Background technology
At present, in order to carry out the flux and flow direction analysis of toll telephone, key is that called number is carried out trunk code to be split.In traditional area code method for splitting, at first to set up a trunk code table, this table comprises all regions name, corresponding trunk code, and other relevant informations.When called number being carried out area code when splitting,, each called number is all needed to inquire about whole area code table, to find its corresponding area code because the digit length scale of each trunk code differs from the customer call ticket.Some improved method is at first trunk code to be sorted, and adopts interval dichotomy to quicken matching process when coupling.But because the ticket quantity of telecommunications toll telephone is very huge, the number of comparisons that each fractionation needs is still many, and treatment effeciency is still not high.
Can find from traditional area code method for splitting, a large amount of processing times is to spend in to judge whether called number is on the legal trunk code, can consider if can set up a kind of mapping relations of trunk code, make as long as by relatively simple, just can judge fast from called number which combination is effective trunk code, which combination is not effective trunk code, can improve Business Processing efficient effectively undoubtedly.
The bitmap reflection method is a mutation of reflection method, and its output has only 0 and 1 two value.By the mapping of logical definition input value and output valve, can classify to input value fast.For example defining 1 is effective mapping, the 0th, and invalid mapping just can be distinguished the input value of effective mapping and invalid mapping easily.
Summary of the invention
The method that the purpose of this invention is to provide a kind of efficient fractionation toll telephone area code just provides a kind of method of utilizing the bitmap reflection method that the toll telephone area code is split.Use this method can improve data-handling efficiency greatly, can from the called number the customer call ticket, split out trunk code fast, for the analysis of long-distance call flux and flow direction and charging provide real time data.
The object of the present invention is achieved like this: a kind of method of efficient fractionation toll telephone area code is characterized in that: use the bitmap reflection method to split the toll telephone area code, to determine the long-distance call flow and the flow direction.

Embodiment
The present invention is a kind of method of using the bitmap reflection method efficiently to split the toll telephone area code, to determine the long-distance call flow and the flow direction.This method mainly comprises two steps:
A, domestic, external two the multidimensional toll telephone area code bitmap mapping tables of structure;
B, determine mapping ruler, and carry out the toll telephone area code according to domestic, external two area code bitmap mapping tables and split.
At first to the feature of toll telephone area code sign indicating number, just input value is analyzed and researched in the present invention.Find that all long-distance call position numbers all are made up of digital 0-9.Wherein the area code first place of National calls is 0, and inferior position is not 0; First two of the area code of international (containing the Hong Kong, Macao and Taiwan) toll telephone is 00.And though the figure place of each long-distance call area code is unfixing, its figure place is not oversize.Domestic long-distance call area code figure place is between 3～5, for example: Beijing is 010, and Cuona County, Yunnan is 08030.International long distance call area code figure place is between 4～6, for example: Japan is 0081, and the section kos is 00619162.
The basic principle that the present invention uses the bitmap reflection method to split trunk zone item sign indicating number is: for each trunk code, and character string informations of forming by several numerals all, shape such as R
1R
2R
3Rm in order to set up mapping relations, can represent this long-distance call area code with the m-dimensional space mode, and the dimension combination that meets domestic or international long distance call area code character string information feature is provided with a mark respectively, and the dimension combination of not doing sign is not legal area code just.So only need to check whether the dimension combination that splits character string from called number is an effective marker, just can finish the fractionation of long-distance call position number.Consider that domestic area code is different with international area code length, in order to reduce the judgement number of times, the present invention makes up domestic, external two upright two area code bitmap mapping tables are respectively applied for the fractionation of domestic long-distance call area code and international long distance call area code.Determine mapping ruler then, and carry out the fractionation of toll telephone area code according to domestic, external two area code bitmap mapping tables.
