Rule according to the setting of mobile radio communication network users number, each mobile subscriber number can be split as mobile network number, local network number, three attribute fields of client's number, when tissue database and searching database, can locate convenient the modification and accessing database fast.
Each mobile subscriber number also has a tracking depths attribute field, is used for realizing in monitoring system the function of intelligent-tracking.Will be in conjunction with its effect in the monitoring analysis process of the illustrative communication process explanation of Figure 16.
Figure 16 is that intelligence is found to illustrate with the communication process of tracking target in the monitoring system.
If setting mobile subscriber A in monitoring system is monitoring objective, and supposes that its tracking depths attribute field is 3.
In communication process, mobile subscriber A sends SMS message to mobile subscriber B, and monitoring system can also join mobile subscriber B in the monitoring objective according to the intelligent algorithm of number filtering of introducing below and tracking, and it is 2 that its tracking depths attribute field is set automatically; In another time communication process, mobile subscriber C sends SMS message to mobile subscriber B, and system discovery also joins mobile subscriber C in the monitoring objective, and the tracking depths attribute field is made as 1; Mobile subscriber C sends SMS message to mobile subscriber D, and system discovery also joins mobile subscriber D in the monitoring objective, and the tracking depths attribute field is made as 0.In mobile subscriber E sent SMS message process to mobile subscriber D, the tracking attribute field of system discovery mobile subscriber D was made as 0, mobile subscriber E is not joined in the monitoring objective.
So far, monitoring system can have been monitored the mobile subscriber B that has direct relation with mobile subscriber A; And from motion tracking mobile subscriber C, the D that may be correlated with, got rid of the less mobile subscriber E of correlation.By limiting monitoring range effectively, obtain Useful Information.
Figure 17 is a kind of filtration and a tracking intelligent algorithm based on number in the monitoring system, is used to search for message calling number and called number and whether belongs to monitoring objective; And, can have the function of intelligence discovery and tracking target according to the setting of system.Its algorithm flow is as follows:

Figure 18 is a kind of keyword Matching Algorithm in the monitoring system, be used for searching for current content of short message and whether have some sensitive content, its algorithm thought is: the predefined one group of responsive word be concerned about of system user, constitute the set of keywords in the algorithm, when monitoring, short message data to all users carries out traversal search, if detect and have keyword in the short message, think that then the active user meets the monitoring condition, then write down the short message communication process, and the active user is added in the monitoring tabulation.
Before introducing the keyword matching algorithm, be defined as follows notion and computing:
Unit length: the long measure of short message data content, determine by the coded system of short message.Such as in the English short message, being 7 bits, in Chinese short message 2 bytes.
Current data: the unit length short message data that data pointer is pointed.
Set of keywords: a set of keyword, minimum length are a unit length.
Keyword subset is closed: to set of keywords after treatment, and the one group of new key that obtains.
Data belong to set of keywords: the data of first unit length of the keyword of the part in current data and the current set of keywords are identical.
Data are mated with keyword: the data of first unit length of current data and keyword are identical.
Data and keyword mate fully: data and keyword coupling, and this keyword is a unit length.
Algorithm flow is as follows:
1) initialization data pointer points to current short message data, obtains the content of monitoring.
2) judge whether current data belongs to set of keywords,, then continue execution in step 3, otherwise change step 10 if belong to set of keywords.
3) judge that a certain keyword mates fully in current data and the set of keywords, coupling is then changeed step 12, otherwise continues execution in step 4.
4) initialization keyword subset is as the space of keyword computing.
5) copy the keyword of coupling, the data of first unit length removed in each keyword, obtain new keyword, form keyword subset.
6) judge that whether short message also has data etc. pending,, then change step 13, otherwise continue execution in step 7 if there are not data etc. pending.
7) move a unit length behind the data pointer.
8) judge whether current data belongs to keyword subset,, then continue execution in step 9 if belong to keyword subset; Otherwise change step 2.
9) judge whether the keyword of coupling is fully arranged in the keyword subset,, then change step 12, otherwise change step 5 if there is the keyword of coupling fully.
10) judge that whether short message also has data etc. pending, if data need to handle, then continues execution in step 11, otherwise changes step 13.
11) move a unit length behind the data pointer, change step 2.
12) the match is successful, and the keyword of record coupling sends message to stored program, and the keyword of short message data and coupling is added in the database, changes step 14.
13) coupling is unsuccessful.
14) call and withdraw from.
For example: in communication process, the content of short message that the party A-subscriber issues the party B-subscriber is " CABA ".The set of keywords of setting in the monitoring system is combined into: { ABA, ABB, ABC, ABD, BBA, BBB, BBC, BBD}; According to top algorithm, the process of carrying out content match is as follows:
1. take out the current data " C " of short message, judge and do not belong to set of keywords; Move behind the data pointer, continue coupling.
2. the current data of short message is " A ", judges it and belongs to set of keywords, but not exclusively mate; According to current keyword draw keyword subset BA, BB, BC, BD} moves behind the data pointer, continues coupling.
3. the current data of short message is " B ", judges it and belongs to keyword subset, but not exclusively mate; According to current keyword subset draw keyword subset A, B, C, D} moves behind the data pointer, continues coupling.
4. the current data of short message is " A ", judges it and belongs to keyword subset, and mate fully, shows that the match is successful, and the keyword of coupling is " ABA ".
As for the mobile subscriber who is added into because of the keyword coupling in the monitoring system, its tracking depths can be set according to systematic unity, has the tracking attribute of same levels, also can be distinguished according to keyword, gives different tracking attributes.
Figure 19 is a kind of schematic diagram of organizing according to calling number storage short message data.
Attribute word that can index in the database comprises that calling number, called number, calling number send to the short message sum of called number, the detail time of every short message, the keyword that the match is successful according to these attribute words, can index content of short message easily.
Wherein, the short message sum between calling number and called number is an important information element, and the short message communication process between relevant target complex not only can be found and monitor to the intelligent-tracking algorithm in the coupling system automatically; And some target and the relation between major heading that can pick out in the target complex are close and distant.
