Abstract: The systems and method disclosed herein optimize the deregistration of user equipment (UE) from the 5GC. For example, when the UE operates in single-registration mode, for AMF 3GPP access registration with drFlag attribute set to false (or to be absent) in UDM/UDR, a “new attribute”, singleRegIndication, is defined. The AMF sets the singleRegIndication value to “NO_INDICATION” when there is no N26 interface connection to MME. UDM will not instruct HSS to cancel MME (and SGSN/VLR) if there is an old AMF 3GPP registration for which “NO_INDICATION” or “DEREGISTER_SN” is set as the singleRegIndication value (i.e. the old AMF was already registered with the single registration). Otherwise, the AMF sets the singleRegIndication value to “DEREGISTER_SN” when the AMF has established a N26 interface connection to the old MME. UDM can instruct HSS to cancel the MME (and SGSN/VLR).

Abstract: Examples described herein relate to techniques for session continuity when a User Equipment (UE) is moving to a destination core of a destination communication system in an interworking network architecture. Example techniques may include registering by a destination subscription manager in a Network Repository Function (NRF) a subscription profile and indicating support for a session continuity for the User Equipment (UE). Discovering the subscription profile by a source subscription manager by utilizing the NRF. Receiving the session information by the destination subscription manager from the source subscription manager based on the discovery of the subscription profile. Enabling continuity of the session by the destination subscription based on the received session information.

Abstract: Techniques for storing data used in making announcements in telephone communications are disclosed. In an embodiment, an announcement depends on classes of services associated with telephone subscribers. The classes of services represent call types or call features such as call-forwarding unconditional, call-forwarding busy, call-forwarding no answer, etc. A first database associates subscribed phone numbers with a class of service. A second database defines the class of services such as the call types, the telephone digit pattern in the subscribed telephone numbers, the condition for an announcement, etc. A third database defines a default class of service for use in case a phone number is not associated with a class of service in the first database.

Abstract: Systems, methodologies, media, and other embodiments associated with provisioning an internet protocol (IP) multimedia sub-system (IMS) are described. One exemplary system embodiment includes logic for provisioning an IMS initial filter criteria (IFC) database with IFC data and logic for provisioning an IMS user database with user data. The exemplary system embodiment may also include logic for provisioning an IMS call session control function (CSCF) logic with data that relates user data to IFC data based, at least in part, on a class of service (COS) identifier.

Abstract: Systems, methodologies, media, and other embodiments associated with provisioning an internet protocol (IP) multimedia core network subsystem (IMS) are described. One exemplary system embodiment includes logic for provisioning an IMS application server (AS) database with AS data and logic for provisioning an IMS user database with user data. The exemplary system embodiment may also include logic for provisioning an IMS initial filter criteria (IFC) database with data that relates a user to an AS based, at least in part, on an AS class of service (COS) identifier.

Abstract: Systems, methodologies, media, and other embodiments associated with provisioning an internet protocol (IP) multimedia core network subsystem (IMS) are described. One exemplary system embodiment includes logic for provisioning an IMS charging database with charging data and logic for provisioning an IMS user database with user data. The exemplary system embodiment may also include logic for provisioning an IMS call session control function (CSCF) logic with data that relates a user to charging information based, at least in part, on a charging class of service (COS) identifier.

Abstract: A method and corresponding apparatus and system of controlling access to communication services by a roaming wireless device are described. The method includes receiving a request for roaming wireless device service information related to a roaming user and determining which services the user has access to for the requesting system, if the user is determined to have access to the requesting system. The method also includes transmitting user service information concerning the services to which the user has access. The apparatus includes a memory, a communication system, and a processor. The memory stores: (1) user information including a class of service (COS) identifier and (2) COS restriction information. The processing system, coupled with the communication system and the memory, generates a reply message based on comparing information in a service request message received by the communication system with the stored information in the memory.

Abstract: A method for authenticating a mobile communication device (MCD) to a wireless network. The method includes transmitting from the wireless network to the MCD a first value. The method further includes receiving from the MCD at the wireless network a second value, the second value representing a function of the first value, a shared data value that is stored in both the MCD and the wireless network, and at least one metric pertaining to an application program stored in the MCD.
