Afterwards, the singal reporting code of existing TD-SCDMA network system is calculated.Wherein, there is TD-SCDMA to existing based on above-mentioned
The analysis of each sampled point of network system, counts the network overlapped coverage coefficient of existing TD-SCDMA network system, network and does
Disturb strength factor and network high interference coefficient.
Specifically, the embodiment of the present invention can be determined as follows the singal reporting code of first network system.
First, network overlapped coverage coefficient is：Overlap coverage cell number>Overlap coverage cell number threshold value and adjacent area is disturbed
Intensity>The sampled point accounting of adjacent area interference strength threshold value.
Wherein, overlapping coverage cell number threshold value is used to judge to overlap whether coverage cell number reaches standard value, overlaps covering
Cell number threshold value is defaulted as 3；That is, above-mentioned network overlapped coverage coefficient is used for the institute that will be unsatisfactory for overlapping coverage rate requirement
There are TD-SCDMA cells to list；Above-mentioned adjacent area interference strength threshold value is used to judge whether adjacent area interference strength reaches standard value, adjacent
Area's interference strength threshold value default value is 30.
Secondly, network interferences strength factor is：Overlap coverage cell number<Overlap coverage cell number threshold value and adjacent area is disturbed
Intensity>The sampled point accounting of adjacent area interference strength threshold value.
Wherein, network interferences strength factor be single subdistrict as adjacent area give other area interference contribution degree sums.
Then, network high interference coefficient is equivalent SINR<The sampling number of high interference threshold value/total sampling number.Wherein ,/
It is division arithmetic.
Wherein, high interference threshold definitions are equivalent SINR thresholdings, are defaulted as 6dB.
That is, network interferences strength factor further deletes the TD-SCDMA cells listed by above-mentioned steps
Choosing, excludes interference strength cell high.
So, above-mentioned network high interference coefficient is for for excluding remaining the whole network TD- after high interference intensity cell
Whether SCDMA cells, calculating network high interference coefficient meets requirement, will be up to standard after TD-SCDMA cells as co-sited upgrading build
If TD-LTE cell candidates.
In embodiments of the present invention, the drive test data of the network system after simulation upgrading and the process of singal reporting code can be as
Under：

The drive test data for stating first network system enters line displacement, obtains the simulation drive test data in second network system, wherein, the
Two network systems (can be in embodiments of the present invention TDD-LTE network system for the upgrade of network system of first network system
System), it is necessary to explanation, the TDD-LTE base stations in the embodiment of the present invention can be with the co-located construction of TD-SCDMA base station.Specifically
, RSRP (Reference Signal Receiving Power, Reference Signal Received Power)=the of the second network system
The RSCP-TDS simulation TDL offsets of one network system, wherein, TDS simulation TDL offsets are TD-SCDMA simulations TD-LTE
Offset is that the RSCP of TD-SCDMA cells (Time Division Switching, time switching) is converted into TD-LTE is small
The difference of the RSRP in area, TD-SCDMA simulation TD-LTE offsets are defaulted as 18dB.
Then, the analogue communication index of the second network system is determined according to above-mentioned simulation drive test data.
When implementing, the Your Majesty of the Serving cell that the embodiment of the present invention can be first according to where the analog sampling point

Difference between the simulation PCCPCH RSCP and the simulation PCCPCH RSCP of each neighbor cell of cell of being engaged in, and difference is more than
The total number of the neighbor cell of default adjacent area interference threshold overlaps coverage cell number as simulation；Then, by weighted statistical
Computing, obtains and is in the neighbor cell of frequency with the Serving cell where the analog sampling point, small according to the homogeneous frequency adjacent
The simulation PCCPCH RSCP in area, calculate each neighbor cell to the simulation adjacent area interference strength produced by the Serving cell.
Further, judge whether each analog sampling point meets condition：The simulation of the analog sampling point overlaps coverage cell
Number is more than the 4th predetermined threshold value, while the simulation adjacent area interference strength of the analog sampling point is more than the 5th predetermined threshold value；And will

And number and the analog sampling point total number of the analog sampling point of above-mentioned condition will be met carry out division arithmetic, operation result is made
It is the analog network high interference coefficient of second network system.
Specifically, based on the TDD-LTE RSRP sampled points for simulating, calculate the weak coverage coefficients of LTE, without coverage coefficient, cover
The indexs such as lid rate.
For example, the weak coverage coefficients of LTE are the number of sampled points of the RSRP less than -110dBm divided by the individual of total sampled point
Number；Number of the number of sampled points of the LTE without coverage coefficient for RSRP less than -120dBm divided by total sampled point；LTE coverage rates are
Number of the number of sampled points of the RSRP higher than -100dBm divided by total sampled point.
These parameters are used to determine whether the LTE cells of the co-sited upgrading determined in above-mentioned steps meet continuous covering and refer to
Mark, meets final output TD-LTE co-sited upgrading cell list, the alternative networking planning simulation addressing of the program after index
Deng work, and reliability and accuracy are higher.
