This study aims to provide use cases and requirements for the following aspects of interworking between 3GPP networks and Enterprise voice services:
  • Support for CS and IMS voice services interworking with IP-PBX services while at the same time maintaining full operator visibility and control of the related voice service signalling in the mobile operator's core network,
  • Mobile operator control of security, manageability and operation of IP-PBX interworking function,
  • Mobile operator control of availability of IP-PBX services to 3GPP mobile devices,
  • Mobility between cellular and Enterprise environments, and
  • Continuity when an IMS session is moved between cellular and Enterprise environments and when the IMS session is moved between mobile and fixed devices in the Enterprise environment.
Use cases and requirements from other SDOs will be considered in this study.

The following services aspects will be covered:
  • CS and IMS services,
  • Enterprise specific value-added services (e.g. "short code dialling", conferencing, transfer of sessions to a softphone on a PC), and
  • Interaction between services provided by the mobile operator and services provided by the Enterprise.
