Abstract
Abstract A gateway architecture for data communication over bandwidth-constrained and charge-by-use networks (10) uses a C -- Gate application (14) located between a client application (12) and a bandwidth-constrained network (22), and an S -- Gate application (20) located between the bandwidth-constrained network (22) and an Internet server (26), to send and receive data in an efficient manner across the bandwidth-constrained network (22) by converting the native protocols of the client application (12) and the Internet server (26) to a bandwidth-efficient protocol. The C -- Gate application (14) and S -- Gate application (20) also act to reconvert data packets from the bandwidth-efficient protocol back to the native transport protocols for data communication to the Internet server (26) and the client application (12).

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
153 words
A method for effecting data communications between a remote node and a host, comprising the steps of: exchanging data in a first exchanging step between a client application at said remote node using the TCP/IP communications protocol which is resident on said remote node and a first proxy or gateway, wherein said first exchanging step further comprises the step of compressing said data; converting said TCP/IP communications protocol resident on said remote node into a bandwidth-efficient protocol prior to transmission of said data communications from said first proxy or gateway to said host; reconverting said bandwidth-efficient protocol back to said TCP/IP communications protocol at a second proxy or gateway; and exchanging data in a second exchanging step between said second proxy or gateway and an application at said host in said TCP/IP communications protocol which is resident on said host, wherein said second exchanging step further comprises the step of decompressing said data.
Claim 2
Independent Claim
153 words
A method for effecting data communications between a remote node and a host, comprising the steps of: exchanging data in a first exchanging step between a client application at said remote node using the TCP/IP communications protocol which is resident on said remote node and a first proxy or gateway, wherein said first exchanging step further comprises the step of compressing said data; converting said TCP/IP communications protocol resident on said remote node into a bandwidth-efficient protocol prior to transmission of said data communications from said first proxy or gateway to said host; reconverting said bandwidth-efficient protocol back to said TCP/IP communications protocol at a second proxy or gateway; and exchanging data in a second exchanging step between said second proxy or gateway and an application at said host in said TCP/IP communications protocol which is resident on said host, wherein said second exchanging step further comprises the step of decompressing said data.

Claim 7
Dependent Claim
180 words
A gateway architecture for data communication over network between a remote node and a host, comprising: a first proxy or gateway located between a client application and said network, wherein said first proxy or gateway receives requests and gathers information from said client application using the TCP/IP communications protocol which is resident on said remote node, and wherein said information is first compressed and then converted to a bandwidth-efficient protocol prior to communication over said network; and a second proxy or gateway located between said network and said host, wherein said second proxy or gateway receives requests from said first proxy or gateway, and wherein said second proxy or gateway sends and receives messages to and from said host in said TCP/IP communications protocol resident on said host, wherein said information is first reconverted from said bandwidth-efficient protocol back to said TCP/IP protocol and then decompressed after receipt over said network; wherein said first proxy or gateway sends and receives messages to and from said second proxy or gateway over said network using an efficient transport mechanism other than TCP/IP.
Claim 8
Dependent Claim
180 words
A gateway architecture for data communication over network between a remote node and a host, comprising: a first proxy or gateway located between a client application and said network, wherein said first proxy or gateway receives requests and gathers information from said client application using the TCP/IP communications protocol which is resident on said remote node, and wherein said information is first compressed and then converted to a bandwidth-efficient protocol prior to communication over said network; and a second proxy or gateway located between said network and said host, wherein said second proxy or gateway receives requests from said first proxy or gateway, and wherein said second proxy or gateway sends and receives messages to and from said host in said TCP/IP communications protocol resident on said host, wherein said information is first reconverted from said bandwidth-efficient protocol back to said TCP/IP protocol and then decompressed after receipt over said network; wherein said first proxy or gateway sends and receives messages to and from said second proxy or gateway over said network using an efficient transport mechanism other than TCP/IP.
