A wireless mobile terminal determining a size of an advertised window depending on a current data rate of a wireless downlink transmission is provided. The wireless mobile terminal receives from a transmission control protocol (TCP) sender a data packet comprising a header portion and a payload portion; and determines the current data rate of the wireless downlink transmission to the wireless mobile terminal from signaling information contained in the header portion of the data packet; and determines the size of the advertised window depending on the current data rate of the wireless downlink transmission.

Wireless mobile terminal and telecommunication system

A method of handover between two WLAN cells based on the IEEE 802.11 standard and working at two different frequencies, the method including the step of performing measurement(s) on the second frequency in order to verify the necessity or the opportunity to realise a handover, the first frequency being currently used to transmit data, the method characterised in that it involves: first sending at least one dummy data or control frame on the first frequency which is currently used for transmitting data, the data or control frame including a duration data with a value at least equal to the time needed to perform the measurement(s) at the second frequency, and, then performing the measurement(s) on the second frequency.

Method for improving handovers in a WLAN

The present invention relates to a method of selecting of a path to establish a communication link between a first node and one of a plurality of access points of a wireless cellular telecommunication system, the wireless cellular telecommunication system having second nodes being adapted to serve as relay nodes. The method comprises the steps of receiving of data from at least one of the second nodes, the data being indicative of a first quality measure of a first path from the one of the second nodes to its access point, comparing of a second quality measure of a second path from the first node to its access point with the first quality measure, selecting of the first path to replace the second path if the first quality measure is superior to the second quality measure.
