Embodiment 1

[0151] like Figure 4 shown, including:

[0152] Step 401: After attaching to the network, the UE sends a PDU session establishment request to the SMF via the AN and the AMF.

[0153] Step 402: Send a PDU session establishment permission message carrying the QoS identifier of the PDU session level to the terminal.

[0154] In this step, after the SMF determines that this PDU session can be used to transmit small data through control plane signaling, it can determine the QoS of the PDU session level according to the information obtained from the subscription database or according to the QoS requirements of the service flows supported in this PDU session identified and sent to the UE. For example, SMF can directly obtain the PDU session-level QoS identifier from the subscription database, or SMF uses the default 5QI (5QI (5G QoS Indicator, 5G QoS indication) obtained from the subscription database as the PDU session-level QoS identifier, or SMF obtains the PDU session-level Qo...

Embodiment 2

[0162] like Figure 5 shown, including:

[0163] Step 501: The SMF sends the service data filter at the service data flow level and the QoS identifier corresponding to the service data filter to the UPF during the establishment or modification of the PDU session.

[0164] Step 502: The SMF sends the service data flow level QoS rule to the UE during the establishment or modification of the PDU session, and the QoS rule includes a service data filter and a QoS identifier.

Abstract

The invention provides an information transmission method, a terminal and network equipment, and solves the problem that in the prior art, UE is limited to carry UE-level QoS parameters in an RRC message, so that one piece of UE can only support small data services with the same QoS requirement, and the service application of an Internet of Things terminal is limited. The method comprises the following steps: acquiring a QoS identifier of a PDU session level or a service level sent by an SMF entity; when the data needs to be sent through the control plane message, sending an RRC message to thebase station, wherein the RRC message carries a non-access stratum message containing the user data and the QoS identifier of a PDU session level or a service level corresponding to the user data. According to the embodiment of the invention, one terminal can support small data services with different QoS requirements, and the service application scene of the Internet of Things terminal is expanded.

Description

technical field [0001] The present invention relates to the technical field of communication applications, in particular to an information transmission method, terminal and network equipment. Background technique [0002] In the next generation (Next Gen) network, support for Internet of things (IOT) communication needs to be considered. One of the important scenarios is that some IoT terminals have a relatively long period of sending data, and the amount of data sent is relatively small. In this case, instead of transmitting data through the traditional user plane, the data is carried in the signaling for transmission while the terminal and the network interact with each other, thereby saving the cost of establishing and maintaining the user plane. When different user equipments (User Equipment, UE, also referred to as terminals) transmit small data through the control plane, the base station needs to allocate resources with different priorities according to different requi...
