Innovation Solution
Implement a method and apparatus in cellular networks to identify and process passive or semi-active IoT instructions and responses using specific protocols, such as LLRP, by recognizing session types and tunnel identifiers, enabling seamless integration and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cellular networks integrate passive or semi-active IoT technologies, then IoT application support capability is improved, but packet parsing and processing capability deteriorates
Solution Approach 1:
The patent introduces an access network device as an intermediary component between the IoT function network element and the cellular network core. This access network device is specifically configured to parse IoT application packets and extract IoT instructions, thereby enabling the cellular network to handle passive or semi-active IoT applications without requiring core network modifications. The intermediary absorbs the complexity of packet parsing at the access level.
2Productivity
If access network devices parse IoT packets, then IoT instruction processing is improved, but network device complexity increases
Solution Approach 1:
The patent segments the network functions by placing the packet parsing and IoT instruction extraction capabilities specifically in the access network device, separate from the core network elements. This segmentation allows the access network device to handle IoT-specific packet formats (such as LLRP protocol packets) independently, while the core network maintains its existing simplified architecture for handling processed IoT instructions.

AI summary
Embodiments of this application disclose a packet transmission method and a related apparatus. An access network device receives a first packet from an Internet-of-things (IoT) function network element; the access network device obtains first information, where the first information indicates that the first packet includes a passive or semi-active IoT instruction; and the access network device performs a passive or semi-active IoT operation based on the first packet. According to the foregoing method, the access network device learns that the packet from the IoT function network element is related to a passive or semi-active internet of things, and the access network device performs the passive or semi-active IoT operation based on the first packet. This resolves a packet transmission problem in a scenario in which a passive or semi-active IoT system is converged with a cellular network.
