Patent

CA 2535858

A method and apparatus for time-based charging for viewing content from a broadcast-multicast service (BCMCS) at a mobile station of a wireless communication system is disclosed. A count value (SKCount) is determined based upon the number of generated short-term keys (SK) that are used to decrypt particular content from the BCMCS. The amount of time the particular content is viewed at the mobile station may be determined as a function of the count value (SKCount) and the period (SKPeriod) between the generation of the short- term keys. This provides information about a user's actual content view time since the short-term key is needed to view the particular content broadcast to the mobile station.

La présente invention a trait à un procédé et appareil pour la facturation temporelle pour le visionnement de contenu en provenance d'un service de diffusion multi-destination au niveau d'une station mobile d'un système de communication sans fil. Une valeur de comptage (SKCount) est déterminée en fonction du nombre de clés à courte terme générées (SK) qui sont utilisées pour le déchiffrement d'un contenu particulier en provenance du service de diffusion multi-destination. La quantité de temps durant lequel le contenu particulier est visionné au niveau de la station mobile peut être déterminée en fonction de la valeur de comptage (SKCount) et la période (SKPeriod) entre la génération de clés à court terme. Cela fournit une information concernant le temps de visionnement réel de l'utilisateur étant donné que la clé à court terme est requise pour le visionnement de la diffusion du contenu particulier à la station mobile.
