Description

The intelligent network service

The application is that the application number submitted on December 16th, 2005 is dividing an application of 200580052316.4 one Chinese patent application.

Technical field

The present invention relates to be used to handle and relevant intelligent network service method and the Control Node of calling to the subscriber of mobile telecom network.

Background technology

In current telecommunication network technology such as GSM (global system for mobile communications), the intelligent network service is well-known.

The central unit of GSM server network subsystem is to move to serve switching center (MSC).It works to be similar to the switching node of PSTN or ISDN, and is provided for handling the required all functions of mobile subscriber in addition, upgrades, transfers and arrive roaming subscriber's calling route such as registration, authentication, position.These services are provided together with several functional entitys, and they have constituted core network subsystem together.Gateway MSC (GMSC) is provided to the connection of fixed network (such as PSTN or ISDN).Signaling between the functional entity in the core network subsystem is used Signaling System 7(SS-7), and Signaling System 7(SS-7) is used for the relaying signaling and is widely used at current public network in ISDN.

Attaching position register (HLR) and Visited Location Registor (VLR) provide calling route and the roaming capacity of GSM with MSC.HLR is included in all management information of each subscriber who registers in the corresponding GSM network, and the current location of this mobile radio station.The form of the signaling address of the VLR that the position of mobile radio station normally is associated with this mobile radio station.Say that logically HLR of each GSM network is although it can be implemented as distributed data base.

VLR be currently located at by in the geographic area of this VLR control and current each mobile radio station by this VLR service comprise for calling out control and the necessary selected management information from HLR of service of reservation being provided.Although each functional entity can be implemented as independently unit, current all switching equipment manufacturers realize VLR with MSC, and are corresponding with the geographic area that VLR is controlled by the geographic area of MSC control like this, thereby simplified required signaling.MSC does not comprise the information about specific mobile radio station; This information is stored in location register.

Next, typical incoming call foundation (Mobile terminating call (mobileterminating call)) in the GSM network will be described.

When the subscriber makes a call to mobile phone, it dials the telephone number that is associated with this telephone subscriber, promptly so-called mobile radio station ISDN (MSISDN) number, and this calling is routed to the gateway MSC of this mobile-phone carrier.Gateway is to be used to interconnect the node of two networks.Gateway realizes in MSC that usually MSC is called GMSC in this case.GMSC is as the inlet from the exterior portion of PSTN to provider network.

As stated, phone can freely roam among the carrier network or roaming partner's network on Anywhere, comprise other country.Therefore, first task of gateway MSC is to confirm that the current location of mobile phone is so that connect this calling.It accomplishes this point through consulting HLR, and HLR knows at this phone of this moment be associated with which Visited Location Registor (VLR) (if any) as stated.

When HLR receives this query messages, it determines whether route the call to another number (being called transfer) or should this calling be routed directly to the mobile radio station of being called out the subscriber.

If the owner of phone had before asked all incoming calls are transferred to another number, this supplemental services is also referred to as by the unconditional calling switching (CFU) of switching number (FTN), and this FTN is stored among the HLR so.If this situation returns FTN to this gateway MSC so that be routed to that destination immediately so.

If mobile radio station is current not to be associated with VLR (for example because phone shut down), HLR returns the number that is called calling not switchable (CFNR) number and gives GMSC so, and this calling is transferred to the there.Many operators can be set to this value the Voice Mailbox number of this phone automatically, and the caller can stay message like this.

At last, if HLR knows this phone within the compass of competency of specific VLR, it will be from temporary number of this VLR request, promptly so-called mobile radio station roaming number (MSRN) so.This number is relayed to GMSC, and GMSC uses it to route the call to another MSC that is called by visit MSC (VMSC).

When VMSC receives this calling, use MSRN in VLR, to seek the record of this phone.The band of position of this this phone of record identification.Paging is taken place in all mobile phone bars in this zone (mobile phone mast).When subscriber's mobile phone responded, this phone allocation really was returned to VMSC.VMSC is transferred to suitable telephone pole with calling subsequently, and this telephone rings.If the subscriber replys, create the voice pathway of getting back to the network that the people calls out through this VMSC and GMSC, and be general call subsequently.

Also possibly call out and do not replied.If the subscriber is being busy with another calling (and not using Call Waiting), VMSC routes the call to busy switching (CFB) number of calling out of predetermined chance so.Similarly, if the subscriber does not have answering call afterwards in a period of time (normally 30 seconds), VMSC routes the call to predetermined no-reply call switching (CFNRy) number so.Once more, operator can determine to give tacit consent to the Voice Mailbox that this value is set to this phone, so that the caller can stay message.

Intelligent Network is that the operator that makes with communication network coupling can adopt the network of the distinctive value-added service of operator (VAS).Increased intelligence resident in the switch through the intelligence from intelligent network, intelligence in the intelligent network is placed in the computer node that is distributed in the network everywhere.This provides more effectively to Virtual network operator and has developed, adopted and controlled service manner.New service can be incorporated in the communication network fast.In case introduce, service can easily customize to satisfy the demand of individual customer.

The IN service is provided by SCP (SCP) usually.SCP be with communication network in other node and entity control of communication computer.SCP comprises the service logic of one or more IN services, and the optional IN service subscription data that comprise, this subscription data allows SCP to carry out IN service, promptly special service execution to this subscriber according to subscriber's specific setting.When having set up calling, communication network can be inquired the instruction of SCP and this calling of Request Processing.For example, the translation that SCP is provided 800 number to arrive actual phone number by consulting, and be owner charging of this calling to this 800 number.SCP physically can with other components apart of intelligent network, perhaps can with these other combination of components in individual node.

In the GSM network, the IN service subscription information is stored in HLR.The information of resident two types among the HLR: (1) static subscriber information and (2) dynamic subscriber information.The latter for example need allow incoming call is routed to this mobile subscriber.HLR stores following information and other:

-international mobile subscriber identity (IMSI); The inside subscriber identity that only uses by this network;

-Mobile Subscriber International ISDN Number;

-VLR address;

-about the subscriber data of supplemental services.

The IN service can be divided into two kinds.Kind be included as and make a call (terminal makes a call-service that MOC) subscriber calls.These services are called the terminal and initiate (MO) service.An example of MO service is the outbound call shielding.

With initiating CAMEL subscription information (O-CSI) rubidium marking, this element is used in SCP sign special services each IN service subscriber in his HLR.Call out in case the subscriber starts MO, O-SCI starts the triggering of MOC service.In above-mentioned example, adopted CAMEL, it represents " customized application that is used for mobile network's enhancing logical ".CAMEL develops into the standard that is used to expand land-line IN telephone service, transfers such as Call Waiting with to the calling of gsm mobile telephone.

Another kind is included as the receipt of call (service that the subscriber of Mobile terminating call-MTC) calls.These services are called Mobile terminating call (mobile terminating, MT) service.The example of Mobile terminating call service is calling transfer service and personal greeting service (PGS).PGS is and the relevant service of roaming branch line (roaming leg).PGS makes and ought between GMSC and VMSC, (so-called roaming branch line) set up the signaling connection, shows personalized greeting to MPTY.Traditional alert tone (" jingle bell tone ") has been replaced in individualized greeting.Like this, the main foundation with the roaming branch line of individualized greeting is relevant; Have only when the roaming branch line set up and alarm the called party time jingle bell tone just become effective.Each IN service subscriber utilizes termination CAMEL subscription information (T-SCI) sign to come mark in his HLR, and this mark is used in SCP sign special services.This starts the triggering of MTC service during attempting subscriber's calling.

According to current techniques, Control Node can be inquired HLR so that obtain the instruction from HLR during MTC handles.Control Node can be GMSC.In response to the inquiry of Control Node, HLR can send and be used for called IN trigger message.The IN trigger message that between HLR and Control Node, exchanges is by standardization.For example, as in 3GPP TS 29.002 by 3GPP (third generation partner program) appointment, T-CSI is the called IN trigger message that is used for of GSM standardization.The IN trigger message comprise IN service the service keyword of the specific IN service in address and this SCP of sign of resident SCP.

According to be subscriber's appointment in the IN trigger message, Control Node uses this IN trigger message to call the IN service among the SCP.In response to service call, the result that SCP depends on this service execution sends instruction to Control Node, for example continues to set up calling or called.It is single the calling that a MTC handles the IN service that current network is set to usually.But recent development shows, during called processing, need call two or more IN services.

Patent application WO00/25528 discloses the service interaction management device that in SCP, comprises.The task of service interaction management device is to confirm and to carry out which available service among the SCP and to call these services with particular order for the subscriber.

Summary of the invention

The purpose of this invention is to provide through allowing the subscriber to have the method and apparatus of serving the shortcoming that overcomes current techniques more than a kind of IN for a calling.

In first aspect of the present invention; A kind of processing and the relevant intelligent network service method of calling to the subscriber of mobile telecom network proposed; This network comprises Control Node, attaching position register and one or more SCP, and this method may further comprise the steps:

A. said Control Node is sent one or more requests of the routing iinformation relevant with said calling to said attaching position register;

B. said Control Node receives the service trigger element relevant with said service from said attaching position register;

C. said Control Node uses said service trigger element in said one or more SCPs, to call said service;

D. said Control Node from said one or more SCPs receive with said triggering element the related said service information of being correlated with.

This subscriber that can serve for the one or more IN that subscribed a calling that belongs to the subscriber in this way, handles a plurality of service trigger elements.The IN service need not known the existence in one or more other IN services of the Control Node that is used for this calling.In other words, first service need not know whether will call second service, vice versa.Because service does not require that service may operate on the different platform and can be supplied by different sellers about possibly call the knowledge of other IN service for this calling.

There are some embodiment of the present invention.

For example; The present invention can stipulate that attaching position register sends the first service trigger element in said a plurality of service trigger element in response to first request of routing iinformation, and sends the second service trigger element in said a plurality of service trigger element in response to second request of routing iinformation.

First request of said routing iinformation can comprise:

-subscriber's Mobile Subscriber International ISDN Number.

First request responding to route information can comprise:

-the first service trigger element.

Second request of routing iinformation can comprise:

-subscriber's Mobile Subscriber International ISDN Number;

-HLR should suppress the indication of the first service trigger element in said response.This indication can be " suppress T-SCI " parameter for example.

Second request responding to route information can comprise:

-be used to call out the MSRN that is served the subscriber;

-the second service trigger element;

The prefix of-subscriber's MSRN or suffix.

Because the MAP segmentation, MAP message can be sent to GMSC from HLR in a plurality of SCCP message.First service, for example prepaid accounting service is carried out in first SCP, second service, for example PGS carries out in the 2nd SCP.

In this way, can prepaid services and PGS be offered same subscriber; Prepaid services and PGS can move on different platform and be uncorrelated each other.

When the present invention is used for PGS, calls out the subscriber and can listen to any call proceeding message, even when the early stage calling that utilizes optimum route is transferred or late period, the calling switching took place.

Another advantage of the present invention is can PGS be offered virtual private net (VPN) subscriber.

In second aspect of the present invention, a kind of processing and the Control Node that the subscriber's of mobile telecom network the relevant intelligent network of calling is served proposed, this network comprises said Control Node, HLR and one or more SCP; The Control Node configuration is used for sending to said HLR one or more requests of the routing iinformation relevant with said calling; Control Node also disposes and is used for receiving a plurality of service trigger elements that are associated with said service from said HLR, and is used for through using said triggering element to call said service at said one or more SCP; Control Node further configuration be used for from said one or more SCP receive with said triggering element the related service information of being correlated with.

In a preferred embodiment, Control Node comprises GMSC.In any case Control Node also can comprise the equipment such as MSC or SCP.

The third aspect of the invention has proposed a kind of computer program, and this computer program comprises causes computer to carry out the program command according to method of the present invention.

Computer program can be stored on the carrier, and can comprise the computer executable instructions that causes the computer execution to according to method of the present invention.

The carrier of computer program can be recording medium, computer storage, read-only memory or charge carrier signal.

The present invention proposes to provide for the particular call type to the subscriber multiple IN service.So far, HLR can register a plurality of indications (after this be called IN and trigger element) that specific IN type of call is subscribed.

Embodiment

For the purposes of the present invention, the MT call treatment among the GMSC can be divided into two logical gates:

(1) called processing;

(2) the roaming branch line is handled.

Called processing comprises from HLR obtains (retrieve) T-CSI and calls CAMEL service.The one CAMEL service can be forced call blocking or can be applied the calling switching.Usually, for the situation of being called out subscriber's roaming, CAMEL service also can be used for stopping chargeing.HLR also can return other IN with T-CSI and trigger element.

The roaming branch line is handled and to be comprised obtaining MSRN and will calling out to be routed to from GMSC from HLR and stop MSC, and MSC called party registers at this constantly in termination.Notice that " roaming branch line " is applicable to that on an equal basis the subscriber is being visited public land mobile network (VPLMN) and the situation of subscriber in Home Public Land Mobile Network network (HPLMN).That is to say, in this example " roaming " be not associated with " in another network or another country ".

The present invention proposes circuit, carry out calling of two IN services for MT calls out along above-mentioned difference.According to the present invention, can define two types the IN service that is used for the MT calling:

(1) IN of ability that the control that need call out MT and possibly needing influence the route of this calling serves.The IN service of these types also need be known destination subscriber's position, thereby can apply charging.

(2) IN that only requires destination subscriber's roaming branch line serves.This type IN service is only being set up the roaming branch line, when promptly GMSC has received MSRN from HLR, just is called.

If HLR returns switching number (FTN) rather than MSRN, will there be the roaming branch line so, and will can not calls the IN service relevant subsequently with roaming branch line.

Fig. 1 is the block diagram of the current techniques configuration of the equipment in the mobile telecom network.Shown entity is at least at the conceptive intelligent network that is different from mobile communications network that belongs to.Intelligent network comprises HLR 111, SCP1 121, SCP2 122 and GMSC 110.GMSC 110 and SCP1 and SCP2 and HLR111 dock, and trigger function to carry out well-known IN.SCP1 and SCP2 can be by the intelligent network services of sequence call during being included in the processing Mobile terminating call.

Fig. 2 is the signaling diagram according to method and apparatus of the present invention, and it has the general view of the relation between the various elements.This method may further comprise the steps:

One or more requests that step 101 Control Node 110 is sent the routing iinformation relevant with said calling to HLR 111;

Step 102HLR 111 sends a plurality of service trigger elements that are associated with said service to said Control Node 110;

Step 103 Control Node 110 uses said triggering element in one or more SCPs 121,122,123, to call one or more services;

The said one or more SCPs 121,122,123 of step 104 to said Control Node 110 send with said triggering element related one or more services information of being correlated with.

Fig. 3 is the block diagram according to equipment of the present invention and their correlation.

Line between said (equipment) is represented communication path.HLR 111 can communicate by letter with VMSC 112 with GMSC 110.GMSC can communicate by letter with other invoked subsequently SCP (SCPn) 122 with SCP1 121.GMSC 110 can communicate by letter with VMSC 112.

Fig. 4 is the signaling diagram of method embodiment of the present invention, and this embodiment comprises the communication sequence between the equipment shown in Figure 3, and said equipment comprises GMSC 110, HLR 111, a plurality of SCP121,122 and VMSC 112.In this example, the subscriber to have subscribed the CAMEL service and subscribed in addition possibly be at least one service of IN service.Example hereto only shows and the communicating by letter of two SCP 121,122.But, can be the 3rd SCP repeating step 6-11, and by that analogy.Following steps take place:

Step 401ISUP initial address message (IAM) arrives GMAC 110; GMSC 110 analyzes the called party number among the ISUP IAM and derives this called party number is the MSISDN that belongs to its network.

Step 402GMSC 110 sends MAP to HLR 111 and sends routing iinformation (SRI).GMSC110 indicates it to support CAMEL in MAP SRI.

Step 403 called party has the reservation to the CAMEL service that is used for the MT call treatment.The result is, HLR 111 sends MAP SRI-Res to GMSC 110, and it comprises and is used for the IN trigger message that MT calls out, T-CSI.

Step 404GMSC 110 uses T-CSI to call the CAMEL service.The inner GSM service of GMSC 110 illustrations function of exchange (gsmSSF) entity; GsmSSF sends CAP Initial Detection Point (IDP) to SCP.The address of SCP1 121 with obtain from T-CSI with other relevant data of this IN dialogue.GsmSSF function and GMSC interworking.Be based on define in user's the reservation and from the information that HLR sends to GMSC, the service trigger in GMSC and the gsmSSF is set.These triggerings are used to indicate gsmSSF when should communicate by letter with gsmSCF.Next this will confirm how to handle the service based on IN.

Step 4,05S,CP1 121 continues (CUE) response with CAP, so that notice GMSC 110MT call treatment can continue, promptly can call-delivery be given and called out the subscriber.Control session between SCP1 121 and the GMSC110 can keep.CAMEL service among the SCP1 121 need not have the knowledge of serving about other IN except the current executed of this CAMEL service.

Step 406GMSC110 sends second inquiry to HLR 111, promptly sends the 2nd MAP SRI to HLR 111.The 2nd MAP SRI comprises " suppressing T-CSI " sign.

It is the 2nd SRI that the existence of step 407HLR 111 through " suppress T-CSI " identifies this MAP SRI, and through send to the current VMSC that registers 112 of called party MAP Provide Roaming Number (PRN) respond.

Step 408VMSC was used in the MSRN of this calling in 112 minutes, and through sending MAP PRN-Res and return this MSRN to HLR 111 to HLR 111.

Step 409HLR 111 is through sending MAP SRI response (SRI-Res) and this MSRN is transmitted to GMSC 110 to GMSC 110.Called out the subscriber and subscribed the 2nd IN service that is used for the MT call treatment.The 2nd IN service is like the front open described roaming branch line of part treatment type of the present invention.HLR 111 comprises the IN trigger message that is associated with this 2nd IN service in said MAP SRI-Res.For the purposes of the present invention, this 2nd IN trigger message called after " RICK " (roaming branch line IN kind keyword).RICK can have the structure like T-CSI or TICK (stopping IN kind keyword).In order to receive RICK, (its this information element of support of indication in the step 6), promptly it supports RICK to GMSC 110 at the 2nd MAP SRI.The indication of " supporting RICK " is similar to the indication of " supporting TICK "." the supporting TICK " of sending to HLR from GMSC shows that to HLR it supports TICK.TICK has comparable functional with T-CSI; But TICK is not standardized.

Step 410GMSC 110 recognizes that MSRN is attended by RICK.RICK roams the indication that branch line should be obeyed the IN service for GMSC 110 as showing.Therefore, GMSC 110 uses RICK to call the IN service through sending CAP IDP to SCPn 122.The address of SCPn 122 with obtain from RICK with other relevant data of this IN dialogue.

Step 411SCPn 122 is with CAP CUE response, and notice GMSC 110 these MT call treatment can continue, and promptly can be established to the roaming branch line of being called out the subscriber.

Step 412GMSC 110 is established to the roaming branch line of called party subscriber through sending ISUP IAM to the destination switch.This ISUP IAM comprises the MSRN that receives from HLR 111.

Step 401-408 representes general GSM call treatment.

Step 409 expression is to the improvement of existing MT call treatment.HLR 111 generally will only return MSRN and give GMSC 110.Step 409 couple MAP SRI-Res has added RICK.

Step 410 does not exist in existing roaming branch line is handled with 411.These steps are illustrated among the GMSC110 and call what the 2nd IN that is used for the MT call treatment served.

When this calling was passed to by the calling subscriber, two IN services can be kept effectively.The IN service that triggers as sending the result of T-CSI to GMSC 110 can be kept effectively whole calling, and is had a complete available ability according to what the IN agreement that is used for that service allowed.

The 2nd IN service that triggers as sending the result of RICK to GMSC 110 also can be kept effectively whole calling.But this IN service should be used the IN ability with some restriction.As an example, this service should not used and called out switching, because that will influence the prepaid services of this calling.

The present invention can be applied in dissimilar GSM and call out in the switching.Through get be similar to personal greeting service (PGS) service as an example, can fully demonstrate this point.Under the situation of calling out switching, the destination of calling changes.When some Carrier Requirements take place when the calling switching to Voice Mailbox, the PGS end of service.

About under the situation of calling out switching, stopping the PGS service; The basic calling switching that has two types: call out switching (LCF) in early stage calling switching (ECF) and late period; Early stage when calling out switching when in GMSC 110, taking place, GMSC 110 receives from HLR 111 and is used for the MSRN of this calling and sets up the roaming branch line.GMSC 110 will not be established to called party's roaming branch line, and as a result of, will never call roaming branch line IN service.

Call out in early days in the situation of switching, HLR 111 does not return MSRN and does not return RICK according to the present invention in the 2nd SRI result.GMSC 110 is transferred to the switching destination with this calling now, and it can be for example Voice Mailbox or end of calling service.Because HLR 111 does not return RICK, will not exist PGS to call.Call out the subscriber and can listen to any announcement that Voice Mailbox is play now, even Voice Mailbox has been postponed the duration that limits with the generation of ISUP response message (ISUP ANM).

When in VMSC 112, taking place to transfer late period, (Optimal Routing of Late Call Forwarding is ORLCF) so that return to GMSC 110 with call treatment can to use the best route of calling out switching late period subsequently.GMSC 110 stops (terminate) this roaming branch line, and thereby roaming branch line IN service will be terminated equally.Call out late under the situation of switching, said calling has been routed to the destination MSC that is called out the subscriber.The situation of calling out switching when late period takes place, VMSC 112 can to GMSC 110 send MAP recover call treatment (Resume Call Handling, RCH); The transmission of MAP RCH is the part of ORLCF.

When GMSC 110 receives MAP RCH and approval to the request of ORLCF, its discharges roaming branch line and creates the switching branch line.MPTY can be listened to any announcement that is generated by the switching destination.

Some operators adopt Voice Mail System, and initial thus announcement is free.This can realize through the generation that makes Voice Mailbox postpone ISUP ANM.If PGS remains valid under these circumstances, MPTY will can uppick not accomplished any announcement of playing between message (ACM) and the ISUP ANM in the ISUP address so.Reason is that the personal greeting service is remained valid, up to detecting ISUP ANM.Will be not under the sort of situation can the uppick Voice Mailbox initial announcement.

The invention solves that problem, PGS will be terminated under the situation of switching associating ORLCF because call out late.

Do not stand ORLCF if call out switching late period, roam the branch line service so and can keep watch on isup message such as call proceeding (CPG) and ACM.These isup messages can indicate switching to take place.

The service node solution of some Using P GS of operator.This means the subscriber for PGS, the roaming branch line need be through special service node (be positioned at and be embedded in the ISUP communication link that is used to roam branch line) route.Service node will be given destination MSC this broadcast calls.Can realize route according to the present invention through the roaming branch line of service node.The IN service that utilizes RICK to call can cause calling out quilt through said service node route for MSRN provides prefix.

Replacedly, the RICK that is included among the SRI-Res can have the form of number prefix; Before this calling is transferred to next switching node, this RICK is placed on the front of MSRN such as the switching node of GMSC.

Can be configured in the B-number analysis in this switching node, make RICK cause choosing the route of said service node.

The notion of IN service reservation or general of roaming branch line can be used for the service of following type:

-personal greeting: have only when the roaming branch line is successfully set up and need play personal greeting; If owing to reason whatsoever, the roaming branch line does not have to set up or before replying, stops, and does not need personal greeting so.Operator can hope calling PGS before for call distribution MSRN.Such effect possibly be that when the switching to second called party takes place, MPTY will still be heard the personal greeting of first party.In addition, such configuration will have the effect that possibility does not have uppick calling switching announcement.

-service node route: for certain subscriber, the roaming branch line possibly be routed through service node.

-carrier is selected (Carrier selection): the subscriber can subscribe the carrier that only is applicable to the roaming branch line and select service.

When HLR 111 sends when comprising the SRI-Res of MSRN to GMSC 110, it can comprise RICK.As optional execution mode; HLR 111 can be applied in the standard (HLR 111 may apply criteria for the inclusion of RICK inSRI-res) that comprises RICK among the SRI-Res, and being similar to whereby, HLR 111 is applied in the situation that comprises the standard of T-CSI among the SRI-Res.These standards for example can be:

-have only when the subscriber is in HPLMN, in SRI-Res, to comprise RICK;

-have only when incoming call is audio call, in SRI-Res, to comprise RICK.

Not every MT calling needs to stop the IN service.Similarly, not every MT calling needs the RICK service.As an example, when pre-paid subscribers was in HPLMN, HLR111 can suppress T-CSI in SRI.The result is not have the MT call service to be triggered.If still need call the service of roaming branch line in this case, HLR 111 can comprise RICK in a SRI-Res so.Among the GMSC 110 to the further processing of RICK as previously mentioned.

Fig. 5 is the signaling diagram of method embodiment of the present invention, wherein through carrying out calling a plurality of services by GMSC 110 to HLR 111 inquiry a plurality of (IN) services before setting up the roaming branch line at GMSC 110.In this embodiment, HLR 111 sends all information of said IN service in first inquiry.Step 501-502 carries out according to current techniques.The present invention relates to 3 SCP here in the example, although can be applied to a plurality of SCP.

Step 501ISUP IAM arrives GMSC 110.

Step 502GMSC 110 analyzes the called party number among the ISUP IAM and derives this called party number is the MSISDN that belongs to its network.GMSC 110 sends MAP SRI to HLR 111.GMSC 110 indicates it to support CAMEL in MAP SRI.GMSC can support a plurality of CAMEL stages.

Step 503 called party has the reservation to the CAMEL service that is used for the MT call treatment.The result is, HLR 111 sends MAP SRI-Res to GMSC 110, and it comprises and is used for the IN trigger message that MT calls out, T-CSI.

Step 504GMSC 110 uses T-CSI to call the CAMEL service.The inner gsmSSF entity of GMSC 110 illustrations; GsmSSF sends CAP IDP to SCP 121.The address of SCP1121 with obtain from T-CSI with other relevant data of this IN dialogue.

Step 5,05S,CP1 121 continues (CUE) with CAP or CAP connects (CON) response, so that notice GMSC 110MT call treatment can continue, promptly can call-delivery be given and called out the subscriber.Depend on the requirement of IN service, the control session between SCP1 121 and the GMSC 110 can keep or stop.CAMEL service among the SCP1 121 does not have the knowledge of serving about other IN except the current executed of this CAMEL service.

Through calling the 2nd IN service response, the 2nd IN service can be still the CAMEL service to step 506GSMC 110 based on T-CSI.The address of SCPn 122 obtains from the 2nd T-CSI.

Step 507SCP, promptly can give call-delivery and called out the subscriber so that notice GMSC 110 these call treatment can continue with CAP CUE or CAP CON response.Here, same, the CAMEL service among the SCP2 122 does not have about first service of this calling and the knowledge of the 3rd service.

Whether step 508GMSC 110 inspections serve for this subscriber provides other IN; If what provide has, it responds through calling the 3rd IN service based on T-CSI so, and the 3rd IN service can also be the CAMEL service.The address of SCP3 123 obtains from the 3rd T-CSI.
