  • Patent number: 9832681
    Abstract: Methods and devices for reducing traffic over a wireless link through the compression or suppression of high layer packets carrying predictable background data prior to transportation over a wireless link. The methods include intercepting application layer protocol packets carrying the predictable background data. In embodiments where the background data is periodic in nature, the high layer packets may be compressed into low-layer signaling indicators for communication over a low-layer control channel (e.g., an on off keying (OOK) channel). Alternatively, the high layer packets may be suppressed entirely (not transported over the wireless link) when a receiver side daemon is configured to autonomously replicate the periodic background nature according to a projected interval. In other embodiments, compression techniques may be used to reduce overhead attributable to non-periodic background data that is predictable in context.

  • Patent number: 9559980
    Abstract: Constraining resource provisioning by domain controllers based on resource requirements projected for remotely-originating inter-domain traffic can improve utilization efficiency and link reliability in multi-domain software defined network (SDN) architectures. A domain controller may be required to reserve a portion of inter-domain link capacity for transporting remotely-originating traffic. This may limit the inter-domain link capacity available for transporting locally-originating traffic in a manner that ensures remotely-originating traffic flows have equitable and/or adequate access to resources of inter-domain links. Alternatively, a domain controller may be required to maintain a minimum throughput rate for remotely-originating traffic, which may cause remotely-originating traffic to be prioritized over locally-originating traffic when necessary to maintain the minimum throughput rate. Provisioning constraints can be generated in a centralized or distributed fashion.

  • Publication number: 20160323914
    Abstract: Diverse traffic types can be efficiently communicated in a simultaneous manner by dynamically selecting between contention-based and scheduling-based media access control (MAC) communication schemes. Such a mechanism may be particularly beneficial in networks having a contention-based access resources and scheduling based access resources. Contention-based resources and scheduling based resources may occur over a common period, and may be orthogonal in the frequency domain and/or in the code domain. The dynamic selection may be based on a traffic characteristic or a network characteristic, and may be performed on a packet-by-packet basis. The selection criteria may be updated dynamically to adapt to changing network conditions, and may be communicated to the various transmitters via control channels or higher layer signaling.

  • Publication number: 20160270119
    Abstract: In a wireless (e.g., machine-to-machine) network, items of user equipment compete for wireless communication resource slots (“resources”). In a contention period, an item of user equipment (a UE) sends a first signal to a base station using a first resource. The first resource is mapped to a second resource in a data transmission period. If the base station successfully receives the first signal, it sends a second signal to the UE to confirm that the UE has been awarded the second resource and can transmit data in the data transmission period.
