Abstract

A one-to-many wireless telephone communication system includes a transmitting telephone that transmits voice packets in, e.g., CDMA to a base station in an IP-based infrastructure. The base station converts the CDMA packets to IP and sends them through the infrastructure to a communication manager, which copies the packets as many times as necessary for the recipient telephones in the group and sends the IP packets back through the infrastructure using the IP addresses of the recipients. The base stations receiving the IP packets transform them to voice packets and transmit the voice packets to the recipient telephones, thereby relieving the telephones from having to support IP.

Claims

1. A one-to-many wireless telephone system, comprising:

at least one infrastructure component;

at least one wireless transmitting telephone using a wireless telephone over-the-air (OTA) protocol not encapsulated in an Internet protocol (IP) to communicate with the infrastructure component,

the infrastructure component transforming OTA information to IP information and sending the IP information through an infrastructure to a communication manager accessing a database of user groups, the communication manager sending copies of the IP information to recipient wireless telephones in a group of at least three telephones including the transmitting telephone;

the infrastructure component or another like infrastructure component transforming the IP information to OTA information and sending the OTA information to the recipient wireless telephones.

2. The system of claim 1, wherein the OTA protocol is a code division multiple access (CDMA) air interface protocol.

3. The system of claim 1, wherein the infrastructure component is a base station (BTS).

4. The system of claim 1, wherein the infrastructure component converts OTA protocol packets to IP packets.

5. The system of claim 1, wherein the infrastructure component converts IP packets to OTA protocol packets.

6. The system of claim 4, wherein the infrastructure component converts IP packets to OTA protocol packets.

7. A method for permitting one-to-many communication between at least a transmitting wireless telephone and at least two recipient wireless telephones, comprising:

sending voice packets unencapsulated in an IP-based protocol from the transmitting telephone to an infrastructure;

encapsulating the voice packets in at least one IP-based protocol at the infrastructure to render IP-based protocol packets;

sending at least two sets of the IP-based protocol packets through the infrastructure;

extracting voice packets from the sets of the IP-based protocol packets; and

transmitting the voice packets unencapsulated in an IP-based protocol to the recipient telephones.

8. The method of claim 7, wherein the voice packets are code division multiple access (CDMA) voice packets.

9. The method of claim 7, wherein the act of encapsulating is undertaken by a base station (BTS) in the infrastructure.

10. The method of claim 7, wherein the act of extracting is undertaken by a base station (BTS) in the infrastructure.

11. The method of claim 7, comprising copying the IP-based protocol packets.

12. The method of claim 11, wherein the act of copying is undertaken by a communication manager.

13. The method of claim 7, comprising establishing half duplex communication between the telephones.

15. The system of claim 14, wherein the OTA voice packets are code division multiple access (CDMA) packets.

16. The system of claim 14, further comprising an infrastructure transmitting packets between the IP endpoint and the communication manager.

17. The system of claim 14, wherein the IP endpoint is a base station (BTS).

18. The system of claim 14, wherein half duplex communication is established by the communication manager.

14. A telephone system for use in a one-to-many communication session, comprising:

at least one over-the-air (OTA) transmitting endpoint indicating a group of OTA recipient endpoints and generating OTA voice packets intended therefor;

at least one IP endpoint receiving the OTA voice packets and outputting IP-based protocol packets in response thereto; and

at least one communication manager receiving the IP-based protocol packets and duplicating them for the OTA recipient endpoints, the IP-based protocol packets being sent to at least one IP endpoint which receives the IP-based protocol packets and outputs OTA voice packets in response thereto for transmission thereof to the OTA recipient endpoints.
