Description

Data sending method and related device

Technical Field

The present invention relates to the field of communications, and in particular, to a method and a related apparatus for transmitting data.

Background

In the existing Enhanced Machine Type Communication (eMTC), when a terminal device has uplink data to be sent, an uplink grant needs to be applied to a network. After receiving a conventional Buffer Status Report (BSR) request triggered by a Packet Data Convergence Protocol (PDCP) layer and a Radio Link Control (RLC) layer through a Media Access Control (MAC) layer, a terminal device transmits BSR information to a network device. Under the condition that the terminal device receives the Uplink authorization sent by the network device in response to the BSR information, the terminal device sends a data packet to the network device, where the data packet includes Physical Uplink Shared Channel (PUSCH) data and BSR information, and the network device receives the BSR information and then issues the Uplink authorization to the terminal device.

At present, a terminal device sends a data packet composed of PUSCH data and BSR information to a network device, and when continuous transmission of Hybrid Automatic Repeat reQuest (HARQ) data fails, the data packet is discarded due to an Unacknowledged Mode (UM) Mode adopted by a Radio Link Control (RLC). The BSR information included in the data packet is also discarded, which results in that the network device does not issue an uplink grant, and the uplink Scheduling Request (SR) is retransmitted after the retransmission BSR timer configured for the terminal device by the network device expires. This approach will have a large delay impact on delay sensitive traffic.

Referring to fig. 2, fig. 2 is a protocol architecture for transmitting data according to an embodiment of the present disclosure. The output transmission Protocol architecture between the network device and the terminal device shown in fig. 2 mainly includes a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, a Media Access Control (MAC) layer, and a physical layer. Different data processing functions exist between each layer of protocol, and the PDCP layer mainly performs security operation and header compression and decompression processing, such as encryption and integrity protection; the RLC layer mainly completes the segmented concatenation and sequential delivery of data and the data transmission guarantee of Automatic Repeat Request (ARQ); the MAC layer mainly completes scheduling, cascade processing of different logical channels, and Hybrid Automatic Repeat Request (HARQ) operation; the physical layer completes transmission block packetization and air interface transmission.

It should be noted that, when the terminal device has uplink data to send, after the terminal device receives the BSR request triggered by the PDCP layer and the RLC layer through the MAC layer, the terminal device sends BSR information to the network device. And under the condition that the terminal equipment receives uplink authorization sent by the network equipment in response to the BSR information, the terminal equipment sends a data packet to the network equipment, wherein the data packet comprises PUSCH data and the BSR information, and the network equipment receives the BSR information and then issues the uplink authorization to the terminal equipment. When the HARQ information continuous transmission fails, the packet is discarded since the RLC employs the UM mode. The BSR information contained in the data packet is also discarded, so that the network device does not issue the uplink grant, and the SR is retransmitted after the BSR retransmission timer configured for the terminal device by the network device times out. However, the current BSR retransmission timer is configured by the network device, and different services all use the same BSR retransmission timer, which cannot guarantee the delay requirements of different delay sensitive services.

Referring to fig. 3, fig. 3 is a flowchart illustrating a data transmission method according to an embodiment of the present application based on the network architecture and the device described in the foregoing.

S101, under the condition that the terminal equipment receives the uplink authorization sent by the network equipment, the terminal equipment sends a data packet to the network equipment.

The data packet includes PUSCH data and BSR information, where the BSR information is used to indicate a data amount of uplink data of a first service to be sent, which exists in the terminal device.

In this example, when the terminal device has uplink data to send, after the terminal device receives a BSR request triggered by the PDCP layer and the RLC layer through the MAC layer, the terminal device sends BSR information to the network device. And under the condition that the terminal equipment receives the uplink authorization sent by the network equipment in response to the BSR information, the terminal equipment sends a data packet to the network equipment.

S102, when the terminal equipment sends the data packet, the terminal equipment determines the time length of the BSR retransmission timer based on the requirement of the first service.

The requirement of the first service may be a requirement of a delay or a requirement of a service priority.

In a possible implementation manner, when the requirement of the first service is a requirement of a time delay, optionally, the terminal device may set a corresponding time delay requirement for each service executed; optionally, the terminal device may further set the delay requirement of a part of the services as a specific delay requirement, and set the delay requirements of other services as a default delay requirement.

For example, when the requirement of the first service is a requirement of delay, the delay requirement of the voice call service is set to be 150 milliseconds, the delay requirement of the game service is set to be 200 milliseconds, and the default delay requirement of the other services is set to be 300 milliseconds. If the first service is a voice call service, determining that the requirement of the first service is 150 milliseconds; if the first service is a game service, determining that the requirement of the first service is 200 milliseconds; if the first service is a file sending service and the service belongs to other services, a default time delay requirement of 300 milliseconds is adopted as the requirement of the first service.

In a possible implementation manner, when the requirement of the first service is a requirement of a service priority, optionally, the terminal device may set a corresponding service priority for each service to be executed; optionally, the terminal device may further set the priority of a part of the services, and set other services as a default priority.

For example, when the requirement of the first service is a requirement of a service priority, the voice call service is set to be the first priority, the game service is set to be the second priority, and other services default to be the third priority. If the first service is a voice call service, the requirement of the first service is a first priority; if the first service is a game service, the requirement of the first service is a second priority; and if the first service is a file sending service and the service belongs to other services, the requirement of the first service is a third priority.

In the present example, the terminal device executes step S101 and step S102 simultaneously. That is to say, under the condition that the terminal device receives the uplink grant sent by the network device, the terminal device sends a data packet to the network device, where the data packet includes PUSCH data and BSR information, and meanwhile, the terminal device determines the duration of the BSR retransmission timer based on the requirement of the first service.

Referring to fig. 4, fig. 4 is a flowchart of another data transmission method provided in the embodiment of the present application. Step S202 to step S206 are a specific implementation manner of step S102.

S201, under the condition that the terminal equipment receives the uplink authorization sent by the network equipment, the terminal equipment sends a data packet to the network equipment.

The execution manner of step S201 may refer to the execution manner described in step S101 in the above description, and is not described herein again.

S202, the terminal equipment determines the type of the first service.

In this example, the types of the first service include a real-time session service, a streaming media service, an interactive service, and a file reception service. The real-time session service has high requirements on transmission delay and transmission delay jitter, and the service type is usually applied to voice call service, IP (internet protocol) telephone, video telephone and the like on a circuit switching carrier; the streaming media service also has real-time performance, has higher requirements on transmission delay and transmission delay jitter, but has no strict real-time session service, and the service type is usually applied to audio and video programs and the like on a network; the interactive service has low requirement on transmission delay jitter, but has high requirement on packet loss rate, the delay requirement is usually between the delay requirements of a real-time session service and a streaming media service, and the service type is usually applied to web browsing, network games, database retrieval and the like; the file receiving service belongs to background services, the requirements on transmission delay and transmission delay jitter are not high, but the requirements on packet loss rate are high, and the service type is generally applied to mail receiving, file receiving, database downloading and the like.

It should be noted that there may be other classification manners for the service types, for example, the type of the first service may also be divided into a stream type, a session type, a background type, and an interactive type, or a session/real-time type, an interactive type, and a streaming media type, which are not described herein again. Optionally, different types of services have different delay requirements for data transmission or priorities of the services.

Alternatively, the first service may comprise only one service, in which case the type of the first service comprises only one service type. For example, the first service only includes a voice call service, and the type of the first service is a real-time session service type.

Optionally, the first service may include a plurality of services, in which case the type of the first service may include a plurality of service types, or may include only one service type. For example, the first service includes a voice call service and a game service, and the type of the first service includes a real-time conversation service type and an interactive service type. For another example, if the first service includes an audio playing service and a video playing service, and both the audio playing service and the video playing service belong to the streaming media service type, the type of the first service only includes the streaming media service type.

Optionally, the type of the first service may be subdivided into smaller service types based on the original service type. For example, real-time session traffic types may be subdivided into voice call types and video call types.

S203, the terminal device determines the time delay required by the first service based on the type of the first service.

In this example, the first service includes one service or multiple services, where one service corresponds to one type and one service type corresponds to one delay.

Optionally, the terminal device may prestore a corresponding relationship between the type of each service and the time delay. For example, the correspondence relationship may be as shown in table 1.

TABLE 1

Type of service	Time delay
		Real-time session service	150 milliseconds
Streaming media service	10 seconds
		Interactive service	200 milliseconds
File receiving service	4 seconds

Optionally, if the time delay required by the first service is in a specific range, the terminal device uses a lower limit value of the specific range as the time delay required by the first service. For example, the first service is a voice communication service, the voice communication service corresponds to a real-time session service type, and the delay requirement of the service type for voice communication is that the end-to-end delay is less than 150 milliseconds, and the terminal device determines that the delay required by the service is 150 milliseconds based on the service type.

In a possible implementation manner, the first service includes multiple services, and the determining, by the terminal device, the delay required by the first service based on the type of the first service includes: the terminal equipment determines a plurality of time delays based on the types of a plurality of services, wherein one service type corresponds to one time delay; and the terminal equipment determines the minimum time delay in the plurality of time delays as the time delay required by the first service.

For example, the first service includes a voice call service, a video play service and an interactive game service, the voice call service belongs to a real-time session service type, the video play service belongs to a streaming media service type, and the interactive game service belongs to an interactive service type. The time delay required by the voice call service is determined to be 150 milliseconds, the time delay required by the video playing service is determined to be 10 seconds, and the time delay required by the interactive game service is determined to be 200 milliseconds. By comparing the time delay of the service requirements, the minimum time delay is determined to be 150 milliseconds of the time delay required by the voice call service, and therefore, 150 milliseconds is determined to be the time delay required by the first service. Based on the possible implementation mode, under the condition that a plurality of services exist simultaneously, the time delay requirement of each service is ensured.

In another possible implementation manner, the first service includes multiple services, and the determining, by the terminal device, the delay required by the first service based on the type of the first service includes: the terminal equipment determines a plurality of time delays and a plurality of priorities based on the types of a plurality of services, wherein one service type corresponds to one time delay and one service type corresponds to one priority; the terminal equipment determines the weights of a plurality of services based on a plurality of priorities; and the terminal equipment determines the time delay required by the first service according to the weights of the services and the time delays. Alternatively, the delay required by the first service may be a sum obtained by performing weighted calculation based on the weights of the plurality of services and the plurality of delays.

For example, the first service includes a voice call service, a video play service and an interactive game service, the voice call service belongs to a real-time session service type, the video play service belongs to a streaming media service type, and the interactive game service belongs to an interactive service type. The time delay required by the voice call service is determined to be 150 milliseconds, the time delay required by the video playing service is determined to be 10 seconds, and the time delay required by the interactive game service is determined to be 200 milliseconds. Meanwhile, the priorities of the services are determined according to the service types, wherein the priority of the voice call service is the highest, the priority of the interactive game service is the next highest, and the priority of the video playing service is the lowest. Further, the weight of each service is determined by the priority of each service, and illustratively, the weight of the voice call service is 0.6, the weight of the interactive game service is 0.38, and the weight of the video play service is 0.02. The delay 366 ms is obtained by adding the product of the delay required by each service and the weight corresponding to each service, and therefore 366 ms is determined as the delay required by the first service. Based on the possible implementation mode, under the condition that a plurality of services exist simultaneously, the time delay requirement of each service is comprehensively considered.

Optionally, in a case where the first service includes two types of services, the weights corresponding to the services may be 0.7 and 0.3 (or 0.6 and 0.4, 0.8 and 0.2, and so on) in a manner that the priority is from high to low; in the case of including three types of traffic, the weights corresponding to the traffic may be 0.5, 0.3, and 0.2 (or, 0.6, 0.3, and 0.1, 0.5, 0.4, and 0.1, etc.) in a manner that the priority goes from high to low.

In yet another possible implementation manner, the first service includes a service, and the terminal device determines the delay required by the first service based on the type of the first service. Based on the possible implementation manner, the time delay requirement of the first service can be made clear, and the time length of the BSR retransmission timer can be determined subsequently.

S204, the terminal equipment determines whether the time delay required by the first service is less than the time length set by the BSR retransmission timer. If the delay required by the first service is less than the duration set by the BSR retransmission timer, step S205 is executed. If the time delay required by the first service is greater than or equal to the duration set by the BSR retransmission timer, step S206 is executed.

In this example, the duration set by the BSR retransmission timer is the duration of the BSR retransmission timer set by the network device for the terminal device. S205, the terminal device determines the time delay required by the first service as the time length of the BSR retransmission timer.

In this example, the time delay required by the first service is less than the time length set by the BSR retransmission timer, and the terminal device determines the time delay required by the first service as the time length of the BSR retransmission timer, which is beneficial to ensuring the time delay requirement of the delay sensitive service.

S206, the terminal equipment determines the time length set by the BSR retransmission timer as the time length of the BSR retransmission timer.

In this example, the time delay required by the first service is greater than or equal to the time length set by the BSR retransmission timer, and the terminal device determines the time length set by the BSR retransmission timer as the time length of the BSR retransmission timer.

For example, the duration set by the BSR retransmission timer is 180 milliseconds, the delay required by the voice communication service is 150 milliseconds, and the delay required by the interactive game service is 200 milliseconds. When the first service is a voice communication service, and the time delay 150 milliseconds required by the voice communication service is less than the time length set by the BSR retransmission timer by 180 milliseconds, the time delay 150 milliseconds required by the voice communication service is determined as the time length of the BSR retransmission timer. When the first service is an interactive game service, 200 milliseconds of time delay required by the interactive game service are greater than 180 milliseconds of time length set by the BSR retransmission timer, and the 180 milliseconds of time length set by the BSR retransmission timer is determined as the time length of the BSR retransmission timer.

In a possible implementation manner, the terminal device sends an uplink scheduling request SR to the network device under the condition that the determined BSR timer expires. And the network equipment receives the SR information and then issues an uplink authorization to the terminal equipment. Based on the possible implementation manner, the network device is ensured to issue the uplink authorization to the terminal device by receiving the SR information retransmitted by the terminal device even under the condition that the network device cannot receive the BSR information.

It can be seen that, based on the method described in fig. 4, when the terminal device receives the uplink grant sent by the network device in response to the BSR, the terminal device sends a data packet to the network device, and determines the duration of the timer for retransmitting the BSR based on the requirement of the first service, thereby ensuring the delay requirement of the delay sensitive service.

In order to implement the functions in the method provided by the embodiment of the present application, the terminal device may include a hardware structure and a software module, and implement the functions in the form of a hardware structure, a software module, or a hardware structure and a software module. Some of the above functions may be implemented by a hardware structure, a software module, or a hardware structure plus a software module.
