Description

Technical Field

[0001] The present application belongs to the field of wireless communication technology, and specifically relates to a method, device and terminal for triggering an uplink data transmission enhancement process. Background Art

[0002] For uplink data transmission, the protocol layer on the User Equipment (UE) side includes the application layer protocol and the wireless transmission protocol. The transmission protocol of the application layer varies according to different applications. Typical protocols include the Transmission Control Protocol (TCP) / Internet Protocol (IP), data encryption protocol, and data compression protocol. After the application layer performs data compression, encryption, and packaging according to these protocols, it transmits the data to the wireless protocol layer. The Service Data Adaptation Protocol (SDAP) layer in the wireless protocol layer maps the data to the wireless bearer, that is, the corresponding Packet Data Convergence Protocol (PDCP) / Radio Link Control (RLC) bearer. If there is no uplink transmission permission available at present, the Medium Access Control (MAC) layer triggers the Scheduling Request (SR) and / or Buffer Status Report (BSR) procedures to request uplink time and frequency resources from the base station and start uplink data transmission.

[0003] In the related art, for uplink data transmission, based on the current protocol layering, the data processing at the application layer and the wireless protocol layer is serial, that is, after the application layer processes the original data (such as encryption, compression, and packaging, etc.), it transmits the processed data to the wireless protocol layer, and then the wireless protocol layer starts the uplink data transmission process, such as the data transmission process based on the SR / BSR program. The total uplink transmission delay is the sum of the processing delay of the application layer and the processing transmission delay of the wireless protocol layer. For services with large data volumes and delay sensitivity, the processing time of the application layer is relatively long, resulting in a large delay in uplink data transmission.

[0025] The triggering scheme of the uplink data transmission enhancement process provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0026] Figure 2 A flowchart of a method for triggering an uplink data transmission enhancement process in an embodiment of the present application is shown. The method 200 can be executed by the application layer of the terminal. In other words, the method can be executed by software installed on the terminal. Figure 2 As shown, the method may include the following steps.

[0027] S210, the application layer of the terminal generates original service data.

[0028] In a specific application, the application layer of the terminal can generate service raw data when executing a certain service. For example, a user uses an application installed on the terminal, such as an instant messaging program, to generate voice data.

[0029] S212, based on the pre-configured data processing flow and transmission parameters, evaluate the data transmission coordination control information corresponding to the original data of the service, wherein the data transmission coordination control information includes: the amount of data after the original data of the service is processed, and / or the time information when the processed original data of the service arrives at the wireless protocol layer.

[0030] In the embodiment of the present application, the pre-configured data processing flow corresponding to different applications may be different, that is, different applications may apply different data processing configurations, and optionally, the data processing flow may include but is not limited to encryption, compression, and packaging, etc. The application layer can evaluate the processing time of the original business data and the amount of data after processing based on the pre-configured data processing flow.

[0031] In an embodiment of the present application, the transmission parameters may include pre-configured frame timing and transmission rate of data transmitted to the wireless protocol layer. The application layer can evaluate the transmission time of the processed data from the application layer to the wireless protocol layer based on the transmission parameters. Based on the evaluated processing time and transmission time of the original service data, the application layer can evaluate the time information when the processed original service data arrives at the wireless protocol layer.

[0032] In the embodiments of the present invention, the application layer mentioned may be a certain protocol layer or functional module of an application installed on a wireless terminal, or may refer to an adaptation layer or functional module in an operating system on a wireless terminal for data transmission between an upper layer application and a wireless modem module. In the description of the embodiments of the present application, for convenience, the term application layer is used for description.

[0033] Since the clock of the wireless protocol layer may be inconsistent with the clock of the wireless protocol layer, in order to avoid ambiguity, in a possible implementation, the time information can be used to indicate the relative time of the arrival time of the processed original data of the service relative to the current time. That is, the time information can indicate how long it takes for the data to arrive at the wireless protocol layer.

[0034] Alternatively, in another possible implementation, the time information may indicate the time under the time system of the wireless protocol layer or indicate the time under the time system of the wireless communication system. For example, a mapping relationship between the application layer time and the wireless protocol layer time may be established at the application layer, and the time when the processed original service data arrives at the wireless protocol layer may be converted from the application layer time to the wireless protocol layer time, so that the obtained time information is the time under the time system of the wireless protocol layer. Alternatively, the application layer may also convert the time into the time under the time system of the wireless communication system, for example, the time information sent is the clock identifier under the 5G system.

[0035] Alternatively, the time information may be the time under the time system of the application layer. After receiving the time information, the wireless protocol layer converts the time indicated by the time information into the time under the time system of the wireless protocol layer or the time system of the wireless communication system.

[0036] In the above possible implementations, the time in the time system of the wireless protocol layer may be identified by one of the following:

[0037] (1) System frame number (SFN);

[0038] (2) The time slot identifier (e.g., slot index) of the primary cell (PCell) of the terminal;

[0039] (3) The time slot identifier (e.g., slot index) of the primary and secondary cells (PSCells) of the terminal;

[0040] (4) Orthogonal frequency division multiplex (OFDM) symbol identifier (e.g., symbol index).

[0041] In a possible implementation, there may be some delay jitter after the application layer data processing is completed. In order to make the estimated arrival time after processing more accurate, in this possible implementation, the time indicated by the time information is the time estimated according to the transmission parameters and then delayed by a predetermined delay jitter. That is, in this possible implementation, when the application layer notifies the wireless protocol layer of the estimated time when the data arrives at the wireless protocol layer, the delay jitter is taken into account, and the notified estimated arrival time is the estimated time delayed by an average or maximum jitter time.

[0042] In a possible implementation, the data transmission coordination control information may further include: a quality of service (QoS) flow identifier. Through this possible implementation, the wireless protocol layer may be able to learn the QoS flow corresponding to the data transmission coordination control information, so that an uplink data transmission process may be initiated in advance for the QoS flow.

[0043] In a possible implementation, if the service original data corresponds to multiple QoS flows, the data transmission coordination control information corresponding to each QoS flow is evaluated respectively. For example, for real-time video services, H264 encoding can be used, resulting in a video data being encoded into three frames: I frame, P frame and B frame, each frame can correspond to a QoS flow, and the application layer can notify the wireless protocol layer of the data transmission coordination control information corresponding to each frame.

[0044] In a possible implementation, if the service corresponding to the service original data is a periodic service, the application layer may also notify the wireless protocol layer about the period of data occurrence. Through this possible implementation, the wireless protocol layer may obtain the period of the periodic service, so that the uplink data transmission process may be triggered according to the time advance amount according to the period of the service, so as to reduce the delay of the uplink transmission of the periodic service.

[0045] S214: Send the data transmission coordination control information to the wireless protocol layer to trigger the wireless protocol layer to initiate an uplink transmission process for the original service data after transmission processing.

[0046] In an embodiment of the present application, the application layer coordinates the data transmission control information so that the wireless protocol layer can be informed of the time and / or data volume of the upcoming uplink data transmission, so that the wireless protocol layer can initiate an uplink transmission process to the network side device in advance before the uplink data sent by the application layer arrives. For example, a scheduling request (Scheduling Request, SR) is sent to the network side device, and after obtaining an initial uplink transmission license from the network side device, the initial uplink transmission license is used to send a buffer data report (Buffer Status Report, BSR) to the network side device, so that after the uplink data sent by the application layer arrives, uplink wireless data transmission can be coordinated with the network side to save the delay of uplink data transmission.

[0047] In a possible implementation, a data control module may be added to the application layer, and the data control module is used to send and receive data to the lower layer. In this possible implementation, in S214, the data transmission coordination control information may be sent to the wireless protocol layer through the data control module of the application layer.

[0048] In one possible implementation, the application layer needs to obtain information about whether the wireless protocol layer has the ability to initiate uplink data transmission in advance according to the data transmission protocol control information, so as to determine whether the wireless protocol layer supports the interaction of data transmission coordination control information with the upper layer application (referred to as the uplink data transmission enhancement process in the embodiment of the present application). On the other hand, the wireless protocol layer also needs to obtain whether the application layer supports the data transmission protocol control information corresponding to the evaluation service original data, and transmits the data transmission protocol control information to the wireless protocol layer (in the embodiment of the present application, this process is referred to as the uplink data transmission enhancement process). Therefore, in one possible implementation, the method may also include one of the following:

[0049] (1) The application layer sends registration information to the core network of the wireless communication system, wherein the registration information includes capability information, and the capability information indicates that the application corresponding to the application layer supports the uplink data transmission enhancement process; for example, the upper layer application can be registered in the core network of the wireless network, and the registration information includes whether the application supports the use of the uplink data transmission enhancement process (that is, it supports evaluating the data transmission protocol control information corresponding to the service original data before the service original data is processed, and transmitting the data transmission protocol control information to the wireless protocol layer). The core network can notify the UE (that is, the wireless protocol layer of the UE) whether the application supports the above-mentioned uplink data transmission enhancement process.

[0050] (2) The application layer reads the wireless device configuration information of the terminal, and determines, based on the configuration information, that the terminal supports the enhanced uplink data transmission process, that is, after receiving the data transmission protocol control information, before the uplink data of the application layer arrives, the application layer initiates the uplink data transmission process to the network side device in advance according to the data transmission protocol control information; for example, the upper layer application supporting the enhanced uplink data transmission process can read the wireless device configuration information of the UE, such as the software version or chip model information of the wireless modem, and determine, based on the read wireless device configuration information, whether the UE supports the above-mentioned enhanced uplink data transmission process.

[0051] (3) The application layer receives a function indication sent by a core network of a wireless communication system, wherein the function indication indicates that the terminal supports the uplink data transmission enhancement process. For example, the UE reports the function of supporting the uplink data transmission enhancement process to the core network of the wireless network for storage, and the core network notifies the application installed by the UE that the UE supports the uplink data transmission enhancement process. For example, the core network sends the uplink data enhancement configuration to the application during the UE installation, update and / or UE application registration process.

[0052] In a possible implementation, the application layer may send a start request to the wireless protocol layer to request the wireless protocol layer to start the uplink data transmission enhancement process when determining that the UE (i.e., the wireless protocol layer of the UE) supports the above-mentioned uplink data transmission enhancement process, or when determining whether the UE supports the above-mentioned uplink data transmission enhancement process. For example, the start request is sent to the wireless protocol layer through the above-mentioned data control module.

[0053] In the above possible implementation, after receiving the above uplink data transmission enhancement process request, the corresponding submodule of the wireless protocol layer can determine whether to agree to start the uplink data transmission enhancement process and send a response message based on the configuration of RRC. If the wireless protocol layer sends information agreeing to start the uplink data transmission enhancement process, the uplink data transmission enhancement process is successfully started. After generating the original data of the service, the application layer can execute step S212 to avoid the problem that the application layer executes an invalid uplink data transmission enhancement process because the wireless protocol layer does not support the uplink data transmission enhancement process.

[0054] In an embodiment of the present application, the application layer may start processing the service original data before, after, or simultaneously with evaluating the data transmission coordination control information corresponding to the service original data. After the processing is completed, the processed service data is sent to the wireless protocol layer. After receiving the processed service data, the wireless protocol layer may complete the SR and / or BSR process with the network side device and then perform uplink wireless data transmission with the network side device.

[0055] Figure 3 Another flowchart of a method for triggering an enhanced uplink data transmission process provided by an embodiment of the present application is shown. The method 300 can be executed by a wireless protocol layer of a terminal. In other words, the method can be executed by software and / or hardware installed on the terminal. Figure 3 As shown, the method may include the following steps.

[0056] S310, the wireless protocol layer of the terminal receives data transmission coordination control information sent by the application layer, wherein the data transmission coordination control information includes: the amount of data after processing the original service data, and / or the time information when the processed original service data arrives at the wireless protocol layer.

[0057] In a specific application, the application layer may send the data transmission coordination control information according to the method described in the above method 200. The data transmission coordination control information is the same as the data transmission coordination control information in method 200 and will not be repeated here.

[0058] In specific applications, the PDCP layer in the wireless protocol layer can add a data control module to process the data transmission coordination control information from the application layer, and the SDAP layer can extend a sub-adaptation module to transmit the data transmission coordination control information from the application layer to the corresponding PDCP entity.

[0059] In one possible implementation, if the received time information is the time under the time system of the application layer, then after receiving the data transmission coordination control information, the method may also include: converting the time information into the time under the time system of the wireless protocol layer, or converting the time information into the time under the time system of the wireless communication system. That is, in this possible implementation, in order to enable the wireless protocol layer to know the time indicated by the time information, the wireless protocol layer can convert the time information into the time under the time system of the wireless protocol layer based on the mapping relationship between the application layer time and the wireless protocol layer time. Alternatively, the wireless protocol layer can also convert the time information into the time under the time system of the wireless communication system, for example, into the clock identifier of the 5G system.

[0060] For example, the application layer can send the above-mentioned data transmission coordination control information to the wireless protocol layer. The self-adaptation module of the SDAP layer in the wireless protocol layer can convert the time of the application layer into the time of the wireless protocol layer, or the time under the time system of the wireless communication system, and send the converted time information to the corresponding PDCP layer.

[0061] S312: The wireless protocol layer starts an uplink transmission process for the original service data after transmission processing according to the data transmission coordination control information.

[0062] In a specific application, the wireless protocol layer may start an uplink transmission process for the service original data after transmission processing, which may include:

[0063] Step 1: Sending an SR to a network side device according to the data transmission coordination control information before the processed original service data arrives.

[0064] Step 2: After receiving the initial uplink transmission permission sent by the network side device, use the initial uplink transmission permission to send a BSR to the network side device, wherein the BSR is used to notify the network side device that the amount of data to be transmitted is the amount of data after processing the original data of the service.

[0065] In a possible implementation, after the wireless protocol layer of the terminal receives the data transmission coordination control information sent by the application layer, the method may also include: receiving the processed original service data sent by the application layer; after sending the BSR to the network side device, transmitting the processed original service data to the network side device. In this possible implementation, the wireless protocol layer may receive the processed original service data before or after receiving the initial uplink transmission permission sent by the network side device, or may receive the processed original service data after sending the BSR, which is not limited in the specific embodiments of the present application. Through this possible implementation, the uplink data transmission process can be initiated before the processed original service data is received, and the resources for transmitting uplink data can be requested from the network side device in advance, thereby reducing the delay.

[0066] In one possible implementation, if the data transmission protocol control information includes a QoS flow identifier, and if the wireless protocol layer receives data transmission protocol control information containing multiple different QoS flow identifiers, the wireless protocol layer can start an uplink data transmission process for the data transmission protocol control information corresponding to each QoS flow identifier.

[0067] In a possible implementation, if the application layer notifies the radio protocol layer of the service cycle, the radio protocol layer may start an uplink data transmission process in advance before each cycle arrives.

[0068] In a possible implementation, before S310, the wireless protocol layer may also obtain whether the application layer supports the enhanced uplink data transmission process (i.e., whether it supports sending data transmission coordination control information to the wireless protocol layer before the original data processing of the service is completed), or notify the application layer whether the wireless protocol layer supports the enhanced uplink data transmission process (i.e., whether it supports initiating an uplink data transmission process to the network side device after receiving the data transmission coordination control information). Therefore, before S310, the method may also include one of the following:

[0069] (1) receiving capability information sent by a network side device, wherein the capability information indicates that the application corresponding to the application layer supports the uplink data transmission enhancement process. For example, the upper layer application can be registered in the core network of the wireless network, and the registration information includes whether the application supports the use of the uplink data transmission enhancement process, and the core network informs the UE whether the application supports the uplink data transmission enhancement process.

[0070] (2) Sending a function report to a network side device, wherein the function report indicates that the terminal supports the uplink data transmission enhancement process. For example, the UE sends a function report of supporting the uplink data transmission enhancement process to the wireless network core network for storage, and the core network notifies the application installed by the UE that the UE supports the uplink data transmission enhancement process. For example, the core network sends the uplink data enhancement configuration to the application during the UE installation, update and / or UE application registration process.

[0071] In a possible implementation, the application layer may also send a start request to the wireless protocol layer to request the wireless protocol layer to start the uplink data transmission enhancement process. Therefore, in this possible implementation, before S310, the method may also include:

[0072] receiving a start request sent by the application layer, wherein the start request is used to request the wireless protocol layer to start an uplink data transmission enhancement process;

[0073] Start the uplink data sending enhancement process.

[0074] In the above possible implementation methods, the wireless protocol layer can start the uplink data transmission enhancement process upon request of the application layer to avoid starting the process when the application layer does not support the uplink data transmission enhancement process, resulting in inconsistent processing between the application layer and the wireless protocol layer.

[0075] In the above possible implementations, the wireless protocol layer may also return a response message of starting the uplink data transmission enhancement flow to the application layer after starting the uplink data transmission enhancement process, so that the application layer can know that the wireless protocol layer has started the uplink data transmission enhancement process. Alternatively, the wireless protocol layer may not return the response message, and the application layer assumes that the wireless protocol layer has started the uplink data transmission enhancement process. For example, the application layer may send the start request when it is known that the wireless protocol layer supports the uplink data transmission enhancement flow, and it may be agreed in advance that the wireless protocol layer starts the uplink data transmission enhancement flow when receiving the start request, and the wireless protocol layer does not need to send the response message to the application.

[0076] It should be noted that the triggering method of the uplink data sending enhancement process provided in the embodiment of the present application can be executed by a triggering device of the uplink data sending enhancement process, or a control module in the triggering device of the uplink data sending enhancement process for executing the triggering method of the uplink data sending enhancement process. In the embodiment of the present application, the triggering device of the uplink data sending enhancement process executing the triggering method of the uplink data sending enhancement process is taken as an example to illustrate the triggering device of the uplink data sending enhancement process provided in the embodiment of the present application.

[0077] Figure 4A structural diagram of a triggering device for an enhanced uplink data transmission process provided in an embodiment of the present application is shown, such as Figure 4 As shown, the triggering device 400 of the uplink data transmission enhancement process mainly includes: a generating module 401, an evaluating module 402 and a first sending module 403.

[0078] In an embodiment of the present application, a generation module 401 is used to generate service original data; an evaluation module 402 is used to evaluate data transmission coordination control information corresponding to the service original data according to a pre-configured data processing flow and transmission parameters, wherein the data transmission coordination control information includes: the amount of data after the service original data is processed, and / or the time information when the processed service original data arrives at the wireless protocol layer; a first sending module 403 is used to send the data transmission coordination control information to the wireless protocol layer to trigger the wireless protocol layer to initiate an uplink transmission process for the service original data after transmission processing.

[0079] In a possible implementation, the time information is used to indicate the relative time of the arrival time of the processed original service data relative to the current time.

[0080] In a possible implementation manner, the time information indicates the time in a time system of the radio protocol layer or indicates the time in a time system of a wireless communication system.

[0081] In a possible implementation, the time in the time system of the wireless protocol layer is identified by one of the following:

[0082] SFN;

[0083] The timeslot identifier of the primary cell;

[0084] The timeslot identifier of the auxiliary cell;

[0085] OFDM symbol identification.

[0086] In a possible implementation, the time indicated by the time information is the time estimated according to the transmission parameter and then delayed by a predetermined delay jitter.

[0087] In a possible implementation manner, the data transmission coordination control information further includes: a QoS flow identifier.
