  • Patent number: 9954639
    Abstract: The present invention provides a method for controlling transmission of a signal between a transmitter and a receiver during a phase of change of a signal data rate. The method comprises, when the change is requested, informing the transmitter and receiver of a start of a transition phase. The transmitter retransmits the signal N times, with N?1, in identical signal parts having a chosen length. The receiver stores the N retransmitted identical signal parts successively received to combine them together to produce a combined signal part, and to temporarily output these combined signal parts with an auxiliary data rate depending on N and on this signal part length. The transmitter and the receiver are informed of the end of the transition phase when the signal data rate change is finished.

  • Patent number: 9949110
    Abstract: A call loop avoidance capability is provided for preventing formation of a call loop resulting from handling of a mobile terminated (MT) call in parallel with a location update for a mobile device (MD) in a wireless communication network. The call loop avoidance capability prevents formation of a call loop between an old mobility and call management entity (MCME) and a new MCME when delivery of an MT call to an MD is performed while the MD is in the process of moving from the old MCME to the new MCME using a location update procedure. An enhanced call routing procedure supports direct delivery of the MT call from the new MCME to the MD (rather than delivery of the MT call by the new MCME to the MD via the old MCME) in order to prevent formation of a call loop between the old MCME and the new MCME.
