Abstract: Consumer/enterprise and machine-to-machine functions in wireless devices have led to a need for end user consent, security of profile data while permitting remote profile management, and mixed profile types in a shared embedded Universal Integrated Circuit Card (eUICC). User consent is provided by the device or by the eUICC parsing an incoming profile management command and triggering a user prompt on a user interface. Security of profile data while permitting operation of remote profile management commands is obtained by authentication procedures. In some embodiments, control of command influence is also obtained by providing policy control functions at the profile level. Mixed profile types are supported by creating multiple security domains within the eUICC. Authentication is performed on a public key infrastructure (PKI) basis or on a pre-shared symmetric key basis.

Abstract: A downlink control information (DCI), such as a blanking DCI (bDCI) message may be transmitted by a base station (e.g., eNB) and received by a mobile device (e.g., UE). The bDCI may indicate that the eNB will not transmit a subsequent DCI to the UE for a duration of time. The UE may be in continuous reception mode or connected discontinuous reception (C-DRX) mode. The UE may therefore determine to enter a sleep state or take other action. The bDCI may specify an explicit blanking duration, or an index indicating a blanking duration from a lookup table, and/or the blanking duration (and/or a blanking duration offset value) may be determined in advance, e.g., semi-statically. When the UE is in C-DRX mode, the UE may be configured such that either the sleep/wake period of the C-DRX mode or the blanking period of the bDCI may take precedence over the other.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for utilizing a flexible slot indicator in wireless communication. A base station (BS) may establish communication with a first user equipment device (UE). The BS may determine a transmission direction for each of a plurality of symbols included in one or more slots. The BS may transmit a slot format indicator (SFI) to the UE. The SFI may indicate the transmission direction for each of the plurality of symbols included in one or more slots. The BS and the UE may perform communication during the one or more slots according to the determined transmission direction.

Abstract: Methods and apparatus for provisioning electronic Subscriber Identity Module (eSIM) data by a mobile device are disclosed. Processing circuitry of the mobile device transfers encrypted eSIM data to an embedded Universal Integrated Circuit Card (eUICC) of the mobile device as a series of data messages and receives corresponding response messages for each data message from the eUICC. The response messages from the eUICC are formatted with a tag field that indicates encryption and signature verification properties for the response message. Different values in the tag field indicate whether the response message is (i) encrypted and verifiably signed, (ii) verifiably signed only, or (iii) includes plain text information. Response messages without encryption are readable by the processing circuitry, and processing of the response messages, including forwarding to network elements, such as to a provisioning server are based at least in part on values in the tag field.

Abstract: The described embodiments set forth techniques for securely transferring a cellular wireless service subscription associated with an electronic subscriber identity module (eSIM) profile from a source wireless device to a target wireless device via communication with servers of a mobile network operator (MNO). An MNO provisioning server encrypts an activation code, used for transfer of the cellular wireless service subscription, with a session key generated based on a one-time-use eUICC public key and a one-time-use server private key. The encrypted activation code is protected from malicious third parties, as only the eUICC of the source wireless device can perform the decryption required by generating an identical session key to recover the activation code. The eUICC of the source wireless device deletes the eSIM profile from the eUICC before providing the activation code to the target wireless device to protect against eSIM profile cloning.

Abstract: A digital letter of approval (DLOA) is used by a subscription manager (SM) server to determine whether a device is compliant with requirements for an application to be provisioned. If the device is compliant, the application is provisioned to the device or to an embedded universal integrated circuit card (eUICC) included in the device. To increase the security of the device DLOA, the device DLOA is linked to the eUICC, in some embodiments. The linkage may be based on one or more platform label fields in the device DLOA. A database is consulted, in some embodiments, to confirm a relationship between the device and the eUICC identified in the device DLOA. In some embodiments, the eUICC signs the device DLOA and the device DLOA with eUICC signature is sent to the SM server. In some embodiments, the device provides a device signature on the DLOA independent of the eUICC.
