1. A method for controlling a wireless terminal, the method comprising:
- a) transitioning from a hibernation mode to a wake mode;
b) communicating with a first wireless network during a first waking period having a first duration;
c) communicating with a second wireless network during a second waking period following the first waking period;
d) detecting that the second wireless network is different from the first wireless network; and
e) extending the second waking period to a second duration greater than the first duration in response to detecting that the second wireless network is different from the first wireless network.

Abstract
A method for controlling a wireless terminal operating in a hibernation cycle alternating between a wake mode and a hibernation mode includes communicating with a first wireless network during a first waking period having a first duration, and with a second wireless network during a second waking period following the first waking period. The second waking period is extended to a second duration, greater than the first duration, responsively to detecting that the second wireless network is different from the first wireless network. Network information relating to the second wireless network is received during the second waking period.

7. A wireless terminal comprising:
-
a) a transmitter configured to transmit information to first and second wireless networks; b) a receiver configured to receive information from the first and second wireless networks; and c) a control module configured to control the transmitter and the receiver to; i) alternate between a wake mode and a hibernation mode so as to communicate with the first wireless network during a first waking period having a first duration, ii) communicate with the second wireless network during a second waking period following the first waking period, iii) detect that the second wireless network is different from the first wireless network; and iv) extend the second waking period to a second duration greater than the first duration in response to detecting that the second wireless network is different from the first wireless network. - View Dependent Claims (8, 9, 10, 11, 12)
