Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Among the present invention, open at terminal called under the situation of roam prompting service, when calling terminal sends when calling out to terminal called, system judges whether calling terminal is dialled the number that cries corresponding with the current location of terminal called, dial the current location of the number that cries and terminal called not at once at calling terminal, send roam prompting to calling terminal, inform the roaming information of the relevant terminal called of calling terminal.
Roam prompting can be the system message or the voice suggestion of textual form, clearly, voice prompting mode does not have specific (special) requirements to the type of calling terminal, the scope of application is more extensive, when calling terminal is landline telephone, the general not reception of back-up system message, but still can receive voice suggestion.
Comprise following information in the roam prompting:
(1) whether terminal called is in roaming state;
(2) the roaming rate of terminal called under roaming state;
(3) payer of wandering fee;
(4) call treatment suggestion.
Concrete roam prompting can be:
(1) be in roaming state when terminal called, when calling terminal used the original number of terminal called to call out, system was roamed to calling terminal prompting terminal called, and informs the roaming rate that calling terminal is current, and the information such as payer of wandering fee.This moment, system handled to advise it being that the prompting calling terminal adds group roaming identification code to calling sent by calling terminal.Calculate different roaming rates, the roaming identity sign indicating number that different roaming places is corresponding different in order to distinguish.The concrete form of roaming identity sign indicating number is by the home network setting of terminal called, can be as the roaming identity sign indicating number as #86#, 000 etc.
(2) be in non-roaming state when terminal called, when called number was not the original number of terminal called, system sent roam prompting to calling terminal, informed its terminal called not at roaming state, and the prompting calling terminal uses the original number of terminal called to call out.
(3) change when the terminal called roaming place, calling terminal adds the current location of the roaming identity sign indicating number dialled and terminal called not at once, and system is to the roaming identity sign indicating number of calling terminal prompting right, and new roaming rate.
Accordingly, be not in roaming state at terminal called, calling terminal uses the original number of terminal called to call out, and perhaps terminal called is in roaming state, and calling terminal adds when having dialled correct roaming identity sign indicating number calling, and system does not send roam prompting to calling terminal.
When calling terminal was known terminal called and is in roaming state and still calls out, wandering fee was rational by the calling terminal payment.Certainly, terminal called also can be when opening the roam prompting service, increase the setting that wandering fee is still paid by terminal called, it is typical in a reimbursement of expense password is set, and password informed certain customers in advance, as the relatives, good friend etc. of oneself, if these users have inputed the reimbursement of expense password when making a call, the system verification password is legal, then by terminal called payment wandering fee.
Above-mentioned roam prompting can further include the prompting user and is chosen in and continues under the situation that keeps current connection to call out, and perhaps hangs up the information that current connection is called out again, as " continue to call out by 1, withdraw from by 0 " etc.Clearly, in order to improve service, system can increase other more informations.
Fig. 1 is that example shows realization of the present invention with the GSM network, because WCDMA (Wideband CodeDivision Multiple Access, Wideband Code Division Multiple Access (WCDMA)) core net of system and GSM are basic identical, so following content is equally applicable to the WCDMA system, repeat no more.For the purpose of simplifying the description, only provide part related to the present invention in the diagram, other parts are omitted.
In the present invention, GSM network support CAMEL (Customised Applications for MobileNetwork Enhanced Logic, the mobile network strengthens the customized application logic) suggestion, this suggestion is by ETSI (European Telecommunications Standards Institute, the European Telecommunication Standard committee) the mobile intelligent net standard that is exclusively used in gsm mobile communication system of Zhi Dinging, be used for providing IN service to the user at the GSM net, about CAMEL further content ask for an interview GSM02.78, agreement such as GSM03.78 and GSM09.78, the present invention quotes at this.
Roam prompting business among the present invention belongs to the CAMEL business, GSM user is if will use the CAMEL business, just must become the CAMEL service-user, this just need increase the information about the CAMEL business, i.e. CSI (CAMEL Subscription Information) on original user profile basis.CAMEL Subscription Information comprises O-CSI (CAMEL Subscription Information of making a start) and T-CSI (terminal CAMEL Subscription Information).The user of CAMEL business of having applied for making a start has O-CSI, and has applied for that the user of terminal CAMEL business has T-CSI.In the present invention, the called subscriber has applied for terminal CAMEL business, has T-CSI, and T-CSI is kept among the HLR (Home Location Register, attaching position register) of terminal called.
Terminal called roams into roaming network 300 from home network 200, and calling terminal makes a call to terminal called by network 100 or in the home network 200 of terminal called, and calling terminal is portable terminal or landline telephone.When calling terminal is landline telephone, calling terminal is by PSTN (Public SwitchingTelephone Network, public switched telephone network (PSTN)) 400 is connected to GSMC (Gateway MobileSwitching Center, GMSC (gateway mobile switching center)), connect with mobile network 100, terminal called has been opened the roam prompting business to home network 200 applications.
To the terminal called request of making a call, MSC sends the calling route requests to HLR to calling terminal by MSC (Mobile service Switching Center, mobile services switching centre).HLR has preserved the information relevant with terminal called, comprises roaming authority, basic service, supplementary service and current location information etc., thereby calls out required related datas such as routing iinformation for MSC provides to set up.HLR returns the route response of being with T_CSI to MSC when judging that terminal called has been opened the roam prompting business, MSC triggers T_CSI.
SCP (Service Control Point, service control point), SSP (Service Switch Point, Service Switching Point) and IP (Intelligent Pe such as heral, ip intelligent peripherals) are the relevant components parts of mobile intelligent net.
After MSC triggered T_CSI, to sending Initial Detection Point message, SCP judged whether calling terminal is dialled the number that cries corresponding with the current location of terminal called, if not corresponding then to SSP transmission roam prompting service request.SSP detects the roam prompting service request of SCP and communicates by letter with SCP, and response is made in the request of SCP, sends roam prompting to calling terminal.
SSP can be voice suggestion to the roam prompting that terminal called sends, and is specifically finished by IP, and it accepts the control of SCP, carries out the specified voice roaming prompting play operation of SCP service logic.
VLR (Visited Location Register, VLR Visitor Location Register) for information about whole of the terminal called that enters its area of coverage have been stored, as the information such as roaming number of terminal called, provide the necessary condition of setting up call proceeding for the terminal called of having registered.HLR sends the roaming number request to VLR, obtains the roaming number of terminal called.HLR sends to MSC with the roaming number of terminal called, is established a communications link between calling terminal and terminal called by MSC.
Fig. 2 shows realization flow of the present invention:
In step S201, calling terminal makes a call to terminal called, comprises the originated call that calling terminal is initiated terminal called, perhaps the calling terminal subsequent voice calls of carrying out according to roam prompting or call out again etc.
In step S202, system judges whether calling terminal is dialled the number that cries corresponding with the current location of terminal called, is then direct execution in step S205, otherwise execution in step S203.
When belonging to one of following situation, it is corresponding with the current location of terminal called that calling terminal is dialled the number that cries:
(1) terminal called is in roaming state, and called number adds has dialled correct roaming identity sign indicating number;
(2) terminal called is in non-roaming state, and called number is the original number of terminal called.
Accordingly, belong to one of following situation, that calling terminal is dialled the number that cries is not corresponding with the current location of terminal called:
(1) terminal called is in roaming state, and called number is the original number of terminal called;
(2) terminal called is in roaming state, adds the roaming identity sign indicating number mistake of dialling, and is not corresponding etc. as roaming identity sign indicating number and roaming place.
(3) terminal called is in non-roaming state, and called number is not the original number of terminal called.
In step S203, system sends roam prompting to calling terminal.
In step S204, calling terminal is called out according to the roam prompting of system.
In step S205, under the correct situation of the dial number of calling terminal, system is that calling terminal and terminal called establish a communications link, and realizes communicating by letter between calling terminal and the terminal called.
Fig. 3～Fig. 7 show in detail terminal called be in the roaming with non-roaming state under several different call flows.For the purpose of simplifying the description, the content for the same steps as sign no longer is repeated in this description.
In Fig. 3, terminal called is in roaming state, and calling terminal uses the original number of terminal called to call out, and system sends roam prompting to calling terminal.
Among the step S301, calling terminal uses the original number of terminal called to make a call to terminal called;
Among the step S302, MSC sends route request information to HLR, the routing iinformation of request terminal called;
Among the step S303, HLR has the T_CSI of terminal called to the route response message that MSC returns in the route response message, and this T_CSI has indicated the address of corresponding SCP;
Among the step S304, MSC triggers this T_CSI, and sends Initial Detection Point message to SCP, carries information such as the MSC sign of calling number, called terminal number, terminal called and VMSC (VisitedMSC, the MSC of roaming network) sign in the message;
Among the step S305, SCP is by relatively the MSC sign and the VMSC of terminal called identify, determine that terminal called roams, and calling terminal uses the original number of terminal called to call out, then send the relevant parameter of relevant roam prompting to MSC, as roam rate, roaming identity sign indicating number etc., and MSC transfers to SSP with relevant parameter and delivers IP, and IP plays the voice roaming prompting to calling terminal;
Among the step S306, SSP notice SCP roam prompting finishes;
Among the step S307, SCP issues P﹠amp to IP; C (Prompt ﹠amp; Collect user information, prompting ﹠ collects user profile), request IP collects the digits for the calling terminal playback, and IP adds group roaming identity sign indicating number to the calling terminal prompting to be continued to call out;
Among the step S308, calling terminal is received the playback of the IP prompting that collects the digits, and adds according to prompting and dials the roaming identification code, continues to make a call to terminal called, and IP notifies SCP with call information;
Among the step S309, SCP checks the call number of calling terminal, judges that the number of calling terminal calling is correct, and decision continues to call out, and sends continuation to MSC and calls out (Continue) message;
Among the step S310, MSC continues to send route request information to HLR, and this route request information suppresses T-CSI, no longer sends roam prompting to calling terminal, continues call treatment;
Among the step S311, HLR sends PRN (Provide Roaming Number Provides Roaming Number) request to VLR, the roaming number of request terminal called;
Among the step S312, VLR returns the roaming number information PRN ACK of terminal called to HLR;
Among the step S313, HLR returns route response message to MSC, carries the roaming number of terminal called in the route response message;
Among the step S314, MSC continues according to the MSRN (Mobile Station Roaming Number Mobile Station Roaming Number) of terminal called and VMSC, carries out normal talking, can trigger other business in this process, such as chargeing etc. for calling out.
Among Fig. 4, calling terminal is known terminal called and is in roaming state, directly add group roaming identity sign indicating number and make a call to terminal called, but the roaming identity sign indicating number is not corresponding with the current location of terminal called, and system sends roam prompting to calling terminal.
In step S401, calling terminal adds group roaming identity sign indicating number terminal called is made a call;
In step S405, SCP finds that the roaming place of terminal called changes, corresponding roaming identity sign indicating number is also adjusted, it is not corresponding with the current location of terminal called that calling terminal adds the roaming identity sign indicating number of dialling, send roam prompting to calling terminal, inform that calling terminal need add the new roaming identity sign indicating number of dialling, and roam rate accordingly.
In step S408, calling terminal adds the roaming identity sign indicating number that sets right true to be continued to call out.
Among Fig. 5, terminal called finishes roaming, gets back to ownership place, and calling terminal adds group roaming identity sign indicating number and makes a call, and system sends roam prompting to calling terminal.
In step S505, SCP inspection calling terminal adds has dialled the roaming identity sign indicating number, and terminal called has been got back to ownership place, therefore sends roam prompting to calling terminal, inform the calling terminal terminal called not at roaming state, and the prompting calling terminal uses the original number of terminal called to call out;
In step S508, calling terminal uses the original number of terminal called to call out according to roam prompting.
Among Fig. 6, terminal called is in roaming state, and calling terminal adds the roaming identity sign indicating number that sets right true to be called out, and system does not send roam prompting to calling terminal.
Among Fig. 7, terminal called is not at roaming state, and calling terminal uses the original number of terminal called to call out, and system does not send roam prompting to calling terminal.
When roam prompting is the system message mode, to be correlated with the roaming parameter when sending to MSC at SCP, MSC is by the system message of text mode, as short message etc., send roam prompting to calling terminal, this moment, calling terminal need be hung up current connection, made a call again by the information of roam prompting, detailed process is similar to the above, repeats no more.
The present invention only is that example is described specific implementation process of the present invention in detail with the gsm mobile communication system, but the present invention is not limited to gsm system, also goes for other mobile communication system, as WCDMA or CDMA2000 etc.
