Abstract

A communicator (110) that is transferable across different types of mobile devices (210) is disclosed. The communicator can simultaneously operate with both voice communication links (190) and data communication links (192), and with both voice and data information. The communicator may be transferred across various mobile devices, including but not limited to: mobile telephones (120), personal digital assistants (130), music players (170), radios, mobile computers (145), or devices that are a combination thereof. Some embodiments of the invention may be transferred while operating without breaking a wireless communication link. Data information may carried on a data link, such as a Bluetooth® link, a wireless Ethernet link, or an IEEE 802.11 link. Data information may also be carried on the voice link, such as a global system for mobile communication (GSM) link or a code division multiple access (CDMA) link. Similarly, voice information may be carried either on the voice link or on the data link, for example, voice over Internet protocol (IP).

Claims

1. A wireless communicator (110) adapted for use with an active host (210), the wireless communicator comprising:

a voice receiver (260) configured to receive an incoming voice radio signal (264) and to provide based thereon an incoming voice baseband signal (262);

a voice transmitter (270) configured to receive an outgoing voice baseband signal (272) and to transmit based thereon an outgoing voice radio signal (274);

a data receiver (260) configured to receive an incoming data radio signal (264) and to provide based thereon an incoming data baseband signal (262);

a data transmitter (270) configured to receive an outgoing data baseband signal (272) and to transmit based thereon an outgoing data radio signal (274); and

a baseband modem (230) configured to receive the incoming voice baseband signal and the incoming data baseband signal, to produce the outgoing voice baseband signal and the outgoing data baseband signal, to receive an outgoing host signal (214) from the active host, and to provide an incoming host signal (212) to the active host;

wherein the wireless communicator is adapted to be transferred across and to operate with at least two mobile host devices of different types, where at any one time one of the mobile host devices is the active host.

2. The wireless communicator of claim 1, wherein:

the baseband modem is further configured to operate in a mode selected from a mode that converts the incoming voice baseband signal to the incoming host signal, a mode that converts the incoming voice baseband signal to the outgoing data baseband signal, a mode that converts the incoming data baseband signal to the incoming host signal, a mode that converts the incoming data baseband signal to the outgoing voice baseband signal, a mode that converts the outgoing host signal to the outgoing voice baseband signal, a mode that converts the outgoing host signal to outgoing data baseband signal, and a mode that is a combination of at least two thereof; and

the wireless communicator further comprises a controller (250) configured to control the mode of the baseband modem.

3. The wireless communicator of claim 1, further comprising:

a controller (250) configured to initiate a communication link between the wireless communicator and an external device, the communication link being selected from a voice communication link (190), a data communication link (192), and a low-power communication link (194).

4. The wireless communicator of claim 3, wherein:

the controller is further configured to determine which communication links are currently available, to select a one of the available links and to initiate the communication link on the preferred link.

5. The wireless communicator of claim 3, wherein:

the controller is further configured to keep the communication link active while the wireless communicator is transferred from a first mobile host device being active to a different mobile host device being active.

6. The wireless communicator of claim 3, further comprising:

a nonvolatile memory (255);

wherein the controller is further configured to use data held in the nonvolatile memory to initiate the communication link.

7. The wireless communicator of claim 6, wherein the data used by the controller is selected from subscription data, user identification data, user preference data, security data, and a combination of at least two thereof.

8. The wireless communicator of claim 1, wherein the incoming voice radio signal and the outgoing voice radio signal are selected from mobile telephone signals, advanced mobile phone system (AMPS) signals;

global system for mobile communication (GSM) signals, time division multiple access (TDMA) signals, code division multiple access (CDMA) signals, and wideband code division multiple access (WCDMA) signals.

9. The wireless communicator of claim 1, wherein the incoming data radio signal and the outgoing data radio signal are selected from wireless local area network (WLAN) signals, wireless Ethernet signals, Institute of Electrical and Electronics Engineers (IEEE) standard 802.11 signals, low-power wireless signals, and Bluetooth signals.

10. The wireless communicator of claim 1, wherein the active mobile device is of a type selected from a mobile telephone (120), a personal digital assistant (130), a music player (170), a radio, a mobile computer (145), a notebook computer, a pocket computer, a tablet computer, and a device that is a combination of at least two thereof.

11. The wireless communicator of claim 1, further comprising:

a second data receiver (260) configured to receive a second incoming data radio signal and to provide to the baseband modem based thereon a second incoming data baseband signal;

a second data transmitter (270) configured to receive a second outgoing data baseband signal from the baseband modem and to transmit based thereon a second outgoing data radio signal; and

wherein the incoming data signal and the outgoing data signal are wireless local area network (WLAN) signals and the second incoming data signal and the second outgoing data signal are low-power wireless signals.

12. The wireless communicator of claim 1, wherein the baseband modem is further configured to provide to the voice transmitter data information that is formatted for transmission over a voice communication link (190), and to receive from the voice receiver data information that is formatted for transmission over the voice communication link.

13. The wireless communicator of claim 1, wherein the baseband modem is further configured to provide to the data transmitter voice information that is formatted for transmission over a data communication link (192), and to receive from the data receiver voice information that is formatted for transmission over the data communication link.

14. A wireless communicator adapted for use with an active host, the wireless communicator comprising:

means for receiving an incoming voice radio signal and for providing based thereon an incoming voice baseband signal;
