AI Technical Summary

Technical Problem

In edge computing scenarios, especially in low Earth orbit satellite networks, the existing edge application server discovery process is not applicable, making it difficult for terminals to select suitable edge application servers or offloading points, thus affecting the normality of service transmission.

Method used

By acquiring service deployment information, including time information, non-terrestrial network device identifiers, or data network access identifiers, control plane network elements are used to select appropriate edge application servers or distribution points to ensure normal service transmission.

Benefits of technology

It enables the selection of appropriate edge application servers or offloading points within the low Earth orbit satellite network, ensuring normal service transmission and improving user experience.

Abstract

The communication method and device can be applied to non-terrestrial network (NTN) communication, and can select a suitable edge application server (EAS) and a distribution point for a terminal in a scenario where an EAS / user plane network element (UPF) is deployed on a satellite, thereby ensuring transmission of service data and improving user experience. The method comprises the following steps: a control plane network element (such as a session management network element) can obtain information of a first user plane network element according to information of a first service and service deployment information, and then send the information of the first user plane network element to determine an EAS, or configure the first user plane network element according to the information of the first user plane network element, wherein the EAS or the first user plane network element is used for terminal access to the first service. The service deployment information comprises at least one of the following: time information corresponding to service information, non-terrestrial network device identification corresponding to the service information, or data network access identification corresponding to the service, wherein the data network access identification corresponds to the non-terrestrial network device.
