METHOD AND APPARATUS FOR PRESERVING PACKET SWITCHED (PS) SIGNALING CONNECTION

Methods and apparatuses are provided for preserving a signaling connection using a UE in a wireless network. An RAU request message is sent from the UE, to at least one network node in the wireless network, when a suspension condition is detected at the UE while the UE is in a connected state. The UE receives a RAU response message from the at least one network node. Activation of a timer is restricted at the UE to preserve the signaling connection in response to receipt of the RAU response message, when at least one radio bearer associated with the UE is detected.
