Accompanying drawing explanation
Fig. 1, Fig. 2 and Fig. 3 are embodiment of the inventive method, and P-CSCF network element carries out the message flow chart signal of charging to IMS multimedia peer to peer session in offline charging mode, wherein:
Fig. 1 is the message flow chart signal of call establishment stage;
Fig. 2 is the message flow chart signal of media switch step;
Fig. 3 is the message flow chart signal in end of calling stage.
Embodiment
Below by the concrete application example shown in Fig. 1, Fig. 2 and Fig. 3, further illustrate and how use the above-mentioned AVP structural information of expanding in Diameter charging message structure, carry out CDR sorting association, thereby realize IMS multimedia peer to peer session service billing.
First, this concrete multimedia peer to peer session application scenarios is that P-CSCF is configured to into charging, the terminal UE of Calling Side SIP signaling type, and it belongs to the virtual signaling grouping that is numbered 1000 on P-CSCF, below concrete charging flow is described step by step:
As shown in Figure 1:
Step S1:P-CSCF network element is received the conversation initial request message that Calling Side terminal UE is sent;
Step S2:P-CSCF network element forwards session initial request message to callee side;
Step S3:P-CSCF network element is received the response message that callee side is sent;
Step S4:P-CSCF network element is transmitted to Calling Side terminal UE by response message;
Step S5:P-CSCF network element sends initial charging request message ACR[Start to off-line data function CDF entity], this charging request message is with Signal-Group, Signal-Type and the self-defined AVP field of Billing-Leg, and the concrete fill substance of P-CSCF network element is as follows:
In Signal-Group field, insert the virtual signaling packet numbering 1000 that Calling Side terminal UE belongs to P-CSCF; In Signal-Type field, insert 0, represent that signaling type is Session Initiation Protocol type; In Billing-Leg field, insert 0, represent that charge type is for entering to charging;
Meanwhile, in IMS charging message form, existing timestamp field is filled in the time at that time;
Step S6:CDF entity is received after the charging request message that P-CSCF network element sends, and is that 1 P-CSCF CDR charging bill is opened in this session, and by initial charging request message content update charging bill content;
Step S7:CDF entity returns to charge response message ACA to P-CSCF network element;
As shown in Figure 2:
Step S8:P-CSCF network element is received the media handover request message that Calling Side terminal UE is sent, and request switches to 7231 type of media by former 711U type of law media;
Step S9:P-CSCF network element forwards media handover request message to callee side;
Step S10:P-CSCF network element is received the response message of the media handover request that callee side is sent;
Step S11:P-CSCF network element is transmitted to Calling Side terminal UE by the response message of media handover request;
Step S12:P-CSCF network element detects conversation media face variation has occurred, so send Intermediate Charging ICH request message ACR[Interim to off-line data function CDF entity], this charging request message is with the self-defined AVP field of Signal-Group, Signal-Type, Billing-Leg and List-Of-Media-Traffic-Data-Volumes, and P-CSCF network element is as follows according to the concrete fill substance of the actual value of session:
In Signal-Group field, insert the virtual signaling packet numbering 1000 that Calling Side terminal UE belongs to P-CSCF; In Signal-Type field, insert 0, represent that signaling type is Session Initiation Protocol type; In Billing-Leg field, insert 0, represent that charge type is for entering to charging;
For List-Of-Media-Traffic-Data-Volumes creates 1 member's item, and:
In Media-Traffic-Change-Condition field under this member's item, insert 0, presentation medium switch reasons has triggered this Media Stream scale and has reported;
In Media-Traffic-Change-Time field under this member's item, insert the time at that time;
