Technical field
The present invention relates to the communications field, relates in particular to the IN service field.
Technical background
IN service (Intelligent Network Service) is meant the business that service is provided for all communication networks by intelligent network.At present widespread usage has prepayment service, card number service, a virtual private network service etc.
China mobile network mainly contains two kinds of standards at present, a kind of is widely used GSM standard in Europe, all there are the network of this kind standard in China Mobile and CHINAUNICOM, a kind of is that CHINAUNICOM is greatly developing the mobile network based on the CDMA standard at present in the widely used CDMA standard in North America and East Asia.Realize that in the mobile network prepayment service need increase intelligent equipment, provide this function by intelligent equipment, the intelligent network standard of using in the GSM standard is the CAMEL standards system of ETSI definition, he adopts is ITU-T at the standard CS-1 distributed architecture of series definition Q.12XX, and the prepayment service ability defines in CS-1.The intelligent network standard of using in the CDMA standard is called WIN, and what it adopted is the CS-2 distributed architecture of IUT_T.In order to expand easily, ANSI/TIA/EIA has carried out certain expansion to signaling message and the signaling process of former ANSI41D, on original basis, defined a series of wireless intelligent networks (WIN) agreement again, mainly comprise IS771, PN4287 and PN4289, and these agreements will be integrated among the ANSI41E.ANSI41E will become a complete core network protocol based on intelligent network.Typical intelligent net system as shown in Figure 1, comprise following network entity: service creation environment, Service Switching Point, service management point, ip intelligent peripherals, SMAP, service data point and service control point, wherein service control point plays professional control, is the core of intelligent network.
Present intelligent network mainly contains target network and two kinds of implementations of overlay network, and target network is the implementation of SSP functional unification in switch and the fixed intelligent network.And overlay network is that the SSP function is independent in switch and the fixed intelligent network, SSP in the shared fixed intelligent network of one or more switch, and generally the mode by number segment realizes triggering.At present the cdma network of China Mobile's GSM network and UNICOM substantially all is a target network, and in the long run, target network also is the development trend of intelligent network, so we this paper mainly is that example describes with the target network, but conclusion is equally applicable to overlay network.
Realizing the operation flow of intelligence on the target network, is by SSP reporting service key in the fixed intelligent network, and triggering intelligent call flow process realizes.
If the user is signed up as intelligent subscriber, then among the user signing contract information O-CSI and T-CSI in HLR, identify user's service key (as pre-payment), the address of SCP in the business control nodes fixed intelligent network.Mobile initiation (MO) intelligent call and Mobile Termination (MT) intelligent call that provide the GSM network below are the realization flow of example explanation IN service.
As shown in Figure 2, be in the prior art, intelligent subscriber initiates the triggering schematic diagram that (MO) calls out, and may further comprise the steps:
When (1) upgrading in the position or O-CSI when changing, O-CSI information is sent among the VLR of visit office and stores;
(2) MSC receives the setup requests of base station system (BSS), to the VLR searching user's information;
(3) MSC comprises O-CSI information from VLR user profile, choose the O-CSI that satisfies the DP standard after, the MSC current calling that suspends, SCP address in the gsm fixed intelligent network of contracting according to the prepaid user is triggered to SCP request indication in the gsm fixed intelligent network.
(4) gsmSCF starts the prepayment service logic, carried out the charging flow of pre-payment after, indication gsmSSF continues;
(5) gsmSSF receives the indication of gsmSCF, finishes call setup procedure according to the routing iinformation of gsmSCF indication.
As shown in Figure 3, be that the user stops the triggering schematic diagram that (MT) calls out, may further comprise the steps:
(1) GMSC receives the call request of going into of the office that makes a start;
(2) GMSC is to called Home Location Registry place (HLR) inquiry routing iinformation;
(3) HLR finds to be the prepaid user, to return called subscriber's T-CSI information called;
(4) GMSC receives the T-CSI information that HLR returns, and shows that this calling is an intelligent call.The GMSC current calling that suspends, gsmSSF is according to gsmSCF Address in the T-CSI information and prepayment service key, to suitable gsmSCF request indication;
(5) gsmSCF starts service logic, carried out the charging flow of pre-payment after, indication gsmSSF complete connection;
(6) GMSC is for the second time to called HLR request route information;
(7) HLR returns roaming number;
(8) GMSC finishes call setup procedure according to the roaming number that returns.
Realize that at present mobile intelligent service needs the support of mobile intelligent net, but on the market of fixed network development Personal Handyphone System(PHS), the investment of a local network construction Personal Handyphone System(PHS) intelligent network is very big, and operator's initial stage initial stage does not wish to build intelligent network, can carry out prepayment service again.
The topmost shortcoming of prior art scheme is to need to increase the investment of building intelligent network, and comparatively speaking, the investment of intelligent network is still bigger.The increase of investment causes the increase of cost and business to be difficult to quick popularization.Though it is abundant professional flexibly that intelligent network can provide, and in the area that some hope are carried out mobile service among a small circle or only are desirable to provide prepayment service, do not wish to realize this business by the intelligent network of costliness.

Based on above-mentioned setting, the present invention can specifically may further comprise the steps:
A, user initiate location registers;
This step can be that the user comes the new band of position or periodic location update time when arriving, and promptly user's relevant location information changes or artificially sets update condition and come temporarily, initiates location registers.
B, MSC initiate to upgrade the position requests at the current place of user to HLR;
C, HLR home position register response comprise the IN service sign that the user increases newly in this response;
D, MSC increase access code before called number, SSP in the existing intelligent network fixed intelligent network of operator is tied in its remittance;
Here, MSC is to user's home position register response, and user data inserts VLR, comprising the IN service sign that increases newly;
The MSC beginning is exhaled the inspection user data, finds this user's IN service, and the MSC sign indicating number increases an access code according to the IN service attribute before called number, be routed to SSP in the corresponding fixed intelligent network according to this access code.
SSP finds SCP address in corresponding service key and the fixed intelligent network according to access code in the fixed intelligent network, carries out intelligent trigger.
See several specific embodiments below:
Embodiment 1: the intelligent subscriber ownership place beginning exhales
Suppose user's (area code in Shenzhen is 0755) in two Shenzhen, rear subscriber number is A, and called number is B, is triggered to that the called access code of SSP is R1 in the fixed intelligent network, as shown in Figure 6, comprises following key step:
1, user A makes a call in Shenzhen, and caller here is with the IMSI sign, and is called with number B sign;
2, MSC obtains calling subscriber's number 0755A according to user data, check the IN service attribute of calling subscriber's data then, effective as the IN service attribute, add area code in the called number front, and according to the IN service attribute, increase access code R1 in the called number front, the route of configuration R1 SSP in the fixed intelligent network in the data configuration of MSC;
3, SSP obtains SCP address in corresponding Service-key, the fixed intelligent network according to R1 in the fixed intelligent network, initiates the IN service trigger request.Comprising calling number 0755A and called number 0755B.SCP knows it is customer call Shenzhen, Shenzhen user according to this in the fixed intelligent network, begins to charge;
4, SCP returns Continue/Connect in the fixed intelligent network.
5, the calling/called information that SSP returns according to Connect in the fixed intelligent network continues to call out with 0755A and 0755B.
Embodiment 2: the intelligent user roam ground beginning exhales
It is distinguishing that the ownership place beginning of this situation and front exhales, because the charge of user under the situation of roaming is different, therefore Subscriber Number is in delivering to fixed intelligent network in SSP and the fixed intelligent network in the SCP, need identify the user roaming has taken place, as shown in Figure 7, mainly may further comprise the steps:
1, MSC analyzes and to draw, if 0755 user A roams into 0754, at this moment sends in the fixed intelligent network among the SSP and fixed intelligent network the calling number of SCP and will change into 07540755A, and called number is R10755B.
2, SSP obtains SCP address in corresponding Service-key and the fixed intelligent network according to R1 in the fixed intelligent network, initiates the IN service trigger request, comprising calling number 07540755A and called number 0755B.
3, the service logic analysis of SCP draws in the fixed intelligent network, and the user of 0755A is roaming into the calling that is initiated to 0755B after 0754, and SCP carries out correct charging in the fixed intelligent network, comprises roaming charges and call rate.
4, after SSP receives that SCP returns the Continue/Connect indication in the fixed intelligent network in the fixed intelligent network, SSP calls out according to the numbers of calling and called parties that SCP in the fixed intelligent network returns in the Connnect message in the fixed intelligent network, SCP is transformed to 0755A-0755B in the fixed intelligent network, the same normal call of follow-up flow process.
In this case, roamer's number need not change to 07550755A-〉0755B, show it is that 0755 user A is initiated to 0755 calling in this locality.
Embodiment 3: same MSC is connected to SSP in the different fixed intelligent networks
The demand of the shared MSC of a plurality of local networks occurred at present on market, and the situation of SSP in oneself the fixed intelligent network is arranged again in each local network, the user who wishes local network converges that SSP carries out intelligent trigger in the fixed intelligent network of tying this locality.
The user is when calling out, and MSC will obtain the current visit ground of user according to different lane place, can obtain caller and called number with area code.This demand solves in the roaming scheme based on the sub-district, and we suppose that herein this demand satisfies.
MSC can add different access code R1, R2, R3 etc. respectively according to calling subscriber's different area codes, is routed to SSP in the different fixed intelligent networks, as shown in Figure 8, is its connection diagram.
Under the situation of roaming, Subscriber Number itself is 0755A, and MSC initiates professional lane place according to the user, increases the area code of current place local network.Calling number is revised as the form of 07540755A, can support the charging of user's roaming condition, increases different access code R1, R2, R3 etc. according to the IN service attribute before called number equally.Mainly contain following several situation:
Embodiment 4: different MSC is connected to SSP in the same fixed intelligent network
Different MSC increase identical or different access code and are routed to SSP in the same fixed intelligent network according to demand.For SSP in the fixed intelligent network, different access codes can be distinguished SCP address in corresponding different service keys and the fixed intelligent network, prepayment service is triggered to SCP in the different fixed intelligent networks, or be triggered to that SCP embodies the rate variance between different local networks according to the different different charging logics of service key operation in unified the fixed intelligent network.
The situation of user's roaming, the number that MSC sends comprises two area codes, and one is user visiting ground, and one is user ascription area (being included in the Subscriber Number, as 07540755A), just can correctly support user's roaming.
Embodiment 5: SSP is connected to SCP in the same fixed intelligent network in the different fixed intelligent networks:
This does not have problem yet, and SCP has corresponding relation in access code and service key, the fixed intelligent network, and SSP can carry out correct prepayment service triggering according to SCP address in the fixed intelligent network in the fixed intelligent network.
SCP carries out correct charging according to caller and called number that SSP in the fixed intelligent network sends in the fixed intelligent network.Charging way is with present mobile network.
It is the call flow of a standard.Process slightly later on.
Embodiment 6: the mobile intelligent subscriber ownership place stops (MT) and calls out
Suppose user's (area code in Shenzhen is 0755) in two Shenzhen, rear subscriber number is A, and called number is B, and it is R1 that the called subscriber roams into the access code that Shanghai (area code 020) is triggered to SSP in the fixed intelligent network.：
The intelligent dialing call flow referring to the description of front, omits herein.
In this case, called intelligent call flow process as shown in Figure 9, it mainly comprises:
1, call proceeding is to gateway exchange MSC/GMSC.
2, gateway exchange MSC/GMSC receives calling, initiates to get roaming number to called subscriber HLR.
3, HLR finds that the user is intelligent subscriber, obtains user's roaming number, and HLR returns and gets roaming number and IN service sign then.
4, GMSC finds that the user is the prepaid user, judges current position in the roaming place, is routed to that SSP carries out intelligent trigger in the fixed intelligent network, and the parameter of band has: original called party number 0200755B, called number R1020C, calling subscriber 0755A etc.
5, SSP receives after the calling in the fixed intelligent network, obtain ServiceKey X1 according to R1, identifying this is a called triggering prepaid user, obtain SCP address in user's the fixed intelligent network according to ServiceKey, SCP initiates IDP message in fixed intelligent network, calling number is 0755A in the message, and original called party number is 0200755B, and called number is X1020C.
6, SCP receives after the message in the fixed intelligent network, call corresponding processing logic, check original called party number, find that this is that the prepaid user of a 0755B has roamed into 020, the user of a 0755A makes a call to him, after SCP charges to the party B-subscriber in the fixed intelligent network, return SSP in the fixed intelligent network.
7, SSP receives after the calling in the fixed intelligent network, and caller at this moment is 0755A, and called is 020C, continues to make a call, and call proceeding is to the roaming place MSC at user B place.
If the called subscriber does not roam, at this time needing original called party number is 07550755B, and SSP in the fixed intelligent network is triggered and smart charge.
Illustrate: gateway exchange GMSC gets roaming number, after HLR detects called intelligent trigger attribute, returns roaming number and intelligent quilt triggering attribute; When being routed in the fixed intelligent network SSP, have former called (roaming place area code+called number), called number (roaming number) in the message; In the processing logic of SCP, know it is called triggering in the fixed intelligent network, charge at original called party number.Other is handled with the intelligent dialing Business Processing.
Called call flow mainly comprises as shown in figure 10:
All devices wherein all is positioned at called subscriber's ownership place, and call flow is as follows:
1, TS receives the calling next from the other places, checks that calling number is 0755A, and called number is 0755B, and 0755B is the mobile subscriber, and call proceeding is to local mobile gateway office.
2, mobile GMSC receives calling, initiates to get roaming number to called subscriber HLR.
3, HLR finds that the user is the prepaid user, checks the current visit of user ground, and MSCID is changed to area code 020, local identifying user was got area code by 0755A (the perhaps IMSI of A), and HLR returns the response message of getting roaming number then, and identifying user is the prepaid user, 020 of current roaming
4, GMSC finds that the user is the prepaid user, and current location is 020, and modifications called number is 0200755B, and identifying user 0755B has roamed into 020, and the front increases access code R1 then, continuation call proceeding SSP in the fixed intelligent network.
5, SSP receives after the calling in the fixed intelligent network, obtain ServiceKey X1 according to R1, identifying this is a prepaid user, obtain SCP address in user's the fixed intelligent network according to ServiceKey, SCP initiates IDP message in fixed intelligent network, calling number is 0755A in the message, and called number is X10200755B.
6, SCP receives after the message in the fixed intelligent network, check numbers of calling and called parties, find that this is that the prepaid user of a 0755B has roamed into 020, the user of a 0755A makes a call to him, after SCP charges to the party B-subscriber in the fixed intelligent network, return SSP in the fixed intelligent network, the called number number of changing is 0755B.
7, SSP receives after the calling in the fixed intelligent network, and caller at this moment is 0755A, and called is 0755B, continues to make a call, and call proceeding is to gateway exchange.
8, GMSC finds that this is a mobile number after receiving and calling out, and initiates to get roaming number once more.
9, HLR receives and gets after the roaming number request, checks user data, finds that the user was once got roaming number one time by same user, has returned an area code, and current HLR initiates real get the roaming number operation and obtain number 020C and return GMSC.
10, GMSC continues to call out 020C, at this moment has been the call flow of a standard.Process slightly later on.
