Providing multimedia services over a cable network
First Claim
1. An access switch comprising:
- at least one cable modem termination system, wherein the cable modem termination system, when coupled to a hybrid-fiber coaxial cable network, is in communication with a media terminal adapter, wherein the cable modem termination system includes a gate manager executing thereon;
a route server, in communication with the cable modem termination system, that includes a common open policy service client executing on the route server;
a network interface module, in communication with the cable modem termination system and the route server, that, when the network interface module is coupled to a network, communicates common open policy service messages between the common open policy service client and a call management server included in the network;
wherein when a first common open policy service message that includes a gate command is received by the common open policy service client, the common open policy service client sends a second message derived from the first common open policy service message to the gate manager; and
wherein the gate manager receives the second message and processes the gate command.

Abstract
An access switch includes a cable modem termination system with a gate manager executing thereon and a route server, in communication with the cable modem termination system, that includes a common open policy service client executing on the route server. The switch further includes a network interface module, in communication with the cable modem termination system and the route server, that, when the network interface module is coupled to a network, communicates common open policy service messages between the common open policy service client and a call management server included in the network. When a first common open policy service message that includes a gate command is received by the common open policy service client, the common open policy service client sends a second message derived from the first common open policy service message to the gate manager. The gate manager receives the second message and processes the gate command.

11. A route server for use in an access switch that includes at least one cable modem termination system and a network interface module for coupling the route server and the cable modem termination system to a network, wherein the cable modem termination system includes a gate manager executing thereon, the route server comprising:
-
a route look-up subsystem; and
a common open policy service client, wherein when the common open policy service client receives, from a call management server included in the network, a common open policy service message that includes a gate command, the common open policy service client sends a second message derived from the common open policy service message to the gate manager, wherein the gate manager process the gate command. - View Dependent Claims (12, 13, 14, 15)

16. A method of processing common open policy service messages, the method comprising:
-
receiving a common open policy service message from a call management server, wherein the common open policy service message includes a gate command;
assembling a second message that includes the gate command, wherein the second message is derived from the common open policy service message;
sending the second message to a gate manager executing on a cable modem termination system; and
when a valid response message is received from the gate manager, assembling an acknowledgement common open policy service message derived from the valid response message and sending the acknowledgement common open policy service message to the call management server. - View Dependent Claims (17, 18, 19, 20)

21. A route server for use in an access switch that includes at least one cable modem termination system and a network interface module for coupling the route server and the cable modem termination system to a network, wherein the cable modem termination system includes a gate manager executing thereon, the route server comprising:
-
a route look-up subsystem; and
a common open policy service client that;
receives a common open policy service message from the call management server, wherein the common open policy service message includes a gate command;
assembles a second message that includes the gate command, wherein the second message is derived from the common open policy service message;
sends the second message to the gate manager; and
when a valid response message is received from the gate manager, assembles an acknowledgement common open policy service message derived from the valid response message and sends the acknowledgement common open policy service message to the call management server. - View Dependent Claims (22, 23, 24, 25)

26. A cable modem termination system for use in an access switch that includes a route server on which a common open policy service client executes and a network interface module for coupling the route server and the cable modem termination system to a network, the cable modem termination system comprising:
-
a data over cable service interface specification subsystem that, when the cable modem termination system is coupled to a hybrid-fiber coaxial cable network, communicates with at least one cable modem over the hybrid-fiber coaxial cable network, and that, when the network module is coupled the managed internet protocol network, communicates with the managed internet protocol network via the network module, wherein the data over cable service interface specification subsystem includes;
a quality-of-service policy manager subsystem;
a classifier subsystem; and
a protocol header suppression subsystem; and
a gate manager that receives a message from the common open-policy service client, wherein the message includes a gate command derived from a common open policy service message received by the common open policy service client, wherein the gate manager processes the gate command. - View Dependent Claims (27, 28, 29, 30, 31)
