dc.description.abstract	Presence information contains all the context about users, services and devices that applications need to take more proactive and intelligent decisions. SIP/SIMPLE is the de facto framework for initiating, managing and personalizing presencebased communications in the Next-Generation Networks. However, SIMPLE subscription model generates a traffic overload that is restraining mobile operators from implementing advanced presence-based applications. RLS is a widely-adopted optimization of SIMPLE subscription traffic in mobile applications. We analytically measure the presence traffic on the access link between an end-user and the network with and without an RLS. We present the parameters that affect the RLS’ performance and give some guidelines when considering whether or not to use an RLS.
