[0038] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0039] Reference Figure 1 The diagram illustrates a step flowchart of a method for communication between terminal devices according to an embodiment of the present invention, which can be applied to a second terminal device.

[0040] The second terminal device is a terminal device based on a long-distance radio wide area network, specifically a terminal device based on a device-to-device mode in a long-distance radio wide area network.

[0041] Specifically, it may include the following steps:

[0042] Step 101: The second terminal device receives any one of one or more wake-up frames sent by the first terminal device; wherein each wake-up frame carries at least a set of addresses of the first receiving terminal device.

[0043] The first terminal device is a terminal device based on a long-distance radio wide area network. Specifically, it can be a terminal device based on a device-to-device mode in a long-distance radio wide area network. That is, the first terminal device and the second terminal device communicate using a device-to-device mode in a long-distance radio wide area network.

[0044] like Figure 2a and Figure 2b The wake-up frame may include a preamble and a data portion. The first receiving device address set may be included in the data portion of the wake-up frame. The first receiving device address set may include the device addresses of one or more terminal devices. The device addresses of the one or more terminal devices are the device addresses of the terminal devices to which the first terminal device needs to send messages, and they can be set by the first terminal device according to actual needs.

[0045] When a first terminal device needs to send a message to one or more terminal devices, the first terminal device can first send a wake-up frame. It can send one wake-up frame or multiple wake-up frames, so that multiple wake-up frames can be supported in the device-to-device mode in long-distance radio wide area network.

[0046] like Figure 2a When a wake-up frame is sent to the first terminal device, the processing method is relatively simple and the wake-up rate is high. However, the amount of preamble data is very large, which leads to a large power consumption of the terminal device receiving the wake-up frame.

[0047] like Figure 2b In the case of sending multiple wake-up frames to the first terminal device, the amount of preamble data is relatively small. As long as the terminal device receives any one of the wake-up frames, it can enter a sleep state, reducing power consumption. However, the processing is more complex and the wake-up rate is slightly lower.

[0048] After receiving the wake-up frame sent by the first terminal device, the received wake-up frame can be the only wake-up frame sent by the first terminal device, or it can be any one of the multiple wake-up frames sent by the first terminal device.

[0049] Step 102: When the second terminal device detects that the device address of the second terminal device is included in the first set of receiving terminal device addresses, the second terminal device receives one or more ordinary frames sent by the first terminal device.

[0050] The ordinary frame can include a preamble part and a data part. The preamble part of the wake-up frame can be different from the preamble part of the ordinary frame, so that multiple preambles can be supported in the device-to-device mode of long-distance radio wide area network.

[0051] In one example, the data portion of a normal frame may contain a second set of receiving device addresses. This second set of receiving device addresses may contain the device addresses of one or more terminal devices. These device addresses are the device addresses of the terminal devices to which the first terminal device needs to send messages. The device addresses to which the first terminal device needs to send messages can be set by the first terminal device according to its actual needs. Of course, the data portion of a normal frame also includes a content portion, such as parameter setting commands.

[0052] After reading the first set of receiving device addresses from the data portion of the wake-up frame, the second terminal device can determine whether its own device address is included in the first set of receiving device addresses. If there is only one device address in the first set of receiving device addresses, it can directly determine whether that device address is the same as its own device address.

[0053] If the device address of the first terminal device is not included in the set of device addresses of the first receiving end, it means that the first terminal device does not need to send a message to the second terminal device. In this case, when the first terminal device continues to send ordinary frames, the second terminal device can directly ignore them and not receive them.

[0054] If the device address of the first terminal device is included in the first receiving device address set, it indicates that the first terminal device needs to send a message to the second terminal device. In this case, while the first terminal device continues to send ordinary frames, the second terminal device can further receive subsequent ordinary frames from the first terminal device.

[0055] Specifically, such as Figure 2a and Figure 2b When the communication packet data volume is small, the first terminal device can send a normal frame. When the communication packet data volume is large, it can also send multiple normal frames, so that multiple normal frames can be supported in the device-to-device mode in long-distance radio wide area network.

[0056] In fact, by setting the first set of receiving device addresses, after the first terminal device sends a message, other terminal devices can know whether it is a terminal device that needs to receive the message. If it is not a terminal device that needs to receive the message, it is ignored; if it is a terminal device that needs to receive the message, it can receive the message. This allows a message to be sent to multiple terminal devices. For example, if terminal device A wants to send a parameter setting message to 100 terminal devices, it used to need to send 100 messages one by one to each terminal device. Now, it only needs to send one message to receive it from all 100 terminal devices.

[0057] In this embodiment of the invention, the second terminal device receives one or more wake-up frames sent by the first terminal device. Each wake-up frame carries at least a first set of receiving device addresses. When the device address of the second terminal device is detected in the first set of receiving device addresses, the second terminal device receives one or more ordinary frames sent by the first terminal device. This enables the sending device to communicate with multiple receiving devices through one message, supports multiple receiving devices, multiple wake-up frames, and multiple ordinary frames, improves communication efficiency, and reduces resource consumption.

[0058] Reference Figure 3 The diagram illustrates a flowchart of another method for communication between terminal devices according to an embodiment of the present invention, which can be applied to a second terminal device.

[0059] Specifically, it may include the following steps:

[0060] Step 301: The second terminal device receives any one of one or more wake-up frames sent by the first terminal device; wherein each wake-up frame carries at least the first receiving device address set and the first next frame time interval information.

[0061] The first next frame time interval information can be included in the data part of the wake-up frame. This first next frame time interval information can be used to determine the time information for receiving the first normal frame after the wake-up frame. That is, the first next frame time interval information can be the time interval information between the wake-up frame and the normal frame. For example, the first next frame time interval can be the time interval between the time when the first terminal device sends the wake-up frame and the time interval between the time when the first terminal device sends the first normal frame.

[0062] It should be noted that when the first terminal device sends multiple wake-up frames to the second terminal device, each wake-up frame carries the first next frame time interval information, and the first next frame time interval information carried by each wake-up frame is different. For example, the first wake-up frame writes 1.08 seconds, the second wake-up frame writes 1.03 seconds, and so on. When the first terminal device sends a single wake-up frame to the second terminal device, the wake-up frame may or may not carry the first next frame time interval information, and may directly use the pre-agreed next frame time interval information.

[0063] When a first terminal device needs to send a message to one or more terminal devices, the first terminal device can first send a wake-up frame. It can send one wake-up frame or multiple wake-up frames, so that multiple wake-up frames can be supported in the device-to-device mode in long-distance radio wide area network.

[0064] After receiving the wake-up frame sent by the first terminal device, the received wake-up frame can be the only wake-up frame sent by the first terminal device, or it can be any one of the multiple wake-up frames sent by the first terminal device.

[0065] Step 302: When the second terminal device detects that the first receiving device address set contains the device address of the second terminal device, it receives the first normal frame sent by the first terminal device according to the first next frame time interval information carried in the received wake-up frame. After reading the first receiving device address set from the data portion of the wake-up frame, the second terminal device can determine whether its own device address is included in the first receiving device address set. If only one device address exists in the first receiving device address set, it can directly determine whether that device address is the same as its own device address.

[0066] If the device address of the first terminal device is not included in the set of device addresses of the first receiving end, it means that the first terminal device does not need to send a message to the second terminal device. In this case, when the first terminal device continues to send ordinary frames, the second terminal device can directly ignore them and not receive them.

[0067] If its own device address is included in the first receiving end device address set, it indicates that the first terminal device needs to send a message to the second terminal device. The second terminal device can further obtain the first next frame time interval information from the data part of the wake-up frame.

[0068] Since the first next frame time interval information indicates the time interval for sending the first normal frame, the second terminal device can receive the first normal frame sent by the first terminal device according to the first next frame time interval information. During the interval time corresponding to the first next frame time interval information, the second terminal device can perform operations such as sleep mode to save energy.

[0069] It should be noted that if the first terminal device sends only one normal frame, then the first normal frame referred to here is that normal frame, and there are no subsequent different frames. If the first terminal device sends multiple normal frames, then there will be other normal frames after the first normal frame.

[0070] Reference Figure 4 The diagram illustrates a flowchart of another method for communication between terminal devices according to an embodiment of the present invention, which can be applied to a second terminal device.

[0071] Specifically, it may include the following steps:

[0072] Step 401: The second terminal device receives any one of one or more wake-up frames sent by the first terminal device; wherein each wake-up frame carries at least the first receiving device address set and the first next frame time interval information.

[0073] Step 402: When the second terminal device detects that the device address of the second terminal device is included in the first receiving terminal device address set, the second terminal device receives the first normal frame sent by the first terminal device according to the first next frame time interval information carried in the received wake-up frame.

[0074] Step 403: When the second terminal device receives the Nth ordinary frame sent by the first terminal device, it receives the (N+1)th ordinary frame sent by the first terminal device according to the second next frame time interval information carried in the Nth ordinary frame; wherein, when there are multiple ordinary frames, the Nth ordinary frame carries the second next frame time interval information, and N is a positive integer greater than or equal to 1.

[0075] In the case of multiple normal frames, all normal frames except the last normal frame (including the first normal frame) can carry the second next frame time interval information. The second next frame time interval information can be included in the data part of the normal frame and can be used to determine the time to receive the next normal frame.

[0076] Specifically, the second next frame time interval information can be the time interval information between two adjacent normal frames. It can be set to be the same as the first next frame time interval information. For example, the second next frame time interval carried in the Nth normal frame can be the time interval between the first terminal device sending the Nth normal frame and sending the N+1th normal frame.

[0077] After sending the Nth ordinary frame, the first terminal device may send the (N+1)th ordinary frame according to the second next frame time interval information carried in the Nth ordinary frame, ensuring that there is a time interval corresponding to the second next frame time interval information between two adjacent ordinary frames.

[0078] When the second terminal device receives the Nth ordinary frame sent by the first terminal device, it can receive the N+1th ordinary frame sent by the first terminal device according to the second next frame time interval information carried by the Nth ordinary frame. During the interval time corresponding to the second next frame time interval information, the second terminal device can perform operations such as sleep mode to save energy.

[0079] It should be noted that when the first terminal device sends a single ordinary frame to the second terminal device, the ordinary frame may or may not carry the second next frame time interval information, and may directly use the pre-agreed next frame time interval information. When the first terminal device sends multiple ordinary frames to the second terminal device, the ordinary frames other than the last ordinary frame may or may not carry the second next frame time interval information, and may directly use the pre-agreed next frame time interval information.

[0080] Reference Figure 5 The diagram illustrates a flowchart of another method for communication between terminal devices according to an embodiment of the present invention, which can be applied to a first terminal device.

[0081] The first terminal device is a terminal device based on a long-distance radio wide area network, specifically a terminal device based on a device-to-device mode in a long-distance radio wide area network.

[0082] Specifically, it may include the following steps:

[0083] Step 501: The first terminal device sends one or more wake-up frames so that one or more second terminal devices receive any one of the one or more wake-up frames; wherein each wake-up frame carries at least a set of addresses of the first receiving device.

[0084] The second terminal device is a terminal device based on a long-distance radio wide area network. Specifically, it can be a terminal device based on a device-to-device mode in a long-distance radio wide area network. That is, the first terminal device and the second terminal device communicate using a device-to-device mode in a long-distance radio wide area network.

[0085] like Figure 2a and Figure 2b The wake-up frame may include a preamble and a data portion. The first receiving device address set may be included in the data portion of the wake-up frame. The first receiving device address set may include the device addresses of one or more terminal devices. The device addresses of the one or more terminal devices are the device addresses of the terminal devices to which the first terminal device needs to send messages, and they can be set by the first terminal device according to actual needs.

[0086] When a first terminal device needs to send a message to one or more terminal devices, the first terminal device can first send a wake-up frame. It can send one wake-up frame or multiple wake-up frames, so that multiple wake-up frames can be supported in the device-to-device mode in long-distance radio wide area network.

[0087] like Figure 2aWhen a wake-up frame is sent to the first terminal device, the processing method is relatively simple and the wake-up rate is high. However, the amount of preamble data is very large, which leads to a large power consumption of the terminal device receiving the wake-up frame.

[0088] like Figure 2b In the case of sending multiple wake-up frames to the first terminal device, the amount of preamble data is relatively small. As long as the terminal device receives any one of the wake-up frames, it can enter a sleep state, reducing power consumption. However, the processing is more complex and the wake-up rate is slightly lower.

[0089] After receiving the wake-up frame sent by the first terminal device, the received wake-up frame can be the only wake-up frame sent by the first terminal device, or it can be any one of the multiple wake-up frames sent by the first terminal device.

[0090] Step 502: The first terminal device sends one or more ordinary frames so that the second terminal device can receive one or more ordinary frames sent by the first terminal device if it detects that the device address of the second terminal device is included in the first set of receiving device addresses.

[0091] The ordinary frame can include a preamble part and a data part. The preamble part of the wake-up frame can be different from the preamble part of the ordinary frame, so that multiple preambles can be supported in the device-to-device mode of long-distance radio wide area network.

[0092] In one example, the data portion of a normal frame may contain a second set of receiving device addresses. This second set of receiving device addresses may contain the device addresses of one or more terminal devices. These device addresses are the device addresses of the terminal devices to which the first terminal device needs to send messages. The device addresses to which the first terminal device needs to send messages can be set by the first terminal device according to its actual needs. Of course, the data portion of a normal frame also includes a content portion, such as parameter setting commands.

[0093] After reading the first set of receiving device addresses from the data portion of the wake-up frame, the second terminal device can determine whether its own device address is included in the first set of receiving device addresses. If there is only one device address in the first set of receiving device addresses, it can directly determine whether that device address is the same as its own device address.

[0094] If the device address of the first terminal device is not included in the set of device addresses of the first receiving end, it means that the first terminal device does not need to send a message to the second terminal device. In this case, when the first terminal device continues to send ordinary frames, the second terminal device can directly ignore them and not receive them.

[0095] If the device address of the first terminal device is included in the first receiving device address set, it indicates that the first terminal device needs to send a message to the second terminal device. In this case, while the first terminal device continues to send ordinary frames, the second terminal device can further receive subsequent ordinary frames from the first terminal device.

[0096] Specifically, such as Figure 2a and Figure 2b When the communication packet data volume is small, the first terminal device can send a normal frame. When the communication packet data volume is large, it can also send multiple normal frames, so that multiple normal frames can be supported in the device-to-device mode in long-distance radio wide area network.

[0097] In fact, by setting the first set of receiving device addresses, after the first terminal device sends a message, other terminal devices can know whether it is a terminal device that needs to receive the message. If it is not a terminal device that needs to receive the message, it is ignored; if it is a terminal device that needs to receive the message, it can receive the message. This allows a message to be sent to multiple terminal devices. For example, if terminal device A wants to send a parameter setting message to 100 terminal devices, it used to need to send 100 messages one by one to each terminal device. Now, it only needs to send one message to receive it from all 100 terminal devices.

[0098] In one embodiment of the present invention, each wake-up frame may further carry first next frame time interval information, and step 502 may include:

[0099] The first terminal device sends a first normal frame according to the first next frame time interval information carried in one or more wake-up frames, so that the second terminal device, when it detects that the device address of the second terminal device is included in the first receiving device address set, receives the first normal frame sent by the first terminal device according to the first next frame time interval information carried in the received wake-up frame.

[0100] The first next frame time interval information can be included in the data part of the wake-up frame. This first next frame time interval information can be used to determine the time information for receiving the first normal frame after the wake-up frame. That is, the first next frame time interval information can be the time interval information between the wake-up frame and the normal frame. For example, the first next frame time interval can be the time interval between the time when the first terminal device sends the wake-up frame and the time interval between the time when the first terminal device sends the first normal frame.

[0101] It should be noted that when the first terminal device sends multiple wake-up frames to the second terminal device, each wake-up frame carries the first next frame time interval information, and the first next frame time interval information carried by each wake-up frame is different. For example, the first wake-up frame writes 1.08 seconds, the second wake-up frame writes 1.03 seconds, and so on. When the first terminal device sends a single wake-up frame to the second terminal device, the wake-up frame may or may not carry the first next frame time interval information, and may directly use the pre-agreed next frame time interval information.

[0102] After reading the first set of receiving device addresses from the data portion of the wake-up frame, the second terminal device can determine whether its own device address is included in the first set of receiving device addresses. If there is only one device address in the first set of receiving device addresses, it can directly determine whether that device address is the same as its own device address.

[0103] If the device address of the first terminal device is not included in the set of device addresses of the first receiving end, it means that the first terminal device does not need to send a message to the second terminal device. In this case, when the first terminal device continues to send ordinary frames, the second terminal device can directly ignore them and not receive them.

[0104] If its own device address is included in the first receiving end device address set, it indicates that the first terminal device needs to send a message to the second terminal device. The second terminal device can further obtain the first next frame time interval information from the data part of the wake-up frame.

[0105] Since the first next frame time interval information indicates the time interval for sending the first normal frame, the second terminal device can receive the first normal frame sent by the first terminal device according to the first next frame time interval information. During the interval time corresponding to the first next frame time interval information, the second terminal device can perform operations such as sleep mode to save energy.

[0106] It should be noted that if the first terminal device sends only one normal frame, then the first normal frame referred to here is that normal frame, and there are no subsequent different frames. If the first terminal device sends multiple normal frames, then there will be other normal frames after the first normal frame.

[0107] In one embodiment of the present invention, when there are multiple ordinary frames, the Nth ordinary frame carries the second next frame time interval information, where N is a positive integer greater than or equal to 1. Step 502 may further include:

[0108] After the first terminal device has sent the Nth ordinary frame, it sends the N+1th ordinary frame according to the second next frame time interval information carried in the Nth ordinary frame, so that the second terminal device, after receiving the Nth ordinary frame sent by the first terminal device, receives the N+1th ordinary frame sent by the first terminal device according to the second next frame time interval information carried in the Nth ordinary frame.

[0109] In the case of multiple normal frames, all normal frames except the last normal frame (including the first normal frame) can carry the second next frame time interval information. The second next frame time interval information can be included in the data part of the normal frame and can be used to determine the time to receive the next normal frame.

[0110] Specifically, the second next frame time interval information can be the time interval information between two adjacent normal frames. It can be set to be the same as the first next frame time interval information. For example, the second next frame time interval carried in the Nth normal frame can be the time interval between the first terminal device sending the Nth normal frame and sending the N+1th normal frame.

[0111] After sending the Nth ordinary frame, the first terminal device may send the (N+1)th ordinary frame according to the second next frame time interval information carried in the Nth ordinary frame, ensuring that there is a time interval corresponding to the second next frame time interval information between two adjacent ordinary frames.

[0112] When the second terminal device receives the Nth ordinary frame sent by the first terminal device, it can receive the N+1th ordinary frame sent by the first terminal device according to the second next frame time interval information carried by the Nth ordinary frame. During the interval time corresponding to the second next frame time interval information, the second terminal device can perform operations such as sleep mode to save energy.

[0113] It should be noted that when the first terminal device sends a single ordinary frame to the second terminal device, the ordinary frame may or may not carry the second next frame time interval information, and may directly use the pre-agreed next frame time interval information. When the first terminal device sends multiple ordinary frames to the second terminal device, the ordinary frames other than the last ordinary frame may or may not carry the second next frame time interval information, and may directly use the pre-agreed next frame time interval information.

[0114] In this embodiment of the invention, a first terminal device sends one or more wake-up frames to enable one or more second terminal devices to receive any one of the wake-up frames. Each wake-up frame carries at least a first set of receiving device addresses. Then, one or more ordinary frames are sent. If the second terminal device detects that the first set of receiving device addresses contains the device address of the second terminal device, it can receive one or more ordinary frames sent by the first terminal device. This enables the sending device to communicate with multiple receiving devices through a single message, supports multiple receiving devices, multiple wake-up frames, and multiple ordinary frames, improves communication efficiency, and reduces resource consumption.

[0117] 1. Terminal device B and terminal device C receive the wake-up frame preamble portion sent by terminal device A.

[0118] 2. Terminal device B and terminal device C receive the wake-up frame data portion sent by terminal device A.

[0119] 3. If terminal device B determines that the receiving device address in the wake-up frame data part is the same as its own device address, it will read the next frame time interval information in the wake-up frame data part.

[0120] 4. If terminal device C determines that the receiving device address in the wake-up frame data portion is different from its own device network address, it will not perform any further processing.

[0121] 5. Terminal device B receives the preamble portion of the ordinary frame sent by terminal device A.

[0122] The time interval between steps 2 and 5 is the time interval between the next frame in the wake-up frame data section.
