Abstract

A system and method for routing IP-based messaging, voice and video calling, comprising detecting network parameters of a network that a device is connected to, detecting a location of the device and routing the call based on the network parameters and the location.

Claims

1. A telecommunications system, comprising:

a handheld device having a processor, a memory device, a user input device, a speaker and a microphone, the processor configured to execute an algorithm that causes the processor to detect one or more network parameters of a network that the handheld device is connected to;

the memory device configured by a configuration server of a carrier to include a subscriber assigned number and at least one home IMS proxy server address, at least one domestic IMS proxy server address, and at least one international IMS proxy server address using a proxy call session control function (P-CSCF) associated with the subscriber assigned number without accessing a carrier controlled network;

the processor further configured to detect a location of the handheld device; and

the processor further configured to select an IMS proxy server address from the at least one IMS proxy server address and route a call to the selected IMS proxy server address based on the one or more network parameters and the location;

wherein the processor is configured to route the call if the one or more network parameters includes a home network identifier and if it is determined that a home network associated with the home network identifier is available.

2. The telecommunications system of claim 1, wherein the processor is further configured to implement an encryption feature as a function of a secure or non-secure network type, an application type, and a handheld device location after selection of a network P-CSCF as a function of the handheld device location.

3. The telecommunications system of claim 1, wherein the processor is further configured to implement a virtual private network as a function of the one or more network parameters after selection of a network P-CSCF as a function of a handheld device location.

4. The telecommunications system of claim 1, wherein the processor is further configured to implement encryption as a function of the one or more network parameters after selection of a network P-CSCF as a function of the handheld device location.

5. The telecommunications system of claim 1, wherein the processor is configured to route the call to a national roaming over the top server or an international roaming over the top server based on the one or more network parameters and the location using a routing algorithm in response to a determination by the handheld device that a communication session should be established with a P-CSCF associated with the national roaming over the top server or the international roaming over the top server.

6. The telecommunications system of claim 1, wherein the processor is configured to route the call if the one or more network parameters includes a domestic roaming identifier and if it is determined that a home network associated with a home network identifier is not available.

7. The telecommunications system of claim 1, wherein the processor is configured to route the call if the one or more network parameters includes an international roaming identifier and if it is determined that a home network associated with a home network identifier is not available.

8. A wireless communications device comprising:

a memory device configured to include an executable algorithm and a range of IMS proxy servers, wherein the range includes at least one home IMS proxy server address, at least one domestic IMS proxy server address, and at least one international IMS proxy server address using a proxy call session control function (P-CSCF), to configure a handheld device to communicate over a telecommunications network without accessing a carrier controlled network;

a processor coupled to the memory device, the processor configured to execute the executable algorithm that causes the processor to detect one or more network parameters of a data network that the communications device is connected to, detect a location of the communications device, and select a IMS proxy server from the range of IMS proxy servers, and route a call to the selected IMS proxy server based on the one or more data network parameters and the location;

wherein the processor is configured to route the call if the one or more network parameters includes a domestic roaming identifier and if it is determined that domestic roaming is available.

9. The wireless communications device of claim 8, wherein the processor is further configured to implement an encryption feature as a function of a wireline or wireless network type, an application type, and a location as a function of the handheld device location.

10. The wireless communications device of claim 8, wherein the processor is further configured to initiate a virtual private network tunnel as a function of the one or more network parameters after selection of a network P-CSCF.

11. The wireless communications device of claim 8, wherein the processor is further configured to implement encryption as a function of the one or more network parameters before selection of a network P-CSCF as a function of the handheld device location.

12. The wireless communications device of claim 8, wherein the processor is configured to route the call if the one or more network parameters includes a home network identifier and a proxy-call Session control function is selected and a determination is made by the handheld device that a communication session should be established with a P-CSCF associated with national roaming OTT server and international roaming OTT server based on the location of the handheld device.

13. The wireless communications device of claim 8, wherein the processor is configured to route the call if the one or more network parameters includes an international roaming identifier and if it is determined that international roaming is available.

14. A method of operating a wireless communications device comprising:

maintaining a range of IMS proxy servers, wherein the range includes at least one home IMS proxy server address, at least one domestic IMS proxy server address, and at least one international IMS proxy server address using a proxy call session control function (P-CSCF) and the range is maintained without accessing a carrier controlled network;

detecting one or more network parameters of a network that the communications device is connected to;

detecting a location of the communications device;

selecting an IMS proxy server from the range of IMS proxy servers; and

routing a call to the selected IMS proxy server based on the one or more network parameters and the location;

wherein routine the call to the selected IMS proxy server further comprises routine the call if the one or more network parameters includes an international network identifier and it is determined that a communication session should be established.

15. The method as recited in claim 14 wherein routing the call to the selected IMS proxy server further comprises routing the call to the selected IMS proxy server only if the one or more network parameters includes a home network identifier and it is determined that a communication session should be established.

16. The method as recited in claim 14 wherein routing the call to the selected IMS proxy server further comprises routing the call to the selected IMS proxy server only if the one or more network parameters includes a domestic network identifier and it is determined that a communication session should be established.

17. The method as recited in claim 14 further comprising implementing an encryption feature as a function of the one or more network parameters of a network type, an application type, and a location and it is determined that a communication session should be established.
