随着智能传感器的发展，越来越多具有通信能力的设备，例如智能摄像头、智能监控器等非传统终端设备可以接入网络，并且发生数据通信。这种类型的通信设备的数据通信具有传输数据量小(主要是一些数据上报)、数据传输不频繁(定时上报或者突发性数据上报)的特点，这一类的终端被称为移动物联网(CIoT，Cellular Internet of Things)终端。传统的EPS由于主要针对持续发送大量数据的终端，因此，设计了复杂的空闲态和连接态的转化，即终端在连接态可以传输数据，不传输数据就进入空闲态(IDLE)。这种机制保证通信的高可靠和有效性。然而，当CIoT终端接入传统的EPS后，导致CIoT终端通过复杂的空闲态和连接态转化流程传输很少量的数据。如此，造成了信令浪费，增加了网络负荷。With the development of smart sensors, more and more communication-capable devices, such as smart cameras, smart monitors, and the like, can access the network and data communication occurs. The data communication of this type of communication device has the characteristics of small amount of transmission data (mainly some data reporting), infrequent data transmission (timed reporting or bursty data reporting), and this type of terminal is called mobile internet of things. (CIoT, Cellular Internet of Things) terminal. Since the traditional EPS is mainly for terminals that continuously transmit a large amount of data, a complex idle state and a connection state transition are designed, that is, the terminal can transmit data in the connected state and enter the idle state (IDLE) without transmitting data. This mechanism guarantees high reliability and effectiveness of communication. However, when the CIoT terminal accesses the traditional EPS, the CIoT terminal transmits a small amount of data through the complex idle state and connected state conversion process. As a result, signaling is wasted and network load is increased.
针对CIoT终端的特殊性，CIoT终端可以接入如图2所示的网络架构。如图2所示，移动物联网终端(CIoT UE)为频繁或者不频繁传输小数据包的物联网终端；移动物联网无线接入网(CIoT RAN)和移动物联网分组核心网(CIoT EPC)为CIoT的专用网络，采用简化的或者增强的EPS相关功能(移动管理和会话管理)来支持CIoT的数据传输。为了简化接口间的信令，可将图1中的MME、S-GW和P-GW的功能都集成在CIoT核心网(CN，Core  Network)的一个网元中，或者，将MME和S-GW集成在一个网元中，而P-GW单独出来，这样可以有效地支撑漫游场景。For the particularity of the CIoT terminal, the CIoT terminal can access the network architecture shown in Figure 2. As shown in FIG. 2, a mobile Internet of Things terminal (CIoT UE) is an Internet of Things terminal that frequently or infrequently transmits small data packets; a mobile Internet of Things Radio Access Network (CIoT RAN) and a mobile Internet of Things Packet Core Network (CIoT EPC) For CIoT's private network, simplified or enhanced EPS-related functions (mobile management and session management) are used to support CIoT data transmission. In order to simplify the signaling between interfaces, the functions of the MME, S-GW and P-GW in FIG. 1 can be integrated into the CIoT core network (CN, Core). In a network element of the Network, the MME and the S-GW are integrated into one network element, and the P-GW is separately provided, so that the roaming scenario can be effectively supported.
为了支持上述功能，相关技术给出一种小数据传输的流程，如图3所示：In order to support the above functions, the related art gives a small data transmission process, as shown in FIG. 3:
步骤300：CIoT UE注册到网络，并与网络建立安全连接；Step 300: The CIoT UE registers with the network and establishes a secure connection with the network.
步骤301：CIoT UE发起随机接入请求，其中携带终端标识以及无连接建立指示；Step 301: The CIoT UE initiates a random access request, where the terminal identifier and the connectionless establishment indication are carried;
步骤302：CIoT RAN返回随机接入响应，其中携带终端标识和上行授权的资源；Step 302: The CIoT RAN returns a random access response, where the terminal identifier and the uplink authorized resource are carried.
步骤303：CIoT UE发送随机接入应答，其中携带上行的小数据，其中，小数据采用加密的NAS传输；Step 303: The CIoT UE sends a random access response, where the small data of the uplink is carried, where the small data is transmitted by using an encrypted NAS.
步骤304：CIoT RAN根据终端标识为CIoT UE选择合适的核心网(如CIoT EPC)，并发送初始UE建立消息，其中携带终端标识和加密的数据；Step 304: The CIoT RAN selects a suitable core network (such as a CIoT EPC) for the CIoT UE according to the terminal identifier, and sends an initial UE setup message, where the terminal identifier and the encrypted data are carried;
步骤305：CIoT EPC校验消息，并且解密数据；CIoT EPC将小数据发送给P-GW，并且临时存储CIoT UE发送小数据的无线接入网标识；Step 305: The CIoT EPC checks the message, and decrypts the data; the CIoT EPC sends the small data to the P-GW, and temporarily stores the radio access network identifier that the CIoT UE sends the small data;
步骤306：当有下行小数据到达，P-GW将其发送给CIoT EPC；Step 306: When there is downlink small data arriving, the P-GW sends it to the CIoT EPC;
步骤307：CIoT EPC根据保存的无线接入网标识，在下行数据到达时进行寻呼优化，CIoT EPC发送寻呼消息给CIoT RAN，其中包含加密的下行数据；Step 307: The CIoT EPC performs paging optimization when the downlink data arrives according to the saved radio access network identifier, and the CIoT EPC sends a paging message to the CIoT RAN, where the encrypted downlink data is included;
步骤308：收到寻呼消息的CIoT RAN寻呼CIoT UE，CIoT UE收到寻呼消息发送应答消息给CIoT RAN，并从CIoT RAN获取加密的下行数据。Step 308: The CIoT RAN that receives the paging message pages the CIoT UE, and the CIoT UE receives the paging message sending response message to the CIoT RAN, and obtains the encrypted downlink data from the CIoT RAN.
虽然移动物联网的大部分业务都是小数据类业务，但是考虑到业务升级或者软件升级等需求，也间或有大数据产生。此时，如果仍然使用图3所示的小数据传输方式，会导致传输速率大大降低。Although most of the services of the mobile Internet of Things are small data services, large data generation may occur depending on the needs of business upgrades or software upgrades. At this time, if the small data transmission method shown in FIG. 3 is still used, the transmission rate is greatly reduced.
