Abstract

PURPOSE:To transmit entry/leave data independently of the order of generation of data by activating an entry data transmission means and a leaving data transmission means only at the independent time element to allow them not to follow immediately the designation and change of a group code transmission means. CONSTITUTION:The titled equipment is provided with the group code designation means for designating a group code for composite command communication and the operation of the group code command means designates a group code prepared in an identifying ROM8. The entry data transmission means to a concerned group and a leave data transmission means consist of a program started at an independent period respectively. The execution control for programs is executed by an act bit control. That is, the program start is executed independently of the entry and leaving and independently of a time of operation of a group code designation button 12 and of incoming/outgoing. Whether or not the data is transmitted is decided by a flag relating to the program. There is an opportunity that no data is transmitted for 84sec maximum after leaving or entry takes place, it gives no trouble because the most frequent traffic is 0.5.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an MCA wireless communication device, and particularly to an MCA wireless communication device for a mobile station that can perform complex command system communication.

[Technical background of the invention and its problems]

The MCA system consists of an MCA control station and a group of participating stations equipped with MCA radio communication equipment. Furthermore, a unit subscriber station group is composed of a command station and a mobile station. One MCA system is above)
, lower 9 control channel 1 line and upper blade, lower] speech channel 1
It consists of 5 lines. A subscriber station group has a group code consisting of a telephone number's area code, city code, telephone type code corresponding to the representative subscriber number, system number, and knee decode. The telephone type code is a 4-pit code number that corresponds to radio wave management stations nationwide and the Okinawa Post Office. The subscriber stations belonging to the subscriber station group perform call origination and call reception processing using this group code written in the identification ROM. The MCA control station always transmits the control signal Fd shown in FIG. 1 from the lower 9 control channel as a time slot. The lower control signal Fd is bit synchronization d1#7 frame synchronization d
! , first block data d3m, and second block data d4, and the first block data d includes an electric model code 11 and a system number al as shown in FIG.

This electric model code Ill and system number a! is called a system code and is a unique number assigned to a wireless zone. In the identification ROM, a system code and frequency information of a downlink control channel through which the system code is transmitted from the MCA control station to the subscriber station and an uplink control channel used for calling the subscriber station are written. The subscriber station sets the downlink control channel using the frequency information of the downlink control channel, and sends the downlink control signal F'
Receive d.

If the system code written in the identification ROM matches the electronic type code a1 and the system number a2 of the first clock data d3 shown in FIG. 2, the standby condition is established and it becomes possible to make and receive calls. When there is no incoming call, the second group and data d4 shown in FIG. 3 are "all O". When there is an incoming call, the second group shown in Fig.
bit) and knee decode alo (40-49 pits) are organized.

The subscriber station on the called side verifies the second block r-data d4 based on the group code written in the identification ROM and identifies that there is an incoming call. After identifying the incoming call to our own group, the channel number a (50 to 50) organized in the second block f-ta d4
59 bits) matches one of the plurality of channel numbers written in the identification ROM. When the communication channel verification is OK, the upper and lower communication channels are set using the specified communication channel numbers. When making a call, the uplink control signal F0 shown in FIG. 4 is transmitted to the MCA control station via the upper control channel. Upstream control signal F. consists of bit synchronization Ul, 7-frame synchronization U8, and calling data U3.

The call data U3 has a 36-bit configuration as shown in FIG.
bs (16 to 19 pits), system number b@ (20 to
25 bits, g) and knee decode by (26 to 35 bits). The group code of the calling data U3 is transmitted from the MCA control station as the second block data d4 of the downlink control signal Fd.

The calling subscriber station and the called subscriber station execute the same call processing program. By executing the call processing program, calls can be made in a simplex manner. Since the subscriber station that becomes the command station is fixed in its home zone, it does not need to have multiple group codes, but since a mobile station moves within the range of multiple wireless zones, multiple group codes must be pre-programmed in the identification ROM. It is now possible to set If the electric type code, system number, and user code of the group codes are GA, QB, and GC, respectively, there is a first case where GA is different between multiple group codes (QB and GC have no conditions), GA There is a second case where GA and GB are the same but different GB, and a third case where GA and GB are the same but GC is different. The first case is called nationwide wide area communication, the second case is called local wide area communication, and the third case is called multiple command system communication. In complex command system communication, it is possible to join or leave a different command station by manually specifying one group code from a plurality of group codes stored in the identification ROM K. This incorporation and withdrawal can be done freely. In addition, information on transfers and withdrawals will be reported orally to the command station each time. Incorporation,
Although there is a considerable degree of uncertainty between the time when withdrawal information is generated and the time when information is required, the design traffic is set to 14 erlangs (per channel) with a call rate of 0.5 and an average holding time of 20 seconds and 15 channels. Judging from this, it is not reasonable to immediately send information to the command station at the time it is generated. Code a s Id in Figure 2, system information, a4 is command, 1

Up to 15 commands can be generated. rooolJ is used for general connections and rooloJ is used for wide area connections. Hex 4 and 5't-compound commands, 4 is defined as an incorporation data transmission command, and 5t-separation data transmission command. Others are used for adjacent communication, nationwide wide area communication, etc. commands as necessary. When the transfer data transmission command 42'6i time is activated, the judgment box 43 judges whether the line memory LM has 7 data. Depending on the judgment, if the mate side group code GNM is currently in use, the flow goes to judgment box 51. In the judgment box 51, it is judged whether or not the positive mate PM of the 7 lug area FLG is activated. If Positive Mate PM has been activated, the transfer data has already been sent, so process 54.
The negative mate is set to 8M line act and control is passed to the execution management program. If the positive mate PM has not been activated, it is activated in process 52, and in process 53, the individual subscriber station number GD (20 to 25 pi, g) of the mate side group code GNM shown in FIG. 13, which is the active side, is activated. The call data U3 shown in FIG. 5 is organized into a spare b4. In process 47, "4" indicating the transfer data transmission command is organized into calling data U3, and b2.The organized calling data U3 is transmitted in process 48, and after the transmission is completed, the command is returned to the general connection. , and b4ff of call data U3

In process 68, withdrawal data is transmitted. In process 69, the command code is returned to general connection, and in process 70, the organized individual subscriber station number is deleted. The knee decode organized in b7 of the calling data U3 is rewritten to the current one by the calling program 35 in FIG. 9 every time a call is made, so there is no need to change it. When the mate side hood GNM is currently in use, judgment ZEX 631 processing 64, 55, 60 and 71 are executed.

Here, when the power is turned on, a power-on program 19 shown in FIG. 8 is executed. When the power-on program 19 is executed, a downlink control signal is received on the downlink control channel written in the identification ROM.

When frame synchronization is established and the received system code matches the system code written in bits O to 9 in FIG. 12 or 13, the standby program 2 shown in FIG.
Transition to 3. Until the transition to the standby program 23 occurs, the operation of the group code designation button 12 shown in FIG. 6 is a don't care. Assume that the group code designation button 12 is pressed to designate the mate side.

If there is no incoming call or outgoing call at this point, the standby program 2
Return to the first address of 3. When 42 seconds have elapsed, the 42 second marker 6a shown in FIG. 6 activates the transfer data transmission program 42 shown in FIG. 10 or the withdrawal data transmission program 56 shown in FIG. are executed alternately. In other words, the program is started at a time that is independent of the order of leaving and joining, and is independent of the time when the group call designation button 12 is operated and the time when a call is received or made. Whether data is transmitted or not depends on the seven lags involved in the program. Although data may not be transmitted for up to 84 seconds from the time of departure or joining, this is a delay that does not cause any practical problems since the call rate during the busy hour is 0.5.

〔Effect of the invention〕

The MCA radio communication device according to the present invention includes group code designation means;
A transfer data transmitting means for transmitting transfer to the group specified by the group code specifying means via a control channel, and a transfer data transmitting means for transmitting transfer from the group to which the designation has been canceled by the group code specifying means via the control channel. withdrawal data transmission means to transmit;
Because of this configuration, the transfer data transmitting means and the withdrawal data transmitting means operate only in independent time elements, and are characterized in that they do not immediately follow changes in the designation of the group code transmitting means. Therefore, there is an effect that transfer/withdrawal data can be transmitted regardless of the order in which the data is generated.
