Description

Technical Field

The present application relates to the field of, but is not limited to, computers, and in particular, to a data transmission method, a network device, a terminal device, a core network device, and a computer readable storage medium.

Background

As service types and communication requirements tend to be diversified, data flows of services are also changed in real time according to user requirements; personalized applications such as ultra-high definition time-frequency (XR) services place higher demands on network communications.

However, for the transmission mechanism of the current network based on service quality (Quality of Service, qoS), the granularity of the service level distinction at the core network side is relatively coarse, the period of optimization adjustment is relatively long, and the air interface resources cannot be accurately adapted to the service requirements. The radio access network (Radio Access Network, RAN) side is separated from the core network service processing side, when the RAN side adopts semi-static periodic scheduling configuration (such as discontinuous reception (Discontinuous Reception, DRX), uplink and downlink semi-static scheduling, etc.), the configuration of air interface resources cannot flexibly adapt to real-time changes of dynamic network services, so that dynamic arrival of services or dynamic changes of packet sizes cannot be well matched with scheduling resources of the RAN side in real time.

It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be arbitrarily combined with each other.

Fig. 1 is a schematic diagram of an application scenario according to an embodiment of the present application.

As shown in fig. 1, a wireless communication system 100 may include a terminal device 110 and a network device 120. Network device 120 may communicate with terminal device 110 over the air interface. Multi-service transmission is supported between terminal device 110 and network device 120.

It should be understood that embodiments of the present application are illustrated by way of example only in wireless communication system 100, and embodiments of the present application are not limited thereto. That is, the technical solution of the embodiment of the present application may be applied to various communication systems, for example: long term evolution (Long Term Evolution, LTE) systems, LTE time division duplex (Time Division Duplex, TDD), universal mobile telecommunications system (Universal Mobile Telecommunication System, UMTS), internet of things (Internet of Things, ioT) systems, narrowband internet of things (Narrow Band Internet of Things, NB-IoT) systems, enhanced machine type communications (ENHANCED MACHINE-Type Communications, eMTC) systems, 5G communication systems (also known as New Radio (NR) communication systems), or future communication systems, etc.

In the wireless communication system 100 shown in fig. 1, the network device 120 may be an access network device that communicates with the terminal device 110. The access network device may provide communication coverage for a particular geographic area and may communicate with terminal devices 110 (e.g., UEs) located within the coverage area.

Wireless terminal device 110 includes, but is not limited to, any terminal device that employs a wired or wireless connection with network device 120 or other terminal devices.

For example, the terminal device 110 may refer to an access terminal, user Equipment (UE), subscriber unit, subscriber station, mobile station, remote terminal, mobile device, user terminal, wireless communication device, user agent, or User Equipment. An access terminal may be a cellular telephone, a cordless telephone, a session initiation protocol (Session Initiation Protocol, SIP) phone, an IoT device, a satellite handset, a wireless local loop (Wireless Local Loop, WLL) station, a Personal digital assistant (Personal DIGITAL ASSISTANT, PDA), a handset with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a 5G network or a terminal device in a future evolution network, etc.

The terminal Device 110 may be used for Device-to-Device (D2D) communication.

The wireless communication system 100 may further comprise a core network device 130 in communication with the base station, which core network device 130 may be a 5G core,5gc device, e.g. an access and mobility management function (ACCESS AND Mobility Management Function, AMF) device, further e.g. an authentication server function (Authentication Server Function, AUSF) device, further e.g. a user plane function (User Plane Function, UPF) device, further e.g. a session management function (Session Management Function, SMF) device. Optionally, the Core network device 130 may also be a packet Core evolution (Evolved Packet Core, EPC) device of the LTE network, for example, a session management function+a data gateway (Session Management Function +core PACKET GATEWAY, SMF +pgw-C) device of the Core network. It should be appreciated that SMF+PGW-C may perform the functions performed by both SMF and PGW-C. In the network evolution process, the names of the core network devices may be changed, or new network entities may be formed by dividing the functions of the core network, which is not limited in the embodiment of the present application.

Communication may also be achieved by establishing a connection between the various functional units in the wireless communication system 100 via a next generation Network (NG) interface.

For example, the terminal device establishes an air interface connection with the access network device through an NR interface, and is used for transmitting user plane data and control plane signaling; the terminal equipment can establish control plane signaling connection with AMF through NG interface 1 (N1 for short); an access network device, such as a next generation radio access base station (gNB), can establish a user plane data connection with a UPF through an NG interface 3 (N3 for short); the access network equipment can establish control plane signaling connection with AMF through NG interface 2 (N2 for short); the UPF can establish control plane signaling connection with the SMF through an NG interface 4 (N4 for short); the UPF can interact user plane data with the data network through an NG interface 6 (N6 for short); the AMF may establish a control plane signaling connection with the SMF through NG interface 11 (N11 for short); the SMF may establish a control plane signaling connection with the PCF via NG interface 7 (N7 for short).

The steps of traffic data transmission between the terminal device 110, the network device 120 and the core network device 130 include: upon arrival of the downstream data packets, the core network device 130 maps the traffic data packet flows to QoS flows to ensure quality of service (e.g., bandwidth, latency, and packet loss rate). Each service data packet may be marked with a QoS Flow Identifier (QFI), and when the core network device 130 forwards the service data packet, the UPF performs the same forwarding process on the service data packet with the same QFI, such as the same scheduling priority, the same admission threshold, and the like, and sends the service data packet to the network device 120 through the N3 interface corresponding to the QoS Flow. The network device 120 determines an air radio bearer and QoS parameters corresponding to the QoS flow of the service data packet based on the QFI, and then transmits the service data packet to the terminal device 110. Wherein the network device 120 controls the mapping of QoS flows to air-interface radio bearers.

When the terminal device 110 sends data to the network device 120, the application layer of the terminal device 110 maps the data to a certain QoS flow through QoS mapping rules; and then sending uplink data to the network device 120 according to the air interface transmission parameter configuration at the network device 120 side, wherein the network device 120 encapsulates the User data into a universal packet radio system tunnel protocol User Plane (GTP-U) message, and sends the message to a UPF of the core network device through an N3 interface, and the UPF acquires data sent by the terminal from the message and sends the data to the data network through an N6 interface.

Fig. 2 is a flow chart of a data transmission method according to an embodiment of the present application, as shown in fig. 2, where the method is applied to the wireless communication system 100 shown in fig. 1, and the method includes:

Step 201, the terminal device and/or the core network device send a first message to the network device when the terminal device and/or the core network device obtain the first service data.

The first message carries a first air interface transmission parameter; the first air interface transmission parameter is an air interface transmission parameter which is expected to be used when the network equipment and the terminal equipment carry out first service data transmission.

In the embodiment of the present application, the first message may be a message encapsulated with a first air interface transmission parameter and first service data; or may be an indication message containing only the first air interface transmission parameter.

In the embodiment of the present application, the first air interface Transmission parameter includes a plurality of Transmission indexes used by the terminal device and/or the core network device to transmit service data, where the first air interface Transmission parameter includes, but is not limited to, the number of subcarriers included in one Resource Block (RB), RB location, DRX cycle, semi-PERSISTENT SCHEDULING (SPS) cycle, scheduling request cycle, uplink scheduling grant cycle, subcarrier interval, length of Cyclic Prefix (CP), and Transmission time interval (Transmission TIME INTERVAL, TTI) length.

In the embodiment of the present application, the obtaining in step 201 may be understood as determining make, generating generate, obtaining get/receive, determining determine. Illustratively, the core network device obtaining the first service data may be understood as that the downlink service data packet arrives at the core network device. The obtaining of the first service data by the terminal device may be understood as the terminal device generating the service data.

In the embodiment of the application, the first message may be various; the first message may be a request message, an indication message, a response message, etc., or may be a radio resource control (Radio Resource Control, RRC) reconfiguration message, a short message, etc.

In the embodiment of the application, the core network equipment can send a first message to the network equipment through an N3 interface; the terminal equipment can send a first message to the network equipment through the air interface resource under the historical air interface transmission parameter configuration. It should be noted that, the terminal device may send the first message to the network device based on the existing communication channel, so that the terminal device is better compatible with the existing system and reduces the cost of system modification.

In some embodiments, for the first message carrying the first air interface transmission parameter, the first message may directly carry the first air interface transmission parameter, or may carry an identifier or index of the first air interface transmission parameter; because each air interface transmission parameter in the related art communication protocol corresponds to one identifier, the network device receives the identifier of the first air interface transmission parameter included in the first message, analyzes the identifier, and determines the first air interface transmission parameter expected to be used for transmitting service data.

In the embodiment of the application, the first air interface transmission parameter is an air interface transmission parameter which is determined by the terminal equipment and/or the core network equipment and is matched with the first service data to be transmitted; when the service requirement of the terminal device and/or the core network device changes, that is, when the service data to be transmitted changes, the terminal device and/or the core network device can send a first message carrying a first air interface transmission parameter to the network device, so that the air interface transmission parameter of an air interface resource between the network device and the terminal device changes in time, and the change of the service requirement can be adapted.

Step 202, the network device receives a first message sent by the terminal device and/or the core network device.

Step 203, the network device determines a second air interface transmission parameter used when the network device performs the first service data transmission with the terminal device based on the first air interface transmission parameter.

In the embodiment of the application, the network equipment can determine whether the first air interface transmission parameter needs to be adjusted based on the actual requirement of the service, and if the first air interface transmission parameter does not need to be adjusted, the second air interface transmission parameter is the first air interface transmission parameter; and if the first air interface transmission parameter needs to be adjusted, adjusting the first air interface transmission parameter to obtain a second air interface transmission parameter. That is, under the condition that the first air interface transmission parameter needs to be adjusted, the network device determines a more appropriate air interface transmission parameter based on the first air interface transmission parameter, so that the service requirement can be accurately adapted and the air interface resource can be efficiently utilized.

It should be noted that the second air interface transmission parameter of the present application is associated with the first air interface transmission parameter.

Step 204, the network device sends a second message to the terminal device.

The second message is used for indicating the configuration of the second air interface transmission parameter. The indication here may be that the second message includes a specific indication field, or that the second message itself indicates the second air interface transmission parameter configuration.

In the embodiment of the present application, indicating the second air interface transmission parameter configuration refers to changing the parameter configuration of the air interface resource between the network device and the terminal device into the second air interface transmission parameter, and then the network device and the terminal device communicate on the air interface resource of the second air interface transmission parameter.

In the embodiment of the present application, the second air interface transmission parameter includes a plurality of transmission indexes used by the terminal device and the core network device to actually transmit the service data, and the second air interface transmission parameter includes, but is not limited to, the number of subcarriers included in one RB, RB position, DRX cycle, SPS cycle, scheduling request cycle, uplink scheduling grant cycle, subcarrier interval, length of CP, and TTI length.

In the embodiment of the present application, the second message includes, but is not limited to, a feedback message, an indication message, response information, a reply message, an acknowledgement message, and the like.

In the embodiment of the present application, the second message further includes time information, where the time information is used to indicate a time of changing the configuration of the air interface parameter, and the second air interface parameter is used at a next time or a subframe.

In the embodiment of the application, when the number of the terminal devices is multiple, the media surface communication channel established by the network device is a one-to-many multicast/broadcast/multicast communication channel, so that the second message is only sent once through the established multicast/broadcast/multicast communication channel, and other terminals can receive the second message, thereby effectively reducing the sending quantity of the second message. Of course, the network device may send the second message to the terminal device in unicast.

Step 205, the terminal device receives the second message sent by the network device.

And 206, the network equipment performs service data transmission with the terminal equipment through the air interface resource under the configuration of the second air interface transmission parameter.

In the implementation of the present application, the air interface resources are generally represented by parameters such as Resource Element (RE), RB, symbol (symbol), subcarrier (subcarrier), TTI, etc. The air interface resource can be divided from a frequency domain and a time domain, the minimum resource granularity of the frequency domain division is a subcarrier, and the minimum resource granularity of the time domain division is symbol. One RE represents a resource corresponding to one subcarrier in one symbol, and each RE may carry certain information. The M subcarriers within one TTI together constitute one RB.

It should be noted that, for the execution body of the service data transmission in step 206 may also be a terminal device, and then step 205 may be followed by the following steps: and the terminal equipment performs service data transmission with the network equipment through the air interface resource under the configuration of the second air interface transmission parameter.

The embodiment of the application provides a data transmission method, wherein under the condition that terminal equipment and/or core network equipment obtain first service data, the terminal equipment and/or the core network equipment send a first message to network equipment; the network equipment receives a first message sent by the terminal equipment and/or the core network equipment; the network equipment determines a second air interface transmission parameter used when the network equipment performs first service data transmission with the terminal equipment based on the first air interface transmission parameter; the network equipment sends a second message to the terminal equipment; the terminal equipment receives a second message sent by the network equipment; and the network equipment performs service data transmission with the terminal equipment through the air interface resource under the configuration of the second air interface transmission parameter. That is, the core network device and/or the terminal device send a first message carrying a first air interface transmission parameter to the network device, so that the network device flexibly adjusts air interface resources used by the network device and the terminal device based on the first air interface transmission parameter, so as to cope with data transmission performance requirements of uplink and downlink services in different application scenarios. Meanwhile, the terminal equipment and/or the core network equipment actively trigger the configuration of the air interface transmission parameters, so that the configuration of the air interface transmission parameters can be dynamically adapted to the service requirements in real time, support the service transmission performance of different QoS requirements borne by the network, and ensure that the scheduling resources of the base station can be well matched with the dynamic arrival of the service or the dynamic change of the packet size.

In some embodiments, the first air interface transmission parameter is obtained by the terminal device and/or the core network device based on at least one of a data amount of the first service data and a quality of service QoS parameter of the first service data in case the terminal device and/or the core network device obtains the first service data.

Here, the QoS parameters of the first traffic data include, but are not limited to, resource type, priority, packet delay prediction, packet loss rate, maximum data burst size, averaging window, allocation and reservation priority, reverse push QoS attribute, and notification control.

In some embodiments, the first message in step 201 carries the service identifier of the first service data, and then in step 206, the network device performs service data transmission with the terminal device through the air interface resource under the configuration of the second air interface transmission parameter, including:

and the network equipment transmits service data associated with the service identifier with the terminal equipment through the air interface resource.

In the embodiment of the application, when the core network device and/or the terminal device send the first message to the network device, the first message carries the expected air interface transmission parameter and the service identifier of the service data to be transmitted. That is, after the core network device and/or the terminal device obtain the first service data, the core network device sends an air interface transmission parameter expected to be used for transmitting the service data with the first service identifier to the network device; here, the first service identifier is a service identifier of the first service data.

It should be noted that, the core network device and/or the terminal device may send the first message after determining/generating/obtaining/determining the first service data for the first time; here, the first message is used for configuring the air interface transmission parameter of the service data with the first service identifier for the first time; of course, the core network device and/or the terminal device may re-determine/generate/obtain/determine the first service data, that is, send the first message after the service requirement of the first service data changes, and then the first message is used to update or adjust the air interface transmission parameter of the service data with the first service identifier.

Further, in the case that the core network device and/or the terminal device send, to the network device, an air interface transmission parameter, i.e. a first air interface transmission parameter, which is expected to be used for transmitting a certain type of service data corresponding to the first service identifier, the network device may determine an air interface transmission parameter, i.e. a second air interface transmission parameter, actually used for transmitting the certain type of service data, and configure the second air interface transmission parameter, where the network device and the terminal device directly use the second air interface parameter to transmit the service data with the first service identifier.

In some embodiments, if the network device determines, in step 203, based on the first air interface transmission parameter, a second air interface transmission parameter used when performing the first service data transmission with the terminal device, which is different from the first air interface transmission parameter, that is, the network device adjusts the first air interface transmission parameter, and sends a fourth message to the terminal device and/or the core network device; and the terminal equipment and/or the core network equipment receives the fourth message sent by the network equipment.

The fourth message is used for updating the first mapping relation by adopting the second air interface transmission parameter; the first mapping relation is a mapping relation between the service identifier and an air interface transmission parameter adopted for transmitting the data with the service identifier.

In the embodiment of the present application, before the core network device and/or the terminal device send the first air interface transmission parameter expected to be used for transmitting the service data with the first service identifier to the network device, the core network device and/or the terminal device may establish a mapping relationship between the first service identifier and the service data with the first service identifier, if the network device determines, based on the first air interface transmission parameter, the second air interface transmission parameter used when the network device performs the first service data transmission with the terminal device in step 203, and is different from the first air interface transmission parameter, the network device sends a message for adjusting the mapping relationship to the core network device and/or the terminal device, so that the air interface transmission parameter stored in the core network device and/or the terminal device is most matched with the service identifier.

In the embodiment of the present application, the fourth message includes, but is not limited to, a feedback message, an indication message, response information, a reply message, an acknowledgement message, and the like.

Fig. 3 is a schematic flow chart of data transmission provided by the present application.

Step 301, the service data packet arrives at the core network device.

Step 302, the core network device sends auxiliary information carrying downlink air interface transmission configuration parameters expected to be configured by the base station by the core network device to the base station.

In the embodiment of the application, the core network equipment encapsulates the auxiliary information in the service data packet and forwards the auxiliary information to the base station. The auxiliary information carries downlink air interface transmission configuration parameters configured by the core network device, for example, the RAN device, and further indicates a mapping relationship between the downlink air interface transmission configuration parameters and downlink service indexes.
