Method for connecting a host computer device to a wireless communication network, the host computer device being provided with an operating system with at least one pre-installed generic driver providing a generic communication protocol () for communication between the host computer device and a standard class of computer peripheral devices other than wireless modem devices, the method comprising the steps of: (a) connecting a wireless modem device to the host computer device; (b) setting up, by means of a pre-installed generic driver of the operating system on the computer device, a modem/host communication interface () for communication between the wireless modem device and the computer device; (c) connecting the host computer device to a wireless communication network via the wireless modem device; (d) routing data traffic (-) between the host computer device and the wireless communication network over the modem/host communication interface (). The generic communication protocol () is used in the modem/host communication interface () for transferring the data traffic (-) between the host computer device and the wireless modem device.

Wireless modem device usable on computer device without driver installation wherein computer has a proxy server application and pre-installed generic drivers

Method and device for managing simultaneous connections of a mobile telecommunications device to at least a wireless local area network and a mobile telephone network via a single terminal of the mobile telecommunications device, the method including the steps of: (a) establishing a first wireless connection of the terminal with the wireless local area network, (b) establishing a second wireless connection of the terminal with the mobile telephone network, (c) responding to each network at predetermined times, such that the first and second wireless connections are maintained, and (d) preventing simultaneous transmittals of data from the terminal to both networks over the first and second wireless connections.

Method and device for managing simultaneous connections of a mobile telecommunications device to different networks

A method for accessing a smart card from a host device, the smart card being connected to the host device via a telecommunications card, the telecommunications card having a command interpreter for interpreting host device commands and a modem with associated smart card reader for enabling the telecommunication and user identification the modem being only accessible to the host device via the command interpreter, the method including: (a) providing an access command on the host device, the access command instructing the command interpreter to pass on any attached command originating from the host device to the smart card reader; (b) attaching an application command to the access command and forwarding both to the command interpreter; (c) performing the application command on the smart card reader; (d) storing a response given by the smart card to the application command in a first buffer which is accessible towards the host device.

Method for accessing a smart card from a host device

A method for accessing a smart card (SIM) from a host device (TE) via a telecommunications card (MT), the telecommunications card (MT) comprising a command interpreter (TA) for interpreting host device commands and a modem (ME) with associated smart card reader, the modem (ME) being only accessible to the host device via the command interpreter (TA), the method comprising the steps of: (a) providing an access command (AT+CSIM) on the host device, instructing the command interpreter (TA) to pass on any attached command originating from the host device (TE) to the smart card reader; (b) attaching an application command (APDU) to the access command (AT+CSIM) and forwarding both to the command interpreter (TA); (c) performing the application command (APDU) on the smart card reader; (d) storing a response given by the smart card (SIM) in a first buffer which is accessible towards the host device (TE).
