Increasingly, multimedia services require efficient delivery systems to support content distribution. If a service targets groups of users then a point-to-multipoint distribution technology is naturally more optimized. 3GPP has specified MBMS (Multimedia Broadcast Multicast Service) and E-MBMS (Evolved MBMS) systems to broadcast and multicast rich media contents to mobile communities in an efficient way. But these systems can be enhanced with a permanent access to users' context information for dynamic group management leading to effective content distribution. This paper proposes an algorithm that employs the ubiquitous awareness of the user situation to optimize the multimedia content distribution to user groups, saving the resources of the mobile operators' networks.
