Presence service providing method for e.g. public radiotelephone network, involves querying databases to provide information constituting characteristics of presence context of calling user for determining characteristics of context

摘要

The method involves querying a set of network or service users management databases (DB1-DB4), from a presence server (PS), for determining the databases which manage subscriptions to a calling user (U1). The databases are requested to provide information that constitutes characteristics of presence context of the user for determining the characteristics of the context. Communication towards a user to be called (U2) is established by receiving information that constitutes characteristics of presence context of the user to be called and selecting the characteristics of communication.
