Abstract: A method, apparatus and computer program product are provided in accordance with example embodiments in order to provide methods, apparatuses, and/or systems that reduce and/or eliminate network inefficiencies caused by the persistence of user-equipment-specific associations with network interfaces and elements, including but not limited to user-equipment-specific associations on at least N2. In some example implementations, an AMF may assign a temporary ID containing particularized identification information to a UE in a manner that allows for selection by a (R)AN of a AMF and that enables an AMF to process an N1/N2 transaction, such as may occur when a UE enters an idle mode and/or transitions from an idle mode to a connected mode.

Abstract: There is provided a method, apparatus, and computer program for causing a first network apparatus to perform: signalling, to a second network apparatus, a request for an access token for a network function consumer for authorizing the network function service consumer to access a first service from a network function service producer; receiving an access token from the second network apparatus, wherein the received access token comprises an indication of at least one second access right unassociated with accessing the first service; and causing the received access token to be provided to the network function service producer when the network function service producer is signalled a request to provide a service to the network function service consumer.

Abstract: Various example embodiments described herein generally relate to apparatuses, methods and computer programs. For instance, an apparatus may include at least one processor and at least one memory including computer code, the at least one memory and the computer code configured, with the at least one processor, to cause the apparatus at least to receive, at a user plane function, a request to establish a session from a session management function, where the user plane function is part of a set of user plane functions. The at least one memory and the computer code may be further configured, with the at least one processor, to cause the apparatus at least to cause a response to be provided to the session management function, where the response includes information uniquely identifying the session in the set of user plane functions.
