Abstract

A method for the transmission of local information is disclosed. Local information on a region corresponding to the cells belonging to the base station is recorded for various base stations of a cellular mobile radio system. Said local information is at least partially sent to a terminal within a cell of a base station by the base station and rendered as output by the terminal. The current local information obtained thus can be used within a navigation process.

Method for the transmission of environmental information

The invention relates to a method for transmitting environmental information and a navigation method using this method. In addition, the invention relates to a terminal, a navigation device and a mobile radio network base station for performing the method.

In the currently commercially available navigation systems, for example navigation devices in motor vehicles, the cartographic information required for navigation is generally taken from a data memory of the device itself. The data memory is often an exchangeable data memory, for example cards on CD-ROM. Using this map material, the navigation device automatically determines the optimal route between an entered location and a destination. The current location of the vehicle is determined at any time via a location determination system, for example GPS, and a map section around the location is shown on a display, the location being marked within the map section. In addition, the direction of travel to be taken is indicated by a corresponding voice output or by arrows on the display. A disadvantage of this method is that the map material is not up to date. In order to be reasonably up to date, updates have to be carried out regularly or new CD-ROM cards have to be purchased. Nevertheless, short-term changes in traffic routing, such as closures due to construction sites, accidents or traffic jams, are inevitably not detectable, which can lead to incorrect planning when optimizing the route.

It is an object of the present invention to provide a method by which a user can easily update current location information about his current location. can be taken care of. On the one hand, this method should serve to provide the respective user with ^simple and inexpensive information, for example for navigation aid for pedestrians or the like. In addition, the method should also only be usable for carrying out or optimizing navigation methods

This object is achieved by a method according to claim 1.

According to the invention, environmental information relating to an area which is adapted to the cell belonging to the base station is stored for different base stations of a cellular mobile radio system. The term “cell *” here means the transmission / reception range of the respective base station.

The cellular mobile radio system can be any mobile radio system, for example according to a GSM, UMTS or DECT standard.

The environmental information is preferably cartographic information. In principle, however, it can also be other environmental information, for example information about sights, leisure facilities or the like. Of course, it can also be a mixture of different information, i. H. act cartographic and additional information.

This environmental information is at least partially sent from the base station to a terminal located in the respective cell and output by the terminal. The output can be made either directly to the user, for example by means of voice output or via a display. However, it can also be an output to other devices, for example to a motor vehicle navigation device connected via an interface. The adjustment of the area available on the station for the respective base ^¬ information to the respective cell, can be done so that the area of cover and the cell match the same. However, the area is expediently somewhat larger than the corresponding cell, so that end devices which are located at the edge of the cell also receive information about their entire environment within a certain surrounding area and not only around a surrounding area in the direction of the respective base station who is currently connected. Of course, it is also possible that the area is smaller than the respective cell, that is to say that no environmental information is made available for certain areas within the cell, for example. The term "adaptation * of the area to the

Although cell therefore preferably includes the identical correspondence between cell and information area or a definition of the information area with a certain edge coverage outside the cell, in the broadest sense this term encompasses any adaptation to the cell, taking into account further parameters.

The environment information for the individual base stations can be stored centrally in a special facility in the mobile radio network and can be called up by the base stations as required. In order to minimize the data flow within the network, however, it makes sense if the environmental information is stored locally at the individual base stations. Another alternative is to store the data in the so-called “base station controller * (BSC), which control several base stations (also called“ base transceiver station * (BTS) in the GSM system). This saves storage facilities and still reduces the data flow within the mobile radio system. Storage in a so-called "Mobile Switching Center * (MSC) is of course also possible. possible, which in turn controls several BSCs, so that regionally centralized storage takes place.

The location of the terminal is preferably determined by the mobile radio system and / or by the terminal.

This location can be determined, for example, by a GPS module in the terminal itself. It is also possible to use the so-called "differential GPS *" to improve location determination, in which the base stations themselves also receive the GPS signal and compare it with the actual coordinates of the base station, and as a correction value the difference between the actual location of the base station and the base station location of the base station determined by GPS is transmitted to the terminal.

With relatively small cells in particular, it can be used to achieve a very good accuracy in determining the location. This correction data can be immediately transmitted with the environmental information.

A determination by the mobile radio system itself is also possible, for example by means of the “timing advance * method, in which information about the distance of the terminal from the base station or from different base stations of the mobile radio network is determined on the basis of the transit times.

The environmental information is preferably adapted before being sent from the base station to the terminal and / or before being output by the terminal to the location. Adjustments to the requirements of the user or the time of transmission are also possible.

When sending cartographic information, for example, a selection in the sense of selecting a suitable map section around the respective location is useful. In this case, the adaptation can also be an adaptation of the scale, ie the resolution of the map, >> f N> P ¹ no Cπ O Üi O Cn ^' ω α ro PJ N 3 tr ω Λ ü σ α c s. cn Hi cn et CΛ N £ 3 cn öd P> ö O: ϊ ^ Φ 0 cn H d

on the one hand a completely new representation of the Informatio ^¬ NEN conceivable as well as an overlapping view with elements of the respective neighboring cells. Such automatic ^¬ specific adjustment during a movement of the terminal within a cell or across cells may of course also for other environmental information, as for kartografi- specific information, are performed.

Preferably, in particular when the method is used as a navigation aid or within a complete navigation method with path determination, the spatial orientation of the terminal is additionally determined by the mobile radio system and / or by the terminal. For this purpose, for example, the terminal has a corresponding device for determining the spatial orientation. Spatial orientation is primarily to be understood as the direction in which the terminal is oriented. In the simplest case, the terminal has a magnetic field measuring device, for example a Hall probe, or another suitable electronic compass. The spatial orientation can then be output together with the environmental information. Likewise, the environmental information that is output can also be adapted to the spatial orientation of the terminal. When a map section is output, this map section can, for example, always be automatically tracked on the display according to the respective actual viewing direction, so that the information in the direction of the upper edge of the display of the terminal device is always directly in front of the viewer.

The use of a commercially available mobile radio device, which is preferably equipped with a few additional devices, for example a device for determining the location or for aligning the device, is suitable as the terminal device. All other essential components, such as a corresponding graphic display, a voice output,

which information is stored in the base station 2 is somewhat larger in the present exemplary embodiment than the associated cell 11, so that a mobile radio device 5, which, as shown, is located in the edge region of the cell 11, still contains information within a predetermined radius around the mobile radio device 5 receives and not only information from an area in the direction of the base station 2. The other base stations 1, 3 naturally also contain information from corresponding areas about their cells 10, 12.

If a mobile radio device 5 is located within the cell 10, 11, 12 of a base station 1, 2, 3, - in the exemplary embodiment shown in the cell 11 of the central base station 2 -, the required environmental information is automatically sent from the base station 2 concerned to the mobile radio device 5 Posted. In the present exemplary embodiment, the environmental information is cartographic information.

The base station 2 expediently does not send all of the available information to the mobile radio device 5, but rather only a map section in an area 9 around the current location of the mobile radio device 5. This minimizes the data flow. Of course, this requires that the location of the mobile radio device 5 of the base station 2 is known.

This location determination can be determined in the terminal 5, for example with the aid of a GPS module or the like. The accuracy of the location determination can be increased to less than 1 m by transmitting a GPS correction signal from the base station 2 to the mobile radio device.

If the mobile device itself not equipped with means for determining its own site, can be achieved using "Timing Advance ^* in the GSM system the removal of Endge- cυ cυ IV) IV) P ¹ P>

cut from the surrounding area 9 of the mobile device 5 to the mobile device 5 currently transmitted. In this map section, the distance circle - or the corresponding section of the circle within the map section - is also displayed, so that the user can correct his position again and again and thus the map is tracked according to the movement of the user with the mobile radio device 5. This tracking is of course carried out automatically in a mobile radio device 5 with automatic exact location determination.

In addition, the mobile device 5 has a Hall probe (not shown) with which the orientation of the mobile device, i. H. the cardinal direction in which the user is looking is determined. On the basis of this information, the map on the display is automatically tracked in the respective actual viewing direction, so that the information in the direction of the upper edge of the display 6 is always directly in front of the user. The user can e.g. B. as a pedestrian in unknown surroundings, for example in the inner city area, always be informed about which direction he has to go, even in the dark and without having to pay attention to certain features such as street signs or buildings.

When the mobile radio device 5 moves from one cell 10, 11, 12 into another, it is automatically transferred to the corresponding base station 1, 2, 3, the surrounding information then automatically being supplied by this new base station 1, 2, 3. Such a “hand over *” also takes place during the transition from a base station of one BSS to a base station of another BSS, this transition being managed by the respective BSCs, which - as shown in the figure by the double arrow - are connected to the network.

In an exemplary embodiment not shown, the mobile radio device 5 is used for navigation in a motor vehicle. applies. For this purpose, the motor vehicle has a navigation device which is connected to the standard interface of a car kit which is already in the motor vehicle for hands-free operation. This navigation device consists primarily of a voice input / output system for input and output of the start and destination coordinates, a larger separate display and the connection to the car kit. Via the interface or the other components such as the microphone, loudspeaker, amplifier, DSP of the car kit, when the mobile radio device is plugged in, the user has an extremely inexpensive but at the same time comfortable navigation system which constantly delivers current data. In particular, the navigation device can react very quickly to construction work in the street area, to accidents or traffic jams in the area of the cells passed through. On request or automatically, information can be requested in advance from other base stations along the planned route via the mobile radio network, in order to be able to bypass the area concerned in the event of short-term obstacles.
