GERMANTOWN, Md. -- Megisto Systems, Inc., a leading developer of subscriber services switching software, today announced the expansion of its Mobile Services Delivery System (MSDS) to support charging and control for Push-to-Talk over Cellular (PoC). The latest addition to the MSDS Release 3.0 includes a SIP charging proxy that will deliver operators greater flexibility to charge consumers using PoC on a range of pricing models; including subscription plan, individual message, traffic volume, and time.

PoC revenues are expected to grow from $84 million in 2003 to $10 billion by 2008, with subscribers growing from 2.3 million to 340 million in this same timeframe, according to Emend Research. In a recent survey by IMS Research, mobile subscribers were highly divided with respect to their preferred method of payment. In this survey 36% of subscribers preferred "per message" charging, 37% preferred subscription-based charging, 17% preferred "per minute" or timed charging, and 9% preferred volume-based packet charging. Existing solutions limit the flexibility of the pricing models that can be offered by operators, especially in support of prepaid subscribers.

"As PoC is deployed in markets beyond the United States, support for real-time charging control will become increasingly important. Subscribers will no longer be on postpaid plans with large monthly commitments, so it will be necessary to support real-time authentication of PoC communications for prepaid subscribers," said Dr. Mehmet Unsoy, managing partner of MUnsoy Ltd. and former VP and Chief Architect of mmO2 in Europe. "It will also be necessary to support simple, easy to understand price plans for these users."

Megisto's MSDS R3.0 works in conjunction with operator Business Support System (BSS) infrastructure to deliver charging flexibility for both prepaid and postpaid subscribers. Specifically, the MSDS PoC architecture offers:

  • Broad charging flexibility - Delivery of flexible PoC charging options including the ability to charge based on subscription, volume, time, and number of messages

  • Pre-authentication of PoC sessions - Real-time pre-authentication of PoC sessions, allowing operators to immediately deliver PoC to both postpaid and prepaid subscribers without risk of revenue leakage

  • Single point of control and charging - A single integrated point of charging and control of PoC, enabling rapid deployment without requiring mobile core or BSS system upgrades



"Push-to-Talk over Cellular is an easy to use service that has already been proven to be a winner among both high-spending enterprise subscribers and cost-concerned consumers," said Carol Politi, vice president of marketing for Megisto Systems. "However, delivering the pricing flexibility desired by subscribers with existing solutions currently requires costly and complicated upgrades of mobile core infrastructure, as well as complex integration of both the PTT applications infrastructure and mobile core infrastructure with the operator's billing systems. The SIP charging proxy supported in the new MSDS R3.0 release supports delivery of pricing flexibility without such complexity, working seamlessly with existing systems."
