Description
Technical field
The present invention relates to the Multimedia Message technology, relate in particular to a kind of between network method for transmitting multimedia message.
Background technology
Mobile number carries and is meant that the mobile subscriber changes into the mobile operator that it provides service, and keeps the constant service of mobile terminal number.Before mobile number carried enforcement, the mobile subscriber was if want to change to the mobile operator that it provides service, and its mobile terminal number also will change, and this user must in time notify other people with new digit, otherwise can be out of touch, and this has brought very big inconvenience to the user.And implement after mobile number carries, the user can change service network easily, obtain better service, and number remains unchanged, and can not be affected with other people telephone contact.After multimedia messaging service, MMS realized that mobile number carries, after the mobile subscriber changed service network, all Multimedia Messages of issuing this user still can correctly be sent on the customer mobile terminal.
It is that redirection of router by the Signalling Transfer Point in the Signaling System Number 7 net is accomplished to HLR is realized that the number of mobile calls carries.Called for connecting, for providing serving mobile switching center (MSC), the calling subscriber needs to inquire about the attaching position register (HLR) of this number correspondence according to called mobile terminal number, obtain called current place service MSC, carry out call proceeding then.Because there is corresponding relation mobile terminal number and HLR address, the Signaling System Number 7 net can be routed to correct HLR with position enquiring message according to mobile terminal number.After number carried, Subscriber Number did not change, still corresponding original HLR, but user-dependent information is kept among the new HLR, and position enquiring message must correctly be sent to new HLR, could obtain this user's service MSC.The Signalling Transfer Point of supporting mobile number to carry in the Signaling System Number 7 net can be inquired about internal database or external data base according to mobile terminal number, obtain the routing address of the affiliated new HLR of this user, the destination address in the position enquiring message is replaced with the address of new HLR.
It also is that redirection of router by the Signalling Transfer Point in the Signaling System Number 7 net is accomplished to HLR is realized that the number of short message carries.For sending SMS message to the recipient mobile subscriber, short message service center needs to inquire about the HLR of this number correspondence according to mobile terminal number under the transmit leg, obtains the current place service of recipient MSC and carries out the short message forwarding then.Number carries the redirection process of the position enquiring message in the redirection process calling of short message routing inquiry message identical.In the GSM network, this query messages is MAP-SRI-FOR-SM, and in cdma network, this query messages is SMSREQ.
Mobile number carries and relates to a plurality of mobile operator, suppose that transmit leg user and recipient user belong to two mobile operator respectively, the third-party operator specializes in MMS internetworking business, and recipient user is that mobile number carries the user, and Multimedia Message transmits flow process and consults shown in Figure 1:
A1: after transmit leg user attaching multimedia messaging service, MMS center (MMSC) MMSC1 receives the Multimedia Message of originating party submission, at first query subscriber database judges whether the recipient is this MMSC user, if then directly to recipient's issuing message, otherwise initiate the short message routing inquiry according to recipient's mobile terminal number of this message.If it is GSM user that MMSC1 can judge the recipient, then construct and initiate GSM short message route request information SRI_for_SMS, wherein the Subscriber Number parameter is mobile subscriber's telephone number (MSISDN), SCCP (SCCP) layer destination-address is global title (GT is used for the addressing between same carrier network inside or the different operators network) number based on MDISDN; If it is CDMA user that MMSC1 can judge the recipient, then construct and initiate CDMA short message route request information SMSREQ, wherein the Subscriber Number parameter is mobile number book number (MDN), SCCP layer destination-address is the GT number based on MDN; If MMSC1 can't judge recipient's user type, can select both one of attempt inquiry, reattempt another kind after the inquiry failure.
A2: the Signalling Transfer Point STP1 that the support mobile number that links to each other with MMSC1 carries (MNP) receives and comprises the SCCP message of carrying short message routing inquiry MAP message, according in the destination-address based on the GT number of mobile terminal number, inquire about outside number portability database or intercom number and carry database, obtain No. seven addresses that Subscriber Number carries the affiliated HLR-B in back, replace the destination address of receiving in the message with it, message is re-routed HLR-B by the Signaling System Number 7 net.Before number carried, because No. seven addresses of mobile terminal number and its affiliated HLR have corresponding relation, SGW can connect this message and be routed to this HLR.
After a3:HLR-B receives short message routing inquiry MAP message, obtain corresponding user identification code (the GSM net is that IMSI, CDMA net are MIN) according to mobile terminal number inquiry internal database in the message, in the response message of short message route requests, return to MMSC1.
After a4:MMSC1 obtains the recipient user's that HLR-B returns mobile identification number (GSM net IMSI, CDMA net MIN), inquiry internal database or external data base, obtain the affiliated mobile operator information of recipient user, and determine next MMSC address (domain name or IP address) with this.If belong to an operator together with transmit leg, but belong to different MMSC, then give recipient MMSC with MM4 Forward.REQ (transmitting the request message of customer multi-media message between the MMSC) forwards by the MM4 interface, by this MMSC to recipient user's transmitting multimedia message.If receiving-transmitting sides does not belong to same operator, then MMSC1 gives the MM4_Forward.REQ forwards by the MM4 interface gateway MMSC2 of the external intercommunication of Home Network.
A5:MMSC2 receives MM4_Forward.REQ, returns MM4_Forward.RES message to MMSC1.
B1～b5: be similar to a1～a5, after MMSC2 inquiry HLR-B obtains recipient's mobile identification number, inquiry internal database or external data base are judged recipient's operator, if belong to this operator, then forwards is belonged to MMSC to the recipient by the MM4 interface, if belong to other operators, then Multimedia Message is forwarded to the Interworking GateWay MMSC3 of operation MMS interconnect services by the MM4 interface.
C1～c5: be similar to a1～a5, after MMSC3 inquiry HLR-B obtains recipient's mobile identification number, inquiry internal database or external data base are judged recipient's operator, and Multimedia Message are forwarded to the gateway MMSC4 of recipient's belonging network by the MM4 interface.
D1～d5: be similar to a1～a5, after MMSC4 inquiry HLR-B obtains recipient's mobile identification number, inquiry internal database or external data base are judged the MMSC5 that the recipient belongs to this operator, and Multimedia Message is forwarded to MMSC5 under the recipient by the MM4 interface.After MMSC5 received message to the user under the recipient, the inquiry internal database determined it is this MMSC user, then starts to the MM delivery flow process of user terminal.
From on can find out, owing to do not represent the information of user's operator among the MM4 interface message MM4_Forward.REQ between the MMSC, cause MMSC under the transmit leg and under the recipient each MMSC between the MMSC all to carry out short message routing inquiry mobile identification number (IMSI or MIN) with acquisition recipient user, thereby exist handling process complexity, the network resource consumption of each MMSC big, response speed is slow and shortcoming such as overall cost height.
