The operating principle of BlackBerry e-mail networks based on the fact that after the registration of the device in a network having coverage BlackBerry, system logs, and then detects every single BlackBerry device on an individual identification number (PIN). A unique number that is available in each unit, allows for PIN messaging (system «peer-to-peer»). These messages come from the device sending the device to the recipient instantly, and in addition, the system puts down a report on the delivery of such messages. In addition, the device automatically selects PIN-message header in red. BlackBerry Messenger app also uses the technology peer-to-peer, but the algorithm of the application resembles the algorithm of the well-known Internet messenger such as ICQ or AOL.
Intermediaries between the sender and the recipient are the center of the network operations RIM, where the servers are installed, and a mobile operator. It does not require manual synchronization of the smartphone and the e-mail server. In order to save Internet traffic and achieve "instant" transfer of data the company uses data compression algorithms.
