Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Currently, for the work of fault location and daily maintenance of a 5G distributed pico-base station, most of the works depend on manual field processing, which results in long maintenance period and low implementation efficiency, aiming at the problem, the invention provides a new distributed pico-base station interference location method, which adopts an intelligent maintenance technology, and fig. 1 is a schematic flow diagram of the distributed pico-base station interference location method provided by the invention, as shown in fig. 1, the method comprises the following steps:
s1, the BBU counts and obtains a cell level uplink interference value, and determines corresponding extended unit HUB equipment based on the cell level uplink interference value and in combination with system topology information;
the method is characterized in that interference monitoring is carried out from a BBU (base band unit) according to the structural characteristics of a 5G distributed pico-base station, the BBU is used as a core control unit of a base station core and used for carrying out centralized supervision on a radio remote unit, a centralized arrangement mode is usually adopted as a baseband signal processing unit, internal processing products and signals are used, and the base noise value of the system is confirmed by counting PRB (Physical Resource Block). The normal background noise value of the distributed pico-station system is-112 dBm, the normal background noise value is used as a reference, and the part higher than the reference background noise value can be considered as interference, and if the radio frequency combination of the lower-connection HUB unit is involved, the reference background noise value can be changed correspondingly.
The invention adopts BBU to detect the ascending interference value of cell level to obtain HUB interference value mapping table, then combines the system topology information to correspond the interference value to the corresponding optical port level device, namely the HUB device corresponding to the optical port lower link.
S2, the HUB device determines a PICO list of the abnormal interference remote unit by adopting a polling positioning detection method;
and further positioning the fault to a specific HUB device, and using an uplink interference value obtained by the BBU as an initial interference value, wherein the initial interference value is pushed to the corresponding HUB device by the BBU through a HUB interference value mapping table.
Because each HUB device can be connected with 8 PICO at most, the invention provides a polling positioning detection method, each PICO connected with the lower part is positioned one by one to obtain a plurality of real-time interference values, and a PICO uplink channel with abnormal interference is obtained by combining the comparison of the initial interference values to form an abnormal interference PICO list;
and S3, traversing the interference abnormal PICO list, positioning and acquiring an abnormal PICO uplink channel, and performing operation maintenance post-processing on the abnormal PICO uplink channel.
And according to the positioning result at the HUB equipment side, namely the obtained abnormal interference PICO list, carrying out interference post-processing on the BBU, further screening each PICO uplink channel with abnormal interference in the abnormal interference PICO list to obtain an interference source, isolating the interference source, and reporting, operating and maintaining the interference source.
It should be noted that, in the method for tracing the interference path to each module in the distributed pico-base station, as shown in fig. 2, cell-level interference detection is started on the BBU side, an interference value abnormality of a cell 1 is obtained, uplink background noise detection of an optical port level is started, interference is detected in HUB21 connected downstream of an optical port 2 therein, 8 pico channels connected downstream of a HUB21 are further checked, the interference range is narrowed to the first 4 pico ports, that is, P211 to P214, a main interference source is finally checked to be the pico uplink channel corresponding to the P211 port, and finally the P211 port is isolated and is reported for operation and maintenance.
The invention traces the source of the interference path to each module in the distributed pico-base station, checks layer by layer to obtain the fault point with the interference source, and carries out operation maintenance treatment on the fault point in time, thereby reducing the influence generated by the fault to the minimum and achieving the effect of intelligent maintenance.
Based on the above embodiment, the method step S1 is preceded by:
determining a cell-level uplink background noise reference value based on the system reference background noise value and the HUB radio frequency combination mode;
and acquiring a real-time uplink background noise value of each cell, and determining the difference between the real-time uplink background noise value and the cell level uplink background noise reference value as the cell level uplink interference value.
Specifically, the BBU needs to calculate an uplink base noise reference value of the system first, and calculate the uplink base noise reference value of the system according to the system reference base noise value and the radio frequency combining mode on the HUB, where if the system reference base noise value is-112 dBm and the radio frequency combining mode on the HUB is radio frequency 4-in-1, the system uplink base noise reference value is-112 + 6-106 dBm.
And the BBU detects uplink base noise values of all cells at regular time, and the difference between the real-time uplink base noise value and the system uplink base noise reference value is a cell-level uplink interference value.
The uplink interference value is obtained through the difference between the uplink background noise value obtained by BBU real-time detection and the system uplink background noise reference value, the real-time interference condition of the system can be effectively detected, and accurate interference value reference data is provided for implementing interference positioning.
Based on any of the above embodiments, step S1 of the method specifically includes:
if the BBU judges that the cell level uplink interference value is larger than an uplink interference alarm threshold, triggering and starting optical port level uplink background noise detection;
and acquiring HUB number information in common public radio interface CPRI data, and determining the corresponding HUB equipment based on the cell-level uplink interference value and the HUB number information.
Specifically, the BBU interference detection routing flow is shown in fig. 3:
after the uplink interference value is obtained, the BBU starts to implement interference detection, the BBU refreshes the uplink interference value at regular time, and the uplink interference value is 0 under normal conditions
The difference value between the uplink background noise value and the uplink interference value of the cell is detected at fixed time, if the difference value exceeds an uplink interference alarm threshold value (the detection precision and other factors are considered here, the threshold value is generally set to 3dB), the system is judged to have uplink interference, interference route detection is triggered, namely optical interface level uplink background noise detection is started, the optical interface level background noise information detection consumes operation resources compared with cell level interference detection, and only cell level interference detection is started under normal conditions, so that the starting is carried out when the triggering condition is met.
The method includes the steps of synchronously recording corresponding HUB number information in CPRI (Common Public Radio Interface) data, mapping the number of an optical port of a corresponding BBU and the number of a HUB in a system by the HUB number information, and storing an interference value and corresponding HUB number information into a HUB interference value mapping table.
And the BBU pushes the HUB interference value mapping table to the corresponding HUB equipment, and starts HUB interference positioning.
According to the invention, the BBU judges whether the uplink base noise detection of the corresponding optical port is started according to the fact that whether the uplink interference value exceeds the threshold value, so that the HUB equipment with interference can be accurately positioned, the automatic pushing of interference information is realized, and the interference source in the HUB equipment is conveniently further searched out.
Based on any of the above embodiments, acquiring HUB number information in common public radio interface CPRI data, and determining the HUB interference value mapping table based on the uplink interference value and the HUB number information, and then further including:
and adding the corresponding HUB equipment to a HUB interference value mapping table, and updating the HUB interference value mapping table to the system topology information, wherein the system topology information comprises a base band processing unit BBU lower optical connection port number, a lower optical connection port connection HUB number and a HUB connection remote radio unit RRU number.
Optionally, after the HUB interference positioning is started, the BBU synchronously updates an interference value corresponding to the HUB to a system topology information table, where the system topology information table includes a BBU lower optical interface number, a HUB number corresponding to the connection, and an RRU number to which the HUB is connected.
The invention synchronously updates the system topology information table when obtaining the real-time interference information of the system, is convenient for operation and maintenance personnel to know the latest system topology networking condition in time, and embodies the real-time property and the convenience of intelligent maintenance.
Based on any of the above embodiments, step S2 of the method specifically includes:
dividing the lower ports of the HUB equipment into two groups;
closing the PICO uplink channels of the first group of downlink ports, acquiring a first current interference value, traversing the interference values of the second group of downlink ports if the difference between the first current interference value and the cell-level uplink interference value is judged to be not greater than an uplink interference alarm threshold value, and traversing the interference values of the first group of downlink ports if the difference is not greater than the uplink interference alarm threshold value, otherwise, determining all the PICO uplink channels with interference;
closing any PICO uplink channel with interference, acquiring a second current interference value, if the difference between the second current interference value and the cell level uplink interference value is judged to be not greater than the uplink interference alarm threshold value, determining that the interference of any PICO uplink channel with interference is normal, otherwise determining that the interference of any PICO uplink channel with interference is abnormal, circularly traversing all the PICO uplink channels with interference, and acquiring the serial number of the PICO uplink channel with abnormal interference;
and determining the abnormal interference PICO list based on the abnormal interference PICO uplink channel number.
Specifically, the HUB interference positioning process is shown in fig. 4:
and after receiving the interference detection starting message sent by the BBU, the HUB also receives the corresponding interference value. The interference value at this time is defined as an initial interference value. The invention designs a polling positioning detection method aiming at a HUB interference positioning process, 8 ports are connected below the HUB, a binary method is firstly used for positioning a rough area, and then PRRUs of corresponding areas are traversed.
Firstly, dividing 8 ports of a HUB upper link and a HUB lower link into two groups in sequence, and closing uplink channels of PICO (peripherally inserted Central authorities) of the first 4 ports, namely a first group of lower link ports;
informing the BBU to acquire information of a current HUB and interference value mapping table, comparing the acquired first current interference value with the initial interference value, and if the first current interference value is unchanged (namely smaller than an uplink interference alarm threshold), traversing the interference values of the 4 subsequent ports, namely a second group of downlink ports; if the interference value is normal, the interference values of the first 4 ports are traversed. Otherwise, traversing all pico ports;
further, according to the range determined in the above steps, closing the Nth pico uplink channel;
informing a BBU to acquire current HUB interference value mapping table information, comparing a second current interference value acquired after an Nth pico uplink channel is closed with an initial interference value, and marking that the corresponding pico interference is normal if the second current interference value is not changed (namely is smaller than an uplink interference alarm threshold value); if the difference value between the initial interference value and the second current interference value is larger than the uplink interference alarm threshold value, marking the corresponding pico interference abnormality, and circularly traversing all the pico;
and after the HUB traverses all the PICO, acquiring the serial number of the abnormal interference PICO uplink channel, thereby obtaining an abnormal interference PICO list, replying a HUB detection completion message to the BBU, and replying the condition of the interference value after the close of each PICO carried by the HUB.
At this time, after the BBU receives the message that the HUB detection is completed, the interference post-processing flow is started.
According to the invention, the polling positioning detection method is adopted to screen and investigate the PICO port of the HUB downlink to obtain the interference abnormal PICO list, so that the BBU can be conveniently subjected to subsequent operation maintenance treatment, and the method has the characteristic of high accuracy, and reflects the high efficiency of intelligent operation and maintenance compared with manual inspection.
Based on any of the above embodiments, step S3 of the method specifically includes:
closing any one corresponding abnormal interference PICO uplink channel in the abnormal interference PICO list;
acquiring a current interference value of a cell, and if the current interference value of the cell is judged to be smaller than an uplink interference alarm threshold, determining any abnormal interference PICO uplink channel as a main interference source;
and traversing all the abnormal interference PICO uplink channels in the abnormal interference PICO list until the current interference value of the cell is recovered to be normal, and performing operation maintenance post-processing on all the abnormal interference PICO uplink channels.
Specifically, the BBU interference post-processing flow is shown in fig. 5:
after receiving the HUB detection completion message, the BBU starts to judge the condition of each PICO interference value reported by all HUBs, and all the PICO displaying abnormal interference under each HUB form an abnormal interference PICO list;
firstly, updating an interference abnormity PICO list in a system, and closing an Nth interference abnormity PICO uplink channel;
detecting the current interference value of the cell, if the current interference value is recovered to be normal, judging that the pico is a main interference source, closing a corresponding pico channel, reporting a pico uplink interference abnormal alarm, and reporting operation maintenance processing;
further, in order to find out all interference sources, the BBU traverses the interference abnormal PICO list, and repeats the above operations until the uplink interference value returns to normal.
According to the method, the main interference source of the system is further screened according to the interference abnormal PICO list in the HUB through BBU interference post-processing, and accurate interference positioning is realized.
Based on any of the above embodiments, traversing all the abnormal interference PICO uplink channels in the abnormal interference PICO list until the current interference value of the cell returns to normal, performing operation maintenance post-processing on all the abnormal interference PICO uplink channels, and then further including:
and closing the optical port level uplink background noise detection, and updating the interference value information in the system topology information table.
Optionally, after the BBU completes the interference post-processing flow, the optical port uplink background noise detection is also turned off, the interference value information of each device in the system topology information table is updated, and an alarm is prompted, and post-processing of operation and maintenance is reported.
Here, since the optical interface level uplink background noise detection consumes system resources comparatively, after a specific interference source is detected, the BBU performs shutdown processing, thereby realizing closed-loop processing of the detection flow.
According to the BBU interference post-processing method, the main interference source is further obtained by screening according to the HUB interference detection result, the interference detection process is subjected to closed-loop processing, the positioning is accurate, the efficiency is high, and the operation and maintenance cost is saved.
