20140043994 | Providing Feedback To Media Senders Over Real Time Transport Protocol (RTP) - The principal object of this embodiment is to provide regular feedback about the packet losses from a receiver to a sender in a RTP based network, based on which the sender then decides to control its transmission rate resulting in better quality of experience (QoE) for the receiver. Another object of the embodiment is to propose a method and system to send and receive feedback using lightweight protocol packets on a periodic or on as-per-required basis in a RTP based network. A further object of the embodiment is to propose a method and system to calculate and forecast Round Trip Times (RTT) at a RTP receiver in a RTP based network using double exponential smoothing methodology to calculate packet losses in that RTT. | 2014-02-13 |
20140043995 | BASE STATION, COMMUNICATION TERMINAL AND METHOD FOR TRIGGERING INTERFERENCE AVOIDANCE MESSAGE FOR COMMUNICATION TERMINAL - A base station, a communication terminal and a method for triggering an interference avoidance message for a communication terminal. The communication terminal includes a Long Term Evolution (LTE) module and a communication module coexisted with the LTE module. The method includes: a measurement process for measuring a signal quality parameter and a traffic flow parameter; a traffic flow judgment process for judging whether the traffic flow parameter satisfies a predetermined condition; a signal quality judgment process for judging whether the signal quality parameter satisfies a predetermined condition; a triggering determination process for determining whether a trigging condition is satisfied according to a judgment result of the traffic flow judgment process and a judgment result of the signal quality judgment process; and transmitting the interference avoidance message when the triggering determination process determines that the trigging condition is satisfied. | 2014-02-13 |
