Description
Technical field
The present invention relates to number detection technique in the multimedia message, relate in particular to the detection method of false transmitted number in a kind of multimedia message.
Background technology
Along with the high speed development of the communication technology, portable terminal such as mobile phone occupy more and more important position in daily life, in the mobile phone integrated function also more and more.At present, link up, become a kind of important means of linking up between the user by sending multimedia message between the mobile phone.
But the situation of cell phone multimedia message swindle and escape rate emerges in an endless stream, and brings very big harm for users and operator.Some utilize the leak of network when the victim sends out multimedia message, by certain technological means, make the transmission number of multimedia message be shown as victim relatives' number, utilize victim's paralysis psychology, gain victim's money by cheating; Also some people utilizes the leak of network, mass-sends a large amount of advertising messages to a plurality of victims, but the expense that sends advertising message is but paid by the victim.
At present, in order to realize the transmitting-receiving of multimedia message, there is Internet protocol (IP in Virtual network operator one side, InternetProtocol) signaling monitoring system, adopt the mode of IP harvester to gather signaling data from the IP signaling link of GN or GW interface, and signaling data put in order, analyzes and add up, various online of detail knowledge the whole network and sending and receiving multimedia message process in view of the above, and carry out profound network management, service management, user management and the network optimization, the network planning, network design.
In the said process; usually can generate event detail records (TDR according to certain rule to the signaling data that collects; Transaction Detail Record); it is synthetic that this process that generates TDR is called incident again; the synthetic incident that produces of incident; for signaling monitoring system provides most basic initial data, therefore, incident is synthetic to be that the whole signaling monitoring system is carried out the basis that follow-up data is analyzed.
Figure 1 shows that the event synthesizing method of GN interface, comprise the steps:
Step 101: GN interface IP signaling data are gathered.
Wherein, continue to carry out for the collection of signaling data, collection specifically how to carry out described data belongs to known technology, repeats no more here always.
Step 102: read a signaling of being gathered, judge whether this signaling has adopted User Datagram Protoco (UDP) (UDP on the IP layer, User Datagram Protocol) and the port of udp protocol whether be 2152 or 2123, if, then described signaling data is put in the synthetic handling process of GN incident into execution in step 103; Otherwise, abandon current signaling, the judgement described in next the bar signaling that continues to read collection carry out this step.
Step 103: the type of message according to signaling extracts corresponding characteristic value, and according to the composition of characteristic value, sets up or fill GN TDR.
Wherein, the signaling of GN interface can be divided into following type of message: set up packet data protocol context request (Create PDP Context Request), set up block data protocol context answer (Create PDPContext Response), delete packet data protocol context request (Delete PDP ContextRequest), delete block data protocol context answer (Delete PDP Context Response), tunnel packet data cell (T-PDU) etc.And comprise WAP (wireless application protocol) (WAP among the T-PDU, WirelessApplication Protocol), HTML (Hypertext Markup Language) (HTTP, Hypertext Transfer Protocol), Multimedia Message service environment type of messages such as (MMSE, Multimedia Messaging Service Environment); WAP further is included as again: wireless transmission protocol (WTP, Wireless TransactionProtocol) and WSP (WSP, Wireless Session Protocol), and wherein WTP is a bottom, WSP is the upper strata.
If the described signaling that reads in the step 102 is Create PDP Context Request, then enter the state of foundation, the IP address (SGSN Address for user traffic) that is used for data according to SGSN, data tunnel Endpoint ID (TEID DATA, Tunnel Endpoint Identifier data) composite character value 1, the IP address (SGSN Address for signaling) that is used for signaling according to SGSN, control Tunnel End Point Identifier (TEID CONTROL PLANE, Tunnel Endpoint Identifier control plane) composite character value 2, set up a GN TDR, the needed information of GN TDR in the signaling is deposited among the GN TDR, afterwards, return step 102.
Here, the needed information of described GN TDR comprises user's mobile station ISDN number (MSISDN, Mobile Station ISDN Number) etc.
If signaling is Create PDP Context Response, according to purpose IP, tunnel endpoint identifier (TEID) composite character value, search GN TDR according to characteristic value, if can find, deposit the needed information of GN TDR in the signaling in GN TDR, and be used for the IP address (GGSN Addressfor user traffic) of data according to GGSN, TEID DATA composite character value 1, the IP address (GGSN Address for signaling) that is used for signaling according to SGSN, TEID CONTROL PLANE composite character value 2 is added to characteristic value 1 and characteristic value 2 characteristic value of GN TDR; Afterwards, return step 102.
In this case, comprise two characteristic values that GN TDR is added when setting up, will have four characteristic values among the GN TDR.The needed information of the TDR of GN described in the signaling comprises: information such as the transmission number of multimedia message, receiving number, transmitting time.
If signaling is Delete PDP Context Request, according to source IP, TEID composite character value 1, purpose IP, TEID composite character value 2 according to the TDR incident that characteristic value is searched GN, as long as one of them characteristic value can find the TDR of GN, are filled GN TDR; Afterwards, return step 102.
If signaling is Delete PDP Context Response, according to source IP, TEID composite character value 1, purpose IP, TEID composite character value 2, search GN TDR according to characteristic value, as long as one of them characteristic value can find GN TDR, then close GN TDR,, then abandon this signaling if do not find GN TDR; Afterwards, return step 102.
If signaling is T-PDU, according to purpose IP, TEID composite character value, search GNTDR according to characteristic value, if find GN TDR, then write down this signaling, otherwise, abandon this signaling; Afterwards, return step 102.
By above description to five kinds of different messages type of process methods as can be known, incident is synthetic to comprise three states, is respectively: set up GN TDR, fill GN TDR and GN TDR end-of-fill and send.
In addition, specifically how to carry out described characteristic value synthetic, how set up or search GNTDR according to characteristic value and all belong to known technology, repeat no more here.
The above is the event synthesizing method in the IP signaling monitoring system under the GN interface.
Introduce the event synthesizing method in the IP signaling monitoring system under the GW interface below, as shown in Figure 2, comprising:
Step 201: GW interface IP signaling data are gathered.
Wherein, continue to carry out for the collection of signaling data, collection specifically how to carry out described data belongs to known technology, repeats no more here always.
Step 202: read a signaling of being gathered.
Step 203: judge the type of message of this signaling in HTTP, carry out respective handling according to the different messages type.
HTTP comprises three kinds of type of messages as shown in table 1:
| English name | Chinese |
| ??POST | Send |
| ??RESPONSE | Reply |
| ??NULL | Undefined |
Table 1
Same, when the multimedia message data amount is big, multimedia message data can be divided into 1500 message about byte and transmit when transmission, wherein, for the HTTP type, the form of embodiment is that a POST message is arranged earlier, and many NULL message are arranged subsequently, up to the multimedia message data end of transmission, when finishing RESPONSE message.
Because HTTP comprises above three kinds of type of messages, therefore, in this step, for the analysis of type of message among the HTTP, is divided into three kinds of situations equally:
If described signaling is a POST message, then set up GW TDR, and the MSISDN that obtains the user from x-up-calling-line-id is filled among the GW TDR according to characteristic value, afterwards, return execution in step 202, read next bar signaling of being gathered again.Wherein, the option that user MSISDN is obtained in configuration may be defined as x-up-calling-line-id, and described x-up-calling-line-id parameter is according to the different corresponding changes of actual set.
If described signaling is undefined message, then search GW TDR according to characteristic value, when finding corresponding GW TDR, the described signaling and the POST message combinations of GW TDR correspondence are in the same place, and relevant informations such as the receiving number of multimedia message in the described signaling, things sign (ID), multimedia message rank are filled into GW TDR, afterwards, return step 202, read next bar signaling of being gathered again.Concrete combination how to carry out POST message and NULL message belongs to known technology, repeats no more here.
If be RESPONSE message, then search GW TDR according to characteristic value, if find, then obtain event result, close GW TDR, show GW TDR end-of-fill, afterwards, return execution in step 202, read next bar signaling of being gathered again.
It more than is the event synthesizing method in the IP signaling monitoring system under the GW interface.
At present, by cell phone multimedia message swindle and the situation of the rate of escaping more and more, still, there still do not have to carry out under GN interface or the GW interface method that false transmitted number detects in the multimedia message to be open.

Embodiment
Basic thought of the present invention is: the transmission number and the MSISDN that obtain the user in the event synthesizing method under GN interface or GW interface, and described transmission number and MSISDN compared, determine according to comparative result whether user's transmission number is false transmitted number.
Below, be described with reference to the accompanying drawings the realization of the detection method of false transmitted number in the multimedia message of the present invention by specific embodiment.
Fig. 3 is the detection method schematic flow sheet of false transmitted number in the multimedia message under the GN interface of the present invention, and as shown in Figure 3, this method comprises:
Step 301～303: basic identical with step 101～103 shown in Figure 1, difference only is, when signaling is T-PDU, will continue execution in step 304.
Step 304: according to the purpose IP that comprises in the signaling, TEID composite character value, search GN TDR according to the characteristic value of being synthesized, if can find, then execution in step 305; Otherwise, return step 302, read next bar signaling of collection.
Step 305: judge that this signaling is that WAP type among the T-PDU still is the HTTP type, if be the WAP type, then execution in step 306; If be the HTTP type, then execution in step 307.
Step 306: judge the type of message of signaling on WTP layer and WSP layer.
At first, list the concrete type of message that WTP layer among the WAP and WSP layer are comprised, wherein, table 2 is depicted as the Chinese and English title contrast of the type of message that the WTP layer comprised:
| English name | Chinese |
| ??Invoke | Call |
| ??Segmented?Invoke | Burst calls |
| ??Result | The result |
Table 2
Table 3 is depicted as the Chinese and English title contrast of the type of message that the WSP layer comprised:
| English name | Chinese |
| ??POST | Send |
| ??REPLY | Reply |
Table 3
When the multimedia message data amount is big, multimedia message data can be divided into 1500 message about byte and transmit when transmission, wherein, for the WTP layer, the form that embodies is that an Invoke message is arranged earlier, many Segmented Invoke message are arranged subsequently, up to the multimedia message data end of transmission, are Result message when finishing.
According to above-mentioned listed WTP layer, the type of message that the WSP layer is comprised, as shown in Figure 3, the analysis for the WAP type of message in the step 306 comprises three kinds of situations:
The type of message of WTP layer is Invoke, when the type of message of WSP layer is POST, set up GI TDR according to characteristic value, and from the GN TDR of correspondence, obtain MSISDN and be filled among the GI TDR, when determining that this signaling content is multimedia message, execution in step 308 is when determining this signaling content not for multimedia message, return step 302, continue to read next bar signaling; Wherein, by the content of contentype parameter-definition signaling,, represent that the content in this signaling is multimedia message if when the contentype parameter is mms-message.
When the type of message of WTP layer is Segmented Invoke, search GI TDR according to characteristic value, when finding, relevant informations such as the receiving number of the multimedia message in the signaling, things ID, multimedia message rank are filled among the GI TDR, when determining that this signaling content is multimedia message, execution in step 308 is when determining this signaling content not for multimedia message, return step 302, continue to read next bar signaling.Wherein, when the type of message of the WTP of this signaling is Segmented Invoke, do not comprise the WSP layer in the signaling, therefore, do not have restriction for WSP layer type of message.
The type of message of WTP layer is Result, and the type of message of WSP layer is REPLY, searches GI TDR, obtains event result, closes GI TDR, shows GI TDR end-of-fill, afterwards, returns step 302, continues to read next bar signaling.
Wherein, in above-mentioned three kinds of situations, the pairing GN TDR of GI TDR is the GN TDR that signaling finds by characteristic value, owing to judge that the type of message that obtains described signaling is T-PDU, and in step 304, find the GN TDR of this signaling correspondence by characteristic value, thereby in this step, need not to search once more GN TDR, can with in the GI TDR of signaling correspondence and the step 304 search the corresponding GN TDR of signaling that obtains and associate.
In addition, specifically how to set up GI TDR, how to store and how to fill GI TDR etc. and all can use GN TDR of the prior art to set up, fill and storage means is finished, repeat no more here.
Described characteristic value is synthetic according to the relevant information in the signaling, synthetic method can for:
If source IP＞purpose IP, characteristic value is source IP+ purpose IP+ source port+destination interface; If source IP＜purpose IP, characteristic value is purpose IP+ source IP+ destination interface+source port.Because the IP address can change into number format when storage, the comparison of above-mentioned IP is finished between the value of the number format correspondence of institute's storing IP.
Step 307: judge the type of message of this signaling in HTTP, carry out respective handling according to the different messages type.
HTTP comprises three kinds of type of messages as shown in table 4:
| English name | Chinese |
| ??POST | Send |
| ??RESPONSE | Reply |
| ??NULL | Undefined |
Table 4
Same, when the multimedia message data amount is big, multimedia message data can be divided into 1500 message about byte and transmit when transmission, wherein, for the HTTP type, the form of embodiment is that a POST message is arranged earlier, and many NULL message are arranged subsequently, up to the multimedia message data end of transmission, when finishing RESPONSE message.
Because HTTP comprises above three kinds of type of messages, therefore, in this step, for the analysis of type of message among the HTTP, is divided into three kinds of situations equally:
If described signaling is a POST message, then set up GI TDR according to characteristic value, and from the GNTDR of correspondence, obtain MSISDN and be filled among the GI TDR, when determining that this signaling content is multimedia message, execution in step 308, when determining this signaling content, return step 302, continue to read next bar signaling not for multimedia message.
If described signaling is undefined message, then search GI TDR according to characteristic value, when finding corresponding GI TDR, the described signaling and the POST message combinations of GI TDR correspondence are in the same place, and relevant informations such as the receiving number of the multimedia message in the described signaling, things ID, multimedia message rank are filled into GI TDR, when determining that this signaling content is multimedia message, execution in step 308, when determining this signaling content, return step 302, continue to read next bar signaling not for multimedia message.Concrete combination how to carry out POST message and NULL message belongs to known technology, repeats no more here.
If be RESPONSE message, then search GI TDR according to characteristic value, if find, then obtain event result, close GI TDR, show GI TDR end-of-fill, afterwards, return step 302, continue to read next bar signaling.
Step 308: judge whether the signaling type of this signaling in MMSE is to send multimedia message, if, execution in step 309; Otherwise, return step 302, continue to read next bar signaling.
Wherein, the General Definition of the type of message among the MMSE is as shown in table 5:
| English name | Chinese |
| ??m-send-req | Send multimedia message |
| ??m-notifyresp-ind | Mms notification is replied |
| ??m-delivery-ind | Multimedia message sends successfully and replys |
| ??m-acknowledge-ind | Multimedia message receives successfully and replys |
