DPI-triggered application-aware dormancy timer adjustment for mobile data bearers

摘要

Based on application information received from a Deep Packet Inspection (DPI) device, a Radio Network Controller (RNC) or similar device may select a dormancy timer value to optimize the use of network resources. In particular, the RNC may set an additional dormancy timer based on a default value or a rough determination of the application by examining port numbers. After the DPI device has received a sufficient number of packets to identify the underlying application, the DPI device may then propagate the application information to the RNC. Based on this application information, the RNC may determine the most efficient dormancy timer and modify the value of the default timer based on this determination.
