  • Patent number: 9769219
    Abstract: A terminal management system transmits identification information for identifying a first communication terminal to one or more of a plurality of communication terminals, in response to receiving from the first communication terminal a notification that the first communication terminal is waiting to be registered as a candidate counterpart communication terminal. In response to receiving, from a second communication terminal of the one or more of the plurality of communication terminals, a request for adding the first communication terminal as a candidate counterpart communication terminal of the second communication terminal, the terminal management system stores the identification information of the first communication terminal in association with identification information of the second communication terminal to register the first communication terminal as a candidate counterpart communication terminal of the second communication terminal.

  • Patent number: 9763112
    Abstract: A communications system having a network of nodes that may transmit and receive wireless signals. RF channel quietness may be measured at each node. A channel that is the best for all of the nodes may be selected. However, if all of the nodes except for one node determine that a particular channel is the best and not acceptable to the one node but that another channel is acceptable to all of the nodes, then the entire network may choose to operate on the other channel. The network may choose to operate on more than one channel in a time slotted fashion if a single acceptable channel cannot be found for all of the nodes. Channel quietness measurements may be facilitated by and uploaded to a host controller. The host controller may build a profile of measurements from the nodes for each channel.

  • Patent number: 9749774
    Abstract: In order to minimize traffic on a Zigbee network, a gateway of the Zigbee network represents end devices in communications with peripheral networks. The gateway receives messages, such as status request messages, from the peripheral network intended for an end device on the Zigbee network. The Zigbee network generates a response message by retrieving stored data for the end device instead of communicating the received message to the end device.

  • Patent number: 9730150
    Abstract: A mobile device performs a scanning operation for identifying a wireless network and receives from the wireless network a hotspot aggregator service identifier which identifies a hotspot aggregator service made available via the wireless network. The mobile device compares the received hotspot aggregator service identifier with one or more hotspot aggregator service identifiers stored in memory. When there is a match between the received and the stored hotspot aggregator service identifiers, the mobile device initiates a connection with the wireless network for receiving the hotspot aggregator service.

  • Patent number: 9661616
    Abstract: The present invention relates to reporting the channel state information in a communication system. The channel state information is reported from the user terminal to a base station. Accordingly, the user terminal determines a first channel state information value from a first set of values (levels) and a second channel state information value from another set of values, preferably a larger set of values. Then a difference or other relative measure is calculated between the first and the second channel state information value and transmitted to the base station.
