A system for determining the skill of a player eliminates the element of chance by comparing players who have the same initial position. In the case of cards, the initial position is the hand dealt to the player and in tile games, it is the initial distribution and arrangement of tiles. A player with a less than advantageous initial position may win a game over an opponent having a better initial position. It cannot conclusively be said whether this win is due to the good play of the winner or the bad play of the loser. However, it can clearly be said that the winning player has a higher skill level than the losing player.

The invention relates to a method for distributing control signaling for session control of a multicast or broadcast service within a mobile communication network. Furthermore the invention also provides a base station, mobile terminal and communication system to perform the proposed method. In order to reduce the number of signaling connections for the service, the invention proposes to avoid the initial distribution of session control signaling in the entire mobile communications network or service area. Rather than providing service related control signaling connections upon session start, the control signaling connections are set up in response to service requests of the mobile terminals requesting the service. According to one further aspect, the mobile terminals send the service requests based on service announcements available at the mobile terminals, i.e. in contrast to conventional implementations, the mobile terminals do not await a notification of the access network on the availability of the service within the cell.

A controlled content distribution system (CCDS) employs a peer-level application into which a content producer can import digital content (e.g., video, audio, graphic, image, text, code files, etc.) The content producer identifies distribution parameters including an initial distribution list and a level limit representing the maximum number of levels, or degrees of separation for allowed distribution in a FOAF social network. Distribution parameters also include an alteration definition for one or more allowable levels in the network. Alteration definitions may identify a file degradation characteristic, file augmentation, or deletion parameter for altering the digital content from its original form. Alteration definitions often vary at each level. A distribution package is created by the CCDS and includes the digital content, a configuration data file, a key ID and a license key seed. The distribution package is processed at a FOAF license server before being sent to additional content recipients.
