Data flow control in WLAN radio connections for the impairment of internet telephony
First Claim
Patent Images
1. A method for controlling the data flow in a radio link between a wireless local area network (WLAN) base station and a WLAN mobile station with the radio link having synchronous data traffic and asynchronous data traffic, comprising:
- a) providing that the synchronous data traffic requires that delay times on the channel remain below a certain delay time threshold, andb) reducing the data rate of the synchronous data traffic on the radio link for a time period at time intervals, in order to restrict the synchronous data traffic, wherein the reducing comprises deliberately delaying the data on the radio link by a delay time greater than the certain delay time threshold.

Abstract
In a method for controlling the data flow on a radio link between a WLAN base station and a WLAN mobile station, the data rate on the radio link is reduced for in each case one time period (36, 37) at time intervals (35). One preferred field of application for the method is to restrict general or unauthorized transmission of a telephone call via the Internet.

13. An apparatus for controlling the data flow on a radio link between a wireless local area network (WLAN) base station and a WLAN mobile station, with the radio link having synchronous data traffic and asynchronous data traffic, the apparatus comprising:
-
means for providing that the synchronous data traffic requires that delay times on the channel remain below a certain delay time threshold, and means for reducing the data rate of the synchronous data traffic for in each case one time period at time intervals, in order to restrict the synchronous data traffic, wherein the means for reducing includes means for deliberately delaying the data on the radio link by a delay time greater than the certain delay time threshold. - View Dependent Claims (14, 15)
