Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If only SSID and MAC address are used for identification, then the identification process is simple, but homonymic wireless access points cannot be distinguished
Solution Approach 1:
The patent introduces additional identification dimensions beyond SSID and MAC address by incorporating position information (latitude, longitude, altitude) and adjacent base station information. This multi-dimensional approach allows differentiation of homonymic access points by comparing their spatial locations and surrounding infrastructure, resolving the identification ambiguity while maintaining operational simplicity.
2Measurement precision
If access point assistant information is collected and compared, then identification accuracy is improved, but system complexity increases
Solution Approach 1:
The patent implements preliminary collection and storage of access point assistant information (position data, adjacent base station information) in a database before actual identification operations. This pre-processing approach ensures that when identification is needed, the comparison can be performed quickly using pre-collected data, reducing real-time computational complexity while maintaining high identification accuracy.
3Reliability
If multiple identification parameters are used, then homonymic access points can be distinguished, but data matching efficiency decreases
Solution Approach 1:
The patent segments the identification process into hierarchical stages: first comparing SSID and MAC address (basic identification), then position information (spatial identification), and finally adjacent base station information (environmental identification). This segmented approach allows the system to quickly eliminate mismatches at each stage, improving overall data matching efficiency while maintaining reliable differentiation of homonymic access points.

AI summary
The purpose of the present application is to provide a method and equipment for distinguishing homonymic wireless access points through comparing the access point assistant information of the first wireless access point and the second wireless access point which are homonymic, including using the position information, the adjacent base station information, or the adjacent access point information, etc. of the wireless access point. The homonymic wireless access points are further distinguished. Thus, the information of wireless access point is accurately described.
