A system for providing a wide range of telecommunications initiated data fulfillment services in which a multi-function code, such as “*#” (star, pound), input into an originating telecommunications device, such as a conventional land-line or wireless telephone, triggers the treatment of the input sequence as a multi-function code service request rather than a dialed directory number. The multi-function code is followed by an input data string to complete the multi-function code service request, which the user typically enters into the telecommunications device just like a conventional telephone call, except that the input string begins with the multi-function code. The telecommunications system recognizes the multi-function code as a trigger, and in response takes one or more actions, such as automatically terminating the call to an announcement and routing a data message to a data fulfillment center, which responds to the message by implementing a response action indicated by the multi-function code service request. For example, the data fulfillment center may respond by transmitting a message over a wireless data network or the Internet to implement a service, such as activation of a vending machine, remote control of device, delivery of a message over the Internet or wireless data network, initiation of an interactive Internet session with the originating device, or a wide range of other services. In addition, a charge for this service may be automatically charged to an account associated with the originating telecommunications device, which may be billed separately or incorporated on the user's conventional monthly telecommunications invoice.

Disclosed are techniques for performing an antivirus task in a mobile wireless device running an embedded operating system. In one embodiment, calls intended for an application programming interface (API) function code is redirected to an antivirus function code. The redirection to the antivirus function code may be performed by modifying a kernel structure to point to a modified entry list instead of an API entry list. The redirection to the antivirus function code may also be performed by modifying the API function code to allow the antivirus function code to execute before the API function code. The kernel structure or the API function code may be properly restored back to its original form. Software implementations of these techniques may be readily loaded and unloaded, and may not require re-installation of the embedded operating system.

The invention discloses a software upgrading method and a software upgrading device which are used for solving the problems that update of application software of a mobile terminal occupies large network flow and is complex and inconvenient. Function codes finishing concrete program functions in a main program are extracted and packaged to form an implementation class, a call interface is abstracted, and the main program calls the implementation class through the call interface so as to finish the concrete program functions. When the function codes need updating, the main program acquires an implementation class of a new version, and the implementation class of an old version is replaced with the implementation class of the new version. When the software is updated, users only need to download code files of part of logic from a server so as to replace original code logic, and because updated content is only a subset of overall program codes, the occupied network flow is small. Under a silent update mode, the software automatically finishes an upgrading process during the software using process of the users, and accordingly the aim of silent update is achieved.

The present invention is directed to facilitating communication within an automation system having a plurality of networks and network protocols. Specifically, a Modbus network is operably connected to a network. A fieldbus coupler operably connected to both networks having a program facilitates communication within the automation system wherein devices connected to the network can be accessed for monitoring and/or controlling via Modbus commands.

The FBC program using additional information contained in the Modbus function code and the message type reads or writes only the required information to and from the field devices. This specific read or write request of the information and the embedding of more than one message type reduces overhead and bandwidth usage, thus improving bus response time and efficiency.
