TIA TIA-1148

This document covers the Access Network aspects that are essential for the provisioning of IMS emergency services. In particular HRPD [2], [6], [7] is supported. For cdma20001-1X access networks the traditional circuit switch approach for emergency services [5] should be used.

All other IP based support for Emergency Services has been included in the Common IMS work with 3GPP. Requirements can be found in [4]. Stage 2 descriptions can be found in [3].
