Abstract:
In an embodiment, a first MBSFN area is configured to support a higher data rate than a lower data rate portion of a second MBSFN area, and an application server executes a common data rate mode by delivering a data stream for a group session to the first and second MBSFN areas via IP multicast at a common data rate that is regulated by quality feedback. In a further embodiment, the application server exits the common data rate mode and delivers the data stream to the first MBSFN area via IP multicast at an MBSFN-specific data rate that is higher than the common data rate, while delivering the data stream to the lower data rate portion of the second MBSFN area via IP unicast. In another further embodiment, the application server resumes the common data rate mode.
