【発明の名称】ワイヤレスデータ通信ネットワークと共に用いるためのコンピュータシステム
Document Type and Number:
Japanese Patent JPH09500251
Kind Code:
A
Abstract:
The present invention provides a method for enhancing service signals transmitted by a DCE, such as a Modem, to a DTE user. Since any transmission from a remote computer to a DTE user through a wireless communication network can be encoded with additional information, use of an AT compatible modem in conjunction with a wireless communication network adds a new dimension of information that can be displayed to the DTE user. The present invention also includes a method for ensuring effective data transfer from a DCE to a DTE user. When a DTE receives a connection service signal it will often require several internal adjustments before it can accept data. Because data received by a radio-based modem is received in packets, under certain conditions data will be waiting to be transmitted to the user immediately after the modem enters a data transfer state. The method of this invention includes the steps of transmitting a service signal to the DTE indicating that the modem has entered a data transfer state and delaying for a predetermined time after transmitting the data-transfer-state signal before transmitting data from the modem to the DTE.
