Description / Abstract:
This document defines the Stage 2 service descriptions, call
flows and normative Stage 3 procedures that provide cdma2000 1x
circuit-switched Supplementary Services to the MS through the IMS
core network when the MS is camped on a Femtocell Access Point
(FAP).
Specifically, 1x Supplementary Services are provided to an MS
that is attached to a FAP using the cdma2000 1x radio interface.
The MS is homed in the 1x circuit-switched domain, and is
registered in the 1x HLR. The system takes advantage of IMS
functionality to provide subscribed services.
