Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network search and registration methods face challenges in achieving fast and optimal network selection due to irrevocably written parameters in SIM cards, leading to poor network registration, longer registration times, and higher tariffs.
Innovation Solution
A method and system that dynamically configures optimal parameters in SIM cards based on location information, including prioritizing PLMNs, EHPLMNs, HPLMNs, OPLMNs, UPLMNs, and FPLMNs, using a server to modify these parameters and facilitate quick network search and registration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If SIM card parameters are irrevocably written by carrier, then network registration can be performed, but registration time is long and optimal network cannot be selected
Solution Approach 1:
The patent makes the SIM card parameters dynamic by introducing a server that can modify network parameters (PLMN, RPLMN, EHPLMN, HPLMN, OPLMN, UPLMN, FPLMN) based on real-time location information. The system transitions from static, carrier-written parameters to dynamically adjustable parameters that adapt to current network conditions and user location, enabling fast and optimal network selection.
Solution Approach 2:
The patent implements a feedback mechanism where the server receives location information from the communication terminal, queries the optimal network parameters based on this location data, and then configures the SIM card accordingly. This closed-loop feedback system allows the network registration process to adapt continuously to changing conditions, resolving the contradiction between fast registration and optimal network selection.
2Adaptability or versatility
If all mobile networks are listed in SIM card, then complete network coverage can be achieved, but SIM card size and complexity become unpractical
Solution Approach 1:
The patent introduces a server as an intermediary between the SIM card and the network. Instead of storing all possible network parameters in the SIM card, the server acts as a centralized database that stores comprehensive network information. The SIM card only needs to communicate with the server to obtain the necessary parameters, thus maintaining completeness of network coverage while avoiding SIM card complexity.
Solution Approach 2:
The patent moves the network parameter storage from the two-dimensional constraint of SIM card capacity to the virtually unlimited storage capacity of the server's database. By externalizing the parameter storage to a remote server, the system achieves complete network coverage without being constrained by SIM card size or structural complexity.
3Reliability
If network parameters are fixed in SIM card, then registration can be performed, but registration quality is poor and tariffs are high
Solution Approach 1:
The patent fundamentally changes the network parameters (PLMN, RPLMN, EHPLMN, HPLMN, OPLMN, UPLMN, FPLMN) from fixed values to dynamically selectable values based on location information. The server queries the optimal parameters according to the terminal's current location and configures them in the SIM card, ensuring high-quality registration with appropriate networks while avoiding expensive or unavailable networks, thus improving both reliability and adaptability.
