AI Technical Summary
In non-terrestrial networks with fast-moving access network devices, the target access network device struggles to find the anchor access network device to retrieve the context information of a terminal device, complicating the connection resume mechanism and impacting system performance.
A communication method where the first access network device sends context information and a security verification parameter to the core network device, enabling the second access network device to obtain the context information from the core network device, ensuring a successful connection resume and reducing mobility impacts.
This approach ensures a stable connection resume mechanism by allowing the second access network device to retrieve context information from the core network device, thereby improving system performance and reducing the impact of mobility on the connection resume procedure.
