し、移動局の位置情報を更新している。2. Description of the Related Art In a car telephone system and a portable telephone system, a service area is divided into an appropriate size, and this is used as a location registration area of a mobile station to make a call based on a location area. For this purpose, the mobile station sends a signal for notification to the fixed network (switching station) side every time the power is turned on or the transmission and the movement between the location registration areas are performed, and the location information of the mobile station is updated. .

大することになり、このことによる呼の接続遅延や高ビ
ジー率の発生などサービスの低下が懸念されている。By the way, an increase in the number of location registration areas due to an increase in the number of mobile stations and accompanying narrowing of a wireless zone causes an increase in communication traffic for location registration, and causes an increase in the fixed network and mobile stations. As a result, the load of the control signal during the call increases, and there is a concern that the service may be degraded due to a call connection delay or a high busy rate.

である。According to the present invention, in order to solve the above-mentioned problems, it is necessary to make the radio channel disconnection signal carry location information for location registration in a call disconnection sequence at the end of a call. Features. That is, at the end of a call, a radio link from the exchange to the mobile station having means for recognizing a change in the location registration area of the mobile station during the call.
Notify by placing location information on the channel disconnect signal and after the call ends
In this case, location registration is not executed from the mobile station .

3, R21 to R23 are wireless zones, MS is a mobile station,
L1 and L2 indicate location registration areas, and NW indicates a fixed network (switching station). Each wireless zone has a wireless base station.
Now, when the mobile station MS starts a call in the radio zone R11, the fixed network NW is already in the position registration area L of the mobile station MS.
No. 1 is recognized. If the mobile station MS moves to the radio zone R21 during a call, the radio zone is switched, and the fixed network NW recognizes the area in which the position of the mobile station MS is to be registered as L2. This is because, for example, in the fixed network NW, the wireless zones R11 to R13, R21 to R2
3 and a management table indicating the relationship between the location registration areas L1 and L2.

局ＭＳに送出される信号に位置情報を相乗りさせる。When the mobile station MS ends the call in the radio zone R21, the fixed network NW and the mobile station MS execute a disconnection sequence via the radio base station in the radio zone R21. In the present invention, the position information is piggybacked on a signal transmitted from the fixed network NW to the mobile station MS.

認信号を送出し、切断シーケンスを完了する。FIG. 2A shows a sequence in which disconnection is started from the mobile station MS. First, the mobile station MS sends a disconnection signal indicated by CC1 to the fixed network NW. When receiving the disconnection signal CC1, the fixed network NW sends a release signal indicated by CC2 to the mobile station MS. Upon receiving the release signal CC2, the mobile station MS sends a release completion signal indicated by CC3 to the fixed network NW. When the fixed network NW receives the release completion signal CC3, it transmits a radio channel disconnection signal indicated by RC1 to the mobile station MS. This signal carries the location information of the mobile station MS as additional information. Thus, the fixed network NW
Notifies that the mobile station MS has been registered in the location registration area L2. In the mobile station MS, the radio channel disconnection signal RC
Upon receipt of 1, the location registration information contained therein is fetched, and a radio channel disconnection confirmation signal indicated by RC2 is transmitted to the fixed network NW to complete the disconnection sequence.

CC2 'indicates a release signal, and CC3' indicates a release completion signal. The signal directions of the signals CC1 'to CC3' are opposite to those of the signals CC1 to CC3 in FIG. Also, the fixed network NW sends out the radio channel disconnection signal RC1 including the position information after a lapse of a predetermined time after sending out the release completion signal CC3 '.
