Abstract:
A method of handling at least a call in handover in a wireless communication system and a communication device using the same are proposed. The wireless communication system includes at least a wireless communication network and a wireless communication device. The method includes the following steps. First, a wireless communication device receives a message for switching at least a packet-switched (PS) call to at least a circuit-switched (CS) call from the wireless communication network. Further, the wireless communication device sets a stream identifier of each of the CS calls to an identifier value. The method enables smooth single radio voice call continuity (SRVCC) handover from the PS call in one wireless communication network to the CS call in another wireless communication network. In addition, the method also enables SRVCC multicall handover from the PS call in one network operation mode to the CS call in another wireless communication network.
Abstract:
A method of handling data transmission associated with natural disaster notification for a mobile device of a wireless communication system includes activating a plurality of physical mediums for data reception in a radio resource control connected mode, and receiving a natural disaster notification message via at least some of the plurality of physical mediums.
Abstract:
A communication system, user device thereof, and a synchronization method thereof are provided. The communication system includes a user device and a wireless network. A ciphering configuration information is transmitted to a user device. The user device and wireless network re-establishing the radio link control (RLC) entity of logical link. The user device changes to the new ciphering configuration immediately following the re-establishment of RLC entity according to the received ciphering configuration information and the wireless network changes to the new ciphering configuration.

Abstract:
A method of RLC reconfiguration for a communication device of a wireless communication system includes receiving a dedicated signaling including a reconfiguration value corresponding to a RLC-related parameter when the RLC-related parameter is in-use, and not immediately starting to use the reconfiguration value on the in-use RLC-related parameter when the reconfiguration value is extracted from the dedicated signaling.
Abstract:
A method of handling inter-system handover security for a communication device in a wireless communication system includes creating a first security key set for security with a serving network, creating a second security key set with a deactivating state, receiving an inter-system handover command for an inter-system handover from the serving network to a target network, selecting either the first security key set or the second security key set during the inter-system handover, and using the selected security key set for security with the target network, wherein the selected security key set is identical with a third security key set that is used by the target network for security with the communication device.
