上行数据的传输方法、装置、系统和计算机存储介质
本申请基于申请号为201710056523.1、申请日为2017年01月25日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本发明涉及通信领域，尤其涉及一种上行数据的传输方法、装置、系统和计算机存储介质。
背景技术
第五代移动通信技术(fifth generation，简称5G)NR技术作为3GPP选定的和制定的下一代移动通信技术标准。提出了增强移动宽带EMBB,高可靠低时延传输URLLC，增强机器类型通讯EMTC等三个场景的应用，并且针对不同场景的需求对蜂窝移动通信的物理层,媒体访问控制(Media Access Control，简称MAC)层，无线链路控制(Radio Link Control，简称RLC)层和无线资源控制(Radio Resource Control，简称RRC)/分组数据汇聚协议(Packet Data Convergence Protocol，简称PDCP)进行设计和改进。为了满足EMTC场景中针对一定区域内超大数量的终端的数据通信和EMTC终端的低能耗低时延的技术要求；3GPP RAN1提出了基于无授权上行传输GRANT-free的上行传输的技术，该技术利用系统分配的专用资源不需要网络侧针对每次数据上传分配专门的上行资源进行上行传输。同时GRANT-free的上行传输在终端处于去激活INACTIVE状态上进行数据传输，不需要保持终端一直处于连接状态也不需要终端针对小数量的数据上传通过复杂的信令从inactive状态进入连接态。
GRANT-FREE技术的引入，大大降低了EMTC终端的上行数据的传 输的信令复杂，延迟时间，和功率消耗.但是GRANT-FREE技术的数据上传由于是在非链接态进行的数据上传，但是这种数据上传存在着传输失败率高、传输可靠性低的问题。
发明内容
本发明实施例提供了一种上行数据的传输方法、装置及系统，期望解决相关技术中缺少基于GRANT-FREE技术的数据传输的成功率低和/或可靠性低的问题。
根据本发明的一个实施例，提供了一种上行数据的传输方法，包括：判断终端发送上行传输数据的次数是否大于或者等于预定阈值；在判断结果为是的情况下，向网络侧设备发送建立无线连接的建立请求或者恢复无线连接的恢复请求。
根据本发明的另一个实施例，提供了一种上行数据的传输装置，包括：第一判断模块，配置为判断终端发送上行传输数据的次数是否大于或者等于预定阈值；第一处理模块，配置为在判断结果为是的情况下，向网络侧设备发送建立无线连接的建立请求或者恢复无线连接的恢复请求。
可选地，所述第一处理模块还配置为在判断结果为否的情况下，向所述网络侧设备发送上行传输数据。
可选地，所述装置还包括：第二判断模块，配置为判断是否接收到所述网络侧设备发送的所述上行传输数据对应的确认指示；第二处理模块，配置为在判断结果为是的情况下，将所述上行传输数据的次数初始化；在判断结果为否的情况下，继续判断所述上行传输数据的次数是否大于预定阈值。

根据本发明的又一个实施例，还提供了一种存储介质。该存储介质设置为存储配置为执行上述任意一个或多个技术方案提供的上行数据的传输方法。
在本发明实施例中，通过对终端发起上行传输数据的次数进行计数并根据该次数判断是否需要向对应的网络侧设备发送建立无线连接的建立请求或者恢复无线连接的恢复请求。因此，可以解决相关技术中缺少基于GRANT-FREE技术且有效可靠的终端数据上传的方法问题，从而达到了终端在数据上传时可靠有效、且能够在大量数据需要传输或者网络状态差时仍能够稳定上传的有益效果。

具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
研究发现，在利用GRANT-free等非授权上行资源(例如，这些非授权上行资源在使用之前，无需每次都有网络侧设备例如基站等进行分配或调度，终端设备就可以直接使用，例如，基于竞争机制直接使用的时频资源等)发送数据时，由于没有建立可靠的数据连接，没有基于连接传输数据进而会导致数据传输失败，进而导致数据传输可靠性低的问题。尤其是， 终端处于同一时刻大量终端需要上传数据或者网络状况较差的情况，就会造成终端多次上传无法成功的情况。因此，对于相关技术中的GRANT-FREE技术，缺少一种有效可靠的终端数据上传的方法。有鉴于此，在本发明实施例中，首先会统计出同一终端内终端利用非授权上行资源(例如，所述GRANT-free资源)重复发送同一个待上传的上行数据的次数，若该次数达到指定的预定阈值，则与网络从设备建立无线连接，这种无线连接可为重新建立的无线连接，或恢复的旧的无线连接，以方便继续终端后续的数据可以通过无线连接进行数据传输，以提高后续数据传输的成功率及数据传输的可靠性。以下结合具体实施例及附图对本发明的技术方案做进一步的说明和解释，但是以下仅是可选的实施例，但并不构成对本发明的不当限定。
实施例1
本申请实施例一所提供的方法实施例可以在移动终端、计算机终端或者类似的运算装置中执行。以运行在终端上为例，图1是本发明实施例的一种上行数据的传输方法的移动终端的硬件结构图。如图1所示，终端10可以包括一个或多个(图中仅示出一个)处理器102(处理器102可以包括但不限于微处理器MCU或可编程逻辑器件FPGA等的处理装置)、用于存储数据的存储器104、以及用于通信功能的传输装置106。本领域普通技术人员可以理解，图1所示的结构仅为示意，其并不对上述电子装置的结构造成限定。例如，终端10还可包括比图1中所示更多或者更少的组件，或者具有与图1所示不同的配置。
存储器104可配置为存储应用软件的软件程序以及模块，如本发明实施例中的上行数据的传输方法对应的程序指令/模块，处理器102通过运行存储在存储器104内的软件程序以及模块，从而执行各种功能应用以及数据处理，即实现上述的方法。存储器104可包括高速随机存储器，还可包 括非易失性存储器，如一个或者多个磁性存储装置、闪存、或者其他非易失性固态存储器。在一些实例中，存储器104可包括相对于处理器102远程设置的存储器，这些远程存储器可以通过网络连接至终端10。上述网络的实例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。
传输装置106配置为经由一个网络接收或者发送数据，可对应于网络接口、收发天线等各种通信接口。上述的网络可包括终端10的通信供应商提供的无线网络。在一个实例中，传输装置106包括一个网络适配器(Network Interface Controller，NIC)，其可通过基站与其他网络设备相连从而可与互联网进行通讯。在一个实例中，传输装置106可以为射频(Radio Frequency，RF)模块，其用于通过无线方式与互联网进行通讯。
在本实施例中提供了一种运行于上述终端的上行数据的传输方法，图2是根据本发明实施例的一种上行数据的传输方法的流程图，如图2所示，该流程包括如下步骤：
步骤S202，判断终端发起上行传输数据的次数是否大于或者等于预定阈值；
可选地，上行数据的传输处于空闲态(idle)或者连接非激活态(connect-inactive)，同时上行数据至少包括：非调度上行传输数据。这里的非调度上行传输数据，可为利用非网络侧调度的资源(即上述非授权资源)传输的数据。
在一种应用场景中，终端发起上行传输数据的次数为：上传同一个上行数据的次数。例如，终端A与数据B需要发送，在本发明实施例中，所述终端A发起上行传输数据B的次数，即传输同一个数据的次数。在本实施例中，终端反复上传一个数据，表示该数据很重要，需要尽快的使其上传成功并确保可靠性，故在本实施例中会请求建立无线连接。
在另一种实施例中，还可为在预设时间范围内对上传不同数据的总次 数。在该应用场景中说明终端在较短时间内有很多数据需要上传，为了确保数据的上传成功率和可靠性，可以建立无线连接。
需要指出的是，上述预定阈值是网络侧设备通过配置所确定的阈值，同时该阈值通过携带在系统消息或者专用信令中由网络侧设备发送至终端的。
步骤S204，在判断结果为是的情况下，向网络侧设备发送建立无线连接的建立请求或者恢复无线连接的恢复请求。
在本实施例中，建立的无线连接可用于后续终端与网络侧设备的数据交互，例如，用于所述终端上行数据的发送。该无线连接可利用授权上行资源进行数据传输，从而确保了终端需要上传数据的可考性。所述授权上行资源可为：需要网络侧设备进行资源调度分配之后，终端才可以使用的通信资源。所述通信资源可包括：时域资源、频域资源、还有各种通信码等用于通信的资源。典型的所述共享上行资源可包括：所述GRANT-free技术提供的非授权资源。
可选地，在判断结果为否的情况下，向所述网络侧设备发送上行传输数据。在本实施例中，若判断结果为否，且所述终端还有待发送的上行数据，可以继续使用所述非授权上行资源发送所述上行数据。若所述判断结果为否，且所述终端没有了待发送的上行数据，则等待到当前计时周期终止之后自动清零终端发起上行传输数据的次数。
可选地，在向所述网络侧设备发送上行传输数据之后，判断是否接收到所述网络侧设备发送的所述上行传输数据对应的确认指示，在判断结果为是的情况下，将所述上行传输数据的次数初始化；在判断结果为否的情况下，继续判断所述上行传输数据的次数是否大于预定阈值。
需要指出的是，初始化包括但不限于：将上行传输数据的次数清零。当然，将上行传输数据的次数调整至不等于零指定数值，或者恢复到接收 某一时间区间段内的第一次发送上行传输数据时的次数也在本实施例的保护范围以内。
可选的，在向所述网络侧设备发送上行传输数据时，增加所述终端发送所述上行传输数据的次数。
可选的，在判断没有接收到所述网络侧设备发送的所述上行传输数据对应的确认指示后，增加所述终端发送所述上行传输数据的次数。
可选地，增加所述终端发送所述上行传输数据的次数需要根据实际情况而定。例如，在网络正常的情况下，终端只会发起一次上行传输数据，因此，此时增减的次数的数值为1。
然而，如果在通信网络不正常或者终端发送故障时，终端可能会发生发送上行传输数据失败，为了不影响整个流程的进行，此时终端会默认增减的次数的数值为0。
可选地，当所述网络侧设备接收到所述终端发送的上行传输数据为调度上行传输时，所述确认指示为所述网络侧设备正确解码后发送的确认指示。
可选地，在在向网络侧设备发送建立无线连接的建立请求或者恢复无线连接的恢复请求之后与所述网络侧设备建立无线连接；利用所述无线连接的信令资源承载(Singling Resource Bearer，SIB)和/或数据资源承载(Data Resource Bearer，DRB)向所述网络侧设备发送上行数据。
可选地，该建立请求至少包括但不限于：无线资源控制连接建立请求。该恢复请求至少包括但不限于：无线资源控制连接恢复请求。
可选地，该建立请求或者恢复请求还可以携带非上行调度传输中未能成功发送到所述网络侧设备的数据。
此外，在本实施例当中，还提供了如下的场景，以便于理解本实施例 中所记载的技术方案。
场景一：
预定阈值为20，同时在向所述网络侧设备发送上行传输数据时，增加发送上行传输数据的次数，此外，初始发送上行传输数据的次数为0。
图3是根据本发明实施例的场景一对应的上行数据的传输方法的流程图。如图3所示，步骤包括：
S302，当终端上层应用需要发送上行传输数据时，发送一次上行传输数据，同时将发送上行传输数据的次数增加1次。
S304，终端判断是否从网络侧设备接收到发送上行传输数据对应的确认指示。
S306，如果终端接收到确认指示，则重置发送上行传输数据的次数为0。
S308，如果终端没有接收到确认指示，则判断当前发送上行传输数据的次数是否大于或者等于20。如果小于20的话，则跳转到步骤S302,重新进行循环。
S310，如果终端发送上行传输数据的次数是否大于或者等于20的话，终端则向网络侧设备发送无线建立请求。同时在于网络侧设备建立请求后，向网络侧设备发送上述数据。
网络侧设备在接收到该建立请求后，与终端建立无线连接，并接收发送的上行传输数据。
场景二：
预定阈值为20，同时在向所述网络侧设备发送上行传输数据时，增加发送上行传输数据的次数，此外，在时刻t时，初始发送上行传输数据的次数为N(N＜20)。
图4是根据本发明实施例的场景二对应的上行数据的传输方法的流程图。如图4所示，步骤包括：
S402，当终端上层应用需要发送上行传输数据时，发送一次上行传输数据。
S404，终端判断是否从网络侧设备接收到发送上行传输数据对应的确认指示。
S406，如果终端接收到确认指示，则重置回在t时刻的发送上行传输数据的次数为N。
S408，如果终端没有接收到确认指示，将发送上行传输数据的次数增加1次。
S410，判断当前发送上行传输数据的次数是否大于或者等于20。如果小于20的话，则跳转到步骤S402,重新进行循环。
S412，如果终端发送上行传输数据的次数是否大于或者等于20的话，终端则向网络侧设备发送无线恢复请求。同时在于网络侧设备恢复请求后，向网络侧设备发送上述数据。
网络侧设备在接收到该恢复请求后，恢复与终端的无线连接，并接收发送的上行传输数据。
需要指出的是，任何基于本发明实施例思路的场景均在本发明的保护范围之内。例如，上述举例的场景中终端与网络侧恢复无线连接同样也适用于场景一中的方案，同理，终端与网络侧建立无线连接同样也适用于场景二的方案。
通过上述步骤，解决了相关技术中缺少基于GRANT-FREE技术且有效可靠的终端数据上传的方法问题，从而达到了终端在数据上传时可靠有效、且能够在大量数据需要传输或者网络状态差时仍能够稳定上传的有益效 果。

工业实用性
