The method comprises the following steps that: a client splits a long-text short message into a plurality of messages and transmits a plurality of messages to a server, wherein a plurality of transmitted messages use the same short message service identifier, and each message comprises a message sequence number value of the message and the value of the total quantity of a plurality of messages; the server receives and caches a plurality of messages, and sets cache waiting time for receiving each message; the server verifies the quantity and sequence of the received messages which belong to the same short message service identifier with the value of the total quantity of the messages and the message sequence number value; the server adds a signature to the last message in a plurality of messages which can pass the verification; and the server forwards and processes the cached messages according to the message sequence number of the messages. By the method and the system, the problem that a bug exists when a message gateway adds a signature is solved.
Description
Technical field
The present invention relates to the network information security technology field, more specifically, relate to a kind of short message name signing method based on SMS gateway system and system.
Background technology
The refuse messages problem is day by day serious in recent years, is flooded with a large amount of advertisements in the note that the mobile subscriber receives every day, even the refuse messages of the content such as "pornography, gambling and drug abuse and trafficking"; Also having in addition the part offender to utilize short message channel to realize swindling, dispose of stolen goods etc. is the criminal activity of purpose, and people's normal life and safety is affected.
In order to administer refuse messages, each province and city Communications Administration Bureau requires mobile communication carrier that every profession and trade, the enterprise (EC/SI) that uses Short Message Service code (short message port) to send short message service carried out enterprise's real name signature management, real enterprise name is filled in and demonstrated to requirement in its short message content that sends to the cellphone subscriber, as " * * bank ", " * * company ", short message port generation secondary is subcontracted effectively to avoid, the subpackage phenomenon, avoid being utilized by the lawless person, also allow the user know the note source.
For this requirement, China Mobile's Carrier Requirements is realized the signature function of enterprise, industry note for enterprise, industry short message service access network element equipment-Industry Application Gateway system.And, for fear of continuity and the integrality formation impact of note signature on original short message content, become multiple messages to be sent to the situation of mobile phone terminal after splitting via EC/SI for ultralong short message, gateway only in the end a piece of news content back append enterprise's real name signature.Requiring of this note signature is as follows:
1, short message text signature function
Industry Application Gateway need to be supported the short message text signature function, in the MT flow process, SMS-A need to from IAGW-M return reply obtain information such as whether needing text signature and signature contents, if need the text signature, then SMS-A joins the back of the MT short message text of EC/SI submission to signature contents, and is handed down to the cellphone subscriber.
EC/SI needs oneself note to be split when submitting MT message to, and the note after supposing to split is N(N altogether 〉=1) bar, be Pk_total=N, front N-1 bar note can not added signature, and (be the last item, Pk_number=N) note can be coupled with signature to the N bar.
Above-mentioned information is taken from enterprise communication standard QB-D-038-2008 " Industry Application Gateway equipment code--the Duan Xin ﹠amp of China Mobile; WAP PUSH acts on behalf of fascicle V2.0.0 "
1.1 current mechanism and flow process:
Adopt following flow process to carry out the signature of message in the existing system;
1), enterprise, industry user (EC/SI) split into 1 or multiple messages with short message content to be sent according to length, every message content length＜160 byte or＜=140 bytes;
Note after the fractionation is N(N altogether 〉=1) bar message, so when EC/SI sends note, by Pk_total and the Pk_number field in the EC/SI setting CMPP_SUBMIT communications packets, wherein Pk_total extends this as the total number N that is split, Pk_number extends this as every message sequence number after the fractionation, this sequence number is since 1 take 1 as increment, pk_number=1 of article one message so, the pk_number=N of the last item message;
As: short message content to be sent is split as 3, and EC/SI need to arrange the Pk_total=3 in article one CMPP_SUBMIT bag, Pk_number=1 so;
Pk_total=3 in the second CMPP_SUBMIT bag, Pk_number=2;
Article three, the Pk_total=3 during (the last item) CMPP_SUBMIT wraps, Pk_number=3;
2) every message after, EC/SI will split is sent to the Industry Application Gateway system by the CMPP_SUBMIT communications packets;
3), the Industry Application Gateway system judges whether Pk_total equals Pk_number;
If equate, Industry Application Gateway will append enterprise's real name signature of this EC/SI in the content of message so, then this message is sent to short message service center, and message be sent to mobile phone terminal the most at last;
If not etc., Industry Application Gateway is directly with this message short-message center so, and message is sent to mobile phone terminal the most at last;
1.2 the problem that current mechanism and flow process exist:
Existing message forward process and signature mechanism: split into multiple messages for a ultralong short message by EC/SI and send situation, gateway system the many message after splitting is not carried out association and integrality is judged processing, but every message is received rear all by forwarding immediately; The message of the Pk_total=Pk_number that gateway system only sets for EC/SI is appended signature and is processed.Thus, EC/SI can be not equal to by the Pk_total that sets its every message the mode of Pk_number, makes its note do not appended enterprise's real name signature and successfully be sent to mobile phone terminal by gateway system.
For the leak that this mechanism exists, a typical flow process is as follows:
1), the short message content that sends of enterprise, industry user (EC/SI) is 200 bytes, need to split into 2 message and send;
Article one, message sets is: Pk_total=3, Pk_number=1;
The second message sets is: Pk_total=3, Pk_number=2;
2) 2 message after, EC/SI will split send the Industry Application Gateway system by the CMPP_SUBMIT communications packets;
3), the Industry Application Gateway system judges that Pk_total is not equal to Pk_number;
Industry Application Gateway is directly with this message short-message center, and message is sent to mobile phone terminal the most at last; These two message are not added enterprise's real name signature.
At present, the leak that some EC/SI utilize current mechanism to exist uses that its service number (short message port) is a large amount of to send the refuse messages that exceeds its scope of business, and its short message port is carried out secondary is subcontracted, subpackage; Cause some lawless person to utilize the unlawful activities such as this passage is swindled, multiple level marketing, bring serious potential safety hazard to the cellphone subscriber.

Embodiment
In the following description, for purposes of illustration, for the complete understanding to one or more embodiment is provided, many details have been set forth.Yet, clearly, can not have to realize these embodiment in the situation of these details yet.In other example, one or more embodiment for convenience of description, known structure and equipment illustrate with the form of block diagram.
Because the message forwarding mechanism of existing Industry Application Gateway system and signature treatment mechanism, there are the problem of omitting note signature in existing message forward process and signature mechanism.In order to address this problem, the present invention is directed to the note that is split into the overlength content of multiple messages transmission by EC/SI, adopt first buffer memory and multiple messages carried out signing after integrality association, the coupling again process and the method for forward process, to avoid the leak problem of note signature.
Below with reference to accompanying drawing specific embodiments of the invention are described in detail.
Fig. 1 shows the flow chart according to the short message name signing method of the embodiment of the invention.
As shown in Figure 1, short message name signing method provided by the invention comprises the steps:
S110: client splits into multiple messages with this note of long article by its text size, and send described multiple messages to server end, the multiple messages that sends uses same short message service sign, and every message in the multiple messages all comprises the numerical value of the message total amount of the numerical value of message sequence number of this message and multiple messages;
S120: server end receives and the above-mentioned multiple messages of buffer memory, and sets the buffer memory stand-by period of every message;
S130: server end buffer memory in the stand-by period to belonging to of receiving described same short message service sign message number and the numerical value of sequence and above-mentioned message total amount and the numerical value of message sequence number carry out verification, if the message number of receiving equates with the numerical value of message total amount, and every message sequence number of multiple messages is to be incremented to the numerical value of described message total amount since 1 take 1 as the increment order, and then be regarded as can be by the message of this verification for multiple messages;
S140: server end is to appending signature by the last item message in the multiple messages of above-mentioned verification;
S150: server end is according to the multiple messages of the message sequence number forward process buffer memory of multiple messages.
Can find out according to above flow process, short message name signing method provided by the invention relates to the multiple messages that sends after EC/SI splits long SMS (that is: PK_OTAL〉1 message) for all and carries out first message buffering, do not transmit, and setup message is in the intrasystem buffer memory stand-by period; At buffer memory in the stand-by period, gateway is received other the message of EC/SI after sending to this cellphone subscriber and splitting successively, and is the message sequence number to the message count numberical value of quantity that belongs to the same long SMS and the sequence of receiving with quantity (being the message total amount) and the pk_number(that pk_total sets) numerical value carry out integrality and correctness is mated verification; If the message number after the fractionation that gateway is received equals the numerical value that EC/SI sets pk_total, and the pk_number of multiple messages is incremented to pk_total since 1 take 1 as the increment order, appends so enterprise's real name signature in the message content of pk_number=pk_total.Then these message are carried out follow-up forward process.
For the situation of long SMS buffer memory, coupling anomaly association in Short Message Service Gateway, can ensure by the mode of setting the optional mechanism of timeout treatment the flexibility of note signature.
Particularly, when arriving or surpassing buffer memory during the stand-by period, send to the pk_total quantity that message number＜EC/SI sets after this cellphone subscriber splits if gateway is received EC/SI, so, can adopt the following two kinds of processing modes that can select:
Refuse forward process for the message of buffer memory, to the status report of EC/SI return messages retransmission failure, it is imperfect and lead to the failure that the error code in the status report identifies the message that issues;
Append signature at pk_number and pk_total near message content, then the multiple messages of receiving is carried out follow-up forward process.
Above-mentioned store-and-forward mechanism and signature processing method can solve EC/SI and fill in the note signature leak problem that PK_TOTAL, PK_NUMBER bring not according to rule.But, in actual mechanical process, also exist same EC/SI at short notice (the buffer memory stand-by period of default in) send the note situation that 2 of different content or a plurality of needs are split to a user, for example:
EC/SI need to send respectively the note that the needs of two different contents are split to same user; Content 1 is " your bank save XXXX.... ", and content-length is 240 bytes (surpassing 160 bytes), need to be split into 2 message and send; Another content 2 also needs to be split into 2 message and sends for " the XXXX security current market value XXXX.... that you use " content-length is 200 bytes (surpassing 160 bytes).
In the above-mentioned situation, which ultralong short message is the message that the PK_TOTAL that only sets according to EC/SI and PK_NUMBER can't differentiate after the fractionation of receiving from EC/SI belong to.Therefore, in the present invention, identify to confirm that with same short message service the multiple messages that splits transmission belongs to same short message service sign.That is to say, set a unique short message service sign by EC/SI according to short message content, send if this note content overlength need to be split into multiple messages, so, the message after these split is used same short message service sign.
The below is different take note access criteria CMPP2.0 agreement short message name signing method provided by the invention and existing message forward process and signature mechanism as example further describes.
Former CMPP_SUBMIT message definition (SP → ISMG) as shown in table 1 below:
The former CMPP_SUBMIT message of table 1 bag table
Amended CMPP_SUBMIT message definition (SP → ISMG) as shown in table 2 below:
The amended CMPP_SUBMIT message of table 2 bag
Fig. 2 shows in the information interaction flow process between EC/SI, Short Message Service Gateway, sms center and the portable terminal under existing message forward process and the signature mechanism.
As shown in Figure 2, be 120 Chinese characters as the content of short message of example, i.e. 240 bytes: " distinguished client XXXX ... it is complete to transfer accounts uses if continue ... thank and use! ".According to existing message forward process and signature mechanism, need to be to certain mobile terminal to send message content during greater than 140 bytes as EC/SI, the information interaction flow process between EC/SI, Short Message Service Gateway, sms center and the portable terminal is as follows:
S210:EC/SI judges that message surpasses protocol specification length (140 bytes), message need to be split as N bar note and send; N is 2 in this example, is respectively:
Article 1, content: distinguished client XXXX ... it is complete to transfer accounts, and 1/2
N(2) bar content: use if continue ... thank and use! 2/2
S220:EC/SI forms CMPP_SUBMIT message bag with article one content and is sent to Short Message Service Gateway:
PK_TOTAL=N；
PK_NUMBER=1；
S221: the message bag that Short Message Service Gateway sends according to EC/SI, judge that PK_TOTAL is not equal to PK_NUMBER, behind this short message content, do not append signature;
S222: Short Message Service Gateway is forwarded to next network element (sms center) with this message;
S223: this message is forwarded to portable terminal by sms center;
S224: portable terminal is received article one message, and displaying contents: distinguished client XXXX ... it is complete to transfer accounts, and 1/2;
S230: after step S220, EC/SI continues N(2) the bar content forms CMPP-SUBMIT message bag and is sent to Short Message Service Gateway:
PK_TOTAL=N（2）；
PK_NUMBER=2；
S231: the message bag that Short Message Service Gateway sends according to EC/SI, judge that PK_TOTAL equals PK_NUMBER, behind this short message content, append signature [XX bank];
S232: Short Message Service Gateway is forwarded to next network element (sms center) with this message;
S233: this message is forwarded to portable terminal by sms center;
S234: portable terminal is received N(2) bar message, and displaying contents: use if continue ... thank and use! 2/2[XX bank];
Shown in Figure 2 is that an EC/SI fills in the note signature that PK_TOTAL, PK_NUMBER bring according to correct rule, and through normal message forwarding process, the last item note that portable terminal is received is added signature.But under abnormal conditions, if EC/SI fills in PK_TOTAL, PK_NUMBER not according to correct rule, the last item note that then can exist portable terminal to receive is not added the possibility of signature.
Such as, in existing Short Message Service Gateway note signature handling process schematic diagram shown in Figure 3, EC/SI is split as 2 notes with message and sends, and is respectively:
Article 1, content: distinguished client XXXX ... it is complete to transfer accounts, and 1/2
Article one content is formed CMPP_SUBMIT message bag is sent to Short Message Service Gateway:
PK_TOTAL=2；
PK_NUMBER=1；
The 2nd content formed CMPP_SUBMIT message bag is sent to Short Message Service Gateway:
PK_TOTAL=2；
PK_NUMBER=1；
Like this, gateway does not all append signature through judging behind two short message contents, thereby the last item note that causes being passed to portable terminal is not added signature, has evaded the requirement of mobile communication carrier for note signature.
And adopt short message name signing method provided by the invention, then can effectively avoid the signature leak problem under the above-mentioned abnormal conditions.
Fig. 4 and Fig. 5 show respectively according to the note signature normal process flow process of the embodiment of the invention and abnormality processing flow process.
As shown in Figure 4, need to be to certain mobile terminal to send message content during greater than 140 bytes as EC/SI, the normal information interaction flow between EC/SI, Short Message Service Gateway, sms center and the portable terminal is as follows:
S410:EC/SI judges that message surpasses protocol specification length (140 bytes), message need to be split as N bar note and send; N is 2 in this example, is respectively:
Article 1, content: distinguished client XXXX ... it is complete to transfer accounts, and 1/2
N(2) bar content: use if continue ... thank and use! 2/2
S420:EC/SI forms CMPP_SUBMIT message bag with article one content and is sent to Short Message Service Gateway:
PK_TOTAL=N；
PK_NUMBER=1；
MSG_SEQ=YYYYYYY
S421: Short Message Service Gateway judge PK_TOTAL greater than 1 and PK_NUMBER be not equal to PK_TOTAL, the buffered message quantity of searching MSG_SEQ=YYYYYYY is 0;
S422: this message of Short Message Service Gateway buffer memory, wouldn't send, wait for remaining N-1 bar message, and set the buffer memory stand-by period;
S430: after step S420, EC/SI continues N(2) the bar content forms CMPP-SUBMIT message bag and is sent to Short Message Service Gateway:
PK_TOTAL=N(2)；
PK_NUMBER=2；
MSG_SEQ=YYYYYYY
S431: Short Message Service Gateway judge PK_TOTAL greater than 1 and PK_NUMBER equal PK_TOTAL, the buffered message quantity of searching MSG_SEQ=YYYYYYY is 1;
S432: Short Message Service Gateway judges and to have received that the message number N (2) of MSG_SEQ=YYYYYYY equates with the quantity N (2) of PK_TOTAL, equals at PK_NUMBER to append signature [XX bank] behind the short message content of PK_TOTAL;
S433: Short Message Service Gateway is forwarded to next network element (sms center) with N (2) bar message according to sequencing;
S434:N (2) bar message is forwarded to portable terminal by sms center;
S435: portable terminal is received article one short message, and displaying contents: distinguished client XXXX ... it is complete to transfer accounts, and 1/2;
S436: portable terminal is received N(2) the bar short message, and displaying contents: use if continue ... thank and use! 2/2[XX bank];
And for the processing of abnormal conditions, as shown in Figure 5, if EC/SI is split as N bar note with message and sends; N should be 2 in this example, but EC/SI is set as 3 with N, and the message content after actual the fractionation is respectively:
Article 1, content: distinguished client XXXX ... it is complete to transfer accounts, and 1/2
For these two contents, PK_TOTAL=N (3) in the CMPP_SUBMIT message bag of its composition, therefore, when the message that these two contents form is coated be sent to Short Message Service Gateway after, because the message number of MSG_SEQ=YYYYYYY is less than the value of PK_TOTAL, so the equal buffer memory of Short Message Service Gateway, wouldn't send.Yet the in fact not existence of the 3rd content, so Short Message Service Gateway can be waited for to the buffer memory stand-by period always and arriving, then adopt following 2 to select 1 processing:
S533-1: refuse forward process for the message of buffer memory, to the status report of EC/SI return messages retransmission failure, the error code in the status report identifies owing to the message that issues is imperfect and leads to the failure;
S533-2: append signature in or the message content received at last the most approaching at PK_UMBER and PK_TOTAL, then the multiple messages with institute's buffer memory carries out follow-up forward process.
Under the processing mode of S533-2, gateway is forwarded to next network element (sms center) with N (2) bar message according to sequencing, and then successively is forwarded to portable terminal.Like this, even EC/SI does not fill in PK_TOTAL according to correct rule, the last item note that portable terminal is received also can be added signature, has avoided Short Message Service Gateway to append the omission problem of signature.
Fig. 6 shows the logical construction block diagram according to the note signature system of the embodiment of the invention.
As shown in Figure 6, the note signature system comprises client 500 and server end 600, wherein, client 500 splits into multiple messages with this note of long article by its text size, and send described multiple messages to server end, the multiple messages that sends uses same short message service sign, and every message in the multiple messages all comprises the numerical value of the message total amount of the numerical value of message sequence number of this message and multiple messages, and server end 600 comprises message sink unit 610, message verification unit 620, signature unit 630 and retransmission unit 640.Wherein, message sink unit 610 is used for receiving and slow being deposited splits the multiple messages that sends, and sets the buffer memory stand-by period of every message; Message verification unit 620 is used in the stand-by period message number that belongs to same short message service sign received and the numerical value of sequence and message total amount and the numerical value of message sequence number being carried out verification at buffer memory; Wherein, if the message number of receiving equates with the numerical value of message total amount, and every message sequence number of multiple messages is to be incremented to the numerical value of described message total amount since 1 take 1 as the increment order, and then be regarded as can be by the message of described verification for described multiple messages; Signature unit 630 is used for the last item message of multiple messages that can be by described verification is appended signature; The multiple messages that retransmission unit 640 is used for according to the described buffer memory of message sequence number forward process of described multiple messages.
In addition, the omission of the note signature that when EC/SI fills in PK_TOTAL, PK_NUMBER not according to correct rule, causes, note signature system 600 also comprises exception processing unit 650, be used for arriving or surpassing described buffer memory during the stand-by period, if the described message number of receiving is less than default message total amount, then: refusal is transmitted the multiple messages of described buffer memory; Perhaps, append note signature in the message content close to the numerical value of described default message total amount at the numerical value of described message sequence number, then the multiple messages with described buffer memory carries out forward process.
In addition, the present invention also provides a kind of SMS gateway system that comprises the said short message signature system, split many notes after information splits it with the note of setting according to transmit leg (EC/SI) and carry out buffer memory, combination and matching treatment and judge which bar short message content is the mode of ultralong short message integrality be chosen in and append note signature, effectively avoid Short Message Service Gateway to append the leak problem of signature.
The present invention also is applicable to system and agreement that other have the ultralong short message signature to process except being used for SMS gateway system and CMPP2.0 agreement.
