An apparatus and method for efficient transitions between operating states
in a communication network, includes a preliminary step of having a
mobile station in a Dormant or Idle state. A next step includes requiring
a data transfer, either to or from the mobile station. A next step
includes transitioning the mobile station from the Dormant or Idle to an
Active state. A next step includes transferring a bearer path context for
the data from a Paging Control Function (PCF) to an RF Bearer Function.
This can include creating a tunnel using an Inter-PCF handoff procedure.
The result is a direct connection between an RF Bearer Function and an IP
Router, without the PCF being in the data path.
