The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments that can be derived from the disclosure by one of ordinary skill in the art based on the embodiments in the disclosure are intended to be within the scope of the disclosure.
When the communication frequency of the ATG terminal and the ATG base station is the same as the frequency of the IMT base station area, that is, the ATG system (the system in which the ATG terminal communicates with the ATG base station) and the IMT system (the system in which the IMT base station provides communication service) perform the same-frequency networking, as shown in fig. 1, when the ATG terminal transmits an uplink signal from the aircraft to the ground ATG base station, a co-frequency interference signal will be generated to the uplink of the ground IMT base station, and since the coverage area range of the ATG terminal to the ground is very large, a large number of IMT base stations on the ground will receive the ATG terminal interference signal, which has a great influence on the performance of the IMT system. The disclosed embodiments provide an interference signal detection method, an interference signal detection device, an electronic device, a computer-readable storage medium, and a computer program product containing instructions to implement detection of an interference signal.
First, a method for detecting an interference signal according to an embodiment of the present disclosure will be described below. The method is applied to any electronic equipment which can provide interference signal detection service, such as a personal computer, a server and the like. The interference signal detection method provided by the embodiment of the present disclosure may be implemented by at least one of software, a hardware circuit, and a logic circuit provided in an electronic device.
As shown in fig. 2, fig. 2 provides an interference signal detection method for an IMT base station in the embodiment of the present disclosure, where the method includes:
s110, obtaining an allocation rule of ATG uplink resources; the allocation rule is used for determining the sub-carrier of the communication between the ATG base station and the ATG terminal; the signal frequency of the ATG base station communicating with the ATG terminal is at least partially the same as the signal frequency of the IMT base station,
s120, determining the frequency band of the subcarrier to be monitored based on the allocation rule to obtain the frequency band to be monitored;
and S130, detecting a frequency band to be monitored in an uplink signal of the ATG terminal to obtain a detection result of whether the IMT base station is subjected to uplink interference of the ATG terminal, wherein the IMT base station does not communicate with the IMT terminal through the frequency band to be monitored.
When the ATG base station allocates frequency resources for the ATG terminal and the IMT base station allocates frequency resources for the IMT terminal, the total frequency band owned by the terminal is divided into a plurality of frequency bands, each frequency band is also called a subcarrier, the subcarriers allocated to the corresponding terminal are determined from the subcarriers, and each terminal communicates with the corresponding base station based on the subcarriers allocated to the terminal. In order to determine whether the IMT base station is interfered by an uplink of the ATG terminal, the IMT base station needs to detect an uplink interference signal of the ATG terminal, and first, the IMT base station needs to determine a subcarrier used for detecting the uplink interference signal of the ATG terminal, specifically, the IMT base station first obtains an allocation rule of an ATG uplink resource, and then determines a frequency band of the subcarrier to be monitored in a total frequency band of the IMT base station based on the allocation rule of the ATG uplink resource to obtain a frequency band to be monitored, wherein the frequency band to be monitored is only used for detecting the uplink interference signal and is not used for the IMT base station to communicate with the IMT terminal, that is, the IMT base station does not allocate the frequency band to be monitored to the IMT terminal.
The IMT base station detects the frequency band to be monitored in the uplink signal of the ATG terminal, and the frequency band to be monitored is not allocated to the IMT terminal for use, so that the ATG terminal in the air can be judged once an interference signal exists on the frequency band to be monitored.
Optionally, the manner in which the IMT base station acquires the allocation rule of the ATG uplink resource may be that the ATG base station sends the allocation rule of the ATG uplink resource to the IMT base station, and specifically, the ATG base station may store attribute information of a neighboring base station thereof, where the attribute information includes identification information of the IMT base station, and when one ATG base station determines to provide a communication service for the ATG terminal, the ATG base station sends the allocation rule of the ATG uplink resource of itself to the neighboring base station. The allocation rule of ATG uplink resources may be allocated in the order of subcarrier frequency from high to low, or may be allocated in the order of subcarrier frequency from low to high.
Optionally, since the subcarriers to be monitored are only for detecting the uplink interference from the ATG terminal, the number of the subcarriers to be monitored is as small as possible, and more uplink frequency resources are allocated to the IMT terminal for use as possible.
And determining the frequency band of the subcarrier to be monitored based on the allocation rule of the ATG uplink resource to obtain the frequency band to be monitored, wherein after the frequency band to be monitored is obtained, the frequency band to be monitored is only used for detecting the frequency band to be monitored in the uplink signal of the ATG terminal, and the IMT base station does not allocate the frequency band to be monitored to the IMT terminal for communication, so that the detection result of whether the IMT base station is subjected to the uplink interference of the ATG terminal can be obtained.
In a possible embodiment, after the determining the frequency band of the subcarrier to be monitored based on the allocation rule and obtaining the frequency band to be monitored, the method further includes:
and removing the frequency band to be monitored from the frequency band allocated to the IMT terminal.
After the frequency band of the subcarrier to be monitored is determined, the frequency band to be monitored needs to be removed from the frequency band allocated to the IMT terminal, so that the IMT terminal is prevented from communicating by using the frequency band to be monitored, and the accuracy of detecting the interference signal is improved.
In a possible embodiment, the detecting the frequency band to be monitored in the uplink signal of the ATG terminal to obtain a detection result of whether the IMT base station is interfered by the uplink signal of the ATG terminal includes:
detecting a frequency band to be monitored in an uplink signal of the ATG terminal, and taking the detected signal as an uplink interference signal;
determining the strength and/or duration of an uplink interference signal;
determining that the IMT base station is subjected to uplink interference of the ATG terminal under the condition that the strength of the uplink interference signal exceeds a preset signal strength threshold and/or the duration exceeds a preset time length threshold; otherwise, determining that the IMT base station is not subjected to the uplink interference of the ATG terminal.
When a frequency band to be monitored in an uplink signal of an ATG terminal is detected, when the signal is detected, it is indicated that equipment communicates through the frequency band, at this time, an IMT base station can be basically subjected to uplink interference of the ATG terminal, in order to reduce detection errors, the strength and/or duration of the uplink interference signal can be determined first, a threshold value is set based on the strength and/or duration of the uplink interference signal, the IMT base station is determined to be subjected to the uplink interference of the ATG terminal based on the threshold value, and specifically, if the strength of the uplink interference signal exceeds a preset signal strength threshold value, the IMT base station can be determined to be subjected to the uplink interference of the ATG terminal; or, if the duration of the interference signals exceeds a preset time length threshold, determining that the IMT base station is subjected to uplink interference of the ATG terminal; or, if the strength of the uplink interference signal exceeds the preset signal strength threshold and the duration of the interference signal exceeds the preset time length threshold, it may be determined that the IMT base station is subjected to uplink interference from the ATG terminal. The preset signal strength threshold and the preset time length threshold may be set based on actual needs, and are not limited herein.
In a possible embodiment, the determining the frequency band of the sub-carrier to be monitored based on the allocation rule includes:
under the condition that the allocation rule of the ATG uplink resources is that the sub-carrier frequencies are allocated in sequence from high to low, determining the same frequency band of the ATG base station and the IMT base station to obtain a first frequency band, and taking the highest frequency sub-carrier in the first frequency band as the sub-carrier to be monitored;
and under the condition that the allocation rule of the ATG uplink resources is that the sub-carrier frequencies are allocated from low to high, determining the frequency bands of the ATG base station and the IMT base station which are the same, obtaining a first frequency band, and taking the lowest frequency sub-carrier in the first frequency band as the sub-carrier to be monitored.
When the frequencies of the ATG system and the IMT system are completely the same, the frequency band to be monitored of the IMT base station may be set at the initial position of the ATG uplink frequency resource allocation, that is, as shown in fig. 3, under the condition that the allocation rule of the ATG uplink resource is that allocation is performed in the order of subcarrier frequency from high to low, the highest frequency subcarrier is taken as the subcarrier to be monitored; and under the condition that the allocation rule of the ATG uplink resources is that the sub-carrier frequencies are allocated from low to high, taking the sub-carrier with the lowest frequency as the sub-carrier segment to be monitored.
When the frequency parts of the ATG system and the IMT system are the same, firstly determining the frequency band of the ATG base station which is the same as the frequency band of the IMT base station to obtain a first frequency band, when the allocation rule of the ATG uplink resource is that allocation is performed according to the sequence of subcarrier frequencies from high to low, taking the highest frequency subcarrier in the first frequency band as a subcarrier to be monitored, and when the allocation rule of the ATG uplink resource is that allocation is performed according to the sequence of subcarrier frequencies from low to high, taking the lowest frequency subcarrier in the first frequency band as the subcarrier to be monitored, so that when the IMT base station detects the frequency band to be monitored, the ATG terminal can be detected as long as the ATG terminal transmits an uplink signal.
The IMT base station measures the uplink interference in real time through the frequency band to be monitored, and the frequency band to be monitored is not distributed to the IMT terminal for use, so that the ATG terminal from the air can be judged once an interference signal exists on the frequency band to be monitored.
In a possible embodiment, the method further includes:
and under the condition that the IMT base station is determined to be subjected to uplink interference of the ATG terminal, allocating uplink subcarriers for the IMT terminal according to an allocation rule opposite to the allocation rule of the ATG uplink resources.
Because the uplink frequency resources of the IMT base station are sufficient, when the IMT base station determines to receive the uplink interference of the ATG terminal, the IMT base station may allocate uplink subcarriers to the IMT terminal according to an allocation rule opposite to the allocation rule of the ATG uplink resources, that is, when the allocation rule of the ATG uplink resources is to allocate the sub-carrier frequencies in order from high to low, the IMT base station allocates uplink subcarriers to the IMT terminal in the order of subcarrier frequencies from low to high, when the allocation rule of the ATG uplink resources is to allocate the sub-carrier frequencies in order from low to high, the IMT base station allocates uplink subcarriers to the IMT terminal in the order of subcarrier frequencies from high to low, and by following an allocation rule opposite to the allocation rule of ATG uplink resources, the possibility that the subcarriers allocated to the ATG terminal are the same as the subcarriers allocated to the IMT terminal can be reduced, so that the interference of uplink co-channel signals of the ATG terminal on the IMT base station can be avoided.
Further, under the condition that the IMT base station is determined not to be subjected to uplink interference of the ATG terminal, the IMT base station allocates uplink subcarriers to each accessed IMT terminal according to an uplink resource allocation mode set by the IMT base station.
Based on the foregoing method embodiment, an embodiment of the present disclosure further provides an interference signal detection apparatus, which is applied to an IMT base station, as shown in fig. 4, where fig. 4 is a schematic structural diagram of the interference signal detection apparatus provided in the embodiment of the present disclosure, and the apparatus includes:
