Differential configuration updates for mobile devices

A computer-implemented method including:

• loading a legacy configuration file including a plurality of legacy blocks, each of the plurality of legacy blocks including a type, an identifier, and a payload;
• loading an updated configuration file including a plurality of updated blocks, each of the plurality of updated blocks including a type, an identifier, and a payload;
• for each updated block of the plurality of updated blocks:
• identifying one legacy block from the plurality of legacy blocks having the same type as the updated block and a payload representing a nearest match to the payload of the updated block, and
• in response to the identified one legacy block not having a matching payload to the payload of the updated block:
• determining an amount of difference between the payload of the identified one legacy block and the payload of the updated block, and
• in response to the amount of difference satisfying a threshold, generating an update data object based on a comparison of a portion of the payload of the identified one legacy block and a portion of the payload of the updated block and adding the update data object to a difference file;
• and
• transmitting the difference file to a mobile device via a radio network to update the legacy configuration file stored at the mobile device.

A non-transitory computer-readable medium comprising executable instructions, wherein the executable instructions include:

• loading a legacy configuration file including a plurality of legacy blocks, each of the plurality of legacy blocks including a type, an identifier, and a payload;
• loading an updated configuration file including a plurality of updated blocks, each of the plurality of updated blocks including a type, an identifier, and a payload;
• for each updated block of the plurality of updated blocks:
• identifying one legacy block from the plurality of legacy blocks having the same type as the updated block and a payload representing a nearest match to the payload of the updated block, and
• in response to the identified one legacy block having a matching payload to the payload of the updated block but a different identifier than the identifier of the updated block, generating an update data object based on the identifier of the legacy block and the identifier of the updated block and adding the update data object to a difference file;
• and
• transmitting the difference file to a mobile device via a radio network to update the legacy configuration file stored at the mobile device.
