  • Embedded MBMS status information reporting of idle UE in supporting LTE MBMS audience measurement
    Patent number: 8867410
    Abstract: A simple and effective mechanism is shown to determine and utilize information about idle user equipment which received MBMS services for purposes of audience monitoring. The implementation can be done by defining a new information element (IE) for a proposed MBMS status information and embedding the new IE into a UE-originated message of a network control signaling procedure, e.g., RRC Connection Request which may be sent at the convenience of the UE when it transitions from the idle state to the active state for its own purposes, i.e., purposes primarily other than audience monitoring.

  • Selection of connection type in cellular system
    Patent number: 8825040
    Abstract: The present invention presents a method and a controller for selecting the type of connection used to connect a terminal device to a serving base station. The connection type is selected on the basis of monitored communication-environmental parameters of the terminal device. The selection is made between a direct cellular radio connection and a relayed cellular radio connection. The relayed connection is established through another terminal device acting as a relay terminal for the connection being relayed. A direct device-to-device link between the two terminal devices is established as a cognitive radio connection, and a radio access technology and communication parameters of the device-to-device link may be negotiated between the terminal devices. The relay terminal then links the device-to-device link to a direct cellular radio connection between the relay terminal and the serving base station.

  • Operation in case of radio link failure
    Patent number: 8818381
    Abstract: Attempting recovery from an unexpected radio link failure. A backup user context is created for a terminal device served currently by a relay base station relaying a radio connection between the terminal device and fixed cellular network infrastructure including a fixed base station communicating with the relay base station, wherein the backup user context is prepared for use in case of an unexpected radio link failure. Upon detection of the radio link failure in a primary user context being used in the communication, the backup user context is applied before the terminal device enters an idle state as a result of the radio link failure.
