BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a portable terminal adopting a digital European Communica Tion (DECT) method in a wireless telephone network system, and more particularly, to a method for controlling continuous communication through a portable terminal. .

In general, a wireless telephone network system wirelessly establishes a network between a fixed station (or a base station, hereinafter referred to as a fixed station) and a portable terminal (or mobile phone) to transmit and receive data. A portable terminal employing a DECT method for transmitting and receiving digital data is a type of mobile phone used in such a wireless telephone network system.

When a portable terminal attempts to connect with another terminal continuously, when a call is terminated with one terminal, the bearer of the MAC (Medim Access Control, hereinafter referred to as MAC) layer frame is recovered. After inputting a number of another terminal to be connected as a new number, a new call is made by reconnecting to the MAC layer, DLC (DLC) layer, and network layer. At this time, if there are many connection attempts in the same fixed station, the time slot is used by another call waiter during a period of attempting to connect with another terminal after the call with one terminal is difficult, so it is difficult to immediately reconnect. This is because the other call waiter waits only for the end of use of the time slot of the existing caller and attempts to connect immediately when the slot is not used. Therefore, when attempting additional access, not only have to wait for the use of existing timeslot users as in the first access, but also have to overcome the competition with other access attempts.

Accordingly, an object of the present invention is to provide a method for controlling a mobile telephone network system to continuously proceed with another terminal having a new number without losing the right to use a connected time slot when a continuous call is made through the terminal.

In order to achieve the above object, a method according to the present invention is a method for controlling a continuous call through a portable terminal in a wireless telephone network system that forms a network with a fixed station and a portable terminal: A portable terminal is connected by an operator in a standby mode. If the request control command is authorized, accessing a call path to access a predetermined terminal; performing a call when the access is completed through the access process; When the call execution process is completed, checking whether the continuous call mode is set; Delaying the release of the call between the fixed station and the predetermined terminal when the continuous call mode is set by the checking process; Inputting a number of a terminal for a new connection; If a number of a terminal for new access is input through an input process, releasing a call path between a fixed station and a predetermined terminal; Performing a call connecting a call corresponding to a newly input number when the call is released by the call release; If the continuous call mode is not set in the continuous call mode check process, the method includes releasing the call path to terminate the call.

Next, an embodiment according to the present invention will be described with reference to the accompanying drawings.

1 is a schematic diagram of a deck-type portable terminal used in a wireless telephone network system, the power supply unit 101 for supplying power of a terminal, a key for applying a control command of an operator, and in particular, a control command for a continuous call. The input unit 102, the central processing unit 103 for controlling all functions of the terminal, the microphone 106 for converting and outputting the operator's voice signal into an electrical analog signal and the microphone controlled by the central controller 103 The coded signal processing unit 107 and the central controller 103 control the received coded speech signal to be changed into ADPCM (ADaptive Pulse Code Modulation) data used in the decect output from the 106. In the decoded signal processing unit 104 and the decoded signal processing unit 104 which converts the PCM data and performs decoded signal processing so as to convert into an analog signal. A memory for storing the parameters for various operations of the terminal is configured to include a speaker 105, EEPROM (Electrically Erasable ROM) and ROM and RAM for outputting the output voice signal as a voice signal that can be recognized by the terminal operator ( 108), a transmission processor 109 for generating a high frequency signal of 1.8 GHz, and generating a high frequency signal and a synthesized voice signal encoded by ADPCM, and amplifying the synthesized signal, and a low noise amplification and intermediate for the received signal. Receive processing unit 111, which receives the original signal transmitted from the frequency conversion process and the intermediate frequency and performs the receiving process, propagates the data output from the transmitting processing unit 109 in the air, and receives the received data in the air. 111 to an antenna 110 for outputting.

2 is a flowchart illustrating a method for controlling a continuous call according to the present invention in a deck-type portable terminal configured as shown in FIG.

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

When the terminal is powered on by the terminal operator in step 201, the power supply unit 101 supplies power to the central processing unit 103. Accordingly, the central processing unit 103 controls the power supply to the peripheral processing circuits. In operation 202, the initial value of each hardware in the terminal stored in the memory 108 is read, and each hardware in the terminal is initialized using the read initial value.

In step 203, the station is selected closest to the one where the terminal is located. Here, the selection of the adjacent fixed station is to examine the received electric field strength of all 10 radio channels from radio channels 0 to 9 in the same manner as before, and select the fixed station which transmits the strongest radio signal among them.

When the fixed station is selected as described above, the process proceeds to step 204 and a process of registering with the selected fixed station is performed. The registration process also performs a registration procedure after checking whether the time slots in a fixed station have been previously selected to see if there are any unused time slots. The operator checks whether a PAGING signal is received or whether a connection request control command is issued by the operator.

First, in step 205, it is checked whether a paging signal exists.

As a result of the check, if there is a paging signal, the connection is requested from another terminal, and the flow proceeds to step 206 to connect each layer for a call, and release the connection of each layer connected by any one call disconnect control. do.

In step 207, the terminal inspects the state of the terminal. First, in step 207, the battery is used as a power supply, and checks whether there is an abnormality, and if an error occurs, a warning process is performed so that an operator can recognize it. In step 209, a new station is selected. The registration process is also performed in the same manner as performed in step 204.

When the registration process is completed in the fixed station, the process proceeds to step 210 to determine whether the continuous call mode is set by the operator. As a result of the determination, if the continuous call mode is set, the process proceeds to step 211, in which the call mode of the terminal is set to the continuous call mode; The process proceeds to step 205 after setting the single call mode.

On the other hand, if the paging signal does not exist in step 205, the flow proceeds to step 213 to determine whether the connection request signal generated by the terminal operator. As a result of the determination, when the access request signal is generated, the process proceeds to step 214 and as in step 206, access is made to a call for a call. At this time, the call connection is established in the order of first connecting the MAN (Medium Accdess Control) layer, then connecting the DLC (Data Link Control) layer and the network (NETWORK) layer. When the call path is connected in this manner, the process proceeds to step 215 where the operator talks to the operator of the desired terminal. In step 216, if the network release signal is applied from either of the key input units 102 to terminate the call, the process proceeds to step 217 to determine whether the call is in a continuous call mode. The continuous call mode is set by a control command applied by the operator through the key input unit 102.

If it is determined in step 217 that the continuous call mode is set, the terminal proceeds to step 218 to transmit a BEARER_REQUEST signal to the fixed station to maintain the MAC layer connection. That is, by transmitting the idle frame of the MAC layer frame to ensure the time slot that the call was performed. As a result, the terminal and the fixed station suspend the disconnection process for the call performed in step 215. In operation 219, the terminal inputs the number of the terminal to which the call is to be made. In operation 220, it is determined whether the number input is completed. If the input is completed, the operation of disconnection, which is reserved for performing operations 217 to 220, is performed through operations 221 and 222. That is, in step 221, the network layer is disconnected from the terminal with which the call is completed. In step 222, the DLC layer is released. In step 223, the MAC layer is connected to the newly input number. In step 224 and step 225, the DLC layer and the network layer for the new input number are connected, and then the flow proceeds to step 215 to perform a call.

However, if the continuous call mode is not set in step 217, the process proceeds to step 226, 227, and 228 to release the call that has been made. When the release for each layer is completed, the process proceeds to step 229 and it is checked whether the power of the terminal is on. If not, the operation of the terminal is terminated. However, if the power is on, the terminal is in the standby state.

If the operator's connection request control command is not authorized in step 213, the process returns to step 207 to check the state of the terminal as described above.

In addition, when the continuous call mode is set by the operator when the first call is made, the terminal and the fixed station are connected to the BEARER and DLC layer of the MAC layer before entering the telephone number to perform the next call after the first call. After using the time delay using the time delay method, enter the new access number, and after the new access number is entered, BEARER and BLD access is skipped during the new access sequence. You can control the call. In order to maintain a bearer connection and a DLC connection, an error data reception message may be sent even in the case of normal data reception to intentionally extend the use of the timeslot.

As described above, the present invention enables the user to extend the use of the timeslot through the terminal in the wireless telephone network system so that the user can continuously talk with a plurality of terminals. There is an advantage of easy reconnection.
