Abstract
A radio access network (RNC) assigns for a real-time media session a real-time access bearer that can be shifted between a dedicated channel state and a common channel state. The assignment is made in response to receiving an access bearer assignment message indicating that the real-time media session requires a real-time access bearer of that type. The media activity of the real-time access bearer is then monitored, and the access bearer shifts to the common channel state upon detecting media inactivity during the dedicated channel state, and shifts to the dedicated channel state upon detecting media activity during the common channel state.
