Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
157 words
A method for selecting a gateway proximal to a network access point that satisfies a predefined call service on a hybrid network, wherein the hybrid network includes a circuit switched network, a packet switched network and a directory service to route a call, comprising: transmitting a query including a type of call service to the directory service to identify a plurality of gateways between the packet switched network and circuit switched network that match the predefined call service criteria; sending a message to each of said plurality of gateways to obtain a trace route; ranking the plurality of gateways based on the trace route of each of said plurality of gateways; translating an identifier of a destination of the call from a listing of telephone numbers and associated internet protocol addresses in the directory service; selecting a gateway with a highest ranking from said plurality of gateways; and attempting to route the call over the selected gateway.
Claim 2
Independent Claim
157 words
A method for selecting a gateway proximal to a network access point that satisfies a predefined call service on a hybrid network, wherein the hybrid network includes a circuit switched network, a packet switched network and a directory service to route a call, comprising: transmitting a query including a type of call service to the directory service to identify a plurality of gateways between the packet switched network and circuit switched network that match the predefined call service criteria; sending a message to each of said plurality of gateways to obtain a trace route; ranking the plurality of gateways based on the trace route of each of said plurality of gateways; translating an identifier of a destination of the call from a listing of telephone numbers and associated internet protocol addresses in the directory service; selecting a gateway with a highest ranking from said plurality of gateways; and attempting to route the call over the selected gateway.
Claim 3
Dependent Claim
32 words
The method of claim 1 , further comprising: attempting to route the call over a next ranked gateway upon a failure of said attempting to route the call over the selected gateway.
Claim 4
Dependent Claim
76 words
The method of claim 1 , wherein said ranking includes: ranking highest any of said plurality of gateways that are accessible without traveling through any intervening router; ranking all of said plurality of gateways that are accessible without traveling through any intervening router in order of lowest latency, if more than one of said plurality of gateways are accessible without traveling through any intervening router; and ranking lowest any remaining gateways of said plurality of gateways.
Claim 5
Dependent Claim
29 words
The method of claim 3 , wherein said ranking lowest any remaining gateways further includes: ranking any remaining gateways of said plurality of gateways in order of lowest latency.
Claim 6
Dependent Claim
171 words
A hybrid network that includes a circuit switched communications network and a packet transmission network coupled to the circuit switched communications network, the hybrid network comprising: a directory service; a plurality of gateways connecting the circuit switched communication network and the packet network; and a call router coupled to the circuit switched communications network with logic that transmits a query including a type of call service to the directory service to identify a plurality of gateways between the packet transmission network and the circuit switched communications network that match predefined call service criteria, sends a message to each of said plurality of gateways to obtain a trace route, ranks the plurality of gateways based on the trace route of each of said plurality of gateways, translates an identifier of a destination of the call from a listing of telephone numbers and associated internet protocol addresses in the directory service, selects a gateway with a highest ranking from said plurality of gateways, and attempts to route the call over the selected gateway.
Claim 7
Dependent Claim
171 words
A hybrid network that includes a circuit switched communications network and a packet transmission network coupled to the circuit switched communications network, the hybrid network comprising: a directory service; a plurality of gateways connecting the circuit switched communication network and the packet network; and a call router coupled to the circuit switched communications network with logic that transmits a query including a type of call service to the directory service to identify a plurality of gateways between the packet transmission network and the circuit switched communications network that match predefined call service criteria, sends a message to each of said plurality of gateways to obtain a trace route, ranks the plurality of gateways based on the trace route of each of said plurality of gateways, translates an identifier of a destination of the call from a listing of telephone numbers and associated internet protocol addresses in the directory service, selects a gateway with a highest ranking from said plurality of gateways, and attempts to route the call over the selected gateway.
Claim 8
Dependent Claim
34 words
The hybrid network of claim 5 , wherein said logic attempts to route the call over a next ranked gateway upon a failure of the attempt to route the call over the selected gateway.
Claim 9
Dependent Claim
76 words
The hybrid network of claim 5 , wherein said logic ranks highest any of said plurality of gateways that are accessible without traveling through any intervening router, ranking all of said plurality of gateways that are accessible without traveling through any intervening router in order of lowest latency, if more than one of said plurality of gateways are accessible without traveling through any intervening router; and ranks lowest any remaining gateways of said plurality of gateways.
Claim 10
Dependent Claim
25 words
The hybrid network of claim 7 , wherein said logic ranks lowest any remaining gateways of said plurality of gateways in order of lowest latency.
Claim 11
Dependent Claim
19 words
The method of claim 1 , wherein the predefined call service comprises parameters based on a quality of service.
Claim 12
Dependent Claim
19 words
The method of claim 1 , further comprising: matching the predefined call service by accessing a gateway registration scheme.
