Abstract
A method and arrangement for providing information to a client from a client access network regarding a requested set of users, at least some of which are connected to other access networks. In response to a client subscription request, the client access network establishes a network subscription with the other access networks. Information updates regarding users in the set are then continuously received and stored in a database of the client access network, whenever the users change their state. In response to a subsequent request for user information from the client, corresponding stored user information is retrieved from the database and sent in a notification to the client.
