Abstract: Systems and methods for providing load based optimizations in communication networks are provided. A network device that provides network management and exchanges control messages with other network devices in the communication network can be modified to masquerade as a radio access transceiver to obtain radio access transceiver load information. The network device can be modified to include a radio-related interface and can communicate messages with the radio access transceivers to setup a radio access transceiver connection for exchange of load information. The radio access transceiver load information can then be used in the core network to provide optimizations for the loaded radio access transceivers. The optimizations can include modifying packet flows to decrease the bandwidth needed and switching one or more packet flows to another radio access transceiver.

Abstract: A broadband cellular network (BCN) provides a user equipment (UE) access to TVWS resources. The BCN authorizes the UE to access TVWS resources by conveying a mobile device identifier received from the UE, and a cell identifier associated with the UE's coverage area, to a Federal Communications Commission (FCC)-certified Database and receiving, from the Database, and storing an FCC ID associated with the UE and a set of available TVWS resources. The BCN then conveys, to the UE via a broadband cellular technology, a channel resource information element (CRIE) that includes the cell identifier and identifies the set of available TVWS resources. Subsequently, the BCN re-authorizes the UE to access TVWS resources based on the stored FCC ID and without re-conveying the mobile device identifier to the Database. The BCN further utilizes broadband cellular technology procedures to provide a “virtual” contact verification signal (VCVS) to the UE.

Abstract: A communication system that relays data messages from or to a plurality of remote endpoints via RF gateways to a data accumulation site over one of a series of communication channels. The communication system monitors the signal-to-noise ratio of communication from each individual endpoint, which can be utility meters and related control or monitoring points, to a gateway. Based upon a quality of service and/or the signal-to-noise ratio of the communication of the endpoints to the gateways, the system assigns a desired communication channel to the endpoint. Each of the desired communication channels have varying data transmission rate and required SNR and each channel is selected based upon the signal-to-noise ratio of the transmissions from the endpoint to the gateways. If the signal-to-noise ratio changes for an endpoint, the system dynamically reassigns a different channel to the meter based upon the updated signal-to-noise ratio.

Abstract: In one embodiment, an edge router of a local computer network snoops client-server protocol configuration information of a customer-premises equipment (CPE) device. From the snooping, the edge router may identify an Internet Protocol version 6 (IPv6) transition option in place at the CPE device along with associated configuration parameters for the IPv6 transition option. As such, the edge router may then advertise the IPv6 transition option along with associated configuration parameters to one or more border/relay routers of the local computer network to cause the one or more border/relay routers to provision themselves with the IPv6 transition option and associated configuration parameters.

Abstract: The present disclosure provides a fabric ingress scheduler and method that distributes ingress packet traffic in a time division multiplex (TDM) system, both fabric interface aggregate and per connection, deterministically across fabric paths. Advantageously, the fabric ingress scheduler and method minimizes fabric latency and prevents fabric interface head-of-line blocking. The fabric ingress scheduler and method utilizes the fact that each connection flow has a known maximum rate which must be reserved through the fabric for prevention of data loss (essentially circuit switching using a packet fabric). In exemplary embodiments, the fabric interface supports per packet fabric path selection. Generally, the fabric ingress scheduler and method generally provides a deterministic scheduling of ingress packets to fabric paths.
