  • Patent number: 8331918
    Abstract: A system and method concerning the field of call redirecting enables a second subscriber to keep incoming calls, which originate, e.g. from a fixed network connection of a first subscriber but are destined for a radio network connection of the second subscriber, in the fixed network so that they are redirected to a fixed network connection of the second subscriber. This method may result in eliminating network crossover costs that would accrue when using different communications networks for setting up calls. For utilizing the call redirecting function, the second subscriber shares in the saved network transition costs by receiving a bonus resulting from the saved network crossover costs. In order to simplify the utilization of the call redirecting function, a device is assigned to the second subscriber that, when activated, automatically initiates a control call for activating the switchover function.

    Abstract: The invention concerns the field of call redirecting and enables a second subscriber (B) to keep incoming calls, which originate, e.g. from a fixed network connection of a first subscriber (A) but are destined for a radio network connection of the second subscriber (B), in the fixed network so that they are redirected to a fixed network connection of the second subscriber (B). This method results in eliminating network crossover costs that would accrue when using different communications networks for setting up calls. For utilizing the call redirecting function, the second subscriber (B) shares in the saved network transition costs by receiving a bonus resulting from the saved network crossover costs.
