Abstract: There is provided a method for use by a mobile communication device for transmitting a location of the mobile communication device over a network using a protocol stack. In one embodiment, location data indicating the location of the mobile communication device is received. The location data can include, for example, Global Positioning System (“GPS”) coordinates. Thereafter a command for initiating transmission of the location data is received from a user. Then a delivery destination is received from the user. The delivery destination can be, for example, a telephone number of a cellular telephone. The location data is then provided to the protocol stack. A Short Message Service (“SMS”) message including said location data is then generated. The SMS message is then transmitted to the delivery destination.

Abstract: A mobile phone interface (MPI) is molded between the ends of a Universal Serial Bus (USB) cable. One end of the USB cable is plugged into a standard USB port on a personal computing device and the other end is plugged into a cellular telephone. The MPI comprises a USB serial interface engine (USB SIE), a digital translation block (DTB) and a cellular phone interface. The cellular phone interface provides electrical connections to the signals within the supported cellular telephone. The DTB performs synchronous and asynchronous data transfers and buffer functions in accordance with the implemented protocol. The USB serial interface engine performs serialization, de-serialization and USB set-up in accordance with USB standards. Software for controlling the MPI is installed on the computer system. The control software comprises a communication control stack, a hardware access driver and an external plug-in module.

Abstract: An apparatus and method for transferring high speed asynchronous data using a DMA controller. By using a conventional Universal Serial Asynchronous Receiver Transmitter (USART) with a small buffer, high speed asynchronous data can be manipulated by the DMA controller by use by other applications, such as wireless communication applications. The wireless communication applications includes Global System for Mobile communications (GSM), Code Division Multiple Access (CDMA), or Personal Digital Cellular (PDC). These wireless communication applications utilize high asynchronous data rates that would require more expensive USART with additional buffer capacity. In the receive mode, the high speed asynchronous data shifted into a DMA FIFO buffer from the USART. The data is then flushed into a host memory, such as a protocol stack by the DMA controller once the FIFO is full or if a timer expires. The data in the protocol stack is then manipulated by the wireless communication application.
