Description

A kind of charging method of wireless public telephone system

Technical field

The present invention relates to wireless public telephone system, relate in particular to a kind of charging method of wireless public telephone system.

Background technology

Wireless Pay Phone has appearred in the development along with the public telephone technology.Wireless Pay Phone is meant that public words adopt wireless access to go forward side by side to work words to charge, and in the reality operation, Wireless Pay Phone normally adopts Attended mode to act on behalf the family mode and runs.Act on behalf the family after opening an account on the public affairs words platform, get the Public CDMA WLL terminal from operator and carry on the work, the telephone subscriber acts on behalf the family and collects the certain amount of money of telephone subscriber according to the calling charge information that the Public CDMA WLL terminal shows after the enterprising words that work of Public CDMA WLL.

For the charging way of Wireless Pay Phone, the past mainly is to adopt wireless terminal charging and wireless switching network charging way.After the user used wireless terminal to converse, wireless switching network chargeed to this time conversation, and this expense is used for operator and carries out payment settlement with the charg`e d'affaires family.Simultaneously, wireless terminal also charges according to the Rate Plan that is provided with in advance and shows that this expense is used to act on behalf family and telephone subscriber's payment settlement.

The shortcoming of this implementation is:

A, owing to act on behalf family and telephone subscriber and adopt the terminal to charge to settle accounts, the people that the Public CDMA WLL terminal technology is known about can change the rate setting at Public CDMA WLL terminal, makes that acting on behalf the family can carry out the expense swindle;

B, clearing owing to pay in charg`e d'affaires family and operator employing back, the behaviors such as malicious owing fee at uncontrollable charg`e d'affaires family;

C, when needs are revised rate, need on each public telephone terminal, make amendment.

To above shortcoming, new-type wireless public telephone system adopts the mode of online charging usually at present.In the carrier network platform, build the Public CDMA WLL platform, the all-calls at Public CDMA WLL terminal all need be linked on this Public CDMA WLL platform through signatory or preceding mode of inserting access code.The Public CDMA WLL platform is responsible for public affairs and is talked about the subscription authentication of calling, continues, calls out a series of functions such as control, charging, clearing.When operation, adopt prepayment mode, acting on behalf the family needs at first on public affairs words platform, to open an account and prestore certain expense.Operator and the rate of acting on behalf the family and charg`e d'affaires family and telephone subscriber's rate rate is all in the enterprising administration-management reason of public affairs words platform.Behind end of calling, public words platform is acted on behalf the clearing of family account automatically, and generation telephone subscriber ticket is handed down to public telephone terminal.

Can find out that from last surface analysis the online charging mode not only can be avoided the telephone expenses swindle, and when needs were revised the charging rate, quantities was little and simple to operate.

The online charging mode need solve the technological point of two keys:

1. the control of the SOT state of termination.Public words platform need be controlled the calling at terminal, and after public telephone terminal on-hook or called phone on-hook, public words platform need obtain phone on-hook information timely and carry out disbursement and sattlement.

2. guarantee to take down speed.Public words platform needs being issued on the Public CDMA WLL terminal of this information prestissimo shown after calculating cost of the phone call information.This process generally need be no more than 5 second time.

Present online charging wireless public telephone system normally adopts intelligent network technology to realize that the SOT state of termination is to be controlled by mobile switching centre (MSC).After Public CDMA WLL hanging up terminal or called phone on-hook, MSC obtains caller or Called Onhook signaling from the mobile signaling protocol net, and it gives general phone service control point (SCP) through intelligent network signaling (INAP/WIN/CAMEL) notice.Public words SCP is handed down to Public CDMA WLL terminal through MSC with direct transfer application part (DTAP) message of A mouths such as service announcements message with ticket after obtaining caller or Called Onhook information.When the on-hook of called phone elder generation, adopt the list of passing on a message under the Traffic Channel; When the on-hook of Public CDMA WLL terminal elder generation, adopt the list of passing on a message under the PCH.

This mode has realized the specification requirement of online charging, but adopts DTAP message to issue ticket, and this message can't correctly resolved and show to common mobile module, need do the special exploitation of public words to mobile module, has improved Public CDMA WLL terminal cost.
