Electronic Device Paging Message Service Type Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, user equipment (UE) faces challenges in identifying the appropriate service (e.g., eMBB, mMTC, URLLC, or V2X) to use for communication services, leading to increased latency due to delays in activating the necessary components after receiving user data.
Innovation Solution
An electronic device identifies the predetermined service using an indicator included in a paging message, which triggers the application processor to increase its drive frequency, thereby reducing the time spent on user data processing and latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the UE waits to receive user data before identifying the communication service, then the service identification is accurate, but the latency increases due to delay in activating components
Solution Approach 1:
The patent applies preliminary action by including service type indicators in paging messages before user data transmission. The UE identifies the communication service type (eMBB, mMTC, URLLC, or V2X) in advance through the paging message indicator, allowing the application processor to be activated with the appropriate service configuration before actual user data arrives. This eliminates the delay that would otherwise occur after user data reception, while maintaining accurate service identification through the pre-configured indicator.
2Productivity
If the application processor is activated after receiving user data, then power consumption is reduced, but data processing time increases
Solution Approach 1:
The patent applies preliminary action by activating the application processor in advance based on the service type indicator received in the paging message, rather than waiting for user data arrival. This allows the processor to be ready with appropriate service configurations loaded, significantly reducing data processing time for latency-sensitive services like URLLC and V2X. The processor remains in a low-power state until the paging message triggers activation, balancing power efficiency with processing speed.
3Device complexity
If the UE uses a simplified service identification method, then processing complexity is reduced, but service type accuracy may be compromised
Solution Approach 1:
The patent introduces an intermediary element - a service type indicator field within the paging message structure - that carries explicit service type information (eMBB, mMTC, URLLC, V2X) from the network to the UE. This intermediary mechanism provides accurate service identification without requiring complex analysis of user data content or multiple measurement steps. The indicator acts as a direct pointer to the service type, simplifying the UE's identification process while ensuring precision through network-provided authoritative information.

AI summary
Provided are an electronic device and an operation method thereof. The electronic device may include: at least one communication processor configured to perform transmission and/or reception of a packet with a master node via cellular communication; and an application processor, wherein the at least one communication processor may be configured to control the electronic device to: receive, from the master node, a paging message including an indicator indicating a service type for transmission and/or reception of the packet; and activate the application processor based on performing a radio resource connection (RRC) connection with the master node, in response to identifying that the service type included in the indicator corresponds to a predetermined service type.
