Abstract

Embodiments of the present invention provide a communication method, a security node network element and a terminal. The method includes: a security node network element receives a first data packet from a terminal, the first data packet carries first user plane data or first control signaling, wherein the first data packet passes through the first secure connection or the second secure The first secure connection is used to transmit the first data packet carrying the first user plane data, and the second secure connection is used to transmit the first data packet carrying the first control signaling; if the When the first data packet is transmitted through the second security connection, the security node network element sends the first control signaling to the control plane functional entity. The embodiment of the present invention can solve the security problem existing in the transmission of the control signaling between the security node network element and the terminal in the existing solution.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a communication method, a security node network element, and a terminal. Background technique [0002] In the current communication network, when the network element of the security node receives the uplink data packet sent by the terminal, it needs to identify whether the uplink data packet carries control plane signaling. If the uplink data packet carries control signaling, the security node network element sends the control plane signaling to the control plane function (Control Plane Function, CP Function) entity; if the uplink data packet does not carry control signaling, the security node The node network element sends the user plane data in the uplink data packet to a user plane function (User Plane Function, UP Function) entity. [0003] In an existing solution, a data packet carrying control signaling can be identified by setting a destination Int...
