Device-to-Device Network Feedback Sharing for Access Terminal Power Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face inefficiencies in determining whether an access point can meet a terminal's service or performance needs without camping on it, leading to unnecessary power and resource consumption through trial and error.
Innovation Solution
Access terminals use device-to-device (D2D) links to share network feedback information, allowing them to determine if another access point can provide desired services without direct network configuration data, by composing and transmitting network feedback expressions (NFEs) between terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access terminals use trial and error to determine whether an access point can meet service needs, then service compatibility can be verified, but power consumption and resource usage increase
Solution Approach 1:
The patent applies preliminary action by having access terminals share network feedback information about access point service capabilities before other terminals attempt to camp on those access points. This advance information sharing allows terminals to avoid unnecessary trial-and-error camping attempts, thereby reducing power consumption while ensuring service compatibility can be verified in advance through the shared feedback data
Solution Approach 2:
The patent implements feedback by creating a network feedback information sharing mechanism where terminals that have successfully camped on access points provide feedback about service capabilities to other terminals. This feedback loop enables receiving terminals to make informed decisions about which access points to camp on, avoiding wasted power on incompatible access points while maintaining reliable service compatibility verification
2Use of energy by moving object
If access terminals share network feedback information using D2D links, then power consumption is reduced, but device complexity increases
Solution Approach 1:
The patent applies universality by designing the network feedback information sharing mechanism to operate over existing device-to-device communication links that terminals already have established for other purposes. By reusing existing D2D communication infrastructure rather than creating dedicated feedback channels, the patent reduces power consumption through efficient communication while avoiding excessive device complexity that would result from building entirely new communication protocols
Solution Approach 2:
The patent implements self-service by enabling access terminals to autonomously generate, share, and process network feedback information about access point service capabilities without requiring complex centralized coordination. Each terminal independently manages its own feedback information sharing, which reduces overall system complexity while achieving power savings through avoided trial-and-error camping attempts

AI summary
Systems and methods are disclosed for sharing network feedback information. The method may include establishing, at a first access terminal, a wireless link with an access point, receiving network configuration data from the access point, composing a network feedback expression that indicates a status or availability of at least one network service associated with the access point, and transmitting the network feedback expression to a second access terminal via a D2D link.
