  • Patent number: 10484905
    Abstract: A user equipment (UE) and associated method performs a voice call with a network, including exchanging voice packets, determines an uplink data transmission to be performed concurrently with the voice call and stores the uplink data transmission in a buffer. A base station and associated method performs a voice call with a UE, determines a downlink data transmission for the UE is to be performed concurrently with the voice call and stores the downlink data transmission in a buffer when the UE is a predetermined type. A UE and associated method associates with a first access point (AP), determines first performance characteristics of a connection with the first AP, determines second performance characteristics of a potential connection with a second AP, declares a radio link failure when the second performance characteristics exceed the first performance characteristics to trigger a handover procedure from the first AP to the second AP.

  • Patent number: 10484252
    Abstract: A single high-speed bus accommodates both low-rate and high-rate bi-directional signal traffic by interleaving the traffic at the two rates sequentially so that all the data in the bus at any given time is either high-rate or low-rate. The interleaving is executed by a statistical aggregator according to a policy tailored to the traffic expected in the particular bus. The policy may be static and predetermined, or it may be dynamic and adaptive. Adaptive policies are continually updated with predictions of future traffic based on the statistics of past and/or present traffic. The technique may be implemented in both on-chip and system-level bus interfaces.

  • Patent number: 10462032
    Abstract: A method is described of probing a network route using a pairs of probe packets in which the first packets are typically smaller than the second. A first pair of probe packets with size ratio [L1/L2] and a second pair of probe packets with different size ratio [M1/M2] are transmitted onto a network route. An indicator of time taken for the second probe packet in the packet pairs to traverse the network route is derived and it is identified whether the values of the derived indicators vary or are substantially the same. The method, which can be used to probe home or domestic networks, indicates whether the first link in the route is or is not a bottleneck link, thereby providing further information about the route. A test apparatus, gateway device and computer to perform the method are also disclosed.

  • Patent number: 10420019
    Abstract: Described herein are devices, components, and techniques for performing cell discovery by a cellular communication device. Prioritization data is stored by the communication device indicating, for each of multiple geographic regions, the bandwidths of frequency bands that are potentially available to the communication device. The communication device determines an order in which to search the frequency bands based on this prioritization data. For example, frequency bands having relatively high aggregate bandwidths may be prioritized over frequency bands having relatively lower aggregate bandwidths. In some cases, the priority of the frequency bands may be determine algorithmically based on the bandwidths of the frequency bands, and in some situations a lower bandwidth band may be prioritized over a higher bandwidth band.
