Internet access is provided to a multimedia terminal (101, 102, 103, 104) supporting the H.320 protocol through a gateway server (125) that is connected to the Internet. The data stream of the H.320 bearer channel (ISDN phone line or switched 56 kbps facilities) is used for the exchange of data between the accessing terminal and the gateway server, which outputs and receives such data onto and from the Internet, respectively. The gateway server is implemented to function to directly exchange on the H.320 data stream information requests and responsive data in the TCP/IP format used for Internet transport. Alternatively, the gateway server is implemented to function as a proxy to which requests are passed from the terminal over the H.320 data stream, and where function calls are made and locally converted to TCP/IP format for transport onto the Internet. For responsive data received from the Internet, the proxy gateway server removes the TCP/IP formatting and transmits the resultant data back to the terminal over the H.320 data stream.

[ The invention claimed is:] [1.] In a telecommunications network, a method of providing access to the Internet to a multimedia terminal capable of communicating voice, video and data signals over separate voice, video and data streams, respectively, on a bearer channel in accordance with a standardized H.320 protocol, the method comprising the steps of:establishing a data connection between the multimedia terminal and a gateway server that is remote from the terminal and is connected to the Internet, the data connection being at least in part over the bearer channel on only at least a portion of the data stream, for transmitting data associated with a request and a response to such request to and from a provider connected on the Internet, respectively, while the multimedia terminal simultaneously maintains the capability of transmitting and receiving the video and voice signals on the video and voice streams, respectively, on the bearer channel;receiving, at the gateway server from the multimedia terminal over the data connection, the data associated with the request;transmitting, by the gateway server, onto the Internet, an executed request initiated by the terminal to the provider in a format that is compatible for transmission on the Internet;receiving, at the gateway server, from off the Internet from the provider, a response to the request; and;forwarding, by the gateway server, the response to the request to the terminal over the data connection.
