    摘要： A Radio Interface Layer (RIL) is disclosed. The RIL comprises an API set which provides a level of abstraction between the radio on a cell phone and the software of the cell phone. The API set of RIL is roughly based on the GSM AT interface as defined in GSM specifications 07.05 and 07.07. The API set provides access to functionality contained within a cellular telephone, such as a GSM or CDMA compatible telephone. These APIs allow applications running on an operating system in the cellular telephone to issue commands without knowledge of the underlying radio structure of the cellular telephone and specific knowledge of the GSM-type commands. For example, these APIs allow the applications to access to phonebook entries, restrict access to data and functionality using passwords, access file and message storage, and perform many other functions. The RIL is divided into a hardware-independent proxy layer, called by various software components, and a driver layer that is hardware-specific.

    摘要： A cellular telephone clock is automatically set to correlate to a timestamp contained in a Short Messaging Service (SMS) status report. Accordingly, an exemplary cell phone clock can be properly set any time the cell phone receives a status report. By setting the cell phone device time to correlate to the world time, the exemplary cell phone clock can be automatically set, without requiring any action by the user and without requiring a special time set control message. When the cell phone transmits an SMS message, the cell phone stores the device time corresponding to the time that the message was sent (DTS). When a status report is received, the exemplary cell phone stores the device time corresponding to the time that the status report was received (DTR). Additionally, the cell phone stores the world time that is included in the status report by the SMSC that handled the message (WT). By subtracting the DTR from the WT, the cell phone can determine an approximate difference between the cell phone's device time (and clock) and the world time. By adding this difference to the current device time (DTC), the DTC can be set to closely approximate the WT.

    摘要： The present invention provides for a virtual serial port (VSP) situated between a serial port in a mobile electronic device, applications that require a serial port connection handle, and other applications that require command-mode access to the serial port. Data-communication applications (e.g. web browsing, e-mail, etc.) connect to the serial port through the VSP. The VSP creates a virtual connection handle that is returned to the application. Command-mode requests (e.g., short messaging requests) are received by the hardware abstraction layer, translated into command-mode messages (e.g., AT commands) and placed in a queue. The VSP multiplexes the serial port between the currently-open data communication session (data-mode) and command-mode messages by periodically suspending the currently-open connection and processing one or more command-mode messages that are in the queue. A buffer continually stores incoming data while the data communication session is suspended. The VSP uses a heuristic calculation to determine the maximum time interval for which the data-communication session can be interrupted. The heuristic calculation takes a percentage of a time-quantum (e.g. 0.5 seconds) based upon the ratio of an average bit rate for air communication (e.g. 7000 bits/sec) and a bit rate for the serial port (e.g. 152,000 bits/sec). This ensures that data-communications are not interrupted for a time interval long enough to result in lost data-packets. The parameter for the time quantum and other parameters may be statically or dynamically adjusted to account for a finite buffer size in the hardware.

    摘要： Described is a system and method by which a collection of software packages for installing (e.g., on an embedded computing device) are reviewed for their dependent relations, whereby it is possible to choose a maximal set of install possibilities to allow for maximal version updates for any given package in the fewest update steps possible, while honoring package dependency constraints. An update validation process organizes and validates update packages that have been downloaded to a device, and builds a graph for each group. The graph data including paths between updates are processed to validate the updates and to determine a minimal and optimal set of packages that can be applied to the existing image on the device to produce the desired update, with the least amount of weight (cost) when more than one path can be used to get to the same version.

    摘要： A system and method is disclosed for synchronizing certain periodic activities and/or processes in a computer system or device. The synchronization allows more efficient use of the computer system's or device's processing capabilities, and may result in conservation of electrical power. In one example embodiment, a periodic scheduler is implemented to periodically verify the continued existence of critical processes operating in the computer system or device. Corrective, or other appropriate, action may be taken in the event of a failure of a critical process. A schedule list, which may be a linked list, may be used to track the periodic processes that are to occur. Upon registration of a critical process, the schedule list may be modified to synchronize the new periodic process with the existing schedule list.
