Abstract: There is disclosed an apparatus. The apparatus comprises means for performing: initiating establishment of an N32-c transport layer security connection with an entity, the apparatus located in a first public land mobile network and the entity located in a second public land mobile network; sending from the apparatus to the entity on the N32-c transport layer security connection an N32-c handshake signalling message comprising domain name information of the apparatus to be used by the entity for establishing an N32-f transport layer security connection towards the apparatus; receiving a reply from the entity, the reply comprising domain name information of the entity to be used by the apparatus for establishing the N32-f transport layer security connection towards the entity; and using the domain name information received in the reply to establish the N32-f transport layer security connection towards the entity.

Abstract: Systems, methods, apparatuses, and computer program products for data storage (DS) function selection are provided. One method includes obtaining, from a network node, an address of a DS function that contains user equipment (UE) context information for at least one UE. The method may further include accessing, by a client, the DS function to register for the UE context information.

Abstract: Embodiments of the present disclosure relate to methods, apparatuses and computer readable storage media for hop-by-hop security. A proposed method comprises receiving, at a first apparatus and from a second apparatus associated with a first network function, a message directed from the first network function to a second network function, the message comprising a first signature and network function information, the network function information at least comprising identification information of the first network function; in accordance with a successful validation of the first signature, updating the message with a second signature specific to a service communication proxy implemented by the first apparatus; and transmitting the updated message to a third apparatus associated with the second network function, the updated message comprising at least the second signature and the network function information.

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.
