A mobile communications resource manager including a smart card configured to accept and store a user's personal information suitable for use in commercial transactions (physical tap or electronically) and communications operations, a cellular radio modem, at least one non-cellular radio modem and a controller. The controller is configured for establishing a short-range wireless connection via said non-cellular modem to at least one user accessible electronic device with human interface functionality and accepting a service request from the at least one user accessible electronic device and making a modem selection by selecting either a cellular or a non-cellular connection via a modem resident in the mobile communications resource manager to provide the communications link for the service request, based on a rule resident in the mobile communications resource manager.

Mobile communications resource management system

Disclosed is a structured model for developing DMA code and for performing DMA transactions. This model of structured DMA transactions provides a framework with default behaviors. Developers need only provide a minimal amount of configuration information and can then characterize subsequent DMA transactions in terms of a profile, thus reducing the amount of detailed and often redundant information that developers need to provide for each DMA transaction. In some embodiments, the DMA transaction model is expressed in terms of object-oriented programming constructs. In one example, a DMA enabler object captures general DMA operational parameters and manages underlying operating system objects and behavior. When device manager software receives an input/output request that involves a DMA data transfer, the device manager constructs a DMA transaction object that represents the DMA work request. During the processing of the DMA transaction, the DMA transaction object maintains state and status information.

Method and system for structured DMA transactions

The subject invention relates to systems and methods that automatically monitor and record component-related activities to support remote diagnostic capabilities. In one aspect, an automated computer diagnostic system is provided. The system includes a trace component that monitors computer-related activities between a driver and an operating system component. The trace component can be embedded within the driver or coupled thereto but, generally records activities relating to a given driver in contrast to generically for the entire operating system. A log records the computer-related activities to facilitate problem diagnosis with respect to the driver or the operating system component.

The subject invention relates to systems and methods that facilitate automatic version level updates of driver components in the context of an operating system framework. In one aspect, an automated computer versioning system is provided. The system includes a version library supplying various components of an operating system framework, wherein the version library defines revision levels and interfaces for the components of the operating system framework. A loader automatically distributes the interfaces in order to facilitate functional interactions with the operating system framework, whereby such distribution of the interfaces is based in part on a change in the revision levels.

Versioning support for drivers frameworks

Methods, systems, and computer program products that, by defining a common interface, allow for a single implementation of operations common to both kernel mode and user mode processing, relative to a hardware adapter. Corresponding kernel mode and user mode implementations of the operations are provided. For a given process, a call to the common interface is mapped to the kernel mode implementation for kernel mode processes and to the user mode implementation for user mode processes. The mapping may be performed at runtime or may be static. The common operation may provide a user mode process direct access to a hardware adapter, such as for sending and receiving information, without switching to kernel mode. A kernel mode implementation for operations unique to kernel mode processing, such as specifying security parameters for the hardware adapter to enforce, or initiating and terminating communication through the hardware adapter, also may be provided.

Process-mode independent driver model

The kernel is a shared environment. Accordingly, many different kernel-mode drivers utilize services provided by the kernel. Furthermore, when shimming of drivers is necessary, it is desirable to support shim reuse amongst drivers with similar problems or issues, rather than generating a customized shim for each driver. To facilitate kernel-mode shimming and shim reuse, context information needs to be retrieved and maintained so that shims can identify particular driver calls and preserve driver specific linkage information. The present invention accomplishes the forgoing by employing an intermediate structure, a content component, between a client or driver call and a common shared shim to provide the shim with contextual information.

Driver-specific context for kernel-mode shimming

A presently disclosed network oriented multiprocessing system, concentrated into a small space, uses a LAN (local area network) emulation protocol to transmit data packets directly between processing subsystems of the system via a bus connecting the processing subsystems. The processing subsystems and bus thereby constitute components of a virtual LAN defined by the LAN emulation protocol. The system also contains a storage subsystem which is connected to the same bus and is not a part of the virtual LAN. The spatial concentration of the system allows the bus to be operated at a speed sufficient to enable the processing subsystems to share access to the storage subsystem via the bus for retrieving stored information immediately relevant to program processes being executed in respective processing subsystems. Signal processes on said bus representing transfers relative to said virtual LAN are distinctly different from signal processes on the bus that are used to transfer information between said storage and processing subsystems. The virtual LAN defined by the LAN emulation protocol contains a virtual port for each processing subsystem currently active in the virtual LAN. This virtual port construct serves to maintain compatibility between software applications which define the LAN protocol and operating system software which supports both the LAN applications and other applications. The LAN emulation protocol permits each processing subsystem to independently initiate a failure communication to the other processing subsystems as well as to independently remove itself from and re-insert itself into the virtual LAN. It also permits any processing subsystem to conduct a &ldquo;broadcast&rdquo; data packet transfer to all other processing subsystems.
