Adaptive Paging Resource Allocation for Wireless Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In ad hoc peer-to-peer wireless networks, existing paging methods are inefficient in terms of power consumption and latency, especially for applications requiring frequent connection setups and teardowns, as they increase overhead and power usage when increasing the frequency of paging channels.
Innovation Solution
An adaptive paging method where wireless devices determine a subset of available paging resources and transmit information about these resources in a peer discovery signal, reducing power consumption and congestion, thereby minimizing false alarms and misdetections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the frequency of the paging channel is increased to reduce setup latency, then connection setup time is reduced, but overhead and power consumption increase
Solution Approach 1:
The patent implements dynamic paging resource allocation where wireless devices determine a subset of available paging resources based on their specific needs and transmit information about these resources in peer discovery signals. This allows the paging frequency and resource allocation to be dynamically adjusted per device rather than using a fixed high-frequency paging channel for all devices, thereby reducing overall power consumption while maintaining low setup latency for devices that require it.
Solution Approach 2:
The patent applies local quality by allowing different wireless devices to use different paging resource subsets tailored to their specific communication requirements. Devices with machine-to-machine communication needs can allocate more frequent paging resources, while other devices use less frequent resources, optimizing power consumption locally for each device rather than uniformly across the network.

AI summary
A method, a computer program product, and an apparatus are provided. The apparatus determines paging resources of a plurality of paging resources allocated for listening to paging messages. In addition, the apparatus transmits information indicating the allocated paging resources in a peer discovery signal. The apparatus may determine the paging resources on which to listen based on information received in peer discovery signals received from other wireless devices. The received information indicates the paging resources allocated to the other wireless devices.
