毎の伝達情報信号とで構成されている。As shown in FIG. 2 (a), the paging signal transmitted from the base station connects n paging signals for each group having a signal length t 0 ,
It is composed of a signal with a period of length T 0 . The signal structure for each group is, as shown in FIG. 2B, a synchronization signal, m address signals which are identification signals of called subscribers belonging to the group, and each receiver corresponding to each address signal.

And a group synchronization signal indicating that. Each subscriber receiver operates so as to receive the group synchronization signal and receive only the time slot in which the signal of the group to which the own receiver belongs is sent, and does not receive other time slots.

内容を表示する。The call signal for each group is composed of a synchronization signal, a plurality of address signals (address 1 to address m) for identifying the called subscriber in the group, and a portion of a transmission information signal corresponding to this address. , If the address signal and the address of the self-receiver match, each receiver judges that there is a call to the receiver, decodes the subsequent transmission information signal, and transmits the transmission information to the display unit together with the sound. Display the contents.

かった。That is, when a person calls the wireless paging receiver with a display, according to statistical data, it is used as a tone only that does not send out transmission information with a probability of about 50%. In this case, the bit effective utilization rate η of the information transmission section following the synchronization signal is Therefore, for example, if h 3 = 3h 2 , the effective utilization rate is about 62.5%. As described above, in the conventional method, the number of subscribers that can be accommodated is limited, and it is not possible to effectively use radio waves.

伝達情報信号を伴わない呼出のアドレス信号を連続して
伝送することを特徴とする。According to the present invention, a ringing signal for calling a called receiver is divided into a plurality of groups, and a ringing signal for each group includes a synchronization signal common to each group and a plurality of address signals for identifying individual receivers and this address. In the radio selective calling system, which is composed of a transmission information signal corresponding to the signal, transmits this calling signal from the base station, and each receiver intermittently receives the calling signal belonging to its own group, the above synchronization signal for each group. In a specific section following the section, a calling address signal without a transmission information signal is continuously transmitted.
基地局は、各グループ別呼出信号ごとに同期信号とアド
レス信号あるいは同期信号とアドレス信号に伝達情報を
付加した呼出信号を構成して送出する。The base station constructs and sends a calling signal in which transmission information is added to the synchronizing signal and the address signal or the synchronizing signal and the address signal for each calling signal for each group.
この場合、伝達情報信号を伴わないトーンオンリの呼出

と伝達情報信号の組合せの信号を送出する。In this case, regarding the tone-only calling without the transmission information signal, only the address signal is sent to a specific section of the information transmission section following the synchronization signal, for example, a section of a specific number of bits following the synchronization signal, and to the other sections. Sends out a signal which is a combination of the address signal and the transmission information signal.
アドレス信号のみの区間で呼び出された受信機は自己が
トーンオンリで呼び出されたことを認識して鳴音のみの
呼び出しを行う。The receiver called in the section of only the address signal recognizes that it is called in tone only, and calls only the sound.

FIG. 1 is a diagram showing a signal configuration according to an embodiment of the present invention. FIG. 1 (a) shows the entire signal configuration, and FIG. 1 (b) shows a group 1 signal configuration. FIG. 7C shows the structure of the synchronization signal.

号の先頭位置の同期信号も従来と同様であり、その同期
信号の信号速度も同様である。The ringing signal transmitted from the base station is similar to the conventional one in that the ringing signal for each group is composed of signals of a period T 0 , which is obtained by connecting n ringing signals for each group of time t 0. The synchronizing signal at the head position of is also the same as the conventional one, and the signal speed of the synchronizing signal is also the same.
本発明の特徴とするところは、被呼出加入者受信機に対

者に対する伝達情報がない場合の呼び出しは、同期信号
に続く特定の情報伝送区間にそのアドレス信号を連続的
に配置して、伝達情報信号が付加されるアドレス信号の
部分と分離して配置するところにある。A feature of the present invention is the configuration of the selective call signal corresponding to the called subscriber receiver. That is, when there is no transmission information for the called subscriber, the address signal is continuously arranged in a specific information transmission section following the synchronization signal to separate it from the portion of the address signal to which the transmission information signal is added. It is in the place to place.
以下具体的にその信号構成を示す。ここでは、同期信号
の終りからh5のビット数の区間は、アドレス信号のみを
配置する。その後に続くh6のビット数の区間について
は、従来どおりアドレス信号および伝達情報信号を配置
する。すなわち、h5のビット数の間に伝達情報を付加す
る必要のない呼出のアドレス信号のみを配置し、そして
その後に続くh6のビット数の区間は従来どおりアドレス
信号＋伝達情報信号の形で基地局から伝送される。The signal configuration will be specifically shown below. Here, only the address signal is arranged in the section of the bit number of h 5 from the end of the synchronization signal. In the subsequent section of the number of bits of h 6, the address signal and the transmission information signal are arranged as in the conventional case. That is, only the address signal of the call that does not need to be added with the transfer information is arranged between the number of bits of h 5 , and the subsequent section of the number of bits of h 6 is in the form of address signal + transfer information signal as before. It is transmitted from the base station.
なお、ここで、 h5＝ｐ×（h2＋h3） （ｐは整数）の関係が成立すればよい。成立させられな
い時には、h5−ｐ×（h2＋h3）ビットを余りのビットと
し、h5の最後に配置してもよい。Here, the relationship of h 5 = p × (h 2 + h 3 ) (p is an integer) may be satisfied. When it cannot be established, the remaining bits may be h 5 −p × (h 2 + h 3 ) bits and may be placed at the end of h 5 .
この本実施例の伝送効率について検討してみる。The transmission efficiency of this embodiment will be examined.
従来方式の伝送容量をＣ、本方式の伝送容量をＣ′と
し、h3＝3h2の関係があり、h5＝（h2＋h3）すなわち、
ｐ＝１の時には、従来の伝送方式の情報伝達容量値Ｃ、
本方式による情報伝送容量Ｃ′とすると、 となる。ここで、第１図において、h3＝3h2、h5＝h2＋h
3であるから、ｋ＝４である。また、h5＝h2＋h3である
からｌ＋１＝ｍであり、 となる。Letting C be the transmission capacity of the conventional system and C ′ be the transmission capacity of this system, there is a relationship of h 3 = 3h 2 , and h 5 = (h 2 + h 3 )
When p = 1, the information transmission capacity value C of the conventional transmission method,
If the information transmission capacity C'by this method is Becomes Here, in FIG. 1, h 3 = 3h 2 , h 5 = h 2 + h
Since it is 3 , k = 4. Also, since h 5 = h 2 + h 3 , l + 1 = m, Becomes
ｌ＝３とすれば、Ｃ′/C＝1.75となり、75％増となる。
この場合、トーンオンリと表示付きの収容比は、4:3と
なり、ほぼ統計トラヒックに近似できることとなる。If l = 3, C '/ C = 1.75, which is an increase of 75%.
In this case, the accommodation ratio with tone-only and display is 4: 3, which is close to statistical traffic.
受信機は、同期信号に続くh5のビット数はトーンオンリ
のみが受信され、それ以後のh6のビット数はアドレス信
号＋伝達情報信号が受信されるものとして受信動作を行
えばよい。The receiver may perform the receiving operation assuming that only the tone only is received for the number of bits of h 5 following the synchronization signal and the number of bits of h 6 after that is the address signal + the transmission information signal.
以上説明したように、本発明は、表示付き無線呼出方式

信号伝送容量を増大でき、加入者収容数を増加して電波
の有効利用を図ることができる効果がある。As described above, even if the present invention is the wireless paging system with display, when the message content to the called receiver is the tone paging only the address, the address sent to the signal from the base station is addressed. Since only the signal is transmitted,
The signal transmission capacity can be increased, the number of subscribers can be increased, and effective use of radio waves can be achieved.
