Mobile Terminal Network Access via Geolocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication terminals face inefficiencies in network access when roaming, as they default to searching the current visited public land mobile network (VPLMN) or home public land mobile network (HPLMN) without accurately determining their geographical location, leading to prolonged network searching times and reduced access efficiency.
Innovation Solution
The method involves obtaining geographical location information using GPS and selecting the VPLMN matching that location, adding it to an equivalent public land mobile network (EPLMN) list, and performing a network search and registration using this list, thereby optimizing network access by prioritizing matching networks based on the device's current location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the mobile communication terminal continues to search the currently visited public land mobile network (VPLMN) or home public land mobile network (HPLMN) by default, then the network search process is simple, but the network access efficiency is significantly reduced due to searching for non-matching network coverage
Solution Approach 1:
The patent applies preliminary action by obtaining geographical location information before the network search process begins. The terminal device acquires location data through GPS or other positioning methods, then uses this information to pre-determine the appropriate VPLMN for searching. This preliminary determination of network selection based on location data eliminates the need for extensive searching of non-matching networks, thereby improving network access efficiency without significantly complicating the overall process.
2Loss of time
If the mobile communication terminal uses default network search without geographical location information, then the device operation is simple, but a large amount of time is consumed in network searching
Solution Approach 1:
The patent implements preliminary action by obtaining geographical location information before initiating the network search. The terminal device uses positioning methods such as GPS to acquire location data, then determines the appropriate VPLMN based on this location information. This preliminary step significantly reduces the time required for network searching by directing the search to the correct network from the outset, rather than requiring extensive searches through multiple networks.
Solution Approach 2:
The patent applies mechanics substitution by replacing the traditional mechanical network search approach (systematically searching through VPLMN and HPLMN in a fixed sequence) with a location-based intelligent selection mechanism. Instead of relying on predetermined search orders, the system uses geographical location information to directly identify and connect to the appropriate network, substituting the mechanical search process with a more efficient location-driven selection process.
3Productivity
If the mobile communication terminal searches for network coverage without determining current location, then the search process is straightforward, but the network access efficiency is significantly reduced
Solution Approach 1:
The patent applies preliminary action by obtaining geographical location information through positioning methods such as GPS before the network search process begins. This location data is then used to determine the appropriate VPLMN for searching. By performing this location-based network selection in advance, the system significantly improves network access efficiency, as the terminal device can directly search for and connect to the correct network without needing to search through multiple non-matching networks.

AI summary
Disclosed are a network access method and a mobile communications terminal, said method comprising the following steps: obtaining the geographical location information of a mobile communications terminal; if the geographical location information of said mobile communications terminal is not the home geographical location information of the mobile communications terminal, then selecting, according to the geographical location information of said mobile communications terminal, a visited public land mobile network matching said geographical location information; adding said visited public land mobile network to an equivalent public land mobile network list; searching for a network according to the appended equivalent public land mobile network list, and if the visited public land mobile network is found, then executing a network registration operation for said mobile communications terminal. Using the present invention, it is possible to reduce search time when a mobile communications terminal is searching for a network, and improve network access efficiency.
