Communication Apparatus Search Timing Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, a base station cannot efficiently detect other communication apparatuses with desired services due to timing issues with the search process, particularly when devices have not yet joined the network, leading to delayed detection and impaired user convenience.
Innovation Solution
A communication apparatus is designed with control means to create a network, assignment means to provide necessary communication information, and search means to detect specific service functions, where the search process starts only after the assignment of information is complete, ensuring timely detection of available services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the communication apparatus transmits a search message immediately after the network is created, then the search process starts quickly, but the other communication apparatus has not joined the network yet and cannot respond
Solution Approach 1:
The patent applies preliminary action by having the base station wait for the DHCP assignment process to complete before initiating the service search. The control unit is configured to start the search process only after confirming that IP address assignment has been completed, ensuring that all client devices have properly joined the network and are ready to respond to search messages.
2Reliability
If the communication apparatus waits for a long time after network creation before transmitting search message, then the other communication apparatus has joined the network, but the detection time is delayed
Solution Approach 1:
The patent implements feedback by using the DHCP assignment completion status as a trigger signal for initiating the service search. The control unit monitors the assignment process and uses its completion as feedback to determine the optimal timing for starting the search, ensuring both network readiness and timely detection without unnecessary delays.
3Adaptability or versatility
If the communication apparatus transmits search message at any time, then the search process can be initiated flexibly, but unnecessary search messages are transmitted when devices are not ready
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the search initiation timing based on the network state. The control unit changes the search process state from unavailable to available only after the DHCP assignment parameter is completed, optimizing the balance between search flexibility and energy efficiency by avoiding unnecessary transmissions during inappropriate timing.
Data Source
AI summary
A communication apparatus creates a network, assigns information necessary for performing communication in the created network to each of other communication apparatuses which have joined the network, and searches for a communication apparatus having a specific service function. Upon completion of assignment of the information necessary for performing communication in the created network, the communication apparatus starts the search.
