Methods for call management with multiple subscriber identity cards and apparatuses using the same

摘要

An embodiment of a method for call management, performed by a processing unit (240) of a UE (user equipment), is disclosed. The method is employed in a hardware configuration of at least two subscriber identity cards sharing a radio resource. A PS (packet-switched) service is first provided for the first subscriber identity card (250a). Packet data transmission and reception is handed over to a second PS service with the second subscriber identity card (250b) from the first PS service after receiving a call request requesting a CS (circuit-switched) service with the second subscriber identity card.
