Selective Multimedia Broadcast Reception via Terminal ID Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia broadcast/multicast services in cellular networks are not cost-effective due to high network resource usage and lack of user-based subscription control, leading to higher operational costs and subscriber rates, which reduces service demand and revenue for operators.
Innovation Solution
The Multimedia Broadcast Selective Receive Service (MBSRS) architecture combines broadcasting with user-based subscription control, allowing users to selectively receive desired multimedia content by matching terminal content IDs with broadcasted content IDs, reducing network resource usage and enabling efficient content delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If peer-to-peer transmission is used to deliver multimedia content, then users can receive desired content selectively, but network resource consumption increases and operational costs rise
Solution Approach 1:
The patent segments the content delivery process into two distinct phases: (1) a broadcast phase where content information and identifiers are transmitted to all users, and (2) a selective reception phase where users' terminals filter and receive only their desired content based on pre-configured preferences. This segmentation allows the network to use efficient broadcast for content distribution while enabling user-specific selection without requiring separate peer-to-peer connections for each user-content pair.
Solution Approach 2:
The patent implements preliminary action by having users pre-configure their content reception preferences and filters before the broadcast begins. The terminal devices store user-specific content identification criteria in advance, allowing them to autonomously filter broadcast content without real-time network intervention. This preliminary configuration enables selective content reception to be achieved through local processing rather than network-controlled individual deliveries.
2Ease of operation
If MBMS multicast function is used to provide subscriber management, then comprehensive control is achieved, but substantial overhead processing is introduced in all nodes and interfaces
Solution Approach 1:
The patent extracts the complex subscriber management and content filtering functions from the network nodes and relocates them to the user terminals. Instead of requiring network nodes to process and manage individual subscriber preferences and perform content filtering, the system places these functions in the terminal devices where users can independently configure and execute content selection based on broadcast information.
Solution Approach 2:
The patent implements self-service by enabling terminal devices to autonomously perform content filtering and selection without requiring continuous network intervention or complex processing in network nodes. Users' terminals independently compare broadcast content identifiers against their pre-configured preferences and automatically receive only matching content, eliminating the need for substantial overhead processing in network infrastructure.
3Loss of energy
If broadcast service is used to deliver content to multiple users, then network resource usage is reduced, but user-based subscription control and selective content reception are lost
Solution Approach 1:
The patent introduces dynamics by making the broadcast system adaptive to individual user preferences. While the broadcast transmission itself remains static and efficient for network resource utilization, the reception端 dynamically filters and selects content based on user-specific criteria. This dynamic filtering at the terminal level enables selective subscription control without compromising the efficiency of the broadcast delivery mechanism.
Solution Approach 2:
The patent adds another dimension to the broadcast system by introducing a user preference configuration layer. Instead of purely network-controlled or purely generic broadcast delivery, the system operates in two dimensions: the network dimension for efficient content distribution and the user dimension for personalized content selection. This dimensional addition enables selective subscription control while preserving broadcast efficiency.
Data Source
AI summary
A multimedia communications system for broadcast distribution of multimedia content to mobile terminals over a cellular network is disclosed. The disclosed system accesses content providers, receives corresponding content information associated with provider content, and broadcasts content information to user terminals. The user terminals include software and/or hardware for receiving the content information and enabling a user to subscribe to one or more content items. Once a subscription is in place for one or more content items, corresponding content IDs are sent to and stored at the terminal. The system facilitates broadcast of the content. Content IDs stored in the terminal and broadcasted content IDs are compared. Only the content associated with the matching content IDs is then downloaded to the user terminal for storage and/or presentation. Content associated with unmatched content IDs is prevented from being received.
