[0058] With the evolution of communication technology, modern base station antenna systems exhibit the following development trends: within the same antenna, the antenna port density is significantly improved, and multi-frequency multi-standard antenna units are integrated and fused. According to statistics, the proportion of current multi-frequency composite antennas is more than 70%. At the same time, the deployment density of RRUs (Remote Radio Unit, radio frequency remote unit) increases by 3 times compared with the 4G (fourth generation communication technology) period, and the number of single base station RRUs can reach 12-24. The sky surface equipment supports multi-dimensional coverage modes such as three sectors and six sectors.

[0059] - Cross-band misconnection; for example, 900MHz (megahertz) port misconnection with 1.8GHz RRU;

[0060] - Sector orientation misplacement; for example, A sector port misconnection with B sector port;

[0061] - Polarization direction confusion; for example, ±45° dual-polarized antenna cross misconnection;

Each path of the M-select-1 switch 2012 is respectively interconnected with one channel coupler 203. The channel coupler 203 functions to couple the interrogation signal transmitted from the side of the M-select-1 switch 2012 to the radio frequency transceiver 204 of the RRU.

The control unit of the information reading and processing unit 201 can control the tag reader 2011 to generate an interrogation signal, and send the interrogation signal to the target antenna channel connected to the target radio frequency channel through the target radio frequency channel when one target radio frequency channel is selected each time. Therefore, each time the target tag module connected to the target antenna channel is activated by the interrogation signal, a tag signal will be 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 analyzes each returned tag signal to obtain the antenna channel ID information returned each time.

[0107] receiving, by a target antenna radio frequency input port corresponding to the target antenna channel, an inquiry signal sent by a target radio transceiver port corresponding to the target antenna channel; the inquiry signal is obtained by a target channel coupler corresponding to the target radio transceiver port from a target radio frequency channel selected based on an M-to-1 switch;

[0108] The target antenna radio frequency input port transmits the inquiry signal to a 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 radio transceiver port 204 through the i th channel coupler 203, it can first be transmitted to the corresponding i th antenna channel through the radio frequency 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 a target tag corresponding to the target antenna channel to activate the target tag.

[0111] In the embodiment of the present disclosure, coupling the inquiry signal to the target tag corresponding to the target antenna channel to activate the target tag can comprise:

[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 part of the inquiry signal sent by the RRU radio frequency 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 transmit another part of the inquiry signal to the connected target antenna channel through the antenna radio frequency output port 1012.

[0114] In the embodiment of the present disclosure, for example, at the i-th antenna channel, the interrogation signal is coupled out a part 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 interrogation signal.

[0115] In the embodiment of the present disclosure, when the interrogation signal is sent, appropriate interrogation signal strength and signal coupling strength need to be set to ensure that the tag module 1014 can be activated; at the same time, the isolation degree between the signal coupling module 1013 and the remaining tag modules 1014 (i.e. non-target tag modules) needs to be ensured to avoid activating other tag modules 1014, thereby causing the reflection response of multiple tag modules 1014, and avoiding signal interference to cause ID identification confusion.

[0116] In the embodiment of the present disclosure, the tag module 1014 can be a passive tag, at this time, a battery will not be needed, and the interrogation signal can provide energy to activate to generate a reflection signal (i.e. tag signal).

[0117] S33, the target tag returns the antenna channel identity ID information of the target antenna channel to the RRU through 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 through the target radio frequency channel, which can include:

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

[0120] In the 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 radio frequency input port through the target signal coupling module corresponding to the target tag module; the target antenna radio frequency input port transmits the tag signal to the target radio frequency 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 to the tag reader through the corresponding target channel coupler, the M-to-1 switch and the corresponding target switch path in the target antenna radio frequency transceiver port.

[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 the information to the information reading and processing unit 201 in the RRU 200 in the form of a modulated radio frequency carrier.

[0122] In the embodiments of the present disclosure, for example, the tag signal is coupled to the i-th antenna radio frequency input port through the i-th signal coupling module 1013, further transmitted back to the i-th radio frequency transceiver port of the RRU through the radio frequency 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 radio frequency transceiver port, and further returned to the tag reader 2011 in the RRU 200 and received and parsed by the tag reader to obtain the antenna channel ID information corresponding to the i-th antenna channel.

[0123] In the embodiments of the present disclosure, in the case that the antenna channel 102 and the radio frequency 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, in the case that the antenna channel 102 and the radio frequency 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 embodiments of the present disclosure, based on the above scheme, each path of the M-to-1 switch 2012 is sequentially turned on, and the above process is repeated, so that the parsing of the M-path antenna channel ID information can be completed.

[0125] In the embodiments of the present disclosure, the tag reader 2011 can send the parsed antenna channel ID information and the radio frequency channel ID information corresponding to the radio frequency channel sending the inquiry signal to the BBU, so as to determine the actual base station antenna channel topology through the BBU.

[0126] The embodiments of the present disclosure also provide a base station antenna channel topology detection method applied to a baseband processing unit BBU, as shown in the following Figure 9 The method comprises steps S41-S42:

[0127] S41, obtaining antenna channel identity ID information sent by the RRU and radio frequency channel ID information corresponding to the radio frequency channel sending the inquiry signal; the antenna channel ID information is the return signal of the antenna channel based on the inquiry information received by the RRU based on the channel topology detection instruction and sent by the RRU to the antenna channel corresponding to each radio frequency channel of the RRU in sequence.

[0128] In the embodiments of the present disclosure, the BBU can receive the antenna channel ID information and the radio frequency channel ID information corresponding to the radio frequency channel sending the inquiry signal sent by the tag reader 2011 of the RRU.

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

[0130] In the embodiment of the present disclosure, the embodiment scheme can be applied to a mapping relationship construction unit 301 in the BBU 300, which can be implemented by a processor of the BBU 300.

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

[0132] Corresponding storage of the antenna channel ID information returned by the antenna channel each time and the radio frequency channel ID information of the radio frequency channel sending the inquiry signal at the time;

[0133] Corresponding relationship between the corresponding stored antenna channel ID information and the radio frequency channel ID information as the mapping relationship.

[0134] In the embodiment of the present disclosure, the BBU 300 can set a corresponding list or a data matrix to correspondingly store the antenna channel ID information received each time and the radio frequency channel ID information of the corresponding connected radio frequency channel, so as to obtain the mapping relationship between the antenna channel ID information of all antenna channels and the radio frequency channel ID information of the corresponding connected radio frequency channel.

[0135] In the embodiment of the present disclosure, the BBU 300 can send the mapping relationship to the network management 400 to present the mapping relationship through the network management 400, so as to realize the establishment of the mapping relationship between the antenna channel ID information and the radio frequency channel ID information.

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

[0137] Establishing a corresponding relationship between the device information of the electrically adjustable module bound with the antenna channel ID information and the radio frequency channel ID information; the electrically adjustable module is used to adjust the antenna beam parameter of the bound antenna channel.

[0138] In the embodiment of the present disclosure, by corresponding the device information (such as device number) of the electrically adjustable module bound with the antenna channel ID information and the cell ID (or the radio frequency channel ID information), subsequent intelligent network optimization is facilitated.

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

[0140] Comparison of the mapping relationship with a pre-determined standard mapping relationship; the standard mapping relationship is the corresponding relationship between the antenna channel ID information of each antenna channel and the radio frequency channel ID information of the radio frequency channel correctly connected with each antenna channel;

[0141] In response to the mapping relationship being inconsistent with the standard mapping relationship, it is confirmed that the base station antenna channel topology has a channel connection error; or in response to the mapping relationship being consistent with the standard mapping relationship, it is confirmed that the base station antenna channel topology does not have a channel connection error.

[0142] In the embodiment of the present disclosure, as shown in Figure 10 The following specific embodiments are given below.

[0143] The second radio frequency channel of the RRU1 is a 700M channel, which is incorrectly connected to the 900M antenna channel of the antenna 1. The third radio frequency channel of the RRU1 is a 900M channel, which is incorrectly connected to the 700M antenna channel of the antenna 1. At this time, through channel topology detection, the above specific error can be judged by the frequency band and channel number information contained in the antenna channel ID information in the tag signal.

[0144] The fifth radio frequency channel in the RRU2 is incorrectly connected to the sixth antenna channel of the antenna 2. The sixth radio frequency channel in the RRU2 is incorrectly connected to the fifth antenna channel of the antenna 2. The fifth radio frequency channel in the RRU2 and the sixth antenna channel in the antenna 2 are the same frequency channel. At this time, through channel topology detection, the above specific error can be judged by the channel number information contained in the antenna channel ID information in the tag signal.

[0145] The eighth radio frequency channel in the RRU2 is incorrectly connected to the first port in the antenna 3. The antenna 3 and the RRU2 belong to different sectors, which belongs to the incorrect connection of channels between sectors. At this time, through channel topology detection, the above specific error can be judged by the antenna device number, frequency band information, and channel number contained in the antenna channel ID information in the tag signal.

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

After the RRU 200 obtains the antenna channel ID information of the antenna channel connected by each radio frequency channel, the RRU 200 sends the antenna channel ID information to the BBU 300. The BBU 300 establishes the mapping relationship between the antenna channel ID information and the radio frequency channel ID information, obtains the base station antenna channel topology, and sends the base station antenna channel topology to the network management 400 for display. Through the embodiment scheme, real-time connection verification of the base station antenna channel topology can be realized from the physical layer, and high-precision, non-intrusive automatic detection of the base station antenna channel topology can be realized.
