Abstract

An embodiment of a method for initiating an outgoing call from a cellular handset to a fixed network using a DECT base station includes receiving an outgoing call request from a cellular handset by an adaptor module in communication with the cellular handset. The outgoing call request includes a request to establish a call session with a communication device over a fixed network. The method further includes sending a call set-up message to a DECT base station in response to receiving the outgoing call request. The DECT base station is configured to initiate an outgoing call to the communication device over the fixed network in response receiving the call set-up message. The method further includes receiving a call connect message from the DECT base station, and establishing a call session between the cellular handset and the communication device.

Claims

1. A method for initiating an outgoing call from a cellular handset to a fixed network using a DECT base station comprising:

receiving an outgoing call request in cellular handset voice data format from a cellular handset by a removable adaptor module in communication with the cellular handset, said removable adaptor module removably coupled externally to a data port of the cellular handset, the outgoing call request including a request to establish a call session with a communication device over a fixed network;

converting, at the removable adaptor module, the cellular handset voice data to DECT voice data;

sending a call set-up message in DECT voice data format to a DECT base station in response to receiving the outgoing call request, the DECT base station configured to initiate an outgoing call to the communication device over the fixed network in response receiving the call set-up message;

receiving a call connect message from the DECT base station; and

establishing a call session between the cellular handset and the communication device.

2. The method of claim 1, wherein the sending of the call set-up message to the DECT base station includes sending the call-setup message over a DECT air interface.

3. The method of claim 1 further comprising:

receiving DECT voice data associated with the call session from the DECT base station;

converting the DECT voice data to cellular handset voice data; and

sending the cellular handset voice data to the cellular handset.

4. The method of claim 1, wherein the adaptor module is configured to be interchangeably coupled to a data port of a second cellular handset.

5. The method of claim 1, wherein the fixed network comprises at least one of a PSTN and an IP network.

6. A method for receiving an incoming call from a fixed network by a cellular handset using a DECT base station comprising:

receiving a call set-up message in DECT voice data format from a DECT base station by a removable adaptor module, the removable adaptor module removably coupled externally to a data port of the cellular handset, the call set-up message associated with an incoming call from a communication device over a fixed network;

converting, at the removable adaptor module, the DECT voice data to cellular handset data;

sending an incoming call request in cellular handset data format to a cellular handset in communication with the removable adaptor module, the incoming call request including a request to establish a call session with the communication device;

receiving an incoming call acknowledgement from the cellular handset;

sending a call connect message to the DECT base station; and

establishing a call session between the cellular handset and the communication device.

7. The method of claim 6 further comprising, wherein the sending of the call connect message to the DECT base station includes sending the call connect message over a DECT air interface.

8. The method of claim 6 further comprising:

receiving cellular handset voice data from the cellular handset;

converting the cellular handset voice data to DECT voice data; and

sending the DECT voice data to the DECT base station.

9. The method of claim 6, wherein the adaptor module is configured to be interchangeably coupled to a data port of a second cellular handset.

10. The method of claim 6, wherein the fixed network comprises a PSTN.

11. The method of claim 6, wherein the fixed network comprises an IP network.

12. A standalone cellular to DECT adaptor module comprising:

a data interface configured to be externally coupled to a data port of a cellular handset;

a DECT transceiver; and

at least one processor configured to;

establish a call session between a cellular handset and a communication device over a fixed network;

receive DECT voice data associated with the call session from a DECT base station via the DECT transceiver, the DECT base station in communication with the fixed network;

convert the DECT voice data to cellular voice data;

send the cellular voice data to the cellular handset via the data interface; and

receive cellular voice data associated with the call session from the cellular handset via the data interface;

convert the cellular voice data to DECT voice data;

send the DECT voice data to the DECT base station via the DECT transceiver.

13. The standalone cellular to DECT adaptor module of claim 12, wherein the data port is a USB port.

14. The standalone cellular to DECT adaptor module of claim 12, wherein the data port is a mini-SD port.

15. The standalone cellular to DECT adaptor module of claim 12, wherein the at least one processor is further configured to:

receive an outgoing call request from the cellular handset, the outgoing call request including a request to establish a call session with a communication device over a fixed network;

send a call set-up message to the DECT base station in response to receiving the outgoing call request, the DECT base station configured to initiate an outgoing call to the communication device over the fixed network in response receiving the call set-up message; and

receive a call connect message from the DECT base station.

16. The standalone cellular to DECT adaptor module of claim 12, wherein the at least one processor is further configured to:

receive a call set-up message from the DECT base station, the call set-up message associated with an incoming call from the communication device over the fixed network;

send an incoming call request to the cellular handset in communication, the incoming call request including a request to establish the call session with the communication device;

receive an incoming call acknowledgement from the cellular handset; and

send a call connect message to the DECT base station.

17. The standalone cellular to DECT adaptor module of claim 12, wherein the fixed network comprises at least one of a PSTN and an IP network.
