Abstract

Extending dual-mode phones using SMS messages. When operating in cellular mode, SMS messages originated by a mobility controller in the enterprise command features such as indicators on the dual-mode phone. SMS messages are received by an agent in the dual-mode phone. A mobility controller connected to the enterprise SIP PBX and voicemail system receives messages for example indicating voicemail status and sends specially formatted SMS messages to the cellular phone to operate indicators. Similarly, the dual-mode phone issues SMS messages to the enterprise mobility controller to request the enterprise PBX perform features such as call conferencing, call pickup, and call pull.

Claims

1. A method of extending capabilities of a dual-mode phone connected over a cellular network to a PBX comprising:

sending SMS messages between a dual-mode phone attached to the cellular network and a mobility controller connected to a PBX, and acting on the contents of the SMS message.

2. The method of claim 1 where the SMS message is authenticated prior to being acted upon.

3. The method of claim 2 where the SMS message is authenticated through the contents of the SMS message.

4. The method of claim 2 where the SMS message is authenticated by comparing the sender of the SMS message to a list of one or more authorized senders.

5. The method of claim 1 where the SMS message is generated by the mobility controller and sent through the PBX to the dual-mode phone over the cellular network which acts upon the contents of the SMS message.

6. The method of claim 1 where the SMS message is generated by the dual-mode phone and sent through the cellular network to the PBX and to the mobility controller which acts upon the contents of the SMS message.

7. The method of claim 5 where the SMS message is removed from the message queue on the dual-mode phone prior to being displayed to the user.

8. The method of claim 5 where the SMS message acts to operate an indicator on the dual-mode phone.

9. The method of claim 8 further comprising:

generating, at the mobility controller controller, a SMS message to operate an indicator on the dual-mode phone,

sending the SMS message through the cellular network to the dual-mode phone,

receiving, on dual-mode phone, the SMS message,

recognizing the SMS message on the dual-mode phone, and

operating the desired indicator on the dual-mode phone.

10. The method of claim 6 where the SMS message to the mobility controller causes the mobility controller to instruct the PBX to begin call conferencing with the target number contained in the SMS message.

11. The method of Claim 10 further comprising generating a SMS message by the mobility controller and sent through the PBX to the dual-mode phone over the cellular network confirming the conferencing operation.

12. The method of claim 6 where the SMS message to the mobility controller causes the mobility controller to instruct the PBX to begin call pickup.

13. The method of claim 6 where the SMS message to the mobility controller causes the mobility controller to instruct the PBX to begin call pull.

14. The method of claim 6 where the SMS message to the mobility controller causes the mobility controller to instruct the PBX to begin call transfer to a target number contained in the SMS message.

15. The method of claim 14 where the target number is authenticated prior to initiating call transfer.

16. The method of claim 14 further comprising generating a SMS message by the mobility controller and sent through the PBX to the dual-mode phone over the cellular network confirming the transfer.
