In order to facilitate the understanding of the technical solutions of the embodiments of the present application, the technical solutions related to the embodiments of the present application are described below.

As people speed, latency, high-speed mobility, energy efficiency and the future of life in the pursuit of the business of diversity, complexity, for the third Generation Partnership Project ^{(3 rd Generation Partnership Project, 3GPP} ) ISO began the development of 5G . The main application scenarios of 5G are: Enhanced Mobile Broadband (eMBB), Ultra-Reliable Low-Latency Communications (URLLC), Massive Machine-Type Communications (mMTC) ).

On the one hand, eMBB still targets users to obtain multimedia content, services and data, and its demand is growing very rapidly. On the other hand, because eMBB may be deployed in different scenarios, such as indoors, urban areas, rural areas, etc., its capabilities and requirements are also quite different, so it cannot be generalized and must be analyzed in detail in conjunction with specific deployment scenarios. Typical applications of URLLC include: industrial automation, power automation, telemedicine operations (surgery), traffic safety protection, etc. Typical features of mMTC include: high connection density, small data volume, delay-insensitive services, low-cost modules and long service life.

RRC status

5G defines a new RRC state, that is, the RRC_INACTIVE state, for the purpose of reducing air interface signaling, quickly restoring wireless connections, and quickly restoring data services. This state is different from the RRC idle (RRC_IDLE) state and the RRC active (RRC_ACTIVE) state. in,

1) RRC_IDLE state (abbreviated as idle state): mobility is cell selection and reselection based on terminal equipment, paging is initiated by the Core Network (CN), and the paging area is configured by the CN. There is no terminal device context on the base station side, and no RRC connection.

2) RRC_CONNECTED state (referred to as connected state for short): there is an RRC connection, and there is a terminal device context on the base station side and the terminal device side. The network side knows that the location of the terminal equipment is of a specific cell level. Mobility is the mobility controlled by the network side. Unicast data can be transmitted between the terminal equipment and the base station.

3) RRC_INACTIVE state (abbreviated as inactive state): mobility is cell selection reselection based on terminal equipment, there is a connection between CN-NR, the context of terminal equipment exists on a certain base station, and paging is triggered by RAN The RAN-based paging area is managed by the RAN, and the network side knows that the location of the terminal equipment is based on the RAN paging area level.

The above three RRC states can be converted mutually. The terminal device is in the inactive state, and the terminal device autonomously returns to the idle state in the following situations:

When the terminal device receives the CN initial paging message;

When the terminal device initiates an RRC recovery request, it starts timer T319, if the timer expires;

When the terminal equipment fails to verify the integrity of MSG4;

When the terminal device cell is reselected to another radio access technology (Radio Access Technology, RAT);

The terminal device enters the camp on any cell state.

When the terminal device is in the inactive state, the network side will configure the RRC inactive configuration parameters for the terminal device through the RRC release message. The RRC inactive configuration parameters mainly include:

Inactive RNTI (I-RNTI) is used to identify the terminal device inactive context (UE inactive context) of the terminal device on the base station side, and is unique in the base station.

The RAN Notification Area (RNA) is used to control the area where the terminal device performs cell selection and reselection in the inactive state, and is also the paging range area for the initial paging of the RAN.

The RAN paging cycle (RAN Paging cycle) is used to calculate the paging occasion of the RAN initial paging.

The RNA update cycle (RNAU periodicity) is used to control the cycle for the terminal device to perform periodic RAN location update.

The Next Hop Chaining Counter (NCC) is used to determine the secret key used in the RRC connection recovery process.

When the terminal device moves in the RNA area, it does not need to notify the network side, and follows the mobility behavior in the idle state, that is, the principle of cell selection and reselection. When the terminal device moves out of the paging area configured by the RAN, the terminal device triggers a resume RRC connection procedure (that is, RRC resume procedure), and re-acquires the paging area configured by the RAN. When the network side needs to transmit data to the terminal device, that is, when downlink data arrives, the base station that saves the context of the terminal device (that is, the base station that the terminal device maintains the connection between the access network and the core network) will trigger the RAN paging area All the cells in the cell send paging messages to the terminal equipment, so that the terminal equipment in the inactive state can restore the RRC connection and receive data. In addition, the terminal equipment in the inactive state is configured with a RAN paging area. In this area, in order to ensure the reachability of the terminal equipment, the terminal equipment needs to perform periodic location updates according to the network configuration cycle. The scenarios that trigger the terminal device to perform RNA update include the RNAU timer timeout or the terminal device moving to an area outside of RNA. Currently, the inactive state defined by NR does not support terminal equipment to transmit user plane data.

When the target base station where the terminal device initiates the RRC connection recovery process is not an anchor base station, the anchor base station decides whether it is necessary to transfer the context of the terminal device to the target base station side. Generally, the target base station sends the cause value carried in the RRC recovery request message sent by the terminal device to the anchor base station during the terminal context request process, and the anchor base station determines whether the context of the terminal device needs to be transferred to the target base station side. For example, the RRC connection recovery process triggered by the periodic RAN location update generally does not require context transfer.

Through the RRC connection restoration process, the terminal device can transmit small data through the user plane, that is, early data transmission (Early Data Transmission, EDT) or called small data transmission. Specifically, small data is transmitted in a dedicated transmission channel (Dedicated Transmission Channel, DTCH), MSG3 (that is, an RRC recovery request message) is transmitted in a common control channel (CCCH), and DTCH and CCCH are multiplexed and transmitted in the MAC layer. , So as to realize the uplink transmission of small data. In the same way for the downlink, small data is transmitted in DTCH, MSG4 (that is, RRC release message) is transmitted in CCCH, and DTCH and CCCH are multiplexed and transmitted in the MAC layer, thereby realizing the downlink transmission of small data.

It should be noted that the description of “small data” in the embodiment of the present application can also be replaced with “small data packet” or “small data packet”.

Although small packet data transmission is supported in LTE, small packet data transmission in LTE is used in specific scenarios, such as IoT type terminals, that is, the services supported by terminals that perform small packet data transmission are limited to IoT type services, and such terminals themselves The volume of business data is small and supports small packet data transmission. However, in NR, small packet data transmission may have a wider application, so the service supported by the terminal that performs small packet data transmission is no longer a single IoT type service. In order to perform small packet data transmission more effectively, an effective control of small packets is required. Data transmission strategy. To this end, the following technical solutions of the embodiments of the present application are proposed.
