  • the embodiments of the present invention relate to the field of communications, and in particular, to a method, an apparatus, a system, and a terminal for transmitting data.
  • MTC Machine Type Communication
  • IOT Internet of Things
  • 3GPP has introduced the narrowband technology NB-IOT to provide extensive coverage. Support the access of massive MTC devices.
  • MTC devices come in a wide range, basic sensors and actuators. These devices are usually fixedly installed somewhere, report measurement information (such as temperature, humidity, pressure, etc.) according to the specified time, or perform some actions according to the instructions. Unlike conventional 3GPP services, MTC services have unique features:
  • Massive connection There are a large number of MTCs, and it is generally predicted that the number of connections is about 100 times that of smart terminals.
  • the amount of business data is very small.
  • the MTC service model that is currently reported by the 3GPP in the R13, the MTC service reported periodically is 20 bytes.
  • the content of monitoring data such as temperature and humidity is very small.
  • MTC chips The cost of MTC chips is generally very low. Considering the massive IoT devices and competing with wide-area wireless IoT technologies such as Lora, the cost is much lower than that of smart terminal chips. This means that the processing of the terminal must be as simple as possible, and the terminal capability is much lower than that of the conventional intelligent terminal.
  • MTC devices are typically battery powered and are expected to have a 10-year lifespan, ie no battery replacement for many years.
  • MTC devices are embedded in walls and basements, and are deployed in farms and forests. Compared with conventional smart terminals, wireless coverage is relatively poor.
  • 3GPP proposes a method to support MTC services by using NB-IOT narrowband technology. Because its bandwidth is relatively narrow, air interface resource scheduling granularity is smaller than LTE technology, so it has higher air interface resource utilization. It has a higher system capacity and a wider coverage.
  • NB-IOT technology Compared with LTE technology, NB-IOT technology has the following characteristics:
  • the coverage is very wide: in the same frequency band, eMTC (enhanced machine type communication) or NB-IOT is 20dB higher than LTE, the coverage is theoretically more than 100 times that of the LTE cell, so it can cover a wide area. .
  • the narrowband bandwidth makes the terminal more power efficient.
  • NB-IOT uses only 200k bandwidth, which requires less overhead for the physical layer processing of the terminal, thus saving power.
  • the terminal Compared with the 5M/10M bandwidth conventionally used by LTE, the terminal only needs to handle much smaller bandwidth, and its resource consumption is much smaller.
  • High-level signaling is optimized for small data transfers.
  • the CP ⁇ UP optimization mode is introduced, which reduces the signaling overhead of small data packet transmission.
  • the CP mode refers to the small data being transmitted in the NAS (Non-access stratum) PDU (Packet Data Unit);
  • the UP mode refers to the introduction of the bearer suspension and recovery mode to transmit small
  • the data in order to reduce the number of signaling, further saves power for the terminal, and also reduces the signaling processing load of the network.
  • a method of transmitting small data using a connectionless method is also proposed, that is, a method of transmitting a message containing small data without transmitting a Radio Resource Control (RRC) connection. More signal saving.
  • RRC Radio Resource Control
  • Co-site deployment is a common networking solution, in which multiple frequency points of a site are divided into multiple cells with different bandwidths to provide different coverage services.
  • the resource utilization of the narrowband cell may not be high.
  • the MTC service also has the feature of reporting infrequently. Even when the number of MTC users is relatively large, most of the MTC services may be in a dormant state.
  • the narrowband cell resources are relatively idle.
  • the smart terminal When the broadband cell load is relatively high, it is desirable to be able to use idle narrowband resources, but currently it is not possible to directly access the smart terminal into the narrowband cell. According to the current cell access rule, the smart terminal does not select the narrowband cell access as long as it can search for the available broadband cell; the narrowband cell resource cannot be used in the subsequent cell reselection or handover.
  • the utilization of the inter-cell spectrum resources can also be used to improve the utilization of the resources of the narrow-band cells, this method may affect the online service, such as dropped calls.
  • This method is also not flexible enough.
  • the network generally adjusts the frequency of the cell's frequency resources for a long period of time. It cannot be adjusted in time with the resource utilization in the cell. Therefore, there is still room for improvement in the resource utilization of the narrowband cell.
  • a broadband cell often has a coverage dead zone or a weak signal zone because its coverage is not large.
  • communication with the network cannot be performed, and even small data cannot be transmitted.
  • the signaling overhead is still relatively large.

  • the intelligent terminal When the intelligent terminal is in the coverage of the broadband cell, it keeps listening to the paging of the broadband cell.
  • the downlink paging interval of a narrowband cell is generally long, and cannot respond to the downlink service requirement of the real-time service in time. Because the narrowband cell is mainly designed for the MTC service, and the MTC service is generally infrequent, the time interval between two small data transmissions may be very long. In the normal data reporting model considered in 3GPP R13, the minimum interval is 30 minutes. . In order to save power, the paging interval of the narrowband cell is generally configured to be relatively long. This time interval does not meet the needs of real-time business.

  • the load balancing strategy of broadband frequency points and narrowband frequency points in the base station also needs to be considered.
  • the broadband frequency point load is relatively large and the narrowband frequency point resources are relatively idle, it may be considered to equalize the intelligent terminal small data transmission to the narrowband cell, thereby achieving the effect of reducing the load by the broadband and making full use of the narrowband resources; otherwise, when the narrowband frequency point load is used If the load is not high and the bandwidth of the broadband is not high, it is not suitable for transmitting the intelligent terminal service in the narrowband cell, because the narrowband resource congestion will affect the MTC service transmission.

Description

传输数据的方法、装置及系统、终端 技术领域
本发明实施例涉及通信领域，具体而言，涉及一种传输数据的方法、装置及系统、终端。
背景技术
随着物联网业务的兴起，机器类通信MTC(Machine Type Communication)设备也叫IOT(Internet of Things)设备，最近几年蓬勃兴起，3GPP为此引入了窄带技术NB-IOT来提供广泛的覆盖，以支持海量MTC设备的接入。
MTC设备范围很广，基本的是传感器和执行器。这些设备一般固定安装在某个地方，按照规定时间上报测量信息(例如温度、湿度、压力等)，也可以按照指令执行一些动作。和常规的3GPP业务不同，MTC业务具有独有的特性：
海量连接。MTC数量众多，一般预测其连接数量为智能终端的100倍左右。
业务数据量非常小。3GPP目前在R13中统计的MTC业务模型中，周期上报的MTC业务为20个字节。例如温度、湿度等监控数据的内容，都很少。
低成本。MTC芯片成本一般很低，考虑到海量物联网设备，以及和Lora等广域无线物联网技术相竞争，其成本远低于智能终端芯片。也就意味着，终端的处理必须尽量简化，终端能力远低于常规智能终端能力。
耗电量低。MTC设备一般是电池供电，期望10年寿命，即很多年内无需更换电池。
连接发起不频繁。像温度测量用传感器，可能半个小时或者十分钟才上报一次；而像湿度传感器，可能一天上次一次即可。
覆盖比较差。很多MTC设备嵌入到墙里、地下室，设置部署在农场、森林中，和常规智能终端相比，无线覆盖比较差。
3GPP目前为了支持这些物联网设备业务，提出了使用NB-IOT窄带技术来支持MTC业务的方法，因为其带宽比较窄，空口资源调度粒度比LTE技术更小，所以有着更高的空口资源利用率，其系统容量更高，覆盖范围更广。
和LTE技术相比，NB-IOT技术有如下特点：
1,覆盖非常广泛：在同样的频段下，eMTC(增强型的机器类通信)或者NB-IOT比LTE高20dB，覆盖范围理论上是LTE小区的100多倍多，所以可以覆盖很广的区域。
窄带带宽使得终端比较省电。
和LTE很宽的带宽相比，NB-IOT仅使用200k带宽，对终端物理层处理的开销要求少，从而非常省电。和LTE常规使用的的5M/10M带宽相比，终端仅仅需要处理小得多的带宽，其资源消耗小很多。
高层信令为小数据传输进行了优化。
3GPP R13中，考虑到海量终端的信令冲击可能影响网络安全，对终端耗电也比较大，需要优化，因此引入了CP\UP优化模式，减少了小数据包发送的信令开销。CP模式是指将小数据在NAS(Non-access stratum，非接入层)PDU(Packet Data Unit，分组数据单元)中随路传输；UP模式是指引入承载的挂起和恢复模式来传输小数据，以此减少信令的条数，进一步为终端省电，同时也减少了网络的信令处理负荷。
在最新的5G研究中，也提出了使用无连接方式发送小数据的方法，即无需建立无线资源控制(Radio Resource Control，简称为RRC)连接，仅发送一条包含小数据的消息来传输的方法，更加节省信令。
共站点部署是一个普遍的布网方案，即一个站点的多个频点划分为多个带宽不同的小区，来分布提供覆盖不同的服务。
当MTC业务部署初期的适合，窄带小区的资源利用率可能不高；此外，MTC业务也有不频繁上报的特性，即使MTC用户数量比较多的时候，可能大部分MTC业务都处于休眠状态，也会导致窄带小区资源比较空闲。
当宽带小区负荷比较高时，希望能够使用空闲的窄带资源，但是目前不能直接将智能终端接入到窄带小区中。根据目前的小区接入规则，智能终端只要能够搜索到可用的宽带小区，就不会选择窄带小区接入；后续的小区重选或者切换时，都不能使用窄带小区资源。
虽然也可以通过调整小区间频谱资源的方式来提升窄带小区资源的利用率，不过这种方式会对在线业务有影响，例如掉线等。此种方式也不够灵活，网络对小区频点资源的调整一般周期比较长，不能随着小区内资源利用率及时的调整，所以窄带小区的资源利用率还是存在提高空间。
相关技术中，宽带小区由于其覆盖范围并不大，经常存在覆盖盲区或者弱信号区，智能终端处于此种区域时，则无法和网络通讯，即使小数据也无法发送。信令开销依然比较大。目前智能终端发送小数据时，仍然需要RRC连接。
针对相关技术中存在的上述问题，目前尚未发现有效的解决方案。

实施例3
本实施是根据本发明的可选实施例，用于结合具体的场景对本申请进行详细说明：
本实施例考虑到智能终端(如手机)并不总是处于大数据业务中，在相当多的时间内，也具有小数据(如MTC数据)、海量连接的MTC业务 特性，或者当前仅有窄带小区覆盖的情况，本文充分探讨了利用NB-IOT/eMTC这样的窄带技术来实现智能终端小数据传输方法，以期为智能终端增强覆盖、提升系统资源的利用率，从而实现改善用户体验，以及提升无线系统容量。
为了支持智能终端的小数据业务在窄带频点传输，本实施例提出了一种数据传输方法、装置及系统，实现了使用窄带频点传输智能终端小数据。
当智能终端同时存在宽带小区覆盖和窄带小区覆盖时，智能终端灵活使用窄带空口传输小数据的具体方案如下：
智能终端从基站获取共站点的窄带小区信息。获取方式有多种，包括：
第一种方式：基站在小区广播中新增窄带小区信息。例如在宽带的广播消息中新增其共站点的窄带小区信息，包括用于终端接入到窄带小区所必须的信息，例如频点等信息。
第二种方式：基站通过RRC信令将窄带小区信息发送给智能终端。智能终端接入到宽带小区之后，如果具备窄带空口技术传输小数据的能力，则可以通过RRC信令向基站请求发送窄带小区信息，基站根据终端能力和请求内容进行选择性的发送。
进一步的，智能终端通过上行信元向基站表示其具备窄带空口传输数据能力，指示方式有多种，包括：
方式1：3GPP通过终端类型来约定该类型或者更高类型的智能终端支持窄带空口传输能力。
方式2：智能终端接入宽带小区时，通过上行RRC消息新增信元来指示该终端是否支持窄带空口传输数据能力。
上行RRC消息包括但不限于以下消息：RRC Connection Reconfiguration Complete、RRC Connection Reestablishment Complete、RRC Connection Reestablishment Request、RRC Connection Request、RRC Connection Setup Complete、UL Information Transfer、UE Information Response，或者新增上行空口消息等。
当智能终端处于有宽带小区的覆盖范围时，保持侦听宽带小区的寻呼。
窄带小区的下行寻呼间隔周期一般比较长，不能及时响应实时业务的下行业务需求。因为窄带小区主要是为MTC业务设计的，而MTC业务一般是不频繁的，两次小数据传输的时间间隔可能会很长，3GPP R13中考虑正常的数据上报模型中，时间间隔最小为30分钟。为了给其省电，窄带小区的寻呼间隔时间一般配置比较长。这个时间间隔无法满足实时业务的需求。
考虑到智能终端首先要保证高优先级业务的Qos保障，尤其是实时业务的时延要求，其寻呼依然保持宽带的寻呼机制，使得终端可以及时响应下行业务传输需求。
决策智能终端的哪些业务适合使用窄带空口传输的决策机制。
对于智能终端中哪些业务适合使用窄带空口传输的决策可以综合考虑这些因素：终端能力、同站点是否存在窄带小区配置、当前有没有其他业务、当前业务的时延要求、当前业务数据量大小、当前业务是否实时业务等业务Qos特性，以及小区负荷情况综合决策。
此外，基站中宽带频点、窄带频点的负荷均衡策略也需要考虑。当宽带频点负荷比较大而窄带频点资源比较空闲时，可以考虑将智能终端小数据传输均衡到窄带小区，实现为宽带降低负荷、充分利用窄带资源的效果；反之，即当窄带频点负荷比较大而宽带频点负荷并不高时，则不适合将在窄带小区传输智能终端业务，因为会导致窄带资源拥塞影响MTC业务传输。
这个决策可以网络侧判决，也可以是终端自行判决，有多种方式，图6是根据本发明实施例的智能终端业务是否使用NB-IOT传输决策方法示意图，见图6所示，包括：
方式1：基站决策。
在智能终端对业务发起附着(Attach)流程中，核心网将业务的Qos(服务质量)信息传递给基站，基站决策该业务是否可以在窄带上传输， 并将决策结果在空口下行RRC消息中指示给UE。
该方式的优点是核心网协议变更小。eNodeb(基站)决定业务的空口使用模式，核心网无感知。
方式2：核心网决策。
在智能终端对业务发起附着(Attach)流程中，核心网根据终端能力、业务的Qos信息决策该业务是否可以在窄带上传输，并将决策结果在Attach Rsp消息中指示给UE。
该方式的优点是基站协议变更小。核心网决定业务的空口使用模式。
方式3：智能终端自行决策。
由智能终端自行决策当前业务是否使用窄带传输。
进一步的，OMCR(无线操作维护中心)可以配置适合窄带空口传输的速率门限、业务类型等信息；基站从OMCR获取后通过RRC信令或者广播信令配置给智能终端。智能终端有上述业务需要传输时，将当前业务的业务类型、速率门限等与之比较，如果符合窄带传输的条件则使用窄带传输。
智能终端使用无连接方式在窄带空口上传输小数据。
智能UE使用窄带空口传输数据时，不改变终端当前的RRC状态，使用无连接方式发送数据。
智能终端上行小数据传输。
当智能终端上行使用窄带发送小数据时，UE将小数据封装成NAS PDU IE。UE在空口发送无连接消息其中带入信元：待发送的小数据，发送给eNodeb。上述过程中，UE保持RRC状态不变。
进一步的，上述空口消息包括但不限于：UL information transfer，新增上行空口消息等。
基站的窄带小区实例收到该消息后，根据该终端的UE ID标记找到对应的宽带小区内建立的UE实例进行处理；UE实例收到后发送给核心网。 S1口承载对应也采用无连接方式或者公共S1承载方式，以此减少S1口信令开销。
核心网收到该消息后，对上行数据的解析同已有的CP模式处理。移动性管理实体(Mobile Management Entity，简称MME)对NAS data PDU进行完整性检测和解密，获取数据。使用eKSI and Sequence Number"IEs对数据解密和完整性检查。如果是IP业务数据，则需要进行基于ROHC的IP头解压缩。
智能终端下行小数据传输。
下行小数据发送也有多种方式可以考虑。
方式1：当终端同时存在宽带小区覆盖和窄带小区覆盖时，当核心网检测到有下行小数据需要传输给智能终端时，通过宽带空口发送给终端。
因为考虑对智能终端实时下行业务的良好支持，智能终端保持对宽带小区的寻呼侦听，而不侦听窄带小区寻呼。
所以，有下行数据需要传输时，仍然使用宽带空口进行传输。对于处于IDLE态的智能终端，可以考虑使用寻呼消息随路携带小数据的方式进行传输，减少RRC新建的信令开销；对于连接态的UE，则使用公共承载或者专用承载传输小数据。
方式1的优势是智能终端下行接收处理简单；不过下行空口无法利用窄带空口技术的优势。
方式2：智能终端同时侦听宽带小区寻呼和窄带寻呼：
核心网检测到有下行数据需要传输时，首先决策该业务是否适合使用窄带空口传输，如果合适的话，则使用S1口无连接消息随路携带小数据的方式传输给eNodeb。核心网将小数据封装成NAS PDU IE，下行无连接S1消息中带入信元：NAS data PDU IE，如果加密的话，带入eKSI and Sequence Number"IEs，并且发送S1口给eNodeb的窄带小区信息。
eNodeb的窄带小区收到该信息后，发送下行空口寻呼消息给UE， 其中带入NAS data PDU IE，如果加密的话，带入eKSI and Sequence Number"IEs。
UE侦听窄带小区的寻呼，从中解析小数据。UE对NAS data PDU进行完整性检测和解密，获取数据。使用eKSI and Sequence Number"IEs对数据解密和完整性检查。如果是IP业务数据，则需要进行基于ROHC(Robust Header Compression)的IP头解压缩。方式2的优势是下行也使用窄带空口技术进行传输，充分提高资源利用率；不过终端需要同时监听宽带寻呼和窄带寻呼，实现复杂度高，成本有所增加，而且耗电也会增加。
当智能终端当前仅有窄带小区覆盖时，智能终端退化为常规MTC终端接入到窄带小区，进行小数据传输，其和网络的通讯处理同常规MTC终端。
本文上述宽带技术，除了上述提到的宽带技术之外，也适用于其他使用宽带频点的空口技术，包括但不限于2G\3G、5G新宽带空口技术等；
本文上述窄带技术，除了上述提到的窄带技术之外，也适用于其他使用窄带频点的空口技术，包括但不限于5G新窄带空口技术等。
第一部分：智能终端获取窄带小区信息实施方法
图7是根据本发明实施例的典型共站部署场景示意图，参见图7：宽带小区和窄带小区共站点部署图示。HSS为归属用户服务器(Home Subscriber Server)。
考虑到一般情况下，无线网络中宽带小区和窄带小区一般都是共站点部署，典型场景如图：划出一小部分窄带低频带宽提供窄带小区覆盖，支持MTC业务；其余部分带宽用于宽带小区，支持大速率业务或者实时业务。
在同样的频段下，窄带小区的覆盖范围比宽带小区广。例如，NB-IOT窄带覆盖范围非常广。理论上，在同样的频段下，NB-IOT比LTE提升20dB。当智能终端接入到宽带小区时，一般同时有同覆盖的窄带小区。基于窄带 小区的广域覆盖特性，智能终端可以同时处于宽带小区和窄带小区的无线覆盖，从而可以灵活使用两种空口来传输数据，尤其是可以使用窄带小区来传输小数据。
智能终端获取窄带小区信息的方式的实施方法如下：
实施例1：宽带小区广播消息通知方式：
宽带小区广播信息中新增了共站点部署的窄带小区信息，包括但不限于频点、小区ID等。可选的，广播消息中也可以新增小数据使用窄带频点发送的一些门限参数(例如1K)，例如数据量门限参数等。
智能终端宽带小区广播中解析出窄带小区信息并且保存。
实施例2：RRC信令配置方式。基站通过RRC信令将窄带小区信息发送给智能终端。
智能终端接入到宽带小区时，如果该终端具备通过窄带空口技术传输数据的能力，则在RRC Request消息中带入该能力指示IE给基站；
基站收到后在RRC Setup消息中带入窄带小区信息给终端。
可选的，带入终端是否支持窄带空口能力的IE也可以携带在其他上行RRC消息中，例如：
智能终端使用窄带小区传输小数据实施方法如下：
优选实施例1：手机自带的记步仪上报其用户的跑步步数到运动监控中心。
当用户进行跑步锻炼时，通过手机自带的记步仪上报其用户的跑步步数到运动监控中心。
前提：终端已经从基站获取到了窄带小区信息以及使用窄带传输的速率门限为1K。
第一步：终端决策当前业务为适合使用窄带传输的小数据。
智能终端当前处于IDLE态。应用层有跑步记录仪产生的小数据(20BYTE)需要发送。终端判决该数据量小于窄带频点发送的数据量门 限，决定使用窄带空口发送。
第二步：终端使用窄带小区通过无连接方式发送小数据。
UE对窄带小区发起随机接入过程。
UE将小数据封装成NAS PDU IE。UE在空口发送无连接消息UL information transfer，其中带入信元：NAS data PDU IE，如果加密，则带入相应的加密信息：eKSI and Sequence Number"IEs。
UE发送该消息给基。
上述过程中，UE保持当前RRC状态不变。
第三步：基站收到后，解析出小数据，通过无连接消息发送给MME。
eNodeb从Uu口无连接消息中解析出NAS PDU。
发送S1口S1-AP INITIAL UE MESSAGE消息，其中带入信元：
NAS data PDU IE，eKSI and Sequence Number"IEs
上述过程中，eNodeb保持UE的RRC状态不变。
步骤4：MME解析上行数据：
MME对NAS data PDU进行完整性检测和解密，获取数据。
使用eKSI and Sequence Number"IEs对数据解密和完整性检查。
如果是IP业务数据，则需要进行基于ROHC的IP头解压缩。
优选实施例2：手机有一个天气预报APP，天气监控中心定时(间隔30分钟)给手机推送天气信息。
步骤1：基站部署了共站点的LTE小区和NB-IOT小区。LTE小区广播信息中新增了共站点部署的NB-IOT小区信息，包括频点、小区ID等。
广播消息中也新增小数据使用窄带频点发送的数据量门限：1K。
步骤2智能手机从LTE小区广播中解析出窄带小区信息并且保存。
步骤3：天气监控中心发送最新天气信息，500BYTE，给核心网；核心网发送给基站。
eNodeb收到后，判决当前业务为适合使用窄带传输的小数据，因为数据量为500BYTE，小于下行数据使用窄带传输的门限，决定使用窄带发送。
步骤4：eNodeb使用窄带小区下行寻呼消息传输下行数据。
eNodeb在窄带小区发送寻呼消息，其中带入下行小数据。eNodeb将小数据封装成NAS PDU IE。寻呼消息带入信元：
NAS data PDU IE，eKSI and Sequence Number"IEs
上述过程中，eNodeb保持UE的RRC状态不变。
步骤5：UE从窄带小区接收小数据。
UE侦听窄带小区的寻呼，从中解析小数据。
UE对NAS data PDU进行完整性检测和解密，获取数据。
使用eKSI and Sequence Number"IEs对数据解密和完整性检查。
如果是IP业务数据，则需要进行基于ROHC的IP头解压缩。
智能终端移动时窄带小区信息更新实施例。
智能终端移动时，如果接入的LTE小区发生改变，则终端从新接入的LTE小区获取最新的窄带小区信息。
方法1：广播消息通知方式：
终端读取最新接入的LTE小区广播信息，从中获取最新的共站点部署的NB-IOT小区信息。
方法2：RRC信令配置方式。基站通过RRC信令将窄带小区信息发送给智能终端。
智能终端移动到新的LTE小区之后，如果该终端具备窄带空口技术传输小数据的能力，则在RB reconfig消息或者RRC request消息中带入该能力指示IE；
基站收到后在RB reconfiguration complete或者RRC setup消息中带 入窄带小区信息给终端。
为了支持海量物联网终端设备，针对其海量、小数据、低成本的特性，3GPP R13引入了窄带技术NB-IOT进行支持，在5G研究中，对海量物联网设备支持的研究进一步深入加强。窄带技术在3GPP中应用将进一步增强，充分发挥其资源利用高、覆盖光的特性。
通过使用本发明所提出的小数据传输方法，可以实现智能终端的小数据业务在窄带频点传输，达到如下受益：
1，可以为智能终端增强覆盖。利用窄带小区覆盖范围广的特性，为智能终端扩大通讯区域，在那些没有宽带小区覆盖但是存在窄带小区覆盖的区域，智能终端依然可以和网络进行通讯。
可以提升系统的资源利用率，把窄带小区空闲资源充分利用。。考虑到MTC业务的不频繁传输特性，NB-IOT小区资源可能有空闲和空余，可以用于智能手机的数据传输，提升资源利用率。和调整频点的方法相比，本方法直接使用窄带资源，无需通过小区重配流程来调整频点的方法，对窄带资源的利用及时而且不影响在线业务，更有效的提升窄带资源利用率。
节省智能终端的信令开销。对智能手机的小数据传输，利用NB-IOT优化信令来节省网络侧信令开销。
为智能手机进一步省电。终端侧信令开销减少，藉此为终端省电。
