Abstract
A device creates a list of permanent evolved packet system (EPS) mobility management (EMM) failure events associated with the device, where the list includes information associated with one or more permanent EMM failure events encountered by the device. The device stores the list of permanent EMM failure events, provides an attach request message to an access network, and receives, from the access network, a reject message as a response to the attach request message. The device performs a power cycle based on receiving the reject message, and erases, based on the power cycle, a forbidden public land mobile network (PLMN) list and a forbidden tracking area list maintained by the device. The device repopulates the forbidden PLMN list and the forbidden tracking area list with information included in the list of permanent EMM failure events.
