FIG7 is a flow chart of a registration method according to an exemplary embodiment. The method may be executed by a terminal device in the above communication system. As shown in FIG7 , the method may include:

S701. A terminal device receives a first message sent by a relay device.

S702: The terminal device receives a second message sent by the network device.

S703: The terminal device determines that the second message and the first message are duplicate messages.

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 signal.

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.

It should be noted that the above repeated messages may be messages 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.

For example, the repeated message may be a message with the same message type, the message identifiers may be the same or different, and the message contents may also be the same or different. For another example, the repeated message may be a message with the same message identifier, the message type may be the same or different, and the message contents may also be the same or different. For another example, the repeated message may be a message with the same message content, the message type may be the same or different, and the message identifiers may also be the same or different. For another example, the repeated message may be a message with the same message type and message identifier, and the message contents may also be the same or different.

There are many ways for the terminal device to determine that the second message and the first message are duplicate messages. For example:

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.

For another example, when 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.

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

For another example, when the second message and the first message have the same message type and the reception time difference between 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.

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 a preset time difference threshold, it can be determined that the second message and the first message are duplicate messages.

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

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

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.

In some 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.

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 standard and discard the message sent by the relay device.

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.

In some other embodiments, the discarded message may be a message whose receiving time is earlier than the receiving time of the message that is not discarded. That is, the receiving time of the discarded message may be earlier than the receiving time of the message that is not discarded. For example, the terminal device may discard the earliest received message and retain the latest received message.

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.

It should be noted that, in the absence of 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 schemes, which will not be described in detail here.

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 communication of the terminal device.

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 whose receiving time is earlier than the receiving time of the message that is not discarded, and the first device may be a relay device or a network device.

It should also be noted that the repeated 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.

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) successively. However, due to delay or load reasons, the terminal device may receive the third message and the fourth message in a short period of time and may not process them. The terminal device may determine that the two received system messages are duplicate messages and may discard one of the messages using the above method. In this way, the terminal device may reduce the amount of message processing required by the terminal device.

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 discard one of the messages using the above method. In this way, the terminal device can reduce the message processing required by the terminal device.

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, and will not be repeated here.

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