SYSTEM, APPARATUS, AND METHOD FOR IMPROVING CIRCUIT SWITCHED FALLBACK CALL SETUP DELAY IN WIRELESS COMMUNICATION SYSTEMS

摘要

In accordance with aspects of the disclosure, a method, apparatus, and computer program product are provided for wireless communication. The method, apparatus, and computer program product may be configured to determine whether a device is switching from a first radio access technology to a second radio access technology to perform a circuit switched call setup process and determine whether at least one of a circuit switched domain registration procedure and a packet switched domain registration procedure is to be performed on the second radio access technology.
