Abstract

Methods and systems for registering a phone device on a synthetic communication network are described. One implementation receives a request to connect the phone device to a synthetic communication network that transmits messages over a data network using one or more phone numbers from a voice network. A phone number and a country code associated with the phone device to be used for communications over the synthetic network are obtained. The phone number is normalized to a standard format distinguishing the resulting normalized phone number from international phone numbers using the synthetic network. Before the phone device is registered, an association between the normalized phone number and the phone device is verified by sending a verification message addressed to the phone device that loops back to the phone device. If the phone device confirms the verification as authentic, an authorization allows the phone device to communicate over the synthetic network.

Claims

1. A method, comprising:

receiving, in a multimedia client on a transmitting mobile device, a user selection of multimedia data, formatted in accordance with a first format, to be sent to a receiving mobile device;

uploading the selected multimedia data from the transmitting mobile device to a multimedia communication server;

receiving at the transmitting mobile device from the multimedia communication server a multimedia identifier associated with the multimedia data uploaded to the multimedia communication server; and

transmitting the multimedia identifier, over a synthetic communications network, from the transmitting mobile device to the receiving mobile device, the multimedia identifier usable by the receiving mobile device to request a download to the receiving mobile device of the multimedia data in a transcoded secondary format that the receiving mobile device can process, wherein the receiving mobile device is identified on the synthetic communications network by a phone number which, before transmission of the multimedia identifier, had been confirmed to be associated with the receiving mobile device and provisioned on a voice network as a result of receipt at the receiving mobile device of a verification message transmitted by the receiving mobile device and addressed to the phone number.

2. The method of claim 1, wherein the multimedia data is selected from a set of multimedia data types including images, videos, sound and combinations thereof.

3. The method of claim 1, further comprising the step of receiving at the transmitting mobile device from the multimedia server a message confirming receipt of the multimedia data by the receiving mobile device.

4. The method of claim 3, wherein the message confirming receipt of the multimedia data by the receiving mobile device is a thumbnail image derived from the multimedia data.

5. A method, comprising:

receiving, at a multimedia communication server from a transmitting mobile device on a synthetic communications network, multimedia data formatted in accordance with a first format;

storing, by the multimedia communications server, the multimedia data in the first format;

transmitting, from the multimedia communication server to the transmitting mobile device, a multimedia identifier associated with the multimedia data stored in the first format;

receiving from a receiving mobile device a request for the multimedia data, the request including the multimedia identifier; and

responsive to the received request, transmitting the multimedia data in a secondary format, transcoded from the first format, to the receiving mobile device, wherein the receiving mobile device is identified on the synthetic communications network by a phone number which, before transmission of the transcoded multimedia data, had been confirmed to be associated with the receiving mobile device and provisioned on a voice network as a result of receipt at the receiving mobile device of a verification message transmitted by the receiving mobile device and addressed to the phone number.

6. The method of claim 5, wherein the secondary format is identified in a profile of the receiving mobile device as a format preferred by a user of the receiving mobile device from among a plurality of secondary formats that are compatible with the receiving mobile device.

7. The method of claim 5, further comprising selecting the secondary format from a plurality of secondary formats that are compatible with the receiving mobile device, which selected format is more efficient for the transmission of the multimedia data on the synthetic network than at least one of the other of the plurality of secondary formats.

8. The method of claim 5, further comprising transmitting a download confirmation message to the transmitting mobile device responsive to the transmission of the transcoded multimedia data to the receiving mobile device.

9. The method of claim 8, wherein the download confirmation message includes a thumbnail image derived from the multimedia data.

10. The method of claim 6, wherein the multimedia data is selected from a set of multimedia data types including images, videos, sound and combinations thereof.

11. The method of claim 5, wherein the multimedia data is selected from a set of multimedia data types including images, videos, sound and combinations thereof.

12. A transmitting mobile device, comprising:

a processor that executes instructions; and

a multimedia client, executed by the processor, configured to;

receive a user selection of multimedia data, formatted in accordance with a first format, for transmission to a receiving mobile device;

upload the selected multimedia data, formatted in accordance with the first format, from the transmitting mobile device to a multimedia communication server;

receive a multimedia identifier associated with the multimedia data uploaded to the multimedia communication server; and

transmit the multimedia identifier over a synthetic communications network to the receiving mobile device, the multimedia identifier usable by the receiving mobile device to request the download to the receiving mobile device of the multimedia data transcoded into a secondary format that the receiving mobile device can process, wherein the receiving mobile device is identified on the synthetic communications network by the transmitting mobile device using a phone number for the receiving mobile device which, before transmission of the multimedia identifier, had been confirmed to be associated with the receiving mobile device and provisioned on a voice network as a result of receipt at the receiving mobile device of a verification message transmitted by the receiving mobile device and addressed to the phone number.

13. The transmitting mobile device of claim 12, wherein the first format and the secondary format are selected from a set of video formats including:

H.261, H.263, H.264, M-JPEG, MPEG-1, MPEG-2, MPEG-4, Ogg, Theora, VC-1 and derivatives and combinations of these formats.

14. The transmitting mobile device of claim 12, wherein the multimedia data is selected from a set of multimedia data types including images, videos, sound and combinations thereof.
