DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile telephone switching system, and more particularly, to a mobile terminal when a call is originated, for example, notification of wireless communication channel acquisition waiting order information and channel vacancy information. The present invention relates to a mobile radio telephone method and a mobile terminal having a display function and a mobile terminal.

[0002]

2. Description of the Related Art Conventionally, in a mobile telephone switching system, when a wireless communication channel cannot be captured because the mobile terminal is in full use at the time of calling, the mobile switching equipment sends a call to the mobile terminal (subscriber). On the other hand, there has been proposed a technique for notifying a time until a wireless communication channel can be captured, a waiting order, and the like.

For example, in the mobile telephone switching system described in Japanese Patent Application Laid-Open No. 1-189240, the switching system transmits a queuing time when the call wireless channel is busy during a call from a mobile terminal. By displaying the message on the display of the mobile terminal and automatically starting the outgoing connection after the waiting time, the caller does not needlessly repeat the call, and the switch side also performs the retry. This is to prevent confusion caused by the call phenomenon.

Further, the waiting order display method for a mobile communication terminal described in Japanese Patent Laid-Open No. Hei 6-97879 discloses a method of queuing a terminal on the subscriber side which cannot enter a communication channel and is in a standby state. This is a system that displays whether the call is being made, thereby enabling prediction of the time until it is assigned to the communication channel.

[0005]

In the above-mentioned method, the information that can be obtained by the attendant using the mobile terminal is limited to the time until the wireless communication channel can be captured and the order of waiting. However, there is a drawback in that mobile telephone participants can simply wait for the wireless communication channel to become available. Also, since the subscriber moves, there is a possibility that the mobile terminal may move to another area in the wireless communication channel capture waiting state, or the power may be turned off. It was not possible for the switching system to provide actual information near real time.

SUMMARY OF THE INVENTION An object of the present invention is to provide a mobile radio telephone method capable of always providing a subscriber using a mobile terminal with the latest radio communication channel acquisition waiting information and channel acquisition waiting registration information for each area. Another object of the present invention is to provide a mobile terminal and a mobile switching center capable of implementing such a method.

[0007]

According to the mobile radio telephone method of the present invention, in the mobile radio telephone method of the area division system, when the mobile exchange cannot capture the radio communication channel at the time of calling the mobile terminal, the mobile radio telephone is not used. The terminal is registered as a channel capture wait state, and the channel capture wait order information at that time and the channel capture wait registration information for each area are transmitted to the mobile terminal to be displayed. Further, the mobile terminal receives the channel capture waiting order information and the channel capture wait registration information for each area from the mobile exchange, and displays the information on a display unit,
A reception response is transmitted to the mobile exchange. The mobile switch, when a reception response from the mobile terminal is received, transmits to the mobile terminal the channel capture wait order information at the time of reception and the channel capture wait registration information for each area,
When the reception response is not received, the channel release wait is released.

A mobile terminal according to the present invention is a mobile terminal used in a mobile radio telephone system of an area division system. Display means for displaying registration information for each channel acquisition wait; In addition, the mobile exchange has a transmission means for receiving a response to the reception of the channel acquisition waiting order information and the channel acquisition waiting registration information for each area from the mobile exchange.

Further, the mobile exchange according to the present invention is a mobile exchange used in a mobile radio telephone system of an area division system, and cannot capture a radio communication channel when receiving a call from a mobile terminal. When storing the mobile terminal as a channel capture waiting state,
And transmitting means for transmitting to the mobile terminal channel capture wait order information and channel capture wait registration information for each area at the time of calling and receiving response of the mobile terminal.

[0010] The mobile exchange can always transmit the channel waiting order and the channel availability information for each area to the mobile terminals that are in a state of waiting for the latest wireless communication channel.
Since it is possible to confirm the location of the mobile terminal in the channel acquisition waiting state, unnecessary queues are eliminated, and the user of the mobile terminal acquires the latest channel acquisition waiting order and channel information of the neighboring area. It is possible to talk by actively moving to an area where the wireless communication channel is free.
