  • Publication number: 20240007956
    Abstract: Apparatuses, systems, and methods for application aware cellular radio activation/deactivation, e.g., in 5G NR systems and beyond. The UE may receive, while operating in a power savings mode in which a cellular modem of the UE is disabled, inputs associated with an application of the UE. The UE may determine, based on the inputs, to activate the cellular modem to support the application of the UE. The inputs may include an indication of an application state or status, an indication of an application category, an indication of a state or status of an AI assistant of the UE, an indication of whether an application is a session application, an indication of network assertions, an indication of proximity information, an indication of a WiFi state or a WiFi status, and/or indications associated with one or more timers.

  • Patent number: 8107370
    Abstract: Access devices and methods according to the invention interconnect digital devices and a network. Setting a parameter associated with each input port of an access device specifies whether the device connected with that port is restricted or unrestricted. When a particular input port is restricted, packet detectors examine the packets received on that port. In some embodiments, an exception handler handles restricted packets from restricted devices in an advantageously flexible manner. In other embodiments, a controller receives a configuration command and sets the restriction parameters accordingly. The invention provides a simple, abstract, easy to use, and flexible tool for network management, configuration, and reconfiguration.

  • Patent number: 8082333
    Abstract: A DHCP proxy agent is provided to send on behalf of a static host a DHCP request so that an access layer security feature such as DHCP snooping/IPSG can be applied to the static host and/or in a mixed static IP and DHCP environment.

  • Patent number: 7385977
    Abstract: A method and apparatus for a downstream router to inform an upstream router by use of packets of a new router command protocol that the upstream router is to forward multicast packets of a specified group to the downstream router. First the downstream router transmits a HELLO packet to upstream router to inform the upstream router that the downstream router is a multicast router implementing the invention. Then, in the event that the downstream router receives a packet from an end station requesting multicast packets of a particular group, in response the downstream router sends a JOIN packet to the upstream router. The JOIN packet requests that the upstream router forward the requested group multicast packets to the downstream router. When a multicast group packet arrives at the upstream router, the upstream router forwards the packet to those downstream routers requesting that group.

  • Patent number: 6847638
    Abstract: A method and apparatus for a router to inform a Layer 2 switch by use of packets of a new router group port management protocol (RGMP) that the layer 2 switch is to forward multicast packets of a specified group to the router. First the router transmits a RGMP HELLO packet to the layer 2 switch to inform the switch that the router is a multicast router implementing the invention. Then, in the event that the router receives an IGMP packet from an end station requesting multicast packets of a particular group, in response the router sends an RGMP JOIN packet to the layer 2 switch. The RGMP JOIN packet requests that the layer 2 switch forward only multicast group packets, of the group whose group number is written into a field of the RGMP JOIN packet, to the router. Also, the router sends a prior art PIM JOIN packet to other multicast routers in order to be placed on the multicast distribution tree for that group.
