Abstract
Disclosed is a method and access management entity for selecting a session management (SM) entity for serving a wireless communication device (WCD) in a core network that comprises an access management entity serving the WCD and an anchor SM entity that controls a first user plane entity that handles a data session associated with the WCD in a first domain, and a second SM entity for controlling a second user plane entity in a second domain of the core network. The method is performed by the access management entity and comprises selecting—based on WCD information and SM domain information—the second SM entity as an additional intermediate SM entity to control a user plane entity in the second domain for handling the data session in the second domain; requesting the second SM entity to act as the additional intermediate SM; and receiving a session response message.
