Broadcast Video Provisioning System for eMBMS Small Cell Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The 3GPP has not defined how to provision small cells, such as those provided by eNodeBs, for efficient delivery of eMBMS services, particularly in scenarios like stadiums or concert halls, leading to inefficient network resource allocation and customer experience issues.
Innovation Solution
The system dynamically configures an access network for eMBMS single frequency networks, allowing multiple small cells to broadcast the same information with reserved bandwidth during events and switching to unicast services post-event, using a broadcast video provisioning system to manage cell capacity and content delivery across regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If small cells are provisioned for eMBMS services, then network coverage and service delivery are improved, but network resource allocation efficiency deteriorates due to lack of defined provisioning mechanisms
Solution Approach 1:
The system performs preliminary actions by pre-provisioning small cells with eMBMS capability before events occur. The broadcast video provisioning system (BVPS) pre-configures cell parameters, service area templates, and bandwidth reservations so that when an event is detected, the small cells can immediately switch to broadcast mode without requiring real-time provisioning adjustments.
Solution Approach 2:
The system dynamically adjusts cell operation modes based on event detection. Small cells can switch between unicast and broadcast modes, and between different service area templates (e.g., stadium-specific vs. general coverage) depending on the event type and requirements. This dynamic reconfiguration optimizes resource allocation while maintaining reliable service delivery.
2Reliability
If bandwidth is reserved for broadcast services during events, then customer experience is improved, but network bandwidth consumption increases
Solution Approach 1:
The system applies local quality by reserving bandwidth only in specific small cells located at event venues rather than reserving bandwidth network-wide. Each small cell is individually configured with appropriate bandwidth reservations based on its location and the specific event, allowing high-quality broadcast service where needed while conserving bandwidth elsewhere in the network.
Solution Approach 2:
The system uses periodic action by establishing bandwidth reservations for limited durations corresponding to event timeframes. After the event concludes, the reserved bandwidth is released and reallocated to other services, preventing continuous bandwidth consumption while ensuring adequate resources during the event period.
3Area of stationary object
If multiple small cells broadcast the same content, then service coverage is improved, but network complexity increases due to coordination requirements
Solution Approach 1:
The broadcast video provisioning system (BVPS) serves as a universal coordination platform that manages multiple small cells independently of individual cell implementations. The system uses standardized templates and interfaces that can be applied across different vendors and cell types, reducing coordination complexity while expanding service coverage through multi-cell broadcast.
Solution Approach 2:
The system segments the broadcast network management into independent components: the BVPS handles high-level coordination and template management, while individual small cells handle local execution. This segmentation allows each component to operate semi-independently, reducing the complexity of coordinating multiple cells while maintaining unified service coverage.
4Productivity
If small cells are configured for broadcast mode, then content delivery efficiency is improved, but adaptability to different service types deteriorates
Solution Approach 1:
The system dynamically adapts cell configuration based on service requirements. Small cells can switch between broadcast and unicast modes, and the BVPS can apply different service area templates depending on the event type (e.g., sports events requiring venue-specific coverage vs. concerts requiring broader coverage). This dynamic adaptability maintains high content delivery efficiency while preserving versatility across different service types.
Solution Approach 2:
The BVPS employs universal templates and configuration frameworks that can accommodate multiple service types through a single system. The same broadcast video provisioning infrastructure supports various events and service requirements by applying different parameters and templates, eliminating the need for separate specialized systems for each service type.

AI summary
A device receives, from a network device, information associated with an event, and assigns an event identifier to the event based on the event information. The device also provides the event identifier to a cell control device located at a location associated with the event, and determines a cell capacity of the location to ensure that there is sufficient cell capacity at the location to broadcast the event. The network device instructs a device capturing the event to provide live event data to the cell control device for a predetermined time period.
