Description

Technical Field

[0001] The present application relates to the field of communications, and more specifically, to a transmission method and a transmission device. Background Art

[0002] In the fifth generation mobile communication technology (5th generation, 5G) quality of a service (QoS) flow, for example, if a terminal device needs to upload photos to a server for image enhancement services, a file transfer protocol (FTP) is generally used to upload the photos.

[0003] However, for cloud photo enhancement scenarios, if cloud photos are to achieve an experience equivalent to that of local images, it generally takes about 2 seconds to complete the uplink transmission of the photos. The base station does not have strict transmission resource guarantees, and there is no fixed constraint on the delay in transmitting a photo. Therefore, transmission resources cannot be guaranteed, and the experience requirements cannot be met. Summary of the invention

[0004] The embodiments of the present application provide a transmission method and a transmission device, which can ensure the transmission rate of the target service and thus meet the customer experience requirements.

[0005] In order to achieve the above objectives, this application adopts the following technical solutions:

[0006] In the first aspect, a transmission method is provided, which can be executed by a terminal device, or by a component of the terminal device, such as a processor, chip, or chip system of the terminal device, or by a logic module or software that can realize all or part of the functions of the terminal device. Taking the method that can be executed by a terminal device as an example, the method includes: the terminal device sends a request message to an access network device, the request message is used to request the processing capability of the target service to be transmitted; the terminal device receives a resource response message from the access network device, the resource response message is used to indicate the second data volume information, the second data volume information is used to indicate the processing capability of the target service supported by the access network device for transmission within the first time delay, the processing capability is the data volume or the data transmission rate; the terminal device sends the data of the target service to the access network device according to the second data volume information.

[0007] In the transmission method provided by the embodiment of the present application, when the target service arrives, the terminal device requests the processing capacity for transmitting the target service. Furthermore, the access network device can feedback to the terminal device the second data volume information indicating the processing capacity of the target service supported by the access network device for transmission within the first time delay, so that the terminal device sends the data of the target service to the access network device according to the second data volume information. On the one hand, since the scheme is initiated when the target service arrives, the overhead of reserving resources in advance before the service arrives is saved. On the other hand, since the terminal device sends the data of the target service according to the second data volume information fed back by the access network device, this scheme can ensure the transmission rate of the target service.

[0008] The second data volume information is determined based on the first data volume information, and the first data volume information is used to indicate the processing capacity of the target service requested to be transmitted within the first time delay.

[0009] The processing capacity of the target service of the embodiment of the present application is the data volume or data transmission rate of the target service allowed to be transmitted by the access network device within the first delay. The data volume of the target service allowed to be transmitted by the access network device within the first delay can be understood as the data volume that the access network device can receive / process within a certain time; the data transmission rate of the target service allowed to be transmitted by the access network device within the first delay can be understood as the access network device can receive / process the data of the target service at a certain data transmission rate. It should be noted that this data volume is the amount of data that can be transmitted within the first delay requirement estimated by the access network device based on the current channel conditions and load conditions of the terminal device. After the subsequent service actually arrives, the access network device may still schedule the data volume of the target service under the condition of less than the first delay or more than the first delay. Alternatively, this data transmission rate is the data that the access network device estimates can transmit the target service at a certain data transmission rate based on the current channel conditions and load conditions of the terminal device. After the subsequent service actually arrives, the access network device may still transmit the data of the target service at a transmission rate lower than or higher than the data transmission rate. In addition, the first delay can be called the first duration period, the first time period, the first time interval, etc., and this application does not limit this.

[0010] In one possible implementation, the request message of an embodiment of the present application also includes estimated arrival time information of the target service. In one possible implementation, the estimated arrival time information of the target service is used to indicate that the estimated arrival time of the target service is the time difference between the time when the actual data arrives at the access layer of the terminal device and the time when the terminal device sends the request message. The request message includes the estimated arrival time of the target service, which can make the processing capacity for transmitting the target service determined by the access network device more accurate, thereby saving resource overhead.

[0011] For the first data volume information:

[0012] In a possible implementation, the request message in the embodiment of the present application includes first data volume information and indication information of the first time delay, and the first data volume information is used to indicate the processing capability of the target service requested by the terminal device to be transmitted within the first time delay. The first data volume information is used to indicate the processing capability of the target service requested by the terminal device to be transmitted within the first time delay, that is, when the target service arrives, the terminal device can directly carry the first data volume information and the indication information of the first time delay in the request message to request the processing capability for transmitting the target service.

[0013] In another possible implementation, the first data volume information is used to indicate the core network device to indicate the processing capability of the target service transmitted within the first delay. The first data volume information is used to indicate the core network device to indicate the processing capability of the target service transmitted within the first delay, that is, when the target service arrives, a new QoS flow is triggered, and in the QoS flow establishment request, the core network device sends the first data volume information and the indication information of the first delay as parameters for establishing the QoS flow to the access network device, so that the access network device establishes a QoS flow dedicated to the target service according to the first data volume information and the indication information of the first delay.

[0014] For resource response messages:

[0015] In a possible implementation, the resource response message includes the second data volume information, so that the terminal device directly obtains the second data volume information without judgment, and sends the target service data to the access network device according to the second data volume information. In this way, the terminal device does not need additional judgment steps, and the implementation complexity is low.

[0016] In another possible implementation, the resource response message does not carry data volume information, and the second data volume information indicated by the resource response message is the first data volume information indicated in the first configuration message; and / or, the resource response message does not carry data volume information, and the second data volume information indicated by the resource response message is the first data volume information indicated in the second configuration message. That is, in this solution, the terminal device obtains the second data volume information through its own judgment, and sends the data of the target service to the access network device according to the second data volume information. Since the terminal device determines through its own judgment that the second data volume information indicated by the resource response message is the first data volume information indicated in the first configuration message or the second configuration message, the resource response message only needs to carry one indication to enable the terminal device to determine the second data volume information, thereby saving more resource overhead of the resource response message.

[0017] In a possible implementation, the method also includes: the terminal device receives a first configuration message from the access network device, the first configuration message includes a first initial transmission rate and / or a first data volume information, the first configuration message is used to indicate the establishment of a data bearer for a quality of service (QoS) flow that carries the target service, wherein the first initial transmission rate indicates an initial rate for sending data of the target service to the access network device.

[0018] And / or, the terminal device receives a second configuration message from the core network device, the second configuration message includes the first data volume information, and the second configuration message is used to indicate the establishment of a QoS flow carrying the target service, so that the terminal device determines the relevant information of the QoS flow used for the transmission of the target service, and then initiates a request message for requesting the processing capability of the target service.

[0019] In a possible implementation, the method further includes: the terminal device sends a first request message to the core network device, wherein the first request message includes the first data volume information and the indication information of the first delay, or the first request message includes the third data volume information and the indication information of the first delay, the third data volume information is used for the access network device to determine the first data volume information, and the first request message is used to request the configuration of the QoS flow. That is, the core network device determines the request to establish the QoS flow carrying the target service according to the first request message received from the terminal device. Among them, the first request message may include the first data volume information and the indication information of the first delay, and may also include the third data volume information and the indication information of the first delay. When the first request message includes the first data volume information and the indication information of the first delay, the access network device itself does not need to perform capability judgment, and directly establishes the QoS flow carrying the target service according to the request of the core network device, wherein the QoS flow carrying the target service corresponds to the first data volume information, so that the access network device does not need to perform additional judgment. When the first request message includes the third data volume information and the indication information of the first delay, the access network device makes a judgment based on its own capabilities, and establishes a QoS flow carrying the target service based on the request of the core network device and its own capabilities, wherein the QoS flow carrying the target service corresponds to the first data volume information, so that the second data volume information determined by the access network device is more accurate.

[0020] In a possible implementation, the resource response message further includes: a second initial transmission rate, and the method further includes: the terminal device determines the sending window of the application transmission protocol of the data of the target service according to the second initial transmission rate. The resource response message includes the second initial transmission rate, so that the terminal device can send the data of the target service to the access network device according to the initial transmission rate, saving the overhead of the terminal device trying to determine the transmission rate multiple times.

[0021] In one possible implementation, the terminal device sends the target service data to the access network device according to the second data volume information, including: when the data volume indicated by the second data volume information is greater than or equal to the first threshold, the terminal device sends the target service data to the access network device according to the parameters of the target service.

[0022] In a possible implementation, when the data volume indicated by the second data volume information is less than the first threshold, the terminal device does not send the target service data to the access network device. Wherein, when the data volume indicated by the second data volume information cannot be used to transmit the data volume of the target service, the terminal device does not send the target service data to the access network device, thereby preventing the terminal device from transmitting ineffectively and saving resource overhead.

[0023] In the second aspect, a transmission method is provided, which can be executed by an access network device, or by a component of the access network device, such as a processor, chip, or chip system of the access network device, or by a logic module or software that can realize all or part of the functions of the access network device. Taking the method being executed by the access network device as an example, the method includes: the access network device receives a request message from a terminal device, the request message is used to request the processing capability of the target service to be transmitted; the access network device sends a resource response message to the terminal device, the resource response message is used to indicate the second data volume information, the second data volume information is used to indicate the processing capability of the target service supported by the access network device for transmission within the first delay, the processing capability being the data volume or the data transmission rate.

[0024] In the transmission method provided by the embodiment of the present application, when the target service arrives, the terminal device requests the processing capacity for transmitting the target service. Furthermore, the access network device can feedback to the terminal device the second data volume information indicating the processing capacity of the target service supported by the access network device for transmission within the first time delay, so that the terminal device sends the data of the target service to the access network device according to the second data volume information. On the one hand, since the scheme is initiated when the target service arrives, the overhead of reserving resources in advance before the service arrives is saved. On the other hand, since the terminal device sends the data of the target service according to the second data volume information fed back by the access network device, this scheme can ensure the transmission rate of the target service.

[0025] In the embodiment of the present application, the second data volume information is determined based on the first data volume information, and the first data volume information is used to indicate the processing capacity of the target service requested to be transmitted within the first time delay.

[0026] The processing capacity of the target service of the embodiment of the present application is the data volume or data transmission rate of the target service allowed to be transmitted by the access network device within the first delay. The data volume of the target service allowed to be transmitted by the access network device within the first delay can be understood as the data volume that the access network device can receive / process within a certain time; the data transmission rate of the target service allowed to be transmitted by the access network device within the first delay can be understood as the access network device can receive / process the data of the target service at a certain data transmission rate. It should be noted that this data volume is the amount of data that can be transmitted within the first delay requirement estimated by the access network device based on the current channel conditions and load conditions of the terminal device. After the subsequent service actually arrives, the access network device may still schedule the data volume of the target service under the condition of less than the first delay or more than the first delay. Alternatively, this data transmission rate is the data that the access network device estimates can transmit the target service at a certain data transmission rate based on the current channel conditions and load conditions of the terminal device. After the subsequent service actually arrives, the access network device may still transmit the data of the target service at a transmission rate lower than or higher than the data transmission rate. In addition, the first delay can be called the first duration period, the first time period, the first time interval, etc., and this application does not limit this.

[0027] In an embodiment of the present application, the request message also includes estimated arrival time information of the target service. In one possible implementation method, the estimated arrival time information of the target service is used to indicate that the estimated arrival time of the target service is the time difference between the time when the actual data arrives at the access layer of the terminal device and the time when the terminal device sends the request message. The request message includes the estimated arrival time of the target service, which can make the processing capacity for transmitting the target service determined by the access network device more accurate, thereby saving resource overhead.

[0028] For the first data volume information:

[0029] In a possible implementation, the request message includes first data volume information and indication information of the first time delay, and the first data volume information is used to indicate the processing capability of the target service requested by the terminal device to be transmitted within the first time delay. The first data volume information is used to indicate the processing capability of the target service requested by the terminal device to be transmitted within the first time delay, that is, when the target service arrives, the terminal device can directly carry the first data volume information and the indication information of the first time delay in the request message to request the processing capability for transmitting the target service.

[0030] In another possible implementation, the first data volume information is used to indicate the core network device to indicate the processing capability of the target service transmitted within the first time delay. The first data volume information is used to indicate the core network device to indicate the processing capability of the target service transmitted within the first time delay, that is, when the target service arrives, a new QoS flow is triggered, and in the QoS flow establishment request, the core network device sends the first data volume information and the indication information of the first time delay as parameters for establishing the QoS flow to the access network device, so that the access network device establishes a QoS flow dedicated to the target service according to the first data volume information and the indication information of the first time delay.

[0031] For resource response messages:

[0032] In one possible implementation, the resource response message includes the second data volume information, so that the terminal device can directly obtain the second data volume information without judgment, and send the target service data to the access network device according to the second data volume information. The terminal device does not require additional judgment steps, and the implementation complexity is low.

[0033] In another possible implementation, the resource response message does not carry data volume information, and the second data volume information indicated by the resource response message is the first data volume indicated in the first configuration message, and / or the resource response message does not carry data volume information, and the second data volume information indicated by the resource response message is the first data volume information indicated in the second configuration message. That is, in this solution, the terminal device obtains the second data volume information through its own judgment, and sends the data of the target service to the access network device according to the second data volume information. Since the terminal device determines through its own judgment that the second data volume information indicated by the resource response message is the first data volume indicated in the first configuration message or the second configuration message, the resource response message only needs to carry one indication to enable the terminal device to determine the second data volume information, thereby saving more resource overhead of the resource response message.

[0034] In a possible implementation, the method further includes: the access network device receives first data volume information and indication information of the first delay from the core network device, wherein the first data volume information comes from the terminal device or the server; or the access network device receives third data volume information and indication information of the first delay from the core network device, and determines the first data volume information according to the third data volume information, wherein the third data volume information comes from the terminal device or the server. When the access network device receives the first data volume information and indication information of the first delay from the core network device, the access network device itself does not need to make a capability judgment, and directly establishes a QoS flow carrying the target service according to the request of the core network device, wherein the QoS flow carrying the target service corresponds to the first data volume information, so that the access network device does not need to make additional judgments. When the access network device receives the third data volume information and indication information of the first delay from the core network device, the access network device makes a judgment according to its own capabilities, and establishes a QoS flow carrying the target service according to the request of the core network device and its own capabilities, wherein the QoS flow carrying the target service corresponds to the first data volume information, so that the second data volume information determined by the access network device is more accurate. Among them, the first data volume information and the indication information of the first delay, or the third data volume information and the indication information of the first delay, may be obtained by the core network device from the terminal device or the server, so that the core network device sends a request to establish a bearer QoS flow according to the request of the server or the terminal.

[0035] In a possible implementation, the method further includes: the access network device sends the first data volume information to the core network device, so that the access network device and the core network device align the information of the QoS flow for the target service.

[0036] In a possible implementation, the method further includes: the access network device sends a first configuration message to the terminal device, the first configuration message includes a first initial transmission rate and / or the first data volume information, and the first configuration message is used to indicate the establishment of a data bearer of a quality of service QoS flow that carries the target service. The terminal device determines the relevant information of the QoS flow used for the transmission of the target service, and then initiates a request message for requesting the processing capability of the target service.

[0037] In a possible implementation, the method further includes: the resource response message includes a second initial transmission rate, and the second initial transmission rate is used to determine the sending window of the application transmission protocol of the data of the target service. The resource response message includes the second initial transmission rate, so that the terminal device can send the data of the target service to the access network device according to the initial transmission rate, saving the terminal device the overhead of multiple attempts to determine the transmission rate.

[0038] In a possible implementation, the method further includes: the access network device receives data of a target service from the terminal device, wherein the data of the target service is sent by the terminal device according to parameters of the target service when the data volume indicated by the second data volume information is greater than or equal to the first threshold, and the parameters of the target service are determined by the terminal device according to the second data volume information indicated by the resource response message. When the data volume indicated by the second data volume information cannot be used to transmit the data volume of the target service, the terminal device does not send the data of the target service to the access network device, thereby preventing the terminal device from transmitting ineffectively and saving resource overhead.

[0075] In order to facilitate understanding of the technical solutions of the embodiments of the present application, a brief introduction to the relevant technologies and terms of the present application is first given.

[0076] 1. 5G network architecture:

[0077] The 5G network architecture defined in the 3rd Generation Partnership Project (3GPP) TS23.501 standard is mainly divided into two parts: access network (AN) and core network.

[0078] The access network may include radio access network (RAN) equipment, which is used to implement functions related to wireless access.

[0079] The core network mainly includes the following key logical network elements: access and mobility management function (AMF) network element, session management function (SMF) network element, user plane function (UPF) network element, policy control function (policycontrol function) network element, unified data management function (UDM) network element. In addition, it can also include authentication server function (AUSF) network element, network slice selection function (NSSF) network element, application function (AF) network element, etc.

[0080] See also Figure 1 , which is a schematic diagram of a 5G network architecture. The terminal device may be a user equipment (UE), such as a mobile phone or an IoT terminal device.

[0081] DN is a data network (DN), which is mainly used to provide data transmission services to users, such as Internet protocol (IP) multimedia service (IMS).

[0082] Access network equipment that provides wireless access to users is deployed in RAN, including but not limited to evolved base stations (NodeB or eNB or e-NodeB, evolutionary Node B), wireless fidelity (WiFi) access points (access points, APs), etc.

[0083] The AMF network element is mainly responsible for mobility management in the mobile network, such as user location update, user registration network, user switching, etc.

[0084] The SMF network element is mainly responsible for session management in the mobile network, such as session establishment, modification, and release. Specific functions include allocating IP addresses to users and selecting UPFs that provide message forwarding functions.

[0085] The PCF network element is mainly responsible for providing policies to AMF and SMF, such as quality of service (QoS) policy and slice selection policy.

[0086] The UDM network element is mainly responsible for storing user data, such as contract information and authentication / authorization information.

[0087] The AF network element is mainly responsible for providing service requirements to the 3GPP network, such as affecting service routing and interacting with the PCF network element for policy control.

[0088] The UPF network element is mainly responsible for processing user messages, such as forwarding and billing.

[0089] The terminal device accesses the DN by establishing a protocol data unit (PDU) session (PDU session) between the terminal device to the RAN to the UPF to the DN.

[0090] The AUSF network element is mainly responsible for providing terminal device authentication services for the AMF network element.

[0091] The NSSF network element is mainly responsible for selecting network slices to serve terminal devices.

[0092] In addition, see Figure 1, Nx represents the logical interface or service interface between two network elements, which is used for communication between network elements. For example, N1 is the interface between the terminal device and the AMF network element; N2 is the interface between the access network device and the AMF network element; N3 is the interface between the access network device and the UPF network element; N9 is the interface between different UPF network elements; N6 is the interface between the UPF network element and the DN; N4 is the interface between the UPF network element and the SMF network element; N11 is the interface between the AMF network element and the SMF network element; N7 is the interface between the SMF network element and the PCF network element; N5 is the interface between the PCF network element and the AF network element; N14 is the interface between different AMF network elements; N15 is the interface between the AMF network element and the PCF network element; N22 is the interface between the NSSF network element and the AMF network element; N12 is the interface between the AUSF network element and the AMF network element; N8 is the interface between the UDM network element and the AMF network element; N13 is the interface between the AUSF network element and the UDM network element.

[0093] 2. 5G Qos flow.

[0094] Under the 5G QoS framework, various services will be mapped to QoS flows according to certain rules. After the QoS flow reaches the RAN device, the RAN device will map the QoS flow to the user data bearer (DRB) for transmission.

[0095] 2.1. QoS flow parameters.

[0096] The main parameters of QoS flow include the following:

[0097] 5G service quality identifier (5G QoS identifier, 5QI), address resolution protocol (address resolution protocol, ARP), guaranteed flow bit rate (guaranteed flow bit rate, GFBR) {for GBR type QoS flow}, maximum flow bit rate (maximum flow bit rate, MFBR) {for GBR type QoS flow}, session aggregate maximum bit rate (session-aggregate maximum bit rate, Session-AMBR) {for non-GBR type QoS flow} and terminal device UE-AMBR {for non-GBR type QoS flow}. Among them, Session-AMBR is the maximum bandwidth shared by all non-GBR QoS flows of a PDU session, which is controlled and executed by the UPF network element and the terminal device. UE-AMBR is the maximum bandwidth shared by all non-GBR QoS flows of a terminal device, which is controlled and executed by the RAN device.

[0098] Among them, 5QI includes the following characteristics: resource type: GBR, non-GBR, delay critical GBR; priority; delay budget value; packet error rate; maximum data burst volume (MDBV) (applicable to delay critical GBR services); average window size (applicable to some GBR services).

[0099] Among them, the GBR type is generally used for streaming media services, which have a stable rate, have requirements for latency, and can tolerate a certain degree of packet loss. After admitting GRB services, the network will generally reserve corresponding resources according to the GRB service rate requirements to ensure the transmission rate of terminal devices.

[0100] Among them, the non-GBR type is generally used for web browsing, file transfer protocol (FTP) download and other services. It has no fixed service rate requirements and is not particularly sensitive to latency, but has high requirements for packet loss. The network uses a best-effort scheduling mode outside the GBR reserved resources to provide the transmission rate of the terminal equipment.

[0101] 2.2、Qos flow configuration process

[0102] Figure 2 The diagram shown is a schematic diagram of the Qos flow establishment process, such as Figure 2 As shown, the process of establishing a QoS flow includes:

[0103] S210: The core network device determines that a QoS flow needs to be established.

[0104] like Figure 2 As shown, in a possible implementation, the core network device receives a QoS flow establishment request sent by the terminal device and determines to establish a QoS flow.

[0105] Or, if Figure 2 As shown, in another possible implementation, the core network device receives a QoS flow establishment request sent by the server and determines to establish a QoS flow.

[0106] Another possible implementation manner is that the core network device determines to establish a QoS flow according to the downlink data.

[0107] S220, the core network device sends a QoS flow establishment request to the access network device. Correspondingly, the access network device receives the QoS flow establishment request from the core network device.

[0108] The QoS flow establishment request includes parameters such as 5QI, GFBR, and MFBR.

[0109] S230, the access network device determines to establish a DBR for the QoS flow.

[0110] After the access network device establishes the DBR for the QoS flow, the corresponding relationship between the QoS flow of the uplink data and the DBR may be sent to the terminal device via a radio resource control (RRC) reconfiguration message.

[0111] The corresponding relationship between the QoS flow and DBR of the downlink data is determined and used by the access network equipment itself.

[0112] Among them, the core network device can send a PDU session command to the terminal device, and the PDU session command can include parameters such as 5QI, GFBR, MFBR, and packet filtering rules of the QoS flow, among which the packet filtering rules are the mapping rules between data packets and QoS flows.

[0113] S240, the terminal device sends data.

[0114] Among them, the terminal device can send data to the access network device, and can also send data to the server.

[0115] Specifically, the terminal device distributes the data packets to the corresponding QoS flows according to the data packet filtering rules, and then sends the corresponding QoS flow data to the access network device or server through the corresponding DBR.

[0116] 3. Principle of cloud photo enhancement.

[0117] Usually, after taking a photo locally, the terminal device will process the image locally to meet the requirements for enhancing the image quality. Common image post-processing technologies include: denoising, super-resolution, dark light enhancement, beauty, etc. Some of these processes require a lot of computing power. When the terminal device processes locally, it is limited by the terminal device's processing capabilities. After the processing quality reaches a certain level, it is difficult to improve it.

[0118] In order to meet the requirements for enhanced image quality, one way is for the terminal device to upload the photo to the cloud for processing. A large number of graphic processing units (GPUs) can be deployed on the cloud to perform image processing. In this way, the quality of the processed image is better than that of the local one. The specific process can be: after the terminal device takes the photo, it uploads the photo to the cloud. After the cloud processes the photo, it returns the photo to the local computer and displays it to the terminal device locally.

A person of ordinary skill in the art can know that with the evolution of network architecture and the emergence of new business scenarios, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

The chip system can be composed of chips, or can include chips and other discrete devices. The embodiments of the present application do not specifically limit this.

[0132] It is understandable that the above functions can be network elements in hardware devices, software functions running on dedicated hardware, or a combination of hardware and software, or virtualized functions instantiated on a platform (e.g., a cloud platform).

Figure 4 FIG. 4 is a schematic diagram of the structure of a communication device 400 provided in an embodiment of the present application. The communication device 400 includes one or more processors 401, a communication line 402, and at least one communication interface ( Figure 4 The example in which the communication interface 404 and a processor 401 are included is merely exemplary), and a memory 403 may also be included optionally.

The memory may exist independently and be connected to the processor via a communication line 402. The memory may also be integrated with the processor.

[0138] The memory 403 is used to store computer-executable instructions for executing the solution of the present application, and the execution is controlled by the processor 401. The processor 401 is used to execute the computer-executable instructions stored in the memory 403, thereby realizing the transmission method provided in the embodiment of the present application.

[0139] Alternatively, optionally, in an embodiment of the present application, the processor 401 may also perform processing-related functions in the transmission method provided in the following embodiments of the present application, and the communication interface 404 is responsible for communicating with other devices or communication networks, which is not specifically limited in the embodiments of the present application.

[0140] Optionally, the computer-executable instructions in the embodiments of the present application may also be referred to as application code, which is not specifically limited in the embodiments of the present application.

[0146] Combine the following Figure 3 The communication system shown describes the transmission method provided in the embodiment of the present application.

[0147] It should be noted that in the following embodiments of the present application, the message names between network elements, the names of parameters, or the names of information are only examples. In other embodiments, they may also be other names, and the method provided in the present application does not make any specific limitations on this.

[0148] It is understandable that in the embodiment of the present application, each network element may perform some or all of the steps in the embodiment of the present application, and these steps or operations are only examples. The embodiment of the present application may also perform other operations or variations of various operations. In addition, each step may be performed in a different order presented in the embodiment of the present application, and it is possible that not all operations in the embodiment of the present application need to be performed.

[0149] In a possible implementation, the terminal device is used to send a request message to the access network device, and the request message is used to transmit the processing capability of the target service. The access network device is used to receive the request message from the terminal device and send a resource response message to the terminal device, and the resource response message is used to indicate the second data volume information, and the second data volume information is used to indicate the processing capability of the target service supported by the access network device for transmission within the first time delay, and the processing capability includes the data volume or the data transmission rate. The terminal device is used to receive the resource response message from the access network device and send the data of the target service to the access network device according to the second data volume information. The scheme will be described in detail below in combination with several specific embodiments.

[0150] Figure 5 It is a schematic diagram of an example of the transmission method provided in the embodiment of the present application. The method is explained by taking the interaction between a terminal device and an access network device as an example. Of course, the subject that executes the terminal device action in the method can also be a device / module in the terminal device, such as a chip, processor, processing unit, etc. in the terminal device; the subject that executes the access network device action in the method can also be a device / module in the access network device, such as a chip, processor, processing unit, etc. in the access network device, and the embodiment of the present application does not make specific limitations on this. For example, Figure 5 As shown, the transmission method 500 includes:

[0151] S510: The terminal device sends a request message to the access network device. Correspondingly, the access network device receives the request message from the terminal device.

[0152] In the embodiment of the present application, the request message is used to request the processing capability of the transmission target service.

[0153] Exemplarily, the target service in the embodiment of the present application may be a cloud-based photo transmission service.

[0154] In the embodiment of the present application, the processing capability includes data volume or data transmission rate.

[0155] In the embodiment of the present application, the request message includes first data volume information and first delay indication information. The first data volume information is used to indicate the processing capability of the target service requested by the terminal device to be transmitted within the first delay.

[0156] Optionally, the data volume of the embodiments of the present application, such as the data volume of the target service, can be a data volume range or a specific data volume value. The data transmission rate of the embodiments of the present application indicates the data rate (the amount of data transmitted per second), which is uniformly described here and the present application does not limit this.

[0157] In a possible implementation, the first data volume information is used to indicate the data volume of the target service requested by the terminal device to be transmitted within the first time delay.

[0158] For example, the data volume indicated by the first data volume information may be 30Mbits to 300Mbits, or the data volume indicated by the first data volume information may also be 100Mbits.

[0159] Optionally, the delay in the embodiment of the present application, such as the first delay, indicates the time taken to transmit data of a target service of a specific data volume.

[0160] For example, the first delay is 2 seconds, which is used to indicate that the time used to transmit the data of the target service of 100 Mbit is 2 seconds.

[0161] In another possible implementation, the first data volume information is used to indicate the data transmission rate of the target service requested by the terminal device to be transmitted within the first delay, that is, the product of the data transmission rate and the first delay represents the amount of data requested by the terminal device to be transmitted within the first delay.

[0162] Optionally, the data transmission rate in the embodiment of the present application may indicate the amount of data transmitted per second, for example, 50M bits per second (BPS).

[0163] Optionally, the delay in the embodiment of the present application, such as the first delay, indicates the time for transmitting data of the target service at a specific rate.

[0164] For example, the first delay is 2s, which is used to indicate that the data volume indicated by the first data volume information is transmitted at a rate of 50MBPS in 2 seconds, and the data volume indicated by the first data volume information is 100Mbits.

[0165] In other words, in this implementation, the content indicated by the first data volume information can indicate a transmission time, such as 2s, and the size of the data volume requested to be transmitted within the transmission time. Specifically, the purpose of information transmission can be achieved by indicating the first delay and data volume, or indicating the first delay and data transmission rate. In addition, the indication of data volume or transmission rate can be a specific value or a range. For example, when indicating data volume, it can indicate 100Mbits, or 30Mbits to 300M bits; when indicating transmission rate, it can indicate 50M bits / second, or 15M bits / second to 150M bits / second. This application does not limit this.

[0166] Exemplarily, the request message in the embodiment of the present application can be sent via a MAC CE message, or physical layer signaling, or a radio link control (radio link control, RLC) packet, or a packet data convergence layer protocol (packet data convergence protocol, PDCP) control packet, or an RRC command, and the present application does not limit this.

[0167] Optionally, the request message in the embodiment of the present application may also include the estimated arrival time information of the target service. Among them, in one possible implementation, the estimated arrival time information of the target service is used to indicate that the estimated arrival time of the target service is the time difference between the time when the actual data arrives at the access layer of the terminal device and the time when the terminal device sends the request message.

[0168] It should be understood that after sending the request message, the terminal device still needs processing time to generate a data packet that can actually be sent. For example, if the estimated arrival time information of the target service indicates that the actual data arrives at the access layer of the terminal device at the 7th second, and the terminal device sends the resource request at the 6th second, then the access network device can start receiving the data of the target service from the 7th second, thus saving 1 second of resource overhead.

[0169] In other words, carrying the estimated arrival time information of the target service in the request message can make the access network device allocate resources to the target service more accurately, thus saving resource overhead.

[0170] Optionally, the request message in the embodiment of the present application may also carry the DRB ID or logical channel ID or Qos flow ID corresponding to the DRB established by the access network device for the terminal device, and the embodiment of the present application does not make any specific limitations on this.

[0171] Optionally, if the terminal device triggers a service request, for example, the terminal device's App triggers a request to send a photo, the terminal device can send a resource request indication to the access network device, and the access network device can feedback the amount of data that can be transmitted to the terminal device based on the resource status. This process can be performed once in each service processing, for example, in each photo processing process.

[0172] S520, the access network device sends a resource response message to the terminal device. Correspondingly, the terminal device receives the resource response message from the access network device.

[0173] In one embodiment, the resource response message is used to indicate the second data volume information, and the second data volume information is used to indicate the processing capability of the access network device supporting the transmission of the target service within the first time delay.

[0174] Referring to the description of the first data volume information above, optionally, the second data volume information is used to indicate the data volume of the target service supported for transmission by the access network device within the first time delay, and the data volume may be a data volume range or a specific data volume value. For example, the data volume indicated by the second data volume information may be 30Mbits to 100M bits, or the data volume indicated by the second data volume information may be 100Mbit. Optionally, the second data volume information is used to indicate the data transmission rate of the target service supported for transmission by the access network device within the first time delay, for example, 40MBPS.

[0175] In the embodiment of the present application, the second data volume information is determined by the access network device according to the first data volume information. Exemplarily, the data volume indicated by the first data volume information is 300 Mbits, and the data volume indicated by the second data volume information may be 100 Mbits.

[0176] In a possible implementation, the resource response message includes the second data volume information. Exemplarily, the second data volume information included in the resource response message indicates a data volume of 100 MBits.

[0177] In another possible implementation, the resource response message does not carry data volume information, and the resource response message includes indication information for indicating that the processing capability of the access network device supporting the transmission of the target service is the processing capability indicated by the first data volume information.

[0178] For example, the data volume indicated by the first data volume information is 30Mbits to 300M bits, and the resource response message includes indication information, indicating that the data volume of the target service supported by the access network device for transmission is 30Mbits to 300M bits, or indicating that the maximum data volume of the target service supported by the access network device for transmission is 300M bits.

[0179] Of course, the above is only an exemplary implementation of a default signaling or indication. The signaling or indication in the resource response message may also include other content, and the embodiments of the present application do not specifically limit this.

[0180] Exemplarily, the resource response message in the embodiment of the present application can be sent via a MAC CE message, or physical signaling, or an RLC control packet, or a PDCP control packet, or an RRC command, and the present application does not limit this.

[0181] Optionally, the resource response message in the embodiment of the present application may also include parameters such as the DRB identification ID corresponding to the request message, or the logical channel (logical channel, LCH) ID, or the Qos flow ID. The description of the relevant parameters can refer to the prior art and will not be repeated here.

[0182] Optionally, the resource response message in the embodiment of the present application may also include a second initial transmission rate, which is used to determine the sending window of the application transmission protocol for the data of the target service, so that the terminal device can send the data of the target service to the access network device according to the second initial transmission rate, thereby saving the overhead of the terminal device attempting the transmission rate multiple times.

[0183] Exemplarily, the second initial transmission rate in the embodiment of the present application may be the initial transmission rate of the MAC CE adaptation rate.

[0184] Exemplarily, the application transmission protocol in the embodiments of the present application may be the transmission control protocol (TCP) or a low-latency Internet transport layer protocol (quick UDP internet connection, QUIC) based on the user datagram protocol (UDP).

[0185] In another embodiment, the resource response message indicates that the access network device cannot provide the processing capability of the target service. Exemplarily, the resource response message may include a failure indication, which is used to indicate that the access network device cannot provide the processing capability of the target service.

[0186] For example, the resource response message is a failure response message, which is used to indicate that the access network device cannot provide the processing capability of the target service.

[0187] It should be noted that, when the resource response message indicates that the access network device cannot provide the processing capability of the target service, the following step S530 is not performed. After receiving the resource response message, the terminal device determines that it will not send the data of the target service to the access network device. In one possible implementation, the local application layer of the terminal device processes the data of the target service, that is, the terminal device sends the data of the target service to the access network device in order to allow the access network device to process the data of the target service. At this time, the terminal device does not send the data of the target service to the access network device, and the local application layer of the terminal device processes the target service.

[0188] Optionally, the resource response message in the embodiment of the present application may be a reused existing message, in which a new field for indicating the second data volume information is newly added or a new field for indicating that the access network device is unable to provide the processing capability of the target service is newly added; or, the resource response message in the embodiment of the present application may be a newly added message, in which the second data volume information is separately indicated, or, in which the newly added message is separately indicated that the access network device is unable to provide the processing capability of the target service; for example, the resource response message is a failure response message, in which an access network device is unable to provide the processing capability of the target service, and the embodiment of the present application does not make any specific limitation on this.

[0189] Optionally, in an embodiment of the present application, a message for indicating the second data volume information and a message for indicating that the access network device cannot provide the processing capability of the target service may use the same signaling format, such as by setting different values ​​of fields in the same MAC CE to indicate different response results, such as setting the data burst max size to 0 or to the second data volume information. Alternatively, in an embodiment of the present application, a message for indicating the second data volume information and a message for indicating that the access network device cannot provide the processing capability of the target service may use different signaling formats, such as using MAC CE1 to indicate the second data volume information in a message for indicating the second data volume information, and using MAC-CE2 to indicate that the access network device cannot provide the processing capability of the target service. The embodiment of the present application does not specifically limit this.

[0190] In the embodiments of this application, the following will be described Figure 6 or Figure 7 In the corresponding transmission method, the case where the resource response message indicates that the access network device cannot provide the processing capability of the target service is not described in detail, but it should be understood that the present application implements the example Figure 6 or Figure 7 This situation is included in the corresponding transmission method and is explained here uniformly.

[0191] S530: The terminal device sends data of the target service to the access network device according to the second data volume information.

[0192] Correspondingly, the access network device receives data of the target service from the terminal device.

[0193] Optionally, in an embodiment of the present application, after receiving the resource response message, the terminal device may also determine parameters of the target service based on the second data volume information indicated in the resource response message.

[0194] For example, in the embodiment of the present application, the parameter of the target service may be resolution, compression rate, etc. For example, if the range of the data volume indicated by the second data volume information is small, the terminal device will reduce the resolution of the sent picture, or reduce the number of pictures, or increase the compression rate to send subsequent data, so as to meet the first delay requirement of data transmission.

[0195] Furthermore, in S503, the terminal device sends the target service data to the access network device according to the second data volume information, which may include: S503a or S503b.

[0196] S503a: When the data volume indicated by the second data volume information is greater than or equal to the first threshold, the terminal device may send data of the target service to the access network device according to the parameters of the target service.

[0197] S503b, when the data volume indicated by the second data volume information is less than the first threshold, the terminal device does not send the target service data to the access network device. That is, when the second data volume information is less than the data volume required by the terminal device, the terminal device chooses not to send the target service to the access network device.

[0198] Optionally, in an embodiment of the present application, the first threshold may be a data volume corresponding to the target service.

[0199] Exemplarily, the data volume indicated by the second data volume information is 100 Mbits, and the first threshold is 70 Mbits. The terminal device can send 70 Mbits of target service data with a resolution of 1024×768 to the access network device based on the resolution of the target service being 1024×768.

[0200] Or, exemplarily, the data volume indicated by the second data volume information is 60 Mbits, and the first threshold is 70 Mbits. The terminal device may not send 70 Mbits of target service data to the access network device according to the 60 Mbits indicated in the resource response message.

[0201] In the transmission method provided by the embodiment of the present application, when the target service arrives, the terminal device can directly carry the first data volume information and the indication information of the first delay in the request message to request the processing capacity for transmitting the target service. Furthermore, the access network device determines the second data volume information used to indicate the processing capacity of the target service supported by the access network device within the first delay, and feeds back the second data volume information to the terminal device, so that the terminal device sends the data of the target service to the access network device according to the second data volume information. Among them, the second data volume information is determined according to the first data volume information indicating the processing capacity of the target service requested to be transmitted within the first delay. On the one hand, since the scheme is initiated when the target service arrives, the overhead of reserving resources in advance before the service arrives is saved. On the other hand, since the terminal device sends the data of the target service according to the second data volume information fed back by the access network device, and the second data volume information is determined according to the first data volume information fed back by the terminal device for indicating the processing capacity of the target service requested to be transmitted within the first delay, the scheme can ensure the transmission rate of the target service.

[0202] Figures 6 to 9 These are several other schematic diagrams of the transmission method provided in the embodiments of the present application, which are described below.

[0203] In one possible implementation, Figure 6 As shown, it is a schematic diagram of an example of the transmission method provided in an embodiment of the present application. The method is explained by taking the interaction among a terminal device, an access network device and a core network device as an example. Of course, the subject that executes the terminal device action in the method may also be a device / module in the terminal device, such as a chip, a processor, a processing unit, etc. in the terminal device; the subject that executes the access network device action in the method may also be a device / module in the access network device, such as a chip, a processor, a processing unit, etc. in the access network device; the subject that executes the core network device action in the method may also be a device / module in the core network device, such as a chip, a processor, a processing unit, etc. in the core network device, and the embodiment of the present application does not make specific limitations on this. For example, Figure 6 As shown, the transmission method 600 includes:

[0204] S610: The core network device sends a second request message to the access network device. Correspondingly, the access network device receives the second request message from the core network device.

[0205] In an embodiment of the present application, the steps performed by the core network device may be performed by, for example, AMF, and this embodiment of the present application is not limited to this.

[0206] In an embodiment of the present application, the second request message is used to request the establishment of a QoS flow that carries the target service. Among them, the second request message includes the first data volume information and the indication information of the first delay. For the relevant introduction of the first data volume information and the indication information of the first delay, please refer to the description of step S510 in method 500. The only difference is that the first data volume information in the embodiment of the present application is used to indicate the core network device to indicate the processing capability of the target service transmitted within the first delay, which will not be repeated here. In an embodiment of the present application, a QoS flow is a channel resource used to indicate the transmission of data packets with the same or similar QoS requirements. In an embodiment of the present application, a QoS flow may also be other names, such as a service flow, or for example, a bearer, or for example, a service pipeline, etc., which is not limited in the embodiment of the present application.

[0207] Exemplarily, the second request message may be included in a protocol data unit (PDU) session establishment message, or the second request message may be included in a PDU session modification message, or the second request message may be included in a terminal device context establishment message, or the second request message may be included in a terminal device context modification message, and the present application does not limit this.

[0208] Exemplarily, in an embodiment of the present application, the QoS flow carrying the target service may be a GBR type QoS flow, or may be a non-GBR type QoS flow, or may be a new type of QoS flow such as a burst type QoS flow, or may be an on-demand guaranteed type QoS flow, etc. The embodiment of the present application is not limited to this.

[0209] In a possible implementation, the core network device may determine the second request message through the uplink and downlink data, such as the protocol (internet protocol, IP) address, port number, or application (application, APP) ID of the connection between network devices.

[0210] In another possible implementation, the core network device receives a first request message from the terminal device, wherein the first request message includes first data volume information and first delay indication information, and the core network device determines the second request message based on the first request message. Exemplarily, the first request message may be included in a PDU session establishment message, or the first request message may be included in a PDU session modification message, which is not limited in this application.

[0211] In another possible implementation, the core network device receives a third request message from the server, wherein the third request message includes the first data volume information and the indication information of the first delay, and the core network device determines the second request message according to the third request message. Exemplarily, the third request message may be included in a resource application message, or in a PDU session establishment message, or the third request message may be included in a PDU session modification message, which is not limited in this application.

[0212] In the embodiment of the present application, the first request message or the third request message is triggered by the target service. In other words, when the target service arrives, the terminal device can be triggered to send the first request message to the core network device or the server can be triggered to send the third request message to the core network device, and the embodiment of the present application does not make specific limitations on this.

[0213] S620: The access network device sends a second response message to the core network device. Correspondingly, the core network device receives the second response message from the access network device.

[0214] In the embodiment of the present application, the second response message is used to indicate that the QoS flow carrying the target service is successfully established.

[0215] Optionally, in an embodiment of the present application, the second response message may be in a PDU session establishment message response, or the second response message may be included in a PDU session modification response message, or the second response message may be included in a UEcontext establishment response message, or the second response message may be included in a UE context modification response message, and the present application does not limit this.

[0216] S630: The access network device sends a first configuration message to the terminal device. Correspondingly, the terminal device receives the first configuration message from the access network device.

[0217] In an embodiment of the present application, the first configuration message is used to indicate the establishment of a data bearer of a QoS flow carrying a target service. The first configuration message may include a first initial transmission rate, and the first initial transmission rate indicates the initial rate at which data of the target service is sent to the access network device. It should be understood that when the resource response message includes a second initial transmission rate and the first configuration message includes the first initial transmission rate, the first initial transmission rate and the second initial transmission rate are the same initial transmission rate.

[0218] In one possible implementation, the first configuration message includes first data volume information and / or first delay indication information, and then the terminal device can determine the initial data volume of the target service that can be transmitted based on the first data volume information and / or the first delay indication information.

[0219] Optionally, in an embodiment of the present application, the first data volume information and / or the indication information of the first delay in the first configuration message may be included in the 5QI parameter of the Qos flow and sent to the terminal device; or, the first data volume information and / or the indication information of the first delay in the first configuration message may be included in other parameters independent of 5QI and sent to the terminal device. The embodiment of the present application does not make specific limitations on this.

[0220] In another possible implementation, the first configuration message does not include the first data volume information, and the terminal device defaults to carrying the data bearer of the QoS flow of the target service as the data bearer of the QoS flow corresponding to the first data volume information.

[0221] Optionally, in an embodiment of the present application, the first configuration message may be included in an RRC reconfiguration message, which is not limited in the present application.

[0222] Optionally, in an embodiment of the present application, the content of the first configuration message may be the same as the content of the second response message; or, the content of the first configuration message may be different from the content of the second response message, in which case the first configuration message may be determined by the second response message.

[0223] S640, the core network device sends a second configuration message to the terminal device. Correspondingly, the terminal device receives the second configuration message from the core network device.

[0224] In the embodiment of the present application, the second configuration message is used to instruct the establishment of a QoS flow that carries the target service.

[0225] In a possible implementation, the second configuration message includes first data volume information and indication information of the first delay, and then the terminal device determines that the QoS flow carrying the target service is the QoS flow corresponding to the first data volume information.

[0226] Optionally, in an embodiment of the present application, the first data volume information and the indication information of the first delay in the second configuration message may be included in the 5QI parameter of the Qos flow and sent to the terminal device. For example, as shown in Table 1, the first data volume information and the indication information of the first delay of the newly established QoS flow in an embodiment of the present application are included in the parameters of the 5QI;

[0227] Table 1

[0228] QoS flow type - (GBR or Non GBR) 5G Service Quality Indicator (5QI) Address Resolution Protocol (ARP) Burst size range Latency

[0229] Alternatively, the first data volume information and the first delay indication information in the second configuration message are included in other parameters independent of 5QI and sent to the terminal device. For example, as shown in Table 2, the first data volume information and the first delay indication information of the newly established QoS flow in an embodiment of the present application are included in other parameters that are independent of 5QI.

[0230] Table 2

[0231]

[0232]

[0233] Optionally, in an embodiment of the present application, the second configuration message may be included in a PDU session establishment message, or the second configuration message may also be included in a PDU session modification message, or the second configuration message may be included in a UE context establishment message, or the second configuration message may be included in a UE context modification message, and the present application does not limit this.

[0234] Optionally, in an embodiment of the present application, the first data volume information and the indication information of the first delay included in the second configuration message may be the same as the content of the second response message; or, the first data volume information and the indication information of the first delay included in the second configuration message may be different from the content of the second response message, in which case the second configuration message may be determined by the second response message.

[0235] Through the above steps S610-S640, the QoS flow carrying the target service is established. Further, the terminal device can send a request message to the access network device according to the relevant information of the QoS flow of the target service. Figure 6 As shown, the transmission method provided in the embodiment of the present application may also include the following steps:

[0236] S650, the terminal device sends a request message to the access network device. Correspondingly, the access network device receives the request message from the terminal device. The request message is used to request the processing capability of the target service to be transmitted.

[0237] The relevant description of step S650 is Figure 5 The step S510 in the embodiment described is similar, the only difference is that in step S650, since the access network device has obtained the first data volume information and the indication information of the first delay through the core network, the request message may not include the first data volume information and the indication information of the first delay, and the rest of the related descriptions can refer to Figure 5 The description of step S510 in the embodiment is not repeated here.

[0238] S660, the access network device sends a resource response message to the terminal device. Correspondingly, the terminal device receives the resource response message from the access network device.

[0239] For the description of step S660, please refer to Figure 5 The relevant description of step S520 in the embodiment is not repeated here.

[0240] S670: The terminal device sends data of the target service to the access network device according to the second data volume information.

[0241] Correspondingly, the access network device receives data of the target service from the terminal device.

[0242] For the description of step S670, please refer to Figure 5 The relevant description of step S530 in the embodiment is not repeated here.

[0243] The transmission method provided in the embodiment of the present application triggers a new QoS flow when the target service arrives. In the establishment request of the QoS flow, the core network device sends the first data volume information and the indication information of the first delay for establishing the QoS flow to the access network device, so that the access network device establishes a QoS flow dedicated to the target service according to the first data volume information and the indication information of the first delay. Further, after the QoS flow is established, the terminal device can request the processing capacity for transmitting the target service. Furthermore, the access network device can determine the second data volume information for indicating the data volume of the target service supported by the access network device within the first delay according to the parameters of the QoS flow of the target service (i.e., the first data volume information and the indication information of the first delay), and then feedback the second data volume information to the terminal device, so that the terminal device sends the data of the target service to the access network device according to the second data volume information. On the one hand, since the scheme is initiated when the target service arrives, it saves the overhead of reserving resources in advance before the service arrives. On the other hand, since the terminal device sends the data of the target service based on the second data volume information fed back by the access network device, and the second data volume information is determined by the first data volume information (i.e., the parameters of the QoS flow) used to indicate the processing capacity of the target service requested by the core network device to be transmitted within the first time delay during the process of the core network device requesting to establish a QoS flow, this solution can ensure the transmission rate of the target service.

[0244] In another possible implementation, Figure 7 As shown, it is a schematic diagram of an example of the transmission method provided in an embodiment of the present application. The method is explained by taking the interaction among a terminal device, an access network device and a core network device as an example. Of course, the subject that executes the terminal device action in the method may also be a device / module in the terminal device, such as a chip, a processor, a processing unit, etc. in the terminal device; the subject that executes the access network device action in the method may also be a device / module in the access network device, such as a chip, a processor, a processing unit, etc. in the access network device; the subject that executes the core network device action in the method may also be a device / module in the core network device, such as a chip, a processor, a processing unit, etc. in the core network device, and the embodiment of the present application does not make specific limitations on this. For example, Figure 7 As shown, the transmission method 700 includes:

[0245] S710: The core network device sends a fourth request message to the access network device. Correspondingly, the access network device receives the fourth request message from the core network device.

[0246] In the embodiment of the present application, the fourth request message is used to request the establishment of a QoS flow carrying the target service. The fourth request message includes the third data volume information and the first delay. The third data volume information in the embodiment of the present application is used by the access network device to determine the first data volume information. The embodiment of the present application will be described in step S720.

[0247] Exemplarily, the fourth request message may be included in a PDU session establishment message, or the fourth request message may be included in a PDU session modification message, or the fourth request message may be included in a terminal device context establishment message, or the fourth request message may be included in a terminal device context modification message, and this application does not limit this.

[0248] Exemplarily, in an embodiment of the present application, the QoS flow carrying the target service may be a QoS flow of the GBR type, or may be a QoS flow of the non-GBR type, or may be a new type of QoS flow, which is not limited in the embodiment of the present application. QoS flow is a channel resource used to indicate the transmission of data packets with the same or similar QoS requirements, and may also be other names such as service flow, bearer, service pipeline, etc., which is not limited in the embodiment of the present application.

[0249] In a possible implementation, the core network device may determine the fourth request message through, for example, an IP address, a port number, or an APP ID in the uplink and downlink data.

[0250] In another possible implementation, the core network device receives a first request message from the terminal device, wherein the first request message includes third data volume information and first delay indication information, and the core network device determines a fourth request message based on the first request message. Exemplarily, the first request message may be included in a PDU session establishment message, or the first request message may be included in a PDU session modification message, which is not limited in this application.

[0251] In another possible implementation, the core network device receives a third request message from the server, wherein the third request message includes third data volume information and indication information of the first delay, and the core network device determines a fourth request message based on the third request message. Exemplarily, the third request message may be included in a PDU session establishment message, or the third request message may be included in a PDU session modification message, which is not limited in this application.

[0252] In the embodiment of the present application, the first request message or the third request message is triggered by the target service. In other words, when the target service arrives, the terminal device can be triggered to send the first request message to the core network device or the server can be triggered to send the third request message to the core network device, and the embodiment of the present application does not make specific limitations on this.

[0253] S720, the access network device sends a fourth response message to the core network device. Correspondingly, the core network receives the second response message from the access network.

[0254] In the embodiment of the present application, the fourth response message is used to indicate that the QoS flow carrying the target service is successfully established.

[0255] In an embodiment of the present application, the fourth response message includes first data volume information, and the first data volume information is determined by the access network device according to the third data volume information in the fourth request message and its own actual situation. The processing capacity indicated by the first data volume information may be lower than or equal to the processing capacity indicated by the third data volume information. For example, the data volume indicated by the third data volume information may be 300Mbits, and the access network device determines that it cannot accept the data volume indicated by the third data volume information based on its own capacity. In this case, the access network device determines that the data volume indicated by the first data volume information may be 200Mbits based on its own capacity. Alternatively, the data volume indicated by the third data volume information may be 300Mbits, and the access network device determines that it can accept the data volume indicated by the third data volume information based on its own capacity. In this case, the access network device determines that the data volume indicated by the first data volume information may be 300Mbits based on its own capacity.

[0256] It should be understood that in the embodiment of the present application, the first data volume information is determined by the access network device based on the third data volume information sent by the core network device. Therefore, the first data volume information is used to indicate the processing capacity of the access network device to allow the target service to be transmitted within the first delay.

[0257] Optionally, in an embodiment of the present application, the fourth response message may be included in a PDU session establishment message, or the fourth response message may be included in a PDU session modification message, or the fourth response message may be included in a UE context establishment message, or the fourth response message may be included in a UE context modification message, and the present application does not limit this.

[0258] S730, the access network device sends a first configuration message to the terminal device. Correspondingly, the terminal device receives the first configuration message from the access network device.

[0259] The relevant description of step S730 can be found in Figure 6 The relevant description of step S630 in the embodiment is not repeated here.

[0260] S740, the core network device sends a second configuration message to the terminal device. Correspondingly, the terminal device receives the second configuration message from the core network device.

[0261] For the description of step S740, please refer to Figure 6 The relevant description of step S640 in the embodiment is not repeated here.

[0262] It should be noted that in step S730 and step S740, at least one of the first configuration information and the second configuration information includes the first data volume information, and then the terminal device determines that the QoS flow carrying the target service is the QoS flow corresponding to the first data volume information, or the terminal device determines that the data bearer of the QoS flow carrying the target service is the QoS data bearer corresponding to the first data volume information.

[0263] Through the above steps S710-S740, the QoS flow carrying the target service is established. Further, the terminal device can send a request message to the access network device according to the relevant information of the QoS flow of the target service. Figure 7 As shown, the transmission method provided in the embodiment of the present application may also include the following steps:

[0264] S750, the terminal device sends a request message to the access network device. Correspondingly, the access network device receives the request message from the terminal device. The request message is used to request the processing capability of the transmission target service.

[0265] For the description of step S750, please refer to Figure 6 The relevant description of step S650 in the embodiment is not repeated here.

[0266] S760, the access network device sends a resource response message to the terminal device. Correspondingly, the terminal device receives the resource response message from the access network device.

[0267] For the description of step S760, please refer to Figure 5 The relevant description of step S520 in the embodiment is not repeated here.

[0268] S770, the terminal device sends the data of the target service to the access network device according to the second data volume information.

[0269] For the description of step S770, please refer to Figure 5 The relevant description of step S530 in the embodiment is not repeated here.

[0270] Exemplarily, in an embodiment of the present application, the third data volume information requested by the terminal device or server may be, for example, 300Mbits, and the first data volume information determined by the access network device may be, for example, 200Mbits. In actual scheduling, the second data volume information indicated by the access network device to the terminal device may be, for example, 100Mbits, and the terminal device may send the target service data to the access network device according to the second data volume information.

[0271] The transmission method provided by the embodiment of the present application triggers a new QoS flow when the target service arrives. In the establishment request of the QoS flow, the core network device sends the third data volume information and the first delay of the parameters used to establish the QoS flow to the access network device, so that the access network device determines the first data volume information and the indication information of the first delay that it can accept according to the third data volume information and the indication information of the first delay, and establishes a QoS flow dedicated to the target service. Further, after the QoS flow is established, the terminal device can request the processing capacity for transmitting the target service. Furthermore, the access network device can determine the second data volume information used to indicate the processing capacity of the target service supported by the access network device within the first delay according to the parameters of the QoS flow of the target service (i.e., the first data volume information and the indication information of the first delay), and then feedback the second data volume information to the terminal device, so that the terminal device sends the data of the target service to the access network device according to the second data volume information. On the one hand, since the scheme is initiated when the target service arrives, it saves the overhead of reserving resources in advance before the service arrives. On the other hand, since the terminal device sends the data of the target service based on the second data volume information fed back by the access network device, and the second data volume information is determined by the first data volume information (i.e., the parameters of the QoS flow) used to indicate the processing capacity of the target service requested by the core network device to be transmitted within the first time delay during the process of the core network device requesting to establish a QoS flow, this solution can ensure the transmission rate of the target service.

[0272] Figure 8 FIG. 4 is a schematic diagram of the internal interaction of the terminal device during the process of establishing the QoS flow of the target service in the above embodiment. Figure 8 As shown, the terminal device includes an APP of the terminal device and a modulation and demodulation module modem of the terminal device. The steps performed by the terminal device in the above embodiment can be performed by a module or chip of the terminal device, for example, a modem of the terminal device. Figure 8 As shown, the transmission method provided in the embodiment of the present application also includes:

[0273] S810, the APP sends a fifth request message to the modem. Correspondingly, the modem receives the fifth request message from the APP.

[0274] In the embodiment of the present application, the fifth request message is used to request the establishment of a QoS flow that carries the target service.

[0275] S820: The modem sends first bandwidth information to the APP. Correspondingly, the APP receives the bandwidth information from the modem.

[0276] In an embodiment of the present application, after the modem receives the first configuration message from the access network device and the second configuration message from the core network device, it can send the first bandwidth information to the APP. The first bandwidth information may include the initial bandwidth information of the uplink and downlink, and the first data volume information corresponding to the QoS flow of the target service.

[0277] Optionally, in the embodiment of the present application, after receiving the first bandwidth information, the APP may also send data of the target service to the server according to the first bandwidth information.

[0278] Figure 8 In the method shown, the APP sends a fifth request message to the modem requesting the establishment of a QoS flow for carrying the target service. After receiving the fifth request message, the modem interacts with the core network device and the access network device to establish a QoS flow for carrying the target service. Further, the modem determines that the QoS flow carrying the target service is successfully established, and sends the first bandwidth information related to the QoS flow carrying the target service to the APP, so that the APP obtains the first bandwidth information, and then sends the data of the target service to the server according to the first bandwidth information.

[0279] Fig. 9 1 is a schematic diagram of the internal interaction of the terminal device after the terminal device initiates a resource request in the above embodiment. The terminal device includes an APP of the terminal device and a modem of the terminal device. The steps executed by the terminal device in the above embodiment may be executed by a module or chip of the terminal device, for example, the modem of the terminal device. Fig. 9 As shown, the transmission method provided in the embodiment of the present application also includes: modem.

[0280] S910, the APP sends a sixth request message to the modem, and correspondingly, the modem receives the sixth request message from the APP.

[0281] In the embodiment of the present application, the sixth request message is used to request the processing capability of the target service, and the modem sends a request message to the access network device according to the sixth request message.

[0282] In a possible implementation, the target service does not trigger the creation of a new QoS flow, and the modem triggers the following after receiving the sixth request message: Figure 5 The corresponding process on the terminal device side is shown.

[0283] In another possible implementation, the target service triggers a new QoS flow, and before the APP sends the sixth request message to the modem, the following is also included: Figure 8 The steps in the method shown.

[0284] S920, the modem sends a first response message to the APP, and correspondingly, the APP receives the first response message from the modem.

[0286] S930, the APP determines the parameters of the target service through the first response message, and sends the data of the target service to the modem according to the parameters of the target service.

[0289] Above Figures 5 to 9 The embodiment shown describes the transmission method provided by the embodiment of the present application in a specific implementation manner. In summary, Fig.10 The schematic diagram of the general flow of the transmission method provided in the embodiment of the present application is as follows:

[0290] S1010: The terminal device sends a request message to the access network device. Correspondingly, the access network device receives the request message from the terminal device.

[0291] In the embodiment of the present application, the request message is used to request the processing capability of the transmission target service.

[0292] Optionally, in an embodiment of the present application, the processing capacity of the target service is the processing capacity of the target service that the access network device allows to be transmitted within the first time delay.

[0293] In one possible implementation, the request message includes first data volume information and first delay indication information, and the first data volume information is used to indicate the processing capability of the target service requested by the terminal device to be transmitted within the first delay. The relevant description of the request message including the first data volume information and the first delay indication information in the embodiment of the present application can be referred to. Figure 5 The relevant description of the embodiments of the present invention will not be repeated here.

[0294] In another possible implementation, the target service triggers a new QoS flow, and the request message does not need to include the first data volume information and the indication information of the first delay. The first data volume information is used to indicate the processing capability of the target service requested by the core network device to be transmitted within the first delay, or the first data volume information is used to indicate the processing capability of the target service allowed to be transmitted within the first delay by the access network device. The relevant description of the target service triggering the new QoS flow in the embodiment of the present application can be referred to. Figure 6 or Figure 7 The relevant description of the embodiments of the present invention will not be repeated here.

[0295] S1020, the access network device sends a resource response message to the terminal device. Correspondingly, the terminal device receives the resource response message from the access network device.

[0296] In the embodiment of the present application, the resource response message is used to indicate the second data volume information. Figure 5 to Figure 7 The relevant description in the embodiments of the present invention will not be repeated here.

[0297] S1030: The terminal device sends the target service data to the access network device according to the second data volume information. Correspondingly, the access network device receives the target service data from the terminal device.

[0298] In the embodiment of the present application, step S1030 can refer to Figure 5 to Figure 7 The relevant description in the embodiments of the present invention will not be repeated here.

[0299] In the transmission method provided by the embodiment of the present application, when the target service arrives, the terminal device requests the processing capacity for transmitting the target service. Then, the access network device feeds back the second data volume information to the terminal device, so that the terminal device sends the data of the target service to the access network device according to the second data volume information. On the one hand, since the scheme is initiated when the target service arrives, the overhead of reserving resources in advance before the service arrives is saved. On the other hand, since the terminal device sends the data of the target service according to the second data volume information fed back by the access network device, and the second data volume information is determined according to the first data volume information fed back by the terminal device for indicating the processing capacity of the target service requested to be transmitted within the first time delay, the scheme can ensure the transmission rate of the target service.
