The transmission / reception unit 21 includes an antenna switch for distributing transmission / reception, a frequency conversion unit having a PLL synthesizer, a modem for modulation / demodulation for connection to a communication line, and the like (none of which are shown). On the receiving side of the frequency converter, the 1.9 GHz band RF signal input from the antenna 5 via the antenna switch is mixed with a local oscillation signal of a predetermined frequency output from the PLL synthesizer to produce an IF signal near 1 MHz. Convert frequency. On the transmission side of the frequency conversion unit, the modulated wave of π / 4 shift QPSK input from the modem is mixed with the local oscillation signal output from the PLL synthesizer, frequency-converted to an RF signal of 1.9 GHz band, via an antenna switch To the antenna 5. On the receiving side of the modem, the IF signal from the frequency conversion unit is demodulated and separated into IQ data, and transferred to the communication control unit 22 as a received data string. On the transmission side of the modem, IQ data is created from the data transferred from the communication control unit 22, modulated by π / 4 shift QPSK, and output to the frequency conversion unit.
[0009]
The communication control unit 22 performs frame synchronization and slot data format processing. On the receiving side of the communication control unit 22, one slot of data is extracted from the received data sequence transferred from the modem of the transmitting / receiving unit 21 at a predetermined timing, and a synchronization signal called a unique word is extracted from this data to obtain a frame Synchronize. In addition, after descrambling the control signal and the audio signal, the control signal is transferred to the control unit 23 and the audio signal is transferred to the audio processing unit 24. On the transmission side of the communication control unit 22, a control signal is added to the audio signal transferred from the audio processing unit 24, and after scrambled, a unique word is added to create transmission data for one slot.

Further, the RAM 26 is provided with a redial memory area 266, which stores terminal data that has been previously received or transmitted and a classification to which the terminal data belongs. Since other configurations are the same as those of the first embodiment, description thereof will be omitted. In the memory card 19, as shown in FIG. 8A, data such as a name and a work phone number, which are business data, are registered. On the other hand, private data as shown in FIG. 8B is registered in the telephone directory memory 27 as in the first embodiment.
[0018]
Next, terminal data retrieval and data reading at the time of transmission in the second embodiment will be described with reference to the flowchart of FIG. When receiving a search command from the phone book button 16a of the key input unit 1, the control unit 23 proceeds to a data reading routine (step S31) and reads terminal data in the redial memory area 266 of the RAM 26 (step S32). ), It is determined whether or not there is terminal data that has been previously received or transmitted (step S33). When it is determined that there is terminal data, the classification stored with the terminal data is referred to, and the classification of the terminal data is in the telephone book memory 27 or in the memory card 19. Is determined (step S34). When it is determined that the terminal data is in the memory card 19, it is determined whether or not the memory card 19 is mounted in the slot 18 (step S35). When it is determined that the terminal data is mounted, the redial memory area 266 is determined. It is determined whether or not the memory card 19 corresponds to the classification of terminal data stored in (step S36). When it is determined that it is compatible, the business mode is set, and the memory card 19 is accessed to search for business data (step S37). On the other hand, when it is determined in step S34 that the classification of the terminal data is in the telephone directory memory 27, and when it is determined in step S35 that the memory card 19 is not installed in the slot 18, the private mode is set. Then, the telephone directory memory 27 is accessed to search for private data (step S38). In step S33, when it is determined that the terminal data that has been previously received or transmitted is not stored in the redial memory area 266, and in step S36, the memory card 19 installed in the slot 18 is stored in the redial memory area 266. When it is determined that it does not correspond to the stored terminal data classification, the mode setting is canceled and all data are searched (step S39).
[0019]
Next, the retrieved terminal data is supplied to the display unit 4 for display (step S40), and when the retrieved terminal data is larger than the maximum number of display data, a predetermined number is automatically or in response to the scroll command. Terminal data is sequentially supplied to the display unit 4. Thereafter, one of the terminal data displayed in response to the selection command is selected (step S41), and it is determined whether or not a transmission command has been received (step S42). If it is determined that the transmission command has been received, it is determined whether or not the current setting mode and the mode in the control channel established between the base stations match (step S43). If it is determined, the selected terminal data number is transmitted to the base station (step S44). On the other hand, when it is determined in step S43 that the setting mode and the mode in the control channel do not match, the mode of the control channel is set (step S45), and the terminal data of the set mode is searched (step S45).

[0020]
As described above, according to the second embodiment, terminal data that has been previously received or transmitted is read from the redial memory area 266, and the mode is set according to the classification corresponding to the terminal data. Then, the terminal data in the setting mode is searched, and when any terminal data is selected and a transmission command is received, the number of the selected terminal data is transmitted to the base station. Therefore, it is possible to quickly search for target terminal data without establishing a control channel. Also, a large number of terminal data can be registered by registering business data in the memory card 19 that is removably inserted into the main body of the PHS terminal.
[0021]
In the second embodiment, the memory card 19 is a memory dedicated to business data. However, if there is a lot of private data, the memory card 19 can be a dedicated memory for private data, or both can be mixed. It may be registered in the memory card 19. In particular, business data often includes a large amount of terminal data for each of a plurality of groups such as a customer, a supplier, a company, and the like. In such a case, a plurality of groups of business data are mixedly registered in the memory card 19. Therefore, by classifying and registering each group, reading the terminal data that has been received or transmitted last time from the redial memory area 266, and searching the classification corresponding to the terminal data, the target terminal data can be further quickly obtained. Can be searched. If a plurality of memory cards 19 are registered separately for business use and private use, the memory card 19 can be exchanged according to the use.
[0022]
In the first and second embodiments, when the control channel is established with the base station, the private mode or the business mode is set according to the base station. The mode may be set according to the mode designation. In this case, the private data can be searched for in the office, and the business data can be searched in the home.
[0023]
The classification of terminal data to be registered is not limited to private use or business use, and two or more classifications may be registered. For example, business data can be divided into data of external line partner terminals and extension line terminals. Further, when the PHS is moved to a different business office, the extension terminal data at the business office may be retrieved when retrieving the extension terminal data.
[0024]
Moreover, in the said 1st and 2nd embodiment, although the PHS terminal was taken as an example as a portable communication apparatus, it is not restricted to a PHS terminal as an object which can apply this invention, The control signal for every several different classification | category is sent to a base station And can be applied to all portable communication devices that retrieve terminal data of counterpart terminals of different classifications based on this control signal.
