It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The multi-system networking method provided by the application can be applied to the application environment shown in fig. 1. The multi-system networking system comprises multi-system access network equipment 100 and coupling processing equipment 200 which are connected with each other, wherein the coupling processing equipment 200 is in communication connection with first-system access network equipment 300, and the multi-system access network equipment 100 is in communication connection with terminal equipment 400. The first-standard Access network device 300 and the multi-standard Access network device 100 may be, but not limited to, base station devices of macro base stations, micro base stations, small base stations, and the like, and may support Global System for Mobile communications (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (Long Term Evolution, LTE), fifth-generation Mobile communication technology, network standards appearing in the future, and the like, and are not limited herein. The terminal 200 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, portable wearable devices, and the like. The coupling processing device 200 may be an independent device unit, or may be a component embedded in a multi-system access network device, which is not limited herein.
In an embodiment, as shown in fig. 2, a multi-system networking method is provided, which is described by taking an example that the method is applied to a coupling processing device in a multi-system networking system in fig. 1, where the multi-system networking system includes a multi-system access network device and a coupling processing device that are connected to each other, and the method includes:
s101, the coupling processing equipment acquires a downlink radio frequency signal of a first standard sent by the access network equipment of the first standard.
When the first-standard access network equipment sends downlink data to the terminal equipment through the downlink channel, the downlink radio-frequency signal of the first standard can be sent outwards through the antenna, so that the terminal equipment of the first standard in the coverage area can receive the downlink radio-frequency signal. When multi-system networking is realized in a to-be-networked area, in order to realize multiplexing of first-system access network equipment in the existing network and reduce networking cost, a downlink radio frequency signal of a first system sent by the first-system access network equipment can be acquired through coupling processing equipment.
Specifically, the coupling processing device couples and receives a downlink radio frequency signal of a first standard sent by the access network device of the first standard through wireless connection; and/or the coupling processing device is coupled and receives the downlink radio frequency signal of the first standard sent by the access network device of the first standard through wired connection.
In one scenario, the coupling processing device may include a receiving antenna, and receive the downlink radio frequency signal of the first standard through the receiving antenna in a coupling manner. Generally, the coupling processing device receives a downlink radio frequency signal through antenna coupling with a small power and is easy to receive a stray signal in a space, so that the coupling processing device can filter the stray signal through a filter and then perform low-noise amplification on the received downlink radio frequency signal through a low-noise amplification channel, so that the power range of the amplified downlink radio frequency signal can meet the requirement of baseband conversion processing. The downlink radio frequency signals are coupled and received in a wireless connection mode, so that when a new generation of network equipment is established in a blind area uncovered by the existing first standard network, the coverage of the first standard network is realized in an area to be networked, and a new first standard network does not need to be established again.
In one scenario, the first-standard access network device may output a downlink radio frequency signal through a coupling port; meanwhile, the coupling processing device may include a radio frequency connection port, and be connected to the coupling port of the first system access network device through a radio frequency cable connected to the radio frequency connection port, so as to receive the downlink radio frequency signal in a coupling manner. When the power of the downlink radio-frequency signal received by coupling is larger, the coupling processing equipment can reduce the power of the downlink radio-frequency signal by increasing the link attenuation, so that the power range of the attenuated downlink radio-frequency signal can meet the requirement of baseband conversion processing. In addition, if the power of the downlink radio frequency signal received by the coupling is low, the coupling processing device may also amplify the downlink radio frequency signal.
In another scenario, the coupling processing device may include a receiving antenna and a radio frequency connection port, and may couple and receive the downlink radio frequency signal in a wireless connection mode and a wired connection mode at the same time. Further, the coupling processing device may perform filtering, attenuation, amplification, and other processing on the downlink radio frequency signals received by the wired and wireless couplings respectively through the wired radio frequency processing unit and the wireless radio frequency processing unit.
Specifically, the first-standard access network device may include an access network device of one standard, or may be an access network device of multiple standards. For example, when a 4G network is established on the basis of the existing 2G network and 3G network, the remote processing unit in the multi-mode access network device may simultaneously support the 2G, 3G, and 4G networks, and may receive downlink radio frequency signals sent by the 2G access network device and the 3G access network device through the coupling processing device.
S102, after baseband conversion is carried out on the downlink radio frequency signals, the obtained downlink baseband signals of the first standard are sent to multi-standard access network equipment.
After acquiring the downlink radio frequency signal of the first standard, the coupling processing device may perform baseband conversion on the downlink radio frequency signal to obtain a downlink baseband signal of the first standard.
Specifically, the coupling processing device may perform down-conversion, filtering, and other processing on the downlink radio frequency signal, and then complete analog-to-digital conversion and digital intermediate frequency processing to obtain a downlink baseband signal of the first system. And the coupling processing equipment acquires the downlink baseband signal, so that the multi-system base station equipment processes the downlink baseband signal and sends the processed downlink baseband signal to the terminal equipment of the first system.
Further, when the coupling processing device transmits the obtained downlink baseband signal of the first standard to the multi-standard access network device, the downlink baseband signal of the first standard may be transmitted through a Common Public Radio Interface (CPRI), or may be transmitted through an Open Base Station Architecture (Open Base Station Architecture) OBSAI (OBSAI), where the transmission manner is not limited herein. For example, when the coupling processing device sends the downlink baseband signal through the CPRI, the sampling rate may be adjusted to match the CPRI sending requirement.
And S103, performing radio frequency conversion on the downlink baseband signal through the multi-system access network equipment and then sending the downlink baseband signal to the terminal equipment.
The multi-system access network equipment can simultaneously support the transmission of signals of multiple systems. The coupling processing equipment can carry out radio frequency conversion on the downlink baseband signal of the first standard through the multi-standard access network equipment and then send the downlink baseband signal of the first standard to the terminal equipment of the first standard; meanwhile, the multi-system access network equipment can also realize the signal processing and transmission of a new network system, and realize the fusion of multiple network systems.
Specifically, when the multi-system access network device performs radio frequency conversion on a downlink baseband signal, the multi-system access network device may perform up-conversion and filtering on the baseband signal, then perform radio frequency filtering and linear power amplification, and send the radio frequency filtered signal to the output filter, and send the radio frequency filtered signal to the terminal device through the antenna feeder.
For the uplink channel, in the area to be networked, the terminal device of the first standard may send an uplink signal to the access network device of the multiple standards, process the uplink signal through the access network device of the multiple standards and the coupling processing device, send the uplink signal carrying the terminal device to the access network device of the first standard, process the uplink signal of the terminal device through the access network device of the first standard, and then transmit the uplink signal back to the core network device of the first standard.
The specific process of the multi-standard access network equipment and the coupling processing equipment for processing the uplink signal is as follows:
s104, the coupling processing equipment receives the uplink baseband signal of the first standard sent by the multi-standard access network equipment.
After receiving the uplink signal sent by the terminal device of the first standard, the multi-standard access network device may perform low-noise amplification, filtering, down-conversion, and the like on the uplink signal, and then obtain an uplink baseband signal of the first standard after completing analog-to-digital conversion and digital intermediate frequency processing.
Further, the multi-system access network device may send the uplink baseband signal to the coupling processing device, and specifically, the coupling processing device may receive the uplink baseband signal through the CPRI, or may receive the uplink baseband signal through the OBSAI, which is not limited herein.
And S105, converting the uplink baseband signal, and sending the obtained uplink radio frequency signal of the first standard to the access network equipment of the first standard.
Further, the coupling processing device may perform conversion on the received uplink baseband signal to an uplink radio frequency signal, and then send the uplink radio frequency signal to the first standard access network device; the frequency of the uplink radio frequency signal may be the same as the frequency of the uplink signal sent by the terminal device. The first standard access network equipment can receive and process the uplink radio frequency signal by carrying the uplink data of the terminal equipment through the uplink radio frequency signal.
Specifically, the coupling processing device may send the uplink radio frequency signal to the first standard access network device in a wireless connection manner, or may send the uplink radio frequency signal in a wired connection manner, which is not limited herein.
In the multi-system networking method, the coupling processing device acquires a downlink radio frequency signal of a first system sent by the access network device of the first system, performs baseband conversion on the downlink radio frequency signal, sends the acquired downlink baseband signal of the first system to the multi-system access network device, performs radio frequency conversion on the downlink baseband signal through the multi-system access network device, and sends the downlink baseband signal to the terminal device; or, the coupling processing device receives an uplink baseband signal of a first standard sent by the multi-standard access network device, converts the uplink baseband signal, and sends the obtained uplink radio frequency signal of the first standard to the first-standard access network device. The coupling processing equipment acquires a downlink radio frequency signal of a first standard, and then transmits the downlink baseband signal of the first standard acquired after baseband conversion to the multi-standard access network equipment, so that the multi-standard access network equipment can perform radio frequency conversion on the downlink baseband signal and then transmit the downlink baseband signal to the terminal equipment, or receive an uplink baseband signal transmitted by the multi-standard access network equipment, and then transmit the acquired uplink radio frequency signal of the first standard to the first-standard access network equipment; under the condition that the first system access network equipment is not added, the multiplexing of the existing first system access network equipment is realized through the coupling processing equipment, the network coverage of the first system is enhanced, and the networking cost is reduced.
In one embodiment, the present invention relates to a method for transmitting downlink baseband signals to a multi-system access network device by a coupling processing device. On the basis of the above embodiment, the multi-system access network device may include a baseband processing unit of the second system, a convergence unit, and a multi-system remote radio frequency unit. As shown in fig. 3, the coupling processing device may send the downlink baseband signal of the first standard to a baseband processing unit of a second standard in the multi-standard access network device, or a convergence unit connected to the baseband processing unit of the second standard.
The baseband processing unit of the second standard may be configured to implement baseband signal processing of the second standard, and the network of the second standard may be a new-generation communication network, an LTE network, or a 5G network. When a multi-system access network device is newly built in a to-be-networked area, a baseband processing unit in the multi-system access network device can be only used for processing a baseband signal of a second system, meanwhile, a coupling processing device is fused with a first system access network device, and the baseband signal processing of a first system is realized by multiplexing a first system baseband processing unit connected with the first system access network device, so that the networking cost is reduced.
The baseband processing unit may return data to the core network of the second system through a network cable or an optical fiber, for example, may be connected to a serving gateway S-GW in the core network device of the second system through an SI-U interface, and connected to a mobility Management device (MME) in the core network device of the second system through an S1-MME interface. In addition, the baseband processing unit can also realize the functions of parameter configuration, software upgrading, carrier tracking and the like of each device in the multi-system networking system. The base band processing unit can also have an automatic station opening function, can realize automatic station opening of a multi-system networking system, and improves the station opening efficiency.
After receiving the downlink baseband signal of the first standard, the baseband processing unit may perform forwarding processing on the downlink baseband signal instead of performing baseband processing on the downlink baseband signal of the first standard. For example, when the baseband processing unit is connected to a multi-system remote rf unit, the baseband processing unit may forward the downlink baseband signal to the multi-system remote rf unit; when the baseband processing unit is connected to the multiple multi-system remote radio frequency units, the baseband processing unit may distribute the downlink baseband signal and send the downlink baseband signal to the multiple multi-system remote radio frequency units.
In the multi-system access network device, the baseband processing unit may also be connected to the convergence unit. The convergence unit can receive the downlink baseband signals sent by the baseband processing unit and distribute the downlink baseband signals to a plurality of multi-system remote radio frequency units connected with the convergence unit. The convergence unit and the baseband processing unit can be connected through optical fibers to support remote equipment; in the multi-system access network equipment, the cascade connection of a plurality of convergence units can be realized, and the multi-system remote radio frequency unit is pulled away to a station position through the plurality of convergence units, so that the multi-system networking is more flexible.
The convergence unit can realize daisy chain networking or star networking, and can also perform operations such as monitoring and parameter configuration on a remote radio frequency unit connected with the convergence unit.
When the coupling processing device sends the downlink baseband signal to the multi-system access network device, the downlink baseband signal may be sent to the baseband processing unit, or may be sent to the convergence unit, which is not limited herein.
Further, the coupling processing device may forward the downlink baseband signal of the first standard to a multi-standard remote radio frequency unit in the multi-standard access network device through the baseband processing unit or the convergence unit; and then, performing radio frequency conversion on the downlink baseband signal of the first standard through a corresponding channel in the multi-standard remote radio frequency unit, and then sending the downlink baseband signal of the first standard to the terminal equipment.
Correspondingly, the coupling processing device may also receive an uplink baseband signal sent by the baseband processing unit or the convergence unit. The aggregation unit may aggregate uplink baseband signals sent by the multiple multi-system remote radio frequency units connected thereto, and forward the aggregated uplink baseband signals to the coupling unit.
The multi-system access network equipment can also be connected with a plurality of coupling processing equipment through the baseband processing unit and the convergence unit, so that multiplexing of a plurality of first-system access network equipment is realized.
In the multi-system networking method, the coupling processing device forwards the downlink baseband signal of the first system to the multi-system remote radio frequency unit in the multi-system access network device through the baseband processing unit or the convergence unit, so that multi-system networking is more flexible.

Specifically, after receiving the downlink radio frequency signal, the coupling processing device may obtain the frequency of the downlink radio frequency signal through a carrier tracking module in the coupling processing device. For example, the transmitting frequency of the access network device of the first standard may be determined according to the frequency with the largest signal amplitude in the downlink radio frequency signal.
The coupling processing device can track the sending frequency of the first standard access network device in real time according to the frequency of the downlink radio frequency signal of the first standard when the coupling processing device is connected with the first standard access network device for the first time, so that the first standard access network device can switch in time after adjusting the working frequency, and the switching time delay is reduced.
S202, the coupling processing equipment adjusts working parameters of the coupling processing equipment according to the frequency.
Further, the coupling processing device may adjust the working parameter of the coupling processing device according to the tracked frequency, so that the working parameter is matched with the frequency of the downlink radio frequency signal. The working parameters may include an intermediate frequency point during the frequency conversion process of the downlink radio frequency signal, may also include an attenuation value, may also include an alarm threshold, and the like, and the specific type of the working parameters is not changed here.
And S203, the coupling processing equipment performs baseband conversion on the downlink radio frequency signal of the first standard based on the adjusted working parameter to obtain a downlink baseband signal of the first standard.
And the coupling processing equipment performs baseband conversion on the downlink radio frequency signal of the first standard based on the adjusted working parameter to obtain a downlink baseband signal of the first standard. Through the adjustment, the multi-system access network equipment can process the downlink baseband signal of the first system and send the downlink baseband signal to the terminal equipment.
In addition, the coupling processing device not only has a frequency tracking function, but also has a positioning function, can provide positioning service of the terminal device through the positioning module, and then reports the obtained positioning information to the multi-system access network device.
