Multi-SIM UE Paging Priority for Shared TX/RX Service Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-SIM user equipment (UE) communication, the need arises to manage paging messages effectively to avoid interruptions in ongoing services when a UE receives a paging message from one network while communicating with another, as sharing a common TX/RX chain can lead to service disruptions.
Innovation Solution
Incorporating service priority information in paging messages allows the UE to determine the priority of the incoming transmission, enabling it to decide whether to respond or ignore the message, thereby managing resource allocation and service continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the UE shares a common TX/RX chain between multiple SIMs, then device complexity is reduced, but service disruptions occur when paging messages interrupt ongoing communications
Solution Approach 1:
The system dynamically adjusts the UE's response behavior to paging messages based on the current service state and priority level. The UE can transition between different operational modes (responding to paging vs. maintaining ongoing service) based on real-time conditions, making the system adaptable rather than static.
Solution Approach 2:
The patent introduces service priority information as a new parameter in paging messages that changes the decision-making criteria for responding to pages. By adding this parameter, the system transforms the binary respond/don't respond decision into a priority-based selective response mechanism.
2Speed
If the UE responds to all paging messages, then service responsiveness is improved, but service disruptions increase due to interruptions in ongoing communications
Solution Approach 1:
Different paging messages receive different treatment based on their specific priority level. High-priority paging messages trigger immediate response while low-priority messages are deferred or ignored, creating localized quality differences in response behavior rather than uniform treatment of all pages.
Solution Approach 2:
The system uses service priority information as feedback from the network to guide the UE's response behavior. The UE continuously monitors the priority level of incoming paging messages and adjusts its actions accordingly, creating a feedback loop between network indications and device behavior.
3Reliability
If the UE ignores low-priority paging messages, then service continuity is maintained, but resource allocation efficiency decreases
Solution Approach 1:
The UE autonomously determines whether to respond to paging messages based on the service priority information contained in the messages themselves and its current operational state. This self-service mechanism eliminates the need for continuous network control signals, allowing the device to independently optimize its resource allocation decisions.
4Reliability
If the UE establishes connections for all paging messages, then information transmission reliability is improved, but resource utilization deteriorates due to frequent connection establishment
Solution Approach 1:
Instead of fully responding to all paging messages, the UE applies partial action by selectively responding only to high-priority messages while ignoring or deferring low-priority ones. This partial response strategy maintains essential service reliability while reducing the excessive resource consumption associated with full response to every page.

AI summary
Certain aspects of the present disclosure provide techniques for service priority information for multi-SIM user equipment (UE) paging. An exemplary method generally includes communicating with a first network using a first set of credentials, wherein the UE includes a second set of credentials associated with a second network; receiving a paging message for an information transmission in the second network, wherein the paging message includes service priority information corresponding to the information transmission; determining, from the service priority information, a service priority value corresponding to the information transmission based, at least in part, on policy configuration information; determining whether to establish a connection in the second network in response to the paging message based, at least in part, on the service priority value; and taking one or more actions based, at least in part, on the determination.
