本发明实施例涉及通信技术领域，尤其涉及一种小数据传输信息收集方法及系统。Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method and system for collecting small data transmission information.
背景技术Background technique
现有技术中在Rel-17 5G NR系统中，引入了小数据传输SDT技术，其基本原理是处于非激活态的终端(UE)无需进入RRC连接态，即可传输少量上、下行数据。不同于传统的传输方式，即UE需先恢复RRC连接，然后才能传输数据，在传输完数据后UE释放连接回到非激活状态或空闲状态，利用SDT传输机制，UE无需进行连接状态转换，因而可减少传统终端恢复连接并在传输完毕后释放连接而产生的信令开销，另外，也可以降低终端的耗电，因此该技术特别适合于大量终端需周期性传输少量数据的物联网应用场景。In the prior art, in the Rel-17 5G NR system, the small data transmission SDT technology is introduced. The basic principle is that the terminal (UE) in the inactive state can transmit a small amount of uplink and downlink data without entering the RRC connection state. Different from the traditional transmission method, that is, the UE needs to restore the RRC connection before transmitting data. After transmitting the data, the UE releases the connection and returns to the inactive state or idle state. Using the SDT transmission mechanism, the UE does not need to perform connection state transitions, so It can reduce the signaling overhead caused by the traditional terminal resuming the connection and releasing the connection after the transmission is completed. In addition, it can also reduce the power consumption of the terminal. Therefore, this technology is especially suitable for IoT application scenarios where a large number of terminals need to periodically transmit a small amount of data.
R17小数据传输SDT技术包括两种类型，即基于随机接入的小数据传输(RA-basedSDT)，及基于配置的授权的小数据传输(CG-based SDT)。其中，RA-based SDT是指非激活态UE触发4步或2步随机接入(RA)过程，并在4步RA的消息3(Msg3)或2步RA的MsgA中携带初始上行数据，在随机接入成功完成后，UE可基于网络的动态调度进行后续的上行和/或下行数据传输。The R17 small data transmission SDT technology includes two types, namely random access-based small data transmission (RA-basedSDT), and configuration-based authorized small data transmission (CG-based SDT). Among them, RA-based SDT means that the UE in the inactive state triggers the 4-step or 2-step random access (RA) process, and carries the initial uplink data in the message 3 (Msg3) of the 4-step RA or the MsgA of the 2-step RA. After the random access is successfully completed, the UE can perform subsequent uplink and/or downlink data transmission based on the dynamic scheduling of the network.
CG-based SDT是指非激活态UE不需触发随机接入，使用原服务小区预配置的上行信道资源传输初始上行数据，后续UE可继续使用这些预配置的上行资源，或者依据网络的动态调度信息传输上行和/或下行数据。CG-based SDT means that the inactive UE does not need to trigger random access, and uses the pre-configured uplink channel resources of the original serving cell to transmit initial uplink data. Subsequent UEs can continue to use these pre-configured uplink resources, or according to the dynamic scheduling of the network Information transfers uplink and/or downlink data.
依据用户终端的类型及其业务特性，5G网络可以决定为UE提供SDT配置，但不是以UE为对象配置SDT，而是以数据无线承载(DRB)为对象，也就是说，若一个UE具有多个DRB承载，网络可以基于各承载的业务特性，选择其中一个或多个DRB配置SDT特性，从而仅当这些配置了SDT的DRB承载有上行数据要传输时，UE才可能触发SDT操作，若仅有未配置SDT特性的DRB承载有数据要传输时，则UE不触发SDT操作，而是触发非SDT传输，即RRC连接恢复过程。According to the type of user terminal and its service characteristics, the 5G network can decide to provide SDT configuration for the UE, but instead of configuring SDT for the UE, it is for the data radio bearer (DRB). That is to say, if a UE has multiple The network can select one or more DRBs to configure the SDT feature based on the service characteristics of each bearer, so that the UE may trigger the SDT operation only when these DRBs configured with SDT have uplink data to be transmitted. When a DRB with no SDT feature configured bears data to be transmitted, the UE does not trigger an SDT operation, but triggers a non-SDT transmission, that is, the RRC connection recovery process.
当UE从RRC连接态转入非激活态时，从服务小区发送的RRCRelease消息中接收SDT配置信息。对于CG-based SDT，SDT配置(包括预配置的上行资源)仅在UE接收该配置所在的小区内有效，也就是说当UE接收CG-based SDT配置后移动到另一个小区，则该CG-basedSDT配置失效并被释放。When the UE changes from the RRC connected state to the inactive state, it receives the SDT configuration information from the RRCRelease message sent by the serving cell. For CG-based SDT, the SDT configuration (including pre-configured uplink resources) is only valid in the cell where the UE receives the configuration. That is to say, when the UE moves to another cell after receiving the CG-based SDT configuration, the CG- The basedSDT configuration is invalidated and released.
通常，网络提供给UE的SDT配置信息包括以下参数：Usually, the SDT configuration information provided by the network to the UE includes the following parameters:
该SDT配置适用的DRB承载；The SDT configures the applicable DRB bearer;
决定触发SDT传输的数据量(data volume)阈值，即仅当该DRB承载上待传输的数据大小低于此阈值时才能触发SDT传输，否则触发非SDT传输方式；Determine the data volume (data volume) threshold that triggers SDT transmission, that is, SDT transmission can be triggered only when the size of the data to be transmitted on the DRB bearer is lower than this threshold, otherwise non-SDT transmission mode is triggered;
决定触发SDT传输的RSRP阈值，即仅当UE测量的当前服务小区的RSRP值高于或等于此阈值时才触发SDT传输，否则触发或非SDT传输方式；Determine the RSRP threshold to trigger SDT transmission, that is, trigger SDT transmission only when the RSRP value of the current serving cell measured by the UE is higher than or equal to this threshold, otherwise trigger or non-SDT transmission;
若配置的是RA-based类型SDT,可用的4步或2步RA preamble子集及/或可用的RACH资源位置；If RA-based type SDT is configured, available 4-step or 2-step RA preamble subsets and/or available RACH resource locations;
若配置的是CG-based类型SDT,可用的上行配置的授权资源；If the configuration is a CG-based type SDT, the available authorized resources for uplink configuration;
若配置的是CG-based SDT,上行定时提前定时器(Timing Advance Timer)；If CG-based SDT is configured, the uplink timing advance timer (Timing Advance Timer);
SDT操作定时器，若当该定时器超时UE仍未完成SDT传输，则判断SDT传输过程失败。The SDT operation timer, if the UE has not completed the SDT transmission when the timer expires, it will judge that the SDT transmission process fails.
在利用SDT技术时，非激活态终端可以无需转换到连接态即可传输数据，既能减少不必要的信令开销，减少网络负荷，又能降低终端的耗电。但是，在实际网络中，终端种类众多，不同类型的终端所传输的业务特点也大相径庭，甚至同一个终端上也可能传输多种不同特性的业务。When using SDT technology, the terminal in the inactive state can transmit data without switching to the connected state, which can not only reduce unnecessary signaling overhead, reduce network load, but also reduce terminal power consumption. However, in an actual network, there are many types of terminals, and the characteristics of services transmitted by different types of terminals are also quite different. Even the same terminal may transmit multiple services with different characteristics.
但是，实际网络中的无线信道状况也是复杂多变的。因此，网络如何选择合适的终端，进而对于一个终端如何选择合适的数据承载配置SDT，以及如何恰当地设置各个阈值，合理地分配无线传输资源而不降低网络资源使用效率，是一个亟需解决的技术问题。如果选择配置SDT的终端或数据承载不合适，或者设置的阈值参数不合适，则使用SDT传输数据，不但无法获得预期的益处，适得其反，可能会增加网络的资源消耗和信令开销，并加大终端的耗电。因此本文提出一种小数据传输信息收集方法及系统予以解决上述问题。However, wireless channel conditions in actual networks are also complex and changeable. Therefore, how to select a suitable terminal for the network, and then how to select a suitable data bearer configuration SDT for a terminal, and how to properly set each threshold and allocate wireless transmission resources reasonably without reducing the efficiency of network resource usage are urgent problems to be solved. technical problem. If the terminal selected to configure SDT or the data bearer is inappropriate, or the threshold parameters set are inappropriate, then using SDT to transmit data will not only fail to obtain the expected benefits, but will be counterproductive, which may increase network resource consumption and signaling overhead, and increase Terminal power consumption. Therefore, this paper proposes a small data transmission information collection method and system to solve the above problems.

更进一步的，由于信道条件较差或需传输的数据量较大等原因，直到SDT操作定时器超时，UE仍未传输完成这些数据，则UE判定SDT传输过程失败，记录此时测量的当前小区RSRP值，及进行数据传输的上行载波。Further, due to poor channel conditions or a large amount of data to be transmitted, until the SDT operation timer expires, the UE has not completed the transmission of these data, then the UE determines that the SDT transmission process has failed, and records the current cell measured at this time RSRP value, and uplink carrier for data transmission.

本实施例提供如图1所示的一种小数据传输信息收集方法，包括以下步骤：This embodiment provides a method for collecting small data transmission information as shown in Figure 1, comprising the following steps:
S1对UE侧进行SDT配置并应用到对应的DRB承载，UE进入非激活态，当DRB承载有数据要发送且满足阈值条件时，UE触发SDT传输；S1 configures SDT on the UE side and applies it to the corresponding DRB bearer, the UE enters the inactive state, and when the DRB bearer has data to be sent and meets the threshold condition, the UE triggers SDT transmission;

本实施例UE记录的SDT传输失败相关的日志信息包括：The log information related to the SDT transmission failure recorded by the UE in this embodiment includes:
UE从网络接收的SDT配置；The SDT configuration received by the UE from the network;
SDT传输失败时的小区ID及测量的RSRP值；Cell ID and measured RSRP value when SDT transmission fails;
UE进行SDT传输所选择的上行载波；The uplink carrier selected by the UE for SDT transmission;
触发本次SDT传输的DRB承载的5G QoS标识；The 5G QoS identifier carried by the DRB that triggered this SDT transmission;
触发本次SDT传输的DRB承载待传输的上行数据量；The DRB that triggered this SDT transmission bears the amount of uplink data to be transmitted;
UE进行SDT传输所使用的上行资源，包括4步或2步RA preamble,PRACH及PUSCH时频域资源位置；Uplink resources used by UE for SDT transmission, including 4-step or 2-step RA preamble, PRACH and PUSCH time-frequency domain resource locations;

SDT传输过程中UE的平均移动速度；The average moving speed of UE during SDT transmission;
SDT传输失败时的时间戳。The timestamp when the SDT transmission failed.
本实施例方法应用在小数据传输(SDT)过程中，若传输失败，非激活态UE需记录相关日志信息，当该UE再次进入连接态时，要将所述日志信息上报给网络，网络基于收集的大量SDT传输失败相关的信息，可对配置SDT的目标终端和目标承载类型进行优化调整，并对当前的SDT配置参数进行优化改进，进而实现SDT传输功能的最优化。The method of this embodiment is applied in the small data transmission (SDT) process. If the transmission fails, the UE in the inactive state needs to record relevant log information. When the UE enters the connected state again, the log information should be reported to the network. The network based on A large amount of information related to SDT transmission failures collected can optimize and adjust the target terminal and target bearer type of SDT configuration, and optimize and improve the current SDT configuration parameters, thereby realizing the optimization of SDT transmission function.
实施例2Example 2
本实施例提供一种UE侧处理的方法，具体如下：当UE从连接态转移到非激活态时，接收到网络发送的RRCRelease消息，在消息中包含SDT配置信息，UE保存接收的SDT配置，并将SDT配置应用到对应的DRB承载。This embodiment provides a UE-side processing method, which is specifically as follows: when the UE transfers from the connected state to the inactive state, it receives the RRCRelease message sent by the network, contains SDT configuration information in the message, and the UE saves the received SDT configuration, And apply the SDT configuration to the corresponding DRB bearer.
本实施例DRB承载用户面数据，根据Qos不同，UE与5G基站之间可能最多建立8个DRB。In this embodiment, the DRB carries user plane data. According to different Qos, a maximum of 8 DRBs may be established between the UE and the 5G base station.
本实施例中SDT配置时设定数据量阈值，其中数据量阈值依据当前小区的实际传输情况自行设定。In this embodiment, the data volume threshold is set during SDT configuration, wherein the data volume threshold is set according to the actual transmission situation of the current cell.
在某一时刻，UE配置了SDT特性的DRB承载上有数据要发送，待传输的数据量少于SDT配置中的数据量阈值，且UE测量到当前小区的RSRP值高于SDT配置中的RSRP阈值，则UE触发SDT传输，并启动SDT操作定时器。At a certain moment, the UE has data to be sent on the DRB bearer configured with the SDT feature, the amount of data to be transmitted is less than the data amount threshold in the SDT configuration, and the RSRP value of the current cell measured by the UE is higher than the RSRP in the SDT configuration threshold, the UE triggers SDT transmission and starts the SDT operation timer.
本实施例的定时器脉冲时间间隔1微秒。通过外接12M晶振(11.0592MHZ)实现，其对应换算关系为12MHZ/12＝1MHZ＝1000000次/秒＝1000000次/1000000微秒＝1次/1微秒＝1指令/1微秒。定时器晶体每震荡1次就产生1个脉冲，花费1微秒，执行一次指令。The time interval of the timer pulse in this embodiment is 1 microsecond. Realized by connecting an external 12M crystal oscillator (11.0592MHZ), the corresponding conversion relationship is 12MHZ/12=1MHZ=1000000 times/second=1000000 times/1000000 microseconds=1 time/1 microsecond=1 command/1 microsecond. The timer crystal generates a pulse every time it oscillates, and it takes 1 microsecond to execute an instruction.
因此本实施例的定时器时间概念是根据脉冲数量得出来的。1脉冲＝1微秒＝1机器周期＝1指令。Therefore, the concept of timer time in this embodiment is obtained according to the number of pulses. 1 pulse = 1 microsecond = 1 machine cycle = 1 instruction.
需要指明的是，由于信道条件较差或需传输的数据量较大等原因，直到SDT操作定时器超时，UE仍未传输完成这些数据，则UE判定SDT传输过程失败，记录此时测量的当前小区RSRP值，及进行数据传输的上行载波。It should be pointed out that due to poor channel conditions or a large amount of data to be transmitted, until the SDT operation timer expires and the UE has not completed the transmission of these data, the UE will determine that the SDT transmission process has failed and record the current value measured at this time. The RSRP value of the cell, and the uplink carrier for data transmission.
本实施例UE记录进行SDT传输的DRB承载的QoS标识，及需传输的数据量大小；若UE执行的是RA-based SDT，则记录在随机接入过程中选择的preamble和PRACH资源位置，以及发送初始上行数据所使用的PUSCH资源位置。In this embodiment, the UE records the QoS identifier carried by the DRB for SDT transmission, and the amount of data to be transmitted; if the UE performs RA-based SDT, it records the preamble and PRACH resource locations selected during the random access process, and The PUSCH resource location used for sending initial uplink data.
本实施例UE记录初始上行传输的重传次数，及初始传输完成后的后续上行传输次数；基于定位信息得到当前的移动速度，并记录。In this embodiment, the UE records the number of retransmissions of the initial uplink transmission and the number of subsequent uplink transmissions after the initial transmission is completed; obtains the current moving speed based on the positioning information, and records it.
本实施例在SDT操作定时器超时后，UE可能进入空闲态，也可能保持在非激活态，在后续某个时刻，UE恢复或建立RRC连接，进入连接态后，将其记录的前一次SDT传输失败的日志信息上报给网络，进而完成UE侧的处理。In this embodiment, after the SDT operation timer expires, the UE may enter the idle state, or may remain in the inactive state. At a certain point in the future, the UE resumes or establishes an RRC connection.
