Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the access network device executes tag inventory/paging procedure on all terminal devices by using a broadcast message, then the terminal device information can be obtained, but the system overhead increases and the efficiency decreases when the need for enterprise device or network is not constant
Solution Approach 1:
The patent introduces dynamic triggering mechanism where the broadcast message is sent only when needed based on actual network requirements. The network can dynamically decide to send broadcast messages for tag inventory/paging procedures based on current needs, rather than continuously or for all terminal devices unconditionally, thereby reducing system overhead while maintaining efficiency.
Solution Approach 2:
The patent segments the terminal devices into different groups based on location information and other criteria. Instead of treating all terminal devices uniformly, the system divides them into segments (e.g., based on area, location, or other attributes) and applies targeted paging strategies to each segment, reducing the overall overhead while maintaining the ability to obtain information about specific terminal devices when needed.
2Adaptability or versatility
If the access network device sends broadcast message to all terminal devices, then the terminal device information can be obtained, but the flexibility to obtain information based on actual requirement is reduced
Solution Approach 1:
The patent applies local quality by tailoring the paging strategy to specific local characteristics of terminal devices. The system determines location information and other attributes of terminal devices, and then applies different paging strategies based on these local characteristics. This allows the network to flexibly obtain information about specific terminal devices based on actual requirements rather than uniformly treating all devices the same way.
Solution Approach 2:
The patent implements preliminary action by pre-configuring and pre-processing location information and other attributes of terminal devices before the actual paging operation. The network maintains location information and other data in advance, so when a paging operation is needed, the system can quickly filter and select the appropriate terminal devices based on pre-existing information, enabling flexible and efficient information retrieval based on actual network requirements.

AI summary
This application proposes a communication method and apparatus. The method includes: A first communication apparatus determines first identification information and first indication information, where the first identification information includes first location information and identifies a terminal device that matches the first location information, and the first indication information indicates the terminal device that matches the first location information to perform a first operation, and/or indicates a terminal device that does not match the first location information to perform a second operation. The first communication apparatus sends a broadcast message including the first identification information and the first indication information. According to the method, the first communication apparatus may flexibly query and obtain information about a corresponding terminal device based on an actual requirement, so that a network can efficiently manage the terminal device.
