JPH04250727A - Portable telephone set with talking function - Google Patents

Abstract

PURPOSE:To recognize the presence of a base station automatically through the senses in a vehicle or in a city by devising the portable telephone set such that the portable telephone set automatically informs its availability when the portable telephone set reaches the inside of the service area of the base station. CONSTITUTION:The portable telephone set is provided with an antenna 9 receiving a communication signal representing the communication availability range in the service area of a base station. Moreover, a light 7, a buzzer 8 and a liquid crystal display section 5 displaying when the antenna 9 receives the communication signal representing the available communication of the base station are arranged on the front surface of the portable telephone set 1. Furthermore, a vibrator 10 including an eccentric drive motor in interlocking with the antenna 9, activated when the antenna 9 receives the communication signal representing the communication enable range of the base station and vibrating the telephone set 1 itself is removably provided to the lower part of the portable telephone set 1. Thus, whether or not the vehicle is resident in the service area of the base station is recognized by the light 7, the buzzer 8 or the vibrator 10 without seeking the base station while the vehicle is driven.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] This invention relates to a telephone system that uses low-power cordless telephones, and when a low-power mobile phone whose usage range is limited, it automatically This invention relates to a mobile phone with a reporting function that notifies people that the mobile phone is available for use.

0002

[Prior Art] The second generation cordless telephone system is centered around a base station that is connected to a public telephone line and installed on a public telephone booth or building. It has been developed so that you can call a predetermined landline phone and make a conversation. This telephone system is a micro cell system in which a service area with a radius of approximately 150 meters is set around a base station, and is considered as a system that expands the range of use of personal mobile phones. In other words, this telephone system is an evolution of the usage pattern of cordless telephones, and has a common interface to communicate with multiple connection devices (base stations). Not only can it be used in places, but also
This system is configured so that by carrying a terminal device of these cordless telephones, communication can be performed in a building or on the street via a base station connected to the PSTN or ISDN.

0003

[Problems to be Solved by the Invention] However, in conventional telephone systems, when used in a car, for example, the cell radius is narrow, making it difficult to use the mobile phone that is being carried while driving. I can't. Therefore, you have to search for a base station from inside your car, park your car within the service area of that base station, and use your mobile phone, but it takes time and effort to search for a base station, which is extremely inconvenient. Become. Furthermore, on rainy days, the field of view from inside the car is limited, so there is the inconvenience of having to get out of the car and look for the base station. In addition, if a mobile phone owner wants to use a mobile phone in town, for example, the owner of the mobile phone should search for a base station in town, confirm that he/she is within the service area of that base station, and then use the mobile phone. Since it requires the use of a telephone, there are problems in terms of usability. The present invention has been made in order to solve the above problems, and its purpose is to make it possible to automatically know the presence of base stations through the five senses while in a car or on the town, and to provide versatility in mobile phones. The purpose of this invention is to provide a mobile phone with a reporting function that can expand the number of users.
