Solution Overview
Problem
Current wireless communication systems face challenges in conserving battery power, particularly in multi-carrier systems, where high overhead and power consumption are incurred due to signaling design limitations, affecting battery life and system capacity.
Innovation Solution
A method is introduced where an access terminal (AT) and access network (AN) communicate through notification and confirmation messages to determine and implement power-saving modes, adjusting paging cycles and signal processing based on battery life information, reducing signaling overhead and power consumption.

Engineering Contradiction Analysis
1Duration of action of moving object
If signaling design is improved to save battery power, then battery life is extended, but system complexity increases due to additional notification and confirmation message protocols
Solution Approach 1:
The access terminal sends a notification message in advance indicating its power-saving mode request or battery life information before actually entering power-saving mode. This preliminary action allows the access network to prepare appropriate confirmation messages and scheduling decisions, reducing the need for complex real-time negotiations when the terminal actually needs to save power.
Solution Approach 2:
The access network responds to the terminal's notification with a confirmation message that includes determined power-saving mode parameters based on the terminal's battery life information and power-saving mode request. This feedback mechanism creates a closed-loop system where the network adapts its scheduling and resource allocation based on terminal power status, enabling efficient power management without excessive complexity.
2Duration of action of moving object
If power-saving modes are implemented to reduce battery consumption, then battery life increases, but system capacity may be reduced due to adjusted paging cycles and signal processing
Solution Approach 1:
The system dynamically adjusts power-saving mode parameters including paging cycles and signal processing levels based on real-time battery life information provided by the terminal. Instead of using fixed power-saving configurations, the network can flexibly modify operational parameters to balance power consumption with system capacity requirements, allowing terminals with critical battery levels to enter deeper sleep modes while maintaining adequate network responsiveness.
Solution Approach 2:
The confirmation message from the access network includes determined power-saving mode parameters that are specifically tailored based on the terminal's battery life information. By changing operational parameters such as paging cycle lengths, measurement intervals, and signal processing depths according to battery status, the system optimizes power savings while minimizing impact on overall system capacity and performance.

AI summary
A method of executing to battery power consumption between an access terminal (AT) and an access network (AN) in a wireless communication system is disclosed. More specifically, the method includes transmitting a notification message to the AN, receiving a confirmation message from the AN, and entering the power-saving mode according to the determined power saving mode. Here, the notification message includes at least one of battery life information and a power-saving mode request, and the confirmation message includes a determined power saving mode which is based on the at least one of battery life information and the power-saving mode request.
