First Claim
Patent Images
1. A method of telephony translations and route selection comprising:
- receiving a call request, the call request comprising input information being for a telephony call;
determining at least one call attribute from the input information;
transmitting a routing policy request to query a route database;
responsive to the routing policy request, receiving a routing policy response, the response comprising at least one routing parameter; and
using the at least one routing parameter to influence call set up.

Abstract
A method and apparatus for providing access device input format independent translations and route selection for telephony calls. A call request is received, the call request comprising input information being for a telephony call. At least one call attributes is then determined from the input information and a routing policy request is transmitted to query a route database. Responsive to the routing policy request a routing policy response is received, the response comprising at least one routing parameter. The at least one routing parameter is used to influence call set up. Route selection is therefore not constrained by the service request input format.

13. An apparatus for route selection in a communications network, comprising:
-
a controller adapted to derive at least one call attribute from a call request for a telephony transmission; and
a route database communicatively coupled to said controller, said route database being adapted to receive a routing policy request from said controller, and transmit a routing policy response having at least one routing parameter, said routing policy response generated responsive to a routing policy request based on the at least one call attribute.

24. An apparatus for route selection in a communications network, comprising:
-
means for receiving a call request, the call request being for a telephony call;
means for deriving at least one call attribute from the call request;
means for transmitting a routing policy query request to a route database, the routing policy request based on the at least one call attribute;
means for receiving a routing policy response from a route database, the routing policy response comprising at least one routing parameter; and

25. A system for call setup over a communications network, the system comprising:
-
(a) an ingress call server having a receiver for receiving a call request for a telephony call, the call request comprising alias information for the telephony call;
the ingress call server comprising;
a controller adapted to derive at least one call attribute from the call request; and
a transmitter for transmitting a routing policy query request comprising the at least one call attribute, and (b) a route database communicatively coupled to the ingress call server, the route database comprising;
a receiver for receiving a routing policy query request;
a controller adapted to translate the at least one call attribute to endpoint routing information; and
a transmitter for transmitting a routing policy query response comprising the endpoint routing information.

27. An article including one or more machine-readable storage media containing instructions to manage communications apparatus in a communications network, the instructions when executed causing a controller to:
-
receive a call request, the call request being for a telephony call;
derive at least one call attribute from the call request;
transmit a routing policy query request to a routing policy server, the routing policy request defining the at least one call attribute;
receive a routing policy response from the routing policy server, the routing policy response comprising at least one routing parameter; and
transmit the at least one routing parameter to influence control of call set up.
