[0002] In the wireless communication network architecture, small base stations are key devices for flexible deployment and efficient coverage. The stability and reliability of their performance are directly related to the operational quality of the entire network. Among them, the antenna presence detection function of the small base station antenna port is one of the core indicators for evaluating the operating status of the equipment, which is crucial to ensuring the normal operation of the small base station and the continuity of network coverage. This function prevents signal interruption and service quality degradation caused by antenna detachment or poor connection by monitoring the connection status of the antenna interface in real time, that is, whether the antenna is correctly installed and effectively connected to the base station unit.

[0003] Traditionally, whether it is a large base station or a small base station, in order to realize the antenna port in-place detection function, it is necessary to rely on complex hardware design, especially integrating forward feedback circuits on the circuit board. Although this design can effectively achieve the detection purpose, it undoubtedly increases the design complexity and manufacturing cost of the product, limiting the economic efficiency and market competitiveness of the equipment. Summary of the invention

The antenna presence detection is achieved by utilizing a receiving path without adding additional hardware modules, thereby simplifying the hardware design and reducing the manufacturing cost, while maintaining efficient and accurate detection capabilities.

[0005] A first aspect of the present invention provides a method for monitoring a small base station antenna in situ, comprising:

[0006] The external signal received by the antenna is obtained and amplified to obtain an amplified signal; the transceiver receives and amplifies the amplified signal and then sends it to the DFE processing chip;

[0017] Furthermore, the initial power of the signal sent by the transceiver when the antenna is not in place is calculated by the following formula:

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 1 As shown, the first embodiment of the present invention provides a method for monitoring the presence of a small base station antenna, comprising the following steps S11 to S12:

[0035] S11, obtaining an external signal received by the antenna and amplifying it to obtain an amplified signal; the transceiver receives and amplifies the amplified signal, and then sends it to the DFE processing chip;

[0036] S12, the DFE processing chip continues to receive the signal sent by the transceiver, calculates the average power of the signal, and compares it with the initial power of the signal sent by the transceiver when the antenna is not in place, to determine whether the antenna is in place.

[0037] In step S11, when the small base station is in normal working state, the receiving path remains open and the antenna continues to receive signals from the external environment. These signals are amplified by the amplification function module to ensure that the signal strength is sufficient for subsequent processing. By amplifying the signal, the strength and quality of the signal are improved, providing a reliable guarantee for subsequent reception and processing. The amplified signal is sent to the transceiver, which further processes the signal and sends it to the DFE processing chip. The DFE processing chip is the core of signal processing and is responsible for further amplification, filtering, demodulation and other processing of the signal.

[0038] In step S12, the DFE processing chip detects the DFE average power of the receiving path segment in a loop. Since the signal strength received by the antenna is directly related to whether the antenna is in place, it is possible to determine whether the antenna is in place by detecting the power. Specifically, by calculating the average power of the signal and comparing it with the initial power of the signal sent by the transceiver when the antenna is not in place, it is possible to determine whether the antenna is in place. By real-time monitoring of the power of the receiving path, it is possible to promptly detect whether the antenna is in place or working abnormally, so as to promptly report the alarm information to avoid affecting the normal operation of the small base station.

[0039] This method determines the antenna's presence and working status by real-time monitoring of the power of the receiving path, with high accuracy and reliability. By timely discovering and reporting antenna anomalies, it can ensure the normal operation of the small base station and improve the stability and reliability of the system.

[0040] Furthermore, in step S11, the external signal received by the antenna is obtained and amplified to obtain an amplified signal, including the following steps S111 to S113:

[0041] S111, obtaining an external signal received by the antenna;

[0042] S112, sending the external signal to an amplifier, wherein the amplifier includes a low noise amplifier;

[0043] S113: After receiving the external signal, the amplifier amplifies the external signal and sends it to the transceiver.

[0044] In step S111, the antenna, as the starting point of signal reception, is responsible for capturing wireless signals from the external environment. These signals may include various types of information such as voice, data, and images, which are transmitted through the air and received by the antenna.

[0045] In step S112, the acquired external signal is sent to an amplifier for processing. The amplifier here specifically refers to a device including a low noise amplifier (LNA). The main function of the low noise amplifier is to amplify weak signals while minimizing the introduction of noise to ensure the clarity and quality of the signal.

[0046] In step S113, inside the amplifier, the received external signal is amplified by the low noise amplifier, and the signal strength is significantly improved. Subsequently, the amplified signal is sent to the transceiver for subsequent signal amplification processing and other operations.

[0047] By amplifying the signal, the signal strength and quality are improved, providing reliable guarantee for subsequent reception and processing.

[0048] Further, in step S12, the DFE processing chip continuously receives the signal sent by the transceiver, and calculates the average power of the signal, and compares it with the initial power of the signal sent by the transceiver when the antenna is not in place, to determine whether the antenna is in place, including the following steps S121 to S123:

[0049] S121, the DFE processing chip obtains the initial power of the signal sent by the transceiver when the antenna is not in place;

[0050] S122, the DFE processing chip continues to receive the signal sent by the transceiver, and calculates the average power of the signal;

[0051] S123. The DFE processing chip compares the initial power with the average power. If the average power is greater than the initial power, it is determined that the antenna is in place; otherwise, it is determined that the antenna is not in place.

[0052] In step S121, the DFE processing chip first obtains and records the initial power value of the signal sent by the transceiver when the antenna is not in place. The initial power represents the power level of the signal sent by the transceiver when there is no antenna connected or the antenna fails.

[0053] The initial power is calculated by the following formula:

[0054] P=-174+G+NF

[0055] Wherein, P represents the initial power of the signal sent by the transceiver when the antenna is not in place; G represents the gain; and NF represents the noise factor.

[0056] In step S122, the DFE processing chip continues to receive signals from the transceiver. In order to accurately determine the antenna's in-place status, the chip calculates the average power of the signal received over a period of time. This average power value can more stably reflect the current signal strength and reduce the impact of instantaneous fluctuations on the judgment result.

[0057] In step S123, the DFE processing chip compares the calculated average power with the initial power obtained in step S121. If the average power is greater than the initial power, it means that the antenna has been correctly connected and is effectively receiving external signals, so the antenna is judged to be in place. On the contrary, if the average power is less than or equal to the initial power, it means that the antenna is not connected or failed, so the antenna is judged to be out of place.

[0058] This method determines the antenna's presence and working status by real-time monitoring of the power of the receiving path, with high accuracy and reliability. By timely discovering and reporting antenna anomalies, it can ensure the normal operation of small base stations, improve the stability and reliability of the system, and provide strong support for real-time monitoring of antenna status and troubleshooting.

[0059] like Figure 2 As shown, the second embodiment of the present invention provides a small base station antenna in-situ monitoring device, including the following modules:

[0060] Receiving module 21: used to obtain the external signal received by the antenna and amplify it to obtain an amplified signal; the transceiver receives and amplifies the amplified signal and then sends it to the DFE processing chip;

[0061] The judgment module 22 is used to enable the DFE processing chip to continuously receive the signal sent by the transceiver, and calculate the average power of the signal, and compare it with the initial power of the signal sent by the transceiver when the antenna is not in place, so as to judge whether the antenna is in place.

[0062] See Figure 3 A specific embodiment provided by the present invention discloses a small base station, including a device for monitoring antenna presence.

[0063] In this embodiment, all components of the small base station are functional modules that are indispensable for the operation of the product. It should be noted that it does not introduce any additional monitoring circuits to implement the antenna presence monitoring function, but instead uses the existing components of the product to implement the antenna presence monitoring function.

[0064] In the field of communications, whether it is a traditional macro base station or a small base station, it is crucial to monitor the antenna status. Traditionally, this function is usually achieved by designing a forward feedback circuit on the circuit board, such as Figure 4As shown in the schematic diagram, this solution relies on the transmit path (TX link) and a complex feedback loop for monitoring, which not only increases the manufacturing cost of the product, but also makes the design process more cumbersome.

[0065] In contrast, Figure 3 The embodiment of the present invention shown is particularly concise and efficient. It only uses the receiving path (RX link) as the monitoring channel, does not add any additional components, and completely relies on the necessary components built into the product, thereby effectively reducing costs.

[0066] Specifically, this embodiment discloses a small base station, including a device for monitoring antenna presence, wherein the device includes the following modules:

[0067] Receiving module 21: used to obtain the external signal received by the antenna and amplify it to obtain an amplified signal; the transceiver receives and amplifies the amplified signal and then sends it to the DFE processing chip;

[0068] The judgment module 22 is used to enable the DFE processing chip to continuously receive the signal sent by the transceiver, and calculate the average power of the signal, and compare it with the initial power of the signal sent by the transceiver when the antenna is not in place, so as to judge whether the antenna is in place.

[0069] It should be noted that the initial power is calculated by the following formula:

[0070] P=-174+G+NF

[0071] Wherein, P represents the initial power of the signal sent by the transceiver when the antenna is not in place; G represents the gain; and NF represents the noise factor.

[0072] In this product, the initial power P when no antenna is in place corresponds to the typical rssi value of dfe is -40dbFS. Based on this feature, the calculated dfe average power is monitored in real time to determine whether the antenna is in place. When the antenna is not in place, the in-place status alarm is reported to the application layer.

[0073] A third aspect of the present invention provides an electronic device, including: a processor and a memory;

[0074] The memory is used to store computer-executable instructions;

[0075] The processor is used to execute the computer-executable instructions stored in the memory, so that the electronic device executes the small base station antenna in-place monitoring method as described above.

[0076] A fourth aspect of the present invention provides a computer-readable storage medium for storing instructions or computer programs; when the instructions or the computer program are executed, a method for monitoring the presence of a small base station antenna as described above is implemented.

[0077] Compared with the prior art, the present invention has the following beneficial effects:

[0078] The embodiment of the present invention directly utilizes the inherent characteristics of signal power in the receiving path, monitors and calculates the average power after amplifying the signal, and compares it with the initial power when there is no antenna to determine whether the antenna is in place. Intelligent detection of the antenna in place status is achieved. This design does not require additional monitoring components, which not only simplifies the product architecture, but also greatly reduces system complexity and manufacturing costs, making small base stations more economical and efficient while maintaining high performance.

[0079] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
