Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. 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.
It should be noted that, the integrated pico-base station includes a home-level pico-base station and an enterprise-level pico-base station, the interception circuit is mainly applied to a location access restriction function and a base station SON function based on information such as a macro-network ECGI, and the interception circuit includes two interception loops to acquire the macro-network ECGI of different frequency bands; the two interception circuits and the radio frequency transceiving links of the integrated pico-base station share the same radio frequency transceiver and share the antenna of the integrated pico-base station, the interception circuit of the pico-base station and the normal radio frequency transceiving links of the pico-base station are switched through the radio frequency switch, and the frequency band of the interception circuit is the downlink frequency band of the macro-station of the cell. Wherein SON refers to self-organizing networks.
Referring to fig. 1, a module structure of an interception circuit applied to an integrated pico-base station according to an embodiment of the present application is shown, for convenience of description, only the relevant portions of the embodiment are shown, and the following details are described below:
the above listening circuit applied to the integrated pico-base station includes a transceiver module 102, a processing module 104, and at least two sub-listening modules 101, where each sub-listening module 101 is configured to receive and listen to radio frequency signals of different preset frequency bands, and each sub-listening module 101 includes an antenna assembly 1011, a radio frequency switch assembly 1012, a first filtering assembly 1013, a low noise amplification assembly 1014, and a second filtering assembly 1015.
An antenna assembly 1011 is in communication with the pico base station.
The rf switch module 1012 is connected to the antenna module 1011, and is configured to switch on or off according to a real-time frequency band of the rf signal received by the antenna module 1011 and after comparing the real-time frequency band with a preset frequency band.
The first filtering component 1013 is connected to the rf switch component 1012, and is configured to perform a filtering process on the transmitted rf signal.
The low-noise amplification module 1014 is connected to the first filtering module 1013, and is configured to perform noise filtering and amplification processing on the radio-frequency signal after the primary filtering processing.
The second filtering component 1015 is connected to the low-noise amplifying component 1014, and is configured to perform secondary filtering processing on the radio frequency signal after the noise filtering and amplifying processing.
The transceiver component 102 is connected to each second filtering component 1015, and is configured to receive the radio frequency signal after the second filtering process, so as to perform analog-to-digital conversion on the radio frequency signal and send the radio frequency signal to the processing component 104.
The processing component 104 is connected to the transceiver component 102, and is configured to analyze the radio frequency signal sent by the transceiver component 102, obtain ECGI information, and detect the ECGI information. The ECGI specifically refers to an evolved universal mobile telecommunications system terrestrial radio access network cell global identifier.
Specifically, the frequency bands of 4G networks of operators such as china telecom, china unicom and the like in China at present include Band1 and Band3 frequency bands, and the working frequency Band of a macro cell accessed to the pico-base station may be Band1 or Band 3.
Therefore, as an optional implementation manner, the above sensing circuit specifically includes two sub-sensing modules 101, where the two sub-sensing modules 101 are respectively configured to receive and sense radio frequency signals in the Band1 frequency Band and the Band3 frequency Band, so as to sense different frequency bands of the macro station to obtain ECGI information. The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention.
Of course, at least two sub-listening modules 101 are also configured to receive and listen to radio frequency signals in Band38 frequency Band, Band39 frequency Band, and Band40 frequency Band.
Specifically, when the real-time frequency band of the radio frequency signal received by the antenna component 101 is consistent with the preset frequency band, the corresponding radio frequency switch component 1012 is turned on, so that the located listening loop works; when the real-time frequency band of the radio frequency signal received by the antenna component 101 is not consistent with the preset frequency band, the corresponding radio frequency switch component 1012 is turned off, so that the monitoring loop in which the radio frequency switch component is located stops working. I.e. one and only one of the at least two sub-listening modules 101 is in operation.
As an optional implementation manner, the antenna assembly 1011 is implemented by using a conventional radio frequency antenna ANT, so that the interception circuit directly uses two antennas of the pico-base station without additionally adding a dedicated antenna, thereby greatly reducing the design difficulty of the pico-base station, and the interception circuit only works when the pico-base station is opened, and is in a standby state after the pico-base station is successfully opened, thereby reducing power consumption.
As an alternative embodiment, the rf switch component 1012 is implemented by using an rf switch, and the macro-station listening circuit of the pico-base station shares an antenna port with a transceiver link of the pico-base station through the rf switch.
Specifically, the rf switch is also called a microwave switch, which realizes the function of controlling the switching of microwave signal channels.
As an alternative implementation, the first filtering component 1013 and the second filtering component 1015 are implemented by using filters.
Specifically, the filter is a filter circuit composed of a capacitor, an inductor, and a resistor. The filter can effectively filter the frequency point of the specific frequency in the power line or the frequencies except the frequency point to obtain a power signal of the specific frequency or eliminate the power signal of the specific frequency. A filter is a frequency-selective device that passes certain frequency components of a signal while significantly attenuating other frequency components. By using the frequency selection function of the filter, interference noise can be filtered out or spectrum analysis can be carried out. Therefore, the first filtering component 1013 and the second filtering component 1015 are used to filter out the rf signal with a specific frequency, so as to prevent interference and achieve a more precise listening effect.
As an alternative embodiment, the low noise amplifying component 1014 is implemented by a low noise amplifier with a switch function.
Specifically, the low noise amplifiers have a closing function, and when the ECGI information is obtained by interception, the low noise amplifier of the interception circuit is in a working state, and is in a closing state after the interception start task is completed; the low noise amplifier has 20dB of isolation in a closed state, and can basically not receive downlink signals transmitted by the macro base station in a working state by the pico base station together with the radio frequency switch, so that the receiving sensitivity of the system can be ensured not to be influenced by an intercepted link.
As an alternative embodiment, the transceiver module 102 is implemented by a signal transceiver chip with model number AD9363 BBCZ.
Specifically, the integrated pico-base station uses a dual-transceiver and dual-transmission radio frequency transceiver AD9363, and two RX links of the device support three-channel reception, so that a receiver of the listening circuit can utilize the existing radio frequency transceiver of the pico-base station, and the design cost can be reduced without additionally increasing the receiver.
As an alternative embodiment, the processing component 104 is implemented by a baseband chip SOC.
Referring to fig. 2, a module structure of an interception device applied to an integrated pico-base station according to an embodiment of the present application is shown, for convenience of description, only the relevant portions of the embodiment are shown, and the following details are described:
the application also provides an interception device applied to the integrated pico base station, which comprises:
the monitoring circuit as described above; and
and the signal processing circuit is connected with the monitoring circuit and used for outputting a downlink signal to be fed back to the pico base station after the uplink signal output by the pico base station is subjected to signal processing.
In addition, the monitoring device is additionally provided with a signal processing circuit in addition to the monitoring circuit, so that after the uplink signal output by the pico-base station is processed, the downlink signal is output to be fed back to the pico-base station. Therefore, the functional description and the principle description of the transceiving component 102, the processing component and the at least two sub-sensing modules 101 in the sensing circuit can refer to the embodiment of fig. 1, and will not be described in detail herein.
As an optional implementation, the signal processing circuit includes at least two sub-signal processing modules 103, the at least two sub-signal processing modules 103 are respectively connected to the at least two sub-listening modules 101 in a one-to-one correspondence, and each sub-signal processing module 103 includes a balun 1031, a pre-stage amplifier 1032, a final-stage power amplifier 1033, an isolator 1034, a duplexer 1035, a low noise amplifier 1036, and a filter 1037.
The preamplifier 1032 is connected to the balun 1031, and is configured to amplify the uplink signal received by the transceiver module 102.
The final power amplifier 1033 is connected to the pre-amplifier 1032 and configured to perform power amplification on the amplified uplink signal.
The isolator 1034 is connected to the final power amplifier 1033, and is configured to perform signal isolation on the power-amplified uplink signal.
The duplexer 1035 is connected to the isolator 1034 and the rf switch component 1012, and is configured to perform format conversion on the uplink signal after signal isolation, and output a downlink signal.
The low noise amplifier 1036 is connected to the duplexer 1035, and is configured to perform noise filtering and amplification processing on the downlink signal.
The filter 1037 is connected to the low noise amplifier 1036 and the transceiver module 102, and is configured to filter the downlink signal after the noise filtering and amplifying process, so as to feed back the downlink signal to the pico-base station.
As an alternative embodiment, the duplexer 1035 is further configured to receive the rf signal transmitted by the antenna element 1011 when the rf switch element 1012 connected to the duplexer is turned off.
Fig. 3 and4 respectively show an electrical structure of a first sub-sensing circuit and a first sub-signal processing circuit in the sensing device applied to the integrated pico-base station, and an electrical structure of a second sub-sensing circuit and a second sub-signal processing circuit, and the following describes an operation principle of the sensing circuit and the sensing device applied to the integrated pico-base station with reference to fig. 1 to 4:
after the pico-base station operates, the SON function system is turned on, and is switched to the sub-interception module 101 as the radio frequency switch in fig. 3 and fig. 4, and receives signals of downlink of macro-cell Band1 or Band3, because the RX link in the transceiver module 102 used in the pico-base station uses the same local oscillator signal, the interception device detects whether the first interception loop can receive a Band1 downlink radio frequency signal, and if the RX link can detect a Band1 frequency Band signal, the interception device analyzes ECGI information in the signal, and if the Band1 radio frequency signal is not detected, the interception device is switched to the second interception loop to detect a Band3 downlink radio frequency signal.
When the base station switches to a listening loop, the listening device will enable the low noise amplifier LNA switch of the corresponding listening loop. When the base station is in a working state and a non-listening state, the enabling switch of the low noise amplifier LNA is closed, so that the RX receiving sensitivity is not influenced in the working state. In this embodiment, the base station operates in the Band1 frequency Band. If the circuit diagram of the listening loop of the base station operating in the Band3 frequency Band can completely correspond to the base station of the Band1, the RX and TX circuits of the base station operating normally are replaced by the duplexer 1035, the isolator 1034, the preamplifier 1032, the final power amplifier 1033 and the low noise amplifier 1036 of the Band 3.
Therefore, the integrated pico-base station supports self-starting, monitors peripheral macro-stations, analyzes broadcasting, automatically adds neighbor cells, self-configures PCI, acquires ECGI information of a macro-base station in the same cell through a monitoring loop to realize a position access limiting function, and can normally open the station when the pico-base station acquires the correct ECGI information of the macro-base station in the same cell, otherwise, the pico-base station cannot open the station under the same cell.
To sum up, above-mentioned interception circuit and device applied to integration leather base station in this application embodiment, including receiving and dispatching subassembly, processing module and two at least sub-interception modules, every sub-interception module is used for receiving and intercepts the radio frequency signal of different preset frequency channels, every sub-interception module all includes the antenna module, the radio frequency switch subassembly, first filtering component, low noise amplification subassembly and second filtering component, through carrying out communication connection with the leather base station, and according to the real-time frequency of the radio frequency signal who receives, turn on the interception return circuit that corresponds after comparing with preset frequency channel, carry out primary filtering, noise filtering and amplification processing to the radio frequency signal in order afterwards, and output to receiving and dispatching subassembly after the secondary filtering carries out analog-to-digital conversion, send for processing module in order to obtain ECGI information and detect after radio frequency signal analyzes. Therefore, the effect of monitoring the radio frequency signal is realized, and the requirement that the pico base station has an SON function and acquires information such as ECGI of the macro network is met; meanwhile, the special antenna without an interception circuit is realized by utilizing the radio frequency switch component, the design difficulty of the pico-base station is reduced, the adopted receiving and transmitting components support multi-channel receiving, a receiver does not need to be additionally arranged, the design cost is reduced, and the problems that the position access of the existing integrated pico-base station based on information such as a 4G macro-network ECGI is limited and the existing integrated pico-base station does not have an SON function are solved.
