Technical field

This document relates to, but is not limited to, the field of communications, and in particular, to a communication method, apparatus, and terminal.

Background technique

In order to maintain the competitiveness of the third generation mobile communication (3G) system in the communication field, the 3rd Generation Partnership Project (3GPP) is working on the evolution of the packet domain system (EPS, Evolved Packet System). the study. Figure 1 is a network architecture diagram of EPS. As shown in FIG. 1 , the entire EPS mainly includes an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) and an Evolved Packet Core (EPC). Among them, the EPC can support users from the Global System for Mobile Communication (GSM) Enhanced Data Rate for GSM Evolution (EDGE, GSM EDGE radio access network) and Access to the Universal Terrestrial Radio Access Network (UTRAN).

The evolved packet core network includes: Home Subscriber Server (HSS), Mobility Management Entity (MME), Serving Gateway (S-GW), and Packet Data Network Gateway (P-GW). , PDN Gateway), a General Packet Radio Service (GPRS) Supporting Node (SGSN), and a Policy and Charging Rules Function (PCRF).

The HSS is the permanent storage location of the user subscription data, and is located in the home network that the user subscribes to; the MME is the storage location of the user subscription data in the current network, and is set as the non-access stratum (NAS, Non-Access Stratum) responsible for the terminal to the network. Signaling management, tracking and paging management functions and bearer management in user idle mode; S-GW is a gateway from the core network to the wireless system, and is set to be responsible for user plane bearer of the terminal to the core network and data buffering in the terminal idle mode. , the network side initiates the service request function, the legal eavesdropping and the packet data routing and forwarding function; the P-GW is the evolved packet domain system The gateway of the external network of the system is set to be responsible for the network protocol (IP, Internet Protocol) address allocation, charging function, packet filtering, and policy application of the terminal; the SGSN is the service support for the GERAN and UTRAN users to access the EPC. The function is similar to the MME, and is set to be responsible for the user's location update, paging management, and bearer management functions; the PCRF is configured to provide policy control and control to the Policy and Charging Enforcement Function (PCEF). Billing rules.

Iu is the interface between the radio network controller and the SGSN, Gr is the interface between the SGSN and the HSS, S1-MME is the interface between the base station and the MME, and S1-U is the interface between the base station and the S-GW. S3 is the interface between the MME and the SGSN, S4 is the interface between the SGSN and the S-GW, S5 is the interface between the S-GW and the P-GW, S6a is the interface between the MME and the HSS, and S7 is the P. - The interface between the GW and the PCRF, S10 is the interface between the MME, S11 is the interface between the MME and the S-GW, SGi is the interface between the P-GW and the packet data network, and Rx is the PCRF and the packet data network. The reference point interface between.

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.

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.

In order to support the above functions, the related art gives a small data transmission process, as shown in FIG. 3:

Step 300: The CIoT UE registers with the network and establishes a secure connection with the network.

Step 301: The CIoT UE initiates a random access request, where the terminal identifier and the connectionless establishment indication are carried;

Step 302: The CIoT RAN returns a random access response, where the terminal identifier and the uplink authorized resource are carried.

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.

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;

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;

Step 306: When there is downlink small data arriving, the P-GW sends it to the CIoT EPC;

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;

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.

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.
