Patent ID: 8400949

Claim:
A method, comprising: at a device, determining that a wirelessly received signal is scrambled by a scrambling code which is not within a list of scrambling codes received from a serving network node; and at the device, applying a rule to determine from the scrambling code whether to decode broadcast system information that is transmitted by an access node using the scrambling code; wherein the rule comprises at least one of: if the scrambling code is not within the locally stored list received from the serving network node, do not decode the broadcast system information again if the scrambling code is locally stored from a previous instance of decoding the system information; and, if the scrambling code is not within the locally stored list received from the serving network node, do not attempt to decode the system information unless a measured signal strength for the wirelessly received signal is higher than a threshold, in which the threshold is one of: absolute; and dependent on strength of a signal received from the serving network node.
