Description

A kind of mobile public telephone that can realize unattended duty

Technical field

The utility model relates to communication technique field, relates in particular to the mobile public telephone that can realize unattended duty.

Background technology

At present, the public affairs of unattended duty words mainly are made up of IC Card Telephone, card phone, coin telephone and prepayment account card type phone, the general PSTN net that directly inserts of the public words of this kind.Wherein the public words of card insert type are a kind of is directly to reduce the amount of money from card to realize fee administration, and another kind is realized fee administration by the backstage running.Such as Chinese patent application number 00106373 disclosed technology, it mainly is made up of intelligent public telephone terminal and intelligent net system, its communication mode is that data such as the card number of smart card and password, called number, the account number amount of money are communicated by telephone network and intelligent net system, intelligent net system adopts the dynamic password verification system, carry out the legitimate verification of card number and password, finish switched connection, cost of the phone call is deducted in the corresponding account number of database of intelligent network.It has solved the problem inaccurate, that traffic data is lost easily, security of system is bad of chargeing, but also exist terminal and system can not wireless access, terminal can not roam, whole system can not Unified coding etc. shortcoming.

The intelligent public telephone system that Chinese patent application number 02140480.1 discloses a kind of terminal phone can wireless access, can roam.Include: use management system one innings, office is connected and fixed the local telephone network local network with management system, realizes functions such as each local network office connection roaming, recall, dialing; Use transmitting terminal one innings, this transmitting terminal is by fixed network local telephone connection office management system, and built-in emission, reception antenna send information to office and send with the instruction of management system with management system or with office; One user terminal phone use the transmitting terminal wireless access with the wireless subscriber terminal phone with office, wireless terminal phone wireless access by signal send, the information of office of acceptance's usefulness wireless transmitting terminals, and be provided with independently number, password, account number.When the wireless subscriber terminal phone of this locality uses, the wireless subscriber terminal phone is automatically with the number of this machine, password, relevant informations such as account number send to office with system of the wireless transmitting terminals office of entering, office sends to public conversation platform with system, check the use identity of this machine by the public telephone platform, if it is legal, enter dialing, its expense is realized by system's commander's auto deduction, real time billing is chargeed accurately, if illegal, then refusal uses, simultaneously each wireless subscriber terminal phone account is unique, and by wireless subscriber terminal phone number independently, cipher control can prevent free call on sb. else's expense through illegal means effectively.But because this account and wireless subscriber terminal phone are corresponding one by one, then be applied to public words field, obviously can't realize the real time billing of unattended duty at each public words user.In addition, the public affairs of above-mentioned all unattended duties of mentioning words all can make telephone line connect by electronics or mechanical means, can not effectively prevent free call on sb. else's expense through illegal means.

The utility model content

The utility model provides a kind of can effectively prevent free call on sb. else's expense through illegal means, realizes the mobile public telephone of unattended duty.

The utility model be achieved in that be connected with key board, wireless communication module, peripheral hardware IC-card seat, device power supply (DPS) system on the master controller, from microcontroller, system parameters storage device and clock chip; From microcontroller, be connected with Chinese display module and calling generating device in addition, peripheral hardware antenna on the wireless communication module; Wherein peripheral hardware IC-card seat is connected with wireless communication module.

Adopted the mobile public telephone of realization unattended duty of the present utility model, be exactly in fact the SIM card in conventional mobile phone wireless network user identification cards such as (perhaps) UIM cards has been substituted original public affairs words card, like this when plug-in card not, so no matter the similar mobile phone that SIM card (perhaps wireless network user identification card such as UIM card) is not installed of mobile public telephone can't realize free call on sb. else's expense through illegal means by which kind of electronics or mechanical means.Mobile phone uses very universal now, when going out, the awkward situation that mobile phone electric weight deficiency sometimes can occur, this opportunity, the master can be nearby inserts his SIM card wireless network user identification cards such as (or) UIM cards in the mobile public telephone of the present utility model, do not need to buy separately public words card, just can realize communication, very convenient.
