The information transmission method, terminal, and network device provided by the embodiments of the present application will be described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.

As shown in Figure 1, at least one embodiment of the present application provides an information transmission method applied to a terminal, including:

Step 101, acquiring binding information between a terminal and at least one device and a mapping relationship between at least one device and a radio bearer RB;

Step 102: Based on the binding information and the mapping relationship, perform information transmission with the first network device, so as to implement unified management of the at least one device.

It should be noted that the first network device is a device on the access network side, for example, may be a base station.

In one embodiment, in at least one embodiment of the present application, the mapping relationship is configured for the terminal by the first network device, that is to say, the first network device must first establish at least one device and RB bound to the terminal. The mapping relationship, and then send the mapping relationship to the terminal, the terminal stores the mapping relationship, and when information interaction is required, information analysis is performed according to the mapping relationship.

In an embodiment, in at least one embodiment of the present application, the binding information is configured for the terminal by the second network device, and the binding information is a correspondence between a terminal identifier and a device identifier.

It should be noted that the second network device is a device on the core network side, for example, a network element of the core network.

Specifically, the second network device acquires binding information through the following steps:

Assign a terminal identifier to the terminal;

Bind the terminal identifier with the device identifier, and acquire binding information between the terminal and at least one device.

It should be noted that, in at least one embodiment of the present application, by establishing the binding information between the terminal and at least one device and the mapping relationship between at least one device and RB, information for different devices can be transmitted at the same time and processed in a unified manner. It can realize the network industry integration of different devices.

It should be noted here that the device mentioned in the embodiment of the present application mainly refers to the user's wearable device.

Firstly, the application scenario of at least one embodiment of the present application will be specifically described as follows.

In the embodiment of the present application, a terminal context solution centered on digital twin user-centric network and industry integration is proposed to meet the demand for possibly more user-centered information processing models in next-generation mobile communications. By definition in the NAS layer (it should be noted that the NAS layer corresponds to the function of the core network on the network side) and the layer (it should be noted that the AS layer corresponds to the function of the access network (for example, a base station) on the network side) The context mode of User Equipment (UE) implements the context scheme with UE as the key retrieval key, and realizes that through the terminal identification (for example, UE ID or UE identity), all equipment measurement information related to the user can be obtained.

For different scenarios, define user-centric contextual solutions. Three scenarios:

Scenario 1. All devices worn by the same user are connected to a terminal (in an embodiment, the terminal refers to the terminal held by the user), and the terminal is connected to the network side through the terminal to establish context information.

Scenario 2: All devices worn by the same user can be independently connected to the network.

Scenario 3, a mix of Scenario 1 and Scenario 2.

It should be noted that the above three scenarios need to have a unified UE context solution. Based on this, the embodiment of this application proposes a protocol function solution for digital twin user-centric network industry integration, mainly as follows:

For wearable Internet of Things devices owned by the user, an index information table centered on the user is established on the network side, and the index information table contains information about all wearable Internet of Things devices bound to the user. as shown in picture 2.

1. User information: the basic context of the user. For example, after the UE accesses the network, it is assigned Cell-Radio Network Temporary Identifier (C-RNTI), Subscription Concealed Identifier (SUCI), and permanent user identifier (Subscription Permanent Identifier, SUPI), Globally Unique Temporary Identifier (GUTI) or other system-defined identity identification as the UE ID of the UE, and then establish a signaling radio bearer (signaling Radio Bearer, SRB) with For signaling transmission, etc. The user at this time may be through the user's handheld terminal, or may be a certain device in the user's wearable Internet of Things device. The ID of the user is recorded as: UEkey ID, which is expressed as the primary ID of the UE.

In addition, it also includes the function information of the user's NAS, such as configuration information of access and mobility management function (Access and Mobility Management Function, AMF), user plane function (User Plane Function, UPF) and other functions.

2. Wearable IoT device identity: For each wearable IoT device, assign an ID, which is recorded as: D1...n ID. This ID is the user's internal ID, which is the subsidiary ID of the UEkey ID. Use D1...n ID as the index to describe the characteristics of each device.

3. Bearer: For each device whose D1...n ID is an index identifier, a dedicated wireless bearer is established.

Figure 2 shows the presentation forms of the device at the application (AP: Application) layer, NAS and AS. The AP layer is mainly presented in the form of digital twins. For example, UE has multiple digital twins, and each twin corresponds to a device; the NAS layer establishes the user's device ID (D ID) to identify each device under the user; The AS layer establishes several radio bearers (IP flow, each device is identified by IP address) for each UE. Each radio bearer corresponds to a device, and when performing air interface transmission, the data on each radio bearer is transmitted according to the quality of service. (Quality of Service, QoS) transmission requirements are mapped to different air interface transmission bearers (identified by QoS flow) and transmitted on the air interface.

Due to the existence of uplink transmission and downlink transmission in information transmission, through the above-mentioned protocol functions, in at least one embodiment of the present application, for downlink transmission, the optional implementation of step 102 is as follows:

The MAC layer receives the first information sent by the first network device, and the first information includes RB identification information and a data packet. It should be noted that the data packet may be a control instruction for the device, for example, a data collection instruction;

The NAS layer sends the data packet to the at least one target device according to the device identifier of the at least one target device.

It should be noted that the downlink data is sent from the network side to the terminal. Usually, the application function (Application function, APF, also called AF) receives the user's data collection instructions for multiple devices, and then sends the instructions through the core network, the interface The network access is transmitted to the terminal, and the terminal parses the command and sends it to the corresponding device, and the device collects corresponding data according to the command.

For uplink transmission, an optional implementation of step 102 is:

The AS layer receives the NAS data packet through a data flow, maps the NAS data packet to a quality of service flow and sends it to the MAC layer, each target device corresponds to a data flow, and each data flow corresponds to a quality of service flow, the The Data Stream includes User Data;

It should be noted that the uplink data is fed back to the network side by the terminal. Specifically, after the terminal receives the data returned by the device, it returns the data to the core network through the access network, and the core network comprehensively analyzes and processes the data. Obtain comprehensive data for users, and finally transmit the data to APF, and APF presents the data.

The uplink transmission and the downlink transmission are described in detail below.

Figure 3 shows the "digital twin user-centered" network industry convergence protocol stack solution. In the entire protocol stack solution, the downlink mainly transmits signaling and control information sent by the network layer, and the uplink mainly transmits signaling and control information sent by the network side. and control, complete the reporting of monitoring information (data).

In downlink transmission, information is sent from the network side to the terminal side, and through user-oriented operations, commands to wearable devices are generated. The downlink direction is described from the APF, the core network, the AS, NAS of the base station and the terminal, and various devices (Dn in FIG. 3, D is the abbreviation of Device, the same below).

The main implementation process of the downlink network side:

For APF, it has an operable user interface (User Interface, UI). In APF, a user's digital twin (Digital Twin Environment, DTE) is established to record the main characteristics of the user and record the user's Characteristics of the wearable device being carried. The user and various devices carried by the user are presented through the operation interface and can be operated.

For the core network (Core Network, CN): able to accept commands (Command) or requests sent by APF. After analyzing the command or request (Analyzing the Command), generate corresponding NAS signaling (Transmitting Signaling) according to the requirements of the command or request.

It should be noted that the context control system based on the user is established in the CN, including the D1...n ID of each device. When the CN sends the NAS signaling for the user's wearable device to the base station, it carries the device's ID D ID.

The CN transmits NAS signaling through the interface with the base station. The TNL layer in Figure 3 is the Transport Network Layer. Based on TNL, a radio network layer (Radio Network Layer, RNL) protocol (such as Stream Control Transmission Protocol (Stream Control Transmission Protocol, SCTP), etc.) can be introduced, or it can not be introduced, and the TNL transmission protocol can be directly used for transmission.

Base Station (base station): After receiving the NAS protocol data unit (Protocol Data Unit, PDU) through the interface with CN, through the carried D ID, obtain the user's bound device identification information, and index to the wireless network that carries the device. Bearer RB.

The Base Station establishes a context information unit with the UE as the unit, and the user's primary ID is the C-RNTI of the UE, or an ID that has nothing to do with the air interface cell where the UE is located (for example, with the base station as the unit, a UE is assigned a unique ID in the base station. ID, the ID does not change with the handover of the UE running on the base station). Based on the UE ID, an RB is established for each device, such as E1, E2, ..., En in Figure 3. Each RB represents the QoS of the device at the AS layer. The AS layer guarantees radio resource transmission according to the QoS parameter index of each RB.

The function body that processes the control command can be Radio Resource Control (RRC), or it can be a layer 3 (L3) or layer 2 (L2) data plane processing function body, such as a layer 3 user plane (L3UP ), Simple Distributed File Transfer System Access Protocol (Simple DFS Access Protocol, SDAP), Packet Data Convergence Protocol (Packet Data Convergence Protocol, PDCP), Radio Link Control (Radio Link Control, RLC), etc., can also be RRC and The combination of L3 or L3 data plane functions, for example, after RRC receives the NAS PDU sent by the core network, it selects the corresponding RB for the NAS PDU according to the D ID, and then sends the RB ID and NAS PDU to the data plane processing function, and then Build the corresponding PDU and send it to the MAC layer.

After the MAC receives the data from the RB, it sends it over the air interface according to the transmission requirements defined by the QoS parameters of the RB.

For terminal:

The MAC of the terminal receives the MAC PDU, parses it to obtain the RB ID and data packet, and obtains the D ID through the RB. Then carry the D ID and send the data packet to the NAS layer.

After receiving the D ID and NAS PDU data packets, the NAS layer of the terminal parses the NAS PDU and converts it into a command (Command) for each device (Device) and sends it to each device.

Downlink transmission is information sent from the terminal side to the network side. The terminal receives a command request from the network side, or performs data reporting according to certain rules (such as periodic reporting, subscription settings, data cache amount of the device, etc.). The uplink direction is described from the terminal's AS, NAS, various devices (D1...n in Figure 3, D is the abbreviation of Device, the same below), base station, core network, and APF.

For terminal:

The terminal equipment (D1...n in Figure 3) generates data (data for the user), and sends it to the NAS layer through the link between the APF and the NAS. There is no limit to the connection between APF and NAS, which can be realized by equipment, or through wifi, TCP socket connection, etc.

IP packets are constructed at the NAS layer, that is, the NAS at the sending end and the NAS at the receiving end perform data transmission through the end-to-end IP protocol. Each device is identified by an IP address, and each device has an IP flow to carry data.

After the AS layer receives the data of each device through the IP flow, it is mapped to different QoS flows and sent to the MAC layer according to the QoS requirements.

It should be noted here that the IP flow and QoS flow here are different from those in the current 5G. This name is used here mainly to represent the characteristics of the data: IP flow represents a Device and an IP address, and its data is unified on a data flow. ;QoS flow indicates that the data packets (mapped according to the data packets) are classified according to the wireless QoS requirements.

For base stations:

The MAC layer of the base station and the QoS Flow send the received data packets to the upper layer. The upper layer completes the continuation of the data packet and maps it to the corresponding IP flow; the base station sends the data to the core network through the IP flow.

For CN:

The core network indexes to a specific user according to the IP flow and the UE's identity ID, and then conducts a comprehensive analysis based on the data of all the devices of the user based on the user as a unit, and the analysis result is data for the application layer.

For APF:

After the APF receives the data, it can use AI tools to analyze the data, and map the twins of the devices according to the user and each device, and present them.

In summary, at least one embodiment of the present application can achieve the following intended effects:

1. The AS layer and NAS layer establish a user-centered context management mechanism;

2. Able to conduct comprehensive analysis of various wearing information centered on the user;

3. Realized the integration of industry and network;
