1. A redundant session establishment method, comprising:
generating redundant user plane resource information, and transmitting the redundant user plane resource information to a master node; and
establishing a redundant session corresponding to a redundant session request in a redundant user plane resource according to the redundant session request from the master node, wherein the redundant session request is a request generated by the master node according to the redundant user plane resource information;
wherein the redundant user plane resource refers to a user plane resource that establishes the redundant session, and the redundant user plane resource information refers to information generated according to the number of redundant user plane resources of a secondary node and is used for the secondary node to indicate the number of the redundant user plane resources of the secondary node to the master node;
wherein identification information of the redundant session is comprised in the redundant session request;
wherein in a case where the master node determines to establish at least two redundant sessions in the redundant user plane resource of the secondary node, the redundant session request further comprises a redundant serial number value of a redundant session;
wherein the establishing the redundant session corresponding to the redundant session request in the redundant user plane resource according to the redundant session request from the master node comprises:
establishing the redundant session corresponding to the redundant session request in a redundant user plane resource matched with the redundant serial number value of the redundant session according to the identification information of the redundant session in the redundant session request and the redundant serial number value of the redundant session.
