Network and method providing an indication of network capabilities to a user for special number calls
View Patent ↗Networks and methods are disclosed for providing an indication of the capability of a communication network for serving special number calls. Before a user places a special number call, the communication network determines the capability of the communication network for serving a special number call, and provides the indication of the network capability to the user. The user is thus kept aware of the quality of the special number service available to them through the communication network.
1. A method of providing an indication of the capability of a communication network to serve special number calls before special number calls are placed over the communication network, the method comprising:
determining location information for a VoIP device of a user being served by a VoIP network;
determining routing information for a simulated special number call to route the simulated special number call from the VoIP device through the VoIP network to an answering point;
determining a network capability of the communication network for serving special number calls from the VoIP device based on at least the location information and the routing information; and
providing an indication of the network capability to the VoIP device to notify the user as to the network capability of the communication network for serving an actual special number call prior to the user placing the actual special number call.
2. The method of claim 1 wherein determining a network capability of the communication network comprises:
processing the location information to identify a location of the VoIP device and an uncertainty of the location of the VoIP device; and
determining the network capability of the communication network based on the location of the VoIP device and the uncertainty of the location.
3. The method of claim 1 wherein determining a network capability of the communication network comprises:
identifying an answering point for the simulated special number call and an amount of data that can be provided to the identified answering point; and
determining the network capability of the communication network based on the identified answering point and the amount of data that can be provided to the identified answering point.
4. The method of claim 1 wherein determining a network capability of the communication network comprises:
determining if a call back number is identified for the simulated special number call; and
determining the network capability of the communication network based on whether the call back number is identified.
5. The method of claim 1 wherein determining a network capability of the communication network for serving the simulated special number call comprises:
identifying an answering point to handle the simulated special number call;
determining the capabilities of the answering point to handle the simulated special number call; and
determining the network capability of the communication network based on the capabilities of the identified answering point.
6. The method of claim 1 wherein the steps of the method are initiated responsive to the VoIP device registering with the VoIP network.
7. The method of claim 1 further comprising:
receiving the indication of the network capability in the VoIP device; and
displaying the indication of the network capability to the user to notify the user of the network capability prior to the user placing an actual special number call.
8. The method of claim 7 wherein displaying the indication of the network capability comprises at least one of illuminating an LED, displaying a web page, or displaying a text message.
9. The method of claim 1 further comprising:
restricting VoIP service to the VoIP device responsive to the network capability not meeting defined capability standards.
10. The method of claim 1 wherein the special number call comprises a 9-1-1 call.
11. A communication network adapted to provide an indication of the capability of a communication network to serve special number calls before special number calls are placed over the communication network, the communication network comprising:
a VoIP server adapted to provide VoIP service to a VoIP device;
a positioning system adapted to determine location information for the VoIP device of a user, and to determine routing information for a simulated special number call to route the simulated special number call from the VoIP device through the VoIP server to an answering point; and
a capability determination system adapted to determine a network capability of the communication network for serving special number calls from the VoIP device based on at least the location information and the routing information, and to provide an indication of the network capability to the VoIP device to notify the user as to the network capability of the communication network for serving an actual special number call prior to the user placing the actual special number call.
12. The communication network of claim 11 wherein the capability determination system is further adapted to:
process the location information to identify a location of the VoIP device and an uncertainty of the location of the VoIP device; and
determine the network capability of the communication network based on the location of the VoIP device and the uncertainty of the location.
13. The communication network of claim 11 wherein the capability determination system is further adapted to:
identify an answering point for the simulated special number call and an amount of data that can be provided to the identified answering point through the VoIP network; and
determine the network capability of the communication network based on the identified answering point and the amount of data that can be provided to the identified answering point.
14. The communication network of claim 11 wherein the capability determination system is further adapted to:
determine if a call back number is identified for the simulated special number call; and
determine the network capability of the communication network based on whether the call back number is identified.
15. The communication network of claim 11 wherein the capability determination system is further adapted to:
identify an answering point to handle the simulated special number call;
determine the capabilities of the answering point to handle the simulated special number call; and
determine the network capability of the communication network based on the capabilities of the identified answering point.
16. The communication network of claim 11 wherein the capability determination system is further adapted to determine the network capability responsive to the VoIP device registering with the VoIP server.
17. The communication network of claim 11 wherein the VoIP server is further adapted to:
restrict VoIP service to the VoIP device responsive to the network capability not meeting defined capability standards.
18. The communication network of claim 11 wherein the special number call comprises a 9-1-1 call.
