Abstract:
1. A method for synchronizing a subscriber profile in a plurality of domains, the method comprising steps of: registering a Wi-Fi-enabled dual-mode mobile device at an application server in an Internet protocol (IP) domain, wherein registering the Wi-Fi-enabled dual-mode mobile device includes: authenticating a wireless subscriber associated with the Wi-Fi-enabled dual-mode mobile device, downloading data corresponding to the wireless subscriber from a home location register (HLR) located in a cellular domain distinct from the IP domain, and generating an IP domain subscriber profile using the downloaded data; receiving, at the application server located in the IP domain, a profile update request message from the Wi-Fi-enabled dual-mode mobile device operating in Wi-Fi mode and located in the IP domain, to modify the IP domain subscriber profile associated with the Wi-Fi-enabled dual-mode mobile device, wherein the profile update request message specifies a service feature change, and wherein receiving the profile update request message includes receiving the profile update request message via the IP domain; forwarding the profile update request message to the HLR; modifying, by the HLR, a cellular domain subscriber profile associated with the Wi-Fi-enabled dual-mode mobile device in accordance with the profile update request message, wherein modifying the cellular domain subscriber profile associated with the Wi-Fi-enabled dual-mode mobile device includes modifying a service feature of the cellular domain subscriber profile in accordance with the specified service feature change; receiving updated subscriber profile data from the HLR; converting the updated subscriber profile data in the IP domain; and sending the converted updated subscriber profile data to the application server.
