Support device for the mobile unit of a cordless or mobile telephone.

Apparatus for depositing a handset of a cordless or mobile phone

The invention relates to an apparatus for depositing a handset of a cordless or mobile phone, at least one additional device is included for coupling to the handset in the handset an option processor and the storage device, wherein the coupling between the handset and accessory as transmission means of data and / or language is formed in both directions.

Such a device is known from EP 313 776. This storage device for the handset of a cordless phone is equipped such that the dialpad at put-handset remain accessible. Furthermore done by this storage device recharging the batteries of the handset. About additional contacts or inductive coupling device handsfree with the handset is also connected.

The invention is based, to provide for the user of Cord phones usual attachments even when cellular phones available on the object.

This is inventively achieved in that an additional device includes a microcomputer, which is connected via a data bus to the processor choice of handset.

Since storage devices are powered by the mains and subject of the housing size to any restrictions, now, various additional devices can be connected that were not possible with mobile phones because of the limited housing size for the handset. The portable devices remain manageable and clearly, at stationary use must not sacrificing comfort. The demand for storage devices is given for all cordless phones, with mobile phones, especially for small, handheld devices with low transmission / reception performance.

For improved operability, it is advantageous that an additional device contains a microcomputer, which is connected via a data bus to the selector processor of the handset. If this accessory is a Zielrufvorrichtung, one, the keys of Zielrufvorrichtung can appropriate number of participants are selected by a single button at the put-away handset. When connecting the cordless or mobile phone to a PBX or a digitized public switching network, it is advantageous that this additional device contains Anwählvorrichtungen for Phone Features. Thus, the use of features such as for consultation, call transfer, three-way conference, automatic call repeat and call forwarding is possible.

Making calls with cordless or mobile phones will be facilitated by an additional device is a dial pad. Dial a phone number can be common with larger keys than handsets easier. To at all times or at times to be undisturbed, it is advantageous that an additional device is an answering machine. To support the acoustic ringing signal an additional device is an optical Rufsignalvorrichtung. Especially for larger units, it is advantageous that an additional device is a call power amplifier. The frequent replacement of the battery of the handset is characterized spared that one of several additional devices, a charging station for the battery of the handset and / or handsfree is. Thus must the phone no longer be interrupted a manual activity.

The transfer of the necessary information in the coupling of the handset with one or more additional devices can be carried out in various ways. There is no radio channel capacity required when the transmossion is an infrared transmitter / receiver device. A handset must not lie directly on the storage device when the transmitting device is a radio transmitter / receiver device. Since the information exchange takes place via a very small distance, the transmission power can be kept low. A little error-prone transmission is achieved by the action of transmission is a UHF transmitter / receiver device. In the direct laying on of the mobile part on the stacking device, it is possible that the transmossion is an inductive transmission device. An inexpensive and trouble solution is achieved in that the transmission device is a mechanical contactor.

The invention is further illustrated by an embodiment and a drawing. The figure shows the embodiment schematically.

In the figure, a mobile part MT of a cordless phone is shown. In the mobile part MT a mobile coupling device MKE is installed as part of a transmission device. The mobile switching equipment MKE contains except charging contacts for a built-in battery also a multi-pole socket for data and voice transmission. The counterpart of the mobile coupling device MKE is mounted as a stationary coupling device SKE at the lower end of a charging cradle LS a storage device AV. The stationary coupling device SKE contains apart from the two charging contacts a multi-pin connector, used to connect the mobile handset MT is made to additional devices ZE the deployment device AV. The connector may optionally be replaced by an infrared transmission / reception device, a UHF-transmitter / Emfpangsvorrichtung or an inductive transmission device.

In addition to the charger LS three additional facilities ZE exist. Their connection to the handset MT is established via a four-way low-frequency range. It consists of a microphone and a Hörkapselleitung, a line for the hook switch and an interface to dial processor of the handset MT. In the case of a wireless connection, the route is established through appropriate modulation method. As additional devices ZE, an answering machine, a Zielrufvorrichtung and a speakerphone exist. A microcomputer of Zielrufvorrichtung coupled to the processor choice of mobile handset MT.

Thus it is possible with put-handset MT to press a key goal as a comfort telephone to the deployment device AV. From Zielrufvorrichtung from the connection with the choice processor of the handset MT is set up and carried out the automatic choice. After notifying the extension is spoken on the speakerphone.
