The present document describes the use of CS and IM

36、 services in combination, using the existing procedures that have been defined for CS and IMS. It includes the necessary function as adding an IM session to an ongoing CS call, adding a CS call to an ongoing IM session, supplementary services as they relate to CSICS and supporting capability exchang

37、e. The present document is applicable to UE and Application Servers providing for the combination of Circuit Switched calls and IM sessions. 2 References The following documents contain provisions that, through reference in this text, constitute provisions of the present document.
