Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a flowchart of steps of a method for a terminal device to communicate with a terminal device, which may be applied to a second terminal device, is shown.
The second terminal device is a terminal device based on a long-distance radio wide area network, and may specifically be a terminal device based on a device-to-device mode in the long-distance radio wide area network.
Specifically, the method can comprise the following steps:
the first terminal device is a terminal device based on a long-distance radio wide area network, and may specifically be a terminal device based on a device-to-device mode in the long-distance radio wide area network, that is, the first terminal device and the second terminal device communicate in the device-to-device mode in the long-distance radio wide area network.
As shown in fig. 2a and fig. 2b, the wake-up frame may include a preamble part and a data part, the first receiver device address set may be included in the data part of the wake-up frame, the first receiver device address set may include device addresses of one or more terminal devices, the device addresses of the one or more terminal devices are device addresses of terminal devices to which the first terminal device needs to send a message, and the device addresses may be set by the first terminal device according to actual requirements.
When the first terminal device needs to send a message to one or more terminal devices, the first terminal device may send a wakeup frame, which may send one wakeup frame or may send multiple wakeup frames, so that the device-to-device mode in the long-distance radio wide area network may support multiple wakeup frames.
As shown in fig. 2a, in the case that the first terminal device sends an awake frame, the processing method is simple and the awake rate is high in the case of sending an awake frame, but the amount of preamble data is large, which results in large energy consumption of the terminal device receiving the awake frame.
As shown in fig. 2b, in the case that the first terminal device sends a plurality of wake-up frames, the preamble data amount is small when the first terminal device sends a plurality of wake-up frames, and the terminal device can enter the sleep state only by receiving any one wake-up frame, so as to reduce energy consumption.
After receiving the wake-up frame sent by the first terminal device, the received wake-up frame may be the only wake-up frame sent by the first terminal device, or any one of the wake-up frames sent by the first terminal device.
The normal frame may include a preamble part and a data part, and the preamble in the preamble part of the wake-up frame and the preamble in the preamble part of the normal frame may be different, so that multiple preambles may be supported in a device-to-device mode in a long-range radio wide area network.
In an example, the data portion of the normal frame may include a second receiver device address set, where the second receiver device address set may include device addresses of one or more terminal devices, where the device addresses of the one or more terminal devices are device addresses of terminal devices to which the first terminal device needs to send a message, and the terminal devices to which the first terminal device needs to send a message may be set by the first terminal device according to actual requirements. Of course, the data portion of the normal frame also contains a specific content portion, e.g., the specific content portion may include a parameter setting command.
After reading the first receiving end device address set from the data portion of the wakeup frame, the second terminal device may determine whether its own device address is included in the first receiving end device address set, and may directly determine whether the device address is the same as its own device address when only one device address exists in the first receiving end device address set.
If the own device address is not contained in the first receiving end device address set, the first terminal device is characterized not to send a message to the second terminal device, and when the first terminal device continues to send the common frame, the second terminal device can directly ignore the common frame and does not receive the common frame.
If the device address of the second terminal device is included in the first receiving end device address set, which indicates that the first terminal device needs to send a message to the second terminal device, the second terminal device may further receive a subsequent normal frame from the first terminal device when the first terminal device continues to send the normal frame.
Specifically, as shown in fig. 2a and 2b, the first terminal device may transmit one normal frame when the packet data amount is small, and may also transmit a plurality of normal frames when the packet data amount is large, so that a plurality of normal frames may be supported in the device-to-device mode in the long-range radio wide area network.
In fact, by setting the address set of the first receiving end device, after the first terminal device sends a message, the other terminal devices can know whether the first terminal device is a terminal device that needs to receive the message, ignore the message if the first terminal device is not a terminal device that needs to receive the message, and further receive the message if the first terminal device is a terminal device that needs to receive the message, so that one message can be sent to multiple terminal devices, for example, terminal device a needs to send a parameter setting message to 100 terminal devices, originally needs to send 100 messages one by one according to the terminal devices, and now only needs to send 1 message, that is, 100 terminal devices can receive the message.
In the embodiment of the present invention, the second terminal device receives any one of one or more wake-up frames sent by the first terminal device, where each wake-up frame carries at least the first receiving end device address set, and receives one or more common frames sent by the first terminal device when detecting that the first receiving end device address set includes the device address of the second terminal device, so that the sending end device communicates with multiple receiving end devices through one message, and supports the situations of multiple receiving end devices, multiple wake-up frames, and multiple common frames, thereby improving communication efficiency and reducing resource consumption.
Referring to fig. 3, a flowchart illustrating steps of another method for a terminal device to communicate with a terminal device, which may be applied to a second terminal device, is provided in an embodiment of the present invention.
Specifically, the method can comprise the following steps:
The first next frame time interval information may be included in the data portion of the wakeup frame, and the first next frame time interval information may be used to determine time information for receiving a first normal frame after the wakeup frame, that is, the first next frame time interval information may be time interval information between the wakeup frame and the normal frame, for example, the first next frame time interval may be a time for the first terminal device to send the wakeup frame and a time interval for the first terminal device to send the first normal frame.
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 first next frame time interval information, and the first next frame time interval information carried by each wake-up frame is different, for example, 1.08 seconds is written in the first wake-up frame, 1.03 seconds is written in the second wake-up frame, and so on. When the first terminal device sends an awake frame to the second terminal device, the awake frame may carry the first next frame time interval information, or may directly adopt the pre-agreed next frame time interval information without carrying the first next frame time interval information.
When the first terminal device needs to send a message to one or more terminal devices, the first terminal device may send a wakeup frame first, and may send one wakeup frame or multiple wakeup frames, so that multiple wakeup frames may be supported in a device-to-device mode in a long-distance radio wide area network.
After receiving the wake-up frame sent by the first terminal device, the received wake-up frame may be the only wake-up frame sent by the first terminal device, or any one of the wake-up frames sent by the first terminal device.
If the own device address is not contained in the first receiving end device address set, the first terminal device is characterized not to send a message to the second terminal device, and when the first terminal device continues to send the common frame, the second terminal device can directly ignore the common frame and does not receive the common frame.
If the device address of the second terminal device is included in the first receiving end device address set, the first terminal device is characterized to send a message to the second terminal device, and the second terminal device can further obtain the first next frame time interval information from the data part of the wakeup frame.
Because the first next frame time interval information indicates the time interval for sending the first normal frame, the second terminal device may receive the first normal frame sent by the first terminal device according to the first next frame time interval information, and in the interval time corresponding to the first next frame time interval information, the second terminal device may perform operations such as sleep, and the like, thereby saving energy consumption.
It should be noted that, when the first terminal device only sends one normal frame, the first normal frame referred to herein is the normal frame, and there are no subsequent different frames. In case that the first terminal device transmits a plurality of normal frames, there are other normal frames after the first normal frame.
Referring to fig. 4, a flowchart of steps of another method for a terminal device to communicate with a terminal device, which may be applied to a second terminal device, is shown.
Specifically, the method can comprise the following steps:
For the case that there are multiple normal frames, the other normal frames (including the first normal frame) except the last normal frame may carry second next frame time interval information, and the second next frame time interval information may be included in the data portion of the normal frame, which may be used to determine the time to receive the next normal frame.
Specifically, the second next frame time interval information may be time interval information between two adjacent common frames, and may 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 common frame may be a time interval for the first terminal device to transmit the nth common frame and a time interval for transmitting the N +1 th common frame.
The first terminal device may send the (N + 1) th normal frame according to the second next frame time interval information carried by the nth normal frame after the nth normal frame is sent by the first terminal device, so as to ensure that a time interval corresponding to the second next frame time interval information exists between two adjacent normal frames,
the second terminal device may receive the (N + 1) th normal frame sent by the first terminal device according to the second next frame time interval information carried by the nth normal frame when receiving the nth normal frame sent by the first terminal device, and may perform operations such as sleep and the like within an interval time corresponding to the second next frame time interval information, thereby saving energy consumption.
It should be noted that, in the case that the first terminal device sends a normal frame to the second terminal device, the normal frame may carry the second next frame time interval information, or may not carry the second next frame time interval information, but directly adopt the predetermined next frame time interval information. When the first terminal device sends a plurality of normal frames to the second terminal device, the other normal frames except the last normal frame may carry the second next frame time interval information, or may not carry the second next frame time interval information, but directly adopt the predetermined next frame time interval information.
Referring to fig. 5, a flowchart illustrating steps of another method for a terminal device to communicate with a terminal device, which may be applied to a first terminal device, according to an embodiment of the present invention is shown.
The first terminal device is a terminal device based on a long-distance radio wide area network, and may specifically be a terminal device based on a device-to-device mode in the long-distance radio wide area network.
Specifically, the method can comprise the following steps:
The second terminal device is a terminal device based on a long-distance radio wide area network, and may specifically be a terminal device based on a device-to-device mode in the long-distance radio wide area network, that is, the first terminal device and the second terminal device communicate in the device-to-device mode in the long-distance radio wide area network.
As shown in fig. 2a and fig. 2b, the wake-up frame may include a preamble part and a data part, the first receiver device address set may be included in the data part of the wake-up frame, the first receiver device address set may include device addresses of one or more terminal devices, the device addresses of the one or more terminal devices are device addresses of terminal devices to which the first terminal device needs to send a message, and the device addresses may be set by the first terminal device according to actual requirements.
When the first terminal device needs to send a message to one or more terminal devices, the first terminal device may send a wakeup frame, which may send one wakeup frame or may send multiple wakeup frames, so that the device-to-device mode in the long-distance radio wide area network may support multiple wakeup frames.
As shown in fig. 2a, in the case that the first terminal device sends an awake frame, the processing method is simple and the awake rate is high when sending an awake frame, but the amount of preamble data is large, which results in large energy consumption of the terminal device receiving the awake frame.
As shown in fig. 2b, in the case that the first terminal device sends a plurality of wake-up frames, the preamble data amount is small when the first terminal device sends a plurality of wake-up frames, and the terminal device can enter the sleep state only by receiving any one wake-up frame, so as to reduce energy consumption.
After receiving the wake-up frame sent by the first terminal device, the received wake-up frame may be the only wake-up frame sent by the first terminal device, or any one of the wake-up frames sent by the first terminal device.
The normal frame may include a preamble part and a data part, and the preamble in the preamble part of the wake-up frame and the preamble in the preamble part of the normal frame may be different, so that multiple preambles may be supported in a device-to-device mode in a long-range radio wide area network.
In an example, the data portion of the normal frame may include a second receiver device address set, where the second receiver device address set may include device addresses of one or more terminal devices, where the device addresses of the one or more terminal devices are device addresses of terminal devices to which the first terminal device needs to send a message, and the terminal devices to which the first terminal device needs to send a message may be set by the first terminal device according to actual requirements. Of course, the data portion of the normal frame also contains a specific content portion, e.g., the specific content portion may include a parameter setting command.
After reading the first receiving end device address set from the data portion of the wakeup frame, the second terminal device may determine whether its own device address is included in the first receiving end device address set, and may directly determine whether the device address is the same as its own device address when only one device address exists in the first receiving end device address set.
If the own device address is not contained in the first receiving end device address set, the first terminal device is characterized not to send a message to the second terminal device, and when the first terminal device continues to send the common frame, the second terminal device can directly ignore the common frame and does not receive the common frame.
If the device address of the second terminal device is included in the first receiving end device address set, which indicates that the first terminal device needs to send a message to the second terminal device, the second terminal device may further receive a subsequent normal frame from the first terminal device when the first terminal device continues to send the normal frame.
Specifically, as shown in fig. 2a and 2b, the first terminal device may transmit one normal frame when the packet data amount is small, and may also transmit a plurality of normal frames when the packet data amount is large, so that a plurality of normal frames may be supported in the device-to-device mode in the long-range radio wide area network.
In fact, by setting the address set of the first receiving end device, after the first terminal device sends a message, the other terminal devices can know whether the first terminal device is a terminal device that needs to receive the message, ignore the message if the first terminal device is not a terminal device that needs to receive the message, and further receive the message if the first terminal device is a terminal device that needs to receive the message, so that one message can be sent to multiple terminal devices, for example, terminal device a needs to send a parameter setting message to 100 terminal devices, originally needs to send 100 messages one by one according to the terminal devices, and now only needs to send 1 message, that is, 100 terminal devices can receive the message.
In an embodiment of the present invention, each wakeup frame may further carry first next frame time interval information, and step 502 may include:
the first terminal device sends a first common frame according to first next frame time interval information carried in one or more wake-up frames, so that the second terminal device receives the first common frame sent by the first terminal device according to the first next frame time interval information carried in the received wake-up frame when detecting that the first receiving end device address set contains the device address of the second terminal device.
The first next frame time interval information may be included in the data portion of the wakeup frame, and the first next frame time interval information may be used to determine time information for receiving a first normal frame after the wakeup frame, that is, the first next frame time interval information may be time interval information between the wakeup frame and the normal frame, for example, the first next frame time interval may be a time for the first terminal device to send the wakeup frame and a time interval for the first terminal device to send the first normal frame.
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 first next frame time interval information, and the first next frame time interval information carried by each wake-up frame is different, for example, 1.08 seconds is written in the first wake-up frame, 1.03 seconds is written in the second wake-up frame, and so on. When the first terminal device sends an awake frame to the second terminal device, the awake frame may carry the first next frame time interval information, or may directly adopt the pre-agreed next frame time interval information without carrying the first next frame time interval information.
After reading the first receiving end device address set from the data portion of the wakeup frame, the second terminal device may determine whether its own device address is included in the first receiving end device address set, and may directly determine whether the device address is the same as its own device address when only one device address exists in the first receiving end device address set.
If the own device address is not contained in the first receiving end device address set, the first terminal device is characterized not to send a message to the second terminal device, and when the first terminal device continues to send the common frame, the second terminal device can directly ignore the common frame and does not receive the common frame.
If the device address of the second terminal device is included in the first receiving end device address set, the first terminal device is characterized to send a message to the second terminal device, and the second terminal device can further obtain the first next frame time interval information from the data part of the wakeup frame.
Because the first next frame time interval information indicates the time interval for sending the first normal frame, the second terminal device may receive the first normal frame sent by the first terminal device according to the first next frame time interval information, and in the interval time corresponding to the first next frame time interval information, the second terminal device may perform operations such as sleep, and the like, thereby saving energy consumption.
It should be noted that, when the first terminal device only sends one normal frame, the first normal frame referred to herein is the normal frame, and there are no subsequent different frames. In case the first terminal device transmits a plurality of normal frames, there are other normal frames after the first normal frame.
In an embodiment of the present invention, in a case that there are multiple normal frames, an nth normal frame carries second next frame time interval information, where N is a positive integer greater than or equal to 1, and step 502 may further include:
and the first terminal equipment sends the (N + 1) th common frame according to the second next frame time interval information carried by the nth common frame under the condition that the nth common frame is sent, so that the second terminal equipment receives the (N + 1) th common frame sent by the first terminal equipment according to the second next frame time interval information carried by the nth common frame under the condition that the nth common frame sent by the first terminal equipment is received.
For the case that there are multiple normal frames, the other normal frames (including the first normal frame) except the last normal frame may carry second next frame time interval information, and the second next frame time interval information may be included in the data portion of the normal frame, which may be used to determine the time to receive the next normal frame.
Specifically, the second next frame time interval information may be time interval information between two adjacent common frames, and may 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 common frame may be a time interval when the first terminal device sends the nth common frame and a time interval when the first terminal device sends the N +1 th common frame.
The first terminal device may send the (N + 1) th normal frame according to the second next frame time interval information carried by the nth normal frame after the nth normal frame is sent by the first terminal device, so as to ensure that a time interval corresponding to the second next frame time interval information exists between two adjacent normal frames,
the second terminal device may receive the (N + 1) th normal frame sent by the first terminal device according to the second next frame time interval information carried by the nth normal frame when receiving the nth normal frame sent by the first terminal device, and may perform operations such as sleep and the like within an interval time corresponding to the second next frame time interval information, thereby saving energy consumption.
It should be noted that, in the case that the first terminal device sends a normal frame to the second terminal device, the normal frame may carry the second next frame time interval information, or may not carry the second next frame time interval information, but directly adopts the predetermined next frame time interval information. When the first terminal device sends a plurality of normal frames to the second terminal device, the other normal frames except the last normal frame may carry the second next frame time interval information, or may not carry the second next frame time interval information, but directly adopt the predetermined next frame time interval information.
In the embodiment of the present invention, a first terminal device sends one or more wake-up frames, so that one or more second terminal devices receive any wake-up frame in the one or more wake-up frames, each wake-up frame carries at least a first receiving end device address set, and then sends one or more common frames, and the second terminal device can receive the one or more common frames sent by the first terminal device under the condition that the first receiving end device address set is detected to include a device address of the second terminal device, thereby implementing that a sending end device communicates with a plurality of receiving end devices through one message, supporting the situations of a plurality of receiving end devices, a plurality of wake-up frames, and a plurality of common frames, improving communication efficiency, and reducing resource consumption.
The following is an exemplary description of the communication procedure in device-to-device mode in a long-range radio wide area network, with reference to fig. 6 and 7:
in fig. 6, terminal device a needs to send a message to terminal device B, and does not need to send a message to terminal device C, and the specific process is as follows:
1. and the terminal equipment B and the terminal equipment C receive the preamble part of the wake-up frame sent by the terminal equipment A.
2. Receiving, by the terminal device B and the terminal device C, a wake-up frame data portion sent by the terminal device a, where the wake-up frame data portion at least includes: the receiver device address (i.e. the first receiver device address set, which may only include the device address of one terminal device), and the next frame time interval information (i.e. the second receiver device address).
3. And the terminal equipment B judges that the address of the receiving end equipment in the awakening frame data part is the same as the own equipment address, and reads the time interval information of the next frame in the awakening frame data part.
4. And the terminal equipment C judges that the address of the receiving end equipment in the awakening frame data part is different from the network address of the equipment of the terminal equipment C, and does not perform subsequent processing.
5. Terminal device B receives the normal frame preamble portion sent by terminal device a.
Wherein, the time interval of the step 2 and the step 5 is the time interval of the next frame in the wakeup frame data part.
