Patent Images
1. A method for execution by a wireless device supporting a plurality of RATs (radio access technologies), the method comprising:
- while in a current cell;
(a) receiving, from the current cell, first neighbour information indicating frequency and RAT of at least one neighboring cell; and
(b) receiving, from a neighbour cell that neighbours the current cell, second neighbour information indicating frequency and RAT of at least one neighboring cell of the neighbour cell;
determining at least one frequency used for a first RAT based on the first and second neighbour information; and
scanning for a network using the first RAT or a second RAT based on the at least one frequency used for the first RAT.

Abstract
A wireless device receives neighbor information broadcasted by a current serving network. The neighbor information includes frequency information of neighbors and overlay RAT (radio access technology). According to an embodiment of the disclosure, the wireless device avoids various frequency blocks when scanning for a RAT when it is known from the neighbor information that those frequency blocks are used for a different RAT. Those frequency blocks can either be skipped altogether or scanned only after other frequency blocks are scanned. Therefore, the amount of network scanning can be reduced.
