Network Selection via Pre-stored Radio Map Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network search technologies consume significant time and electrical energy, especially when no radio networks are available, leading to high costs and inefficient network selection processes.
Innovation Solution
A method and system that utilize a navigation device to acquire and store radio network information from an electronic map, allowing for selective network camping based on preset rules, reducing blind searches and energy consumption by only activating network search upon user trigger or periodic updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal performs periodical network search to ensure network availability, then network quality is maintained, but electrical energy consumption increases significantly
Solution Approach 1:
The patent applies preliminary action by pre-acquiring radio network information about locations from an electronic map before the terminal actually needs to search for networks. This stored information is then used to guide network selection, avoiding the need for continuous periodical searches and reducing energy consumption while maintaining network quality.
Solution Approach 2:
The patent introduces an intermediary mechanism - the electronic map containing pre-stored radio network information - that mediates between the terminal and actual network searching. Instead of directly searching for networks periodically, the terminal uses this intermediary information to make informed network selection decisions, reducing the frequency and energy cost of searches.
2Loss of information
If the terminal searches all radio networks at its location one by one, then complete network information is obtained, but time consumption and cost increase
Solution Approach 1:
Radio network information about various locations is pre-acquired and stored in an electronic map before the terminal needs it. This preliminary collection of network information eliminates the need for time-consuming searches when the terminal actually needs to connect, while still providing complete network information for informed selection.
Solution Approach 2:
The patent creates a copy of radio network information by storing it in an electronic map. Instead of searching for networks directly, the terminal accesses this copied information from the electronic map, which contains pre-collected data about radio networks at different locations. This copying approach preserves network information completeness while dramatically reducing search time.
3Reliability
If the terminal performs network search when no radio network exists at location, then network availability is ensured, but electrical energy is wasted
Solution Approach 1:
The electronic map is pre-populated with radio network information about locations. Before the terminal performs any network search, it can query this pre-acquired information to determine whether radio networks exist at its current location, avoiding wasted energy on searches in areas where no networks are available.
Solution Approach 2:
The system implements feedback by using pre-acquired radio network information from the electronic map to guide network search decisions. The terminal queries the electronic map for network information about its location, and based on this feedback, decides whether to proceed with network searching or avoid it, thereby preventing energy waste in areas without available networks.
