Document Type and Number:
WIPO Patent Application WO/2021/032216
Kind Code:
A1
Abstract:
Disclosed are a redundant session establishment method and apparatus, a radio bearer establishment method and apparatus, and nodes, a terminal and a medium. The redundant session establishment method comprises: generating redundant user plane resource information, and transmitting the redundant user plane resource information to a primary node; and on the basis of a redundant session request from the primary node, establishing a redundant session corresponding to the redundant session request in a redundant user plane resource, the redundant session request being a request generated by the primary node on the basis of the redundant user plane resource information.
