the service set identifier SSID of the WLAN AP, the terminal detects the WLAN AP having the SSID in the first signaling, and acquires the detected The signal strength information and/or the signal quality information of the WLAN AP and the identifier information of the corresponding WLAN AP are sent to the network side to transmit the second received signal strength information and/or signal quality information and the corresponding WLAN AP identification information. Signaling.

The method for realizing the control plane positioning in the embodiment of the present invention is described in detail below through several specific embodiments.

In the following specific embodiments, the RSSI of the WLAN AP is measured by the terminal as an example for description.

In a first specific embodiment, when the network-assisted global satellite navigation A-GNSS positioning terminal fails, the terminal is accurately located based on the WLAN. details as follows:

If the terminal finds that it cannot receive more than 4 satellite signals, the reporting server cannot detect enough satellite signals and the positioning fails. After receiving the location server, the location server may initiate WLAN positioning based on the indication of the terminal and the location of the terminal, while the terminal is based on the A-GNSS positioning.

Specifically, the location server sends related information of the WLAN AP to the terminal, and the related information may be provided by using the LTE positioning protocol to provide auxiliary data related signaling.

The information about the WLAN AP may include one of the following contents:

a. Instructing the terminal to initiate WLAN AP search and measure indication information of signal strength information and/or signal quality information;

b. The identification number of the WLAN AP (such as the basic service set identifier BSSID, that is, the MAC address of the WLAN AP) may also include the measurement amount (signal strength information and/or signal quality information). If the measurement required by the terminal is only RSSI, it may or may not include the measurement;

c. The identification number of the WLAN AP and the index number of the WLAN AP, which may also include the measurement quantity. If the measurement required by the terminal is only RSSI, it may or may not include the measurement;

d. The service set identifier SSID of the WLAN AP, for example, the operator's network code, China Mobile Communications Corporation (CMCC).

The following is only an example of the terminal measurement RSSI, and the implementation process is the same for other measurement quantities.

After receiving the relevant information of the WLAN AP, the terminal can continue to monitor the satellite signal on the one hand, and turn on the measurement of the WLAN AP on the other hand. The terminal is handled as follows:

Corresponding to the implementation manner a of the related information of the WLAN AP, the terminal detection can be monitored. The BSSID and RSSI of the WLAN AP, reporting the BSSID and the corresponding RSSI;

Corresponding to the implementation manner b of the WLAN AP, the terminal detects the RSSI of the WLAN AP determined by the WLAN AP identification number BSSID, and reports the BSSID and the corresponding RSSI.

Corresponding to the implementation manner c of the WLAN AP, the terminal detects the RSSI of the WLAN AP determined by the WLAN AP identification number BSSID, and reports the index number and the corresponding RSSI.

Corresponding to the implementation manner d of the related information of the WLAN AP, the terminal detects the BSSID of the WLAN AP with the SSID carried in the related information of the WLAN AP and the corresponding RSSI, and reports the BSSID and the corresponding RSSI.

After the terminal reports the measurement result, the location server performs location calculation according to the measurement result of the WLAN AP reported by the terminal.

The transmission of the auxiliary data in the existing protocol also has two methods of requesting and actively reporting. Specifically, as shown in FIG. 3, the destination device (terminal) sends an auxiliary data request to the server (location server), which may indicate the required information. Auxiliary data; the server transmits auxiliary data to the target device, wherein the transmitted auxiliary data should be consistent with the auxiliary data requested in the auxiliary data request sent by the destination device; optionally, the server may deliver one or more LPP assistance to the target device Data message.

The second embodiment is similar to the first embodiment. If the terminal can detect multiple satellite signals, but the signal quality of the satellite signal is poor, such as the RSSI is low, the positioning server can be based on the RSSI of the satellite signal reported by the terminal. It is judged that the terminal uses the A-GNSS method for positioning is very inaccurate (for example, when the RSSI is lower than the preset value), and the related process of initiating WLAN positioning is initiated. The process of WLAN positioning is the same as the process of performing WLAN positioning in the first embodiment, and details are not described herein again.

In a third specific embodiment, when the A-GNSS positioning terminal fails or the positioning is inaccurate, the positioning server may initiate a control plane positioning method of the other wireless mobile communication system except the A-GNSS (for example, CELL ID+TA+AOA, Or, at the same time, U-TDOA) initiates WLAN positioning. The process of WLAN positioning is the same as the process of performing WLAN positioning in the first embodiment, and details are not described herein again. The terminal reports the positioning measurement results of other control plane positioning methods (for example, CELL ID+TA+AOA, or U-TDOA), and the identification information of the WLAN AP and the corresponding RSSI. The positioning server jointly uses the measurement results reported by the two positioning methods to calculate and correct the position of the terminal.

In a fourth specific embodiment, when the existing positioning methods (CELL ID+TA+AOA, U-TDOA, A-GNSS, etc.) provided by the wireless mobile communication system fail to meet the required accuracy, the positioning server determines the approximate location of the terminal. Whether the number of WLAN APs in the vicinity of the location (obtained according to the existing positioning method or obtained according to the location of the cell) is greater than a preset value (for example, the preset value is 5). If it is greater than, the WLAN positioning process may be started. Otherwise, the WLAN positioning process may be started. The positioning process is not initiated. The process of WLAN positioning is the same as the process of performing WLAN positioning in the first embodiment, and details are not described herein again.

In a fifth specific embodiment, if the terminal cannot detect signals of three or more cells at the same time by using the OTDOA positioning method, it is determined that the measurement accuracy of the method is poor, the positioning accuracy is low, and the approximate location of the terminal is If the number of WLAN APs in the vicinity is sufficient, or the number of WLAN APs in the vicinity is sufficient (that is, when the value is greater than the preset value), the positioning server may provide related information of the WLAN AP to the terminal to initiate WLAN positioning. The process of WLAN positioning is the same as the process of performing WLAN positioning in the first embodiment, and details are not described herein again.

In a sixth specific embodiment, as shown in FIG. 4, the main processes of performing WLAN assisted positioning are as follows:

Step 401: The positioning server (such as E-SMLC) locates the UE by using a terminal positioning method existing in the wireless communication system;

Step 402: The UE reports the positioning result information, including the indication of the positioning failure or the positioning result.

Step 403: The positioning server determines whether to initiate WLAN positioning according to the positioning result information reported by the UE, the capability of the UE, and the distribution of the WLAN.

Step 404: The positioning server determines to initiate WLAN positioning, and sends auxiliary data to the UE, where the auxiliary data includes related information of the WLAN AP.

Step 405: The UE performs WLAN AP measurement according to the information about the WLAN AP provided by the positioning server, and reports the WLAN AP identification information and the corresponding measurement result.

Step 406: The location server performs the location calculation based on the WLAN AP identification information and the corresponding measurement result, and the subsequent specific calculation process is the same as the prior art, and details are not described herein again.

The UE reports the indication information of the WLAN AP measurement when the capability information is reported. The positioning server determines that the UE can perform the WLAN AP measurement according to the capability information reported by the UE, and then starts the WLAN positioning process.

The location server may also provide related information of the WLAN AP by using a location information transmission process of the LPP protocol.

The WLAN AP identification information and the corresponding measurement result reported by the UE may be implemented by using a location information transmission process of the LPP protocol.

Specifically, the location information transmission process of the LPP protocol is as shown in FIG. 5. The location information may be an actual location estimation, or may be information required for calculating a location (such as a wireless signal measurement amount, etc.). The location information transmission may be a request/response mode or an active reporting mode. Specifically, the server sends a location information request to a target device (such as a UE), which may indicate a required location information type and an associated Quality of Service (QoS); in response, the target device transmits the requested location to the server. Information; optionally, the target device transmits one or more LPPs to the server for providing location information.

In the seventh embodiment, the WLAN AP is used for positioning of the control plane, which can be used as an independent positioning mode. When a positioning process starts, the E-SMLC directly determines whether to use the WLAN positioning terminal according to the location of the serving cell where the terminal is located and the distribution of the WLAN AP, and does not initiate other positioning processes; the network side provides information about the WLAN AP to the network side. The terminal performs the WLAN AP measurement and reports the relevant WLAN measurement result; the positioning server E-SMLC performs the location calculation of the terminal according to the result reported by the terminal.

Based on the same principle, in the third embodiment of the present invention, a terminal locating device is also provided. For the specific implementation, refer to the specific implementation of the locating server in the method part, and the repeated description is not repeated, as shown in FIG. The equipment mainly includes:
