Method, communications system, central interface device and mobile terminal for operating a wireless communication link

摘要

The method involves prioritizing a voice data transmission according to IEEE 802.11 standard, and measuring a variable indicating the quality of a radio connection. A message is transmitted to a central interface device located between a local area network and a switched telephone network. The message is used to decide a changeover of an existing voice data communication connection from a radio coverage area to another area. The changeover is initiated in response to the decision by a mobile radio transmitting/receiving device. Independent claims are also included for the following: (1) a communication system comprising a stationary radio transmitting/receiving device (2) a mobile terminal operated according to IEEE 802.11 standard.
