The system includes a multi-standard access network device and a coupling processing device that are connected to each other, and the above method includes:

S101. The coupling processing device acquires a downlink radio frequency signal of the first standard sent by the access network device of the first standard.

Wherein, when the access network device of the first mode sends downlink data to the terminal device through the downlink channel, it can send the downlink radio frequency signal of the first mode to the outside through the antenna, so that the terminal device of the first mode in the coverage area can receive the above downlink data.

In general, the power of the downlink radio frequency signal received by the coupling processing device through antenna coupling is low, and it is easy to receive spurious signals in space. Therefore, the coupling processing device can filter out the spurious signals through a filter, and then pass the low frequency signal. The noise amplification channel performs low-noise amplification on the received downlink radio frequency signal, so that the power range of the amplified downlink radio frequency signal can meet the requirements of baseband conversion processing. Coupling and receiving downlink radio frequency signals through wireless connection can make it possible to realize the coverage of the first-standard network in the area to be networked when establishing a new generation of network equipment in the blind area not covered by the existing first-standard network, without the need to renew Establish a new first-standard network.

The coupling port of the network device is connected to couple and receive the above-mentioned downlink radio frequency signal. When the power of the downlink radio frequency signal received by the coupling is large, the coupling processing device can increase the link attenuation to reduce the power of the downlink radio frequency signal, so that the power range of the attenuated downlink radio frequency signal can meet the requirements of baseband conversion processing.

Specifically, the coupling processing device may send the uplink radio frequency signal to the access network device of the first standard through a wireless connection, or may send it through a wired connection, which is not limited here.

In the above-mentioned multi-standard networking method, the coupling processing device obtains the downlink radio frequency signal of the first standard sent by the access network device of the first standard, performs baseband conversion on the downlink radio frequency signal, and sends the obtained downlink baseband signal of the first standard to the multi-standard The access network equipment converts the downlink baseband signal through the multi-standard access network equipment to the terminal equipment after radio frequency conversion; or, the coupling processing equipment receives the uplink baseband signal of the first standard sent by the multi-standard access network equipment, and responds to the uplink After the baseband signal is converted, the obtained uplink radio frequency signal of the first standard is sent to the access network device of the first standard. Since the coupling processing device obtains the downlink radio frequency signal of the first standard, and then sends the downlink baseband signal of the first standard obtained after baseband conversion to the multi-standard access network device, the multi-standard access network device can transmit the downlink baseband signal to the radio frequency. After the conversion, it is sent to the terminal device, or receives the uplink baseband signal sent by the multi-standard access network device, and then sends the obtained uplink radio frequency signal of the first standard to the first standard access network device; In the case of network access equipment, the multiplexing of the existing access network equipment of the first standard is realized through the coupling processing equipment, which enhances the network coverage of the first standard and reduces the networking cost.
