Method and apparatus for providing internet call waiting with voice over internet protocol
First Claim
1. A method for providing an internet call waiting—
- voice over internet protocol service comprising;
receiving at a service switching point an incoming telephone call to a subscriber connected to an internet, wherein the incoming call activates a trigger provisioned on the service switching point, which sends a first query to a service control point;
forwarding bridging information from the service control point to a service node;
receiving an internet protocol call from the subscriber at a gateway;
placing a gateway call from the gateway to the service switching point in response to the internet protocol call from the subscriber;
routing the gateway call to the service node;
forwarding the incoming telephone call from the service switching point to the service node; and
connecting the gateway call and the incoming telephone call at the service node.

Abstract
An Internet Call Waiting—Voice over Internet Protocol (ICW-VOIP) service that uses a service control point and service node of a Public Switched Telephone Network (PSTN), acting as a gatekeeper and bridge respectively, to enable ICW subscribers to answer telephone calls during an internet session without having to disconnect internet access. The primary network components of the ICW-VOIP service comprise a proxy firewall, a service node, and a gateway. When a PSTN call is placed to a subscriber whose line is being used for internet access, the service control point accesses the subscriber'"'"'s internet address from a database and transmits a message over the internet to the subscriber giving the subscriber the option to accept the call as a VOIP call. Once accepted, the subscriber places an H.323 call through the gateway to the service node. The service control point also forwards the PSTN call to the service node. Using bridging information, the service node matches the subscriber H.323 call and PSTN call and bridges them together to provide a VOIP connection.

9. A method for providing an internet call waiting—
- voice over internet protocol (ICW-VOIP) service comprising;
receiving at a service switching point an incoming call from a PSTN caller to a subscriber connected to an internet; sending a query from the service switching point to a service control point; providing options associated with the incoming call to the subscriber, wherein one of the options is “
accept the incoming call over the VOID and maintain internet connection,”wherein if the “
accept the incoming call over the VOID and maintain internet connection”
option is selected, the method further comprises;forwarding bridging information from the service control point to a service node; receiving an internet protocol call from the subscriber at a gateway; placing a gateway call from the gateway to the service switching point in response to the internet protocol call from the subscriber; sending a second query from the service switching point to the service control point; sending a routing instruction from the service control point to the service switching point; forwarding the gateway call from the service switching point to the service node according to the routing instruction; forwarding the incoming call from the service switching point to the service node; and bridging the incoming call and the gateway call at the service node. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A system for providing an internet call waiting—
- voice over internet protocol service comprising;
a public switched telephone network (PSTN) infrastructure including a service switching point connected to a service node, and a service control point connected to the service switching point and the service node, wherein the PSTN infrastructure is to be connected to an internet network including an internet service provider connected to an internet and a gateway connected to the internet, wherein the gateway is to converts internet protocol voice communications into PSTN voice communications, and wherein the service node is to act as a bridge and to connect an incoming call from a PSTN caller to a subscriber connected to the internet, through the gateway. - View Dependent Claims (17, 18, 19)
