Abstract

PROBLEM TO BE SOLVED: To provide a private PHS system that can transmit a message denoting the absence, when a person is not in the premise. SOLUTION: In the private PHS system, consisting of a plurality of private PHS terminals, a plurality of private wireless base stations having an area that enables reception and transmission with the terminals, and an exchange connected to the wireless base stations with wired channels and connected to a public telephone line, a private PHS center periodically makes position registration between the PHS terminals and the wireless base stations, to manage the position information of the present PHS terminal, so as to predict movement of the PHS terminal. When the PHS terminal receives an incoming call and the PHS terminal is disabled of ringing or resident in an area whose calling is disabled or inhibited, PHS center predicts the behavior of the possessor of the PHS terminal from the position information and automatically replies various announcements on behalf of the PHS terminal.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a premises PHS system.

[0002]

2. Description of the Related Art A local PHS system is provided with a radio base station that covers a predetermined radio area, and enables a radio PHS terminal in the radio area to communicate via the radio base station. . One example is described in Japanese Patent Application Laid-Open No. 8-205229.

[0003]

However, in the conventional on-premises PHS system, when the receiving side is turned off or goes out, when a call comes in, only the busy tone of the busy tone sounds. there were. The problem is that the calling user does not know what the called user is doing or not at the premises.

[0004] It is an object of the present invention to solve these problems of the prior art and to provide a private PHS system capable of transmitting a message that the user is out of the office when he is not in the office.

[0005]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a plurality of private PHS terminals, a plurality of private wireless base stations having areas in which transmission / reception can be performed with these terminals, and In a private PHS system comprising a wireless base station and an exchange connected by wire and connected to a public telephone line, a private PHS center periodically performs location registration between the PHS terminal and the wireless base station to perform a current location of the PHS terminal. Predict the movement of the PHS terminal by managing the information, and predict the behavior of the PHS terminal holder from the location information when there is an incoming call at the PHS terminal and the terminal is in a place where calling is impossible or prohibited. Then, the system is configured to automatically respond to various announcements on behalf of the terminal.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. The present invention allows the location registration of the terminal PS to be performed even in the private PHS system, and stores the time and the information of the CSID, which is the ID of each radio base station CS, in the private PHS.
Save it in the center PC.

For example, when a person carrying the terminal PS goes out, the terminal PS goes out of the premises while repeating certain CSID information and location registration with each base station CS in the premises toward the exit. Will be. In such a case,
The local PHS center PC changes the CSID, which is the number of the radio base station CS indicating the area where the terminal PS is located, and the time from the last location registration to the next location registration (since the location is not registered if you go out, It is determined whether or not the user is on the premises based on the presence or absence of the next location registration). When the location registration becomes impossible after a certain period of time, the owner of the premises PHS terminal PS goes out. Then, a message such as "I'm out of the office now" is automatically sent to the calling party.

Further, since the terminal PS holder's occupancy position on the premises and the radio base station CS in that area are fixed, the path from the radio base station CS to the exit and the position registration with the movement are performed. Since the order of connection with the base station CS is constant, the behavior pattern of the owner of the PHS terminal PS is estimated and stored, so that the location-registered CSI
From D and time, the message can be sent to the other party without the owner of the local PHS terminal PS being conscious.

[0009] In addition, since movement to a conference room, a dining room, each floor, a specific place, and the like can be identified by the ID of the wireless base station CS whose position has been registered, "the meeting is being held now." Various messages such as "I'm in the middle.""I've been on the 〇Floor floor just before.""I'm in the president's office and can't connect."
The HS center can transmit.

As described above, since the location registration is performed every time the radio base station CS waiting for the terminal PS changes, the local PHS center PC changes the ID of the standby radio base station CS with respect to the subscriber number. Is stored in a memory so that can be recognized as a history. Further, the time is counted, and the behavior of the owner of the local PHS terminal PS can be estimated by the combination of the CSID and the time. Further, the radio base station CS may be arranged in the premises so that the behavior can be easily estimated.

FIG. 1 is an explanatory diagram showing the structure of the present invention.
2 shows an area in which a premises PHS system is installed. A circle around each radio base station CS indicates an area covered by the radio base station CS. When the user exits the premises, the user goes out of the area of the premises PHS system. Hereinafter, the operation of the terminal PS will be described with reference to the drawings. PS is a local PHS terminal, CS is a wireless base station, PC is a local PHS center, and 1 is an exchange. (1) The holder of the PHS terminal PS is the radio base station CS on the premises
If you are in area 1.

At this time, the location is registered in the area of the radio base station CS1, and the local PHS center PC has the location information. At the same time, it counts the time since location registration. At this time, the location registration is periodically performed even in the same area, and the time after the location registration is counted. (2) When the terminal PS holder goes out of the premises.

When going out, the radio base station CS1 → C
The location registration is repeated from S2 → CS3 → CS6 → outdoor.
The premises PHS center PC previously stores the movement pattern of the position registration of the terminal PS, and recognizes that the terminal PS has moved to the vicinity of the exit from the moved position information. The time after accessing the last CS 6 is counted, and if the location is not registered for a predetermined time or more, it is determined that “the user is out of the service area = going out”. (3) When there is an incoming call to the terminal PS while the terminal holder is out while carrying the terminal PS.

Although the terminal cannot receive the signal, the location of the terminal PS is periodically registered in advance as described above. Therefore, even if the user leaves the premises while holding the terminal PS, the premises PHS center PC is quickly activated. Since this fact is sensed, when a call is received by the terminal PS holder, a response message is automatically sent with the contents registered in advance, saying "@ is out now." In addition, if the behavior can be predicted not only by going out but also by the change pattern and time of the position information, the premises PHS center PC may judge it and send an appropriate response message.

[0015]

As described above, according to the configuration and the method of the present invention, since the location registration is performed periodically, even if the terminal holder goes out while holding the terminal, Since this can be inferred, there is an effect that the absence can be automatically answered with a response message.
