Description
Technical field
The present invention relates to the ticket generation technique, relate in particular to a kind of method and system of segmentation ticket.
Background technology
In the communication network that third generation partner program (3GPP, 3rd Generation Partnership Project) is described, charge system is one of its important functional part, is the important leverage that operator realizes business revenue.Its major function is as described below:
Fig. 1 is the composition structural representation of charging functional entity in the 3GPP network, as shown in Figure 1, charging triggering function (CTF, Charging Trigger Function) be embedded in 3GPP IP Multimedia System (IMS, IP Multimedia Subsystem) each network element (comprises the Access Layer network element, the key-course network element, the operation layer network element) in, the major function that CTF realizes is, operating position according to the Internet resources that monitor, carry out the collection of charge information, and send to charging data function (CDF by Rf interface (Offline Charging Reference Point), Charging Data Function), the major function of CDF is, receive the accounting request (ACR that CTF sends, Accounting Request) message, be configured to charging data record (CDR, Charging Data Recording), and send to Charging Gateway Functionality (CGF, Charging Gateway Function) by the Ga interface, the major function of CGF is the CDR that receives from CDF to be carried out store and management, and by Bi, the CDR file is sent to billing domain (BD, Billing Domain).
In actual session, Session Time may continue the long period, such as several hours even several days.For the charging center, if only conversation end is just exported ticket, and the front CTF of conversation end or CDF have occured extremely, and the ticket of so whole session can not generate or produce extremely, cause the charging loss.If long session being fixed the ticket of time step cuts apart, such as the session more than 30 minutes all comes the output ticket according to the step-length of 30 minutes, so when above-mentioned abnormal conditions, can export take 30 minutes partial CDRs as unit, the charging center can be collected the expense of partial CDR accordingly, to reduce the loss of charging.
In actual session, the user may repeatedly use supplementary service or change media in conversation procedure, switches, carries out call waiting etc. such as carrying out audio frequency and video.For the session of this use supplementary service or media change, the charging center is necessary to carry out the ticket cutting according to media and supplementary service information.When switching such as the generation audio frequency and video, the Voice ﹠ Video session may need to export respectively ticket, because the rate that the Voice ﹠ Video session is collected is different; When carrying out Call Waiting, Call Waiting session during this period of time is free of charge or charges less.Therefore, carry out ticket with supplementary service or media change and cut apart, be conducive to accurate charging.
In actual offline charging, also has the demand of quasi real time charging, to reach the control of user credit amount.This demand needs shorter time step to carry out ticket and cuts apart, and just need to export a ticket such as 5 minutes.
In conversation procedure, also may be because user's movement causes time zone, user place to change, the session of different time zone also will be divided into different tickets in this case, because it may be different putting at the same time at local zone time corresponding to different time zone, and different local zone times may corresponding different period rates.Cut apart and carry out ticket according to the time zone switching, can improve the accuracy of charging.
By above analysis as can be known, cut apart if can carry out neatly ticket, be conducive to simplify the processing of charging center, can satisfy accurately and the quasi real time demand of charging, so that better billing of services to be provided.
Fig. 2 is the schematic diagram that in conversation procedure, CDF generates the CDR process, as shown in Figure 2, show the process that CDF in the conversation procedure described in 3GPPTS32.260 generates CDR: CTF sends ACR[Start to CDF when session begins], send ACR[Stop during conversation end], trigger ACR[Interim according to session initiation protocol (SIP, Session Initiation Protocol) event etc. in session]; CDF receives ACR[Start] time open ticket, receive ACR[Interim] time upgrade ticket, receive ACR[Stop] time close ticket.But for the partial CDR (Partial CDR) that how to generate after ticket is cut apart, 3GPP does not relate to, current do not have yet can reference technical scheme.
above-mentioned timing segmentation ticket, business changes segmentation ticket, the time zone changes the demand of segmentation ticket, can receive corresponding ACR[Interim by CDF] time output ticket realize, but have following problems: 3GPP has defined ACR and can have been triggered by which SIP method or isup message, and ACR comprises SIP-Method AVP and records concrete SIP method, but 3GPP does not define the property value of the concrete reason that triggers the SIP method to (AVP, Attribute Value Pair), such as, some ACR[Interim] because changing, business is triggered, some ACR[Interim] be triggered because reaching the restriction duration.So CDF receives ACR[Interim] time can't judge that this is which kind of charging condition changes the ACR that triggers, thereby can't determine whether the output ticket.As seen, existing charging method can not determine how charging bill is cut apart, and how to realize that ticket cuts apart.
