Common Paging Occasion for Multi-Subscription Device Wake-Up
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Paging multiple devices with separate subscriptions requires them to wake up multiple times during separate paging occasions, which is not desirable for power saving.
Innovation Solution
Paging multiple devices using a common paging occasion by allocating a paging reference identifier that is associated with all devices, allowing them to wake up once to receive messages intended for multiple subscriptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple devices use separate paging occasions for paging, then each device can be paged independently, but devices need to wake up multiple times which increases power consumption
Solution Approach 1:
The patent merges multiple separate paging occasions into a single common paging occasion where multiple devices with different subscriptions can be paged simultaneously. The core network associates multiple subscriptions with a common paging reference identifier, allowing the base station to page multiple devices in one occasion, thereby reducing the number of wake-up events and power consumption while maintaining reliable paging delivery to all devices.
Solution Approach 2:
The patent creates a universal paging mechanism where a single paging occasion serves multiple devices with different subscriptions. The common paging reference identifier acts as a universal key that links multiple subscriptions to one paging event, enabling the paging system to handle multiple devices through a unified process rather than separate individual paging occasions.
2Reliability
If multiple devices wake up multiple times for separate paging occasions, then each device receives its paging messages reliably, but power efficiency decreases
Solution Approach 1:
The patent combines multiple paging events into a single common paging occasion, reducing the frequency of wake-up events from multiple times to once per common paging occasion. This merging approach maintains reliable message delivery to all devices while significantly improving power efficiency by minimizing the energy expended on repeated wake-up cycles.
Solution Approach 2:
The patent establishes a periodic common paging occasion that occurs at regular intervals, during which all devices with associated subscriptions are paged simultaneously. This periodic structure allows devices to remain in low-power states between occasions and only wake up at the predetermined common paging time, optimizing power efficiency while ensuring reliable periodic message delivery.

AI summary
Aspects of the disclosure relate to paging multiple subscription devices during a common paging occasion. In an aspect, a core network device may perform a first network registration with a first wireless device using a first subscription, wherein performing the first network registration includes associating a paging reference identifier with the first subscription. The core network device perform a second network registration with a second wireless device using a second subscription, wherein performing the second network registration includes associating the paging reference identifier further with the second subscription. The core network device may further request a base station to page the first wireless device and the second wireless device during a paging occasion based on the paging reference identifier.
