Abstract:
1. A method comprising: causing at least in part, intercepting, by an intermediary service element, a signaling message sent by a terminal to a network entity to establish a data communications session using a session establishment protocol; identifying, via a profile database associated with the session establishment protocol, personal characteristic associated with user of the terminal, wherein the personal characteristic describes an intrinsic attribute of the user; obtaining, via a policy database that stores a group access policy relating to the establishment of communications sessions with the network entity, a predetermined criterion for allowing establishment of the data communications session based on the personal characteristic satisfying the group access policy; causing, at least in part, embedding, via the intermediary service element, a token in the signaling message, the token representing at least one of the personal characteristic and the predetermined criterion; causing, at least in part, communicating the signaling message via a network service element capable of allowing the user to establish the data communications session, wherein the network service element establishes the data communications session if the personal characteristic satisfies the predetermined criterion.
