Description

Number of short message carries implementation method and system

Technical field

The present invention relates to the communications field, carry implementation method and system in particular to a kind of number of short message.

Background technology

Number carries (NP, Number Portability) and also claims the number of taking to change net, number portable, is meant the user of a tame telecommunications operator, need not to change the telephone number of oneself, just can transfer the user of another operator of family to, and enjoy the service that it provides.Along with the development of number portability service, various numbers occurred and carried technology.

At the short-message system of short messaging gateway intercommunication, can't directly visit between the operator client database.Provided a kind of number in the correlation technique and carried attaching position register NPHLR solution, the Message Processing flow process of this scheme comprises as shown in Figure 1: caller A1 place MSC-A sends to short message the sms center of caller A1 ownership; Caller A1 ownership sms center SMSC-A judges Mobile Subscriber International ISDN Number (Mobile Subscriber International ISDN number) the ownership Home Network of called A1, sends SRI_FOR_SM message to the former ownership of called B1 HLR_A; The former ownership of called B1 HLR-A issues the specific GT number (global title) of the current subscription network correspondence of B1 by SRI_for_SM_ack the sms center SMSC_A of caller A1 ownership; Caller A1 ownership SMSC_A corresponds to respective operator according to specific GT sign indicating number, and destination Mobile Station International ISDN Number is added RN (distant-end node symbol), and message is sent to Home Network Interworking gateway SMSGW_A according to the internetwork message flow process; SMSGW_A is with the SMSGW_B of forwards to the current subscription network of called B1; SMSGW_B is issued to the SMSC_B of the current subscription network of B1 with message, and SMSC_B carries out follow-up issuing according to this network information and is delivered to called B1.

The inventor finds that above-mentioned correlation technique is just carried the solution of visit at the local network number of short message, does not realize the cross-region visit but be suitable for.Because the difference of different regions network operation environment does not especially support that on a ground number carries, and another ground is when supporting situation that number carries, and above-mentioned correlation technique must be transformed the sms center of non-number carrier area, Short Message Service Gateway etc.Do not support number to carry with the strange land and be example that when SMSGW_A sent to SMSGW_B with the destination Mobile Station International ISDN Number that has added RN, therefore SMSGW_B can't resolve this message because do not support number to carry, thereby caused message to send mistake.And if want to address the above problem, must sms center, the Short Message Service Gateway of not supporting number to carry ground be transformed in a large number, make it can correctly receive and resolve the message of supporting that number sends with carrying.Yet, big to retrofit work amounts such as the sms center of non-number carrier area, Short Message Service Gateway, the transformation process complexity, cost is higher, is unfavorable for that Service Dialing Numbers carries service operation and carries out.

Summary of the invention

Step S202: the called SMSC of short message service center receives and sends to the short message that the called number that number carries takes place;

Step S204: called SMSC sends to number with short message and carries the NPMSC of mobile switching centre;

In this step, called SMSC can obtain the address of NPMSC from attaching position register HLR, short message is sent to the NPMSC of this address.

Step S206:NPMSC sends to called number with short message.

In the correlation technique, when realizing that the cross-region access number carries the user, need transform each sms center of existing network, Short Message Service Gateway etc., the retrofit work amount is big, transformation process is complicated, cost is high.Pass through present embodiment, in existing network, be provided with independently to check numbers and carry the NPMSC that the user carries out unified management, make called SMSC when the called subscriber number takes place is carried, directly short message is sent to NPMSC, carry out subsequent treatment by NPMSC again, thereby need not transform called SMSC of short message service center and short messaging gateway etc., can realize called number is carried user's visit, reduce system and realized cost.

With reference to Fig. 3, show the flow chart of steps of carrying implementation method according to the another kind of number of short message of the embodiment of the invention, may further comprise the steps:

Step S302: called SMSC receives the short message that sends to called number;

Step S304: called SMSC inquires about called positional information to called attaching position register HLR, and HLR judges whether called number number takes place carry, if, execution in step S306, if not, execution in step S312;

The NPMSC address that step S306:HLR returns called analog position (is the address of the MSC of unified management ported subscriber, rather than the direct MSC address of called number), called SMSC continues according to normal signaling process the NPMSC of short message issuing to analog position;

Called SMSC directly sends to short message corresponding NPMSC by obtain the NPMSC address from HLR, has significantly reduced the system searching NPMSC time, has improved system effectiveness.

After step S308:NPMSC receives short message, carry database NPDB according to the called number enquiry number, obtain the current signatory network distant-end node RN sign of called number, and, be forwarded to the short message intercommunication gateway SMSGW of this operator after adding the RN sign before the called number of short message;

Wherein NPDB can be provided with separately, also can be arranged among the NPMSC.

By NPDB, NPMSC can efficiently find the RN sign of called number correspondence apace, and by the RN sign, NPMSC directly sends to short message corresponding SMSGW, thereby has effectively improved SMSGW accurate positioning and system's execution efficient.

Step S310: after the SMSGW of this operator receives the short message that carries the RN sign, identify the SMSGW of short message according to RN through the current signatory carrier network of called number, be forwarded to the current signatory SMSC of called number and issue, finish the short message transmission flow;

Step S312: when called SMSC when called attaching position register HLR inquires about called positional information, do not carry if number takes place called number, called HLR is returned called number actual position MSC address (being the address of the direct MSC of called number), called SMSC with the MSC of short message issuing to actual position, finishes the short message transmission flow according to normal flow.

Need to prove that in the said process, if called SMSC and called HLR strange land, the direct cross-region visit of so called SMSC called HLR is carried out place information inquiry.Similarly, HLR returns the MSC address of actual position or analog position to the called SMSC in strange land according to the situation of carrying of called number.

Carry flow process corresponding to above-mentioned number, user that number carries is being taken place when bringing in, the SMSGW of current signatory carrier network is delivered to short message according to the RN sign of short message the SMSC of this RN sign indication; After this SMSC receives short message, remove RN sign wherein, carry NPHLR or HLR sends query requests (wherein according to the Home Network flow process to number, NPHLR is as HLR and the mobility data management of bringing the user in, in network, be in par with the HLR of existing network, after external user was brought present networks in, for the SMSC query messages, NPHLR returned real MSC address); NPHLR returns to this SMSC and carries the response message that this brings the MSC address of user's actual position in; After SMSC received this response message, the MSC that directly short message is delivered to actual position issued.Wherein, the HLR of NPHLR and existing network can close and establish, and also NPHLR can be provided with separately, NPHLR is set separately helps reducing transformation and influence to existing network.
