Wireless Device Paging Disable via Relay Node
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication devices (WCDs) may lose coverage, leading to failed paging attempts by the Radio Access Network (RAN), which wastes resources as the RAN is unaware of the loss of coverage and continues to attempt to page the device.
Innovation Solution
A first WCD, out of coverage, uses a second WCD in coverage to relay a message to the RAN to disable paging, allowing the RAN to conserve resources by removing the WCD's entry from the Visitor Location Register.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the RAN continues to page a WCD that has lost coverage, then the RAN can ensure it does not miss any incoming calls for the WCD, but the RAN wastes processing power, data storage capacity, and wireless network capacity on futile paging attempts
Solution Approach 1:
The system implements feedback by having the WCD actively report its coverage status to the RAN. When a WCD detects it has lost coverage, it sends a coverage status report message to the RAN, which then updates its paging behavior accordingly. This feedback loop allows the RAN to adjust its paging strategy based on real-time WCD status information.
Solution Approach 2:
The system performs preliminary action by having the WCD proactively report its coverage status before the RAN attempts paging. The WCD monitors its own coverage status and sends advance notification to the RAN, allowing the RAN to prevent futile paging attempts before they occur rather than reacting after paging failures are detected.
2Productivity
If the RAN disables paging to a WCD that has lost coverage, then the RAN conserves processing power, data storage, and wireless network capacity, but the RAN may miss incoming calls if the WCD actually regains coverage
Solution Approach 1:
The system implements dynamic paging behavior where the RAN adjusts its paging strategy based on the WCD's reported coverage status. When a WCD reports lost coverage, the RAN disables paging to that WCD. When the WCD later reports regained coverage, the RAN re-enables paging. This dynamic adaptation allows the system to optimize resource usage while maintaining reliability when needed.
Solution Approach 2:
The system uses continuous feedback from the WCD about its coverage status to dynamically adjust RAN paging behavior. The WCD sends coverage status reports that trigger corresponding changes in RAN paging configuration, allowing the system to respond to changing conditions and maintain optimal performance.
3Ease of operation
If the WCD uses a second wireless communication technology to relay a message to the RAN via another WCD, then the out-of-coverage WCD can inform the RAN of its status, but the system requires additional communication protocols and device capabilities
Solution Approach 1:
The system applies multi-functionality by enabling WCDs to perform multiple roles: they can communicate with the RAN using the first wireless communication technology and also relay messages for other WCDs using the second wireless communication technology. This universal capability allows any WCD in coverage to act as a relay node, distributing the reporting function across the network rather than requiring dedicated infrastructure.
Solution Approach 2:
The system uses an intermediary approach where a second WCD that is in coverage acts as a mediator to relay the coverage status report from a first WCD that is out of coverage to the RAN. This intermediary mechanism allows out-of-coverage devices to communicate their status without requiring direct communication paths to the RAN.

AI summary
Methods and systems for disabling paging to a WCD that fails to communicate properly with a RAN are introduced. In an exemplary embodiment, a first WCD that fails to communicate properly with the RAN may inform the RAN of the failure to communicate by relaying a message to the RAN via a second WCD. The second WCD preferably is able to communicate properly with the RAN. Upon receiving the message from the second WCD, the RAN may disable paging to the first WCD, thereby helping to conserve data storage, processing cycles, and paging channel capacity at the RAN.
