AI Technical Summary

Technical Problem

Existing technologies lack a solution for establishing and modifying connections among multiple user planes in a dual-connectivity mobile communication system, specifically in configuring redundant protocol data unit (PDU) sessions.

Method used

A method and device for configuring redundant PDU sessions by obtaining redundancy indication information and configuring redundant PDU sessions or quality of service (QoS) flows on corresponding Radio Access Network (RAN) nodes, allowing for the establishment and modification of connections among multiple user planes.

Benefits of technology

Enables efficient establishment and modification of user plane multi-connectivity by configuring redundant PDU sessions and QoS flows on specific RAN nodes, enhancing network connectivity and flexibility.

Abstract

The invention provides a method and a device for configuring a redundant PDU session. The method includes: obtaining first redundancy indication information for establishing or modifying the PDU session and / or a QoS flow; and configuring the redundant PDU session and / or a redundant QoS flow on a corresponding RAN node, according to the first redundancy indication information. In the present invention, establishing and modifying of a user plane multi-connectivity can be realized by obtaining the redundancy indication information for establishing or modifying the PDU session and / or the QoS flow, and configuring the redundant PDU session and / or the QoS flow to the corresponding RAN node according to the redundancy indication information.
