AI Technical Summary
Technical Problem
In the satellite return scenario of the base station of the 3GPP network, the dynamic changes in the return method cause the data packets received by the receiving end to be out of order, affecting the normal progress of the service.
Method used
The network-side device sends a satellite back-relay notification message to the application function entity. The application function entity determines whether the network-side device realizes the orderly delivery of data packets by the network-side device.
Benefits of technology
It realizes the orderly delivery of data packets in satellite dynamic return scenarios, ensures the order of service data, and improves the reliability and service quality of services.

Abstract
The present disclosure relates to a method and system for sequential data delivery, a network side device and an application function entity. The method for sequential data delivery includes: the application function entity receives a satellite return mode notification message, wherein the network side device sends a satellite return mode notification message to the application function entity when the base station to which the current service is accessed adopts a satellite dynamic return mode; the application function entity determines whether the network side device implements sequential data delivery according to service requirements and service capabilities when the satellite return mode is a satellite dynamic return mode; when it is determined that the network side device implements sequential data delivery, the application function entity requests the network side device to perform sequential data packet delivery on the service data packet. The network side device of the present disclosure can perform sequential data packet delivery processing according to the requirements of external applications.
