Abstract: Methods and apparatus, including computer program products, are provided for supporting network functions. In some example embodiments, there may be provided a method that includes selecting, by a network node, a network function instance and/or a group of network function instances, the selecting based on information indicating membership of the network function instance in the group of network functions instances and the information including session information for a request associated with a session of a user equipment, the session information indicating whether the network function instance and/or the group of network function instances is assigned to the user equipment; and forwarding, by the network node, the request to the selected network function instance and/or the selected group. Related systems, methods, and articles of manufacture are also described.

Abstract: Techniques for securing an identifier of user equipment for a request external to a communication network are disclosed. For example, a method comprises receiving, at a network entity, a request for identification information for user equipment from an entity external to a communication network to which the network entity belongs. The network entity generates a secure identifier for the user equipment, wherein the secure identifier comprises an encrypted form of a public subscription identifier associated with the user equipment. The network entity sends the secure identifier to the external entity. The network entity receives the secure identifier in a subsequent request from the external entity. The network entity utilizes the received secure identifier to confirm the received secure identifier corresponds to the user equipment.

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: Systems, methods, apparatuses, and computer program products for dynamically updating routing identifiers (IDs) are provided. One method may include deciding, at a network node, to update a routing identifier for at least one user equipment. The method may then include obtaining or generating a new routing identifier to be assigned to the at least one user equipment along with authentication vectors, and transmitting the new routing identifier to an authentication entity.

Abstract: Methods, apparatuses and computer program products are provided to provide access control to a hosted virtual network in a communications system. An example method, apparatus and computer program product is configured to transmit a network identifier associated with a hosted virtual network to one or more allowed user equipment in a coverage area via a radio access network in the coverage area. The network identifier may include a Public Land Mobile Network identifier and a centrally or locally managed network identifier. The network identifier is configured to be stored on the one or more user equipment. The method, apparatus and computer program product is further configured to bar access to the hosted virtual network for one or more user equipment that are not allowed user equipment.

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: A method, apparatus and computer program product receive a traffic redundancy indication from a user equipment in a communication network or from a policy controller. The method, apparatus and computer program product determine whether traffic redundancy is needed for the radio access network and the user plane function based on the traffic redundancy indication. The method, apparatus and computer program product request the radio access network to not establish redundancy mechanisms in a circumstance where traffic redundancy is not needed for the radio access network. The method, apparatus and computer program product request the user plane function to not establish redundancy mechanisms in a circumstance where traffic redundancy is not needed for the user plane function.
