The IP Multimedia Subsystem (IMS) is a standardised Next Generation Network (NGN) architectural framework defined by the 3rd Generation Partnership Project (3GPP) to bridge the gap between circuit\u2010switched and packet\u2010switched networks and consolidate both sides into on single all\u2010IP network for all services. In this paper, we provide an insight into the limitation of the presence service, one of the fundamental building blocks of the IMS. Our prototype\u2010based study is unique of its kind and helps identifying the factors which limit the scalability of the current version of the presence service (3GPP TS 23.141 version 7.2.0 Release 7 [1]), which will in turn dramatically limit the performance of advanced IMS services. We argue that the client\u2010server paradigm behind the current IMS architecture does not suite the requirements of the IMS system, which defies the very purpose of its introduction. We finally elaborate on possible avenues for addressing this problem.<\/jats:p>","DOI":"10.1155\/2007\/758738","type":"journal-article","created":{"date-parts":[[2015,1,12]],"date-time":"2015-01-12T13:57:19Z","timestamp":1421071039000},"page":"187-202","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Presence in the IP Multimedia Subsystem"],"prefix":"10.1155","volume":"3","author":[{"given":"Ling","family":"Lin","sequence":"first","affiliation":[]},{"given":"Antonio","family":"Liotta","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2007,10,15]]},"container-title":["Mobile Information Systems"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2007\/758738.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/2007\/758738","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,8,7]],"date-time":"2024-08-07T23:34:12Z","timestamp":1723073652000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1155\/2007\/758738"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007,1]]},"references-count":0,"journal-issue":{"issue":"3-4","published-print":{"date-parts":[[2007,1]]}},"alternative-id":["10.1155\/2007\/758738"],"URL":"https:\/\/doi.org\/10.1155\/2007\/758738","archive":["Portico"],"relation":{},"ISSN":["1574-017X","1875-905X"],"issn-type":[{"type":"print","value":"1574-017X"},{"type":"electronic","value":"1875-905X"}],"subject":[],"published":{"date-parts":[[2007,1]]},"assertion":[{"value":"2007-10-15","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2007-10-15","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2007-10-15","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
