Abstract

PROBLEM TO BE SOLVED: To inform a mobile station about the arrival of an incoming call by sending a call signal and a telephone number of a caller subscriber to the mobile station moved at the outside of a radio wave arrival range after position is registered in the radio wave arrival range of the radio base station from a high output call radio base station with a wide radio wave arrival range provided separately. SOLUTION: The system is installed with a high output call radio base station 5 providing a high output call area covering a range in excess of a plurality of call areas 7 and an outer ridge of the service area. The high output radio base station 5 acts as a call exclusive base station and sends a call signal to call a mobile station returning no reply even in the case of a call to the area whose position is registered and a subscriber number making the call. The mobile station 9 receiving the call signal returns to a speed available area and makes a call to the displayed subscriber number for speech. Moreover, a plurality of the radio base stations 4 in the high output call area receive a reference synchronizing signal from the high output call radio base station 5 so as not to be interfered with the transmission signal from the high output all radio base station 5, and sends a signal to the station 5 synchronously with the base station 5.

2. Description of the Related Art A PHS for performing mobile communication in a communication area composed of a plurality of microcells comprises a mobile communication switching center, a plurality of radio base stations connected thereto, and a subscriber terminal. Within the range of radio waves, PH
This is a system in which a call can be made by calling from an S subscriber terminal and receiving a call from a general telephone subscriber. Of course, a call from a PHS subscriber terminal to another PHS subscriber terminal is also possible. PH
The S subscriber terminal normally sends a location registration signal to the system when the power is turned on or when the mobile terminal moves through a paging area in which the plurality of base stations are grouped, so that the home subscriber terminal installed in the mobile communication switching center can be used. Registered in a location register (subscriber location storage device), the system always recognizes the location of the subscriber terminal.

When a general telephone subscriber calls a PHS terminal subscriber, the telephone number of the called PHS subscriber terminal is sent to the general telephone network. The general telephone network recognizes from the received telephone number that it is a PHS subscriber, and notifies the mobile communication switching center of the called PH.
Send the telephone number of the S subscriber terminal. In the mobile switching center, the telephone number of the called PHS subscriber terminal received from the general telephone network is referred to the home location register.
It confirms in which calling area the HS subscriber terminal is composed of a plurality of radio base stations, and sends a call signal of the called PHS subscriber terminal to the plurality of radio base stations constituting the paging area.

[0004] Each radio base station in the paging area converts the paging signal of the called PHS subscriber terminal received from the mobile switching center into radio waves and radiates them. The called PHS subscriber terminal detects a calling signal radiated by the radio base station in the communication area where the called PHS subscriber terminal exists, and after confirming that the calling is to the self,
The response signal is sent back to the wireless base station. This response signal is sent to the mobile communication switching center via the radio base station, and connects the general telephone subscriber calling at the mobile communication switching center to the called PHS subscriber terminal to enable mutual communication.

[0005] On the other hand, if the PHS subscriber terminal moves outside the radio wave coverage area after registering its location within the radio wave coverage area from the radio base station, the call from the ordinary telephone subscriber is sent to the radio base station. The call signal from the station does not reach the PHS subscriber terminal, and a call cannot be made. In this case, the mobile communication switching center notifies the general telephone subscriber that the called PHS subscriber terminal is out of radio waves or has been turned off, and that the calling cannot be performed.

In some cases, a paging system is also used to call a PHS subscriber terminal that has moved out of the range of radio waves. That is, if a PHS subscriber terminal moves out of the radio wave coverage area after performing location registration within the radio wave coverage area from the radio base station, a call from a general telephone subscriber will be issued from the radio base station. Since the paging signal does not reach the PHS subscriber terminal and there is no response, the paging signal is transmitted from the mobile communication switching center to the paging system switching station, and the paging system radio base station transmits the paging signal.

In a mobile communication system such as a PHS, since the transmission output of the radio base station and the PHS subscriber terminal is small, the range of radio waves from the radio base station is only about 100 m to 200 m. There is a high possibility that the PHS subscriber terminal easily goes out of the range of radio waves. For this reason, many radio base stations are installed in the PHS service area, and the radio wave coverage of these radio base stations is sufficiently overlapped to reduce the area where radio waves do not reach. In many cases, radio waves do not reach sufficiently behind buildings and underground shopping malls. Therefore, if a PHS subscriber terminal moves out of the radio wave coverage area after performing location registration within the radio wave coverage area from the radio base station, a call from a general telephone subscriber will not be transmitted from the radio base station. There is a problem that the call signal often does not reach the PHS subscriber terminal and the call cannot be made.
