[0103] In some embodiments, the terminal device may be a passive terminal device or a low-power terminal device (for example, a low-power ambient IoT device or a passive ambient IoT device). In order to reduce the power consumption and complexity of the terminal device, the communication distance that the terminal device can support may be less than a distance threshold, which may be any value between 1 meter and 1000 meters, for example, 10 meters, 50 meters, 100 meters, or 200 meters.

[0104] When the communication distance supported by the terminal device is less than the distance between the terminal device and the network device, the terminal device can register with the network device through the relay device, and can also communicate with the network device through the relay device, thereby solving the problem that the terminal device cannot register or communicate due to distance reasons.

[0105] Using this method, a terminal device can register via a relay device. The relay device can forward wireless signals between the terminal device and network devices, which can be used to register the terminal device. The terminal device can be an ambient IoT device.

[0157] It should be noted that the first message may carry any information or signal, such as synchronization information, system information, trigger signal or other registration information, etc. Similarly, the second message may also carry any of the above information or signals.

[0158] In some embodiments, the network device sends a second message, and after receiving the second message, the relay device forwards the first message to the terminal device (the content of the first message is exactly the same as the second message). Both the second message and the first message can be received by the terminal device. At this time, the terminal device can determine that the second message and the first message are duplicate messages.

[0159] It should be noted that the above-mentioned repeated messages may be messages with the same message type, message identifier and message content. The message type may be used to indicate the information or signal carried in the message, and the message identifier may be used to distinguish messages of the same message type.

[0160] For example, the repeated messages may be messages of the same message type, message identifiers may be the same or different, and message contents may also be the same or different. For another example, the repeated messages may be messages of the same message identifier, message types may be the same or different, and message contents may also be the same or different. For another example, the repeated messages may be messages of the same message content, message types may be the same or different, and message identifiers may also be the same or different. For another example, the repeated messages may be messages of the same message type and message identifier, and message contents may also be the same or different.

[0161] There are many ways for the terminal device to determine that the second message is a duplicate of the first message. For example:

[0162] For example, when the second message and the first message have the same message type, it can be determined that the second message and the first message are duplicate messages.

[0163] For another example, if the second message has the same message identifier as the first message, it can be determined that the second message and the first message are duplicate messages, wherein the message identifier is used to distinguish different messages.

[0164] For another example, when the second message and the first message have the same message type and the second message and the first message also have the same message identifier, it can be determined that the second message and the first message are duplicate messages.

[0165] For another example, if the second message and the first message are of the same message type and the time difference between the reception of the second message and the first message is less than or equal to a preset time difference threshold, the second message and the first message can be determined to be duplicate messages. The preset time difference threshold can be any preset time, such as 10 milliseconds, 100 milliseconds, or 1 second.

[0166] For another example, when the message identifiers of the first message and the second message are the same and the reception time difference between the second message and the first message is less than or equal to the preset time difference threshold, it can be determined that the second message and the first message are duplicate messages.

[0167] For another example, when the message type and message identifier of the first message and the second message are the same, and the reception time difference between the second message and the first message is less than or equal to the preset time difference threshold, it can be determined that the second message and the first message are duplicate messages.

[0168] S704: The terminal device discards one of the repeated messages.

[0169] In some embodiments, the discarded message may be a random message. For example, the terminal device may randomly discard one message from the first message and the second message and retain one message.

[0170] In other embodiments, the discarded message may be the first message sent by the relay device. For example, the terminal device may discard the first message sent by the relay device and retain the second message sent by the network device.

[0171] It should be noted that, since the relay device can forward the message sent by the network device, when the terminal device receives a duplicate message, it can take the message sent by the network device as the basis and discard the message sent by the relay device.

[0172] In some other embodiments, the discarded message may be the second message sent by the network device. For example, the terminal device may discard the second message sent by the network device and retain the first message sent by the relay device.

[0173] In some other embodiments, the discarded message may be a message received earlier than the non-discarded message. In other words, the discarded message may be received earlier than the non-discarded message. For example, the terminal device may discard the earliest received message and retain the latest received message.

[0174] Optionally, the terminal device may also perform an action corresponding to the message according to the retained message, such as sending a feedback signal or registering.

[0175] It should be noted that, unless there is any contradiction, the embodiment shown in FIG. 7 can be combined with the aforementioned embodiments or implementation methods of the present disclosure and their various optional solutions, which will not be described in detail here.

[0176] In this way, when receiving duplicate messages, the terminal device can choose to discard one of the messages according to different strategies, thereby improving the reliability of terminal device communication.

[0177] In some embodiments of the present disclosure, a terminal device may receive a third message and a fourth message sent by a first device, determine that the third message and the fourth message are duplicate messages, and discard one of the duplicate messages. The discarded message may be a message received earlier than a message that is not discarded, and the first device may be a relay device or a network device.

[0178] It should also be noted that the duplicate message may be a message with the same message type, message identifier, and message content. The message type may be used to indicate information or signals carried in the message, and the message identifier may be used to distinguish messages of the same message type.

[0179] For example, a network device may periodically send system messages. The network device may send two system messages (e.g., the third message and the fourth message) in succession. However, due to delay or load reasons, the terminal device receives the third message and the fourth message in a relatively short period of time and neither of them is processed. The terminal device may determine that the two received system messages are duplicate messages and discard one of the messages using the above method. In this way, the terminal device may reduce the processing of messages by the terminal device.

[0180] For another example, after the network device sends a system message (the third message), the system information is updated and a new system message (the fourth message) is sent again. The message types sent twice are the same system message type. The terminal device can determine that the two received system messages are duplicate messages based on the message type, and use the above method to discard one of the messages. In this way, the terminal device can reduce the processing of messages.

[0181] The specific manner in which the terminal device determines that the third message and the fourth message are duplicate messages can refer to the manner in which the terminal device determines that the second message and the first message are duplicate messages in the aforementioned embodiment of the present disclosure, which will not be repeated here.

[0182] In this way, when a terminal device receives duplicate messages sent by a relay device or a network device, it can choose to discard one of the messages according to different strategies, thereby improving the reliability of communication of the terminal device.

[0187] In some embodiments, the terminal device may be a passive terminal device or a low-power terminal device (for example, a low-power ambient IoT device or a passive ambient IoT device).

[0216] The relay device receives a termination signaling sent by the network device, wherein the termination signaling is used to instruct the relay device to end the registration process, or the termination signaling is used to instruct the relay device to disconnect the communication connection with the terminal device.

[0217] In this way, the relay device can register the terminal device through any one or a combination of any two or more of the above steps.

[0218] In some embodiments of the present disclosure, a relay device may send a first message to a terminal device, and a network device may send a second message to the terminal device.

It should be noted that the first message may carry any information or signal, such as synchronization information, system information, a trigger signal, or other registration information. Similarly, the second message may also carry any of the above information or signals.

[0219] For example, the network device sends a second message, and after receiving the second message, the relay device forwards the first message to the terminal device (the content of the first message is exactly the same as the second message).
