ABSTRACT:
A method for operating a wireless communication connection comprising a first device using a first standard for LANs and providing a first radio coverage area, a second device operating according to a second standard and providing a second radio coverage area, the first and the second coverage areas overlapping, a mobile device operable according to the first and the second standards and a central interface device between the LAN and a switched telephone network, a voice data transmission according to the first standard is prioritized by the mobile device. A measurement is performed and a message including the measurement result and topology information relating to the LAN is transmitted to the central device. The central device uses the message to decide for a changeover of the operation of an existing connection from the first area to the second area, the mobile device initiating the changeover based on the decision.
