DE20012337U1 - Telephone system with automatic switchover from mobile network operation to landline operation - Google Patents

Description

Description:

Telephone system that enables the operator to make calls to both the mobile network and the landline network using one telephone device.

State of the art:

To date, there is no telephone system that has the ability to automatically switch from mobile network operation to landline operation when the telephone customer is within a certain range of the telephone system.

Problem:

The invention specified in claims 1 and 2 is based on the problem of inventing a telephone system that allows a specially equipped mobile phone to make calls to the landline network.

Solution:

This problem is solved in claims 1 and 2.

Its advantages:

- At home you can now also make cheap landline calls using a mobile phone

- It is also possible to connect to an ISDN system without any problems

- The mobile phone can be reached simultaneously via the mobile number and the landline number if the mobile phone is within a 200 meter radius of the registration station

- Better voice quality (communication quality) is achieved in fixed network operations

- Preselection providers who operate landline and mobile networks have the option of programming the registration station so that their call-by-call number is predialed in landline operation.

- The mobile phone automatically registers at the registration station within a 200 m radius. A small house lights up on the display and assures the telephone customer that they can now make calls on the landline. This process happens automatically.

Example:

The invention consists of two parts: the mobile phone (3) and the registration station (13).

The mobile phone (3) contains the switching matrix (1) and the second antenna (2) in the housing (4), which registers in encrypted form as soon as the mobile phone comes within a radius of 200 meters of the registration station (13). The switching matrix (1) then switches from mobile network operation to landline operation and the house (5) in the display lights up, which guarantees that the telephone customer can now make calls via the landline. The telephone customer can now be reached via his landline telephone number and via his mobile phone number, since the mobile phone remains online even in mobile network operation. However, this new invention gives the customer the opportunity, if he is within the radius specified above, to call someone and call the cheaper landline using his mobile phone.

The registration station (13) consists of an antenna (12) in the housing (16) to which the special mobile phone (3) can register in encrypted form (requirement: 200 meter range radius). The preselection chip (11) can predial the preselection number of other Callby Call providers during calls (optional). The coupling (10) recognizes incoming encrypted radio signals from the mobile phone (3) and switches it as a secondary phone to the same landline number as the station phone (15). Other features of the registration station (13) are the F-coded input (7), which connects the registration station (13) to the TAE socket (6) via an F-coded cable (14), the F-coded output (8) which establishes the connection to the station phone (15) via an F-coded cable (14), an N-coded connection (9) is also available as an option. The registration station (13) is supplied with energy via a power cable (18) connected upstream of a voltage converter (17) which has the following features:

Input: 230V/50HZ/56mA/13Va
Output: 8.6 volts/590 mA/5.1 Va

An embodiment of the invention is explained with reference to Figures 1 and 2. They show:

Possibility (on request) of built-in preselection device, as installed in the telephone customer's home.

Claims (2)

1. Joint use of a mobile phone with a landline and a mobile phone network. A station telephone antenna is built into the mobile phone, which, in conjunction with a switching matrix, switches from mobile phone operation to landline operation when the registration station receives a positive signal. If the mobile phone no longer receives a signal from the registration station, i.e. the telephone customer moves out of the 200 meter reception radius (or similar range) of the registration station, the switching matrix switches from landline operation back to mobile phone operation. However, the mobile phone remains ready to receive signals via its mobile phone number even in landline operation. 2. The registration station is designed to be installed between the TAE socket and the stationary landline telephone. The registration station has an F-coded input, an F-coded and an N-coded output. As soon as the associated mobile phone is within a 200 meter reception radius (or similar range) of the registration station, the mobile phone automatically registers via the antenna attached to the housing of the registration station. The mobile phone is then registered as a secondary phone to the stationary phone by means of a coupling. A preselection chip, which can be optionally installed between the coupling and the antenna, automatically predialls the number of the preselection provider during a telephone call.
