A method of handling cell change for a mobile device employing a high speed downlink package access (HSDPA) technology in wireless communication systems. The method includes initiating a handover procedure to change a serving cell of the mobile device when the mobile device moves from a HSDPA cell into another HSDPA cell, performing a physical channel reconfiguration procedure from a high speed physical downlink shared channel (HS-PDSCH) to a dedicated physical data channel (DPDCH), wherein the physical channel reconfiguration procedure is initiated via a Radio Network Controller (RNC), and performing the handover procedure.

Method of handling cell change in wireless communication systems and communication device thereof

A method for adjusting ring volume through short message service includes steps of a communication device determining whether a volume adjusting condition is satisfied when there is a missed call; the communication device transmitting a first short message if the volume adjusting condition has been satisfied, wherein a first information element identifier (IEI) is set in the first short message and defined as a volume adjusting request in transfer protocol user data (TPUD) in advance; the communication device determining whether a second IEI is set in a second short message when receiving the second short message, wherein the second IEI is defined as a volume adjusting response in TPUD in advance; and the communication device selectively adjusting a ring volume thereof to maximum level if the second IEI is set in the second short message.
