Abstract

PURPOSE:To store a time of calling and incoming corresponding to a group number by providing a time storage means storing the time at which the group number stored by a group number storage means is referenced in response to the group number. CONSTITUTION:A group code coincidence subroutine (Fig. A) is provided in place of a reception group code subroutine. Optional two flag tables F1 are set to an act bit. Group codes m1-m9 stored in group code memories M1-M9 in the codes are used as queue group codes mp and groups codes m1-m9 corresponding to a high-order acti bit are used as queue group codes ms. When a group code m' is received, a program indicator PI is set to 1 or 0 because the operation of a time button is not performed. When the codes m' and mp are coincident, the program tap TP is set to 1. When the m' is coincident with the code ms, the tap PT is set to 2. When the codes mp and ms are dissident, the tap PT is set to 3. When the tap PT is not equal to 3, the branch destination is decided by the numeral of the PI and when the PI is 1, the address of the time memory is decided.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a personal radio device, and more particularly to a personal radio device that stores communication times in correspondence with group numbers.

・The internal radio has a control channel (hereinafter referred to as the C channel. The frequency is 903.0125 MHz) and a communication channel (hereinafter referred to as the S channel. Frequencies are allocated every 25 kHz from the C channel.
9 channels).・Gunnal wireless device is the first
CPU 1, RAM 2 and PL as shown in the figure
It has an L circuit 16, and the setting of the C channel and S channel is carried out by the calculation of the CPU 1 and by changing the division ratio of the programmable counter 17 provided in the PLL circuit 16. In order to communicate with each other between the calling side and the called side/local radio equipment, a calling group code is created on the calling side/local radio equipment and the calling button Ks is pressed. The calling group code corresponds to the calling dial number on a telephone, and is organized by pressing the numeric button KOτ with the number 9. The group number has 2 to 5 digits. Two sets of standby group numbers may be prepared. In addition, the group number ooooo is used when communicating with an unspecified party. Group numbers for calling and standby can be organized arbitrarily, but group numbers for standby must be prepared at all times.

For this purpose, a group number storage means for storing the group number is provided.

If you also memorize the group number for calling, press the number button Ko~
By using 9 as address data indicating the storage location, a function similar to that of the abbreviated gouillage in a stain filling machine can be obtained. RAM 2 is used for storage. For example, as shown in FIG. 2, the RAM 2 has group code memories Mo to M, and M' each consisting of one word of 0 to 31 bits. 1
Bits 0 to 7 of the word are the channel code Qmo-e
m* * em' + 8 bits to 27 bits are group code mo''-mg, m' + 28 bits are A storage bits, 29 bits are B storage bits, and 30.31 bits are empty. Group code memory MO % In order to manage M9, a flag table Fi is prepared, and 0 to 9 bits are used to manage the receiving side, and 16 to 25 bits are used to manage the calling side.
9 bits and 16 to 25 bits correspond to group code memories MO to M9, respectively, and the position of the act bit indicates the group code to be referenced. Group code) Memory M' stores the received group code m' and channel code am' for work. For example, flag table Fi
The 1st, 2nd and 19th bits are active bits.

If so, first and second standby group codes mp 1ms
is the group code town and m2, and the calling group code mt is the group code m
It becomes 3. The GLODARAMs used by the CPU 1 include the standby operation program shown in FIG. 3, the acquisition operation GLODARAM, a calling operation program executed through the B connector, and a telephone conversation operation program executed through the D and E connectors. The standby operation GLODARAM detects the presence or absence of a call request by the call button Ks, the presence or absence of a monitor request by the monitor button 13, and the presence or absence of an incoming call by the standby group code-reception group code subroutine. These operations are performed while setting the C channel. When an incoming call is detected, the program transitions from the A connector to the capture operation program, sets the preferred call channel for the received channel code, and if the transmission from the calling party is interrupted for more than 30 seconds, the program transfers to the capture operation program via the 2 connector. Return to the start address of the standby program. The audio signal on the calling side is transmitted through the antenna 23, the mixer 25, the intermediate frequency circuit 26 (set to the communication channel), the detector 827, and the audio circuit 28.
and can be monitored via the speaker 29.

The above-mentioned 4-channel wireless device has a drawback that it cannot store the time of call arrival corresponding to the group code when the power is turned on and the user is away in standby mode.

The present invention has been made in view of the above points, and an object of the present invention is to provide a personal radio device that stores the time at which the group number stored in the group number storage means is referred to for communication together with the group number. .

Hereinafter, one embodiment of a personal wireless device according to the present invention will be described in detail with reference to the drawings.

Figure 4 shows the group code matching routine. The group code matching subroutine is provided as a replacement for the standby group code-receive group code subroutine of the standby operation zologram shown in FIG. Any two of the flag table Fi shown in FIG. 2 are set as act bits. Among these act bits, the group code cho~m stored in the group code memory M1%M9 corresponding to the lower act bit is the standby group code mp, and the group code cho~m9 corresponding to the upper act bit is the standby group code. Let it be ms. When the group code m' is received, the program indicator PI is set to 1 if the time button 39 shown by the dotted line connection in FIG. 1 is operated.

When the time button 39 is not operated, the program indicator PI remains at 0. Received group code m′
It is determined whether the first standby group code mp matches or does not match, and if they match, the program tag PT is set to 1. When a match with the second standby group code m8 is determined, the program tag PT becomes 2. standby group code mp
When it is determined that □ does not match m8, the zologram tag is set to 3. It is determined whether or not the program tag PT is not equal to 3. If it is determined that the program tag PT is not equal to 3, the branch destination is determined based on the numerical value of the program indicator PI. When the program indicator PI is 1, the time memo shown in Figure 5! The memory address of JABj (j is assumed to be 0 to 31 for the sake of explanation) is determined. The time memory ABj consists of 1 word and 32 bits, 0 bits to 15 bits are time data TM, 16 bits to 19 bits are group code memory Mo % Memory address ME of M9, 20 bits to 23 bits are the human shock level. Memorize LV. 24 bits to 31 bits are reserved. Once the memory address of time memory ABj is determined, time data TM
Furthermore, when the program tag PT is 1, the memory address ME of the group code memory M1% M corresponding to the lower act bit of the two act bits of the flag table Fi is stored. Also, at the same time, the sensitivity level L
Remember V. When the program tag PT is 2, the memory address ME of the group code memories M1 to M9 corresponding to the upper act bit is stored. In addition, the table E being executed
X has a configuration of 0 to 31 bits and is a time memory ABo-AB31
It corresponds to

Here, the group code town, m2, m3, and m4 are group numbers 12345, 22222, and 30000, respectively.
, 45678. The standby group number is 12345, 22
222, the flag table Fi is 1 bit and 2 bits.
The bit is now an act bit. When a call arrives at 12345, the standby group code mp and the reception group code m' are 12345 and match, so the time memory ABo is
For example, 1 indicating 13:24 to the O pittle 15 bit of
Since the program tag PT is 1, the address data rlJ of the group code memory M1 shown in FIG. 2, which corresponds to 1 bit serving as the lower focus of the flag table Fi, is stored in m'==mp where 324 is stored. At the same time, the level of sensation is memorized. The standby group numbers are 22222 and 456
When changed to 78, the flag table Fi has 2 bits and 4 bits.
If the bit is not the act bit and a call arrives at 45678, take note of the time! For example, address data "4" is stored in J ABI at 13:32. Time memory AB3. Once you have memorized it, take a note of the time at the first address! Top coated from J ABo. When the series of storage operations is completed, the active position of the table EX being executed is changed. Running table E
The act bit of X indicates the starting point of the cycle of usage. When a time display button (not shown) is operated, the time and the group number of the incoming call are displayed on the display gray 7. The personal wireless device according to the present invention displays the time when the group number stored in the group number storage means was referenced. Since the structure is equipped with a time storage means for storing the time in correspondence with the group number, it is possible to make a call,
It has the feature of being able to store the time of incoming call in correspondence with the group number. Therefore, there is an effect that the personal wireless device can be operated in accordance with the stored time data and group number.
