Push Based Encryption

A method for introducing a replacement code segment over-the-air through a wireless mobile communication network to an existing code resident on a mobile terminal, the method comprising:

• identifying the mobile terminal from among terminals served through the wireless mobile communication network;
• sending a push notification through the wireless mobile communication network to a data communication module resident in the mobile terminal, said push notification indicative of the replacement code segment ready for downloading;
• activating a dynamic update module resident in the mobile terminal, in response to the push notification;
• initiating a data communication session from said data communication module resident in the mobile terminal, through the wireless mobile communication network;
• sending a request for the replacement code segment, indicated in said push notification, via said data communication session;
• downloading the replacement code segment for the mobile terminal to the data communication module resident in the mobile terminal, via said data communication session;
• and
• transferring the downloaded replacement code segment to said dynamic update module for dynamic replacement of a corresponding old code segment within the mobile terminal with the replacement code segment, obviating a need to recompile the existing code.
