Abstract
A wireless communication unit comprises a receiver operably coupled to a signal processing function arranged to make a hand-over determination based on a communication signal received from a serving communication station. The signal processing function is arranged to perform a hand-over operation based on at least one quality of service metric(s) obtained from a medium access control layer of a received signal.
The embodiments comprise identifying an optimal hand-over candidate that enables a more effective hand-over from a first WLAN to a second WLAN or a cellular system.

40. A wireless communication unit comprising:
a receiver operably coupled to a signal processing function arranged to make a hand-over determination based on a first communication signal received from a serving communication station and a second communication signal received from one or more candidate serving stations, wherein the signal processing function is arranged to predict whether an available bandwidth provided by the one or more candidate serving stations is sufficient to meet a future communication need of the wireless communication unit and performs a hand-over operation based on at least one quality of service metric(s) obtained from a medium access control (MAC) layer of the first received signal from the current serving communication unit and the predicted available bandwidth provided by the one or more candidate serving stations. - View Dependent Claims (41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58)

59. A method of handing over communication from a first wireless serving station to a second wireless serving station, the method comprising the step of:
-
receiving a first communication signal from a serving communication station; and receiving a second communication signal from one or more candidate serving station; decoding the first communication signal to identify at least one quality of service metric(s) obtained from a medium access control layer of the received first communication signal; decoding the one or more second communication signal to predict whether an available bandwidth provided by the one or more candidate serving station is sufficient to meet a future communication need of the wireless communication unit; and making a hand-over determination based on the predicted available bandwidth provided by the one or more candidate serving station and the at least one quality of service metric(s) obtained from a medium access control layer of the first received signal.
