Description

MOBILE TELEPHONE FOR PARTNER SEARCH

The invention relates to a cell phone or mobile radio for making contact and in particular a cell phone which is suitable for initiating private and business contacts.

Mobile radio networks enable users to use wireless telecommunications both within limited zones and nationally and internationally. In contrast to conventional radio devices, conventional cell phones do not have a direct wireless connection between the transmitter and receiver, but rather they communicate with one another via a network of stationary base stations.

Figure 1 shows schematically the structure of a digital radio network according to the prior art. The user of a mobile radio device connects to other mobile stations MS or via gateways to subscribers in the public telephone network. A base station system BSS establishes the radio connections from and to the mobile stations MS. The base stations BS are connected to their own digital dial-up network, the so-called switching subsystem SSS (switching sub system). Dialing switching takes place in the switching centers MSSC (mobile services switching center). A communication link between two mobile stations MS is established via radio to the next base station, on lines via the switching subsystem to the base station BS of the called subscriber and from there via radio to the called subscriber.

A radio connection between a stationary transmitter and the mobile telephone or mobile phone is guaranteed at all times. For weight reasons, cell phones are equipped with small batteries, so that they have a limited transmission range. For this reason, mobile radio systems have a cellular structure, as can be seen in FIG. The geographical area Before it is distributed into individual mobile radio cells, each with a base station BS. Since only a limited transmission range is available for mobile radio, several participants share one channel. The cell radii of modern mobile radio networks, which are designed for car telephones, are a maximum of 30 to 35 km in the area with little traffic and around 2 km in the area with high traffic, such as in big cities and industrial zones.

Demands for the usability of mobile devices in all countries as well as for better voice quality and security against eavesdropping led to the introduction of the digital DEN network, which operates according to the GSM standard (global systems for mobile communications) in the frequency range of around 900 MHz.

The E-plus network works according to the DS-1800 standard, which leads to a shorter range at a frequency range of 1800 MHz with the same transmission power as GSM, with the maximum cell radius being around 8 km. As a result, the mobile phones manage with a relatively low transmission power. The E-plus network thus enables the use of small and light mobile phones with long talk and standby times and a high network capacity.

As can be seen from FIG. 2, the base station system BSS consists of a base radio station BTS (base transceiver station), a base station control BSC (base station control), ie a transmitter control and a transcoding device TCE (transcoding equipment), which carries out signal adaptation and transmission control. The base station controller BSC is connected to its transmitters BTS as a star network. The switching centers MSC together form a mesh-like network. Figure 3 shows schematically the transmission in a D radio network in different frequency bands when using TDMA data frames in different time slots according to the prior art. The D radio networks use the frequency ranges from 890 MHz to 960 MHz. Data is transmitted from the mobile station MS to the base radio station BTS in a lower frequency band. The data transmission from the base station BTS to the mobile radio devices takes place in an upper frequency band. The respective frequency bandwidth in the upper and lower frequency band of 25 MHz is divided into 124 transmission channels, so that each data transmission channel has a bandwidth of 200 KHz. Each data transmission channel is divided into 8 time slots, each of which has a duration of 0.577 ms. A time slot corresponds to an active data transmission connection. The time division multiplex method used is called TDMA method (time division multiple access). The data bits shown in Figure 3 are transmitted in a time slot TS. The transmitted data bits comprise 2x57 bits of useful information data, so that the useful bit rate is 24.7 kbit per second. The information of the radio subscriber is additionally encrypted using a complex security procedure, so that the net user bit rate of the radio subscriber is approximately 13 kbit per second.

Figure 4 shows the circuitry structure of a mobile station MS or a cell phone according to the prior art. The mobile station MS is a transceiver with a transmitter for sending a voice signal and with a receiver for receiving a voice signal. The analog acoustic speech signal spoken by the user into a microphone is converted into an electrical speech signal by the microphone. The downstream analog / digital converter converts the analog electrical voice signal into a digital voice signal. The generated by the analog / digital converter 13 kbit per second of user data is channel-coded via a channel coding circuit, the bit rate being increased to 22.8 KB by the introduction of additional security bits (block security, error detection and correction, parity codes). These are functions of the layer 1 protocol for transmission security. Then additional bits for the connection access protocol, for synchronization and for the transmission of messages (MTP: method transfer part) are introduced, so that the bit rate in front of the multiplexer increases to 33.9 kbit / sec. These are functions of the layer 2 protocol for data backup. The base station BSC controls which time slot TS the subscriber is assigned by the multiplexer and which data transmission channel the transmitter and receiver are matched to. The digital transmission signal is modulated and transmitted to the base station BTS by an HF transmitter via an antenna A with the lower frequency band.

Conversely, a received high-frequency analog voice signal is demodulated and accordingly supplied to the channel decoding circuit by the control signal TS. The received digital useful signal with a data transmission rate of 13 kbit / sec is converted by a digital / analog converter into an analog electrical signal which excites a loudspeaker which emits an acoustic reception signal to the user's ear.

As can be seen from FIG. 4, a cell phone or a mobile station MS according to the prior art has an HF transmitter device for transmitting a modulated transmission signal via antenna A and an HF receiving device for receiving a modulated reception signal via antenna A. on. A conventional cell phone or an ordinary mobile station MS is therefore a mobile radio with a transmitting and receiving device.

So far, conventional cell phones have only been used to set up FULL duplex voice transmission connections between two subscribers or to transmit SMS messages. The transfer of image data is also possible with some cell phones according to the prior art. Contacting a subscriber is only possible with a cell phone according to the state of the art if you know and dial its cell phone number.

In very many situations, however, it is desirable to establish a private or business contact with mobile phone users whose mobile phone number is not known, but who corresponded to a specific demand profile.

A typical situation is, for example, when the mobile phone user is in a holiday club and is looking for another person who has common interests or hobbies. For example, if you are looking for another player as a chess player in a spatially limited area such as a holiday club, there is no way to find him with a conventional cell phone, even if the person is available in the same club facility.

In a comparable situation, for example, as a customer at a trade fair in a spatially limited area, you are looking for the provider of a specific product that has a specific demand profile.

There are a very large number of comparable situations in which a customer looking for a person or a product with a specific demand profile does not find the right provider, even if this provider is in close proximity.

It is therefore the object of the present invention to provide a cell phone for establishing contact, which makes it possible to find a provider who corresponds to a demand profile.

This object is achieved by a cell phone for contacting the features specified in claim 1.

FIG. 5 shows a preferred embodiment of the mobile radio device or cell phone 1 according to the invention. The mobile radio device 1 for making contact contains a transmitting device 2 for transmitting a transmission signal and a receiving device 3 for receiving a received signal. The transmission device 2 is connected on the output side to an antenna 4 for radiating the transmission signal. The antenna 4 serves both to send the transmission signal and to receive the reception signal. The receiving device 3 is also connected to the antenna 4.

The mobile radio device 1 serves as a transmitting and receiving device and has various memories. At least one demand profile record (NPDS) can be stored in a demand profile record store 5. The demand profile record includes multiple demand characteristic data. An example of a demand profile data record is shown in FIG. 7. The demand profile data record can be defined by the user of the radio device 1 and is entered via an input device (not shown), for example via a cell phone keyboard.

As a further storage device, an offer profile data record memory 6 is provided in the mobile radio device 1 according to the invention, which serves for the intermediate storage of received offer profile data record (APDS). In a preferred embodiment of the mobile radio device 1 according to the invention, at least one user profile data record memory is also provided. In the preferred embodiment shown in FIG. 5, a RAM memory 7 is provided in which personal data of the radio user that the radio user himself inputs via the keyboard are stored. In the user profile Record store 7 stores at least one user profile record (NUPDS) with several user profile feature data. An example of a user profile data record is given in FIG. 12.

In addition to the RAM memory 7, the preferred embodiment of the mobile radio device 1 according to the invention shown in FIG. 5 also has a ROM memory 8 in which a non-programmable second user profile data record (NUPDS) can be stored, which cannot be overwritten by the radio user. Examples of user profile data records which cannot be overwritten and which are stored in the ROM memory 8 are given in FIGS. 9a, 9b. In a preferred embodiment, the user profile data records that cannot be overwritten can be read out with an external reading device.

In the preferred embodiment shown in FIG. 5, a microphone 9 is also provided, which detects a speaker signal from the radio user. The microphone 9 is connected on the output side to an analog / digital converter 10, which converts the analog electrical voice signal into digital voice data. The radio 1 also contains a multiplexer 11, which is connected on the input side to the two user profile data record memories 7, 8, to the demand profile data record memory 5 and to the analog / digital converter 10. Depending on a first control signal (CRTL _S ), the multiplexer 11 switches the speech data, at least one demand profile data record NPPS or the user profile data records NUPDS from the memories 7, 8 to the transmission device 2. The first control signal CRTL _S is generated by a control unit 12 of the mobile radio device 1.

In a first operating mode of the mobile radio device 1, the transmitting device 2 sends the demand profile data record alone (NPDS), which is stored in the demand profile record memory 5.

In a further operating mode, the transmitting device 2 transmits both the demand profile data record NPDS from the demand profile data record memory 5 and a user profile data record NU-PDS, which is temporarily stored in the memory 7. The demand profile data record NPDS describes a demand profile which comprises characteristics of a product or a person. The user profile data record NUPDS, which is optionally additionally sent, describes features of the user of the radio device 1.

In a further operating mode, the transmitting device 2 also sends an SMS message entered by the user together with the demand profile data record (NPDS). Such an SMS message could read, for example: "I am urgently looking for a car with the attached demand profile ...". In a preferred embodiment, the user profile data record additionally includes image data of the user, the image data for example showing the face of the mobile radio user.

The storage devices contained in the mobile radio 1, i.e. in a first embodiment of the mobile radio device 1, the user profile data memories 7, 8, the demand profile data memory 5 and the offer profile data memory 6 are integrated in the radio in terms of circuitry.

In an alternative embodiment, the storage devices 5, 6, 7, 8 can be inserted and exchanged in the mobile radio device 1.

On the receiving side, the mobile radio device 1 contains a de-multiplexer 13 which transmits the data emitted by the receiving device 3 as a function of a second control signal CRTL _E separates. The second control signal CRTL _E is also generated by the control unit 12. In the preferred embodiment shown in FIG. 5, the demultiplexer 13 has two data outputs, the first data output being connected to the offer profile data memory 6 and the second output of the demultiplexer 13 being connected to a digital / analog converter 14. Depending on the second control signal, the demultiplexer 13 separates the received offer profile data from the received speech data. The speech data are converted by the digital / analog converter 14 into an analog electrical speech signal, which in turn is converted into an acoustic reception signal by a loudspeaker 15. The mobile radio device 1 according to the invention, as shown in FIG. 5, is therefore suitable both for the transmission of profile data and as a mobile telephone device.

In a preferred embodiment of the radio device 1 according to the invention, it additionally contains an evaluation unit 16. The evaluation unit 16 is connected on the input side both to the demand profile data record memory 5 and to the offer profile data record memory 6. In a preferred embodiment, the evaluation unit 16 compares the offer profile data records received from the radio device 1, which are temporarily stored in the offer profile data record memory 6, with the self-sent demand profile data record, which is temporarily stored in the demand profile data record memory 5. The evaluation unit 16 checks whether the individual offer profile data records match the sent demand profile data record and selects the matching offer profile data records. The selected offer profile data sets are displayed by the evaluation unit 16 to the user of the mobile radio device 1 by means of an optical display device 17. Examples of the display of offer profile data records can be found in FIG. 8 and in FIG. 11. In a preferred embodiment, the evaluation unit 16 selects the offer profile data records according to the number of offer feature data that match the demand characteristic data of the demand profile data record. Those offer profile data records which have the most matches with the self-sent demand profile data record are first displayed in the display device 17.

In a particularly preferred embodiment of the radio device 1, the transmitting device 2 transmits the profile data records with an adjustable transmission power. The transmission power is preferably increased to extend the transmission range if the number of matching profile data sets selected by the evaluation unit 16 is below an adjustable threshold value. The transmission power is also reduced in order to reduce the transmission range if the number of matching profile data sets selected by the evaluation unit 16 is above an adjustable threshold value.

The radio device 1 according to the invention, as shown in FIG. 5, is integrated in a conventional portable cell phone. Each conventional cell phone according to the prior art, as shown for example in FIG. 4, contains a transmitting device and a receiving device.

FIG. 6 shows the integration of the mobile radio device according to the invention for establishing contact in a conventional cell phone according to the prior art. The transmission device 2 is formed by a channel coding unit, a synchronization unit, a channel multiplexer, a modulator and an RF transmitter. The receiving device 3 is an RF receiver, a Demodulator, a channel demultiplexer, a synchronizing circuit and a channel decoding circuit are formed.

The controller 12 switches the cell phone 1 to normal speech mode in an operating mode. For this purpose, the output of the analog / digital converter 10 is switched through to the transmitting device 2 by means of the multiplexer 11 as a function of the control signal CRTL _S. In this way, the cell phone 1 sends the speech signal, which is spoken into the microphone 9, as a high-frequency speech signal via the antenna 4. In the talk mode, the demultiplexer is also switched by means of the second control signal CRTL _E such that the output of the receiving device 3, ie the output of the channel decoding circuit, is switched to the input of the digital / analog converter 14. The received speech signal is thus emitted via the receiving device 3 through the digital / analog converter 14 to the loudspeaker 15 of the cell phone 1.

In a further operating mode, the controller 12 switches over to the transmission of profile data records. For this purpose, the multiplexer 11 and the demultiplexer 13 are switched depending on the control signals CRTL _S , CRTL _E. In this way, the demand profile data stored in the demand profile data memory 5 reaches the transmission device 2 via the multiplexer 11. The demand profile data is emitted by the antenna 4 as a demand profile signal. The offer profile data records received via the antenna 4 arrive in the offer profile data memory 6 of the cell phone 1 via the receiving device 3 and the multiplexer 13.

The evaluation unit 16 compares the received offer profile data records APDS with the demand profile data record NPDS stored in the memory 5 and checks them for matching features. The evaluation unit 16 preferably sorts the incoming Bid profile data records APDS of the memory 6 according to the number of features that match the features of the demand profile data record NPDS.

The sorted offer profile data records APDS are displayed by the display device 17. In a particularly preferred embodiment, the display device 17 displays, in addition to the received offer profile data records, the cell phone number of those mobile radio devices 1 from which the cell phone 1 received the various offer profile data records after sending the demand profile data record. In addition, the display device 17 optionally additionally shows the number of matching features and the transmission range in accordance with the set transmission power.

In one possible embodiment, the transmission power is automatically readjusted by the cell phone according to the invention in accordance with the number of offer profile data records received.

In an alternative embodiment, the mobile phone user can set the transmission range manually.

In a preferred embodiment, the speech data and the profile data are interleaved with another multiplexer interleaved in a time-division multiplexing process, so that the user does not noticeably exchange demand and offer profile data sets with other users during the telephone conversation with a specific person. In a preferred embodiment, the transmitting device 2 transmits the stored demand profile data record via the antenna 4 at periodic time intervals. In a further embodiment, the mobile radio device 1 according to the invention has, as shown in FIG an interface (not shown) for storing the received offer profile data records in a database.

FIG. 7 shows an application example for the mobile radio device 1 according to the invention for establishing contact. In this application example, the mobile radio device 1 is used to establish business contact. A user is looking for a certain type of car at an automobile fair for classic cars that is supposed to meet certain demand characteristics. In the example shown, the inquiring, searching user is looking for a car with the following features: the car is supposed to be a Mercedes, built until 1978, which has six cylinders and an automatic transmission.

The user sends this demand profile data record using his cell phone 1 within the exhibition hall and, in the example shown in FIG. 7, receives three offer profile data records A-PDS-Sl, A-PDS-2, A-PDS-3. The first offer profile record 1 has two matching features, the second offer profile record 2 has four matching features, and the third offer profile record 3 has three matching features. The evaluation unit 16 compares the demand profile data record N-PDS with the three received offer profile data records A-PDS and sorts the offer profile data records according to the number of matching data record features.

The evaluation device 16 displays the sorted offer profile data records in accordance with the feature match, as shown in FIG. 8a. The degree of feature matching or the number of matching features and the mobile phone number of the associated user are preferably displayed on the display device 17. In this way, the user of the mobile radio device 1 is able to identify that person or to call the user whose offer profile data record APDS shows the highest degree of agreement. In the example shown in FIG. 7, this is the mobile phone user who has sent the offer profile data record 2 back to the demand. In preferred embodiments, further information is displayed, for example the own transmission range corresponding to the transmission power set or the direction from which the received signal was received.

In a preferred embodiment, the mobile phone user who sends back an offer profile data record A-PDS after receiving a demand profile data record N-PDS can suppress his mobile phone number. As can be seen in FIG. 8a, the mobile phone user who sent the offer profile data record A-PDS-3 has suppressed his mobile phone number, so that it is not shown on the display of the inquiring user. In a preferred embodiment, however, the button "Number suppressed" can be activated by the inquiring mobile phone user. If, for example, the mobile phone user moves a cursor on the display device 17 to the "number suppressed" button and presses a dial key, the mobile phone number is dialed and a telephone connection is established and between the two mobile phone users.

FIG. 8b shows an alternative embodiment for a display in which the requesting mobile phone user is shown the direction and distance of those mobile phone users who have sent the offer profile data records back upon request. For example, the mobile phone user who sent the offer profile data record A-PDS-2 with four matching features is in a direction indicated by the associated arrow at a distance of 20 meters. The profile data records are preferably sent repeatedly periodically, the duration and period being selectable or permanently implemented. are mented. In one embodiment, the distance is determined from the amplitude of the received signal, the amplitude of the transmitted signal preferably being normalized. The closer the cell phone is, the less signal attenuation there is. The received signal amplitude is correspondingly higher.

In an alternative embodiment, the distance is determined by measuring the signal transit time of a predetermined measurement signal in accordance with a predetermined protocol.

The amplitude of the received signal can be displayed, for example, as a bar or the like on the display device. The higher the amplitude, the shorter the distance between the two phones.

The correct direction is indicated, for example, by an arrow in the display or by an LED lighting up, the LED lighting up most strongly when the user holds the cell phone in the correct direction or goes in this direction. The direction is determined without determining the absolute position of the two users, but based on the signal direction of the received signal, i.e. based on the relative position of both users. It is therefore not necessary to integrate a GPS receiver in the cell phone according to the invention, which reduces the manufacturing costs. In addition, regardless of the position detection systems (e.g. GPS, Galileo system), the cell phone can always be used in search mode. Another advantage is that the cell phone is lighter and smaller because there is no need to integrate a GPS receiver. However, it is optionally possible to provide such a GPS receiver in the cell phone.

FIG. 7 merely represents an application example. The mobile radio device 1 according to the invention is suitable for various most situations in which business contact is desirable. Other conceivable areas of application are, for example, brokering securities or products on a stock exchange or buying and selling products on a local market.

In a preferred embodiment, the display device 17 displays the number of offers for a specific feature. For example, for the first demand profile characteristic Mercedes 100 offers, for the combination of the demand characteristic Mercedes up to 1978, twenty offers, for the combination of characteristics Mercedes up to 1978 and six cylinders twelve offers, and for the combination Mercedes up to 1978 with six cylinders and automatic transmission, eight offers. In a preferred embodiment, demand can combine the functions signal range and the number of offers for each characteristic level. For example, at a classic car fair, the consumer initially searches with a very large signal range and with relatively few demand profile characteristics, in order to first determine how many offers meet at least a few characteristics. He can then narrow the search further by increasing the number of demand profile features and / or reducing the transmission range of his demand. The mobile radio device 1 according to the invention is therefore outstandingly suitable for the goal-oriented search of specific offers.

In a preferred embodiment, the mobile radio device 1 according to the invention additionally has a user profile data record memory 8 that cannot be overwritten, as shown in FIG. 5. In this memory, which cannot be overwritten by the user, certain security data, as shown in FIG. 9a, or for example medical data, as shown in FIG. 9b, can be stored. Is in the groove zerprofildatenspeicher 8, for example, a user profile data set as stored in Figure 9a, the mobile phone operated by the user can be used for quick identification, for example, to determine the passport number. The cell phone 1 can thus be used for personal identification, for example at borders or for police checks.

In an alternative application, medical unchangeable data of the user, for example the blood group of the user and certain allergies which are relevant to the emergency doctor, are stored in the ROM 8. A user profile data record that cannot be overwritten can preferably be read out by an external reading device. For example, a situation is conceivable in which a paramedic or emergency doctor comes to an accident site at which a mobile phone user with a mobile radio device 1 according to the invention has to be given medical care without this person being still accessible. The medic is then able to read the medically relevant data with the external reading device and can immediately determine the person's blood type, for example. To avoid confusion, the user profile data record can contain image data about the person using it, so that the medic can determine whether this is really the medical data of the person to be cared for.

Another corresponding area of application is in medical practices that want to quickly read out relevant data about the patient.

The mobile radio device 1 according to the invention can also be used excellently for the private sector in addition to the business sector. The mobile radio device 1 according to the invention is particularly suitable when searching for private contacts. FIG. 10 shows an application example in which a male mobile phone user takt is looking for a woman who is not supposed to be older than 35, has black hair and is an academic if possible. In the example shown in FIG. 10, the searching user receives three offer profile records, the first offer profile record A-PDS-1 having three matching features, the second offer profile record A-PDS-2 four matching features and the third offer profile record A-PDS-3 having three matching features having.

Figure 11a shows the corresponding display of the display device 1 of the cell phone. The lady with the most matching characteristics is displayed first on the list, with her mobile number optionally also being displayed. In this application example, the user can optionally also send a user profile data record NU-PDS, which is stored in the user profile data record memory 7. /

As can be seen in FIG. 11 a, the cell phone user who sent the offer profile data record 3 has suppressed his cell phone number and instead sent a selectable switching symbol in the form of a heart. If the inquiring mobile phone user moves a cursor on the display symbol 1 onto the switch symbol and presses a dial key, the mobile phone number of the mobile phone user who sent the offer profile data record A-PDS-3 is automatically dialed and a corresponding telephone connection is established.

FIG. 11b shows an alternative embodiment for the corresponding display, in which the direction and distance of the mobile phone users, the offer profile data records, is displayed instead of the mobile phone number.

FIG. 12 shows an example of such a user profile data record. Optionally you can also send an SMS message as well Image data of the searching user are sent together with the demand profile data record.

FIGS. 13a, 13b show further possible variants of the demand profile data record NPDS as it is stored in the memory 5 and of the offer profile data record APDS as it is buffered in the offer profile data record memory 6.

In the variant shown in FIG. 13a, the user can assign weighting coefficients to the various demand characteristics in order to weight particularly important characteristics. In addition, he can use flags to indicate that certain characteristics must be fulfilled in order for the offer profile data record APDS to be in at all Is being considered. In the example shown in Figure 13a, e.g. the demand characteristic "female" must be fulfilled so that the received profile data record is not completely selected by the evaluation unit 16.

FIG. 13b shows a variant of the offer profile data record in accordance with a preferred embodiment. The offer profile data record additionally receives a fulfillment flag for each offer characteristic, which indicates whether the requested characteristic is fulfilled or not. Accordingly, each offer characteristic consists of two fields, which includes a fulfillment flag and a specification. This considerably facilitates the evaluation by means of the evaluation unit 16. The user who receives a demand profile data set looks at the characteristics and decides characteristic by characteristic whether he can offer or fulfill this characteristic. If he fulfills this characteristic, he enters, for example, a 1 on the keyboard of the cell phone, while if he does not fulfill the characteristic, he enters a 0. For each feature, he can also enter a specification via the keyboard, corresponding to an SMS message. FIG. 14 shows a diagram for explaining the functioning of the mobile radio device 1 according to a first operating mode. In this operating mode, the cell phone 1 is used as a transmitting and receiving device without establishing a radio connection with a base station. In this operating mode, the inquiring mobile phone (N mobile phone) sends a demand profile data record within its transmission range to the mobile phones A-Handy-1, A-Handy-2, A-Handy-3, which are within the transmission range. Offer profile records can be returned from these phones.

As shown in FIG. 15, the cell phone 1 sends the demand profile data set in a second operating mode as a transmission signal in a first frequency band to the nearest base station BTS, which preferably transmits the received demand profile data set in a second frequency band to all cell phones located in the associated cell phone cell. In an alternative embodiment, the connection to cell phones can also be established via the network in further cell phones.

The mobile phone 1 according to the invention can be switched between two operating modes, in the first operating mode (search mode) a direct contact between two mobile phone users who are within the transmission range is possible without the need for an available mobile phone network to make contact. In this operating mode, two mobile phone users can also contact each other who use different mobile radio networks. In the first operating mode (search operating mode) it is possible, for example, for a DI mobile phone user to contact a user who is a D2 customer. In the first operating mode, it is also possible for the user of the requesting mobile phone to to actively find mobile phones by means of directional aiming, as was described, for example, in connection with FIG. 8b. The range can be adjusted automatically or manually or gradually or by the user. In this search mode, the user can set the transmission and reception sensitivity depending on how many contacts are desired. When a predetermined key (PTT - Push to Talk) is pressed, a radio voice connection is established in the search mode, which does not take place via the mobile radio network, but via a direct radio contact, ie half duplex (Walky Talky) or full duplex.

The user can switch between the two operating modes by pressing a button. In the second operating mode (network operating mode), contact is made via a mobile radio network. In the second operating mode, it is possible for the user to download input masks or to have them sent to them in a preferred embodiment.

Figure 16 shows an example of such an input mask. In the example shown in FIG. 16, the input mask consists of a user profile data record mask for cars. The first data field concerns the brand of the desired car, the second data field the year of manufacture and the third data field, for example, the transmission of the car. For the brand, the user can choose between the brands Mercedes, Porsche, Opel ... while the year of construction can choose between 1900 and 2004. He can also choose between a manual transmission and an automatic transmission when looking for a car. The mobile radio operator or provider can provide the customer with such profile data record masks for inputting a search profile or offer profile for downloading, similarly to mobile phone ringtones. In an alternative embodiment, such predefined input masks are already stored in the mobile phone 1 and can be called up using the mobile phone menu. Typical examples of such profile data record masks are profile data records such as flirt partners, sports partners, product searches (for example cars) or service searches.

The input masks are preferably stored hierarchically in a menu system of the mobile phone, for example under a menu item "Search" as "Search - business" and "Search - private". The menu item "Search - business" is in turn divided into menu items "Search - Cars", "Search - Service". In a similar way, the search menu sub-item "Search - private" can be subdivided into the menu sub-items "Search-Sport partner", "Search-Flirt partner" ... Mang thus arrives at the specified search data record masks.

The offer and demand data records can be sent or received simultaneously or with a time delay. For example, a cell phone user can search a used car and a tennis partner at the same time while offering his own used car. The mobile phone 1 according to the invention enables multiple operation in which a telephone conversation, in particular between the searching user and the provider, can be carried out during the exchange and evaluation of profile data records. Due to the search function, which also shows the direction to the person offering, both people can also approach each other spatially during the conversation by approaching each other. The position is preferably determined using the signal amplitude of the returned offer profile data records without absolute position determination using GPS or the like. The set signal range and the distance to the Tending users and the direction from which the signal comes are displayed optically or acoustically in the search mode.

The evaluation profile records received can be evaluated by the evaluation unit in a variety of ways, taking into account the sequence of the incoming profile data records, their weighting by the user, the number of criteria criteria fulfilled, the distance to the connecting user and the direction received from the profile data record can.
