Abstract
Techniques and mechanisms for use in facilitating home network assisted concurrent access to network slices in multiple visited public land mobile networks (VPLMNs) are described. A control plane (CP) function for mobility management may receive, from a UE (e.g., configured without dual connectivity), a message which indicates a registration request for registration using a first network slice and a second network slice. The CP function may manage registration for the UE in response to the registration request. The CP function may receive, from the UE, a message which indicates a request for establishing a protocol data unit (PDU) session using the second network slice which is not supported or available in the first VPLMN. The CP function may forward the request for establishing the PDU session to an application function (AF) for managing establishment of the PDU session for the UE using the second network slice in a second VPLMN.
