Abstract: The present invention relates to a first and second method and corresponding nodes for generating dynamic Service Point Triggers, SPTs, in an IP multimedia subsystem, IMS. The first method comprises receiving, at a first node, Initial Filter Criteria, IFC, belonging to a service profile of a user subscribed to said IMS, said IFC including a plurality of preset SPTs, respectively indicating conditions to be evaluated and information including at least one criterion for generating one or more dynamic SPTs; evaluating, at said first node, said plurality of preset SPTs according to a configured order of priorities; generating, at said first node, if said at least one criterion is met, one or more dynamic SPTs based on said information, whereby said dynamic SPTs indicate respective new conditions to be evaluated. The second method comprises configuring, at a second node, the above IFC, and providing the configured IFC to the above first node during initial registration of the user.
