Embodiment
As shown in Figure 1, wireless intelligent public telephone of the present invention system comprises a plurality of portable terminals 12 and service control point (Service Control Point, SCP) 11, a plurality of portable terminals 12 are by base station (BaseStation, BS) and Service Switching Point (Service Switch Point, SCP) 14 are connected with service control point 11 communications.Service control point 11 also is connected with attaching position register (HLR), ip intelligent peripherals (IP), mobile switching centre (MSC) etc. in addition, forms intelligent network jointly.
As shown in Figure 3, be the flow chart of the implementation method of wireless intelligent public telephone of the present invention.In conjunction with Fig. 2, portable terminal 12 at first receives the input of fare card behind off-hook, and receive the input called out the numbers, wherein the input of fare card can be the account number cipher of account number generation group card (can comprise configuration informations such as access code, speech selection, account number, password) or keyboard input etc., called out the numbers and then imported by keyboard, at this, called out the numbers and directly do not uploaded, but be temporary in portable terminal 12 (step S31).Portable terminal 12 is uploaded access code then, triggering intelligent network service, and it is called out the numbers the master of portable terminal 12 by base station 13 and Service Switching Point 14 and uploads to Service Switching Point 11 and verify (step S32).11 pairs of calling mobile terminals 12 of service control point verify, judge this calling mobile terminal 12 whether registered (step S33).If calling mobile terminal 12 is unregistered, then by checking, service control point 11 does not issue error message to calling mobile terminal 12, and portable terminal 12 prompting error messages are as " phone is unregistered, can not use this business ".
If portable terminal 12 is by checking, be that calling mobile terminal 12 is registered, then service control point 11 returns to portable terminal 12 and passes through validation signal, and portable terminal 12 receives passing through of returning and uploads fare card information behind the validation signal, as " A+ category of language+card classification+card number+# " (step S34).Service control point 11 and portable terminal 12 carry out dynamic fare card checking (this step will be described in detail at Fig. 4) (step S36).
If fare card is by checking, then service control point 11 issues the balance amount information of fare card, and as " A3+ remaining sum+A ", the quilt that portable terminal 12 will be kept in is called out the numbers and uploaded to service control point 11, service control point 11 connects terminal called, and communication process is chargeed how to monitor (step S38).If the fare card authentication failed, then service control point 11 issues error message, and prompting enters the password update routine, and portable terminal 12 is imported new password twice by keyboard, and service control point 11 is revised the password (step S37) of fare card automatically.
When service control point 11 detected portable terminal 12 or terminal called on-hook, service control point 11 stopped to charge, and issued account card remaining sum and this duration of call " the A4+ remaining sum+A+ duration of call+A " information once more.In addition, when Sorry, your ticket has not enough value on the fare card, service control point 11 also can pass through the information of portable terminal 12 balance amount prompting deficiencies, and finished conversation in advance.
As shown in Figure 4, be the flow chart of charging card information verification step among Fig. 3.During the fare card checking, service control point 11 at first issues encryption key to calling mobile terminal 12, as " A1+ key (6)+A " (step S41).After calling mobile terminal 12 is received complete encryption key, encrypt (step S42), and the result that will encrypt " A+ password (encrypting the back)+# " uploads with several cryptographic algorithm in accordance with regulations after password in encryption key and the IC-card and the account number.Simultaneously the identical cryptographic algorithm of service control point 11 is encrypted (step S43) to identical data, and compares checking (step S44) with Crypted password that the calling mobile terminal of receiving 12 is uploaded.If two results (Crypted password) are identical, represent that then fare card passes through checking, execution in step S38; If two results are inequality, then execution in step S37.
