具体实施方式
下面对文中出现的一些词语进行解释：
1、本公开实施例所指的“物联网”是指通过射频识别(RFID)、红外感应器、全球定位系统、激光扫描器等信息传感设备，按约定的协议，把任何物品与互联网连接起来，进行信息交换和通讯，以实现智能化识别、定位、跟踪、监控和管理的一种网络。
2、本公开实施例所指的“物联网设备”是指能够连接该网络的设备，比如智能水表等。
3、本公开实施例所指的“网络侧设备”是指微基站、宏基站等。
4、本申请实施例中术语“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
由于物联网设备与网络侧设备之间通过随机接入过程建立数据链路产生的信令数量较多，对于部分只有小数据包交互需求的物联网设备，建立数据链路所占用的时频资源，甚至超过数据传输所需占用的时频资源，虽然物联网设备与网络侧设备之间不需要频繁发送数据，但物联网设备以其体量仍能造成巨大的信令开销。
综上所述，目前数据传输时产生的信令开销较多。
本发明实施例中提供了一种进行数据传输的方法，终端发起的随机接入流程中，若网络侧设备反馈了自身的随机接入请求，则在后续的随机接入过程中将待发送的小数据包通过后续的随机接入消息发送给网络侧设备，比如：终端接收到网络侧设备反馈的随机接入响应Msg2后，将小数据包置于Msg3 中，并根据Msg2指示的无线资源配置信息，比如时间提前量、时频位置和功控等参数将Msg3发送给网络侧设备，相较于在随机接入建立完成后再通过单独的上行资源传输该小数据包的方式，实现了小数据包的提前传输，节省了数据传输的信令开销。
下面结合说明书附图对本公开实施例做进一步详细描述。
如图1所示，一种数据传输的方法和设备，包括：物联网设备10和网络侧设备20。
物联网设备10：用于确定有需要上报的数据；在竞争随机接入过程中将数据发送给网络侧设备。
网络侧设备20：用于在竞争随机接入过程中接收物联网设备发送的数据；将接收到数据发送给MME。
通过上述方案，物联网设备与网络侧设备在竞争随机接入过程将需要上报的数据发送给网络侧设备，相应的，网络侧设备在竞争随机接入过程接收到物联网设备发送的数据后，将数据发送给MME进行数据处理。物联网设备与网络侧设备在发起数据传输时，在建立数据链路时要引入随机接入过程，随机接入过程包括竞争随机接入过程和非竞争随机接入过程，终端在竞争随机接入过程可以将需要上报的信息发送给网络侧设备，不需要在数据链路建立完成后再将需要上报的数据发送给网络侧设备，从而实现了提前将数据传输到网络侧设备，节省了用于单独传输需要上报的数据所产生的信令开销。
本公开实施例，物联网设备以及网络侧设备均处于未连接状态时，物联网设备通过在与网络侧设备建立数据连接时引入的竞争随机接入过程将需要上报的数据发送给网络侧设备。
物联网设备均处于未连接状态可以是，物联网设备与网络侧设备进行空口传输时所用到的Uu接口处于未释放状态；网络侧设备处于未连接状态可以是，网络侧设备与核心网设备MME进行数据传输时所用到的S1接口也处于未释放状态。
当处于未连接状态的物联网设备有需要上报的数据时，物联网设备进行 小区搜索，在接收到网络侧设备广播的系统信息后，物联网设备对接收到的网络侧设备广播的系统消息进行解码，并根据解码后的系统信息中的第二信息块(SIB2(System Information Block，系统信息块))中包含公共无线资源配置信息进行无线资源配置，之后通过竞争随机接入过程建立与物联网设备的数据连接。
本公开实施例中，物联网设备通过竞争随机接入过程将需要上报的数据发送给网络侧设备，可以将数据提前发送给网络侧设备，本公开可以通过下列两种方式实现提前传输，下面分别进行说明：
传输方式一：不进行可行性判断，直接将需要上报的数据通过上行数据发送给网络侧设备；
物联网设备不需要判断所述网络侧设备是否支持物联网设备提前传输数据，直接将需要上报的数据通过上行数据发送给网络侧设备，比如物联网设备通过竞争随机接入过程中的MSG1或MSG3将需要上报的数据发送给网络侧设备。
传输方式二：在确定能够进行提前传输后，再将需要上报的数据通过上行数据发送给网络侧设备；
物联网设备在发送数据前，在确定能够进行提前传输后，再将需要上报的数据通过竞争随机接入过程的上行数据发送给网络侧设备，所述物联网设备通过下列几方面内容判断当前是否能够进行提前传输：
判断内容一：需要上报的数据是否符合提前传输条件；
其中，判断数据是否能够进行提前传输的条件包括但不限于下列中的部分或全部：
数据条件一：需要上报的数据大小不大于数据阈值。
本公开实施例中，物联网设备通过竞争随机接入过程中的上行数据将需要上报的数据发送给网络侧设备，则需要上报的数据大小应不大于承载数据的上行数据的数据阈值。
比如，物联网设备通过竞争随机接入过程中的Msg3将需要上报的数据发 送给网络侧设备，则需要上报的数据大小要不大于Msg3所能承载的数据大小的数据阈值。
数据条件二：需要上报的数据为不敏感数据。
物理网设备不通过竞争随机接入过程将上报的数据发送给网络侧设备，而是在与网络侧设备的数据链路建立完成后再将需要上报的数据发送给网络侧设备，网络侧设备在建立数据链路的过程中会对接入的物联网设备进行安全性鉴权，在确认接入的物联网设备处于安全状态后，数据的传输过程更加安全，可以降低发生安全问题时带来的不良影响。
若物联网设备通过竞争随机接入过程将需要上报的数据发送给网络侧设备，网络侧设备还未对物联网设备进行安全性鉴权，因此数据的传输过程具有一定的安全隐患。
因此，若物联网设备要通过竞争随机接入过程将需要上报的数据发送给网络侧设备，则在发送数据前，物联网设备可以先判断需要上报的数据是否为敏感数据，若数据为敏感数据，则不通过竞争随机接入过程发送数据，以此降低数据传输过程中发生安全问题时带来的恶劣影响。
其中，物联网设备判断需要上报的数据是否为敏感数据的方式有多种，下面举例说明：
判断方式一：根据预先定义的敏感数据类型来判断。
比如，预先将用户的身份信息，位置信息等数据定义为敏感数据，则物联网设备在发送包含用户的身份信息，位置信息等数据时不通过竞争随机接入过程发送数据。
判断方式二：通过物联网设备内上层网络的决策机制来判断。
比如，在物联网设备的MAC层增加表示数据是否敏感的属性值，该属性值可以反映提前传输数据的敏感程度，若需要上报的数据的属性值为1时，表示所述数据为不敏感数据；若需要上报的数据的属性值为0时，表示所述数据为敏感数据。
通过MAC层的决策机制判断所述数据是否敏感，比如当前发送的数据包 含用户的性别信息，MAC层内的决策机制判断用户的性别信息在当前场景为敏感数据，则更改所述数据的属性值为0，终端根据属性值确定所述数据不符合提前传输的条件，可以不通过竞争随机接入过程将所述数据提前发送给网络侧设备。
相应的，终端在随机接入过程中选择不支持提前传输的前导码资源。
需要说明的是，上述MAC层仅为举例，可以通过NV或AT(Attention，注意)命令在任一协议层进行配置或修改该属性值。
判断内容二：网络侧设备是否支持提前传输；
网络侧设备广播的系统消息中，包括随机接入前导码的分配指示，所述物联网设备确定通过广播接收到来自所述网络侧设备的随机接入前导码的分配指示中包含提前传输的前导码资源。
若所述网络侧设备广播的随机接入前导码的分配指示包括提前传输的前导码资源，则物联网设备确定所述网络侧设备支持物联网设备提前传输数据；否则，物联网设备确定所述网络侧设备不支持提前传输数据。
比如，若以数字区间表示支持提前传输的随机接入码资源，假如支持提前传输的前导码资源的范围为1-20，网络侧设备广播的随机接入前导码的分配指示包括15-30，则物联网设备确定网络侧设备广播的随机接入前导码包含支持提前传输的前导码15-20，若所述物联网设备通过竞争随机接入过程将需要上报的数据发送给网络侧设备，则所述物联网设备可以在前导码15-20中选择一个作为前导码。
网络侧设备通过将随机接入前导码分为几个部分，用于分配指示不同的数据传输选择不同的前导码资源，下面对网络侧设备广播的随机接入前导码的分配指示进行举例介绍：
下面以网络侧设备广播的随机接收前导码的组成方式有多种，下面举例说明：
组成方式一：eMTC(LTE-Machine-to-Machine，增强机器类通信)的随机接入前导码组成。
如图2所示，本公开实施例提供的一种网络侧设备广播的eMTC的随机接入前导码的组成结构示意图。
对于eMTC的随机接入过程有两种：非竞争随机接入和基于竞争的随机接入，物联网设备若要通过随机接入过程将需要上报的数据发送给网络侧设备，必须通过竞争随机接入过程的上行数据来发送需要上报的数据。
相应的，eMTC的随机接入前导码组成为基于竞争的随机接入码资源A和基于非竞争的随机接入码资源B。其中，基于竞争的随机接入码资源A还可以再细分为支持提前传输的竞争码资源1和不支持提前传输的竞争码资源2。
组成方式二：NB-IoT(Narrow Band Internet of Things,窄带物联网)的随机接入前导码组成。
如图3所示，本公开实施例提供的一种网络侧设备广播的NB-IoT的随机接入前导码的组成结构示意图。
NB-IoT的物联网设备的传输方式有Multi-tone(多频音)和Single-tone(单频音)，随机接入过程为基于竞争的随机接入。NB-IoT的物联网设备若要通过竞争随机接入过程将需要上报的数据发送给网络侧设备，物联网设备必须支持Multi-tone传输方式。因此，当NB-IoT的物联网设备以随机接入前导码作为提示信息时，相应的，随机接入前导码组成应具备以下结构：
NB-IoT的物联网设备基于竞争的随机接入前导码组成结构为：Multi-tone码资源和Single-tone码资源。其中，Multi-tone码资源再细分为不支持数据提前传输码资源GroupNormal(正常组)和支持数据提前传输码资源GroupEDT(Group Early data transmission，提前传输组)。
物联网设备在确定需要上报的数据不符合上述提前传输条件时，则物联网设备在与网络侧设备的数据链路建立完成后再将需要上报的数据发送给网络侧设备；若物联网设备在确定需要上报的数据符合上述提前传输条件时，则物联网设备的数据可以通过竞争随机接入过程将需要上报的数据发送给网络侧设备。
本公开实施例中，物联网设备确定能够通过竞争随机接入过程将需要上 报的数据发送给网络侧设备后，通过提示信息通知网络侧设备，网络侧设备在确定物联网设备的传输方式后，为物联网设备配置相应的资源。
其中，物联网设备发送提示信息的方式有多种，下面举例说明：
提示方式一：将Msg1的随机接入前导码(preamble)作为提示信息。
物联网设备在随机过程中首先会向网络侧设备发送Msg1，则物联网设备可以将Msg1的随机接入前导码作为提示信息发送给网络侧设备。
下面根据物联网设备的不同类型和传输方式，对随机接入前导码的选择方式进行介绍：
选择方式一：请结合图2，物联网设备根据网络侧设备广播的随机接入前导码的分配指示信息选择支持提前传输的竞争码1作为提示信息发送给网络侧设备；否则，物联网设备根据具体情况选择相应的随机接入前导码。
如图4所示，本公开实施例提供的一种eMTC的随机接入前导码的选择方式的流程示意图，包括：
步骤400：物联网设备引入随机接入过程；
步骤401：物联网设备根据C-RNTI(Cell Radio Network Temporary Identifier，小区无线网络临时标识)判断与网络侧设备是否处于连接状态，如果是，则执行步骤402；否则，执行步骤403。
步骤402：物联网设备的Msg1的随机接入前导码选择非竞争码资源。
步骤403：物联网设备判断需要上报的数据是否满足提前传输的数据条件，如果是，则执行步骤404；否则，执行步骤405。
步骤404：物联网设备的随机接入前导码选择支持提前传输的竞争码资源；
步骤405：物联网设备的随机接入前导码选择不支持提前传输的竞争码资源。
其中，步骤401：对于eMTC，网络侧设备在应答物联网设备的服务请求时向物联网设备广播的系统消息中包含有分配给物联网设备的一个动态标识C-RNTI。
需要说明的是，处于连接状态的物联网设备才能够引入非竞争随机接入 过程，处于未连接状态的物联网设备才能够引入竞争随机接入过程。若物联网设备与网络侧设备处于连接状态时，C-RNTI为有效值；若物联网设备与网络侧设备处于未连接状态时，C-RNTI为无效值。因此，当C-RNTI为有效值，物联网设备确定与网络侧设备处于连接状态；否则，物联网设备确定与网络侧设备处于未连接状态。
选择方式二：请结合图3，若NB-IoT的物联网设备通过竞争随机接入过程将需要上报的数据发送给网络侧设备，则物联网设备要选择Multi-tone码资源内支持数据提前传输码资源GroupEDT作为提示信息发送给网络侧设备；否则，物联网设备根据具体情况选择相应的随机接入前导码。
如图5所示，本公开实施例提供的一种NB-IoT的随机接入前导码的选择方式的流程示意图，包括：
步骤501：NB-IoT的物联网设备引入随机接入过程；
步骤502：NB-IoT的物联网设备判断物联网设备是否支持Multi-tone传输方式，如果是，则执行步骤504；否则，执行步骤503；
步骤503：NB-IoT的物联网设备的随机接入前导码选择Single-tone码资源；
步骤504：NB-IoT的物联网设备判断需要上报的数据是否满足提前传输的数据条件，如果是，则执行步骤505；否则，执行步骤506；
步骤505：NB-IoT的物联网设备的随机接入前导码选择支持提前传输的码资源GroupEDT；
步骤506：NB-IoT的物联网设备的随机接入前导码选择不支持提前传输的竞争码资源GroupNormal。
需要说明的是，上述随机接入前导码的组成方式仅为举例，任何能够作为提示信息的随机接入前导码的组成方式都适用于本公开。
提示方式二：将Msg1中的二进制码作为提示信息。
在Msg1中增加或应用原有的至少1位二进制码数值作为提示信息，以二进制码的数值来区分通过竞争随机接入过程发送数据和不通过竞争随机接入 过程发送数据两种传输方式。
比如，在Msg1增加一位二进制码，二进制码的值等于0时，表示通过竞争随机接入过程发送数据；当二进制码的值等于1时，表示不通过竞争随机接入过程发送数据。
需要说明的是，上述方法仅为举例说明，二进制码可以作为Msg1中的独立部分也可以在随机接入前导码中增加一位二进制码以组合的方式在竞争随机接入过程通过Msg1发送给网络侧设备。
提示方式三：将承载Msg1的时频资源作为提示信息。
将物联网设备在竞争随机接入过程中用于发送Msg1的时频资源作为提示信息，可以通过时域资源的不同时隙或者子帧来区分；也可以通过频域资源的不同频率来区分；也可以将时域和频率结合来区分。
比如：将时域资源的一系统的前半部分子帧来承载通过竞争随机接入过程发送数据的Msg1；将时域资源的一系统的后半部分子帧来承载不通过竞争随机接入过程发送数据的Msg1。
本公开实施例中，网络侧设备检测到物联网设备发送的Msg1的随机接入前导码后，会在DL-SCH(Downlink share channel，下行共享信道)上发送一个响应，针对不同的随机接入前导码为物联网设备分配不同的UL grant(上行调度授权)，Preamble Index(随机接入前导码索引)，TA(Timing Advance，时间提前量)，临时C-RNTI，backoff(回退)等参数，并通过Msg2将上述参数通过竞争随机接入过程发送给物联网设备，以使物联网设备根据上述参数完成SRB(Signalling Radio Bearers，信令无线承载)1和无线资源配置信息。
需要说明的是，若网络侧设备接收到的Msg1的前导码确定物联网设备的数据传输方式为通过竞争随机接入过程将需要上报的数据发送给网络侧设备，实现了数据的提前传输。相应的，网络侧设备需要判断是否允许物联网设备提前传输，网络侧设备判断的依据有多种，下面从网络侧设备当前的网络负载和/或接入设备的数目两方面作为判断依据进行说明：
网络侧设备通过判断当前是否满足负载条件来确定是否允许物联网设备 提前传输，如果满足负载条件，则允许物联网设备提前传输；否则，不允许物联网设备提前传输。其中，负载条件包括下列条件中的部分或全部：
负载条件一：网络侧设备当前的负载小于负载阈值；
比如，设置的网络侧设备负载阈值为总负载的40％，网络侧设备当前的负载为总负载的90％，则网络侧设备确定当前负载超过负载阈值，不允许物联网设备提前传输。
负载条件二：网络侧设备当前接入的设备数量小于设备阈值。
比如，设置的网络侧设备接入的设备阈值为80，网络侧设备当前接入的设备数量为40，则网络侧设备确定当前接入的设备数量小于设备阈值，允许物联网设备提前传输。
若网络侧设备当前负载较大或接入设备数量较高时，可拒绝物联网设备提前传输的随机接入请求，并为物联网设备分配不允许通过竞争随机接入过程发送数据的上行调度授权，并通过竞争随机接入过程的Msg2发送给物联网设备。
网络侧设备通过竞争随机接入过程的Msg2将判断结果通知给物联网设备。
其中，网络侧设备将判断结果通知给物联网设备的方式有多种，下面举例说明：
通知方式一：通过Msg2中某二进制码通知。
网络侧设备将判断结果以二进制码的方式进行表示，比如，通过Msg2中的至少一位二进制码作为通知消息，当二进制码的数值等于0时，则网络侧判断结果表示当前满足负载条件，允许物联网设备提前传输；当二进制码的数值等于1时，则网络侧判断结果表示当前不满足负载条件，不允许物联网设备提前传输。
相应的，物联网设备根据网络侧设备发送Msg2中的二进制码的值判断网络侧设备的是否允许提前传输。
通知方式二：通过上行调度授权通知。
若网络侧设备判断结果为当前满足负载条件，则网络侧设备为物联网设备分配允许通过竞争随机接入过程发送数据的上行调度授权，以及为需要承载需要上报的数据的Msg3分配相应容量的资源块；否则，网络侧设备为物联网设备分配不允许通过竞争随机接入过程发送数据的上行调度授权。
相应的，物联网设备根据网络侧设备发送的Msg2中的上行调度授权判断网络侧设备的是否允许提前传输。
具体的，物联网设备通过下列方式判断接下来的数据传输过程能否通过MSG3将需要上报的数据发送给网络侧设备：
网络侧设备分配的上行资源是否能够传输包含需要上报的数据的Msg3；如果是，则确定网络侧设备允许提前传输；否则，确定网络侧设备不允许提前传输。
若物联网设备确定网络侧设备允许提前传输，则将需要上报的数据承载于Msg3中，发送给网络侧设备。
本公开实施例，物联网设备在接收到网络侧设备发送Msg2后，根据Msg2中RAR中包含的建立SRB1承载信息和无线资源配置信息完成SRB1承载，即建立与网络侧设备的RRC连接，以及无线资源配置。并根据Msg2的TA调整上行发送时机，向网络侧设备发送RRC Connection Complete(无线资源控制连接完成)消息，即Msg3，Msg3中会携带UE-ID(User Equipment-identification，用户设备号)和NAS(Non-Access Stratum，非接入层)PDU(Protocol Data Unit，协议数据单元)，NAS PDU包含信令及数据两部分，即Service Request(服务请求)消息和上行数据。
本公开实施例中，上述竞争随机接入过程，由于竞争随机接入过程本身即为尝试性接入过程，具有尝试次数的限制，若达到最大尝试次数，网络侧设备和物联网设备依旧没有建立数据连接，则尝试失败，需要网络侧设备调整发射功率后重新接入。
本公开实施例中，物联网设备通过竞争随机接入过程将需要上报的数据发送给网络侧设备时，有提前传输过程尝试次数限制，若物联网设备在竞争 随机接入过程中，没有接收到下行数据，则认为物联网设备和网络侧设备接入失败，重新发起竞争随机接入过程。
其中，接入失败的原因有多种，下面举例说明：
失败原因一：物联网设备未成功接收Msg2；
失败原因二：物联网设备发送Msg3失败，网络侧设备未接收到Msg3；
物联网设备向网络侧设备发送Msg3的方式是HARQ(ybrid Automatic Repeat Request，混合自动重传请求)，最大重传次数是RRC配置的承载在SIB2中，其中可针对提前传输时承载数据和不提前传输时的Msg3进行单独区分。
物联网设备发送Msg3后，会启动一个mac-ContentionResolutionTimer(竞争解决定时器)，并在Msg3进行HARQ重传时，重启该timer，若在最大重传次数内网络侧设备若未收到物联网设备发送的Msg3，则定时器超时，本次发送Msg3失败，尝试接入次数加1。
失败原因三：物联网设备未接收到Msg4。
下面对竞争随机接入过程中的可能出现的尝试次数累加情况进行举例说明：
比如，尝试次数以μ表示，且默认为0；提前传输的最大尝试次数为α，α＝2。若物联网设备欲通过竞争随机接入过程将需要上报的数据发送给网络侧设备，但物联网设备未接收到网络侧设备发送Msg2，则接入失败，尝试接入次数μ加1，此时μ＝1，同时物联网重新选择Msg1的随机接入前导码资源和时域资源发送给网络侧设备，在重新发起的这个过程，物联网设备成功接收Msg2，但未接收到Msg4，则接入失败，尝试接入次数μ加1，此时μ＝2，达到了提前传输的最大尝试次数α，则尝试次数以μ清零，物联网设备根据backoff参数等待一段时间后，发起不通过竞争随机接入过程传输数据的传输方式，并通过上述选择方式选择相应的随机接入前导码资源和时频资源，通过Msg1发送给网络侧设备。在重传时，若多次接入均失败，则可以通过提升发射功率的方式来增大接入成功的概率。
需要说明的是，提前传输的最大尝试次数可以通过网络侧设备广播的系统信息中的第二信息块中进行设置，并由网络侧设备根据当前网络负载对提前传输的最大尝试次数进行调整。
比如，当前网络侧设备当前的网络负载较高或接入的物联网设备较多，网络侧设备能够成功接入物联网设备的成功率就较低，则提前传输时的最大尝试次数可以调整到较大的数值；若当前网络侧设备当前的网络负载较低或接入的物联网设备较少，网络侧设备能够成功接入物联网设备的成功率就较高，则提前传输时的最大尝试次数可以调整到较小的数值；
本公开实施例中，若网络侧设备成功接收到物联网设备发送Msg3后，将直接选择MME透传数据，并将Service Request NAS消息封装在Initial UE Message(初始UE消息)发送给MME。
MME在接收到Service Request消息后，通过S1-AP(S1Application Protocol，S1应用协议)与网络侧设备建立了S1信令连接。并且将对NAS信令PDU进行解析，解析成功后将NAS PDU数据经S-GW(Serving GateWay，服务网关)发送给P-GW(PDN GateWay，PDN网关)。若MME未解析成功，则通知物联网设备重新发起随机接入过程。
MME将上行数据经S-GW发送给P-GW，数据传输完成后MME触发S1连接释放过程。
