Relay UE Paging Transmission Information Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Device-to-Device (D2D) communication technologies face high network signaling overhead when calculating paging transmission information based on the IMSI of a relay UE, leading to increased power consumption and signaling requirements.
Innovation Solution
The base station acquires and uses two sets of paging transmission information, one for the relay UE and one for the remote UE, to send paging messages independently, eliminating the need to consider the connection state of either UE, thereby reducing network signaling overhead and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base station calculates paging transmission information according to the IMSI of the relay UE, then the paging message can be sent to the relay UE, but the network signaling overhead increases due to real-time connection status queries
Solution Approach 1:
The base station pre-calculates and stores multiple sets of paging transmission information corresponding to different connection states of the relay UE and remote UE. When paging is needed, the base station directly selects the appropriate pre-calculated information based on the current state without performing real-time calculations or queries, thereby reducing signaling overhead while ensuring reliable message delivery.
2Reliability
If the base station queries the connection status of relay UE and remote UE in real time, then the paging message can be accurately routed, but the power consumption of the relay UE increases
Solution Approach 1:
The system pre-calculates paging transmission information for various connection states before the relay UE needs to page the remote UE. The relay UE stores these pre-computed results and directly uses them when needed, avoiding real-time status queries and calculations that would consume power, while still achieving accurate routing.
Solution Approach 2:
The base station generates and stores multiple copies of paging transmission information corresponding to different connection states. Instead of querying the current state and calculating anew, the system retrieves the appropriate pre-generated copy, eliminating the need for real-time status verification and reducing power consumption at the relay UE.
3Adaptability or versatility
If the relay UE monitors multiple remote UEs, then the system supports multiple connections, but the complexity of determining paging transmission information increases
Solution Approach 1:
The paging transmission information is segmented into multiple independent sets, each corresponding to a specific connection state or remote UE. The relay UE can select and use the appropriate segment without processing all possible scenarios, thereby supporting multiple connections while maintaining simple determination logic for each individual case.
Solution Approach 2:
The pre-calculated paging transmission information structure is designed to be universal, covering multiple remote UEs and connection states within a unified framework. This allows the relay UE to handle multiple connections using the same selection mechanism, avoiding the need for complex individual processing for each remote UE.
