The method includes registering the business control point address of the user in original attribution position register and registering current attribution position register address in the business control point; sending via the original attribution position register the request of taking roaming number to the business control point, sending the request of taking route information from the business control point to the current attribution position register to obtain the route information of the called user and switching to the number carrying about user with the route information.
Description
Technical field
The present invention relates to that number carries technology in the communication network, particularly a kind of method that realizes that mobile number carries.
Background technology
Mobile number portability (MNP) is a kind of ability of user, and it allows the mobile subscriber to change the GSM CAMEL-Subscription-Information in same country, and need not change original Mobile Subscriber International ISDN Number (Mobile Subscriber International ISDN number).The mobile number portability can be divided into following two kinds of situations:
(1) the mobile operator number carries: the mobile subscriber selects different service providers in same message area, MSISDN is constant.
(2) the shift position number carries: the mobile subscriber changes homing position in same operator, MSISDN is constant.
The mode of realization MNP can be divided into the signal retransmission function, and (Signaling Relay Function is SRF) with the Intelligent Network dual mode.The difference on the opportunity of triggering according to business, realize that by the Intelligent Network mode number carries (NP) and is divided into two kinds of situations:
(1) before sending SRI message, be triggered to NPDB, judge whether the user is NP user, be called in the agreement called inquiry according to data analysis (Terminating call Query on Digit Analysis, TQoD);
(2) after HLR returns mistake, be triggered to NPDB, judge whether the user is NP user, be called in the agreement according to HLR distribution inquiry (QoHR, Query on HLR Release, QoHR).
According to the network difference that inquiry is taken place, be divided in number section home network (Number Range OwnerNetwork) inquiry and caller network (Orginating Network) and inquire about two kinds.
The QoHR scheme of number section home network inquiry is consulted shown in Figure 1, and its main process is as follows:
Though such scheme can realize that number carries, and has following shortcoming:
1, this scheme is had relatively high expectations to conventional network equipment.This scheme requires gateway exchange (GMSC/MSC) should have Service Switching Point (Service Switching Point, ability SSP); Should be able to communicate by the CAMEL agreement between SSP and the Service Control Point.
2, can not solve the short message problem of ported subscriber.Because in the MT of short message (MobileTerminal) flow process, short message service center need be mutual with MSC/VLR, need know NP user's roaming number, needs visit NPDB equally, and such scheme is by gateway exchange (GMSC/MSC) visit NPDB, and is just powerless for short message.If the support short message must face the problem of GMSC/MSC equally by the inquiry NPDB of short message service center oneself, need to change existing network equipment.
Summary of the invention
The object of the present invention is to provide a kind of method that realizes that mobile number carries,, and support short message service with the requirement of reduction to conventional network equipment.
Technical scheme of the present invention:
A kind of realization mobile number method capable of carrying is used for the mobile subscriber and changes network contraction information and do not change original Subscriber Number in certain zone, it is characterized in that the method comprising the steps of:
A, caller network are routed to originating network according to the distribution of number segment with the called number section;
The gateway MSC of B, originating network or the short messaging gateway attaching position register in this network sends to be got route messages or gets the short message routing iinformation, for ported subscriber, this attaching position register sends the request of application roaming number according to the Service Control Unit ADDress of user's registration to this service control point;
C, described service control point send the request of sending routing information according to the home network register address of user's registration to the attaching position register of user's subscription network, obtain roaming number by this attaching position register from Visited Mobile Switching Center, and roaming number is turned back to the gateway MSC of home network/or short messaging gateway;
The gateway MSC of D, original number home network arrives call proceeding according to the routing iinformation that obtains the mobile switching centre at user place; Perhaps the short messaging gateway of original number home network is forwarded to short message according to the routing iinformation that obtains the mobile switching centre at user place.
The present invention has following beneficial effect:
1, the present invention does not make any changes to existing network, and operator receives easily;
2, simultaneously voice-bearer and short message of the present invention done special support and need not short message service center;
3, the present invention is based on that intelligent network realizes because intelligent network can have business realizing to charge, can be according to the flexible charging that requires of operator, thus charge and operation on have advantage.

Embodiment
Consulting shown in Figure 2ly, in former home location register HLRA, carry (NP) user for number, is this user's VLR Visitor Location Register (VLR) address registration the service control point address of (being called for short SCP).Do not change for non-ported subscriber.In SCP, set up and store the mapping table of mobile subscriber's Mobile Subscriber International ISDN Number to existing home location register, promptly can find the existing home location register address of this user by MSISDN.After former ownership HLRA transmission application roaming number is operated to SCP, SCP parses this mobile subscriber's Mobile Subscriber International ISDN Number from this application roaming number (PRN) operation, inquire about local tables of data (being the mapping table that MSISDN arrives existing ownership HLR address) again, can obtain the address of existing attaching position register, SCP sends the routing number request of getting to existing attaching position register.
The calling procedure that carries the user of checking numbers is as follows:
Step 1: send initial address message (IAM), give originating network according to the distribution of number section with calling by the caller network;
Step 2: send and get route messages (SRI), get called subscriber's routing iinformation by gateway MSC GMSCA to attaching position register HLRA;
Step 3: attaching position register HLRA according to the address of the service control point (SCP) of this user registration (for non-ported subscriber, what register is the address of this user's the VLR Visitor Location Register VLR/ VMSC of mobile switching centre), send roaming number (PRN) request of getting to this service control point (SCP);
Step 4: the service control point (SCP) sends (SRI) request that sends routing information according to the address of the existing attaching position register HLRB of this user's registration to this attaching position register HLRB;
Step 5: attaching position register HLRB sends roaming number (PRN) request of getting to the Visited Mobile Switching Center/VLR Visitor Location Register VMSCB/MLRB of user visiting network;
Step 6: Visited Mobile Switching Center/VLR Visitor Location Register VMSCB/MLRB sends casual number request response message to attaching position register HLRB, to return roaming number;
Step 7: the location register HLRB of existing ownership sends the response message that sends routing information to the service control point (SCP), to return the present position of this user;

(3) service control point (SCP) obtains the information of this ported subscriber by Query Database (DB), comprising the address of this user's existing attaching position register HLRB;
(4) service control point (SCP) sends to routing iinformation (SRI) request to existing attaching position register HLRB, and waits for that existing attaching position register HLRB returns the response message (SendRouteing Info ack) of getting route messages;
In the step 8, the processing procedure of service control point (SCP) is as follows:
(1) service control point (SCP) parses the present roaming number MSRN of this ported subscriber (Mobile Station RoamingNumber) from the response message (SRI_ACK) of existing attaching position register HLRB;
(2) service control point (SCP) returns to former attaching position register HLRA to roaming number by getting roaming number response message (PRN_ACK).
Consult Fig. 4, the flow process that the short message of ported subscriber is handled is as follows:
Steps A: service center sends SMS message to short messaging gateway.
Step B: short messaging gateway is got the routing iinformation of short message to the register of the former ownership of user.
Step C: the register of former ownership finds that this user is ported subscriber, sends and gets the roaming number request to the affiliated service control point of this user.
Step D: service control point sends to send routing information and sends routing information to the existing attaching position register of this user, and receives from existing attaching position register and to receive the response.Service control point returns roaming number to the former attaching position register of this user.
Step e: former attaching position register is responded routing iinformation to short messaging gateway, and this short messaging gateway changes short message before mobile switching centre sends MT.
Step F: mobile switching centre sends to VLR Visitor Location Register and gets MT short message routing iinformation, and waits for the response of VLR Visitor Location Register.
Step G: mobile switching centre is to this transmitting short message by mobile terminal, and portable terminal returns the response result after receiving short message.
Step H: mobile switching centre sends delivery report to short messaging gateway after the short message that receives portable terminal is receiveed the response.
