Abstract: An improved method of updating parameters stored in memory of mobile telecommunications stations. An object model represents all the parameters that can be modified in an IS-683A mobile station. The details of the physical location of each parameter are defined in this mobile object model. Advantageously, when any parameter is changed or added, it is necessary to provide the computer system, which generates messages to be transmitted to the mobile station, only the identification and value of the parameter to be added or changed. The computer system then generates a message sequence that defines the memory location in the mobile station to be changed, and the new value of the data for that memory location. Advantageously, this arrangement sharply reduces the total number of airwave messages transmitted to the mobile station in order to change or add a parameter.

Abstract: A fault recovery system and method that deterministically reconstructs the instruction stream of a multiple execution stage ("pipelined") processor. A log ("queue") is provided for each critical data item to record the instructions, operations and effects as processing proceeds. Also, rather than merely freezing the execution of a specific stage upon occurrence of a fault, all stages are stopped so that each stage does not overwrite log information that is needed to reconstruct the instruction flow immediately preceding the invocation of any fault recovery operation. The fault recovery operation may then serially reconstruct the instruction flow, advantageously starting with the instruction where the fault occurred, working to reconstruct from that instruction to the last instruction that was executing before the fault recovery operation began.
