Drivers & Constraints Value based pricing Realtime Convergence Openness Perceived value vs cost of transport Operators must find the right balance between pricing sophistication and implementation constraints in a given competitive market The Media Co. The Telco Charge for Value Cover Costs e. g. - You can charge more for the latest track by Britney Spears rather than one that is 6 months old e. g. - Data traffic across the RAN and GPRS can be charged by the byte - You can charge more to watch a replay of a goal in the first 30 mins after it was scored - Storage can be charged by the byte Pros: Cons: - Increased profits - Matches with perceived value - Higher risk of not covering costs - More complex charging model © Logan Orviss International - Doc.

Drivers & Constraints Value based pricing Realtime Convergence Openness What is ‘realtime’ Operators must find the right balance between the advantages and hurdles of realtime “delayed” e. g. -calls and sessions are simply switched; no control is carried out - usage records are “pulled” on a regular basis (e. g. a few hours) and processed through traditional mediation, rating and invoicing processes and systems Pros: Cons: - Low cost - Handles large volumes - User experience is simplified (no/limited delays and dialogue) - Higher credit risk - Not a competitive differentiator “near real-time” e. g. -calls and sessions are allowed to proceed; limited control is possible -usage records are “pushed” and processed as quickly as protocols and systems would allow “real-time” e. g. - all calls and sessions are controlled through “signalling” messages -actions (advice of charge, recharge, barring, etc) can occur during the call/session Pros: - Satisfactory levels of Pros: credit risk - Return on Investment - Technically proven Cons: - Complex integration - dependent on equipment capabilities © Logan Orviss International - Doc.
