  • Patent number: 10708148
    Abstract: Many services measure quality of service (QoS) according to abstract metrics based on general heuristics of QoS determinants (e.g., VoIP service providers may presume that QoS is predominantly determined by network performance). However, users' QoS perceptions are often based on their experiences with particular activities of the service, which may utilize different service paths having different QoS determinants. Therefore, QoS may be measured by identifying the activities of the service, and the dependencies among the components of such services; for respective activities and dependencies, identifying a service path from the source to the user, and the segments comprising the service path; measuring the quality of the segments of the service path; and calculating the QoS of the activity according to the QoS of the segments of the service path providing the activity. This approach may yield QoS information of greater relevance to the users' experience and with greater analytic value.

  • Patent number: 10708170
    Abstract: A request for a chunk of data is received from an application executing on a remote device. The chunk of data is split into a plurality of packets including a first packet and a second packet. A first sub-flow is selected to transport the first packet to the remote device and a second sub-flow is selected to transport the second packet. The first sub-flow is decoupled from the second sub-flow. A first stop time is selected for the first sub-flow and a second stop time is selected for the second sub-flow. The first stop time determines when the first sub-flow will complete at the remote device and the second stop time determines when the second sub-flow will complete at the remote device. The first stop time and the second stop time are selected so that the first sub-flow and the second sub-flow will complete simultaneously at the remote device.

  • Patent number: 10681397
    Abstract: A method of preparing data streams to facilitate seamless switching between such streams by a switching device to produce an output data stream without any switching artifacts. Bi-directional switching between any plurality of data streams is supported. The data streams are divided into segments, wherein the segments include synchronized starting points and end points. The data rate is increased before an end point of a segment, to create switch gaps between the segments. Increasing the data rate can include increasing a bandwidth of the plurality of data streams, for example by multiplexing, or compressing the data. The present invention can be used, for example, with MPEG or AC-3 encoded audio and MPEG encoded video segments that are multiplexed into MPEG-2 transport streams. Also included are specific methods for preparing MPEG video streams and multiplexing MPEG video with MPEG or AC-3 audio streams to allow a receiver to create seamless transitions between individually encoded segments.

  • Patent number: 10680939
    Abstract: Systems and methods of mesh network communication enabling a relay node to autonomously select a packet propagation mechanism. Upon receiving a packet, which may carry an indication for flooding propagation as set by the edge node originating the packet, or carry no specification for any propagation mode, the relay node determines whether the packet is eligible for routing-propagation based on a number of factors, such as whether there is an existent valid route from the source node to the destination node, whether the packet is originated from a friend edge node, and whether a route discovery process has been initiated. Accordingly, the relay node may change the indication to routing propagation and forward it by routing-relaying. Thus, the packet can be propagated over the mesh network by routing propagation, despite the initial setting for flooding propagation as specified by the edge node or no setting by the edge node.

  • Patent number: 10681592
    Abstract: When a UE is served by a first radio access network (RAN) and is engaged in a voice call such as a VoIP call, a determination will be made that the UE is at an edge of coverage (e.g., threshold poor coverage) of the first RAN and that there is no other adjacent coverage of the first RAN that could support the voice call. In response, signaling will cause a second RAN to page the UE via the first RAN so as to cause the UE to transition from being served by the first RAN to being served by the second RAN. More generally, when a UE has poor coverage of its serving RAN, another RAN will pull the UE to the second RAN by paging the UE to trigger transition of the UE from to the second RAN.

  • Patent number: 10660033
    Abstract: Methods, systems, and devices are described for wireless communication at a UE. A user equipment (UE) may perform an initial access procedure to establish a connection with a serving cell. The UE may then arrange a regular transmission schedule with the serving cell including a discontinuous transmission (DTX) cycle and an acknowledgement schedule. The UE may enter a low power mode and refrain from any transmission during the a sleep interval of the DTX cycle. The UE may then wake up and transmit a message to the serving cell after the sleep interval without performing another access procedure. The UE may perform another access procedure to transmit at times not covered by the regular transmission schedule. For example, if an acknowledgement (ACK) for the message isn't received, the UE may perform another access procedure for retransmission.

  • Patent number: 10652762
    Abstract: Enhanced quality of service of a cellular radio access network is provided by monitoring the operation of the network for predicting failures. For each of the predicted failures, a proactive maintenance plan is created and an alternative network configuration determined, in which alternative network configuration the impact of the planned maintenance operations is less than in the current (non-alternative) network configuration. Additionally, timing of the maintenance operations is decided based on a network traffic estimate and the network is automatically reconfigured into the alternative network configuration prior to the selected maintenance operation time. According to an embodiment, the object is achieved by means of a Pre-emptive Maintenance Node (PEM) connected to the telecommunications network, such as to an LTE or LTE-A network.
