Description

Air interface scanning system, method and communication device

This application claims priority to Chinese Patent Application No. 201410027693.3, entitled "Air Interface Scanning System, Method and Communication Equipment", filed on January 21, 2014, the entire contents of which is incorporated herein by reference. In the application.

Technical field

The present invention relates to the field of communications technologies, and in particular, to an air interface scanning system, method, and communication device.

Background technique

With the increasing use of wireless data, small base stations (ie, small base stations, also known as micro base stations) are widely used for their low cost and easy mobility. Due to the small coverage of small base stations, network coverage changes frequently in order to expand coverage or to continuously add new small base stations for expansion. When a new small base station is added, the wireless parameter planning of the newly added small base station needs to be manually completed in advance, so that the cost of the wireless parameter planning is high. In order to reduce the planning cost of the wireless parameters of the small base station, the small base station has been improved to automatically complete the automatic planning and configuration of the wireless parameters.

In order to implement automatic planning and configuration of radio parameters, it is necessary to obtain configuration information of neighboring small base stations, such as scrambling code or pilot information. Therefore, the small base station is required to receive the air interface transmission of the small cell in the neighboring cell (the small cell in the neighboring cell refers to the small base station whose coverage of the radiated signal of the service antenna overlaps with the coverage of the radiated signal of the service antenna of the small cell) Information. At present, the automatic planning and configuration of wireless parameters is implemented by adding a scanning channel to the small base station as an air interface scanning system, as shown in FIG. 1, including a scanning antenna, a signal amplifier, and a receiving signal processing channel. The information transmitted by the air interface of the neighboring cell small base station is obtained by scanning the antenna.

However, because the scanning antenna of the scanning channel is different from the service antenna of the small base station, the signal acquired by the air interface scanning channel may not be sent by the air interface of the neighboring base station of the small base station. The sent signal causes the small base station to fail to obtain the configuration information of the neighboring small base station, so that the validity of the configured wireless parameter is reduced.

The transmission direction of the electrical signal in the circulator 33 is: an electrical signal input from the first port to the circulator 33 is output from the third port; an electrical signal input from the circulator 33 by the second port is from the The first port outputs; similarly, if the electrical signal of the circulator 33 is input from the third port, it is output from the second port.

At the same time, only one channel of the first subchannel and the second subchannel is in an open state.

The transmission signal processing channel 34, the circulator 33, the first filter 31, and the service antenna constitute a service data transmission channel; the service antenna, the second filter 32, the second signal amplifier 36, and the received signal processing channel 37 The second sub-channel constitutes a service data receiving channel; the service data transmission channel and the service data receiving channel constitute a service channel of the base station; the service antenna, the first filter 31, the circulator 33, the first signal amplifier 35, and the signal processing channel 37 are received.

The working mechanism of the air interface scanning system provided by the embodiment of the present application is described below.

Please refer to FIG. 4. FIG. 4 is a schematic diagram showing the flow of signal flow when the wireless interface automatic configuration is performed in the air interface scanning system shown in FIG.

Specifically, in order to prevent the first port and the second port of the circulator from simultaneously causing signal blocking or damage to the circulator, when the wireless parameter needs to be configured, the transmission signal processing channel 34 is turned off. The air interface signal, that is, the signal that can be scanned by the service antenna, includes the downlink signal from the neighboring base station, and the frequency band is the same as the downlink signal of the base station. For convenience of distinction, it is represented by A in FIG. 4; The downlink signal whose frequency band is different from the frequency band of the downlink signal of the base station is represented by B in FIG. 4, and of course includes a signal from the mobile terminal (not shown).

The downlink intra-frequency signal (ie, the A signal) of the neighboring base station is received by the service antenna, and the A signal passes through the first filter 31, and is input to the first signal amplifier 35 via the first port and the third port of the circulator 33. The A signal amplified by a signal amplifier 35 is output to the first baseband processing unit through the first subchannel of the received signal processing channel 37.

In order to reduce unnecessary power consumption, the service data receiving channel can also be turned off when the wireless parameter configuration is performed, for example, by turning off the second signal amplifier 36 or turning off the second subchannel in the signal processing channel 37. Service data receiving channel.

After the wireless parameter configuration is completed, the normal working state can be entered to perform service data transmission. At this time, the sending signal processing channel 34 is turned on, and the scanning channel is closed, and the first signal can be turned off. The amplifier 35, or the first sub-channel in the receiving signal processing channel 37 is turned off; if the service data receiving channel is also closed when the parameter configuration is performed, the service data receiving channel needs to be turned on when the wireless parameter configuration is completed.

When the wireless parameter configuration is completed and the base station enters the normal working state (that is, when the service data is normally processed), the flow direction diagram of the signal flow when the air interface scanning system shown in FIG. 3 transmits the service data is as shown in FIG. 5;

The air interface signal, that is, the signal that the service antenna can scan, includes the signal from the neighboring base station, and specifically has the same downlink signal from the neighboring base station and the frequency band of the downlink signal of the base station, for convenience of distinguishing, used in FIG. A indicates; there is also a downlink signal from the neighboring base station, the frequency band is different from the frequency band of the downlink signal of the base station, and is represented by B in FIG. 5; the air interface signal further includes a signal from the terminal, which is represented by D in FIG. 5; The transmission signal including the base station is denoted by C in FIG.

As shown in FIG. 5, after the downlink intra-frequency signal (ie, the A signal) of the neighboring base station is received by the service antenna, since the scanning channel is closed, the receiving signal processing channel 37 is not entered; and the downlink base station is not in the same frequency. After the signal (ie, the B signal) is received by the service antenna, since both the first filter 31 and the second filter 32 allow only the signals of the preset frequency band to pass, the B signal does not enter the received signal processing channel 37; After the signal of the terminal (ie, the D signal) is received by the service antenna, it is filtered by the second filter 32 and then enters the second signal amplifier 36. The amplified D signal enters the second subchannel of the received signal processing channel 37, and then enters the The third baseband processing unit completes the reception of the service data; and when the service data needs to be transmitted, the second baseband processing unit performs baseband processing on the service data to generate a to-be-transmitted signal (ie, C signal), and the C signal enters the transmission signal processing channel 34. After being output from the transmission signal processing channel 34, it is counted in the circulator 33, and then outputted from the first port of the circulator to the first filter 31, and the filtered C signal passes through the service. Line sent out.

When the air interface scanning system provided by the embodiment of the present application obtains the configuration information of the neighboring base station by using the air interface scanning system provided by the embodiment of the present application, the service antenna acquires the adjacent frequency band of the same frequency band as the transmitting signal of the base station. The signal sent by the base station is filtered by the first filter and sent to the first signal amplifier for amplification by the circulator, and the amplified signal is sent to the first baseband processing unit through the first sub-channel of the received signal processing channel for wireless parameter configuration. It can be seen that this application passes the industry.
