AUTHENTIFICATION AND/OR BILLING MEDIATION SERVICE APPARATUS AND METHOD

摘要

A mobile unit (14) that seeks to make use of near-real-time multicast communication services via a corresponding services server (13) can effect at least a measure of authentication with a session initiation protocol infrastructure via a RADIUS server (12) through intermediation of a mediation server (10). In addition, or in lieu thereof, billing for such services can be facilitated through the mediation server (10).
