  • Patent number: 12156271
    Abstract: A method for expedited tunnel establishment with a non-Third Generation Partnership Project (3GPP) interworking gateway to access a 3GPP network is provided. A User Equipment (UE) initiates establishment of an Internet Protocol secure (IPsec) tunnel with a first non-3GPP interworking gateway associated with the 3GPP network. The UE probes availability of a second non-3GPP interworking gateway associated with the 3GPP network before the IPsec tunnel with the first non-3GPP interworking gateway is established successfully. The UE initiates establishment of an IPsec tunnel with the second non-3GPP interworking gateway in response to failing to establish the IPsec tunnel with the first non-3GPP interworking gateway and the second non-3GPP interworking gateway being available. The UE accesses the 3GPP network over the IPsec tunnel with the second non-3GPP interworking gateway.

    Abstract: A method and apparatus for video coding using Intra prediction are disclosed. In one method, a first prediction sample in an immediately right column of the current block and a second prediction sample in an immediately below row of the current block are derived using angular prediction. The first prediction sample and a left column reference sample in the same row as the first prediction sample are interpolated to generate a horizontal predictor. The second prediction sample and an above-row reference sample in the same column as the second prediction sample are interpolated to generate a vertical predictor. The vertical predictor and the horizontal predictor are linearly combined to generate an angular-planar prediction sample. In another method, a first predictor is generated using angular prediction and a second predictor is generated using planar prediction. The first predictor and the second predictor are linearly combined to generate a fused Intra predictor.
