Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for restricting incoming calls of a mobile terminal, and more particularly to a manner of controlling the use of a mobile terminal in a train or a communication restriction for ensuring safety of a driving operation of a car.

[0002]

2. Description of the Related Art In a mobile communication system, there is an invention described in Japanese Patent Application Laid-Open No. Hei 7-23455 as a system for realizing incoming call control of a mobile terminal in a high-speed vehicle. FIG.
Is a conceptual diagram of the configuration of this conventional system. In the figure,
A plurality of radio base stations (CS) 2 are connected within the mobile switching system 1, and each radio base station 2 has a radio area controlled by its own base station (area indicated by a circle in the figure). It is assumed that a track or road 3 running straight through these wireless areas is running.

When the mobile terminal is fixed, reference numeral 10 denotes a high-speed in-vehicle mobile terminal (hereinafter simply referred to as a mobile terminal). The radio base station 2 constantly transmits a radio wave, and the mobile terminal 10 that has received the radio wave performs position registration in the radio area. The result of the location registration is notified from the radio base station 2 to the mobile switching system 1.

[0004] As a result, when a call is received from the outside to the mobile terminal 10, the mobile switching center 1 terminates the call to the wireless base station 2 whose location is registered, and moves via the wireless base station 2. The terminal 10 receives an incoming call. As a result, the mobile terminal and an external subscriber can make a call.

When the mobile terminal is moving at high speed In this case, the mobile terminal 10 receives a location registration start signal from the mobile switching center 1 via the radio base station 2, and stores the location registration number stored in the mobile terminal 10 itself. If the location registration numbers are different, high-speed movement detection means in the mobile terminal, which requests location registration to the mobile switching device 1 and detects whether or not the mobile terminal 1 has moved in an area of a predetermined number of radio areas or more within a certain time, If it is determined that the mobile switch 1 is moving at a high speed, the mobile switch 1 is requested to stop the location registration during an arbitrary set time. That is, the mobile terminal 10 imposes incoming call restriction on the mobile exchange 1. The reason why the incoming call is restricted in this manner is that during high-speed movement, it is necessary to perform a position registration operation for changing the wireless area one after another, and it is impossible to make a reliable call.

[0006] When the mobile exchange 1 receives a location registration request from the mobile terminal 10, it stores the location registration number of the wireless area in a table, and further receives a location registration request stop signal from the mobile terminal 10. And that the corresponding mobile terminal 10 is stopping location registration (moving at high speed), and when there is an incoming call to this mobile terminal 10, the mobile terminal 10 is moving at high speed with respect to the source. To notify you.

[0007]

In the incoming call restriction system in a high-speed vehicle of a mobile terminal of a mobile communication system as described above, the mobile switching center 1 determines that the mobile terminal 10 has shifted from high-speed movement to low-speed movement, There is a problem that it takes a long time to recognize that, and a delay in canceling the incoming call restriction occurs. Further, there is a problem that a user having an existing mobile terminal having no function such as a high-speed movement detection means cannot receive the incoming call barring service. Further, there is a problem that there is no guarantee that incoming call regulation is reliably performed in a train and a high-speed car.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is possible to reliably control incoming calls during high-speed movement, and to immediately release incoming calls when high-speed movement becomes low-speed movement.

When the mobile terminal is no longer in use, by canceling the incoming call regulation, it is possible to detect that the mobile terminal is moving at a low speed instead of moving at a high speed, and cancel the incoming call regulation for the mobile terminal.

(5) Further, by providing a memory in which names of tracks and roads laid in the radio area indicated by the location registration number are provided in the mobile exchange, the mobile exchange can indicate the location registration number. It is possible to grasp the state of the tracks and roads laid in the wireless area.

As described above, according to the present invention, the incoming call restriction can be reliably applied during high-speed movement, and the incoming call restriction can be quickly released when the high-speed movement becomes low-speed movement. A system can be provided.
