Description

In mobile intelligent net, realize the method and system of IN service

Technical field

The present invention relates to moving communicating field, relate in particular to the method and system that in mobile intelligent net, realize IN service.

Background technology

At present, many operators wish to provide intelligent network business on existing global system for mobile communications (GSM) or code division multiple access (CDMA) network, but the Standard IN service needed network equipment possesses the ability of supporting intelligent network, therefore this be difficult to realize with regard to the upgrading that relates to the network equipment and the problem of producer's degree of support in practice.At present, often adopt the mode of non-standard intelligent network (also being overlay network) that IN service is provided.

The scheme of existing overlay network is the stand alone exchange that stack one deck is supported the intelligent network ability on network, becomes independent SSP.Consult shown in Figure 1ly, be the networking structure schematic diagram of overlay network, its principle is that MSC is routed to independent SSP to the calling of intelligent subscriber and gets on, and triggers IN service on the SCP by the SSP that supports the intelligent network ability, provides service to the user.

When using the scheme of overlay network, the judgement user is that the method for intelligent subscriber has two kinds:

Method one: intelligent subscriber changes original number, adopts new number segment, to distinguish with the old user; On MSC, judge during calling, get on if special number Duan Ze routes calls to SSP.

Method two: adopt the special access code mode, when the user wishes to open IN service, need at first import access code, MSC judges when being special access code, then routes calls to SSP and get on.

Judge in the prior art that the user is that two kinds of methods of intelligent subscriber exist following defective: require the number of intelligent subscriber must adopt special number segment in the method one, original user must change number just can become intelligent subscriber, method two must add access code, inconvenient user's use when requiring intelligent subscriber to call out.

Summary of the invention

The present invention is directed to the deficiencies in the prior art, propose a kind of method and system that in mobile intelligent net, realize IN service, to solve the problem that adopts special number section or access code mode to bring inconvenience to the user.

For this reason, the present invention adopts following scheme:

A kind of mobile intelligent net system, include Service Control Point, Service Switching Point, attaching position register (HLR), mobile switching centre (MSC), short message service center (SMSC) and STP, this STP has signaling channel respectively and between SCP, SSP, MSC, HLR and the SMSC; Described SCP is used in the pseudo-number of trigger intelligent business and the corresponding relation between pseudo-number of preservation and the true number of user for the intelligent subscriber branch, and registers pseudo-number on MSC; Described STP tackles between MSC and HLR and the SMSC and the mutual signaling between SSP and the HLR, and cooperates pseudo-number of the user who finishes in the signaling and true number translated with SCP, the intelligent service logic when described SSP detects user's puppet number on the triggering SCP.

This kind realizes that in mobile intelligent net the method for IN service comprises the steps:

Allocation step is used to intelligent subscriber to distribute pseudo-number, and sets up the corresponding relation of true number of user and pseudo-number and register described pseudo-number at MSC on SCP;

The interception step is used for all the mutual signaling catchings between MSC and HLR and the SMSC and between SSP and the HLR to SCP;

Analytical procedure is used to analyze the signaling that whether needs to handle interception, when determining to change the Subscriber Number in the signaling, is true number with the pseudo-number translated in the signaling or is pseudo-number with the true number translated in the signaling;

Trigger step, when MSC detects the pseudo-number that participates in the user that calls out, route the call to SSP, trigger IN service on the SCP according to this puppet number by SSP; Perhaps trigger intelligent business when SCP determines the short-message users that is blocked for intelligent subscriber;

Treatment step is finished IN service by SCP and is handled, and proceeds corresponding subsequent processing according to result.

The present invention compared with prior art has following advantage:

1. adopt this method to substitute the true number of irregular user, register, route, search work such as roaming number with pseudo-number clocklike.

2. adopt this method on non-standard intelligent network, to carry out IN service, need not the user and change number, also need not the user and dial access code Any user.

3. adopt this method on the basis of existing business, conveniently to carry out other IN service.

Embodiment

Consult shown in Figure 2ly, intelligent net system of the present invention comprises Service Control Point, Service Switching Point, attaching position register (HLR), mobile switching centre (MSC) and short message service center (SMSC); SCP is used in the pseudo-number of trigger intelligent business and the corresponding relation between pseudo-number of preservation and the true number of user for the intelligent subscriber branch, and registers pseudo-number on MSC.SCP also is used to tackle between MSC and HLR and the SMSC and the mutual signaling between SSP and the HLR, and finishes pseudo-number of user and true number translated in the signaling.Described SSP triggers the intelligent service logic on the SCP when detecting user's puppet number.

Consult shown in Figure 3ly, as the SCP of interception signaling, also can realize among Fig. 2 with the STP that strengthens, Business Processing still realizes that by SCP former SCP is divided into two entities, and STP is used for signaling catching, SCP is used for Business Processing, and STP shares or data of opening an account of the intelligent subscriber on the SCP synchronously.

Pseudo-in the present embodiment number structure is: route code+SCP coding+MSC place message area sign indicating number+arbitrary numbers, this number total length needs the restriction less than MSC.Certainly also can adopt other forms of coding, its principle is to distinguish SCP and MSC.

Below mainly realization of the present invention is elaborated with networking structure shown in Figure 2.

Consult shown in Figure 4ly, in the process of whole service flow process, the process of intelligent subscriber registration and position renewal is as follows:

Step 1: register to HLR when mobile subscriber's start or position are upgraded, send the location registration signal IMSI of MSISDN1 by MSICa to SCP;

Step 2:SCP judges after this signaling the location registration signal IMSI to HLR transparent transmission MSISDN1;

Step 3:HLR returns user's phone number MSISDN1, is blocked during signaling process SCP;

Step 4:SCP judges whether this phone number MSISDN1 is intelligent subscriber, if intelligent subscriber then carries out number translated to it, promptly revising MSISDN1 is a pseudo-number S_ISDN1, and the relation of MSISDN1 and S_ISDN1 is preserved;

Pseudo-number S_ISDN1 after step 5:SCP will change passes to MSC, finishes the location registers response of HLR to MSCa.IMSI and pseudo-number are set up corresponding relation on MSC, and MSC is used as right number to pseudo-number and uses.

Consult shown in Figure 5, when caller is intelligent subscriber, called when being domestic consumer or his network users business processing flow as follows:

Step 1: intelligent subscriber MSISDN1 makes a call, and MSCa is routed to SSP to call request according to the route code RN among the pseudo-number S_ISDN1 of intelligent subscriber registration;

Step 2:SSP is according to the coding of the SCP among S_ISDN1 trigger intelligent business;

Step 3:SCP carries out number translated according to MSISDN1 that preserves and the relation of S_ISDN1, is about to pseudo-number S_ISDN1 and is converted to true number MSISDN1;

Step 4:SCP finds user data and carries out the processing of IN service according to user's true number;

Step 5:SCP sends true number MSISDN1 to SSP, and indication SSP connects calling.

When being intelligent subscriber, MSC or SSP do not carry the supression parameter in searching in the called route signaling of initiating for the first time when called, and it is directly to return MSC or SSP behind the pseudo-number with trigger intelligent business with called subscriber's true number translated that this signaling is blocked back SCP.The supression parameter is carried in searching in the called route signaling that SSP initiates after trigger intelligent business, and SCP this signaling of transparent transmission after detecting this supression parameter arrives HLR.

Consult shown in Figure 6ly, when caller is domestic consumer or his network users, called called flow is from (G) MSCa during for intelligent subscriber, and business processing flow is as follows:

Step 1:(G) MSCa initiates to search the signaling of called route, and this signaling is tackled by SCP;

Step 2:SCP judges whether MSISDN2 is intelligent subscriber, if intelligent subscriber then SCP directly return called pseudo-number S_ISDN2 to (G) MSCa;

Step 3:(G) MSCa is routed to SSP to call request according to the route code RN among the pseudo-number S_ISDN2,

Step 4:SSP encodes to the SCP trigger intelligent business according to the SCP among the pseudo-number S_ISDN2;

Step 5:SCP handles IN service and pseudo-number S_ISDN2 is become true number MSISDN2;

Step 6:SCP is handed down to SSP with true number MSISDN2;

Step 7:SSP initiates called routing inquiry to HLR, and restrains CSI parameter (being different triggers among the CDMA) with going up;

Step 8:SCP interception routing inquiry signaling and detect wherein CSI parameter after, this signaling is transparent to HLR;

Step 9:HLR sends the signaling of inquiring about roaming number to MSCb, and this signaling is tackled by SCP;

Step 10:SCP converts called true number MSISDN2 to pseudo-number S_ISDN2;

Step 11:SCP sends the signaling of inquiry roaming number to MSCb with pseudo-number;

Step 12:MSCb returns according to pseudo-number assignment roaming number MSRN2 (in the CDMA net is TLDN, down together), is tackled by SCP once more;

Step 13:SCP becomes pseudo-number S_ISDN2 again called true number MSISDN2;

Step 14:SCP returns roaming number MSRN2 and gives HLR;

Step 15,16:HLR return MSRN2 again through SCP and give SSP;

Step 17:SSP is routed to MSCb with call request.

Consult shown in Figure 7ly, when calling and called all were intelligent subscriber, called flow was from SSP.Since the pseudo-number that MSC detects caller then with call proceeding to SSP, trigger IN service on the SCP by SSP, finish the true number of caller is returned to SSP after the IN service of caller handled at SCP, so called flow from SSP, its flow process is as follows:

Step 1:SSP initiates to search the signaling of called route, and this signaling is tackled by SCP;

Step 2:SCP judges whether MSISDN2 is intelligent subscriber, if intelligent subscriber then SCP directly return called pseudo-number S_ISDN2 to SSP;

Step 3:SSP encodes to the SCP trigger intelligent business according to the SCP among the pseudo-number S_ISDN2;

Step 4:SCP handles IN service and pseudo-number S_ISDN2 is become true number MSISDN2;

Step 5:SCP is handed down to SSP with true number MSISDN2;

Step 6:SSP initiates called routing inquiry to HLR, and band is restrained CSI parameter (being different triggers among the CDMA);

Step 7:SCP interception routing inquiry signaling and detect wherein supression CSI parameter after, this signaling is transparent to HLR;

Step 8:HLR sends the signaling of inquiring about roaming number to MSCb, and this signaling is tackled by SCP;

Step 9:SCP converts called true number MSISDN2 to pseudo-number S_ISDN2;

Step 10:SCP sends the signaling of inquiry roaming number to MSCb with pseudo-number;

Step 11:MSCb returns according to pseudo-number assignment roaming number MSRN2 (in the CDMA net is TLDN, down together), is tackled by SCP once more;

Step 12:SCP becomes pseudo-number S_ISDN2 again called true number MSISDN2;

Step 13:SCP returns roaming number MSRN2 and gives HLR;

Step 14,15:HLR return MSRN2 again through SCP and give SSP;

Step 16:SSP is routed to MSCb with call request.

Consult shown in Figure 8ly, the business processing flow when intelligent subscriber sends note is as follows:

Step 1: when the user sends note to SMSC by MSCa, tackled by SCP, that this moment, MSCa sent is pseudo-number S_ISDN1;

Step 2:SCP judges whether the user is intelligent subscriber, if intelligent subscriber, then the pseudo-number S_ISDN1 of conversion user is true number MSISDN1;

Step 3:SCP carries out IN service to be handled;

Step 4:SCP sends to sms center SMSC with true number MSISDN1 with note.

Consult shown in Figure 9ly, the business processing flow when intelligent subscriber receives note is as follows:

Step 1,2: sms center SMSC searches recipient's note route through SCP to HLR;

Step 3:HLR is tackled by SCP when MSCb returns recipient's note routing iinformation MSCbID;

Step 4:SCP judges whether the user is intelligent subscriber, if intelligent subscriber then carries out IN service and handles;

Step 5:SCP returns to sms center SMSC with recipient's routing iinformation MSCbID;

Step 6:SMSC sends note to MSCb and is tackled by SCP;

The true number MSISDN2 of step 7:SCP conversion user is pseudo-number S_ISDN2;

Step 8:SCP sends note to MSCb with pseudo-number S_ISDN2.
