Abstract:
A method of servicing asynchronous communication data calling call signalling in Code Division Multiple Access mobile communication network comprising the steps of:a step in which a subscriber attempts a call with modem dial command in case where the configuration of mobile station which the mobile subscriber has is a data terminal and a mobile terminal;a step in which said data terminal which recognized the modem dial command sends a call origination signal to the mobile terminal;a step in which said mobile terminal initiates a data call following the same call processing as that of a voice;a step in which said mobile terminal and a CDMA network concurrently initialize Radio Link Protocol when a traffic channel is allocated from a base station of the CDMA network to the said mobile terminal and a service option is responded;a step in which said mobile terminal informs the data terminal of the setup of the call by sending a connection confirmation signal to the data terminal after initialization and synchronization of said Radio Link Protocol;a step in which the Point-to-Point Protocols of the data terminal and a IWF of the CDMA network are self-initialized after the data terminal receives the modem connection confirmation signal;a step in which a Link Control Protocol is driven so as to initiate and synchronize a serial link after said Point-to-Point Protocols are self-initiated;a step in which Internet Protocol address and Transmission Control Protocol/Internet Protocol header compression of the data terminal and the IWF is negotiated by using Internet Protocol Control Protocol after initialization and synchronization of said serial link;a step in which the Transmission Control Protocol/Internet Protocol are driven after the Transmission Control Protocol/Internet Protocol are initiated and an address is allocated to the Internet Protocol;a step in which an application interface of the data terminal sends according to the Transmission Control Protocol/Internet Protocol modem initialization commands and the modem dial command for modem control to the IWF of the CDMA network;a step in which the data terminal receives a connect modem response message informing a call connection with the counterpart from the IWF of the CDMA network which received the modem initialization commands and the modem dial command for modem control; anda step in which the subscriber can be serviced with asynchronous communication data after the data terminal received the connect modem response message.
