Problems solved by technology

On the other hand, in the process of terminal handover from 4G network to 5G network, the current 3GPP agreement does not define how the source (source) MME queries the target (target) AMF network element, so it is still impossible to truly realize the terminal from 4G network to 5G network. network switching

Abstract

The embodiment of the invention provides a switching method, device and system, which not only can simplify the switching process of a terminal, but also can realize the switching of the terminal froma 4G network to a 5G network. The switching method comprises: enabling a converged network device to receive a switching demand from a first access device in a first network, the switching demand carrying an identifier of a second access device in a second network or an identifier of a tracking area served by the second access device; determining that the second access device belongs to the jurisdiction of the converged network device according to the identifier of the second access device or the identifier of the tracking area served by the second access device; sending a switching request to the second access device, wherein the switching request is used for requesting the second access device to prepare related resources for the terminal; sending a switching command to the first accessdevice, wherein the switching command is used for indicating to switch the terminal to the second access device; and receiving a switching notification from the second access device, wherein the switching notification is used for indicating that the terminal has been switched to the second access device.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a handover method, device and system. Background technique [0002] Currently, the 3rd generation partnership project (3rd generation partnership project, 3GPP) technical standard (technical specification, TS) 23.501 defines the terminal in the fourth generation (4th generation, 4G) network and the fifth generation (5th generation, 5G) network The interoperability process in the network includes, for example, the process of handing over a terminal from a 5G network to a 4G network; or the process of handing over a terminal from a 4G network to a 5G network. [0003] Among them, in order to realize the intercommunication between 4G network and 5G network, in the intercommunication architecture of 4G network and 5G network currently discussed by the 3GPP standard group, the access and mobility management function (AMF) network element in the 5G network An N26 ...
