The Wall Street Journal brings a news report from Helsinki, that Comptel announced the use of its mediation software by tier 1 mobile operator in the USA. In this news report it is said that the mobile operator required a high performing solution capable of handling real-time data collection and complex event processing (CEP) with ease. Looking at the website of Comptel for more details, I found that Comptel says it has comprehensive and complex event processing, however no more details were available about the solution. I have written before about event processing and the mobile world, and believe that we'll see a lot more of it. It is interesting to view how this one was implemented.
