Original Abstract Submitted
Aspects of the subject disclosure may include, for example, detecting initiation of a service associated with a UE, where the service comprises an OTT voice/video call, facilitating, for the service, activation of an end-to-end network slice between a core network and the UE, detecting a RAT switch determination for the UE, where the RAT switch determination relates to communicative coupling of the UE with a second network node, and where the second network node is associated with a second RAT different from the first RAT, responsive to the detecting the RAT switch determination, determining whether the service is ongoing over the end-to-end network slice, and, based on a determination that the service is ongoing over the end-to-end network slice, preventing the UE from communicatively coupling with the second network node until the service is determined to be completed or until the end-to-end network slice is released. Other embodiments are disclosed.
