Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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.
At present, for the overlapping coverage problem, a cell with poor quality is generally found according to Key Performance Indicators (KPIs), the overlapping coverage cell is judged by manually analyzing an MR report or a drive test, and then the problem of same frequency interference is solved through the experience of network optimization personnel.
In view of this, the present application provides a method and an apparatus for processing co-frequency interference, which determine whether a co-frequency overlay neighboring cell needs to be processed according to key KPI indicator information, and process the co-frequency overlay neighboring cell according to a certain policy when determining to process the co-frequency overlay neighboring cell, so as to reduce co-frequency interference of the co-frequency overlay neighboring cell to a serving cell.
It is to be understood that the terms "first," "second," and the like in the following description are used for descriptive purposes only and are not to be construed as indicating or implying relative importance, nor order.
Fig. 1 is a flowchart of a method for processing co-channel interference according to an embodiment of the present application, referring to fig. 1, the method includes:
s101: and acquiring network evaluation parameter information of the serving cell and an overlapping coverage adjacent cell of the serving cell.
In this embodiment, the network evaluation parameter information may include: at least one of a radio access rate, a radio drop rate, and a reference signal received power, RSRQ, of the serving cell.
S102: and if the network evaluation parameter information meets the preset condition, determining to process the overlapped covered adjacent cells.
In the embodiment of the application, if the same-frequency covering adjacent cell influences the network KPI, the same-frequency covering adjacent cell is determined to be processed. In a possible implementation manner, when the network evaluation parameter information meets the set condition, it may be determined that there is severe overlapping coverage between the local cell and the neighboring cells with the same frequency, and the network quality is affected.
That is, if the RSRQ of the serving cell is less than or equal to a first threshold, the radio access rate is less than or equal to a second threshold, and the radio drop rate is greater than or equal to a third threshold, it is determined to process the overlapping coverage neighboring cell.
It can be understood that, if the RSRQ of the serving cell is greater than the first threshold, the radio access rate is greater than the second threshold, and the radio drop rate is less than the third threshold, the overlapping coverage neighboring cells are not processed.
For convenience of description, the threshold Q1 of RSRQ is denoted as "first threshold", the threshold Q2 of radio call completing rate is denoted as "second threshold", and the threshold of radio drop rate is denoted as "third threshold".
According to the method and the device, the overlapped coverage adjacent cells are monitored through network evaluation parameter information, and the overlapped coverage adjacent cells can be processed in time, so that co-channel interference is reduced, i.e. the co-channel interference can be interfered in time, and the perception influence on users is reduced.
S103: and processing the same frequency interference of the overlapped covering adjacent cell to the service cell according to the processing strategy of the overlapped covering adjacent cell.
The above-mentioned step S103 will be described in detail below.
In this embodiment of the present application, the processing policy for overlapping coverage neighboring cells at least includes one of the following policies: and checking Physical Cell Identity (PCI), adjusting frequency points and adjusting the power of Cell Reference Signals (CRS).
In specific implementation, the following three modes can be included:
(1) and determining whether the overlapped covering adjacent cell has the same-frequency PCI module three interference or not according to the PCI, and if so, allocating a new PCI for the overlapped covering adjacent cell.
When the overlapped adjacent cells are processed, PCI check can be carried out to judge whether the same-frequency PCI module three interference exists in a certain coverage area, if so, new PCI is automatically allocated, and if not, the processing can be carried out according to the mode (2).
(2) And if the overlapped covering adjacent cell does not have the same-frequency PCI (peripheral component interconnect) modulo three-interference, the frequency point of the overlapped covering adjacent cell can be adjusted.
If the problem of co-channel interference is not solved after PCI checking, the frequency point can be adjusted or replaced, and if the frequency point cannot be replaced or the frequency point still has a problem after replacement, the method (3) can be executed.
In this way, since adjusting the frequency point may cause new adjacent cell interference with the same frequency, multiple adjustments may be performed to adjust to the most suitable frequency point, that is, the frequency point with the minimum adjacent frequency interference.
(3) And sending prompt information to the network manager, wherein the prompt information is used for prompting the network manager to adjust the CRS power of the overlapped adjacent cells.
In a possible implementation, when the former two ways can not be solved, the network manager can report the result to the network manager, and the network manager performs operation of reducing the power of the CRS on the adjacent regions with the same frequency and the highest overlapping coverage rate in a manual adjustment way.
It should be noted that the priority order of the above three modes is: (1) < 2 > (3).
Optionally, before obtaining the overlapping coverage neighboring cell, the method further includes:
and acquiring signal parameter information reported by the terminal, and determining the overlapped coverage adjacent cell according to the signal parameter information.
Wherein the signal parameter information may include at least one of TD-LTE serving cell reference signal received power, RSRP (mr. ltescrsrp), serving cell reference signal received quality, RSRQ (mr. ltescrsrq), intra-frequency neighbor RSRP (mr. ltencncrsrp), and intra-frequency neighbor RSRQ (mr. ltencncrsrq).
And counting MR reports in one period or a plurality of periods aiming at a certain same-frequency adjacent cell, and determining the same-frequency adjacent cell in one period or a plurality of periods as an overlapping coverage adjacent cell of the service cell if the following conditions are met.
Specifically, when the serving cell reference signal received power RSRP (mr. ltecscrsrp) and the same-frequency neighboring cell reference signal received quality RSRP (mr. ltecncrsrp) are within 6dB, and the serving cell reference signal received power RSRP (mr. ltecscrsrp) is greater than-110 dBm, it is determined that the same-frequency neighboring cell satisfies the overlapping coverage condition.
Optionally, the overlapping coverage rate of the co-frequency neighboring cell may be determined according to a ratio of the number of samples satisfying overlapping coverage by the co-frequency neighboring cell to the total number of samples of RSRP (mr. lterncrrsrp) of all reported co-frequency neighboring cells of the neighboring cell.
It should be understood that each same-frequency neighboring cell can be understood as a sample point, and the ratio of the number of sample points satisfying overlapping coverage to the total number of sample points is understood as the proportion of samples satisfying overlapping coverage, that is, the overlapping coverage rate of the same-frequency neighboring cells. For example, if the number of samples of the same-frequency neighboring cell that satisfy the overlapping coverage is M, and the total number of samples of all the neighboring cells that report the RSRP of the same-frequency neighboring cell is N, the overlapping coverage rate Q is M/N.
If the overlapping coverage rate of the same-frequency adjacent cells is greater than a set threshold value, for example, greater than N1, all the same-frequency adjacent cells meeting the overlapping coverage can be obtained, and the overlapping coverage adjacent cells are placed in a list.
In the embodiment of the application, data such as reference signal receiving power of a serving cell and a co-frequency adjacent cell of an MR server can be periodically monitored, when an overlapping coverage condition is met, if the cell service quality is reduced and key KPI indexes are deteriorated, automatic optimization processing can be carried out, and the influence of the overlapping coverage adjacent cell on co-frequency interference of the serving cell is reduced.
