Abstract
Methods, systems, and devices are described for call setup (e.g., VoLTE) for a wireless communication device. During a call setup procedure, the device may implement a 'keep alive' mechanism to maintain an RRC connection established as part of the call setup procedure. The 'keep alive' mechanism may be configured to insert some padding traffic (e.g., dummy packets) to maintain the RRC connection, for example, by restarting the network RRC connection release timer to prevent its expiration and release of the RRC connection during call setup.
