技术领域technical field

本发明涉及无线技术领域，尤其是指一种数据传输方法、装置、网络侧设备及终端。The present invention relates to the field of wireless technology, in particular to a data transmission method, device, network side equipment and terminal.

背景技术Background technique

在5G网络中，随着大规则多输入多输出(Massive Multiple-Input Multiple-Output，Massive MIMO)的应用，基站站点能耗费用(电费)相比于4G网络更高，为优化成本结构和促进社会效益，针对基站站点的节能减排已成为运营商的一大努力目标。In the 5G network, with the application of Massive Multiple-Input Multiple-Output (Massive MIMO), the energy consumption cost (electricity charge) of the base station site is higher than that of the 4G network. In order to optimize the cost structure and promote Social benefits, energy saving and emission reduction for base station sites has become a major goal of operators.

在现网中，网络并非时时保持高话务量，但大部分基站设备却始终保持持续运行状态，能耗并没有随话务量动态调整，造成了相当大的浪费。因此对于主设备而言，如何通过基站部分硬件关断的方式降低能耗，同时保证用户的通话、上网体验，就成为了基站节能的主要考虑方向。In the existing network, the network does not maintain high traffic all the time, but most of the base station equipment keeps running continuously, and the energy consumption is not dynamically adjusted according to the traffic volume, resulting in considerable waste. Therefore, for the main equipment, how to reduce energy consumption by turning off part of the hardware of the base station, while ensuring the user's call and Internet experience, has become the main direction of energy conservation of the base station.

符号关断是目前主要采用的节能方案之一。符号关断指基站在检测到部分下行符号没有发送数据时，在该些“没有发送数据”的符号周期关闭功率放大器PA，达到节省PA静态功耗的目的。现有的符号关断主要考虑通过将下行的数据包汇聚在某些时隙发送，空出的时隙可以进行符号关断，提高节能效果。Symbol off is one of the main energy-saving schemes currently used. Symbol turn-off means that when the base station detects that some downlink symbols do not transmit data, it turns off the power amplifier PA during these "no data transmission" symbol periods, so as to save the static power consumption of the PA. The existing symbol off mainly considers that downlink data packets are aggregated and sent in certain time slots, and the vacant time slots can be used to perform symbol off to improve the energy saving effect.

然而，现有技术采用符号关断实现节能的方式，通常将数据集中发送，提高占空比，以空出更多符号可以关断，但这种方式会引入业务时延，对时延敏感业务有很大的影响。However, the existing technology adopts the method of turning off symbols to achieve energy saving. Usually, the data is sent in a centralized manner, and the duty cycle is increased to free up more symbols to be turned off. However, this method will introduce service delays and delay-sensitive services Have a great impact.

When performing service packet scheduling and transmission, Considering the service delay comprehensively, the service packet transmission scheduling and symbol shutdown are carried out to maximize the energy-saving effect of the base station on the premise of ensuring the service experience, and to avoid the problem that the symbol shutdown method affects delay-sensitive services.

In the current transmission time slot, if the waiting delay value of the target service packet reaches the time delay target value, and the symbol occupied by the system information of the current transmission time slot has resource remaining, then in the system information The target service packet is transmitted on the remaining resources occupied by symbols.

本发明实施例所述数据传输方法，需要说明的是，所述时延目标值为目标业务包的时延需求值，用于反应目标业务包时延的需求。In the data transmission method described in the embodiment of the present invention, it should be noted that the delay target value is the delay requirement value of the target service package, which is used to reflect the delay requirement of the target service package.

本发明实施例中，可选地，所述方法还包括：In the embodiment of the present invention, optionally, the method further includes:

根据用户层面的通用无线分组业务(General packet radio service，GPRS)隧道传输协议GTP包头中的时延标识字段，获得所述目标业务包的时延目标值；或者Obtaining the delay target value of the target service packet according to the delay identification field in the GTP packet header of the general packet radio service (GPRS) tunneling transmission protocol at the user level; or

根据签约切片业务的服务级别协议(Service Level Agreement，SLA)参数，获得所述目标业务包的时延目标值。According to the Service Level Agreement (Service Level Agreement, SLA) parameter of the contracted slice service, the delay target value of the target service package is obtained.

采用上述任一实施方式，网络侧设备能够识别获取目标业务包的时延目标值。By adopting any of the above implementation manners, the network side device can identify and acquire the target delay value of the target service packet.

可选地，其中一实施方式，核心网或者终端通过深度报文检测(Deep PacketInspection，DPI)识别业务类型，从而得到目标业务包的时延目标值(可选地，可根据人工经验或AI方式获取该时延目标值)，例如云游戏的时延目标值可以为20ms，工厂控制类业务的时延目标值可以为10ms等。进一步地，核心网或终端在用户层面的通用无线分组业务GPRS隧道传输协议GTP-U包头增加字段标识时延目标值，并将数据包发送至网络侧设备。这样，网络侧设备根据该GTP-U包头，可以获得时延目标值。Optionally, in one embodiment, the core network or the terminal identifies the service type through deep packet inspection (Deep PacketInspection, DPI), so as to obtain the delay target value of the target service packet (optionally, it can be based on artificial experience or AI mode Obtain the latency target value), for example, the latency target value of cloud games can be 20ms, and the latency target value of factory control services can be 10ms, etc. Further, the core network or the terminal adds a field identifying the delay target value to the GPRS Tunneling Protocol GTP-U packet header at the user level, and sends the data packet to the network side device.

With this implementation mode, when a slice is signed, the SLA parameters of the slice service are signed at the same time, including the delay target value of the service delay.

Consider adding Network Slice Selection Assistance Information (NSSAI) to the interface to send the corresponding target delay parameter to the network side device. The network-side device can determine the target delay requirement of the service according to the NSSAI of the user plane service package, that is, determine the target delay value of the corresponding target service package.

采用上述时延目标值的获取方式，相较于通常技术通过服务质量(Quality ofService，QoS)参数中5QI对应的分组时延预算(Packet Delay Budget，PDB)中获取时延目标值，能够获得更精细的时延值，以能够更准备反映业力时延的需求。The acquisition method of the above-mentioned delay target value, compared with the usual technique of obtaining the delay target value from the packet delay budget (Packet Delay Budget, PDB) corresponding to 5QI in the Quality of Service (QoS) parameter, can obtain more Refined delay value to be able to better reflect the needs of karmic delay.

采用本发明实施例所述数据传输方法，在每一传输时隙内，在传输每一待传输的目标业务包时，分别获取每一目标业务包的时延目标值，将目标业务包的当前的等待时延值与相应的时延目标值比较，并确定当前传输时隙的系统占用符号是否存在资源剩余，优先调度等待时延值达到时延目标值的目标业务包，并在当前传输时隙的系统信息占用符号的剩余资源上网络服务目标业务包，以尽可能地空出更多符号进行关断，达到提升网络侧设备节能效率的目的。By adopting the data transmission method described in the embodiment of the present invention, in each transmission time slot, when transmitting each target service package to be transmitted, the time delay target value of each target service package is respectively obtained, and the current value of the target service package is The waiting delay value is compared with the corresponding delay target value, and it is determined whether the system occupied symbol of the current transmission time slot has resource surplus, and the target service packet whose waiting delay value reaches the delay target value is prioritized, and the current transmission time slot The system information of the slot occupies the remaining resources of the symbol to serve the target business packet on the network, so as to free up as many symbols as possible for shutdown, and achieve the purpose of improving the energy saving efficiency of the network side equipment.

结合图3所示，采用本发明实施例所述数据传输方法，具体包括：As shown in FIG. 3, adopting the data transmission method described in the embodiment of the present invention specifically includes:

S310，获取待传输的目标业务包的时延目标值；S310, acquiring a target delay value of the target service packet to be transmitted;

S320，在当前传输时隙内，判断每一目标业务包的等待时延值是否达到时延目标值，以及判断当前传输时隙的系统信息占用符号是否存在资源剩余；S320. In the current transmission time slot, judge whether the waiting delay value of each target service packet reaches the delay target value, and judge whether there is resource surplus in the symbol occupied by the system information of the current transmission time slot;

可选地，判断所述目标业务包的等待时延值与所述时延目标值之间的差值是否大于预设值；其中，该预设值为预先设定的时延阈值；Optionally, judging whether the difference between the waiting delay value of the target service packet and the delay target value is greater than a preset value; wherein the preset value is a preset delay threshold;

其中，在目标业务包的等待时延值达到时延目标值，且当前传输时隙的系统信息占用符号存在资源剩余，则执行步骤S330；在目标业务包的等待时延值达到时延目标值，且当前传输时隙的系统信息占用符号不存在资源剩余，则执行步骤S340；Wherein, when the waiting delay value of the target service package reaches the delay target value, and the system information occupancy symbol of the current transmission time slot has resource surplus, then perform step S330; when the waiting delay value of the target service package reaches the delay target value , and there is no resource remaining in the system information occupied symbol of the current transmission time slot, then perform step S340;

在目标业务包的等待时延值未达到时延目标值，且当前传输时隙的系统信息占用符号存在资源剩余，则执行步骤S330；在目标业务包的等待时延值未达到时延目标值，且当前传输时隙的系统信息占用符号不存在资源剩余，则执行步骤S350；When the waiting delay value of the target service package does not reach the delay target value, and the system information occupancy symbol of the current transmission time slot has resource surplus, then perform step S330; when the waiting delay value of the target service package does not reach the delay target value , and the symbol occupied by the system information of the current transmission time slot has no remaining resources, then perform step S350;

S330，在系统信息占用符号的剩余资源上传输所述目标业务包；S330. Transmit the target service packet on the remaining resources of symbols occupied by system information;

S340，所述当前传输时隙的空域符号上传输所述目标业务包；S340. Transmit the target service packet on the airspace symbol of the current transmission time slot;

S350，在下一调度时隙传输所述目标业务包。S350. Transmit the target service packet in the next scheduled time slot.

可选地，所述系统信息占用符号包括同步信号块(Synchronization signalBlock，SSB)、信道状态指示参考信号(Channel State Indication-Reference Signal，CSI-RS)、物理下行控制信道(Physical Downlink Control Channel，PDCCH)和系统消息块SIB1中的至少之一传输符号。Optionally, the symbols occupied by the system information include a synchronization signal block (Synchronization signalBlock, SSB), a channel state indication reference signal (Channel State Indication-Reference Signal, CSI-RS), a physical downlink control channel (Physical Downlink Control Channel, PDCCH ) and at least one of the system information block SIB1 transmits symbols.

采用该实施方式，在当前传输时隙内，目标业务包的等待时延值已到达时延目标值时，则需将该目标业务包的调度优先级提至最高，优先得到调度，不再进行攒包(也即不能延迟到下一时隙发送)。同时，将该目标业务包优先在已占用符号调度(如为系统信息占用符号上发送)。可选地，系统信息占用符号是指SSB、CSI-RS、PDCCH、SIB1等会在固定位置发送所占用的符号，该些已占用符号是无法进行符号关断的，否则会影响KPI指标。若业务包在已占用符号未发送完，则可以继续在该时隙其他未占用符号进行调度，不延迟到下一个时隙发送。因此，通过在系统信息占用符号存在的剩余资源上传输业务包，可以能够在保证时延需求的条件下，能够空出更多符号进行关断，以提升信号传输的占空比，提升节能效率。With this implementation mode, in the current transmission time slot, when the waiting delay value of the target service package has reached the delay target value, the scheduling priority of the target service package needs to be raised to the highest, and the scheduling is given priority, and no further Save packets (that is, cannot be delayed until the next time slot to send). At the same time, the target service packet is prioritized for scheduling on occupied symbols (such as sending on symbols occupied for system information). Optionally, symbols occupied by system information refer to symbols occupied by SSB, CSI-RS, PDCCH, SIB1, etc., which are sent at fixed positions, and these occupied symbols cannot be turned off, otherwise KPI indicators will be affected. If the service packet has not been sent in the occupied symbol, it can continue to be scheduled in other unoccupied symbols in the time slot, and the transmission will not be delayed until the next time slot. Therefore, by transmitting service packets on the remaining resources occupied by system information symbols, more symbols can be turned off while ensuring the delay requirement, so as to increase the duty cycle of signal transmission and improve energy-saving efficiency .

在此基础上，可选地，所述方法还包括：On this basis, optionally, the method also includes:

在等待时延值达到时延目标值的每一目标业务包传输完成后，传输等待时延值未达到时延目标值的目标业务包。After the transmission of each target service packet whose waiting delay value reaches the delay target value is completed, the target service package whose waiting delay value does not reach the delay target value is transmitted.

采用该实施方式，当等待时延值到达时延目标值附近的目标业务包调度完成后，进一步对其他业务进行调度，也即在保证等待时延值达到时延目标值的每一目标业务包传输完成后，再传输等待时延值未达到时延目标值的目标业务包。当系统信息占用符号存在物理资源块(physical resource block，PRB)资源剩余时，其他业务可在剩余资源调度。若无资源剩余，则该当前传输时隙不再调度该些业务，延迟到下一传输时隙进行调度。With this implementation mode, after the scheduling of the target service package near the target delay value reaches the delay target value, other services are further scheduled, that is, each target service package whose waiting delay value reaches the delay target value is guaranteed After the transmission is completed, the target service packets whose waiting delay value does not reach the delay target value are transmitted again. When symbols occupied by system information have remaining physical resource block (physical resource block, PRB) resources, other services can be scheduled on the remaining resources. If there is no resource remaining, the current transmission time slot will no longer schedule these services, and the scheduling will be delayed until the next transmission time slot.

可选地，所述方法还包括：Optionally, the method also includes:

采用本发明实施例所述方法，网络侧设备在每个调度时隙根据业务是否到达时延目标值，差异化地进行调度与符号关断(到达时延目标值附近的用户优先在本时隙的SSB等已占用符号调度，其他用户可在已占用符号的剩余资源调度，或延迟到下一时隙调度，从而提升符号关断比例)，避免时延需求无法得到满足问题，同时能够进一步提升占空比，空出更多符号进行关断，在保证业务体验的前提下，最大程度地提升基站的节能效果。Using the method described in the embodiment of the present invention, the network side equipment performs scheduling and symbol switching in a differentiated manner in each scheduling time slot according to whether the service reaches the time delay target value (users near the time delay target value are prioritized in this time slot) SSB and other occupied symbols are scheduled, and other users can be scheduled on the remaining resources of the occupied symbols, or delayed until the next time slot, so as to increase the symbol off ratio), avoiding the problem that the delay requirement cannot be met, and can further improve the occupied The space ratio allows more symbols to be turned off, and maximizes the energy-saving effect of the base station on the premise of ensuring service experience.
