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: According to an example aspect of the present invention, there is provided a method, comprising: receiving a first message from a service-consuming second network entity in a second mobile network for a service-providing first network entity in a first mobile network, the first message comprising a first callback resource identifier, generating a second callback resource identifier on the basis of the first callback resource identifier, wherein the second callback resource identifier comprises a domain name of a security edge node in the first network, and transferring a callback message from the first network entity to the security edge node, the callback message comprising the second callback resource identifier.

Abstract: In an embodiment, there is provided a method for optimization of network signalling load and/or User Equipment power consumption in a packet mobile system wherein an User Equipment UE has access to a network comprising a Core Network CN accessed by a Radio Access Network RAN, a method wherein CN assistance information is provided by said CN to said RAN for an UE, said CN assistance information including information determined in said CN based on a learning by said CN of a traffic pattern and/or a mobility pattern of said UE, and said CN assistance information is used in said RAN to adjust RAN parameters enabling to control transitions between idle and connected state and/or power consumption in connected state for said UE.

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.
