AI Technical Summary

Technical Problem

In 5G communication system, how to select the appropriate UPF network element to establish an efficient data channel between the access network device and the SF network element, ensure the connection relationship and shorten the transmission distance, and reduce the transmission time of perceived data.

Method used

The UPF network element that is close to the SF network element or has a data network connection relationship is selected by selecting the UPF network element based on the IP address, service area and data network connection identifier of the SF network element, and a first data channel is established to achieve efficient transmission of perceived data.

Benefits of technology

Ensure that there is a connection relationship between the UPF network element and the SF network element, shorten the transmission distance of the first data channel, reduce the transmission time of perceived data, and effectively reduce the number of signaling round trips between the access network equipment and the SF network element.

Abstract

The invention provides a data channel establishment method and device and a storage medium. In the method, the UPF network element which is closer to the SF network element or has the data network connection relationship with the SF network element can be selected based on the IP address, the service area and the data network connection identifier of the SF network element, so that the first data channel between the access network equipment and the SF network element is established through the UPF network element; the UPF network element and the SF network element are ensured to have a connection relationship, the transmission distance of the first data channel is shortened, and the transmission duration of the sensing data is reduced.
