12. All Rights Reserved © Alcatel-Lucent 2010 12 | IeCCF Customer Marketing Presentation | February 2010 Functional scope of Alcatel-Lucent IeCCF Main features Alcatel-Lucent IeCCF includes two modules defined in standard:  CDF- Charging Data Function  CGF- Charging Gateway Function Each IMS node (core or application servers) generates charging events toward CDF:  Contain the accounting information according to network-resources use  Based on Diameter Rf interface (ACR/ACA) CDF main features:  Collecting Rf charging events from various nodes for a single IMS session  Aggregation (full CDRs/partial CDRs)  Correlation  Generating CDRs CGF main features:  CDR persistent storage  CDR reprocessing: error handling and reformatting  CDR file routing and filtering: criteria for separate CDR files  CDR file management: file creation, opening and deletion Alcatel-Lucent IeCCF = CDF plus CGF

13. All Rights Reserved © Alcatel-Lucent 2010 13 | IeCCF Customer Marketing Presentation | February 2010 Alcatel-Lucent IeCCF key features Aggregation: aggregates partial CDRs of one session or call from the same node, cumulating the value of certain fields and linking them by a specific identifier Correlation: correlates CDRs from multiple NEs to a complete rateable record:  Intradomain correlation: on network-charging identifier for charging information from different NE of one domain  Interdomain correlation: cross-domain correlation CDR routing and filtering: policy engine-based mechanism to route CDRs to different CDR files and file directory; also CDR files are routed to different business applications, including BS, CRM and FMS Prebiller: interfaces with OCS rating engine and calculates call costs for correlated CDRs CDR enrichment: enriches subscriber information to CDR records by, for example, querying HSS Supplementary service:  Supports VoIP supplementary services CDR extensions  Supports VoIP, IMS roaming and handover CDR extension Flexible workflows GUI for defining flexible workflows Robust overload control mechanism Preserve CDRs against failures and losses

16. All Rights Reserved © Alcatel-Lucent 2010 16 | IeCCF Customer Marketing Presentation | February 2010 Alcatel-Lucent IeCCF Why Alcatel-Lucent IeCCF key element for any IMS/LTE offer? Mandatory for CDR generation  Contrary to legacy networks where each node may generate their own CDRs, in IMS/LTE core there is no tracking of the network-resource use without the Alcatel-Lucent IeCCF Why not use only a real-time approach and not use Alcatel-Lucent IeCCF? Alcatel-Lucent IeCCF still mandatory for interconnect charging:  As per 3GPP specification, some IMS nodes do not support real-time charging trigger Ro, including border and gateway functions P/I-CSCF, BGCF and MCGF  Still CDR are mandatory for interconnect-settlement processing (interoperator) Even in a network where real-time, online charging is the preferred method there will still be viable requirement to use CDRs for items such as data warehousing and clearance-house interfaces. Some large networks may also need offline charging, requiring the Alcatel-Lucent IeCCF. Alcatel-Lucent IeCCF is mandatory for any IMS/LTE core business Alcatel-Lucent IeCCF supports Evolved Packet Core (LTE Networks)
