Description

[0037] In the now following, the invention will be described in detail with reference to drawings. It shows:

[0038] FIG. 1 shows a block diagram of the system (1) between a first participant (2) and any second subscriber (3, 4);

[0039] FIG. 2 is a block diagram of a detail of the system (1) in the range of at least one home telephone or, respectively, terminal device (2);

[0040] FIG. 3 shows a flow chart of the method according to the invention with a configured router (5) and at least one pre-installed mobile phone (6);

[0041] FIG. 4 is a flowchart of a second application case of the method according to the invention with a router configured (5) and at least one pre-installed mobile phone (6);

[0042] FIG. 5 shows another flow chart of the method according to the invention with at least one pre-installed mobile phone (6);

[0043] FIG. 6 shows a block diagram of a mobile radio device (6) in which the microphone (12) and the handset or loudspeaker (13) are connected to a switching unit (14).

[0044] The FIG. 1 shows a block diagram of the system 1 with a local subscriber (2) and at least one freely selectable telephone subscriber (3, 4), wherein the freely selectable telephone subscriber can be either a mobile (3) or a fixed network subscriber (4). The system 1 is characterized moreover acted upon by the interaction of a configured router (5) and one characterized with a software (7) impacting the mobile radio device (6). The mobile station (6) can be both a smartphone and tablet, or similar device on which the software (7) is installed. The mobile radio device (6) further includes a VoIP platform (8), which in principle allows a VoIP gateway in a mobile network (9), so that between the mobile station (6) and any telephone subscriber (3,4) call data can be transferred into an IP network. The mobile station (6) is in the range of the router (5) positioned so that it ensures data exchange (14) between these two devices is (for example via wireless, cable connection, USB, etc.). The telephone subscriber (2) is connected to the router (5) via a data link (for example via wireless, WLAN, cable connection, USB, etc.) (10).

[0045] FIG. 2 shows a schematic block diagram in the immediate area of the router (5) which is connected through the data connection (10) to the telephone subscriber (2), or, respectively, is connected to the terminal of the subscriber. The router (5) and the mobile station (6) exchange data wireless through WLAN or a wired data connection (14). The call data originating from the subscriber (2) are transmitted by radio to the mobile network (9) and directed from there to the various telephone subscribers (3, 4). Since it is generally not possible with mobile terminals to take a direct access to the incoming audio data, the headset output of the mobile radio device (6) is connected with an additional electronic switching unit (11) which shortens the microphone (12) to the output of the handset (13). This function is described in more detail below.

[0046] FIG. 3 shows a schematic data-flow diagram of the method according to the invention, wherein the router (5) is already configured according to the requirements of the invention. This procedure describes in abbreviated manner the steps necessary on a mobile phone (6), tablet etc. which furnishes the VoIP server function and the configuration of the terminals to be telephoned to.

[0047] For example in a first step, a software is installed on the phone (6), or a tablet etc. (In the form of an app). The software on the mobile radio device on which the software was installed, in addition to the previous features, a server for Internet telephony (VoIP, Voice over IP) and thus serves as a VoIP gateway in the VoIP platform (8), via which in combination with a further terminal (VoIP client, for example, router) call data over the mobile network (9) can be handled.

[0048] In a second step to configure additional terminals occurs (router with connected telephones, VoIP phone, etc.) so that they log on the device from the first process step. This case is identical to that of the approach here, as if one were at this terminal install a traditional VoIP provider, which also operates the SIP server, but with the difference that the vendor in this case is no telecommunication company is that its SIP Server operates on the Internet, but the provider is in this case the device from the first step on which the SIP server is running.

[0049] The manual configuration of the second step can be optional automated as during the installation of the software from the first process step.

[0050] By installing the software (7) on the mobile radio station (6), the mobile radio station (6) becomes a private provider of telephony services. Due to the integration of the mobile radio device (6) with the software (7) as telephony provider in the domestic telecommunications landscape, the existing home phones (2), while also benefiting from the contractual terms of the mobile phone contract, without changing the terminal or the mobile radio station (6) or, respectively, the need to use the mobile radio station as a terminal.

[0051] FIG. 4 schematically shows the data flow diagram of a further use case of the inventive method, wherein the software (7) has been installed on the mobile radio station (6) and the terminal (2) which is to be used is appropriately configured. This use case corresponds to an outgoing telephone call, in which the data is generated by the subscriber (2) and are to be fed to any desired subscriber (3,4) .

[0052] In a first step, a desired telephone number is dialed at the terminal (2), or, respectively, connected to a VoIP router (5) selected any phone number and the request is forwarded, through the router to the mobile radio phone, tablet, etc. on which the SIP server is installed.

[0053] In a second procedure step, the mobile radio telephone (6) on which the SIP server (7) is installed, receives the request and establishes a connection to the dialed number over the air (9). Then, the terminal from which the request was received, signaled the call setup, then as soon as the called subscriber (3, 4) decreases, and the connection is made to the called party, the successful establishment of the telephone connection to the terminal (2) is signaled and transmits the voice data. Now Sets on one of the participants, this action is signaled accordingly in both directions and the phone connection, or mobile connection is terminated.

[0054] The FIG. 5 shows a third use case of incoming call data, wherein the software (7) is already installed and the terminals (2, 5) of the system 1 are configured and connected accordingly. Here go the mobile radio station (6) call data to the mobile radio phone number (for example 0177 1234567).

[0055] In a second method step, the software (7) recognizes on the mobile radio station (6) the incoming call and the incoming call signals to the router (5). In a further step the router (5) receives the request and signals the incoming call to the connected telephones (2). As soon as a call request enters the mobile radio station (6) for receiving a call request is accepted by a telephone (2) connected to the router, the voice connection is produced. If one of the participants interrupts the connection, that is signaled accordingly in both directions and the phone connection (or Cellular connection) terminated.

[0056] FIG. 6 schematically shows a block diagram of a mobile radio device (6), wherein the microphone (12) and the receiver (13) are interconnected by means of a switching unit (14). In (mobile radio) telephony equipment generally there is simultaneous access to incoming call data (output on the speaker) and outgoing call data (recorded by the microphone) (software and/or hardware technology) blocked. The reproduced through the handset data can usually be lossy only on the speakerphone function of the same device with the microphone and recorded with noise. The switching unit (14) to bypass the function that restriction by short circuit of the microphone and handset. Thus, incoming call data, which are usually represented by the handset can be recorded with virtually no loss over the microphone input of the device. The switching unit (14) used to connect the reproducing listener and recording microphone headset connection or headphones (13) and microphone port (12) of the device.

[0057] With the present invention, in particular with the software (7) is a mobile radio device in general converted to a mobile VoIP server, which is everywhere available where a cellular connection exists. It is not necessary to be used at home with a router. The software (7) can also with any VoIP phones and terminals, which via a data interface (for example WLAN, LAN, USB) are connected to the wireless device, are used to make calls via the VoIP platform on the mobile radio device and receive, without the mobile radio station (6) is used as a terminal. With the provided software (7) of the mobile phone contract and any other persons can over an IP data network, for example on the Internet, made consumers. So could for example. International calls are handled by a device connected to the Internet mobile device that is stationary in the selected countries, from Germany.

[0058] The call is therefore handled according to the conditions of the destination country.
