Description

The The present invention relates to the location of mobile telephones or mobile stations in mobile networks, in particular in emergency situations.

The Localization of mobile phones, especially if they are not over a built-in GPS receiver (GPS = Global Positioning System) or there is no GPS coverage, takes place in the conventional technique by evaluating the information, by the connection of the mobile phones to the mobile network and its network infrastructure can be gained. In the field of conventional technology, localization can be due to Evaluation of a position of a transmitting mast of a radio cell made in which a mobile phone is registered. Some radio cells are characterized by sectorized antennas, in which Cases the virtual center of a sector as the position of the Mobile phones can be specified in which the mobile phone is booked.

These Approach allows a position determination of a mobile phone, or a mobile terminal, only with a limited Accuracy. This is particularly disadvantageous in situations where Emergencies occur and a timely arrival of rescue workers is essential.

In the 6 a communication scenario in an emergency situation is shown as an example. The 6 shows the use of a localization service as an example of alerting emergency services. In the 6 is a mobile phone 610 (MS = mobile station), from which an emergency call (Emergency Call) is sent, which is transmitted via a wireless mobile network (PLM Network = Public Land Mobile Network). 620 and a wired network 630 that can be implemented by a POTS network (POTS = Plain Old Telephone Service or Post Office Telephone Service) or an ISDN network (ISDN = Integrated Services Digital Network) to a rescue center 640 (Emergency Center). By using previous conventional location services of a network operator 650 (PLMN operator), is a location information (Location Information from LBS, Location Based Services LBS) to an information center 660 (IT Center, IT Information Technology) passed through a suitable software of the rescue center 640 the calculated position of the mobile phone 610 Show on a map (Location to Map), so that the rescue services can be directed to the right place.

One Disadvantage of the previous solution is the only limited Accuracy with which the position of a mobile phone or mobile terminal can be determined so that there are delays in Use of rescue services comes, and this is precisely in the Serious consequences in the field of emergencies can pull.

The DE 10345224 discloses a method for estimating the position of a subscriber station of a radio communication system in which a receiving station receives reports from the subscriber station, each containing information regarding a signal strength of a received signal from at least one transmitting station at the subscriber station location. The reports are stored in a memory of a network device of the radio communication system and a position determination takes into account at least two reports on the position estimation of the subscriber station stored before the request for position estimation. The position of the subscriber station can then be determined by comparing the signal strengths with a signal strength database. The described method has the disadvantage that the position of the subscriber station can only be determined as accurately as the resolution of the database permits. In addition, the database must be measured and stored and updated as the network expands. A position determination is thus only inaccurately possible.

The WO 98/15149 discloses a method for determining the position of a mobile station in a cellular network. A network management system receives information from a mobile station about field strength measurements made by the mobile station. In a next step, the field strength measurements are compared with a field strength matrix, and the position of the mobile station, based on the coordinates of the field strength matrix, at least in relation to the base station at which the mobile station is registered and another base station estimated. The field strength measurement of the mobile station is adapted as exactly as possible to the field strength information in the field strength matrix. The method described here has the disadvantage that the position can only be determined inaccurately, since in the field strength matrix only values are present at specific locations, which were determined by a measurement. Furthermore, the method described has the disadvantage that the update of the field strength matrix generates additional expense.

It is the object of the present invention to provide a more accurate and improved determination of a Po tion of a mobile terminal, especially in emergency situations.

The method further includes a step of transmitting additional information to the transceiver when additional localization data is needed and a step of determining the position of the transceiver based on the localization data or the additional ones Localization data.

The core idea of the present invention is that a transceiver can detect a large amount of radio data that is useful for determining a position. For example, it is possible to perform measurements on base stations in various mobile radio networks, such as in GSM (Global System for Mobile Communications) networks, UMTS (Universal Mobile Telecommunication System) networks, on WLAN hotspots (WLAN = Wireless Local Area Network) or to Bluetooth transceivers. Embodiments of the present invention prioritize captured data, such as field strengths, signal propagation delays, attenuations, path losses, absolute and relative location coordinates, etc. In this case, such radio data are prioritized, which allow a more accurate determination of the position of a transmitting / receiving device. This is particularly advantageous in emergency situations, since then an accurate determination of the position is necessary to rescuers as quickly as possible to the Place of emergency.

embodiments The present invention is therefore designed to provide readings to capture their own mobile network, as well as such other mobile networks, for example, at other frequencies are active or use other wireless technologies. These dates are then either automatically or initiated by a participant to an information center, which then transmits the data evaluates. For example, a presumptuous Wi-Fi hotspot or its IP address, and the information center would then be able to reference the location of this Wi-Fi hotspot to identify the IP address. In this embodiment could be due to the low range of the Wi-Fi hotspot the location of the transmitter / receiver device relatively accurately be determined. Is the information center unable to To identify locations of transmitted stations, for example because none There is a possibility to assign a specific IP address Place or assign data from stations with unknown locations the information center has the option Request additional localization data from the transceiver, or new prioritizations to the transmitting / receiving device to convey.

For example In embodiments, a transmitter with less Range assigned a higher priority. It But it is also conceivable that in some scenarios a transmitter with a higher range is preferred when this transmitter z. B. is able to perform a more accurate position determination as another transmitter with a smaller range, for example through implemented concepts for runtime measurement or direction determination o.

It is also conceivable in further embodiments that the transceiver, for example via Bluetooth establishes a connection with another transceiver, which has, for example, a GPS receiver and can tell their exact coordinates. Due to the short range the Bluetooth connection, would be at a corresponding transmission These coordinates to the information center a very accurate localization the transmitting / receiving device possible. The localization data would then also information about the direct Include location coordinates.

In Embodiments of the present invention has the information center therefore about information about several network topologies from different operators, different Access technologies and wireless technologies, and possibly over Information additional stationary or too mobile terrestrial transmitter. In a further embodiment it would be conceivable to detect toll bridges, and in an emergency based on the toll bridges already passed to determine a section of motorway in which the distress call is sent has been.

In Embodiments of the present invention will be the location data determined by the transceiver were transmitted via a data link to the Information Center. This data connection can, for example, via a short message or realized over several short messages. has the transceiver, for example, accessing a WLAN hotspot or is already using the Internet over another technology connected, so would be a transmission over the Internet, so the World Wide Web (www = World Wide Web), conceivable. Furthermore, it is conceivable that the transmitting / receiving device via other transceiver an ad hoc network or a Multi-hop network is built to capture both localization data as well as to convey.

As a base station or base station transceiver generally becomes one Radio station called either stuck in a network infrastructure is installed or at least has a known position and can communicate with a mobile station. In the In the embodiments described below, a Base station or a base station transceiver also be realized by a mobile station, if its Position is known. For example, this could be a mobile station be that has an integrated GPS receiver or communicates with such in his vicinity, z. In a motor vehicle.

The 1a shows a block diagram of an embodiment of a transceiver 100 for communication in a mobile network.

Furthermore, the transmitting / receiving device comprises 100 An institution 120 for providing prioritization information for the transmitter of the mobile radio network and the at least one further transmitter, wherein the prioritization information is arranged such that a higher priority is assigned for a transmitter which permits a more accurate localization of the transmitter / receiver device 100 allows for a more inaccurate location of the transceiver as compared to a transmitter 100 allowed. The transceiver 100 also includes a device 130 for selecting location data of the transmitter having a higher priority, and further comprising means 140 to send the location data or a location determined by the location data.

In embodiments of the present invention, the device 110 be designed to detect the signals to detect signals from a mobile network or from multiple mobile networks. These signals can come from mobile networks of different frequency and also different access technologies, such as from GSM networks, UMTS networks, WLAN emergency spots or Bluetooth transceivers. Furthermore, the device 110 for detecting the signals to detect signal propagation delays or signal propagation time differences.

Specifically, the device can 110 be formed for detecting the signals in embodiments, a signal according to a reception level, a signal propagation time, a field strength or attenuation between the transceiver 100 and to detect the transmitter or the further transmitter. Furthermore, the transmitting / receiving device 100 An institution 110 for detecting signals adapted to detect signals from other transceivers that implicitly or explicitly contain location information. In embodiments of the present invention, the device 120 be provided for providing the prioritization information to assign a higher priority to a transmitter with a shorter range compared to a transmitter with a long range. In other scenarios, for example if a transmitter or a base station transceiver has special concepts for position determination, transit time measurement or direction determination, it is also possible to prefer a transmitter with a higher range to a transmitter with a shorter range, provided by this transmitter or with the help of the signals of this transmitter, the position of the transmitting / receiving device 100 can be determined more accurately.

Furthermore, the device 120 for providing the prioritization information to obtain additional information having prioritization information, wherein the transceiver device 100 further comprising means for receiving additional information. This can be particularly advantageous in emergencies, since a transmitting / receiving device could, for example, transmit localization data from transmitters to an information center whose position is unknown to the information center. In this way, an information center is given the ability to exclude these transmitters from the location data, thus eventually obtaining localization data that enables accurate location determination.

In another embodiment, the data connection is realized via a short message or several short messages.

1b shows a block diagram of an embodiment of an information center 150 , The information center 150 serves to determine a position of a transceiver based on location data. The information center 150 includes a device 160 for receiving the location data, and further means 170 to check if additional location data is needed, the means for checking 160 is designed to perform a localization attempt with the location data and to decide, if the location attempt fails, that additional location data is needed.

This may be very important, especially in an emergency, when a transceiver transmits location data that theoretically permits accurate location of the transceiver but positions of the transmitters referenced in the location data are not known to the information center. In this case, the information center has the possibility to transmit a message to the transceiver and to exclude transmitters with unknown locations from the location data. This can for example also be done via a short message, in which case the device 180 is adapted to transmit to transmit the additional information via a short message via the transceiver. Furthermore, in one embodiment, the means for transmitting 180 be configured to send prioritization information having information about unknown stations or information about stations with available positions.

2 shows a schematic representation of a system 200. for alerting rescue services according to an embodiment of the present invention. As already on the basis of 6 described initiates a mobile station 210 an emergency call (emergency call) in his home network 220 , which exemplifies here as a GSM network 220 is accepted. Principi piell are instead of the home network 220 Other networks conceivable in which the mobile terminal, for example, in the context of a roaming agreement or via IP (IP = Internet Protocol) can be involved.

In addition to the established emergency call (emergency call) sends the mobile phone or mobile terminal 210 Data from, for example in the form of a message that contains the values described above and can be implemented via an SMS (Emergency SMS). The emergency call of the mobile station 210 is then from their home network 220 , or the network into which the mobile station is subscribed, for example via another network 230 , for example, POTS or ISDN, to a rescue center 240 (Emergency Center) forwarded. The from the mobile station 210 Sent message (Emergency SMS) is sent over a data connection to the home network 220 transmitted. This message may include, for example, one or more text messages (SMS) that are then sent from the home network 220 via the home network operator 250 and optionally via a suitable transceiver 260 (Modem) to an information center 270 is or will be forwarded. The Information Center (IT Center) has information in a database about the network infrastructure of the home network 220 as well as infrastructures of other networks, those of others Operated by network operators, which may also be realized through other technologies. The database in the information center is regularly updated in one embodiment by the various network operators.

The information from the database is evaluated using the information transmitted, for example, by means of a short message, the position can then be determined and on a map of the rescue center 240 being represented. The mobile station may be initiated automatically or by the subscriber, before or after an emergency call Einbuchvor make at different base station transceivers of one or from different network operators, which are possible in emergency and this to improve the accuracy of the positioning of the mobile terminal available put. Furthermore, in another embodiment of the present invention, the mobile station may be configured to log into one or more UMTS networks if possible, as well as to gather information about other networks, such as WLAN emergency spots. The mobile radio terminal can also collect information about the respective network infrastructure, for example by storing information over a certain period of time.

there can the mobile station then transmit such values, which come from the near past and can give information about Positions where the mobile phone is about to call has found. A limitation of the amount of these values is not according to the invention given, but given with regard to a simple realization. For example, it would be conceivable that a mobile radio terminal, that is capable of using bluetooth, for example Connect to another mobile device, that has its exact position and this in the case of an emergency call it is conceivable that the mobile terminal due to the limited Range of the Bluetooth connection directly to these coordinates transmitted the information center.

The transmission the information to a network operator independent information center has the advantage of having the information of different network operators can be exploited for position determination. It leaves thus an increased accuracy of the position determination achieve more information about network environments and also various network infrastructures available stand as a conventional, only one Network infrastructure based positioning would be the case.

Alternatively, however, the determination of the information may also be by the network operator 250 be taken over, as exemplified in the 3 is shown. The 3 shows a similar scenario as already based on the 2 has been described, wherein like components have the same reference numerals. The difference of the scenario in 3 compared to the scenario that in 2 is shown, that is now the network operator 250 who already has information about his own network infrastructure 220 has, the incoming message of the mobile station 210 evaluates itself and, for example, via Location Based Services (LBS) can provide a more specific position than was previously the case. In this embodiment, it is then assumed that the network operator has access to multiple networks or operates multiple networks, that of the mobile station 210 be able to evaluate transmitted information accordingly.

Embodiments of the present invention use for determining the position of a mobile station, information that is known to the mobile station, or can be determined by these and are transmitted to a suitable location that go beyond the information of the conventional localization method. The information that is used in embodiments for determining the position of a mobile radio terminal may, for example, also include a value of a timing advance in GSM networks and TDD UMTS networks. The value of the timing advance (TA) in GSM networks is a measure of the transit time of the signal from a base station transceiver or BTS (BTS = Base Transceiver Station) to a mobile station and back to the BTS in whole bit periods T _b , where rounded to whole bit periods. With 156.25 bits in a time slot of 15/26 ms, the bit period is increased

It is assumed that the effective distance between a base station transceiver and a mobile station is d, with the bit period T _b and the speed of light c = 3 × 10 ⁸ m / s for TA

The square bracket [] means here that is rounded to integers. Conversely, TA can be the effective distance d ≈ (TA + 0.5) · 554 m (3) to calculate. In the case of GSM networks, the inaccuracy of TA quantification is about 277 m. For a timing advance of TA = 1, for example, it follows that the mobile station is at a distance d of about 277 m <d <831 m from the base station transceiver. These values are influenced, for example, by reflections and diffractions of the electromagnetic waves, for example, the path of an electromagnetic wave can be greater than the actual distance between a mobile station and a BTS corresponds, so that the distance d in the example considered also slightly smaller than 277 m can be.

In TDD UMTS networks, a similar value is determined. The transit time of the radio signals between a base station transceiver in FDD UMTS networks into which a mobile station is registered may be determined, for example, by the following method. The base station transceiver transmits a first radio signal and notes when the first radio signal was sent. The mobile station typically receives a plurality of echoes caused by multipath propagation at different times from this first radio signal. The mobile station sends after a certain time t _TX-RX an acknowledgment to the base station transceiver. This period, which is between the time of receipt of the first echo of the first radio signal to the time of sending a reference signal value of the acknowledgment can be measured. The acknowledgment may then contain information about the value of t _TX-RX . The base station transceiver now receives the radio signal of the acknowledgment by, as a rule, a plurality of echoes caused by multipath propagation at different times. The base station transceiver can now determine the time difference between the receipt of the first echo of the reference signal value and the transmission of the original first radio signal. The double transit time of the radio signals can be determined by subtracting t _TX-RX . Furthermore, in embodiments of the present invention, the duration of the radio signals of the mobile stations can be communicated by a further radio signal, so that this then the mobile station is present.

Embodiments of the present invention take into account received level measurements for determining the position of a mobile radio terminal. For example, signal strengths received in GSM networks in the mobile station, referred to as "RXLEV", are measured by up to seven base station transceivers (BTS). These signal strengths are present in the mobile radio terminal as quantified values and are also referred to as RSSI (receiver signal strength indicator). With the logarithmic size p e / dBm = 10 · lg (P e / mW) (4) the received signal power P _e , applies to the relationship between signal power and RSSI

The open bracket ⌈⌉ indicates that the value in it should be rounded up. For example, at RSSI = 62, the logarithmic reception power p _{e of} the control channel BCCH (BCCH = Broadcast Control Channel) of a serving base station transceiver is in a range between -47 dBm <p _e ≤ -46 dBm. In the case of an equally distributed probability, the expected value of the logarithmic reception power at p _e = -46.5 dBm is to be assumed in this case.

The 4 shows an example of an association between receive services and RSSI, wherein in the 4 on the abscissa the RSSI values are plotted and on the ordinate the logarithmic received power p _e in dB. The 4 shows a linear assignment using the scales described.

wobei die g_i,x, g_{i , y} die Gewichtungsfaktoren für die x- und y-Koordinaten eines i-ten Basisstations-Sende-Empfängers sind. Die Gewichtungsfaktoren können in einem Ausführungsbeispiel beispielsweise in dem Informationszentrum aus den von dem Mobilfunkendgerät ermittelten und übertragenen Daten bestimmt werden.On the basis of the known values, a position, for example after two spatial directions x and y (x _MS , y _MS ) of the mobile station, are determined from the coordinates of the base station (x _BTSi , y _BTSi ) as follows,

where the g _{i, x} , g _{i , y are} the weighting factors for the x and y coordinates of an ith base station transceiver. In one exemplary embodiment, the weighting factors can be determined, for example, in the information center from the data determined and transmitted by the mobile radio terminal.

In one embodiment, the weights g _{i, x} = g _{i, y} . In other embodiments, for example when the mobile station provides data from regions at the boundaries of an area of a network operator or z. B. on coasts, etc., the weighting factors of the individual spatial directions can also be chosen differently.

In a further embodiment, all weighting factors g _{i, x} , g _{i , x} are chosen equal. Thus, the center of gravity established by the base station transceivers is determined to be g _{i, x} = g _{i, y} = 1.

In a further exemplary embodiment, the weighting factors g _{i , x} , g _{i, y are selected,} for example, in the order of the reception levels or reception powers downwards with constant differences between the individual weightings. 5 shows an example of such an embodiment, in which it is assumed that reception levels of 7 base station transceivers are present. The table in the 5 shows on the left side the number of the base station transceiver sorted down according to the received power or the receiving level and in the right column the associated weighting factors. According to the invention, a transceiver selects those seven base station transceivers which allow the most accurate determination of the position of the transceiver.

In In another embodiment, the weighting factors also directly from the measured reception power or reception levels be determined. Depending on the underlying propagation model, means a change in received power by 1 dB a change the distance between base station transceivers and Mobile terminal by a factor of 1.06 to 1.13. The propagation model and thus also this factor can adapt to the respective scenario be adjusted accordingly. The weighting factors of the weaker receivable base station transceivers then become reduced by the same amount as their receive levels.

Under in reference to a propagation model, can be derived from it obtained predictions for the reception levels in the environment the base station transceiver probability densities determine with which a mobile terminal to a certain place. From superposition of probability densities the individual, receivable by the mobile station Base station transceivers, the sought position the mobile terminal determined in another embodiment become.

If the mobile station or the mobile station information about in the past, can provide for every previous time, for the reception level measurements be present, the position of the mobile station to be determined. Because of the expected low speed of movement of a mobile terminal the true positions of temporally adjacent received level measurements do not become far apart. By a suitable averaging the calculated positions, taking into account the Determining a movement speed can be the true position in a further embodiment in more detail detect as if only one set of receive level measurements at a time is evaluated.

Other embodiments achieve an additional increase in accuracy if only a position determination is made relative to a known position for which corresponding receive level measurements of the mobile station are present. Optionally, the mobile station in a such embodiment also transmit receive level changes, as already mentioned above.

embodiments The present invention thus offers the advantage that a position a mobile terminal within the mobile networks can be determined more precisely, and thus create in particular an emergency situation the benefit of having rescue workers get to their place of work faster.

Especially It is noted that depending on the circumstances the inventive scheme also implemented in software can be. The implementation can be done on a digital storage medium, in particular a floppy disk, a CD or a DVD with electronic readable control signals, the so with a programmable Computer system can interact that the appropriate Procedure is performed. Generally, the invention consists thus also in a computer program product with on a machine-readable Carrier stored program code to carry out the inventive method, when the computer program product runs on a computer. In other words, Thus, the invention can be considered as a computer program with a program code to implement the method, if the computer program product runs on a computer.
