Switching method, network element, gateway, base station, framework, apparatus, and storage medium

A gateway switching method, comprising:

• receiving, by a distributed gateway, a User Equipment (UE) Internet Protocol (IP) address of UE, which is assigned by a control plane network element based on a switch request;
• establishing, by the distributed gateway, an uplink tunnel;
• and
• storing, by the distributed gateway, a correspondence between an uplink tunnel identifier and the UE IP address, wherein the uplink tunnel identifier is a communication identifier of the uplink tunnel.

A gateway switching method, comprising:

• receiving, by a base station, downlink tunnel information sent from a control plane network element, wherein the downlink tunnel information comprises at least a User Equipment (UE) Internet Protocol (IP) address of UE, an uplink tunnel identifier, and a user plane IP address of a target distributed gateway that are assigned by the control plane network element;
• establishing, by the base station, a downlink tunnel;
• sending, by the base station, the UE IP address to the UE, and establishing a wireless connection with the UE;
• and
• establishing, by the base station, a correspondence between a downlink tunnel identifier, the uplink tunnel identifier, and the user plane IP address, wherein the downlink tunnel identifier is a communication identifier of the downlink tunnel.
