Data packet processing method, control plane network element, and user plane network element

摘要

A data packet processing method, a control plane network element, and a user plane network element are provided. The method comprises sending a first request message by a control plane network element to a user plane network element, wherein the first request message comprises a first request message between the control plane network element and the user plane network element. A first request message from the control plane network element, wherein the first request message is used to request to establish a user plane channel, the first request message including a control plane side endpoint identifier of the first user plane channel; Receiving a request message by a user plane network element and sending a first response message to the control plane network element based on the first request message, wherein the first response message comprises a first user Successful establishment of plain channel Sending, by the user plane network element, a first data packet to the control plane network element via the first user plane channel; and Receiving, via one user plane channel, a first data packet sent by the user plane network element. According to embodiments of the present invention, implementing establishment of a user plane channel between a user plane network element and a control plane network element, and data packets between the user plane network element and the control plane network element To facilitate sending.
