20100150171 | Controlling packet transmission - The invention provides a method of controlling transmission of packets from a transmitter to a receiver via a channel, and a corresponding transmitter and receiver. The method comprises: transmitting packets from a queue, each packet having a packet size based on data in the packet; determining a transmission time for each packet, based on a transmission clock; determining a reception time of each packet, based on a reception clock; supplying to an estimation function successive sets of observations including in each set transmission time, reception time and packet size, the estimate function being arranged to provide an estimate of bandwidth for the channel using the relationship between the bandwidth, the amount of data in the queue, packet size and the delay between transmitting successive packets from the queue; and using the estimated bandwidth to control transmission of packets. | 06-17-2010 |
20110141925 | Measuring call quality - Provided is a method, computer program product, and apparatus for estimating the quality of a call in which a first user terminal will comprise an end point. The method comprises establishing an end-to-end connection between a first user terminal and a node, which end-to-end connection is via an access point of a network by which the first user terminal is connected to the network; displaying information indicative of an expected quality of a call in which the first user terminal will comprise an end point, in dependence on information indicative of the quality of the end-to-end connection; and providing call initiation means for enabling a user to then selectively establish a call between the first user terminal and a callee. Also provided is a method, computer program product, and apparatus for estimating the quality of a call between a first user terminal and a potential callee. | 06-16-2011 |
20130329751 | REAL-TIME COMMUNICATION - Receiver, computer program product and method for processing data of a real-time communication event. A processing module of the receiver implements a real-time communication application to receive a data stream of the real-time communication event. Data of the received data stream is output to a user in the real-time communication event. Interaction of the user with the real-time communication application during the real-time communication event is determined, and the data rate of the received data stream in the real-time communication event is controlled based on the determined interaction. | 12-12-2013 |

20140273990 | Observation Assisted Bandwidth Management - Observation assisted bandwidth management techniques are described. In one or more implementations, a request is received at a terminal to initiate a call with another terminal. Responsive to the request, a communication is formed to be communicated to a service provider for bandwidth parameters, the request including network parameters associated with the terminal. The bandwidth parameters, received form the service provider, are used as part of a model to estimate an amount of bandwidth that is available for the call. The call with the other terminal is initiated, the call configured to at least initially consume the estimated amount of bandwidth. | 09-18-2014 |
20140372623 | RATE CONTROL - There is provided a method of controlling a rate at which content data is received at a receiver over a network, wherein the receiver has caused a first stream of real-time communication event data to be received at the receiver, and a second stream of content data to be received at the receiver, the method comprising steps of: dynamically measuring network conditions of the network based on the real-time communication event data; and limiting the rate at which the content data is received at the receiver based on the dynamically measured network conditions. | 12-18-2014 |
20150046927 | Allocating Processor Resources - Disclosed herein is a method of allocating resources of a processor executing a first real-time code component for processing a first sequence of data portions and a second code component for processing a second sequence of data portions. At least the second code component has a configurable complexity. The method comprises estimating a first real-time performance metric for the first code component, and configuring the complexity of the second code component based on the estimated first real-time performance metric. | 02-12-2015 |
20150055465 | Controlling Transmission of Data - In an embodiment, a method of controlling transmission of data from a wireless device to a receiver connected via a communication channel includes an application executing on the wireless device providing an estimate of end-to-end bandwidth of the communication channel; supplying to the application from wireless access circuitry in the wireless device at least on communication-related parameter and modifying in the application the estimate of end-to-end bandwidth using the at least one communication-related parameter. | 02-26-2015 |
