A communication device is provided that includes a receiver configured to receive a signal. The communication device further includes a determination circuit configured to determine an energy level of the signal and to decode the signal as voice or encoded data. The communication device further includes at least one processor configured to generate an instruction to mute or unmute an audio output based on the energy level of the signal in a predefined audio frequency range.

Communication device and method for audio encoded data radio transmission

A method () and user equipment () that are for operation in a wireless communication system () maintain system state synchronization between a fixed network () of the wireless communication system and the user equipment by performing a receipt () of a message from a network station () while the user equipment is in a connected state (); a determination () that the message includes an address of the user equipment and that the message is a message that should not be generated while the fixed network has the user equipment logged as being in the connected state; and a switching () of the user equipment to an idle state ().

Apparatus and method for operational state synchronization in a wireless communication system

A method for facilitating synchronization between a communications network () and a wireless communications device () operating in a Continuous Packet Connectivity, CPC, discontinuous transmission, DTX, mode, comprises monitoring () at the wireless communications device () the radio conditions of downlink communications using control bits received from the communications network () to determine when the wireless communications device () is at a nearly out of synchronization state with the communications network (). In response to determining the wireless communications device () is at a nearly out of synchronization state, the wireless communications device () sends () to the communications network (), additional control information on a control channel. The wireless communications device () receives () additional control bits sent by the communications network () in response to the communications network () receiving the additional control information sent by the wireless communications device ().

Method for facilitating synchronisation between a communications network and a wireless communications device operating in a CPC DTX mode and a wireless communications device

A method of implementing security in a wireless communication device () comprises receiving (), at the device (), a security mode command for activating a security mode in the device and storing a sequence number of the received security mode command. A security mode complete or failure message is sent () based on whether a security mode is activated in the device. An acknowledgement of the security mode complete or failure message is received () and a timestamp of the acknowledgement is stored. On receiving a PDU, sequence numbers and timestamps of segments of the received PDU are compared () with the stored sequence number and timestamp of the acknowledgement. The received PDU segments are managed () in response to the comparisons, and the sending of the security mode complete or security mode failure message. A wireless communication device is also disclosed.

Security in wireless communication system and device

Disclosed are mobile communication devices and methods of a mobile communication device that determines that no response has been received within a predetermined period of time from a network to a transmission of an encoded data block in accordance with a commanded MCS. The device then determines an alternative MCS capable of coping better with variations in the radio environment with minimal damage or alteration than the commanded MCS and preemptively transmits the encoded data block in accordance with this more robust alternative MCS. In this way the mobile communication device does not continue failed attempts to transmit data in accordance with the commanded MCS. After the device receives notice of successful transmission of the encoded data block with the alternative MCS, the device will resume the use of the commanded MCS to transmit subsequent encoded data blocks.

A method of selecting a communication system () for operating with a communication device () during an idle mode of operation of the communication device is described. The communication device () is capable of operating with at least two communication systems. The method comprises determining () the one communication system of the at least two communication systems () with which the communication device () has a smallest power consumption when operating in the idle mode of operation, and selecting the determined one communication system for operation with the communication device during the idle mode of operation.
