Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current MBMS systems lack an effective mechanism to control the activation and deactivation of MBMS services based on uplink feedback from UE, leading to inefficient resource allocation and utilization.
Innovation Solution
A method and system that process uplink feedback information from UE to make activation/deactivation determinations, involving statistical gathering and threshold-based decisions by eNBs and MCEs, with OAM software or manual intervention to optimize MBMS service transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If MBMS services are continuously transmitted without activation/deactivation control, then service availability is maintained, but network resources are wasted due to lack of user interest
Solution Approach 1:
The patent implements dynamic activation and deactivation of MBMS services based on real-time uplink feedback from UEs. The MCE receives feedback information indicating user interest in specific services and dynamically adjusts service transmission state accordingly, transitioning from static continuous transmission to dynamic on-demand transmission, thereby reducing network resource waste while maintaining service availability when needed
Solution Approach 2:
The patent introduces an uplink feedback mechanism where UEs send feedback information to the network indicating their interest in receiving MBMS services. The MCE processes this feedback and uses it to make activation/deactivation decisions, creating a closed-loop control system that adapts service transmission to actual user demand, thus resolving the contradiction between continuous availability and resource efficiency
2Productivity
If MBMS services are activated based on uplink feedback from all UEs, then resource allocation efficiency is improved, but system complexity increases due to feedback processing
Solution Approach 1:
The patent introduces the MCE as an intermediary network element that centralizes the processing of uplink feedback information from multiple UEs. Instead of each eNB independently processing feedback from its UEs, the MCE collects feedback from all eNBs in the MBSFN area, performs centralized service activation/deactivation decisions, and coordinates transmission. This intermediary approach simplifies individual node complexity while achieving system-wide resource allocation efficiency
Solution Approach 2:
The patent merges the feedback processing function across multiple eNBs into a centralized MCE. By combining the feedback information from all UEs in the MBSFN area and performing unified service activation/deactivation decisions, the system achieves efficient resource allocation without requiring complex distributed processing at each eNB, thus balancing productivity improvement with acceptable system complexity

AI summary
The disclosure provides a method for controlling a Multimedia Broadcast Multicast Service (MBMS), which includes: a network side processes uplink feedback information from User Equipment (UE) and makes an Activation/Deactivation determination on an MBMS service according to the processing result; and the network side activates/deactivates the MBMS service according to the determination result. The disclosure also provides a system for controlling an MBMS service correspondingly. The disclosure can control the activation/deactivation of an MBMS service according to uplink feedback information from UE, thereby improving system efficiency.
