Abstract: An IP telephony system allows users of the IP telephony system to register extension telephony devices with the IP telephony system. An extension telephony device is one that is provided with service by a separate telephony service provider. Once an extension telephony device is registered, a user can obtain communications services from the IP telephony system using the extension telephony device. A extension telephony device may be tied to a user's main telephony services account with the IP telephony system such that when the user obtains communications services from the IP telephony system using an extension telephony device, the user will be billed for those communications services through the user's main account.

Abstract: The present application provides a network delay control method and apparatus, an electronic device, and a storage medium. A current end-to-end network delay type is determined, then a proper strategy is adopted according to the determination result. For example, when the determination result is the network inherent delay, the sending speed of the sending end can be kept or increased, the sending speed of the sending end is prevented from being reduced, and the network transmission efficiency is ensured. When the determination result is the network congestion delay, the sending speed of the sending end can be reduced, and the delay is reduced.

Abstract: The present disclosure describes techniques and systems for user device-initiated bandwidth requests. In some aspects, a user device determines conditions related to communicating with a base station over a wireless connection. The user device selects, based on the determined conditions, a frequency bandwidth for communicating with the base station. The user device then transmits, to the base station, a request to communicate over the selected frequency bandwidth. In some implementations, the user device may receive, in response to transmitting the request, a resource grant allocating at least a portion of the selected frequency bandwidth for communicating over the wireless connection.

Abstract: An apparatus, system, method, and computer-readable recording medium transfer a media session from a companion device to a media hub device connected in a network. A swipe operation is performed on the companion device, and a scan request is transmitted from the companion device to media hub devices connected in the network. The companion device receives a response packet from each media hub device based on the scan request. Each response packet includes a media access control (MAC) address. The companion device calculates a received signal strength indicator (RSSI) indicating signal strengths of the media hub devices based on each response packet, and determines a media hub device having a strongest signal strength. A media session executing on the companion device is then transferred over IP to the media hub device having the strongest signal strength.

Abstract: Systems, methods, and instrumentalities are disclosed to describe cell selection in low cost machine type communication (LC-MTC) devices. An LTC-MC device may measure a plurality of downlink signals from a plurality of cells. The LTC-MC may detect a channel condition, e.g., by determining a cell with better uplink coverage than a downlink cell. The detection of the channel condition may include measuring an uplink pathloss. The LTC-MC may report the channel condition as a decoupled channel condition, e.g., when an uplink cell is identified with uplink coverage better than the downlink cell. The channel condition may be reported, e.g., via a set of Physical Random Access Channel (PRACH) preambles. The set of PRACH preambles may be predefined. The channel condition may be reported via a higher layer signaling.
