Abstract

A method, apparatus and computer program product is provided for verifying an association between a phone number provisioned by a voice network and a phone device. The verification is useful on a synthetic communication network that reuses the phone number to transmit text and other media types over a data network such as the Internet between phone devices registered on the synthesized network. One implementation receives a request to add a phone device previously registered with a voice network to the synthesized communication network. With respect to the synthesized network, the phone number is presumed to be unconfirmed even though it may have been previously provisioned from the voice network. Implementations of the invention attempt to transmit a verification message addressed to the phone device through a data channel within the voice network. If the phone number is in fact associated with the phone device then the verification message returns back to the phone device over the data channel on the voice network. If the verification message is received by the phone device, the phone number is confirmed as associated with the phone device. Once the phone number is confirmed, the synthetic network authorizes communication between the phone device and other phone devices registered on the synthetic communication network.

Claims

1. A processor implemented method for configuring a phone device for use on a synthetic communication network, comprising:

receiving a request to add a phone device to a synthetic communication network;

obtaining an unconfirmed phone number associated with the request;

transmitting a verification message from the phone device through a data channel within a voice network, the message addressed for delivery to the unconfirmed phone number;

receiving the verification message by the phone device through the data channel within the voice network, the verification message confirming the unconfirmed phone number;

responsive to receiving the verification message, authorizing the phone device to communicate data over the synthetic communication network using the confirmed phone number;

identifying a plurality of phone numbers in a directory stored on the phone device, each of the identified phone numbers corresponding to both a provisioned telephone number on the voice network and to a phone device authorized to communicate data over the synthetic communication network; and

synchronizing the identified phone numbers with corresponding entries in a synthetic communication client on the phone device.

2. The method of claim 1 further comprising transmitting a text message from the phone device and one of the synchronized phone numbers.

3. The method of claim 1 wherein the synthetic communication network may be used to transmit text messages combined with at least one other multimedia data type selected from a set of multimedia data types-including images, video, voice, music and data files.

4. The method of claim 1 wherein the phone device is selected from a set of devices having a phone number including:

a wireless phone, a wireless tablet computer, —

a wireless laptop and a wireless modern device.

5. The method of claim 1 wherein the verification message includes a randomly generated value having a predetermined number of digits.

6. The method of claim 1 wherein the data channel within the voice network provides compatibility with at least one protocol selected from a set of protocols including a short messaging system (SMS) and a multimedia Messaging service (MMS).

7. The method of claim 1 wherein the voice network uses a compatible protocol selected from a set of protocols including:

Global System for Mobile (GSM), Code Division Multiple Access (CDMA).

8. The method of claim 1 wherein the data network is associated with the voice network and is compatible with at least one protocol selected from a set of protocols including:

Enhanced Data Rates for GSM Evolution (EDGE), Universal Mobile Telephone Standard (UMTS), High Speed Downlink Packet Access (HSDPA) and Evolution Data Optimized (EVDO).

9. The method of claim 1 wherein the verification message on the phone device incorporates a randomly generated value with 4 predetermined number of digits that distinguishes the verification message from other Messages the phone device may receive.

10. The method of claim 1 farther comprising:

normalizing the unconfirmed phone number to maintain compatibility with an international telephone number standard and the voice network.

11. The method of claim 1 wherein the unconfirmed phone number is obtained from a user of the phone device.

12. The method of claim 1 wherein the unconfirmed phone number is obtained automatically from firmware on the phone device.

13. A non-transitory computer-readable medium operational on a processor for configuring a phone device on a synthetic communication network, having instructions, which when executed by the processor will cause the processor to:

in response to receiving a request to add a phone device to a synthetic communication network, obtain an unconfirmed phone number associated with the request;

transmit a verification message from the phone device through a data channel within a voice network, the message addressed for delivery to the unconfirmed phone number;

receive the verification message by the phone device through the data channel within the voice network, the verification message confirming the unconfirmed phone number;

responsive to receiving the verification message, authorize the phone device to communicate data over the synthetic communication network using the confirmed phone number;

identify a plurality of phone numbers in a directory stored on the phone device, each of the identified phone numbers corresponding to both a provisioned telephone number on the voice network and to a phone device authorized to communicate data over the synthetic communication network; and

synchronize the identified phone numbers with corresponding entries in a synthetic communication client on the phone device.

14. The non-transitory computer-readable medium of claim 13 wherein the phone device is selected from a set of devices having a phone number including:

a wireless phone, a wireless tablet computer, a wireless laptop and a wireless modem device.

15. The non-transitory computer-readable medium of claim 13 wherein the data channel of the voice network provides compatibility with at least one protocol selected from a set of protocols including a short messaging system (SMS) and a multimedia messaging service (MMS).

16. The non-transitory computer-readable medium of claim 13 wherein the preexisting voice network uses a compatible protocol selected from a set of protocols including:

Global System for Mobile (GSM) and Code Division Multiple Access (CDMA).

17. The non-transitory computer-readable medium of claim 13 wherein the voice network includes access to the Internet with at least one protocol selected from a set of protocols including:

Enhanced Data Rates from GSM Evolution (EDGE), Universal Mobile Telephone Standard (UMTS), High Speed Downlink Packet Access (FISDPA) and Evolution Data Optimized (ENDO).
