20080200198 | METHOD AND APPARATUS FOR REGISTRATION OF LOCATION INFORMATION OF WIRELESS DEVICES IN A WIRELESS COMMUNICATION NETWORK SUPPORTING MULTICAST CALLS - An apparatus and method for transmitting push-to-talk (PTT) communications through multicast channels to a plurality of wireless devices. The PTT server uses the unicast approach to deliver the PTT communication to a group of PTT clients when it does not have the location information of the PTT clients in the group. In one embodiment, the wireless devices report their location to a PTT server after receiving a PTT communication for a group and a timer is started. The wireless devices continue to report their location when moving from an area served by one base station to an area served by another before the timer expires. The PTT server also starts the timer for that PTT group with the same value after initiating the PTT group communication. The PTT server uses the location information to determine if multicast channels can be used when transmitting PTT communications to the wireless devices. | 08-21-2008 |

20160381143 | Controlling an IoT Device Using a Remote Control Device via an Infrastructure Device - Described herein are implementations for using a remote control device to control a target device on a network. An exemplary remote control device may generate a data packet comprising a command for controlling the target device and a network address associated with the target device. The remote control device may establish a connection to an infrastructure device on the network, and transmit the data packet to the infrastructure device. The infrastructure device may multicast the data packet to a plurality of IoT devices on the network. An IoT device, of the plurality of IoT devices, may execute the command based on determining, using the network address, that the IoT device is the target device. | 12-29-2016 |
