Definitions
- the invention relates to a mobile radio telephone for multi-mode operation according to the preamble of claim 1, as is known from DE 4307966 AI and also from DE 19532069 AI, and also has the use of relay stations for such mobile radio telephones .
- a multi-mode telephone of the type mentioned at the outset fulfills the special requirement that the same device can be used in different modes of operation, in particular on the one hand according to the GSM standard (Global System for Mobile Communication) for mobile radio (in Germany Dl-Telekom and D2-private) and on the other hand according to the DECT standard (Digital Enhanced (formerly: European) Cordless Telecommunications) for cordless telephones; Details of these standards are e.g. discussed in WO 96/38991.
- GSM Global System for Mobile Communication
- DECT Digital Enhanced (formerly: European) Cordless Telecommunications
- the change between these operating modes can also take place automatically, for example on the basis of field strength measurements, as described in detail in DE 19532069 AI. It is also possible for the telephones in the local operating mode not only to communicate with one another via the relay station, but also as described in EP 0739149 A2.
- the devices which communicate locally or directly with one another are identified using a special code which excludes unauthorized devices from communication.
- This task is done with a cellular phone
- Claim 7 specifies the manner in which relay stations are used together with such mobile telephones.
- Essential for the mobile radio telephone according to claim 1 and accordingly also for the use of a relay station according to claim 7 is the fact that the identification of the communication partner in the mobile radio network-free mode of operation is not carried out or not only by a special code that only the limited number assigned by participants belonging to the individual (DECT) system. Rather, the identification is carried out by means of the mobile phone number which is assigned to the mobile radio telephone for participation in the mobile radio network by inserting a SIM card therein. So it is possible that any subscriber, represented by his SIM card with the assigned mobile phone number, can also be reached "cordlessly" under this number and is thereby clearly identifiable. What is needed for this is the multi-mode mobile phone in which the SIM card is inserted, which is then not only used for
- Identification of the participant when communicating in the first operating mode i.e. in the GSM network, but also for identification in the local connection (DECT).
- the reference to the GSM standard and to the DECT standard in the first and second operating modes is to be understood as an example of such operating modes in order to clarify the invention. It is only important that the first operating mode is a (in general public) cellular network and in the second mode of operation is a (usually privately used) type of connection which is locally limited to the reception area of (a few) relay stations and in which usually at least one of the respective
- the conversation partner belongs to a group of participants who is authorized by the operator of the relay station to use it, or where the operator at least tolerates this use.
- a direct connection between the mobile radio devices without a relay station is also to be included.
- the multi-mode device If the multi-mode device is located in the area of a relay station in which it is authorized, it can (as in the prior art according to DE 4307966 AI) in the (local) second operating mode with other authorized devices ( Communicate free of charge via this relay station and from there also (often cheaper) establish connections to the fixed network, provided the relay station is connected to the fixed network. However, it can also communicate with any other unauthorized other mobile phones in this operating mode, provided that they are only equipped according to claim 1 and are also located in the area of the relay station.
- outgoing calls to the fixed network may, of course, only be made by authorized subscribers so that it can be determined who bears the cost of the call; this authorization can be done in such a way that in the relay station the mobile phone number of the SIM card to be authorized entered or that the data stored on this SIM card are read with a reader. Without a special reader for the SIM card, the authorization can also be carried out by establishing a DECT connection from the relay station to the as yet unauthorized mobile phone and reading the SIM card data and storing it in the relay station. Data can also be exchanged to protect against misuse; For example, the authorized subscriber can be assigned a special code number, similar to comparable systems.
- a subscriber who is known to be in the reception area of a specific relay station can be reached by calling this station in the fixed network and by making a local (DECT) call there, in particular even without the called subscriber (or his SIM card) is authorized.
- this relay station must be selected, and the call to the cellular phone is made in such a way that the relay station receives the cell phone number of the subscriber to be dialed as a DTMF code from the calling subscriber and then issues a corresponding DECT call.
- This communication via the fixed network is particularly advantageous in places where there is no possibility of GSM reception.
- Multi-mode mobile phones of the type claimed can be used local (DETC) relay stations to fill gaps in the public GSM network, e.g. in buildings, by private initiative.
- DETC local
- a GSM subscriber is also on a remote one Place or in a building constructed in a shielding construction, where there is no GSM reception, can be reached, provided the caller knows that he is there, and without the called party having to use another telephone, without losing his freedom of movement and without one Callers must inquire about a special extension number for the called party or have to be transferred manually. The caller only needs to know the number of the relay station in the area of which the called party is located.
- the multi-mode mobile telephones In addition to communication via relay stations, it is also possible to equip the multi-mode mobile telephones in such a way that they communicate with one another directly and without the intermediary of a relay station. In this mode of operation, too, the communication partner is identified on the basis of its mobile phone number.
- the simplest case is the direct connection between two multi-mode mobile radiotelephones in the second operating mode, ie without stressing the cellular network but also without using a relay station.
- a connection between two ships that are not too far apart is made possible, which are no longer in the area of a GSM transmitter, without any additional devices being necessary.
- the direct connection will nevertheless be preferred because it is free of charge. Therefore, the first attempt is to establish a connection in this operating mode.
- the second operating mode can be switched off.
- the devices When establishing a connection in the second operating mode, the devices identify one another on the basis of their mobile telephone numbers used during the connection establishment, which have been assigned to them in the first operating mode by inserting the corresponding SIM card for communication in the mobile radio network.
- the caller does not need to know whether the called party is close enough to establish a direct connection; he only dials the mobile phone number of the desired call partner. If the direct connection is not established, a connection is automatically established via the mobile network.
- the operating mode of the device is displayed to the caller so that he can monitor his costs.
- the applications are more diverse when a relay station is used in the second operating mode, as this increases the range of the toll-free connection (DECT).
- a reporter team can, for example, maintain a cost-effective connection to one another at a large sporting event, or can also reach non-team members, provided that they also have a device equipped according to claim 1. If an unauthorized use of the relay station is to be excluded, it is necessary that at least one of the two interlocutors is legitimate. Another Subscriber - who does not have a mobile radio telephone according to claim 1 or is not in the area of the relay station - is reached as usual by a GSM mobile radio connection. In any case, it is not necessary to find out under which number the person can now be reached, because this is always the mobile phone number, and also not whether the called party is in the area of the team's relay station and whether he claimed his SIM card with a device
- relay stations can be used, between which a fixed connection of any type is provided, e.g. in the case of portable systems. via satellite.
- the caller must of course be aware of incoming calls that the called subscriber is equipped with a mobile radio device of the type claimed and in the area of which relay station he is.
- the caller can dial the relay station for the charges for the fixed network, for example for the local call charges, and when the connection is established, the caller's mobile phone number is transmitted using the DTMF code. This gives the relay station the opportunity to try to establish a DECT connection to the desired subscriber. A legitimation of the called party is not absolutely necessary.
- a possible application of this operating mode is in retail, e.g. conceivable in a department store. If such a relay station is used within the business premises, every customer who carries a mobile phone of the type claimed with him can have himself made a call within the business via the fixed network and thus possibly for local charges, e.g. Discuss with the partner in peace whether or in what quality a certain product should be bought. Outgoing calls to the fixed network need not be permitted when using a relay station.
- the relay station is connected to the fixed network and can be designed, for example, as an additional device for an ordinary telephone.
- An incoming call can, as usual, either be routed through to all subscribers authorized at the base station and a connection is set up to the device that answers first, or a specific extension is addressed, i.e. either an ordinary DECT handset or a device that The extension causes the relay station to establish a connection to the mobile radio telephone, the mobile phone number of which is assigned to this extension.
- a special extension for other participants can be provided.
- the call is accepted by the relay station, and the caller uses a DTMF signal to transmit the cell phone number of the guest and can reach him at the fixed network charges, even if no GSM reception is possible.
- a cellular connection or a connection to the fixed network can be established, the latter of course only for a subscriber who is authorized to do so.
- the relay station determines whether this is the case by means of the mobile telephone number, which the multi-mode mobile radio telephone takes from the inserted SIM card and transmits it to the relay station, it being possible for an additional code to be transmitted in order to prevent misuse avoid.
- the functional sequence is as follows: A DECT call goes from the mobile phone, which is received by the relay station and contains the dialed number. If the information is also transmitted that there is insufficient GSM field strength, a connection is always established via the fixed network.
- the further procedure is as follows:
- the current telephone tariffs are available in the relay station depending on the date (weekday, holiday), time and location (distance range, network, country, if applicable), and for the selected call partner the applicable minute price is determined according to its number, once for a call via the mobile network and once over the fixed network. If this results in a cheaper tariff for a connection via the fixed network, which will be the case, for example, with local calls, the relay station establishes a connection via the fixed network.
- the multi-mode mobile radio telephone switches to the first operating mode and establishes a connection via the mobile radio network, which will be the case, for example, with the inexpensive calls between mobile radio telephones in the common “home network”.
- connections in the area of the relay station are also possible, whereby only one of the participants needs to be legitimized, so that such calls e.g. can also be led with guests etc.
- Another embodiment is suitable for a company with several branches, possibly even in different countries. There are several relay stations connected to each other via dedicated lines.
- a DECT call is first attempted. If this is successful, a DECT connection is established, whereby the devices differ in the area
- Relay stations can be. If the called mobile radio telephone is not in the seride and reception area of a relay station, if the dedicated line is overloaded, or if the called subscriber is not equipped with a device according to claim 1, ie if he does not insert his SIM card into such a device has - in short, if the DECT call was unsuccessful, there is first a manual or automatic cost comparison between a mobile connection and a connection via the fixed network, it being possible to take into account that dialing into the fixed network at different relay stations can result in different charges. For example, if the calling subscriber is in Munich and there is a connected relay station in Hamburg, each set of devices in Hamburg can be reached for local call charges.
- each mobile radio telephone can be reached under the same number under all circumstances and, nevertheless, the function of a wired private branch exchange with its cost advantages can be achieved completely.
- Other features of a conventional private branch exchange can also be realized in an obvious way with the relay stations, e.g. transferring a call to another subscriber on a call forwarding.
- a final application and embodiment concerns the equipment of a hotel. So far, a hotel guest who wants to make a phone call can do so on the one hand with his own mobile phone; on the other hand, it is possible to make a call from a hotel telephone, for example from the device in his room.
- the first option is subject to high call charges, especially when you are abroad. In addition, there is not a sufficient GSM signal in all hotel buildings.
- the second variant is cumbersome because the guest is local. The same applies to incoming calls: If the number of the hotel is dialed, it may be difficult to find the guest (room, conference room, bar, etc.) or to determine whether he is in the area of the hotel. In contrast, with the claimed multi-mode mobile phone, it is possible to use the same device that the guest carries with him or that he may be borrowed from the hotel (without a SIM card),
- An arriving guest who carries his own mobile radio telephone which is equipped according to claim 1, calls the receptionist his mobile number, or this is read by means of a reader from his SIM card, and via an input unit (keyboard ) of the relay station further data of the guest (name, address, room number) are entered. This authorizes this mobile phone to participate in communication with the hotel's relay station and in particular for outgoing calls to the fixed network.
- this process can be used to exchange additional data, such as code numbers, to secure the system against misuse.
- Such a call can be identified as directed to a specific hotel guest in that after the connection has been established in the fixed network, the mobile telephone number of the called party is transmitted using DTMF codes.
- the relay station can then establish a DECT connection to it
- Switch device through. It is up to the hotel operator (i.e. the operator of the relay station) to forward calls only to registered hotel guests (and may charge them a fee), or all calls, e.g. also those that are aimed at visitors of the guest, i.e. ultimately for any person staying in the hotel (in the area of the relay station) and carrying a mobile phone of the type claimed with them.
- the hotel operator i.e. the operator of the relay station
- all calls e.g. also those that are aimed at visitors of the guest, i.e. ultimately for any person staying in the hotel (in the area of the relay station) and carrying a mobile phone of the type claimed with them.
- hotel guests can also communicate with each other free of charge outside the range of the relay station if they are not too far apart, possibly with the help of the loan devices.
- the computer of the relay station bills the calls made by the guest according to the tariffs of the hotel and the authorization of his SIM card is deleted.
- the hotel has the particular advantage that, with increased flexibility, no hard-wired telephone system is required, regardless of the prevalence of multi-mode telephones, and that a special service is offered in areas without GSM coverage; this is particularly interesting for new hotel buildings.
- Upstream organization need more via a GSM connection: As long as the assignment exists, a DECT call setup, in which the partner is identified using the mobile phone number, is easily possible. The registration of the DECT part of the multi-mode mobile radio telephone can then continue permanently, even if the SIM card is replaced, provided that only the new mobile phone number assigned to the multi-mode device is immediately transmitted to the relay station. In any case, the
- Handheld devices that can be logged in at a relay station at the same time are limited and the maximum number has been reached, the multi-mode mobile radio telephone that has not been used for a long time can be booked out as a handheld device when a new registration is requested; other handheld devices are not affected and are not fully booked.
- the current GSM connection can be continued immediately as a DECT connection.
- the automatic login can also take place if a call is not to be made immediately by calling a special extension number reserved for this purpose from the multi-mode mobile radio telephone (via GSM) at the relay station.
