Dynamic MBMS Control for Service-Specific UE Grouping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current MBMS systems lack the ability to dynamically adjust broadcast/multicast transmission areas based on user equipment (UE) service requirements, leading to inefficient resource allocation and increased power consumption due to static control configurations.
Innovation Solution
A method for dynamic MBMS control that involves UEs sending indication messages with service requirements, allowing network nodes to group UEs based on service types and QoS, and transmitting optimized control configurations to each group, including MCCH and MBMS scheduling adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If static control configurations are used in MBMS systems, then system simplicity is maintained, but resource allocation efficiency deteriorates and power consumption increases
Solution Approach 1:
The patent implements dynamic control configurations that adapt to changing service requirements and UE distributions. The network node dynamically adjusts MBMS control parameters based on received indication messages from UEs, transforming the static system into a dynamic one that optimizes resource allocation while maintaining manageable complexity through automated adaptation.
Solution Approach 2:
The patent changes control configuration parameters based on service requirements and UE feedback. By modifying parameters such as scheduling intervals, transmission power, and resource allocation patterns according to actual network conditions, the system improves resource efficiency without requiring complete reconfiguration, thus balancing complexity and performance.
2Use of energy by moving object
If static control configurations are used in MBMS systems, then configuration management is simplified, but power consumption increases due to inefficient resource allocation
Solution Approach 1:
The patent adjusts control configuration parameters dynamically based on service requirements and UE distribution patterns. By optimizing parameters such as scheduling intervals and transmission resources according to actual conditions, the system reduces unnecessary power consumption while maintaining simplified configuration management through automated parameter adaptation.
3Productivity
If dynamic MBMS control is implemented, then resource allocation efficiency improves, but system complexity increases
Solution Approach 1:
The patent implements dynamic control where the network node continuously adapts MBMS configurations based on UE feedback and service requirements. This dynamic approach improves resource allocation efficiency by matching control parameters to actual network conditions while managing complexity through automated adaptation mechanisms rather than manual configuration.
Solution Approach 2:
The patent introduces feedback loops where UEs send indication messages about their service requirements and network conditions. The network node uses this feedback to dynamically adjust control configurations, creating a closed-loop system that improves resource efficiency while managing complexity through information-driven automatic adaptation.
4Reliability
If service-specific control configurations are transmitted to different UE groups, then service quality improves, but signaling overhead increases
Solution Approach 1:
The patent segments UEs into different groups based on their service requirements and transmits tailored control configurations to each group. This segmentation improves service quality by providing optimized configurations for specific service types while managing signaling overhead through group-based rather than individual configuration transmission.
Solution Approach 2:
The patent applies different control configuration qualities to different UE groups based on their specific service requirements. Each group receives control parameters optimized for its particular service needs, improving overall service quality while reducing signaling overhead compared to transmitting individualized configurations to every UE.

AI summary
A method for dynamic MBMS control is proposed for a network node in a MBSFN service area to provide MBMS services to one or more UEs. A telecommunication system and a UE implementing the method are also proposed. A plurality of indication messages are received from one or more UE. Each of the indication messages comprises an indication about the service type and/or the QoS information for one or more MBMS services. At least one control configuration is determined based on to the required one or more MBMS services. The at least one control configuration are transmitted to the UEs, so that the UEs are configured to efficiently receive the required service.
