Embodiment two

Embodiment 2 considers that the microwave communication node pairs are peer-to-peer, and the microwave communication works in the FDD mode. The master and slave nodes are not configured before the system starts, so each microwave communication node may actively initiate capability negotiation.

After the microwave communication nodes 1 and 2 are powered on, the system parameters (including its receiving/transmitting carrier frequency and bandwidth) are loaded first, and the system is initialized. Then microwave communication nodes 1 and 2 continuously transmit synchronization frames containing capability negotiation request (SCN-REQ) messages on the transmission carrier frequency.

Assuming that microwave communication node 1 is powered on earlier, as shown in FIG. 4 , the microwave communication node sends an SCN-REQ message on the sending carrier frequency, while trying to synchronize on the receiving carrier frequency and receiving a Capability Negotiation Response (SCN-RSP) message. The microwave communication node 1 continues to send the synchronization frame containing the SCN-REQ message until the microwave communication node 1 receives the SCN-RSP message.

The microwave communication node 2 is powered on later than the microwave communication node 2, and the microwave communication node 2 tries to receive the synchronization frame on the receiving carrier frequency while sending the SCN-REQ message at the sending end. If the microwave communication node 2 first successfully receives the synchronization frame sent by the microwave communication node 1, and parses out the SCN-REQ message contained in the synchronization frame, then the microwave communication node 2 continues to judge whether it supports the system configuration in the SCN-REQ message, and sends The system capability information jointly supported by the two is returned to the microwave communication node 1 through the SCN-RSP message, and then starts to wait for the capability negotiation acknowledgment (SCN-ACK) message.

At the same time, the transmitting end of the microwave communication node 2 sends the SCN-ACK message to the microwave communication node 1. Similarly, the SCN-ACK message may be continuously sent multiple times, and the specific number of sending times is initially configured by the system. After sending the SCN-ACK message, the microwave communication node 2 starts to send normal frames. At this time, the microwave communication node 2 completes the synchronization process required for normal sending and receiving of normal frames.

If microwave communication node 1 and microwave communication node 2 receive the synchronization frame sent by the peer microwave communication node at the same time, and parse out the SCN-REQ message contained in the synchronization frame, then microwave communication node 1 and microwave communication node 2 continue to judge whether to support SCN - the system configuration in the REQ message, and return the system capability information jointly supported by the two to the peer microwave communication node through the SCN-RSP message. Similarly, the synchronization frame containing the SCN-RSP message is continuously sent by the microwave communication node 1 and the microwave communication node 2 .

Embodiment Four

Embodiment 4 considers that the microwave communication node pairs are peer-to-peer, and the microwave communication works in the FDD mode. The master and slave nodes are not configured before the system starts, so each microwave communication node may actively initiate capability negotiation.

After the microwave communication node 1 and the microwave communication node 2 are powered on, they both start to continuously send SCN-REQ messages on the sending carrier frequency. At the same time, microwave communication node 1 and microwave communication node 2 both try to synchronize on the receiving carrier frequency and receive a synchronization frame containing capability negotiation information.

Similarly, the synchronization frame containing the SCN-RSP message is continuously sent by the microwave communication node 1 and the microwave communication node 2 .

If the microwave communication node 2 receives the SCN-RSP message sent by the microwave communication node 1 earlier, the microwave communication node 2 analyzes the system capabilities supported by both, and then sends the SCN-ACK message. To ensure reliability, the SCN-ACK The message may be sent multiple times in a row, and the specific number of sending times is initially configured by the system. After sending the SCN-ACK message, microwave communication node 2 starts to send normal frames.

If the microwave communication node 1 correctly receives the SCN-ACK message, the microwave communication node 1 can start to normally receive the normal frame sent from the microwave communication node 2 . At the same time, the transmitter of microwave communication node 1 sends an SCN-ACK message to microwave communication node 2.

Embodiment five

Embodiment 5 considers that the microwave communication node pairs are peer-to-peer, and the microwave communication works in the FDD mode. The master and slave nodes are not configured before the system starts, so each microwave communication node may actively initiate capability negotiation. When microwave communication node 1 and microwave communication node 2 perform synchronization and capability negotiation, microwave communication node 1 starts to send SCN-ACK messages and ordinary frames after a series of previous signaling interactions, and waits for the SCN-ACK message sent by the other node at the same time. State, FIG. 7 is a flowchart of synchronization and capability negotiation in Scenario 4 when a microwave communication node is started or restarted or out of synchronization according to an embodiment of the present invention, as shown in FIG. 7 . At this time, the microwave communication node 2 was suddenly powered off, and then powered on again immediately. After restarting, the microwave communication node 2 sent the SCN-REQ message on the sending carrier frequency, while trying to synchronize on the receiving carrier frequency and receive the ability Synchronization frame for negotiating messages.

If the microwave communication node 2 correctly parses out the synchronization frame containing the SCN-ACK message, the microwave communication node 2 directly ignores the information and continues to send the SCN-REQ message.

When the microwave communication node 1 finds that it cannot be further synchronized with the microwave communication node during the process of continuously sending ordinary frames, the microwave communication node 1 enters an out-of-synchronization state and starts to continuously send SCN-REQ messages. If the microwave communication node 1 successfully receives the synchronization frame sent by the microwave communication node 2 directly after determining the out-of-synchronization or before determining the out-of-synchronization, and parses out the SCN-REQ message contained in the synchronization frame, then the microwave communication node 1 continues It is judged whether the system configuration in the SCN-REQ message is supported, and the system capability information supported by both is returned to the microwave communication node 2 through the SCN-RSP message. Microwave communication node 1 continuously sends synchronization frames containing SCN-RSP messages.

If the microwave communication node 2 receives the SCN-RSP message correctly, the microwave communication node 2 analyzes the system capabilities supported by both, and then sends the SCN-ACK message. In order to ensure reliability, the SCN-ACK message may be sent multiple times continuously. The specific sending times are initially configured by the system. After sending the SCN-ACK message, microwave communication node 2 starts to send normal frames.

If the microwave communication node 1 correctly receives the SCN-ACK message sent by the microwave communication node 2, the microwave communication node 1 can start to normally receive the normal frame sent from the microwave communication node 2. At the same time, the transmitter of microwave communication node 1 sends an SCN-ACK message to microwave communication node 2. Similarly, the SCN-ACK message may be sent multiple times continuously, and the specific number of sending times is initially configured by the system. After sending the SCN-ACK message, microwave communication node 1 starts to send normal frames, and at this time, microwave communication node 2 completes the synchronization process required for normal sending and receiving of normal frames.

If the microwave communication node 2 correctly receives the SCN-ACK message, then the microwave communication node 2 can start to normally receive the normal frame sent from the microwave communication node 1, and at this time, the microwave communication node 1 has also completed the normal sending and receiving of the normal frame. Synchronization process.

Embodiment six

Embodiment 6 considers the situation that microwave communication node pairs are peer-to-peer. The master and slave nodes are not configured before the system starts, so each microwave communication node may actively initiate capability negotiation. Microwave communication may be TDD or work in FDD mode. The difference from the second embodiment is that the microwave communication node does not send a synchronization frame, but only realizes synchronization through the preconfigured preamble of a normal frame.

After the microwave communication node is started or restarted, the system parameters are first loaded to initialize the system. Then the microwave communication node sends a normal frame including a system capability negotiation request SCN-REQ message on the sending carrier frequency. The SCN-REQ message includes information such as configuration change count, encryption and decryption configuration, automatic modulation and coding configuration, and packet header compression configuration. The configuration change count is used to indicate whether the system capability has changed. If the system capability of the microwave communication node changes, the configuration change count can be marked by adding 1. If the specific capability parameters do not change in two consecutive system capability negotiations, the configuration change count remains unchanged. After the microwave communication node sends the SCN-REQ message, it tries to synchronize on the receiving carrier frequency and receives the system capability negotiation response SCN-RSP message.

After the peer-to-peer microwave communication node is started or restarted, it also loads system parameters first, initializes the system, and then sends a normal frame containing a system capability negotiation request SCN-REQ message. If the peer-to-peer microwave communication node monitors the transmission of the microwave communication node at the same time, the peer-to-peer microwave communication node tries to complete the synchronization with the microwave communication node through the preamble and receives the normal frame containing the SCN-REQ management message sent by the microwave communication node. If the peer-to-peer microwave communication node successfully completes receiving synchronization and parses the SCN-REQ message contained in the common frame, the peer-to-peer microwave communication node judges whether to support the capability configuration in the SCN-REQ message. If the system capabilities supported by the two are exactly the same, Then the configuration change count in the SCN-RSP message follows the configuration change count in the SCN-REQ message, otherwise, find out the system capabilities supported by both, and add one to the configuration change count in the SCN-REQ message , and then return the configuration change count and capability information to the microwave communication node through the SCN-RSP message, and start waiting for the system capability negotiation to confirm the SCN-ACK message.

The microwave communication node tries to complete the synchronization with the peer microwave communication node through the preamble and receives the normal frame containing the SCN-RSP management message sent by the microwave communication node. If the microwave communication node successfully completes receiving synchronization and parses out the SCN-RSP message included in the common frame, the microwave communication node determines communication parameters and sends an SCN-ACK message.

If the peer-to-peer microwave communication node receives the SCN-ACK message correctly, the microwave communication node and the peer-to-peer microwave communication node have completed two-way synchronization and capability negotiation, and can start sending and receiving data frames normally.

Embodiment seven

Embodiment 7 also considers the situation that the pairs of microwave communication nodes are peer-to-peer. The master and slave nodes are not configured before the system starts, so each microwave communication node may actively initiate capability negotiation. Microwave communication may be TDD or work in FDD mode. The difference from Embodiment 2 is that the microwave communication node is not in the start-up or restart state, but finds that it is out of synchronization with the peer microwave node during system operation.

If the modulation and coding mode of the microwave communication node pair has been reduced to QPSK 1/2 during the system operation, but the bit error rate still exceeds the predetermined threshold, the microwave communication node believes that the system is out of synchronization, such as microwave communication node 1 and microwave communication node 2 During the communication process, microwave communication node 2 finds that it cannot synchronize with microwave communication node 1, then microwave communication node 2 enters the capability negotiation stage, and immediately starts sending the synchronization frame after sending the current frame. The out-of-synchronization situation is the same as when the system is initially started or restarted. The microwave communication node 2 sends a synchronization frame containing the SCN-REQ message on the sending carrier frequency, and tries to synchronize and receives a synchronization frame containing the SCN-RSP message on the receiving carrier frequency. The microwave communication node 2 continues to send the synchronization frame containing the SCN-REQ message until the microwave communication node 1 receives the SCN-RSP message.

Corresponding microwave communication node 1 thinks that what microwave communication node 2 sends is still an ordinary frame, and parses the synchronization frame in the form of an ordinary frame, resulting in a parsing error. After several consecutive frames, it will think that it cannot be synchronized with microwave communication node 2 and enter into synchronization and capacity negotiation phase. At this time, the microwave communication node 1 stops sending the normal frame, and immediately sends the synchronization frame including the SCN-REQ message. If the microwave communication node 1 can receive the SCN-REQ message sent by the microwave communication node 2, the microwave communication node 1 returns the system capability information supported by both to the microwave communication node 2 through a synchronization frame containing the SCN-RSP message, and then Start waiting for the SCN-ACK message.

The microwave communication node 1 continues to send the synchronization frame containing the SCN-RSP message until the microwave communication node 1 receives the SCN-ACK message. If the microwave communication node 1 correctly receives the SCN-ACK message, then the microwave communication node 1 sends the SCN-ACK message to the microwave communication node 2. At this time, the microwave communication node 1 has completed the synchronization and synchronization from the microwave communication node 2 to the microwave communication node 1. After capability negotiation, the microwave communication node 1 can start to send and receive ordinary frames.

If the microwave communication node 2 receives the SCN-RSP message, it sends a synchronization frame containing the SCN-ACK message to the microwave communication node 1, and then restarts the sending of ordinary frames. At the same time, the microwave communication node 2 waits for the microwave communication node 1 to send If the microwave communication node 2 correctly receives the SCN-ACK message, the synchronization and capability negotiation from the microwave communication node 1 to the microwave communication node 2 is completed, and the microwave communication node 2 can start to receive ordinary frames.

Embodiment eight

The eighth embodiment considers the situation that the pairs of microwave communication nodes are not equal. The master-slave nodes are configured before the system starts, and only the microwave communication master node can initiate capability negotiation. Microwave communication may be TDD or work in FDD mode.

After the microwave communication master node starts or restarts, it first loads the system parameters, initializes the system, and then sends a synchronization frame containing the system capability negotiation request SCN-REQ message on the carrier frequency. After the microwave communication node sends the SCN-REQ message, it tries to synchronize on the receiving carrier frequency and receives the system capability negotiation response SCN-RSP message.

After the microwave communication slave node is started or restarted, it also loads the system parameters first, initializes the system, and then tries to receive the synchronization frame sent by the microwave communication master node, and synchronizes with the microwave communication node through the synchronization frame. Figure 7 is an example according to an embodiment of the present invention The flow chart of synchronization and capability negotiation in Scenario 4 when the microwave communication node of the microwave communication node is started or restarted or is out of synchronization is shown in FIG. 7 . If the microwave communication slave node successfully completes the synchronization and parses out that the synchronization frame contains the SCN-REQ message, the microwave communication slave node judges whether it supports the capability configuration in the SCN-REQ message. If the system capabilities supported by the two are exactly the same, the SCN-REQ The configuration change count in the RSP message follows the configuration change count in the SCN-REQ message, otherwise, find out the system capabilities supported by both, add one to the configuration change count in the SCN-REQ message, and then pass The SCN-RSP message returns the configuration change count and commonly supported capability information to the microwave communication master node, and starts to wait for the system capability negotiation to confirm the SCN-ACK message.

The microwave communication master node tries to complete the synchronization with the microwave communication slave node through the synchronization frame and parses the SCN-RSP management message contained in the synchronization frame sent by the microwave communication slave node. If the microwave communication master node successfully completes receiving synchronization and parses out the SCN-RSP message, the microwave communication master node determines communication parameters and sends an SCN-ACK message.

If the microwave communication slave node correctly receives the SCN-ACK message, the microwave communication master node and the microwave communication slave node have completed two-way synchronization and capability negotiation, and can start sending and receiving data frames normally.

In addition, if the microwave communication node finds that it is out of synchronization during system operation, it can also refer to the above process to complete the synchronization and capability negotiation.

It should be noted that FIG. 9 is a state machine for microwave communication master node synchronization and capability negotiation according to an embodiment of the present invention. In this embodiment, the microwave communication master node synchronization and capability negotiation state machine is shown in FIG. 9 . FIG. 10 is a state machine for microwave communication slave node synchronization and capability negotiation according to an embodiment of the present invention. The state machine for microwave communication slave node synchronization and capability negotiation in this embodiment is shown in FIG. 10 .

The master-slave nodes are configured before the system starts, and only the microwave communication master node can initiate capability negotiation. Microwave communication may be TDD or work in FDD mode. However, different from the sixth embodiment, the system does not send a synchronization frame, and completes synchronization only through the preamble of a normal frame including SCN-REQ and SCN-RSP messages.
