Abstract

Method for switching telephone connections with the following steps:
Dialing a switching node by a first subscriber using the cheapest tariff offered by a first mobile telephone,
Dialing of a second mobile telephone of a second subscriber by the switching node,
• Display of the message "Disconnect" on the display of the second mobile phone,
Interruption of the second connection by the second mobile telephone of the second subscriber, wherein the first connection between the first subscriber and the switching node is held by the first mobile telephone,
Dialing of the switching node by the second mobile telephone of the second subscriber using the cheapest offered tariff,
• Automatic connection of both parties by the switching node.

Description

State of technology

The Invention is based on a method for switching telephone connections, especially for Mobile phones, according to the preamble of the main claim.

at the use of mobile phones, the tariffs are confusing and expensive. There are many different tariff models. On the one hand there are tariffs with a relatively high basic charge, but comparatively low connection fees and secondly royalty-free Tariffs with correspondingly high connection fees. In addition, special rates offered in which individual specified desire numbers or preferred area codes particularly favorable Connection tariffs valid are. A disadvantage of these tariff models is that the mobile phone user not for every connection can use the most favorable tariff.

When favorable Alternative offer so-called Callback or Callthrough Provider at. These are telecommunication service providers, the network resources in large Scope of purchase or rent and special phone numbers and digit strings, called PINs, these resources to the mobile phone user at a favorable price Tariff available put.

Around using a callback provider to call, selects the Phone users a phone number assigned to him alone, leaves it there ring once and hang up. This process is referred to as the so-called "lure call." Seconds later, usually after 3-12 Seconds, the phone user is automatically called back and gets a dial tone when he accepts the call. Now the Number of the desired Call participant, the so-called "destination number" are entered, transmitted as a DTMF tone sequence becomes. As a result, the connection is established.

at a callthrough provider first gets the number of the provider selected and enter a so-called PIN number followed by the actual "destination number." The PIN number serves to identify the service user. This identification can also be otherwise, for example by CLIP (Calling Linde Identification Presentation).

in the Case of call-through calls arise frequently such long digit sequences, especially with mobile phones in the Usually not in one existing integrated phone book can be saved, but cumbersome with every telephone call must be entered by hand.

A device is known for arranging telephone conversations ( DE 101 43 543 A1 ). In this device, a first mobile telephone is equipped with an incoming call channel and an outgoing call channel when switching to a second mobile telephone or a landline telephone. A telephone number that is callable at a comparatively low rate is associated with the device. The device can be called on one of the channels via the said telephone number from the first mobile telephone, receives the number of the second mobile telephone or landline telephone after setting up the connection and dials this number automatically via the other channel.

at of this device as security measures Ident numbers are entered, which are checked by means of the device.

Also known is a method and device for the cost-effective switching of connections in mobile radio networks ( DE 100 29 224 A1 ). In this case, a calling end subscriber establishes a call to a service provider via a mobile network operator under a desired number. This call is fed to a switching computer of the service provider. The switch computer establishes a second connection between the service provider and a called end user. This second connection takes place via a second network operator, in particular a fixed network of a fixed network operator. The selection takes place via a call-by-call provider or similar. The phone number of the second service provider is set up as a special phone number.

The Invention and its advantages

The inventive method with the features of the main claim, in contrast, the Advantage on that for the mobile phone user different ways of mediation process to be provided. The mobile phone user can via a Desired number, for example, under the selected tariff-favorable Area code, either via a telephone software integrated in his PC, via a programmable telephone modem or over a central operator telephone computer the desired Select participant. The Selection is via the phone number stored in the phonebook of the mobile phone via the speed dial key or over entering the phone number using the keyboard. To the connection with the intermediary, the discounted tariffs of the Internet, one Telephone flatrate or similar effective.

According to the invention, the mediator, who acts as a switching node between the dialing mobile phone user and the called second subscriber, establishes a connection to the second one Participants on. In the display, so for example the display of the second participant, the number of the caller appears and a note: "Cancel connection." The second subscriber can now call the switching node, which terminates the connection via abbreviated dialing or key input on the cheapest rate after canceling the connection to the first mobile phone and merge the two, ensuring that both phone users use the cheapest fare for the call.

Further Advantages and advantageous embodiments of the invention are the following description, the drawing and the claims.

Drawing:

One embodiment The invention is illustrated in the drawing and in the following described in more detail. It shows:

1 : a flowchart of the method.

description of the embodiment

One Mobile phone user calls his interlocutor via speed dial at. The conversation will automatically over directed your own PC. The connection to your own PC, the one especially for that trained software, at the best available rate, for example, by the selected area code. The PC recognizes the subscriber number and establishes a connection. The caller's mobile phone's display shows the number or, if the number is stored in the speed dial directory of the called party is, the name of the caller and in addition the note: "Cancel connection".

Of the Called can now decide whether to connect to the from PC held conversation wishes or not. about his own speed dial or the key input of his mobile phone or the callback function he can, in turn, the cheapest Exploiting the tariff, call back the switching node, in this case the PC, automatically the recalled Number recognizes and the newly arriving dialing of the originally called Restores with the held call of the original caller.

All in the description, the following claims and features illustrated in the drawings are both individually and in any combination with each other essential to the invention.
