Abstract: A mobile phone comprises a display and a touch panel that is provided on the display, and is capable of setting a locked state. In a case where the locked state is set, a lock screen including the lock object is displayed on the display. If a long-depressing touch operation is performed to the lock object, shortcut icons corresponding to a telephone function, etc. are displayed on the display instead of the lock object. If the shortcut icon of the telephone function, for example, is selected by a selecting object corresponding to a touch position in the shortcut screen, the locked state is canceled and the telephone function is performed.

A radio link having the same PSC as that reported by user equipment (UE) may be created on some or all internal cells which are chosen based on radio frequency (RF) proximity to a serving cell of the UE or one or more iterations of a PSC resolution set selection process. If the UE is reporting the PSC of one of these cells, the UE and a Node Bs will be able to successfully complete a synchronization procedure to add one of the radio links to the UE's active set, while any remaining created radio links can be deleted. After a certain number of successful radio link additions, the combination of the PSC and active set may be considered to be resolved, therefore, negating a need to resolve the PSC in subsequent soft handover requests.
