Description

A kind of method that issues the intelligent public phone cost of the phone call

Technical field

The present invention relates to the Intelligent Pay Phone Service technology, particularly a kind of method that issues the intelligent public phone cost of the phone call.

Background technology

Intelligent network is a notion that is proposed by standardization body of International Telecommunications Union (CCITT) in 1992, be an energy fast, convenient, flexibly, economical, generate and realize the network system of various new business effectively.According to China's intelligent network system regulation, the intelligent network of China adopts the network system based on the service switching point.In net, disposed service switching point, service control point (SCP), service data point SDP, business management system SMS, service creation environment SCE, service management access device SMAF and ip intelligent peripherals IP, and formed national intelligent network by the NO.7 signaling network.

Intelligent Pay Phone Service is the public telephone service that relies on processes such as intelligent network platform complete connection, charging, control.It has gathered charging, route advantage and the IC-card characteristics easy to use of card number service, and public telephone service is finished in the cooperation of the IC-card public telephone terminal by correspondingly.Its sharpest edges are that the authentication to card is at intelligent network platform, and the anti-free call on sb. else's expense through illegal means ability of public telephone has effectively been improved at but not IC telephone terminal place.At present in the public telephone service of China, attended public telephone accounts for the overwhelming majority, comprise insert coins, ratio that unguarded public telephones such as magnetic card, IC-card public telephone account for is less.Traditional relatively non intelligent general phone service, Intelligent Pay Phone Service can be eliminated problems such as charging is inaccurate, free call on sb. else's expense through illegal means, illegal great number charge effectively, and can realize the specialized management of public telephone.

It is relevant with the control mode of calling to issue cost of the phone call in the Intelligent Pay Phone Service, and according to the switching equipment regulation and stipulation, calling out control mode has caller control mode, called control mode and three kinds of control modes not mutually.

Wherein, called control mode, the release of calling out is controlled by the callee, its control procedure is as follows: behind the end of conversation, if The Calling Party Hooks On, and all relayings, comprise the subscribers feeder of originating switch (LS) to called phone, all can not discharge, caller is once more after the off-hook, still can with called continuation conversation; Have only Called Onhook, in the middle of all of speech channel process office points just can carry out the back to speech channel discharge.

As shown in Figure 1, Fig. 1 is the signaling process figure of called control mode.Behind the end of conversation, if The Calling Party Hooks On, caller LS is to the SSP signal CCL that sends that The Calling Party Hooks On, and SSP receives signal CCL, temporarily hangs the speech channel between main dialing telephone and the SSP; Caller is off-hook once more, and caller LS is to the restoring signal RES and the reanswer signals RAN of SSP transmission forward direction, and SSP receives signal RES and RAN, reactivates the speech channel between main dialing telephone and the SSP.If Called Onhook, called LS sends release signal REL to SSP, and the back is to discharging whole speech channel.

In intelligent network system, SSP is between caller LS and called LS, therefore, adopt the mode of called control, The Calling Party Hooks On and the action of off-hook can be satisfied two requirements simultaneously: action that The Calling Party Hooks On, really do not hang up speech channel, but temporarily hang speech channel, keep speech channel and use for issuing telephone expenses; The action of caller off-hook reactivates speech channel, and SCP issues cost of the phone call to main dialing telephone.

What is called is control mode not mutually, and caller and called both sides are the not release of controlling call, and either party's on-hook is called out promptly and discharged.At present, at some local networks, Integrated Service Digital Network and mobile network, employing all be control mode not mutually.

Issue the cost of the phone call of intelligent public phone in the prior art, the calling control mode of employing is a control mode not mutually.As shown in Figure 2, Fig. 2 is for issuing the method flow diagram of intelligent public phone cost of the phone call in the prior art, and this method may further comprise the steps:

Step 201～202: behind the end of conversation, when The Calling Party Hooks On, caller LS sent user's on-hook signal CCL to SSP;

Step 203:SSP receives user's on-hook signal CCL that caller LS sends, and discharges whole speech channel;

Step 204～205: the caller automatic off-hook, the access code of group intelligent network system triggers Intelligent Pay Phone Service;

Step 206: Intelligent Pay Phone Service is triggered, and is communicated with the speech channel between main dialing telephone and the SCP;

Step 207～208:SSP reports ticket information to SCP, and SCP issues cost of the phone call and gives main dialing telephone to the main dialing telephone transmit telephone bill;

Step 209: main dialing telephone reports the ticket confirmation to SSP;

Step 210:SSP sends release signal REL signaling to main dialing telephone, and the back disconnects caller to the speech channel that discharges between SSP and the main dialing telephone.

In the above-mentioned calling control mode of not controlling mutually, after the end of conversation user on-hook, speech channel is released immediately, and in order to issue cost of the phone call, main dialing telephone need be initiated call once more and be operated and reconnect speech channel.Communication process and issue the telephone expenses process and carry out in twice conversation respectively, speech channel discharge and to set up reconnecting of speech channel more consuming time.In general, speech channel discharges needs 2 seconds, and setting up reconnecting of speech channel needs 2 seconds, and data interaction and signaling time delay need 2 seconds, and telephone expenses show needs 0.8 second, amounts to 6.8 seconds consuming time.

Therefore, behind the end of conversation, the time delay that telephone expenses are issued to phone is longer, and the user need wait for the regular hour, and then has increased the person's on duty clearing time, has reduced user's the satisfaction and the utilance of phone.
