Solution Overview
Problem
In new radio (NR) systems, relay terminals struggle to effectively provide proximity computing services to remote terminals, as existing methods do not efficiently manage computing loads and optimize service computing and transmission efficiency.
Innovation Solution
A wireless communication method where a second terminal shares part of the computing tasks of a first terminal by using a sidelink between the two terminals, allowing the second terminal to unload work tasks of a proximity-based service, thereby reducing the computing load of the first terminal and optimizing service efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a relay terminal provides both communication service and computing service, then service functionality is improved, but device complexity increases
Solution Approach 1:
The patent segments the service functionality by establishing a separate PDU session specifically for proximity computing services. This allows the relay terminal to provide computing services through a dedicated communication pathway without complicating the primary communication service architecture, thus resolving the contradiction between enhanced functionality and device complexity.
2Productivity
If computing tasks are shared between terminals, then computing load is reduced, but transmission time increases
Solution Approach 1:
The patent applies preliminary action by establishing the PDU session for proximity computing services in advance before computing tasks need to be offloaded. This pre-configuration includes pre-establishing the necessary signaling and routing paths, so when computing tasks arise, they can be transmitted immediately without delays, thus reducing overall transmission time while enabling computing task sharing.
3Reliability
If a dedicated PDU session is established for proximity computing services, then service quality is improved, but signaling complexity increases
Solution Approach 1:
The patent makes the PDU session establishment mechanism universal by using the same signaling procedures and existing network infrastructure for both communication services and proximity computing services. The SMF entity handles both types of sessions using consistent protocols, which simplifies the signaling complexity while maintaining dedicated service quality through proper session isolation and resource allocation.
