Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication device such as a mobile phone and a mobile terminal device, a telephone, a personal computer, a facsimile, and a communication connection device for connecting them to enable communication.

[0002]

2. Description of the Related Art Due to the liberalization of sales of mobile phones and the introduction of a sell-out system, mobile phones have expanded explosively.
Under such circumstances, as a protocol for realizing communication, individual communication protocols such as a mobile phone based on an analog system and a digital system, a simple mobile phone (hereinafter referred to as “PHS”), and a unique protocol for each. There are communication methods with the characteristics of.

A communication procedure will be described below with reference to FIG. 3 using PHS as an example.

Communication using a portable communication device includes a telephone call that conveys the content of a talk, data communication, and the like, but these are collectively referred to as "communication" below.

FIG. 3 shows the relationship between the PHS terminal 1 and the communication connection device in PHS.

When calling the telephone 6 of the general subscriber from the PHS terminal 1, first, the telephone number of the general subscriber is dialed at the PHS terminal 1. The signal from the PHS terminal 1 is PH
When reaching the PHS connection device 3 via the S base station 2 (hereinafter, referred to as "base station 2"), the PHS connection device 3 sends an identification number (indicated whether or not the caller is a contractor). Hereinafter, it will be referred to as "ID"). If it is a subscriber, it is connected to the telephone 6 of a general subscriber through the exchanges 4 and 5.

The above-mentioned exchanges 4 and 5 are local exchanges or long-distance exchanges.

When calling the PHS terminal 1 from the telephone 6 of a general subscriber, first, the terminal number of the PHS terminal 1 is dialed. The PHS numbering system starts with 050 for identifying whether or not the service is available for communication, and consists of a two-digit number for identifying a carrier and a five-digit subscriber number.

The exchange 5 on the originating side inquires through the common signaling network 8 the PHS service control station 7 for position information necessary for exchange connection such as in which position registration area the PHS terminal 1 being called is in. Based on such location information, the PHS terminal 1 tracks and connects where it is currently,
The PHS terminal 1 is called from the base station in the corresponding location registration area.

Here, the PHS service control station 7
It is possible to store position information necessary for exchange connection, such as in which position registration area the S terminal 1 is located, and the storage procedure of such position information will be described below.

[0011] The PHS terminal 1 receives the position information reported from the base station, and if the position information is different from the stored position information, the PHS terminal 1 automatically operates in a base station in the wireless zone in which it is located, for example, the base station 2. Sends a location registration signal to. The signal is received by the base station 2, reaches the PHS service control station 7 via the PHS connection device 3, and the position information is stored.

The communication frequency band between the PHS terminal 1 and the base station 2 is a high frequency band of 1.9 GHz band in which the power loss of frequency is large. Therefore, in the PHS, communication is enabled by installing a low power base station every 100 to 200 meters instead of covering the small communicable area 9 with a low output. On the other hand, in the case of a mobile phone, due to the high power output, the range in which radio waves fly is as wide as 2 to 7 km.

For this reason, the PHS has the advantage that the usage fee is lower than that of the conventional mobile phone, that it can communicate normally even in the underground or in the building, which is difficult to access with the mobile phone, and the data transmission capacity is larger than that of the mobile phone. It has the disadvantage that it cannot be used in high-speed moving bodies such as cars and trains like telephones.

[0014]

As is apparent from the above description, the conventional portable communication device has a plurality of communication protocols because only one communication function using one protocol is provided in one portable communication device. In order to perform communication using, there is a problem that a plurality of mobile communication devices corresponding to these must be owned.

For example, when communication is performed by PHS based on a certain communication protocol while moving in an automobile or the like, and the communication is cut off due to deviation from the reception range of the base station, the communication is interrupted again. Needed to call back using a different communication protocol, eg a mobile phone.

Further, when the call is redone as described above, if the telephone of the other party who is in communication is in an off-hook state, it is considered as busy and the line is not connected. there were.

[0017]

Therefore, the present invention has been made in view of the above problems, and is characterized in that a plurality of communication functions corresponding to different types of communication protocols are provided in the same housing. To do.

The present invention is characterized by comprising a selection unit for selecting a communication function corresponding to one communication protocol from the plurality of communication functions.

The feature is that the communication with the communication partner is continued using different communication protocols.

According to the present invention, when communication using a communication protocol during communication becomes impossible, a communication protocol different from this is used to automatically call back the communication partner to perform communication. It is characterized by continuing.

According to the present invention, in a communication connection device having an exchange for controlling connection of a communication line, when the communication using a communication protocol during communication becomes impossible, the exchange is a communication partner. If it is determined whether the mobile communication device has a communication protocol different from the communication protocol with which the mobile communication device was communicating, and the mobile communication device of the communication partner has the communication protocol, the communication is performed. The feature is that communication is continued using a protocol.

There is an effect that communication can be automatically continued using a communication protocol, for example, a mobile phone, and the time when conversation or the like is interrupted can be minimized.

Further, even when the communication is disconnected, the line is in the connection hold state, and if there is a request for connection by the different communication protocol 11b during the hold state, the line is connected until the communication is cut off. Based on the ID related to the mobile communication device 10 included in the communication protocol 11a, the communication protocol 11a and the communication protocol 11b are determined to be transmitted from the same mobile communication device, and the communication protocol 11a is transmitted from the same mobile communication device. If so, connect the signal exchange switch 23b to the communication protocol 11b side,
In order to continue the communication, even if the telephone of the other party during the communication is off-hook, the line is connected as it is, and the communication can be continued.

Further, even if the communication is disconnected, the line is in the connection hold state, so that even if the data communication is interrupted in the middle of the transmission, the data can be continuously transmitted using the different protocol. Therefore, there is no need to send the data again from the beginning.
