[0100] The following will be combined with the 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. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0101] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein, for example, are implemented in a sequence other than those illustrated or described herein.

[0102] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship. In the embodiments of this application, the term "plurality" refers to two or more, and other quantifiers are similar.

[0103] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions.

Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0104] The following is a brief description of the relevant concepts mentioned in this application.

[0105] Based on 3GPP's previous research, A-IoT has two topologies in terms of network architecture, including topology 1 and topology 2.

[0106] In Topology 1, the A-IoT device communicates directly and bidirectionally with the base station. Communications between the base station and the A-IoT device include A-IoT data and / or signals. This topology allows for the possibility that the base station used to transmit to the A-IoT device may be different from the base station used to receive data from the A-IoT device.

[0107] In topology 2, intermediate nodes between A-IoT devices and base stations enable bidirectional communication. In this topology, intermediate nodes can be relays, IAB nodes, user equipment (UE), repeaters, and more, enabling the implementation of ambient IoT. Intermediate nodes transmit A-IoT data and / or signaling between the base station and A-IoT devices.

[0108] The following describes embodiments of the present application in conjunction with the accompanying drawings.

The wireless communication system can be a system that adopts the fifth generation (5G) mobile communication technology (hereinafter referred to as a 5G system). Those skilled in the art will understand that the 5G NR system is only an example and is not limiting.

[0109] See also Figure 1 , Figure 1 This is a structural diagram of a network system that can be applied in the embodiment of the present application, such as Figure 1As shown, it includes a terminal 11 and a network-side device 12, wherein the terminal 11 can be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a notebook computer, a personal digital assistant (PDA), a handheld computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (MID), an augmented reality (AR), a virtual reality (VR) device, a robot, a wearable device (Wearable Device), an aircraft (flight vehicle), a vehicle user equipment (VUE), a ship-borne device, a pedestrian user equipment (PUE), a smart home (home appliance with wireless communication function, such as a refrigerator, a TV, a washing machine or furniture, etc.), a game console, a personal computer (PC), an ATM or a self-service machine, and other terminal-side devices.

The network side device 12 may include an access network device or a core network device, wherein the access network device may also be called a radio access network (Radio Access Network, RAN) device, a radio access network function or a radio access network unit. The access network device may include a base station, a wireless local area network (WLAN) access point (AccessPoint, AP) or a wireless fidelity (Wireless Fidelity, WiFi) node, etc.Among them, the base station can be referred to as Node B (NB), Evolved Node B (eNB), the next generation Node B (gNB), New Radio Node B (NR Node B), access point, Relay Base Station (RBS), Serving Base Station (SBS), Base Transceiver Station (BTS), radio base station, radio transceiver, Basic Service Set (BSS), Extended Service Set (ESS), Home Node B (HNB), Home Evolved Node B (home evolved Node B), Transmission Reception Point (TRP) or other appropriate terms in the relevant field. As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0110] The core network equipment may include but is not limited to at least one of the following: core network node, core network function, mobility management entity (MME), access mobility management function (AMF), session management function (SMF), user plane function (UPF), policy control function (PCF), policy and charging rules function unit (PCRF), edge application service discovery function (EASDF), unified data management (UDM), unified data repository (UDR), home user server (HSS), centralized network configuration (CNC), network storage function (NRF), network exposure function (NEF), local NEF (L-NEF), binding support function (BSF), application function ( Function, AF), etc. It should be noted that in the embodiments of the present application, only the core network device in the NR system is introduced as an example, and the specific type of the core network device is not limited.

[0111] The embodiments of the present application provide an information processing and transmission method, apparatus, access network equipment, and core network equipment to enable communication between A-IoT devices.

[0112] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0113] like Figure 2 As shown, an embodiment of the present application provides an information processing method, which is executed by an access network device, including:

[0114] Step S201: receiving authorization information of at least one terminal from a core network device;

[0115] Optionally, the terminal mentioned in the embodiments of the present application refers to an environmental Internet of Things device.

[0116] Step S202: providing services for a first terminal that is authorized among the at least one terminal according to the authorization information;

[0117] Optionally, the first terminal is one or more authorized terminals among the at least one terminal.

[0118] It should be noted that in the embodiment of the present application, the authorization information of the environmental Internet of Things device is issued through the core network device, so that the access network device can provide services for the authorized environmental Internet of Things device, thereby realizing the communication of the authorized environmental Internet of Things device and ensuring the communication reliability of the environmental Internet of Things device.

[0119] Optionally, the ambient Internet of Things (A-IoT) device mentioned in the embodiments of the present application may also be referred to as an enabled IoT device or a passive IoT device.

[0120] Optionally, in one implementation, the authorization information includes at least one of the following:

[0121] A11, first indication information of whether one or more terminals among the at least one terminal are authorized;

[0122] Optionally, in this case, each environmental Internet of Things device will correspond to a first indication information, and the first indication information is used to indicate whether the environmental Internet of Things device is authorized (authorized) or unauthorized (deauthorized, that is, not authorized); for example, the first indication information can be indicated by a bit, when the bit value is 1, it indicates authorization, and when the bit value is 0, it indicates unauthorization; or, for example, when the bit value is 0, it indicates authorization, and when the bit value is 1, it indicates unauthorization.

[0123] A12. a device type of the authorized terminal in the at least one terminal;

[0124] This situation can be understood as the core network device informing the access network device of the device type of the authorized environmental IoT device. That is to say, when the access network device receives the device type for a certain environmental IoT device, the access network device determines that the environmental IoT device is authorized and what type of device the environmental IoT device is.

[0125] Optionally, the device type may be a type determined by classifying based on the capabilities of the environmental Internet of Things device, or a type determined by classifying based on the working status of the environmental Internet of Things device.

[0126] For example, when classifying environmental IoT devices based on their capabilities, they can be divided into Type 1, Type 2, etc. Type 1 devices have energy storage capabilities, no downlink / uplink amplifiers, no independent signal generation capabilities, and need to transmit signals through backscattering; Type 2 devices have energy storage capabilities, downlink / uplink amplifiers, and the stored energy can be used to amplify the power of the backscattered signal. They have independent signal generation capabilities, and the uplink transmission can be generated by the device or performed through backscattering.

[0127] For example, when classifying environmental IoT devices based on their working status, they can be divided into static environmental IoT devices, dynamic environmental IoT devices, etc.

[0128] A13. Service type authorized for the at least one terminal;

[0129] It should be noted that in this case, it can be understood that the core network device notifies the access network device of the authorized service type for each environmental Internet of Things device. For example, environmental Internet of Things device 1 can perform service types 1, 2 and 3. The core network device notifies the access network device that the authorized service type for environmental Internet of Things device 1 is service type 2. Then the access network device can only provide services for service type 2 of environmental Internet of Things device 1, and the access network device cannot provide services for service types 1 and 3 of environmental Internet of Things device 1.

[0130] It should be noted that when the core network device configures authorization information, it is usually done for a single device, that is, each environmental Internet of Things device will correspond to an authorization information, and the authorization information of different environmental Internet of Things devices is independent and can be sent through the same message, that is, the core network device can send the authorization information of multiple environmental Internet of Things devices to the access network device through one message.

[0131] It should be noted that after receiving the authorization information, the access network device can provide services for the authorized environmental Internet of Things devices, or provide services for the specific business types authorized by the environmental Internet of Things devices.

[0132] Optionally, a specific implementation method for the core network device to obtain the authorization information of the terminal may include the following process:

[0133] Step S1: Receive third indication information sent by the access network device, where the third indication information includes at least one of the following: an indication that the at least one terminal is an environmental Internet of Things device, and identification information of the at least one terminal;

[0134] That is to say, the access network device needs to send the third indication information to the core network device. Optionally, the access network device should send the third indication information to the core network device before the access network device receives authorization information of at least one terminal from the core network device.

[0135] Optionally, in one implementation, the third indication information includes at least one of the following:

[0136] B11, an indication that the at least one terminal is an environmental IoT device;

[0137] It should be noted that this indication is used to indicate that the terminal is an environmental Internet of Things device. For example, if the third indication information received by the core network device includes this indication, the core network device can determine that the access network device is sending the third indication information for the environmental Internet of Things device.

[0138] B12. identification information of the at least one terminal;

[0139] For example, the identification information may be a 5GS temporary mobile subscription identifier (Temporary Mobile Subscription Identifier, TMSI), or the identification information may be a newly defined temporary identifier.

[0140] Step S2: Acquire at least one of the contract information and capability information of the at least one terminal according to the third indication information;

[0141] It should be noted that once the core network device determines which environmental Internet of Things device it is, it can obtain the contract information of the environmental Internet of Things device from the corresponding node or its own storage information. The contract information can indicate whether the environmental Internet of Things device is authorized, the authorized service type, etc.; it can also determine the capability information of the environmental Internet of Things device from the corresponding node or its own storage information. The capability information is used to indicate the device type of the environmental Internet of Things device and / or the service type that can be supported, etc.

[0142] It should be noted that the core network device can determine which terminals need to obtain contract information and / or capability information based on the third indication information, and then the core network device can obtain at least one item of contract information and capability information of part or all of the terminals determined at least one terminal; optionally, the core network device can obtain the contract information and / or capability information of only one terminal at a time, or it can obtain the contract information and / or capability information of multiple terminals at a time.

[0143] Step S3: Determine authorization information of the at least one terminal based on at least one of the contract information and capability information of the at least one terminal;

[0144] Optionally, the authorization information of each terminal is determined by its own corresponding contract information and / or capability information.

[0145] Optionally, the core network device can determine whether the environmental Internet of Things device is authorized and / or the service type authorized for the environmental Internet of Things device through the contract information and / or capability information.

[0146] Optionally, in one implementation, the method further includes:

[0147] receiving authorization change information of at least one terminal from the core network device;

[0148] If it is determined according to the authorization change information that the status of the second terminal in the at least one terminal has changed from authorized to deauthorized, stop providing services for the second terminal;

[0149] Optionally, the second terminal is one or more terminals among the at least one terminal whose status is changed from authorized to deauthorized.

[0150] This situation can be understood as follows: after the core network device notifies the access network device of the authorization information of the environmental Internet of Things device for the first time, in the subsequent process, if the contract information, capability information or other information that affects the authorization of the environmental Internet of Things device changes, the core network device can also change the authorization information of the environmental Internet of Things device, so that the access network device can adjust the communication strategy in time to avoid providing services to unauthorized environmental Internet of Things devices.

[0151] Optionally, the authorization change information includes at least one of the following:

[0152] C11. Second indication information, where the second indication information is used to indicate that one or more terminals among the at least one terminal are in an authorized or deauthorized state;

[0153] C12. a device type of the authorized terminal among the at least one terminal;

[0154] C13. The service type for which the at least one terminal is authorized.

[0155] It should be noted that the authorization change information can be understood as a type of authorization information, but it may be different from the authorization information sent previously. After receiving the authorization change information, the access network device can re-determine the authorization of the environmental Internet of Things device based on the difference from the previous authorization information. When the environmental Internet of Things device changes from authorization to deauthorization, the access network device stops providing services for the environmental Internet of Things device; when the specific service type of the environmental Internet of Things device changes from authorization to deauthorization, the access network device stops providing services for the specific service type of the environmental Internet of Things device.

[0156] It should be noted that the access network device mentioned in the embodiments of the present application refers to the device on the access network side, which can also be called a network device. For example, the access network device can be a base station.

[0157] The specific application of the embodiments of the present application is illustrated below with examples.

[0158] like Figure 3 As shown in the figure, the specific implementation process includes:

[0159] Step 31: The environmental Internet of Things device accesses the base station and sends an identifier of the environmental Internet of Things device to the base station;

[0160] For example, the identifier may be 5G-S-TMSI, or a newly defined temporary identifier.

[0161] Step 32: The base station sends an initial terminal message (Initial UE Message) to the core network device, where the initial terminal message includes third indication information;

[0162] Optionally, the base station should select AMF based on the identification of the environmental IoT device and send the initial terminal message to the core network device through AMF.

[0163] Step 33: The core network device sends authorization information to the base station;

[0164] Optionally, the core network device decides to accept access to the environmental Internet of Things device based on at least one of the contract information and capability information of the environmental Internet of Things device indicated by the third indication information. In this case, the authorization information may include at least one of the following:

[0165] First indication information of authorization of environmental IoT device;

[0166] Device type of ambient IoT devices;

[0167] Business types authorized for environmental IoT devices.

[0168] It should also be noted that the core network device can send an initial context establishment request message to the base station, and the initial context establishment request message includes authorization information of the ambient Internet of Things device.

[0169] Step 34: The base station sends a context establishment completion message to the core network device.

[0170] Step 35: If the environmental IoT device is authorized, the base station provides services for the environmental IoT device according to the corresponding authorization information;

[0171] For example, uplink data and downlink data transmission, uplink signaling and downlink signaling transmission, etc.

[0172] Step 36: The core network device decides to stop the service of the environmental IoT device and may send authorization change information to the base station;

[0173] Optionally, the authorization change information may be included in a terminal context modification request message, that is, the core network device sends a terminal context modification request message to the base station, and the terminal context modification request message carries the authorization change information.

[0174] Step 37: The base station receives the authorization change information and feeds back a context modification completion message to the core network device;

[0175] Furthermore, the base station stops providing services to unauthorized environmental IoT terminal devices based on the authorization change information.

[0176] It should be noted that at least one embodiment of the present application provides a method for authorization management of wireless air interface ambient IoT terminals, including processes such as indicating that the terminal is an ambient IoT device, core network device authorization, and authorization changes.
