Huawei announced the launch of ".. a UMTS Small Data Packet Storm solution.. When a smartphone user frequently refreshes pages on a site being browsed, the total amount of consumed traffic is very low. In scenarios where smartphone penetration is high, with many simultaneously connected users, air interface efficiency decreases greatly leading to decreases in capacity, user experience and total connected number of users. This is a "small data packet storm .. Huawei has developed solutions to combat "small data packet storms" in order to improve user experience for subscribers using smartphones".
Unfortunately, I can't find a technical description of this new solution.
"This solution has been deployed commercially in Canada, Europe, Hong Kong and other regions where it has helped operators achieve business success".
