Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a channel is configured for broadcast business in conventional communication systems, then the broadcast business can be transmitted, but compatibility with multiple access technologies cannot be achieved
Solution Approach 1:
The patent creates a unified channel configuration method that works across multiple access technologies (Bluetooth, Wi-Fi, etc.). The basic service layer establishes a standardized broadcast business channel that can adapt to different access technologies, making the channel configuration universal rather than technology-specific. This allows the same channel configuration procedure to serve multiple access technologies simultaneously.
Solution Approach 2:
The patent implements a layered architecture where the basic service layer (with broadcast business channel) is nested within the access layer. The access layer supports multiple access technologies and contains the basic service layer, which in turn contains the application layer. This nested structure allows channel configuration to be performed at the appropriate layer while maintaining compatibility across technologies.
2Reliability
If channel configuration is performed to meet specific business requirements, then transmission quality is improved, but flexibility across different access technologies deteriorates
Solution Approach 1:
The patent applies different configuration details at different layers: the basic service layer handles standardized channel configuration parameters that ensure transmission quality, while the access layer handles technology-specific adaptations. This allows local optimization for each access technology while maintaining overall transmission quality standards through the unified basic service layer configuration.

AI summary
Embodiments of this application provide a channel configuration method and an apparatus, and relate to the field of communication technologies, to configure a channel for transmission of broadcast business. The method includes: A basic application layer sends first information that includes a first business requirement and a first port to a basic service layer. The basic service layer sends second information that includes the first business requirement, a first broadcast business channel, and a logical channel type to an access layer. The first broadcast business channel is determined based on the first information. The access layer supports a first access technology that is determined, based on the first business requirement, from a plurality of access technologies supported by the access layer. The access layer sends a first mapping relationship that indicates the first broadcast business channel and a first logical channel to the basic service layer. The first logical channel is a logical channel that supports the first access technology and that is determined based on the second information. The basic service layer stores a second mapping relationship indicating the first broadcast business channel and the first port. In this way, channel configuration is completed.
