Abstract
Techniques for searching for wireless networks are described. In one scheme, a user equipment (UE) performs a manual search for detectable wireless networks while operating in a connected mode. The UE operates in the connected mode for communication with a wireless network and receives a request to search for detectable wireless networks. The UE performs a search for detectable wireless networks while operating in the connected mode, e.g., as background task during DRX time. In another scheme, the UE retains a search request received in an active state and performs a search at a later time after transitioning to an idle state. In yet another scheme, the UE efficiently handles a search across state transitions. The UE may cancel, suspend, resume, or continue the search after each transition from one state to another state based on the type of each state.
