[0086] Please refer to Figure 9 , Figure 9 This is a schematic diagram of the terminal and the target plane protocol stack of the wireless access network according to an embodiment of this application. Figure 9 In this context, the second target plane network function instance, also known as the radio access network target plane network function instance, has a first sublayer that can carry messages exchanged between the terminal side and the second target plane network function instance.

[0088] Currently, the bearers corresponding to the control plane and user plane of communication are the Signalalling Radio Bearer (SRB) and the Data Radio Bearer (DRB), respectively. In this application embodiment, a new type of radio bearer, the first type, can be added for the target plane. This newly defined radio bearer, compared to reusing the SRB bearer, can solve the problems of target plane interaction affecting RRC signaling transmission and the limited data volume that the control plane can carry; compared to reusing the DRB bearer, it can solve the problems of data transparency within the user plane bearer to the radio access network and the differences between the data processing requirements of the target plane and the user plane.

[0090] Method 1: Create multiple Type I radio bearers, the multiple Type I radio bearers including: a Type I radio bearer for transmitting control information between the terminal and the target plane network function instance of the radio access network; a Type I radio bearer for transmitting data information between the terminal and the target plane network function instance of the radio access network; and a Type I radio bearer for transmitting control information and data information between the terminal and the target plane network function instance of the core network.

[0091] Method 2: Establish at least one Type I radio bearer, which is used to transmit control information and data information between the terminal and the target plane network function instance; that is, Method 2 is to transmit control information and data information with the same bearer.

[0092] Optionally, in method 2, multiple Type I radio bearers are created. Different Type I radio bearers have different QoS requirements for target plane data transmission and / or different data termination points. The data termination point includes at least one of the following: a radio access network target plane network function instance, a core network target plane network function instance, or an application function instance. Optionally, to facilitate controllable overhead on the terminal side, a maximum number of Type I radio bearers needs to be set.

[0093] Optionally, in method 2, a new first-type wireless bearer can also be created.

[0094] Method 3: Establish at least one Type I radio bearer, which is used to transmit data information between the terminal and the target plane network function instance, and transmit control information between the terminal and the target plane network function instance through RRC messages (e.g., RRC reconfiguration) and / or signaling radio bearers.

[0095] Optionally, in method 3, multiple first-type radio bearers are created, wherein different first-type radio bearers have different QoS requirements for target plane data transmission and / or different data termination points. The data termination point includes at least one of the following: radio access network target plane network function instance, core network target plane network function instance, and application function instance.

[0096] Optionally, to facilitate controllable overhead on the terminal side, it is necessary to set the maximum number of Type I wireless bearers.

[0097] Optionally, when multiple control information and / or data information needs to be transmitted through the first type of radio bearer, one control information (group) and / or data information (group) can be transmitted using one of the three methods; the other control information (group) and / or data information (group) can be transmitted using another of the three methods. The two methods can be different; for example, data information with subscription ID 1 can establish and transmit the first type of radio bearer using method 1, while data information with subscription ID 2 can propose and transmit the first type of radio bearer using method 2.

[0098] That is, the target plane's radio bearer includes: at least one type of first radio bearer, which is used to transmit one or more of the following information: control information between the terminal and the target plane network function instance; data information between the terminal and the target plane network function instance; and control information and data information between the terminal and the target plane network function instance.

[0099] or,

[0100] The target plane radio bearer includes: at least one first type radio bearer and an SRB, wherein the at least one first type radio bearer is used to transmit data information between the terminal and the target plane network function instance, and the SRB is used to transmit control information between the terminal and the target plane network function instance.

[0101] The first type of radio bearer is not an SRB or DRB, and the target plane network function instance includes at least one of the radio access network target plane network function instance and the core network target plane network function instance.

The data termination point includes at least one of the following: a radio access network target plane network function instance, a core network target plane network function instance, and an application function instance. Optionally, to facilitate controllable overhead on the terminal side, a maximum number of first type radio bearers needs to be set.

[0103] In this embodiment of the application, optionally, the wireless bearer of the target surface is determined according to at least one of the following:

[0104] 1) The data type that needs to be transmitted;

[0105] For example, data types can include at least one of the following: location data, MDT data, sensing data, computational data, etc.; data types can also be defined according to data size and time interval. For example, data types can include one of the following: specifying data size and specifying sending time, specifying data size and specifying sending time.

[0106] 2) The comparison result between the size of the data information and / or control information to be transmitted and the preset threshold.

[0107] For example, when the size of the data and / or control information to be transmitted is less than (or not greater than) a preset threshold, it is transmitted by multiplexing RRC messages (e.g., RRC reconfiguration) and / or existing SRBs; when the size of the data and / or control information to be transmitted is not less than (or greater than) the preset threshold, a first-class radio bearer is established for the transmission of data and / or control information.

[0108] In this embodiment of the application, the target plane establishment process is used to establish a target plane connection, including the establishment of the first type of radio bearer. This process can be initiated by the terminal or by the network side.

[0109] When the target plane establishment process is initiated by the terminal, optionally, the terminal uses the first sublayer to transmit target plane information with the target plane network function instance over the air interface, including: the terminal uses the first sublayer to send a first request message over the air interface, the first request message being used by the terminal to request the establishment of a target plane connection with the target plane network function instance. That is, the terminal initiates the establishment of the target plane connection.

[0110] Optionally, the first request message includes at least one of the following information for assisting in establishing a target surface connection:

[0111] 1) The identifier of the terminal;

[0112] Data transmission on the target plane requires immutability or associativity within a specific data collection or distribution time interval, enabling the target plane to correlate relevant data and form a dataset that meets a specific objective. Therefore, the terminal's identifier can be assigned by the target plane network function instance. The advantage of this approach is that it decouples from the IDs used in existing communication, ensuring isolation between the target plane and the communication plane and avoiding security issues caused by ID leakage on one side. Alternatively, short-term IDs that meet validity requirements in existing communication can be reused depending on the scenario. The use of persistent UE IDs such as Subscription Permanent Identifiers (SUPIs) is not recommended.

[0113] Alternatively, the identifier of the terminal may be assigned by the target plane network function instance, or it may be a terminal ID with a validity period requirement.

[0114] 2) Reason for the target plane connection establishment request;

[0115] The reasons for instructing the terminal to request the establishment of a target plane connection include reporting data that needs to be stored in the user's personal data anchor point, and meeting the network configuration conditions for triggering the terminal to report.

[0116] 3) The establishment method of the first type of wireless bearer that needs to be newly established, the first type of wireless bearer is used for the transmission of control information and / or data information of the target surface;

[0117] The default setup method is to create the first Class 1 wireless bearer.

The number of wireless bearers in the Class I wireless bearer type indication list is from 0 to the maximum number of Class I wireless bearers.

[0125] Optionally, the target plane capability information of the terminal includes: target plane capability information related to the reason for the target plane connection establishment request, or all target plane capability information of the terminal.

[0126] In the above embodiments, a connection to the target plane is established by sending a new first request message. In other embodiments of this application, the terminal may also use existing RRC messages to establish a connection to the target plane.

[0140] Data transmission on the target plane requires immutability or associativity within a specific data collection or distribution time interval, enabling the target plane to correlate relevant data and form a dataset that meets a specific objective. Therefore, the terminal's identifier can be assigned by the target plane network function instance. The advantage of this approach is that it decouples from the IDs used in existing communication, ensuring isolation between the target plane and the communication plane and avoiding security issues caused by ID leakage on one side. Alternatively, short-term IDs that meet validity requirements in existing communication can be reused depending on the scenario. The use of persistent UE IDs such as Subscription Permanent Identifiers (SUPIs) is not recommended.

[0141] Alternatively, the identifier of the terminal may be assigned by the target plane network function instance, or it may be a terminal ID with a validity period requirement.

[0142] 2) Configuration information for newly created / reconfigured Type I radio bearers, including type and quantity indication information. Optionally, it may also include PDCP layer configuration information and RLC layer configuration information.

[0147] In the above embodiments, the establishment of the target plane connection is initiated by the terminal, but it can also be initiated by the network side.

[0148] When the target plane establishment process is initiated by the network side, optionally, the terminal uses the first sublayer to transmit target plane information with the target plane network function instance over the air interface, including: the terminal uses the first sublayer to receive a second request message over the air interface, the second request message being used by the target plane network function instance to request the establishment of a target plane connection with the terminal. That is, the network side initiates the establishment of the target plane connection.

[0149] Optionally, the second request message includes at least one of the following information for establishing a target surface connection:

The number of wireless bearers in the Class I wireless bearer type indication list may be 0 to the maximum number of Class I wireless bearers.

[0157] 5) Air interface resource scheduling methods for the target plane;

[0158] Optionally, the air interface resource scheduling method includes at least one of the following: dynamic scheduling method, semi-static scheduling method, dedicated terminal resources, and multiple terminals competing for resources.

[0159] Dynamic scheduling refers to the process by which a terminal can dynamically schedule data plane resources for a terminal through scheduling requests, and / or the network can schedule resources based on the terminal's target plane configuration information; semi-static scheduling refers to the pre-scheduling instructions given by the network side and the terminal side based on a variety of pre-agreed scheduling methods.

[0160] 6) The target surface capability information of the terminal;

[0161] Optionally, the target plane capability information of the terminal includes: target plane capability information related to the reason for the target plane connection establishment request, or all target plane capability information of the terminal.

[0170] 11) Valid status indications for information used to establish target surface connections.

[0171] That is, whether the above 1)-10) are valid. For example, valid in RRC connected state, valid in target surface open state, etc.

[0172] In the above embodiments, optionally, in the embodiments of this application, the target surface capability information may include at least one of the following:

[0173] 1) Indicate whether the terminal supports information about the target surface;

[0174] When designing a terminal, target plane functions for the UE can be supported as needed based on the target user and / or hardware / software planning. When the target plane is not supported, the overhead on the UE side is minimized.

[0175] In addition, the support for target surface capabilities can be dynamically updated.

[0176] 2) Information indicating that the target surface capability is the capability of a single terminal or a group of terminals, wherein the terminal group includes at least two terminals;

[0177] The above scenarios can occur when a user's multiple terminals form a terminal group, which may include one or more terminals such as mobile phones, smartwatches, and glasses. These scenarios can also occur when multiple terminals are connected via sidelinks. Furthermore, these scenarios can occur when multiple terminals within a network configuration interact with each other through mobile access network base stations and / or the core network.

[0178] In this embodiment of the application, the terminal group includes at least one 3GPP terminal, and may also include one or more non-3GPP terminals. In 3GPP communication, a 3GPP terminal is generally defined as a UE (Mobile Phone, Customer Premise Equipment (CPE)) terminal that has a Subscriber Identification Module (SIM), Embedded-SIM (eSIM), or MUSIM, etc. Non-3GPP terminals include, for example, wristbands, watches, or other health monitoring devices that connect to the UE via Wi-Fi or Bluetooth.

[0179] In this embodiment of the application, the capabilities of the terminal group can be reported by a 3GPP terminal in the terminal group.

[0180] 3) Information indicating whether the target surface capability is a static capability or a dynamic capability;

[0181] In this embodiment, static capability refers to the target plane capability being static and not dynamically adjusted. For example, static capability can be the maximum or minimum target plane capability that the UE can support, and this capability can be set by the UE according to its own hardware design and / or resource allocation. Dynamic capability refers to the target plane capability being dynamic and can be dynamically adjusted. For example, dynamic capability is dynamically adjusted and updated according to the UE's communication load. When the target plane capability is static, the corresponding target plane capability information remains unchanged after the UE reports or the network queries it. When the target plane capability includes both static and dynamic capabilities, the maximum or minimum target plane capability is usually used as the upper or lower limit of the target plane capability, and its current capability status is dynamically decided based on influencing factors.

[0182] 4) Supported target capability reporting methods;

[0183] In this embodiment of the application, the target plane capability reporting method may optionally include at least one of the following: proactive capability update reporting, reporting based on network configuration change conditions, and network query reporting.

[0184] 5) Information indicating whether the target plane capability reporting method configured on the network side is supported;

[0185] In this embodiment of the application, optionally, if the target plane capability reporting method configured by the network side is not supported, the update is performed according to the supported default target plane capability reporting method; if the target plane capability reporting method configured by the network side is supported, the update is performed according to the target plane capability reporting method configured by the network side.

[0186] 6) Supported target surface data reporting modes;

[0187] In this embodiment of the application, the target plane data reporting mode may optionally include: subscription reporting and / or default data collection reporting. Subscription reporting refers to the network function and the UE determining the data and / or measurements or reporting conditions to be reported through interaction, and then reporting the data accordingly. Default data collection reporting refers to the UE reporting the agreed-upon data by default based on pre-agreed data collection items between the network function and the UE, or the UE reporting the agreed-upon data based on the on / off status of its own target plane and / or the network side's enabling or disabling of data collection.

[0188] 7) Data types supported by the target surface;

[0189] In this embodiment of the application, the target surface may optionally support data types including at least one of the following: communication data, sensing data (also known as sensing service data, potentially including at least one of the following: transmission of sensing measurement results / sensing measurement values, sensing signals, and measurements to assist in sensing resource scheduling), computing power data (also known as computing power service or computing service data, potentially including at least one of the following: input data of computing services, output data, and measurements to assist in computing resource scheduling), artificial intelligence (AI) data (also known as AI service data, potentially including at least one of the following: data collection for AI model training / evaluation, preprocessed data, model data, input / output data for model inference, and measurements to assist in AI resource scheduling), user subscription data, network operation data, and digital twin data.

[0190] 8) Supported transmission directions of the target surface;

[0191] In this embodiment of the application, optionally, the supported transmission directions of the target plane include uplink and / or downlink. Typically, the target plane's control information exchange capability includes both uplink and downlink. Regarding the target plane's data exchange capability, if uplink is supported, it means that the UE supports data reporting from the target plane; if downlink is supported, it means that the UE supports receiving data from the target plane.

[0192] For example, communication data reporting can be communication measurement data required for communication service quality optimization; perception data reporting can be perception measurement quantities required for perception; computing or AI data reporting can be computing input and / or output data required for computing; communication data receiving can be data information required for UE local communication decision-making; perception data receiving can be receiving perception measurement quantities or perception results required for local perception or decision-making; and computing data receiving can be receiving computing input and / or output data.

[0193] 9) Supported maximum data uplink rate for the target surface;

[0194] The maximum supported uplink data rate can also be expressed as the maximum supported data collection rate or the maximum reporting rate. To avoid the difficulty in representing this item due to its large continuous data range, different rate ranges can be defined as different rate levels. In this case, only the level information needs to be given, improving the representation efficiency.

[0195] 10) Supported maximum downlink data rate for the target surface;

[0196] This item can also be expressed as the maximum supported data usage rate, maximum data distribution rate, or maximum receiving rate. Similarly, different rate ranges can be defined as different rate levels, in which case this item only needs to provide level information, improving representation efficiency.

[0197] 11) The total buffer size of the target surface;

[0198] This item can be the total buffer size of all protocol layers, or the total buffer size of each layer, such as the total buffer size of Layer-2 and / or the total buffer size of Layer-3.

[0200] The target surface functionality may include at least one of the following: data collection, data distribution, data security, data privacy, data analysis, and data preprocessing.

[0201] 13) The maximum number of data collection items supported;

[0202] Because data collection requires corresponding hardware resources and software processing support, this item indicates the maximum number of data collection items that can be supported simultaneously. For example, it can simultaneously support the collection of two data items: Reference Signal Received Power (RSRP) and Reference Signal Received Quality (RSRQ). This item can represent the maximum number of data collection items that can be supported for all data. When data is classified or categorized, this item can also represent the maximum number of data collection items supported for a specific category or level of data.

[0203] 14) Supported ID sequence number size;

[0204] For example, during data collection configuration, a data collection subscription ID is usually sent to the UE. The length of this ID can be represented by how many bits. When the UE needs to use data provided by the target plane, there is also a corresponding data receiving subscription ID.

[0205] 15) Supported minimum time granularity of data collection;

[0206] Indicates the minimum time granularity of the data that the UE can collect. For example, for RSRP, the minimum time granularity is each transmission time interval (TTI).

[0207] 16) Supported minimum time granularity for data reporting;

[0208] Once the required data for the target plane is collected, the UE can report it at the fastest interval. Based on this capability information, the base station can configure and schedule target plane resources for the UE's data collection.

[0209] 17) The maximum length of a single target plane message supported;

[0210] This message can be used for data reporting and / or data reception.

[0211] 18) Indicate whether the terminal supports connected state data collection and reporting;

[0212] 19) Indicates whether the terminal supports data collection and reporting in idle and / or inactive states;

[0213] 20) Information indicating whether the terminal supports the continuity of the target surface across states.

[0214] That is, the target plane configuration and control information when the UE switches from one state to another, and whether the data interaction of the target plane is continuous.

[0215] Optionally, after receiving the second request message, the UE decides whether to accept the target plane connection establishment request based on the information in the second request message and relevant UE-side information (such as target plane capability, transmit power margin, etc.), and sends a second request response message. If the second request is accepted, the response message includes acceptance indication information, and optionally, the response message may include the terminal's identifier. If the second request is rejected, the response message includes rejection indication information, and optionally, the response message may include a rejection reason. The rejection reason may be one or more of the following: target plane capability not met, insufficient resources, or no target plane data.

[0216] In this embodiment of the application, optionally, before the terminal uses the first sublayer to transmit target plane information between the air interface and the target plane network function instance, the method further includes: the terminal determining the state of the first sublayer of the terminal, the state of the first sublayer of the terminal including: an on state (or an active state) and an off state (or a closed state).

[0217] In the disabled state, for terminals that support target plane functionality, this state means that the target plane functionality is disabled or prohibited from being enabled; or for terminals that do not support target plane functionality, from the perspective of the first sublayer of the radio access network, the state of the terminal is also disabled.

[0218] In this embodiment of the application, optionally, the terminal determines the state of the first sub-layer of the terminal based on the terminal's hardware configuration information and / or software configuration information.

[0219] In this embodiment of the application, optionally, the terminal determines that the state of the first sublayer of the terminal is prohibited if at least one of the following conditions is met:

[0220] 1) The hardware of the terminal does not support the target plane function;

[0221] 2) The target surface function of the terminal is disabled.

[0222] In one scenario, although the terminal supports the target plane function in its hardware design, the user disables the target plane function for reasons such as power consumption and privacy. Therefore, the first sub-layer of the target plane of the terminal is in a prohibited state.

[0223] In one scenario, one or more target plane functions may be prohibited due to geographical location (e.g., a tracking area or RAN-based notification area). If the prohibited service is a supported target plane function for a given terminal, then the target plane's first sublayer state for that terminal will be prohibited. In other words, the state of the target plane's first sublayer can be defined based on each target plane function and can be automatically adjusted by the terminal according to relevant factors or adjusted according to network configuration.

[0224] In this embodiment of the application, optionally, the terminal determines that the state of the first sublayer of the terminal is enabled if at least one of the following conditions is met:

[0225] 1) The terminal's hardware supports the target plane function, and the target plane function cannot be turned off;

[0226] 2) The terminal's hardware supports target plane functionality and all target plane functions are enabled;

[0227] This applies to situations where the terminal supports one target surface function, as well as situations where the terminal supports multiple target surface functions.

[0228] 3) The terminal's hardware supports target plane functions, and at least one target plane function of the terminal is enabled.

[0229] In one scenario, due to factors such as geographical location (e.g., tracking area or RAN-based notification area), one or more functions of the target area are enabled, therefore the first sub-layer of the target area for the terminal is in an enabled or activated state. For example, when the terminal enters a nature reserve or uninhabited area, it may enable positioning and other sensing functions for safety or regulatory reasons.

[0230] This applies to situations where the terminal supports multiple target surface functions.

[0231] In this embodiment, the state of the first sub-layer can be switched as needed. Optionally, the target plane data transmission method further includes: the terminal adjusting the state of the first sub-layer of the terminal.

[0232] In this embodiment of the application, optionally, before the terminal adjusts the state of the first sub-layer of the terminal, the method further includes:

[0233] The terminal decides whether to adjust the state of the first sublayer based on relevant information on the terminal side (such as location and / or battery level) and / or target plane capability information on the receiving network side (such as target plane data types and / or data items configured on the network side).

[0234] and / or

[0235] The terminal receives a state modulation indication sent by the network side, and the state adjustment indication is used to adjust the state of the terminal's first sublayer.

[0236] When the first sublayer is in the open state, the state of the target plane of the terminal includes at least one of the following, depending on the connection and / or interaction between the terminal and the target plane on the network side: idle state, connected state, and disconnected state.

[0237] Please refer to Figure 11 , Figure 11 The embodiment shown illustrates a switching method for the state of a first sub-layer. When one or more target surface functions are enabled, the first sub-layer switches to the enabled state; when the target surface functions are disabled, the first sub-layer switches to the disabled state.

[0238] That is, in this embodiment of the application, optionally, before the terminal uses the first sublayer to transmit target plane information between the air interface and the target plane network function instance, the method further includes:

[0239] If the first sub-layer is in the open state, the terminal determines the state of the target surface, and the state of the target surface includes one of the following: idle state, connected state, and disconnected state;

[0240] In the idle state, there is no data transmission to the target plane, the target plane connection is released, and / or the first type of radio bearer is deleted; that is, data transmission to the target plane cannot be performed, there is no first sublayer context, and there is no target connection to the core network and the radio access network.

[0241] In the connected state, a target plane connection is established, and / or, data transmission of the target plane is performed based on the target plane connection; that is, data transmission of the target plane can be performed, there is a first sublayer context, and the terminal establishes a target plane connection with the radio access network.

[0242] In the disconnected state, the target plane connection is released, and / or, data transmission on the target plane is performed based on configuration information from the connected state or configuration information from the idle state. That is, data transmission on the target plane is possible when there is a first sublayer context, the terminal and the wireless access network have not established a connection on the target plane, and data transmission is performed through resources pre-configured in the first sublayer or configuration information receivable in the disconnected state.

[0243] Please refer to Figure 12 The state of the target surface can be switched according to different conditions of the target surface.

[0244] In the above embodiments, the state of the target plane is decoupled from (unrelated to) the RRC state. Considering that the purpose of 6G's potential sensing, digital twin, computing and other services is not communication, if the data required by the relevant services is carried through the target plane, the target plane function can be completed through the state definition and transformation of the independent first sub-layer of the target plane.

[0245] In this embodiment, the state of the target plane can also be related to the RRC state. Considering the potential 6G services such as sensing, digital twins, and computing, although their ultimate purpose is not communication, the service process typically involves control information or data interaction. Therefore, if the data required for related services is carried through the target plane, the state of the target plane can be defined and transformed through joint design with the existing RRC state.

[0246] In this embodiment of the application, optionally, before the terminal uses the first sublayer to transmit target plane information between the air interface and the target plane network function instance, the method further includes at least one of the following:

[0247] If the terminal is in the RRC idle state (RRC_IDLE), the terminal determines that the state of the target surface is idle;

[0248] If the terminal is in RRC connected state (RRC_CONNECTED) and / or RRC inactive state (RRC_INACTIVE), the terminal determines the state of the target surface as idle state, non-connected state, or connected state.

[0249] In this embodiment, RRC and / or the first sublayer are responsible for maintaining the state information of the first sublayer of the target plane of the radio access network, and for sending and receiving messages related to the state transition of the first sublayer of the target plane. The state transition of the first sublayer of the target plane is based on the establishment of an RRC connection. The state transition of the first sublayer of the target plane only occurs when the terminal is in an RRC connected state or an inactive state.

[0250] Please refer to Figure 13 The state of the target surface can be switched according to different RRC states.

[0251] Please refer to Figure 14 This application also provides a target plane data transmission method, including:

[0252] Step 14: The network-side device uses the first sublayer to transmit target plane information between the terminal and the target plane network function instance over the air interface, wherein the target plane is a protocol function plane used to support at least one of data collection, data distribution, data security, data privacy, data analysis and data preprocessing.

[0253] Optionally, the first sublayer's functions in the air interface include at least one of the following:

[0265] Please refer to Figure 15 , Figure 15 This is a schematic diagram of the target plane protocol stack of a network-side device according to an embodiment of this application. The protocol stack includes: a first sublayer, a PDCP layer, an RLC layer, a MAC layer, and a PHY layer. Of course, the protocol sublayers below the first sublayer can be other types (e.g., the protocol stack structure includes: a first sublayer, a PDCP layer, a MAC layer, and a PHY layer), and this embodiment of the application does not limit this.

[0266] Optionally, the establishment method of the wireless bearer of the target surface includes at least one of the following:

This scheme supports end-to-end target plane information transmission between the core network target plane network function instance and the UE, as well as target plane information transmission between the radio access network target plane network function instance and the UE. By introducing the first sublayer of the layer sublayer protocol, problems such as the impact of target plane interaction on RRC signaling transmission and the limited data capacity of the control plane can be solved; it also solves the problems of data transparency within the user plane to the radio access network and the differences in data processing requirements between the target plane and the user plane. If the data is transparent to the radio access network, it may lead to the UE needing to report to both the radio access network and the core network separately when the data required by the radio access network target plane and the core network target plane are the same, resulting in high air interface overhead and low efficiency. The quality of service required for the target plane control information and target plane data information can be flexibly set according to specific application scenarios. Simultaneously, the UE can flexibly disable or enable the target plane function according to hardware configuration and / or software configuration and / or user wishes, providing more space and choice for UE design and users.
