Mobile Terminal Location Inquiry via Short Message Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Global Positioning System (GPS) is costly and cumbersome for users, limiting its popularization, and there is a need for a more efficient method to obtain position information using mobile terminals.
Innovation Solution
A method and system where a mobile terminal sends a short message with a specific code to a server to inquire position information, using its Cell ID or WiFi hotspot ID, allowing the server to retrieve and return the position data in a system-defined format, which is then displayed on the terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS satellite navigation system is used to obtain position information, then positioning accuracy is improved, but system cost and complexity increase significantly
Solution Approach 1:
The patent introduces a server as an intermediary component that mediates between the mobile terminal and the positioning database. The terminal sends position inquiry requests to the server, which retrieves location information from databases and returns it to the terminal. This intermediary approach eliminates the need for expensive GPS hardware while maintaining positioning functionality through network-based coordination.
Solution Approach 2:
The patent creates a simplified copy of the positioning function that operates independently of the original GPS system. Instead of requiring expensive satellite navigation hardware, the system creates a virtual positioning service that uses mobile terminal identifiers (Cell ID, WiFi hotspot ID) to access location data from servers, effectively copying the positioning capability at lower cost.
2Adaptability or versatility
If GPS equipment is deployed to provide positioning services, then positioning function is improved, but device cost increases and popularization is hindered
Solution Approach 1:
The patent makes the positioning function universal by enabling any mobile terminal with basic communication capabilities to access positioning services through the server, regardless of whether the terminal has expensive GPS hardware. The system serves multiple types of terminals (cellular phones, WiFi-enabled devices) through a common server-based architecture, greatly enhancing accessibility and popularization.
Solution Approach 2:
The patent replaces expensive, long-term investment in GPS hardware with a cheap, service-based approach where position information is obtained on-demand through short message transmissions to the server. This eliminates the need for users to invest in expensive positioning equipment while maintaining the positioning function.
3Adaptability or versatility
If traditional positioning methods are used, then positioning capability is provided, but user operation becomes cumbersome and efficiency decreases
Solution Approach 1:
The patent implements self-service by enabling the mobile terminal to automatically retrieve its own position information through simple user-initiated requests. The terminal autonomously sends position inquiry messages to the server, receives location data, and can display it without requiring complex manual configuration or professional operation, greatly simplifying user interaction.

AI summary
The present invention belongs to the technical field of the mobile terminal, and discloses a method and system for enquiring location information of the mobile terminal, wherein the method includes that: the mobile terminal receives a location enquiry request input by a user, creates a first short message, and sends the created first short message and an Identifier (ID) of the mobile terminal to a server, wherein a message header of the first short message includes corresponding codes for identifying the location enquiry request; the server parses the first short message to obtain the location enquiry request, obtains the location information of the mobile terminal according to the ID of the mobile terminal, creates a second short message and returns it to the mobile terminal, wherein the second short message includes the location information with the system defined format. The user can conveniently and quickly obtain the required location information, the cost can be hugely saved, and it is advantageous for the popularization of the mobile terminal.
