Abstract

In one aspect, a user terminal is configured to access an IMS network, and to obtain from the network an indication of a current dial-tone condition of the terminal. The terminal displays a graphical user-interface, GUI, that includes a visual indication of the current dial-tone condition of the terminal. In another aspect Application Server function in an IMS network is configured to provide information to a user terminal regarding a current dial-tone condition such that the user terminal is able to display an indication of the current dial-tone also known as call progress tone. Examples given in the application are dial-tone aka ring-back tone, message waiting tone and tones indicating that the user has activated call forwarding unconditional or call diversion. In another aspect a method of enabling a user of a user terminal accessing an IMS network to be informed of a current dial-tone condition of the user terminal includes: providing the user terminal with information regarding the current dial-tone condition; and, based on the obtained information, displaying the current dial-tone condition on a graphical user-interface on the user terminal.

Claims

1. A user terminal configured to access an IMS network, to obtain from the network an indication of a current dial-tone condition of the terminal, wherein said current dial-tone condition is one of a set of dial-tone conditions that includes a special condition dial-tone indicating an active CDIV, Communication Forward Unconditional, CFU, condition, and to display a graphical user-interface, GUI, that includes a visual indication of the current dial-tone condition of the terminal.

2. The user terminal of claim 1, wherein the set of dial tone conditions also includes a standard dial-tone, and a message-waiting dial-tone.

3. The user terminal of claim 1, wherein the dial-tone condition displayed is determined from dial-tone information provided in a Public Switched Telephone System, PSTN, Emulation Subsystem, PES, format.

4. The user terminal of claim 3, wherein the dial-tone information is provided to the user from an application server, AS.

5. The user terminal of claim 4 configured to obtain the dial-tone information from the AS when the user registers with the IMS or when the user creates, or activates a Communication Diversion, CDIV, Communication Forward Unconditional, CFU rule.

6. The user terminal of claim 1 configured as a Ut client, and operable to send a request to the network to obtain the indication of the current dial-tone condition of the terminal.

7. An Application Server, AS, function in an IMS network configured to provide information to a user terminal accessing the IMS network regarding a current dial-tone condition of the user in response to user registration with the IMS network, in response to creation or activation of a Communication Diversion, CDIV, Communication Forward Unconditional, CFU rule by the user, and in response to deactivation of a CDIV CFU rule by the user, such that the user terminal is able to display an indication of the current dial-tone.

10. The application server of claim 7 configured to determine the dial-tone condition of the user terminal by use of a Public Switched Telephone System, PSTN, Emulation Subsystem, PES.

8-9. -9. (canceled)

11. A method of enabling a user of a user terminal accessing an IMS network to be informed of a current dial-tone condition of the user equipment terminal, the method comprising:

determining the current dial-tone condition for the user from a set of dial-tone conditions that includes a special dial-tone indicating an active Communication Diversion, CDIV, Communication Forward Unconditional, CFU, condition;

providing the user terminal with information regarding the current dial-tone condition; and

based on the provided information displaying the current dial-tone condition on a graphical user-interface on the user terminal.

12. The method of claim 11 wherein the dial-tone condition information is provided in a Public Switched Telephone System, PSTN, Emulation Subsystem, PES, format.

13. The method of claim 11, wherein the dial-tone information is provided to the user from an application server, AS.

14. The method of claim 13 wherein the current dial-tone condition information is provided to the user terminal in response to user registration with the IMS network, or in response to creation or activation of a Communication Diversion, CDIV, Communication Forward Unconditional, CFU rule by the user.

15. The method of claim 14 further comprising providing an indication that the current dial-tone condition is normal in response to de-activation of a CDIV CFU rule by the user.

16. The method of claim 11 wherein the set of dial tone conditions also includes one or more of:

a standard dial-tone, and a message-waiting dial-tone.
