Patent ID: 8301780

Claim:
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 a wireless network at the application client executing on the subscriber unit, the registration process including: determining whether a standalone application platform for the network application of the wireless network is detected or not detected, wherein the standalone application platform is an application server that is not integrated with an IMS network of the wireless network; and when the standalone application platform of the wireless network is detected, initiating a standalone mode registration process between the standalone application platform and the application client in response to detecting the standalone application platform; and when the standalone application platform of the wireless network is not detected, checking to determine if an application availability notification has been received; and initiating, in response to receiving the application availability notification and instead of the standalone mode registration process, an integrated mode registration process between the application client and the IMS network of the wireless network.
