Radio Communication Device Paging Cycle Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio communication systems, particularly in the LTE mode, face limitations in flexibility regarding the paging cycle for devices in the RRC Idle mode, leading to increased power consumption and response delays due to fixed, equal intervals.
Innovation Solution
The system introduces the ability to flexibly switch the paging channel communication cycle using acyclic patterns and cycle switching mechanisms, allowing for varied intervals based on specific requirements and applications, such as MTC terminals, to optimize power usage and response times.

Engineering Contradiction Analysis
1Use of energy by moving object
If the paging cycle is lengthened to reduce power consumption of the UE, then power consumption is reduced, but the delay from when the UE is called to when it responds becomes large
Solution Approach 1:
The patent applies dynamics by making the paging cycle adjustable rather than fixed. The base station can dynamically switch between a first paging cycle and a second paging cycle based on terminal state. When a terminal transitions from connected to idle mode, the base station switches to the second (longer) paging cycle to reduce power consumption. When the terminal needs to be paged, the base station switches to the first (shorter) paging cycle to reduce response delay. This dynamic adjustment resolves the contradiction between power consumption and response delay.
2Device complexity
If a fixed equal interval paging cycle is used for radio communication devices not connected to base station, then system simplicity is maintained, but the degree of freedom of the paging cycle is low
Solution Approach 1:
The patent applies segmentation by dividing the paging cycle into multiple distinct types: a first paging cycle for connected mode terminals and a second paging cycle for idle mode terminals. The base station segments the paging operation based on terminal state, allowing different paging cycles to be applied to different terminal groups. This segmentation enables flexibility in paging cycle selection while maintaining clear management rules, thus improving adaptability without significantly increasing system complexity.

AI summary
Provided is a radio communication device including a radio communication section that communicates by radio with a base station, a storage section that stores information indicating two or more intervals, and a receipt control section that switches, among the two or more intervals, a receiving cycle for receiving a paging channel sent from the base station in an unconnected state with the base station.
