Terminal equipment can also be called user equipment (UE), access terminal equipment, user unit, user station, mobile station, mobile station, remote station, remote terminal equipment, mobile equipment, user terminal equipment, wireless communication equipment, user agent or user device, etc. At present, some examples of terminal devices include: mobile phones, tablet computers, laptop computers, PDAs, mobile internet devices (MID), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self driving, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication functions, computing devices or other processing devices connected to wireless modems, vehicle-mounted devices, ship-mounted devices, wearable devices, etc.

[0076] In this application, the term "include" and its variations may refer to non-restrictive inclusion; the term "or" and its variations may refer to "and / or". "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0077] In the present application, the terms "first", "second", etc. are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. In the present application, the term "at least one" refers to one or more, and "plurality" refers to two or more.

Any embodiment or design described in this application as "in some embodiments", "exemplary" or "for example" should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "in some embodiments", "exemplary" or "for example" is intended to present related concepts in a concrete way. In this application, words such as "under the condition of" or "when" represent a condition.

[0079] In the control plane IoT 5GS optimization, the uplink data of the terminal device can be encapsulated in the Non-Access Stratum (NAS) message and sent on the control plane.

[0080] Combine the following Figure 1 The process of sending uplink data on the control plane is exemplified.

[0081] Figure 1 A schematic diagram of the flow of uplink data provided for related technologies. Figure 1 As shown, including:

[0082] S101. After completing random access and establishing a radio resource control (RRC) connection between the terminal device and the access network device, during the service request (Service Request) process, start a timer (the timer is, for example, T3517), and send a control plane service request (Control Plane Service Request) message to the core network device. The control plane service request message is encapsulated with uplink data.

[0083] S102. The core network device sends a service request acceptance message corresponding to the control plane service request message to the terminal device.

[0084] S103. During an uplink non-access layer transmission (UL NAS Transport) process, the terminal device sends an uplink non-access layer transmission message to a core network device.

[0085] After the service request process is finished, the terminal device executes S103. For non-terrestrial network (NTN) communication, the duration of the service request process between the terminal device and a satellite in geostationary Earth Orbit (GEO) in transparent forwarding mode is usually greater than 500 milliseconds (ms).

[0086] In the process of service request, uplink data is encapsulated in the control plane service request message. When the amount of uplink data is large, the length of the control plane service request message is large, and it takes a longer time (for example, more transmission time intervals (TTI)) to complete the sending of the control plane service request message, which makes it more likely that the service request process will time out. In addition, when the amount of uplink data is large, the terminal device divides the control plane service request message into multiple segments for sending. Under the influence of channel environment, bandwidth size, etc., the success rate of sending the control plane service request message is low (wherein, the failure of any segment transmission will cause the failure of the control plane service request message transmission), which makes the success rate of the service request process low, and then leads to a low success rate of uplink data transmission.

[0087] In view of this, an embodiment of the present application provides a method for transmitting uplink data. In this method, when a terminal device sends a control plane service request message, a technical means for sending uplink data is selected in an appropriate manner according to the channel quality between the terminal device and the network side device, so as to solve the problem of low success rate in sending uplink data.

[0088] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments.

When the channel quality is good, the amount of uplink data is large, and the channel bandwidth is large (large channel bandwidth can be understood as sufficient channel resources), the uplink data is carried in the payload container element of the first control plane service request message. This achieves the purpose of flexibly selecting the carrying method of the uplink data in the control plane service request message according to the channel environment, the amount of uplink data, and the channel resources, thereby improving the success rate of sending the control plane service request message, and enabling the uplink data to be sent as early as possible.

[0173] S701. Obtain channel quality and channel bandwidth between a terminal device and a network side device.

[0178] If yes, execute S705; otherwise, execute S706.

[0179] S705. Send a first control plane service request message, the CIoT small data container element of the first control plane service request message includes uplink data, and execute S708.

[0180] S706: Determine whether the channel bandwidth is greater than or equal to the bandwidth threshold.

[0181] If yes, execute S707; otherwise, execute S703.

[0182] S707: Send a first control plane service request message, wherein the payload container information element (Payload Container) of the first control plane service request message includes uplink data, and execute S708.

[0185] S709: Determine whether a service request acceptance message corresponding to the second control plane service request message is received. The service request acceptance message corresponding to the second control plane service request message is, for example, referred to as a second service request acceptance message.

[0187] S710: Send an uplink non-access layer transmission message, the payload container cell of the uplink non-access layer transmission message includes uplink data, and the uplink data transmission is completed.

[0188] In some embodiments, if the terminal device fixedly uses the control plane service request message to carry uplink data, then in the case of a poor channel environment or insufficient wireless resources, the probability of failure of the service request process will increase. If the terminal device fixedly uses the uplink non-access layer transmission message to carry uplink data, the uplink data will be delayed in sending. If the terminal device randomly selects one of the control plane service request message and the uplink non-access layer transmission message to carry uplink data, unexpected risks may occur.

[0189] In the present application, when the channel environment is good and the wireless resources are sufficient, the control plane service request message is used to carry the uplink data, so that the uplink data can be transmitted as early as possible while reducing the probability of failure of the service request process. In the case of a poor channel environment, insufficient wireless resources, and failure to send the control plane service request message, the uplink non-access layer transmission message is used to carry the uplink data, which can reduce the probability of failure of the service request process and improve the success rate of uplink data transmission.
