Step S10, service control node SCP receive the short message that short message sender sends, and return to short message sender
Complex response message；
The received short message types of SCP be SMDPP (Short Message Delivery Peer To Peer) or
After SMSREQ (Short Message Service Request), SCP receive the short message that short message sender sends,
Response message is replied to short message sender.
Step S20, SCP parse the short message, and the message content of the short message obtained according to parsing determines whether
The short message is sent to short message receiving debit；
SCP parses the short message that receives, and the content parsed includes numbers of calling and called parties, short message content, Number Authority etc.,
And determine whether to send the short message to short message receiving debit according to the message content of the short message that parsing obtains, for example,
It rises and is exhaled in MO (Mobile Originated) process in short message, judge whether this short message is sent to mobile phone outside group
On, if there is the outer permission sent short messages of net.
Step S30, when determine send short message to short message receiving debit when, the short message to short message is received
Side.
When IVPN user is sent short messages successfully by IVPN platform, short message can be generated on SCP and sends record information,
CDR file is generated, for recording relevant to short message information, such as short message number of words, number of short etc..SCP can be with
Classification naming is carried out to CDR file is generated using a new business key, to distinguish calling ticket and short message ticket.
The major way that telecom operators use at present is uniformly controlled by MC (Message Center, sms center)
The transmitting-receiving of short message.Its main feature is that covering orientation is wide, amphicheirality, economy, caching capabilities, but MC control has departing from IVPN user
Some group's attributes simply control the transmitting-receiving of its short message.Fig. 1 is the network structure centered on MC.Therefore, it is necessary to by short message
The permission of transmitting-receiving is put on SCP, short message receiving-transmitting is realized by SCP not only, the function of MC transmitting-receiving short message may be implemented, additionally it is possible to is quasi-
The true group's attribute having according to user receives and dispatches short message, really accomplishes the calling that user is uniformly controlled by SCP and short
Letter transmitting-receiving.For example, calling subscriber can only send short message to group internal user, and MC is unable to control the transmitting-receiving of this short message, because
Called subscriber and calling subscriber can not be known whether in the same group for MC；IVPN user is allowed to send before the deadline
Short message, MC can not also judge whether allow to send short message at this time, because the time data of setting are on SCP.Fig. 2 is controlled by MC
The short message receiving-transmitting process of system.Since the function of IVPN business is various, the function MC of many short message receiving-transmitting controls be cannot achieve, because
This must be controlled by SCP.
In the present embodiment, the short message that short message sender sends is received by SCP, parses the short message, and root
The message content of the short message obtained according to parsing determines whether to send the short message to short message receiving debit, realizes operation
The SCP of IVPN platform realizes the transmitting-receiving of short message, and the receipts of short message can not be controlled according to group's attribute of IVPN user by solving MC
Hair, the problem of having a single function of MC short message receiving-transmitting control, is better achieved the transmission that calling and short message are uniformly controlled on SCP,
Facilitate management, overall cost is low, can more effectively support the popularization and development of IVPN business, and the development for being more in line with industry becomes
Gesture.
Further, referring to Fig. 4, in the method second embodiment of IVPN platform sending and receiving short messages of the present invention, step S10
Before, the method for the IVPN platform sending and receiving short messages further include:
Step S01, SCP increase the mobile application section MAP signaling manipulation for supporting SMDPP, for when in short message original
Point-to-point short message transmission is realized when exhaling MO process；
Step S02, SCP increase the MAP signaling manipulation for supporting SMSREQ, for obtaining when being in SMS terminal call MT process
Take the routing iinformation of current mobile station MS.
While the signaling manipulation of SMDPP and SMSREQ is supported in SCP addition, the table on IVPN platform is modified, due to user
Essential information all has existed in table sxxcardinf, realizes that the table of IVPN user function also all has existed, so only needing
Short message receiving-transmitting control can be realized by increasing the related necessary table of several short messages.
Increase the mapping table that table sxxmcgt is used to the signaling address GT of memory mobile phone number section and sms center, short message
When MO process, firstly, reading relevant information from user's table sxxcardinf and group table sxxgroupinf whether to judge user
The transmission for carrying out short message is had permission, again, inquiry table sxxmcgt obtains the corresponding MC's of mobile phone number section if allowing to send
GT, finally, short message is delivered to MC by SMDPP informational message.
Further, referring to Fig. 5, Fig. 9 and Figure 10, in the method 3rd embodiment of IVPN platform sending and receiving short messages of the present invention
In, step S10 includes:
Step S101, when being in short message MO process, SCP receives the SMDPP message that moving exchanging center MSC is sent,
And SMDPP message is returned to MSC；The SMDPP message is MSC after receiving MS and sending short message by air interface, will
The short message conversion is sent out by SMDPP message and according to for the international mobile subscriber identity IMSI of the SMDPP message arrangement
It send；
When being in short message MO process, MS sends short message, sends short message to MSC by air interface, MSC will be empty
The short message conversion that middle interface is sent is SMDPP message.It wherein include numbers of calling and called parties, short message content, short message in SMDPP message
The contents such as coding mode.Then some specified IMSI sections are pre-allocated, SMDPP message is transmitted directly to by MSC according to IMSI number
SCP.SCP receives the SMDPP message that MSC is sent, and SMDPP is sent to MSC by SCP, it was demonstrated that has received short message.If there is number
It also include the data for needing to return in the SMDPP of return according to return.The SMDPP message that SCP is sended over is received in MSC
When, SMDPP is converted to the confirmation message of air interface by MSC.
Step S102, when being in short message MT process, SCP receives the Deliver_SM message that sms center MC is sent,
And Deliver_SM_Res message is replied to MC.
When being in short message MT process, Deliver_SM message is sent directly to IVPN platform by MC, i.e. on SCP；SCP
Deliver_SM_Res message is replied at once to MC, and informing has received message.
Further, referring to Fig. 6, Fig. 9 and Figure 10, in the method fourth embodiment of IVPN platform sending and receiving short messages of the present invention
Middle step S20 includes:
Step S201, when being in short message MO process, SCP parses received SMDPP message；
Step S202, SCP determine whether to send short message according to the SMDPP message content that parsing obtains；
SCP parses the SMDPP message received, and the numbers of calling and called parties parsed, short message content etc. are sent into Business Stream
Journey processing center is handled, for example, judging whether the transmission of this short message is sent to outside group on mobile phone, if there is past outgoing
Send the permission etc. of short message.
Step S2021, if so, SMDPP message is sent to MC by SCP, so that MC issues the SMDPP message to called MS
(Mobile Station, mobile station)；
If the judgement of operation flow module is to send short message, SCP is by the important informations group packet such as numbers of calling and called parties, short message content
It is sent to MC at SMDPP message, the short message that MS is originally sent by MC is issued on the mobile phone of called subscriber.
Step S2022, if it is not, SCP call release, terminates short message MO process.
If the judgement of operation flow module is not send short message, the direct call release Release Call of SCP, refusal
The transmission of short message.
Step S203, when being in short message MT process, SCP parses received Deliver_SM message；
When being in short message MT process, Deliver_SM message is sent directly on SCP by MC, and SCP is replied at once
Deliver_SM_Res message has received message to MC, informing.
Step S204, SCP determine whether to send short message according to the parsing content of Deliver_SM message；
SCP parses the Deliver_SM message received, and the relevant informations such as numbers of calling and called parties are sent into operation flow
Processing center judges whether that short message can be sent.
Step S2041, if not sending short message, SCP call release terminates short message MT process；
Step S2042 sends short message if judgement, and SCP sends SMSREQ and disappear according to the called number in message content
Breath inquires the current MSC location information of called number to home location register HLR；
Step S2043, when the SMSREQ response message that HLR is returned has the current MSC address information of called number, SCP
Called number current MSC address information is recorded, the SMDPP message MSC current to called number is sent, so that MSC disappears SMDPP
Breath is forwarded to called MS；
Succeed if SCP sends SMDPP message to current MSC is called, SCP will receive the response of the SMDPP of MSC transmission
Message；If response message is successfully SCP status report to MC, inform that MC short message is sent successfully, SCP receives MC really
Recognize message, learns that MC is properly received state report, SCP terminates entire MT process；If response message is failure, SCP is by main quilt
It is saved in the table sxxsmsfail of the relevant informations such as code, short message content of calling out the numbers write-in database, this table of timing scan comes again
It sends SMSREQ message to be inquired to HLR, retransmits SMDPP message later to MSC.
In view of the performance of SCP, the time of scan table sxxsmsfail can be configured, such as be scanned every 5 minutes
Once.Every in table record all having times stab field, if it exceeds 2 days (can configure), then delete this information, no longer into
The subsequent processing of row.If SCP successfully sends this information after scanning certain record, then mark position is indicated for ' 1 '
It is sent successfully, is not needed to scan this and have recorded.
Step S2044, when the SMSREQ response message that HLR is returned does not have the current MSC address information of called number,
SCP timing retransmits SMSREQ message to HLR.
When sending SMSREQ message, does not inquire called routing iinformation or HLR is not responded to, such as called shutdown,
Called no longer service area etc., SCP will be in the table sxxsmsfail of the relevant informations such as numbers of calling and called parties, short message content write-in database
It saves, this table of timing scan is inquired to retransmit SMSREQ message to HLR.
In order to achieve the above object, the present invention also provides a kind of service control node SCP, referring to Fig. 7, in SCP of the invention the
In one embodiment, SCP includes:
Receiving module 40 replys response to short message sender and disappears for receiving the short message of short message sender transmission
Breath；
The received short message types of receiving module 40 are SMDPP (Short Message Delivery Peer To
Peer) or SMSREQ (Short Message Service Request), receiving module 40 receive short message sender hair
After the short message sent, response message is replied to short message sender.
Analysis judgment module 50, for parsing the short message, according to the message content for the short message that parsing obtains
Determine whether to send the short message to short message receiving debit；
Analysis judgment module 50 parses the short message that receives, the content parsed include numbers of calling and called parties, short message content,
Number Authority etc., and the message content of the short message obtained according to parsing determines whether to send the short message to short message receiving
Debit exhales in MO (Mobile Originated) process for example, rising in short message, judges whether this short message is sent to collection
On the outer mobile phone of group, if having the outer permission sent short messages of net.
Sending module 60, for when determine send short message to short message receiving debit when, by the short message to short
Message receiver.
When IVPN user is sent short messages successfully by IVPN platform, short message can be generated on SCP and sends record information,
CDR file is generated, for recording relevant to short message information, such as short message number of words, number of short etc..SCP can be with
Classification naming is carried out to CDR file is generated using a new business key, to distinguish calling ticket and short message ticket.
In the prior art, the major way that telecom operators use at present is by MC (Message Center, in short message
The heart) it is uniformly controlled the transmitting-receiving of short message.Its main feature is that covering orientation is wide, amphicheirality, economy, caching capabilities, but MC control is de-
The group's attribute having from IVPN user simply controls the transmitting-receiving of its short message.Fig. 1 is the network structure centered on MC.Cause

MS；
Succeed if SCP sends SMDPP message to current MSC is called, SCP will receive the response of the SMDPP of MSC transmission
Message；If response message is successfully SCP status report to MC, inform that MC short message is sent successfully, SCP receives MC really
Recognize message, learns that MC is properly received state report, SCP terminates entire MT process；If response message is failure, SCP is by main quilt
It is saved in the table sxxsmsfail of the relevant informations such as code, short message content of calling out the numbers write-in database, this table of timing scan comes again
It sends SMSREQ message to be inquired to HLR, retransmits SMDPP message later to MSC.
In view of the performance of SCP, the time of scan table sxxsmsfail can be configured, such as be scanned every 5 minutes
Once.Every in table record all having times stab field, if it exceeds 2 days (can configure), then delete this information, no longer into
The subsequent processing of row.If SCP successfully sends this information after scanning certain record, then mark position is indicated for ' 1 '
It is sent successfully, is not needed to scan this and have recorded.
When the SMSREQ response message that HLR is returned does not have the current MSC address information of called number, timing is sent out again
Send SMSREQ message to HLR.
When sending SMSREQ message, does not inquire called routing iinformation or HLR is not responded to, such as called shutdown,
Called no longer service area etc., SCP will be in the table sxxsmsfail of the relevant informations such as numbers of calling and called parties, short message content write-in database
It saves, this table of timing scan is inquired to retransmit SMSREQ message to HLR.
It establishes and supports long SMS transmission, more sms centers, currently, MC is more than 160 English words for message content length
The short message of symbol or 70 Chinese characters, being divided into a plurality of continuous short message automatically, (every contains 153 English characters or 66 Chinese
Word, most 255) it is continuously transmitted by a plurality of mode.When such as short message MT process, long SMS can be split by MC, every short message
Head all add UDHI (User Data Header Indicator) and be used to indicate it is same short message, SCP has receiving
When the short message on the identical head UDHI, these short messages can be assembled into a complete short message.Last business logic modules are sentenced
Break to decide whether to send this short message.
If there are two MC, if first short message is from MC1, Article 2 short message is from MC2, then SCP is issuing MC
When state report, it must just accomplish to be sent to correct MC up.In MT process, SCP is in the Deliver_ for receiving MC transmission
When SM message, SCP can be according to one value SmppSktIndex_T of this Message Record, for indicating that Deliver_SM message comes from
MC1, SmppSktIndex_T correspond to the account and address port of Deliver_SM message, send Submit_SM shape in SCP in this way
When state is reported to MC, corresponding message can be found according to SmppSktIndex_T should be sent to MC up.
The above is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills
Art field, is included within the scope of the present invention.
