BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adapter system for wired connection of mobile devices, and, for example, to application to wired connection of conventional mobile phones and the like.

[0002]

2. Description of the Related Art In recent years, mobile phones have become popular. For example, as a telephone service using a mobile phone,
For example, there are those by DoCoMo of NTT Central Mobile Communications Co., Ltd. and those by Japan Mobile Communications (IDO). According to these mobile phone services, it is possible to wirelessly make a call with a general telephone of a conventional public telephone network, an international call, or a call with a car telephone.

The spread of mobile phones as described above requires that they be used in the same way as the wired public phones that have been conventionally used in homes, and the technical development for such needs is parallel. It is thought that it is being used as a portable device because it was carried out.

For example, current mobile phones are small and lightweight, and are made convenient through a wireless telephone line when traveling or going out.

[0005]

However, even now, requests for improvement have been proposed from various viewpoints. For example, in general, when a user returns to a home or office from outside, the battery is attached to a charging adapter and placed on a desk so as to charge the storage battery of the mobile phone. In such a case, for example, in some cases, an existing wired home telephone,
The mobile phone and the charging adapter may be placed on the desk in a mixed state. In such a case, since the mobile telephone also communicates the home telephone with the subscriber telephone of the conventional public telephone communication network, there is a demand that the necessary public telephone communication can be performed with as little equipment as possible.

[0006] In addition, the mobile phone is generally different from the conventional home phone in the operation method, and since it is a phone capable of a new form of wireless communication, it is easy for a user who is using it for the first time to be confused. .

For example, the speed dial number information of a mobile phone can be stored in a storage unit in the mobile phone, but the method of reading this speed dial number information is different. Further, specifically, since the numbers and the order of the storage locations do not match those of the home telephone, it is not so easy to operate as compared with the operation of the conventional home telephone. Therefore, there is an inconvenience in the method of operating the mobile phone.

Achieving the above-mentioned demands and improving the above-mentioned problems are very important issues from the viewpoints of realizing social life effectively and effectively using resources. Is believed to be.

From such a point of view, for example, when a user who is a subscriber wants to use it at home by subscribing to a mobile phone, it is connected to the line connection terminal of the conventional public telephone network by some means. If it is possible, it is not necessary to own both the mobile phone and the home telephone as long as there is a mobile telephone that can be used like a conventional wired home telephone. Moreover, if this is possible, a user who has a contract for a mobile phone may be able to use it as a mobile phone when going out and as a wired phone at home.

If such a thing becomes possible, it is possible to make effective use of the equipment, and to connect to a wired line to make a necessary call in an environment where radio wave propagation conditions are incapable of making a radio wave call impossible. Is possible. Further, economically, the line usage fee may be cheaper when using the wired line than when using the wireless line at present, and therefore, it is required that the use can be selected.

The present invention has been made in view of the above problems, and an object thereof is to connect a wireless mobile device such as a conventional mobile phone to a wired line with a simple structure. An object is to provide an adapter system for mobile device wired connection.

[0012]

In order to achieve the above object, the present invention has been realized by the following characteristic constitution.

That is, a mobile device (for example, a mobile phone) capable of wireless communication with a base station of the public communication network outputs information or a call signal for calling the other party, or a wired line of the public communication network. Wired connection interface means for receiving and outputting the signal from

Further, first connection means for making a connection for exchanging signals with the mobile unit, and second connection means for making a connection for exchanging signals with the wired line side. When the information for calling the other party is given from the first connecting means, it is converted into a line signal for calling the other party for connecting the wired line and output to the wired line through the second connecting means, or the first line. When the transmission signal is given from the connection means of No. 2, the signal is output to the wired line through the second connection unit as a line transmission signal for connecting the wired line, or is supplied from the wired line through the second connection unit. And an adapter means for causing the wired connection interface means to apply the detected signal to the wired connection interface means through the first connection means.

[0015]

According to the present invention, when the mobile unit wants to call the other side through the wired line, the necessary call information or the transmission signal is output from the wired connection interface means of the mobile unit and given to the adapter unit. be able to.

Further, the necessary calling information or transmission signal from the wired connection interface means of the mobile unit is converted into the calling side call line signal suitable for the wired line by the adapter means and the second connection is made. It can be output to a wired line through the means. Further, when a transmission signal from the wired connection interface means of the mobile unit is given through the first connection means, the adapter means forms a line transmission signal suitable for connection to a wired line and the line transmission signal is generated. It is possible to output to a wired line through the second connecting means.
