[0062] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them.

The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described technology can be used for the systems and radio technologies mentioned above as well as for other systems and radio technologies. The following description describes a New Radio (NR) system for example purposes, and NR terminology is used in most of the following description, but these technologies can also be applied to applications other than NR system applications, such as 6th Generation (6G) communication systems.

[0065] The information transmission method, terminal, and network device provided in the embodiments of the present application are described in detail below with reference to specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0066] like Figure 1 As shown, at least one embodiment of the present application provides an information transmission method, applied to a terminal, comprising:

[0067] Step 101: Obtain binding information between a terminal and at least one device and a mapping relationship between at least one device and a radio bearer RB;

[0068] Step 102: Based on the binding information and the mapping relationship, information is transmitted with the first network device to achieve unified management of the at least one device.

[0069] It should be noted that the first network device is a device on the access network side, for example, it can be a base station.

[0070] Optionally, in at least one embodiment of the present application, the mapping relationship is configured for the terminal by the first network device, that is, the first network device must first establish a mapping relationship between at least one device bound to the terminal and the RB, and then send the mapping relationship to the terminal. The terminal stores the mapping relationship, and when information interaction is required, the information is parsed based on the mapping relationship.

[0071] Optionally, 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 the terminal identifier and the device identifier.

[0072] It should be noted that the second network device is a device on the core network side, for example, a core network element.

[0073] Specifically, the second network device obtains the binding information through the following steps:

[0074] Assigning a terminal identifier to the terminal;

[0075] assigning a device identifier to at least one device associated with the terminal;

[0076] The terminal identifier is bound to the device identifier to obtain binding information between the terminal and at least one device.

[0077] It should be noted that at least one embodiment of the present application establishes binding information between a terminal and at least one device and a mapping relationship between at least one device and RB, so that information for different devices can be transmitted simultaneously and processed uniformly, thereby realizing network integration of different devices.

[0078] It should be noted here that the device mentioned in the embodiments of the present application mainly refers to the user's wearable device.

[0079] The following first describes in detail the application scenario of at least one embodiment of the present application.

[0080] The embodiment of the present application proposes a terminal context solution for network-industry convergence centered on digital twin users, aiming at the demand for more user-centric information processing models in the next generation of mobile communications. By defining the context mode of UE in the non-access (Non Access Stratum, NAS) layer (it should be noted that the NAS layer corresponds to the function of the core network on the network side) and the access (Access Stratum, AS) layer (it should be noted that the AS layer corresponds to the function of the access network (for example, base station) on the network side), a context solution with UE as the key retrieval key is implemented, and the information of all device measurements related to the user can be obtained through the terminal identification (for example, UE ID or UE identity identification).

[0081] Define user-centric contextual solutions for different scenarios. Three scenarios:

[0082] Scenario 1: All devices worn by the same user are uniformly connected to a terminal (optionally, the terminal refers to a terminal held by the user), and connected to the network side through the terminal to establish context information.

[0083] Scenario 2: All devices worn by the same user can be connected to the network independently.

[0084] Scenario 3 is a mixture of Scenario 1 and Scenario 2.

[0085] It should be noted that the above three scenarios require a unified UE context solution. Based on this, the embodiment of this application proposes a protocol function solution for network integration centered on digital twin users, mainly including:

[0086] For all wearable IoT devices owned by the user, an index information table centered on the user is established on the network side. The index information table contains information about all wearable IoT devices bound to the user. Figure 2 shown.

[0087] 1. User information: The basic context of the user, such as the allocation of a Cell-Radio Network Temporary Identifier (C-RNTI), a Subscription Concealed Identifier (SUCI), a Subscription Permanent Identifier (SUPI), a Globally Unique Temporary Identifier (GUTI), or other system-defined identification identifiers as the UE ID after the UE accesses the network. A signaling radio bearer (SRB) is then established for signaling transmission. The user at this time can be a handheld terminal or one of the user's wearable IoT devices. The user's ID, denoted as UEkey ID, represents the primary ID of the UE.

[0088] In addition, it also includes the user's NAS function information, such as the configuration information of the access and mobility management function (AMF), user plane function (UPF) and other functions.

[0089] 2. Wearable IoT Device Identity: Each wearable IoT device is assigned an identity ID, denoted as D1…n ID. This ID is the user's internal ID and is an appendage of the UEkey ID. Using D1…n ID as an index, it describes the characteristics of each device.

[0090] 3. Bearer: For each device identified by D1…n ID, a dedicated radio bearer is established.

[0091] Figure 2 The presentation of devices at the application layer (AP), NAS, and AS is given in the document. The AP layer is primarily presented as a digital twin. For example, a UE has multiple digital twins, each corresponding to a device. The NAS layer establishes a user device ID (DID) to identify each device under the user. The AS layer establishes several radio bearers (IP flows, identifying each device by IP address) for each UE. Each radio bearer corresponds to a device, and during air interface transmission, the data on each radio bearer is mapped to different air interface transmission bearers (identified by QoS flows) according to the quality of service (QoS) transmission requirements for air interface transmission.

[0092] Since information transmission includes uplink transmission and downlink transmission, through the above-mentioned protocol function, in at least one embodiment of the present application, for downlink transmission, an optional implementation of step 102 is:

[0093] The media access control (MAC) layer receives first information sent by the first network device, where the first information includes identification information of the RB and a data packet. It should be noted that the data packet may be a control instruction for the device, such as a data collection instruction.

[0094] Determining, based on a mapping relationship between the at least one device and the RB, a device identifier of at least one target device corresponding to the RB;

[0095] The non-access 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.

[0096] It should be noted that downlink data is sent from the network side to the terminal. Normally, the application function (APF) receives the user's data collection instructions for multiple devices, and then transmits the instructions to the terminal through the core network and access network. The terminal parses the instructions and sends them to the corresponding device. The device collects the corresponding data according to the instructions.

[0097] For uplink transmission, the optional implementation of step 102 is:

[0098] The NAS layer obtains user data of the target device and generates a NAS data packet, wherein the NAS data packet includes a device identifier of the target device;

[0099] The AS layer receives the NAS data packet via a data stream, maps the NAS data packet to a quality of service stream, and sends it to the MAC layer. Each target device corresponds to a data stream, and each data stream corresponds to a quality of service stream. The data stream includes user data.

[0100] The MAC layer sends the user data to the first network device based on the quality of service flow.

[0101] 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. The core network obtains comprehensive data for the user by performing comprehensive analysis and processing on the data, and finally transmits the data to the APF, which presents the data.

[0102] The uplink transmission and downlink transmission are described in detail below.

[0103] Figure 3 A network-industry convergence protocol stack solution centered on "digital twin users" is presented. In the entire protocol stack solution, the downlink mainly transmits the signaling and control information sent by the network layer, and the uplink mainly completes the reporting of monitoring information (data) according to the signaling and control on the network side.

[0104] Downlink transmission is the information sent from the network side to the terminal side, which generates commands for wearable devices through user-oriented operations. The downlink direction is from APF, core network, base station and terminal AS, NAS, various devices ( Figure 3 Dn in the figure, D is the abbreviation of Device, the same below) is used for description.

[0105] The main implementation process of the downstream network side is as follows:

[0106] APF has an operational user interface (UI). In APF, a digital twin (DTE) of the user is created to record the user's main characteristics and the characteristics of the wearable devices carried by the user. The user and the various devices carried by the user are presented through the operation interface and can be operated.

[0107] For the core network (CN): It can receive commands or requests sent by the APF. After analyzing the command or request, it generates corresponding NAS signaling according to the requirements of the command or request.

[0108] It should be noted that a context control system based on the user is established in the CN, including the D1…n ID of each device. When the CN sends NAS signaling for the wearable device of the user to the base station, it carries the D ID of the device.

[0109] The CN transmits NAS signaling via the interface between the CN and the base station. Figure 3 The TNL layer in the protocol is the Transport Network Layer. Based on TNL, the Radio Network Layer (RNL) protocol (such as the Stream Control Transmission Protocol (SCTP)) can be introduced, or the TNL transport protocol can be used directly for transmission without introducing it.

[0110] Base Station: After receiving the NAS protocol data unit (PDU) through the interface with the CN, it obtains the user's bound device identification information through the carried DID and indexes the radio bearer (RB) that carries the device.

[0111] The base station establishes a context information unit based on the UE. The primary ID of the user is the C-RNTI of the UE, or an ID that is not related to the air interface cell where the UE is located (for example, a base station is used as a unit to assign a unique ID within the base station to the UE, and this ID does not change when the cell where the UE is running on the base station is switched). Based on the UE ID, an RB is established for each device, such as Figure 3 Each RB represents the QoS of the device at the AS layer. The AS layer ensures wireless resource transmission based on the QoS parameters of each RB.

[0112] The function that processes the control command can be radio resource control (RRC), or a layer 3 (L3) or layer 2 (L2) data plane processing function, such as layer 3 user plane (L3UP), simple distributed file transfer system access protocol (SDAP), packet data convergence protocol (PDCP), radio link control (RLC), etc. It can also be a combination of RRC and 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 carries the RB ID and NAS PDU to the data plane processing function, and then assembles the corresponding PDU and sends it to the MAC layer.

[0113] After receiving the data from the RB, the MAC sends it over the air interface according to the transmission requirements defined by the RB's QoS parameters.

[0114] For terminals:

[0115] The terminal's MAC receives the MAC PDU, parses it to obtain the RB ID and data packet, obtains the D ID from the RB, and then sends the data packet to the NAS layer with the D ID.

[0116] After receiving the D ID and NAS PDU data packets, the NAS layer of the terminal parses the NAS PDU and converts it into commands for each device and sends it to each device.

[0117] Downlink transmission is the information sent from the terminal side to the network side. The terminal receives the command request from the network side, or reports data according to certain rules (such as periodic reporting, subscription settings, device data cache, etc.). The uplink direction is from the terminal's AS, NAS, various devices ( Figure 3 D1…n in the figure, where D is the abbreviation of Device, the same below) and base stations, core networks, and APFs are described.

[0118] For terminals:

[0119] Terminal equipment ( Figure 3 The data (D1…n) in the APF is generated and sent to the NAS layer through the link between the APF and NAS. The link between the APF and NAS is not restricted and can be implemented by the device, or through Wi-Fi, TCP socket connection, etc.

[0120] At the NAS layer, IP packets are formed. The sending and receiving NAS use the end-to-end IP protocol to transmit data. Each device is identified by its IP address, and each device has an IP flow to carry data.

[0121] After the AS layer receives data from each device through the IP flow, it maps it to different QoS flows according to the QoS requirements and sends it to the MAC layer.

[0122] It should be noted that the IP flow and QoS flow here are different from those in current 5G. These names are used here mainly to indicate the characteristics of the data: IP flow means one device has one IP address, and its data is carried on a unified data flow; QoS flow means that the data packets are classified according to the wireless QoS requirements (mapped according to the data packets).

[0123] For base stations:

[0124] The base station's MAC layer and QoS flow send received data packets to the upper layer. The upper layer completes the packet forwarding and maps it to the corresponding IP flow. The base station then sends the data to the core network via the IP flow.

[0125] For CN:

[0126] The core network indexes the specific user according to the IP flow and UE identity ID, and then performs a comprehensive analysis on the data of all the user's devices based on the user. The analysis results are application-layer data.

[0127] For APF:

[0128] After APF receives the data, it can use AI tools to analyze the data, map it to the device's twin according to the user and each device, and present it.

[0129] In summary, at least one embodiment of the present application can achieve the following beneficial effects:

[0130] 1. The AS layer and NAS layer establish a user-centric context management mechanism;

[0131] 2. Ability to conduct comprehensive analysis of various wearable information with users as the center;

[0132] 3. Achieved industry-network integration;

[0133] 4. Able to achieve precise QoS flow guarantee according to different devices.
