Location Zone Selection for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for updating a mobile communication terminal's location zone in standby mode consume excessive resources and battery power, as they rely solely on the terminal identifying its location area based on broadcasted identifiers without considering network conditions or additional data.
Innovation Solution
A method that broadcasts an identifier of the current location zone along with additional location data, allowing the network to select a new location zone based on load levels and other parameters, reducing the need for frequent location updates by considering network conditions and terminal-specific parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal performs periodic location updates in standby mode, then the network can track the terminal's location, but the terminal's battery is discharged more quickly due to resource consumption
Solution Approach 1:
The network performs preliminary actions by proactively selecting and assigning a new location zone to the terminal before the terminal needs to update its location. The network equipment selects a current location zone from multiple zones based on load levels and other parameters, then sends a command message to the terminal with the identifier of this pre-selected location zone, eliminating the need for the terminal to perform resource-intensive location update procedures
Solution Approach 2:
The network equipment acts as an intermediary that manages the location zone selection process. Instead of the terminal autonomously determining its location zone based solely on broadcast identifiers, the network equipment intermediates by selecting the appropriate location zone from multiple candidate zones using supplementary location data and predetermined selection parameters, then communicating this selection to the terminal
2Measurement precision
If the terminal updates its location frequently, then the location information remains current, but network resources and terminal resources are wasted
Solution Approach 1:
The invention changes the parameters used for location zone selection from terminal-centric parameters to network-centric parameters. The network equipment uses supplementary location data including at least one identifier of another location zone, load levels of network equipment, and type of equipment that ensured the switch to standby mode to select the current location zone. This parameter change allows the network to optimize location assignments based on overall network conditions rather than just terminal position, reducing unnecessary location updates
3Device complexity
If the network uses only broadcasted location zone identifiers, then the system is simple, but it cannot adapt to network conditions or optimize resource usage
Solution Approach 1:
The network equipment performs preliminary processing of location information by maintaining supplementary location data that includes identifiers of multiple location zones. Before a terminal needs location information, the network has already prepared this supplementary data and can quickly select an appropriate location zone based on current network conditions, avoiding the need for complex real-time calculations when a terminal requests location information
Solution Approach 2:
The system transitions from a static location zone assignment based solely on broadcast identifiers to a dynamic selection process. The network equipment selects the current location zone from multiple candidate zones based on dynamic parameters including load levels and equipment type, allowing the system to adapt to changing network conditions while maintaining simplicity through pre-prepared supplementary location data
