Presence Management and Merging Presence Information for NGN Services

摘要

This paper describes an approach for interworking scenarios between Session Initiation Protocol (SIP) based and non SIP based frameworks (e.g. web services) in case of the presence management service. The characteristics of the concept of a centralized presence management will be introduced.rnBased on the Parlay X web service framework a presence management service solution has been developed, deployed and tested. The re-usability of the developed presence management service solution within an IP Television (IPTV) framework and the future potential of the presence service in various IPTV applications are analyzed.
