Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems lack a method for efficient conversion between different transmission modes, such as point-to-point and point-to-multipoint, leading to suboptimal utilization of network resources.
Innovation Solution
A method and system for indicating transmission mode conversion by sending messages with user and multicast group information to trigger mode changes in base stations, network function nodes, and terminal devices, allowing flexible switching between dedicated, shared, unicast, and multicast modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If point-to-point transmission mode is used, then service quality for individual user is improved, but network resource utilization is worsened
Solution Approach 1:
The patent implements dynamic transmission mode conversion allowing the system to switch between point-to-point and point-to-multipoint modes based on real-time conditions. The base station can convert from dedicated mode to shared mode when multiple users have same content needs, and revert to dedicated mode when users have different needs, optimizing resource utilization while maintaining service quality.
Solution Approach 2:
The patent changes the transmission mode parameter from fixed to variable. By introducing conversion mechanisms between different transmission modes (dedicated, shared, unicast, multicast), the system can adapt the transmission parameter based on user requirements and network conditions, resolving the contradiction between service quality and resource utilization.
2Loss of energy
If point-to-multipoint transmission mode is used, then network resource utilization is improved, but transmission flexibility is worsened
Solution Approach 1:
The system dynamically switches between transmission modes based on user requirements. When users have same content needs, the system converts to shared/multicast mode for efficient resource utilization. When users have different needs, the system converts to dedicated/unicast mode for transmission flexibility, thus resolving the contradiction.
Solution Approach 2:
The base station is designed with multi-functionality to support both point-to-point and point-to-multipoint transmission modes. This universal capability allows the system to serve different user scenarios flexibly, maintaining both resource utilization efficiency and transmission adaptability.
3Loss of energy
If transmission mode conversion is implemented, then network resource utilization is improved, but system complexity is worsened
Solution Approach 1:
The base station acts as an intermediary that handles transmission mode conversion between the core network and terminal devices. By centralizing the conversion function at the base station level, the system avoids complex conversions throughout the entire network, simplifying the overall system architecture while achieving efficient resource utilization.
Solution Approach 2:
The system uses feedback mechanisms where terminal devices indicate their transmission mode requirements to the base station. This feedback-driven approach enables automatic mode selection and conversion without complex centralized control, reducing system complexity while optimizing resource allocation based on actual user needs.

AI summary
A transmission mode conversion indication method includes: sending a first message to a core network or sending a second message to a terminal device, so as to indicate that a transmission mode conversion is required, where the first message carries first user information and first multicast group information.
