BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable terminal employing a digital European codeless communication (DECT) method in a wireless telephone network system. In particular, when a user requests a connection through a portable terminal, the corresponding communication path is not connected. An output method and apparatus for outputting a disconnected factor.

In general, a wireless telephone network system transmits and receives data by wirelessly establishing a network between a fixed station (or wireless base station) and a portable terminal (or mobile phone), and uses a DECT method of transmitting and receiving digital data. The portable terminal employed is a kind of mobile phone used in such a wireless telephone network system.

Such a portable terminal may not be able to be connected by phone due to various factors. For example, if the location of the terminal is deep underground and it is impossible to transmit or receive to the station, when the station can transmit and receive, but all the time slots in the station are in use, many terminals try to connect to each other. If a continuous collision occurs due to severe noise around the terminal due to a high error rate during the call as well as a partial defect in the other terminal may not be connected to the call.

If the connection to the call is not made due to any one of the causes of the non-connection by these various calls, the subscriber can only recognize that the call is impossible and the cause of the connection is not correctly identified. There was a problem that it was not possible to take action accordingly.

Accordingly, an object of the present invention is to enable the user to recognize the cause of non-connection to the call when the call is not connected when the user requests a call to the call using the portable terminal to solve the above problems.

Power supply unit 103 for controlling, power supply display unit 104 for displaying whether power is supplied, to control all functions of the terminal, and in particular, so that the user can recognize the cause of non-connection when disconnected by a call according to the present invention. A decoding signal for converting the PCM data into analog form and restoring the PCM data to restore the encoded data received by the central processing unit 102 and the central processing unit 102 for controlling the function of the terminal. Speaker 105 for outputting the analog signal output from the processing unit 105, the decoding signal processing unit 105 as a voice signal, the user's voice signal as an electrical signal Encoding for converting the audio signal of the microphone 108 and the analog form output from the microphone 108 into a digital signal and converting the converted digital signal into a decoded pulse data (ADPCM ADaptive Pulse Code Modulation). Memory 109, which consists of a signal processor 107, an EPROM, a ROM, and a RAM, stores parameters for various operations, and particularly stores a message corresponding to a detected error in order to carry out the present invention. Controlled by the LCD (Liquid Crystal Display) display unit 110 and the central processing unit 102 for display to generate a high frequency signal of 1.8GHz, and transmits the signal processing to mix and transmit the ADPCM data and the generated 1.8GHz Processing unit 111, receiving processing unit 113 for receiving processing so that the original signal can be extracted from the received 1.8GHz signal, the transmission processing unit (1) The signal output from 11 is propagated to the air, and the signal propagated from the fixed station is received and output to the receiving processor 113 for an antenna 112.

2 is a flowchart of a method for outputting a disconnection factor through a call of a portable terminal according to the present invention.

Next, the operation of one embodiment according to the present invention will be described in detail with reference to FIGS. 1 and 2.

If a call path connection request control signal is applied to attempt a call from the user through the key input unit 101, the central processing unit 102 controls the transmission processing unit 111 and the reception processing unit 113 in the portable terminal in step 201. Attempts to establish a call over the antenna 112. However, if the call path is not connected despite the attempt to connect to the call path of the central processing unit 102, the central processing unit 102 proceeds to step 202 and is applied to the fixed station through the antenna 112 and the receiving processing unit 113 ( Check whether a received signal (not shown) is detected.

If the reception signal of the fixed station (not shown) is not detected as a result of the check in step 202, the central processing unit 102 proceeds to step 203, such as 'no stationary station received signal' stored in the memory unit 107. After reading the message, the flow proceeds to step 204. However, if there is a check signal from the fixed station (not shown) in step 202, the process proceeds directly to step 204.

In step 204, the central processing unit 102 checks whether there is a time slot available in the registered fixed station (not shown). As a result of the check, if there is no time slot, the process proceeds to step 205 where a message such as 'time slot is in use' is read from the memory unit 107 and the process proceeds to step 206. However, if there is a time slot in step 204, the process proceeds directly to step 206.

In step 206, the central processing unit 102 checks whether a collision with another terminal has occurred. In this case, the collision with other terminals may occur when trying to access each other at the same time in the same area. As a result of the check, if a collision occurs, the process proceeds to step 207, after reading a message such as 'collision occurrence' from the memory unit 107, and proceeding to step 208. However, if there is no collision in step 206, the process proceeds directly to step 208.

In operation 208, the central processing unit 102 checks whether a call error rate due to ambient noise is greater than or equal to a reference value. As a result of the check, if the error rate is greater than or equal to the reference value, the process proceeds to step 209, after reading a message such as 'error overrun' from the memory unit 107, and proceeding to step 210. However, if the error rate is not higher than the reference value in step 208, the process proceeds directly to step 210.

In operation 210, an error message read from the memory unit 107 may be output for the user to recognize. That is, the decoding signal processor 105 and the speaker 106 are controlled to output a voice signal corresponding to the read message or the LCD screen display 110 to display the above-mentioned message.

On the other hand, when the check path of step 201 is connected to the call path to the portable terminal proceeds to step 211. In step 211, the central processing unit 102 controls the call path requested by the corresponding subscriber to proceed, and when the call ends, proceeds to step 213 through step 212, releases the connection to the call, and then ends the operation. .

As described above, the present invention has an advantage of allowing a user to take action on a non-connection cause by informing the user of the non-connection cause through a portable terminal used in a wireless telephone network system when the call is not connected.

Although the present invention has been described as the above-described embodiment, those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification but should be defined by the claims.
