PURPOSE: A signal recording method in a data service in a mobile communication area is provided to facilitate debugging by simply checking an error case type without changing a source for debugging for a specific error case in its occurrence among many calls by sequentially storing every signal generated from one call reference by taking a call reference value as a key. CONSTITUTION: An FRI block registers a routine defined to be operable in a user program itself in an OS and a trigger which is able to operate the trigger, that is, substantially, a 'trace' command 'next' commands(S1). It is determined whether the input command is a registered one(S2). If the inputted command is a registered one, it is determine whether the instruction word is 'trace' or 'next' instruction word(S3). If the instruction word is 'trace', it is checked whether the link number is a normal value(S4). If the link number is normal, it is checked whether a trace flag is ON or OFF(S5). If the flag is OFF, the flag is turned ON and at the same time a buffer is initialized to store an error case(S6). If the flag is ON, it is regarded as an OFF instruction word of a trace function so that an error occurrence case of a corresponding link is outputted and the flag is turned OFF(S6') If the instruction word is 'next'(S3), it is checked whether an error case has been completely outputted(S4-1). If the error case has not been completely outputted, the error case is outputted by every one screen(S5-1). If an instruction word which has not been registered is inputted(S2), when an IPC and an IWF signal is received, they are analyzed(S3-2). If the trace flag is ON(S4-2), a name and a major parameter of the signal being currently processed are stored(S5-2). |
