Description

Technical Field

[0001] The embodiments of the present disclosure relate to the field of base station antennas, and in particular to a base station antenna channel topology detection method, electronic equipment, and program product. Background Art

[0002] In existing network deployments, the reliability of connections between base station antenna ports and remote radio units (RRUs) faces significant challenges. Manually connected base station antenna path topology implementations often suffer from physical connection errors. Furthermore, the AISG (Antenna Interface Standard Group) protocol in related technologies fails to define the physical location of ports, coaxial cables lack directionality, and there is a lack of digital verification mechanisms between RRUs and antennas. Consequently, these technologies cannot accurately determine base station antenna path topology. Relying solely on manual on-site inspections incurs extremely high maintenance costs and is prone to errors. This leads to a significant number of misconnected sites in existing networks, significantly impacting signal coverage and communication quality, and even causing service interruptions. Therefore, implementing real-time connection verification of base station antenna path topology at the physical layer and achieving highly accurate, non-intrusive, and automated detection of base station antenna path topology remains a pressing challenge.

As used in this disclosure, the singular forms "a" and "the" are also intended to include plural forms, unless the context clearly indicates otherwise.

It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and this disclosure, and will not be interpreted as having an idealized or overly formal meaning unless expressly defined in this disclosure.

[0058] With the evolution of communications technology, modern base station antenna systems are showing the following development trends: Antenna port density within a single antenna has significantly increased, with multi-frequency, multi-standard antenna units integrated and converged. According to statistics, multi-band composite antennas currently account for over 70% of the total. Furthermore, the deployment density of Remote Radio Units (RRUs) has tripled compared to the 4G (fourth-generation communication technology) era, with the number of RRUs per base station reaching 12-24. Antenna equipment now supports multi-dimensional coverage modes, such as three-sector and six-sector coverage. In existing network deployments, the reliability of the connection between antenna ports and RRUs faces significant challenges, with manual wiring often subject to numerous physical connection errors:

[0059] - Cross-band misconnection; for example, a 900MHz port is mistakenly connected to a 1.8GHz RRU;

[0060] - Sector misalignment; for example, the port of sector A is mistakenly connected to the port of sector B;

[0061] - Polarization direction confusion; for example, ±45° dual-polarization antennas are crossed and connected incorrectly;

[0062] - The order of MIMO (Multiple-input Multiple-output) channels is reversed; for example, channels 1-8 in an 8T8R system are connected out of order.

[0063] The AISG (Antenna Interface Standard Group) protocol in related technologies fails to define the physical location of ports, coaxial cables lack directional sensing, and there is a lack of digital verification mechanisms between the RRU and the antenna. Consequently, these technologies cannot accurately determine base station antenna path topology. Relying solely on manual on-site inspections incurs extremely high maintenance costs and is prone to errors. This leads to a large number of misconnected cable sites in existing networks, significantly impacting signal coverage and communication quality, and even causing service interruptions. Therefore, achieving real-time connection verification of base station antenna path topology at the physical layer and achieving highly accurate, non-intrusive, and automated detection of base station antenna path topology remains a pressing challenge.

[0064] The embodiment of the present disclosure sequentially sends inquiry signals to the antenna channels corresponding to each radio frequency channel in the remote radio frequency unit (RRU) based on the channel topology detection instruction; sends the antenna channel identity ID information returned by the antenna channel based on the inquiry information to the network; and sends the antenna channel identity ID information and the radio frequency channel ID information corresponding to the radio frequency channel that sent the inquiry signal to the baseband processing unit (BBU), so that the BBU constructs a mapping relationship between the antenna channel ID information and the radio frequency channel ID information corresponding to the radio frequency channel that sent the inquiry signal as the base station antenna channel topology. Through this embodiment, real-time connection verification of the base station antenna channel topology can be achieved from the physical layer, realizing high-precision, non-intrusive automatic detection of the base station antenna channel topology.

[0065] The embodiments of the present disclosure can be applied to any product related to base station antennas, and can be applied to but not limited to 4G, 5G and other base station antennas.

[0066] The following is a detailed introduction to the embodiments of the present disclosure.

[0067] The embodiment of the present disclosure provides a method for detecting base station antenna channel topology. The solution can be applied to the RRU (Remote Radio Unit) side, such as Figure 1 As shown, it includes steps S11-S13:

[0068] S11 . Based on the channel topology detection instruction, query signals are sent to the antenna channels corresponding to the radio frequency channels in the RRU in sequence.

[0069] In the embodiment of the present disclosure, the base station antenna channel topology refers to the mapping relationship between the antenna channel ID (Identity Document) information (or antenna channel code) of the antenna channel in the base station antenna 100 and the radio frequency channel ID (or radio frequency channel number) of the radio frequency channel in the RRU 200.

[0070] In the embodiment of the present disclosure, the antenna channel ID information may include but is not limited to at least one of the following: antenna device number, frequency band information, and channel number.

[0071] In the embodiment of the present disclosure, a mapping relationship between the antenna channel and the radio frequency channel may be determined by sending a signal between the antenna channel and the radio frequency channel.

[0072] In the embodiment of the present disclosure, Figure 2 As shown, sending inquiry signals to the antenna channels corresponding to the radio frequency channels in the remote radio unit RRU in sequence based on the channel topology detection instruction may include steps S21-S22:

[0073] S21. Based on the channel topology detection instruction, perform a multiple-select-one operation on multiple radio frequency channels in sequence, and select one radio frequency channel from the multiple radio frequency channels each time as a target radio frequency channel.

[0074] In the embodiment of the present disclosure, the solution of the embodiment of the present disclosure can be implemented by a detection system of the base station antenna channel topology, such as Figure 3 As shown, the base station antenna channel topology detection system 10 can be integrated into the base station antenna 100, RRU 200, and BBU (Building Baseband Unit) 300. It can include, but is not limited to, a topology mapping unit 101 located in the base station antenna 100, an information reading and processing unit 201 located in the RRU 200, and a mapping relationship construction unit 301 located in the BBU 300. There can be multiple topology mapping units 101, and their number is equal to the number of RF channels for topology identification.

[0075] In the embodiment of the present disclosure, the information reading and processing unit 201 is mainly responsible for transmitting the inquiry signal and receiving the tag signal returned by the topology mapping unit 101 based on the inquiry signal, and performing subsequent processing based on the tag signal.

[0076] In the embodiment of the present disclosure, the topology mapping unit 101 is mainly responsible for receiving the inquiry signal and triggering the transmission of the tag signal based on the inquiry signal.

[0077] In the embodiment of the present disclosure, Figure 4As shown, the base station antenna 100 may also include M antenna channels 102, each of which is connected to M topology mapping units 101 (M is a positive integer). Each antenna channel 102 in the base station antenna 100 is connected in series with one topology mapping unit 101 at the main output port, for a total of M topology mapping units. Each topology mapping unit 101 may include an antenna RF input port 1011, an antenna RF output port 1012, a signal coupling module 1013, and a tag module 1014. The tag module 1014 in the i-th topology mapping unit 101 carries the antenna channel ID information of the i-th antenna channel.

[0078] In the embodiment of the present disclosure, two PCB (Printed Circuit Board) process embodiments of the topology mapping unit 101 are given below.

[0079] In the embodiment of the present disclosure, Figure 5 As shown, the PCB of the topology mapping unit 101 includes an antenna RF input port 1011 and an antenna RF output port 1012. Antenna RF input port 1011 is connected to the RF channel of the RRU, while antenna RF output port 1012 is connected to the antenna channel of the base station antenna. The interrogation signal transmitted from the RF channel passes through the signal coupling region 1013A of the signal coupling module 1013, which couples the interrogation signal to the tag chip 1014A. The signal coupling module 1013 can be a PCB microstrip coupler. The PCB also includes a load resistor 1013B for the isolation port of the PCB microstrip coupler. A microstrip branch load 1014B is also provided on the PCB to adjust the impedance of the signal coupling module 1013 to achieve equal conjugate matching with the tag chip impedance to achieve better coupling of the RF signal. The tag chip 1014A can be a passive RFID (Radio Frequency Identification) chip, which is energized by the interrogation signal to generate a reflected modulated signal (i.e., the tag signal).

[0080] In the embodiment of the present disclosure, Figure 6As shown, the PCB of topology mapping unit 101 includes an antenna RF input port 1011 and an antenna RF output port 1012. Antenna RF input port 1011 is connected to the RF channel of the RRU, and antenna RF output port 1012 is connected to the antenna channel of the base station antenna. The interrogation signal transmitted by the RF channel is coupled to tag chip 1014A via signal coupling module 1013. Equivalent inductor coil 1014D is interconnected with tag chip 1014A. The metal ground below equivalent inductor coil 1014D is hollowed out 1014C to achieve better coupling of RF signals. Tag chip 1014A can be a passive RFID chip, which is activated by the interrogation signal to generate a reflected modulated signal.

[0081] In the embodiment of the present disclosure, Figure 7 As shown, the RRU 200 may further include M RF channels 202 (e.g., RF channel 1, RF channel 2, ..., RF channel M), M channel couplers 203 (e.g., channel coupler 1, channel coupler 2, ..., channel coupler M) corresponding to the M RF channels 202, and M RF transceiver ports 204 (e.g., RF transceiver port 1, RF transceiver port 2, ..., RF transceiver port M). The information reading and processing unit 201 may include a tag reader 2011 and an M-to-1 switch 2012.

[0082] In the embodiment of the present disclosure, each channel coupler 203 is respectively connected to an RF channel selected by the M-to-1 switch 2012, and each channel coupler 203 corresponds to an RF transceiver port 204, each RF transceiver port 204 corresponds to a topology mapping unit 101, and corresponds to the antenna RF input port 1011, antenna RF output port 1012, signal coupling module 1013 and label module 1014 included in the topology mapping unit 101, wherein each RF transceiver port 204 is connected to the antenna RF input port 1011 in the corresponding topology mapping unit 101.

[0083] In the embodiment of the present disclosure, multiple RF channels can be selected to one by one, and one of the M channel couplers 203 can be sequentially selected to be turned on through the M-to-1 switch 2012, and the RF channel connected to the turned-on channel coupler 203 is used as the target RF channel.

[0084] In the embodiment of the present disclosure, when the base station antenna channel topology detection system is working, the network manager can initiate a channel topology detection instruction, and the processing unit of the information reading and processing unit 201 in the RRU 200 controls the M-to-1 switch 2012 to perform M-to-1 to turn on one radio frequency channel, and determines the topology mapping unit 101 that needs to be queried. For example, the control unit of the information reading and processing unit 201 controls the M-to-1 switch 2012 therein to turn on the i-th channel, thereby selecting the i-th radio frequency channel.

[0085] In the disclosed embodiment, the M-to-1 switch 2012 has M switch paths, each of which is connected to one of the M RF channels 202. The M-to-1 switch 2012 can only conduct one switch path at a time, that is, the M-to-1 switch 2012 can only conduct one of the M paths at a time, and all other paths except the conducting path are in the off state.

[0086] In the embodiment of the present disclosure, each time a switch path is turned on, the channel coupler 203 corresponding to the switch path is turned on, that is, the RF channel coupled to the channel coupler 203 is selected as the target RF channel. By successively controlling the M-to-1 switch 2012 to turn on different switch paths, each of the M RF channels can be selected once, so that each RF channel is used as a target RF channel. The tag reader 2011 transmits an inquiry signal once to detect the antenna channel corresponding to each RF channel.

[0087] In the embodiment of the present disclosure, based on the above solution, the information reading and processing unit 201 can select each radio frequency channel in turn through the M-to-1 switch 2012 and couple the generated query signal to the corresponding antenna channel.

[0088] S22: Generate an inquiry signal based on the channel topology detection instruction, and send the inquiry signal to the target antenna channel connected to the target radio frequency channel in the base station antenna through the target radio frequency channel selected each time.

[0089] In the disclosed embodiment, when the base station antenna channel topology detection system is operating, the network administrator can initiate a channel topology detection instruction. The processing unit of the information reading and processing unit 201 within the RRU 200 can control the tag reader 2011 to generate an inquiry signal. The generated inquiry signal is then transmitted to the external base station antenna via the target radio frequency channel selected for conduction by the M-to-1 switch 2012. The inquiry signal sent to each target radio frequency channel can be the same or different.

[0090] In the embodiment of the present disclosure, sending the inquiry signal to the target antenna channel connected to the target radio frequency channel in the base station antenna through the target radio frequency channel selected each time may include:

[0091] Transmitting the interrogation signal to a target channel coupler corresponding to the target radio frequency channel through the target radio frequency channel;

[0092] coupling the inquiry signal to the target RF transceiver port corresponding to the target channel coupler through the target channel coupler;

[0093] The query signal is coupled to the target antenna RF input port corresponding to the target channel coupler through the target RF transceiver port, so that the query signal is transmitted from the target antenna RF input port to the target signal coupling module corresponding to the target antenna RF input port, and the target signal coupling module couples the query signal to the corresponding target tag module, wherein the target signal coupling module is connected to the corresponding target antenna channel through the target antenna RF output port.

[0094] In the disclosed embodiment, each RF transceiver port 204 of each RF channel 202 within the RRU is equipped with a channel coupler 203, for a total of M channel couplers 203. Each path of the M-to-1 switch 2012 is interconnected with a channel coupler 203. The function of the channel coupler 203 is to couple the query signal transmitted from the M-to-1 switch 2012 to the RF transceiver port 204 of the RRU.

[0095] In the embodiment of the present disclosure, assuming that the i-th path of the M-to-1 switch 2012 and the i-th channel coupler 203 are interconnected one by one, the inquiry signal can be coupled to the i-th RF transceiver port 204 through the i-th channel coupler 203, and then transmitted to the antenna to the corresponding i-th antenna channel through the RF cable.

[0096] S12. Receive the antenna channel identity ID information returned by the antenna channel based on the inquiry information, and send the antenna channel identity ID information and the radio frequency channel ID information corresponding to the radio frequency channel that sends the inquiry signal to the baseband processing unit BBU, so that the BBU establishes a mapping relationship between the antenna channel ID information and the radio frequency channel ID information corresponding to the radio frequency channel that sends the inquiry signal as the determined base station antenna channel topology.

[0097] In the embodiment of the present disclosure, each signal coupling module 1013 in the base station antenna 100 is responsible for coupling the inquiry signal sent by the RRU RF channel to the tag module 1014 in the base station antenna 100. After receiving the inquiry signal, the tag module 1014 is activated and reflects the tag signal stored in the tag module 1014 to the information reading and processing unit 201 in the RRU 200 by modulating the RF carrier.

[0098] In the embodiment of the present disclosure, it is assumed that the inquiry signal transmitted by the i-th antenna channel can couple a portion of the signal to the tag module 1014 via the corresponding i-th signal coupling module 1013. After receiving the inquiry signal, the tag in the tag module 1014 is activated and transmits the tag signal carrying the antenna channel ID information. The tag signal is coupled to the i-th antenna channel through the i-th signal coupling module, and further transmitted back to the i-th RF transceiver port 204 of the RRU through the RF cable between the base station antenna 100 and the RRU 200. Then, it is coupled to the i-th path of the M-to-1 switch through the i-th channel coupler 203, and further returned to the tag reader 2011 in the RRU 200, and is received and parsed by the tag reader 2011 to obtain the antenna channel ID information.

[0099] In the embodiment of the present disclosure, receiving antenna channel identity ID information returned by the antenna channel based on the query information may include:

[0100] The receiving antenna channel returns the tag signal based on the query information sent each time; the tag signal contains the antenna channel ID information;

[0101] Parse the tag signal to obtain the antenna channel ID information returned by the antenna channel each time.

[0102] In the embodiment of the present disclosure, it can be seen from the above scheme that the processing unit of the information reading and processing unit 201 can control the M-to-1 switch 2012 to perform multiple M-to-1 actions, thereby selecting M radio frequency channels once respectively, so that each radio frequency channel is turned on once as a target radio frequency channel respectively, and the control unit of the information reading and processing unit 201 can control the tag reader 2011 to generate an inquiry signal. Each time a target radio frequency channel is selected, the inquiry signal is sent to the target antenna channel connected to the target radio frequency channel through the target radio frequency channel. Therefore, each time the target tag module connected to the target antenna channel is activated by the inquiry signal, a tag signal is generated and returned to the tag reader 2011 through the target antenna channel and the target radio frequency channel. The tag reader 2011 receives and parses the tag signal returned each time and obtains the antenna channel ID information returned each time.

[0103] In the embodiment of the present disclosure, when the tag reader 2011 generates an inquiry signal, it can generate a corresponding inquiry signal for each target RF channel that is turned on, and send the corresponding inquiry signal through the target RF channel. Alternatively, it can generate an inquiry signal only once, and when different target RF channels are turned on, the same inquiry signal can be sent through the different target RF channels.

[0104] The embodiment of the present disclosure provides a base station antenna channel topology detection method, which is applied to the base station antenna side. The base station antenna includes multiple antenna channels, such as Figure 8 As shown, the method includes steps S31-S33:

[0105] S31 . Acquire an inquiry signal sent by a target radio frequency channel through a target antenna channel connected to a target radio frequency channel selected in an RRU.

[0106] In the embodiment of the present disclosure, obtaining the inquiry signal sent by the target radio frequency channel selected in the remote radio frequency unit RRU through the target antenna channel connected to the target radio frequency channel may include:

[0107] Receiving, through the target antenna RF input port corresponding to the target antenna channel, an inquiry signal transmitted by the target RF transceiver port corresponding to the target antenna channel; the inquiry signal is obtained by the target channel coupler corresponding to the target RF transceiver port from the target RF channel selected based on the M-to-1 switch;

[0108] The target antenna RF input port sends the inquiry signal to the target signal coupling module corresponding to the target antenna channel.

[0109] In the embodiment of the present disclosure, for example, after the inquiry signal is coupled to the i-th RF transceiver port 204 via the i-th channel coupler 203, it can first be transmitted to the corresponding i-th antenna channel via the RF cable between the base station antenna 100 and the RRU 200. The i-th antenna channel transmits the inquiry signal to the i-th signal coupling module 1013.

[0110] S32: coupling the inquiry signal to the target tag corresponding to the target antenna channel to activate the target tag.

[0111] In the embodiment of the present disclosure, coupling the interrogation signal to the target tag corresponding to the target antenna channel to activate the target tag may include:

[0112] The target signal coupling module couples the inquiry signal to the target tag module corresponding to the target antenna channel to activate the target tag module.

[0113] In the embodiment of the present disclosure, each signal coupling module 1013 in the base station antenna 100 is responsible for coupling a portion of the inquiry signal sent by the RRU RF channel to the corresponding tag module 1014 in the base station antenna 100. After the tag module 1014 obtains the inquiry signal, it is activated, and the signal coupling module 1013 will send the other portion of the inquiry signal to the connected target antenna channel through the antenna RF output port 1012.

[0114] In the embodiment of the present disclosure, for example, in the i-th antenna channel, the inquiry signal couples a portion of the signal to the tag module 1014 via the i-th signal coupling module 1013 , and the tag in the tag module 1014 is activated after receiving the inquiry signal.

[0115] In the embodiment of the present disclosure, when sending the inquiry signal, it is necessary to set appropriate inquiry signal strength and signal coupling strength to ensure that the tag module 1014 can be activated; at the same time, it is necessary to ensure the isolation between the signal coupling module 1013 and the remaining tag modules 1014 (i.e., non-target tag modules) to avoid activating other tag modules 1014, thereby causing reflection responses of multiple tag modules 1014, and avoiding signal interference causing ID recognition confusion.

[0116] In the embodiment of the present disclosure, the tag module 1014 may be a passive tag, which does not require a battery and is activated to generate a reflection signal (ie, a tag signal) by being powered by an inquiry signal.

[0117] S33: The target tag returns the antenna channel identity ID information of the target antenna channel to the RRU via the target radio frequency channel.

[0118] In the embodiment of the present disclosure, the target tag returns the antenna channel identity ID information of the target antenna channel to the RRU via the target radio frequency channel, which may include:

[0119] The target tag reflects the tag information carrying the antenna channel ID information of the target antenna channel to the RRU through the target radio frequency channel in the form of modulated radio frequency carrier.

[0120] In an embodiment of the present disclosure, the target tag module can couple the tag signal containing the antenna channel ID information to the corresponding target antenna RF input port through the target signal coupling module corresponding to the target tag module; the target antenna RF input port transmits the tag signal to the target RF transceiver port corresponding to the target antenna channel through the cable between the base station antenna and the RRU, so as to send the tag signal through the target RF transceiver port through the corresponding target channel coupler and the corresponding target switch path in the M-to-1 switch to the tag reader.

[0121] In the embodiment of the present disclosure, the activated tag module 1014 can add the antenna channel ID information stored in the tag module 1014 to the tag signal, and reflect it to the information reading and processing unit 201 in the RRU 200 by modulating the radio frequency carrier.

[0122] In the embodiment of the present disclosure, for example, the tag signal is coupled to the i-th antenna RF input port through the i-th signal coupling module 1013, and further transmitted back to the i-th RF transceiver port of the RRU through the RF cable between the antenna and the RRU, and then coupled to the i-th path of the M-to-1 switch through the i-th channel coupler 203 connected to the i-th RF transceiver port, and further returned to the tag reader 2011 in the RRU 200, and is received and parsed by the tag reader to obtain the antenna channel ID information corresponding to the i-th antenna channel.

[0123] In the embodiment of the present disclosure, if the antenna channel 102 and the RF channel 202 are correctly connected, the antenna channel ID information contained in the tag signal parsed by the tag reader 2011 should be the ID information of the i-th antenna channel. Conversely, if the antenna channel 102 and the RF channel 202 are incorrectly connected, the antenna channel ID information contained in the tag signal parsed by the tag reader 2011 should not be the ID information of the i-th antenna channel.

[0124] In the embodiment of the present disclosure, based on the above solution, each channel of the M-to-1 switch 2012 is turned on in sequence, and the above process is repeated to complete the parsing of M antenna channel ID information.

[0125] In an embodiment of the present disclosure, the tag reader 2011 may send the parsed antenna channel ID information and the RF channel ID information corresponding to the RF channel for sending the inquiry signal to the BBU, so as to determine the actual base station antenna channel topology through the BBU.

[0126] The embodiment of the present disclosure also provides a base station antenna channel topology detection method, which is applied to a baseband processing unit BBU, such as Figure 9 As shown, the method includes steps S41-S42:

[0127] S41. Obtain the antenna channel identity ID information sent by the RRU and the radio frequency channel ID information corresponding to the radio frequency channel that sends the inquiry signal; the antenna channel ID information is the return signal of the antenna channel based on the inquiry information received after the RRU sends an inquiry signal to the antenna channel corresponding to each radio frequency channel in the RRU in turn based on the channel topology detection instruction.

[0128] In the embodiment of the present disclosure, the BBU may receive the antenna channel ID information sent by the tag reader 2011 of the RRU and the radio frequency channel ID information corresponding to the radio frequency channel through which the inquiry signal is sent.

[0129] S42: Construct a mapping relationship between the antenna channel ID information and the radio frequency channel ID information corresponding to the radio frequency channel for sending the inquiry signal as the base station antenna channel topology.

[0130] In the embodiment of the present disclosure, the solution of this embodiment may be applied to the mapping relationship construction unit 301 in the BBU 300 , and the mapping relationship construction unit 301 may be implemented by a processor of the BBU 300 .

[0131] In the embodiment of the present disclosure, determining the mapping relationship between the antenna channel ID information and the radio frequency channel ID information corresponding to the radio frequency channel for sending the inquiry signal may include:

[0132] The antenna channel ID information returned by the antenna channel each time is stored in correspondence with the radio frequency channel ID information of the radio frequency channel that sends the inquiry signal at that time;

[0133] The corresponding relationship between all stored antenna channel ID information and radio frequency channel ID information is used as a mapping relationship.

[0134] In an embodiment of the present disclosure, the BBU 300 may set a corresponding list or data matrix to store the antenna channel ID information received each time in correspondence with the RF channel ID information of the corresponding connected RF channel, thereby obtaining a mapping relationship between the antenna channel ID information of all antenna channels and the RF channel ID information of the corresponding connected RF channels.

[0135] In the embodiment of the present disclosure, the BBU 300 may send the mapping relationship to the network management 400 so that the network management 400 presents the mapping relationship, thereby establishing a mapping relationship between the antenna channel ID information and the radio frequency channel ID information.

[0136] In an embodiment of the present disclosure, the method may further include:

[0137] A correspondence between the device information of the electrical tilt module bound to the antenna channel ID information and the RF channel ID information is established; the electrical tilt module is used to adjust the antenna beam parameters of the bound antenna channel.

[0138] In the embodiment of the present disclosure, by matching the device information (such as the device number) of the electric tilt module bound to the antenna channel ID information with the cell ID (or RF channel ID information), subsequent intelligent network optimization is facilitated.

[0139] In an embodiment of the present disclosure, the method may further include:

[0140] Comparing the mapping relationship with a predetermined standard mapping relationship; the standard mapping relationship is a correspondence between the antenna channel ID information of each antenna channel and the RF channel ID information of the RF channel to which each antenna channel is correctly connected;

[0141] In response to the mapping relationship being inconsistent with the standard mapping relationship, it is confirmed that there is a channel connection error in the base station antenna channel topology; or, in response to the mapping relationship being consistent with the standard mapping relationship, it is confirmed that there is no channel connection error in the base station antenna channel topology.

[0142] In the embodiment of the present disclosure, Figure 10 As shown, the following specific embodiments are given below:

[0143] The second RF channel of RRU1 is a 700 MHz channel, which is mistakenly connected to the 900 MHz antenna channel of antenna 1. The third RF channel of RRU1 is a 900 MHz channel, which is mistakenly connected to the 700 MHz antenna channel of antenna 1. At this time, after channel topology detection, the above specific errors can be determined based on the frequency band and channel number information contained in the antenna channel ID information in the tag signal.

[0144] The 5th RF channel in RRU2 is mistakenly connected to the 6th antenna channel of antenna 2, and the 6th RF channel in RRU2 is mistakenly connected to the 5th antenna channel of antenna 2. The 5th RF channel and 6th antenna channel in RRU2 and antenna 2 are co-frequency channels. At this time, after channel topology detection, the channel number information contained in the antenna channel ID information in the tag signal can be used to determine the above specific errors.

[0145] The eighth RF channel in RRU2 is incorrectly connected to the first port of antenna 3. Antenna 3 and RRU2 belong to different sectors, which indicates a misconnection of the channel between sectors. Channel topology detection can detect this error based on the antenna channel ID information in the tag signal, including the antenna device number, frequency band information, and channel number.

[0146] There is also a situation where the tag reader cannot read any returned tag signal. At this time, the RRU-antenna channel connection is abnormal or disconnected, resulting in the inability to complete signal transmission.

[0147] In the embodiment of the present disclosure, Figure 11 As shown, through the above solution, the base station antenna 100 and the RRU 200 transmit signals. After the RRU 200 obtains the antenna channel ID information of the antenna channel to which each RF channel is connected, the RRU 200 sends the antenna channel ID information to the BBU 300. The BBU 300 establishes a mapping relationship between the antenna channel ID information and the RF channel ID information, obtains the base station antenna channel topology, and sends the base station antenna channel topology to the network management system 400 for display. Through this embodiment, the base station antenna channel topology can be verified in real time at the physical layer, achieving high-precision, non-intrusive automatic detection of the base station antenna channel topology.

[0149] 1. Realize automated base station antenna channel topology detection and construction, avoiding manual detection and improving detection accuracy.

[0150] 2. The base station antenna channel topology detection system has a simple structure and low implementation cost.

[0151] 3. The base station antenna channel topology detection system can quickly and accurately complete the base station antenna channel topology detection and construction. The detection can be completed when the site is opened, making it easier for installers to correct errors in a timely manner.

[0152] 4. The base station antenna channel topology detection system relies on the coded information in the tag ID to mark the channel, which is more accurate and can provide more complete information. It can directly read the antenna number, frequency band and channel number connected to the RF channel.
