<p>In a UMTS wireless communication system a UE autonomously determines that it is going to transit from an active traffic mode into an idle traffic mode and informs the NodeBs in its active set that it is doing so. It does so either by using Layer 1 signaling, using the uplink DPCCH to send a message to the NodeBs indicating the transition, or by using Layer 2 signaling by via MAC PDUs that contain the message, which are delivered on the uplink E-DPDCH to the NodeBs.</p> |
