Abstract

PROBLEM TO BE SOLVED: To reduce the power consumption of a mobile station in a call signal standby state by allowing a receiver of a private mobile telephone system to receive a call signal from a mobile communication network, informing it to the mobile station and allowing the mobile station to send a reply signal directly to the mobile communication network being a caller. SOLUTION: Upon the receipt of a call signal Pch from any of plural mobile communication networks 100, a receiver 3 of a private mobile telephone system 1 detects the presence of a call signal in the Pch addressed to a mobile station 6. When the call signal is in existence, the receiver 3 adds identification information of the communication network 100 being the caller to the call signal and sends the resulting signal to a CPU 5 of an exchange 2. The CPU 5 selects a proper base station 4 and sends a call signal to the mobile station 6 registered in advance and allows the mobile station 6 to send a reply signal directly to the communication network being the caller. Thus, it is not required for the mobile station 6 to await the Pch from the communication network and the mobile station 6 reduces its power consumption in the standby state and then the operation available time of a power supply battery is extended.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile station capable of connecting to and communicating with a plurality of mobile communication networks, such as a public mobile communication network and a private mobile telephone system, from any given communication network. The mobile communication receiving system which receives the call signal of the above and responds to the communication network of the calling side.

At present, commercial (public) and privately-owned mobile radio communication systems have been put into practical use. However, in the public mobile communication network and the private-use mobile telephone system, the radio frequency to be used and the control procedure are used. However, when the mobile station wants to receive the call signal from both, it can receive the call signal from any of them because the radio signals of independent radio frequencies are transmitted to the mobile station by different procedures. Similarly, it is necessary to wait for a call signal from both. The same applies when receiving call signals from a plurality of public mobile communication networks that use different radio frequencies and control procedures. At present, a digital mobile phone system (a mobile phone system based on a digital car phone system, called a PDC network) is about to become the mainstream of public mobile communication networks. Since a new mobile communication system such as a private PHS (cordless system for business establishments) is put into practical use and a plurality of mobile communication services are commercialized in parallel, a mobile station that can be connected to any network (system) is It is necessary to reduce power consumption during standby and enhance user convenience.

[0003]

2. Description of the Related Art A calling radio wave (usually called Pch) transmitted from a PDC network such as a conventional digital car telephone system to a subscriber's mobile station is defined by each network (system). At every predetermined time interval (for example, 500 ms), the data is transmitted to mobile stations within the range. Each mobile station receives the Pch from the network in synchronization with its transmission cycle, and checks whether or not the pch signal addressed to itself is included therein. When a certain mobile station waits for Pchs from a plurality of networks in parallel, it is necessary to receive Pchs from each network. Therefore, FIG. 6B is an explanatory diagram of the standby operation of the mobile station. For example, if you want to receive a call signal addressed to your own station from three networks N1, N2, and N3 that transmit Pch every 500 ms, you must receive Pch three times in every 500 ms. become. Then, as shown in the configuration diagram of the conventional example of FIG. 6 (a), the pch of the call received by the mobile station 6 from a certain mobile communication network (100) includes a paging signal addressed to the own station 6. In this case, the mobile station 6 is configured to send back a response signal indicating that the paging signal has been received, to the mobile communication network 100 which is the source of the received Pch. Also, when a call signal is received from the private mobile phone system (1), a response signal indicating that the call signal has been received is similarly returned to the private system (1) of the calling source.

[0004]

In order for the mobile station 6 to receive the Pch of the calling signal from the mobile communication network (100) and the private mobile phone system (1), at least the reception moment is received. Since it is necessary to turn on the power of the machine, it consumes power correspondingly. Since there is no need to perform the receiving operation during the time when the Pch signal is not transmitted from either the mobile communication network (100) or the private mobile phone system (1), the receiver may be powered off. Therefore, the mobile station
6 is a mobile communication network (100) and a private mobile phone system (1)
The so-called "intermittent reception" is performed in which the power of the receiver is turned on only during the time when the Pch signal is transmitted from the receiver and the power is turned off during the other times.

The mobile station 6 receives P from a plurality of communication networks (100, 1).
When receiving ch signals in parallel, it takes a long time to turn on the power to receive them, and the mobile station 6 makes the mobile communication network (1
00) or the Pch signal from only one network of the private mobile telephone system (1) is received, the power consumption of the power source is increased. Therefore, when the mobile station 6 uses the battery as the power source, the receivable time (battery duration while waiting for an incoming call)
However, there is a problem in that the usability of the user of the mobile station 6 is deteriorated.

An object of the present invention is such that, when a mobile station waits for a call signal (same as an incoming signal) from a plurality of communication networks, the power consumption of the power source of the mobile station is small and the receivable time is not shortened. To realize a new mobile communication termination method.
