[0138] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present disclosure.

[0139] The AIoT system is officially established in R19, including two main scenarios. Referring to FIG. 1, which is an interaction flowchart of a first scenario of AIoT system application provided by an embodiment of the present disclosure, as shown in FIG. 1, the first scenario is that the devices and base stations in the wireless access network of the AIoT system are connected through the AIoT air interface, that is, the devices in the wireless access network are communicated with the core network through the base station. Referring to FIG. 2, which is an interaction flowchart of a second scenario of AIoT system application provided by an embodiment of the present disclosure. In the second scenario, the devices and terminals (User Equipment, UE) in the wireless access network of the AIoT system are connected through the air interface, and the data is forwarded from the terminal to the base station. For the base station in the first scenario and the terminal in the second scenario, they can be regarded as readers.

[0140] It should be noted that in the embodiments of the present disclosure, AIoT is equivalent to AIOT or A-IoT.

[0141] Currently, the AIoT system communication supports the inventory message and the command message process. For Inventory and command, both are messages from the core network.

[0142] Based on the scope of R19, the devices of the AIoT system have no radio resource control (Radio Resource Control, RRC) state, lack of management scheme of RRC connection state, and cannot perform AIoT device context management.

[0143] To solve the above technical problems, the embodiment of the present disclosure provides an AIoT device context management method, which is applied to a core network. Referring to FIG. 3, it is a flowchart of an AIoT device context management method provided by the embodiment of the present disclosure. The method comprises the following steps:

[0144] In step S1, a device context change request is sent to a radio access network.

[0145] In step S2, a response fed back after the radio access network context is changed is received, and the device context information is updated.

[0146] In the implementation of the embodiment, the method is executed by the core network, the device information is stored in the core network, and the core network pre-stores the device context information uploaded by the radio access network, that is, the core network manages the association relationship of the device in the radio access network, and the association relationship is the communication transmission path of the device.

[0147] When the core network needs to perform communication management, the communication demand triggers a device context change request, and the device context change request is sent to the radio access network according to the device context information.

[0148] After the radio access network receives the device context change request, the corresponding RRC connection is changed, which specifically includes the establishment, update and deletion of the relationship between the device and the saved core network.

[0149] After the RRC connection relationship is changed, the radio access network feeds back the changed device context information to the core network, and the core network updates the device context information according to the received response.

[0150] It should be noted that the embodiment of the present disclosure can be applied to the context management in the above two different scenarios. The construction, change and processing process of the RRC connection in the radio access network are based on the different change control of the communication in the above first and second scenarios.

[0151] The embodiment of the present disclosure manages the device context information of the association relationship between the core network and the radio access network, and sends the uplink change request according to the device context information to perform the RRC connection management, which is applicable to the above two communication scenarios and realizes the management of the association relationship of the radio access network.

[0152] When the RRC connection is constructed, in the first scenario, the RRC connection between the core network and the radio access network is specifically that the core network forwards messages through the base station of the radio access network to construct the RRC connection with the device.

[0153] In the second scenario, the RRC connection between the core network and the radio access network is specifically one of the following two ways:

[0154] The first mode: the core network directly sends a configuration message to the terminal, the terminal sends a message to the device, and RRC access is completed.

[0155] The second mode: the core network sends a message to the base station, the base station sends an air interface configuration message to the terminal, the terminal sends a message to the device, and RRC access is completed.

[0156] The core network directly sends a Non-Access Stratum (NAS) message to the terminal to build an RRC connection with the wireless access network. Referring to FIG. 4, which is a flowchart of an RRC connection building process of the core network and the wireless access network in the second scenario according to an embodiment of the present disclosure, corresponding to the above-mentioned mode one.

[0157] The RRC connection building process of the core network and the device includes the following steps:

[0158] Step 1: The core network carries at least an inventory message to the terminal through an NAS message.

[0159] Step 2: The base station sends an RRC reconfiguration message to the terminal, which contains information configured for AIoT transmission.

[0160] Step 2 can be sent before Step 1.

[0161] Step 3: The terminal sends an inventory message to the device of the wireless access network.

[0162] Step 4: The device initiates a random access procedure to complete random access to the terminal.

[0163] Step 5: The terminal sends information to the core network through an NAS message, which contains one or more AIoT device identifiers (IDs).

[0164] Step 6: The core network carries an instruction message command to the terminal through an NAS message.

[0165] Step 7: The terminal sends the instruction message command to the device.

[0166] Step 8: The device sends a feedback message of the instruction message command to the terminal, which contains an acknowledgement message or other feedback messages, such as read device information.

[0167] Step 9: The terminal receives the instruction feedback message and sends the instruction feedback message to the core network.

[0168] The core network sends a message to the base station, and the base station sends an air interface configuration message to the terminal. In another embodiment provided in the disclosure, referring to FIG. 5, which is a flowchart of another RRC connection construction process of the core network and the radio access network in the second scenario according to an embodiment of the disclosure, corresponding to the above-mentioned mode two.

[0169] The core network sends a message to the base station, and the base station sends an air interface configuration message to the terminal. In another embodiment provided in the disclosure, referring to FIG. 5, which is a flowchart of another RRC connection construction process of the core network and the radio access network in the second scenario according to an embodiment of the disclosure, corresponding to the above-mentioned mode two.

[0170] The specific process includes:

[0171] Step 1: The core network sends a message to the base station, at least carrying an inventory message.

[0172] Step 2: The base station sends an RRC reconfiguration message to the terminal, which contains configuration information for AIoT transmission.

[0174] Step 3: The base station generates and sends an inventory message to the device through the terminal.

[0175] Step 4: The device initiates a random access process and completes random access to the base station.

[0177] Step 6: The core network sends a command message to the base station.

[0178] Step 7: The base station sends a command message to the device.

[0179] Step 8: The AIoT device sends a command feedback message to the base station, including an acknowledgement message or other feedback messages such as read device information.

[0180] Step 9: The base station sends a command feedback message to the core network.

[0181] In addition, the core network sends a message to the base station, and the base station sends an air interface configuration message to the terminal. In another embodiment provided in the disclosure, referring to FIG. 6, which is a flowchart of another RRC connection construction process of the core network and the radio access network in the second scenario according to an embodiment of the disclosure, corresponding to another scheme under the above-mentioned mode two.

[0182] Step 1: The core network sends a message to the base station, at least carrying an inventory message.

[0183] Step2: The base station sends an RRC reconfiguration message to the terminal, which contains information configured for AIoT transmission.

[0184] Wherein Step2 can be sent before Step1.

[0190] Step8: The core network sends a command message to the base station.

[0191] Step9: The base station sends a command message to the terminal.

[0192] Step10: The terminal sends a command message to the device.

[0194] Step12: The terminal sends a command feedback message to the base station, including an acknowledgement message or other feedback messages such as read device information.

[0195] Step13: The base station sends a command feedback message to the core network, including an acknowledgement message or other feedback messages such as read device information.

[0196] That is, the core network sends a message to the base station, the base station sends a message to the terminal, and the terminal sends a message to the device to complete RRC connection, and then feedback messages are constructed according to the connection.

[0197] It should be noted that the above embodiments disclose the specific implementation of the RRC connection process between the core network and the radio access network, i.e., the device access process according to the inventory message or the command message. In the specific context change management, the core network uses any of the above three embodiments to realize the RRC connection change of the context in the second scenario, which is not described here.

[0198] In yet another embodiment provided by the present disclosure, the device context information is stored in the core network, such as device identification, device capability, and association relationship of the device; wherein the association relationship refers to which base station (service gNB) the device is in the coverage of, or which base station (old gNB) the device was in the coverage of last time.

[0199] It should be noted that the association relationship includes which base station the device is in the coverage of, and based on the foregoing several different RRC connection construction schemes of the core network and the wireless access network, the core network establishes connection with the device, which needs to correspond to different association relationships.

[0200] It should be noted that the foregoing process of the core network and the wireless access network constructing the RRC connection can determine specific schemes based on different application scenarios, i.e., specific access modes within the wireless access network.

[0201] After the wireless access network constructs the RRC connection, the device context information is fed back to the wireless access network according to the RRC connection constructed in the wireless access network.

[0202] It should be noted that when the device context information is fed back, the terminal connected with the device feeds back the association relationship between the terminal and the device, and the superior terminal records and feeds back the association relationship in turn, so as to finally form the device context information and feed back to the core network.

[0203] The core network records the device context information fed back by the device based on the RRC connection, stores the initialized device context information, and manages the device context information according to the stored device context information when the RRC connection is changed subsequently.

[0204] The core network performs the initialization configuration process to enable the wireless access network to complete the RRC connection construction, feed back the device context information in the RRC construction process, and complete the storage of the device context information.

[0205] In yet another embodiment provided by the present disclosure, the association relationship of the device includes at least one of the following:

[0206] The association relationship between the device and the base station;

[0207] The association relationship between the device and the terminal;

[0208] The association relationship between the device and the base station, and the association relationship between the base station and the terminal.

[0209] When establishing an RRC connection between the core network and the radio access network, the access of the device may require the participation of the terminal and / or the base station. Therefore, there is also a corresponding association between the base station and the terminal. However, this association may be managed by the base station, and the core network can communicate with the base station corresponding to the device. But when the core network communicates directly with the terminal, the core network needs to determine the association of the terminal corresponding to the device association. The core network sends messages to the radio access network according to the association between the device and the base station / terminal.

[0210] In another embodiment provided in this disclosure, the association between the device and the base station includes the device performing an inventory process or receiving a read / write instruction from the base station when the base station is acting as a reader / writer.

[0211] In scenarios where devices are directly connected to the core network via base stations, the core network needs to determine the association between the devices to be connected and the base stations. Specifically, when obtaining the association between the devices and the base stations, the core network needs to determine the association between the devices and the base stations by either performing an inventory process when the base station is acting as a reader or by receiving read / write instructions from the reader.

[0212] The relationship between the device and the terminal includes whether the device has performed an inventory process when the terminal is used as a reader / writer, or whether it has received read / write instructions from the reader / writer.

[0213] When a device needs to connect through a terminal (which acts as an intermediate terminal), the core network needs to obtain the association relationship between the device and the terminal. Specifically, when obtaining the association relationship between the device and the terminal, the device has performed an inventory process when the terminal acts as a reader or writer, or has received read / write instructions from the reader or writer to determine the association relationship between the device and the terminal.

[0214] In yet another embodiment provided in this disclosure, the association between the device and the base station further includes:

[0215] When a base station or terminal acts as a reader / writer, after performing an inventory or read / write instruction process, it does not perform an inventory or receive any read / write instructions on the device.

[0216] In the association between the device and the base station, there is an association process when the terminal acts as a reader / writer. When the association between the device and the base station is obtained, if the base station or the terminal acts as a reader / writer and has performed an inventory or read / write instruction process, it has not performed an inventory or received a read / write instruction from the device.

[0217] The corresponding relationships are determined by reading the instruction flow or inventory flow transmitted during communication by the base station or terminal acting as a reader / writer.

[0218] In another embodiment provided in this disclosure, the device context change request issued by the core network to the radio access network includes one of the following:

[0219] Context release request;

[0220] Context modification request;

[0221] Context retrieval request.

[0222] The purpose of the device context release procedure is to enable the core network to order the release of the logical NG connection related to the device for various reasons.

[0223] The core network sends a device context release command to the radio access network (e.g., NG-RAN), and the NG-RAN feeds back a device context release completion to the core network. The context release command needs to contain the identity of the device or the NG interface identity of the device.

[0224] The core network can initiate a device context modification procedure. The purpose of the device context modification procedure is to modify an already established device context.

[0225] Specifically, the LMF sends a device context modification request to the radio access network (e.g., NG-RAN), and the NG-RAN feeds back a device context modification response to the LMF. The context release command needs to contain the identity of the device or the NG interface identity of the device.

[0226] The core network sends a context retrieval request to enable the device context retrieval between two NG-RAN nodes. The device context retrieval is used for a new NG-RAN node to retrieve the device context from an old NG-RAN node.

[0227] By issuing different device context change requests to the radio access network, the radio access network performs context change processing according to the received requests. It should be noted that the radio access network context change processing can be performed according to the RRC establishment procedure and the existing RRC connection change procedure, which will not be described here.

[0228] In yet another embodiment provided by the present disclosure, the method further includes:

[0229] The purpose of the device context release procedure is to enable the core network to order the release of the logical NG connection related to the device for various reasons.

[0230] Therefore, the core network needs to perform release trigger monitoring when issuing a context release. The release trigger monitoring monitors whether the inventory or instructions between the device and the core network are completed and whether the device initiates the establishment of a new logical NG connection.

[0231] When the inventory message or instruction message sent to the device in the radio access network is executed, or the device in the radio access network initiates to establish a new RRC connection, a context release command is triggered, and a context release request is sent to the radio access network.

[0232] In yet another embodiment provided by the present disclosure, when the core network sends a device context change request to the radio access network according to device context information, the following process is specifically performed:

[0233] According to the device context information, a corresponding device context change request is determined, that is, according to the association relationship of the device context information, a device that needs to perform RRC connection change and a corresponding base station / terminal are determined, and a device context change request is generated.

[0234] The device context change request is sent to the radio access network by a location management function (LMF) of the core network.

[0235] The device context change request needs to include the identification of the device or the NG interface identification of the device, so that the corresponding device performs NG interface change release.

[0236] In yet another embodiment provided by the present disclosure, the process of sending a device context change request to the radio access network by the core network specifically includes:

[0237] The core network sends a NAS message including a device context change request to a base station, and the base station is specifically a base station associated with the device according to the device context information, that is, a base station covering the location of the device. This method is suitable for a scenario where the device is directly connected to the core network through the base station. In addition, the device is connected to the base station through the terminal, and is connected to the core network through the base station.

[0238] In another scenario, the core network sends a NAS message including the device context change request to a terminal associated with the device in the radio access network. This method is suitable for a scenario where the device is directly connected to the core network through the terminal.

[0239] In yet another embodiment provided by the present disclosure, when the core network sends a device context change request, the following steps are specifically performed:

[0240] According to the device context information, the latest inventory path is determined, and the device context change request is sent according to the inventory path.

[0241] The inventory and the instruction are connected between the core network and the device through the terminal. The inventory path includes a process of the core network to the base station, the terminal, and the device. The base station only needs to configure the terminal to assist in completing the transmission. From the perspective of the core network, the device and the terminal have a correlation. Therefore, the core network issues a device context change request to the corresponding base station.

[0242] Another possible way is that the context of the device is nested in the terminal, that is, the inventory path includes the core network to the terminal and then to the device. That is, the context of the terminal can contain AIoT authorization information; a device information list indicating devices that have been inventoried or commanded by the terminal, the latest device that has been inventoried or commanded, or the device that already has a corresponding relationship. The information list contains device identification, device group identification, device capability, etc.; all devices that have been inventoried or commanded by the terminal indicate that all devices have been inventoried or commanded; the latest device that has been inventoried or commanded indicates the last time that the terminal has been inventoried or commanded.

[0243] When a failure response of the feedback is received, the inventory path is updated according to the device context information, and the device context change request is reissued according to the inventory path.

[0244] For example: the context of terminal 1 inventories the device identification of device 001, 003, and 007; the latest inventory is 001, 003. The context of terminal 2 inventories the device identification of device 002, 003, and 009, and the latest inventory is 002; the core network initiates a read instruction for 002 and 003, and the core network sends the 002 read instruction to terminal 2 and the 003 read instruction to terminal 1; if the feedback of the 003 read instruction to terminal 1 fails, the 003 read instruction can be sent to terminal 2.

[0245] Through the feedback monitoring of the request issued according to the inventory path, the context can be automatically recovered.

[0246] In yet another embodiment provided in the disclosure, the inventory path includes one of the following:

[0247] The terminal that inventories the latest device;

[0248] The base station that inventories the latest device.

[0249] In the implementation of the embodiment, refer to the description of the previous embodiment, and the association relationship between the device, the base station, the terminal, and the core network is based on different scenarios.

[0250] The inventory and the instruction are connected between the core network and the device through the terminal. The base station only needs to configure the terminal to assist in completing the transmission. From the perspective of the core network, the device and the terminal have a correlation, that is, the inventory path includes the terminal that inventories the latest device.

[0251] The possible way is that the context of the device is nested in the terminal, and the inventory path includes the terminal of the latest inventory device.

[0252] In yet another embodiment of the present disclosure, an AIoT device context management method is provided, which is applied to a core network. Referring to FIG. 7, which is another flowchart of the AIoT device context management method provided by another embodiment of the present disclosure, the method comprises the following steps:

[0253] In step S701, an initialization configuration request is sent to a radio access network.

[0254] In step S702, an initialization response fed back by the radio access network is received, and device context information in the initialization response is stored.

[0255] The process of pre-storing device context information by the core network is the process of feeding back device context information after the radio access network is constructed based on the RRC connection. Specifically, the process comprises the following steps:

[0256] The initialization configuration request is sent to the radio access network by the core network.

[0257] In the initial state, the device in the radio access network does not construct an RRC connection with the intermediate terminal or the base station. The radio access network constructs the RRC connection according to the received initialization configuration request, that is, constructs the communication connection between the device and the intermediate terminal or the base station, and then realizes the connection with the core network through the base station or the intermediate terminal.

[0258] Through the management of the device context information, the association relationship between the device in the RRC connection and the base station / terminal in the radio access network is managed.

[0259] It should be noted that the AIoT device context management method provided in the present embodiment can perform all steps of the AIoT device context management method applied to the core network in any of the above embodiments after the initialization configuration, and thus will not be described here.

[0260] In yet another embodiment of the present disclosure, an AIoT device context management method is provided, which is applied to a radio access network. Referring to FIG. 8, which is another flowchart of the AIoT device context management method provided by the present embodiment. The method comprises the following steps:

[0261] In step S801, a device context change request sent by the core network is received.

[0262] In step S802, the RRC connection is changed according to the device context change request, and the changed device context information is fed back to the core network.

[0263] In the specific implementation of the present embodiment, the method is executed by the radio access network, and the following steps are executed:

[0264] receiving a device context change request issued by the core network; wherein the device context change request comprises an association relationship of the RRC connection to be changed.

[0265] The radio access network performs RRC connection change according to the received device context change request.

[0266] It should be noted that the RRC connection construction process between the radio access network and the core network refers to the communication process provided in FIGS. 4-6 under several different scenarios. When the RRC is changed, the corresponding communication process is used to change the RRC connection, and the changed device context information is fed back to the core network.

[0267] The radio access network performs RRC connection according to the device context change request issued by the core network, feeds back the corresponding device context information to the core network based on the changed access relationship of the radio access network, and completes the management of the association relationship and the change process.

[0268] In yet another embodiment provided by the present disclosure, the device context information is stored in the core network, such as device identifier, device capability, and device association relationship. The association relationship refers to the device coverage range of which base station (service gNB) or the last base station (old GNB).

[0269] It should be noted that the association relationship includes the device coverage range of which base station, and based on the foregoing several different RRC connection construction schemes of the core network and the radio access network, the core network and the device establish connection, which needs to correspond to different association relationships.

[0270] It should be noted that the process of establishing RRC connection between the core network and the radio access network can determine specific schemes based on different application scenarios, i.e. the specific access mode in the radio access network.

[0271] After the radio access network establishes the RRC connection, the device context information is fed back to the radio access network according to the RRC connection established in the radio access network.

[0272] It should be noted that when the device context information is fed back, the device terminal connected with the device feeds back its association relationship with the device, and the upper terminal device records and feeds back the association relationship in turn, and finally forms the device context information, which is fed back to the core network.

[0273] The core network records the device context information fed back by the device based on the RRC connection, stores the initialized device context information, and manages the RRC connection change in the subsequent process according to the stored device context information.

[0274] The core network feeds back device context information in the RRC connection establishment process by an initialization configuration process, and stores the device context information.

[0275] In another embodiment provided by the present disclosure, the association relationship between the device and the base station includes that the device has performed an inventory process or received a read / write instruction from the base station as a reader / writer.

[0276] That is, in the scenario that the device is directly connected to the core network through the base station, the core network needs to determine the association relationship between the device and the base station. Specifically, the association relationship between the device and the base station is determined when the base station as a reader / writer has performed an inventory process or received a read / write instruction from the base station.

[0277] The association relationship between the device and the terminal includes that the device has performed an inventory process or received a read / write instruction from the terminal as a reader / writer.

[0278] When the device needs to be connected through the terminal as an intermediate terminal, the core network needs to obtain the association relationship between the device and the terminal. Specifically, the association relationship between the device and the terminal is determined when the terminal as a reader / writer has performed an inventory process or received a read / write instruction from the terminal.

[0279] In another embodiment provided by the present disclosure, the association relationship between the device and the base station further includes:

[0280] The base station or the terminal as a reader / writer has not performed an inventory process or received a read / write instruction after the inventory process or the read / write instruction process.

[0281] In the association relationship between the device and the base station, there is an association process when the terminal as a reader / writer. When the association relationship between the device and the base station is obtained, the base station or the terminal as a reader / writer has not performed an inventory process or received a read / write instruction after the inventory process or the read / write instruction process.

[0282] The corresponding association relationship is determined by reading the instruction process or the inventory process transmitted during communication through the base station or the terminal as a reader / writer.

[0283] In another embodiment provided by the present disclosure, the association relationship includes at least one of:

[0284] The association relationship between the device and the base station;

[0285] The association relationship between the device and the terminal;

[0286] The association relationship between the device and the terminal, and the association relationship between the terminal and the base station.

[0287] When the core network and the radio access network establish the RRC connection, the access of the device can need the participation of the terminal and / or the base station, so there is also a corresponding association relationship between the base station and the terminal, but this association relationship can be managed by the base station, and the core network communicates with the corresponding base station of the device, but when the core network directly communicates with the terminal, the core network needs to determine the association relationship of the terminal corresponding to the association relationship of the device, and the core network sends a message to the radio access network according to the association relationship of the device and the base station / terminal.

[0288] In yet another embodiment provided by the present disclosure, the method further comprises:

[0289] When the device in the radio access network receives the inventory message or the instruction message of the new terminal, the association relationship with the original terminal is deleted, the association relationship with the terminal is saved, the device context information is updated, and the updated context information is fed back to the connected terminal, and the terminal feeds back the updated device context information to the core network; or,

[0290] When the device in the radio access network receives the inventory message or the instruction message of the new terminal, the association relationship with the new terminal is saved, the device context information is updated, and the updated context information is fed back to the connected terminal, and the terminal feeds back the updated device context information to the core network.

[0291] In yet another embodiment provided by the present disclosure, when the radio access network specifically changes the RRC connection, the changing process includes one of the following based on different scenarios:

[0292] When the RRC connection in the radio access network is composed of the core network, the base station and the device, the device context change request is received by the base station in the radio access network, and the device context change request is forwarded to the target device.

[0293] When the RRC connection in the radio access network is composed of the core network, the terminal and the device, the device context change request is received by the terminal in the radio access network, and the device context change request is forwarded to the target device.

[0294] When the RRC connection in the radio access network is composed of the core network, the base station, the terminal and the device, the device context change request is received by the base station in the radio access network, and the device context change request is sent to the terminal, and the terminal forwards the device context change request to the target device.

[0295] Based on different RRC connection modes in different scenarios, when the radio access network performs the RRC connection, different message forwarding mechanisms are used to control the RRC connection mode and perform the context change.

[0296] Another embodiment of the present disclosure also provides an AIoT device context management method, applied to a wireless access network. Referring to FIG. 9, which is another flowchart of the AIoT device context management method provided by the embodiment of the present disclosure, the method comprises the following steps:

[0297] In step S901, an initial configuration request issued by a core network is received.

[0298] In step S902, an RRC connection is established according to the initial configuration request, and device context information of the RRC connection is fed back to the core network.

[0299] After the wireless access network establishes the RRC connection, the device context information is fed back to the core network, so that the core network pre-stores the device context information, which specifically comprises the following steps:

[0300] The initial configuration request issued by the core network is received.

[0301] In the initial state, no RRC connection is established between the device in the wireless access network and the terminal or the base station. The wireless access network establishes the RRC connection according to the received initial configuration request, that is, the communication connection between the device and the terminal or the base station is established, and then the connection with the core network is realized through the terminal or the base station.

[0302] In the first scenario, the RRC connection between the core network and the wireless access network is that the core network forwards a message through the base station of the wireless access network to establish the RRC connection with the device.

[0303] In the second scenario, the RRC connection between the core network and the wireless access network is any one of the following two modes:

[0304] The first mode is that the core network directly sends a configuration message to the terminal, the terminal sends a message to the device, and the RRC access is completed.

[0305] The second mode is that the core network sends a message to the base station, the base station sends an air interface configuration message to the terminal, and the terminal sends a message to the device, and the RRC access is completed.

[0306] It should be noted that the process of establishing the RRC connection by the device in different scenarios and different modes is described in the connection establishment process described above, which will not be repeated here.

[0307] The wireless access network establishes the RRC connection based on the initial configuration information issued by the core network, and feeds back the device information to the core network based on the RRC connection.
