    摘要: A wireless communication system capable of communicating by a frequency hopping method, includes a base unit that can be connected to an external telephone circuit and multiple handsets that can communicate wirelessly with the base unit. A hopping table of the base unit stores a hop frequency data array B for communications between the base unit and a selected handset. A hopping table of each handset stores hot frequency data arrays H1 and H2 for communications between two handsets in addition to the hop frequency data array B possessed by the based unit. During communications between the base unit and a handset, communications between handsets are possible by using the hop frequency data arrays H1, H2.

    摘要: Message information to be transmitted to a cellular phone set is stored and the cellular phone set is called by using a short distance telephone number. If the line cannot be connected, the short distance telephone number is changed to a long distance telephone number and the cellular phone set is called again. When the line is connected, the stored message information is transmitted. Even when a user of the cellular phone set is located at a long distance area, the message information is transmitted by automatic redialing.

    摘要: The present invention provides a time setting system and method thereof that are capable of correctly setting time if a delay occurs in the transmission of time information. In the system for setting a master time outputted from a master apparatus to a slave time of a slave apparatus that counts time independently of the master apparatus, the slave apparatus has transmission section for transmitting master time request information to the master apparatus via a network and the master apparatus has an allowable range information acquisition section for acquiring allowable range information indicative of an allowable time in which the master time may be set to the slave time of the slave apparatus and transmission section for transmitting the master time and allowable range information to the slave apparatus. The slave apparatus obtains a time difference between a first slave time to be obtained before or after the transmission of master time request information and a second slave time to be obtained at reception of the master time and the allowable range information. If the allowable time is greater than the obtained time difference, the master time is set.
