Modular MBMS Service Delivery for Flexible Multimedia Broadcast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems lack flexibility in deploying and delivering third-party multimedia content, such as mobile TV, due to limitations in utilizing network resources for multimedia broadcast and multicast services (MBMS).
Innovation Solution
The system allows an application server to selectively choose a subset of MBMS service delivery functionalities supported by a network device for transmitting multimedia content to mobile devices, including the allocation of a temporary mobile group identity (TMGI) to authorized servers, enabling flexible and efficient communication between application servers and user equipment (UEs).
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional systems deploy MBMS services with fixed network configurations, then network management is simplified, but flexibility in utilizing network resources for third-party multimedia content is reduced
Solution Approach 1:
The patent segments the MBMS service delivery into distinct functional components: content protection functionality, file repair functionality, and bootstrapping functionality. This segmentation allows the network device to selectively activate only the required functionalities for each service deployment, providing flexibility without requiring full implementation of all MBMS features. The segmented approach enables third-party application servers to utilize specific functionalities while maintaining manageable system complexity.
Solution Approach 2:
The patent implements dynamic service delivery by allowing the network device to adaptively select and activate different MBMS functionalities based on service requirements. The system dynamically configures service delivery parameters including content protection mechanisms, file repair options, and bootstrapping procedures. This dynamic adaptation enables the network to flexibly respond to different third-party multimedia content delivery scenarios while maintaining operational simplicity through automated functionality selection.
2Adaptability or versatility
If the network device activates all MBMS functionalities, then service coverage is maximized, but network resource consumption increases
Solution Approach 1:
The patent extracts and isolates specific MBMS functionalities (content protection, file repair, bootstrapping) that can be independently activated. Instead of deploying the complete MBMS service suite, the network device extracts and activates only the necessary functionalities for each specific service scenario. This extraction approach ensures comprehensive service coverage for required features while avoiding the resource consumption associated with activating unnecessary functionalities.
Solution Approach 2:
The patent changes the operational parameters of the MBMS service delivery by selectively activating specific functionalities based on service requirements. The network device adjusts service delivery parameters including enabling/disabling content protection, file repair, and bootstrapping functionalities. This parameter-based control allows the system to maximize service coverage for required features while minimizing network resource consumption by keeping unnecessary functionalities in an inactive state.
3Adaptability or versatility
If third-party application servers are integrated into the network, then service diversity increases, but security risks and authorization complexity increase
Solution Approach 1:
The patent introduces an intermediary authorization mechanism where the network device acts as a mediator between third-party application servers and the MBMS service delivery infrastructure. The network device verifies authorization credentials and manages security protocols, allowing service diversity from multiple third-party servers while maintaining centralized security control. This intermediary approach enables diverse service providers to integrate without directly compromising network security, as the network device mediates all authorization and security-related interactions.
