Portable Terminal Network Status Detection via Bearer Connection Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable terminals experience increased battery consumption due to frequent heartbeat or ping message transmissions, which are necessary to maintain network connection status, leading to reduced operational time.
Innovation Solution
The solution involves reconfiguring the data packet transmission time to coincide with bearer connection events, such as Location Area Updates (LAU) or Routing Area Updates (RAU), thereby reducing the number of bearer connections and minimizing battery drain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the portable terminal periodically transmits heartbeat or ping messages to maintain network connection status, then the network connection status can be maintained and reported, but battery consumption increases and operational time decreases
Solution Approach 1:
The patent combines the heartbeat message transmission with the bearer connection establishment for Location Area Update (LAU) or Routing Area Update (RAU). Instead of separately transmitting heartbeat messages at scheduled intervals, the terminal merges these transmissions with necessary bearer connections, thereby reducing the total number of separate transmissions and associated battery consumption while maintaining network connectivity status reporting
2Loss of information
If the portable terminal transmits heartbeat messages at scheduled intervals, then the server can accurately track terminal availability, but the number of bearer connections increases and battery consumption increases
Solution Approach 1:
The patent utilizes preliminary actions by leveraging necessary bearer connections (LAU/RAU) that must be established regardless. By piggybacking heartbeat transmissions on these pre-planned connections, the system ensures server awareness of terminal availability without adding extra dedicated heartbeat transmissions, thereby preserving information while extending operational time
Data Source
AI summary
An apparatus and method for decreasing the number of bearer connections by transmitting a data packet in order to determine a network connection status at a time of bearer connection necessarily performed by a portable terminal together with a location registration message. Reduced battery consumption in the portable terminal is achieved because of the reduced number of bearer connections. The apparatus includes a transmission time determination unit for reconfiguring a data packet transmission time to a time of bearer connection necessarily performed by the portable terminal when a data packet is transmitted to determine the network connection status, and a controller for providing control to transmit the data packet is transmitted while connecting the bearer at the reconfigured data packet transmission time, wherein the reconfigured data packet transmission time may be advanced or delayed of the initial transmission time.
