Abstract

A database stores unique associations between account identifiers and mobile-network telephone numbers assigned by a mobile network to mobile communications devices. The account identifiers are also associated with voice-over-IP (VoIP) telephone numbers. Voice calls between the mobile communications devices are made as voice-over-IP (VoIP) calls using respective VoIP telephone numbers. Tracking of the VoIP calls is performed through the mobile network using respective mobile-network telephone numbers, so that a prepaid balance can be enforced.

Claims

1. An electronic communications system comprising:

a mobile network for providing mobile communication between a plurality of mobile communications devices based on mobile-network telephone numbers associated with plurality of the mobile communications devices, the mobile network supporting at least one mobile-network protocol and an Internet Protocol (IP);

a wireless local-area network (WLAN) for providing WLAN communication between the plurality of mobile communications devices and a wide-area IP network, the WLAN operating on at least the Internet Protocol; and

a communications routing system coupled to the mobile network and coupled to the WLAN via the wide-area IP network, the communications routing system operating on the Internet Protocol, the communications routing system comprising;

at least one database storing a plurality of unique associations between account identifiers and the mobile-network telephone numbers, and further between the account identifiers and voice-over-IP (VoIP) telephone numbers; and

a routing engine responsive to incoming communications events including initiation of voice calls, ending of voice calls, and communication of short message service (SMS) messages, the routing engine configured to initiate and end voice calls between the plurality of mobile communications devices as voice-over-IP (VoIP) calls using respective VoIP telephone numbers, the routing engine further configured to track VoIP calls made through the mobile network using respective mobile-network telephone numbers.

2. The system of claim 1, wherein the routing engine is configured to control VoIP calls made with the VoIP telephone numbers based on usage data received from the mobile network for respective mobile-network telephone numbers.

3. The system of claim 2, wherein the communications routing system further stores balance data in association with the account identifiers, the balance data representative of prepaid call time, and wherein the routing engine is configured to update the balance data based on the usage data received from the mobile network.

4. The system of claim 3, wherein the routing engine is configured to deny initiation of a VoIP call requested by a particular mobile communications device associated with a depleted balance when the particular mobile communications device is only connected to the mobile network, and the routing engine configured to allow a VoIP call requested by the particular mobile communications device associated with the depleted balance when the particular mobile communications device is connected to the WLAN.

5. The system of claim 1, wherein the routing engine is configured to trigger a push notification in response to receiving a communications event for initiation of a VoIP call to a destination mobile communications device of the plurality of mobile communications devices, the push notification configured to trigger Session Initiation Protocol (SIP) client registration by the destination mobile communications device.

6. The system of claim 1, further comprising a proxy coupled to the wide-area IP network, the proxy configured to handle VoIP call handoffs between the mobile network and the WLAN.

7. The system of claim 1, further comprising a proxy coupled to the wide-area IP network, the proxy configured to prioritize communications events associated with an enhanced 911 system.

12. The system of claim 1, wherein the routing engine is configured to trigger a push notification in response to receiving a communications event for initiation of a VoIP call to a destination mobile communications device of the plurality of mobile communications devices, the push notification configured to trigger Session Initiation Protocol (SIP) client registration by the destination mobile communications device.

8. A communications routing system coupled to a mobile network and coupled to a wireless local-area network (WLAN) via a wide-area Internet Protocol (IP) network, the communications routing system comprising:

at least one database storing a plurality of unique associations between account identifiers and mobile-network telephone numbers assigned by the mobile network to a plurality of mobile communications devices, and further between the account identifiers and voice-over-IP (VoIP) telephone numbers; and

a routing engine responsive to incoming communications events including initiation of voice calls, ending of voice calls, and communication of short message service (SMS) messages, the routing engine configured to initiate and end voice calls between the plurality of mobile communications devices as voice-over-IP (VoIP) calls using respective VoIP telephone numbers, the routing engine further configured to track VoIP calls made through the mobile network using respective mobile-network telephone numbers.

9. The system of claim 8, wherein the routing engine is configured to control VoIP calls made with the VoIP telephone numbers based on usage data received from the mobile network for respective mobile-network telephone numbers.

10. The system of claim 9, wherein the communications routing system further stores balance data in association with the account identifiers, the balance data representative of prepaid call time, and wherein the routing engine is configured to update the balance data based on the usage data received from the mobile network.

11. The system of claim 10, wherein the routing engine is configured to deny initiation of a VoIP call requested by a particular mobile communications device associated with a depleted balance when the particular mobile communications device is only connected to the mobile network, and the routing engine configured to allow a VoIP call requested by the particular mobile communications device associated with the depleted balance when the particular mobile communications device is connected to the WLAN.

13. A method for electronic communications comprising:

storing in at least one database a plurality of unique associations between account identifiers and mobile-network telephone numbers assigned by a mobile network to a plurality of mobile communications devices, and further between the account identifiers and voice-over-IP (VoIP) telephone numbers;

initiating and ending voice calls between the plurality of mobile communications devices as voice-over-IP (VoIP) calls using respective VoIP telephone numbers; and

tracking VoIP calls made through the mobile network using respective mobile-network telephone numbers.

14. The method of claim 13, further comprising controlling VoIP calls made with the VoIP telephone numbers based on usage data received from the mobile network for respective mobile-network telephone numbers.

15. The method of claim 14, further comprising storing balance data in association with the account identifiers, the balance data representative of prepaid call time, and updating the balance data based on the usage data received from the mobile network.

16. The method of claim 15, denying initiation of a VoIP call requested by a particular mobile communications device associated with a depleted balance when the particular mobile communications device is only connected to the mobile network, and allowing a VoIP call requested by the particular mobile communications device associated with the depleted balance when the particular mobile communications device is connected to a wireless local-area network (WLAN).

17. The method of claim 13, triggering a push notification in response to receiving a communications event for initiation of a VoIP call to a destination mobile communications device of the plurality of mobile communications devices, the push notification configured to trigger Session Initiation Protocol (SIP) client registration by the destination mobile communications device.
