Description
Technical field
The invention belongs to communication field, relate to a kind of cut-in method of public telephone, particularly a kind of intelligent public telephone fast access method.
Background technology
Traditional public telephone, adopted the terminal charging, only need carry out communication at the phone set terminal dial-in direct, as coin telephone, card phone, IC-card phone, these all are a kind of off-line systems, can't realize data centralization and control, have all drawbacks, for example: free call on sb. else's expense through illegal means, illegal operation, arrearage, rate dispute, rate are difficult to adjusting etc.
Along with the continuous development of intelligent network technology, produced based on the intelligent public telephone system of intelligent network technology.By on the intelligent public phone special-purpose terminal, dialing an access code automatically, will call out control and all transfer to IN service control point (SCP) and control, thereby realize central controlled online public telephone system.
Utilize intelligent network technology, realize intelligent public telephone operation system architecture as shown in Figure 3:
Among Fig. 3, Service Switching Point is responsible for professional access and operation exchange, and Service Control Point is responsible for professional control.Professional management is responsible in service management point (SMP), and service creation environment point (SCEP) generates service logic, and service data point (SDP) preserves business datum, and ip intelligent peripherals (IP) provide all kinds of resources.General calling is relevant with SSP, SCP, SDP and IP.By Signaling System Number 7, (INAP) controls according to intelligent network application protocol between SSP and the SCP.A typical operation flow is as follows:
The dialing of user's off-hook;
Calling Side exchange is issued SSP with initial address message by the Signaling System Number 7 net;
SSP initiates to start service order to SCP;
SCP carries out service logic control (as required, may need the participation of SDP and IP), request SSP acquisition of information;
SSP returns Address Complete Message and response message to originating switch;
SSP, collects the number of user's input, and reports SCP to the speech channel of setting up between the SSP by terminal;
SCP carries out FH-number transform (if necessary) and authentication, and indication SSP continues called;
SSP initiates a calling to callee side, with SSP and called speech channel connection;
SSP connects the speech channel of calling and called, converses;
User's on-hook, terminated call, SCP handles accordingly.
Application for a patent for invention " higher intelligent public telephone system (CN1222025) " discloses a kind of public telephone system---higher intelligent public telephone system of novel concept.This system is by stored-program control exchange, paging base station, voice mail, the IN service control point, dialup server (card sending system), router (networking interface), the software of supporting subordinate terminal equipment (the outdoor firm of anti-destruction ordinary telephone set, card dialer and socket) and bulky complex is formed.The defective of existing intelligent public telephone system is not still broken away from this invention, and existing intelligent public telephone system all adopts the two-stage dialing technology when the user inserts.The access code of system is transferred in dialing for the first time automatically by intelligent terminal, after access code is received by system, starting operation flow handles, then by broadcast, prompting phone user imports called number, and finish with a # keyboard mark number input, system will carry out call proceeding according to this number.Because the process that collects the digits of terminal and platform is twice, is commonly referred to as two-stage dialing.
The subject matter of the two-stage dialing technology of generally using in intelligent public telephone system is at present:
1) dialing does not meet people's custom that dials.Since after collecting called number, must a # keyboard sign of input end of input.And the user of public telephone is generally the crowd of flowing, and causes it to use inconvenience like this, thinks by mistake and can't connect and on-hook, causes communication resource waste.
2) twice access, actual turn-on time is longer.Do not dial the # keyboard if the user knows to add, also need 3 to 5 seconds interdigit time out stand-by period.So also prolonged the turn-on time of conversation.
3) owing to be once called number to be collected to carry out continuing second time after complete, can't realize analyzing by turn to called number, the item sign indicating number if the user dials the wrong number midway could be found routing issue after finishing with regard to must all dialling again, and actual service efficiency is lower.
