Abstract
Circuit-switched fallback (CSFB) is a technique to deliver voice-services to a mobile, when the mobile is camped in a long-term evolution (LTE) network. Certain aspects of the present disclosure provide techniques that may help reduce delays in call setup related to CSFB and, in some cases, avoid unnecessary paging.
