Description

The method of remote service logical calling access SCP control logic, system and equipment

Technical field

The present invention relates to the intelligent network technology field, relate in particular to method, system and the equipment of intelligent network remote service logical calling access SCP control logic.

Background technology

In communication network, intelligent network is a complementary network structure of being responsible for professional control on switching network, and this network can make operator that all kinds of new business fast and effeciently are provided more economically.Along with enriching of business, the corresponding business combination is also more and more flexible, and operation system on-premise networkization and business logic modules change into the basic demand into Intelligence Network Development.

Typical networked deployment way is to be deployed on the different SCP (Service Switch Point, service control point) calling out access and miscellaneous service functional module such as service dispatching, charging etc.Certainly, each functional module also can be closed arbitrarily and be established, and same functional module also can be distributed on a plurality of SCP.Can carry out calling service mutually between each functional module.

For ease of describing, various functional modules all are called SCP, as will call out access module, service dispatching module, accounting module be called insert SCP, bus traffic is dispatched SCP, charging SCP, the miscellaneous service processing module all can be described as professional SCP.These are appellation in logic, and corresponding physical equipment with it must not arranged.

After the operation system networking was disposed, the realization of single traffic performance may need a plurality of SCP cooperations to finish jointly.Wherein, access SCP is responsible for the control relation with SSP (Service Switch Point, Service Switching Point), finishes by inserting SCP as control logics such as playback, playback collect the digits.SCP and SSP are conversational modes in the control procedure, if operation system is carried out business control by SSP, must in same session, realize, a corresponding SLPI (the Service Logic ProcessingInstance that inserts on the SCP of this session, all need later to call the respective control function that inserts SCP when Service Logic Processing Instance), other SCP needs to carry out control logics such as playback, playback collect the digits in the business logic processing process.

The multi-service combination then can relate to more SCP, forms a multi-level call relation.As shown in Figure 1, SSP is triggered to business and inserts SCP, inserting the SLPI that produces this professional triggering correspondence on the SCP, insert SCP according to the service logic needs, call SCP1, on SCP1, produce the pairing SLPI1 of calling service, so analogize, on the SCP that is called, all produce corresponding SLPI, in this multi-level call relation, can obtain to insert under the situation of SCP address, though can being interconnected to access SCP, other SCP carries out far call, but because this calling service can't find this professional triggering at the SLPI (Service Logic Processing Instance, Service Logic Processing Instance) that inserts on the SCP, thereby can't directly call the playback that inserts on the SCP, control logics such as playback collects the digits.

Under multi-level far call situation, the method for the professional SCP far call access SCP control logic that exists at present as shown in Figure 2.

Step 201:SSP is triggered to business and inserts SCP;

Step 202～step 203: insert SCP and call SCP1, SCP1 calls SCP2 according to service needed;

SCP1 can be a bus module, it also can be the miscellaneous service module, under the situation of bus traffic scheduling or a plurality of professional stacks, SCP1 need call SCP2 again, SCP2 is generally business module, as accounting module or VPMN (Virtual Private Mobile Network, VPMN) business module etc.Under business stack complicated situation, SCP2 may also need further to call other SCP, forms more multi-layered time call relation, describes with two-layer call relation here.

When the service logic on step 204～step 205:SCP2 need be carried out control logics such as playback, playback collect the digits, SCP2 finished inherent logic, and calling service returns indication SCP1, and SCP1 also finishes inherent logic and returns indication and give and insert SCP;

Step 206～step 207: insert SCP according to the calling service of SCP1 return carry out control operations such as playback, playback collect the digits after, call SCP1 and will control the result simultaneously and pass to SCP1, SCP1 calls SCP2, makes SCP2 continue the follow-up service logic of execution;

After step 208～step 209:SCP2 service logic finished, calling service returned indication and gives SCP1, and SCP1 returns indication to inserting SCP.

Such scheme as can be seen, under this invocation pattern, the service logic of invoked professional SCP can be interrupted by control logics such as playback, playback collect the digits operation and be a plurality of service logic submodules, and, in order to discern each submodule, different submodule calling interfaces also must be different.Simultaneously, calling professional SCP also needs correspondingly to cooperate, and removes to call a plurality of submodules of same business module in order, and handles playback, playback that each submodule of invoked professional SCP the returns indication of control logic such as collect the digits.Therefore, this mode is for all very inconvenience of the realization of calling professional SCP and invoked professional SCP.

For the more situation of business stack level, call relation is also complicated more, the service logic of invoked professional SCP can be interrupted by control logics such as playback, playback collect the digits equally and be a plurality of service logic submodules, call professional SCP for handling the indication of calling control logic of invoked professional SCP, also need self service logic interrupted and be a plurality of submodules, for all very inconvenience of the realization of calling professional SCP and invoked professional SCP.

In addition, the coupling that this method of calling also can make calling module be called between the module increases greatly, has damaged the modularization of service logic.

Also can trigger service request by other functional entity, for example various AIP such as sms center, Short Message Service Gateway (Advanced Intelligent Peripheral equipment, high-grade intelligent peripheral hardware) realize, give an example no longer one by one.

Call relation at more multi-layered time, also be by insert SCP in advance for the pairing SLPI of service trigger request distribute one can this SLPI of unique identification example ID, and by call operation with this example ID and insert SCP address and successively be delivered to invoked SCP, when invoked professional SCP need use the control logic that inserts SCP, find access SCP directly to call the corresponding control logic that inserts SCP according to inserting SCP address, insert SCP and find corresponding SLPI, and in this SIPI, carry out corresponding control logic according to example ID.Do not do more elaborations at this.

Can do further to optimize to the foregoing description, for service security provides safeguard.To handle CAP (customization that CAMEL Application Part, mobile network strengthen logic use in applying portion) speech business is that example is elaborated.

With reference to Fig. 4, in the present embodiment, comprise 3 SCP: insert SCP, SCP1, SCP2, wherein:

Insert SCP and be responsible for inserting CAMEL Application Part, the calling interface of control logics such as playback prompting is provided;

SCP1 is responsible for service dispatching, provides IDP (Initial Detection Point starts Detection Point) request to wait calling interface, is responsible for the scheduling to other professional SCP;

SCP2 realizes the real time billing logic, and the calling interfaces such as initial charging reservation at speech business are provided.

Signaling process figure below in conjunction with Fig. 4 is elaborated.

Step 401: the user makes a call, and SSP triggers service request to operation system, sends IDP message to inserting SCP, and access SCP generates corresponding SLPI according to triggering service request, and for this SLPI distributes an example ID, and be authentication code of this SLPI distribution;

Sending IDP message is first operation that SSP reports SCP in the intelligent call, has comprised the needed more comprehensive information of service logic.IDP message is that SSP grasps it and the information of SCP service logic needs is told SCP, so that service logic is obtained as required.

The example ID that above-mentioned access SCP distributes for this service trigger request can this business of unique identification trigger at the SLPI that inserts on the SCP, and authentication code then is used for authentication is carried out in the request of calling control logic, identifies illegally and calls, and refuse its call request.

Step 402: insert SCP finds its ownership according to user's phone number SCP1, call the IDP request call interface of SCP1, example ID, the authentication code that will insert SCP address, the corresponding SLPI of this service trigger request by the calling service operation pass to SCP1;

Example ID, the authentication code that inserts SCP address, the corresponding SLPI of this service trigger request passed to SCP1 to be realized by carry example ID and 3 parameters of authentication code of inserting SCP address, this professional corresponding SLPI of triggering in this calling service operation.

Step 403:SCP1 calls call charge service according to the decision of service dispatching strategy, and finds the SCP2 of service-user ownership, calls the initial charging spare interface of SCP2, will insert SCP address, example ID and authentication code by this call operation and be delivered to SCP2;

Step 404:SCP2 is when carrying out the call charge service logic, judge and to play current remaining sum to the user, be interconnected to access SCP according to known access SCP address, directly far call inserts the playback prompting interface of SCP, and carries example ID and authentication code in call operation;

Step 405: insert SCP and find corresponding service logical process example, and the identifying code that imports into is verified,, then refuse the calling service of SCP2 if checking is not passed through according to the example ID of carrying in the step 404; If the verification passes, insert SCP and send a plurality of DP points of RRBE message arrangement, the incident that notice SSP will receive, and execution in step 406 to SSP;

By disposing a plurality of DP points, SSP just can know that access SCP wants the incident that receives, and when these incidents took place, the SSP notice inserted SCP.

Step 406: insert SCP and send CTR (Connect To Resource connects the playback resource) message to SSP, request SSP is connected with the playback resource, prepares playback;

The playback of switch or playback number receiving resource are relatively independent, want to ask switch to give user's playback or collect the digits if insert the service logic of SCP, then must send this message to MSC/SSP.

Step 407:SSP issues PA (Play Announcement plays notice) message and gives MSC/SSP or AIP, asks the playback into the user.

Step 408: after executing PA, SSP sends SRR (Specialized ResourceReport, specific resource report) report of information reporting to inserting SCP, tells that inserting the SCP playback finishes.

Above step 405～step 408: insert SCP and find this to call out corresponding SLPI, and the legitimacy of authentication verification sign indicating number, be invoked at this and call out and carry out the playback control logic among the pairing SLPI to legal according to the example ID of being transmitted;

Step 409: after playback finishes, insert SCP and return the playback result to SCP2;

After step 410:SCP2 continued the logical process of follow-up initial charging reservation, return results was given and is inserted SCP1;

Step 411:SCP1 judges whether also to need to call other professional SCP, and processing finishes the back to inserting the SCP return results;

Step 412: access SCP judges and does not need when the user provides playback to collect the digits, and issues DFC (Disconnect Forward Connecting disconnects the connection of front) message and gives SSP, and request cut-out playback resource is connected with the user's;

Step 413: insert SCP and send RRBE (Request Report BCSM Event, the event request report of Basic Call State Model BCSM) a plurality of DP points of message arrangement to SSP;

Step 414: insert SCP and issue AC (Apply Charging implements charging) message to SSP, request SSP prepares to charge;

If the charging point of intelligent network is at SCP, SCP is handed down to SSP by the AC operation with relevant charge information according to calling subscriber's ownership place with after calculating with visiting, just comes into effect charging information collecting when in a single day SSP detects called subscriber answer.

Step 415: when main and/or called number change, insert SCP transmission CONNECT message informing SSP and change accordingly;

Above step 12～step 15 inserts IDP interface that SCP returns according to SCP1 to the SSP issuing message, issues the segmentation duration in AC message, and indication continues.

As seen, step 4～step 9 has realized that SCP2 directly calls the playback control logic that inserts SCP.

Among the above embodiment, so-called access SCP is the appellation on the function, for example, triggers service request if SSP directly sends to SCP1, and that then SCP1 played the part of is exactly the role who inserts SCP, should carry out the corresponding control logic that inserts SCP.
