Abstract

This invention provides a method for avoiding repeated trigger of intelligent services including the following steps: a service switch point (SSP) captures a user call and judges if it has opened the intelligent service for the user number carried in the call, if so, it reports it to SCP, if not, it quits from the flow, b, SCP receives the number to carry out related intelligent service logic process and adds attached identification before the number to be sent to SSP, c, SSP receives the number with attached identification and removes the attached identification and continues the work.

Description

A kind of method of avoiding repeated trigger of intelligent services

Technical field

The present invention relates to the intelligent network field, be meant a kind of method of avoiding repeated trigger of intelligent services especially.

Background technology

In intelligent network, Service Switching Point also is used for receiving and the identification intelligent service call except finishing the basic access function, and communicates by letter with Service Control Point, goes to influence the call flows of SSP, realization IN service by the service logic among the SCP.

Along with the development of intelligent network technology, at present, not only can carry out IN service towards the calling subscriber, also can carry out IN service towards the called subscriber.

For IN service towards the calling subscriber, usually initiatively import access code mode trigger intelligent business by the calling subscriber, as IP phone 17951, intelligent card numbers phone 201 or the like is realized by the calling user dials access code.

For IN service towards the called subscriber, can use for reference the principle of calling user dials access code trigger intelligent service, when the calling subscriber calls out the called subscriber, mode by the called number of calling subscriber's input tape access code, be " access code+called number " mode, trigger called IN service by access code.But, adopt this mode, when dialing called number, the user must have access code, broken the use habit that the calling subscriber directly dials the called subscriber.The more important thing is that owing to be to provide IN service to the called subscriber, for the calling subscriber, the called number result who dials true number of called subscriber and band access code is the same, so be difficult to allow the calling user dials access code.Therefore, this mode makes towards called subscriber's IN service to be difficult to carry out and promote.

Therefore, for IN service, generally adopt real called number to come trigger intelligent business towards the called subscriber.After SSP intercepts and captures the real called party number, judge the IN service of being applied for according to called number, insert the corresponding service access code then and report SCP before this called number, SCP after handling IN service deletes service access code, and real called number is issued to SSP, carry out follow-up connection.But, because SSP is according to real called party number trigger intelligent business, and the called number that SCP issues also is the real called party number, therefore after SSP receives this called number, may judge this called number once more and trigger intelligent business once more, cause the repeated trigger of IN service.

Summary of the invention

In view of this, main purpose of the present invention is to provide a kind of method of avoiding repeated trigger of intelligent services, to solve the repeated trigger of intelligent services problem.

Realize the present invention, need following steps:

Customer call is intercepted and captured in a, service switching point, judges whether to have opened IN service for the Subscriber Number that carries in this calling, if then, with Subscriber Number reporting service control point SCP, otherwise withdraw from this flow process;

B, SCP receive Subscriber Number, carry out corresponding intelligent service logic and handle, and add that before Subscriber Number additional identification is issued to SSP;

The Subscriber Number of c, SSP receiving belt additional identification, the deletion additional identification is carried out follow-up continuing.

Wherein, the described Subscriber Number of this method is: rear subscriber number or called number.

Wherein, the described SSP of step a is according to the Subscriber Number trigger intelligent business, and report the step of SCP further to comprise Subscriber Number: the Subscriber Number that SSP will have the service access code of IN service reports SCP.

Wherein, the described additional identification of step b is the annex prefix, and additional prefix is the fixed value inequality with the user number harbour, the difference additional prefix of perhaps additional prefix for being provided with according to the follow-up selected different route that continues of SSP.

By said method as can be seen, the method of avoiding repeated trigger of intelligent services provided by the invention, in the flow process that continues, SCP can be handed down to the Subscriber Number of the additional prefix of SSP band, Subscriber Number effective and that SSP had before received is distinguished, and has solved professional repeated trigger problem.In addition, for the user, do not need the user to import the triggering that access code just can be realized IN service by hand, it is more convenient that the user is used, and helps carrying out of IN service.

Embodiment

The invention discloses a kind of method that prefix is avoided repeated trigger of intelligent services of adding that adopts, promptly intercept and capture called number by SSP, insert the corresponding business access code at the IN service of judging its application on the SSP and before this called number, calling is reported to SCP, and goes up the handling process that the service logic that loads goes to influence calling by SCP; Then, SCP increases additional prefix before being handed down to the called number of SSP; After SSP receives the called number of the additional prefix of band, the additional prefix before the SSP deletion called number, and called number is routed to tandem exchange (MS) or end office (EO) (LS) etc. carries out follow-up continuing.As can be seen, owing to adopted additional prefix that twice called number that SSP receives distinguished, avoided the repeated trigger of IN service.

Fig. 1 is the flow chart of called number trigger intelligent business of the present invention.If user 0251234888 has applied for dialing the IN service that this Subscriber Number triggers this user towards called IN service by other users.Below to call out this user with the fixed telephone subscriber be embodiment, with reference to Fig. 1, the present invention is described in more detail.

Step 101: landline telephone calling subscriber 0254565888 calls out called subscriber 0251234888, end office (EO) (LS) will have the initial address message (IAI of additional information through tandem exchange (MS), InitialAddress Message With Additional Information) issues SSP, wherein, contain called number 0251234888 in this IAI message.

Step 102:SSP receives IAI message, extracts called number from IAI, and called number is judged, if this called number is not opened IN service as yet, then withdraws from this flow process, otherwise according to the called number trigger intelligent business.In this example, SSP extracts called number from IAI after, judge called number 0251234888 for having opened the user of certain IN service, then before called number, insert the access code 238 of this IN service, and to SCP transmission startup DP message (IDP, Initial DP), request SCP is current call setup IN service control relation, carries out the processing of IN service.Wherein comprise the called number 2380251234888 of being with service access code among this IDP.

Step 103-104:SCP receives IDP, carries out corresponding IN service flow process according to service access code, carries out corresponding intelligent network service logical and handles.

SCP is this call setup control relation, issues request report BCSM event message (RRBE, Request Report BCSM Event) to SSP, goes for and asks SSP dynamic-configuration Detection Point (DP, Detection Point).

SCP carries out the deletion of service access code with 2380251234888 among the IDP then, translates real called number 0251234888, and is ready to metering data, sends charging request message (AC, Apply Charging) to SSP.

Step 105:SCP increases accessory identification before called number, for example additional prefix 902, the called number 9020251234888 that will add additional prefix by connection request message (Connect) is issued to SSP as destination Mobile Station International ISDN Number, and indication SSP is connected to destination Mobile Station International ISDN Number 9020251234888 with calling.

Step 106:SSP receives Connect message, extract the called number 9020251234888 that adds additional prefix, and the additional prefix No. of deleting 902 are handled obtain the real called party number, and called number 0251234888 issued be connected to LS or MS, set up follow-up connection.

Wherein, above-mentioned additional prefix can use unification setting in various IN services, a fixed value promptly is set as additional prefix, and it is not identical with common called number head wherein should to add prefix.For example additional prefix can unify to be set to 902, as long as it is the action that 902 number is promptly done this 902 field of deletion that SSP receives prefix, implement comparatively easy, unify to be provided with owing to be to carry out unified planning, can avoid additional prefix identical, prevent the false triggering of IN service with real user number prefix.

Also can be set to different values in addition according to different callers, the called prefix that adds.For example, when IN service when local SSP triggers under by the called subscriber, local caller is initiated can use additional prefix 901 to the called calling in this locality, and the strange land caller is initiated can use additional prefix 902 to the called calling in this locality.When in the follow-up flow process that continues, selecting route like this, can carry out the selection of route according to the different value of additional prefix.

The above is to be that example describes with the called number trigger intelligent business, and this method also can be used for the flow process with the calling number trigger intelligent business, and its flow process is identical with last example, just be calling number at object.

The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
