Yes it is true that the internet and mobile network will be merged in coming years, and therefore the mobile network operators will find some difficult time to adjust the internet protocols to their core network but I don't believe that the core network protocols or applications will be decided by solely cisco or any such companies, it is because,there are engineers in IEEE who makes the standards based on the current situation of mobile network, they will certainly take the advice from mobile network operators as this is the best way to get best solution.
