Communication Terminal Suspend Control for Network Keep-Alive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication terminals face issues with unnecessary disconnection of online communications due to suspend operations, leading to inconvenience and discomfort for users, as current techniques disconnect network connections without maintaining a keep-alive state.
Innovation Solution
A communication terminal with application control means, communication control means, and suspension control means that allows for selecting a keep-alive state during suspend operations, maintaining communication connections without disconnecting from the network, and resumes operations smoothly by transmitting suspend and resume commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the application is suspended by disconnecting network connection, then the suspend operation is effective and resource usage is reduced, but communication disconnection occurs and user convenience deteriorates
Solution Approach 1:
The patent segments the suspension operation into two independent parts: application suspension and network connection maintenance. The suspension control unit suspends the application while the communication control unit maintains the network connection, allowing each to function independently without forcing a trade-off between them.
Solution Approach 2:
The patent performs preliminary action by maintaining the network connection in advance before the application is fully suspended. By keeping the communication connection active during application suspension, the system prepares for quick resumption without requiring reconnection procedures.
2Ease of operation
If the application is suspended with network connection maintained, then communication continuity is preserved, but system resource usage increases
Solution Approach 1:
The patent applies local quality by maintaining network connection only for applications that require communication continuity, rather than universally maintaining all connections. The suspension control unit determines on a per-application basis whether to maintain the connection, optimizing resource usage selectively.
3Reliability
If reconnection operation is performed after suspend disconnection, then communication is restored, but time is lost and productivity decreases
Solution Approach 1:
The patent ensures continuity of useful action by maintaining the network connection active during application suspension. The communication control unit keeps the connection established, allowing the application to resume communication immediately without interruption or reconnection delay.

AI summary
A communication terminal includes: an application control unit that controls execution of an application; a communication control unit that controls a communication unit to establish communication with a communication network, and a suspension control unit that, after detecting a terminal operation that becomes a factor in suspending the application, transmits a suspend command to suspend the application that is running to the application control unit. The suspension control unit is, in response to the terminal operation thus detected, capable of selecting a keep-alive state for transmitting the suspend command to the application control unit without disconnecting communication connection with the communication network by the communication unit. The communication terminal prevents unnecessary disconnection of communication by a suspend operation and improving convenience and comfortableness of application operation.
