Abstract

A data transmission routing system which allows a terminal user to access an initial host within a computer network, the initial host determines a preferred target host to respond to the user'"'"'s requests, the initial host communicates with a terminal or gateway node the target host'"'"'s address, and the terminal or gateway node makes a connection wth the target host. Once the terminal or gateway node is in communication with the target host, the initial host forwards through the terminal or gateway node user profile information to the target host. The initial host is then disconnected and communication then proceeds with the user in contact with the target host through the terminal or gateway node. The entire process may take less than a second or two and the user may never know that a call deflection to a new host has occurred.

Claims

1. A computer system in which a terminal user making a request for information or other assistance available through a computer network, accesses a first host within a multihost network, said system comprising:

a PAD node within the network to receive a call from the terminal user and connect the user to the first host;

first program means within the first host for processing profile information from the user and selecting which host within the multihost network should handle the user'"'"'s request; and

second program means within the PAD node for responding to the first host and contacting a selected target host independent of user instruction, wherein after a connection is made with the target host the terminal user'"'"'s connection with the first host is deflected to the target host.

2. The computer system of claim 1, further comprising:

at least one host adjacent node connected to each host in the network, to receive communications from the PAD node and convey said communications to its respective host; and

third program means within the host adjacent nodes for interaction with the first program means within each host and the second program means within the PAD node.

3. The computer system of claim 1, wherein the first program means is capable of disconnecting the first host from the PAD node after the user has been deflected to the target host.

4. The computer system of claim 1, further comprising:

means associated with the first program means and the second program means to transfer the user profile information to the target host independent of user instruction.

5. The computer system of claim 1, further comprising:

the first program means also within the target host to enable the target host to deflect the user to a second target host.

6. The computer system of claim 1, wherein the terminal user is a regular subscriber to the multihost network.

7. The computer system of claim 1, wherein the terminal user is external to the multihost network.

8. The system of claim 1, wherein the target host is a foreign host outside the control of the first host owner but within the network.

9. The system of claim 1, wherein the first host and the target host are in separate cities.

10. A method for switching a terminal user, making a request, from one computer host to another computer host within a multihost network, said method comprising the steps of:

the terminal user calling a first host within the network, the call being received through a PAD node which contacts the first host, such that the user, the PAD node, and the first host are simultaneously in communication;

the first host learning profile information about the user and the user'"'"'s request;

the first host determining a target host within the network that should respond to the user'"'"'s request and informing the PAD node of the target host address;

the PAD node contacting the target host; and

the first host disconnecting from the PAD node.

11. The method of claim 10, further comprising the step of:

the first host sharing information about the user with the target host prior to the first host disconnecting.

12. The method of claim 10, further comprising the step of:

the target host deflecting the user'"'"'s call to a second target host.

13. The method of claim 10, wherein the terminal user knows the desired target host.

14. The method of claim 10, wherein the terminal user does not know the target host.

15. The method of claim 10, wherein the user is unaware that the user'"'"'s call to the first host has been deflected to the target host.
