Abstract

Abstract The present invention is directed to a system that allows a subscriber to take a telephone call over the Internet when the subscriber telephone line is busy servicing a browser-based Internet session without requiring that the subscriber disconnect or terminate the Internet session. The system transfers a telephone call to a subscriber telephone line that is busy to a call servicing platform where the platform determines if the subscriber line is busy due to an interactive Internet session. When a session is in progress, the platform informs the subscriber via a network message to the subscriber's personal computer involved in the session that a call is waiting. If the subscriber accepts the call, the platform digitizes the speech of the caller and sends it to the computer where it is output to the subscriber. At the same time, the computer digitizes the speech of the subscriber and sends it to the platform, where it is output to the caller. The system can also allow the subscriber to screen the caller by listening to the caller as a message is recorded. The network session can continue during the transfer of the speech or resume after the call is finished, that is, the session need not be terminated to free the telephone line to carry the call.

Claims Analysis

Total Claims: 20
Claim 1
Independent Claim 73 words
A system, comprising: a packet-switched network; a computer coupled to and conducting a session with said network over a telephone line; a telephone system transferring a telephone call away from the telephone line when the telephone line is busy; and a call servicing system coupled to said telephone system and said network, accepting the transferred call and establishing a communication link with said computer over said network with the link carrying the call.
Claim 2
Dependent Claim 19 words
A system as recited in claim 1, wherein the link is a voice communication link established during the session.
Claim 3
Dependent Claim 29 words
A system as recited in claim 1 or claim 2, wherein said call servicing system stores a message of the caller when the computer declines to establish the link.
Claim 4
Independent Claim 28 words
A system as recited in any of the preceding claims, wherein said computer sends a network address of said computer to said system when the session is initiated.
Claim 5
Independent Claim 26 words
A system as recited in any of the preceding claims, wherein the call is a single direction call from the call servicing system to the computer.
Claim 6
Independent Claim 18 words
A system as recited in any of the preceding claims, wherein said call servicing system performs echo cancellation.
Claim 7
Independent Claim 31 words
A system as recited in any of the preceding claims, wherein said computer and said call servicing system perform silence detection and do not send speech packets when silence is detected.
Claim 8
Independent Claim 167 words
A system, comprising: an Internet network; a computer coupled to and conducting a browsing session with said network over a telephone line; a telephone system transferring a telephone call away from the telephone line when the telephone line is busy; and a call servicing system coupled to said telephone system and said network accepting the transferred call, informing said computer that the call is waiting, establishing a voice communication packet-switched link with said computer over said network using the telephone line with the link carrying speech of the call when the waiting call is accepted by said computer, the voice communication link being established during the session, said call servicing system storing a message of the caller when said computer declines to establish the link, said computer sending a network address of said computer to said call servicing system when the session is initiated, the network address being used to establish the link and the session continuing over the telephone line during the call over the link.
Claim 9
Independent Claim 75 words
A system, comprising: a packet-switched network; a computer coupled to and conducting a session with said network; a telephone system transferring a telephone call away from a telephone line when a called telephone of the telephone line does not answer; and a call servicing system coupled to said telephone system and said network accepting the transferred call and establishing a communication link with said computer over said network with the link carrying the telephone call.
Claim 10
Independent Claim 40 words
A method, comprising: detecting that a telephone line of a computer user is busy in an Internet session; establishing a communication link to the computer over the Internet; and conducting a telephone call over the communication link during the session.
Claim 11
Independent Claim 19 words
A method, comprising: conducting a telephone call through a computer involved in a packet-switched network session during the session.
Claim 12
Dependent Claim 27 words
A method as recited in claim 11, wherein the telephone call and the session are carried by a same telephone line between the computer and the network.
Claim 13
Dependent Claim 22 words
A method as recited in claim 12, further comprising multi-tasking the session and the call with the call having a higher priority.
Claim 14
Dependent Claim 18 words
A method as recited in claim 13, further comprising assigning call packets a higher priority than session packets.
Claim 15
Independent Claim 63 words
A method, comprising: storing a network address of a computer when the computer initiates a network session; detecting that a telephone line to the computer is busy; determining that the session is in progress when the address is stored; establishing a communication link with the computer using the address during the session; and conducting a telephone call over the link during the session.
Claim 16
Independent Claim 41 words
