Abstract:
A method for storing data representing usage of a terminal device, said data comprising a plurality of entries each having a parameter combination associated therewith, said method comprising the steps of:storing a plurality of different parameter combinations in a parameter memory at a terminal device; internally within said terminal device, organizing a statistical memory in said terminal device into a plurality of statistical classes respectively corresponding to said different parameter combinations; allocating a plurality of counters respectively to said different parameter combinations, each counter having a count; storing the respective counts of said plurality of counters in the statistical classes in the statistical memory respectively corresponding to said different parameter combinations; comparing the parameter combination associated with an entry of said data representing usage to the different parameter combinations stored in said parameter memory and, if said parameter combination associated with said entry matches one of said different parameter combinations, incrementing the count stored in said statistical memory by one corresponding to said one of said different parameter combinations; and if no match of the parameter combination associated with said entry is found, re-organizing said statistical memory to include a new statistical class corresponding to the parameter combination of said entry, setting a count of a counter corresponding to said new statistical class to an initial value, and storing said initial value in said new statistical class in said statistical memory.
