Embodiments of the present invention provide a method, network element and system for deleting a user plane tunnel, and relate to the technical field of communication. The method is applied in a communication system. The communication system includes a control plane network element and a user plane network element. There is at least one user plane tunnel between the control plane network element and the user plane network element. The method includes: the control plane network element determines There is a target user plane tunnel that meets the preset conditions in at least one user plane tunnel; the control plane network element sends a request message to the user plane network element, and the request message is used to instruct the user plane network element to delete the target user plane tunnel; the user plane network element Delete the target user plane tunnel according to the request message. In the solution of the embodiment of the present invention, for the scenario where the control plane and the user plane are separated, a technical solution is provided to delete the user plane tunnel between the control plane network element and the user plane network element, so that the user plane tunnel can be used when it is not needed to save resources.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method, network element and system for deleting a user plane tunnel. Background technique [0002] Control and User Plane Separation (CUPS) is a development trend of the core network network architecture. The functions of the control plane (Control Plane, CP) and the user plane (User Plane, UP) are performed by different functional entities, so that the control plane and the user plane can use different software or hardware resources and be deployed to different locations according to requirements , to achieve higher flexibility. [0003] Taking the core network of the fourth generation (4th Generation, 4G) system as an example, the third generation partnership project (the3rd Generation Partnership Project, 3GPP) proposes to integrate the serving gateway (Serving Gateway, SGW) and packet data gateway (Packet Data Network Gateway , PDN-GW or PGW) are divided into a con...
