Wireless Session Suspension for Positional Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication protocols require repeating parameter determination when starting a new session to determine positional relationships between electronic devices, which is time-consuming and inefficient.
Innovation Solution
Temporarily suspending a current wireless communication session and resuming it without repeating parameter determination by withholding scheduled signals and using pre-determined parameters in a new set of wireless signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a new session is started after stopping a partially-conducted session, then the positional relationship determination can be重新开始, but parameter determination must be repeated which consumes time
Solution Approach 1:
The patent applies preliminary action by determining parameters in advance during the initial session setup, storing them for later use when the session is resumed. This allows the system to skip repetitive parameter determination when restarting a session, directly resolving the time loss issue while maintaining session reliability
Solution Approach 2:
The patent recovers previously determined parameters by storing them during the initial session and reusing them when the session is resumed. Instead of discarding these parameters when the session stops, the system retrieves and reuses them, eliminating the need for repeated parameter determination and reducing time consumption
2Loss of information
If parameter determination is repeated in a new session, then complete parameter exchange is ensured, but the procedure becomes time-consuming and inefficient
Solution Approach 1:
The patent recovers previously exchanged parameter information by storing it during the initial session and retrieving it when resuming. This ensures parameter exchange completeness is maintained without requiring repetitive exchange, thereby improving determination efficiency
Solution Approach 2:
The patent maintains continuity of useful action by keeping the session state active through suspension rather than fully terminating it. The parameter determination process is paused but not restarted, allowing the useful action of parameter exchange to continue from where it left off without repetition, thus improving efficiency while ensuring completeness

AI summary
In a procedure for determining distance (or angle) between a pair of electronic devices wirelessly connected to one another, a current session may be temporarily suspended on request and thereafter the current session may be resumed. Temporary suspension and resumption of the current session may, for example, eliminate starting a new session between the pair of electronic devices and repeating a determination of parameters that were initially agreed upon in the current session. Temporary suspension of a current session may be signaled wirelessly, by one electronic device to the other electronic device, for example, by setting a specific value in a specific field, to signal that the current session is to be paused now, in a frame or message transmitted from the pausing device to the to-be-paused device. The current session may be resumed without repeating determination of the initially-agreed upon parameters, by transmitting a frame to initiate measurement exchange.
