MBMS Scheduling Sequence Ordering for Base Station Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing MBMS systems lack a mechanism for dynamic scheduling of service data synchronization across base stations in MBSFN areas, leading to difficulties in ensuring synchronization multiplexing transmission and scheduling of MSCH.
Innovation Solution
The base station equipment obtains a scheduling sequence for MBMS, orders the received synchronization data frames accordingly, and sends them to ensure synchronization scheduling and multiplexing between base stations, thereby achieving statistical multiplexing gain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If base stations receive synchronization data frames from core network without ordering mechanism, then reception is simple, but synchronization scheduling and multiplexing cannot be ensured
Solution Approach 1:
The patent applies preliminary action by introducing a scheduling sequence that is determined and prepared in advance before the actual data frame transmission. The base station receives the scheduling sequence from the core network and uses it to order synchronization data frames before transmission, ensuring proper synchronization scheduling without complex real-time processing during transmission.
2Productivity
If multiple MBMS are mapped on same MCH without dynamic scheduling, then system is simpler, but statistical multiplexing gain cannot be obtained
Solution Approach 1:
The patent applies dynamics by introducing dynamic scheduling mechanisms that allow the system to adaptively allocate resources to multiple MBMS services mapped on the same MCH. The scheduling sequence and resource allocation are dynamically adjusted based on service requirements, enabling statistical multiplexing gain while maintaining system flexibility.
3Reliability
If base stations transmit synchronization data frames simultaneously without ordering, then transmission is simpler, but service data synchronization cannot be ensured
Solution Approach 1:
The patent applies preliminary action by determining the scheduling sequence in advance based on the scheduling information received from the core network. This pre-determined sequence allows base stations to order synchronization data frames correctly before transmission, ensuring service data synchronization without requiring complex real-time coordination during transmission.
