Abstract
A method and system for controlling when a radio link layer connection to a wireless terminal is released. A packet data serving node (PDSN) may determine what type of communication is being exchanged with a wireless terminal. For example, the PDSN may determine that the type of communication with the wireless terminal is a push-to-talk session, a file transfer protocol session, a web browsing session, or an instant messaging session. Based on the type of communication, the PDSN may signal a base station. In response to the signal, the base station may control when a radio link layer connection to the wireless terminal is released. The base station may set an active-to-dormant timer with a period of time indicative of when the radio link layer connection to the wireless terminal is released.
