A Multicast Mechanism for Mobile Multimedia Messaging Service
Source: National Taiwan University
Based on the cell broadcast service architecture, this paper proposes an efficient multicast mechanism for the universal mobile telecommunications system to support Multimedia Messaging Service (MMS). The authors define a new interface between the serving GPRS support node and the cell broadcast center to track the current locations of the multicast members. Then one describe the location tracking procedures (including attach, detach, and location update) of the multicast members and the multicast message delivery procedure. One uses an analytic model to investigate the performance of the approach. This paper indicates that the MMS multicast mechanism outperforms the previous proposed approaches.
