mobile phone

Description:

Mobile phones are battery-operated, operating in the MHz or GHz range cellular phones in the size of a conventional telephone handset. They are connected either as a "mobile" with a terrestrial relay station or a satellite or as a "cordless telephone" with a range of typically several hundred meters with a base station connected to a telephone network. From DE 91 09 141 U1 a mobile phone is already known, which is designed as a mobile part of a car radio. For this purpose, it contains in addition to the usual control buttons on a telephone still some buttons for operating the car radio, an alphanumeric display field for frequency or transmitter displays and a connector for connecting to the built-in part of the car radio. If the mobile phone is connected to the permanently installed part of the car radio by means of the plug connector, then this can be operated. To make a call, the mobile phone is disconnected from the permanently installed part of the car radio. As long as the mobile phone is removed, you can make a call but not operate the car radio.

the mobile phone, when you turn off the car, then the car radio is at the same time secured against theft, because without the control panel no one can do anything with it.

The present, specified in claim 1 invention broadens the scope of Mobiitelefonen contrast considerably by proposing to provide an infrared transmitter in Mobiitelefon, which is controllable by the already provided for mobile telephones operating buttons and / or additional control buttons. For this purpose, the mobile telephone expediently contains a control circuit, which converts the actuation of the operating keys into an information to be transmitted by the infrared transmitter. For control buttons, which are intended only for the operation of the infrared transmitter, this can be done directly on control buttons, which are also intended for the operation of the phone, only after switching the mode of Mobiitelefons from telephone operation to the infrared transmission mode.

The infrared transmitter and its operation can be selected as is the case with conventional remote control devices, wherein as control circuit for the infrared transmitter preferably a microprocessor is provided, which also controls the telephone functions.

In this way, the mobile phone can be used as a remote control for all possible devices and facilities that are still served by individual infrared remote control units.

Today's Mobiefiefone are often no larger than conventional remote control units. Since the size is essentially determined by the keypad, the alphanumeric display panel and the battery, the mobile phone is not necessarily larger in its external dimensions in that it additionally assumes the task of remote control according to the invention. Since today's mobile phones already served with the help of a menu navigation

In this way, it is possible to extend the menus by those for operating the remote control, and this makes it possible to assign special functions to the telephone operation buttons by selecting a "remote control" menu in the context of the remote control In order to realize the remote control, no or few additional control buttons are needed.

Today's mobile phones are controlled by a microprocessor whose computing, control and storage capacity is not underutilized by the phone functions, but can easily be used for the control of Fembedienungsfunktionen, which allows comfortable remote controls with many input presets. Moreover, it is not only possible to use the mobile phone for remote control of a single device, but for remote control of all possible devices that are suitable for remote control and / or today already have the option of an infrared remote control. The device, which should be remotely controlled in the specific case, can be selected and called up with the aid of a simple menu navigation,

To operate a mobile phone, an unlocked code card is required. If the code card is missing or is not unlocked, you can not telephone. To be able to use in this case, the infrared transmitter and - if available - the infrared receiver, the code of the code card evaluating circuit of the cell is preferably designed so that it unlocks only the phone function or locks, but not the operational readiness of the infrared transmitter and receiver , This has the additional advantage that you can give the phone for the purpose of remote control to another person and prevent by removing the code card that the person uses the phone undesirable to make phone calls.

Due to the many opportunities offered by a mobile phone developed according to the invention, it becomes a personal key component of his

Owner, because it provides such in almost all areas of life access to a variety of devices, facilities, and features that can be handled in the current state of the art only with individual infrared remote control units, which also do not offer at the same time the ability to make calls.

Of the many possible applications, the following are particularly emphasized:

The Mobiefiefon can for remote control of television receivers, of television recording and playback devices (VCRs and players for optical discs), of audio broadcasting equipment, of sound recording and playback devices (magnetic tape, CD players, hi-fi systems), which are already largely equipped with facilities for infrared remote control , be used.

Electronic locking devices, which are operated with an infrared remote control, are increasingly used in vehicles and buildings, such as remote controls for garage doors. For this purpose, a mobile phone equipped according to the invention is also excellent. It could also be used as a passport in electronic access control systems in service buildings or on machines by the mobile phone is a personal access code is stored, which can be sent at the push of a button and received by an infrared receiver of the access control system and evaluated.

For an infrared-operated Haustürschiießanlage an inventively equipped mobile phone can be used as a key or for remote control of computers.

Finally, in a motor vehicle, a mobile phone equipped according to the invention can be used not only for unlocking the door by remote control, but also

also as an electronic ignition key, as an anti-theft device for the vehicle (starting is only possible after entering an individual code), as a control unit for the car radio and also as an anti-theft device for the car radio. It can be used as a control panel for the car radio without having to be connected to this via a plug, as provided in DE-91 09 141 U1. It can therefore also serve to operate the car radio from the rear seats ago, and also the passenger can use his help the car radio more convenient, because he controls the buttons better and the Anzeigeefeid better in view than a permanently installed control panel. The car radio can be protected against theft by being able to operate only with an individual identifier which is programmed into the mobile telephone. The wireless coupling between the mobile phone and the car radio, it is also possible to use the outdoor antenna or glass antenna of the vehicle, which is provided for the car radio, for the transmission and reception operation of the mobile phone. The mobile phone could even be used for voice control of the car radio or a built-in hi-fi system. An infrared interface could send faxes to and from a notebook computer.

Voice-e-mails could be sent directly from the microphone via the mobile phone via a suitable coding decoding device and vice versa from a mailbox to the mobile phone

Messages of all kinds could be transferred to the car on individual call via the mobile phone, which can be played aloud through the infrared connection via the built-in car radio.

Preferably, the mobile phone according to the invention has not only an infrared transmitter but also an infrared receiver so that it can not only transmit messages via the infrared link but also receive messages to enable interactive communication with other devices. That makes eg

the use of the mobile phone as a cordless phone possible if there is a base station of the phone in the same room, which is also equipped with an infrared sensor and receiver.

The accompanying drawing shows an oblique view of an inventive mobile phone whose housing 1 on its small front side a conventional infrared transmitter 2, on its Großfiäche an alphanumeric display panel 3, a control panel 4, a speaker 5 ais earpiece, a microphone 6 and an antenna 7 for the Has telephone traffic. Both the telephone functions and the Fembedienfunktionen be executed and displayed on the display panel 3 via the control panel 4.
