Abstract

Providing a single number presentation to the party called by a dual-mode phone. The operation of the cellular side of a dual-mode phone is altered such that when the user attempts to place an outgoing call using the cellular phone, the call is redirected to a preprogrammed incoming phone number associated with the enterprise. When the enterprise PBX answers this call, the dual-mode phone transmits the desired number to the enterprise PBX. The enterprise PBX then places the call to the desired number, and in the process transmits the caller-id information assigned to the dual-mode phone.

Claims

1. A method of operating a dual-mode phone comprising:

detecting an attempt to place a call through a cellular connection to a target number;

storing the target number;

initiating a cellular connection to a predetermined number in lieu of the target number, the predetermined number being different than the target number and assigned to a private branch exchange that is part of a wireless network; and

once connected, transmitting the stored target number to a controller that is adapted to (i) receive the target number, (ii) identify the calling dual-mode phone, (iii) retrieve caller-id information associated with the dual-mode phone, (iv) call the target number and supply the caller-id information associated with the dual-mode phone, and (v) establish an audio connection between the dual-mode phone and the device associated with the target number.

2. The method of claim 1 wherein the transmitting of the stored target number includes encoding digits comprising the stored target number.

3. The method of claim 2 wherein the encoding of the digits comprising the stored target number comprises adding framing.

4. The method of claim 2 wherein the encoding of the digits comprising the stored target number comprises adding check digits.

5. The method of claim 1 wherein prior to initiating of the cellular connection, the method further comprises determining if the target number is a specific number and initiating a cellular connection using the target number if the target number is identical to the specific number.

6. The method of claim 5 wherein the specific number is a telephone number for emergency services.

7. The method of claim 5 wherein the specific number is a telephone number for information services.

8. The method of claim 2 wherein the encoding of the digits comprising the stored target number comprises adding authentication.

9. The method of claim 2 wherein the encoding of the digits comprising the stored target number comprises repeating digits.

10. The method of claim 1 wherein the transmitting of the stored target number is repeated a preset number of times.

11. The method of claim 1 wherein the transmitting of the stored target number is repeated for a preset period of time.

12. The method of claim 1 wherein the controller identifying the calling dual-mode phone comprises:

retrieving the caller-id information associated with the incoming call from the dual-mode phone, and

comparing the caller-id information against a list of authorized numbers.

13. A method of operating a dual-mode phone that includes a first radio subsystem for wireless fidelity (Wi-Fi) communications and a second radio subsystem for cellular communications, comprising:

initiating a call from the first radio subsystem to a wireless network controller and a mobility controller when the dual-mode phone is in range to receive communications from the wireless network controller so that the mobility controller processes information within the call and provides a network caller identification associated with the dual-mode phone to a called party;

detecting an attempt to place the call through a cellular connection to a target number;

storing the target number;

initiating a cellular connection to a predetermined number assigned to a device being part of the wireless network including the wireless network controller and the mobility controller in lieu of the target number, the predetermined number being different than the target number; and

once connected, transmitting the stored target number to the mobility controller that is adapted to (i) receive the target number and caller identification information associated with the dual-mode phone, (ii) identify a calling party as the dual-mode phone, and thereafter, (iii) establish a call to the target number over the wireless network while supplying the network caller identification associated with the dual-mode phone to the called party.

14. The method of claim 13 wherein the detecting of the attempt to place the call through the cellular connection comprises:

determining if the target number is a specific number; and

initiating a cellular connection using the target number if the target number is identical to the specific number.

15. The method of claim 14 wherein the specific number is a telephone number for emergency services.

16. The method of claim 14 wherein the specific number is a telephone number for information services.

17. A dual-mode phone comprising:

a first radio subsystem adapted to initiate a telephone call to a called party over a wireless fidelity (Wi-Fi) network;

a second radio subsystem adapted to initiate a call over a cellular network, where

in response to an attempt to place the call using the cellular network, the dual-mode phone (i) stores a phone number being a destination for the call, (ii) initiates a call to a predetermined number assigned to a device forming part of the Wi-Fi network in lieu of initiating the call over the cellular network, (iii) and providing the stored phone number and a caller-id information of the dual-mode phone so that a telephone call to the destination including a network caller-id information that corresponds to the caller-id information is initiated after the calling party is authenticated using the caller-id information.

18. The method of claim 17 wherein the caller-id information for the dual-mode phone being a cellular telephone number for the dual-mode phone.

19. The method of claim 17 wherein the network caller-id information is different than the caller-id information.

20. The method of claim 17 wherein the second radio subsystem is further adapted to detect an attempt to place a call to a phone number assigned for emergency services over the cellular network, and initiating a cellular connection using the phone number assigned for emergency services in lieu of routing the call to the Wi-Fi network.

21. The method of claim 17 wherein the second radio subsystem is further adapted to detect an attempt to place a call to a phone number assigned for information services over the cellular network, and initiating a cellular connection using the phone number assigned for information services in lieu of routing the call to the Wi-Fi network.
