Method and Arrangement For Ranking Users

A ranking manager apparatus configured to provide information on a social rank of a first terminal user within a plurality of terminal users in a telecommunication network, comprising:

• a data receiver adapted to receive collected transaction data referring to communication events involving said users,
• a data analyzer adapted to identify a cluster of socially related users, including the first user, from said plurality of users based on the collected transaction data, wherein any two users in the cluster are deemed to be socially related when exceeding a predefined minimum communication event threshold, and further adapted to determine relation metrics for the users in the cluster based on the collected transaction data, said relation metrics indicating an extent of aggregated outgoing communication events between the users in the cluster, and
• a ranking calculator adapted to calculate the social rank of the first user in multiple successive iterations by calculating the social rank of the first user in each iteration based on relation metrics of aggregated outgoing communication events from the first user, and further based on social ranks calculated in a preceding iteration for other users in the cluster being subjected to said outgoing communication events, until the social rank of the first user is deemed to be stabilized, and further adapted to provide the calculated social rank of the first user to one or more service providers.
