Outage Signaling for Wireless Call Continuity and Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in maintaining call continuity and managing service outages, particularly in environments with unreliable network coverage, leading to inefficient power consumption and communication disruptions.
Innovation Solution
User equipment (UE) and network units implement an outage indicator system, where the UE transmits an expected outage signal, initiating a timer that suspends communication during the outage period, and the network unit responds by refraining from communication during this timer duration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE continuously monitors and attempts to communicate during network outages, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The UE receives and processes an indicator from the network unit in advance that signals an upcoming service outage. This preliminary notification allows the UE to proactively suspend communication activities before the actual outage occurs, rather than continuously monitoring during the outage period. By acting on the indicator beforehand, the UE reduces power consumption while maintaining communication reliability through proper call continuity management.
2Reliability
If the network unit maintains communication attempts during expected outages, then call continuity is improved, but network resources are wasted
Solution Approach 1:
The network unit transmits an indicator to the UE that provides feedback about an expected service outage. This feedback mechanism allows the network to inform the UE of upcoming outages, enabling the UE to suspend communication appropriately. The feedback loop ensures that both the UE and network unit coordinate their communication behavior during outages, maintaining call continuity while avoiding waste of network resources through synchronized suspension of communication activities.
3Use of energy by moving object
If the UE suspends communication during expected outages, then power consumption is reduced, but communication disruptions may occur
Solution Approach 1:
The UE receives advance notification of an expected outage through the indicator and suspends communication in a coordinated manner. This preliminary action, combined with the network unit's simultaneous suspension of communication attempts, ensures that call continuity is maintained through proper coordination rather than uncoordinated suspension. The UE can resume communication immediately after the outage period, minimizing disruptions while achieving power savings during the outage window.

AI summary
Wireless communications systems, apparatuses, and methods are provided. A method of wireless communication performed by a user equipment (UE) includes transmitting, to a network unit, an indicator indicating an expected outage, starting an outage timer based on the indicator, and refraining from communicating for a duration of the outage timer.
