Abstract: The disclosure relates to a communication client application for running on a user terminal to conduct calls over a network. The client is configured to access a model which models quality of user experience for calls based on a set of technical parameters of each call. The model itself is based on user feedback indicating subjective quality of multiple past calls as experienced by multiple users, modeled with respect to the technical parameters collected from each of the past calls. The model generates a predicted call quality score predicting the quality of user experience for the call given its technical parameters. Based on this process, one or more of the technical parameters of the call can be adapted to try to increase the quality experienced by the user.

Abstract: Method, system, device, server and computer program product for analyzing a communication event occurring over a network, wherein a network service provider provides access to the network for a communication client executed at the device to engage in the communication event. The communication client detects a problem with the communication event. Communication metric data relating to the communication event is determined. It is determined, using the determined communication metric data, whether the detected problem is caused by a reason (i) of a poor network condition in the network, or a reason (ii) of the network service provider discriminating against transmission over the network of a type of data used in the communication event. In the event that it is determined that the detected problem is caused by reason (ii), a notification is provided to a user of the device.

Abstract: Method, user terminal and computer program product for processing data relating to a communication event at a communication client, the communication event occurring over a communication system. An input of the communication event is received at the communication client from a user of the communication system. The input is analyzed to determine attributes of the input. At least one other user of the communication system who is likely to be a participant of the communication event is determined based on the occurrence of attributes, corresponding to the determined attributes of the input, in previous communication events over the communication system involving at least one of the at least one other user. The communication client indicates, to the user, the determined at least one other user as being a likely participant for the communication event.
