Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiments provide a kind of method assessing the interference of Physical Cell Identifier PCI mould three, as shown in Figure 1, comprising:
101, the sampled data of the multiple sampled point in Serving cell is obtained.
Wherein, the sampled data of each sampled point comprises the PCI of each neighbor cell and the RSRP (Reference Signal Receiving Power, Reference Signal Received Power) of each neighbor cell.
It should be noted that, the RSRP of community is for weighing the signal strength signal intensity of community, and wherein the unit of RSRP is dBm (dBm).
Concrete, sample in different location within the specific limits, the initial data of each sampled point is PCI and RSRP of all communities that can receive in the sampling position of this sampled point, comprising PCI and RSRP of Serving cell.
Preferably, in the sampled data of each sampled point, all neighbor cells are according to the RSRP descending of community.
Exemplary, following table is the data that a sampled point gathers.Neighbor cell is according to the descending of RSRP.
It should be noted that, the embodiment of the present invention only analyzes PCI mould three interference of neighbor cell to this Serving cell of a Serving cell.If in the data gathered, Serving cell is different, so can according to the packet of Serving cell by all collections, the Serving cell often organizing data is identical, then processes according to the method grouping described in the embodiment of the present invention.
102, from the optional community of each sampled point, PCI mould three is worth and is worth with Serving cell PCI mould three mould three interfered cell that equal community is defined as each sampled point.
Wherein, optional community is the neighbor cell that top n RSRP that in the neighbor cell of sampled point, RSRP arranges from big to small is corresponding; N is for presetting positive integer.
It should be noted that, optional community is the community that in all neighbor cells of each sampled point, RSRP is larger, the neighbor cell that namely signal strength signal intensity is larger.
It should be noted that, the neighbor cell effect of signals to Serving cell large due to signal strength signal intensity is large, the very weak impact of neighbor cell on Serving cell of signal strength signal intensity is negligible, so for the ease of operation with calculate, the present embodiment mainly considers that neighbor cell that signal strength signal intensity is large is to the signal disturbing of Serving cell.Further, the all embodiments of the present invention are all in order to quantitative evaluation neighbor cell is to PCI mould three interference of Serving cell, only have PCI mould three value of neighbor cell and the PCI mould three of Serving cell to be worth and identically just can cause PCI mould three interference to Serving cell, so need to calculate, signal strength signal intensity is large and PCI mould three value is worth equal neighbor cell with Serving cell PCI mould three.
It should be noted that, the occurrence of N can rule of thumb set, and such as, N is set to 3.The number of mould three interfered cell of each sampled point is 0-N.
Concrete, for each sampled point, top n community larger for RSRP in neighbor cell is defined as optional community, then PCI mould three value of each community in optional community is calculated, and compare with PCI mould three value of Serving cell, if both are identical, then this neighbor cell is defined as mould three interfered cell of this sampled point.
Exemplary, above table is example, and N=3.By front 3 neighbor cells larger for RSRP in sampled data, the i.e. community of PCI=355, the community of PCI=164 and the community of PCI=221, be defined as optional community, then calculation services community PCI mould three value is 407mod3=2, PCI mould three value calculating each community in optional community is respectively 355mod3=1, 164mod3=2, 221mod3=2, can determine that being worth identical community with the PCI mould three of Serving cell is the community of PCI=164 and the community of PCI=221, so the community of PCI=164 and the community of PCI=221 are defined as mould three interfered cell of this sampled point.
103, mould three interference level of each sampled point is determined according to the RSRP of the RSRP of Serving cell and mould three interfered cell of each sampled point.
Concrete, the realization of step 103 can be mould three interference level difference of the RSRP mean value of mould three interfered cell of the RSRP of Serving cell and each sampled point being defined as each sampled point.
It should be noted that, there is PCI mould three interference each mould three interfered cell to Serving cell, and the degree that PCI mould three disturbs is different, in order to PCI mould three annoyance level suffered by quantitative evaluation Serving cell, so calculate the RSRP mean value of all mould three interfered cells, assess PCI mould three interference of mould three interfered cell to Serving cell with this mean value.
It should be noted that, the signal strength signal intensity of mould three interfered cell is larger, so disturbs stronger to the PCI mould three of Serving cell.Namely the RSRP of mould three interfered cell is larger, and the RSRP mean value of mould three interfered cell is larger, and so the value of mould three interference level is less.
It should be noted that, majority of case, terminal is connected in the maximum community of signal strength signal intensity, and the community that namely RSRP is maximum is Serving cell.But in some cases, such as record the neighbor cell stronger than the serving cell signal intensity of current access, but when also not switching to new community, the value of the RSRP of neighbor cell is larger than the value of the RSRP of Serving cell, so the RSRP that may there is the Serving cell of sampled point is less than the RSRP mean value of mould three interfered cell, namely mould three interference level is the situation of negative value.
Concrete, for each sampled point, calculate the RSRP mean value of mould three interfered cell, then calculate the difference of the RSRP of this mean value and Serving cell, and this difference is defined as mould three interference level of this sampled point.
Exemplary, the data of sampled point as shown above, have determined that the community of PCI=164 and the community of PCI=221 are mould three interfered cell of this sampled point in a step 102.The RSRP mean value calculating the community of PCI=164 and the community of PCI=221 is
and then the difference of the RSRP calculating this value and Serving cell is (-95)-(-104.4)=9.4dB, i.e. the mould three interference level 9.4dB of this sampled point.
It should be noted that, for the sampled point not having mould three interfered cell, mould three interference level of this sampled point can not be calculated.Also can mould three interference level of this sampled point be set to just infinite.The present invention does not limit this.
For the sampled point not having mould three interfered cell, illustrate in the sampled data of this sampled point, PCI mould three is there is not and to disturb or PCI mould three disturbs less in neighbor cell to Serving cell, can ignore, this sampled point direct can be put under the scope of the sampled point not having PCI mould three to disturb, so also step 104 can not be performed for these sampled points.
It should be noted that, above provide mould three interference level obtaining sampled point according to the RSRP mean value of mould three interfered cell of each sampled point and the difference of the RSRP value of Serving cell, but the realization of step 103 is not limited to said method, it can also be the additive method by mould three interference level obtaining quantizing in conjunction with the RSRP of neighbor cell and the RSRP of Serving cell, such as using the RSRP mean value of mould three interfered cell of each sampled point and the ratio of the RSRP of Serving cell as mould three interference level, the present invention does not limit this.
104, mould three level of interference of each sampled point is determined according to mould three interference level of each sampled point and reference level thresholding.
Wherein, set of real numbers is divided at least two intervals by reference level thresholding; Each interval corresponding mould three level of interference.
It should be noted that, each sampled point calculates mould three interference level, or each has the sampled point of mould three interfered cell to calculate mould three interference level.For Serving cell, corresponding multiple mould three interference level of multiple sampled point, the value of mould three interference level is incomplete same, so disturb in order to the PCI mould three of quantitative evaluation neighbor cell to Serving cell, need mould three interference level divided rank, quantize PCI mould three by the division of grade and disturb.
It should be noted that, when the difference of the RSRP mean value of mould three interfered cell by the RSRP of Serving cell and each sampled point is defined as mould three interference level of each sampled point, the value of mould three interference level is less, illustrate that the signal strength signal intensity of mould three interfered cell is larger relative to the signal strength signal intensity of Serving cell, disturb larger to the PCI mould three of Serving cell.So when mould three interference level is negative value, the PCI mould three of mould three interfered cell to Serving cell disturbs very large.When using the RSRP mean value of mould three interfered cell of each sampled point and the ratio of the RSRP of Serving cell as mould three interference level, the value of mould three interference level is less, illustrate that the signal strength signal intensity of mould three interfered cell is larger relative to the signal strength signal intensity of Serving cell, disturb larger to the PCI mould three of Serving cell, when mould three interference level is for being less than 1, the PCI mould three of mould three interfered cell to Serving cell disturbs very large.
It should be noted that, reference level thresholding can only have one, also can have multiple.Reference level thresholding just set of real numbers is divided into an interval more than the value of reference level thresholding, each interval corresponding mould three level of interference, thus mould three interference level corresponding for each sampled point is quantified as different brackets.
Concrete, determine that mould three interference level of each sampled point is interval at which, and the grade that this interval is corresponding is defined as mould three level of interference of this sampled point.
Further, reference level thresholding comprises: at least one reference level thresholding; In at least one reference level thresholding, the value of each reference level thresholding is different.
Concrete step 104 can be refined as following two steps:
The first step: according to mould three interference level of each sampled point and the magnitude relationship of at least one reference level thresholding, determines that mould three interference level of each sampled point is affiliated interval.
Second step: interval belonging to mould three interference level of the corresponding relation between interval and mould three level of interference and each sampled point, determines mould three level of interference of each sampled point.
Exemplary, when the difference of the RSRP mean value of mould three interfered cell by the RSRP of Serving cell and each sampled point is defined as mould three interference level of each sampled point, reference level thresholding is set and is respectively-6dB and 6dB, this reference level thresholding set of real numbers is divided into three intervals (-∞ ,-6], (-6,6), [6 ,+∞), three interval corresponding severe jammings respectively, general interference and weak jamming Three Estates.More than table is example, step 103 has determined that mould three interference level of this sampled point is 9.4dB, according to the magnitude relationship between mould three interference level and reference level, can determine that mould three interference level of this sampled point drops on interval [6, + ∞) on, according to interval [6 ,+∞) and weak jamming between corresponding relation, determine that mould three level of interference of this sampled point is weak jamming.
105, the number of the sampled point of identical molds three level of interference and the ratio of total sampled point number is determined.
It should be noted that to only have to be carried out by sampled point identical for Serving cell analyzing and could analyze PCI mould three interference of neighbor cell to this Serving cell.The Serving cell of the sampled data of the sampled point in all embodiments of the present invention is identical.So can be sorted out by sampled point according to the difference of Serving cell, but directly perform step 105.
It should be noted that, because the sum of the sampled point of different service cells is different, the Serving cell that the Serving cell relative sample point that sampled point is many is few is just many in the number of the sampled point of each grade.So PCI mould three annoyance level of this Serving cell can not be judged from the sampled point number of each grade, PCI mould three annoyance level of neighbor cell to Serving cell can be assessed from the ratio of the sampled point of each grade.
Concrete, determine the number of the sampled point that each sampling grade is corresponding, and the sampled point number calculating each grade accounts for the ratio of total sampled point number, just can draw PCI mould three probability of interference of different brackets.
106, quantized value is disturbed according to the mould three of ratio acquisition Serving cell.
It should be noted that, the mould three of Serving cell disturbs quantized value to be exactly the mould three of neighbor cell to Serving cell is being disturbed to the value weighing use in degree.
Concrete, at least can there are following two kinds of modes in the realization of step 106:
The first: disturb ratio corresponding to the strongest grade to disturb quantized value as the mould three of described Serving cell mould three in described ratio.
It should be noted that, total determine that the number of the sampled point of identical molds three level of interference and the ratio of sampled point number are exactly the ratio determining that each grade is corresponding.Necessarily there is the corresponding mould three of a grade to disturb the strongest grade in all grades, being disturbed by mould three ratio corresponding to the strongest grade when disturbing quantized value as the mould three weighing mould three annoyance level that Serving cell is subject to.Now, mould three disturbs quantized value larger, and the mould three that the Serving cell illustrated is subject to disturbs larger.
The second: using the weighted value of each ratio and mould three as described Serving cell disturb quantized value.
It should be noted that, first method determines that the mould three of Serving cell disturbs a kind of method for simplifying of quantized value.If the ratio that two Serving cell moulds three disturb the strongest grade corresponding is identical, when but the ratio of other grades is different, there is difference in mould three annoyance level that two Serving cells are subject to respectively, but the mould three that two Serving cells are determined according to first method disturbs quantized value identical.So optimize, mould three that is after the ratio of each grade can being multiplied by point other weight coefficient and that be defined as Serving cell disturbs quantized value.Generally, show that the value of the weight coefficient that mould three disturbs stronger grade corresponding is larger.The weight coefficient of the such as ratio that severe jamming grade is corresponding is 0.8, and the weight coefficient of the ratio that general level of interference is corresponding is 0.6, and the weight coefficient of the ratio that some grades of disturbing are corresponding is 0.2.Now, mould three disturbs quantized value larger, and the mould three that the Serving cell illustrated is subject to disturbs larger.
Exemplary, if ratio corresponding to the severe jamming grade of the first community is 20%, ratio corresponding to general level of interference is 10%, and ratio corresponding to weak jamming grade is 40%; The ratio that the severe jamming grade of the second community is corresponding is 20%, and ratio corresponding to general level of interference is 40%, and ratio corresponding to weak jamming grade is 10%.The mould three of the first community so got according to first method disturbs quantized value to disturb quantized value identical with the mould three of the second community, is all 0.2.Be 0.8 at the weight coefficient of ratio corresponding to severe jamming grade, the weight coefficient of the ratio that general level of interference is corresponding is 0.6, when the weight coefficient of the ratio that some grades of disturbing are corresponding is 0.2, the mould three of the first community disturbs quantized value to equal 0.8*0.2+0.6*0.1+0.2*0.4=0.30, and the mould three of the second community disturbs quantized value to equal 0.8*0.2+0.6*0.4+0.2*0.1=0.43.
