Abstract

PURPOSE: A system availability rate measuring method in a WLL(Wireless Local Loop) is provided to prevent an error or down of a system possibly caused due to an overload in advance by computing a system use time and monitoring an overload of the entire WLL system. CONSTITUTION: A CPU receives a base station controller availability rate measuring instruction, the CPU determines whether the currently proceeding process is terminated and switched to a new process of the next order stored in a preparation list(302). If the process switching has occurred(304), the CPU records the ending time of the terminated process in a memory(306). The CPU records a starting time of the new process of the next order in the preparation list in the memory(308). The CPU computes an execution time of the currently terminated process(310). The computed process execution time is accumulated and updated in the process execution time stored in the memory(312). The CPU displays the base station controller execution time, that is, information of the availability rate of the system of the base station controller, for an operator's proper measure(314).

Description

Method of Measuring System Availability in Wireless Subscriber Network

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for measuring system availability in a wireless local loop (hereinafter, abbreviated as WLL), and more particularly, to a method for measuring availability of a processor installed in a base station controller of a WLL.

As is well known in the art, WLL is a telephone system method that wirelessly connects subscriber lines within about 2 to 6 km from a plurality of base stations without using existing public telephone lines.

The WLL system includes a base station that provides communication services to wireless / wired subscribers, a base station controller that is wired to a plurality of base stations, and a personal communication exchange that is wired to the base station controller to switch between subscribers.

However, the commercial Real Time Operating System, which is used to manage and control the entire system in the existing WLL, is used to calculate busy time per process (or task) for system overload measurement. Since there is no built-in algorithm, there is a problem that a system error occurs or a system crashes when an overload is applied to the WLL system, especially the base station controller.

Therefore, the present invention has been made to solve the above-mentioned drawbacks of the prior art, and an object thereof is to provide a method for monitoring the overload of the entire WLL system by calculating the usage time of the system, that is, the availability of the system. .

In order to achieve the above object, the present invention provides a method for measuring a base station controller availability of a wireless subscriber network, in response to a system availability measurement command, determining whether a switchover to a new process occurs according to the termination of a process currently being processed. Recording an end time of the terminated process and a start time of a new process in a memory; calculating an execution time of the terminated process; and accumulating and updating the calculated execution time in an execution time stored in the memory. It provides a method for measuring the system availability of the wireless subscriber network comprising the step of displaying the information on the updated execution time to the system operator.

The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings.

1 is a configuration of a WLL employed in measuring system availability according to the present invention.

As shown, the WLL system includes a personal communication exchange capable of performing a mobile / fixed service, and a plurality of first and second devices connected to the personal communication exchange 122 to perform functions such as call control to the personal communication exchange. ,..., N-th base station controllers 112, 114,..., 116 and each of the base station controllers 112, 114,..., 116 and a plurality of personal communication terminals / fixed terminals (not shown). And a plurality of base stations 102... 104... 106...

The personal communication exchange 122 performs a function of providing an exchange function between personal communication subscribers including mobile subscribers and fixed subscribers.

Each base station controller 112, 114, ..., 116 performs functions such as matching and call control with a plurality of base stations 102 ..., 104 ..., ..., 106 ... do.

Multiple base stations 102... 104,... 106, 106... Belong to their corresponding base station controllers 112, 114,..., 116. Match with subscriber.

FIG. 2 is one of the plurality of base station controllers 112, 114, ..., 116 of the WLL shown in FIG. 1, for example, the first base station controller 112 and its plurality of base stations 102, ... Detailed block diagram showing the connection between

The first base station controller 112 includes a main processor CPU 212 and a memory 214, and the CPU 212 in the first base station controller 112 receives each base station 102, ... Process the signal.

Substantially, the signal received from each base station is input to the ready list (not shown) and waited in order as a process to be processed by the CPU 212.

According to the present invention, the CPU 212 calculates the total execution time of the processes sequentially provided in the ready list, and the memory 214 stores the start time and end time for every process executed by the CPU 212. And accumulates and stores the process execution time calculated therefrom.

Hereinafter, a method of measuring the availability of the base station controller according to the present invention will be described in detail with reference to FIG. 3.

The method of the present invention receives a step 302 of receiving a base station controller availability rate measurement command from an operator through the personal communication switch 122 while the CPU 212 in the base station controller 112 is carrying out the processes in the order of the processes stored in the ready list. Starts from).

In step 302, when the CPU 212 receives a base station controller availability measurement command, the CPU 212 determines whether a transition to a new process of the next rank stored in the ready list has occurred by ending the process currently in progress. (Step 304).

If it is determined in step 304 that no process switch has occurred, it returns to step 304 to determine whether or not the process switch has occurred repeatedly.

However, if it is determined in step 304 that a process switchover has occurred, the end time of the terminated process is recorded in memory 214 (step 306).

The start time of the next rank new process in the ready list is then written to the memory 214 by the CPU 212 (step 308), and proceeds to the next step 310.

In step 310 the CPU 212 calculates the execution time of the currently terminated process described above. The calculation of this execution time is calculated as "process end time-process start time".

The process execution time calculated at step 310 is accumulated and updated at the execution time of the storage process in the memory 214 (step 312).

In a next step 314, the CPU 212 displays to the operator information recording the execution time of the base station controller, which is calculated in step 310 and stored in the memory 214, that is, the availability of the system of the base station controller. Allow the operator to take appropriate action (step 314).

As described above, the present invention measures the availability of the system of the WLL, thereby preventing the system from failing or failing, which may occur due to excessive load of the system.
