  • Publication number: 20240154803
    Abstract: Techniques for authentication and key management for applications (AKMA) in a communication network are disclosed. For example, a method comprises receiving an indication from an application function that a first expiry time of a first application function key, generated using a first random value and configured to enable user equipment to participate in a session with the application function, has expired. The method generates a second application function key for the application function, using a second random value, with a second expiry time.

  • Publication number: 20240147244
    Abstract: A user equipment in a communication system, a unified subscription identifier data structure is constructed. The unified subscription identifier data structure includes a plurality of fields that specify information for a selected one of two or more subscription identifier types and selectable parameters associated with the selected subscription identifier type, and wherein the information in the unified subscription identifier data structure is useable by the user equipment to access one or more networks associated with the communication system based on an authentication scenario corresponding to the selected subscription identifier type. For example, during different authentication scenarios, the user equipment utilizes the unified subscription identifier data structure to provide the appropriate subscription identifier (e.g., SUPI, SUCI or IMSI) and associated parameters for a given authentication scenario.

  • Patent number: 11956627
    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.

  • Publication number: 20240086232
    Abstract: A method for managing memory for applications in a computing system includes receiving a selection of a preferred application. During user-controlled operation over the application, the transitions of selected application between foreground and background are monitored. A retention of the application in memory is triggered upon a transition of the application to background during the user operation. Retention of the application includes compressing memory portions of the application. Accordingly, the application is retained within the memory based on said compressed memory portions. A requirement to restore the retained application is sensed based on either a user selection or an automatically generated prediction and the application is restored from the retained state back to the foreground.

  • Publication number: 20230362637
    Abstract: Systems, methods, apparatuses, and computer program products for creation of a PCS connection between the remote user equipment (UE) and the relay UE. The remote UE may provide its identifier (e.g., a subscription concealed identifier (SUCI)) to the relay UE and the relay UE may forward this identifier to the network so that the network can authenticate the remote UE. The network may check the authorization of using the relay UE and/or for relaying the remote UE (e.g., both the remote UE and the relay UE may be checked for a configuration that permits the relaying). For the authentication and authorization, the access and mobility management function (AMF) associated with the relay UE may forward the messages between the remote UE and the authentication server function (AUSF) of the remote UE. In this way, certain embodiments described herein may address certain security issues related to relaying a remote UE.
