[0071] First, let me explain the terms used in this application:
[0072] Network-side equipment is used to provide communication services to terminal devices, and includes access network equipment and core network equipment.
[0073] Access network equipment, also known as a base station (BS) or base station equipment, is a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, in 2G networks, equipment providing base station functions includes base transceiver stations (BTS); in 3G networks, it includes nodes (NodeBs); in 4G networks, it includes evolved nodes (eNBs); in wireless local area networks (WLANs), it is the access point (AP); in 5G New Radio (NR), it includes gNBs and further evolved nodes (ng-eNBs). gNBs communicate with terminals using NR technology, while ng-eNBs communicate with terminals using evolved universal terrestrial radio access (E-UTRA) technology. Both gNBs and ng-eNBs can connect to core network equipment. The base station in this application embodiment also includes equipment that provides base station functions in future new communication systems.
[0074] Core network equipment is a device deployed in the core network (CN) to connect the radio access network and external networks, such as data networks. Core network equipment can be configured with Access and Mobility Management (AMF), Session Management (SMF), and User Plane (UPF) functions. AMF performs user access and mobility management, SMF allocates IP addresses for terminal devices, performs session management and accounting, and UPF performs user plane data forwarding.
[0075] Terminal equipment refers to equipment that includes wireless transceiver capabilities and can cooperate with network-side equipment to provide communication services to users. 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 device, user terminal equipment, wireless communication equipment, user agent, or user device, etc. Examples of terminal devices currently include: mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), 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 capabilities, computing devices or other processing devices connected to wireless modems, in-vehicle devices, shipboard devices, and wearable devices.
[0076] In this application, the term "comprising" and its variations can refer to non-limiting inclusion; the term "or" and its variations can refer to "and / or". "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.
[0077] In this 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 this application, the term "at least one" refers to one or more, and "more than one" refers to two or more. In this application, the term "at least one of the following" or similar expressions refer to any combination of these items, including any combination of a single item or a plurality of items. For example, at least one of a, b, or c can represent: a, b, c, ab, a--c, bc, or abc, where a, b, and c can be single or multiple.
[0078] In this application, the words "in some embodiments," "exemplary," or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "in some embodiments," "exemplary," or "for example" should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the words "in some embodiments," "exemplary," or "for example" is intended to present the relevant concepts in a specific manner. In this application, the words "in the case of" or "when" indicate a condition.
[0079] In the 5GS optimization of the control plane IoT, the uplink data of the terminal device can be encapsulated in the Non-Access Stratum (NAS) message and sent in the control plane.
[0080] The following is combined Figure 1 This example illustrates the process of sending uplink data from the control plane.
[0081] Figure 1 A flowchart illustrating the flow of uplink data provided for related technologies. For example... Figure 1 As shown, it includes:
[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 process, a timer (e.g., T3517) is started, and a Control Plane Service Request message is sent to the core network device. The Control Plane Service Request message encapsulates uplink data.
[0083] S102. The core network equipment sends a service request acceptance message corresponding to the control plane service request message to the terminal equipment.
[0084] S103. During uplink non-access stratum transport (UL NAS Transport), the terminal equipment sends uplink non-access stratum transport messages to the core network equipment.
[0085] After the service request process ends, 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 typically greater than 500 milliseconds (ms).
[0086] During a service request, the control plane service request message encapsulates uplink data. When the amount of uplink data is large, the control plane service request message becomes longer, requiring more time (e.g., longer Transmission Time Intervals, TTIs) to complete its transmission, thus increasing the likelihood of service request timeouts. Furthermore, when the amount of uplink data is large, the terminal device may divide the control plane service request message into multiple segments for transmission. However, due to factors such as channel conditions and bandwidth, the success rate of transmitting the control plane service request message is low (the failure of any segment will result in the failure of the entire control plane service request message transmission), further reducing the success rate of the service request process and consequently the success rate of uplink data transmission.
[0087] In view of this, embodiments of this application provide an uplink data transmission method. In this method, when a terminal device sends a control plane service request message, it selects an appropriate method to send uplink data based on the channel quality between the terminal device and the network-side device to solve the problem of low uplink data transmission success rate.
[0088] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0090] S201. The terminal device obtains the channel quality between the terminal device and the network-side device.
[0091] In some embodiments, the terminal device executes S201 after completing random access and establishing an RRC connection; or executes S201 after completing random access and before establishing an RRC connection. The time for executing S201 is not limited in this embodiment.
[0092] In some embodiments, the channel quality can be any of the following:

[0095] Reference Signal Received Quality (RSRQ).
[0096] Channel quality can be the channel quality of the uplink channel.
[0097] In some embodiments, the terminal device obtains channel quality by: measuring a reference signal transmitted through a downlink channel to obtain the channel quality of the downlink channel, and evaluating the channel quality of the uplink channel based on the channel quality of the downlink channel, wherein the uplink channel and the downlink channel are channels between the terminal device and the network-side device.

[0103] In some embodiments, the quality threshold may be pre-stored in the terminal device.
[0104] In some embodiments, the quality threshold can be carried through broadcast messages and / or dedicated signaling. Broadcast messages and dedicated signaling are information sent from network-side devices to terminal devices.

[0106] In some embodiments, the first control plane service request message is a CIoT small data container information element.
[0107] In some embodiments, the payload container information element of the first control plane service request message includes uplink data.
[0108] In some embodiments, based on S202a, after receiving the service request acceptance message corresponding to the first control plane service request message, the terminal device may send an uplink non-access stratum transmission message to the network-side device. The uplink non-access stratum transmission message does not include uplink data.
[0109] The service request acceptance message corresponding to the first control plane service request message indicates that the first control plane service request message was sent successfully, which can also be understood as the service request process being successful.
[0110] The terminal device receives the service request acceptance message corresponding to the first control plane service request message, indicating that the first control plane service request message was successfully sent.
[0111] In some embodiments, the uplink data is IoT data.
[0112] In some embodiments, IoT data includes one or more of the following: temperature of the terminal device, humidity of the terminal device, location information of the terminal device, speed information of the terminal device, status information of the terminal device, behavior information of the terminal device, etc.
[0113] S202b: In response to the channel quality being less than the quality threshold, the terminal device sends an uplink non-access stratum transmission message to the network-side device. The uplink non-access stratum transmission message includes uplink data.
[0114] In some embodiments, the payload container cell of the uplink non-access stratum transmission message includes uplink data.
[0115] In this embodiment, when the channel quality is greater than or equal to the quality threshold, the terminal device sends a first control plane service request message including uplink data to the network-side device; or, when the channel quality is less than the quality threshold, it sends an uplink non-access stratum transmission message including uplink data to the network-side device. This achieves the purpose of flexibly selecting the uplink data transmission method according to the channel quality, improving the flexibility of uplink data transmission, and thus improving the uplink data transmission success rate.
[0116] Based on S202a, combined with the following Figure 3 and Figure 4 The method for transmitting uplink data provided in this application is described.
[0117] Figure 3 This is the second flowchart illustrating the uplink data transmission method provided in this application. Figure 3 As shown, the method includes:
[0118] S301. The terminal device obtains the channel quality and channel bandwidth between the terminal device and the network-side device.
[0119] Channel bandwidth refers to the uplink channel bandwidth between the terminal device and the network-side device.
[0120] In some embodiments, the channel bandwidth is the bandwidth of the uplink bandwidth part (BWP) of fifth-generation mobile communication technology (5G).
[0121] Alternatively, the channel bandwidth can also be the uplink channel bandwidth of other generations of mobile communication technologies. Other generations of mobile communication technologies include, for example, third-generation mobile communication technology (3G), fourth-generation mobile communication technology (4G), or future mobile communication technologies after fifth-generation mobile communication technology (e.g., sixth-generation mobile communication technology (6G)).
[0122] In some embodiments, the terminal device obtains the channel bandwidth of the uplink channel, including: the terminal device receiving the channel bandwidth sent by the network-side device.

The CIoT small data container information element of the first control plane service request message includes uplink data.
[0125] The data volume threshold is, for example, 254 bytes, but it can also be other values, which will not be detailed here.
[0126] In some embodiments, the data volume threshold may be pre-stored in the terminal device.
[0127] In some embodiments, the data volume threshold can be carried through broadcast messages and / or dedicated signaling. Broadcast messages and dedicated signaling are information sent from the network-side device to the terminal device.
[0128] S302b, in response to the fact that the channel quality is greater than or equal to the quality threshold, the amount of uplink data is greater than the data amount threshold, and the channel bandwidth between the terminal device and the network-side device is greater than or equal to the bandwidth threshold, the terminal device sends a first control plane service request message to the network-side device, wherein the payload container cell of the first control plane service request message includes uplink data.
[0129] In some embodiments, the bandwidth threshold may be pre-stored in the terminal device.
[0130] In some embodiments, the bandwidth threshold can be carried through broadcast messages and / or dedicated signaling. Broadcast messages and dedicated signaling are information sent from network-side devices to terminal devices.
[0131] In some embodiments, S303 is executed after S302a or S302b.
[0132] S303. Upon receiving the first control plane service request message, the network-side device sends a service request acceptance message corresponding to the first control plane service request message to the terminal device.
[0133] S304. In response to receiving the service request acceptance message corresponding to the first control plane service request message, the terminal device sends an uplink non-access stratum transmission message to the network-side device. The uplink non-access stratum transmission message does not include uplink data.
[0134] Optionally, the execution method of S304 is the same as that of S103, and will not be described again here.
[0135] exist Figure 3 In the uplink data transmission method provided in the embodiment, when the channel quality is good (good channel quality can be understood as a suitable channel environment) and the amount of uplink data is small, the uplink data is carried in the CIoT small data container cell of the first control plane service request message. 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 cell of the first control plane service request message. This achieves the purpose of flexibly selecting the uplink data carrying method 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.

[0140] Specifically, the execution methods of S401-S402b are the same as those of S301-S302b, and the execution process of S401-S402b will not be described again here.
[0141] S403. In response to not receiving a service request acceptance message corresponding to the first control plane service request message, the terminal device sends a second control plane service request message to the network-side device. The second control plane service request message does not include uplink data.
[0142] In some embodiments, if the terminal device does not receive the service request acceptance message corresponding to the first control plane service request message, it can be understood as the first control plane service request message failing to be sent.
[0143] In some embodiments, the second control plane service request message can be understood as a control plane service request message that does not include uplink data.
[0144] S404. Upon receiving the second control plane service request message, the network-side device sends a service request acceptance message corresponding to the second control plane service request message to the terminal device.

[0151] exist Figure 4 In the uplink data transmission method provided in the embodiment, if sending a control plane service request message including uplink data fails (i.e., sending a first control plane service request message fails), a control plane service request message excluding uplink data is sent (i.e., a second control plane service request message is sent), thereby improving the success rate of sending the control plane service request message and thus improving the success rate of the service request process. Furthermore, if the service request process is successful, the terminal device sends an uplink non-access stratum transmission message including uplink data to the network-side device, further improving the success rate of uplink data transmission.
[0152] Based on S202b, combined with the following Figure 5 and Figure 6 The method for transmitting uplink data provided in the embodiments of this application will be described.

[0161] exist Figure 5 In the uplink data transmission method provided in the embodiment, when the channel quality is poor (good channel quality can be understood as a harsh channel environment), sending a control plane service request message that does not include uplink data can improve the success rate of sending the control plane service request message, thereby improving the success rate of the service request process. Furthermore, assuming the service request process is successful, the terminal device sends an uplink non-access stratum transmission message including uplink data to the network-side device, further improving the success rate of uplink data transmission.

The second control plane service request message does not include uplink data.
[0165] S603. Upon receiving the second control plane service request message, the network-side device sends a service request acceptance message corresponding to the second control plane service request message to the terminal device.
[0166] In some embodiments, S604a or S604b may be executed after S603.
[0167] S604a. In response to not receiving a service request acceptance message corresponding to the second control plane service request message, the terminal device sends a second control plane service request message to the network device.
[0168] Specifically, the execution method of S604a is the same as that of S405a, and the execution process of S604a will not be described again here.
[0169] S604b: In response to receiving the service request acceptance message corresponding to the second control plane service request message, the terminal device sends an uplink non-access stratum transmission message to the network-side device, the uplink non-access stratum transmission message including uplink data.
[0170] exist Figure 6 In the uplink data transmission method provided in the embodiment, when the channel quality is good, the amount of uplink data is large, and the channel bandwidth is small (small channel bandwidth can be understood as limited channel resources), sending a control plane service request message without uplink data can improve the success rate of sending the control plane service request message, thereby improving the success rate of the service request process. Furthermore, assuming the service request process is successful, the terminal device sends an uplink non-access stratum transmission message including uplink data to the network-side device, further improving the uplink data transmission success rate.
[0171] Based on the above embodiments, and by combining the above embodiments, the following can be obtained: Figure 7 The method for transmitting uplink data performed by the terminal device shown.
[0172] Figure 7 This is the sixth flowchart illustrating the uplink data transmission method provided in this application. Figure 7 As shown, the method includes:
[0173] S701. Obtain the channel quality and channel bandwidth between the terminal device and the network-side device.
[0174] S702. Determine whether the channel quality is greater than or equal to the quality threshold.
[0175] If not, execute S703; otherwise, execute S704.
[0176] S703, Send a second control plane service request message, and then execute S709.
[0177] S704. Determine whether the amount of data in the upstream data is less than or equal to the data amount threshold.
[0178] If yes, then execute S705; otherwise, execute S706.
[0179] S705, Send a first control plane service request message, wherein the CIoT small data container information 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, then execute S707; otherwise, execute S703.
[0182] S707. Send a first control plane service request message, the payload container of the first control plane service request message includes uplink data, and execute S708.
[0183] S708. Determine whether a service request acceptance message corresponding to the first control plane service request message has been received. The service request acceptance message corresponding to the first control plane service request message is referred to as the first service request acceptance message for example.
[0184] If yes, then the uplink data transmission ends; otherwise, execute S703.
[0185] S709. Determine whether a service request acceptance message corresponding to the second control plane service request message has been received. The service request acceptance message corresponding to the second control plane service request message is referred to as the second service request acceptance message for example.
[0186] If not, execute S710; otherwise, execute S703.
[0187] S710, Send an uplink non-access stratum transmission message. The payload container cell of the uplink non-access stratum transmission message includes uplink data. The uplink data transmission ends.
[0188] In some embodiments, if the terminal device consistently uses the control plane service request message to carry uplink data, the probability of service request failure will increase in cases of poor channel environment or insufficient radio resources. If the terminal device consistently uses the uplink non-access stratum transmission message to carry uplink data, the uplink data will be delayed. If the terminal device randomly selects between the control plane service request message and the uplink non-access stratum transmission message to carry uplink data, unpredictable risks may occur.
[0189] In this application, under favorable channel conditions and with sufficient radio resources, control plane service request messages are used to carry uplink data. This reduces the probability of service request failure and allows uplink data to be transmitted as early as possible. Under poor channel conditions, insufficient radio resources, and control plane service request message transmission failures, uplink non-access stratum transmission messages are used to carry uplink data. This reduces the probability of service request failure and improves the success rate of uplink data transmission. The uplink data transmission method provided in this application achieves the goal of transmitting uplink data as early as possible when the service request process is successfully completed.
