The described embodiments set forth techniques for recovering one or more electronic subscriber identity modules (eSIMs) previously deleted from an embedded universal integrated circuit card (eUICC) of a mobile wireless device. Prior to deletion of an eSIM, the mobile wireless device uploads first eSIM subscription information to a cloud network services server and stores second eSIM subscription information in a secure memory of the eUICC. The mobile wireless device can subsequently download the first eSIM subscription information to verify matching to the second eSIM subscription information stored in the eUICC before displaying an option for recovering the eSIM. The mobile wireless device sends to a mobile network operator (MNO) provisioning server an eSIM recovery request notification that includes at least a portion of the first eSIM subscription information, and the MNO provisioning server provides an eSIM recovery response message indicating approval and a network address to download the eSIM.

Deleted eSIM recovery

Apparatuses, systems, and methods for performing efficient discovery of edge computing servers. A wireless device may provide an edge compute request to an edge discovery service, which may indicate one or more criteria for the edge compute request. The edge discovery service may select one or more edge application servers for the edge compute request based on edge compute resource availability profile information that it stores for multiple edge application servers and the one or more criteria for the edge compute request. The edge discovery service may provide a response to the edge compute request to the wireless device, which may include an indication of the selected edge application server or servers.

Efficient discovery of edge computing servers

The described embodiments set forth techniques for transferring an electronic subscriber identity module (eSIM) with the same integrated circuit card identifier (ICCID) value from a source mobile wireless device to a target mobile wireless device directly with a mobile network operator (MNO) provisioning server. The target mobile wireless device downloads the eSIM from the MNO provisioning server after deletion of the eSIM on the source mobile wireless device and reassignment of the eSIM with the same ICCID value to the target mobile wireless device.

Direct eSIM transfer between wireless devices

This Application sets forth techniques for binding and dynamic provisioning of international mobile equipment identifier (IMEI) values with cellular wireless service profiles, such as subscriber identity modules (SIMs) on physical SIM (pSIM) cards and electronic SIMs (eSIMs) on an embedded universal integrated circuit card (eUICC) of the mobile wireless device. When pSIMs and/or eSIMs change on the mobile wireless device, e.g., based on installation, activation, deactivation, de-installation, etc., IMEI binding logic accounts for the changes and maps IMEI values to pSIMs and/or eSIMs as required. IMEI values can be assigned based on a history of bindings between IMEI values and ICCID values of one or more eSIMS on an eUICC. A most recently used or a newly assigned IMEI value can be associated with an eSIM. Whether to assign an identical IMEI value to multiple eSIMs depends on requirements of associated cellular wireless service subscriptions.

IMEI binding and dynamic IMEI provisioning for wireless devices

A base station may operate in a context where the propagation delay between the base station and user equipment (UE) devices is large. The base station configures UE devices with a common delay. The base station receives a random access preamble from a UE device. The base station determines a time slot in which the random access preamble was transmitted, based on a configured correspondence between allowable time slots and subsets of an available set of preambles. The base station computes a Random Access Radio Network Temporary Identifier (RA-RNTI) based on parameter values including an index, of the determined time slot. The base station employs the computed RA-RNTI to address a random access response for the UE device.

Resolution of mismatch in calculation of random access radio network temporary identifier

Techniques described herein may enable a user equipment (UE) to optimize radio access technology (RAT) and radio resources (e.g., bandwidth parts (BWPs)) when communicating with the network. This may be based on one or more factors or conditions, such as whether the UE is currently using 4th generation (4G) RAT or 5th generation (5G) RAT, whether the UE is in an active mode or idle mode, a BWP used by the UE, whether an application or network service requires a certain throughput, a type of application being used by the UE, an amount of network congestion, and so on. RAT optimization may also be based on whether the UE is using a frequency range 1 (FR1) or frequency range 2 (FR2), whether the UE is stationary or moving, whether the UE is experiencing beam failures, uplink (UL) switches, link quality measurements (LQMs), reference signal received power (RSRP) measurements, and so on.

Systems, methods, and devices for optimizing radio access technology and resource selection

This Application describes mechanisms for enterprise remote management of cellular services provided via access credentials, e.g., subscriber identity modules (SIMs) and/or electronic SIMs (eSIMs), for wireless devices. To minimize requirements for user interaction, installation and management of business-supplied cellular service profiles on the wireless device can intercept alert notifications to reduce interruptions and allow for background management of the business-supplied cellular service profiles. Additionally, a business enterprise can use multiple, distinct services to initiate installation of an eSIM to a wireless device. When two different services attempt to install eSIMs on the wireless device in parallel, management software on the wireless device can control an order of installation and disallow duplicate installations of an identical eSIM to the wireless device. The management software can also monitor eSIM installations and manage alert notifications that occur during the eSIM installation process.

Enterprise remote management for cellular services

A user equipment (UE) device may perform random access to a base station in the context where propagation delay between the base station and the UE device is large. The UE device randomly selects a random access preamble from an available set of preambles. The UE device selects a time slot for transmission of the random access preamble based on a configured correspondence between allowable time slots and subsets of the available set. The UE device transmits the random access preamble to a base station in the selected time slot, with timing advance to compensate for a common delay. Thus, the base station, knowing the configured correspondence, is able to determine the time slot in which the random access preamble was transmitted. The UE device receives a random access response that has been addressed with a Random Access Radio Network Temporary Identifier (RA-RNTI).

Random access preamble transmission using a timing-based partition of preamble space

Methods, systems, and computer-readable mediums are configured to perform operations including detecting a plurality of synchronization signal blocks (SSBs) that are transmitted for a physical broadcast channel (PBCH), each of the SSBs having a SSB index comprising a set of bit values; detecting, from the plurality of SSBs, a first SSB received at a first time and a second SSB received at a second time that is different from the first time; decoding, for a first SSB of the plurality, first bit values of a first SSB index representing the first SSB and of a second SSB index representing the second SSB; determining, based on the first time and the second time, a receive time gap between the first SSB and the second SSB; and determining, based on the receive time gap and the first bit values of the first SSB index and the second SSB index, at least a second bit value of the first second SSB index representing the first SSB and the second SSB representing the second SSB.

Master information block decoding based on synchronization signal block timing

Apparatuses, systems, and methods for enhancement of network slicing for a UE. A UE may receive, from an AMF of a network, application related information associated with network slice data routing for data associated with an application. The information may be provided to the network by network slice customers. The UE may, in response to application initiation, determine traffic routing for data associated with the application. Traffic routing may be based on the application related information and a UE configuration associated with user privacy (e.g., user privacy setting) associated with the application. When the user UE configuration is enabled, the data may be routed via a default network slice and when the UE configuration is disabled, the data may be routed via a network slice indicated by the application related information. The UE configuration may be indicated by the application via a Boolean flag and/or via a user interface setting.

Network slicing enhancements

Apparatuses, systems, and methods for emergency communications (e.g., voice calls and/or SMS messages) for UE's without cellular coverage (e.g., in non-cellular coverage). A UE may establish, while out of range of cellular service, a peer-to-peer communication session with a relay UE using a channel in an unlicensed frequency band. The UE may transmit, using the peer-to-peer communication session, an emergency notification to the relay UE. The emergency notification may include an approximate location of the UE. Further the UE may communicate with a Public Safety Answering Point (PSAP), where the communications may be relayed between the UE and the PSAP by the relay UE. The approximate location of the UE may be based, at least in part, on a location of the relay UE and determining the approximate location of the UE may include performing a ranging procedure with the relay UE.

Emergency communication in non-cellular coverage

This disclosure relates to techniques for providing a framework for supporting custom signaling between a wireless device and a cellular network. A wireless device and a cellular base station may establish a wireless link. The wireless device and the cellular base station may perform custom signaling in accordance with the custom signaling framework.

Wireless devices, networks and methods may operate to have a wireless device cause a base station to trigger voice call continuity handovers responsive to the quality of the cellular radio link in addition to the base station triggering such handovers based on location or mobility. Furthermore, wireless communication devices may also perform monitoring of multiple buffers operating within the wireless communication device and associated with different respective communication layers, in addition to monitoring the quality of the cellular radio link, to perform intelligent dropping/discarding and/or scheduling of packets at the wireless communications device. Any one or more of these features may improve the ability of the wireless communications device to achieve stated Voice over Long Term Evolution (VoLTE) performance benchmarks in the context of the realities of current VoLTE networks.
