Abstract: Examples described herein generally relate to a scalable multi-tier storage system. An entry may be added and/or deleted within the storage system. To delete an entry, the storage system may determine whether the entry corresponds to the file or the directory based on directory metadata, and request deletion of the directory metadata associated with the entry from the directory volume based on determining that the entry corresponds to the directory, and further requesting deletion of the file from a file volume based on a determination that the entry corresponds to the file. To add a file, the storage system may generate directory metadata associated with the entry in the directory volume based on a determination that the entry corresponds to the directory, and may further allocate file metadata in the file volume based on a determination that the entry corresponds to the file.

Abstract: Techniques for provisioning electronic devices that may not have a local provisioning agent (LPA), such as Internet of Things (IoT) devices, to a mobile network of a mobile network operator (MNO), are discussed herein. The IoT devices and/or the associated embedded subscriber identity module (eSIM) may have one or more device profile templates stored thereon, where individual ones of the device profile templates are associated with a particular MNO. A device provisioning system of an MNO may provision the IoT device in a machine-to-machine (M2M) manner over the air (OTA) by communicating, such as via a radio node, one or more configuration parameters to the IoT device. The IoT device may identify a device profile template associated with the MNO to which the IoT device is to be provisioned and configure that device profile template based at least in part on the configuration parameters received from the device provisioning system.

Abstract: The methods, systems, and computer readable media discussed herein are directed to enabling a fifth generation cellular-wireless access technology (5G) user equipment (UE) to receive 5G service using a fourth generation cellular-wireless access technology (4G) subscriber identity module (SIM). Upon powering on, the 5G UE may determine whether a mobile network operator (MNO) public key file exists in the 4G SIM. Upon determining that the MNO public key file exists in the 4G SIM, the 5G UE may retrieve a MNO public key value from the MNO public key file, read a subscription permanent identifier (SUPI) from the 4G SIM, generate a subscription concealed identifier (SUCI) based on the SUPI and the MNO public key value, send the SUCI to a 5G mobile network for registering the 5G UE, and begin receiving 5G services from the 5G mobile network.

Abstract: Examples described herein generally relate to maintaining a snapshot of a multitier distributed file system. A snapshot directory volume of a directory volume can be created at least in part by copying, to the snapshot directory volume, metadata of the directory volume. Based on a file access request, it can be determined whether the file has not been snapshotted. If not, a snapshot file record of the file, and associated with the snapshot directory volume.

Abstract: A 5G user equipment (UE) can register for 5G services with a telecommunication network in part using a Subscription Concealed Identifier (SUCI), an encrypted version of a subscriber identifier, so that the actual subscriber identifier is not exposed during network registration. Legacy SIMs originally deployed for 4G/LTE and other legacy wireless access technologies store an international mobile subscriber identity (IMSI), but do not store a network public key needed to generate a SUCI. However, a 5G UE can still use a legacy SIM to securely obtain 5G services by encrypting the IMSI from the legacy SIM using a network public key stored in the 5G UE's own memory to generate a SUCI, and then transmitting the generated SUCI to the telecommunication network during network registration. Accordingly, the IMSI on the legacy SIM is not exposed during network registration.

Abstract: Systems and methods discussed herein are directed to subscriber identity (SIM) cards that include multiple profiles. The SIM cards include logic, e.g., an application or an applet, configured to change profiles so that the correct profile is selected for use with the electronic device that includes such a SIM card within the appropriate wireless communication network. The ability to change profiles may be based on activity of the electronic device, e.g., events, within the wireless communication network.

Abstract: Telecommunication services are received at a user device using an embedded subscriber identity module (eSIM) profile stored on the user device while the user device is located in a first geographical area. A list of preferred remote SIM provisioning (RSP) platforms that provide eSIM profiles specific to a partner MNO of the MNO in a second geographical area is also received from an eSIM management platform of an MNO; The user device is then determined to have moved to a second geographical area based on a geolocation of the user device. Subsequently, an additional eSIM profile specific to the partner MNO of the MNO is downloaded to the user device from an RSP platform of one or more RSP platforms included in the list of preferred RSP platforms.

Abstract: A multiple-output load driving device includes a plurality of output terminals (OUT1 to OUT4) for outputting an output current to each of a plurality of loads (Z1 to Z4), a control portion (8) configured to select either a non-DC current mode in which a non-DC current is used as the output current or a DC current mode in which a DC current is used as the output current, and a first terminal (MSET2). In a case where a low-level signal is supplied to the first terminal, in the non-DC current mode, the non-DC current is outputted from all of the plurality of output terminals. In a case where a high-level signal is supplied to the first terminal, in the non-DC current mode, the DC current is outputted from a predetermined one (OUT4) of the output terminals, while the non-DC current is outputted from the other output terminals (OUT1 to OUT3).

Abstract: An eSIM management platform may receive service feature information on multiple remote SIM provisioning (RSP) platforms that are designated by a mobile network operator (MNO) to distribute embedded subscriber identity module (eSIM) profiles for a partner MNO of the MNO. The eSIM management platform may evaluate multiple RSP platforms based on one or more service features of each RSP platform to select one or more RSP platforms of the multiple RSP platforms for population into a list of preferred RSP platforms for the geographical area. The eSIM management profile may send the list of preferred RSP platforms to a user device to configure the user device to use an eSIM profile provided by an RSP platform of the one or more RSP platforms. The user device may use the eSIM profile to obtain telecommunication services from the partner MNO while the user device is in a geographical area.

Abstract: A user device may receive a list of remote SIM provisioning (RSP) platforms that are designated by a mobile network operator (MNO) to distribute eSIM profiles of a partner MNO of the MNO, in which the partner MNO provides telecommunication services in a geographical area. The user device may obtain one or more service features of individual RSP platforms in the list of RSP platforms from a meta RSP interface (MRI) platform when the user device is in the geographical area. Subsequently, the user device may determine a number of service parameters that are met by the one or more service features of the individual RSP platforms. In response to identifying a single RSP platform as meeting a highest number of service parameters, the user device may request a download of an eSIM profile from the single RSP platform to access the telecommunication services of the partner MNO.

Abstract: Systems and methods discussed herein are directed to handling the identity and authentication of server security certificates on SIMs, and establishing secure channels with cloud servers via a wireless communication network using the security certificates and Public Key Infrastructure (PM) libraries on SIMs. A mechanism to manage the security certificates on SIMs using an Over-the-Air (OTA) platform of the wireless communication network and certificate authority network elements is provided. Multiple cloud systems and their cloud servers are supported by storing multiple cloud certificates on SIMs and enabling features of a dynamic selection of the appropriate server certificate by the OTA platform for secure communication. Accordingly, electronic devices may be used within the wireless communication network for exchanging data with multiple cloud servers without changing codes/software devices, SIMs, etc.

Abstract: Some storage systems are configured with VDL (valid data length) type controls that are implemented on a per cluster basis and, in some instances, on a sub-cluster basis, rather than simply a per file basis. In some instances, per-cluster VDL metadata for the storage clusters is stored and referenced at the edge data volume nodes of a distributed network for the storage system rather than, and/or without, storing or synchronizing the per-cluster VDL metadata at a master node that manages the corresponding storage clusters for the different data volume nodes. Sequence controls are also provided and managed by the master node and synchronized with the edge data volume nodes to further control access to data contained in the storage clusters.

Abstract: Intelligent network access technology (NAT) control is described herein. An event associated with a mobile computing device can be detected. Responsive to the event being detected, a subscriber identity module (SIM) associated with the mobile computing device can access location information associated with a location of the mobile computing device. The SIM can access a configuration table storing NAT data provided by a network for controlling which NATs the mobile computing device is permitted to use to access the network. The SIM can determine, based at least in part on the NAT data and the location information, that a requested NAT of the mobile computing device is not a permissible NAT for the mobile computing device in the location and the SIM can cause the mobile computing device to connect to the network via an alternate NAT.

Abstract: Examples described herein generally relate to maintaining a snapshot of a multitier distributed file system. A snapshot directory volume of a directory volume can be created at least in part by copying, to the snapshot directory volume, metadata of the directory volume. Based on a file access request, it can be determined whether the file has not been snapshotted. If not, a snapshot file record of the file, and associated with the snapshot directory volume.

Abstract: A request from a mobile operator network (MNO) is received at a Subscription Manager Secure Routing (SM-SR) associated with the MNO. The request is for deleting an embedded Subscriber Identity Module (eSIM) profile from an embedded Universal Integrated Circuit Card (eUICC) of a machine-to-machine (M2M) device. The eSIM profile is provided by a Subscription Manager Data Preparation (SM-DP) of a third-party partner of the MNO. A command is sent from the SM-SR to an application on the M2M device to delete the eSIM profile from the eUICC of the M2M device. An indication is then received from the application by the SM-SR indicating that the eSIM profile has been deleted. Accordingly, the SM-SR associated with the MNO may send a notification to the SM-DP of the third-party partner indicating that the eSIM profile has been deleted from the eUICC of the M2M device.
