Abstract:
A data control system in a CDMA mobile communication system having a mobile telephone in which a serial input/output port connectable to a computer is provided, a base station for receiving/transmitting a radio wave applied from each mobile telephone of a mobile telephone subscriber, and a base station controller and mobile switching system for controlling said base station and for exchanging a voice signal by connecting the radio base stations to each other, said data control system comprising:a connection device to mobile data for receiving an asynchronous mobile data communication service request message by the mobile telephone subscriber from said base station controller and mobile switching system and if communication is made with a public network subscriber, for transmitting/receiving asynchronous mobile data to/from the mobile telephone subscriber along a mobile data path through said base station controller and mobile switching system;a connection device to public network data for receiving the asynchronous mobile data communication service request message by a public network subscriber from said base station controller and mobile switching system and if communication is made with the mobile telephone subscriber, for transmitting/receiving the asynchronous mobile data to/from the public network subscriber along a public network data path through said base station controller and mobile switching system;a data processing device for modem-processing the asynchronous mobile data from the mobile telephone subscriber by occupying an idle modem resource for asynchronous mobile data communication and by connecting a channel to the mobile telephone subscriber to thereby output the processed data as the public network data and for protocol-processing the asynchronous mobile data from the public network subscriber by assigning a modem resource of a modem port and by connecting one channel to the public network data to thereby output the processed data as the mobile data;a switching device for outputting the asynchronous mobile data outputted from said data processing device to said connection device to the public network data and for outputting the asynchronous mobile data from the public network subscriber to said connection device to the mobile data, while transmitting the asynchronous mobile data from said connection device to the mobile data and said connection device to the public network data to said data processing device; anda main processing device for assigning the idle modem resource for the asynchronous mobile data communication, if the asynchronous mobile data communication service request exists by the mobile telephone subscriber from said connection device to the mobile data and then for checking whether the idle modem resource is occupied by said data processing device and said connection state of the channel for the mobile data path, to thereby set the mobile data path between said data processing device and said connection device to the mobile data through said switching device and at the same time for checking the modem resource in which modem environment is constructed by using the channel for the mobile data path of said data processing device and the connection state of the one channel assigned to the public network data, to thereby set the public network data path between said data processing device and said connection device to the public network data through said switching device.
