Abstract

Methods and systems are described for routing call in a wireless network environment. In one embodiment, a phone address is assigned to a subscriber and/or a subscriber'"'"'s mobile telecommunications device. A call directed to the phone address is routed to a call processing system. An outbound call from the call processing system is placed to a wireless communication service provider so as to cause, at least in part, the wireless communication service provider to route the outbound call to the subscriber'"'"'s mobile telecommunications device, wherein the call processing system configures call signaling parameters associated with the outbound call so that the outbound call appears to be to a phone number ported to the wireless communication service provider, and wherein the phone number has not been ported to the wireless communication service provider. The outbound call is bridged with the inbound call.

Claims

1. A method of routing calls:

receiving at a softswitch a first call intended for a user, the first call associated with a calling party phone address,

wherein the first call intended for the user is directed to a user phone address;

using signaling information associated with the first call to access account information for the user;

placing an outbound call from the softswitch to a wireless communications service provider associated with the user phone address, wherein the softswitch configures call signaling parameters so as to preserve the calling party phone address in the outbound call signaling information, and to cause, at least in part, the wireless communication service provider to route the outbound call to the user'"'"'s mobile telecommunications device;

causing, at least in part, one or more future calls from the user'"'"'s mobile telecommunications device to be presented to called parties with the user phone address;

receiving at the softswitch a second call intended for the user from a second calling party, the second call directed to the user phone address, wherein;

the second calling party is a member of a same wireless network as the user, and

optimal routing is disabled with respect to the second calling party, to thereby inhibit the second call from being routed directly to the user'"'"'s mobile telecommunications device without transit through the softswitch.

2. The method as defined in claim 1, wherein the user phone address is not assigned to the wireless communication service provider.

3. The method as defined in claim 1, wherein the user phone address has not been ported to the wireless communication service provider.

4. The method as defined in claim 1, wherein the user phone address is coded as NXXTYPE=51.

5. The method as defined in claim 1, wherein the user is a Mobile Virtual Network Operator (MVNO) subscriber.

6. The method as defined in claim 1, wherein a Mobile Virtual Network Operator (MVNO) allocates phone addresses, including the user address, for its mobile phones from an address pool, wherein calls to phone addresses in the address pool route through the Public Switched Telephone Network (PSTN) to an MVNO softswitch.

7. The method as defined in claim 1, wherein routing the outbound call to the wireless communication service provider comprises routing the outbound call to a mobile switching center associated with the wireless communication service provider via an SS7 ISUP (Signaling System 7 ISDN User Part) Initial Address Message.

8. The method as defined in claim 1, the method further comprising causing, at least in part:

setting of a Generic Address parameter to the user phone address;

setting of a Called Party Number parameter to a Location Routing Number of a wireless communication service provider gateway mobile switching center; and

setting of a Translated Called Number Indicator (TCNI) bit in a Forward Call Parameter.

9. The method as defined in claim 1, the method further comprising transmitting over a data network to a user terminal information regarding the first call while the outbound call to the wireless communication service provider is in progress.

10. The method as defined in claim 1, the method further comprising:

determining whether a telecommunications client application associated with the user is online;

if the telecommunications client application is online, transmitting over a data network information regarding the first call; and

receiving a handling instruction from the user via the telecommunications client application regarding the first call.

11. The method as defined in claim 1, wherein a text message addressed to the user phone address routes to the wireless communication service provider for transmittal to the user'"'"'s mobile telecommunications device.

12. The method as defined in claim 11, wherein a Mobile Virtual Network Operator (MVNO) arranges to have an inter-carrier Short Message Service (SMS) gateway broadcast MVNO number blocks, including the user phone address, to other inter-carrier SMS gateway providers.

13. The method as defined in claim 1, wherein the calling party phone address is presented on a mobile device associated with the user so the user can screen the first call.

15. The method as defined in claim 1, wherein the user is a Mobile Virtual Network Operator (MVNO) subscriber.

16. The method as defined in claim 1, wherein a Mobile Virtual Network Operator (MVNO) allocates phone addresses, including the user address, for its mobile phones from an address pool, wherein calls to phone addresses in the address pool route through the Public Switched Telephone Network (PSTN) to an MVNO softswitch.

17. The method as defined in claim 1, the method further comprising causing, at least in part:

setting of a Generic Address parameter to the user phone address;

setting of a Called Party Number parameter to a Location Routing Number of a wireless communication service provider gateway mobile switching center; and

setting of a Translated Called Number Indicator (TCNI) bit in a Forward Call Parameter.

18. The method as defined in claim 1, wherein a text message addressed to the user phone address routes to the wireless communication service provider for transmittal to the user'"'"'s mobile telecommunications device.

19. The method as defined in claim 11, wherein a Mobile Virtual Network Operator (MVNO) arranges to have an inter-carrier Short Message Service (SMS) gateway broadcast MVNO number blocks, including the user phone address, to other inter-carrier SMS gateway providers.

14. A method of routing calls, the method comprising:

receiving at a softswitch a first call intended for a user from a first calling party, the first call directed to a first phone address and the first call is associated with a calling phone address,

using signaling information associated with the first call to access account information for the user;

placing a first outbound call from the softswitch to a wireless communications service provider wherein the softswitch configures call signaling parameters associated with the first outbound call so as to preserve the calling party phone address and to cause, at least in part, the wireless communication service provider to route the first outbound call to the user'"'"'s mobile telecommunications device; and

causing, at least in part, one or more future calls from the user'"'"'s mobile device to be presented to called parties with the first phone address, wherein the first phone address is other than a phone address used by the softswitch to route the outbound call to the user'"'"'s mobile telecommunication device; and

receiving at the softswitch a second call intended for the user from a second calling party, the second call directed to the first phone address, wherein;

the second calling party is a member of a same wireless network as the user, and

optimal routing is disabled with respect to the second calling party, to thereby inhibit the second call from being routed directly to the user'"'"'s mobile telecommunications device without transit through the softswitch.

20. A system comprising:

at least one computing device;

program instructions stored in non-transitory memory, that when executed by the at least one computing device, are configured to cause the system to perform operations comprising;

receiving a first call intended for a user, the first call associated with a calling party phone address,

wherein the first call intended for the user is directed to a user phone address;

using signaling information associated with the first call to access account information for the user;

placing an outbound call to a wireless communications service provider associated with the user phone address, wherein call signaling parameters are configured so as to preserve the calling party phone address in the outbound call signaling information, and to cause, at least in part, the wireless communication service provider to route the outbound call to the user'"'"'s mobile telecommunications device;

causing, at least in part, one or more future calls from the user'"'"'s mobile telecommunications device to be presented to called parties with the user phone address;

receiving a second call intended for the user from a second calling party, the second call directed to the user phone address, wherein;

the second calling party is a member of a same wireless network as the user, and

optimal routing is disabled with respect to the second calling party, to thereby inhibit the second call from being routed directly to the user'"'"'s mobile telecommunications device without transit through the system.

21. The system as defined in claim 20, wherein the user phone address is not assigned to the wireless communication service provider.

22. The system as defined in claim 20, wherein the user phone address has not been ported to the wireless communication service provider.
