3. June 2004 2 Circuit Charging Wireless Radio Telecommunications Non-Signaling Data Communication DMH (Data Message Handler) –N.S0026-A Supports X.S0004-E Features and Capabilities Wireless Intelligent Network (WIN) Services Support home system value added services –N.S0026-A Objectives Transfer subscriber usage information in near real-time from serving to home system Autonomous call detail delivery transfers subscriber activity and facility usage measurement records with no acknowledgment. Autonomous call detail delivery with certification transfers records containing subscriber activity and facility usage measurements with acknowledgement and keeps track for auditing purposes.

4. June 2004 3 Circuit Charging DMH (continued) –N.S0026-A Methods Request rating and call detail information Compile intersystem accounting for accumulated usage Request intersystem accounting –N.S0026-A Information Elements Call attempts, toll access, feature activation/usage (home and visited) Call delivery attempts Air channel usage (analog, digital, encrypted digital, facsimile, data) Intersystem tandem trunk usage Authorization periods WIN service logic invocations WIN special resource usage

5. June 2004 4 Circuit Charging Pre-Paid Charging –Pre-paid Charging (N.S0018-0 v1.0) Circuit voice service WIN services –Pre-paid Charging Enhancements (X.S0010-A v1.0) Circuit data service Short Message Service

6. June 2004 5 Packet Charging cdma2000 Wireless IP Network –X.S0011-C supports Transport (bearer) layer accounting Accounting per IP Address/Service instance –Each session (Simple IPv4, Mobile IPv4, Simple IPv6) accounted for individually –Accounting record generation PDSN generates records Includes information from RAN Sent to AAA over Radius interface

7. June 2004 6 Packet Charging Packet accounting information elements –Radio interface –Signaling traffic –Octet counts

8. June 2004 7 Packet Charging Packet Pre-paid –Introduced in X.S0011-C –Based on traffic volume or connection duration –Managed by either PDSN or Home Agent –Includes sessions active during tariff switches

9. June 2004 8 Packet Charging Future enhancements for X.S0011-D –Support for additional capabilities Hotlining WLAN Mobile IPv6 –Support for correlation between bearer and application layer accounting

10. June 2004 9 MMD Charging X.S0013-007 IMS Charging Architecture –Charging based on Events (content based charging) Time Resource usage –Charging data generated by Session charging function Bearer charging function Event charging function –Relayed through AAA to billing systems

11. June 2004 10 MMD Charging X.S0013-008 IMS Accounting Protocol –Uses Diameter to AAA for off-line charging ECF for on-line charging –Charging information elements Application Server Authorized QoS Calling/Called Party Address Event Type Etc.

12. June 2004 11 MMD Charging X.S0013-A v1.0 (4Q04) will align with 3GPP Release 6 IMS Charging

13. June 2004 12 MMS Charging Planned for X.S0016-B v1.0 –May be part of joint effort with OMA Will be aligned with 3GPP Release 6 MMS Charging –MM8 for Pre-paid –MM9 for Real time

14. June 2004 13 MMS Charging Charging data generated by –MMS Relay/Server generates charging data Upon message receipt/delivery Reverse charge request for MMS response –MMS Value Added Service (VAS) Application Upon message receipt/delivery from/to MMS Relay/Server

15. June 2004 14 MMS Charging MMS charging information elements –MMS Message ID –Message size –Charging indicator (e.g., pre-paid, reply charge) –Recipient address –Sender address –Conversion type and media –Etc.
