Abstract: A system and method are provided for updating persistent data in a wireless communications device. The wireless communications device receives patch manager run time instructions from an airlink interface. A run-time engine is launched. The run-time engine receives the patch manager run time instructions with dynamic instruction sets and new code sections, including updated persistent data. The run-time engine processes the dynamic instruction sets. In response to processing the dynamic instruction sets, the run-time engine selectively updates persistent data in the system software. The updated persistent data may, for example, be selected from the following: radio frequency (RF) calibration data, nonvolatile system and user configuration data, resource data, nonvolatile system and user application data, and arbitrary data.

Abstract: Disclosed is a system and method for maintaining software instructions stored in a wireless communications device memory. The software is organized using code sections, where each code section is in a contiguous portion of memory and relocatable independently of other code sections. Maintenance includes the ability to run a unique software component called a compactor while the normal system is not in executable form. The compactor expands, compresses, and relocates code sections to allow downloaded code to be incorporated into the system code base.

Abstract: Systems and methods for modifying the area code in a wireless communication device are provided that provide authorization from the carrier. The wireless communication device contains a table of valid area codes in persistent memory. The table defines the complete set of area codes that can be used by the wireless communication device.

Abstract: Methods to manipulate the mobile wireless device screen more efficiently are provided. The method and devices allow a graphical user interface to be used more efficiently on a mobile handset with limited processing ability. A graphical user interface can be implemented on a mobile wireless device efficiently by limiting processing to only the areas of the display screen on the mobile wireless device that is changing. For example, if a graphical item is to be displayed on the display screen the value in the display screen memory location that will be covered by the graphical item can be stored for future use. If the graphical item is later moved the stored value can be retrieved and efficiently written to the display without the need to recalculate what was behind the graphical item.

Abstract: The present invention provides a peer-to-peer data communication system and method that allows a first handset and a second handset to engage in data communications over a wireless communication network. In doing so, the first handset creates a server opcode set and combines the server opcode set with a corresponding server data payload. The server opcode set and corresponding server data payload are then sent to a network server where the data is extracted and the opcodes are translated into executable instructions that are carried out. The executable instructions cause the network server to compile a remote opcode set and a corresponding remote data payload. This remote opcode set and remote data payload are sent to the second handset, which is identified by the first handset in the server data payload.

Abstract: A system and method are provided for organizing field upgradeable system software in a wireless communications device. The software is organized into a first plurality of symbol libraries or code sections. Contiguously addressed memory blocks store the symbol libraries or code sections. The start addresses of code sections or symbol libraries are stored in a code section address table cross-referencing code section identifiers with corresponding start addresses. Each symbol is offset from its respective code section start address. Symbol identifiers are cross-referenced with corresponding offset addresses, and corresponding code section identifiers in a symbol offset address table. A symbol accessor code is used to identify symbol addresses using the code section address table and the symbol offset address table.

Abstract: Systems and methods for improved security in handset reprogramming are provided that prevent a handset from being reprogrammed in the field without authorization from carrier. When a handset receives a reprogramming request, or detects a reprogramming attempt, the handset contacts the carrier for authorization to be reprogrammed. The network can provide the authorization, deny the authorization, require additional information from the reprogramming device, or contact the reprogramming device directly to authorize the reprogramming. Additionally, the carrier may provide the handset and the reprogramming device each with a private key that can be converted by each device and then compared by the handset to determine if the reprogramming device is authorized.

Abstract: A system and method for expiring a software module on a wireless communication device is disclosed. According to one embodiment, the method comprises receiving, at the wireless communication device, an expiration notice for the software module and determining if license renewal of the software module is automatic. If the license renewal is not automatic, then the method includes notifying a user of the wireless communication device of the receipt of the expiration notice, and de-activating the software module upon receipt of instructions to not renew. In certain embodiments, the software module is de-activated after an expiration of a trial period if no instructions are received from the user in response to the notifying step.
