    Abstract: A method and apparatus for managing UE-based network performance measurements utilizing a process of tracing a UE in a radio telecommunication network. An eNB may receive a trace activation message from a Mobility Management Entity, MME, or a Network Management Entity, wherein the trace activation message includes eNB-specific, and optionally MME-specific, selection conditions for selecting a UE for a trace session. The eNB selects a UE for tracing when the eNB-specific selection conditions are satisfied, and may send the MME-specific selection conditions to the MME for evaluation. When all selection conditions are satisfied, the eNB activates the trace session with the selected UE. The Trace Activation IE utilized in the Trace Start message, the UE Context Setup Request message, and the Handover Request message is extended with additional IEs in order to implement the method.

    Abstract: Disclosed is an apparatus and method for transmitting/receiving a control message in a wireless communication system that is designed to reduce overhead associated with transmission/reception of the control message. To this end, a transmission apparatus generates a control message, generates a compressed control message by compressing the generated control message, based on a control message that has been lastly received by a reception apparatus from among previously transmitted control messages, selects one of the generated control message and the generated compressed control message according to whether or not the control message lastly received by the reception apparatus exists, and transmits the selected one of the generated control message and the generated compressed control message to the reception apparatus. Therefore, it is possible to reduce resources used for control message transmission, and thus increase the use efficiency of the resources.

  • Patent number: 8145198
    Abstract: The invention relates to a method of initializing an electronic radio communication module making it possible to execute a radio communication program, stored in a first non-volatile memory, the initialization being based on values of calibration parameters. According to the invention, the method comprises the following steps, performed by the module when it executes the program: reading (E11) of at least one compressed calibration parameter in a second non-volatile memory; decompressing (E12) each compressed calibration parameter read, so as to obtain a decompressed calibration parameter; and initializing (E14) the module, based on the values of the decompressed calibration parameters.

  • Patent number: 8131213
    Abstract: The present invention discloses a tagging and identification device and system for tracking and monitoring sea vessels as they enter sea ports, estuaries and/or other channels. The tagging device of the present invention comprises a receiver, for receiving an underwater electromagnetic signal transmitted by an underwater beacon. An acoustic transmitter is provided for transmitting an identification signal to an acoustic receiver deployed nearby. The acoustic identification signal is transmitted after an electromagnetic trigger signal is received from the underwater beacon. The tagging and device may further comprise a memory device which can store data relating to position and time of the see vessel to which it is attached. The tagging and identification device of the present invention is covert, compact and is capable of extended active deployment without replenishment of batteries etc.

  • Patent number: 8131216
    Abstract: Format converters and methods of performing data format conversion are provided. The format converters may convert compressed data into a different compressed format that is compatible with the Bluetooth transmission standard. The format converter may decompose the compressed data into frequency domain data streams of different frequency sub-bands. The format converter may transform each data stream of frequency domain information from a first encoding scheme to a second encoding scheme, and may then quantize the transformed data steams based on bit allocation information for each sub-band. The format converters may also include a bit allocation component which computes the bit allocation information for each sub-band based on an unfiltered version of the compressed data.

  • Patent number: 8046214
    Abstract: A multi-channel audio decoder provides a reduced complexity processing to reconstruct multi-channel audio from an encoded bitstream in which the multi-channel audio is represented as a coded subset of the channels along with a complex channel correlation matrix parameterization. The decoder translates the complex channel correlation matrix parameterization to a real transform that satisfies the magnitude of the complex channel correlation matrix. The multi-channel audio is derived from the coded subset of channels via channel extension processing using a real value effect signal and real number scaling.
