Description

A GEOLOCATING SYSTEM FOR A MOBILE DEVICE

Field of the Invention

The present invention relates to a geolocating system for a mobile device. Specifically, the geolocating system information from cellular towers and cell models to determine the position of the mobile device.

Background of the Invention

The location of a mobile device may be determined using alternative methods other than the usual satellite-based signals like Global Positioning System (GPS), and these typically use information from cellular towers. With the advancement of mobile technology to 3G/4G, mobile devices no longerkeeps track of complete Globally unique Identification (GUID) of the neighboring cells, only non-unique local radio parameter for other neighboring Cell Tower. By not keeping track of the GUID of neighboring cells, this improves the performance and reduces power consumption of the mobile device. Therefore, the traditional method to geo-locate a mobile device using GUID of registered cell and neighboring cells is no longer viable. The traditional method is unable to distinguish the ambiguity of which neighboring cells the mobile device is able to detect.

One of these methods is known as a disambiguation technique described in US 2014/0243010. The disambiguation technique uses disambiguation information that is associated with the cellular tower that the mobile device is currently based on by using a radio scene received at the mobile device and mapping it to an estimate of the devices location. The radio scene is typically a list of all the radio transmitters or cellular towers that the mobile may detect. The mapping may then be carried out using techniques like trilateration or based on a predictive model learnt undersupervision, in orderto unambiguously identify as many of the neighboring visible transmitters as possible. However, the disambiguation technique requires a large amount of processing compared to traditional methods and is also prone to disambiguation errors. Conventional methods essentially work by disambiguating the non-unique parameters of the neighboring towers to their associated globally unique IDs.

Summary of the Invention

The above and other problems are solved and an improvement in the art is made by a method and system in accordance with this invention. A first advantage in accordance with this invention is that a mobile device is able to determine its geolocation without using GPS and by using existing cellular tower information. This provides a mobile device with a fast and accurate geolocation service without requiring extra infrastructure or modifications to the cellular network and allows for geolocation indoors or places that do not have satellite coverage. A second advantage in accordance with this invention is the faster determination of the geolocation of a mobile device. This is because every tagged record acts as a unique cell model, thus requiring less processing and making the search and estimation shorted. A third advantage in accordance with this invention is the lack of ambiguity. This is improves the accuracy by using the unique cell models generated with the local non-unique parameters having the same global unique parameters.

In accordance with a first aspect of the present invention, there is provided a method for determining a geolocation of a mobile device comprising capturing a plurality of first radio parameters of a first cellular tower, then capturing a plurality of second radio parameters of a second cellular tower, wherein the plurality of second radio parameters are locally unique radio parameters. The method includes tagging the plurality of second radio parameters to the plurality of first radio parameters. The method further includes generating a plurality of base cell models using the plurality of firstand second radio parameters, then extracting a plurality of resultant cell models based on a position query from the mobile device and the plurality of base cell models, and statistically determining the geolocation of the mobile device using the plurality of resultant cell models.

Description of an Embodiment of the Invention

The present invention comprises a method of deriving the geolocation ofa mobile device by taking advantage of the ambiguity and tagging the local non-unique parameter to have the same Global unique parameter to generate a unique Cell Model, and the extracting the cell models to derive the geolocation of the mobile device. This method may provide better accuracy compared to conventional methods as the error of the positioning technology is confined to one cell. The present invention may capture radio parameters in a different manner from conventional methods, by using the radio parameter ambiguity captured by the mobile device. Conventional methods try to unambiguously identify as many of the neighboring visible transmitters as possible in order to apply disambiguation of non-unique tower parameters for geo-location of the mobile device.

- 8 According to some embodiments the mobile data collection process 110 (shown in Figure 1) performed by the method and system is described as follows. The process 110 may begin with capturing radio parameters 120, followed by capturing the GPS position 130. The next step being to tag the local unique parameters and position with global unique parameters 140, followed by inserting the record with the position into a database 150.

In the embodiments, some examples of radio parameters are: the globally unique tower ID of a cellular tower, UARFCN, PSC and RSSI, or any other globally unique ID that is known in the art. Figure 5 shows cellular towers 510, 520, 530 with one of them 510 being the base station cellulartowerand the mobile device 515 capturing the radio parameters. Examples of globally unique tower ID may be a mobile country code (MCC), mobile network code (MNC), location area code (LAC), Cell ID (CID), or any other fields that may provide the same function of identifying a cellular tower. Radio parameters may also be combined, for example, UARFCN and PSC may be combined together to form a local unique identifier, although one skilled in the art would appreciate that other combinations are also possible to arrive ata local unique identifier for a cellular tower. Looking at Figure 6, the radio parameters are tallied with GPS position data transmitted by satellites 640. This may also collected by a mobile device 615, and the information is sent back to a server 650. In other embodiments, other types of location based services and technology may also be used instead of GPS, for example real-time location system (RTLS) like Ultra-Wideband (UWB), Bluetooth Low Energy (BLE), Wi-Fi positioning system (WPS). Also some embodiments also allows the user to manually enter the coordinates and define them to preference, which may be in various forms. With sufficient data points to make a model of the cells, the model of the cells can be generated to track mobile devices without the need for further infrastructure or even modifications to the mobile device. For the purposes of location tracking indoors, some embodiments would have a shop name, description, or unit number in place of the coordinates. In some embodiments, the mobile device 615 (515) uses an application to obtain the technical parameters of a mobile network, and the application may have the ability to covert the technical parameters into estimated coordinates. The server 650 may be associated with a database (not shown in Figure 6).

- 9 In some embodiments as shown in Figure 7, the radio parameters with (GPS) position data 720, 730 may be inserted into a database 750, and in the process the local unique parameter is tagged to have the same global unique parameter 725. In some embodiments, this is done by tagging the local unique radio parameter of the neighboring cell to the global unique radio parameter of the connected cell to generate a unique cell model. Compared to existing methods, tagging the local unique parameter to have the same global unique parameter to generate a unique cell model makes the process fastersince every tagged record acts a unique cell model. An example of tagging can be associating the local unique parameter with the global unique parameter.

According to some embodiments the model generation process 210 (shown in Figure 2) performed by the method and system is described as follows. The process 210 may begin with generating data models for each cell global unique cell-ID and tagged local unique parameter from the database 220, and examples of this are described later and shown in Figures 8-11. The databases 750, 850 and 950 may be the same database. Database 750 allows the records (720,730) from the mobile device to be inserted into the database 750, while database 850 demonstrates how the data collected is used to make a model, 820 and 830 depicts examples of records on a map. The generated model 920 corresponds to the record in database 950. The following step is to insert the cell models or update the cell models in the model database 230, and this is described and shown in Figure 12.

According to some embodiments, a model 820, 830 is generated using the information from the database 850 and the outcome may be found in Figure 8. It may be seen that using the information, the model for CTollPoRSo 820 and CT0UP0RS11 830 may be generated. By repeating this process for differing values from the database 950, a model for CTollPo 920 may be generated as shown in Figure 9. In Figure 10, another model 1022 may be generated using further values of local unique identifiers from the database 1050 and is shown has an overlay on the CTollPo model 1020 of Figure 9. Repeating the process (in Figure 11) for yet further values of local unique identifiers from the database 1150, another model 1124 is generated, with CTollPo model 1120 shown in comparison. The step of inserting or in some cases updating the models in the model database in shown in Figure 12, whereby the various models generated 1220,1222,1224 are populated into the database 1250 accordingly, and this may

- 10 be done by applying geometric and/or statistical methods such as contouring, interpolation, triangulation, fingerprinting.

According to some embodiments the position query and model extraction process 310 (shown in Figure 3) performed by the method and system is described as follows. The process 310 may begin with a position query request based on the one or a combination of the following fields reported by mobile device: global unique identification (GUID), local unique parameter, RS SI, etc 320. Based on the information provided, the data model database is searched 330, then the matching data or resultant cell model may be extracted 340 for the queried parameter or parameters along with the coordinates, location or geolocation or any other form outcome that may indicate the geolocation of the mobile device.

In other embodiments, the position estimation and result process 410 (shown in Figure 4) that may be performed by the method and system is described as follows. The process 410 begins by determining the method of presentation, either using overlap, triangulation or exclusion 420. Then proceeds to extract the appropriate data models based on the query parameters 430, and deriving the position based on the method applied, for example most overlap, point of intersect or exclusion 440. The position results may then be derived using statistical methods like normal, Gaussian, point confident 450 and the derived results may be presented, either using coordinates (x, y, radius) orany otherform of geolocation reporting 460. By way of example, if point confident is used, the derived location will have coordinates like (x, y) and a confidence level that the point is of a certain accuracy.

An embodiment is shown in Figure 13, where a mobile device is requesting or sending a query for itgeolocation or position, a query 1330 is sent to the database 1350, and various cell models are extracted in response 1340, 1342,1344, 1346. The query is then resolved shown in Figure 14 by estimating the position of the mobile device using the extracted models 1440, 1442, 1444, 1446, and the position of the mobile device may be determined using the resultant cell model 1460, for example by highest overlapping, triangulation or exclusion method, or any other know method of determining intersection between the extracted models. This result 1560 is presented to the mobile device (and the user) in Figure 15 by deriving the position 1570 through statistical methods using estimation data, for example normal, Gaussian, point confident, or any other
