Abstract
The invention provides a method for arranging calling detailed record (CDR) in CDMA prepayment service, applied in the condition that a user acts as the called and is not in the same region with a calling user, prearranging service identification information about prepayment service on home HLR (home location resister) and SCP, adding on-HLR configured service identification into the information transmitted by floor bureau MSC/SSP by VLR in HLR during establishing communication; the MSC/SSP receives the HLR-sent information and then extracts and stores the above-mentioned service identification; after the communication ends, as generating CDR detailed list, the floor bureau SSP firstly judges if the service information sent by the SCP has been received: if yes, according to the identification, arrange prepayment identification for CDR detailed list; otherwise judges if HLR-sent service identification has been stored: if yes, arrange prepayment identification for CDR detailed list according to the identification and otherwise defaultedly arrange the CDR detailed list as an after payment identification. As the SSP can not obtain service identification from the SCP, it can exactly arrange the CDR from HLR, thus assuring exact pre-charging.
Description
Technical field
The present invention relates to the intelligent network technology field that the target mode triggers in the cdma network, be meant the method that call detail record is set in a kind of CDMA prepayment service especially.
Background technology
In the communications field, traditional business is a post payment service, and in telex network, communication system produces call detail record (CDR), then calculates the final communication cost of user according to CDR.At present, it is detailed single that post payment service goes out CDR at the SSP of communication system, finally singly chargeed and deduct fees according to CDR is detailed by accounting system.
Also comprise prepayment service at present, by user's communication cost that prestores in advance, when telex network, communication system is carried out real-time deduction, and when the expense that prestores is not enough, communication service will stop, and continues to provide communication service after depositing sufficient expense once more.At present, prepayment service is chargeed, is deducted fees by SCP, and the detailed list of the CDR that SSP goes out only is used for the charging case of SCP is checked.
In the intelligent network that CDMA target mode triggers, SSP is provided with service identification in the detailed list of the CDR that is gone out, and default setting is the post payment service sign.When carrying out prepayment service, SCP is to SSP issuing service sign (DMH_SVCID), and SSP is changed to the prepayment service sign according to the DMH_SVCID that receives with the service identification in the detailed list of CDR.Accounting system analyzes after CDR contains prepayment service sign, can singly not deduct fees according to CDR is detailed.
In addition, in order to satisfy the multiple demand of IN service, may provide prepayment service and post payment service per family to same usefulness.For example, mobile virtual private network (MVPN) business is a prepayment service, MVPN user has a pre-payment account number in SCP, but because the user of MVPN can deactivate the MVPN business at any time, make the user between MVPN business and common post payment service, arbitrarily to switch, so each MVPN user exist prepayment service account number and post payment service account number simultaneously.
When there are these two kinds of paid services in a user, current what carry out is prepayment service if SSP can't identify the user, after then SCP crosses expense at the prepayment service button, the detailed list of CDR can be the back paying identification by default setting still, after causing accounting system to detect the back paying identification, deduct fees once more, form to call repeat deduct fees.
Fig. 1 is under the MVPN business of the intelligent network that CDMA target mode triggers, the user is as the call flow diagram under called and the situation of different office points with caller, describe as example, wherein the MSC/SSP of Originating Office represents with GMSC/SSP, and landing office is that the MSC/SSP of office point, called subscriber place represents with VMSC/SSP.
Step 101:GMSC/SSP receives calling subscriber's calling, triggering mobile terminals (Mobile_Termination) trigger, send position requests (LOCREQ) message to HLR, wherein LOCREQ contains charging identifier (BILLID) and triggers type (TRIGTYPE) parameter.
Step 102:HLR is to GMSC/SSP loopback location response (locreq) message, contain user data inventory (profile) in the locreq message, in profile, have and trigger address list (TRIGADDRLIST), dispose initial terminal (Initial_Termination), position (Location), called routing address on this TRIGADDRLIST inventory and can use triggers such as (Called_Routing_Address_Available), follow-up flow process is triggered successively according to triggering the address list content.
Step 103:GMSC/SSP triggers the Initial_Termination trigger, and the SCP transmission information that in the TRIGADDRLIST parameter, indicates detection request (ANLYZD) message, wherein the TRIGTYPE parameter among the ANLYZD indicates and has triggered the Initial_Termination trigger.
After step 104:SCP determines that account that the called subscriber has activated IN service and called subscriber has enough remaining sums, SCP detects response (anlyzd) message to GMS/SSP loopback information, and wherein the DMH_SVCID parameter among the anlyzd has indicated performed IN service.
Step 105:GMSC/SSP triggers the Location trigger, and sends LOCREQ message to HLR, wherein indicates by the TRIGTYPE parameter among the LOCREQ and has triggered the Location trigger.
Step 106:HLR determines that call treatment should continue, and send route requests (ROUTREQ) message to VLR, change ROUTREQ message before the VLR and give VMSC/SSP, VMSC/SSP distributes interim local directory number (TLDN) and returns to VLR by route response (routreq) message, and VLR is transmitted to HLR.HLR sends locreq message to GMSC/SSP, returns terminal list (TERMLIST) information, and order is routed to the called subscriber.
Step 107:GMSC/SSP prepares to set up and calls out, and triggers the Called_Routing_Address_Available trigger, and send ANLYZD message to give SCP.
Step 108:SCP loopback anlyzd message, return results is given GMSC/SSP.
Step 109:GMSC/SSP is established to called subscriber's calling, and behind the called subscriber answer, the MSC triggering terminal is replied (T_Answer) trigger, send and replys (TANSWER) message to SCP, and SCP begins to charge, and both sides converse.
Step 110: behind the end of conversation, user's on-hook, VMSC/SSP triggering terminal (T_Disconnect) trigger of taking out stitches, and send (TDISCONNECT) message of taking out stitches and give SCP, include the information of calling subscriber's on-hook.
Step 111:SCP stops to charge, and to VMSC/SSP loopback response (tdisconnect) message of taking out stitches, the DMH_SVCID parameter that wherein is provided with among the tdisconnect has indicated performed IN service.
Step 112:SSP terminated call output CDR is detailed single, and the DMH_SVCID that issues according to SCP, and CDR is set to the pre-payment sign accordingly.
From above-mentioned flow process as can be seen, when MVPN user does called, and with the calling subscriber not in same when office, landing office SSP knows that this calling is that the unique channel of MVPN prepayment service is when service ending, SCP is handed down to the entrained DMH_SVCID of T_Disconnect message of landing office SSP, indicates this calling and is prepayment service.When SSP did not correctly receive this T_Disconnect response message, the detailed single post payment service that will be set to of the CDR of output identified, and causes SCP after pre-payment account number button is crossed expense, and accounting system also can be deducted fees on the payment account of back once more.
SCP also can be under other abnormal conditions correct loopback T_Disconnect response message, and for example, when SCP issues and calls out Indication message (CCDIR) and remove to inquire about current call state, SSP reports the T_Disconnect request message, calling among the SSP at this moment is in release condition, can't correctly handle CCDIR message, then can loopback SCP error response message, and SCP receives error response message in the process of waiting for SSP response CCDIR message, then abandon the T_Disconnect request message that SSP reports, winding-up, SCP also deducts fees on the pre-payment account number.Because the SCP winding-up can not echo to SSP again should, therefore SSP will can't obtain the T_DISCONNECT response message of SCP according to operation flow, SSP causes accounting system to repeat to deduct fees owing to can not know the detailed back paying identification that singly is defaulted as of CDR that DMH_SVCID makes output like this.
Summary of the invention
In view of this, main purpose of the present invention is the method that CDR is set in a kind of CDMA prepayment service is provided, make when prepayment service, SSP can't be normally when SCP obtains service identification, can obtain service identification from HLR CDR correctly is set, thereby it is correct to guarantee to charge.
The method of call detail record CDR is set in the CDMA prepayment service of the present invention, be applied to the user as called, and with the calling subscriber not in the situation of same office point, on HLR, SCP, dispose the service identification information of prepayment service in advance, further comprising the steps of:
In the information that landing office MSC/SSP transmits, increase the service identification that is disposed on the HLR at HLR by VLR; Landing office MSC/SSP extracts and preserves described service identification after receiving the information of described HLR transmission;
Behind the end of conversation, it is detailed when single that landing office SSP produces CDR, and the service identification that receives according to landing office MSC/SSP is provided with the detailed single pre-payment sign of CDR.
Wherein, when end of conversation, SCP sends to landing office MSC/SSP by the response tdisconnect message of taking out stitches with the service identification that SCP goes up configuration, this method further comprises: landing office SSP at first judges whether to receive the service identification that SCP issues, if then the detailed single pre-payment sign of CDR is set according to this sign, otherwise judge whether to preserve the service identification that HLR sends, if then the detailed single pre-payment sign of CDR is set, otherwise the detailed single default setting of CDR is the back paying identification according to this sign.
Wherein, the information of described HLR transmission is route requests ROUTREQ message.
By said method as can be seen, use the present invention, in the flow process of the intelligent network pre-payment service that CDMA target mode triggers, under some abnormal conditions, SSP can't be normally when SCP obtains DMH_SVCID, SSP can obtain service identification from the ROUTEQ information that HLR issues, guarantee correctly to be provided with the DMH_SVCID in the detailed list of CDR, thereby guaranteed the correct of charging.And SSP is when being provided with the service identification of the detailed list of CDR, and the service identification of preferentially selecting SCP to issue as if the service identification of just not selecting to issue from HLR, thereby influences minimum to existing procedure.In addition, obtaining service identification from SCP is in the end of conversation stage, is before setting up conversation and obtain service identification from HLR, and this makes the abnormal conditions that taken place can not obtain service identification to SSP midway and impacts.
