Description

A kind of method that on fixed intelligent network, realizes mobile intelligent service

Technical field

The present invention relates to the communications field, relate 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 switch and SSP functional unification.And overlay network is that switch and SSP function are independent, the shared SSP 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, 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 service control node SCP.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 according to the gsmSCP address that the prepaid user contracts, is triggered to gsmSCP request indication.

(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 IN 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, operator's 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.

Summary of the invention

The purpose of this patent is exactly on the basis that does not as far as possible increase the investment of user's intelligent network, relies on the existing intelligent equipment of user, provides a kind of feasible IN service solution.For this reason, the present invention adopts following scheme:

Embodiment

Below in conjunction with Figure of description the specific embodiment of the present invention is described.

The purpose of this programme is exactly not increase the mobile intelligent net investment, relies on to realize mobile intelligent service on the existing intelligent equipment of the user basis and do not need to increase big investment, and this intelligent network can be fixed intelligent network or the intelligent network that moves other standard.

The present invention increases the user intelligent service sign in the user data of HLR, with the IN service attribute of identifying user, when the user initiates the IN service request, this attribute is issued to MSC/VLA, identify by this and to indicate the identification intelligent business, finish the user intelligent service request.This user intelligent service sign is that the standby parameter in the user data that utilizes among the HLR realizes.Because the user signing contract information of HLR takes the form of an array; Each bar record in this array refers to all information of a user, and user's information is that each data item is formed in the array, and the IN service sign that adopts among the present invention is exactly a data item in the record.

Among the present invention, need do some settings to relevant network entity, specific as follows:

Modification to HLR:

Utilize the standby parameter in the user data among the HLR, the IN service attribute of identifying user.This parameter by the position more new technological process be issued to MSC/VLR.

Modification to MSC/VLR:

MSC reads the IN service attribute-bit, and according to the first conversion of the IN service sign number of carrying out, former called before the increase access code, be routed to tandem exchange, gateway exchange.

Data configuration to SSP:

SSP increases a data configuration, the mapping table of access code number and service key Service_key/SCP address.Online SSP supports target network and overlay network mode simultaneously at present, so support this data configuration.

Modification to SCP:

Increase business logic software, in existing standard SCP design, this software can on-line loaded.What the function of this business logic software and main flow be, is according to service key, and the account balance of inquiring user is if remaining sum greater than lower limit, then according to the rate of this time calling, is deducted corresponding cost.

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 request of the current position 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 the route prefix before called number, the existing intelligent network SSP 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 corresponding SSP according to this access code.

SSP finds corresponding service key and SCP address according to access code, 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, and the called route prefix that is triggered to SSP is R1, 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, configuration R1 is to the route of SSP in the data configuration of MSC;

3, SSP obtains corresponding Service-key, SCP address according to R1, 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, begins to charge;

4, SCP returns Continue/Connect.

5, the calling/called information that returns according to Connect of SSP 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, so Subscriber Number need identify the user roaming has taken place when delivering to SSP and SCP, as shown in Figure 7, mainly may further comprise the steps:

1, MSC analyzes and draws, if 0755 user A roams into 0754, the calling number that at this moment sends to SSP and SCP will be changed into 07540755A, and called number is R10755B.

2, SSP obtains corresponding Service-key and SCP address according to R1, initiates the IN service trigger request, comprising calling number 07540755A and called number 0755B.

3, the service logic analysis of SCP draws, and the user of 0755A is roaming into the calling that is initiated to 0755B after 0754, and SCP carries out correct charging, comprises roaming charges and call rate.

4, after SSP received that SCP returns the Continue/Connect indication, SSP called out according to the numbers of calling and called parties that SCP returns in the Connnect message, and SCP is transformed to 0755A-0755B, the same normal call of follow-up flow process.

In this case, roamer's number need not change to 07550755A-＞0755B, shows it is that 0755 user A is initiated to 0755 calling in this locality.

Embodiment 3: same MSC is connected to different SSP

The demand of the shared MSC of a plurality of local networks occurred at present on market, and the situation of the SSP of oneself is arranged again in each local network, the user who wishes local network converges the SSP that ties this locality and carries out intelligent trigger.

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 route access code R1, R2, R3 etc. respectively according to calling subscriber's different area codes, is routed to different SSP, 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 same SSP:

Different MSC increase identical or different route prefix and are routed to same SSP according to demand.For SSP, different route prefixes can be distinguished corresponding different service key and SCP address, prepayment service is triggered to different SCP, or is triggered to a unified SCP according to the different different charging logics of service key operation, embodies the rate variance between different local networks.

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: different SSP is connected to same SCP:

This does not have problem yet, and route prefix and service key, SCP have corresponding relation, and SSP can carry out correct prepayment service according to SCP address to be triggered.

SCP carries out correct charging according to caller and called number that SSP sends.Charging way is with present mobile network.

This 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 called route prefix that Shanghai (area code 020) is triggered to SSP.

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, and route is routed to SSP and carries out intelligent trigger, and the parameter of band has: original called party number 0200755B, called number R1020C, calling subscriber 0755A etc.

5, SSP receives after the calling, obtain ServiceKey X1 according to R1, identifying this is a called triggering prepaid user, obtain user's SCP address according to ServiceKey, initiate IDP message to SCP, 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, calls corresponding processing logic, checks original called party number, finds that this user who is the prepaid user of a 0755B has roamed into 020, one 0755A makes a call to him, and SCP returns SSP after the party B-subscriber is chargeed.

7, SSP receives after the calling, 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 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 to 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, 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 the modification called number is 0200755B, and identifying user 0755B has roamed into 020, and the front increases route access code R1 then, continues call proceeding to SSP.

5, SSP receives after the calling, obtains ServiceKey X1 according to R1, and identifying this is a prepaid user, obtains user's SCP address according to ServiceKey, initiates IDP message to SCP, and calling number is 0755A in the message, and called number is X10200755B.

6, SCP receives after the message, checks numbers of calling and called parties, finds that this user who is the prepaid user of a 0755B has roamed into 020, one 0755A makes a call to him, and SCP returns SSP after the party B-subscriber is chargeed, and the called number number of changing is 0755B.

7, SSP receives after the calling, 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.

If the called subscriber does not roam, at this time needing to revise called number is 07550755B, and SSP is triggered and smart charge.

This programme is not increasing mobile intelligent net investment, relies on to realize IN service on user's existing fixed intelligent equipment basis and do not need to increase big investment.Its investment is little, can make full use of the investment of existing intelligent network, carries out prepayment service rapidly.

The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claims.
