Computer system for use with a wireless data communication network
First Claim
1. A method of indicating to data terminal equipment (DTE) a source of data transmitted over a data communications network and through a gateway to data communications equipment (DCE) that is configurable to receive such data from the gateway and is connected to the DTE, the method comprising the steps of:
- (a) preparing a session request from a request initiator that is to be transmitted via the data communications network through the gateway to the DCE, wherein the session request includes identification data that identifies the source of the session request;
(b) transmitting the session request over the network through the gateway to the DCE;
(c) determining whether the session request is valid;
(d) if the session request is valid, preparing a service signal from the DCE to the DTE in response to the session request;
(e) enhancing the service signal by adding an identifier that represents at least a part of the identification data to the service signal;
(f) transmitting the service signal that has been enhanced in the enhancing step to the DTE; and
(g) processing the service signal at the DTE.

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.

21. A system for enhancing service signals that are transmitted between a modem and data terminal equipment (DTE) associated with the modem by providing to the DTE an indication of the source of data transmitted over a data communications network and through a gateway to the modem, the system including:
-
means for detecting a session request from a request initiator that is transmitted via the data communications network through the gateway to the modem, wherein the session request includes identification data that identify the source of the session request; validating means for determining whether the session request is valid; means for preparing a service signal from the modem to the DTE in response to the session request and in response to the determination made by the validating means; means for enhancing the service signal by adding an identifier that represents at least a part of the identification data to the service signal; means for transmitting the service signal to the DTE; and means for processing the service signal at the DTE. - View Dependent Claims (22)
