Embodiment Construction

[0028] The present invention relates to applications running on application servers (such as SIP application servers) or general web servers. Examples of this are multiparty / interactive games, or generally multiparty applications that require one user (friend) to interact temporarily with other users. The invention can be applied when buddies change over time, so that a user manages multiple "dynamic" contact lists (Dynamic Buddy Lists, DBL).

[0029] By using the present invention, a tool capable of managing a dynamic virtual community is provided for applications in consideration of user privacy. Each virtual community can be regarded as a group from which several buddy lists (BL) are derived. Administration includes creating, modifying and deleting lists, and last but not least, automatically distributing lists to members when required by the application. Every member of such a virtual community will see the other members on a dedicated BL. Community membership (and thus...

Abstract

There are provided a method of and an apparatus for server-side management of contact lists in a presence enabled application supported by a communication system and having a client side (CA) on a user equipment (UE) and a server side (AS) within a presence enabled network (PEN) accessible by the users through said communication system, the application being of a type in which users of the application form time-variable virtual communities of users that temporarily interact for the purposes of the application. The method includes: users' registration with the server-side of the application (AS), to provide candidates for said virtual communities; creation, from the candidates, of a list of the members of each virtual community ("buddy list") in a buddy list management unit (DBLM) in said presence enabled network (PEN); notification of the buddy list by the list management unit (DBLM) to client units (DBLC) in the user equipment (UE) of members of the community; and displaying the notified list on the user equipment (UE) of each member receiving it.
