[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a wireless communication system that allows communication by selecting the type of connection, whether a contention connection or a duplex connection, when a call is made from a wireless terminal. It is related to.

[Prior Art] This type of conventional wireless communication system is not equipped with a selection means for selecting a connection type, and connections are made according to connection types fixed to the system. That is,
If the originating and terminating wireless terminals are in the same wireless area, a drop-down connection is made to perform communication, and if the originating and terminating wireless terminals are in different wireless areas, a duplex connection is used. This allows communication to take place.

[Problems to be Solved by the Invention] In the conventional wireless communication system described above, connections are made according to connection types fixed to the system. However, there was the troublesome problem that facsimile communication, which is a service function unique to duplex connections, could not be performed, and when making a call, the user had to operate a breath talk button to make a call.

[Means for Solving the Problems] In order to solve such problems, the wireless communication system of the present invention includes a registration means for registering connection type data as subscriber data of a wireless terminal, and a registration means for registering connection type data as subscriber data of a calling party's wireless terminal. connection type selection means that selects registered connection type data of the called party when the callee makes a call to the wireless terminal of the called party, and performs an exchange connection based on this data.

[Operation] When the calling party's wireless terminal makes a call to the called party's wireless terminal, an exchange connection is performed based on the registered connection type data of the called party, and as a result, the calling party's wireless terminal and the called party's wireless terminal are connected. A call can be made with the caller's wireless terminal without having to operate a breathtalk button.

[Example] Next, the present invention will be explained with reference to the drawings.

The figure is a block diagram showing an embodiment of the wireless communication system of the present invention. In the figure, 1 to 4 are wireless terminals, 5 is a wireless communication channel group, 5a to 5f are wireless communication channels, 6 is a wireless base station, 7 is a voice relay line group, 7a to 7f are voice relay lines, and 8 is a switchboard. , 9 is a return trunk for simplex connection, and 1.0 is a subscriber database section.

When a certain wireless terminal among the wireless terminals 1 to 4 makes a call to another wireless terminal among the wireless terminals 1 to 4, the wireless terminal is connected to the wireless base station 6 via the wireless communication channel group 5. . The wireless base station 6 is connected to an exchange 8 via a voice relay line group 7, and transmits voice signals from the exchange to other wireless terminals among the wireless terminals 1 to 4 via a wireless communication channel group 5. Relay to terminal. Further, the return trunk 9 for simplex connection is housed in the exchange 8, and is used to return the voice signal when a simplex connection is established. Further, in the subscriber database unit 10, subscriber data of each of the wireless terminals 1 to 4 is registered by a registration means, that is, connection type data indicating whether it is a simplex connection or a duplex connection in this case. In the example, subscriber data is registered such that the wireless terminal 2 has a simplex connection and the wireless terminal 4 has a duplex connection.

First, a case in which the wireless terminal 1 calls the wireless terminal 2 and makes a conversation will be specifically described. When the wireless terminal 1 makes a dial call to the wireless terminal 2, the exchange 8 retrieves the subscriber data of the called party, the wireless terminal 2, from the subscriber database unit 10 based on the dial number included in the call information. Upon searching and recognizing that this is data indicating a simplex connection, the wireless terminal 2 sends an incoming signal to the wireless terminal 2 to receive the incoming call. When the wireless terminal 2 responds to this incoming call, the exchange 8 selects a simplex connection based on the recognized data.

That is, the exchange 8 connects the voice trunk lines 7a and 7b to the simplex connection trunk 9, and also connects the non-call channel 5.
Set a and 5b.

In this case, the communication between the two parties is by breath talk method, but there is no need to operate the breath talk button. That is, the audio signal of the wireless terminal 1 is automatically routed from the non-call channel 5a (indicated by a solid line) to the audio relay line 7a to
The voice signal from the wireless terminal 2 is relayed to the wireless terminal 2 and listened to in the order of the return trunk 9 → the audio relay line 7b → the wireless communication channel 5b (indicated by the solid line), and the audio signal of the wireless terminal 2 is similarly transmitted to the wireless communication channel 5a (indicated by the broken line). ) - voice trunk line 7a → return trunk 9 → voice trunk line 7b →
The radio communication channel 5b (indicated by a broken line) is relayed to the radio terminal 1 and listened to in this order. In this way, a telephone conversation between the wireless terminal 1 and the wireless terminal 2 is performed.

Next, a case will be described in which the wireless terminal 3 makes a call to the wireless terminal 4 for conversation. When the wireless terminal 3 makes a dial call to the wireless terminal 4, the exchange 8 transmits the subscriber data of the called party, the wireless terminal 4, based on the dial number included in the call information, in the same manner as described above. It searches the subscriber database unit 10 and recognizes that this is data indicating a duplex connection, and sends an incoming signal to the wireless terminal 4 to receive the incoming call. When the wireless terminal 4 responds to this incoming call, the exchange 8 selects duplex connection based on the recognized data. That is, the exchange 8 connects the voice trunk line 7c and the voice trunk line 7f, and also the voice trunk line 7d and the voice trunk line 7e.
At the same time, wireless communication channels 5c, 5d, 5e, and 5f, which are relayed by voice relay lines 7c, 7d, 7e, and 7f, are set to 6, respectively.

Therefore, the audio signal of the wireless terminal 3 at this time is relayed to the wireless terminal 4 in the order of the non-call channel 5c, the audio relay line 7c, the audio relay line 7f, and the wireless communication channel 5f.

In addition, the audio signal of the wireless terminal 4 is transmitted to the wireless communication channel 5.
It is relayed to the wireless terminal 3 in the order of e→audio relay line 7e→audio relay line 7d→wireless communication channel 5d. In this way, a conversation between the wireless terminal 3 and the wireless terminal 4 is performed.

In this way, the selection of the connection type, simplex connection or duplex □ connection, is determined based on the subscriber data of the wireless terminal 2.4 that is the called party, and It does not depend on the subscriber data of terminals 1 and 3. If duplex connection data is registered in the subscriber data of wireless terminal 2.4, which is the called party, not only communication with this wireless terminal 2.4 but also service functions specific to duplex connection will be performed. facsimile communication can be performed.

[Effects of the Invention] As explained above, in the wireless communication system of the present invention, when the calling party's wireless terminal makes a call to the called party's wireless terminal,
Since the configuration is configured to perform an exchange connection based on the registered callee's connection type data, a call can be made between the calling party's wireless terminal and the called party's wireless terminal without operating a button for breath talk. This has the effect of allowing you to do this. Furthermore, if the called party's connection type data is registered as duplex connection and a call is sent to the called party's wireless terminal, facsimile communication, which is a service function unique to duplex connection, can be performed with this wireless terminal.
