Abstract: A method for providing communication services as VASs to subscribers of a communication service provider based on building a subscriber relationship data structure in a data store. The method includes building the subscriber relationship data structure such that it comprises a first layer which comprises a first VAS node corresponding to a first VAS and a second layer comprising one or more service group nodes and corresponding service groups. The method additionally includes receiving a first request from a first subscriber and from a second. The method further includes modifying the subscriber relationship data structure such that the one or more service group nodes comprises a first service group node in which the first subscriber and the second subscriber are each identified as belonging to a corresponding first service group of the one or more service groups, and deploying the first VAS to the first and second subscribers.
