のである。[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a wireless service area that consists of a plurality of paging areas, and when a mobile station turns on the power or detects that the paging area has changed. In a mobile radio communication system that transmits the calling area of a mobile station by registering its location in a home memory provided in a control station, each mobile station transmits information about its surrounding area around the registered radio zone. The present invention relates to a location registration control method that reduces the frequency of location registration by mobile stations and efficiently performs incoming calls by setting a wireless zone as a calling area.
移動無線通信では、移動する移動局に対する着信情報を
効率的に送信するため、無線制御局が配下の移動局の位
置を把握し、その位置情報に基づいて、移動局の呼出し
エリアを選択する方法がとられる。In mobile radio communications, in order to efficiently transmit incoming call information to moving mobile stations, a method is used in which a radio control station grasps the location of the mobile station under its control and selects a paging area for the mobile station based on that location information. is taken.
このため、移動局は電源投入後、無線制御局に対して位
置登録を行い、以降は、移動局が移動して呼出しエリア
の境界を横断した場合、再度位置登録を行うのが普通で
ある。For this reason, after the mobile station is powered on, it typically registers its location with the radio control station, and thereafter, when the mobile station moves and crosses the boundary of the calling area, it registers its location again.
この場合、位置登録の頻度を減少させるため、通常、呼

度が増大する。In this case, in order to reduce the frequency of location registration, the paging area is usually made up of a plurality of wireless zones, and the incoming call information is paging using a wide area/simultaneous paging method. If the paging area is expanded to further reduce the frequency of location registration, the number of mobile stations within the paging area will increase, and the frequency of paging will increase.

抑止する方法も存在する。In addition, in the conventional method, there are cases in which location registration is performed even when the frequency of the control channel that broadcasts location information to the mobile stations 3a to 3C changes, and furthermore, simply turning off the mobile station power does not allow past location information to be registered. As a configuration in which the location information is not lost, there is also a method of inhibiting location registration again if there is no change in location information when the power is turned on.

使用できない問題が生ずる。Therefore, as shown in FIG. 6, when the mobile station 3a exists near the boundary line of the paging area and repeatedly changes the paging area, the conventional method has the drawback of repeatedly registering its location with the radio control station. was there. Particularly when the number of mobile stations increases, the increase in location registration frequency occupies the uplink control channel on the radio link, causing the problem that the control channel cannot be used.

方法により、移動局３ａの位置登録を行う。Further, in the above embodiment, a method is shown in which the location is always registered when the power of the mobile station 3a is turned on, but this can be omitted. That is, when the mobile station 3a is powered off,
Maintaining the location information of the mobile station 3a in the home memory of the radio control station 1a and the calling information in the mobile station memory without erasing it,
When the mobile station is powered on, it determines the wireless zone in which it is located, and if it is included in the paging area in the memory, it does not register the location again, but if it is outside the paging area, it uses the same method as in the above embodiment. The location of the mobile station 3a is registered.

こともできる。Furthermore, the base station constantly transmits the identification codes of all wireless zones constituting the calling area in the vicinity as described above as base station information in the downlink control channel.
By referring to the base station information during location registration, the mobile station can recognize its own calling area and store it 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

越えて移動する場合に位置登録を行う。In this case, the paging area of the mobile station 3a is constituted by a radio zone existing within a certain distance from the radio zone in which the mobile station 3a has registered its location, and the paging area is set in a substantially circular shape. Two-dimensional coordinates or the like are used to indicate the position of the wireless zone, and the coordinates are reported to the mobile station 3a via a downlink control channel as an identification code of the wireless zone. For example, the mobile station 3a stores the identification code of the wireless zone at the time of location registration, and when performing a wireless zone transition, receives the wireless zone identification code of the transition destination, calculates the identification code of the two wireless zones, and , calculate the distance between the wireless zones. Based on the calculated inter-wireless zone distance, it is determined whether the destination wireless zone is within the paging area, and location registration is performed when moving beyond the paging area.

め位置登録を行う。FIG. 5 is an example showing the position of each wireless zone using two-dimensional coordinates of the base station. If the radius of the paging area is set to "2" in terms of the distance between base stations, the paging area of the mobile station 3a that has registered its location with the base station 2a (4, 4) will be a radius of "2" centered on the base station 2a. This is the wireless zone of the base stations 2a to 2e within the circle 6 (within the solid line in the figure). Mobile station 3a is base station 2
When moving to the wireless zone of b (3, 3), the location is not registered again, and when moving to the wireless zone of base station 2f (5, 6), the distance from base station 2a exceeds "2" Register your location.
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 is also possible in which the mobile station stores the positional relationship of wireless zones in its memory and determines the necessity of location registration based on this.
第７図に本発明の効果を従来例と比較した結果を示す。FIG. 7 shows the results of comparing the effects of the present invention with the conventional example.

べても位置登録回数は大幅に減少することがわかる。The method of the present invention compared with the conventional example assumes that the calling area is a square, the horizontal axis represents the length of a side, and the vertical axis represents the average number of times one subscriber registers their location in 5 hours. In this figure, 6a and 6b are the conventional methods, and it is assumed that the starting points are uniformly distributed within the area. 7B and 7b use the method of the present invention to start from the center, and when the border is crossed, the calling area is reset to center around that point. It was assumed that a had an average moving speed of 20 km/h, b had an average moving speed of 10 km/h, and the direction changed randomly every 500 m. From FIG. 7, it can be seen that the number of location registrations is significantly reduced in the present invention compared to the conventional method.
以上説明したように、本発明によれば、移動局が位置情

移動する移動局の呼出しエリア移行の頻度は減少し、移
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 explained above, according to the present invention, when a mobile station transmits the radio zone in which it is located as location information to a radio control station, and when the radio control station sets a calling area for the mobile station, By individually setting a paging area centered on the wireless zone in which the mobile station is located, the frequency of paging area shifts of randomly moving mobile stations is reduced, and the frequency of location registration by the mobile station is reduced. Can be done.
特に、移動無線通信では、移動局数の増大に伴い、同一
周波数の繰り返し利用により周波数の利用効率を高める

もたらす効果は大きい。In particular, in mobile radio communications, as the number of mobile stations increases, radio zones and small calling areas are becoming essential in order to increase frequency usage 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 stations changing to a paging area will increase rapidly, and the traffic for location registration in the uplink control channel will increase significantly. Therefore, the present invention, which reduces the frequency of location registration by mobile stations without widening the calling area, has a great effect.
