Description

Technical Field

[0002] In the wave of development of new-generation information technology, edge-cloud collaboration, as an advanced distributed computing architecture, has shown great potential in complex computing tasks such as AI model training. This architecture, through the cooperation of the user interface (UE), radio access network (RAN), and cloud, can efficiently complete specific computing tasks. Offloading tasks from the edge to the cloud can significantly reduce system latency and energy consumption, and improve resource utilization and network efficiency.

[0003] Currently, the 3GPP standards framework has not yet conducted standardization research on edge-cloud collaborative scenarios. Existing computing task interaction modes primarily involve direct interaction between the terminal and the onboard computing platform. The network side cannot perceive the specific details of the computing task, making it difficult to rationally allocate network computing resources for joint computing based on the characteristics of specific scenarios and computing tasks. In reality, the terminal (UE), radio access network (RAN), and cloud all possess certain computing resources. How to achieve collaborative computing task allocation for edge-cloud scenarios in space-air-ground scenarios is a pressing technical problem that needs to be solved in this field.
