Description
Technical field
The present invention relates to the note treatment technology of the communications field, system, the device and method of particularly a kind of monitoring spam and processing.
Background technology
Along with development of Communication Technique, communication network operator provides diversified applied business in communication network, and one of them is exactly a note.Along with the user who uses note is more and more, illegal refuse messages is also more and more.How the network side of communication network monitors these refuse messages and deletion, also becomes one of problem that the communication network side will solve.
At present, communication network side monitoring rubbish note and the mode handled mainly through these three kinds of keyword filter type, flow control mode and blacklist modes, specifically describe as follows:
Keyword filter type: keyword is set in advance in the communication network side; The communication network side is mated the keyword and the short message content that are provided with, if mate successfully receiving before note do not transmit; Confirm that then this note is a refuse messages, then with this SMS interception and deletion; If do not match, then be transmitted to receiving terminal;
Flow control mode: be directed against the note quantity thresholding that send at a terminal in setting-up time in the setting of communication network side; As 1 hour 200; The communication network side is monitored the note quantity that same transmitting terminal sends in setting-up time; If when surpassing the note quantity thresholding that sends in the setting-up time, then tackle of note and the deletion of this transmitting terminal in follow-up transmission; If do not surpass the note quantity thresholding that sends in the setting-up time, then the note with this transmitting terminal is transmitted to receiving terminal;
The blacklist mode: in the communication network side blacklist is set, the communication network side is receiving before note do not transmit, the transmitting terminal of confirming to send this note whether in set blacklist, if, then with this SMS interception and deletion; If not, then be transmitted to receiving terminal.
In technique scheme, when adopting the keyword filter type that refuse messages is monitored and handled, mistake monitoring and leakage monitoring are higher.This be because; Keyword to short message content and setting carries out in the matching process; Be based on Chinese keyword coupling; Such as: the keyword of setting is " invoice " etc., when refuse messages can be evaded set keyword when sending, adopts " sending out * wafts ", " sending out one wafts " (middle " one " for Chinese), " invalidated ticket " or obfuscation and splicingization words such as " sending out boomerang "; Promptly add non-Chinese character, and utilize means such as Chinese homonym and shape similar word to evade the set keyword monitoring in pass at refuse messages.The content that the keyword of communication network side setting can't mate these refuse messages, but for receiving terminal, get in touch with the context of these refuse messages, be readily appreciated that these refuse messages.
A complete instance: the content of refuse messages is " our company opens various regular invalidated tickets in generation, intentionally R. S. V. P. Mr. Li 1391111111 ", at this moment adopts the keyword of " invoice " just can't monitor this refuse messages.In addition, also have some to have the refuse messages of the content that keyword is put upside down,, can't adopt the keyword filter type to monitor such as " ticket is sent out ", but for receiving terminal, from the context, just be readily appreciated that the refuse messages content.Another complete instance: the content of refuse messages is " machine is played regular ticket and sent out; having needs to get in touch Miss Zhang 1581223333 "; Adopt the keyword of " invoice " just can't monitor this refuse messages, but receiving terminal just can be readily appreciated that this refuse messages content.In order to overcome these problems; Keyword to short message content and setting carries out in the matching process; Setting is mated based on the phonetic of Chinese keyword conversion; Though this can avoid the use of homonym be content refuse messages evade the keyword matching problem, for using homograph or keyword to put upside down refuse messages, but still can evade the keyword coupling as content.
In technique scheme; The monitoring that the flow control mode that is adopted carries out refuse messages is a property afterwards with handling; Surpass the note quantity thresholding that sends in the setting-up time when monitor the note quantity that same transmitting terminal sends in setting-up time; And then tackle of note and the deletion of this transmitting terminal in follow-up transmission, a large amount of refuse messages that this transmitting terminal sends in earlier stage successfully are transmitted to receiving terminal by the communication network side.
In such scheme, the blacklist mode that is adopted is carried out the monitoring and the processing of refuse messages, and the process of setting up blacklist is veryer long, and the main mode of still verifying through manual work in the communication network side is carried out.
The communication network side usually is used in combination above-mentioned three kinds of modes for more effectively monitoring and processing note, and the technical scheme when being used in combination mainly contains following several kinds:
First kind of technical scheme: in the communication network side blacklist is set simultaneously, is directed against note quantity thresholding and the keyword that send at a terminal in setting-up time.The communication network side when receiving note, the transmitting terminal that at first confirm to send this note whether in blacklist, if; Then tackle this note and deletion, if not, then monitor the note quantity that same transmitting terminal sends in setting-up time; If do not surpass, just transmit this note, if surpass; The keyword and the short message content that are provided with are mated, if mate successfully, the transmitting terminal that then will send this note is arranged in the blacklist; If do not match, then be transmitted to receiving terminal;
Second kind of technical scheme: the communication network side is provided with dynamic blacklist; Just through manual analysis and refuse messages report information; Dynamically arrange blacklist, the communication network side is receiving before note do not transmit, and whether the transmitting terminal of confirming to send this note is in set dynamic blacklist; If, then with this SMS interception and deletion; If not, then be transmitted to receiving terminal;
The third technical scheme: in the communication network side blacklist is set simultaneously, is directed against note quantity thresholding and the keyword that send at a terminal in setting-up time.The communication network side when receiving note, the transmitting terminal that at first confirm to send this note whether in blacklist, if; Tackle this note and deletion, if not, monitor the note quantity that same transmitting terminal sends in setting-up time; If do not surpass, just transmit this note, if surpass; The keyword and the short message content that are provided with are mated,, tackle this note and delete this note if mate successfully; If do not match, be transmitted to receiving terminal.
In above-mentioned association schemes monitoring and disposal of refuse note; For first kind of technical scheme: the prerequisite that adopts flow control mode to filter as keyword; Caused before carrying out the keyword filtration; The refuse messages of some issues, and when adopting the keyword filter type, False Rate and misdetection rate are all higher; For second kind of technical scheme, set blacklist to set up process very long, also be treatment mechanism afterwards; For the third technical scheme, three kinds of modes are independently carried out respectively, do not overcome three kinds of existing self-defects of mode.

Fig. 3 is the method flow diagram of monitoring spam provided by the invention and processing; Keyword derived sequence and the doubtful degree of refuse messages that the basic keyword rule that setting is made up of the keyword that is associated, the keyword that basis is associated obtain according to partials, similar shape or font disassembly principle, its concrete steps are:
In this step, if not, expression is smaller or equal to scope under the doubtful degree of set refuse messages;
In this embodiment, adopt before set basic keyword rule rule matees short message content, also comprise: the non-Chinese character deletion in the short message content of this note.
In this embodiment, the method flow that calculates the doubtful value of refuse messages of mating is as shown in Figure 4, and its concrete steps are:
In the present invention, set basic keyword rule is to judge one group of basic keyword combination that is associated of refuse messages, as: rule 1: " generation opens "+" invoice "; Rule 2: " Falun Gong "; Rule 3: " gun "+" buying on behalf " or the like.Set keyword derived sequence is to be unit with each keyword in every basic keyword rule, is target with the word of forming each keyword, with these keywords according to homophonic, similar shape or/and principles such as font fractionation are carried out the keyword formation of deriving.Here; After keyword is derived; It is a speech that a keyword possibly derived; Each keyword that derives all correspondence is provided with a doubtful value p of refuse messages (0＜p＜1), and p reaches the frequency that in refuse messages, occurs by the communication network lateral root according to the degree commonly used of this keyword in Chinese character and preestablishes.Such as the keyword " gun " in above-mentioned regular 3; Carry out after keyword derives; Form derived sequence " rifle (0.3) ", " robbing (0.1) ", " choke (0.1) ", " wooden storehouse (0.5) ", " deep blue (0.1) " with " rifle " word ..., reach " skill (0.1) " with " propping up " word formation derived sequence " (0.2) ", " only (0.1) " ....
In the present invention, the doubtful degree of refuse messages P judges whether note is the metric of refuse messages, and it is more than or equal to 0; As greater than the doubtful refuse messages thresholding T1 that sets,, then think refuse messages as 80%; As in being set at certain limit the time and note when dropping in the scope after judging, like 50%＜p＜80%, then think doubtful refuse messages; If smaller or equal to 50%, can think non-refuse messages.
Lift an object lesson explanation and calculate the doubtful value process of refuse messages of coupling.
Basic keyword rule: " gun "+" buying on behalf "
Keyword derived sequence: keyword " gun ": " rifle " derivative sequence { rifle (0.5) is robbed (0.1), choke (0.1), wooden storehouse (0.5), deep blue (0.1) }; " prop up " derivative sequence { (0.1), only (0.1), skill (0.1) };
Keyword " is bought on behalf ": " generation " derivative sequence { in generation (0.1), band (0.1) cuts down (0.1), borrows (0.1) bag (0.1) }; " purchase " derivative sequence { purchase (0.1), ditch (0.1), hook (0.1), enough (0.1), shellfish is colluded (0.5) }.
The content short message content that the communication network side joint is received note is " & band & shellfish one by one colludes all kinds of wooden storehouses and props up one by one, and having needs to get in touch Wang 1381199900 ", (remarks, " " is Chinese character one in the foregoing, is not English horizontal line character).Become after having passed through the deletion preliminary treatment of non-Chinese character: " band is purchased all kinds of wooden storehouses one by one and propped up one by one, and having needs to get in touch Wang 1381199900 ".
According to matching algorithm, the matching result that keyword " is bought on behalf " is band (0.1), position 1, and shellfish is colluded (0.5), position 6; So P=0+0.1+0.5/ (6-1)=0.2; The matching result of keyword " gun " is wooden storehouse (0.5), position 10, (0.1), so position 15 is P=0.2+0.5+0.1/5=0.72; Finally, the doubtful value of the refuse messages of this note is 0.92, has surpassed the doubtful degree 80% of set refuse messages, so be judged as refuse messages.
In the present invention; Can also keyword filter type that provided and the flow control mode that is provided be combined to carry out the monitoring of refuse messages; Certainly, also can before or after association schemes, further adopt the blacklist filter type further refuse messages to be monitored.
Fig. 5 is the method embodiment flow chart of monitoring spam provided by the invention and processing, and its concrete steps are:
After step 501, communication system network receive note, adopt the blacklist that is provided with that the transmitting terminal that sends this note is mated,, confirm that then this note is a refuse messages, deletes and report result of determination if the match is successful; If not, execution in step 502 then;
In this step, suppose that setting-up time is 30 seconds, statistics is sent the note quantity of the transmitting terminal transmission of this doubtful refuse messages in 30 seconds, if surpass the threshold value of setting, then execution in step 507; If not, execution in step 508;
In this step, in the time period of monitoring, continuation will be carried out buffer memory through the refuse messages that sms center/short message network receives from this terminal as transmitting terminal;
Lift the explanation of object lesson: the communication network side joint is received 5 of the notes that transmitting terminal sends; Wherein one is judged as doubtful refuse messages; Then this is judged as the note of doubtful refuse messages to the communication network side with buffer memory, starts to set timer, and the time is 30 seconds.In 30 seconds,, just continue buffer memory if continue to receive the note that this transmitting terminal sends and be judged as doubtful refuse messages; By the time timer is to constantly, and whether the doubtful refuse messages number that this transmitting terminal of statistics institute buffer memory sends surpasses the thresholding of setting 3; If judge that then these doubtful refuse messages are refuse messages, if not; Then doubtful refuse messages is confirmed as non-refuse messages, transmit processing.
Whether in the present invention, adopt keyword filter type monitoring short message, can not 100% affirmation be refuse messages often.This is because the refuse messages content is easy to change; To mate the keyword in the basic keyword rule fully; It is the comparison difficulty; For the part match condition that obtains according to the keyword derived sequence, just need determine whether to be doubtful refuse messages or refuse messages according to its metric, carry out different processing procedures.Such as: basic keyword filtering rule is " invoice "+" generation opens "+" contact ", and short message content has mated " invoice " wherein+" contact ", then this note is located doubtful refuse messages.
More than lift preferred embodiment; The object of the invention, technical scheme and advantage have been carried out further explain, and institute it should be understood that the above is merely preferred embodiment of the present invention; Not in order to restriction the present invention; All within spirit of the present invention and principle, any modification of being done, be equal to replacement and improvement etc., all should be included within protection scope of the present invention.
