This TS specifies service requirements for Combining CS and IMS services using a CS speech or CS multimedia call in association with an IMS session. The IMS session may consist of one or more IMS services. Requirements for the following capabilities are included:
  • Radio capability exchange.
  • Terminal capability exchange.
  • E.164 number exchange.
  • Adding IMS session to an ongoing CS call.
  • Adding a CS call to an ongoing IMS session.
  • Supplementary services as they relate to CSICS.
It is intended that the capabilities defined herein for CSICS shall support interoperability between different operator networks, and roaming.
