Publication number: 20240121588Abstract: 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).Type: ApplicationFiled: October 10, 2022Publication date: April 11, 2024Inventors: LU TIAN, Anders Askerup, David C. Williamson, John I. Ayers

Publication number: 20230363037Abstract: 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.Type: ApplicationFiled: May 9, 2022Publication date: November 9, 2023Inventors: Lu TIAN, Anders ASKERUP, David C.

Publication number: 20230189194Abstract: 5G provides for interworking with the 4G/LTE networks, which provides for mobility of user equipment between the 5G and 4G/LTE networks. Mobility from 5G to 4G/LTE requires deregistering user equipment from the 5G core network (5GC) by communicating a deregistration notification from the Evolved Packet Core (EPC) to the 5GC. Systems and methods disclosed herein provide for an optimized deregistration process through avoidance of redundant deregistration notification traffic injected into the 5G network by utilizing 4G/LTE connectivity information to determine whether or not to inject deregistration notifications into the 5G network.Type: ApplicationFiled: December 10, 2021Publication date: June 15, 2023Inventors: JOHN I. AYERS, LU TIAN, ANH TRAN, DAVID C. WILLIAMSON, MICHAEL R. KELLY

Publication number: 20230033997Abstract: Systems and methods are provided for automatic notifications of expired subscriptions. In various embodiments, a network function can request a subscription from a Unified Data Repository (UDR). The request for the subscription can include a request for a notification when the subscription expires or at a time prior to the expiration of the subscription. When the subscription expires or at the time prior to the expiration of the subscription, the UDR can provide a notification that the subscription has expired or is about to expire. Based on the notification, the network function can request to re-subscribe or request a new subscription from the UDR.Type: ApplicationFiled: September 27, 2021Publication date: February 2, 2023Inventors: ANDERS H. ASKERUP, DAVID C. WILLIAMSON, LU TIAN

Patent number: 10542413Abstract: In some examples, a computer-readable medium includes instructions. The instructions may be executable by a processing resource to maintain a default roaming restrictions database that stores default roaming restriction attributes specific to roaming classes of service defined by a network operator. The default roaming restriction attributes may be specific to the roaming classes of service independent of mobile country code and mobile network code. The instructions may also be executable by the processing resource to perform a lookup into the default roaming restrictions database to identify a particular default roaming restriction attribute specific to a particular roaming class of service defined by the network operator.Type: GrantFiled: April 18, 2016Date of Patent: January 21, 2020Assignee: Hewlett Packard Enterprise Development LPInventors: Tiffany A. Moore, John I. Ayers, Michelle Mitchell, Anders H. Askerup, David C. Williamson

Patent number: 6763340Abstract: A novel microelectromechanical system artificial neural network (MEMS ANN) device performs the function of a conventional artificial neural network node element. Micro-machined polysilicon or high aspect ratio composite beam micro-resonators replace as computational elements the silicon transistors and software simulations of prior-art ANNs. The basic MEMSANN device forms a non-linear (e.g., sigmoid) function of a sum of products. Products of the magnitudes of sine waves, applied to the input drive comb and shuttle magnitudes, are formed in the frequency domain and summed by coupling a plurality of resonators with a mechanical coupling frame, or by integrating them into one resonator. A sigmoid function is applied to the sum of products by shaping the overlap capacitance of the output comb fingers of the resonator. Methods of building and using various single MEMS ANN devices and multi-layered arrays of MEMS ANN circuits are also described.Type: GrantFiled: September 22, 2000Date of Patent: July 13, 2004Assignee: The United States of America as represented by the Secretary of the Air ForceInventors: Daniel J.
