Abstract

A client-based solution for seamless access to applications across networks is agnostic to the inter-network mix of application architectures with or without IMS. In one embodiment, an application client registers in either an integrated mode or a standalone mode based whether an application availability notification is received within a predetermined period of time.

Claims

1. A method for registering an application client with a network application across an inter-network mix of application architectures with or without IP Multimedia Subsystem (IMS), the method comprising:

initiating a registration process for registering the application client of a subscriber unit with the network application of the wireless network at the application client executing on the subscriber unit, including;

determining if an application availability notification has been received, wherein;

in response to determining that the application availability notification has been received, initiating an integrated mode registration process between the application client and an IMS network of the wireless network; and

in response to determining that the application availability notification has not been received, determining after a predetermined period of time if a standalone application platform for the network application of the wireless network is detected, wherein the standalone application platform is an application server that is not integrated with the IMS network of the wireless network; and

initiating a standalone mode registration process with the standalone application platform in response to detecting the standalone application platform of the wireless network and instead of initiating the integrated mode registration process.

2. The method of claim 1, wherein the network application is a push-to-talk application.

3. The method of claim 1, wherein the determining if a standalone application platform for the network application of the wireless network is detected includes querying a domain name server of the wireless network for a location server address.

4. The method of claim 3, wherein the standalone application platform is detected if the location server address is resolved.

5. A wireless subscriber unit which is agnostic to an inter-network mix of application architectures with or without IP Multimedia Subsystem (IMS), the subscriber unit comprising:

memory containing an application client and instructions for registering the application client with a network application; and

a processor coupled to the memory, the processor to execute the instructions and wherein the instructions include;

initiating a registration process for registering the application client of the subscriber unit with the network application of a wireless network at the application client executing on the subscriber unit, including;

determining if an application availability notification has been received, wherein;

in response to determining that the application availability notification has been received, initiating an integrated mode registration process between the application client and an IMS network of the wireless network; and

in response to determining that the application availability notification has not been received, determining after a predetermined period of time if a standalone application platform for the network application of the wireless network is detected, wherein the standalone application platform is an application server that is not integrated with the IMS network of the wireless network; and

initiating a standalone mode registration process with the standalone application platform in response to detecting the standalone application platform of the wireless network and instead of initiating the integrated mode registration process.

6. The subscriber unit of claim 5, wherein the network application is a push-to-talk application.

7. The subscriber unit of claim 5, wherein the determining if a standalone application platform for the network application of the wireless network is detected includes the processor querying a domain name server of the wireless network for a location server address.

8. The subscriber unit of claim 7, wherein the standalone application platform is detected if the location server address is resolved.

9. A computer program product comprising:

a non-transitory computer readable medium having computer program code embodied therein for registering an application client with a network application across an inter-network mix of application architectures with or without IP Multimedia Subsystem (IMS), wherein the computer program code comprises computer readable program code to;

initiate a registration process for registering the application client of a subscriber unit with the network application of the wireless network at the application client executing on the subscriber unit, including;

determining if an application availability notification has been received, wherein;

in response to determining that the application availability notification has been received, initiating an integrated mode registration process between the application client and an IMS network of the wireless network; and

in response to determining that the application availability notification has not been received, determining after a predetermined period of time if a standalone application platform for the network application of the wireless network is detected, wherein the standalone application platform is an application server that is not integrated with the IMS network of the wireless network; and

initiating a standalone mode registration process with the standalone application platform the standalone application platform of the wireless network and instead of initiating the integrated mode registration process.

10. The computer program product of claim 9, wherein the network application is a push-to-talk application.

11. The computer program product of claim 9, wherein the determining of whether a standalone application platform for the network application of the wireless network is detected includes querying a domain name server of the wireless network for a location server address.

12. The computer program product of claim 11, wherein the standalone application platform is detected if the location server address is resolved.
