System and method for efficient transfer of applications and data during device swap

A method, in a wireless device, for registering a back-up of at least one application with an application gateway, the method comprising:

• installing the back-up and associated registration information for the at least one application onto the device;
• after installing the back-up and the associated registration information onto the device, determining, using identification information loaded from the installed back-up and associated registration information, that the back-up has been transferred from another device and that a device change has occurred;
• and
• transmitting, to the application gateway, signals representing:
• identification information for the wireless device, including a notification that the device change has occurred;
• and information regarding the at least one installed application;
• wherein determining that the device change has occurred comprises determining that identification information loaded from the installed associated registration information is different from identification information of the wireless device.

A system for registering a transfer of at least one application between a first and a second wireless device comprising:

• an application gateway having a processor configured to execute instructions to cause the application gateway to:
• store a registration list of identification information of registered wireless devices and a back-up of the at least one application and associated registration information installed on the registered wireless devices, the first wireless device being one of the registered wireless devices;
• receive, from the second wireless device, identification information regarding the second wireless device, including notification that a device change has occurred, and information regarding the at least one application installed from the stored back-up and associated registration information onto the second wireless device;
• and
• update the registration list with the identification information for the second wireless device and the at least one application installed on the second wireless device;
• and
• the second wireless device having a processor configured to execute instructions to cause the second wireless device to:
• install the back-up and associated registration information from the application gateway onto the device;
• after installing the back-up and the associated registration information onto the device, determine, using identification information loaded from the installed back-up and associated registration information, that the back-up has been transferred from the first wireless device and that the device change has occurred;
• and
• transmit, to the application gateway, signals representing:
• identification information for the wireless device, including the notification that the device change has occurred;
• and information regarding the at least one installed application;
• wherein the second wireless device is further configured to determine that the device change has occurred by determining that identification information loaded from the installed associated registration information is different from identification information of the wireless device.
