BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a public wireless communication system, and more particularly, to a system for providing a call service between communication devices through a digital wireless public telephone network called a telepoint and a control method thereof.

In recent years, with the development of mobile communication technology, consumer demand for personal mobile communication devices such as cordless phones, portable phones, pagers, car phones, and the like is increasing day by day. Among these mobile communication devices, in particular, wireless telephones are inexpensive and practical compared to other mobile communication devices, and they are currently widely used by consumers because they prefer to purchase them.

Currently, cordless telephones are connected to the wired telephone lines of the existing public switched network (PSTN) and adopt analog methods. Since these cordless phones do not form a separate network, each handset can be used for anything but its own private base station. In addition, by installing a lot of cordless phones in each home and office, there is a lot of interference and noise when using a cordless phone, and there is a risk of wiretap.

In order to overcome these problems and provide a call service in a new way, the present invention provides a wireless telephone call within a predetermined radius (radius of several hundred meters) in which a telepoint is installed through a digital wireless public telephone network called a telepoint. To implement the next generation of digital cordless phones.

Accordingly, an object of the present invention is to implement a wireless public telephone network base station that performs digital wireless communication for a wireless telephone.

In addition, the switching unit 60 is composed of various switches necessary for connection with the public switching network 6 and connection with the modem 42.

FIG. 7 is a diagram illustrating a detailed block configuration of the wireless transceiver 400 of FIG. 3.

The wireless transceiver 400 transmits a baseband signal to a high frequency signal (RF) of several hundred megahertz (MHZ) band, for example, a high frequency signal (RF) of 800 MHZ or 900 MHZ band and transmits the signal. It receives and processes (RF) and produces the necessary baseband signal. The wireless transmitter / receiver unit 400 may be connected to the antenna ANT by itself, and may be connected to each other. The coupling distributor 450, which is a connection device for connecting the N wireless transceivers 400 to one antenna ANT, will be described later. It may also be used in conjunction with FIG. 8.

Referring to FIG. 7, the high frequency signal RF input from the antenna ANT or the coupling divider 450 passes through the filter 50, which is a circuit for passing only a specific frequency component, to remove unnecessary signals. Since the filter 50 is bidirectional, it has the same performance with respect to the reception signal from the antenna ANT and the transmission signal to the antenna ANT. The communication system of the present system is a time division duplex (TDD), which divides the same carrier in time and alternately transmits and receives every few milliseconds. For example, repeat the reception alternately for 1ms.

In FIG. 7, the hand-holding switch 52 is used as a circuit for alternately switching between the reception circuit unit 410 starting with the low noise amplifier 54 and the transmission circuit unit 420 starting with the power amplifier 72.

First, the configuration and operation of the reception circuit unit 410 will be described with reference to FIG. 7.

The reception circuit unit 410 includes a low noise amplifier 54, a reference signal generator 66, a first frequency synthesizer 56, a mixer 58, an intermediate frequency amplifier 60, a demodulator 62, and a data discriminator ( 64).

The low noise amplifier 54 is an amplifier having a predetermined gain in a low noise state. The low noise amplifier 54 amplifies and outputs a high frequency signal RF input through the transmission switching switch 52 with a predetermined amplification coefficient. Since the noise characteristic of the receiving circuit unit 410 is mostly left and right by the amplifier located at the front end, it is preferable that the amplifier necessarily uses a circuit having low noise characteristics (or possible). The mixer 58 outputs an intermediate frequency signal having a frequency equal to the frequency difference between the two signals by multiplying the high frequency signal output from the low noise amplifier 54 and the first frequency synthesizer 56 generated by the first frequency synthesizer 56. . The intermediate frequency amplifier 60 serves to amplify the signal obtained by the mixer 58 with a certain gain. The demodulator 62 extracts the baseband signal from the intermediate frequency signal output from the intermediate frequency amplifier 60 by a predetermined frequency modulation (FM) and outputs the demodulated analog signal. The demodulator 62 of the present invention extracts a baseband signal from a signal modulated by a Gaussian Filtered Minimum Shift Keying (GMSK) method, which is one of frequency modulation methods. The data discriminator 64 is a circuit which recovers a digital signal from the demodulated analog signal output from the demodulator 62, and this digital signal becomes reception data.

In the present invention, the wireless transmitter / receiver 400 may occupy a maximum bandwidth of 4MHZ due to the presence of 40 channels having a carrier frequency of 100KHZ, and the wireless connection shown in FIG. 3 is used to select a desired channel. The device 300 must receive the predetermined control signal from the radio controller 94 (which will be described in detail with FIG. 9 below) to adjust the first and second frequency synthesizers 56 and 70. The first frequency synthesizer 56 is used for reception, and the second frequency synthesizer 70 is used for transmission. The reference signal generator 66 which provides a reference signal to the first frequency synthesizer 56 and the second frequency synthesizer 70 is commonly used for two synthesizers.

Next, the configuration and operation of the transmission circuit unit 420 of the wireless transmission / reception unit 400 of FIG. 7 will be described.

The transmission circuit unit 420 includes a transmission filter 68 for filtering the digital transmission data output from the wireless access device 300 of FIG. 3 into an analog signal, a reference signal generator 66 for generating a reference signal, and a reference signal. A second frequency synthesizer 70 for synthesizing the transmission signal from the reference signal of the generator 66 and the analog signal of the transmission filter 68, and a power amplifier 72 for amplifying the transmission data to an output strength suitable for transmission. do.

The operation of the transmitting circuit section 420 will be described based on the above configuration.

The transmitting circuit unit 420 filters the digital transmission data into a transmission filter 68 having characteristics of a Gaussian filter, converts the digital transmission data into an analog signal, and directly outputs the analog signal to the second frequency synthesizer 70. The signal synthesized and modulated by the second frequency synthesizer 70 becomes a signal having a frequency shift of several 10 KHZ up and down at the center frequency of the carrier wave. The power amplifier 72 raises the level of the signal so that the signal output from the second frequency synthesizer 70 has an output strength for transmission. The signal output from the power amplifier 72 is transmitted to the antenna ANT or the coupling distributor 450 through the transmission / reception switching switch 52 and the filter 50. Reference numeral 74 denotes a wireless signal terminal connecting the filter 50 and the coupling divider 74 shown in FIG.

A coupling divider 450, which is a connecting device for allowing one antenna ANT to be shared by the N wireless transceivers 400, is connected to the N wireless transmitters and receivers 400 as shown in FIG. .

The coupling distributor 450 shown in FIG. 8 includes a port 68 composed of a transmission / reception switching switch corresponding to the number of wireless transmission / reception units 400 and a signal input from an antenna ANT. The splitter 80 is divided into the port 86 connected to the 400, and the combiner 82 which combines several signals from the port 86 into a single signal.

The port 86 is composed of N transmission / reception switching switches, that is, transmission / reception switching switch 1 to transmission / reception switching switch N. Each transmit / receive switch corresponds to each port. Each port is controlled by a radio signal input and output to the radio signal terminal 74 connected to the filter 50 by the radio transmitter / receiver 400, the control signal terminal 76 for controlling transmission and reception, and the radio signal terminal 74. It has two terminals 78 and 79 to be connected to the divider 80 or the combiner 82 according to the logic value of the control signal input through the signal terminal 78. That is, when the control signal is logic "1", the radio signal is output to the combiner 82, and when the control signal is logic "0", the signal input from the divider 80 is connected to the radio signal terminal 74.

The splitter 80 divides the signal input from the antenna ANT into each port of the port 86 connected to the corresponding wireless transceiver 400, and the combiner 82 receives a plurality of signals from the port 86. Combines the signals into a single signal.

The signal added by the combiner 82 passes through the attenuator 84. In order to compensate for this difference, the attenuator 84 uses a cable because the loss varies depending on the length of the circulator 88 and the antenna cable. Adjust the output of the combiner 82 so that a constant output is always radiated from the antenna ANT in accordance with the loss.

The circulator 88 attenuates the transmission output as an irreversible coupling circuit while preventing the large output signal passing through the combiner 82 and the attenuator 84 from passing over to the divider 80 which processes the weak received signal. At 84, only the antenna ANT direction is adjusted so that the received signal is directed from the antenna ANT to the distributor 80 only.

Next, the wireless access device 300 shown in FIG. 3 will be described in more detail with reference to FIG. 9 is a detailed block diagram of the wireless access device 300.

The wireless access device 300 includes a memory 90, a system interface 92, a wireless control unit 94, a CAI CT2 baseband unit 96, and a wireless interface unit 98.

Referring to the operation of the radio access device 300, the radio controller 94 controls the overall operation of the radio access device 300, the memory 90 is the data and call-related data necessary for the operation of the radio access device 300 Save it. The system interface 92 transmits / receives a signal necessary for the control of the radio access device 300 and call request data from the radio portable device (4 in FIG. 1) with the control device 500. The CAI CT2 baseband unit 96 supports the signal layers 1 and 2 of the CAI CT2 standard protocol as shown in FIG. 2, and converts the voice PCM data coming through the system interface 92 into ADRCM data. And converts the voice ADPCM data coming through the air interface unit 98 into PCM data. In addition, the wireless interface unit 98 interfaces control signals between the wireless controller 94 and the wireless transmitter / receiver 400 and transmits and receives predetermined data to or from the wireless portable apparatus 4.

The telepoint base station 2 as described above is a digital communication system. By implementing a wireless public telephone network base station, that is, a telepoint base station 2, which performs digital wireless communication for a wireless telephone (wireless portable device), the telepoint base station 2 performs a digital wireless call service.

Hereinafter, the control process for performing the digital wireless call service by the telepoint base station 2 described with reference to FIGS. 1 to 9 will be described in more detail.

The telepoint base station 2 constructs a call path through a wireless link setting operation and a call setting operation between the wireless access device 300 and the wireless portable device 4 when a call request is generated from the wireless portable device 4. Information generated after the end and information generated during the operation of the base station is maintained by the operation of transmitting and receiving to the base station management system (8).

23 shows a form diagram of the information elements configured in the transmission / reception control operation between the telepoint base station 2, the wireless portable apparatus 4, and the base station management system 8. As shown in FIG.

Referring to Figure 10 will be described in more detail the radio link setting operation process.

When a user requests a call through the wireless portable device 4, the CAI protocol signal layer 1 (Layer 1) shown in FIG. In the present invention, 40 channels are used as an example) to select an empty channel to establish a radio link, and link request data generated by the wireless portable device 4, that is, signal frames 1,2 and 3 (MUX 3). , 2, 1 is transmitted to the wireless access point 300 of the telepoint base station 2. (1000 steps in FIG. 10 (a))

Meanwhile, the wireless controller 94 of the wireless access point 300 in the various telepoint base stations 2 transmits the status indication information element of FIG. 23 (a) provided from the control device 500 through the system interface 92. It stores in the memory 90. The state indication information elements stored in the memory 90 are information designated as control, standby, and closed states. It can be seen from FIG. 23 (a) that the state indication information element has a state indication ID, a connection state state, and an unused area.

The wireless controller 94 of the wireless access device 300 determines whether the state indication information element stored in the memory 90 is in a control state in step 1002 of FIG. 10B. If it is not in the control state, that is, the standby state or the closed state in step 1002, the wireless control unit 94 continues to check the state indication information element stored in the memory (90). Here, the standby state is a state in which the air interface unit 98 of the radio access device 300 does not scan a channel, and in the closed state, the radio control unit 94 blocks channel scanning due to an abnormality of the radio access device 300. It means state.

The wireless access device 300 in which the status indication information element is in a control state is configured as shown in FIG. 23 (b) through the system interface 92 to indicate the use state of a channel being used when other surrounding wireless access devices are designated. Use channel information element of the control unit 500 is specified. Therefore, the radio controller 94 of the radio access device 98 generates a predetermined random number (the embodiment of the present invention is 1 to 40) and stores it in a channel not used by other radio access devices, that is, the memory 90. Check whether the channel is not included in the used channel information. If it is determined that the channel is not used, the wireless controller 601 selects the channel in step 1004. When the air interface unit 98 tunes to the selected channel in response to step 1004, the air controller 94 then measures the electric field strength Rssi through the air interface unit 98 for a predetermined time (1006 in FIG. 10). step)

In step 1006, if the measured field strength value Rssi is less than the specific level value A stored in the memory 90, the selected channel is transferred from the wireless portable device 4 to the wireless interface unit 98. Considering that there is no carrier, the wireless controller 94 returns to step 1004 to select an unused channel again. The specific level value A may be changed by the installation environment of the wireless access device 300 and the transmission output control through the wireless interface unit 98 from the wireless control unit 94.

If the specific level value A is equal to or greater than 100 in step 1008, the wireless controller 94 detects the channel marker data (CHMP: Channel Marker bit Pattern) for a predetermined time in the CAI CT2 base band unit 96 by performing step 1010. The CAI CT2 base band section 96 is controlled to wait until. The CHMP is information transmitted from the wireless portable device 4. If the CAI CT2 base band unit 96 does not detect the CHMP for a predetermined time, the wireless control unit 94 returns to step 1004 and selects an unused channel again.

When the CAI CT2 baseband unit 96 detects CHMP in step 1010, the wireless controller 94 waits for the synchronization indication data (SYNCD: Sychronizationword for D Channel) to be detected in step 1012. The base band section 96 is controlled. The SYNCD is preferably set to be located at the beginning of the basic information element type and immediately after the CHMP.

If the SYNCD is not detected in step 1012, the wireless controller 94 returns to step 1004 and repeats the above operation. When the CAI CT2 base band unit 96 detects the SYNCD in step 1012, the following information is received and a cyclic redundancy check (CRC) error is detected. In step 1014, if the received data is a CRC error, the wireless controller 94 1004. Returning to the step, the above operation is repeatedly performed.

If the CAI CT2 base band unit 96 of the wireless access device 300 detects the normality of the data CRC received in step 1014, the wireless controller 94 analyzes the received data in step 1016. According to the information element of the analyzed data, the wireless control unit 94 transmits the information element to the wireless portable apparatus 4 through the wireless interface unit 98 or to the control apparatus 500 via the system interface 92. (Steps 1018-1036)

More specifically, if the data analyzed in step 1016 is a link request (LINKREQUEST), the wireless controller 94 transmits " LINK_GRANT " to the wireless portable device 4 through the wireless interface unit 98 for a predetermined time specified in the CAI. (Steps 1018 to 1020) When the wireless portable apparatus 4 receives "LINK_GRANT" from the wireless interface unit 98 of the wireless access device 300, it transmits "ID_OK" and responds with "SABM (Set). Asynchronous Blanced Mode) "is transmitted to the wireless access device 300 continuously. Accordingly, when the wireless controller 94 of the wireless access device 300 receives "ID_OK" through the wireless interface 92, it transmits "ID_OK" in response to this, and sets an ID exchange, that is, a handshake timer. If the ID_OK is not received, the wireless controller 94 checks whether the set ID exchange timer is timed out and transmits "ID_LOST" if it is timed out. (Step 1026 to 1028) If the transmission of the "ID_OST" is more than a predetermined number of times, for example, more than three times, the wireless controller 94 performs the link reset mode. (Step 1030) In addition, the wireless controller 94 is a wireless portable device In response to detecting "SABM" from the data received from (4), "SABM_ACK" is sent to the wireless portable device 4 in response thereto, and the link setting information element of the form shown in FIG.

When the radio link is established to the control device 500 in step 1036, the control device 500 checks whether the link setting information element is received from the radio access device 300, and transitions the call setting step in response to the reception. . This corresponds to steps 1038 to 1040 of FIG. When the wireless link is established, the CAI CT2 baseband unit 96 is controlled by the wireless controller 94 to perform handshaking for the wireless portable device 4 and the wireless access device 300 to maintain the wireless link. Do this.

Handshaking will exchange IDs at regular time intervals specified in the CAI. If no valid ID is received within this time, "ID_LOST" is sent. If a valid ID is received, "ID_OK" is sent. This corresponds to steps 1022 to 1030. When the radio controller 94 repeats "ID_LOST" three or more times, it is regarded as a link setup failure and repeats again from step 1004 of FIG. 10 (b) to reset the link.

The control apparatus 500 designates the state indication information element and the use channel information element shown in FIGS. 23 (a) and 23 (b), respectively, in order to control the wireless access device 300. This information element is an internal information element of the control device 500 and the wireless access device 300, the basic form of which is shown in FIG. 23 (d).

Among the use channel information elements, the use channel information is composed of 1 to 40 channels, and up to seven channel information are inputted and wireless. It is transmitted to the connection device 300.

The link setting information element illustrated in FIG. 23 (c) is information transmitted by the wireless control unit 94 of the wireless access device 300 to the control device 500 through the system interface 92 when the wireless link is established. An element includes a wireless portable device ID for which a wireless link is set, a service ID, a use channel, that is, a current channel number.

In FIG. 10 (c), when the control device 500 transitions to the call setup step, the wireless handheld device 4 and the control device (in FIGS. 11 and 12 are separated between the wireless handheld device 4 and the control device 500). The call setup operation will be described from the state in which layer 2 between 500 is established.

In a state in which a layer 2 connection is established, the wireless portable apparatus 4 transmits a " TERM_CAP (Terminal Capabilities Information Element) " representing the capability of the wireless portable apparatus and a " Feature Activation Information Element " Transmit in step 1100. These messages are analyzed by the radio controller 94 via the air interface unit 98 and the CAI CT2 base band unit 96 of the radio access device 300 and then transmitted to the controller 500 through the system interface 92. do. Since the path of the other message received from the wireless portable device 4 to the control device 500 is received through the routine as described above, a description of the received routine will be omitted.

On the other hand, when the layer 2 connection is established, the control device 500 transmits a " BAS_CAP (Base Capabilities Information Element) " message indicating the processing capability of the telepoint base station 2 through the system interface 92. Forward this message to 300. The wireless access device 300 receiving the "BAS_CAP (Base Capabilities Information Element)" message passes through the CAI CT2 base band unit 96 and the wireless interface unit 98 under the control of the wireless control unit 94. 4) will send this message. This corresponds to step 1102 of FIG. Since other message paths for transmitting a message from the control device 500 of the telepoint base station 2 to the wireless portable device 4 are transmitted through the routine as described above, a description of the subsequent message paths is omitted. Shall be.

The controller 500 detects the message " TERM_CAP " transmitted from the wireless portable device 4 in step 1100 and the " BAS_CAP " message transmitted from the control device 500 in step 1102. The received wireless portable device 4 stores the processing power of the other party in its memory (steps 1104 through 1110). The processing power of the other party stored in the memory is then used for the service.

After detecting the "FA" message transmitted from the wireless portable apparatus 4 in step 1100 of FIG. 11 in step 1112 of FIG. 12 and receiving the control device 500, the control device 500 receives a "Feature Indication Information Element" in response. The message is sent to the wireless portable device 4 in step 1114. In addition, a 32-bit random number is generated in step 1116 for authentication of the wireless portable apparatus 4. The control device 500 responsive to step 1116 transmits an "AUTH_REQ (Authentication Request Information Element)" message including the generated 32-bit random number to the wireless portable device 4 in step 1118, and then the wireless portable device ( Wait for "AUTH_RES (Authentication Response Information Element)" response from 4).

On the other hand, after detecting the "AUTH_REQ" message transmitted from the telepoint base station 2 in step 1118 of FIG. 12 in step 1120 of FIG. 11, the wireless portable device 4 receiving the received message is a key stored in its memory area. With the (KEY) value and the 32-bit random number stored in the "AUTH_REQ" message, the 'f' algorithm is performed to get the result "CKEY (Encrypted KEY)". This corresponds to step 1122 of FIG. It should be noted that the 'f' algorithm was designed in the UK to authenticate CT2 CAI wireless handheld devices and that the CT2 CAI wireless handheld device 4 or telepoint base station 2 should be able to perform this algorithm. do.

To send).

The control device 500, which has received the " AUTH_RES " message transmitted from the wireless portable device 4 in step 1124 in step 1126 of FIG. 12, from the radio access device 300 in establishing the radio link described above with FIG. Obtained by performing the 'f' algorithm using the received data of the wireless portable device 4 (MIC: Manufacture Identity Code, HIC: Handset identity Code) and ZAP, TRD, OPSIC, and TCOS included in the “AUTH_RES” message. The value and the 32-bit random number generated by the control device 500 perform an 'f' algorithm to obtain a result value "E-CKEY (Expeced CKEY)". This is true at step 1128 of FIG. The 'f' algorithm can be independently implemented in a company operating the telepoint base station 2. The key value of the above-described wireless portable device 4 is obtained by performing the 'f' algorithm in step 1128, and the value stored in the memory of the wireless portable device 4 at the time of registering the wireless portable device 4. do.

In step 1130, the control device 500 that performs step 1128 compares the value of the "CKEY" stored in the message "AUTH_RES" with the value of its calculated "E-CKEY". Perform the authentication procedure. If the "CKEY" value and the "E-CKEY" value are the same in step 1130, in response to this, the control device 500 stores each area value included in the "AUTH_RES" message for use in the service in the memory 12. Save it for future use. This corresponds to step 1132 of FIG. If the CKEY value and the E-CKEY value do not match in step 1130, the control device 500 performs step 1158 to send an "INIT (Initialisation Information Element)" message to the wireless portable device 4 and terminate the service. do.

In order to connect the B channel, the control apparatus 500 performing the step 1132 transmits a "Channel Control Information Element (CC)" message to the wireless portable apparatus 4 in step 1134. Wait for the "CC" message acknowledgment.

The " CC " message is transmitted to the wireless portable device 4 once more by setting the parameter value to 0, and upon receipt of the layer 2 confirmation thereof, the parameter value is set to 2 and transmitted again to the wireless portable device 4 again. Do. Transmission of the " CC " message corresponds to step 1134 of FIG.

Upon receiving the layer 2 confirmation from the wireless portable device 4 for the second " CC " message in step 1137, the control device 500 responds in response to the language type of the voice guidance that the wireless portable device 4 wishes to receive. In step 1138, the wireless portable device 4 transmits the message " PAR_REQ " (type = 2). The control device 500 then waits for the reception of the "Parameter Response Information Element (PAR_RES)" message transmitted from the wireless portable device 4.

When the wireless portable apparatus 4 receives a "PAR_RES (Parameter Response Information Element)" message from the control apparatus 500 (step 1139), the wireless portable apparatus 4 stores the language desired to be provided by the wireless portable apparatus 4. Message is sent to the control device 500 (step 1140).

If the control device 500 in response to step 1140 does not receive the "PAR_RES" message transmitted from the wireless portable device 4 until the "PAR_RES" message waiting timer expires (steps 1141-1414), the control device 500 In step 1144, the language type of the voice guidance to be provided is determined as a default value.

When the control apparatus 500 receives the "PAR_RES" message from the wireless portable apparatus 4 in step 1140, the control apparatus 500 provides the language type of the voice guidance to be provided to the wireless portable apparatus 4 with the contents of the "PAR_RES" message. (Step 1146)

Thereafter, the control device 500 stores a hot list in which the TRD value, which is an account number of the wireless portable device 4 stored in the memory 12 in step 1132 of FIG. 12, is stored on the memory 12. HOT-LIST) is checked in step 1148. If there is an account number (TRD: Terminal Registration Data) of the wireless portable device 4 on the hot list HOT to LIST, whether the corresponding prohibition is performed (step 1150) or zapping (step 1152). If it is determined that the call is prohibited, a voice (including the type of language) indicating that the call is in a call prohibited state stored in the memory 28 of the voice processing apparatus 200 is selected and the voice guidance is wirelessly connected to the voice message processing unit 30. Through the device interface unit 32 to be transmitted to the wireless portable device (4). This is true at step 1154 of FIG. If the voice guidance transmitted in step 1154 is not cut off by the wireless portable apparatus 4 until the voice guidance transmission timer expires (step 1156), when the timer ends, the control apparatus 500 responds wirelessly. Send an "INIT" message to device 4 and terminate the service (step 1158).

In the determination of step 1152 of FIG. 12, when a Zapping object is to be mapped on the HOT-LIST, the control device 500 sets the "Increment ZAP field control bit" area to 1. Transmits the "AUTH_REQ" message set to the wireless portable apparatus 4 (step 1158), the wireless portable apparatus 4 is zipped and stored in the memory 28 of the voice processing apparatus 200. A voice (including the type of language) indicating the (Zapping) state is selected so that this voice guide is transmitted to the wireless portable device 4 through the voice message processing unit 30 and the wireless access device interface unit 32. The voice guidance transmission is performed until the set voice guidance transmission timer ends (step 1162).

After transmitting the "AUTH_REQ" message in step 1158 to the wireless portable device 4, the control device 500 receives the "AUTH_RES" message from the wireless mobile device 4 until the set "AUTH_RES" receiver-to-timer ends. Check in When receiving the "AUTH_RES" message in step 1164, if the wireless portable device 4 does not disconnect the call, the control device 500 transmits the voice guidance until the set voice guidance timer ends (steps 1160 and 1162) and "INIT". Service is terminated by performing step 1158 of sending the message.

On the other hand, if the "AUTH_RES" message is not received until the end of the set "AUTH_RES" receiver-to-timer in step 1164, the flow returns to step 1158 described above and transmits the "AUTH_REQ" message to the wireless portable device 4 again.

A process not described in the determining step of step 1148 of FIG. 12 will be described later.

If the wireless mobile device account number TRO does not exist on the hot list in step 1148, the control device 500 inputs a dial input stored in the memory 28 of the voice processing device 200. Select the requesting voice (including the type of language) so that the voice guidance is transmitted to the wireless portable device 4 through the voice message processing unit 30 and the wireless interface unit 32 shown in FIG. (Step 1170), awaiting reception of the "KP (Keypad Information Element)" message carrying the dial data input to the wireless portable apparatus 4;

In response to step 1170, the wireless portable apparatus 4 receives a "voice prompt requesting a dial input" from the control apparatus 500 in step 1172. Is transmitted to the control device 500 in step 1174.

Whenever the control device 500 receives the "KP" message in response to step 1174, the control device 500 displays the display by referring to the processing capacity of the wireless portable device 4 previously stored in the memory 12. The capable portable portable device 4 transmits a "Display Information Element" message so that the dial data entered by the portable portable device 4 can be displayed (steps 1176 and 1178). The control device 500 for receiving a message from the wireless portable device 4 stores the received dial data in the memory 12, previously downloaded from the telepoint base station management system 8, and stored in the memory 12. Call processing is performed with reference to a dial analysis database (stored separately for each grade). (1180, 1182 steps)

If the control device 500, which responds to step 1174 of FIG. 11, fails to receive the "KP" message from the wireless portable device 4 until the set "KP" message reception waiting timer expires (step 1186), the voice processing is performed. The voice guidance (including the type of language) indicating that the dial input stored in the memory 28 of the device 200 is late is selected so that the voice guidance is performed by the voice message processing unit 30 and the radio interface unit 32. The voice guidance is repeatedly transmitted unless the mobile terminal is disconnected until the voice guidance transmission timer expires (step 1188). 500 transmits an " INIT " message to the wireless portable device 4 and ends the service (step 1158).

On the other hand, when the control device 500 analyzes the dial input from the wireless portable device 4 in step 1182 of FIG. 12, if the call needs to be centralized to the base station management system 8 (step 1194), the control device controller ( 16 accesses the modem 42 of the wired access device 100 through the modem interface 20 and connects the telephone network to the base station management system 8 using the AT command (step 1196). When the link between the modem 42 of the device 100 and the modem of the base station management system 8 is established (step 1198), the control device 500 determines the base station number and the type of call of the wireless portable device 4. Send to management system 8 to inquire how to proceed with call processing (step 1200).

In response to step 1200, the control device 500 that has received the predetermined result from the base station management system 8 in step 1202 proceeds in the same manner as the hot-list process when the call prohibition is Zapping. . That is, if the call is prohibited (checked in step 1204), a voice guidance indicating a call prohibited state, which is the aforementioned step 1154, is transmitted. do.

If the call is not prohibited or zapping in steps 1204 and 1206, the control device 500 seizes and dials the public switched network (PSTN) of the wired access device 100, and if the other party answers, the call is answered. (1208, step 1210)

As a process not described in the judgment in steps 1194 and 1196 of FIG. 12, if the dial analysis result is not a call requiring central authorization or a prohibited call, the call is put in a call state when the other party answers as a result of the wired dialing. Step 1210)

Meanwhile, in step 1174 of FIG. 11, the wireless portable device 4 waiting for the other party's response after transmitting the “KP” message carrying the telephone number to which the user wants to talk, is responded to by the other party with the wired dialing.
