Abstract: A device retrieves a first subset of events from data associated with a network, and determines one or more discriminating features of the first subset of events using a feature selection method. The device also retrieves one or more additional subsets o f events, different than the first subset of events, from the data associated with the network, and cross validates the one or more discriminating features based on the one or more additional subsets of events. The device further detects a feature that is a root cause of a problem in the network based on the cross validated one or more discriminating features.

Abstract: A method and apparatus for providing an Interactive Television service. T he method comprises storing user preferences relating to the service and, at one of a Personal Interaction Profile function and a Group Interaction Prof ile function, receiving from a broadcast server information identifying an e vent relating to the interactive service. The received information is compar ed with the user preferences to determine whether a notification should be s ent to the user and, if it is determined that the notification should 10 be sent to the user, the notification is sent to a user device.

Abstract: A method of estimating a default rating of a rated dataset is provided, where the dataset comprises at least one series of ratings associated with at least one user and each series comprise ratings associated with at least two items. For a reference user and an item for which a rated value is missing the item' s average rating, i

Abstract: Un metodo y disposicion para establecer una sesion multimedia de paquete intercambiado para una terminal movil (A) en comunicacion con otra parte (B), en donde un contexto de PDP (Protocolo de Paquete de Datos) primario se ha activado en una red movil para la terminal movil. Se recibe la informacion en la sesion entrante (paso 5:3) que se ha negociado y acordado entre las partes en comunicacion. Por lo tanto se determina (paso 5:4) si algun recurso de red que provee QoS requerido se requiere para la sesion y si se va a activar un contexto de PDP secundario para la terminal movil y la sesion entrante. Si se requieren los recursos de red y se va a activar un contexto de PDP secundario, se acciona la activacion de dicho contexto de PDP secundario (paso 5:5).

Abstract: A method of estimating a default rating of a rated dataset is provided, where the dataset comprises at least one series of ratings associated with at least one user and each series comprise ratings associated with at least two items. For a reference user and an item for which a rated value is missing the item' s average rating, ir, the reference users average rating, R u , and the datasets average rating, dr, is collected. A Poisson distribution of the reference users rating is then generated on the basis of the reference users average rating. A random Poisson rating, ur, is calculated on the basis of the Poisson distribution, and a default rating, r, is estimated by weighting the random Poisson rating on the basis of the items average rating, the users average rating and the datasets average rating.

Abstract: A method and apparatus for performing a caller investigation in order to provide relation information to a called party (200) regarding an unknown ca lling party (202), when implemented in a service entity (204) serving said c alled party. A relation query for the calling party is received from the cal led party, and it is then determined whether the calling party is known and related to any third party directly or indirectly known to the called party by checking a contact list (210-214) defined for said third party. The relia bility of the calling party can then be better assessed based on how the cal ling party is related to the called party, if related at all. The called par ty may use this information for deciding how to respond to a communication r equest from said calling party.
