Embodiment Construction

[0097] In order to make the purpose, technical solution and advantages of the present disclosure clearer, the implementation manners of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.

[0098] Before explaining the data sending method provided by the embodiment of the present disclosure in detail, the network structure of the 5G network is firstly introduced.

[0099] Such as figure 2 As shown, the network structure mainly includes the following network entities: UE, RAN, UPF, DN, AMF, SMF, access authentication function (Authentication Server Function, AUSF), network capability exposure function (Network Exposure Function, NEF), Network function discovery function (NF Repository Function, NRF), policy control function (Policy Control function, PCF), unified data management function (Unified Data Management, UDM), application layer interface function (Application Function, AF).

[0100] Among them, UE can be a m...

Abstract

The disclosure provides a data sending method, device and equipment, which belong to the technical field of communication. The method includes: receiving an uplink data packet sent by the UE; if the uplink data packet carries a signaling message, stripping the signaling message from the uplink data packet, and the signaling message is used to request establishment of a PDU session or request activation of an established PDU session; forward the signaling message to the control plane device; forward the data in the uplink data packet sent by the UE based on the data forwarding message carried in the uplink data packet sent by the UE before an available PDU session exists. In this disclosure, before there is an available PDU session, the UE will additionally carry a data forwarding message in addition to the signaling message in the data packet, so that while triggering the PDU session establishment or PDU session activation process, it can also The data is sent through the data forwarding message, so that the data packet can be sent in real time even when there is no available PDU session, and the delay requirement of the low-latency service is met.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a data sending method, device and equipment. Background technique [0002] The fifth-generation mobile communication technology (5th-Generation Mobile Communication, 5G), as an extension of the fourth-generation mobile communication technology (the 4th Generation Mobile Communication, 4G), has become a research hotspot nowadays. Such as figure 1 As shown, enhanced mobile broadband services (enhanced Mobile BroadBand, eMBB), large-capacity machine-type communications (massive Machine-Type Communications, mMTC), high-reliability and low-latency communications (Ultra-Reliable and Low-Latency Communications, URLLC), are 5G network The three major businesses in Especially the URLLC service, due to its low latency and high reliability, is currently widely used in scenarios such as Internet of Vehicles, industrial control, and smart grid. [0003] In related tec...
