Step 1, judge whether include " iPhone " in the UA field:, otherwise get into step 2 if then mb_str is iPhone;
Step 2, judge whether include character "/" in the UA field: if the part of then getting this character "/" front in the UA field is as mb_str, otherwise whole UA field is as mb_str: after execution in step 2, get into step 3;
Step 3, judge whether mb_str comprises " Mozilla ":, then get into step 4 if do not comprise " Mozilla "; If comprise " Mozilla ", then further judge:
If 3a) the UA field comprises " Nokia ", then mbstr is modified in the UA field " Nokia " and begins till first character "/"
If 3b) the UA field comprises " HTC ", then mb_str is modified in the UA field " HTC " and begins till first "/", " " or ") "
If 3c) the UA field comprises " MOT ", then mb_str is modified in the UA field " MOT " and begins till first "/"
If 3d) the UA field comprises " Xda ", then with mb_str be modified in the UA field " Xda " begin to first character "; " or "/" till, if do not have after " Xda " field "; " and "/", then mb_str is modified to " Xda " and begins the field till the last character.
If 3e) the UA field comprises " samsung/ ", then mb_str is modified in the UA field " samsung/ " and begins to " samsung/ " afterwards till first "/"
If 3f) the UA field comprises " samsung " but does not comprise " samsung/ ", till then mb_str being modified to " samsung " in the UA field and beginning first "/" after " samsung " field
If 3g) the UA field comprises " LG ", then mb_str is modified in the UA field " LG " and begins till " LG " first "/" afterwards
If 3h) the UA field comprises " hp ", then mb_str is modified in the UA field begin first "/" or ") afterwards from " hp " to " hp " " till, if do not have "/" and ") after " hp " field ", then get last character always.
If 3i) the UA field comprises " LG ", till then mb_str being modified to " LG " in the UA field and beginning first "/" after " LG " field
If 3j) the UA field comprises " ASUS ", then mb_str is modified in the UA field " ASUS " and begins till " ASUS " first "/" afterwards
If 3k) the UA field comprises " GIGA ", then mb_str is modified to that " GIGA " begins to a last character in the UA field
31), then mb_str is modified to that " dopod " begins "/", ") afterwards to " dopod " in the UA field if the UA field comprises " dopod " " or "; " till;
Step 4, when not comprising " Mozilla ", further judge at mb_str:
4a), for mb_str be " MOT " beginning, if mb_str comprise "; ", then mb_str is modified to and removes "; " and subsequent part;
4) b, be " TIANYU-KTOUCH " beginning for mb_str, just mb_str is modified to " TIANYU-KTOUCH " in the UA field and begins till second "/" after " TIANYU-KTOUCH ";
4c), be " Samsung " beginning for mb_str, just mb_str is modified to " Samsung " in the UA field and begins till second "/" after " Samsung ";
4d), for mb_str be " Sharp " beginning, just mb_str is modified to the part till from " Sharp " to "/SHC " in the UA field;
Be that " UNTRUSTED " starts 4e), for mb_str; If the UA field comprises " Nokia ", " SonyEricsson ", " LG ", " MOT ", " Amoi " or " Panasonic " field, just mb_str is modified to the part till above-mentioned field begins first "/" after the above-mentioned field;
4f), be " Vodafone ":, then mb_str is modified to " Toshiba " and begins till " Toshiba " first "/" afterwards if the UA field comprises " Toshiba " for mb_str; Otherwise, mb_str is modified to the UA field begins the part till second "/"
4g), for mb_str with " samsung " or " kejian " beginning, if the UA field comprises " * ", then mb_str is modified to from " samsung " or " kejian " and begins previous character to " * ".
Four, count the number of users (group by UA) of each effective terminal models.
Five, preserve number of users greater than 10 effective terminal models, other deletions.
Six, form second mapping table between ID (like MSISDN) and the terminal models according to effective terminal models, can also comprise parameters such as UA field in this table, a kind of form of this table is as shown in the table:
Seven, based on the first above-mentioned mapping table and second mapping table; MSISDN with the user is an index; Association count same user IMEI, UA field and, information such as terminal models; And extract first eight bits among the IMEI as TAC, thus form the 3rd mapping table between MSISDN, unit type approval code TAC and the terminal models of 3 months granularities, can be recorded into following form:
Eight, based on above-mentioned the 3rd mapping table; To each TAC; Count the distributed number ratio of each corresponding terminal models of this TAC; Choose (maximum 7) terminal models data of the highest predetermined quantity of proportional numerical value, be recorded in the TAC-terminal models mapping table, this ratio is as the confidence level of TAC corresponding to terminal models.For example:
Through statistics; Find that TAC number (preceding 8 of IMEI) is 86011100 pairs 2 kinds of possible terminal models should be arranged; Comprise the cruel TD-6168H of group and extremely send TD-6168; The former the record number in the 3rd mapping table account for this TAC correspondence the total number of records 70%; Promptly this TAC confidence level of " extremely sending TD-6168H " corresponding to terminal models is 70%, the record number of the latter in the 3rd mapping table account for this TAC correspondence the total number of records 28%, promptly this TAC confidence level of " extremely sending TD-6168 " corresponding to terminal models is 28%.A kind of corresponding relation of TAC that obtains thus and terminal models is as shown in the table:
| TAC | Brand 1 | Model 1 | Confidence level 1 | Brand 2 | Model 2 | Confidence level 2 |
| 86011100 | Cruel group | TD-6168H | 70％ | Cruel group | TD-6168 | 28％ |
Nine, every interval setting cycle as 3 months, repeats above-mentioned steps, and statistics obtaining TAC in the predetermined amount of time corresponding to the confidence level parameter of terminal models.Can the confidence level parameter that obtain in adjacent two cycles be merged in such a way:
To each TAC, the statistics in adjacent two predetermined amount of time,, select the confidence level parameter of predetermined quantity respectively according to confidence level parameter order from big to small;
Then; In the confidence level parameter of selecting; Calculate all corresponding terminal models of this TAC up-to-date confidence level parameter and value; And the up-to-date confidence level parameter of calculating each corresponding terminal models of this TAC and said and ratio value, according to this ratio, revise the confidence level parameter of each terminal models of this TAC correspondence.
Above-mentioned merging mode specifically can realize according to following steps:
1) statistics obtains TAC and the mapping table of terminal models confidence level parameter in adjacent two cycles; Here; The mapping table in previous cycle in adjacent two cycles is called old table, with in adjacent two cycles the back one-period mapping table be called new table:
2) duplicate a primary data to old table as mapping table after merging.
3) in new table, extract a line item (comprising TAC number, terminal models, confidence level):
If these TAC data are not included in the old table, then directly this record is increased in the mapping table after the merging;
If the TAC data are included in the old relation table; In new, the old relation table all terminal models, confidence level that should TAC number being extracted; Sort according to confidence level; From new, old table, choose the highest predetermined quantity of confidence level (for example seven s') terminal models, the ratio of the up-to-date confidence level parameter of calculating each terminal models and the up-to-date confidence level parameter sum of all terminal models of choosing is modified to this ratio with the confidence level parameter of this each terminal models.
Because same TAC maybe be corresponding to the mass of terminals model; Merge through several bigger terminal models of quantitative proportion in the new and old table being carried out weighting with upper type; And revise the confidence level parameter of TAC corresponding to each terminal models, output more is worth the data of care.And, then can not consider for the littler terminal models of quantity once.A kind of example that merges according to aforesaid way is following, only considers 2 the highest terminal models of confidence level parameter in new, the old table in this example:
Suppose that the confidence level parameter of TAC=8601100 and each terminal models is as shown in the table in the mapping table in last cycle in adjacent two cycles:
| TAC | Brand 1 | Model 1 | Confidence level 1 | Brand 2 | Model 2 | Confidence level 2 |
| 86011100 | Cruel group | TD-6168H | 70％ | Cruel group | TD-6168 | 28％ |
In the mapping table of one-period, the confidence level parameter of TAC=8601100 and each terminal models is as shown in the table after supposing in adjacent two cycles:
| TAC | Brand 1 | Model 1 | Confidence level 1 | Brand 2 | Model 2 | Confidence level 2 |
| 86011100 | Cruel group | TD-6168H | 80％ | Cruel group | TD-6268 | 10％ |
In above-mentioned two tables, the TAC of " 86011100 " is 80% corresponding to the up-to-date confidence level parameter of TD-6168H, is 28% corresponding to the up-to-date confidence level parameter of TD-6168, is 10% corresponding to the up-to-date confidence level parameter of TD-6268, so the confidence level weighting algorithm:
TD-6168H confidence level: 80%/(80%+28%+10%)=68%
TD-6168 confidence level: 28%/(80%+28%+10%)=24%
TD-6268 confidence level: 10%/(80%+28%+10%)=8%
After the merging, TAC=8601100 is as shown in the table corresponding to the confidence level parameter of following terminal models:
| TAC | Brand 1 | Model 1 | Confidence level 1 |
| 86011100 | Cruel group | TD-6168H | 68％ |
| 86011100 | Cruel group | TD-6168 | 24％ |
| 86011100 | Cruel group | TD-6268 | 8％ |
