Dynamic Paging Cycle Adjustment in Wireless Idle Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems face challenges in balancing power savings and rapid response to traffic in idle mode due to fixed paging cycles, which require inconvenient transitions between idle and normal modes, and are inefficient in resource utilization when the number of available Mobile Stations (MSs) is limited.
Innovation Solution
A method and apparatus that allow Mobile Stations (MSs) to transmit a RaNGing REQuest (RNG-REQ) message to change the paging cycle while in idle mode, with the Base Station (BS) responding with updated paging information, enabling flexible adjustment of the paging cycle based on conditions such as traffic generation and power consumption needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the paging unavailable interval is extended to increase power efficiency, then power consumption is reduced, but the response time to traffic increases
Solution Approach 1:
The patent applies dynamics by making the paging cycle configurable and adjustable based on MS requirements. The BS receives a requested paging cycle from the MS and computes a substantial paging cycle that balances power efficiency and response time. This dynamic adjustment allows the system to optimize between power consumption and response time rather than using a fixed paging cycle.
Solution Approach 2:
The patent changes the paging cycle parameter to resolve the contradiction. The MS can request a specific paging cycle, and the BS computes a substantial paging cycle that may differ from the requested value. This parameter adjustment mechanism allows the system to find an optimal balance between power efficiency (longer paging cycle) and response time (shorter paging cycle).
2Adaptability or versatility
If the MS transitions to normal mode to change the paging cycle, then the paging cycle can be adjusted, but resource utilization of the BS deteriorates and mode transition complexity increases
Solution Approach 1:
The patent makes the ranging message serve multiple functions: it is used for both initial network access and for requesting paging cycle changes while in idle mode. This multi-functionality eliminates the need for separate mode transitions to change paging cycle parameters, reducing complexity while maintaining adaptability.
Solution Approach 2:
The MS can autonomously request a paging cycle change by including the requested paging cycle in the ranging message it transmits to the BS. The system allows self-service configuration without requiring mode transitions or complex manual intervention, simplifying the overall process.

AI summary
An apparatus and method for operating an idle mode in a wireless communication system are provided. The method includes transmitting, by a Mobile Station (MS) to a Base Station (BS), a RaNGing REQuest (RNG-REQ) message for changing a paging cycle while operating the idle mode; transmitting, by the BS to the MS, a RaNGing ReSPonse (RNG-RSP) message including paging information to be changed; and operating a new idle mode by the MS and the BS according to the paging information transmitted and received while operating the idle mode.
