Description

Failure Notification and Handling Method of Mobile Communication System

The present invention relates to a mobile communication system, and in particular, when a subscriber detects a decrease in call quality during a call, the base station notifies the base station of the corresponding failure code, and the base station receiving the base station diagnoses the failure of the corresponding failure code in the failure diagnosis module. The present invention relates to a method for reporting and handling a fault in a mobile communication system to promptly release a fault caused by an operator.

In general, a mobile communication system is comprised of a mobile telephone, a mobile telephone base station, and a mobile telephone switching office.

Here, a mobile telephone terminal (also called a "mobile station") serves to transmit and receive voice and data signals with a base station, exchange channels and perform location registration, and a mobile telephone base station (also called "cell site") is a data signal and It sends and receives voice over the wireless section, controls the terminal, monitors the call quality, connects the mobile switching center to the terminal, and the mobile switching center performs the switched connection of the mobile telephone network and connects with the public switched telephone network. It performs central control, control and monitoring of base station, call processing and manages billing information, subscriber information and location registration information.

Here, reference numeral 10 denotes a mobile telephone terminal, reference numeral 20 denotes a base station that performs an interface function for service of outgoing calls, incoming calls, and other additional functions through direct wireless communication with the mobile telephone terminal 10. Call processing control unit is a collection of functions driven to provide a service to a subscriber, and reference numeral 40 monitors the state of the system in order to provide a quality service to a subscriber, and provides an operator with a state change that causes disruption to the service. It is a system operation / preservation unit that informs and collects and stores information related to system state change and makes data available for system diagnosis.

In the conventional mobile communication system having such a configuration, first, when a telephone number is input through a keypad in the mobile telephone terminal 10 and a call start button is pressed, a unique number (IN1, MIN2, ESN) and a user stored in the terminal are dialed. The dialed telephone number is transmitted to the base station 20 together.

When the base station 20 receives the unique number and the telephone number transmitted from the mobile phone terminal 10, the base station 20 checks whether the received unique number and the like are registered numbers. The voice channel is assigned to the caller, and thus the user makes a call with the called party through the assigned voice channel.

On the other hand, the conventional mobile communication system as described above has hardware (H / W), software (S / W) fault and alarm detection functions in the system to diagnose faults, alarm states, or self faults. It outputs the result of performing the function to the designated operator screen (Consol, User Interface Window) as a message in the format (Format) to help the operator to understand the system status and take a corresponding recovery action. .

However, during the operation of the actual switching system, there may be a failure that cannot be detected by the failure and alarm detection function, thereby affecting the call quality.

For example, silence due to software or hardware error (a phenomenon in which the subscriber's voice is not heard by the other party), crosstalk, noise, and base station (subsystem of a mobile switching system wirelessly connected to a subscriber's terminal) deployment error or base station For example, poor call quality due to internal problems.

The above problems can be known only through the complaints of general subscribers or direct call test of operators, which causes complaints when settling the charges due to customer complaints about the quality of calls, and reduces the reliability of operators, which in turn causes difficulties in securing customers. .

Accordingly, the present invention has been proposed to solve various problems occurring in the conventional mobile communication system as described above.

According to the present invention, when a subscriber detects a decrease in call quality during a call, the base station notifies the base station of the corresponding failure code, and the base station receiving the same diagnoses the failure of the corresponding failure code in the failure diagnosis module and promptly recognizes the result to the operator.

3 is a flowchart illustrating a failure notification and processing method of a mobile communication system according to the present invention.

As shown in the figure, if a call quality degradation occurs during a call, transmitting a corresponding failure code from a terminal to a base station (BTS); The base station receiving the failure code transmits the received failure code to the call processing module; Analyzing the failure code received by the call processing module and collecting information related to the failure code; Transmitting the analyzed fault code and the collected related information to a fault diagnosis module; Diagnosing a failure of a corresponding failure code in a failure diagnosis module receiving the failure code and related information; Transmitting the diagnosis result and subscriber information to an operator screen control module; Monitoring the diagnosis result and the related information received from the operator screen control module on the operator screen consists of a step for recognizing the failure caused to the operator.

The failure notification and processing method of the mobile communication system according to the present invention as described above will be described in detail with reference to FIG. 2 as follows.

First, when a call is attempted by the same call processing method as before, and a call connection is made with the other party, a call of the mobile terminal 50 confirms whether the call quality is degraded while making a call through its own terminal. do.

If the call quality is degraded during the call, the fault code related to the corresponding fault is transmitted to the base station 60 through the wireless channel.

Here, the failure code is predefined by the operator to inform the terminal user when the terminal purchases. In the above method, a method of notifying a subscriber of a failure code is stored in advance in the RAM inside the terminal and a code indicating a failure indicating the failure code of the failure code, so that the subscriber can access the failure code and any disabled person by any key operation. There are ways to help you become aware of a disability, either by identifying it, or by writing down a disability code and a disability in the brochure (product manual, etc.).

Therefore, if the subscriber is familiar with the failure code by the above method, and the call quality deterioration occurs during the call, the subscriber will determine the cause and transmit the corresponding failure code to the base station.

Here, the transmission method of the error code, DTMF transmission method for transmitting the digits to the wireless channel one by one each time the numeric buttons provided on the keypad, and sequentially pressing the corresponding failure code through the numeric buttons and then the transmission key (SAND key) There is a method to transmit a failure code at a time by pressing) .The transmission method gives the subscriber the option to choose one of two methods to send the failure code, or to memorize the method to send the failure code to the product in advance. There is a method in which the error code transmission method is recorded in the product manual and the user can easily transmit the error code.

On the other hand, if a failure code is transmitted from the mobile telephone terminal 50 in any of the above methods, the base station 60 receives it and transmits the received failure code to the subsequent call processing module 70 as it is. Do it.

When the call processing module 70 receives a failure code, it analyzes the received failure code, collects information necessary for diagnosing the cause of the failure, and transmits the failure code and the related information collected to the failure diagnosis module 80. Do it.

When the fault diagnosis module 80 receives a fault code and related information, the fault diagnosis module 80 performs a fault diagnosis function using the received fault code and related information. When the failure diagnosis function is completed, the operator screen control module 90 transmits the failure diagnosis result and failure information (for example, subscriber information).

The operator's screen control module 90 receiving this monitors the received diagnosis result and related information on the operator's screen. Accordingly, the operator knows which fault occurred in which subscriber or through the screen to solve the problem. And the like.

When the operator recognizes the obstacle as described above, the operator can quickly respond to the recognized obstacle and solve the obstacle so that the terminal user can quickly overcome the degradation of the call quality, thereby always making the call with a clean call quality. It will be possible.

As described above, the present invention provides a diagnostic function corresponding to a corresponding failure by transmitting a corresponding failure code during a call and interpreting a code received from a mobile communication system when the call quality is degraded due to some cause during a call. By taking action and then taking action accordingly, there is an effect that can solve the problem that occurred quickly.

In addition, there is an effect that the call disconnection phenomenon can be prevented by transmitting an obstacle generated during the call and handling the generated error during the call in the mobile communication system.

In addition, since a subscriber in a call notifies a failure occurring during a call, a call failure that cannot be detected in the mobile communication system itself can be detected.
