Problems solved by technology

[0004] However, in the prior art, in order to realize the automatic allocation function of IPv6 addresses, it is necessary for the SMF to respond to the NS message and the RS message sent by the UE, and then the SMF forwards the NA message and the RA message to the UE through the UPF, resulting in the breakdown of the entire IPv6 address automatic allocation process. High processing delay

Abstract

The embodiment of the present application discloses a data transmission method, a user plane network element and a control plane network element, which can effectively reduce the processing delay of the automatic address assignment process and reduce the amount of data interacted between the user plane network element and the control plane network element . The method in the embodiment of the present application includes: the user plane network element receives the IPv6 address prefix information corresponding to the user equipment UE sent by the control plane network element; if the user plane network element receives the target request message sent by the UE, the user plane The network element generates a target response message carrying the IPv6 address prefix information and sends the target response message to the UE, the target request message includes a route request RS message, and the target response message includes a route advertisement RA message.

Description

technical field [0001] The present application relates to the communication field, in particular to a data transmission method, a user plane network element and a control plane network element. Background technique [0002] The 5G network architecture has readjusted the network architecture of the next-generation core network equipment. Usually, the 5G core network control plane (next generation control plane, NG-CP) will provide related functions externally through service interfaces. The session management function entity (session management function, SMF) of the NG-CP and the user plane function entity (userplane function, UPF) perform message interaction through the N4 or Sx interface, realizing the control plane (control plane, CP) to the user plane ( user plane (UP) user policy delivery and event reporting and processing from UP to CP. [0003] In the current automatic address assignment process of Internet protocol version 6 (IPv6), user equipment (user equipment, UE...
