FIG1 is a flow chart of a communication method according to an exemplary embodiment. As shown in FIG1 , the method is applied in UE (User Equipment), and the method includes the following steps.

In step S101, a registration request is sent to a network device;

For example, this embodiment is applied to a UE, which is an IoT device that can communicate with a mobile network without a traditional power supply, avoiding manual intervention for charging or replacing batteries. The UE can use energy obtained from radio waves or any other form of energy that can be obtained under specific usage conditions, and convert the energy into power for the UE. For example, the radio waves may come from a wireless network entity or other UE, and other forms of energy may be solar energy, light energy, mechanical kinetic energy, thermal energy, pressure, etc. The UE can be applied to the following multiple scenarios:

(1) IWSN (Industrial Wireless Sensor Network)

IWSN has been widely used in physical manufacturing scenarios, which can provide energy collection for IWSN to enable UE to complete more application functions. In IWSN applications, due to the harsh working environment, high/low temperature, moving or rotating parts, high vibration conditions, humidity and other dangerous conditions, the UE is required to be maintenance-free, battery-free, ultra-low power consumption and long service life.

(2) Smart logistics and smart warehousing

In the case of logistics and warehousing, a large amount of goods need to be frequently transferred, stored, loaded and unloaded, and stocked in logistics stations or warehouses (tens of thousands of square meters). The Internet of Things based on ambient power, with its extremely low cost, small size, maintenance-free, durable, and long life, can realize intelligent logistics and intelligent warehousing.

(3) Smart Home Network

IoT that supports ambient power can be applied to home appliance management, wearable devices, and environmental (temperature, humidity, etc.) monitoring, etc. due to its ultra-low cost, very small form factor, washable, flexible/foldable form factor, and very long service life.

(4) Smart Agriculture

IoT that supports ambient power is beneficial to smart agriculture. For example, an ambient power-enabled UE powered by solar energy can be used to monitor soil moisture, soil fertility, temperature, wind speed, plant growth, etc. In addition, the device can also be used to control agricultural facilities such as irrigation systems. For smart agriculture, it is necessary to widely deploy ambient power-enabled UEs in farms with sufficient density. Normally, communication systems will not have conventional power supplies, and ambient power-enabled UEs cannot use conventional batteries due to their working environment and long life requirements. Therefore, energy obtained from solar energy can be a solution to promote the promotion and application of communication systems and equipment.

In the above application scenarios, the power of UE mainly comes from the energy in the environment, but the energy in the environment is affected by multiple factors and is unstable. In some application scenarios, the energy in the environment may be low, resulting in the inability to continuously provide power to the UE. For example, in the above-mentioned smart agriculture application scenario, the UE that provides power by absorbing solar energy cannot absorb solar energy from the environment in rainy weather, causing the UE to lose power and be unable to communicate with the mobile network. The mobile network end cannot realize the on-demand communication of the UE according to the current communication availability of the UE. Therefore, a communication method is proposed in this embodiment to support environmental Internet of Things communication in the mobile network.

For example, FIG2 is a schematic diagram of a wireless network system architecture of an environmental Internet of Things according to an exemplary embodiment. As shown in FIG2, the system architecture includes a UE and a network device. The network device may include: RAN (Radio Access Network) equipment, UPF (User Plane Function) network element, AMF (Access and Mobility Management Function) network element, SMF (Session Management Function) network element, UDM (Unified Data Management) network element, NEF (Network Exposure Function) network element, AF (Access Facilities). The UE in this embodiment is connected to the network device through the above-mentioned system architecture, thereby realizing wireless communication between the UE and the network device. When the UE establishes communication interaction with the network device for the first time, the UE needs to send a registration request to the network device for registration, and the network device determines whether to authorize the communication interaction with the UE according to the registration request.

Optionally, the registration request includes registration type information, user identification information and security parameter information.

By way of example, in this embodiment, when the UE sends a registration request to the network device, the registration request includes registration type information, user identification information and security parameter information, so that the network device can judge the registration request of the UE based on the relevant information in the registration request to determine whether the UE can be authorized for registration. By way of example, the network device can determine whether the UE has a legal identity based on the user identification information, determine whether to establish a corresponding type of communication service with the UE based on the registration type information, and determine whether the communication interaction with the UE is secure based on the security parameter information, thereby determining whether to authorize the communication interaction with the UE based on the relevant information in the registration request.

Optionally, the user identification information includes at least one of a subscriber implicit identity SUCI, a global unique temporary user equipment identity GUTI or a permanent equipment identifier PEI.

For example, in this embodiment, the user identification information corresponding to the UE may include at least one of a subscribed user implicit identification SUCI, a globally unique temporary user equipment identification GUTI, or a permanent equipment identifier PEI. The network device can determine the unique identity of the UE through the above user identification information, and determine whether to authorize communication interaction with the UE based on the identity.

In step S102, in response to the authorization information fed back by the network device according to the registration request, signaling information is sent to the network device, where the signaling information includes the communication state mode of the user equipment;

For example, in this embodiment, the network device determines the communication authorization of the UE through a registration request, and when the UE is authorized to establish a communication interaction, the authorization information is fed back to the UE, so as to feed back the authorization success to the UE according to the authorization information. After receiving the authorization information, the UE sends signaling information to the network device, and the signaling information is used to indicate the communication state mode of the UE. It is worth mentioning that in this embodiment, the UE is an Internet of Things device that provides power by obtaining energy from the environment. Due to the influence of the instability of environmental energy, the communication state mode of the UE fluctuates. Therefore, the UE needs to report the current communication state mode of the UE to the mobile network, so that the network device adjusts the communication mode with the UE according to the communication state mode of the UE, thereby realizing on-demand communication and avoiding unnecessary communication overhead. In this embodiment, after the UE establishes a communication connection with the network device for the first time, the communication state mode of the UE needs to be sent to the network device, and the network device performs different modes of wireless communication with the UE according to different communication state modes. For example, based on the communication state mode sent to the network device during registration, when the communication state mode changes, the UE sends the current communication state mode of the UE to the network device.

Optionally, the communication status mode includes: a normal communication mode, a receiving communication mode or a sleep communication mode.

For example, in normal communication mode, the UE can send signaling and data to the network device, and can receive signaling and data sent by the network device. For example, when the UE can obtain sufficient energy from the environment, the communication state mode of the UE may be normal communication mode. For another example, in receiving communication mode, the UE can receive signaling and data sent by the network device, but the UE cannot send signaling and data to the network device. For example: when the UE obtains a certain amount of energy from the environment, the communication state mode of the UE may be receiving communication mode. For another example, in sleep communication mode, the UE cannot send signaling and data to the network device, nor can it receive signaling and data sent by the network device. For example: when the UE cannot obtain sufficient energy from the environment to support the UE in normal communication mode and receiving communication mode, the communication state mode of the UE may be sleep communication mode.

In step S103, signaling response information fed back by the network device according to the signaling information is received.

By way of example, in this embodiment, after receiving the signaling information sent by the UE, the network device determines the communication mode with the UE through the signaling information, and generates a signaling response message according to the signaling information. The network device sends the signaling response message to the UE. The signaling response message is used to indicate to the UE that the network device confirms receipt of the communication state mode of the UE, and establishes communication with the UE according to the communication state mode. The UE communicates with the network device according to the corresponding communication state mode of the signaling response information. By way of example, after receiving the signaling information of the UE, the network device stores the communication state mode of the UE, and after sending the signaling response message, processes the communication with the UE according to the communication state mode.

In the above manner, the UE reports the communication state mode to the network device according to the signaling information, and the network device feeds back the corresponding signaling response information to the UE according to the communication state mode, and establishes communication with the UE based on the communication state mode. Thus, the UE reports its communication availability to the network device, realizes the on-demand communication of the UE, and supports the ambient IoT communication in the mobile network.

Figure 3 is a flow chart of a communication method according to an exemplary embodiment. As shown in Figure 3, the method is applied in UE (User Equipment), and the method includes the following steps.

In one implementation, the network device includes: a RAN device and an AMF network element, and the above step of sending a registration request to the network device includes:

In step S201, a registration request is sent to an access and mobility management function AMF network element through a radio access network RAN device.

For example, the UE in this embodiment is connected to the mobile network through the above system architecture, wherein the UE can be connected to the AMF network element through the N1 interface, or connected to the RAN device through the Uu interface, thereby realizing wireless communication between the UE and the mobile network. When the UE establishes communication interaction with the AMF network element for the first time, the UE needs to send a registration request to the AMF network element through the RAN device for registration, and the AMF network element determines whether to authorize the communication interaction with the UE based on the registration request.

In another embodiment, the above steps, in response to the authorization information fed back by the network device according to the registration request, send signaling information to the network device, including:

In step S202, in response to the authorization information fed back by the AMF network element according to the registration request, signaling information is sent to the AMF network element through the RAN device, and the signaling information includes the communication status mode of the user equipment.

For example, in this embodiment, the AMF network element determines the communication authorization of the UE through a registration request, and when the UE is authorized to establish a communication interaction, the authorization information is fed back to the UE, so as to feed back the authorization success to the UE according to the authorization information. After receiving the authorization information, the UE sends signaling information to the AMF network element through the RAN device, and the signaling information is used to indicate the communication state mode of the UE. It is worth mentioning that in this embodiment, the UE is an IoT device that provides power by obtaining energy from the environment. Due to the influence of the instability of environmental energy, the communication state mode of the UE fluctuates. Therefore, the UE needs to report the current UE communication state mode to the mobile network, so that the AMF network element adjusts the communication mode with the UE according to the communication state mode of the UE, thereby realizing on-demand communication and avoiding unnecessary communication overhead. In this embodiment, after the UE establishes a communication connection with the AMF network element for the first time, the communication state mode of the UE needs to be sent to the AMF network element, and the AMF network element performs different modes of wireless communication with the UE according to different communication state modes. For example, based on the communication state mode sent to the AMF network element during registration, when the communication state mode changes, the UE sends the current communication state mode of the UE to the AMF network element through the RAN device.

In another embodiment, the above step of receiving signaling response information fed back by the network device according to the signaling information includes:

In step S203, signaling response information fed back by the AMF network element based on the signaling information is received through the RAN device.

For example, in this embodiment, after receiving the signaling information sent by the UE, the AMF network element determines the communication mode with the UE through the signaling information, and generates a signaling response message according to the signaling information. The AMF network element sends the signaling response message to the UE through the RAN device. Among them, the signaling response message is used to indicate to the UE that the AMF network element confirms the receipt of the communication status mode of the UE, and establishes communication with the UE according to the communication status mode. The UE communicates with the AMF network element according to the corresponding communication status mode of the signaling response information. For example, after the RAN device receives the signaling information of the UE, it stores the communication status mode of the UE, and after receiving the signaling response information, it processes the communication with the UE according to the communication status mode; after the AMF network element receives the signaling information of the UE, it stores the communication status mode of the UE, and after sending the signaling response information, it processes the communication with the UE according to the communication status mode.

Through the above method, the UE reports the communication status mode to the AMF network element according to the signaling information, and the AMF network element feeds back the corresponding signaling response information to the UE according to the communication status mode, and establishes communication with the UE based on the communication status mode. In this way, the UE reports its communication availability to the AMF network element, realizes the on-demand communication of the UE, and supports the environmental Internet of Things communication in the mobile network.

FIG. 4 is a flow chart of a communication method according to an exemplary embodiment. As shown in FIG. 4 , the method is applied in a UE, and the method includes the following steps.

In step S301, a registration request is sent to the AMF network element through the RAN device.

For example, the method of sending the registration request in this embodiment is the same as that in the above step S201, and can refer to the above step S201, which will not be repeated here.

In one implementation, the above-mentioned step of sending signaling information to the AMF network element through the RAN device in response to the authorization information fed back by the AMF network element according to the registration request, wherein the signaling information includes the communication state mode of the user equipment, comprises:

In step S302, in response to the authorization information fed back by the AMF network element according to the registration request, signaling information is sent to the AMF network element through the non-access layer NAS of the RAN device, and the signaling information includes the communication status mode of the user equipment.

For example, in this embodiment, a communication connection is established between the UE and the RAN device, and the signaling information is sent to the RAN device through the NAS (Non-Access Stratum) of the RAN device, and then the signaling information is sent to the AMF network element through the NAS between the RAN device and the AMF network element. Among them, the signaling information is NAS information, which is clear to the RAN device. The RAN device does not need to determine the content in the NAS information and directly sends the NAS information to the AMF network element.

In another implementation, the above steps receive, through the RAN device, signaling response information fed back by the AMF network element according to the signaling information, including:

In step S303, the signaling response information fed back by the AMF network element through the NAS of the RAN device is received, and the signaling response information is NAS information.

For example, in this implementation, the way in which the AMF network element generates signaling response information according to the signaling information is the same as in the above step S203, and the above step S203 can be referred to and will not be repeated. After the AMF network element generates the signaling response information according to the signaling information, the signaling response information is sent to the RAN device through the NAS of the RAN device, and the RAN device feeds back the signaling response information to the UE through the NAS. Among them, the role of the signaling response information is the same as in the above step S203, and the above step S203 can be referred to and will not be repeated.

In the above manner, the UE reports the communication status mode to the AMF network element through the NAS of the RAN device according to the signaling information, and the AMF network element feeds back the corresponding signaling response information to the UE according to the communication status mode, and establishes communication with the UE based on the communication status mode. In this way, the UE reports its communication availability to the AMF network element, realizes the on-demand communication of the UE, and supports the environmental Internet of Things communication in the mobile network.

FIG. 5 is a flow chart of a communication method according to an exemplary embodiment. As shown in FIG. 5 , the method is applied in a UE, and the method includes the following steps.

In step S401, a registration request is sent to the AMF network element through the RAN device.

In step S402, in response to the authorization information fed back by the AMF network element according to the registration request, signaling information is sent to RNA through the access layer AS of the RAN device, so as to send a signaling message to the AMF network element through the RAN device according to the N2 interface, and the signaling information includes the communication status mode of the user equipment.

For example, in this embodiment, a communication connection is established between the UE and the RAN device, and the signaling information is sent to the RAN device through the AS (Access Stratum) of the RAN device. The RAN device parses the signaling information, determines the corresponding AMF network element, and sends the signaling information to the AMF network element through the N2 interface between the RAN device and the AMF network element.

In another embodiment, the above steps receive, through the RAN device, signaling response information fed back by the AMF network element according to the signaling information, including:

In step S403, signaling response information fed back by the RAN device through the AS is received, where the signaling response information is sent by the AMF network element to the RAN device through the N2 interface.

For example, in this embodiment, the way in which the AMF network element generates signaling response information according to the signaling information is the same as in the above step S203, and the above step S203 can be referred to and no further description is given. In this embodiment, after the AMF network element generates signaling response information according to the signaling information, the signaling response information is sent to the RAN device through the N2 interface between the RAN device, and the RAN device parses the signaling response information to determine the corresponding UE, and then sends the signaling response information to the UE through the AS, wherein the role of the signaling response information is the same as in the above step S203, and the above step S203 can be referred to and no further description is given.

In the above manner, the UE reports the communication status mode through the AS of the RAN device according to the signaling information, and reports the communication status mode to the AMF network element through the N2 interface between the RAN device and the AMF network element. The AMF network element feeds back the corresponding signaling response information to the UE according to the communication status mode, and establishes communication with the UE based on the communication status mode. Thus, the UE reports its communication availability to the AMF network element, realizes the on-demand communication of the UE, and supports the environmental Internet of Things communication in the mobile network.

FIG. 6 is a flow chart showing a communication method according to an exemplary embodiment. As shown in FIG. 6 , the method is applied in a radio access network RAN device, and the method includes the following steps.

In step S501, in response to a registration request sent by a user equipment, a registration request is sent to an AMF network element.

For example, the definition of the registration request in this embodiment is the same as that in the above step S201, and can refer to the above step S201, which will not be repeated here.

For example, the definition of the user identification information in this embodiment is the same as that in the above step S201, and can refer to the above step S201, which will not be repeated here.

In step S502, in response to the signaling information sent by the user equipment when receiving the authorization information fed back by the AMF network element according to the registration request, the signaling information is sent to the AMF network element, where the signaling information includes the communication state mode of the user equipment;

For example, the method of sending signaling information in this embodiment is the same as that in the above step S202, and can refer to the above step S202, which will not be repeated here.

For example, the definition of the communication status mode in this embodiment is the same as that in the above step S202, and can refer to the above step S202, which will not be repeated here.

For example, the method of sending the signaling response information in this embodiment is the same as that in the above step S203, and can refer to the above step S203, which will not be repeated here.

Optionally, in one implementation, after the above step S503, the communication method further includes:

In response to the received signaling response information, communication data between the RAN device and the user equipment is transmitted.

For example, in this embodiment, after receiving the signaling response information, the RAN device instructs the RAN device to perform communication interaction with the UE according to the signaling response information.

Optionally, in another implementation manner, the above step of transmitting communication data between the RAN device and the user equipment in response to the received signaling response information includes:

Determining a target communication state mode of the user equipment according to the signaling response information;

When the target communication state mode is a normal communication mode, receiving and/or sending communication data with the user equipment;

When the target communication state mode is a receiving communication mode, sending communication data with the user equipment;

When the target communication state mode is the sleep communication mode, receiving and/or sending communication data with the user equipment is prohibited.

For example, in this embodiment, after the RAN device receives the signaling response information from the AMF network element, it determines the communication state mode of the UE through the signaling response information, and determines the communication mode between the RAN device and the UE according to the communication state mode, and processes the communication data with the UE according to the communication mode. For example, when the communication state mode of the UE is the normal communication mode, the RAN device uses the UE as a normal communication device to receive or send signaling and data; when the communication state mode of the UE is the receiving communication mode, the RAN device uses the UE as a receiving device and only sends signaling and data to the UE; when the communication state mode of the UE is the sleep communication mode, the communication between the RAN device and the UE stops, and the RAN device cannot send or receive signaling and data from the UE.

In the above manner, the RAN device is used to send the communication state mode of the UE to the AMF network element, and the RAN device enables the AMF network element to feedback the corresponding signaling response information to the UE according to the communication state mode, and establish communication with the UE based on the communication state mode. In this way, the UE reports its communication availability to the AMF network element, realizes the on-demand communication of the UE, and supports the environmental Internet of Things communication in the mobile network.

For example, the method of sending signaling response information through AS in this embodiment is the same as that in the above step S402, and can refer to the above step S402, which will not be repeated. It is worth mentioning that, under normal circumstances, after the RAN device receives the signaling response information sent by the AMF network element, it needs to feedback the communication information to the AMF network element, and the AMF network element feedbacks the confirmation character to the RAN device through the communication information. After receiving the confirmation character, the RAN device feedbacks the signaling response information through AS. In this embodiment, in order to improve the transmission efficiency of communication data, after the RAN device receives the signaling response information, it does not need to wait for the confirmation character from the AMF network element, and directly sends the signaling response information to the UE.

Optionally, in another implementation, the above step S705 includes:

For example, in this embodiment, after the RAN device receives the signaling response information sent by the AMF network element, it needs to feedback communication information to the AMF network element. The communication information is used to feedback to the AMF network element that the RAN device has received the signaling response information. After the AMF network element receives the communication information, it controls the timing of the RAN device sending the signaling response information through ACK (Acknowledge character). When the AMF network element determines that the signaling response information needs to be sent to the UE, it generates an ACK according to the communication information and sends the ACK to the RAN device. The RAN device responds to the ACK and sends the signaling response information to the UE through the AS.

Optionally, in another implementation, the above steps transmit communication data between the AMF network element and/or other core network nodes and the user equipment according to the signaling response information, including:

By way of example, in this embodiment, the AMF network element generates the signaling response information corresponding to the UE through the above steps, and determines the communication mode between the AMF network element and other core network nodes and the UE according to the signaling response information, so that the AMF network element and other core network element nodes process the communication with the UE according to the communication mode. By way of example, when the communication mode is determined to be a normal communication mode according to the signaling response information, the UE is used as a normal communication device, and the AMF network element and other core network nodes can send or receive signaling and data to the UE; when the communication mode is determined to be a receive-only communication mode according to the signaling response information, the UE is used as a receiving device, and the AMF network element and other core network nodes can only send signaling and data to the UE; when the communication mode is determined to be a dormant communication mode according to the signaling response information, the communication with the UE is stopped, and the AMF network element and other core network nodes cannot send or receive signaling and data to the UE.
