Abstract

This invention discloses a method for calling called payment phone service users by pre-payment service (PPC) users, in which, after a mobile service switch center (MSC) triggers the trigger of specific-called-party-digit-string of a called FPH user, it eliminates the trigger of the PPC user and carries out the flow of the called payment phone service.

Description

The method of pre-payment service user callingcalled payment telephone service party

Technical field

The present invention relates to the call technology in the communication system, relate in particular to a kind of prepayment service (Pre-PaidCharging, PPC) customer call transferred charge call business (Frephone, FPH) user's method.

Background technology

PPC is meant the user by paying certain fund or buy fixedly mode such as face amount rechargeable card, and injection fund in self account is paid the business of cost of the phone call in advance.When call setup, decision is that receipt of call or refusal are called out according to the remaining sum on the user account in system; In calling procedure, system's real time billing is also deducted cost of the phone call from user account; When user balance was not enough, system cuts off called out and plays corresponding recorded announcement.

FPH is a kind of business that embodies charging way, and its principal character is called payment cost of the phone call, and caller need not be paid cost of the phone call.After the user applies open F PH business, if this FPH user of other customer call is arranged, then the cost of the phone call that is produced in the calling procedure is paid by FPH user.Because these are called out caller is free, therefore be commonly called freephone.

When PPC customer call FPH user, calling priority and will being higher than the FPH business of PPC business that is to say, handles the PPC business earlier, handles the FPH business again.Referring to shown in Figure 1, in the prior art, PPC customer call FPH user's flow process mainly may further comprise the steps:

Step 101: caller PPC user is initiated to called FPH user's calling.

Step 102: serving mobile switching center (Mobile Switching Center, MSC) trigger authentication (Origination_Attempt_Authorized) trigger that starts, business control nodes (Service Control Point to association, SCP) be that prepayment service Control Node (PPC SCP) sends origination request (ORREQ) message, inquiry PPC user balance whether be on the occasion of.

After step 103:PPC SCP receives the service MSC ORREQ message of sending, MSC returns response (orreq) message that starts to service, when the PPC user balance be on the occasion of the time, service key (DMH_SVCID) parameter of in orreq message, carrying expression PPC activation of service, indicating call is proceeded.

Step 104: service MSC triggers special number (Specific_Called_Party_Digit_String) trigger, is that transferred charge call business control nodes (FPH SCP) sends analysis request (ANLYZD) message to the SCP of association.

After step 105:FPH SCP receives ANLYZD message, this message is analyzed, and to analyzing responding (anlyzd) message of serving MSC transmission carried terminal tabulation (TERMLIST), DMH_SVCID and charging identifier (BILLID) parameter, wherein, TERMLIST indicates the routing iinformation of this call setup, DMH_SVCID indication FPH activation of service, it is FPH that BILLID indicates the ticket type of this calling.

Step 106: after service MSC receives anlyzd message, preparation is established to called route, at this moment trigger the caller routing address and can get (Calling_Routing_Address_Available) trigger, to the SCP of association is that PPC SCP sends the ANLYZD message of carrying the BILLID parameter, whether inquiry PPC user balance enough initiates this calling, wherein, to indicate the ticket type of this calling be FPH to BILLID.

Step 107: be collect call because this is called out, therefore, after PPC SCP received ANLYZD message, MSC returned anlyzd message to service, and indicating call is proceeded.

Step 108: MSC is according to the anlyzd message that FPH SCP sends in service, is established to called route.

Step 109: after route is set up, called to service MSC echo reply.

Step 110: service MSC triggers and replys (O_Answer) trigger, is that (OANSWER) message is replied in PPC SCP transmission to the SCP of association.

OANSWER message is indication beginning charging information, but is collect call because this is called out, and therefore, PPC SCP can not charge to caller here; After PPC SCP receives OANSWER message, hold consultation, realize the operation of freephone with FPH SCP.

Step 111: caller finishes conversation.

Step 112: service MSC triggers (O_Disconnect) trigger of taking out stitches, to the SCP of association is that PPC SCP sends the request of taking out stitches (ODISCONNECT) message, indication stops to charge, and comprises parameters such as calling out release cause, trigger type (TRIGTYPE), date in this message.

After step 113:PPC SCP receives ODISCONNECT message, hold consultation, stop the charging of this calling, and return response (odisconnect) message of taking out stitches to service MSC with FPH SCP.

Step 114: service MSC finishes this calling.

From PPC customer call FPH user's shown in Figure 1 flow process as seen, what trigger assembling of the prior art was taked is the fit of trigger before keeping, promptly when assembling new trigger, trigger before keeping will not be removed, that is to say, the trigger mutually noninterfere of calling and called, service MSC whenever detects a trigger and can trigger, call flow is comparatively loaded down with trivial details, under the heavier situation of present switch burden, this makes the matter worse beyond doubt, has further increased the weight of the burden of switch; In addition, realize called charging through consultation between PPCSCP and the FPH SCP, this charging way is comparatively complicated, causes the generation of charging error situation easily.

Summary of the invention

In view of this, the object of the present invention is to provide a kind of PPC customer call FPH user's method, simplify call flow and charging way.

For achieving the above object, technical scheme provided by the invention is as follows: after service MSC triggers FPH user's Specific_Called_Party_Digit_String trigger, remove PPC user's trigger, carry out the flow process of transferred charge call business.

This scheme specifically may further comprise the steps:

After A, service MSC trigger the Specific_Called_Party_Digit_String trigger, send analysis request ANLYZD message, and remove PPC user's trigger to transferred charge call business control nodes FPH SCP;

After B, FPH SCP receive ANLYZD message, send analyzing responding anlyzd message to service MSC, service MSC is established to FPH user's route according to the anlyzd message of receiving;

C, service MSC trigger and reply the O_Answer trigger, send to FPH SCP and reply OANSWER message;

D, service MSC trigger the O_Disconnect trigger of taking out stitches, and send the request ODISCONNECT message of taking out stitches to FPH SCP;

After E, FPH SCP receive ODISCONNECT message, return the response odisconnect message of taking out stitches to service MSC, service MSC finishes this calling.

This shows, the fit of trigger before the trigger assembling among the present invention has been taked to remove, make in PPC customer call FPH user's process, PPC user only need trigger the Origination_Attempt_Authorized trigger, and need not trigger other trigger of PPC user again, as Calling_Routing_Address_Available trigger, O_Answer trigger and O_Disconnect trigger, simplified call flow, alleviated the switch burden; And, need not among the present invention to realize called charging by the negotiation between PPC SCP and FPH SCP again, make charging way be simplified.

Embodiment

For making purpose of the present invention, technical scheme and advantage clearer, the embodiment that develops simultaneously with reference to the accompanying drawings is described in further detail the present invention.

As seen from Figure 1, call out in FPH user's the process the existing P pc user, MSC is after having triggered the Specific_Called_Party_Digit_String trigger in service, also will continue to trigger PPC user's Calling_Routing_Address_Available trigger, whether inquiry PPC user balance enough initiates this calling; Trigger the O_Answer trigger, indication PPC SCP begins PPC user is chargeed; Trigger the O_Disconnect trigger, indication PPC SCP stops PPC user is chargeed.But in fact, because PPC customer call FPH user is a collect call, caller need not to bear calling charge, so the process of Calling_Routing_Address_Available trigger, O_Answer trigger and O_Disconnect trigger that triggers there is no practical significance.

Basic thought of the present invention is: in PPC customer call FPH user's process, after service MSC triggers FPH user's Specific_Called_Party_Digit_String trigger, remove PPC user's trigger, carry out the flow process of transferred charge call business.

Referring to shown in Figure 2, PPC customer call FPH user's flow process mainly may further comprise the steps in the present embodiment:

Step 201: caller PPC user is initiated to called FPH user's calling.

Step 202: service MSC triggers the Origination_Attempt_Authorized trigger, sends ORREQ message to PPC SCP.

After step 203:PPC SCP received the service MSC ORREQ message of sending, MSC returned orreq message to service, when the PPC user balance be on the occasion of the time, in orreq message, carry the DMH_SVCID parameter of representing the PPC activation of service, indicating call is proceeded.

Step 30 1,202 is consistent with prior art with 203, gives unnecessary details no longer one by one here.

Step 204: service MSC triggers the Specific_Called_Party_Digit_String trigger, sends ANLYZD message to FPH SCP, and removes PPC user's trigger.

In the present embodiment, the fit of trigger before the trigger assembling is taked to remove, promptly when assembling new trigger, trigger before removing, that is to say that MSC is after having triggered FPH user's Specific_Called_Party_Digit_String trigger in service, removes PPC user's trigger, in follow-up call flow, no longer trigger PPC user's trigger.Removed after PPC user's the trigger, subsequent voice calls flow process in the present embodiment is consistent with the flow process that FPH user calls out in domestic consumer, and service MSC can not trigger PPC user's Calling_Routing_Address_Available trigger, O_Answer trigger and O_Disconnect trigger again.

After step 205:FPH SCP receives ANLYZD message, this message is analyzed, and sent the anlyzd message of carrying TERMLIST, DMH_SVCID and BILLID parameter to service MSC.

Step 206: after service MSC receives anlyzd message, be established to called route according to the anlyzd message of receiving.

Step 207: after route is set up, called to service MSC echo reply.

Step 208: service MSC triggers the O_Answer trigger, is that FPH SCP sends OANSWER message to the SCP of association.

Step 209: caller finishes conversation.

Step 210: service MSC triggers the O_Disconnect trigger, triggers, and be that FPH SCP sends ODISCONNECT message to the SCP of association, indication stops to charge, and comprises parameters such as calling out release cause, TRIGTYPE, date in this message.

After step 211:FPH SCP receives ODISCONNECT message, stop the charging of this calling, and return odisconnect message to service MSC.

Step 212: service MSC finishes this calling.

As seen, method provided by the present invention can be simplified call flow, alleviates the switch burden, simplifies the charging way of calling out.

The above has carried out further detailed description to purpose of the present invention, technical scheme and beneficial effect; institute is understood that; the above is not in order to restriction the present invention; within the spirit and principles in the present invention all; any modification of being made, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
