In each step of sending and receiving a message, the message may be encrypted and authenticated as required, which will not be described in detail below.

Step 7, RRU1 sends a message to ALD2;

When RRU1 needs to transmit information to ALD1, such as control information to ALD1, although RRU1 is not directly connected to ALD1, RRU1 can send a message to ALD2 through the ZigBee network and request ALD2 to forward the message to ALD1.

Step 8, ALD2 sends a message to ALD1;

After receiving the message sent by RRU1 to ALD1, ALD2 can forward the message to ALD1 according to the network short address.

Step 9, ALD1 returns a message to ALD2;

After ALD1 receives the message sent by RRU1 and forwarded by ALD2, it will reply with a confirmation message and return the message to ALD2.

Step 10, ALD2 returns a message to RRU1;

After ALD2 receives the message returned by ALD1, it can return the message to RRU1 according to the address identifier.

In this way, the data transmission between the ALD1 and the RRU1 can be implemented from steps 7 to 10 .

Step 11, RRU2 sends a message to ALD3;

The RRU2 can directly send a message to the ALD3 through the ZigBee network, and the message can be a control message to the ALD3.

Step 12, ALD3 returns a message to RRU2;

After ALD3 receives the message, it can return a confirmation message to RRU2.

This operation can be controlled by a terminal, such as a mobile phone or a PC with a Bluetooth module, or controlled by the ALD or the central processing unit of the base station through software, which is not specifically limited here.

Step 1. RRU1 is connected to ALD2;

By querying the address of ALD2, the Bluetooth adapter module of RRU1 can perform paging and connect with ALD2 through the Bluetooth network. In addition, it can also authenticate through a custom protocol to identify whether the connected node is used for RRU and ALD to transmit data. the wireless communication module, if it is, keep it connected, if not, disconnect it. The authentication step may be performed in the process of establishing the Bluetooth connection, which will not be repeated in this embodiment of the present application.

Step 2. Connect ALD3 and ALD2;

Step 3. Connect ALD1 and ALD2;

Step 4. RRU2 is connected to ALD2;

The process of performing the Bluetooth connection in steps 2 to 4 is similar to that in step 1, and will not be repeated here.

It should be noted that the execution order of step 1 to step 4 is not limited.

Through steps 1 to 4, the 3 ALDs and 2 RRUs in this embodiment realize the Bluetooth networking and can perform data transmission. Due to the large number of nodes, the following data transmission between RRU1 and ALD2, and RRU2 Take the data transmission with ALD1 as an example, please refer to Step 5 and Step 6, and Step 7 to Step 10.

Step 5. RRU1 sends a message to ALD2;

When RRU1 needs to send a control signal to ALD2, it can send a message to ALD2 through an external Bluetooth adapter module. The rate of message transmission can be determined according to the Bluetooth protocol, for example, it can be 1 million bits per second (Mbps).

Step 6. ALD2 returns a message to RRU1;

After ALD2 receives the message sent by RRU1, it can return a message to RRU1 through the built-in Bluetooth module of ALD2.

In this way, steps 5 and 6 can realize data transmission between ALD2 and RRU1.

Step 7. RRU2 sends a message to ALD2;

When RRU2 needs to send the control signal of ALD1 to ALD1, although RRU1 and ALD1 do not directly establish a Bluetooth connection, routing and forwarding can be performed through ALD2. RRU2 sends a message to ALD2, and the message carries the address information of ALD1.

Step 8. ALD2 sends a message to ALD1;

After ALD2 receives the message sent by RRU2 to ALD1, it can forward the message, that is, send the received message to ALD1.

Step 9. ALD1 returns a message to ALD2;

After ALD1 receives the information sent by RRU2 forwarded by ALD2, it can perform corresponding operations according to the control signal and return a confirmation message. Similarly, the message needs to be forwarded by ALD2. Therefore, ALD1 returns a message to ALD2, which carries the address of RRU2. information.

Step 10, ALD2 returns a message to RRU2;

After receiving the return message sent by ALD1, the ALD forwards the message to RRU2.

In this way, steps 7 to 10 can implement data transmission between the ALD1 and the RRU2.

In the method for connecting the RRU and the ALD provided by the embodiments of the present application, the RRU and the ALD can establish a Bluetooth network through a newly added Bluetooth module or a Bluetooth adapter module, and transmit data through the Bluetooth network.
