  • Publication number: 20220132449
    Abstract: A method corrects the time defined by an internal clock of an entity capable of receiving signals from a satellite positioning system and of communicating with at least one other entity. When the signals do not allow the satellite positioning of the entity, the method includes: receiving, by the entity, a message originating from the other entity, the message including a first piece of time data associated with the instant the message was transmitted; determining, by the entity, a second piece of time data associated with the instant the message was received by the entity; calculating a time difference between the second piece of time data and the first piece of time data; and then, when the time difference is negative, determining a time correction to be made to the internal clock of the entity.

  • Patent number: 9503981
    Abstract: A method (300) and user equipment (110) that are for operation in a wireless communication system (100) maintain system state synchronization between a fixed network (130) of the wireless communication system and the user equipment by performing a receipt (305) of a message from a network station (105) while the user equipment is in a connected state (220); a determination (310) 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 (315) of the user equipment to an idle state (215).

  • Patent number: 9088940
    Abstract: A method for facilitating synchronization between a communications network (102) and a wireless communications device (104, 106, 200) operating in a Continuous Packet Connectivity, CPC, discontinuous transmission, DTX, mode, comprises monitoring (304) at the wireless communications device (104, 106, 200) the radio conditions of downlink communications using control bits received from the communications network (102) to determine when the wireless communications device (104, 106, 200) is at a nearly out of synchronization state with the communications network (102). In response to determining the wireless communications device (104, 106, 200) is at a nearly out of synchronization state, the wireless communications device (104, 106, 200) sends (310) to the communications network (102), additional control information on a control channel.

  • Patent number: 8995664
    Abstract: A method of implementing security in a wireless communication device (108) comprises receiving (300), at the device (108), 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 (302) based on whether a security mode is activated in the device. An acknowledgement of the security mode complete or failure message is received (304) and a timestamp of the acknowledgement is stored. On receiving a PDU, sequence numbers and timestamps of segments of the received PDU are compared (306) with the stored sequence number and timestamp of the acknowledgement. The received PDU segments are managed (308) 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.

  • Patent number: 8837519
    Abstract: 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.
