Terminal-Specific Cell Reselection Priority List

Solution Overview

Problem

In multi-system mobile communication environments, terminals face challenges in efficiently selecting the best cell for reselection, leading to increased processing power consumption and measurement time due to the lack of effective priority determination methods.

Innovation Solution

A method and system where a network or terminal determines a private priority list for cell reselection based on various factors, with the network delivering this list through special signaling, allowing terminals to evaluate and select cells efficiently by combining private and public priority levels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a terminal performs cell reselection in a multi-system mobile communication environment without effective priority determination methods, then multiple frequencies and cells are available for selection, but the terminal experiences increased processing power consumption and measurement time

Engineering Contradiction:

Improvecell reselection capabilityVSAvoidterminal power consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The network pre-calculates and provides priority information to the terminal before the terminal performs cell reselection. The terminal receives priority lists (public and private) from the network that indicate the preferred order of cell selection across multiple systems and frequencies. This preliminary provision of priority information allows the terminal to avoid exhaustive measurement and evaluation of all available cells, thereby reducing power consumption and measurement time while maintaining adaptability in multi-system environments.

2Adaptability or versatility

If a terminal performs cell reselection in a multi-system mobile communication environment without effective priority determination methods, then multiple frequencies and cells are available for selection, but the terminal experiences increased measurement time

Engineering Contradiction:

Improvecell reselection capabilityVSAvoidmeasurement time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The network pre-calculates and provides priority information to the terminal before the terminal performs cell reselection. The terminal receives priority lists (public and private) from the network that indicate the preferred order of cell selection across multiple systems and frequencies. This preliminary provision of priority information allows the terminal to avoid exhaustive measurement and evaluation of all available cells, thereby reducing power consumption and measurement time while maintaining adaptability in multi-system environments.

3Ease of operation

If the network provides public priority lists to all terminals, then cell reselection is simplified, but terminal-specific optimization is lost

Engineering Contradiction:

Improvecell reselection processVSAvoidterminal-specific optimization

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The priority information is segmented into two distinct components: public priority lists and private priority lists. Public priority lists provide general cell reselection priorities applicable to all terminals, simplifying the basic reselection process. Private priority lists provide terminal-specific optimization based on individual terminal characteristics, service requirements, and network conditions. The terminal combines both types of priority information to achieve both ease of operation and terminal-specific adaptability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different priority information is provided to different terminals based on their specific needs and characteristics. The network assigns private priority lists tailored to individual terminals, allowing each terminal to have optimized reselection behavior suited to its specific service requirements, capabilities, and operational context, while still benefiting from the general guidance of public priority lists.
