Solution Overview
Problem
Existing methods for switching connection between a terminal unit and a communication network, such as in PUSH services, often result in temporary network interruptions due to physical disconnection and reconnection, which degrade service quality.
Innovation Solution

1Speed
If a USB bus switch is used to selectively connect the communication device to either the terminal unit main body or the remote-controlled communication device, then the transmission speed is maintained when the terminal unit is in power-on state, but the network connection is temporarily interrupted during switching operations
Solution Approach 1:
The patent applies preliminary action by having the remote-controlled communication device write communication setting information to the terminal unit main body's memory before the switching operation occurs. This pre-preparation of connection parameters ensures that when the USB bus switch redirects the communication device to the terminal unit main body, the connection can be immediately established using the pre-loaded settings, thus maintaining network continuity while switching between power-off and power-on states.
Solution Approach 2:
The patent uses the terminal unit main body's memory as an intermediary to store and transfer communication setting information between the remote-controlled communication device and the network. This intermediary storage mechanism allows the communication settings to be preserved and quickly retrieved during switching operations, preventing network interruption while enabling the USB bus switch to change connection destinations.
2Use of energy by moving object
If the remote-controlled communication device operates independently at low clock rate to enable always-on connection, then power consumption is reduced, but data transmission rate is insufficient when terminal unit main body needs to perform processes
Solution Approach 1:
The patent applies dynamics by implementing a dynamic switching mechanism that changes the operational state of the terminal unit main body based on real-time needs. When data transmission is required and the terminal unit is in power-on state, the system switches connection from the remote-controlled communication device to the terminal unit main body, which operates at full processing capability. This dynamic adaptation allows the system to maintain low power consumption during idle periods while ensuring high data transmission rate when needed.
Solution Approach 2:
The patent implements multi-functionality by designing a system where the terminal unit main body can serve dual purposes: it can operate the communication device directly when high performance is needed, or allow the remote-controlled communication device to handle connections when power saving is the priority. The USB bus switch enables this universal functionality by routing the communication device to whichever component is currently the most appropriate host, making the system adaptable to different operational requirements.
Data Source
AI summary
An apparatus includes first and second processors, a common memory, and a switch. The first processor executes an operating system, connects to a communication network and communicates with the communication network. The second processor operates independently of the operating system, connects to the communication network, and communicates with the communication network. The second processor writes, in the common memory, communication setting information being used by the second processor when the switch switches the connection destination from the second processor to the first processor. The first processor acquires the communication setting information, and sets the acquired communication setting information to the first processor. The switch switches the connection destination of the communication network from the second processor to the first processor after the communication setting information has been set to the first processor.
