The steps illustrated in the flowchart of the figures may be executed in a computer system such as a set of computer executable instructions. Also, although logical sequences are shown in the flowcharts, in some cases the steps shown or described may be performed in a different order than the ones described herein.

With the continuous development of electronic technology, electronic products based on location services are gradually popularized, and the demand for location information of various wireless devices is increasing. When it is inconvenient to obtain positioning information through satellite navigation systems, the corresponding base stations obtain corresponding Location information can be a way to achieve positioning. In the embodiment of the present invention, location information of a station that cannot acquire own positioning information is calculated based on location information of a website broadcast that has acquired its own location information.

FIG. 1 is a flowchart of a method for implementing site location according to an embodiment of the present invention. As shown in FIG. 1, the method provided in this embodiment includes the following steps:

Step 100: The station that cannot obtain the positioning information of the self obtains the location information of the website broadcast that has obtained the location information of the plurality of locations.

In this step, the site that has acquired its own location information (also referred to herein as the first site) includes: a base station having a satellite navigation system receiving device and having the capability of acquiring location information from the satellite navigation system; or, calculated A base station that derives its own location information.

In this step, the number of sites that have acquired their own location information is three or more.

Before this step, the site that has obtained its own location information will broadcast its obtained location information (such as location coordinate information) through the broadcast channel in its wireless communication network; instead of having a satellite navigation system receiving device, Or a station that cannot obtain its own location information from the satellite navigation system can obtain the location information of the broadcast by searching for signals transmitted by other stations in the same network.

Embodiments of the present invention emphasize that a base station having a satellite navigation system receiving device and having the capability of acquiring location information from a satellite navigation system broadcasts its obtained location information (such as location coordinate information) to its own wireless station. In the communication network, how to broadcast the location information and how to obtain the broadcast location information is a common technical means for those skilled in the art, and is not intended to limit the scope of protection of the present application, and details are not described herein again.

The wireless communication network described in the embodiments of the present invention includes a wireless wide area network (WWAN), a wireless local area network (WLAN), and the like, wherein the wireless wide area network includes, but is not limited to, a global mobile communication system (GSM), a wideband code division multiple access mobile communication system ( WCDMA), Time Division Synchronous Code Division Multiple Access (TD-SCDMA), Long Term Evolution (LTE/LTE-A), etc.

The step further includes: screening the received broadcast information by using a site that cannot obtain its own positioning information (also referred to as a second site herein), for example, selecting available broadcast information according to signal strength, multipath information obtained by channel estimation, and the like. For subsequent acquisition of location information carried by it, such as a broadcast signal whose signal strength is greater than or equal to a preset intensity threshold. The specific implementation of the method for obtaining the available broadcast information is not intended to limit the scope of the present application, and is easily implemented by those skilled in the art based on the technical solutions described in the present application, and details are not described herein again.

Step 101: The station that cannot acquire its own positioning information acquires the path loss between itself and the station that broadcasts the location information according to the power of the broadcasted broadcast signal, and acquires the distance between itself and the station that broadcasts the location information.

In this step, the station obtains the location of the base station that initiates the broadcast signal by parsing the effective broadcast signal. Information; the station calculates the path loss between the two stations by the transmission power of the known broadcast signal and the received power locally obtained by the station, and according to the time difference of the signal transmission and reception, the multipath information obtained by the channel estimation, and the like, Calculate the distance between the base station that initiated the broadcast signal and the site. It should be noted that, in this step, according to the broadcast signal carrying the location information of the base station, the distance between the base station that initiates the broadcast signal and the local station may be obtained by using many related methods.

Step 102: The station that cannot acquire the positioning information acquires its own location information according to the location information of the obtained location information of each broadcast location information and the path loss and distance between the stations of each broadcast location information.

In this step, the specific implementation of calculating the location of the site according to the location information of the multiple sites, etc., may be implemented by a plurality of related methods, and the specific implementation is not limited to the scope of protection of the present application, and details are not described herein again.

The embodiment of the present invention emphasizes that a base station having a satellite navigation system receiving device and having the capability of acquiring location information from a satellite navigation system broadcasts its obtained location information (such as location coordinate information) to its own wireless communication. The station in the network, without the satellite navigation system receiving device, or having the capability of acquiring the location information from the satellite navigation system, may be based on the location information of the base station carried in the received broadcast information and according to the obtained location information of the base station. The location information of the site itself is calculated, thereby realizing the location of the site in the dense wireless communication network.

The station that cannot obtain the self-positioning information in the embodiment of the present invention may be, for example, a small cell (Small Cell), a pico cell, a femto cell, or the like, or may be a mobile terminal.

Before the step 100, the method provided by the embodiment of the present invention further includes: the station that has obtained the location information of the user may initiate the broadcast of the location information periodically, or may initiate the broadcast by the upper layer.

The method provided by the embodiment of the present invention further includes: the location information that the site will obtain in the wireless communication network where the station is located, such as a small cell (Small Cell), a pico cell, a femto cell, or the like. Broadcast in the middle.

When the location information of the site is calculated in step 102, the method provided by the embodiment of the present invention further The method includes: calculating a confidence level corresponding to the location information. Among them, the confidence is used to characterize the accuracy of the location information calculated by the site so that other sites can use it when selecting a reference site. For example, the confidence of the site can be calculated according to the confidence of the sending site and the quality of the received signal. The specific implementation can adopt many related methods, and the scope of protection of the present application is not limited, and details are not described herein again. In general, sites that obtain location information directly through satellite navigation systems have the highest confidence, while sites that refer to other sites to obtain location information for the site have reduced confidence. Confidence is only one way of characterizing the accuracy of the calculated position information in this application, and the present application also includes the broadest scope in which other principles and features are consistent with confidence.

In this way, when the site needs to calculate the location information again, if the confidence calculated again is higher than the confidence corresponding to the previously calculated and stored location information, the recalculated location information and the confidence level replace the stored location information and the confidence. . Such processing further improves the accuracy of the location information of the site.

It should be specially noted that, for the mobile terminal, since there is a possibility of moving, it is possible to move from a place with high confidence to a place with low confidence, and in this way, the position is not updated. Therefore, in the embodiment of the present invention, for the case where the second station is a mobile terminal, when the location information needs to be calculated again, it may be processed as follows: if the confidence level calculated again is higher than a preset confidence threshold, it will be calculated again. The location information and confidence replace the stored location information and confidence.

At the same time, when the location information that the site will obtain is broadcasted in the wireless communication network in which it is located, the confidence corresponding to the location information is also broadcasted to characterize the accuracy of the location information of the site, so that other sites are selecting them. When receiving a site, you can use the location of the high-confidence site for calculation.

FIG. 3 is a schematic diagram of an application scenario of a site location according to an embodiment of the present invention. The specific implementation of the method provided by the embodiment of the present invention is described in detail below with reference to FIG. 3 .

As shown in FIG. 3, it is assumed that the BS 201, the BS 202, and the BS 203 are outdoor macro base stations, have satellite navigation system receiving devices, and are capable of efficiently receiving signals transmitted from the satellite navigation system to determine the location of the base station. As shown in FIG. 3, in a dense heterogeneous wireless network deployed in an indoor hotspot area, FBS201 to FBS 205 are Femto small base stations in the heterogeneous wireless network. These small base stations do not have satellite navigation system receiving equipment, or cannot receive satellite signals effectively because they are indoors. However, these small base stations actively search for signals transmitted by other stations in the same frequency band in the specified frequency band, and parse valid valid position information with coordinates of respective station positions, and use the obtained multiple effective position information to obtain Its own location. For example:

For example, after determining the location of the own station by the satellite navigation system, the BS 201, the BS 202, and the BS 203 in FIG. 3 transmit their location information and the confidence of the location information through a specific broadcast channel. Since the location information is directly obtained from the satellite navigation system, the confidence of the location information can be set to the highest at this time. At this time, if the FBS 201 and the FBS 202 in FIG. 3 effectively calculate the position coordinates and the confidence of the own station by effectively analyzing the position information transmitted by the three outdoor macro base stations having the highest confidence, and save the information and send it out. . In this case, the location information calculated by the BS 201 and the FBS 202 is from the macro base station, not directly from the satellite navigation system, so the confidence of the location information is lower than the confidence of the location information of the macro base station such as the BS 201. .

For another example, assume that the FBS 203 in FIG. 3 can receive signals from three outdoor macro base stations and FBS 201 and FBS 202, and assume that although the outdoor macro base stations BS201 and BS 203 have significantly higher confidence than the FBS 201 and the FBS 202, the FBS 203 receives the BS 201 and If the signal of BS203 is not ideal, such as the receiving power is too low, or the location information is incorrect, then the FBS203 will choose BS202 and FBS201 and FBS202 on the premise of comprehensive consideration of signal quality and confidence (some strategies can be set in advance). The location information is used to calculate the location coordinates and confidence of the site, save the calculated information and send it out.

Similarly, if the FBS 204 and the FBS 205 in FIG. 3 are not ideal due to the received macro base station, the location information transmitted by the FBS 201, FBS 202, and FBS 203 with lower confidence relative to the macro base station may be selected to calculate the site. Location coordinates and confidence. In this case, the location information of the site is a small base station that is obtained in whole or in part from other locations obtained by the technical solution provided by the embodiment of the present invention, so that the calculated location information has lower confidence than the entire navigation system. Determine the location of your site to calculate the situation.

Optionally, when the site calculates the location information and confidence of the site, the information is saved locally. Subsequently, when the method shown in FIG. 1 provided by the embodiment of the present invention is performed again, the confidence level corresponding to the currently calculated position information is compared with the confidence of the previously saved history, and the current calculated confidence level is obtained. When the value is greater than the historical value, the location information calculated before the method shown in FIG. 1 provided by the embodiment of the present invention and the information saved before the confidence update are used. For example, FBS205 calculates the location information and confidence of the site through FBS201, FBS202, and FBS203, and saves the information locally. However, when the validity information of the outdoor macro base station BS204 is received and the confidence level corresponding to the position information is calculated, it is obvious that the confidence level corresponding to the position information at this time is higher than the previously saved historical value. The saved location coordinates and confidence are replaced with the location information and confidence obtained from the broadcast information of the BS 204, and the new information is sent out.

It should be noted that the UE 201 in FIG. 3 is a mobile terminal placed in a heterogeneous wireless network, and the mobile terminal is also calculated according to the technical solution provided by the embodiment of the present invention according to the location information sent by multiple FBS small base stations in the network. Determine its own location information.
