Patent number: 11297492Abstract: Techniques to protect subscriber identity in messages communicated between a user equipment (UE) and a cellular wireless network entity by using multiple ephemeral asymmetric keys are disclosed. The UE determines multiple ephemeral UE public and secret key pairs, while the cellular wireless network entity provides a network public key to the UE. The network public key may be updated over time. Multiple encryption keys based on the multiple ephemeral UE secret keys and the public network key are derived and used to encrypt a subscription permanent identifier (SUPI) to generate multiple subscription concealed identifiers (SUCIs). Each SUCI is used only once for messages communicated to a cellular wireless network and discarded after use. New SUCI are generated when the network public key is updated.Type: GrantFiled: March 27, 2018Date of Patent: April 5, 2022Assignee: Apple Inc.Inventors: Xiangying Yang, Lijia Zhang, Dawei Zhang, Huarui Liang, Shu Guo, Rohan C.

Publication number: 20210368421Abstract: A Public Land Mobile Network includes a network slice quota (NSQ) node to implement a quota on the number of user equipments (UEs) or (UE, PDU_Session) pairs that may be registered on a network slice. An access and mobility management function (AMF) queries the NSQ on whether quota is available for registration of a UE on a network slice in response to a notification of successful authorization and/or authentication (AAA) of the UE. Alternatively, the AMF may preemptively capture one or more units of network slice quota for the UE prior to initiation of the AAA procedure. The AMF may start a timer after UE deregistration is initiated, and not relinquish the quota unit held by the UE until after the timer's expiration. The network may also include a session management function (SMF) that provides UE identification as well as PDU Session ID when requesting registration of a UE.Type: ApplicationFiled: May 6, 2021Publication date: November 25, 2021Inventors: Vijay Venkataraman, Alosious Pradeep Prabhakar, Krisztian Kiss

Publication number: 20210368435Abstract: Methods and apparatuses are disclosed for requesting and providing service of a network slice deemed essential by a user equipment (UE). The UE transmits a request message to the network indicating that essential services are requested, and identifying the essential network slice. Based on the information in the request message, the serving network communicates with one or more network nodes to determine whether the requested services can be provided. This information is packaged in a response message and transmitted to the UE. If the current network is capable of servicing the requested network slice, then the UE remains with the current network. If not, then the UE initiates a search for an alternative network (PLMN or SNPN) capable of supporting the requested services. A successful search causes the UE to register with the newly-found network, whereas an unsuccessful search causes the UE to re-register with the current network.Type: ApplicationFiled: May 21, 2021Publication date: November 25, 2021Applicant: Apple Inc.Inventors: Nirlesh KOSHTA, Sridhar PRAKASAM, Karthik ANANTHARAMAN, Vijay VENKATARAMAN, Krisztian KISS, Nitin KUPPELUR, Deepak DASH, Pradeep PANGI, Kavya B.

Publication number: 20210368395Abstract: An approach to provide dynamic adjustment in order to meet the limitation of data rate per network slice in the uplink and downlink wireless connections in a wireless network. The approach uses a network slice quota (NSQ) management function, which keeps track of aggregated maximum bit rates (AMBR) for a slice. Upon reaching a limit, the NSQ functionality dynamically adjusts the user equipment (UE) data rates, reduces the quality of service (QoS), and/or rejects any protocol data unit (PDU) request. Several techniques are described that meet these objectives. In one technique, when the limit is reached, the session AMBR per subscription level is adjusted in proportionate ratio of the maximum bit rate per subscription level per UE. In another technique, when the limit is reached, there is a proportionate equivalent increment and decrement of session AMBR based on usage patterns of the subscription levels.Type: ApplicationFiled: May 10, 2021Publication date: November 25, 2021Applicant: Apple Inc.Inventors: Alosious Pradeep PRABHAKAR, Krisztian KISS, Rohit R.
