The following is a first explanation of some of the terms involved in the embodiments of the present disclosure to facilitate understanding by those skilled in the art.

Air port: is commonly known as an air interface.

In wireless communication technology, an "air interface" defines the specification of the radio link between a terminal device and a network device, making wireless communication as reliable as wired communication.

Deterministic network: deterministic quality of service can be provided, deterministic services and non-deterministic services can be flexibly switched, and the level of deterministic quality of service can be provided by autonomous control. Wherein deterministic quality of service may include: time delay certainty.

Packet data convergence protocol layer (Packet Data Convergence Protocol, PDCP): transmitting user plane and control plane data, maintaining SN number of PDCP, routing and repetition (dual connectivity scenario), ciphering/deciphering and integrity protection, reordering, supporting out-of-order delivery, repeated dropping, ROHC (user plane).

Radio link control layer (Radio Link Control, RLC): error detection, error correction, ARQ (AM entity); segment reassembly (UM entity and AM entity); re-segmentation (AM entity); repeated packet detection (AM entity).

Media access layer (Medium Access Control Sub Layer, MAC): mapping between logical channels and transport channels, multiplexing/demultiplexing, scheduling, HARQ, logical channel priority setting.

The deterministic latency may refer to a deterministic latency, i.e. a latency from the sender to the receiver that is fixed. Deterministic latency may refer to, for example, the delay from the frame-based data input at the TX (transmit) end to the receipt and output of frame data at the RX (receive) end, which is consistent after each power-up, or after a connection is reestablished.

The deterministic is to ensure that the delay from the sending end to the receiving end of the data packet is fixed so as to ensure the time predictability of service data transmission. The time delay determination of each section of path in the end-to-end transmission path is beneficial to the guarantee of the overall certainty.

Having introduced some noun concepts to which embodiments of the present disclosure relate, the following describes technical features to which embodiments of the present disclosure relate.

The method and the device aim to solve the problem of time delay certainty of air interface data transmission from the terminal to the base station of the mobile network.

The following describes example embodiments of the present disclosure in detail with reference to the accompanying drawings.

Fig. 1 shows an exemplary system architecture schematic diagram of a data deterministic transmission method or data deterministic transmission apparatus that may be applied to embodiments of the present disclosure.

As shown in fig. 1, the system architecture includes a terminal 101, a server 102, a network 103, and a network side device 104; any one of the terminals 101 shown in fig. 1 may be used as a remote terminal or a relay terminal, and communication based on proximity services may be established between the remote terminal and the relay terminal, where the remote terminal may directly access the network or may access the network via the relay terminal.

The network 103 is a medium for providing a communication link between the terminal 101, the server 102, and the network-side device 104, and may be a wired network, a wireless network, a fiber optic cable, or the like.

Alternatively, the wireless network or wired network or fiber optic cable described above may use standard communication techniques and/or protocols. The network is typically the Internet, but may be any network including, but not limited to, a local area network (Local Area Network, LAN), metropolitan area network (Metropolitan Area Network, MAN), wide area network (Wide Area Network, WAN), mobile, wired or wireless network, private network, or any combination of virtual private networks.

The network side device may be a base station, a relay or an access point, etc. The base station may be a 5G or later version base station (e.g., 5G NRNB), or a base station in other communication systems (e.g., eNB base station), and it should be noted that the specific type of the network side device is not limited in the embodiments of the present disclosure.

Those skilled in the art will appreciate that the number of terminals, servers, networks, and network side devices in fig. 1 is merely illustrative, and that any number of terminals, networks, and servers may be provided as desired. The embodiments of the present disclosure are not limited in this regard.

Under the system architecture described above, the embodiments of the present disclosure provide a data deterministic transmission method that can be performed by any electronic device with computing processing capabilities.

Fig. 2 is a flow chart illustrating a method of deterministic transmission of data according to an exemplary embodiment. The method provided by the embodiment of the present disclosure may be performed by any electronic device having computing processing capabilities, for example, the method may be performed by the network-side device in the embodiment of fig. 1. In the following embodiments, the base station in the network side device is taken as an example for illustration, but the disclosure is not limited thereto.

Referring to fig. 2, the data deterministic transmission method provided by the embodiment of the present disclosure may include the following steps.

Step S202, receiving air interface data, wherein the air interface data is sent to a base station by a terminal through an air interface, and the air interface data comprises first time used for identifying the sending time of the air interface data sent by the terminal.

The above-mentioned air interface data may refer to data transmitted to the base station by an air interface.

In some embodiments, when the terminal transmits the air interface data to the base station, the transmission time of the air interface data may be marked in the air interface data.

As shown in fig. 3, when data enters the transmission buffer, the terminal may take the time of the data entering the buffer as the transmission time T0 of the data, identify the transmission time T0 in the data, and then transmit the data to the base station via the air interface.

Step S204, analyzing the air interface data to obtain a first time, and determining a second time when the base station receives the air interface data.

In some embodiments, the base station may record a second time when the air interface data arrives at the base station when the air interface data is received (as shown in fig. 4, the base station may record a time T1 when the air interface data arrives at the base station); the base station also analyzes the air interface data to determine a corresponding transmission time (i.e., a first time) when the terminal transmits the air interface data.

Step S206, determining the air interface deterministic time delay required by the service corresponding to the air interface data.

In some embodiments, each air interface data may correspond to a service that may correspond to a air interface deterministic delay (e.g., delay Tt in fig. 4). For example, in the industrial internet field, the delay requirement for the service corresponding to the control command is high, and then the delay corresponding to the service corresponding to the control command needs to be determined and known, and then an air interface deterministic delay can be set in advance for the service corresponding to the control command.

It will be understood that the above-mentioned air interface deterministic delay refers to the delay when data is transmitted over the air interface between the terminal and the base station. Those skilled in the art may set different air interface deterministic delays for different services according to actual needs, which is not limited by the present disclosure.

In some embodiments, the air interface deterministic delay may be carried directly in the air interface data.

In some embodiments, the air interface data may also carry an identifier mapped to the air interface deterministic latency, and a mapping relation table of the air interface deterministic latency and the identifier is stored in the base station or the terminal, through which the base station or the terminal can determine the air interface deterministic latency corresponding to the air interface data identifier.

And step S208, setting and starting a timer according to the first time, the second time and the air interface deterministic time delay, wherein the time difference between the second time and the first time plus the time length corresponding to the timer is equal to the air interface deterministic time delay.

In some embodiments, the time delay used by the base station to transmit data over the air interface from the beginning to the arrival at the base station may be determined by the time difference between the second time and the first time.

In some embodiments, if the time difference between the second time and the first time is greater than the air interface deterministic time delay, it indicates that the air interface data is overtime in the air interface transmission process, and the air interface data can be directly discarded and early-warned.

In some embodiments, if the time stamps of the second time and the first time are equal to the air interface deterministic time delay, which means that the time delay of the air interface data in the air transmission process is just equal to the air interface deterministic time delay, the base station may directly uplink the air interface data, for example, transmit the air interface data to a core network, which is not limited in the disclosure.

In some embodiments, if the time difference between the second time and the first time is less than the air interface deterministic time delay, which means that the time delay of the air interface data in the air transmission process is less than the air interface deterministic time delay, the base station may buffer the air interface data, and set and start a timer (such as the timer duration=tt- (T1-T0) in fig. 4) according to the second time and the first time and the air interface deterministic time delay, where the time duration corresponding to the time difference between the second time and the first time plus the timer may be equal to the air interface deterministic time delay.

In step S210, when the timer is over, the base station transmits the air interface data in an uplink manner.

In some embodiments, when the timer expires, the base station may forward the air interface data. As shown in fig. 4, the base station may transmit the air interface data in an uplink at the time t0+tt.

The above-mentioned fig. 3 corresponds to a data transmission procedure at the terminal side, and fig. 4 corresponds to a data receiving and delivering procedure at the base station side to an upper layer. Wherein:

t0 is the time when the terminal business layer submits the data packet to the air interface transmission module;

t1 is the time when the base station side receives the data packet and the time mark after the transmission through the air interface;

tt is the target delay of the packet, and is also the time for the data to be transmitted to the upper layer on the terminal side with respect to T0.

By the method, the time delay of the process from the sending of the air interface data from the terminal to the sending of the base station is always equal to the air interface deterministic time delay.

Fig. 5 is a flow chart illustrating a method of deterministic transmission of data according to an exemplary embodiment. The method provided by the embodiment of the present disclosure may be performed by any electronic device having computing processing capabilities, for example, the method may be performed by the network-side device in the embodiment of fig. 1. In the following embodiments, the base station in the network side device is taken as an example for illustration, but the disclosure is not limited thereto.

Referring to fig. 5, the data deterministic transmission method provided by the embodiment of the present disclosure may include the following steps.

In some embodiments, the terminal may include a first air interface user plane protocol stack, where the first air interface user plane protocol stack may include a first protocol layer, and the first time may be a time corresponding to when the air interface data arrives at the first protocol layer of the terminal.

In some embodiments, the base station may include a second air interface user plane protocol stack, where the second air interface user plane protocol stack may include a second protocol layer, where the second protocol layer and the first protocol layer may correspond to the same protocol, e.g., the first protocol layer and the second protocol layer may each be a PDCP protocol layer (or an RLC protocol layer or a MAC protocol layer, etc.).

Step S502, receiving air interface data, wherein the air interface data is sent to a base station by a terminal through an air interface, and the air interface data comprises first time used for identifying sending time of the air interface data sent by the terminal.

In some embodiments, the first time may be identified in a protocol data unit corresponding to a first protocol layer of the terminal.

It is understood that in the field of communication technology, each data unit arriving at the protocol layer may be referred to as a protocol data unit; the protocol data units processed by the protocol layer may be referred to as service data units; the protocol data of each layer is equal to the service data unit that can be the same as the upper layer.

In some embodiments, the protocol layer may perform segmentation, concatenation, etc. on one protocol data unit. It is understood that the data formats or data contents corresponding to the same protocol layer at the receiving end and the transmitting end may be the same.

In step S504, the base station parses the pdu corresponding to the second protocol layer to obtain a first time.

Step S506, determining the corresponding time when the air interface data arrives at the second protocol layer of the base station as the second time.

Step S508, determining the air interface deterministic time delay required by the service corresponding to the air interface data.

In some embodiments, the service data unit corresponding to the second protocol layer is obtained after the second protocol layer processes the protocol data unit corresponding to the second protocol layer.

Step S510, the service data unit corresponding to the second protocol layer is cached, and a timer is set and started according to the first time, the second time and the air interface deterministic time delay.

In some embodiments, the second protocol layer may buffer the service data unit corresponding to the second protocol layer, and set and start a timer according to the first time, the second time, and the air interface deterministic delay.

In step S512, when the timer is over, the base station transfers the service data unit corresponding to the second protocol layer to the upper layer of the second protocol layer.

In some embodiments, at the end of the timer, the second protocol layer may transfer the service data unit corresponding to the second protocol layer to an upper layer of the second protocol layer to continue uplink data transmission.

According to the method, the first protocol layer of the terminal is used for identifying the transmission time of the air interface data, the second protocol layer which is equal to the first protocol layer in the base station is used for identifying the receiving time of the air interface data, and finally the second protocol layer is used for carrying out deterministic control on the transmission time of the air interface data between the first protocol layer and the second protocol layer, so that the transmission time delay of the air interface data between the first protocol layer of the terminal and the second protocol layer of the base station is fixedly known, and the certainty of the air interface transmission time delay of data transmission is improved.

Fig. 6 is a flow chart illustrating a method of deterministic transmission of data according to an exemplary embodiment. The method provided by the embodiments of the present disclosure may be performed by any electronic device having computing processing capabilities, for example, the method may be performed by the terminal in the embodiment of fig. 1 described above. In the following embodiments, the terminal is taken as an example for the execution subject, but the present disclosure is not limited thereto.

Referring to fig. 6, the data deterministic transmission method provided by the embodiment of the present disclosure may include the following steps.

Step S602, determining target data to be transmitted to the base station.

In some embodiments, any data to be sent to the base station in the terminal may be target data in very small applications, and the size, type, etc. of the target data are not limited in the present disclosure.

Step S604, determining a first time corresponding to when the target data arrives at the sending module of the terminal.

The sending module may be a sending mix corresponding to the terminal device, and each data to be sent from the terminal can be sent only after being queued by the buffer.

In step S606, the first time is marked in the target data.

In some embodiments, the first time may be identified in the target data by a protocol layer in an air interface user plane stack in the terminal, and the first time may also be identified in the target data by an application program or an application protocol layer in the terminal, or the like, and the disclosure does not limit the execution subject for identifying the first time.

Step S608, the target data carrying the first time is sent to the base station through the air interface, so that the base station controls the actual air interface transmission delay of the target data based on the first time, the second time when the target data arrives at the base station, and the air interface deterministic delay required by the service corresponding to the target data.

By the method, the time delay of the process from the sending of the air interface data from the terminal to the sending of the base station is always equal to the air interface deterministic time delay.

Fig. 7 is a flow chart illustrating a method of deterministic transmission of data according to an exemplary embodiment. The method provided by the embodiments of the present disclosure may be performed by any electronic device having computing processing capabilities, for example, the method may be performed by the terminal in the embodiment of fig. 1 described above. In the following embodiments, the terminal is taken as an example for the execution subject, but the present disclosure is not limited thereto.

Referring to fig. 7, the data deterministic transmission method provided by the embodiment of the present disclosure may include the following steps.

In some embodiments, a terminal may include a first air interface user protocol stack, which may include a first protocol layer. The first protocol layer may be a PDCP protocol layer or an RLC protocol layer or a MAC protocol layer, etc., which is not limited by the present disclosure.

Step S702, determining target data to be transmitted to a base station.

In step S704, the terminal uploads the target data to the first protocol layer of the first air interface user protocol stack.

In step S706, the time when the target data arrives at the first protocol layer is determined as the first time.

In step S708, the terminal inserts the first time into a protocol data unit corresponding to the target data at the first protocol layer position, where the protocol data unit carries the target data and is used to generate air interface data sent to the base station.

Step S710, the target data carrying the first time is sent to the base station through the air interface, so that the base station controls the actual air interface transmission time delay of the target data based on the first time, the second time when the target data arrives at the base station and the air interface deterministic time delay required by the service corresponding to the target data.

In some embodiments, for 5G NR air time labeling at the terminal, time extraction at the base station, labeling and extraction protocol layers may be performed at the following locations:

1. in the PDCP layer, transmission delay certainty of the PDCP layer can be guaranteed. The closer to the higher layer, the more favorable the calculation of the time delay of the service layer, the determination of the time delay of the upper layer can be maintained, the final time delay is the time delay of the service layer, and the closer to the service layer, the better the conversion is.

2. In the RLC layer, transmission delay certainty of the RLC layer can be ensured.

3. At the MAC layer, the transmission delay certainty of the MAC layer can be ensured.

The specific operation steps are as follows:

1. the terminal side uploads data to the corresponding protocol layer, and the arrival time is recorded as T0.

2. The terminal inserts the T0 time stamp into the associated protocol layer PDU.

3. And the terminal continues the PDU corresponding to the relevant protocol layer with the time identifier T0 and then transmits the PDU through the air interface.

4. The base station receives the air interface data and records the arrival time T1 of the base station side reaching the corresponding protocol layer;

5. The base station interprets the related protocol layer PDU and acquires the time identifier T0.

6. The base station caches SDU data of the relevant protocol layer, and sets a cache timer, and the duration of the timer is set to Tt- (T1-T0).

7. When the base station buffer timer expires, the data is submitted to the upper layer.

In the embodiment, on one hand, the terminal marks time before data enter the sending queue, and records the time point when the data enter the sending buffer; on the other hand, the base station receives the data, interprets the time of sending the data, compares the time with the target time delay, caches the situation that the target time delay is not reached, and submits the time until the target time delay meets the time; packets that are greater than the target delay may be discarded or otherwise processed.
