Description

Caller finishes the implementation method of conversation in a kind of intelligent network call conversation

Technical field

The present invention relates to the intelligent network business technology, relate in particular to account card class intelligent network business technology.

Background technology

Intelligent network is on the infrastructure network that has exchange and transmission now, for telecommunication service a kind of complementary network structure that (or claiming value-added service) is provided with is provided fast, conveniently, economically.It is to accomplish quick, economy and convenient that intelligent network provides the outstanding advantage of new business.Intelligent network is a core with computer and database, and in theory, the new business that intelligent network can provide is unlimited.

The chief component of intelligent network has: Service Switching Point is used for discerning the calling of user to intelligent network; Service Control Point is finished the control to business; Service management node (SMP) is finished operation, maintenance, management and supervision in the intelligent network.

In the intelligent network of reality uses, especially in the intelligent network business of account card class, when calling subscriber A calls out the party B-subscriber, after the B off-hook, A and B conversation are in communication process, if calling subscriber A thinks initiatively to finish conversation, continue to call out C user, but B does not want to finish the conversation with A.Present method is after the A on-hook, to re-enter the IN service access code, and called number C is imported in the password authentification of input card number later on.It is very inconvenient to operate.

Summary of the invention

The present invention proposes the implementation method of caller end conversation in a kind of intelligent network call conversation, support that the calling subscriber does not need on-hook just can finish current talking, and can directly import another number and carry out other callings.

Key of the present invention is that the operation exchange point apparatus monitors BCSM (Basic Call State Model BCSM) incident of button in can supporting to converse, and is called the omidcall incident among the present invention; SCP wants initiatively to initiate the request of this incident of registration to SSP, and can accept the omidcall event report from SSP, and is correspondingly processed.

To achieve these goals, the present invention by the following technical solutions: caller finishes the implementation method of conversation in a kind of intelligent network call conversation, comprises the steps:

Step 1 loads omidcall action listener and reporting modules on Service Switching Point; On Service Control Point, load the business logic modules of supporting caller end conversation in the conversation; Business logic modules receives after the called off-hook event, carries out called off-hook flow process, and service control point sends the request of registration omidcall incident to professional transfer point in this flow process; After SSP received the request of described registration omidcall incident, application DTMF resource was with the button of monitoring caller;

Step 2 before described caller end of conversation, if SSP listens to the key that appointment in the registration omidcall incident is pressed in described caller, then discharges calledly, and reports corresponding omidcall incident to SCP; SCP receives after this event report, points out the calling subscriber to do further operation according to the indication of business logic modules.

Further, said method, in step 2, call flow for the calling subscriber, with regard to application, the calling subscriber has absolute control to this conversation, and whether the calling subscriber can select to finish at once to carry out other calling later at once with called conversation, and does not need initiatively to carry out system's authentication once more after the on-hook.

Further, said method, in step 1, business logic modules abides by ITU-T CS1 intelligent network standard and the professional customization application standard of enhancing is write.

Further, said method, in step 1, Service Switching Point is to use that Intelligent Network Application Protocol triggers this intelligent network business in the signalling system No.7; Service control point is by being provided with the type that the BCSM event argument need to determine registered events in request report BCSM event action, Service Switching Point is distinguished different incidents according to the different parameters in the solicit operation.

Compare with prior art, adopt the inventive method, can make the calling subscriber under permanent situation, finish this calling, finish to initiate calling again according to the business logic modules on the service control point apparatus after this conversation to other numbers, brought convenience to the calling subscriber, made the calling subscriber in conversation, occupy initiative.

Embodiment

Be described in detail below in conjunction with the enforcement of accompanying drawing to technical scheme, following examples of the present invention are based on a kind of system of fixed network intelligent network, below describe combining with the fixed network intelligent network:

Among the present invention, the notion of core is exactly the BCSM incident of omidcall, and this event class is to initiate later on by the control of the business logic modules on the service control point and at called off-hook like other BCSM incident, finally registers on Service Switching Point.Service Switching Point is monitored the button input of caller in the communication process, in case be the button of (parameter is determined in the registration BCSM request) of satisfying condition, Service Switching Point will discharge called connection, and to service control point transmission event report, business logic modules on the service control point receives this incident and makes corresponding reaction later on, make the calling subscriber can under permanent situation, finish and called conversation, continue other operation.

Use system of the present invention and use intelligent equipment, as shown in Figure 1, comprise: the service control point (SCP), the service switching point, service management point SMP, SMAP SMAP, Service Database point SDP, the device that service creation environment SCE, the present invention relate generally to is: operation exchange point apparatus and service control point apparatus.In the embodiment of the invention, SSP has the function of registration omidcall incident, registration omidcall incident only need be operated SSP by SCP control, and SSP can use Intelligent Network Application Protocol triggering intelligent network service in the signalling system No.7, and and SCP carry out alternately, when registration BCSM incident, originally can register called off-hook event, in case called off-hook event takes place, in the handling process of the called off-hook event of service logic, SCP continues to initiate the operation of registration omidcall incident, and relevant parameter is passed to SSP, finishes registration by SSP.

Except SSP need support the monitoring of omidcall incident, the business logic modules of omidcall event registration is initiated in the responsible control that also will load the present invention's description on SCP to SSP, when the service-user calling is called, in case called off-hook, business logic modules will be according to setting to SSP initiated event register requirement.

Below in conjunction with Fig. 2 and Fig. 3, signaling process and the call flow of using the inventive method are done explanation:

Fig. 2 is a signaling process schematic diagram of the present invention; Fig. 3 is a call flow schematic diagram of the present invention, and the processing method that the present invention calls out a service-user has been described:

Step 301, the intelligent network business that triggers the support omidcall incident on the SCP is called out in user's dialing, and corresponding INAP signaling is exactly the IDP (starting DP) among Fig. 2;

Step 302, system carries out authentication to service-user, and corresponding INAP signaling is exactly the CTR (being connected to resource) among Fig. 2, a series of P﹠amp; C (prompting is also collected user profile) and RR-P﹠amp; C (prompting is also collected the user profile response) and DFC (cut-out connection resource);

Step 303, business logic modules is after service-user has been imported called number B, send BCSM incidents (not comprising the omidcall incident) such as the called off-hook of registration to SSP, send the B message that continues to SSP after succeeding in registration, corresponding INAP signaling is exactly RRBE (request report BCSM incident, no omidcall) and the CONNECT (it is called to continue) among Fig. 2;

Step 304, after the called B ring, if called off-hook, corresponding INAP signaling is exactly the ERB (BCSM event report, called off-hook) among Fig. 2; If called do not have an off-hook, then SSP returns called no response incident and gives SCP, and SCP walks no response incident flow process;

Step 305, business logic modules receives after the called off-hook event, walk called off-hook flow process, in this flow process, send the request of registration omidcall incident to SSP, the while call establishment, calling and called conversation, corresponding INAP signaling are exactly the RREB (request report BCSM incident, omidcall incident) among Fig. 2;

Step 306, SSP receives after the request of omidcall register of event, can go to apply for the DTMF resource, is used for monitoring the button of caller;

Step 307, if end of conversation is preceding caller button (key of appointment in the BCSM incident of registration omidcall), SSP listens to after this incident, discharge called, report events corresponding such as omidcall to SCP, corresponding INAP signaling is exactly the ERB (BCSM event report, omidcall incident) among Fig. 2; If caller does not have button, then business logic modules is walked other flow processs before the end of conversation;

Step 308, SCP receives after the incident such as omidcall, walks corresponding event handling flow process according to business logic modules, the operation below service-user can continue according to the function that business logic modules provided.

Above-mentioned call flow has only illustrated that business logic modules registered the call flows of omidcall incident to SSP, for the call flows of not registering the omidcall incident, its difference is just in communication process, the latter does not support the response of caller key-press event, even the caller button is conversed and is still continued to keep, until The Calling Party Hooks On or Called Onhook or SSP end conversation, other handling process is all similar with the former, does not repeat them here.

From top embodiment as can be seen, finish the method for conversation by caller in the conversation of the present invention, can make the calling subscriber under permanent situation, finish this calling, finish after this conversation and can initiate calling again according to the service logic on service control point apparatus design to other numbers, with respect to the system that does not support the omidcall incident, brought convenience to the calling subscriber, made the calling subscriber in conversation, occupy initiative.

In GSM network and the same existence of the PHS network procotol similar to above-mentioned PSTN, the transmission of monitoring information such as caller button, listening mode in whether supporting to converse is provided in the agreement, the method that the present invention proposes is suitable equally in these networks.

Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
