<p>A system (10) for remote patching or updating of operating code located in a mobile unit (22, 24, 26, 28 or 30) is provided. The system (10) includes a manager host (16) and a mobile unit (22, 24, 26, 28 or 30). The manager host (16) is operable to initiate transmission through a communication network (12) of at least one discrete patch message defining at least one patch. The mobile unit (22, 24, 26, 28 or 30) is operable to receive the at least one patch message. The mobile unit (22, 24, 26, 28 or 30) is also operable to create patched operating code by merging the patch with current operating code located in the mobile unit (22, 24, 26, 28 or 30) and to switch execution to the patched operating code. The mobile unit (22, 24, 26, 28 or 30) can also receive at least one download message defining new operating code to replace the current operating code.</p> |
