Device, computer program and method for providing video content and data to a user device (). The method includes providing the video content to the user device (), sending a first message from a network operator system () to the user device (), the first message including at least one of an instruction for downloading the data or a table () storing information about the data, wherein each of the instruction and the information about the data informs the user device () to search a peer-to-peer network () for the data, and receiving at the network operator system () a second message from the user device () indicating that the data has been downloaded from the peer-to-peer network ().

Personalized data distribution based on peer-to-peer content delivery

The present invention comprises a content delivery system for delivering content to clients. The content delivery system comprises at least one mobile object adapted to be executed on the content delivery system and on other content delivery systems or multimedia devices adapted for mobile objects. Each mobile object comprises a media file and is further adapted to determine the capabilities of the other content delivery systems or multimedia devices and to monitor data related to the clients' access of the media file. The content delivery system also comprises a transcoder unit for transcoding the media file to another media file prior sending it to the other content delivery system or multimedia device. The invention solves problems that can arise when sending large media files to content delivery systems or multimedia devices having limited capabilities.

Method for content delivery involving a policy database

An improved method and system of measuring the perceived speech quality in mobile telecommunications networks is disclosed herein. In an embodiment of the invention, the method uses both radio link parameters and an objective measuring technique performed on received signals to estimate the speech quality perceived by the end-user. A radio link processing stage extracts temporal information from a set of available radio link parameters such as the BER, FER, RxLev, handover statistics, soft information, and speech energy. Concurrently, a speech processing stage is used to process a sequence of original signals and received signals, obtained from the output of a telecommunications system. The signal sequences are processed by an objective measuring technique such as Perceptual Speech Quality Measure (PSQM). The outputs from the radio link processing and speech processing stages are utilized to calculate an estimate for speech quality. Furthermore, a weight may be given to radio link processing and speech processing in accordance with their performance under various conditions such that the overall speech quality is calculated with respect to the best approach.

Speech quality measurement based on radio link parameters and objective measurement of received speech signals

A method and system for measuring the speech quality in a mobile cellular telecommunications network using available radio link parameters is disclosed herein. In a preferred embodiment, the method includes receiving a set of radio link parameters, as defined in a standard or otherwise available, such as the BER, FER, RxLev, handover statistics, soft information, and speech energy. Temporal information is obtained from the radio link parameters to create a set of temporal parameters which can be statistically analyzed, for example, for the maximum and minimum, mean, standard deviation, and autocorrelation values for a time interval. The temporal parameters are combined to yield a set of correlated parameters that are more closely related to the speech quality. An estimator then uses the correlated parameters to calculate an estimate for the speech quality. The method of the present invention takes advantage of temporal information and correlated relationships from the transmitted parameters. Furthermore, the method is inherently simple and reliable as compared to prior art methods. Still further, the technique provides a method that allows operators to monitor quality conditions throughout the network.
