Description

Apparatus and method for diagnostic monitoring radio port in W-CDMA WLL system for wideband CDA wireless subscriber network system

The present invention relates to a base station (Radio Port, RP) diagnostic monitor (DM) of a wideband code division multiple access (CDMA) wireless local loop (WLL) system. The present invention relates to a base station diagnostic monitoring apparatus and method for a broadband CDMA wireless subscriber network system suitable for maximizing the stability and efficiency of the base station diagnostic monitoring by performing the monitoring by hardware.

In general, CDMA sets the n-bit 0, 1 random pattern (referred to as a spreading code) for the normal method of transmitting PSK (Phase Shift Keying) with a bit flow of 0 and 1. The inverted signal is transmitted at a bit rate n times the bit rates of the 0 and 1 messages of the message flow, respectively, so that the frequency spectrum width of the signal is spread.

The WLL system using the CDMA wireless access standard can be divided into N-CDMA (Narrowband-CDMA) (IS-95) and W-CDMA (Wideband-CDMA). -CDMA system has difference in frequency bandwidth, voice band data rate and ISDN BRI (2B + D) service.

In addition, the wireless subscriber network system is a system that replaces a predetermined section between each subscriber's home and the public switched telephone by wireless instead of wires in the existing Public Switching Telephone Network (PSTN) system. A mobile terminal (MT) that receives a user's signal from a telephone (TE) in a home and transmits the signal to a base station, and wirelessly connects a bearer to the subscriber's radio interface unit (RIU). And a base station controller (BSC) that performs a function of connecting a call link between the switch and the base station (RP), a base station controller (BSC), and an existing public line switching network. (PSTN) and a wireless subscriber line network switch (MSC) that is responsible for establishing the link for the call.

Therefore, the wireless subscriber network can easily install the telephone network than the existing wired network system, the cost of facility expansion is low, and the flexibility of the network design according to the increase of subscribers has the advantage.

In addition, unlike conventional narrowband CDMA networks, W-CDMA wireless subscriber systems enable the implementation of integrated services digital network (ISDN) services and packet networks as well as call, fax and data transmission. .

As shown therein, reference numeral 1 is a computer equipped with a program for performing base station diagnostic monitoring, and 2 is a base station.

Thus, W-CDMA WLL RP DM (Base Station Diagnostic Monitoring) is a software that is composed of Graphic User Interface (GUI) using Microsoft Foundation Class library (MFC) to run on notebook computer (1). It is configured to identify and monitor the status of the base station.

The functional components include a base station information output function, a wireless section characteristic output function, a message output function, a data logging function, and the like.

FIG. 2 is a software block diagram illustrating a diagnostic monitoring of a base station in FIG. 1, and FIG. 3 is a flowchart illustrating a method for monitoring and monitoring a base station of a conventional broadband CDMA wireless subscriber network system.

As shown in the figure, the WLL base station diagnostic monitoring software establishes a TCP / IP (Transmission Control Protocol / Internet Protocol) connection, and then connects to the diagnostic monitoring task inside the main unit of the WLL base station to select a menu on the GUI screen ( ST1 to ST4); If the menu is a graph, it is processed by the modem unit. If the menu is a function related to the base station configuration information, the main controller is processed. If the menu is a message output function, the main processor is processed by the call processing unit. Performing steps ST5 to ST8; After performing the diagnostic monitoring task of the main control unit, the data is processed by the diagnostic monitoring software of the WLL base station, and the graph output function, the base station configuration information output function, the message output function, and the data logging function are output to output the data of the result. Steps ST9 to ST14 are performed.

In principle, it is desirable to efficiently identify the various states and conditions of the WLL base station through several screens at the same time.However, basically, the WLL base station diagnostic monitoring program collects and processes information by requesting each unit of the base station from the GUI. As such, excessive information demands on the WLL base station can interfere with smooth call processing, which is the inherent purpose of the WLL base station, and may cause performance degradation.

Therefore, demanding complex functions or requiring multiple functions at the same time can place unnecessary load on the WLL base station. Therefore, the WLL base station diagnostic monitoring software should be subject to appropriate functional constraints.

However, since the conventional base station diagnostic monitoring is configured and operated in software, there is a disadvantage in that the speed of performing the diagnostic monitoring of the base station is changed according to the type of the notebook computer 1.

In addition, when performing several functions at the same time, there is a problem that a lot of load on the WLL base station, may put a burden on the call processing that is the original purpose of the WLL base station.

In addition, there is a problem that the operator who performs the WLL base station diagnostic monitoring may acquire the wrong information about the WLL base station by causing a malfunction in an unexpected unexpected situation due to a software bug that all programs hold.
