Method for mobile radio communication and communication device

摘要

A method for mobile radio communication between a communication partner device and a mobile communication device includes conducting a communication, at least temporarily, via at least two different mobile radio connections in two different mobile radio networks; evaluating the reception quality of receive signals of each mobile radio connection in the mobile communication device; selecting the mobile radio connection with the best reception quality for the mobile radio communication, at least in a receiving direction; deriving different audio signals from the receive signals of the different mobile radio connections; and feeding the derived different audio signals to a delay circuit, which aligns transit time differences and/or the amplitude differences of the derived different audio signals with respect to one another.

1. A method for mobile radio communication between a communication partner device and a mobile communication device, wherein one of the communication devices is a calling communication device and the other of the communication devices is a receiving communication device and wherein at least the mobile communication device has two communication facilities for setting up different mobile radio connections, the method comprising:
conducting a communication, at least temporarily, via at least two different mobile radio connections in two different mobile radio networks; evaluating the reception quality of receive signals of each mobile radio connection in the mobile communication device; selecting the mobile radio connection with the best reception quality for the mobile radio communication, at least in a receiving direction; deriving different audio signals from the receive signals of the different mobile radio connections; and feeding the derived different audio signals to a delay circuit, which aligns transit time differences and/or the amplitude differences of the derived different audio signals with respect to one another, wherein the communication partner device of the mobile communication device is also equipped with two communication facilities configured to set up different communication connections, and wherein the receiving communication device, after receiving a call to initially set up a communication via a first mobile radio connection of the first communication facility:
(a) actively sets up a parallel second mobile radio connection via the second communication facility to the calling communication device, and(b) autonomously starts a callback to the calling communicating device via the parallel second mobile radio connection.
