The technical scheme of the embodiment of the invention is mainly applied to a 5G mobile communication system, and is not limited to the 5G mobile communication system, and can 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 (emmbb, enhance Mobile Broadband), low latency high reliability communications (URLLC, ultra Reliable Low Latency Communication), large-scale machine type communications (mctc, massive Machine Type Communication). The following describes a main application scenario in a 5G mobile communication system:

1) ebb scene: the ebb targets users to obtain multimedia content, services and data, and its business needs are growing very rapidly. Since the eMBB may be deployed in different scenarios, such as indoor, urban, rural, etc., the difference between its service capabilities and requirements is also relatively large, so the service must be analyzed in connection with a 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) mctc scenario: typical features of URLLC include: high connection density, small data volume, delay insensitive traffic, low cost and long service life of the module, etc.

In a 5G network environment, for the purposes of reducing air interface signaling and quickly restoring wireless connections, quickly restoring data traffic, a new RRC state, namely an RRC INACTIVE (rrc_inactive) state, is defined. This state is different from the RRC IDLE (rrc_idle) state and the RRC CONNECTED (rrc_connected) state.

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

1) Rrc_idle state: mobility is based on cell selection reselection of the UE, paging is initiated by the CN and paging areas are configured by the CN. The base station side does not have the UE AS context. 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 cell specific. Mobility is network-side controlled mobility. Unicast data may be transmitted between the UE and the base station.

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

When a User Equipment (UE) is in rrc_inactive state, the network side configures the UE with a paging area of a radio access network (RAN, radio Access Network) through dedicated signaling, where the RAN paging area may be one cell or multiple cells. The network side is not notified when the UE moves within the area, and the mobility behavior under idle (idle), i.e. 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 the 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 a RAN and a Core Network (CN) for the UE triggers all cells in the RAN paging area to send paging messages 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, the UE has downlink data to arrive, and the network side initiates paging of the RAN side to prompt the UE to enter a connection state;

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

thirdly, the UE has the requirement of uplink data transmission, so that the UE is promoted 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 resumes RRC connection.

Step 102: the UE sends a preamble (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 resume request message to the gNB (RRC Connection Resume Request).

Step 105: the gNB requests UE context information from the anchor gNB (anchor gNB).

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

Step 107: the UE enters an RRC CONNECTED (rrc_connected) state.

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

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

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

In this embodiment of the present application, the first node is a master node, and the second node is an auxiliary node.

In this 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, a notebook, 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 to enter the inactive state may be: 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 make a decision that the terminal enters an inactive state. For example: the SN may trigger the MN to make a decision for the UE to enter an inactive state through the Xn interface.

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

In this embodiment of the present application, before the first node negotiates with the second node about a first configuration parameter of the terminal in the inactive state, the first node notifies the second node of a TA (Tracking area) 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), and the MN may configure first RAN paging area information of 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 of the SN side based on the TA list. It should be clear that the RAN paging area of the MN or SN side configuration cannot be larger than the range of the TA list.

In this 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, which is sent by the second node; the first node uses 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 parameters.

In the above solution, the first RAN configuration parameter includes at least first RAN paging area information of the first node side, and the second RAN configuration parameter includes at least 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: the MN triggers the SN to negotiate configuration parameters of the UE in the inactive state, where the negotiated configuration parameters at least include RAN paging area information, and further, may also negotiate RAN DRX cycles, periodical RNAU timer. For example, the MN sends a configuration parameter request to the SN, the SN configures RAN configuration parameters and sends them to the MN, and the MN configures the RAN configuration parameters configured by the MN and the SN as a whole to the UE. For the RAN configuration parameters, each RAN minimum configuration carries an indication information, which is used to indicate RAT information corresponding to the area corresponding to the minimum configuration. For example, the RAN is configured as a cell list (cellist), and each configured cell information configures one RAT information indicating whether the cell belongs to NR or LTE. For another example, the RAN is configured as 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, downlink data arrives at the network side, and the network side initiates a RAN paging message to the UE. Specifically, 1) if downlink data reach the first node side, the first node triggers a paging message of RAN initiation, the first node sends the paging message to the terminal in a first RAN paging area configured by the first node, and the first node sends second indication information for indicating that the downlink data reach the first node side to the second node, where the second indication information is used to trigger the second node to send the 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, triggering an RAN initial paging message by the second node, and sending the paging message 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) And if the downlink data arrives at the MN side, the MN triggers the RAN initial paging message and sends the RAN initial paging message to the UE in the RAN area configured by the MN, and meanwhile, the MN sends an indication about the arrival of the DL data to the SN on the Xn interface and triggers the SN to send the RAN initial paging message to the UE in the RAN area configured by the SN. 2) And when downlink data arrives at the SN side, the SN triggers an RAN initial paging message and sends the paging message to the UE in an RAN area configured by the SN, and meanwhile, the SN sends an indication about the arrival of 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.
