関係に各々独自に設定していた。[0004] In the conventional research for practical use, in order to make a mobile station compatible with both public communication and private communication, a transmission / reception slot for a control channel of a superframe transmitted from a public base station is used for both public communication and private communication. , The interval value of superframe transmission is set independently for the public communication transmission / reception slot and the private communication transmission / reception slot independently of each other.

る。In the radio telephone system, one time slot is usually set to 5 msec for the control channel, and the time slot assigned to the mobile station is 5 msec.
The number of sec is n times (n is an integer), and the transmission / reception slot for public communication has the value of n defined as 20 and the transmission / reception slot for private communication is n.
Is allowed to be set to any value greater than or equal to 25. The value of n is defined as an interval value.

As an example of the superframe (1), one frame is composed of a bit group BC transmitting radio channel notification information, bit groups P1 to P6 transmitting incoming call information, and a bit group SC transmitting various control information. Each bit group is configured to be transmitted from the base station in the transmission / reception slot, one bit group at each arrival of each transmission / reception slot.

に無関係に送出されていく。The transmission of the superframe by each transmission / reception slot described above is different in time between the transmission / reception slot for public communication S1 and the transmission / reception slot for private communication S2 because transmission frequencies for public communication and for private communication are different from each other. Are sent to each other independently of each other.

Since 1 is set to 20, the period T1 of the public communication transmitting / receiving slot S1 is 100 msec, and the interval value n of the private communication transmitting / receiving slot S2 is n.
When 2 is set to 25, the cycle T2 of the transmission / reception slot for private communication S2 is 125 msec.

ずる。According to the conventional example described above, the cycle T2 of the private communication slot S2 is set independently of the public communication transmission / reception time slot S1 and set to a different cycle. In FIG. 2, both transmission / reception slots S1 and S2 approach each other in time as shown by (a) and (b), or both transmission / reception slots S1 and S2 as shown in (c) and (d). The phenomenon that they overlap in time occurs.

必要とし、基地局の構成が複雑かつ高価となる。In order to successfully transmit the superframes for both public communication and private communication even when there are transmission / reception slots that are close to each other or overlap with each other, the public communication to the base station is required. This requires separate wireless devices and modems for wireless communication and wireless devices and modems for private communication, which makes the configuration of the base station complicated and expensive.

う問題がある。In addition, in order to reduce the size and weight of the mobile station, usually, the equipment of the wireless device and the modem is set as one set, and the superframe for both public communication and private communication is received by switching the frequency in the wireless device. However, when both transmission / reception slots S1 and S2 approach each other at a frequency switching speed or more and overlap, either or both superframes cannot be received (that is, from the base station). Parallel monitoring of public superframes and self-employed superframes is temporarily disabled.)

It is sufficient to equip the mobile station with a set, and it is an object of the mobile station to obtain a transmission / reception slot setting system in which parallel monitoring of the public communication transmission / reception slot S1 and the private communication transmission / reception slot S2 is always possible in the control channel.

In addition, the time intervals at which the transmitting and receiving slots are closest to each other are set to be equal to or longer than the frequency switching time of the wireless devices of the base station and the mobile station.

る。The interval value ratio of the transmission / reception slots for public communication and private communication is set to an integer ratio, and the time difference in the closest state of both transmission / reception slots is set to the time difference that can be followed by the frequency switching of the wireless device. Since the transmission and reception slots of both sides are not extremely close to each other or overlap with each other, it is sufficient to provide one set of frequency switching type wireless devices at the base station. In a mobile station provided with only one set of wireless devices, parallel monitoring of public communication superframes and private communication superframes is always possible.

とはない。Further, the time interval T when the public communication transmission / reception slot S1 and the private communication slot S2 are closest to each other is the frequency switching between the radio devices of the base station and the mobile station (transmission frequency of the super frame for public communication and (Mutual switching with the transmission frequency of the super frame for private communication) is set sufficiently long to follow, and as described above, the interval value n2 of the private communication transmission / reception slot S2 is the interval of the public communication transmission / reception slot S1. Since it is set to an integer multiple of the value n1, both transmission / reception slots S1,
S2 does not approach at a time interval shorter than the time interval T described above.

双方のスーパーフレームの並行監視が可能となる。As described above, according to the present invention, the ratio of interval values of superframe transmission / reception slots for public communication and private communication is an integer ratio, and the closest approach time of both transmission / reception slots. The interval is set to be equal to or longer than the frequency switching time of the radio equipment of the base station and the mobile station, and both transmission / reception slots approach each other abnormally,
Or, since they do not overlap each other, it is not necessary to equip the base station with a plurality of control channel radios and modems. One set of frequency switching radios can be used to provide both superframes for public communication and private communication. It is possible to transmit in parallel, and since the mobile station does not cause time competition in both transmission / reception slots, even in a wireless device with a frequency switching speed that is normally used, both superframes are always transmitted. It is possible to monitor in parallel.
