Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for checking validity of a short message source, a terminal, and a communication system.
Background
Along with the transverse fraud short messages sent by the pseudo base station, the number changing software and other modes, a sender can set a calling number at will, and a mobile phone user cannot judge whether the received short messages are sent by real calling. The pseudo-calling short message is often sent by ports which pretend to be 10086 and 5-bit main ports of a bank, even 110 and the like with extremely high daily trust of users, the normal short message communication of mobile users is seriously influenced, and the vicious events of pseudo-short message fraud often occur. Although the mobile network operator has increased the interception strength of the pseudo-calling number short message, the existing means has poor interception effect due to the objective limitation of the technology. For example, the pseudo base station short message is a pseudo short message sending mode which does not pass through a mobile operator communication network at all and cannot be intercepted on an operator network.
Currently, tracing the source of the abnormal short message is mainly performed by the following method:
the method comprises the following steps: and manually complaining suspected abnormal short messages by the mobile phone user, and manually checking by customer service. The method determines whether the suspected abnormal short message is a normal short message or not by the customer service receiving the customer complaint order and performing data query and analysis according to the dimensions of complaint time, short message calling and called, short message content and the like. The method has the following advantages and disadvantages: the method has hysteresis, the suspected abnormal short messages can not be found before the users find the suspected abnormal short messages through customer complaints, the complaint users only receive a small part of the abnormal short messages, and the abnormal short messages can have negative effects on the users after batch manual complaints occur. The manual judgment of the abnormal false short messages requires professional short message knowledge, and because the length of the related service chain and the difficulty of source positioning are increased, common customer service personnel cannot process the abnormal false short messages and need to transfer to the professional short message maintenance personnel for processing, the processing process is long in time consumption and large in manpower consumption. When a customer complains about a suspected abnormal short message, only partial information displayed on the mobile phone terminal can be provided, background key information such as a short message sending center number cannot be seen, and source judgment is inconvenient.
The second method comprises the following steps: the method mainly authenticates the passing short message and intercepts the abnormal short message on the network element of the short message system at the core network side of an operator. The method has the following advantages and disadvantages: the operator core network side intercepts part of abnormal short messages through local data authentication and other modes, but because the pseudo port short messages are usually sent through network system loopholes, the effect of intercepting at the core network side alone is poor. In addition, the pseudo base station short message does not pass through the operator network completely, and the network side cannot recognize and intercept.

The above-mentioned short message source tracking information according to the embodiment of the present invention may specifically include: the short message processing method comprises the steps of calling number, called number, receiving time, short message length, short message center number and the like, so that whether the short message source is legal or not can be determined by checking short message processing information recorded in a short message network element on the basis of the short message source tracking information.
As can be seen from the structures shown in fig. 1 and 2, the short message network element according to the embodiment of the present invention may specifically be a short message center, a short message gateway, and the like, and in the following description, a short message network element is taken as an example of the short message center (which does not prevent the technical solution provided by the embodiment of the present invention from being implemented in the short message gateway).
In an embodiment, the method for verifying the validity of a short message source provided in the embodiments of the present invention may specifically relate to the stages of a short message source tracking information extraction process, a short message source validity verification process, a verification result feedback process, and the like.
In the process of extracting the short message source tracking information, when the terminal receives a short message, the App installed in the terminal can automatically extract the information of the short message, such as quintuple information of 'calling number, called number, receiving time, short message length, short message sending center number' and the like shown in table 1, and transmit the information to the short message source tracking platform through a transmission network such as a GPRS network.
TABLE 1
| Calling number | Called number | Receiving time | Length of short message | Number of short message sending center |
| OrgAddr | DestAddr | RecvTime | Length | SCADDR |
In the process of verifying the validity of the short message source, that is, in the process of determining whether the short message source is valid by verifying the processing information recorded in the short message center based on the short message source tracking information, at least one of verifying the information of the short message center, verifying the recorded information corresponding to the type of the short message in the short message center, and verifying the validity of the short message sender may be specifically included, or any sequence combination of all the above verifying processes may be included.
In an embodiment, the process of verifying the validity of the short message source may be to verify the information of the short message center, and after the verification is passed, to verify the record information corresponding to the type of the short message in the short message center.
Specifically, in the process of checking the information of the short message center, the identification and verification of the validity of the source of the short message can be realized by checking the number of the short message center, checking the calling number, checking whether the signaling corresponding to the short message is recorded in the short message center, and the like.
In the checking of the record information corresponding to the short message type in the short message center, the method specifically includes the following processing steps:
determining first signaling information corresponding to the short message in a short message center based on the short message source tracking information;
determining the short message type based on the first signaling information;
and checking the second signaling information corresponding to the short message type.
The related first signaling information may specifically include a calling number, a submission account number, a submission Mobile Switching Center (MSC) Identification (ID)/IP address, and the like, and the second signaling information corresponding to the short message type may specifically include a submission account number, a submission MSC ID/IP address, a service code, and the like.
The process of verifying whether the short message sending party is legal can be specifically used for verifying at least one of the submitted account number, the submitted IP address and the service code of the short message sending party so as to determine whether the short message sending method is legal.
A detailed description will be given below of a specific example of the procedure for verifying the validity of the source of the short message according to the embodiment of the present invention.
As shown in fig. 4, this embodiment may specifically include:
whether the short message center number in the short message quintuple information extracted by the terminal side is legal or not can be judged for the first time.
The number of the short message center is the mark of the short message center which is finally sent to the terminal short message, if the number of the short message center is not in the list of the legal number of the short message center, the number can be directly judged to be an abnormal short message, namely the source of the short message is illegal.
If the number of the short message center is legal, the calling number in the quintuple information can be compared with the calling authentication number segment table of the short message center, the legal calling is definitely contained in the calling authentication number segment table of the short message center, and if the calling is not in the calling authentication number segment table, the calling is not a short message which is normally issued by the short message center, and the calling can be judged as an abnormal pseudo short message. If the two are normal, the next step is carried out to continue the analysis.
And according to the number of the found short message center, screening a short message signaling related to the short message in the short message center according to the calling number, the called number, the receiving time and the short message length in the quintuple information, and if no signaling record of the short message exists in the short message center, judging the short message is an abnormal pseudo short message issued by an abnormal channel.
If the signaling record of the short message exists in the short message center, the type of the short message is judged through a calling number, a submission account number and a submission MSC ID/IP address (namely first signaling information) in the short message signaling inquired by the short message center.
After determining the type of the short message, whether the source of the short message is legal or not can be determined based on the second signaling information. Specifically, the method comprises the following steps:
when the type of the short message is a point-to-point short message, judging whether a mobile switching center mark is submitted in a short message signaling, an account number is submitted and a point-to-point short message office data rule in a short message network element is judged, if so, judging that the source of the short message is legal, and if not, judging that the source of the short message is illegal;
when the short message is an industry short message, judging whether a group client submitted account/IP address, a service provider submitted account/IP address and a service code in a short message signaling conform to the data rule of an industry short message office in an industry short message gateway or not, if so, judging that the source of the short message is legal or not;
when the short message is an intercommunicated short message, judging whether an operator submitted account/IP address and an operator calling number section in a short message signaling conform to the data regulation of an intercommunicated short message office in an intercommunicated short message gateway or not, if so, judging that the source of the short message is legal or not;
when the short message is an AO short message, judging whether a submitted account number and an IP address in a short message signaling are legal or not, if so, judging that the source of the short message is legal or not;
when the short message is an international short message, judging whether a submitted account number and an IP address in a short message signaling are legal or not, if so, judging that the source of the short message is legal or not;
and when the short message is a dream network short message, judging whether a service provider submitted account/IP address and a service code in a short message signaling conform to central office data rules of a dream network short message gateway, if so, judging that the source of the short message is legal, and if not, judging that the source of the short message is illegal.
Through the verification, the short message with abnormal source can be accurately identified in real time, efficiently and at low cost.
And after automatically judging whether the short message source is legal, the short message source tracking platform automatically pushes the determined result to the terminal. For short messages with illegal sources, the App in the terminal can be reminded in a mode of popping up a window and the like.
In an embodiment of the present invention, a process of tracing back the transmission trajectory of the recombined short message may also be included.
The process can be specifically executed before determining whether the short message is legal or not, so that the validity of the short message source is checked based on the short message sending track.
Specifically, the short message source tracking platform performs deep content inspection (DPI) on short message signaling of a short message center and a short message gateway according to the collected five-tuple information of the short message, recombines data flow in a signaling set, and extracts circulation track information in the short message sending process. And starting from the last network element, namely a short message center, for sending the short message to the terminal, extracting short message processing signaling in the network elements step by step, recombining the short message sending track, and forming a complete sending track from the final receiving terminal to the short message submitting party.
The tracing method can be concretely as follows:
step 1: and identifying and determining the short message center according to the short message center number in the short message quintuple information.
If the number of the short message sending center is illegal, directly judging that the short message is an abnormal short message; if the short message is a legal short message center number, the short message center screens a short message signaling according to the calling number, the called number, the receiving time and the short message length, and checks the information in the following table 3 of the short message:
TABLE 2
| Commit time | Delivery time | Short message submission account | Issuing an account number | Submitting MSC ID/IP address |
| SubmitTime | SendTime | OrgAccount | DestAccount | OrgMSC/OrgIPAddr |
Whether the point-to-point short message exists or not can be judged according to the information of the submitted account number, the calling number, the submitted IP address and the like, if the point-to-point short message exists, a complete short message sending track is obtained, and the intelligent analysis process of whether the source of the short message is legal or not can be directly entered; if the short message is not a point-to-point short message, the processing network element of the previous hop is determined according to the information of the short message submission account number, the submission MSC ID/IP address and the like, and the short message sending track is continuously traced.
Step 2: the processing network element of the previous hop of the short message center is usually a short message gateway, the short message gateway of the previous hop is confirmed according to the information of the submission account number, the submission IP address and the like checked and verified by the short message center, the signaling of the short message gateway is screened according to the short message quintuple information, and the information of the submission account number, the submission IP address and the like at the short message submission source is checked and verified.
If the last-hop processing network element is the short message sender, ending the track tracing; otherwise, the step 2 is iterated, and the upper-level short message gateway is continuously checked until a complete sending track from the final receiving user terminal to the short message submitting party is formed.
The finally formed complete transmission trajectory of the short message from the receiving user terminal to the short message submitting party is shown in table 3 below:
TABLE 3
That is, in the embodiment of the present invention, the method may further include: and recombining the sending track of the short message based on the short message source tracking information and the processing information recorded by the short message center.
