ZigBee Headset Reconnection via Pre-Transmitted Channel Info
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In ZigBee network systems, headsets experience prolonged reconnection times when switching channels, leading to inconvenience and delayed multimedia data reproduction due to the need to access and re-authenticate with multiple Personal Area Networks (PANs) after a mobile communication terminal changes its connection.
Innovation Solution
A method where the mobile communication terminal monitors and selects a new PAN, generates and transmits channel information to the headset, allowing the headset to directly access the new PAN and reconnect with the mobile communication terminal without scanning all channels, thereby reducing reconnection time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the headset accesses all channels and PANs to check mobile communication terminal access after connection disconnection, then the headset can reliably reconnection, but the reconnection time is significantly increased
Solution Approach 1:
The mobile communication terminal performs preliminary actions by monitoring available channels and PANs before disconnecting from the old PAN. It stores this channel information and proactively transmits it to the headset before the actual disconnection occurs. This allows the headset to have advance knowledge of which channels to monitor, eliminating the need to scan all channels after disconnection and significantly reducing reconnection time while maintaining reliability.
2Measurement precision
If the headset scans all 16 ZigBee channels to find the mobile communication terminal, then the headset can ensure it finds the correct PAN, but the multimedia data reproduction is delayed
Solution Approach 1:
The mobile communication terminal performs preliminary channel monitoring and identifies the target PAN before disconnection. It then transmits this pre-identified channel information to the headset, allowing the headset to jump directly to the correct channel instead of scanning all 16 channels sequentially. This maintains accurate PAN identification while dramatically improving multimedia data reproduction speed.
3Adaptability or versatility
If the mobile communication terminal closes connection with old PAN to join new PAN, then the terminal can access new content data, but the headset connection is automatically disconnected
Solution Approach 1:
Before the mobile communication terminal disconnects from the old PAN to join a new one, it performs preliminary monitoring of available channels and stores the target PAN's channel information. It then transmits this information to the headset in advance, enabling the headset to prepare for reconnection on the correct channel without manual intervention, thus maintaining ease of operation during PAN switching.
Solution Approach 2:
The channel information acts as an intermediary that bridges the disconnection event and the reconnection process. By transmitting this intermediate information to the headset before disconnection, the system enables automatic reconnection without requiring the headset to perform complex channel scanning or user intervention, simplifying the overall PAN switching operation.

AI summary
A peripheral device can reduce its reconnection time to a mobile communication terminal in a short-range personal wireless communication system including the peripheral device and the mobile communication terminal that performs short-range wireless communication. A short-range communication method of a node in a short-range personal wireless communication system in which communication is performed between at least one Personal Area Network (PAN) and multiple nodes. The method includes monitoring a peripheral PAN to perform short-range communication, and selecting at least one PAN as a result of the monitoring; generating channel information for the selected PAN; and transmitting the generated channel information to a peripheral device connected to the node, and connecting with the selected PAN.
