Abstract
A network reselection procedure, of a wireless communication device, that occurs following a network detachment event, such as a device sleep event or a device power savings mode event. The wireless communication device attempts to acquire a first wireless network to which the wireless communication device was most recently attached, immediately preceding the network detachment event. Then, in response to an unsuccessful acquisition of the first wireless network, the wireless communication device attempts an alternate network acquisition utilizing a Most Recently Used List (MRUL) that is stored at the wireless communication device and includes information about one or more frequency bands allocated to a primary service provider with which the wireless communication device is affiliated. After determining whether the alternate network acquisition attempt was successful, the wireless communication device attaches to a second network and stores information associated with the second network.
