Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the access network device is notified of the redundancy in advance, then the transmission can be optimized, but the system cannot adapt to dynamic changes in redundancy
Solution Approach 1:
The patent applies the dynamics principle by transitioning from static pre-notified redundancy configuration to dynamic redundancy determination. The access network device dynamically determines redundancy based on first information carried in data packets, allowing the system to adapt to changing redundancy requirements in real-time without requiring complex pre-configuration mechanisms.
Solution Approach 2:
The patent implements self-service by having the access network device autonomously determine redundancy based on information carried in the data packets themselves. The first information in the protocol data unit header enables the access network device to self-determine redundancy without external notification, simplifying the system while improving adaptability.
2Loss of energy
If all data packets are transmitted, then service reliability is maintained, but air interface resources are wasted
Solution Approach 1:
The patent applies partial action by transmitting only a subset of data packets (M packets) instead of all packets in the PDU set. The access network device determines M based on the redundancy ratio and first information in the packet headers, achieving resource efficiency while maintaining service reliability through selective transmission of essential packets.
Data Source
AI summary
This application provides a communication method and apparatus. First information for determining redundancy of a PDU set by an access network device may be carried in a data packet belonging to a protocol data unit set, that is, the first information is carried in the data packet. This enables dynamic determination of the redundancy of the PDU set, allowing for more flexible adaptation to redundancy determination in a wider range of scenarios, and also saves resources required for transmitting the first information. In addition, the access network device may send some data packets in a plurality of data packets based on the redundancy of the PDU set, thereby saving air interface resources.
