Abstract

PROBLEM TO BE SOLVED: To accelerate communication by monitoring the entrance into a communication area of a call termination terminal and change to a power-on state at all times and immediately reporting to a call originating station upon detecting the change. SOLUTION: When cell origination reception is present during operation standby on a service network side, in the case of the call origination to a mobile telephone, the presence/absence of the position registration of the call termination PHS terminal 12 are judged by information from a PHS service control station 50. When a position is registered and call termination reception is returned within a prescribed time, a prescribed switching call procedure is performed and the communication is started. When the call termination reception is not present, it is reported that the call termination PHS terminal 12 is on the outside of an area. thereafter, when the service of an area-in report is requested, a PHS base station 21 to which a call origination side terminal belongs receives the position registration information of the call termination side PHS terminal 12 from the PHS service control station 50, checks it at all times, and upon confirming that the call termination PHS terminal 12 enters the area, makes the area-in report to a call origination PHS terminal 11.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication system, and more particularly to a mobile communication system for performing rapid communication of a mobile communication system such as a PHS or a portable telephone.

[0002]

2. Description of the Related Art In a network service of a mobile communication system such as a PHS or a mobile phone, a communication area of a PHS or a mobile phone terminal corresponds to a radio wave arrival area, and when a receiving side is out of a communication area, or When the power is turned off, the calling side is notified by voice output that the called side is out of the communication area or the power is off.

[0003]

As described above, in the conventional mobile communication system, when the called party is out of the communicable area or when the power is turned off, the called party is given the communication area by the calling party. The caller simply provided audio guidance to indicate that he was out or was powered off,
When the called party cannot know when the called party is ready to receive a call, the calling operation must be repeated many times, which is not only inefficient, but when the called side is out of the communication area for a long time, the calling operation is performed. Therefore, there is a problem that even if the receiving side is in a communicable state, the incoming call cannot be made and quick communication is impossible.

It is an object of the present invention to provide a mobile communication system capable of performing a calling operation immediately when a called party reaches a communicable state.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a mobile communication system according to the present invention is a mobile communication system for performing communication between terminals connected via a radio wave line. When the called terminal is out of the communicable area or is in the power-off state at the time of the call, thereafter, the change of the called terminal to the communicable area state or the power-on state is monitored. Inform the calling terminal that communication is possible.

Here, the notification to the calling terminal is performed by voice, character display, or vibration.

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a flowchart showing an operation procedure of an embodiment of the present invention, and FIG. 2 is a basic configuration diagram thereof.

Referring to FIG. 2, in an embodiment of the present invention, a plurality of PHS terminals 11 and 12 are
, The PHS base station 21,
Reference numeral 22 is connected to exchanges 31, 32. Telephone 10
Are connected to the exchange 31 via a wired line. The exchanges 31 and 32 are connected to the exchange 40, and the exchange 40
It is connected to the S service control station 50. All the terminal information belonging to the service area covered by the PHS base stations 21 and 22 is collected, and the P information is exchanged through the exchanges 31, 32 and 40.
It is sent to the HS service control station 50, and the PHS service control station 50 manages the location registration information of the calling terminal and the called terminal and information for enabling communication between the terminals,
Communication between the two terminals is controlled. The operation procedure in the embodiment of the present invention described below is executed based on control signals and information transmitted and received through the PHS base station and the exchange.

The operation of this embodiment will be described with reference to FIG. First, if a call is accepted during the operation standby (step S
1) It is determined whether or not the call is for a mobile phone (step S2). This determination is made based on the first three digits of the dial transmission, for example, “050”, “030”, “010”, “080”.
And so on. If it is determined in step S2 that the call is not a call to a mobile telephone, a normal wired telephone call operation process is performed (step S3). If the call is a call to a mobile telephone, the call is output from the PHS service control station 50. It is determined whether or not the location of the receiving terminal is registered based on the received information (step S4). Here, if the location is not registered, an unregistered number (unused telephone number) is notified (step S5). If the location is registered, an incoming call is transmitted (step S6), and a predetermined number is transmitted. It is determined whether the reception of the incoming call is returned within the time (step S7). Step S
In step 7, if the incoming call reception is returned, a normal exchange call procedure is performed (step S8), and mutual communication is started. If the incoming call reception has not been returned, it is notified that the receiving terminal is out of the area (step S9).

[0010] Thereafter, a notification of the area-in notification service guide of the terminating terminal, which is a function of the present invention, is notified (step S10), and it is determined whether or not the area-in notification service is requested (step S10). S11). Here, if there is no request, a process outside the normal area (notifying that the user is out of the communicable area or that the power is turned off by voice as in the related art) is executed (step S1).
2) If there is a request, the completion of setting of the area-in notification service is notified (step S13), and then disconnection (step S13).
14) It is determined whether or not the called station has entered the area (step S15). Here, the P to which the calling terminal belongs
The HS base station always (or at regular time intervals) queries the PHS service control station 50 for the location registration information of the terminating terminal, and always performs the location registration check. In the location registration check, the originating terminal may ask the PHS base station managing the terminal at regular time intervals to check the information in the PHS service control station 50. After it is confirmed that the called station has entered the area, the calling station is notified of the area-in by, for example, character guidance or voice guidance (step S16), and the process ends.

It is to be noted that the area-in notification to the calling station can be performed by character information communication using a destination subaddress or by wire, PHS, mobile phone, business radio, or bidirectional pager using DTMF characters. Transmission of voice and text is also possible. Also, it can be notified by vibration. Furthermore, since the service network always monitors the area-in, the mobile terminal such as a PHS
Less network traffic than regular checks.

[0012]

As described above, according to the mobile communication system of the present invention, when the receiving terminal is out of the communication area or in the power-off state, the subsequent receiving terminal enters the communication area. Since the change to the power-on state is constantly monitored, and when the change is detected, the calling station is immediately notified of the change by voice or text, so that quick communication is possible.
