Abstract: A method and a scoring node for estimating a user's Quality of Experience, QoE, when a service is delivered in a media stream to the user by means of a communication network. Quality-related parameters pertaining to the service delivery are extracted, and an individual opinion score is determined for each of a set of quality models by applying each respective quality model in the set on the quality-related parameters. An aggregated opinion score is then determined as a weighted average of the individual opinion scores. The aggregated opinion score can then be used as an estimation of the user's QoE for the service delivery, e.g. when evaluating the service and/or the communication network.

Abstract: Network services exchange data packets with mobile terminals wirelessly connected to a network. The network receives reports from a subset of the mobile terminals. The reports indicate network services used by the reporting mobile terminals. Various corresponding methods include the network associating one or more first data packets with one of the network services based on the reports. The first data packets originate from, or are addressed to, the reporting mobile terminals. The network derives or adapts, based on data included in the first data packets, one or more rules for identifying the network service based on data included in second data packets. The second data packets are different from the first data packets.

Abstract: The invention relates to a method for performance reporting in a wireless network, wherein at least one terminal is associated to a terminal report server by means of information in the terminal. Prior to initiating the performance report, information on operator identity is retrieved. The operator identity is combined with information identifying the associated terminal report server to compile a fully qualified domain name. Connectivity information to the terminal server report is requested and received from a domain name server, whereupon a performance report session to the terminal report server is initiated using the received connectivity information. The invention also relates to a terminal wherein the inventive method is applied.
