A method implemented by a network node is disclosed. The method includes: obtaining registration state information associated with a user equipment (UE) from a first core network node, the registration state information indicating at least one of fourth-generation (4G) UE single radio voice call continuity (SRVCC) capability or fifth-generation (5G) UE SRVCC capability for the UE, wherein the UE is registered with a first IMS network that includes the network node using a session initiation protocol (SIP) via an access network supported by a second core network; and providing, to a second IMS network node, an indication of a single UE SRVCC capability for the UE.
