Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current MBMS services in mobile networks are not optimized for users with varying capabilities, leading to potential low-quality service experiences as they either cannot receive or fully utilize multimedia content due to mismatched transmission configurations.
Innovation Solution
The method involves collecting information on the capabilities of mobile equipment from the radio network controller to select and configure radio bearers that cater to different user classes, allowing for optimized point-to-multipoint or point-to-point transmission based on the collected data, ensuring all users can receive content while high-capability users benefit from higher quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If point-to-multipoint transmission is used to deliver information content to multiple users simultaneously, then resource efficiency is improved, but service quality deteriorates when users have varying device capabilities
Solution Approach 1:
The patent applies local quality by transmitting different quality versions of the same information content to different user groups. High-capability users receive high-quality content while low-capability users receive optimized lower-quality content, allowing each user to receive content appropriate to their device capabilities while using a single point-to-multipoint transmission channel
Solution Approach 2:
The patent changes transmission parameters (such as bit rate, resolution, or compression level) based on user capability profiles. The system dynamically adjusts content parameters to match the receiving device's capabilities, enabling efficient resource utilization while maintaining service quality appropriateness for each user group
2Reliability
If point-to-point transmission is used to ensure optimal service quality for each user, then service quality is improved, but resource efficiency deteriorates
Solution Approach 1:
The patent creates a universal transmission mechanism that can serve multiple user groups simultaneously through a single point-to-multipoint channel. The system is designed to handle both high-capability and low-capability users through the same transmission infrastructure, eliminating the need for separate point-to-point connections while maintaining appropriate service quality for each user type
3Reliability
If transmission configuration is optimized for high-capability users, then service quality for high-capability users is improved, but accessibility for low-capability users deteriorates
Solution Approach 1:
The patent implements local quality by providing different quality levels of the same content to different user groups. High-capability users receive optimized high-quality content while low-capability users receive appropriately optimized lower-quality content, ensuring both groups can access and effectively use the service
Solution Approach 2:
The system dynamically adapts transmission parameters based on real-time user capability information. The network can adjust content delivery parameters on-the-fly according to the receiving device's capabilities, enabling the system to serve both high and low-capability users effectively without fixed configuration
4Adaptability or versatility
If transmission configuration is optimized for low-capability users, then accessibility for low-capability users is improved, but service quality for high-capability users deteriorates
Solution Approach 1:
The patent changes transmission parameters dynamically based on user capability. The system can switch between different content encoding, resolution, or bit rate parameters to match the receiving device's capabilities, ensuring high-capability users receive optimal quality while low-capability users receive accessible content
Data Source
AI summary
A method of transmitting information content to a plurality of mobile equipment, in which information related to the capability of properly decoding the content from a p-t-m radio bearer is collected by the radio network controller from the UEs that have joined the service. The proper configuration for the transmission of the content is then selected based on the collected information.
