Overview

• Circuit Charging– Wireless Radio Telecommunications Non-Signaling Data Communication

DMH (Data Message Handler)– Pre-Paid Charging

• Packet Charging– cdma2000®1 Wireless IP Network– Packet Pre-Paid

• MMD Charging• MMS Charging

1 cdma2000® is the trademark for the technical nomenclature for certain specifications and standards of the Organizational Partners (OPs) of 3GPP2. Geographically (and as of the date of publication), cdma2000® is a registered trademark of the Telecommunications Industry Association (TIA‑USA) in the United

States.”

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.

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

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

June 2004 6

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

June 2004 7

Packet Charging

• Packet accounting information elements– Radio interface

– Signaling traffic

– Octet counts

June 2004 8

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

June 2004 9

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

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

June 2004 11

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.

June 2004 12

MMD Charging

• X.S0013-A v1.0 (4Q04) will align with 3GPP Release 6 IMS Charging

June 2004 13

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

June 2004 14

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

June 2004 15

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.
