METHOD OF PREVENTING LONG RUN TASK IN ENVIRONMENT OF REALTIME MULTITASKING OPERATING SYSTEM

摘要

PURPOSE: A method of preventing long run task in environment of RMOS(Realtime Multitasking Operation System) is provided to reduce operating time to each task by reducing depth of successive function calls, and optimize code on procedure to end all tasks in one hundred minutes that RMOS allows. CONSTITUTION: A method of preventing long run task in environment of realtime multitasking operation system comprises the following courses. The course that replaces successive call function to signal transmitting, comprises the steps of: registering signal for operating header with relevant function; after registering signal, using a signal transmitting primitive that OS provides; with using the signal transmitting primitive, transmits signal to OS for operating only the functions that called among other functions; and with transmitting signal to OS, operating functions that called apart from functions that will be called; the functions that called by operation processed ends operating the functions after transmitting signal. The course that retrieves buffers related to syntonic FA(Frequency Assignment) when the system receives transmission and receipt response messages. It comprises the steps of: retrieving 450 buffers of array size that relevant to syntonic FA; and retrieving periodically buffers that relevant to other FA. The course that watches checking state of traffic channel element equipped in each FA periodically. It comprises the steps of: to make each FA operate separately every two minutes, registering BTS control processor initially when it is active state; searching state of FA that equipped; retrieving traffic channel elements, equipped in a channel interface processor, equivalent to the number of maximum channel interface processor to a base station; and searching traffic channel element whether a channel interface processor is equipped and it is in relevant FA; if so, inspecting state of traffic channel element and processing it, if inconformity occurs.
