方形や長方形等の任意の形に設定することができる。The radio control station 1a receives the position information of the mobile station 3a,
Set the calling area of 3a and store it in its own home memory. As a method of setting the calling area, as shown in FIG. 2, there is a method of setting the calling area in a substantially circular shape by configuring the wireless area within a certain distance from the wireless zone in which the mobile station is located. In addition, the calling area can be set to any shape such as a square or a rectangle.

According to 2a to 2f, the incoming call information is transmitted on the downlink control channel in each wireless zone. The transmission timing in each wireless zone is usually the same, but since the calling area is different for each mobile station, when there are incoming calls to multiple mobile stations at the same time, the timing for sending the incoming call will be different for each wireless zone. There is also.

That is, when the power of the mobile station 3a is turned off, the position information of the mobile station 3a in the home memory of the radio control station 1a and the call information in the mobile station memory are maintained without being erased, and the mobile station powers on. Sometimes the wireless zone in which it is located is determined, and if it is included in the calling area in the memory, the location is not registered again,
If it is outside the calling area, the location of the mobile station 3a is registered by the same method as in the above embodiment.

ともできる。Furthermore, the base station, as the base station information in the downlink control channel, always transmits the identification codes of all the wireless zones that make up the calling area in the surroundings as described above, and the mobile station 3a uses the same at the time of location registration. By referring to the base station information, the calling area of the own station can be recognized and stored in the mobile station memory.
次に第二の実施例として、上記の在圏無線ゾーンの識別

動する場合に位置登録を行う。In this case, the calling area of the mobile station 3a is configured by a wireless zone existing within a certain distance from the wireless zone in which the mobile station 3a has registered the location, and the calling area is set to be substantially circular.
Use two-dimensional coordinates etc. to indicate the position of the wireless zone,
The coordinates are used as the identification code of the wireless zone to notify the mobile station 3a through the downlink control channel. For example, the mobile station 3a stores the identification code of the wireless zone at the time of location registration, and when performing the wireless zone transition, receives the destination wireless zone identification code and calculates the identification codes of the two wireless zones. , Calculate the distance between the wireless zones. From the calculated inter-radio zone distance, it is determined whether or not the transfer destination radio zone is within the calling area, and position registration is performed when moving beyond the calling area.

らの距離が「２」を越えるため位置登録を行う。FIG. 5 is an example showing the position of each wireless zone in the two-dimensional coordinates of the base station. When the radius of the calling area is set to "2" in terms of the distance between the base stations, the calling area of the mobile station 3a whose location is registered by the base station 2a (4, 4) is "2" with the base station 2a as the center. This is the wireless zone of the base stations 2a to 2e within the circle 6 (inside the solid line in the figure). When the mobile station 3a moves to the wireless zone of the base station 2b (3,3), the location registration is not performed again, and when it moves to the wireless zone of the base station 2f (5,6), the distance from the base station 2a Since "2" exceeds "2", position registration is performed.
また以上説明した方法の他に、移動局が無線ゾーンの位
置関係をメモリ内に記憶し、これに基づいて位置登録の
必要性を判定する方法も可能である。In addition to the method described above, a method in which the mobile station stores the positional relationship of the wireless zones in the memory and determines the necessity of the position registration based on this is also possible.

減少することがわかる。FIG. 7 shows the results of comparing the effect of the present invention with the conventional example.
In the method of the present invention compared with this conventional example, assuming that the calling area is a square, the horizontal axis represents the length of one side, and the vertical axis represents the average number of times one subscriber registers the location in 5 hours. In this figure
6a and 6b are the conventional method, and it is assumed that the starting points are uniformly distributed in the area. In the method of the present invention, 7a and 7b start from the center, and when the boundary is crossed, the paging area is reset with the point as the center. It is assumed that each a has an average traveling speed of 20 km / hour and b has an average traveling speed of 10 km / hour, and the direction is randomly changed every 500 m. It can be seen from FIG. 7 that the present invention significantly reduces the number of position registrations as compared with the conventional method.

動局による位置登録の頻度を減少させることができる。As described above, according to the present invention, when the mobile station transmits the radio zone in which the mobile station is located as position information to the radio control station and the radio control station sets the calling area of the mobile station, By individually setting the paging area centered on the wireless zone in which the mobile station is located, the frequency of transition to the paging area of randomly moving mobile stations is reduced, and the frequency of location registration by mobile stations is reduced. You can

がもたらす効果は大きい。Particularly, in mobile radio communication, as the number of mobile stations increases, a radio zone and a small zone of a calling area are indispensable in order to improve frequency utilization efficiency by repeatedly using the same frequency. At this time, if the number of mobile stations increases and the number of zones becomes smaller, the frequency of mobile station call area shifts sharply, and the traffic for location registration in the uplink control channel increases significantly. Therefore, the present invention that reduces the frequency of location registration by the mobile station without widening the calling area has a great effect.
