Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G and 6G network access procedures are complex and time-consuming for new users, requiring multi-step processes that involve blind searches for base stations, complex computations, and significant delays, which are challenging for low-cost, reduced-capability devices like IoT applications.
Innovation Solution
A network database system that allows user devices to automatically locate and connect to the nearest base station by downloading location-specific information, determining the closest base station, and transmitting access requests without human intervention, using simplified communication protocols that reduce computational burden and delay.

Engineering Contradiction Analysis
1Reliability
If traditional multi-step base station discovery and registration processes are used, then network authentication and connection are achieved, but the process becomes complex and time-consuming with significant delays
Solution Approach 1:
The patent applies preliminary action by having the user device obtain and store system information from the selected base station before the actual access process. The device receives system information including broadcast channel frequency and random access channel frequency in advance, allowing it to prepare all necessary parameters before initiating connection, thereby eliminating time-consuming real-time searches during the access process itself.
Solution Approach 2:
The patent introduces an intermediary approach by using a database that stores pre-configured base station information. Instead of directly performing complex blind searches across multiple base stations in real-time, the user device queries this intermediary database to obtain filtered and pre-processed base station information, significantly reducing the computational burden and access time.
2Ease of operation
If traditional blind search methods are used to locate base stations, then base station discovery is achieved, but computational complexity and processing requirements increase significantly
Solution Approach 1:
The patent uses a database as an intermediary that stores pre-processed base station information including locations, frequencies, and system parameters. The user device simply queries this database rather than performing complex blind searches, dramatically reducing computational complexity while maintaining ease of base station discovery.
Solution Approach 2:
The system performs the complex computational tasks of base station search and parameter extraction in advance during network setup, storing the results in the database. When a user needs access, the device only needs to query pre-computed information, avoiding the computational burden of real-time analysis.
3Reliability
If multiple registration steps are performed sequentially, then proper network registration is achieved, but the overall process time increases significantly
Solution Approach 1:
The patent applies preliminary action by having the user device receive and store all necessary system information parameters in advance, including broadcast channel frequencies, random access channel frequencies, and timing information. This allows the device to skip intermediate verification steps during actual access, performing registration more rapidly while maintaining reliability.
Solution Approach 2:
The patent enables continuous progression through registration steps by having all necessary information ready in advance. Instead of stopping to search for parameters between steps, the device can continuously execute registration operations using pre-obtained data, improving productivity without compromising the completeness of the registration process.

AI summary
A searchable, portable network database of base station information can greatly simplify discovery, selection, and registration of user devices on a preferred cell in 5G or 6G. In addition, based on location, the user device can select the base station that is likely to provide the best signal. The network database can provide all of the static system information of the SSB message, which enables prospective user devices to receive downlink messages without searching for the SSB. In addition, the network database can provide all of the static system information contained in the SIB1 message, which enables prospective user devices to transmit uplink messages without searching for the SIB1. Initial synchronization can be obtained by receiving any broadcast from the base station, or by receiving timing signals from a navigation satellite, among other ways. The user device can thereby avoid most or all of the arduous prior-art cell discovery steps.
