Abstract: A portable telephone radio unit is disclosed which allows a user to recognize an incomplete state of data communication which occurs with a terminal equipment because of deterioration of the communication state by radio wave interference upon channel changing over in the course of a standby channel selection operation or during communication. A signal processing section performs information analysis of a signal selected by a control circuit section from among reception signals of an antenna whose levels are measured by a radio circuit section upon channel changing over in the course of a standby channel selection operation or during communication. The control circuit section detects loss of frame synchronization, deterioration in bit error rate, unfavorable reception of broadcast information or interruption of radio waves which is a condition of radio wave interference.

Abstract: A card verification system in which a card identification code is registered. A read unit reads the card identification code from the card. A verification apparatus verifies the card only when an existing place of the read unit belongs to an area corresponding to the card identification code. The card is a card used for settlement, and is used when the card identification code is read by the read unit. The use place of the card is coincident with the existing place of the read unit. By adding the use place of the card to a verification condition of the card, unjust use of the card can be prevented.

Abstract: A card verification system is composed of a card in which a card identification code is registered. A read unit reads the card identification code from the card. A verification apparatus verifies the card only when an existing place of the read unit belongs to an area corresponding to the card identification code. The card is a card used for settlement, and is used when the card identification code is read by the read unit. The use place of the card is coincident with the existing place of the read unit. By adding the use place of the card to a verification condition of the card, unjust use of the card can be prevented.

Abstract: A card information of a card 11 to be settled is read by a payment processing terminal 12 and sent to a card authentication and settlement processing device 13. The card authentication and settlement processing device 13 calls a mobile station 21 of an owner of the card through a mobile phone mediating server 3 by using a card information of the card. By inputting a password and a settlement information from the mobile station 21, the card authentication and settlement processing device 13 performs a payment settlement.

Abstract: The present invention makes a request for location registration inhibition at a key pad portion which is manipulated by an user of a mobile radio telephone. A first memory stores the inhibition request therein, and a display displays the inhibition request. A controller does not control (i.e., does not cause to be generated) a request for location registration with respect to the base station even though the user of the mobile radio telephone moves between registered location areas when the inhibition request is stored in the first memory.

Abstract: A digital portable telephone apparatus with a holding function normally has a VOX function and previously notifies, when absence of sound is detected in a sound presence condition, transmission power off of the talking channel by way of a postamble signal. The postamble signal is sent out periodically during a sound absence period and includes mobile station background noise generation information. Holding tone data which are the same data in successive sound sampling times are incorporated into the background noise generation information, and a resulted signal is transmitted. Accordingly, the transmission time of holding tone may be intermittent, and the transmission power can be saved.
