Abstract
Methods and systems for optimizing voice call setup times for user devices. A user device that is registered to a packet switched network and in an idle state receives a command to establish a voice call. The user device selects a legacy cell of a circuit switched network. The user device then establishes a radio connection with the selected legacy cell without first establishing a radio connection with a serving cell of the packet switched network.
