Multiple Paging Listening Intervals in Wireless Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In broadband wireless communication systems, extending the paging cycle to reduce power consumption can lead to increased paging delays due to the potential for missed paging messages until the next scheduled time, especially in Machine-to-Machine (M2M) applications where traffic is sporadic.
Innovation Solution
The method involves determining multiple paging listening intervals within a single paging cycle using a paging spacing value and an initial paging offset, allowing for multiple pagings to occur within a single or multiple paging groups, ensuring timely communication and reducing power consumption by optimizing the distribution of paging offsets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the paging cycle is increased to reduce power consumption, then power saving is improved, but paging delay increases
Solution Approach 1:
The patent divides a single paging cycle into multiple paging sub-cycles, each containing a paging listening interval and a paging unavailable interval. This segmentation allows the terminal to wake up periodically within the larger paging cycle to check for pages, effectively reducing paging delay while maintaining the extended paging cycle for power saving. The paging cycle is segmented into multiple manageable intervals rather than a single continuous wait period.
Solution Approach 2:
The patent implements periodic paging listening intervals within the extended paging cycle. The terminal is configured to wake up at specific periodic intervals (paging listening intervals) to check for incoming pages, then return to sleep mode. This periodic action pattern allows the terminal to balance between power consumption and paging responsiveness by waking up only when necessary within the extended cycle.
2Reliability
If multiple pagings are conducted within one paging cycle, then paging reliability is improved, but device complexity increases
Solution Approach 1:
The patent employs preliminary action by pre-configuring the terminal with multiple paging offsets and paging group information before the actual paging process. The terminal stores the paging cycle, paging offsets, and paging group assignments in advance, allowing it to automatically determine which paging listening intervals to monitor without complex real-time calculations. This pre-prepared configuration simplifies the terminal's paging control logic while enabling multiple pagings within one cycle.

AI summary
An apparatus and method for operating a paging control in a broadband wireless communication system are provided. The method includes receiving paging information used to determine a location of a paging listening interval in an idle mode, determining whether multiple pagings are applied, using a maximum paging number field contained in the paging information, determining locations of a plurality of paging listening intervals in a paging cycle using a paging spacing value and an initial paging offset contained in the paging information, and determining whether the terminal is paged in each of the paging listening intervals.
