The main subelement of handling is used to preserve the call spam user ID that the man-machine interaction subelement is sent.
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with drawings and the specific embodiments.
Fig. 3 is the flow chart of harassing call filtering in the present invention.Referring to Fig. 1, Fig. 2 B and Fig. 3, utilize system of the present invention, the inventive method realizes that the process of harassing call filtering may further comprise the steps:
Step 301: the main processing in the subelement in call spam filtering unit is provided with blacklist, and fixed call spam user ID is arranged in the blacklist.
Here, the present invention can directly be arranged on fixed call spam user ID in the blacklist of main processing subelement, perhaps, also can its call spam user ID of determining be sent to the main subelement of handling by the man-machine interaction subelement by the user, the main subelement of handling is kept at fixed call spam user ID in the blacklist again.
Step 302: the signaling process subelement in the call spam filtering unit, receive the message related to calls that sends to terminal, judge the current talking state that whether has been in of terminal, if then execution in step 303, otherwise, execution in step 306.
Here, if the current talking state that has been in of terminal, show that then current terminal just converses as caller and other users, perhaps, current terminal as called be defined as non-call spam producer and converse, therefore, need not to carry out the process of follow-up harassing call filtering,, show that then current terminal is as the called calling that receives other users first if current terminal also is not in talking state, therefore, need to carry out the process of follow-up harassing call filtering.
Step 303: the signaling process subelement judges whether the current message related to calls that receives is the message that disconnects conversation type, if then execution in step 304, otherwise, execution in step 305.
Here, the message of described disconnection conversation type can be exemplified as: message such as BYE message, CANCEL and 4XX.
Step 304: the signaling process subelement is updated to not talking state with the state of terminal, and the current message related to calls that receives is sent to terminal, finishes current flow process.
Step 305: the signaling process subelement directly is sent to terminal with the current message related to calls that receives, and finishes current flow process.
Step 306: the signaling process subelement judges whether the current message related to calls that receives is that message is set up in session, if then execution in step 307, otherwise, carry out turning to step 305.
Here, if communication protocol is session initiation protocol (SIP), so, it can be INVITE that message is set up in described session.
Step 307: the signaling process subelement extracts calling subscriber identification from current received message related to calls, and the calling subscriber identification that is extracted is sent to the main subelement of handling.
Step 308: whether can find received calling subscriber identification in the call spam user ID of main processing subelement judgement in blacklist, if then execution in step 309, otherwise, execution in step 311.
Step 309: the main message that rejects response of subelement structure of handling is sent to the signaling process subelement with this message that rejects response.
Step 310: the message that rejects response that the signaling process subelement will receive is sent to the calling subscriber who sends message related to calls, finishes current flow process.
Here, by the main processing of handling subelement and signaling process subelement, if the calling subscriber is the call spam user, so, can directly the message that rejects response that receives be sent to the calling subscriber, thereby avoid the terminal jingle bell, avoid the terminal use to be bothered by call spam.
Step 311: main processing subelement will be transmitted indication and be sent to the signaling process subelement.
Step 312: after the signaling process subelement receives and transmits indication, the state of terminal is updated to talking state, and the current message related to calls that receives is sent to terminal.
In step 304, step 305 and step 312, after terminal receives message related to calls, then can carry out corresponding processing according to message, such as, in step 304, terminal disconnects the session connection with other users, in step 312, terminal is carried out with host subscriber's terminal and is set up the session connection processing, to called subscriber's ring.
So far, then realized carrying out filtering the process of avoiding the user to be disturbed for call spam.
In the present invention, in order to guarantee that the terminal use can receive its good friend's calling, can white list be set main the processing in the subelement, in above-mentioned steps 301, the user ID as the good friend that the user can also determine it is sent to the main subelement of handling by the man-machine interaction subelement, and the main subelement of handling is kept at fixed user ID as the good friend in the white list; And, in step 308, judge in blacklist, do not find calling subscriber identification after, can further include: the main subelement of handling judges whether can find calling subscriber identification in white list, if can find, then reliable information is sent to the man-machine interaction subelement, the man-machine interaction subelement is called out this to reliable information and is offered the user, after this, the user calls out reliable information according to this, can determine that then current calling is not a call spam, therefore, can answer relievedly.
In the present invention, for the calling of some doubtful call spam, all right warning terminal user of the present invention, its specific implementation is: main the processing in the subelement gray list being set, being used to preserve suspection and being the user ID of call spam; In above-mentioned steps 301, according to the setting of user by man-machine interaction unit, or, according to the report of other equipment, lead in the gray list of handling in the subelement suspecting for call spam user's sign is kept at; In step 308, judge in blacklist, do not find calling subscriber identification after, can further include: the main subelement of handling judges whether can find calling subscriber identification in gray list, if can find, then trustless information is sent to the man-machine interaction subelement, the man-machine interaction subelement is called out this to trustless information and is offered the user, the user calls out trustless information according to this, can determine that then current calling may be a call spam.After this, after the user is call spam by the content of answering definite this calling, the user can be to the indication of man-machine interaction subelement input call spam, the man-machine interaction subelement is sent to the main subelement of handling with the call spam indication, main processing subelement is deleted the calling subscriber identification in the gray list, and calling subscriber identification is kept in the blacklist.
Fig. 4 will suspect that according to warning information sign for the call spam user is kept at the flow chart in the gray list in the present invention.Referring to Fig. 4, in the present invention, the warning information that call spam filtering unit can be sent according to other equipment will be suspected for the user ID of call spam is kept in the gray list, is example with employing Session Initiation Protocol message, and its specific implementation process may further comprise the steps:
Step 401: the signaling process subelement in the call spam filtering unit receives carrying by the alarm information of report user ID that other equipment send, and this alarm information is sent to the main subelement of handling.

Step 402: the main subelement of handling extracts the user ID of sending this alarm information from received alarm information, judge whether can find the user ID of sending this alarm information in white list, if, then execution in step 403, otherwise, abandon this alarm information, finish current flow process.
Step 403: whether can find the identify label of self in the VIA field of main processing subelement judgement in alarm information, if, then directly abandon this alarm information, otherwise, execution in step 404.
Step 404: the main processing extracted the user ID of being reported in the warnning field of subelement from alarm information, whether judgement can find the user ID that this is reported in blacklist, if then directly abandon this alarm information, otherwise, execution in step 405.
Step 405: the main subelement of handling judges whether can find the user ID of being reported in white list, if, then directly abandon this alarm information, otherwise, execution in step 406.
Step 406: the main subelement of handling judges whether can find the user ID of being reported in gray list, if then execution in step 407, otherwise, execution in step 409.
Step 407: main handle that subelement will be set at being added 1 by the value of the counter of report user ID, whether the value of judging this counter greater than the frequency threshold value that sets in advance, if then execution in step 408, otherwise, direct execution in step 410.
Step 408: the user ID that main processing subelement will be reported adds in the blacklist, and will offer the user, execution in step 410 at this trustless information of being reported user ID by the man-machine interaction subelement.
Step 409: the user ID that main processing subelement will be reported adds in the gray list, and the value at the counter of being reported user ID that will set in advance adds 1.
Step 410: the main subelement of handling is that the value of tt1 field subtracts 1 with hop count in the received alarm information, judges then current hop count is whether the value of tt1 field is 0, if, then finish current flow process, otherwise, execution in step 411.
Step 411: main handle subelement with all user ID except that the sender of this alarm information in the white list as the called subscriber, construct one at this called subscriber and carry, the alarm information of being constructed is sent to the signaling process subelement by the alarm information of report user ID.
Here, when main processing subelement is constructed alarm information, VIA field in the alarm information that it can be received and warnning field, and current tt1 field directly copies in the alarm information of being constructed.
Step 412: the signaling process subelement will be led and handle the alarm information that subelement sends and be sent to each called subscriber.
In the present invention, the user can be by man-machine interaction subelement report call spam producer, such as, call out fly-by-night information the user according to this that provides, after receiving calls, if determine that this is called out is call spam, the user then can be after answering this calling, and before answering next time, the calling subscriber who reports this calling is the call spam producer, call spam filtering unit can the user of active in white list send alarm information at user's report, and its specific implementation process can may further comprise the steps referring to shown in Figure 5:
Step 501: the man-machine interaction subelement in the call spam filtering unit receives the sign of being reported the user of user's input.
Step 502: the sign by the report user that the man-machine interaction subelement will receive is sent to the main subelement of handling.
Step 503: the master handles subelement and judges whether to find the current sign of being reported the user that receives in white list and gray list, if then execution in step 504, otherwise, direct execution in step 505.
Step 504: the main subelement of handling is reported user's sign from finding current user's the sign of being reported with deleting this list.
Step 505: the main subelement of handling is with current being added in the blacklist by report user's sign of receiving.
Step 506: main processing subelement as the called subscriber, is constructed all user ID in the white list one at this called subscriber and is carried by the alarm information of report user ID, and the alarm information of being constructed is sent to the signaling process subelement.
