Description
Technical field
The present invention relates to field of communication technology, in particular to a kind of shared site appraisal procedure and system.
Background technique
Shared infrastructure site is the common measures taken for pushing mobile network generally to cover on international market.Currently, Chinese
The 4G network that steel tower is just accepting big operator, China three with all strength creates demand, and deepens and promote Joint construction and sharing work, reduces movement
The construction cost of the communications infrastructure.In the process of construction of site, the existing huge storage station of the preferential renovation and utilization of steel tower company
Location resource, what can be shared is no longer newly-built, and site shares rate and commonly reaches 70% or more.It can be seen that shared integration is as station
How an important means in the planning construction of location quickly generates site according to practical now net scene and recommends, in shared planning
Become more more and more urgent.
After site program results generate, most of demand site, the storage candidate site for having it that can reuse is only less
Partial demand site needs to create on former address.And at the storage site that can be reused, traditional shared addressing mode
Generally by the priority importance of program results, the important evaluation that is used as site to reuse from big to small according to priority arrangement
One of, evaluative dimension Primary Reference network topology, emulation covering, the combined factors such as site importance degree consider.Meanwhile In
Before practical construction, it is still necessary to site inspection, but be substantially based on above-mentioned prediction case still according to the factor of emulation of coverage capability, push away
Send emulation, the preferable site of station spacing reuses site as candidate.
But in fact, whether candidate site is used as the target that reuses of demand site, should mainly pay close attention in real network,
Practical covering and interference effect of the candidate site signal quality around demand site.It more can reflect multiple candidate sites in this way
Practical coverage condition within the scope of demand site.According to above-mentioned measured signal quality, the priority of candidate site is determined.Tradition
Sharing mode under, candidate site determines whether that the reference to be reused depends on planning, and it is artificial to reconnoitre middle foundation at the scene
It is empirically determined under conditions of multiple candidate sites, be preferentially applied to actual site according to program results and reuse in scheme.But
Traditional planning does not consider the quality of real network signal, that is, multiple candidate sites of plane-generating, candidate in selection
When site is as practical application, network actual signal effect is not considered, but the final goal primary concern of practical application is now netted
Therefore signal quality situation reasonably surveys assessment site based on network and reuses the method for priority there is an urgent need to a kind of, so that
The scheme that reuses more meets the practical coverage condition of network.
Therefore, there is an urgent need in the art to develop a kind of more to meet the shared site appraisal procedure of network authenticity and be
System.

Specifically, doing detailed statement below by citing.
Generation demand site center, fringe region counterclockwise and are selected surrounding and needed centered on demand site
Site is asked to take it apart from upper one if search site number is less than M (5≤M≤10) apart from the nearest identical site of standard
A circle is searched for centered on it in the nearest site in center counterclockwise, selects apart from the nearest identical site of standard,
One circle search finishes, if not meeting search number requirement, continues next round search, until searching qualified site.
With this M site, Thiessen polygon is generated, average station spacing D is calculated, it can thus be concluded that demand site is in this area
Average site covering radius is R=D/2, using this radius as the basic covering radius in demand site.So at this point, central area is station
Within the scope of point position 0 to 0.8R, fringe region is in 0.8R to 1.2R range.
Qualified network testing data is extracted, due to assessing other candidate cells near with demand site in the area
The signal quality in domain is considered, then acquisition radius is 1.2R's centered on its signal testing pickup area is demand site
Range areas.
In addition, need in the grid of each test includes all candidate site wireless test signal numbers to be assessed simultaneously
According to.Cell phone application, if receiving all candidate sites signal to be assessed simultaneously a position, acquires in test scope
Above-mentioned signal, and be reported to cloud.
The data that the present invention measures are to have latitude and longitude information, can be by analyzing its test data is which belongs to
Region, then take its corresponding measured value.I.e. test point falls on central area, takes its SINR, and test point falls on edge, takes reception function
Rate index.
It assesses candidate site and acquires signal quality in demand region, carry out center and peripheral regional signal mass ratio pair.Tool
Body, by taking the central area of demand site as an example, setting some BIN lattice points, to be respectively received the signal from all candidate sites strong
Degree.Score value according to candidate site number, after generating sequence.Such as candidate site number is M, then score value is 1... (2M-
1) signal strength, received according to all candidate sites of signal BIN lattice point in current location, according to sorting from large to small, according to
Secondary to assign corresponding score value according to ranking results are corresponding, signal strength is bigger, and score value is bigger, i.e., sequentially gives point from big to small
Value.Such as signal strength maximum place candidate site score value is (2M-1) point.If not containing some candidate site letter in BIN lattice
Number, illustrate that this candidate site covering power of current location is insufficient, do not cover demand region, then the candidate site score value is most
It is low.The finally all score values in each candidate site in superposition central area.
Similarly, in central area assessment signal quality SINR, the collected all BIN lattice of domain test are obtained, it is relatively more every
The SINR of a BIN lattice candidate site in the position carries out SINR from big to small on each BIN lattice according to candidate site number
Sequence, it is assumed that M candidate site, according to above-mentioned ranking results, successively 1, SINR the smallest candidate stations of imparting score value (2M-1) ...
Location is 1 in the score value, if the BIN lattice point does not collect the SINR of some candidate site, score value is 0 point.Finally, superposition is every
All SINR score values in a candidate site.
Finally, comprehensive assessment covers and interferes quality in demand region.To each candidate site, aforementioned covering score value is generated
With interference score value, and the two score value is superimposed, as the net assessment score value of the candidate site.It sorts according to total score size,
The wherein maximum candidate site of score value, covering and interference are best in the quality of demand region, preferentially based on the site as excellent
Select the recommendation that reuses.
The above-mentioned explanation for existing net test data, can spread over the drive test data of wireless network, have location information
MR correction data, or the set covering theory with existing net signal characteristic, interference matrix.Further, it is still applied to based on existing
Net test data is modified simulation matrix, and what is generated after processing has the correction matrix of existing net signal characteristic.
It, can according to the technique and scheme of the present invention and its invention in addition, it should also be understood that, for those of ordinary skills
Design is subject to equivalent substitution or change, and all these changes or replacement all should belong to the protection of appended claims of the invention
Range.
