First Claim
1. A telephone system comprising:
- a session controller; and
one or more nodes coupled to the session controller, wherein each node includes a service gateway coupled to one or more terminals;
wherein each service gateway of the one or more nodes is comprised of at least a reflector, propagator, and control signal distributor, and wherein each service gateway of the one or more nodes includes its own said reflector, own said propagator, and own said control signal distributor;
wherein a first terminal of a first node is configured to convey a media packet to a first service gateway during a page activity;
wherein in response to determining one or more terminating terminals are associated with one or more remote nodes, the first service gateway is configured to propagate the media packet to one or more other service gateways associated with the one or more terminating terminals;
wherein in response to determining one or more terminating terminals are included in the first node, the first service gateway is configured to reflect the media packet back to the one or more terminating terminals included in the first node;
wherein the first terminal of the first node is configured to convey a start page request to the first service gateway to initiate a page activity between the first terminal and one or more terminating terminals, and wherein the first service gateway is configured to convey the start page request to the session controller; and
wherein in response to receiving the start page request from the first service gateway, the session controller is configured to convey one or more first control signals to one or more respective service gateways, wherein each of said respective service gateways is different from the first service gateway.

Abstract
An IP-telephony system including one or more nodes coupled to a session controller. Each node includes a service gateway coupled to one or more terminals. A first terminal conveys a start page request initiating a page activity between itself and one or more terminating terminals. The session controller receives the start page request and in response, conveys first control signals to one or more service gateways, each first control signal containing information identifying which of the terminals associated with a service gateway is a terminating terminal. In response to the first control signal, each service gateway conveys second control signals to its associated terminating terminals. The first terminal conveys a media packet to the first service gateway during a page activity. The first service gateway forwards the media packet to one or more designated terminating terminals.

12. An IP-telephony service gateway comprising:
-
a reflector; a propagator; a packet transceiver unit; and a control signal distributor; wherein in response to the service gateway receiving a media packet from a first terminal of a first node during a page activity and the service gateway determining one or more terminating terminals are associated with one or more remote nodes, the propagator is configured to propagate the media packet to one or more other service gateways associated with the one or more terminating terminals; wherein in response to the service gateway determining one or more terminating terminals are included in the first node, the reflector is configured to reflect the media packet back to the one or more terminating terminals included in the first node; wherein the service gateway is further configured to; receive a first start page request from a first terminal, said first start page request initiating a page activity between the first terminal and one or more terminating terminals, and wherein the first start page request includes information identifying the one or more terminating terminals, forward the first start page request to a session controller; and receive from the session controller a first control signal containing information identifying which of the one or more terminals associated with the service gateway is a terminating terminal, wherein the first control signal is conveyed by the session controller in response to a second start page request from a different service gateway. - View Dependent Claims (13)

14. A method of paging in an IP-telephony system, the method comprising:
-
conveying a media packet from a first terminal of a first node to a first service gateway during a page activity; wherein in response to determining one or more terminating terminals are associated with one or more remote nodes, propagating the media packet from the first service gateway to one or more other service gateways associated with the one or more terminating terminals; wherein in response to determining one or more terminating terminals are included in the first node, reflecting the media packet from the first service gateway back to the one or more terminating terminals included in the first node; receiving a start page request at the first service gateway initiating a page activity between a first terminal and one or more terminating terminals; forwarding the start page request from the service gateway to a session controller; and in response to receiving the start page request, the session controller conveying one or more first control signals to one or more respective service gateways, wherein each of said respective service gateways is different from the first service gateway. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A method of coordinating paging in an IP-telephony service gateway, the method comprising:
-
wherein a first terminal of a first node is configured to convey a media packet to the service gateway during a page activity; wherein in response to the service gateway receiving a media packet and the service gateway determining one or more terminating terminals are associated with one or more remote nodes, the propagator is configured to propagate the media packet to one or more other service gateways associated with the one or more terminating terminals; wherein in response to the service gateway determining one or more terminating terminals are included in the first node, the reflector is configured to reflect the media packet back to the one or more terminating terminals included in the first node; receiving a first start page request from a first terminal, said first start page request initiating a page activity between the first terminal and one or more terminating terminals; forwarding the first start page request to a session controller; and receiving from the session controller a first control signal containing information identifying which of the one or more terminals associated with the service gateway is a terminating terminal, wherein the first control signal is conveyed by the session controller in response to a second start page request from a different service gateway. - View Dependent Claims (22, 23)

24. A non-transitory computer readable storage medium containing instructions that, when executed by a processor in an IP-telephony service gateway, enable the gateway to:
-
wherein in response to receiving a media packet from a first terminal of a first node during a page activity and determining one or more terminating terminals are associated with one or more remote nodes, propagate the media packet to one or more other service gateways associated with the one or more terminating terminals; wherein in response to determining one or more terminating terminals are included in the first node, reflect the media packet back to the one or more terminating terminals included in the first node; receive a first start page request from a first terminal, said first start page request initiating a page activity between the first terminal and one or more terminating terminals; forward the first start page request to a session controller; and receive from the session controller a first control signal containing information identifying which of the one or more terminals associated with the service gateway is a terminating terminal, wherein the first control signal is conveyed by the session controller in response to a second start page request from a different service gateway. - View Dependent Claims (25)
