Abstract
The present invention provides a short message forward shifting realizing method which has the key that SMC obtains a route response according to a returned short message of HLR or determines whether a received short message is forward shifted according to the short message forward shifting information which is preserved by the self of the SMC. The SMC can send the forward shifted short message to the user again according to the requirement of the user or a user who enrolls to forward shift is notified that the forward shifting short message is successfully sent to the forward shifting user. Even a called party and the forward shifting user are not under the same PLMN, the short message can also realize to forward shift by using the present invention, and the method can become a competition measure to attract users for different operators. Because only the SMC needs to be carried out software update or the HLR and the SMC are carried out software update at the same time, the present invention can be realized. Consequently, the present invention has better practicability.
Description
Technical field
The present invention relates to the short message communication technical field, be meant a kind of method that realizes Short Message Service Call forwarding especially.
Background technology
Short message has non real-time feature as a kind of point-to-point communication mode, all depends on signaling method and realizes, does not take user's face resource, and is cheaply many with respect to the audio call charge, receives liking of operator and user greatly.
Can realize in broadband CDMA/global system for mobile communications (WCDMA/GSM) system at present: mobile originating short message and Mobile-Terminated Short Message.
Though the user can determine the short message of mobile phone terminal stored is sent to other user again, this forwarding operation is artificial, rather than the automatic forwarding operation of network intelligence.
Because the flow process that realize short message in circuit switching (CS) territory and packet switching (PS) territory is similar substantially, be that example describes only below therefore with the CS territory.
Figure 1 shows that the schematic flow sheet of the realization Short Message Service Call forwarding of prior art.Under this implementation, suppose that the calling subscriber is a, the Mobile Subscriber International ISDN number of user a (MSISDN) is this calling subscriber's address, note is made MSISDNa, the called subscriber is b, called address is the MSISDN of user b, note is made MSISDNb, called subscriber b is designated international mobile subscriber identity (IMSI), note is made IMSIb, and the forwarding subscriber that the called subscriber contracted is c, and the address note of forwarding subscriber c is made MSISDNc, the sign note of forwarding subscriber c is made IMSIc, and flow chart shown in Figure 1 may further comprise the steps:
Step 101, after short message service center (SMC) receives short message from calling subscriber a, issue portable terminal termination (MT) short message to short message service/GMSC (gateway mobile switching center) (SMS-GMSC), carry calling address MSISDNa in this MT short message, called address MSISDNb and content of short message SMSa-b etc.;
Step 102, SMS-GMSC follows according to short message called address MSISDNb, judges whether the called subscriber is current Public Land Mobile Nerwork (PLMN) user, if then the attaching position register under called subscriber b (HLR) is initiated the short message route requests; Otherwise SMS-GMSC sends to the SMS-GMSC of the PLMN under the MSISDNb to current short message, is initiated to comprise the short message route requests of MSISDNb information by the HLR of SMS-GMSC under user b at MSISDNb place;
Step 103, after HLR receives the short message route requests, judge at first whether this MSISDNb has registered forward-shifting service, if not, then return the number (MSC-Number) of the mobile switching centre that comprises the current place of user b and the short message of IMSIb and get route response (RoutingInfoForSM-Res), execution in step 104 then; If HLR judge MSISDNb registered forward-shifting service, and current being in of forwarding subscriber c adhere to (Attached) state, then returns the MSC-Number that comprises the current place of forwarding subscriber c and the RoutingInfoForSM-Res of IMSIc;
Step 104, SMS-GMSC issues the MT short message according to the information that HLR returns to the MSC at user b or user c place;
Step 105～step 107, MSC gives the MT short message issuing according to the information that obtains the portable terminal (UE/MS) of user b or user c, and the response message of success that sends according to the UE/MS of user b or user c or the failure response message that returns success or fail to SMS-GMSC, the response message that returns success or fail to SMC by SMS-GMSC.
The short message of the above-mentioned user of sending to b is common short message, sends to the preceding short message that changes of being of user c.
In the above-mentioned process that sends SMS message, if current separation (Detached) state that is in of user b is then waited until after its position is upgraded to send before the deadline again.What is called waits until that the process that sends again after its position is upgraded is: SMC obtains notification message (the Alert SC from HLR, SC is SMC) after, sending SMS message to corresponding HLR once more sends routing information, and at this moment, HLR returns the short message that comprises MSC-Number and IMSI to SMC and gets route response.
There is following defective in above-mentioned implementation:
1) called subscriber and forwarding subscriber are that user b and user c must be in PLMN networks, otherwise can't realize Short Message Service Call forwarding, and this is that the HLR at user b place can't obtain the MSC-Number and the IMSIc at user c current roaming place because under different PLMN;
2) user b can't learn that the Short Message Service Call forwarding which should send to oneself given the user c, has forwarded user c to before also can't knowing whether;
3) for user c, may there be certain doubt in the short message from user a that it is received, because user c may not know that this is the short message that transfers before the user b;
4) charging control is inconvenient, owing to be that SMC produces the short message ticket, but SMC does not know to change before the short message generation, when producing ticket, can't charge so for called subscriber's preceding commentaries on classics short message, therefore, can only charge to the called subscriber with the form of monthly rent in the operation, and can not charge by number of times.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of method that realizes Short Message Service Call forwarding, makes called subscriber and forwarding subscriber also can not realize preceding commentaries on classics under same PLMN.

Figure 2 shows that the schematic flow sheet of the realization Short Message Service Call forwarding of using one embodiment of the invention.
Embodiment
Again the present invention is done detailed description further below in conjunction with accompanying drawing.
Thinking of the present invention is: the information of being returned according to HLR by SMC or determine whether that according to the Redirection Information of self preserving the short message that will receive carries out preceding commentaries on classics, and according to user's needs, SMC the short message that changes before can be sent to again this user and or notification enrollment before change short message before the user that changes and successfully send to forwarding subscriber.
Existing SMC has the ability of SMS-GMSC usually, can initiate short message to HLR and send routing information, and therefore, the SMC that following the present invention mentioned is the SMC with ability of SMS-GMSC.
The Short Message Service Call forwarding mode of user registration has following two kinds: a kind of is Call Forwarding Unconditional (CFU-SMS) mode, and promptly all short messages of issuing this user forward to before all on the forwarding subscriber that this user registers; A kind of is (CFD-SMS) mode of changeing before the released state, promptly have only when this user is current when being in separation (Detached) state, just the Short Message Service Call forwarding that will issue this user is to the forwarding subscriber that this user registered, as long as the current attachment state that is in of this user changes operation before then not carrying out.No matter this user registers commentaries on classics mode before which kind of, and whether this user can also register and still send SMS message to self and or notify self information during the commentaries on classics short message forwarding subscriber is successfully received before.
When HLR receives short message from SMC when sending routing information request, do not change before the registration if detect the called subscriber, then HLR returns the short message that comprises IMSI and positional information (locationInfo WithLMSI) to SMC and gets route response.If detect the called subscriber registered Short Message Service Call forwarding information, then do respective handling according to the information of being registered.
Figure 2 shows that the schematic flow sheet of the realization Short Message Service Call forwarding of using one embodiment of the invention.In the present embodiment, suppose that the calling subscriber is a, the Mobile Subscriber International ISDN number of user a (MSISDN) is this calling subscriber's address, note is made MSISDNa, and the called subscriber is b, and called address is the MSISDN of user b, note is made MSISDNb, the sign IMSI of called subscriber b, and note is made IMSIb.Called subscriber b registers Redirection Information in HLR, the forwarding subscriber of being registered is c, and the address of this forwarding subscriber c is the MSISDN of user c, and note is made MSISDNc, the sign IMSI of forwarding subscriber c, and note is made IMSIc.
In the present embodiment, suppose that the Short Message Service Call forwarding information that user b is registered is: commentaries on classics mode before the released state, the MSISDNc of forwarding subscriber c still sends SMS message to self, notify the information of self when changeing short message before successfully receiving with forwarding subscriber c, and the current released state that is in of user b.
Flow chart shown in Figure 2 may further comprise the steps:
Step 201, after SMC received short message from calling subscriber a, the request of sending routing information that sends SMS message of the HLR under MSISDNb below was made HLRb with the note of the HLR under the MSISDNb.
Step 202, if user b changes but current being in when adhering to (Attached) state before only having registered Detached, MSC-Number that this HLRb directly returns for SMC to comprise user b place and the short message of IMSIb are got route response (RoutingInfoForSM-Res), otherwise, the Short Message Service Call forwarding information that HLRb is registered according to called subscriber b is returned correspondingly information to SMC.Based on the assumed condition of present embodiment, HLRb returns the MSISDNc that comprises forwarding subscriber c, sends short messages to and change short message before called subscriber (DeliverSMSToSubscriber) sign and the advise called subscriber and send successfully the short message that (NotifySubscriberForwardSMSSuccess) indicate and get route response to SMC.
Step 203～step 205, SMC parse in the RoutingInfoForSM-Res of HLRb comprise DeliverSMSToSubscriber sign after, current short message is duplicated portion, currently like this in SMC, there are two parts of short messages that content is identical: the calling subscriber a of a copy of it, the called subscriber is b, note is made SMSa-b, comprises MSISDNa among this SMSa-b, MSISDNb and content (Content).Because the current released state that is in of user b, therefore, certainly do not carry the information of the IMSIb of MSISDNb and the user b MSC-Number under current among the RoutingInfoForSM-Res, at this moment, SMC waits until that MSISDNb sends this short message when the position is upgraded before the deadline again, and its process of transmitting is with common Mobile-Terminated Short Message.
The calling subscriber of another part is c for a called subscriber, and note is made SMSa-c, comprises MSISDNa among this SMSa-c, MSISDNc and prefix (prefix) and Content, and this prefix is self-defined by operator, for example " from the Redirection Information of MSISDNb: ".SMC sends the process of SMSa-c with common Mobile-Terminated Short Message.
By multiple forwardings, SMC is during according to the transmission SMSa-b of DeliverSMSToSubscriber sign for fear of same short message, inserts in SMSa-b and changes sign before suppressing, to avoid giving MSISDNc this short-message foreward turning once more; When changeing short message SMS a-c before SMC sends, also need insert the preceding commentaries on classics sign of inhibition or this short message is the sign of preceding commentaries on classics short message, because user c has also registered preceding commentaries on classics, and the short message that causes MSISDNa is issued MSISDNb is forwarded to the situation of MSISDNx before final to avoid.
After SMSa-c sends successfully, after SMC is checked through and comprises the NotifySubscriberForwardSMSSuccess sign among the RoutingInfoForSM-Res, the SMC structure also sends new short message, the caller of the short message that this is new is user c, called is user b, note is made SMSc-b, comprise MSISDNc among this SMSc-b, MSISDNb and Content, wherein, content of short message (Content) can be self-defined by operator, and SMC change to suppress sign before also need inserting in SMSc-b, sends to MSISDNc once more to avoid this short message.
After MSC sent SMS message at every turn and finishes, all the response message of returning according to terminal (UE/MS) was returned the response that issues the MT short message to SMC.
So far, realized Short Message Service Call forwarding.And, the short message that changes before user b can obtain according to the needs of self, and can know the short message that whether forwarding subscriber has successfully received is changeed before this.
Above-mentioned SMC sends when waiting for that according to the SMSa-b needs of the transmission of DeliverSMSToSubscriber sign the position is upgraded before the deadline again, send SMS message when sending routing information to HLR once more for fear of SMC, always carry redundant Short Message Service Call forwarding information among the RoutingInfoForSM-Res that HLR returns, do not return the MSC Number at IMSIb and user b place and cause endless loop, can take following measure:
SMC obtains notification message (the Alert SC from HLR, SC is SMC), in the short message that HLR sends sends routing information, also increase once more and suppress Redirection Information (suppressForwardInfo) sign, like this, when HLR handles the short message routing iinformation, find to exist the suppressForwardInfo sign, then do not reexamine the Short Message Service Call forwarding information of user's registration, thereby avoid HLR once more Redirection Information to be sent to SMC, to alleviate network burden.
If user b registration is Call Forwarding Unconditional, and has also registered still to send SMS message and notified the information of self when changeing short message before successfully receiving to self and forwarding subscriber c, and the current attachment state that is in of user b.Then in the RoutingInfoForSM-Res that HLR returns, not only carry MSISDNc, DeliverSMSToSubscriber sign and NotifySubscriberForwardSMSSuccess sign, also carry the MSC-Number at IMSIb and user b place, at this moment, behind the RoutingInfoForSM-Res of SMC parsing from HLR, to send these two short messages of SMSa-b and SMSa-c simultaneously immediately, its processing procedure and the foregoing description are identical.
It is above-mentioned that to register Short Message Service Call forwarding information with called subscriber b in HLR be that example describes.The user also can register Short Message Service Call forwarding information in SMC, its implementation procedure is as follows:
If what SMC checked out user's registration is Call Forwarding Unconditional, the relevant information of then direct HLR inquiry forwarding subscriber under forwarding subscriber, and send SMS message to this forwarding subscriber according to the information that HLR returns, its implementation procedure is consistent with common short message service process.
If what SMC checked out user's registration is to change before separating, then SMC at first the HLR under the called subscriber send and to get the short message route data, if HLR this moment returns user's IMSI and the user b MSC-Number address under current, then illustrate this user current be attachment state; And carry out subsequent treatment according to common short message service process; If HLR returns failure response, and the error reason value is separated (absentSubscriberSM) for the user, then SMC thinks that the user is in released state, and change before triggering and handle, promptly the HLR under forwarding subscriber inquires about the relevant information of forwarding subscriber, and sends SMS message to this forwarding subscriber according to the information that HLR returns.
Can also comprise in the Short Message Service Call forwarding information that the user registers in SMC and whether still send SMS message to self and or notify self information when before forwarding subscriber is successfully received, changeing short message.Its processing mode and user register Short Message Service Call forwarding information processing process basically identical in HLR, so being in by SMC, difference detects Short Message Service Call forwarding information, and do respective handling, rather than detect Short Message Service Call forwarding information by HLR according to detected Redirection Information.Because treatment step is identical, no longer describe in detail herein.
No matter be in HLR or commentaries on classics before registration and the cancellation in SMC, all can adopt following several mode:
1) unstructured supplementary service data (USSD, Unstructured Supplementary ServiceData) mode.This mode is meant uses different command codes to represent to change before short message Call Forwarding Unconditional and the short message Detached, each USSD comprises the transferred number parameter, deliverSMSToSubscriber flags parameters and NotifySubscriberForwardSMSSuccess flags parameters in going here and there.
2) operation Room mode.This mode is meant that the user arrives registration of the operation Room and cancellation Short Message Service Call forwarding.
3) manual service liaison mode.This mode is meant that the user dials Service Phone to the business hall, helps registration and cancellation Short Message Service Call forwarding by operation Room attendant.
4) the Internet (Internet) mode.For for commentaries on classics mode before the HLR registration, this mode is meant that the user uses Internet, revises the Short Message Service Call forwarding information among the HLR under the guarantee of certain security mechanism, and in order to ensure information security, these modifications will obtain the keeper's of operator affirmation.Because this mode needs the HLR open interface, thereby has certain risk.For for commentaries on classics mode before the SMC registration, it is relatively more convenient to use this mode.
User for commentaries on classics mode before the HLR registration can also use intelligent access service liaison mode.This mode is meant that definition one assigned number is the Short Message Service number, after being switched on, will trigger this access service number GSM Service Control Function (gsmSCF) logic entity, collect relevant information by interactive voice, gsmSCF revises (ATM by random time, Any Time Modification) interface is revised the Short Message Service Call forwarding data among the HLR, thereby realizes registration and cancellation Short Message Service Call forwarding.Because the Short Message Service Call forwarding data are new content, so ATM message need be done respective extension.
Owing to be that SMC produces the short message ticket.Use preceding commentaries on classics mode of the present invention, SMC can charge to the called subscriber by number of times according to called subscriber's demand information, and for example SMC can have following control point:
1) SMSa-c sends successfully, and the recipient is MSISDNc, is designated as Ta-c;
2) SMSa-b sends successfully, and the recipient is MSISDNb, is designated as Ta-b;
3) SMSa-c sends successfully, changes the short message success before the MSISDNb, is designated as Tforward;
4) MSISDNb receives the informing message of SMSc-b, is designated as Tnotify;
Make that MSISDNb is the expense that short message called user bears Ta-b+Tforward+Tnotify, make that MSISDNc is the expense that the Short Message Service Call forwarding user bears Ta-c, with regard to present charging way, the called subscriber who receives short message is normally free, and the expense of the Ta-c that Ta-b that promptly short message called user bears and Short Message Service Call forwarding user bear all is 0.
Above-mentioned charging way is born the charging way of the short message expense that starts to existing message calling user, without any influence.Certainly, also can there be different charging ways in each operator.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
