3 A Tour Guide for the Convergent Billing Journey Ready for a break: Reasons to start this journey Before we start: Let s have a look at the environment Tour planning: Which route to take Arrived: Where to go next
4 Ready for a break: Reasons to start this jouney
5 Typical Drivers to Seek a New Convergent System We have outgrown We cannot launch our current system: We cannot take on new We cannot products launch because It is it too slow and the business no. customers We want to take on takes convergent too long to change of products becomes because they want corporate customers prepaid the billing / postpaid system(s) unmanageablepostpaid and we are worried BUT we about cannot credit create risk products complex billing hierarchies We need to start putting systems in place that support revenue sharing We have too many systems We have in place. to getwe need revenue to rationalize leakage under and reduce control CapEx/OpEx
6 What is Convergent Billing all about?! Introduction of new & extended functionality for all customers! Gaining enhanced flexibility & improved time-to-market! Replacing (reducing) multiple systems in the area of Billing
7 Convergent Billing for all Customer Segments simple complex Private / Residential SINGLE USER FAMILIES Business SoHo / SME CORPORATE
8 Convergent Billing - Single Users Use Cases:! Multiple pre-/ postpaid balances & accounts (one aggregated statement/invoice)! Switch between prepaid & postpaid: - via active customer interaction - automated via configuration! Personal spending limits! Personalized offers & subscriptions (also for prepaid)! Cross service & recharge promotions! Real-time notifications & announcements (also for postpaid)
9 Convergent Billing - Families Use Cases:! Family Bundles (e.g. 300 free voice minutes)! Family bill & budget control (shared accounts with spending limit)! Postpaid reloads prepaid (automated & manual top-up)! Family bonus (joint collection & redemption)! Called party / 3rd. party pays - pay for me ( daughter calls father > father pays ) ( daughter calls brother > father pays )
10 Convergent Billing - Business Customers! Flexible Customer Hierarchies & Multiple Accounts Company Private Account Department 1 Department 2 User 1 User 2 User 3 User 4 User 4 Prepaid All Services Postpaid All Services Prepaid Data Prepaid Data Corporate Postpaid Private Voice Postpaid Voice Postp. Voice Corporate Prepaid Private Data
11 Convergent Billing - Business Customers Use Cases:! Definition of hierarchies & departments with different payment methods! Hierarchical cost / budget control! Calls between colleagues can be assigned to company accounts (payment method based on dialed number)! Calls outside the office hours can be assigned to private account! Multiple accounts with prepaid or postpaid payment (real-time cost control: per service/location)
12 Benefits! Lower OPEX! Less resources with reduced skill set! Identical configuration for all services, products and tariffs! Less integration points! Streamlined processes! Reduced fraud and revenue leakage! Less and homogeneous hardware to maintain! Higher Flexibility! Shorter time to market for new services! Quicker reaction to competitive moves -> Churn reduction! Individual products and tariffs -> Customer segmentation! Increased Revenue! Innovative offerings! Easy product bundling! Immediate customer interaction
13 Before we start our journey: Let s have a look at the environment

15 Tour Planning: Which route to take
16 Case Study: Complete Replacement of Billing Enviroment Parameters:! Mobile Network Operator with 4 million subscribers! Prepaid/Postpaid split: 80:20! Aggressive marketing strategy resulting in massive growth! Existing billing system can not cope with this growth
17 Initial situation
18 Step 1: New Prepaid System
19 Step 2: Parallel run of convergent system
20 Step 3: Complete replacement
21 Arrived: Where to go next
22 Multi Play Telecom Internet Service Provider TV
23 IMS Vision: From Multiple Vertical Silos...! MNOs rushed to deploy new IP/data services which resulted in vertical application platforms (silos)... Application Application Application Subscriber data Media functions Service delivery platform Service 1 Subscriber data Media functions Service delivery platform Service 2 Subscriber data Media functions Service delivery platform Service N IN Nodes PS domain CS domain OSS BSS Billing... which provide dedicated functions to realize only one specific service!
24 ... To a Re-usable Horizontal Service Delivery Platform... that provides a better way to deploy and integrate services. Service 1 Application Application Application Service 2 Service N Subscriber data Media functions IP Multimedia Subsystem IN Nodes PS domain CS domain OSS BSS Billing Key to success: standardized functionalities & standardized external interfaces.
25 IMS (IP Multimedia Subsystem) - Background! IMS is an open, 3GPP standardized and operator friendly NGN multi-media architecture which:! Provides centralized service control & delivery functionalities, in an additional infrastructure layer! Was originally designed for mobile networks... (3GPP Rel 5, March 2002)! Evolution Path to ALL-IP Seen as Fixed-Mobile Convergence & Service enabler (CS + PS: fills gap between traditional telecomm and internet)! Is an open BUT operator centric architecture (operators can open up BUT still control their networks)
26 IMS Provides Peer-To-Peer Sessions with Real-Time Capability! IMS enables direct IP connectivity between terminals (fixed & mobile) for services like real-time data, voice and video...! Source: 3G Americas Report Outlook on Convergence 2005:
27 IMS Maturity Index (accord. to STL Limited) The feet MACRO perspective - NO IMS in box
28 IMS Status : Vendors claim 50+ Trials
29 Traditional Billing Architecture: IN vs. IT SCP with integral balance & rating function IN Node (SCP) $$$ Balances Traditional IT & BCC environment OSS BSS CRM DWH Billing Rating Cust. DB Logic Mediation CS (voice) Mediation PS (data) IN world IT world (postpaid)
30 IMS sqeezing in OSS BSS CRM DWH IN Node (SCP) Rating $$$ Balances Cust. DB Logic IMS Charging Mediation CS (voice) Billing Mediation PS (data) IN world (prepaid) IMS /IP world (real IT world (postpaid)
31 IMS Online Charging Taking Center Stage Online / Real-time Charging System ( OCS for ALL prepaid services & all pre-/postpaid online functions ) OSS BSS CRM DWH IN Node (SCP) Logic IMS Charging Mediation CS (voice) Billing Mediation PS (data) IN world (prepaid) IMS /IP world (real IT world (postpaid)

33 AAA Entities in IMS Authentication Authorization Accounting! Core IMS (HSS)! User Identities public : similiar to MSISDN sip @mathias... tel private: similar to IMSI mathias@home.de New / harmonized! Policy & Charging Control (PCC) PCRF / PCEF - Rules Function - Enforcement F. (+ SPR, AF)! OCS : OCF (ECUR,SCUR), ABMF, RF! CCF, CDF, CGF = OFCS + Billing...have to work together automated / hand in hand to avoid leakage & service denial / frustration
34 What can you DO with Policy & Charging Control (PCC)! Analyse the IP data flow and apply differentiated charging keys for online & offline charging! Controls & enforces Authorized QoS! Credit management (OCS); enforces per-service-usage-limits! Block / allow IP traffic (gating); define wild-card services! Manage subscription policies! Aids correlation! Enables differentiated rates for roaming
35 COMMERCIAL (Pricing) Implications! Opportunity to charge for new/enhanced services & for certain IMS enhanced attributes (e.g. presence, QoS, grouping)! KISS principle (Keep It Smart & Simple)! Context/Content sensitive & more personalized :! Barred / Allowed / Free! Based on individual preferences & subscriptions! More hybrid online/offline = prepaid options for postpaid customers and vice versa... (cost control option, instant customer interaction)
36 TECHNICAL Implications / New Dimensions! DIAMETER protocol will dominate DIAMETER Accounting Requests & Answer (ACR & ACA) via Rf for Offline Charging Credit-Control-Request & and -Answer (CCR / CCA) via Ro for Online Charging! Billing on the basis of QoS / SLAs (QoS changes: precedence/priority, reliability, delay)! Correlation of IMS Services! IMS Charging Identifier (ICID)! Access network charging identifier! Inter Operator Identifier (IOI)! Application Charging Identifier (ACID)! Enhanced real-time & bi-directional transactions! Credit Pooling - Diameter Credit Control Appl. - see 3GPP TS ! According to Policies
37 Conclusion! Some gaps filled - more ahead! DIAMETER now! / 3GPP architecture where appropriate! Enhanced Charging & Billing as differentiator & stimulator! The biggest challenge is how little is needed...not how much [Martin Geddes] Intelligent trade-off (avoid correlation / apply KISS)! IMSMI - let IMS grow according to your needs! Real-time capabilities and OCS will be key
