Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices executing proxy processing in wireless communication systems cannot determine when to continue or interrupt proxy processing due to target device movement or unintended power disconnection, leading to unnecessary resource wastage.
Innovation Solution
A proxy apparatus and communication apparatus equipped with processors and memories that manage proxy processing based on Wi-Fi NAN standards, including an acceptance unit for active period messages, an execution unit for proxy processing, and a confirmation unit to verify communication with the proxy apparatus during active periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If proxy processing is continued without confirmation, then service availability is maintained, but resource wastage increases
Solution Approach 1:
The patent implements a feedback mechanism where the proxy apparatus periodically receives confirmation messages from the proxy client to verify its continued existence and communicability. This feedback loop allows the system to maintain proxy processing only when necessary, preventing resource wastage while ensuring service availability through timely detection of client status changes.
Solution Approach 2:
The patent employs periodic confirmation messages exchanged between the proxy apparatus and proxy client at defined intervals. This periodic action enables the system to balance between maintaining service availability (by continuing proxy processing) and reducing resource consumption (by interrupting proxy processing when confirmations are missed), resolving the contradiction through time-based verification.
2Loss of energy
If proxy processing is interrupted early, then resource consumption is reduced, but service availability may be compromised
Solution Approach 1:
The confirmation message mechanism provides continuous feedback about the proxy client's status, allowing the proxy apparatus to make informed decisions about continuing or interrupting proxy processing. This ensures that service availability is maintained as long as the client remains communicable, while resource consumption is reduced when the client is no longer reachable.
Solution Approach 2:
The patent establishes an active period duration parameter that defines in advance how long the proxy apparatus should continue processing without receiving confirmations before interrupting. This preliminary action sets a threshold that balances resource conservation with service availability, allowing the system to tolerate temporary communication issues while ultimately preventing resource wastage.
3Measurement precision
If confirmation messages are frequently exchanged, then client existence is accurately verified, but communication overhead increases
Solution Approach 1:
The patent implements confirmation messages at periodic intervals rather than continuously, which maintains adequate verification precision while significantly reducing communication overhead. The period is configured to balance between detecting client status changes timely and minimizing the frequency of communication exchanges.
Solution Approach 2:
The system uses a moderate level of confirmation messaging that is sufficient to verify client existence without being excessive. The confirmation frequency and active period duration are tuned to provide adequate verification precision while keeping communication overhead at acceptable levels, avoiding both under-verification and over-communication.
Data Source
AI summary
A proxy apparatus capable of executing proxy processing of at least one of transmission of information of a service provided by a communication apparatus and a search for a service provided by another apparatus for the communication apparatus accepts, from the communication apparatus, a request for execution of a proxy processing, based on communication complying with a NAN (Neighbor Awareness Networking) standard, executes the proxy processing for the communication apparatus based on the request, and confirms, during the active period, based on the communication complying with the NAN standard, whether the communication apparatus can communicate with the proxy apparatus while the proxy apparatus is executing the proxy processing.
