Patent number: 11979939Abstract: Emergency services support is indicated to roaming devices in a wireless network. A user equipment (UE) may receive a message from the wireless network indicating at least one public land mobile network (PLMN) that provides emergency services support for devices in limited service. The UE may store, in a non-volatile memory (NVM), an identifier of the at least one PLMN in a whitelist of limited service emergency services support. In response to a trigger in a roaming limited service condition of the UE, the UE may establish an emergency session with a selected PLMN based on the whitelist of limited service emergency services support.Type: GrantFiled: May 19, 2021Date of Patent: May 7, 2024Assignee: APPLE INC.Inventors: Vijay Venkataraman, Alosious Pradeep Prabhakar, Krisztian Kiss, Mohammed Sadique, Nirlesh Koshta, Rohit R.

Patent number: 11930442Abstract: Apparatuses, systems, and methods for reducing wireless device service interruptions. An indication of a disaster condition may be provided to a wireless device. The disaster condition may affect a home public land mobile network of the wireless device. The wireless device may perform cell selection in a manner influenced by the indication of the disaster condition. This may include considering cells associated with a forbidden public land mobile network for the cell selection, or excluding cells associated with the home public land mobile network of the wireless device that are unavailable, for example due to the disaster condition, among various possibilities.Type: GrantFiled: December 30, 2021Date of Patent: March 12, 2024Assignee: Apple Inc.Inventors: Sudeep Manithara Vamanan, Roland Gruber, Nirlesh Koshta, Anikethan Ramakrishna Vijaya Kumar, Sridhar Prakasam, Mona Agnel, Krisztian Kiss, Vijay Venkataraman, Haijing Hu, Robert Zaus

Publication number: 20240080790Abstract: This disclosure describes example embodiments and techniques to resolve UE behavior for several SAR use cases. The substate selection for a UE which has a valid SAR list and is currently camped on a cell which is in the registered PLMN or a PLMN from the list of equivalent PLMNs and whose TAI is not in the list of “allowed tracking areas” or is camped on a cell whose TAI is in the list of “non-allowed tracking areas,” has gaps in functionality and certain use cases. There are conflicting requirements as to what is the substate to be chosen by the UE. Additionally, there are certain behaviors missing for a UE in substate 5GMM-REGISTERED.NON-ALLOWED-SERVICE.Type: ApplicationFiled: September 3, 2021Publication date: March 7, 2024Inventors: Shashanka TOTADAMANE RAMAPPA, Anikethan Ramakrishna Vijaya KUMAR, Krisztian KISS, Nirlesh KOSHTA, Nitin KUPPELUR, Sridhar PRAKASAM, Vijay VENKATARAMAN

Patent number: 11882443Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first authentication request in response to a first triggering request from the UE to a mobility management node of a first Tracking Area (TA) in which the UE is located. In some embodiments, the UE may prepare and store an authentication response according to the first authentication request. In response to determining that the UE has moved from the first TA to a second TA, the UE may abort a sending of the authentication response, and may send the stored authentication response according to the first authentication request to the mobility management node of the second TA in response to the receipt of the second authentication request and in further response to a determination that a given parameter of each of the first and second authentication requests are the same.Type: GrantFiled: April 5, 2021Date of Patent: January 23, 2024Assignee: APPLE INC.Inventors: Nirlesh Koshta, Krisztian Kiss, Pradeep Pangi, Sridhar Prakasam, Vijay Venkataraman

Publication number: 20240015685Abstract: Systems and methods provide steering of roaming (SoR) information during a user equipment (UE) mobility registration process. In other systems and methods, instead of triggering mobility and periodic registration, a UE performs initial registration until a valid SoR is received in a visited country or network as long as a subscriber identification module (SIM) or a universal SIM (USIM) of the UE indicates that the UE is expected to receive SoR information due to initial registration in a visited public land mobile network (VPLMN).Type: ApplicationFiled: September 25, 2023Publication date: January 11, 2024Inventors: Nitin KUPPELUR, Krisztian KISS, Deepak DASH, Karthik ANANTHARAMAN, Kavya B.

Publication number: 20230397281Abstract: Systems and methods for managing synchronization of protocol data unit (PDU) sessions between a user equipment (UE) and a network are disclosed herein. In some embodiments, a determination of whether a message comprising a PDU session status information element (IE) should be sent is based on previous messaging between peer entities of the network. In some embodiments, a determination that the peer entity is informed of a relevant PDU session status is made after expected reply messaging is received in response to prior messaging. In some cases, a reply message without a PDU session status IE is sent from one entity to a peer entity when it is determined that each entity has a matching PDU session status. Cases involving failures detected at the network, and cases where an entity activates a data radio bearer (DRB) of a PDU session that is inactive at its peer are also discussed.Type: ApplicationFiled: September 3, 2021Publication date: December 7, 2023Inventors: Nirlesh Koshta, Anikethan Ramakrishna Vijaya Kumar, Basant Kumar, Krisztian Kiss, Pradeep Pangi, Sridhar Prakasam

Publication number: 20230388775Abstract: Apparatuses, systems, and methods for SoR list management and PLMN selection based on an SoR list. A UE may receive an SoR container which may include a list of OPLMNs. The UE may store a prior list of OPLMNs stored on a USIM of the UE on a memory of the UE. The UE replace the prior list of OPLMNs stored on the USIM with the list of OPLMNs included in the SoR container. The UE may consider the prior list of OPLMNs as a lower priority list as compared to the list of OPLMNs stored on the USIM. Additionally, in response to determining to move from a current PLMN, the UE may scan for a new PLMN based on the list of OPLMNs stored on the USIM.Type: ApplicationFiled: May 26, 2023Publication date: November 30, 2023Inventors: Sridhar Prakasam, Qi He, Rohit Matolia, Shashanka Totadamane Ramappa, Nirlesh Koshta, Xiangpeng Jing, Krisztian Kiss, Nitin Kuppelur, Kavya Ravikumar, Rajkumar Krishnaperumal, Pradeep Pangi, Karthik Anantharaman, Alosious Pradeep Prabhakar, Vijay Venkataraman, Lester Chan, Madhusudhan Cheripally

Patent number: 11812333Abstract: A device and method for a user equipment (UE) to implement power savings mechanisms when operating within a significant location. The UE identifies that the UE is at a significant location. The significant location is a location relative to a currently camped cell of a network. At a first time and at the significant location, the UE performs a type of operation related to the network connection. The UE stores information corresponding to the performance of the type of operation at the first time in a profile associated with the significant location. At a second time and at the significant location, the UE performs the type of operation related to the network connection. The performance of the type of operation at the second time is modified based on the information stored in the profile associated with the significant location.Type: GrantFiled: May 12, 2022Date of Patent: November 7, 2023Assignee: Apple Inc.Inventors: Srirang A.
