The technical solution of the embodiment of the present invention is mainly applied to a 5G mobile communication system, and certainly, 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 the 5G mobile communication technology are as follows: enhanced Mobile Broadband (eMBB), Low-Latency high-reliability Communication (URLLC), and massive Machine Type Communication (mMTC). The following describes the main application scenarios in the 5G mobile communication system:

1) eMB scene: the eMBB targets users to obtain multimedia content, services and data, and its traffic demand is growing very rapidly. Because the eMBB may be deployed in different scenarios, such as indoor, urban, rural, etc., and the difference between the service capability and the requirement is relatively large, the service must be analyzed in combination with the specific deployment scenario.

2) URLLC scene: typical applications of URLLC include: industrial automation, electric power automation, remote medical operation, traffic safety guarantee, and the like.

3) mMTC scenario: typical features of URLLC include: high connection density, small data volume, time delay insensitive service, low cost of the module, long service life and the like.

In a 5G network environment, in order to reduce air interface signaling and quickly recover radio connection and quickly recover data service, a new RRC state, i.e., an RRC INACTIVE (RRC _ INACTIVE) state, is defined. This state is distinguished from an RRC IDLE (RRC _ IDLE) state and an RRC CONNECTED (RRC _ CONNECTED) state.

Three RRC states in a 5G network environment are described below:

1) RRC _ IDLE state: the mobility is the cell selection reselection based on the UE, the paging is initiated by the CN, and the 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 the base station and UE have a UE AS context. The network side knows that the location of the UE is at a specific cell level. Mobility is network side controlled mobility. Unicast data may 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 the CN and the RAN, the UE AS context exists on a certain base station, paging is triggered by the RAN, the RAN-based paging area is managed by the RAN, and the network side knows that the location of the UE is based on the paging area level of the RAN.

When a User Equipment (UE) is in an RRC _ INACTIVE state, a Network side configures a paging area of a Radio Access Network (RAN) to the UE through dedicated signaling, where the RAN paging area may be one cell or multiple cells. When the UE moves in the area, the network side is not informed, and the idle (idle) mobility behavior, namely the cell selection reselection principle, is followed. When the UE moves out of the paging area configured by the RAN, the UE is triggered to recover RRC connection and reacquire the paging area configured by the RAN. When downlink data arrives at the UE, a base station (e.g., a gNB) that maintains a connection between the RAN and a Core Network (CN) for the UE triggers all cells in a RAN paging area to send a paging message to the UE, so that the UE in INACTIVCE state can recover RRC connection and receive data.

So the UE enters the RRC connected state from the INACTIVE state, there are three cases:

firstly, when downlink data arrives at the UE, a network side initiates paging of an RAN side to promote the UE to enter a connection state;

secondly, the UE initiates a RAN location area update, for example, a periodic RAN location update or a cross-area location update;

thirdly, the UE has the requirement of sending uplink data, and the UE is prompted to enter a connection state.

Fig. 2 is a schematic diagram of an RRC connection recovery procedure, and as shown in fig. 2, the RRC connection recovery procedure includes the following procedures:

step 101: the UE is in INACTIVE state and is about to resume RRC connection.

Step 102: the UE transmits a preamble (preamble) to the gNB.

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

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

Step 105: the gbb asks the anchor gbb (anchor gbb) 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 (RRC _ CONNECTED) state.

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

Fig. 3 is a schematic flow chart of an information transmission method provided in an embodiment of the present application, and as shown in fig. 3, the information transmission method includes the following steps:

step 301: the first node sends a first command to a terminal, wherein the first command is used for indicating the terminal to enter an inactive state.

In the embodiment of the present application, the first node is a master node, and the second node is a slave node.

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

In this embodiment of the present application, the network architecture may be a DC network or an MC network, and the network side decision command UE enters an inactive state, which may be implemented by the following manner: and the first node judges that the terminal enters an inactive state. Further, the first node judges 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, where the trigger message is used to trigger the first node to determine that the terminal enters an inactive state. For example: the SN may trigger the MN to make a decision that the UE enters the inactive state through the Xn interface.

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

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

Here, a TA list of the terminal is configured to the MN by a Core Network (CN), the MN may configure first RAN paging area information on the MN side based on the TA list, and the MN needs to send the TA list of the terminal to the SN, so that the SN configures 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 this embodiment, 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 node takes a first RAN configuration parameter configured by the first node and a second RAN configuration parameter configured by the second node as the first configuration parameter.

In the foregoing solution, the first RAN configuration parameter at least includes first RAN paging area information of the first node side, and the second RAN configuration parameter at least includes second RAN paging area information of the second node side. 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, where the first indication information is used to indicate radio access type RAT information corresponding to the unit area. The RAT information is of NR type or LTE type.

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

In the embodiment of the application, the downlink data reaches the network side, and the network side initiates RAN paging information to the UE. Specifically, 1) if downlink data reaches the first node side, the first node triggers a RAN initial paging message, the first node sends a paging message to the terminal in a first RAN paging area configured by the first node, and the first node sends second indication information used for indicating that downlink data reaches the first node side to the second node, where the second indication information is used 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 reach the second node side, the second node triggers RAN initial paging information, and the second node sends the paging information to the terminal in a second RAN paging area configured by the second node; the first node receives third indication information which is sent by the second node and used for indicating that downlink data reach the second node side; and the first node sends a paging message to the terminal in a first RAN paging area configured by the first node based on the third indication information.

For example: 1) when the downlink data reaches the MN side, the MN triggers RAN initial paging information and sends the paging information to the UE in the RAN area configured by the MN, and meanwhile, the MN sends an indication that SN reaches the MN side about the DL data on an Xn interface and triggers the SN to send the RAN initial paging information to the UE in the RAN area configured by the SN. 2) When the downlink data reaches the SN side, the SN triggers the RAN initial paging message and sends the paging message to the UE in the RAN area configured by the SN, and meanwhile, the SN sends an indication about the arrival of the DL data at the SN side to the MN on an Xn interface, and triggers the MN to send the RAN initial paging message to the UE in the RAN area configured by the MN.

In an embodiment, 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, where the first indication information is used to indicate radio access type RAT information corresponding to the unit area
