Abstract

PURPOSE: A method for transmitting and collecting information on a base station is provided to output all information output from each processor to a console to a BSM(Base station Manager), thereby capable of managing each base station without patrolling each base station. CONSTITUTION: A base station receives a CRM(Connection Request Message) for requesting console output information from a base station controller management system(S10). The base station corrects a routine for charging the final output terminal of the console output and transmits the console output information to the console and BSM(S20). Thereafter, the base station transmits a CAM(Connection Answer Message) to the BSM(S30) in response to the CRM. When generating a console output request from a processor of the base station, the base station outputs data to the console and performs a data buffering and when the buffer is filled with the data, the data is transmitted to the BSM(S40). When the data is not transmitted to the BSM during the specific time, the data is transmitted to the BSM irrespective of the filling of the buffer(S50). When a connection cancel signal is received, the base station cancels the connection and outputs the information to the console of the base station(S60).

Description

METHOD FOR FORWARDING AND COLLECTING INFORMATIONS REGARDING BASE STATION TRANSCEIVER}

The present invention provides a method for transmitting and collecting base station information in a mobile communication system, in particular, by a processor operating at each base station according to a request of a base station controller management system (hereinafter referred to as "BSM") to a console. The present invention relates to a method for transmitting and collecting base station information in a mobile communication system that facilitates base station maintenance by allowing all information to be outputted to a BSM so that each base station can be managed without looking directly.

Referring to FIG. 1, a general mobile communication network includes a plurality of mobile stations, a base station transceiver (2), a console (3), a base station controller (BSC), and a base station controller management system (BSM) (1). It consists of. The base stations (BTSs) serve to connect the terminals of the mobile communication network with the terminals, and perform functions such as terminal maintenance and call channel allocation / release. On the other hand, the base station controller (BSC) is located between the exchange and the base station to manage base station operations, manage hardware and software in the base station, allocate and configure resources for call traffic, collect information on base station operations, and detect them. It performs functions such as monitoring of the lower device related to the fault. The base station manager monitors the hardware and software status of multiple base station controllers (BSCs), configuration management, base station information collection, base station operation monitoring, and subsystems related to detected failures. Functions such as collecting command data.

The digital mobile communication system installs a plurality of base stations in all areas where subscribers are expected to move to provide a seamless communication service to subscribers moving to a wide area. Therefore, a large number of people and equipment are required to maintain the equipment, and due to problems such as cost, each base station is installed unattended and the base stations are bundled in a certain number and managed remotely through the BSM (1) in one region. Processes that operate at many base stations 2 scattered across a wide area (hereafter referred to as "BCP") and processes that operate on BSMs trunk trunked information along a fixed format of previously agreed communication protocols. Through the BSM, the process within the BSM processes and outputs the information received from the base station in a form easily understood by the operator of the BSM so that the status of the base station can be monitored and managed. The process running at the base station outputs free information directly through the console installed in the specific base station. Therefore, when a problem occurs in a specific base station, the operator must move directly to the base station to solve the problem. However, most of the problems that occur at the base station, in addition to the need to go to the base station, such as replacement of equipment, there is also a problem of a specific base station itself or a specific communication packet between the base station and the BSM, so even if you do not necessarily go to the base station, There are situations where you can solve the problem by checking the output statement. The basic information can be confirmed through the interworking of the existing BSM and the base station, but since the information is processed and transmitted to the operator through all the software blocks of the base station and the BSM, the information is more likely to be inaccurate and perfect software is implemented. Therefore, information about the problem of the base station hardware or the software itself is not known to the BSM. Such information can be understood by comparing and analyzing the information inserted and deleted by the developer frequently outputted to the console of the base station with the information output from the BSM. For this analysis, the operator had to traverse the base stations in many regions one by one. However, because the base stations are scattered in a wide area, operators or developers must find each base station and collect the information in order to collect the base station information, which not only causes a lot of time and labor, but also solves a problem. The consumption of time has caused a problem that the reliability of the entire mobile communication system is degraded due to the interruption of the mobile communication service.

The present invention overcomes the problems of the prior art described above, an object of the present invention is to improve the problem of base station management by the BSM to reduce the base station maintenance cost by reducing the maintenance personnel of the base station and to solve the problem and its solution It is to provide a method for transmitting and collecting base station information in a mobile communication system that can quickly grasp and respond immediately to improve the reliability of the mobile communication system.

That is, in one aspect of the present invention, when the base station receives a connection request message (hereinafter referred to as " CRM ") from the base station controller management system (BSM) requesting the console output information, the console output information only for the console. Transmitting to the BSM as well;

Sending a response message (hereinafter referred to as "CAM") in response to the console information output request sent from the BSM;

Outputting to the console when a console output request is generated from a process on the base station, buffering data and transmitting the buffer to the BSM when the buffer is full;

Sending data to the BSM regardless of whether the buffer is full if there was no transmission to the BSM for a particular time; And

When receiving the disconnection signal from the BSM disconnection, and to provide a base station information transmission method comprising the step of outputting information only to the base station console.

Another aspect of the present invention includes transmitting a CRM to a requested base station with a key having a random value when there is an output request for console output information of a specific base station of an operator;

Confirming the connection upon receiving the CAM from the base station and periodically transmitting the CRM with a key set at the time of initial generation to the base station; And

And checking the CAM from the base station to determine whether the disconnection of the signal exceeds a specified number of times, and determining that the state of the base station is incapable of transmitting and releasing the connection.

3 is a flowchart of a base station acquisition transmission method in a base station controller management system according to the present invention.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

According to the method of the present invention, when there is an operator request on the BSM, all the detailed information outputted to the console by a process operating at each base station is output to the BSM so that the operator can know exactly without moving to various regions. It is done. Modification of system call for screen output of the operating system without modification of all the software currently running on the base station. Debugging information that the base station software developer adds / deleted from time to time to solve the problem and the process that operates on the base station. (BCP) Outputs the console information to the base station console and, at the request of the BSM operator, transmits the traffic and control information between the base station and the BSM to the BSM through the E1 / T1 trunk installed. do. Since the information transmission between the existing base station and the BSM is performed according to the defined protocol between the applications necessary for the operator operating on the operating system on the base station, information that is frequently inserted / deleted by the person in charge of software development is transmitted to the BSM. Since it is difficult, the operating system outputs all output requests of the application to the console and directly to the BSM so that the inserted information is transmitted to the BSM without requiring any change of the application.

2 is a flowchart of a method for transmitting base station information in a base station according to the present invention. Referring to FIG. 2, a method of transmitting base station information according to an aspect of the present invention first receives a connection request message (CRM) requesting console output information from a base station controller management system (S10).

When receiving the message, the base station modifies the routine (Routine) in charge of the final output stage of the console output and transmits the console output information to the BSM as well as the console (S20).

Subsequently, the base station transmits a response message (Connection Answer Message) for the information output request to the BSM in response to the CRM transmitted from the BSM (S30). Since CRM is periodically transmitted from BSM, CAM is also periodically transmitted to BSM.

It determines whether CRM is transmitted by a fixed number. If it is not transmitted by a predetermined number, it determines that there is a problem with the BSM process and stops BSM transmission of information to prevent loss of process time. The threshold can be arbitrarily set here, usually about five.

When a console output request is generated from a process on the base station, the console outputs the data, buffers the data, and transmits the data to the BSM when the buffer is full (S40).

In order to prevent the data from remaining in the buffer because the buffer is not full, if there is no transmission to the BSM for a specific time, the data is transmitted to the BSM regardless of whether the buffer is full (S50).

On the other hand, in order to prevent the overhead of double outputting the same information to the BSM, when receiving a CRM with a key different from the CRM that currently requires data transmission setting, the CRM that is later ignored is ignored. Commands sent from the BSM execute commands in the same way as console input.

When the base station receives a disconnection signal from the BSM, the base station releases the connection and outputs information only to the base station console (S60).

Another aspect of the present invention is a method of collecting base station information in a base station controller management system. First, in this aspect of the present invention, when there is an output request for console output information of a specific base station of an operator, the CRM is transmitted to the requested base station together with a key having a random value (S100).

When the CAM is received from the base station for the CRM, it checks the connection and periodically transmits the CRM with the key set at the time of initial generation to the base station. When the process becomes inoperable due to an unexpected problem, the situation is not recognized. By continuing to transmit information from the base station to prevent the process time of the base station is consumed (S200).

It checks the CAM from the base station to determine if the signal disconnection exceeds the specified threshold. If it exceeds, it determines that the base station is incapable of transmitting and releases the connection. If it does not exceed the threshold, it increases the count and increases the CAM again. Enter the waiting state (S300).

In this embodiment, when the CAM is first disconnected, first, the base station assumes that a problem occurs during initialization and transmits the CAM as soon as possible and reconnects as soon as possible to prevent loss of information according to the CAM transmission cycle.

When receiving the disconnect request request command of the operator requests the disconnection to the base station, and other commands transmit the command to the base station.

The present invention emulates a base station console on a BSM, modifies the OS of the base station, and transmits the information outputted to the base station console to the base station console emulator of the BSM, so that all existing software is not modified at all. By making the information available to the BSM, maintenance of each base station can be facilitated, and the reliability and quality of the mobile communication service can be improved.
