It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
The steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.
With the continuous development of electronic technology, electronic products based on location services are gradually popularized, and the demand of various wireless devices for location information is increasing day by day, the inventor finds that when the positioning information is inconvenient to obtain through a satellite navigation system, the corresponding location information is obtained through a corresponding base station, and the inventor can become a way for realizing the positioning function. The technical scheme provided by the invention is just based on the position information broadcasted by the station which has acquired the self position information, and the position information of the station which can not acquire the self positioning information is calculated. The station (also referred to as the first station herein) that has acquired the self-location information includes, but is not limited to: a base station having a satellite navigation system receiving device and acquiring position information from a satellite navigation system; or, the base station calculates the position information of the station itself. Sites (also referred to herein as second sites) that are unable to acquire self-location information include, but are not limited to: a base station or mobile terminal that does not have a satellite navigation system receiving device or that does not have location information obtained from a satellite navigation system.
Fig. 1 is a flowchart of an embodiment of a method for implementing site location according to the present invention, as shown in fig. 1, including:
step 100: the station which can not obtain the self-positioning information obtains the position information broadcast by a plurality of stations which have obtained the self-positioning information.
In this step, the station (also referred to as a first station herein) that has acquired the own location information includes: a base station having a satellite navigation system receiving device and acquiring position information from a satellite navigation system; or, the base station calculates the position information of the station itself.
In this step, the base stations that have acquired the own location information include three or more.
Before the step, the site which has acquired the self-position information broadcasts the acquired self-position information such as position coordinate information in a wireless communication network where the site is located through a broadcast channel; the station which does not have the satellite navigation system receiving equipment or can not obtain the self position information from the satellite navigation system can obtain the broadcast position information by searching signals sent by other stations of the same system in the network.
It is emphasized that, the base station having the receiving device of the satellite navigation system and acquiring the location information from the satellite navigation system broadcasts the acquired location information of itself, such as the location coordinate information, to the wireless communication network where it is located, and it is the conventional technical means of those skilled in the art how to broadcast the location information and how to acquire the broadcasted location information by the station, and it is not used to limit the protection scope of the present invention, and it is not described here again.
The wireless communication network described in the present invention includes a Wireless Wide Area Network (WWAN), a Wireless Local Area Network (WLAN), etc., wherein the wireless wide area network includes, but is not limited to, global system for mobile communications (GSM), wideband code division multiple access mobile communication system (WCDMA), time division synchronous code division multiple access communication system (TD-SCDMA), long term evolution communication system (LTE/LTE-a), etc.
The method also comprises the following steps: the station (also referred to as the second station herein) that cannot acquire the self-positioning information filters the received broadcast information, for example, selects available broadcast information according to the signal strength, multipath information obtained by channel estimation, and the like, so as to subsequently acquire the position information carried by the station, for example, a broadcast signal whose signal strength is as strong as greater than or equal to a preset strength threshold, and the like. The specific implementation of how to screen to obtain available broadcast information is not intended to limit the scope of the present invention, and for those skilled in the art, the implementation is easy based on the technical scheme described in the present invention, and details are not described here.
Step 101: the station which can not obtain the self-positioning information obtains the path loss between the station which can not obtain the self-positioning information and the station which broadcasts the position information according to the power of the broadcasted broadcast signal, and obtains the distance between the station which can not obtain the self-positioning information and the station which broadcasts the position information.
In this step, the station obtains the position information of the base station initiating the broadcast signal by analyzing the effective broadcast signal; the station calculates the path loss between the two stations according to the known transmitting power of the broadcast signal and the locally obtained receiving power of the station, and calculates the distance between the base station initiating the broadcast signal and the station according to the time difference of signal transceiving, the multipath information obtained by channel estimation and other data. 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 initiating the broadcast signal and the station may be obtained by using a plurality of existing methods.
Step 102: the station which can not obtain the self-positioning information obtains the self-positioning information according to the obtained position information of the station broadcasting the position information and the path loss and the distance between the station and the station broadcasting the position information.
The specific implementation of calculating the position of the site according to the position information of the multiple sites in this step may be implemented by many existing methods, and how to implement the position information is not limited to the protection scope of the present invention, and is not described herein again.
The invention emphasizes that a station which is provided with a satellite navigation system receiving device and is provided with a base station for acquiring position information from a satellite navigation system broadcasts the acquired position information of the station, such as position coordinate information, to a wireless communication network in which the station is positioned, and the station which is not provided with the satellite navigation system receiving device or is not provided with the position information of the base station which is acquired from the satellite navigation system can calculate the position information of the station according to the position information of the base station which is carried in the received broadcast information. Thereby enabling the location of stations in dense wireless communication networks.
The station incapable of acquiring self-positioning information in the invention can be a small base station (SmallCell), a pico cell (Picocell), a femto cell (Femtocell), and the like, and can also be a mobile terminal.
The method of the invention also comprises the following steps: the station having acquired the self-location information may initiate the broadcast of the self-location information at the time of starting or periodically, or may be instructed by an upper layer to initiate the broadcast.
When the station is, for example, a small base station (SmallCell), a pico cell (Picocell), a femto cell (Femtocell), etc., the method of the present invention further includes: the station broadcasts the acquired position information of the station in the wireless communication network in which the station is positioned.
When the location information of the local station is calculated in step 102, the method of the present invention further includes: and calculating the confidence corresponding to the position information. Wherein the confidence level is used for characterizing the accuracy of the position information calculated by the station, so that other stations can use the position information when selecting the reference station. The confidence of the station can be calculated by the confidence of the sending station and the quality of the received signal, and the specific implementation can adopt a plurality of existing methods, and does not limit the protection scope of the invention, which is not described herein again. Generally, the confidence level of a station directly acquiring position information through a satellite navigation system is highest, and the confidence level of a station acquiring position information of the station by referring to other stations is reduced. Confidence is just one way in which the present invention can characterize the accuracy of the calculated position information, and the present invention also includes the broadest scope of other principles and features consistent with confidence.
In this way, when the station needs to calculate the position information again, if the calculated confidence coefficient is higher than the confidence coefficient corresponding to the position information calculated and stored before, the position information and the confidence coefficient calculated this time are used for replacing the stored position information and the confidence coefficient. By such processing, the accuracy of the position information of the local station is further improved.
It should be noted that, in the case of a mobile terminal, since there is a possibility of movement, that is, there is a possibility of moving from a location with high confidence to a location with low confidence, the position is not updated in this way. Therefore, in the present invention, when the second station is a mobile terminal and the position information needs to be calculated again, the following processing can be performed: and if the confidence coefficient calculated again is higher than the preset confidence coefficient threshold value, replacing the stored position information and the stored confidence coefficient with the position information and the confidence coefficient calculated this time.
Meanwhile, when the station broadcasts the acquired self position information in the wireless communication network where the station is located, the confidence corresponding to the position information is broadcast at the same time to represent the accuracy of the position information of the station, so that when other stations select the stations received by the stations, the positions of the stations with high confidence can be selected for calculation.

Fig. 3 is a schematic view of an application scenario of the embodiment of site location in the present invention, and a detailed implementation of the method in the present invention is described below with reference to fig. 3 as an example.
As shown in fig. 3, it is assumed that BS201, BS202, and BS203 are outdoor macro base stations, have satellite navigation system receiving devices, and can effectively receive and resolve signals sent by the satellite navigation system to determine the position of the local base station. Referring to FIG. 3, in a dense heterogeneous wireless network configured in an indoor hot spot area, FBS201 to FBS205 are Femto base stations in the heterogeneous wireless network. These small base stations do not have satellite navigation system receiving equipment or cannot effectively receive satellite signals because they are indoors. However, these small base stations actively search for signals transmitted by other stations of the same system in the specified frequency band, and then analyze effective location information with respective station location coordinates from the signals, and use the obtained effective location information to obtain their own location. By way of example:
for example, after BS201, BS202, and BS203 in fig. 3 determine the location of their own station through the satellite navigation system, their location information and the confidence of the location information are sent out through a specific broadcast channel. Since the position information thereof is directly acquired from the satellite navigation system, the confidence of the position information thereof at this time can be set to be the highest. At this time, if the FBSs 201 and the FBS202 in fig. 3 effectively resolve the position information transmitted by the 3 outdoor macro base stations with the highest confidence level, the position coordinates and the confidence level of the station itself are calculated, and the information is stored and transmitted to the outside. In this case, the calculated position information of the BS201 and the FBS202 is from the macro base station, not directly from the satellite navigation system, and therefore, the confidence of the position information is lower than that of the macro base station such as the BS 201.
For another example, suppose that the FBS203 in fig. 3 can receive signals of 3 outdoor macro base stations and the FBSs 201 and 202, and suppose that, although the confidences of the outdoor macro base stations BS201 and BS203 are significantly higher than those of the FBSs 201 and FBS202, since the FBS203 receives signals of the BS201 and BS203 undesirably, such as the received power is too low, or the analyzed position information is incorrect, etc., the FBS203 chooses to use the position information of the BS202 and the FBSs 201 and FBS202 to calculate the position coordinates and the confidences of the local station, and stores the calculated information and transmits the calculated information to the outside, under the premise of comprehensively considering the signal quality and the confidences (some strategies may be preset here).
Similarly, if the FBS204 and the FBS205 in FIG. 3 are not ideal due to the received signals from the macro base station, the FBS201, the FBS202 and the FBS203 with low confidence relative to the macro base station may choose to use the transmitted position information to calculate the position coordinates and confidence of the station. In this case, the position information of the station is wholly or partially from other small base stations of the position acquired by the technical solution provided by the present invention, so the confidence of the calculated position information is lower than that of the position information calculated by determining the position of the station through a satellite navigation system.
Further, after the site calculates the location information and confidence of the site, the information is stored locally. Subsequently, when the method shown in fig. 1 of the present invention is executed again, the currently calculated confidence level is compared with the confidence level of the history stored before, and when the currently calculated confidence level is greater than the history value, the position information and the confidence level calculated when the method shown in fig. 1 of the present invention is executed this time are used to update the information stored before. Such as: the FBS205 calculates the position information and confidence of acquiring the station by the FBS201, the FBS202 and the FBS203, and stores the information locally. However, when it is obvious that the confidence of the location information at this time is higher than the previously stored history value after receiving the valid information of the outdoor macro base station BS204 and calculating the confidence of the location information, it is necessary to replace the location coordinates and the confidence that have been stored with the location information and the confidence that are currently obtained from the broadcast information of the BS204 and send the new information to the outside.
It should be noted that, the UE201 in fig. 3 is a mobile terminal disposed in a heterogeneous wireless network, and the mobile terminal is also position information that can be sent through a plurality of FBS small base stations in the network, and the position information of itself is calculated and determined through the technical solution provided by the present invention.
Although the embodiments of the present invention have been described above, the above description is only for the convenience of understanding the present invention, and is not intended to limit the present invention. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
