Abstract:
1. A method for establishing a connection by a scanner device to a paging device over a sequence of hop channels, the method comprising the steps of prior to establishing a connection between the scanner device and the paging device, repeatedly activating the scanner device; selecting by the scanner device a hop channel from the sequence of hop channels as a function of a present phase when the scanner device is activated; determining by the scanner device whether the selected hop channel is a forbidden hop channel, wherein said determining step further comprises the steps of monitoring interference on the selected hop channel and deciding that the selected hop channel is a forbidden hop channel when the monitored interference exceeds a threshold value; if the selected hop channel is a forbidden hop channel, then selecting by the scanner device a substitute hop channel from the sequence of hop channels as the selected hop channel; monitoring, by the scanner device, the selected hop channel for receipt of a paging message from the paging device during the present phase; and establishing a connection from the scanner device to the paging device in response to receipt of the paging message.
