  • Patent number: 10687181
    Abstract: An electronic apparatus includes a communication unit that performs wireless communication which uses an internal access point, a processing unit, and a display unit. In a state where the number of terminal apparatuses that establish a wireless connection to the internal access point reaches an upper limit value, in a case where a wireless connection request is received from a terminal apparatus that does not establish a wireless connection, the processing unit rejects the wireless connection request and performs processing that displays an alert in a first display mode on the display unit. Moreover, in a case where, until a given period of time has elapsed after the alert was kept non-displayed, the wireless connection request is again received from the terminal apparatus, the processing unit performs processing that sets a mode for displaying the alert to be a second display mode.

  • Patent number: 10667244
    Abstract: When a base station is capable of using multiple different types of waveforms for a downlink communication to a UE, the UE may waste processing resources attempting to receive and/or process the downlink communication. For example, the UE may cycle through various possible types of waveforms in an attempt to process the downlink communication. Techniques described herein use waveform signaling for downlink communications to notify the UE of a type of waveform being used for a downlink communication, thereby conserving UE resources (e.g., processing resources, memory resources, RF resources, and/or the like) that would otherwise be wasted attempting to process the downlink communication using multiple types of waveforms.

  • Patent number: 10666550
    Abstract: A method for determining a termination point of at least one tunnel or segment in a packet switching network. The network includes a set of routers and links between them, the routers and links forming a previous network topology, a transit router receiving packets intended for an output router, an event modifying the previous topology into a subsequent network topology, and a backup path between the transit router and the output router being calculated for the subsequent topology. The method includes calculating, prior to the event, for each router, an initial tree based on the previous topology, which has as a root the router and has as branches paths of minimum cost between the root and the other routers. A termination point of a tunnel or segment is obtained to prevent packets transiting between the start router and the output router from entering into a micro-loop caused by the event.

  • Patent number: 10652159
    Abstract: A mobile communications system includes a transceiver and a packet subsystem server of a mobile communications network for the transceiver. The transceiver can transceive wireless signals with mobile devices in a coverage area using wireless connections to exchange data with application servers. For each wireless connection the packet subsystem server can determine weighted scores using different weights for each of direct radio measures, a packet retransmission rate of the mobile communications network, and a throughput data rate. The packet subsystem server can determine an aggregated score from the weighted scores and determine a data-rate-control decision for the wireless connection using the aggregated score. The data-rate-control decision can be outputted to a packet core handling system of the mobile communications network for controlling the data rate of data transmitted using the wireless connection.
