The present invention relates to wirelessly diagnosing a failure of a mobile terminal that transmits and receives data to and from a base station wirelessly, such as a mobile communication or a wireless subscriber network (WLL). In particular, the specification of Over The Air Parameter Administration (OTAPA) Wireless remote diagnosis of the fault occurrence status of the terminal by using the, and a simple failure phenomenon relates to a wireless remote diagnosis and failure repair method of the terminal to be repaired by wireless remote control.

A cellular type mobile communication device or a wireless subscriber network (WLL) communicates using a wireless communication channel between a mobile terminal and a fixed base site. It passes between the base stations (Site), the service area of the base station (Site) must communicate with the base station, when moving to the service area of the neighboring new base station, the communication channel from the new base station again It will continue to receive communication.

As described above, when the mobile terminal moves between base stations, it transmits and receives various parameters and data necessary for channel assignment and mutual confirmation, and performs the Over The Air Parameter Administration (OTAPA) function internationally. As a standard or regulation for unification, there is one such as TIA / EIA / IS-683-A, and the 'Reserved For Future Standardization' area, which is not defined in consideration of scalability by future technology development, is used in the OTAPA standard. The present invention relates to a remote diagnosis of a failure of a terminal wirelessly, and to a case of a simple failure, a repair by a remote control wirelessly.

Hereinafter, a wireless remote parameter management method of a terminal according to the prior art will be described with reference to the accompanying drawings.

1 is a flow chart of a terminal parameter management method according to an embodiment of the prior art.

Referring to the accompanying drawings, the order of the terminal parameter management method according to the prior art, the first step (S10) is transmitted to the OTAPA Request MSG to manage the parameters of the terminal from the base station (Site),

The mobile terminal wirelessly receiving the OTAPA Request MSG from the base station (Site) is a second step (S20) for wirelessly transmitting an OTAPA Response MSG to the base station to cooperate with the parameter management request of the base station;

A third step (S30) of transmitting, by the base station, a Validation Request MSG, which is a confirmation request message for managing parameters of the terminal;

A fourth step (S40) of transmitting, by the terminal, a Validation Response MSG which is an authorization message for the parameter management confirmation request message applied from the base station;

If the base station processes the various parameters received in the above step and there is a parameter that needs to be changed, the base station transmits the changed value to the corresponding terminal through the Download Request MSG (S70),

An eighth step (S80) of receiving the changed parameter value as described above, storing it in a memory for a while, and transmitting a Download Response MSG notifying that the reception has been received;

The base station receiving the signal confirms that the terminal has properly received the corresponding parameter value, and transmits a Commit Request MSG to change the memory for storing the content of the terminal to the received parameter value (S90). Wow,

The terminal comprises a tenth step of transmitting a Commit Response MSG informing the base station that the changed parameter value is stored in the storage memory.

Hereinafter, a terminal parameter management method according to the related art having the above configuration will be described in detail with reference to the accompanying drawings.

When a base station of a cellular type mobile communication or a wireless subscriber network (WLL) requests a allocation of a communication channel to enter a service area and receive a communication service, the terminal is registered in the system.

Upon receipt of the message, the terminal transmits an OTAPA Response MSG in the sense of acceptance to the base station (step S20), and the base station receiving the acceptance message starts managing parameters.

The base station transmits a validation request message, which is a confirmation request signal to confirm whether the parameter is ready for transmission again to the corresponding terminal (step 3, S30), and receives a validation response message that is a response signal from the terminal (step 4, S40). Thus, the preparation step is completed.

The base station transmits a configuration request message requesting a parameter to a corresponding terminal (step 5, S50), and the corresponding terminal receiving the signal transmits current NAM parameter information to the base station as a configuration response message. Step 6, S60).

After receiving the NAM parameter value in step S60, the base station analyzes and modifies the parameter value that needs to be changed to a new parameter value, and then transmits it to the corresponding terminal as a Download Request message (step S70). After receiving the signal, the corresponding terminal stores the received parameter value in a corresponding temporary memory, and then transmits a Download Response message indicating that the new parameter value has been received to the base station (S80).

The base station receiving the parameter value retransmitted from the terminal compares the transmitted parameter value with the received parameter value and if it matches without error, Commit Request MSG instructing to apply the parameter value transmitted to the corresponding terminal. (S90) and the terminal receiving the signal stores the new parameter value recorded in the memory in the corresponding dedicated recording memory, thereby applying to the NAM parameter and completing the application Commit Response By transmitting the MSG (step 10, S100), a new parameter value is applied and operated.

However, the method of managing a parameter value of the terminal according to the related art cannot diagnose whether the terminal has a failure or continues to operate normally. Therefore, a malfunction of the terminal is not detected in advance and the terminal is left as a result. Increasing user dissatisfaction, deepening the failure of the terminal has a problem of lowering the reliability of the system.
