Embodiment
The invention provides a kind of in the method and the system thereof that are not signing realization roaming between the roaming agreement network, the central principle of this scheme is, by third party's network to main IMSI (International MobileSubscriber Identity, IMSI International Mobile Subscriber Identity) and the conversion between the secondary IMSI, realize the function of the interior user of Home Network in the netsurfing of not signing roaming agreement, like this, for new mobile operator, can't sign with the operator of other network under the situation of roaming agreement in a short time, realize fast the user's roaming function in these networks in the Home Network, thereby provide services of roaming for the present networks user.
As shown in Figure 1, the present invention relates to three networks, promptly former network, current network and third party's network are described for convenient, suppose that now three networks are respectively A, B, C.Wherein, the A network is former network, network as certain operator, A and C networks sign roaming agreement, the user terminal of A network home is equipped with SIM (the Subscriber Identity Module of two IMSI, Subscriber Identity Module) card, wherein main IMSI is registered in HLRa (the Home Location Register of A network, attaching position register), secondary IMSI is registered in the HLRc of C network, all corresponding MSISDN (the Mobile stationinternationalISDN number of these two IMSI; Mobile Subscriber International ISDN number); The B network is a current network, i.e. the network at the current place of the A network user, B and A network are not signed roaming agreement, B and C networks sign roaming agreement; The C network is third party's network, and its network internal is provided with two ISMI servers, and the corresponding relation between described couple of described two IMSI of ISMI server record is so that realize two conversions between the IMSI.
Described A, B, C network include following unit: STP (signaling transfer point, Signalling Transfer Point), are used to finish signaling message and handle and transmit; HLR (Home Location Register, attaching position register) is used to finish the management of mobile subscriber business data management and location information data; SMSC (Short Message Service Center Short Message Service Center) is used to finish the short message processing that the mobile subscriber submits to; MSC/VLR (Mobile Switching Center/Visitor Location Registe, mobile switching center) is used to finish the exchange and the signaling control of circuit switched type business.Fig. 1 and below description in, the STP of C network is represented titled with representing the unit of this network with A, B, lowercase that C is corresponding in above-mentioned each back, unit as STPc.
When the user terminal in the A network roams in the B network, according to the present invention, A network user terminals in the B network can be finished various and relevant flow process and the communication services of communication, as the position more new technological process, and other user terminal carry out call business, short message service, various value-added services etc.With reference to the accompanying drawings with the position more new technological process, and other user terminal between call business, short message service be that example illustrates loaming method of the present invention.
One, the position is upgraded
The user terminal of A network moves to another lane place from a lane place in the B network, when perhaps entering the B network at first, the A network user terminals can be initiated position updating process, with reference to Fig. 2, moving to another lane place from a lane place with the user terminal of A network in the B network below is that example is described position updating process.
Step 201, since the A network not with B networks sign roaming agreement, use main IMSI can't finish authentication and position updating process at VLRb and HLRa.Be the completing place renewal process this moment, can only make secondary IMSI, at this moment can switch by automatic or manual and use secondary IMSI to send location update request message (MAP_UPDATE_LOCATION) to the STPc of C network, described location update request message comprises secondary IMSI.
Step 202, when this location update request message is sent to STPc, the two IMSI servers of STPc inquiry, find the main IMSI number of secondary IMSI number correspondence in the location update request message, secondary IMSI in message number is replaced with main IMSI number, and after revising the HLRa address that called GT (global title) is main IMSI correspondence, location update request message is transmitted to HLRa by STPc and STPa.
After step 203, HLRa receive location update request message, carry out subscription authentication, pass through the STPc that STPa is transmitted to delete position data-message (MAP_CANCEL_LOCATION) on the C network then.In order to allow this message pass through the STPc of C network again so that the main IMSI number in the message is replaced with secondary IMSI number, can set the GT translation data by STPa, DPC (destination signaling point) after the translation of the GT sign indicating number of VLRb1 is pointed to the STPc of C network, and the TT of the called GT after will translating (Translation Type) value is set at a special value (as 5) and other parts is remained unchanged.
After step 204, STPc receive that TT is the delete position data-message of particular value (as 5), the two IMSI servers of inquiry, find the secondary IMSI number of this main IMSI number correspondence, main IMSI number in the message is replaced with secondary IMSI, and to revise caller GT be the HLRc address of secondary IMSI correspondence, and at last the TT value among the called GT being remodified is 0 back by STPc and STPb with this forwards to current MSC/VLRb1.
After the VLRb1 of step 205-206, mobile switching centre receives the delete position data-message, the position data of deletion user terminal from VLRb1, then VLRb1 sends delete position data response message (MAP_CANCEL_LOCATION_ACK) to STPc, STPc is converted to main IMSI with secondary IMSI in this message, gives HLRa with this forwards then.
207, HLRa sends to STPc and inserts subscriber data message (MAP_INSERT_SUBSCRIBER_DATA), during through STPa, in order to allow this message pass through the STPc of C network again so that the main IMSI number in the message is replaced with secondary IMSI number, can set the GT translation data by STPa, DPC (destination signaling point) after the translation of the GT sign indicating number of VLRb1 is pointed to the STPc of C network, and the TT value of the called GT after will translating is set at a special value (as 5) and other parts is remained unchanged.
After step 208, STPc receive that TT is the insertion subscriber data message of particular value (as 5), the two IMSI servers of inquiry, find the secondary IMSI number of this main IMSI number correspondence, IMSI number in the message is replaced with secondary IMSI number, and to revise caller GT be the HLRc address of secondary IMSI correspondence, and at last the TT value among the called GT being remodified is 0 back by STPc and STPb with this forwards to VLRb2.
After the VLRb2 of step 209-210, mobile switching centre receives and inserts subscriber data message, in VLRb2, insert the position data of user terminal, VLRb2 sends to STPc and inserts user data response message (MAP_INSERT_SUBSCRIBER_DATA_ACK) then, STPc is converted to main IMSI with secondary IMSI in this message, gives HLRa with this forwards then.
Step 211, HLRa carry out subscription authentication after receiving and inserting the user data response message, through STPa the STPc that response message (MAP_UPDATE_LOCATION_ACK) is transmitted to the C network are upgraded in the position then.In order to allow this message pass through the STPc of C network again so that the main IMSI number in the message is replaced with secondary IMSI number, can set the GT translation data by STPa, DPC (destination signaling point) after the translation of the GT sign indicating number of VLRb2 is pointed to the STPc of C network, and the TT value of the called GT after will translating is set at a special value (as 5) and other parts is remained unchanged.
After step 212, STPc receive that TT is the position renewal response message of particular value (as 5), the two IMSI servers of inquiry, find the secondary IMSI number of this main IMSI number correspondence, IMSI number in the message is replaced with secondary IMSI number, and to revise caller GT be the HLRc address of secondary IMSI correspondence, and at last the TT value among the called GT being remodified is 0 back by STPc and STPb with this forwards to VLRb2.
Two, call business
A network user terminals in the B network can be conversed with other user terminal at any time.When making a call, following two kinds of situations can be arranged: caller and called.
A network user terminals in the B network is during as caller, and promptly when other user terminal made a call, because of this call flow is identical with the call flow of signed roaming agreement, the application no longer described.
Be in A network user terminals in the B network when called, when promptly receiving the calling that the user terminal of other network initiates, with reference to Fig. 3, the A network user terminals is that example illustrates the call business in the roam procedure in the user terminal calling B network in the B network to be in below.
Step 301-302, call out when roaming into the A network user terminals of B network when the user terminal in the B network, B network MSC initiates to get route messages (MAP_SEND_ROUTING_INFORMATION) through STPc to HLRc, during this message process STPc, STPc is transmitted to HLRa after translating by GT.
Step 303-304, HLRa send to this user's present located VLRb according to Mobile Subscriber International ISDN Number and get roaming number message (MAP_PROVIDE_ROAMING_NUMBER), during this message process STPa, will get the STPc that the roaming number forwards is given the C network through STPa then.In order to allow this message pass through the STPc of C network again so that the main IMSI number in the message is replaced with secondary IMSI number, can set the GT translation data by STPa, DPC (destination signaling point) after the translation of the GT sign indicating number of VLRb is pointed to the STPc of C network, and the TT value of the called GT after will translating is set at a special value (as 5) and other parts is remained unchanged.STPc receive TT be particular value (as 5) get roaming number message after, the two IMSI servers of inquiry, find the secondary IMSI number of this main IMSI number correspondence, IMSI number in the message is replaced with secondary IMSI number, and to revise caller GT be the HLRc address of secondary IMSI correspondence, and at last the TT value among the called GT being remodified is 0 back by STPc and STPb with this forwards to VLRb.
Step 305-306, VLRb send to STPc and get roaming number response message (MAP_PROVIDE_ROAMING_NUMBER_ACK), when this is got the roaming number response message and is sent to STPc, the two IMSI servers of STPc inquiry, find the main IMSI number of this secondary IMSI number correspondence, IMSI number in the message is replaced with main IMSI number, and after revising the HLRa address that called GT is main IMSI correspondence, will get the roaming number response message by STPc and STPa and be transmitted to HLRa.
Step 307-308, HLRa are transmitted to MSC by getting route response message (MAP_SEND_ROUTING_INFORMATION_ACK) by STPa and STPc with the roaming number that obtains at last, like this, MSC can continue according to the roaming number that obtains, thereby the user terminal in the B network is conversed with the A network terminal that is in the B network.
This gets route response message is transmitted to the C network through STPa STPc.When allowing this message pass through the STPc of C network again, main IMSI number in the message is replaced with secondary IMSI number, can set the GT translation data by STPa, DPC (destination signaling point) after the translation of the GT sign indicating number of VLRb is pointed to the STPc of C network, and the TT value of the called GT after will translating is set at a special value (as 5) and other parts is remained unchanged.STPc receive TT be particular value (as 5) get roaming number message after, the two IMSI servers of inquiry, find the secondary IMSI number of this main IMSI number correspondence, IMSI number in the message is replaced with secondary IMSI number, and to revise caller GT be the HLRc address of secondary IMSI correspondence, and at last the TT value among the called GT being remodified is 0 back by STPc and STPb with this forwards to MSC.
Should note, the A network user terminals is that example has illustrated the call business flow process in the roam procedure in the user terminal calling B network in the B network to be in above, when the user terminal in other network is called out in the B network A network user terminals, only 301-302 distinguishes to some extent in steps, when caller is in the A network, can omit step 301-302, when caller was in other network except that A and B, step 301-302 got route messages for sending to A network HLR from caller place network.Step 303-308 is just the same, has just repeated no more here.
Three, short message service
When the user terminal in the A network is in the B network, can realize short message service.In realization short message service flow process of the present invention, the SMSC address of main IMSI correspondence is the SMSCa in the A network, and the SMSC address of secondary IMSI correspondence is the SMSCc of C network.Can will realize that short message service is divided into two parts: short message transmission flow, short message receive flow process.Below these two processes are described respectively.
1, short message transmission flow
When A network user terminal in home network or signed when sending note in the network of roaming agreement, use main IMSI number, SMMO (short message transmission) message directly is sent to the SMSCa of A network, mails to the purpose user terminal by SMSCa again.
When A network user terminal moves to the B network, when sending SMS message since the A network not with B networks sign roaming agreement, therefore when sending SMS message, use secondary IMSI number.Below with reference to Fig. 4 the process that the A network user terminals in the B network sends SMS message that is in is described.
Step 401-402, VLRb are to sending note MO (Mobile Originated initiates) message (MAP_MO_FORWARD_SHORT_MESSAGE) through the C network to SMSCa.During this message process STPc, the two IMSI servers of STPc inquiry, after finding the main IMSI number of this secondary IMSI number correspondence, secondary IMSI in message number is replaced with main IMSI number, and after revising the SMSCa address that called GT is main IMSI correspondence, give SMSCa by STPc and STPa with this forwards, issue target terminal by SMSCa then.
403-404, SMSCa receive note MO message, return MO response message (MAP_MO_FORWARD_SHORT_MESSAGE_ACK) by STPc to VLRb, through STPc the time, give VLRb with forwards then.
2, short message receives flow process
A network user terminals in roaming into the B network receives in the process of short message, and the short message service center of transmit leg network at first obtains the address of the A network user terminals in the above-mentioned B of the roaming into network, according to the address that obtains short message is issued user terminal then.The transmit leg network can be divided into following two kinds of situations, a kind of situation be not with the network of A signature roaming agreement, another kind of situation be the A network or with the network of A networks sign roaming agreement.Below above-mentioned two kinds of situations are described respectively.
With reference to Fig. 5, at first describe the first situation short message and receive flow process, sending SMS message for the A network user terminals that is in the B network with the user terminal in the B network below is the address process that the example explanation obtains to be in A network user terminals in the B network.
Step 501-502, SMSCb send note through STPc to HLRc and get route messages (MAP_SEND_ROUTING_INFO_FOR_SM), and during this message process STPc, STPc gets route messages according to Mobile Subscriber International ISDN Number with note and is transmitted to HLRa through STPa.
After step 503-504, HLRa handle note and get route messages, return note through STPc to SMSCb and get route response message (MAP_SEND_ROUTING_INFO_FOR_SM_ACK), during this message process STPc, STPc finds that the TT value of GT is a particular value, the two IMSI servers of inquiry, after finding the secondary IMSI number of this main IMSI number correspondence, IMSI number in the message is replaced with secondary IMSI number, and after revising the SMSCb address that called GT is main IMSI correspondence, give SMSCb with this forwards by STPc and STPb.
At last, short message issuing is given the A network user terminals that is in the B network by SMSCb.
