Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a radio communication means connectable to each of a plurality of radio communication networks having different radio communication systems, and the radio communication means being connected to any one of the plurality of radio communication networks. And a control unit for establishing a communication line with a communication partner by connecting the wireless communication device.

[0002]

At present, as radio communication systems applied to mobile communication, there are a cellular radio communication system represented by a portable telephone system and a car telephone system, and a second generation cordless telephone system. Developed simplified mobile phone system (PHS: Pers
onal Handyphone System).

[0003] In a cellular radio communication system, a base station (BS) has an area radius of 1.5 k.
Since the length is from m to several km (macro cell), there is an advantage that the service area is wide and communication is possible even during high-speed movement, but there is a disadvantage that power consumption is large in a mobile phone device or a car phone device. On the other hand, the simplified mobile phone system is a radio base station (CS: Cell Statio).
n) Area radius is 100m to several hundred m (micro cell)
It is small compared with the area radius in the above-mentioned cellular wireless communication system, so that there is an advantage that the power consumption is small in the simple type mobile phone device, but the service area is narrow and communication cannot be performed during high-speed movement. There is a disadvantage that.

[0004] Under such circumstances, in recent years, as a portable telephone device that can be used in both the cellular wireless communication system and the PHS wireless communication system, the functions of the cellular portable telephone device and the PHS portable telephone device are described. A mobile phone device having both functions of the simple mobile phone device of the system has been considered.

By the way, the fact that the portable telephone apparatus can be used in both the cellular communication system and the PHS wireless communication system in other words means that the portable telephone apparatus can be used in the cellular communication system. Since it is possible to connect to both the wireless communication network and the PHS wireless communication network, the user needs to select which wireless communication network to connect to when making a call. In this case, for example, a new key called a “cellular system / PHS system” key is provided in the mobile phone device, and when a user makes a call, the user operates a “numeric” key indicating a calling telephone number, and then “cellular system / PHS” key.
By operating the "HS system" key, it is possible to select a wireless communication network to be connected to.

[0006] In this case, the user is generally required to make a request when the communication carrier contracted by the communication partner is the same as the communication carrier contracted by his / her own portable telephone device. If the communication partner is a cellular mobile phone device, a cellular wireless communication network is selected and transmitted. If the communication partner is a simple PHS mobile phone device, a PHS wireless communication network is selected. It is thought that we send.

[0007] This is because the caller billing system is basically adopted as a fee system in the communication industry, and there is a situation that when communication networks having different communication systems are interconnected, the communication fee increases. Therefore, in order to reduce the communication fee, if the communication network is interconnected when the communication line is established, it is considered that the user will select the one with the smallest number of interconnections and make a call. is there.

However, in the case where the user operates the "cellular / PHS" key as described above, it is necessary to recognize whether the communication partner is a cellular cellular phone or a PHS cellular phone. ,Also,
If the communication partner does not recognize which communication carrier is contracted, there is a problem in that it is not possible to accurately select the lower communication fee between the cellular system and the PHS system. That is, if the communication method of the communication partner or the communication carrier to which the communication partner is subscribed is not recognized, there is a possibility that the user who selects the higher communication fee may be selected, and if that is the case, the economic efficiency is inferior. Become.

In this case, since the first three digits of the calling telephone number are the service identification code indicating the communication system,
By storing the service identification code, the communication method of the communication partner can be easily identified.
Since the two digits following the service identification code of the outgoing telephone number are the carrier identification code indicating the communication carrier, storing the carrier identification code makes it easier for the communication partner with whom the communication partner has contracted. In recent years, with the progress of communication technology, a number of communication systems have been developed and put into practical use, and with this, service identification codes have tended to increase, and due to the liberalization of communications, Considering the background that a large number of telecommunications carriers have entered and the operator identification code tends to increase, it is extremely difficult to store all the service identification codes and all the operator identification codes. That is the fact.

The present invention has been made in view of the above circumstances, and has as its object to provide a plurality of wireless communication networks having different communication systems such as a cellular wireless communication network and a PHS wireless communication network. It is an object of the present invention to provide a wireless communication device capable of making a call while improving the economical efficiency without having to store various codes included in a calling telephone number among those connectable to each other.

[0011]

According to the wireless communication apparatus of the present invention, when a calling telephone number is inputted, the calling telephone number identifying means identifies the inputted calling telephone number, and the control means comprises: According to the identification result of the calling telephone number identification means, when establishing a communication line, a plurality of wireless communication means are connected so that the number of interconnections is minimized when the communication networks constituting the communication line are interconnected. Connect to one of the wireless communication networks.

That is, when a user inputs a calling telephone number and a communication network constituting a communication line is interconnected according to the calling telephone number, the number of times of connection is minimized. Users will be automatically connected to the communication network, that is, the communication line will be established so that the communication fee will be minimized. There is no need to store various codes such as an identification code, and transmission can be made with improved economic efficiency.

According to the second aspect of the present invention, when the calling telephone number is inputted, the calling telephone number identifying means,
The input calling telephone number is identified, and the control means determines whether the service ID code and the business operator are included when the calling telephone number includes the service identification code and the business operator identification code. When the identification code matches the service identification code and the business identification code assigned to the wireless communication network to which the wireless communication means can be connected, the wireless communication means matches the service identification code and the business identification code. Connection to the established wireless communication network.

That is, in this system, a user inputs a calling telephone number, and at that time, a service identification code and a business identification code included in the input calling telephone number, and a wireless communication means connectable to the wireless communication means. When the service identification code and the service provider identification code assigned to the communication network match, the wireless communication network automatically connects to the service communication code and the service provider identification code that match. Since a communication line is established without mutual connection, transmission can be performed with improved economic efficiency in the same manner as in the above-described claim 1.

According to the third aspect of the present invention, when the outgoing telephone number is inputted, the outgoing telephone number identifying means,
Identifying the input calling telephone number, the control means, when the calling telephone number does not include the service identification code and the business operator identification code, or when the calling telephone number includes the service identification code and the business operator identification code The service identification code and the carrier identification code included in the calling telephone number and the service identification code and the carrier identification code assigned to the wireless communication network to which the wireless communication means can connect. If not, the wireless communication means is connected to a home wireless communication network using a simplified portable telephone system home line.

That is, in this system, a user inputs a calling telephone number, and then the calling telephone number does not include the service identification code and the carrier identification code, or the service identification number included in the calling telephone number. If the service code and the business identification code assigned to the wireless communication network connectable to the wireless communication means do not match with the service identification code and the business identification code, the home wireless communication using the home-use line of the simplified cellular phone system is performed. As described above, the communication network is automatically connected.In other words, in the case of interconnection, the number of interconnections is minimized and the communication line is established so as to minimize the communication fee. In the same manner as in the first and second aspects, transmission can be performed with improved economic efficiency.

Transmits a call signal to the PHS communication network 18 via the PHS public line via the radio base station 27 (step S
6).

Further, the control unit 2 determines that the calling telephone number is PHS
When the phone number is not the system phone number, or the calling phone number is P
Even if the telephone number is of the HS system, when the carrier identification code included in the outgoing telephone number is not the same as the carrier identification code assigned to the mobile phone device 1,
By outputting the control signal, the PHS radio unit 5 and the PHS baseband processing unit 6 control the transmission and reception in the PHS home mode. As a result, the control unit 2 transmits the call signal to the home PH through the PHS home line.
The data is transmitted to the S parent device 28 (step S7).

As described above, control unit 2 identifies the calling telephone number, and transmits the calling signal to PDC communication network 16, PDC.
Which of the HS communication network 18 and the home PHS master unit 28 is to be transmitted is selected.

(D) When making a call to the simplified portable telephone 24 In this case, the calling telephone number is a PHS telephone number (the service identification code is "050") assigned to the simplified portable telephone 24. But the simplified mobile phone device 2
No. 4 is assigned to the operator identification code (“G
H ") and the carrier identification code (" EF ") of the telephone number assigned to the mobile phone device 1 that is the originator, the mobile phone device 1 operates in the same manner as described in (b) above. Home PHS main unit 2 via PHS home line
8, a call signal is transmitted. That is, the portable telephone device 1 connects the public network 20 and the PHS communication network 19 to each other, thereby forming the public network 20 and the PHS communication network 19.
As a result, a communication line is established with the simplified portable telephone device 24.

(E) When making a call to the ordinary telephone device 25 At this time, since the outgoing telephone number is neither a PDC telephone number nor a PHS telephone number, the portable telephone device 1 is described in (b) above. In the same manner as described above, the calling signal is transmitted to the home PHS base unit 28 via the PHS home line. In other words, the mobile telephone device 1 establishes a communication line with the general telephone device 25 only by the public network 20 without the public network 20 being interconnected with another communication network.
