Abstract: A method for authenticating a general or non-privileged application that is running on or is executed by a user equipment includes: in a first step, the user equipment performs or conducts an extensible authentication protocol (EAP) and/or an enhanced authentication and key agreement (AKA) with respect to, or towards, an entitlement configuration server entity, resulting in a privileged application or functionality receiving or comprising first token information; in a second step, the user equipment requests, from the entitlement configuration server entity, second token information, resulting in the second token information being received by the user equipment, the second token information being based on the first token information and provided to the general or non-privileged application; and in a third step, the general or non-privileged application uses the second token information to authenticate itself at, or towards, the resource server entity.

Abstract: A service discovery method for activating an embedded subscriber identity module (eSIM) device includes: initiating a device comprising an eSIM; and connecting the device to at least one of an entry point of a mobile network operator and a designated entitlement configuration server, using an entitlement configuration for automatically activating the eSIM via the connection to the entitlement configuration server and connecting the eSIM with a data service or a data network of the mobile network operator based on an entitlement of designated use-cases. The device and the entitlement configuration server validate parameters and/or methodologies for the entitlement configuration. The device requests the entitlement configuration server to provide supported parameters for a designated use-case and compares the response returned by the entitlement configuration server with its own supported parameters for the designated use-case.

Abstract: Stackable frac tanks for storing fluid which include a first tank and a second tank stackable atop of the first tank. A fluid connection device is affixed to the first and second tanks to fluidly connect the first and second tanks together. The stackable frac tanks may include a structural support frame interposed between the first and second tanks.
