Multicast Transport Channel Allocation for MBMS Throughput

The patent implements dynamic allocation of multicast transport channels by evaluating current buffer status and data rate requirements in real-time. The system transitions from static or historic-based scheduling to a dynamic approach where channels are allocated based on current network conditions, buffer occupancy, and service requirements, thereby optimizing throughput while managing complexity through structured decision-making

The system incorporates feedback mechanisms by continuously monitoring buffer status, data rate requirements, and channel allocation outcomes. This feedback loop enables the scheduler to adjust allocations in subsequent common sub-frame allocation periods, preventing both underload (wasted capacity) and overload (dropped services) scenarios while maintaining optimized throughput

The patent dynamically adjusts allocation parameters including the number of multicast transport channels, their data rates, and timing characteristics based on current buffer status and service demands. By changing these parameters adaptively rather than fixing them, the system can accommodate growing service capacity requirements while minimizing unused physical data rate through precise matching of channel characteristics to actual needs

The system allocates multicast transport channels in a controlled manner, sometimes allocating fewer channels than maximum capacity allows (partial action) to avoid overload, and other times utilizing available buffer space efficiently when capacity exists (excessive action to prevent underutilization). This balanced approach prevents both wasted capacity and dropped services
