BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication system comprising a plurality of mobile stations, a base station, and a switching center that controls calls between them. Mobile communication systems in recent years are
Due to the lack of channels (lack of frequencies) associated with the rapid increase in the number of subscribers, problems have arisen in which calls cannot be made smoothly from callers and calls cannot be received smoothly by called parties. Therefore, if the calling party is always able to make a call at a predetermined reserved time, or if the channel cannot be acquired or the called party is busy, the calling party will be able to make the call without having to dial again. It is necessary to improve operability by automatically retrying at a specified time.

0002

[Prior Art] In conventional mobile communication systems, in areas where many mobile devices that have subscribed to the system are concentrated in one area and communication channels are frequently used, there is a shortage of channels (lack of frequencies) when the mobile devices want to make a call. There were times when I couldn't make calls. In addition, even if the mobile device is able to acquire a communication channel, if the called party's telephone is busy, you may have to dial again or automatically call the other party's telephone when the other party's call ends. By using camp-on processing, which allows calls to be made using a remote control, it has been possible to communicate with the other party.

0003

[Problem to be solved by the invention] In the above conventional technology,
Even if the caller attempts to establish a call using the camp-on processing described above while the called party's phone is busy, it is unknown when the called party will end the call and the camp-on processing will be performed. 1. If a camp-on process was performed while the caller was away from the mobile device, the caller had no way of knowing whether the caller had been processed or not. Furthermore, even if the called party's telephone responds to the call, if the user of the calling party's mobile unit is not present, the called party may be confused.

[0004] The first object of the present invention is to make it possible to make a call at the reserved time by reserving a scheduled call time in advance, even in areas where mobile phone call channels are frequently used. The second purpose is that when the caller leaves the mobile device at the reserved time and returns later, the mobile device makes a call and there is an incoming call, but the caller is not present. The third purpose is to enable the caller to later receive a message informing them of the cancellation, and the third purpose is to make a call to the called party when the caller is away from the mobile device at the reserved time. The purpose of this is to make it possible to notify the current status of a person (absence due to being away from the mobile device).

[0005]
