Method and apparatus for network scanning based on neighbor information

摘要

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.
