[0002] Currently, in a network-free environment, a solution has been proposed to perform short-range communication between two devices through the long range mode of Bluetooth.

[0003] However, if the communication is only carried out through the long range mode of Bluetooth, the communication distance is too short, especially when there are obstacles between the two devices, the communication distance will be greatly reduced, making it difficult to send messages over long distances, reducing the transmission distance and diffusion range of messages in a networkless environment.

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0019] The message forwarding method and device, electronic device, and readable storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0020] like Figure 1 As shown, an embodiment of the present application provides a message forwarding method, which is applied to a first device. The method may include the following S102 to S106:

[0021] S102: Receive a first message sent by a second device.

[0022] The message forwarding method proposed in the embodiment of the present application is applied to a first device, which may specifically be a smart electronic device with Bluetooth function, such as a smart phone, a tablet computer, a laptop computer, and a smart watch, and is not specifically limited here.

[0023] The second device may be an electronic device that initially generates and sends the first message, or may be an electronic device that relays and forwards the first message, and no specific limitation is made here.

[0024] Furthermore, the first message is a message sent by the second device via Bluetooth broadcast.

[0025] In actual application, the first message may specifically be a distress message, a help message, a location message, or other message sent in a network-free environment, and no specific limitation is made herein.

[0026] S104: When the first device has not processed the first message, update the queue of messages to be forwarded according to the first message to obtain at least one second message.

[0027] The message queue to be forwarded is established in the first device, and is used to store messages that need to be forwarded by the first device.

[0028] Specifically, in the message forwarding method provided in the embodiment of the present application, the first device can receive the first message sent by the second device via Bluetooth broadcast, and the first device further determines whether the first message has been processed before, that is, whether the first message has been received before. In the case where the first device determines that it has not processed the first message, the first device updates its own queue of messages to be forwarded based on the first message, so as to save the latest received messages to be forwarded in the queue of messages to be forwarded, and obtain at least one second message to be forwarded.

[0029] S106: When a heartbeat signal from at least one third device is received, broadcast at least one second message in the queue of messages to be forwarded.

[0030] The third device is an electronic device that can forward messages as a relay device in a networkless environment, and the third device is different from the first device and the second device.

[0031] In the message forwarding method provided in the embodiment of the present application, electronic devices that can forward messages as relay devices in a networkless environment will continue to send heartbeat signals to the outside so that other electronic devices can sense their own existence.

[0032] On this basis, in the message forwarding method provided in the embodiment of the present application, after updating its own queue of messages to be forwarded, the first device will judge whether there is a third device other than itself and the second device in its surrounding environment based on the heartbeat signals of other electronic devices received by itself. In the case where the first device receives the heartbeat signal of at least one third device, that is, in the case where the first device perceives that there is at least one third device in its surrounding environment, the first device broadcasts at least one second message stored in the queue of messages to be forwarded to send the second message in the queue of messages to be forwarded to the third device, so that the third device can continue to forward the second message to other electronic devices. In this way, on the one hand, a message sent by an electronic device can be forwarded to another electronic device through a relay device in a networkless environment, thereby improving the transmission distance and diffusion range of the message in a networkless environment; on the other hand, the message is broadcast only when it is perceived that there are other electronic devices in the surrounding environment that can relay and forward messages, which can avoid the relay device from doing useless work, reduce the power consumption of the relay device, and improve the endurance of the relay device, so that the relay device can forward the message to more devices, further improving the diffusion range of the message in a networkless environment.

[0033] The above-mentioned message forwarding method provided in the embodiment of the present application is applied to the first device, and the first device receives the first message sent by the second device; when the first device has not processed the first message, the queue of messages to be forwarded is updated according to the first message to obtain at least one second message; when the heartbeat signal of at least one third device is received, at least one second message in the queue of messages to be forwarded is broadcast. Through the above-mentioned message forwarding method, the first device is used as a relay device, and after receiving the first message of the second device, when it is perceived that there is a third device other than the second device in the surrounding environment, the first message is forwarded to the third device in the form of broadcasting. In this way, on the one hand, the message sent by one device can be forwarded to another device through the relay device in a networkless environment, thereby improving the transmission distance and diffusion range of the message in the networkless environment; on the other hand, the message is broadcast only when other devices are perceived in the surrounding environment, which can also reduce the power consumption of the relay device and improve the endurance of the relay device, so that the relay device can forward the message to more devices, further improving the diffusion range of the message in the networkless environment.

[0034] In the embodiment of the present application, after the above S102, the above message forwarding method further includes the following S108 to S112:

[0035] S108: Obtain a first field in the first message.

[0036] Among them, the first field is used to indicate the number of devices that can forward the first message. Each time the first message is forwarded by a different device, the value of the first field in the first message is reduced by 1. When the value of the first field in the first message is less than or equal to a preset value, the first message will no longer be forwarded.

[0037] In actual application, the above preset values ​​may be specifically values ​​such as 0 and 1. Those skilled in the art may set specific values ​​of the above preset values ​​according to actual conditions, and no specific limitation is made here.

[0038] S110: When the value of the first field is greater than a preset value, determine the processing status of the first message.

[0039] The processing status of the first message is used to indicate whether the first device has processed the first message.

[0040] Specifically, in the message forwarding method provided in the embodiment of the present application, after receiving the first message broadcasted by the second device, the first device will also extract the first field in the first message and determine whether the value of the first field is greater than the preset value. In the case where the value of the first field is greater than the preset value, it means that the number of electronic devices that have forwarded the first message does not exceed the upper limit of the number of devices that can forward the first message, which means that the first message can still be forwarded by the first device. At this time, the first device continues to perform subsequent processing on the first message to determine whether the first message has been processed before, that is, to determine whether the first message has been received before.

[0041] S112: When the value of the first field is less than or equal to a preset value, the first message is no longer forwarded.

[0042] Specifically, in the message forwarding method provided in the embodiment of the present application, when the value of the first field in the first message is less than or equal to the preset value, it means that the number of electronic devices that have forwarded the first message has exceeded the upper limit of the number of devices that can forward the first message. At this time, the first device directly regards the first message as a redundant message and no longer performs subsequent processing on the first message, that is, the first message is no longer forwarded. In this way, by adding the first field in the first message and limiting the number of devices that can forward the first message, the first message can be prevented from being relayed and forwarded without restriction.

[0043] In the above embodiment provided by the present application, after receiving the first message sent by the second device, the first field in the first message is obtained; when the value of the first field is greater than the preset value, the processing status of the first message is determined, and the processing status is used to indicate whether the first device has processed the first message; when the value of the first field is less than or equal to the preset value, the first message is no longer forwarded; wherein, the first field is used to indicate the number of devices that can forward the first message, and each time the first message is forwarded by a different device, the value of the first field in the first message is reduced by 1. In this way, by adding the first field to the first message, the number of devices that can forward the first message is limited, and the first message can be prevented from being relayed and forwarded without restriction.

[0044] In the embodiment of the present application, the step of determining the processing status of the first message may specifically include the following S114 to S118:

[0045] S114: Remove the first field in the first message to obtain a third message.

[0046] The first field is used to indicate the number of devices that can forward the first message. As different electronic devices forward the first message, the value of the first field in the first message gradually decreases.

[0047] Furthermore, the third message is obtained by removing the first field from the first message.

[0048] S116: When there is a historical message that is consistent with the third message, it is determined that the first message has been processed.

[0049] The historical message is a message previously received by the first device from the second device or other electronic devices broadcast via Bluetooth.

[0050] Furthermore, the historical message does not include the first field, and the historical message may be obtained by removing the first field from the message previously received by the first device.

[0051] It is understandable that electronic devices send messages via Bluetooth broadcasting, and message communication has no directionality, so surrounding devices can all receive Bluetooth broadcast messages. Therefore, an electronic device will receive more redundant messages.

[0052] On this basis, in the message forwarding method provided in the embodiment of the present application, in the process of determining the processing status of the first message by the first device, after the first device receives the first message, since the first field in the first message will decrease as the number of forwarding devices increases, the first device will remove the first field in the first message, and obtain a third message that does not contain the first field, and then compare the third message with the previously received historical message that does not contain the first field. Further, in the case where there is a historical message in the first device that is consistent with the third message, it means that the first device has previously received the first message, that is, it is determined that the first device has processed the first message. At this time, the first device directly regards the first message as a redundant message and no longer performs subsequent processing on the first message.

[0053] S118: When there is no historical message that is consistent with the third message, it is determined that the first message has not been processed.

[0054] Specifically, in the message forwarding method provided in the embodiment of the present application, after the electronic device compares the third message with the previously received historical message that does not contain the first field, if there is no historical message in the first device that is consistent with the third message, it means that the first device has not received the first message before, that is, it is determined that the first device has not processed the first message. At this time, the first device continues to perform subsequent processing on the first message and continues to perform the relay forwarding operation on the first message. In this way, it can avoid the first device from repeatedly processing the first message and avoid the first device from processing redundant messages, thereby reducing the power consumption of the relay device and improving the battery life of the relay device.

[0055] In the above embodiment provided by the present application, in the process of determining the processing status of the first message, the first field in the first message is removed to obtain the third message; when there is a historical message that is consistent with the third message, it is determined that the first message has been processed; when there is no historical message that is consistent with the third message, it is determined that the first message has not been processed. In this way, it is possible to avoid the first device from repeatedly processing the first message and avoid the first device from processing redundant messages, thereby reducing the power consumption of the relay device and improving the battery life of the relay device.

[0056] In the embodiment of the present application, the message source of the first message is the target device, the first message includes a second field, and the step of updating the queue of messages to be forwarded according to the first message may specifically include the following S120 to S124:

[0057] S120: Obtain the message source of the historical message in the message queue to be forwarded.

[0058] The message source of the historical message is used to indicate the electronic device that initially generates and sends the historical message.

[0059] S122: If there is no historical message whose source is the target device, after reducing the value of the first field in the first message by 1, the first message is saved as the second message in the queue of messages to be forwarded.

[0060] The target device is the message source of the first message, that is, the target device is the electronic device that initially generates and sends the first message.

[0061] Further, the target device is different from the first device and the third device. The target device and the second device may be the same device, or may be different devices, which is not specifically limited here.

[0062] Specifically, in the message forwarding method provided in the embodiment of the present application, in the process of the first device updating its own queue of messages to be forwarded based on the first message, the first device will obtain the message source of each historical message saved in the queue of messages to be forwarded. If there is no historical message with the same message source as the first message in the queue of messages to be forwarded, that is, if there is no historical message with the message source of the target device in the queue of messages to be forwarded, it means that the first device has never received a message sent by the target device, and the first message is the latest message of the target device received by the first device. At this time, the first device directly subtracts 1 from the value of the first field in the first message, and saves the processed first message as the second message to the queue of messages to be forwarded.

[0063] S124: In the case that there is a historical message whose source is the target device, the one with the larger value of the second field in the first message and the historical message is determined as the second message, the value of the first field in the second message is reduced by 1, and the second message is saved in the queue of messages to be forwarded.

[0064] Among them, the second field is used to indicate the update status of the message content carried by the first message. When the message content of the first message is updated compared to the fourth message previously sent by the target device, the value of the second field of the first message is increased by 1 compared to the second field of the fourth message.

[0065] For example, in the case where the first message is a distress message generated and broadcast by the target device, when the user location information, user physical condition information, etc. contained in the distress message changes compared to the historical distress message sent last time, the target device will, when broadcasting the distress message, add 1 to the value of the second field in the current distress message based on the value of the second field of the historical distress message sent last time, so that the electronic device receiving the distress message can distinguish between the latest updated distress message and the historical distress message, thereby avoiding the electronic device from continuing to forward messages whose content is invalid, thereby ensuring the accuracy of forwarding the message content.

[0066] On the contrary, when the message content of the distress message currently sent by the target device has not changed compared to the historical distress message it sent last time, the target device does not change the value of the second field of the current distress message, and the current distress message has the same value as the second field of the historical distress message sent last time. At this time, excluding the first field, the message content of the current distress message is the same as that of the historical distress message sent last time.

[0067] Specifically, in the message forwarding method provided in the embodiment of the present application, after the first device obtains the message source of each historical message saved in the message queue to be forwarded, if there is a historical message with the same message source as the first message in the message queue to be forwarded, that is, if there is a historical message with the message source of the target device in the message queue to be forwarded, it means that the first device has received the message sent by the target device. At this time, the first device compares the numerical value of the second field of the historical message with the message source of the target device in the message queue to be forwarded and the first message. In the case where the numerical value of the second field of the historical message is greater than or equal to the numerical value of the second field of the first message, the first device determines that the historical message is the latest message of the target device received by the first device, and still retains the historical message as the second message in the message queue to be forwarded. In the case where the numerical value of the second field of the historical message is less than the numerical value of the second field of the first message, the first device determines that the first message is the latest message of the target device received by the first device, and after subtracting 1 from the numerical value of the first field in the first message, the processed first message is used as the second message, and the historical message with the message source of the target device in the message queue to be forwarded is replaced by the second message, and the second message is saved in the message queue to be forwarded. In this way, only the latest update messages of different electronic devices are saved in the message queue to be forwarded, which can prevent the first device from forwarding messages whose message contents are invalid, thereby ensuring the accuracy of forwarding the message contents.

[0068] In the above embodiment provided by the present application, the source of the first message is the target device, the first message includes a second field, and in the process of updating the queue of messages to be forwarded according to the first message, the source of the historical message in the queue of messages to be forwarded is obtained; in the case where there is no historical message whose source is the target device, the value of the first field in the first message is reduced by 1, and the first message is saved as the second message to the queue of messages to be forwarded; in the case where there is a historical message whose source is the target device, the one with the larger value of the second field in the first message and the historical message is determined as the second message, and the value of the first field in the second message is reduced by 1, and the second message is saved to the queue of messages to be forwarded; wherein the second field is used to indicate the update status of the message content carried by the first message, and when the message content of the first message is updated compared with the fourth message sent by the target device last time, the value of the second field of the first message is increased by 1 compared with the value of the second field of the fourth message. In this way, only the latest update messages of different electronic devices are saved in the queue of messages to be forwarded, which can avoid the first device forwarding messages whose message content is invalid, and ensure the accuracy of message content forwarding.

[0069] In the embodiment of the present application, the step of broadcasting at least one second message in the queue of messages to be forwarded may specifically include the following S126 and S128:

[0070] S126: Broadcast at least one second message in the queue of messages to be forwarded and continue for a first duration.

[0071] In actual application, the specific value of the first duration can be set by technicians in this field according to actual conditions. For example, the first duration can be 1 minute, 2 minutes, 3 minutes, etc., and no specific limitation is made here.

[0072] S128: Broadcast at least one second message again after a second time interval.

[0073] In actual application, the specific value of the second duration can be set by technicians in this field according to actual conditions. For example, the second duration can be 2 minutes, 3 minutes, 5 minutes, etc., and no specific limitation is made here.

[0074] Specifically, in the message forwarding method provided in the embodiment of the present application, when the first device receives the heartbeat signal of at least one third device, that is, when the first device perceives that there is at least one third device in its surrounding environment, the first device broadcasts at least one second message in the queue of messages to be forwarded and continues for the first duration. After the first duration, the first device stops broadcasting at least one second message in the queue of messages to be forwarded, and starts a timer of the second duration, and after the interval of the second duration, that is, after the timer is timed out, if there is still at least one third device in the surrounding environment, the first device broadcasts at least one second message in the queue of messages to be forwarded again and continues for the first duration. This cycle is repeated, so that the first device can intermittently broadcast at least one second message in the queue of messages to be forwarded according to a period, wherein the first duration corresponds to the time period for sending messages in each cycle, and the second duration corresponds to the time period for stopping sending messages in each cycle. In this way, controlling the relay device to intermittently broadcast forwarding messages can reduce the power consumption of the relay device and improve the endurance of the relay device, so that the relay device can forward messages to more devices and increase the diffusion range of messages in a networkless environment.

[0075] In the above-mentioned embodiment provided by the present application, in the process of broadcasting at least one second message in the queue of messages to be forwarded, at least one second message in the queue of messages to be forwarded is broadcast for a first duration; at least one second message is broadcast again after an interval of a second duration, so as to intermittently broadcast at least one second message in the queue of messages to be forwarded according to a period; wherein the first duration corresponds to the time period for sending messages in each cycle, and the second duration corresponds to the time period for stopping sending messages in each cycle. In this way, controlling the relay device to intermittently broadcast forwarding messages can reduce the power consumption of the relay device and improve the endurance of the relay device, thereby enabling the relay device to forward messages to more devices and improve the diffusion range of messages in a network-free environment.

[0076] In the embodiment of the present application, the heartbeat signal includes the screen display status of the third device, and the message forwarding method may further include the following S130 and / or S132:

[0077] S130: When the heartbeat signal of the third device indicates that the screen display state of the third device is switched from the screen-off state to the screen-on state, broadcast at least one second message in the queue of messages to be forwarded.

[0078] The heartbeat signal includes the screen display status of the third device.

[0079] Specifically, in the message forwarding method provided in an embodiment of the present application, when the heartbeat signal received by the first device indicates that the screen display state of the third device has switched from the off state to the on state, it means that the third device is being operated. At this time, the first device immediately broadcasts at least one second message in the message queue to be forwarded to send at least one second message to the third device, so that the person operating the third device can read the second message in time.

[0080] S132: When a heartbeat signal from a fourth device is received, broadcast at least one second message in the queue of messages to be forwarded.

[0081] The fourth device is different from the first device, the second device and the third device. The fourth device is an electronic device that can forward messages as a relay device in a networkless environment.

[0082] Specifically, in the message forwarding method provided in the embodiment of the present application, when the first device receives the heartbeat signal of the fourth device other than the first device, the second device and the third device, it indicates that a new electronic device, namely the fourth device, has entered the communication range of the first device. At this time, the first device immediately broadcasts at least one second message in the queue of messages to be forwarded, so as to send at least one second message to the fourth device in time before the fourth device leaves the communication range of the first device, thereby increasing the diffusion range of the second message and improving the probability of the second message being read.

[0083] In the above embodiment provided by the present application, the heartbeat signal includes the screen display state of the third device. When the heartbeat signal of the third device indicates that the screen display state of the third device is switched from the off-screen state to the on-screen state, at least one second message in the queue of messages to be forwarded is broadcast; and / or, when the heartbeat signal of the fourth device is received, at least one second message in the queue of messages to be forwarded is broadcast. In this way, the probability of the message to be forwarded being read is increased, and the diffusion range of the message to be forwarded is increased.

[0084] In summary, if Figure 2As shown, taking the preset value of 1 as an example, the message forwarding method provided in the embodiment of the present application may specifically include the following S202 to S224:

[0085] S202: Receive a first message from a second device.

[0086] S204: Determine: the first message after removing the first field has been received. If so, end the process. If not, execute S206.

[0087] S206: Determine: whether the value of the first field of the first message is greater than 1, if so, execute S208, if not, end the process.

[0088] S208: Determine: if there are historical messages sent by the target device in the message queue to be forwarded, if so, execute S210, if not, execute S212.

[0089] S210: Determine the one with the larger value of the second field in the first message and the historical message as the second message, reduce the value of the first field of the second message by 1, and save the second message to the queue of messages to be forwarded.

[0090] S212: After reducing the value of the first field of the first message by 1, the first message is saved as the second message in the queue of messages to be forwarded.

[0091] S214: Determine: There is a third device nearby, if yes, execute S216, if not, end the process.

[0092] S216: Forward at least one second message in the to-be-forwarded message queue, and continue for a first duration.

[0093] S218: After the first duration, stop forwarding the second message and set a timer for a second duration.

[0094] S220: The timer expires.

[0095] S222: Receive the heartbeat signal of the fourth device.

[0096] S224: It is detected that the third device changes from a screen-off state to a screen-on state.

[0097] After S220 is executed, if there is still a third device around, S216 is continued to be executed, and S216 is also executed after S222 and S224.

[0098] In this way, the embodiment of the present application provides a message forwarding method, which can relay messages from other devices with the help of surrounding devices (such as electronic devices of people in need, passers-by, and rescuers) in a network-free environment, and can also take into account the battery life of the relay device, avoid invalid forwarding of messages, increase the transmission distance and expansion range of messages in a network-free environment, and improve the probability of message reading.

[0099] The message forwarding method provided in the embodiment of the present application can be executed by a message forwarding device. In the embodiment of the present application, the message forwarding device provided in the embodiment of the present application is described by taking the message forwarding device executing the above message forwarding method as an example.

[0100] like Figure 3 As shown, an embodiment of the present application provides a message forwarding device 300, which is applied to a first device. The message forwarding device 300 may include the following communication unit 302 and processing unit 304.

[0101] The communication unit 302 is configured to receive a first message sent by a second device;

[0102] The processing unit 304 is configured to update the queue of messages to be forwarded according to the first message to obtain at least one second message when the first device has not processed the first message;

[0103] The communication unit 302 is further configured to broadcast at least one second message in the queue of messages to be forwarded upon receiving a heartbeat signal from at least one third device.

[0104] The message forwarding device 300 provided in the embodiment of the present application is applied to the first device, and the first device receives the first message sent by the second device; when the first device has not processed the first message, the queue of messages to be forwarded is updated according to the first message to obtain at least one second message; when the heartbeat signal of at least one third device is received, at least one second message in the queue of messages to be forwarded is broadcast. Through the above-mentioned message forwarding device 300, the first device is used as a relay device, and after receiving the first message of the second device, when it is perceived that there is a third device other than the second device in the surrounding environment, the first message is forwarded to the third device in the form of broadcasting. In this way, on the one hand, in a networkless environment, a message sent by one device can be forwarded to another device through a relay device, thereby improving the transmission distance and diffusion range of the message in the networkless environment; on the other hand, broadcasting the message only when it is perceived that there are other devices in the surrounding environment can also reduce the power consumption of the relay device, improve the endurance of the relay device, and enable the relay device to forward the message to more devices, further improving the diffusion range of the message in the networkless environment.

[0105] In an embodiment of the present application, after receiving the first message sent by the second device, the processing unit 304 is also used to: obtain the first field in the first message; when the value of the first field is greater than a preset value, determine the processing status of the first message, and the processing status is used to indicate whether the first device has processed the first message; when the value of the first field is less than or equal to the preset value, the first message is no longer forwarded; wherein the first field is used to indicate the number of devices that can forward the first message, and each time the first message is forwarded by a different device, the value of the first field in the first message is reduced by 1.

[0106] In the above embodiment provided by the present application, after receiving the first message sent by the second device, the first field in the first message is obtained; when the value of the first field is greater than the preset value, the processing status of the first message is determined, and the processing status is used to indicate whether the first device has processed the first message; when the value of the first field is less than or equal to the preset value, the first message is no longer forwarded; wherein, the first field is used to indicate the number of devices that can forward the first message, and each time the first message is forwarded by a different device, the value of the first field in the first message is reduced by 1. In this way, by adding the first field to the first message, the number of devices that can forward the first message is limited, and the first message can be prevented from being relayed and forwarded without restriction.

[0107] In an embodiment of the present application, the processing unit 304 is specifically used to: remove the first field in the first message to obtain a third message; if there is a historical message that is consistent with the third message, determine that the first message has been processed; if there is no historical message that is consistent with the third message, determine that the first message has not been processed.

[0108] In the above embodiment provided by the present application, in the process of determining the processing status of the first message, the first field in the first message is removed to obtain the third message; when there is a historical message that is consistent with the third message, it is determined that the first message has been processed; when there is no historical message that is consistent with the third message, it is determined that the first message has not been processed. In this way, it is possible to avoid the first device from repeatedly processing the first message and avoid the first device from processing redundant messages, thereby reducing the power consumption of the relay device and improving the battery life of the relay device.

[0109] In an embodiment of the present application, the message source of the first message is the target device, and the first message includes a second field. The processing unit 304 is specifically used to: obtain the message source of the historical message in the message queue to be forwarded; in the case that there is no historical message whose message source is the target device, after reducing the value of the first field in the first message by 1, save the first message as the second message to the message queue to be forwarded; in the case that there is a historical message whose message source is the target device, determine the larger value of the second field in the first message and the historical message as the second message, after reducing the value of the first field in the second message by 1, save the second message to the message queue to be forwarded; wherein, the second field is used to indicate the update status of the message content carried by the first message, and when the message content of the first message is updated compared with the fourth message sent by the target device last time, the value of the second field of the first message is increased by 1 compared with the value of the second field of the fourth message.

[0110] In the above embodiment provided by the present application, the source of the first message is the target device, the first message includes a second field, and in the process of updating the queue of messages to be forwarded according to the first message, the source of the historical message in the queue of messages to be forwarded is obtained; in the case where there is no historical message whose source is the target device, the value of the first field in the first message is reduced by 1, and the first message is saved as the second message to the queue of messages to be forwarded; in the case where there is a historical message whose source is the target device, the one with the larger value of the second field in the first message and the historical message is determined as the second message, and the value of the first field in the second message is reduced by 1, and the second message is saved to the queue of messages to be forwarded; wherein the second field is used to indicate the update status of the message content carried by the first message, and when the message content of the first message is updated compared with the fourth message sent by the target device last time, the value of the second field of the first message is increased by 1 compared with the value of the second field of the fourth message. In this way, only the latest update messages of different electronic devices are saved in the queue of messages to be forwarded, which can avoid the first device forwarding messages whose message content is invalid, and ensure the accuracy of message content forwarding.

[0111] In an embodiment of the present application, the communication unit 302 is specifically used to: broadcast at least one second message in the queue of messages to be forwarded for a first time period; broadcast at least one second message after an interval of a second time period, so as to intermittently broadcast at least one second message in the queue of messages to be forwarded according to a period; wherein the first time period corresponds to a time period for sending messages in each cycle, and the second time period corresponds to a time period for stopping sending messages in each cycle.

[0112] In the above-mentioned embodiment provided by the present application, in the process of broadcasting at least one second message in the queue of messages to be forwarded, at least one second message in the queue of messages to be forwarded is broadcast for a first duration; at least one second message is broadcast again after an interval of a second duration, so as to intermittently broadcast at least one second message in the queue of messages to be forwarded according to a period; wherein the first duration corresponds to the time period for sending messages in each cycle, and the second duration corresponds to the time period for stopping sending messages in each cycle. In this way, controlling the relay device to intermittently broadcast forwarding messages can reduce the power consumption of the relay device and improve the endurance of the relay device, thereby enabling the relay device to forward messages to more devices and improve the diffusion range of messages in a network-free environment.

[0113] In an embodiment of the present application, the heartbeat signal includes the screen display status of the third device, and the communication unit 302 is also used to: when the heartbeat signal of the third device indicates that the screen display status of the third device is switched from the off state to the on state, broadcast at least one second message in the message queue to be forwarded; and / or, when the heartbeat signal of the fourth device is received, broadcast at least one second message in the message queue to be forwarded.
