Abstract

A system and method embeds text in a multicast transmission. An exemplary method comprises receiving non-voice data. The non-voice data is embedded within digitized voice data. The digitized voice data with the embedded non-voice data is wirelessly transmitted, by a computing device, as a multicast transmission to a plurality of mobile devices.

Claims

1. A method, comprising:

receiving, by a server, voice data from a mobile unit of a user using a VOIP call;

retrieving , by the server, non-voice data relating to the user from a database;

embedding , by the server, the non-voice data relating to the user within digitized voice data; and

wirelessly transmitting, by a computing device, the digitized voice data with the embedded non-voice data as a multicast transmission to a plurality of mobile devices.

2. The method of claim 1, wherein the computing device transmits one of directly to the plurality of mobile devices and indirectly to the plurality of mobile devices through a network.

3. The method of claim 2, wherein, when the computing device transmits directly, the plurality of mobile devices are disposed in a first operating area of the computing device.

4. The method of claim 2, wherein, when the computing device transmits indirectly, the plurality of mobile devices are disposed in a second operating area of the network.

5. The method of claim 1, wherein the computing device and the plurality of mobile devices operate on a common channel.

6. The method of claim 1, wherein the non-voice data includes at least one of identification data, location data, and command data.

7. A computing device, comprising:

a receiver on a server for receiving voice data from a mobile unit of a user using a VOIP call;

a database storing non-voice data relating to the user;

an embedder on the server for embedding the non-voice data relating to the user retrieved by the server within digitized voice data; and

a transmitter wirelessly transmitting the digitized voice data with the embedded non-voice data as a multicast transmission to a plurality of mobile devices.

8. The computing device of claim 7, wherein the receiver receives the non-voice data from one of a memory of the computing device, an audio input of the computing device, and a database of the server.

9. The computing device of claim 7, wherein the transmitter transmits one of directly to the plurality of mobile devices and indirectly to the plurality of mobile devices through a communication network.

10. The computing device of claim 9, wherein, when the computing device transmits directly, the plurality of mobile devices are disposed in a first operating area of the computing device.

11. The computing device of claim 9, wherein, when the computing device transmits indirectly, the plurality of mobile devices are disposed in a second operating area of the network.

12. A method, comprising:

receiving , by a server, voice data from a mobile unit of a user using a VOIP call;

retrieving , by a server, non-voice data relating to the user from a database;

embedding, by a computing device, non-voice data relating to the user within digitized voice data;

wirelessly transmitting the digitized voice data with the embedded non-voice data as a multicast transmission;

wirelessly receiving, by a plurality of mobile devices, the multicast transmission;

extracting, by each mobile device, the non-voice data from the digitized voice data;

executing, by each mobile device, a function corresponding to a type of the non-voice data; and

playing, by each mobile device, the voice data.

13. A system, comprising:

a computing device including a receiver receiving voice data from a mobile unit of a user using a VOIP call, a database storing non-voice data relating to the user, an embedder on a server for embedding the non-voice data relating to the user retrieved by the server within digitized voice data, and a transmitter wirelessly transmitting the digitized voice data with the embedded non-voice data as a multicast transmission; and

a plurality of mobile devices, each of the mobile devices including a receiver wirelessly receiving the multicast transmission, an extractor extracting the non-voice data from the digitized voice data, a processor executing a function corresponding to a type of the non-voice data, and an audio output playing the voice data.
