Communication Device Association Request Handshake Overhead Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the overhead caused by independent handshakes between communication devices and multiple network devices on the same channel leads to inefficient channel resource utilization.
Innovation Solution
A communication device transmits a plurality of association request messages to multiple network devices, each with a same broadcast (BC) address and acknowledgement (ACK) policy, and varying first ACK priorities, to reduce handshake overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If independent handshakes are performed with multiple network devices according to communication standard, then coordination of operating mode status is achieved, but overhead increases and channel resource utilization deteriorates
Solution Approach 1:
The patent merges multiple independent handshake processes into a single unified handshake operation. The communication device performs one handshake with the first network device that includes indication information about second network devices, allowing coordination with multiple network devices simultaneously rather than sequentially, thus reducing overhead while maintaining reliable coordination.
Solution Approach 2:
The handshake mechanism is enhanced to serve multiple functions simultaneously. The single handshake not only coordinates operating mode status with the first network device but also establishes connections and transmits data with multiple second network devices, making the handshake process multi-functional and reducing the need for separate coordination procedures.
2Reliability
If independent handshakes are performed with multiple network devices, then reliable connection establishment is achieved, but channel resource utilization deteriorates
Solution Approach 1:
Multiple connection establishment processes are merged into a single handshake operation. The indication information in the handshake message allows the communication device to establish connections with multiple network devices (both first and second network devices) simultaneously through one unified process, improving channel utilization while ensuring reliable connections.
3Loss of energy
If multiple association request messages are transmitted with varying ACK priorities, then handshake overhead is reduced, but message complexity increases
Solution Approach 1:
The patent applies local quality by introducing ACK priorities specifically for association request messages while keeping other message types unchanged. Different ACK priorities are assigned to different association request messages based on their importance, allowing selective acknowledgment handling that reduces overhead for less critical messages while maintaining reliability for important ones, without complicating the overall system beyond the specific message type.
