The technical solution of the embodiment of the present invention is mainly applied to a 5G mobile communication system. Of course, the technical solution of the embodiment of the present invention is not limited to the 5G mobile communication system, and can also be applied to other types of mobile communication systems. The main application scenarios of 5G mobile communication technology are: enhanced mobile broadband (eMBB, Enhance Mobile Broadband), low-latency high-reliability communication (URLLC, Ultra Reliable Low Latency Communication), large-scale machine communication (mMTC, Mass Machine Type Communication) ). The following describes the main application scenarios in 5G mobile communication systems:

1) eMBB scenario: eMBB targets users to obtain multimedia content, services, and data, and its business demand is growing rapidly. Because eMBB may be deployed in different scenarios, such as indoor, urban, rural, etc., and its service capabilities and requirements vary widely, it is necessary to analyze services in conjunction with specific deployment scenarios.

2) URLLC scenario: Typical applications of URLLC include: industrial automation, electric power automation, telemedicine operations, and traffic safety assurance.

3) mMTC scenario: The typical characteristics of URLLC include: high connection density, small amount of data, delay-insensitive services, low cost of modules, and long service life.

In the 5G network environment, in order to reduce air interface signaling, quickly restore wireless connections, and quickly restore data services, a new RRC state is defined, that is, an RRC_INACTIVE state. This state is different from the RRC idle (RRC_IDLE) state and the RRC connected (RRC_CONNECTED) state.

The following describes the three RRC states in a 5G network environment:

1) RRC_IDLE state: mobility is UE-based cell selection reselection, paging is initiated by the CN, and paging area is configured by the CN. There is no UE AS context on the base station side. There is no RRC connection.

2) RRC_CONNECTED state: There is an RRC connection, and there is a UE AS context between the base station and the UE. The network knows that the location of the UE is at a specific cell level. Mobility is the mobility controlled by the network side. Unicast data can be transmitted between the UE and the base station.

3) RRC_INACTIVE state: Mobility is UE-based cell selection reselection, there is a connection between CN and RAN, the UE AS context exists on a certain base station, paging is triggered by RAN, and RAN-based paging area is managed by RAN. The network knows that the location of the UE is based on the paging area level of the RAN.

When the user equipment (UE, User Equipment) is in the RRC_INACTIVE state, the network side configures the UE with a radio access network (RAN, Radio Access Network) paging area through dedicated signaling. The RAN paging area can be a cell or Multiple communities. When the UE moves in the area, it does not need to notify the network side, and follows the mobility behavior under idle, that is, the cell selection reselection principle. When the UE moves out of the paging area configured by the RAN, the UE will be triggered to resume the RRC connection and reacquire the paging area configured by the RAN. When the UE has downlink data arriving, the base station (such as gNB) that maintains the connection between the RAN and the Core Network (CN) for the UE will trigger all cells in the RAN paging area to send paging messages to the UE, making the INACTIVCE state UE can recover RRC connection and receive data.

Therefore, the UE enters the RRC connection state from the INACTIVE state. There are three cases:

First, when the UE has downlink data arriving, the network side initiates a paging on the RAN side, prompting the UE to enter the connected state;

Second, the UE initiates RAN location area update itself, such as periodic RAN location update or cross-region location update;

The third is that the UE has an uplink data sending demand, which prompts the UE to enter a connected state.

Figure 2 is a schematic diagram of the RRC connection recovery process. As shown in Figure 2, the RRC connection recovery process includes the following processes:

Step 101: The UE is in the INACTIVE state, and the RRC connection needs to be restored.

Step 102: The UE sends a preamble to the gNB.

Step 103: The gNB sends a Random Access Response (RAR, Random Access Response) to the UE.

Step 104: The UE sends an RRC recovery request message (RRC Connection Resume Request) to the gNB.

Step 105: The gNB asks the anchor gNB (anchor gNB) for UE context information.

Step 106: The gNB sends an RRC Connection Resume message (RRC Connection Resume) to the UE.

Step 107: The UE enters an RRC_CONNECTED state.

Step 108: The UE sends an RRC Connection Recovery Complete message (RRC Connection Resume Complete) to the gNB.

FIG. 3 is a schematic flowchart of an information transmission method according to an embodiment of the present application. As shown in FIG. 3, the information transmission method includes the following steps:

Step 301: The first node sends a first command to the terminal, where the first command is used to instruct the terminal to enter an inactive state.

In the embodiment of the present application, the first node is a primary node, and the second node is a secondary node.

In the embodiment of the present application, the terminal may be any device capable of communicating with a network, such as a mobile phone, a tablet computer, a vehicle-mounted terminal, and a notebook. Further, the terminal is a terminal configured with a DC mode or an MC mode.

In the embodiment of the present application, the network architecture may be a DC network or an MC network. The network side decides to order the UE to enter an inactive state, and the method may be as follows: the first node judges the terminal to enter an inactive state. Further, the first node determines that the terminal enters an inactive state, and sends the first command to the terminal.

In an embodiment, the first node receives a trigger message sent by the second node, and the trigger message is used to trigger the first node to make a decision that the terminal enters an inactive state. For example, the SN can trigger the MN to make a decision for the UE to enter the inactive state through the Xn interface.

Step 302: The first node and a second node negotiate a first configuration parameter of the terminal in the inactive state, and the first node configures the first configuration parameter to the terminal.

In the embodiment of the present application, before the first node and the second node negotiate a first configuration parameter of the terminal in the inactive state, the first node notifies the second node of a tracking area of the terminal. (TA, Tracking Are) list, where the TA list is used by the second node to configure a second radio access network RAN configuration parameter.

Here, the TA list of the terminal is configured to the MN by the core network (CN). The MN can configure the first RAN paging area information on the MN side based on the TA list. The MN needs to send the TA list of the terminal to the SN in order to The SN configures the second RAN paging area information on the SN side based on the TA list. It should be clear that the RAN paging area configured on the MN or SN side cannot be larger than the range of the TA list.

In the embodiment of the present application, the first node triggers the second node to negotiate a first configuration parameter of the terminal in the inactive state. Specifically, the first node sends a configuration parameter request message to the second node, and receives a second RAN configuration parameter configured by the second node and sent by the second node; The first RAN configuration parameter configured by the first node and the second RAN configuration parameter configured by the second node are used as the first configuration parameter.

In the above solution, the first RAN configuration parameter includes at least the first RAN paging area information on the first node side, and the second RAN configuration parameter includes at least the second RAN paging area on the second node side. information. Further, in the first configuration parameter, each unit area in the first RAN paging area information or the second RAN paging area information carries first indication information, and the first indication information is used for Indicates the radio access type RAT information corresponding to the unit area. The RAT information is an NR type or an LTE type.

For example, the MN triggers the SN to negotiate the configuration parameters of the UE in the inactive state. The negotiated configuration parameters include at least RAN paging area information. Further, RAN, DRX cycle, periodic RNAU timer can also be negotiated. For example, the MN sends a configuration parameter request to the SN, the SN configures the RAN configuration parameters, and sends the RAN configuration parameters to the MN, and the MN configures the RAN configuration parameters respectively configured by the MN and the SN to the UE as a whole. As for the RAN configuration parameters, each RAN minimum configuration carries an indication information for indicating the RAT information corresponding to the area corresponding to the minimum configuration. For example, the RAN is configured as a cell list, and each configured cell information is configured with RAT information, and the RAT information indicates whether the cell belongs to NR or LTE. For another example, the RAN is configured as a TA list, and each configured TA information is configured with RAT information, and the RAT information indicates whether the TA belongs to NR or LTE.

In the embodiment of the present application, downlink data reaches the network side, and the network side initiates an RAN paging message to the UE. Specifically, 1) if downlink data reaches the first node side, the first node triggers an initial paging message of the RAN, and the first node is in a first RAN paging area configured by the first node Sending a paging message to the terminal, and the first node sends second instruction information to the second node to indicate that downlink data has reached the first node side, and the second instruction information is used for For triggering the second node to send a paging message to the terminal in a second RAN paging area configured by the second node. 2) If downlink data reaches the second node side, the second node triggers an initial paging message of the RAN, and the second node sends a search request in a second RAN paging area configured by the second node. Call message to the terminal; the first node receives third instruction information sent by the second node to indicate that there is downlink data reaching the second node side; the first node is based on the third instruction Information, sending a paging message to the terminal in a first RAN paging area configured by the first node.

For example: 1) When the downlink data reaches the MN side, the MN triggers the initial paging message of the RAN and sends it to the UE in the RAN area configured by the MN. At the same time, the MN sends an indication to the SN on the Xn interface that the DL data reaches the MN side. , Triggering the SN to issue the RAN initial paging message to the UE in the RAN area configured by the SN. 2) When the downlink data reaches the SN side, the SN triggers the initial paging message of the RAN and sends it to the UE in the RAN area configured by the SN. At the same time, the SN sends an indication to the MN on the Xn interface that the DL data reaches the SN side, triggering the MN to The RAN area configured by the MN sends an initial RAN paging message to the UE.
