Abstract
An IPTV group profile is dynamically generated based on individual IPTV user profiles, whenever a user joins or leaves a shared IPTV session at an IPTV Terminal Function (ITF). The IPTV group profile may be implemented as a modification to the IPTV user profile of each user. In one embodiment, a “group” branch includes the additional access privileges and/or restrictions from the IPTV user profiles of other group members. The modified IPTV user profiles of users in the group are placed on a network entity such as an XDM Server (XDMS), to which the ITF subscribes via XCAP. As users join or leave a shared IPTV session at an ITF, the IPTV-AS updates the IPTV user profiles on the XDMS, which notifies the ITF of the changes. Each user's IPTV user profile at the ITF thus reflects group access privileges, preferences and restrictions for the duration of the shared IPTV session.
