Method and system for triggering activation of IMS applications on a mobile radio terminal

1. A method of remotely activating a non-native IP multimedia subsystem (IMS) application of an electronic device, comprising:

receiving at least one of a general IMS availability registration from the electronic device or a native IMS application registration from the electronic device;

responding to the general IMS availability registration or the native IMS application registration by checking a database that associates IMS applications with the electronic device from which the registration was received and identifying a non-native IMS application corresponding to the electronic device from which the registration was received for remote activation;

transmitting an activation trigger for the identified non-native IMS application to the electronic device from which the registration was received; and

receiving an IMS application registration for the identified non-native IMS application corresponding to the electronic device from which the registration was received and registering the identified non-native IMS application; and

wherein the activation trigger is a wireless application protocol (WAP) push; and

wherein plural non-native IMS applications associated with the electronic device are identified and activation triggers are transmitted for each identified non-native IMS application, the activation triggers transmitted without waiting for registration of the non-native IMS application associated with any one of the activation triggers.

2. The method of claim 1 , wherein the method is carried out by a server of a communications network and the electronic device is a mobile radio terminal.

3. The method of claim 1 , further comprising maintaining the database by associating the non-native IMS application with the electronic device when enrollment is made for a service supported by the non-native IMS application.

4. The method of claim 1 , further comprising negotiating session initiation protocol (SIP) connections between the non-native IMS application executed by the electronic device and a corresponding IMS application executed by a SIP client.

5. The method of claim 1 , wherein the non-native IMS application is Java based.

6. The method of claim 5 , wherein an application programming interface (API) for the non-native IMS application is one of Java specification request (JSR) 180 or JSR 281.

7. The method of claim 1 , wherein the at least one of a general IMS availability registration from the electronic device or a native IMS application registration from the electronic device is sent from the electronic device when the electronic device is powered on.

8. A non-transitory computer readable medium storing a program, the program for remotely activating a non-native IP multimedia subsystem (IMS) application of an electronic device and comprises executable logic to:

receive at least one of a general IMS availability registration from the electronic device or a native IMS application registration from the electronic device;

respond to the general IMS availability registration or the native IMS application registration by checking a database that associates IMS applications with the electronic device from which the registration was received and identify from the database a non-native IMS application corresponding to the electronic device from which the registration was received for remote activation;

transmit an activation trigger for the identified non-native IMS application to the electronic device from which the registration was received; and

receive an IMS application registration for the identified non-native IMS application corresponding to the electronic device from which the registration was received and registering the identified non-native IMS application; and

wherein the activation trigger is a wireless application protocol (WAP) push; and

wherein upon identification of plural non-native IMS applications associated with the electronic device, the logic to transmit transmits an activation trigger for each identified non-native IMS application, the activation triggers transmitted without waiting for registration of the non-native IMS application associated with any one of the activation triggers.

9. The computer readable medium of claim 8 , wherein the program is executed by a server of a communications network and the electronic device is a mobile radio terminal.

10. The computer readable medium of claim 8 , further comprising logic to maintain the database by associating the non-native IMS application with the electronic device when enrollment is made for a service supported by the non-native IMS application.

11. The computer readable medium of claim 8 , further comprising logic to negotiate session initiation protocol (SIP) connections between the non-native IMS application executed by the electronic device and a corresponding IMS application executed by a SIP client.

12. The computer readable medium of claim 8 , wherein the non-native IMS application is Java based.

13. The computer readable medium of claim 12 , wherein an application programming interface (API) for the non-native IMS application is one of Java specification request (JSR) 180 or JSR 281.

14. The computer readable medium of claim 8 , wherein the at least one of a general IMS availability registration from the electronic device or a native IMS application registration from the electronic device is sent from the electronic device when the electronic device is powered on.
