Abstract: Adaptive data collection practices in a multi-processor device. The device may include a first processor and a second processor. The first processor may operate in any of a plurality of power states. The first processor may indicate to the second processor when it transitions to a different power state. The second processor may collect information relating to its operation. The second processor may collect the information according to different information collecting modes depending on in which power state the first processor is operating. Less information may be collected in an information collecting mode corresponding to a lower power state of the first processor than in an information collecting mode corresponding to a higher power state of the first processor.

Abstract: Methods and apparatus for large scale distribution of electronic access control clients. In one aspect, a tiered security software protocol is disclosed. In one exemplary embodiment, a server electronic Universal Integrated Circuit Card (eUICC) and client eUICC software comprise a so-called “stack” of software layers. Each software layer is responsible for a set of hierarchical functions which are negotiated with its corresponding peer software layer. The tiered security software protocol is configured for large scale distribution of electronic Subscriber Identity Modules (eSIMs).

Abstract: A method and apparatus for a mobile wireless device configured to adaptively scan for a preferred wireless network while roaming is described. In one embodiment, at least a portion of a database including characteristic information regarding wireless networks can be stored within the mobile wireless device. Network characteristic information can include mobile country codes, mobile network codes, location area codes and cell-IDs. When the mobile wireless device is connected to a network that is not a preferred network, the mobile wireless device can use the database information in conjunction with characteristics from a connected wireless network to determine when to scan for the preferred wireless network.

Abstract: Embodiments are described for identifying and accessing an electronic subscriber identity module (eSIM) and associated content of the eSIM in a multiple eSIM configuration. An embedded Universal Integrated Circuit Card (eUICC) can include multiple eSIMs, where each eSIM can include its own file structures and applications. Some embodiments include a processor of a mobile device transmitting a special command to the eUICC, including an identification that uniquely identifies an eSIM in the eUICC. After selecting the eSIM, the processor can access file structures and applications of the selected eSIM. The processor can then use existing commands to access content in the selected eSIM. The special command can direct the eUICC to activate or deactivate content associated with the selected eSIM. Other embodiments include an eUICC platform operating system interacting with eSIMs associated with logical channels to facilitate identification and access to file structures and applications of the eSIMs.

Abstract: Methods and apparatus for activating a mobile device for use with a service provider. In one embodiment, a powered-off mobile device having an inserted Subscriber Identity Module (SIM) may be programmed with configuration data while “in box” (e.g., at a point of sale (POS), in a warehouse, etc.) using a near field communication (NFC) data interface. In another exemplary embodiment, information that is stored to a NFC accessible memory can be accessed when the device is non-functional e.g., to retrieve backup data.

Abstract: The invention provides a technique for managing write operations issued to a non-volatile memory included in a wireless device. A monitor software application executes on the wireless device and is configured to determine that a number of write operations issued to the non-volatile memory is greater than or equal to a write operation threshold associated with the non-volatile memory. In response, at least one application is isolated as the application responsible for issuing excessive write operations. The isolation can be carried out locally on the wireless device, or the isolation can be carried out remotely at a server by sending information about the write operations to the server. The monitor then limits additional write operations from being issued to the non-volatile memory so as to protect the non-volatile memory from becoming corrupted or inoperable.

Abstract: Apparatus and methods for managing and sharing data across multiple access control clients in devices. In one embodiment, the access control clients comprise electronic Subscriber Identity Modules (eSIMs) disposed on an embedded Universal Integrated Circuit Card (eUICC). Each eSIM contains its own data. An Advanced Subscriber Identity Toolkit application maintained within the eUICC facilitates managing and sharing multiple eSIMs' data for various purposes such as sharing phonebook contacts or facilitating automatic switch-over between the multiple eSIMs (such as based on user context).

Abstract: A mobile wireless device maintains a radio sector database. When receiving no response or a negative response from a radio sector to a transmitted signaling message, the mobile wireless device adds or updates the radio sector database. When receiving a positive response from the radio sector, the mobile wireless device deletes the radio sector from the radio sector database. Before transmitting signaling messages to a radio sector, the mobile device determines a time delay value if the radio sector is in the radio sector database. The mobile wireless device discards the signaling message when an elapsed time since a most recently transmitted signaling message to the radio sector does not exceed the determined time delay value. In an embodiment, each radio sector in the radio sector database includes a failure count value, and the determined time delay value depends on the failure count value.

Abstract: A method includes inter-chip data communications between a power-managed integrated circuit (IC) and a peer IC. The peer IC generates a data frame and prepends a discardable preamble of a predefined size to a payload of the data frame. The predefined size is a size not less than a size of data discarded by the power-managed IC upon the power-managed IC receiving a data frame while in a low-power state. The peer IC transmits the data frame to the power-managed IC. The power-managed IC, while in a low-power state, may receive the data frame from the peer IC and in response to receiving the data frame, begin exiting the low-power state. The power-managed IC, while exiting the low-power state, may discard a portion of the data frame such as for example, some or all of the discardable preamble, without discarding payload.

Abstract: In some implementations, a mobile device can analyze motion sensor data and proximity sensor data during a voice call to determine whether the mobile device is on a stationary object or worn on a user's body (e.g., in the lap or pocket of a user of the mobile device). The mobile device can adjust the transmit power level of the telephony transceiver during the voice call based on the determination.
