Abstract

PURPOSE: A repeater management system of a mobile communication network is provided to minimize a facility cost by monitoring a system of an RF repeater for an existing network by using an NMS(Network Management System) of an RF repeater for a new network. CONSTITUTION: A controller of an NMS(200) monitors a system of an RF repeater(100) for a third-generation upon receiving various operation signals of the RF repeater(100) and outputs an NMS control signal. An alarm signal generator(15) of the second-generation RF repeater(10) generates various alarm signals according to an operation of the second-generation RF repeater(10), and outputs them. The thusly outputted various alarm signals are inputted to a controller of the NMS(200). When the RF repeater(100) has an error, an NMS terminal generates system-related information including a failure history and a failure grade, and displays it. A system operator and/or manager can checks generation of a failure of the second-generation RF repeater(10) and the third-generation RF repeater(100) through the NMS(200).

Description

REPEATER MANAGEMENT SYSTEM FOR A MOBILE COMMUNICATION NETWORK}

The present invention relates to a repeater management system of a mobile communication network, and more particularly, to a repeater management system of a mobile communication network to perform a system monitoring function of an RF repeater for an existing network using a network management system (NMS) of a new network RF repeater. It is about.

As the development of the mobile communication system is advanced, various public and private mobile communication services such as vehicles, individuals, the public, data, and messaging using wireless access technologies such as cellular, cordless, and satellite are provided.

This is often categorized into generations: first generation (1G) is divided into analog cellular, second generation (2G) is digital cellular, and third generation (3G) is divided into Future Public Land Mobile Telecommunication Systems (FPLMTS). IS-95A / B is classified as 2nd generation, CDMA2000 1X is classified as 2.5th generation, and Wideband Code Division Multiple Access (WCDMA) is classified as 3rd generation.

In addition, since the 3rd generation mobile communication system starts service in an area smaller than the existing 2nd and 2.5th generation mobile phone service areas, the 3rd generation mobile communication network is constructed with the 2nd generation (or 2.5th generation) overlay. The region will exist.

On the other hand, RF repeaters are usually installed when shielding spaces in mobile communication networks or small base stations in underground areas, tunnels, underground parking lots, etc., when installing a base station or when it is not suitable to operate a relay vehicle. It extracts the weak signal to be relayed from the signals existing in the space or shadow area and amplifies it with low noise.

In addition, an NMS (Network Management System) is optionally employed to monitor the operational status of the RF repeater. This NMS serves to display the fault level (Major, Critical, Minor) along with the fault details when the RF repeater fails. Perform. System operators and / or administrators can check the failure of the RF repeater through the NMS.

However, the adoption of NMS causes an increase in equipment cost, so most of the second generation (or 2.5 generation) mobile communication networks do not employ NMS for low power RF repeaters. The RF repeater that is not provided with the monitoring function may be lost, and it is difficult to identify the material by the user's arbitrary transfer.

In order to solve this problem, a large investment cost is generated due to equipment removal cost, equipment performance improvement cost, and new facility cost, so that the current 2nd generation (or 2.5th generation) mobile communication network cannot solve the above problems.

The present invention has been proposed to solve such a conventional problem, and performs the system monitoring function of the RF repeater for the existing network using the NMS of the RF repeater for the new network in the overlay area to build a new network in the existing network is established area The purpose of the present invention is to provide a repeater management system of a mobile communication network.

And monitoring the existing RF repeater for the existing network based on the alarm signal output from the alarm signal generator.

In another aspect of the present invention, a repeater management system of a mobile communication network is intended to establish a new network through a mobile communication system including an RF repeater having an NMS in an area where an existing network is established by a mobile communication system including an RF repeater.
