For example, the location of the vehicle may be determined using information systems maintenance traffic flows at the location of cellular devices that are located in the drivers, thus forming the picture of the transport stream. The location of the mobile communication device or similar wireless device may be determined based on the data received from the cellular. In particular, the device's location can be determined by the cell number of the cell in which the device is using the same mesh and and possibly other data, such as movement.

The network works with the use of antennas, each of which transmits and receives signals from cellular devices located in a given area, called a cell. Square cells of different antennas overlap, thereby creating a full coverage area of the cellular network. At any given time, the mobile communication device is under the control of one of the cells of the network. Such a cell is typically one in which the intensity of the signal received from the mobile communication device, the greatest. When the mobile communication device moves, it moves from cell to cell and control of this device "jumps" from one cell to another.
For the cellular network and network management is necessary to control the many signals that come from mobile devices. Such signals may be, for example, the communication control signals, such as signals the beginning and the end of the connection, and signals re is eminii device, such as signals about the update location and the transition of control of the device to another cell. Next we use the description of the GSM technology, but in any appropriate case, we intend to refer also to other cellular technologies.
Use some or all of these signals, especially signals that are recorded on the "As-interface" (or "parallel" in some cell technologies), allows you to create an effective method of determining the location of the mobile communication device. Next, we will describe how to retrieve data about the location of the mobile communication device from the signals of the transfer of control over the mobile communication device, although this can be done for other signals that are recorded and can be monitored in more than one cell.
Although in the disclosed below, the preferred embodiments of implementing the present invention describes a rigid way of a change of control, such as networks based on GSM technology, principles and benefits of the present invention is also applicable to soft way of a change of control and for the combination of hard and soft methods. In this sense, the best way to get control is used in most systems 1G and 2G, when the device with a working link forwards from one radio cell operating on the ne pair of frequencies, to another radio cell operating on a different pair of frequencies while driving call. If the device can be connected to only one base station and, therefore, required to break the connection when it connects to another station, such a change of control refers to hard.
The technician will understand that systems based on CDMA technologies, including WCDMA technology, the user can be connected to multiple base stations simultaneously, the signals from all transmitters in the frequency range are combined in the RAKE receiver in one signal. The set of base stations for which simultaneous communication device, called the "active set" of stations. "Soft transition" occurs when there are multiple base stations in the active set of stations and the communication device is disconnected from one of the stations to connect to another station, or add a new station without disconnecting from the existing station from the active set of stations. In WCDMA technologies there is a special case, called "softer transition, when different connections to the stations of the active set of the stations are provided with the same base station. A softer transition occurs when one of these compounds disable to enable another on the same base is tanzihi. There are also methods which control is transferred between systems, in which the connection forwards from one access technology to another, such as call transfer from GSM to WCDMA. The principles of operation and advantages of the present invention is applicable to all the above types of control transfer and the claims should be interpreted in line with this, although the specific benefits and/or real benefits in each case, may vary slightly, that would be understandable to experts in this field of technology.
So, at any given point in time, the mobile communication device is under the control of one (GSM), or more cells of the network. Controlling the cell or cells are those receiving signal which is considered acceptable for control and signal transfer control to a new cell (or adding cells) will be called here the signal "change of control". Therefore, the signals which control is transferred reflect a snapshot of the situation (the exact time of appearance of these signals recorded), in which the cell phone is under the control of two or more cells when these cells receiving signals are of approximately equal size. This means that building a space where all these cells have approximately the same received signals, it is highly likely, is that the cell phone is located in this square.
For the explanation below described examples of preferred embodiments of the present invention in the case of exchange of signals between two cells in the network with GSM technology, but the same method can be applied in the case when more than two cells, for example, for the active set of cells in the network with CDMA technology, by applying the following principles and techniques to all these cells.
Often the signal of a change of control GSM network and similar networks, including cell a and cell B, occurs when the mobile communication device moves from the area where the intensity of the signal from the antenna of the cell, a higher than from the antenna of the cell, to the area where the intensity of the signal from the antenna of the cell is higher than from the antenna of the cell A. Therefore, theoretically, the change of control occurs at a time when the mobile communication device crosses the line signals of equal intensity of signals received from both cells. In practice, however, the transfer of control does not occur exactly on the line signals of equal intensity, and occurs within a certain area of the penumbra, which is located around the line signals of equal intensity. The shape and size of the area of the penumbra dependent on a number of indicators, including the relative location of used cells, and also depend on the position and orientation of the antennas.
In predpochtitelno embodiment, the present invention describes a method for determining with a high degree of certainty the geographical location of the mobile communication device at the moment when the transmission control device, by finding the "square of the change of control", which is a zone in which with high probability should be control over the mobile communication device as it moves from cell a to cell C. Since, as detected, the square of a change of control average less areas of cells, this method provides higher accuracy than a way to find the device only with regard to areas of cells. In addition, since the moments of change of control are recorded in the control system network, there is no additional cost, so this method is relatively inexpensive.
To implement the preferred option to build a polygon representing the transition zone of control. This made four simplifying assumptions.
First, made the simplifying assumption that the antenna pattern (square cell) is a sector with angle, basically, 120°, the center of which is the antenna, see, for example, sector 101, surrounding the antenna 100 in the embodiment shown in figure 1.
Secondly, made the simplifying assumption that, while the mobile communication device is within the sector, the intensity received from the antenna signals grows inversely proportional to R is the is from the antenna. Other factors affecting the intensity received from the antenna signals, such as the exact azimuth of the antenna, the presence of reflections and multi-channel are discarded, since the influence of these factors is limited and they are often statistically compensate each other.
The third simplifying assumption is that the intensity of the signal from the antenna on the outside of the sector receive significantly lower signal intensity from the antenna inside the sector receive.
Fourth simplifying assumption is that the transfer of control from one cell to another occurs at an acceptable distance from the point at which the mobile communication device receives signals of equal intensity from both antennas.
On the basis of these assumptions in the preferred embodiment of the present invention, the square of the received signal cells presents in the form of a sector with a limited radius. In areas outside this radius may be coming, but significantly weaker than in the area within the radius. In addition there are areas of weak received signal for the boundary lines of the sector, in the field behind the antenna and in opposite directions from the sector. In some cases, control of the mobile communication device can be made in these areas of weak signal reception. Therefore, in a preferred variant of the present invention, under certain circumstances, the area of reception cells can be expanded from the originally simulated the acquisition section in the direction of areas of weak reception. As soon as such circumstances are taken into account, the sector receiving the cells expand, thus resulting model square signal of the cell will be referred to as the effective area of the cell. As will be shown below, the extended size of the cell can be built taking into account the relative position and orientation of the two antennas between which moves the mobile communication device. For example, extensions can be made, when the antenna of one cell is located within a sector of another cell, but very close to the border sector of the device (as shown in the variant of figure 5), or when the antenna is one cell in a particular way is located outside the sector of another cell (as shown in the variant of figure 6). In these cases, the effective area of the cell contains extensions for border sector administration. In addition, in some cases, the radius of the acquisition section may be increased or decreased depending on the distance between the antennas of two cells, the resulting radius will be called "effective radius of the cell.
Taking into account the above considerations, in the preferred embodiment of the present invention shows a polygon that represents the area on which control is transferred in the form of a combination of two parts: 1) an overlapped part of the effective areas of the two cells between which moves the mobile communication device and 2) the area of the penumbra around the line of equal intensity in the space between the antennas of two cells. As will be shown below, the relative positions of the two cells plays a significant role in determining these two zones. There are cases where the area of the penumbra cannot be determined, thus take into account only the effective area of the cell.
Figure 1-4 shows four options relative position of the two cells in accordance with a preferred embodiment of the present invention. Figure 1 antenna of the first cell 101 and the second cell 102 is located at one point 100. In figure 2 the first cell 201, a display area signal, the first antenna 203, oriented toward the second cell 202, a display area signal of the second antenna 204, while the antenna of the two cells are located at various points and directed one towards the other. Figure 3 antenna 303 and 304 of the first 301 and second 302 cells are located at various points and their sector of reception do not overlap. Figure 4 shows an example that does not fit into variants relative position of figure 1 to 3 and displays all other possible options for the location of antennas; in this case, the antenna 403 and 404 are located at different points, at the same time they face each other at an acute angle, and the sectors 401 and 402 overlap.
The method of determining the geographic location of the mobile communication device according to a preferred variant implementation of this image is to be placed includes, first, the definition of the effective area of each cell, and secondly, the definition of the area of the penumbra around the line of equal intensity and, thirdly, the Union of the areas defined on the first and second stages, for finding the square of a change of control.
The first phase of the preferred alternative implementation of the present invention includes the determination of the effective area of each cell. In order to do this, first find the effective radius of the sector of the cell. The existence of such a radius based on the above second simplifying assumption, i.e. that the intensity of the received antenna signal within the sector receiving grows inversely proportional to the distance from the antenna. Determination of the effective radius of manufacture with regard to variant relative location: the location of option 1, in which the antennas are located on one and the same point 100, the effective radius is R1, 103. In other embodiments, shown in Fig.2-4, the effective radius is equal to Ri×D, where D is the distance between antennas, a Ri- constant coefficient, different for each case (i.e. for 2-4 index i=2, 3 and 4). In a preferred embodiment of the present invention can be used other ways to determine effective radius, including ways to the e establish the relationship of the distances between the antennas with an effective radius.
Next, after determining the effective radius of a sector of a cell are the effective area of the cell, in some cases extending the sector at its edges. The result is determined by the side line of the effective area of the cell. The expansion of the area of cells at the edge of the sector is required, for example, in two cases: 1) when one antenna is located in the sector of another cell, very close to its boundary lines, as shown in the variant of figure 5, and 2) when the antenna is located outside the sector of another cell, and the internal angle between the boundary line and the line connecting the two antennas is greater than 180°, as shown in the variants on figa and 6B.
In the first case, shown in figure 5, the angle β, 503 formed by line 505 between the two antennas 501 and 502 and one of the boundary lines 506 of the first sector is less than a predefined angle α, 504. Previously certain angle α is given as the angle within which the antenna 502 is located so close to the boundary line 506, in order to guarantee the expansion of the area of cells at the edge of the sector. When the angle β is less than the angle α, the sector expanded in one direction only, i.e. in the direction 506, which is located near the second antenna 502. To the side 506 sector is added to a small extend rectangle 508 width E1, 507.
In the second case described with reference to variant figa, the second antenna 602 location is and outside the sector 603 of the first antenna 601. In this case, determine whether the internal angle, i.e. the angle which includes the first sector 603 and is formed between the edge 607 or 608 sector line 603 and 609 between the two antennas 601 and 602, a large 180°. Then make an extension on the edge of the section 607 or 608, for which this condition is satisfied. For example, consider the edge 607 sector 603. The internal angle between the edge 607 and line 609 is the angle 605, and this angle 605 is greater than 180°. Accordingly, the edge 607 expanded on the rectangle 610. Similarly, considering the edge 608 sector 603, it is seen that the internal angle between the edge 608 and line 609 is the angle 606, and this angle 606 is greater than 180°. Accordingly, the edge 608 extended to the rectangle 611. In the second case, shown in figa and 6B extending rectangles, such as 610 and 611 may have a relatively large width E2, 613, than the width of the E1, 507 extends rectangle in a variant of figure 5. In addition, when in a given sector, there are two extends rectangle 610 and 611 for the antenna 601 form additional widening triangle 612 between the two farthest corner 623 and 624 extends rectangles, both of these extensions have the same width E2. It should be noted that while large expansion made the sector 603, because the antenna 602 is outside the bounds of the sector receive antenna 601 (and the criterion of the internal angle of udovletvor the tsya), the reverse situation can't be done for another sector. This is because in this case the sector 604 cannot be increased with the expansion of the second type, since the antenna 601 is inside the sector 604.
In a variant figa shows another example of the expansion of the second type, in which instead of two edges extend to a higher level (only one edge of the sector. In this case, the antenna 615 is positioned outside of the sector 616 antenna 614. However, the internal angle 622 between the edge 617 and line 620 is exactly equal to 180° (and, therefore, no more than 180°), so that the extension region 617 do not. On the contrary, the inner corner 621 between the edge line 618 and 620 is greater than 180°, therefore, the expansion 619 second type region 618.
Defining the effective area of the cell (in this preferred embodiment, by determining the effective radius and, in some cases, extending the edge of the sector), the second stage determines the area of the penumbra around the line of equal intensity signals between the two antennas, as shown in the embodiments 7 and 8. In this embodiment, the area of the penumbra around the line of equal intensity are presented in the form of asymmetric rectangular strips around the line of equal intensity. Width W1a rectangular strip between the line of equal intensity and border strips on the side of the cell, which includes at trojstvo cellular, greater than the width W2on the side of the cell from which the mobile communication device. For example, as shown in embodiment 7, the area of the penumbra around the line of equal intensity 710 is formed by two rectangular strips 706 and 707, the width W1, 708 strips 706 on the side of the sector 704, which includes the mobile communication device, is greater than width W2, 709 strips 707 on the side of the sector 705, which gives the mobile communication device. Each strip is formed between the line of equal intensity 710 and border strips 711 and 712. Similarly, as shown in option on Fig, the area of the penumbra around the line of equal intensity 808 is formed by two rectangular strips 806 and 807, and the width W1, 809 strips 806 on the side of the sector 805, which includes the mobile communication device, is greater than width W2, 810 strips on the side of the sector 805 exits the device provider.
For determining the size of the penumbra around the line of equal intensity in the preferred embodiment, the present invention should first determine the location of the lines of equal intensity, which varies depending on the relative position. In the first case, the relative position in option 1, which is a variant of Fig.7, the line is avnoj intensity represents the bisector 710 azimuth 702 and 703 of the cells (which are determined by the location of the antenna 701). In the second and third cases, the relative position in options 2 and 3 the line of equal intensity represents the perpendicular in the middle of the line connecting the two antennas. For example, for option Fig, which corresponds to the case of figure 2, the line of equal intensity represents the perpendicular 808 in the middle of the line 803 connecting the two antennas 801 and 802. In the fourth case, the relative position in option 4 points of equal intensity are difficult to determine, and strip similar to the strip 7 and 8, does not exist.
Defining the effective area of the cell and the area of the penumbra around the line of equal intensity, in the third step of this preferred option determines the area of the transition of control of the mobile communication device. For each case relative position, with the exception of option 4, for each cell at the intersection of the effective area of the cell and the area of the penumbra around the line of equal intensity form the zone in which such cell is potentially capable of transmission control. The area on which control is transferred when the movement of the mobile communication device from cell a to cell b displays by combining squares, in which two cells have the potential to provide for the transfer of control. For example, as shown in the variant of figure 9, the transition zone of control of the mobile communication device, d is iiusage from the cell And, 901 to the cell, 902, first determine the intersection of the effective area of the cell a and the rectangular strips 903 area of penumbra around the line of equal intensity 904, then at the intersection of the effective area of the cell and In rectangular strips 903, then combine these two areas, which are represented as the shaded area 905. Option Fig.9 shows the method of determining the square of a change of control during movement of the mobile communication device from the cell And to the cell In case of mutual arrangement according to the variant of figure 2, for which the defined rectangular strip 903. In the case of a mutual arrangement according to the variant of figure 4, for which such strip is not defined, the transition zone of control during movement of the mobile communication device from the cell And to the cell To determine the intersection of the effective areas of two cells, each of which may contain the above-described expansion of either the first or second type. For example, in the form of figure 10, the effective area of the sector 1001 was increased due to the expansion of the first type 1002, and the effective area of the sector 1003 was increased due to the extension 1004, 1005 and 1006 of the second type. Because this case relative position is similar to the case in embodiment 4, the area on which control is transferred when the movement of the mobile communication device from a cell 1001 to the cell 1003 is equal to the area of intersection of these two effective the areas shown shaded area 1007. It should be noted that the difference between the transition zone of control during the movement of the mobile communication device from cell a to cell b and the transition zone of control during the movement of the mobile communication device from cell to cell And depends on the degree of asymmetry of the square of the penumbra around the line of equal intensity, which occurs in cases of mutual arrangement of options 1-3.
As can be seen in the variant figure 10, the area of the change of control 1007, determined in accordance with the preferred embodiment of the present invention, much smaller than the effective area of the sectors receiving cells 1001 and 1003. Therefore, in General, the method of determining the location of the mobile communication device, in accordance with which define the transition zone of control according to a preferred variant implementation of the present invention is significantly more accurate than previously used methods, based on the determination of only the sectors receiving the cell that contains the device.
In a preferred embodiment of the present invention, the accuracy generally increases when the location of the mobile communication device using information about the movement of time in addition to information on the identification of cells. Figure 11 shows a circular sector 1101, which is used to simulate approximately what about the location of the device in this case in accordance with the preferred embodiment of the present invention. Information about the time of movement restricted area of the location of a mobile phone ring sector 1101 between two given radii 1102 and 1103, conducted from the point of location of the antenna 1104. It will be shown that using information about the time the motion or other information provided by the cellular network, which can narrow the simulated size of the cells can be partially used in the described preferred embodiments, for example, by converting models to determine the effective area of the cell. For example, in the preferred embodiment 11, the area of the cell can be represented in the form of an annular sector, which may be elongated, forming the effective area of the cell by the same method, which is described above. In a preferred embodiment of the present invention can be used as a cell of another form. Regardless of the form of the effective area of the method according to the preferred variant implementation of the present invention generally increases the accuracy of determining the location of the mobile communication device. For example, using a circular sector 11, it is possible to reduce the area of location of the device, even when using full sectors reception mentioned above.
Specialists in the art it will be clear that the main above-mentioned parameters (such as R 1, R2, R3, R4α, E1E2, W1and W2) can be determined empirically and calibrated in the field trials. For example, can be performed test measurements, when the actual location of the control devices cellular is known, so the actual location can be empirically consistent with the map cells to determine the required values of the parameters. Based on the pilot measurements can be carried out the statistical estimation of parameters, and these parameters can then be improved with the accumulation of test results and other data for some period of time. Can be used as another parameter. Moreover, it may be the selection of the above parameters or used fully other options. When you use cellular networks other than GSM technologies, such as network with CDMA technology, the preferred embodiments of the present invention can be modified, for example, so that the area of control transfer is modeled some form or set of forms, defined by the location of the cells in the active set of cells.
In accordance with a preferred embodiment of the present invention method and device location us the mobile communication device can be used as an element in the information system, analyzing traffic flows, such as the system described in U.S. patent 6587781 Feldman and others, a General block diagram of which is shown in the variant Fig. In this system, determine the location of each of the multiple mobile sensors in vehicles travelling on the transport network 12, which is then analyzed, forming a network oriented transport sectors 14. In addition to the signals from the mobile sensors can be used other sources of traffic information, and may not be used. For some time data 62 on the position of the sensors received from the mobile sensors are collected and processed in cumulative module 1, and then fed to the transmitter normalized time motion 2. Based on the collected data, the computer time traffic 2 determines the average of the normalized motion for each oriented transport network 14. The generator final and current picture of traffic flows 3 uses the calculated normalized values of time of the movement, as well as data obtained from other sensors, to build the current pattern of traffic flow on the road network. Then the predictor 4 can use the current picture of traffic flows and data generator 6 painting templates and rules adjust the salvage flows for predicting the pattern of traffic flows or to provide other information to the device control threads 5, which can have many uses 7. Generator final and current picture of traffic flows 3 to combine data from various sources, including from the solver normalized time motion 2, data traffic from the fixed sensors 60, the data of the transport stream of reports 64 and data traffic from other sources 66.
In accordance with a preferred embodiment of the present invention describes a device that implements the method of determining the location of cellular devices, can be used to obtain information about the transport stream using cellular devices located in vehicles. For example, when a specific device for cellular found the area of the transition system, analysis of traffic flows can take the area corresponding to the detected area as an estimate of the location of the vehicle, which is a mobile communication device at the time of the change of control. On the basis of the calculated position and time for a large number of such vehicles, and traffic flow data obtained from other sources, the evaluator normalized time motion 2 or other system element analysis of traffic flows, m which can create a picture of traffic flows for a large number of users, including the prediction of future traffic conditions movement. In one preferred variant of the described method of determining the geographical location of the cellular implemented using cumulative module 1 shown in Fig. For cumulative module 1 serves location data 62, which may include information about the moments of change of control received from the cellular network. Location data 62 may, for example, include information about the current time and the ID of the active cell and position data of the vehicle obtained from many other sources, such as GPS data and other changing data about the vehicle. Data on the location of the vehicle 62 from various types of sensors together on their own separate cumulative submodule (including cumulative module 1 Fig). Many of cumulative submodules can also be used for processing various data coming from the same mobile sensor. For example, a separate cumulative submodules can be used for data transfer control and data between a server about the location of the grid.

In this case, the square of the change of control for all possible combinations of neighboring cells can be determined on the basis of the map cells in an offline process and can be stored in a database that is available to the system corresponding to the present invention. When information about the cells fed to the system, the system uses the identifiers and/or data about the time the motion or other data for a specific case of a change of control in order to compare them with the data stored in the database (for example, using the summary tables), which receive a corresponding value of the square of the change of control. Thus, in the first example, the device 1305 is offline and the data 1300 consistently treated by comparison with the data of the change of control, created offline module 1303. On the contrary, in the second embodiment, in the system corresponding to the present invention, the map cell no is. Instead, the system enter the geographic coordinates of cells involved in each case of change of control, and calculate the square of a change of control in real time, receiving the data stream is used, for example, in the variant Fig. There is no need to display the modules 1301-1303 option Fig directly in the form of various software modules, instead, the software may have a different or more complex construction is functionally equivalent to the previous build, as it will be clear to experts in the given field of technology.
