DETAILED DESCRIPTION

To enable those skilled in the art to better understand the technical solutions of the embodiments of the present disclosure, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without making any creative efforts shall fall within the scope of protection of the present disclosure.

In the description of the present disclosure, unless otherwise specified, “/” means “or”, for example, A/B can mean A or B. “and/or” in this document means It simply describes an association relationship between related objects, indicating that three possible relationships exist. For example, "A and/or B" can mean: only A, only B, and both A and B. Furthermore, "at least one" refers to one or more, and "plurality" refers to two or more. The words "first" and "second" do not limit the number or order of execution, and the words "first" and "second" do not necessarily mean different.

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

In existing medium- and long-distance wireless power supply systems, power supply equipment is usually designed to serve only one or several specific devices, and power supply equipment in different scenarios and from different manufacturers cannot be used interchangeably, resulting in low system compatibility.

Furthermore, in medium- and long-distance wireless power supply systems, the terminals requiring power supply and the power supply scenarios are complex and diverse. For example, in some scenarios, terminals must be registered and authenticated before they can be powered, while in other scenarios, the terminals requiring power supply do not need to undergo registration and authentication.

In light of this, the present disclosure proposes a power supply method in which a first node determines a power supply service process; based on this process, the first node supplies power to a second node. This method, for complex and diverse terminal types and power supply scenarios, first determines the power supply service process, and then supplies power based on this process. This increases system flexibility, reduces unnecessary power supply service processes, and ultimately improves power supply efficiency and user experience.

For example, taking the first node as a power supply device and the second node as a terminal, as shown in Figure 1, a communication system provided by an embodiment of the present disclosure includes a terminal, a power supply device, and a base station. There can be one or more terminals, base stations, and power supply devices, and the number is not limited.

In some embodiments, the energy supply device provides wireless energy supply services to the terminal, and can send energy signals to the terminal device to supply energy to the terminal.

It should be noted that Figure 1 is only an exemplary framework diagram. The number of devices included in Figure 1 and the names of each device are not restricted. In addition to the devices shown in Figure 1, the communication system may also include other devices, such as core network devices.

The application scenarios of the embodiments of the present disclosure are not limited. The system architecture and business scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. It is known to those skilled in the art that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

The present disclosure provides an energy supply method. As shown in FIG2 , the method includes the following steps:

S101. The first node determines an energy supply service process.

S102: The first node supplies energy to the second node based on the energy supply service process.

For example, taking the first node as a power supply device and the second node as a terminal, the power supply node determines the power supply service process corresponding to the terminal and then supplies power to the terminal based on the power supply service process corresponding to the terminal. The power supply device may be a wireless power supply device.

In some embodiments, the energy supply service process is one of a first energy supply service process, a second energy supply service process, and a third energy supply service process. The first energy supply service process includes a registration/authentication process, a triggering process, an energy transmission process, and an energy release process. The second energy supply service process includes a triggering process, an energy transmission process, and an energy release process. The third energy supply service process includes an energy transmission process and an energy release process.

In some embodiments, for example, the first node is a power supply device and the second node is a terminal. The terminal performs a registration/authentication process. The registration/authentication process involves the terminal registering and authenticating with a server, core network, or power supply node to identify itself as a legitimate terminal. The server, core network, or power supply node maintains the terminal's registration information.

In some embodiments, for example, where the first node is a power supply device and the second node is a terminal, the registration/authentication process can bypass the core network, and the power supply device itself can complete the registration and authentication of the terminal. For example, the power supply device can directly connect to the terminal using a sidelink, Bluetooth, wireless fidelity (WI-FI), or other means to complete the terminal registration and authentication.

In some embodiments, as shown in FIG3 , the registration/authentication process includes:

The first node sends first indication information to the second node, where the first indication information is used to indicate an access mode;

The first node receives a first request message sent by the second node, where the first request message is used to request access;

The first node sends a first response message to the second node, where the first response message is used to indicate successful access;

The first node receives a second request message sent by the second node, where the second request message is used to request registration authentication at the first node, and the second request message includes identity authentication information of the second node;

The first node sends a second response message to the second node, where the second response message is used to indicate a registration authentication result at the first node.

Exemplarily, taking the first node as the energy supply device and the second node as the terminal as an example, the energy supply device first sends a broadcast message (i.e., the first indication information mentioned above) to the terminal to inform the terminal of the method for access authentication; then the terminal initiates an access request (i.e., the first request message mentioned above), and after receiving the first response message of the energy supply device, that is, after successful access, the terminal sends a second request message to the energy supply device for registration authentication, and the second request message includes identity authentication information; after the energy supply device authenticates and registers the terminal, it sends a second response message to the terminal, and the second response message includes the registration authentication result of the terminal on the energy supply device side.

In some embodiments, as shown in FIG4 , the registration/authentication process includes:

The first node sends a second indication message to the second node, where the second indication message is used to indicate an access and registration authentication method;

The first node receives a third request message sent by the second node, where the third request message is used to request access and registration authentication at the first node, and the third request message includes identity authentication information of the second node;

The first node sends a third response message to the second node, where the third response message is used to indicate a registration authentication result at the first node.

For example, the energy supply device sends a broadcast message (ie, the second instruction message mentioned above) to the terminal to inform the terminal to perform access and registration authentication. method; the terminal then initiates an access request to the energy supply device (i.e., the third request message mentioned above), and the access request carries the identity authentication information of the terminal; after the energy supply device receives the identity authentication information of the terminal, it authenticates and registers the terminal and sends a third response message to the terminal, and the third response message is used to indicate the registration authentication result of the terminal on the energy supply device side.

In some embodiments, taking the first node as a power supply device and the second node as a terminal as an example, the registration and authentication process may be a process in which a terminal with an independent subscriber identity module (SIM) card accesses the core network and performs registration and authentication, or a process in which multiple terminals belonging to the same terminal access the core network through a personal mobile device (e.g., a mobile phone) or other device as a proxy, including an access process performed on a random access channel (RACH) specified in the fifth generation mobile communication technology (5G) standard, an access process performed on a sidelink specified in the fifth generation mobile communication technology, an access and authentication process specified in the Institute of Electrical and Electronics Engineers (IEEE) 802.11 protocol, or a registration and authentication process performed by using a proxy device to relay and access the core network through other methods such as Bluetooth and wireless local area network (Wi-Fi).

In some embodiments, the registration/authentication process includes:

The first node receives a fourth request message sent by the second node, where the fourth request message is used to request access and registration authentication to the core network, and the fourth request message includes identity authentication information of the second node;

The first node sends a fourth response message to the second node, where the fourth response message is used to indicate a registration authentication result in the core network.

In some embodiments, the triggering process is mainly used to trigger the start of the energy transfer process, that is, the triggering process is used to trigger the first node to start energy transfer to the second node. The triggering process may include triggering the first node to start sending energy to the second node and triggering the second node to start receiving energy.

In some embodiments, the triggering process includes: the first node receiving a fifth request message sent by the second node, where the fifth request message is used to request to start energy transmission.

In some embodiments, the fifth request message includes a measurement reference signal, where the measurement reference signal is used to perform channel measurement and beam calibration on the first node.

In this way, after receiving the fifth request message sent by the second node, the first node can start transmitting energy to the second node, and at the same time use the measurement reference signal contained in the fifth request message to perform channel measurement and beam calibration, so that the first node can adjust the energy transmission strategy based on the channel measurement and beam calibration results to ensure the normal transmission of energy.

In some embodiments, the triggering process includes: the first node sending second indication information to the second node, where the second indication information is used to indicate the start of energy transmission.

In some embodiments, the second indication information includes a measurement reference signal, where the measurement reference signal is used to perform channel measurement and beam calibration on the first node.

In this way, after receiving the second indication information sent by the first node, the second node can start preparing to receive energy, and at the same time use the measurement reference signal contained in the second indication information to perform channel measurement and beam calibration, so that the channel measurement and beam calibration results can be informed to the first node to adjust the energy transmission strategy and ensure the normal transmission of energy.

Exemplarily, taking the first node as an energy supply device and the second node as a terminal, the terminal and the energy supply device perform a triggering process. This process includes triggering the energy supply device to start supplying energy to the terminal and triggering the terminal to start receiving energy. For example, when the terminal needs energy supply service, it sends energy supply request information (that is, the fifth request message mentioned above) to the energy supply device; for another example, the energy supply device may send downlink notification information (that is, the second indication information mentioned above) to inform the terminal to start energy supply.

In some embodiments, the energy transfer process mainly refers to the process from the first node to the second node starting to supply energy to the end of the energy supply. The energy transfer process can also have other names, such as the energy supply process.

In some embodiments, the energy transfer process includes: a first node sending an energy signal to a second node.

In some embodiments, the energy transfer process further includes periodic authentication and periodic measurement processes. Periodic authentication refers to periodically receiving identity authentication information sent by the second node. Periodic measurement refers to periodically receiving measurement results or reference signals sent by the second node, where the measurement results are determined based on the energy signal received by the second node.

The measurement results include energy receiving power, energy transmitting power and channel information. The reference signal carries the identity authentication information of the second node.

In this way, periodic authentication can help the first node regularly receive and verify the identity authentication information of the second node to ensure the security and reliability of network communications. Periodic measurement can help the first node perform channel measurement and beam calibration to achieve energy-efficient transmission.

In some embodiments, after the energy transfer process ends, the first node and the second node may further perform an energy release process. The energy release process primarily refers to the process of terminating energy transfer, including the first node notifying the second node of the termination of energy transfer or the second node notifying the first node of the termination of energy transfer. The energy release process may also be referred to by other names, such as a release process, which is not limited in this disclosure.

In some embodiments, the energy release process includes:

The first node sends third indication information to the second node, where the third indication information is used to instruct to stop supplying energy to the second node; or,

The first node receives fourth indication information sent by the second node, where the fourth indication information is used to instruct to stop supplying energy to the second node; or,

If the first node does not receive a signal sent by the second node for longer than a preset time, it stops supplying energy to the second node. The signal includes a reference signal, a measurement result, and identity authentication information.

For example, taking the first node as the energy supply device and the second node as the terminal, when the terminal expects to stop supplying energy, it sends an energy supply termination request signal (i.e., the fourth indication information mentioned above) to inform the energy supply device to stop supplying energy, or, due to deterioration of channel conditions or other reasons, the energy supply device sends a downlink signal (i.e., the third indication information mentioned above) to inform the terminal to terminate energy supply. In some cases, the process can also be that during the energy supply process, the terminal unilaterally stops sending signals (the signal includes an uplink reference signal, reported measurement results and identity authentication information), and the energy supply device stops supplying energy to the terminal when it does not receive the signal within a preset time.

In some embodiments, the first node determines the energy supply service process, including: the first node determines the energy supply service process according to the energy supply service scenario.

In some embodiments, the first node determines the energy supply service process, including: the first node determines the energy supply service process according to the type of the second node.

In some embodiments, the uplink signal (e.g., the first request message, the second request message, the third request message, the fourth request message, and the fifth request message) sent by the second node to the first node includes type information of the second node, and the first node determines the type of the second node based on the uplink signal. In this way, determining the type of the second node based on the uplink signal avoids the need to send additional information indicating the type of the second node, thus saving resources. It also facilitates subsequent energy supply by the first node to the second node based on the type of the second node, thereby improving energy supply efficiency.

In some embodiments, the type of the second node is determined according to at least one of the following:

When receiving a message sent by the second node that is a first type message, determining that the type of the second node is the first type; the first type message includes at least one of the following: a first request message, a third request message, and a fourth request message. The first request message is used to request access, the third request message is used to request access and registration authentication at the first node, and the fourth request message is used to request access and registration authentication to the core network;

When the first type message sent by the second node is not received and a fifth request message sent by the second node is received, determining that the type of the second node is the second type. The fifth request message is used to request to start energy transmission;

When the first type message and the fifth request message sent by the second node are not received and a sixth request message sent by the second node is received, it is determined that the type of the second node is the third type. The sixth request message includes a binary on-and-off keying (OOK) signal.

In some embodiments, determining the energy supply service process according to the type of the second node includes:

In a case where the type of the second node is the first type, determining that the energy supply service process corresponding to the second node is the first energy supply service process;

When the type of the second node is the second type, determining that the energy supply service process corresponding to the second node is the second energy supply service process;

When the type of the second node is the third type, it is determined that the energy supply service process corresponding to the second node is the third energy supply service process.

Exemplarily, the energy supply service process corresponding to the second node is the second energy supply service process. Taking the first node as the energy supply device and the second node as the terminal as an example, the energy supply service process based on which the energy supply device supplies energy to the terminal includes a triggering process, an energy transmission process, and an energy release process, i.e., no registration/authentication process is required.

For example, in some special scenarios such as homes, factories, hospitals, etc., when there is a high probability that there are no illegal terminals, the terminals do not need to go through the registration/authentication process; or, when wireless power is supplied to some IoT terminals that do not have the registration/authentication capability, there is no need to go through the registration/authentication process.

For example, in some cases, when some terminals can only send a few preset waveforms or simple OOK signals, there is no need to perform a registration/authentication process, and the energy supply service process based on which the energy supply equipment supplies energy to these terminals includes a triggering process, an energy transmission process, and an energy release process. At this time, the terminal can use several specific waveforms or several specific OOK sequences to represent energy supply request signals (for example, the fifth request message and the second indication information mentioned above), different measurement results, and energy supply termination request signals (for example, the third indication information and the fourth indication information mentioned above).

Exemplarily, taking the first node as the energy supply device and the second node as the terminal as an example, the energy supply service process based on which the energy supply device supplies energy to the terminal is the third energy supply service process, that is, it includes the energy transmission process and the energy release process, that is, there is no need to perform a registration/authentication process or a trigger process. For example, in some cases (such as when the terminal is out of power), when the terminal is unable to send an energy request signal (for example, the fifth request message mentioned above) to the wireless energy supply device, the terminal is unable to complete the trigger process, and the energy supply service process based on which the energy supply device supplies energy to the terminal is the third energy supply service process. For another example, for some special terminals such as IoT sensors, the terminal itself does not have energy reserves and needs to rely on the energy provided by the energy supply device to work. At this time, the energy supply service process based on which the energy supply device supplies energy to the terminal does not need to include a trigger process.

In some embodiments, when the energy supply service process corresponding to the second node is the third energy supply service process, the first node periodically sends an energy signal to the second node until receiving a response message from the second node, and starts to supply energy to the second node; the response information includes beam calibration information of the energy signal.

Exemplarily, taking the first node as the energy supply device and the second node as the terminal as an example, FIG5 shows a schematic diagram of an energy signal transmission process. The energy supply device transmits the energy signal in a beam scanning manner, and uses different beams to transmit the energy signal at different times. After the terminal receives the energy signal in a certain direction, it can obtain the index information of the energy signal and carry the index information in the response signal for reporting, thereby helping the energy supply device to perform beam calibration. If the terminal reports a certain index information i, it means that the i-th beam has been activated, and the i-th beam is sent each time in the subsequent beam scanning process, and other beams are sent in sequence. As shown in FIG6, when terminal 1 reports index 1, the beam of energy signal 1 is sent in each scan, and when terminal 1 sends a power supply termination request signal, beam 1 is released.

Based on this, for complex and diverse terminal types and energy supply scenarios, the energy supply service process is first determined, and then energy is supplied based on the energy supply service process, which increases the flexibility of the system, thereby improving energy supply efficiency and improving user experience.

The above mainly introduces the solution of the embodiment of the present disclosure from the perspective of method. The following also shows an energy supply device, which is used to perform the energy supply method in any of the above embodiments and possible implementations thereof.
