In a communication service system for a car phone device called ``obilePhone 5 service'', 1
It is permitted to register multiple phone numbers on one car phone device. Therefore, for example, users can register their telephone numbers according to their service areas, thereby reducing call charges.

By the way, if you register multiple phone numbers like this,
At the time of use, the user manually sets one of these telephone numbers.

However, the incoming call signal for a car phone device with multiple phone numbers registered in this way is only one set as described above.
If there is no phone number, the call will not be received. Therefore, a caller to such a car telephone device must make calls using different telephone numbers one after another until the call is established. Further, if there is a phone number that the user does not know, it may be impossible to make a call.

(Problem to be Solved by the Invention) In a car phone device in which a plurality of telephone numbers are registered in this way, incoming calls cannot be received unless the incoming call signal is from one phone number set manually by the user. A caller to the device must make calls to different telephone numbers in sequence until the call is established. Also,
If there is an unknown telephone number, it may be impossible to make a call.

Therefore, an object of the present invention is to provide a mobile station device that can receive calls from any of a plurality of registered telephone numbers.

[Structure of the Invention] (Means for Solving the Problems) A mobile station device of the present invention includes a telephone number storage means for storing a plurality of registered telephone numbers, and when an incoming call signal is sent from a base station, A telephone number extracting means for extracting a telephone number included as information in the incoming call signal, and a telephone number extracting means for extracting a telephone number included as information in the incoming call signal; and a call reception means for receiving a call based on the telephone number extracted by the telephone number extraction means when the determination means determines that there is a match. It is.

(Function) In the present invention, first, a plurality of registered telephone numbers are stored. Then, when an incoming call signal is sent from the base station,
The telephone number included as information in this incoming call signal is extracted, it is determined whether or not this telephone number matches a registered telephone number, and when it is determined that there is a match, the call is received.

Therefore, a call can be received from any of the plurality of registered telephone numbers.

(Example) Hereinafter, details of an example of the present invention will be described based on the drawings.

First, AMPS used by the car phone device of this embodiment
This section provides an overview of the communication service system called .

AMPS uses a small zone system called a cell.

One service area is constructed by collecting a plurality of such cells. Each cell is provided with a base station connected to the public network via a control station and a switching center, and each mobile telephone device forms a radio link with this base station. The wireless line includes a communication channel for exchanging audible signals, that is, a conversation, between the mobile phone device and the base station, and a control channel for exchanging control signals.

Control channels include a D channel, a P channel, and an A channel. The D channel is for transmitting system information from the base station to the mobile telephone device. The initial start-up of the car telephone device is performed by the system information contained in this D channel.

The P channel is for transmitting system information and incoming call signals from the base station to the mobile telephone device. The A channel is for transmitting system information and communication channel designation signals from the base station to the mobile telephone device, and for transmitting calling signals and incoming call response signals from the mobile telephone device to the base station. That is, the car telephone device receives the P channel in the standby state, and when it receives an incoming call signal for its own station, it sends an incoming call response signal to the base station via the A channel.

Thereafter, when receiving a call channel designation signal from the base station via the A channel, the mobile phone receives a call on the designated channel in the same way as a normal telephone. On the other hand, when making a call, the mobile telephone device sends a call signal to the base station via the A channel. Thereafter, when it receives a call channel designation signal from the base station via the A channel, it makes a call on the designated channel in the same way as a normal telephone.
