Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for exchanging a communication right required for connecting to a public line via a public base station in a communication system having a plurality of radio communication terminals.

[0002]

2. Description of the Related Art In the case of using a wireless communication terminal to receive a service for connecting to a public line through a public base station, a one-to-one wireless communication terminal from a communication carrier is used to authenticate each wireless communication terminal. Two communication rights are given. This communication right is uniquely given to the wireless communication terminal by the telecommunications carrier, and it is impossible for the owner of the wireless communication terminal to reset or re-register this communication right personally.

As described above, conventionally, since only one wireless communication terminal can have one communication right that cannot be reset or re-registered, not only voice but also data transmission / reception can be performed using the wireless communication terminal. If you want to do so, it will take time and effort to reconnect the wireless communication terminal with the registered communication right to the data communication device. The problem arises that communication rights must be earned more than necessary, such as by separately using them for communication and data communication.

In order to solve this problem, a method of sharing one communication right among a plurality of terminals can be considered. But,
When one communication right is shared by a plurality of terminals, it becomes necessary to exchange the communication right between the wireless communication terminals. As a method of exchanging the communication right in this case, it is possible to attach a device such as an IC card having communication right information to a wireless communication terminal and share this device with a plurality of wireless terminals.

[0005]

As described above, conventionally, an apparatus such as an IC card has been used to share one communication right among a plurality of terminals. However, when a device such as an IC card is repeatedly attached and detached for the purpose of giving and receiving a communication right, the contact portion of the device is deteriorated, which may hinder the transmission and reception of the communication right. There is also a problem that mounting a device such as an IC card on a wireless communication terminal impairs portability of the terminal.

[0006] Therefore, an object of the present invention is to solve the above-mentioned problem by realizing communication between wireless communication terminals by communication between the wireless communication terminals.

[0007]

To achieve the above object, the present invention provides a wireless communication terminal group consisting of a plurality of wireless communication terminals that can communicate with each other without using a public line.
A communication right for granting to one of the wireless communication terminals the communication right required when the wireless communication terminals in the wireless communication terminal group assigned to the wireless communication terminal group communicate through a public line. In the communication system having a granting means, the communication right granting means is a communication right transmitting means for transmitting the communication right to one of the wireless communication terminals, and a communication right for receiving the communication right sent back from the wireless communication terminal. And a right receiving means.

Here, the wireless communication terminal has a communication right storage management means for storing and managing the communication right, and the communication right storage management means transfers the communication right from the communication right transmitting means to the communication right receiving means. When the communication right is transmitted, the stored communication right is deleted, and when the communication right transmitting means receives the communication right from the communication right transmitting means, the communication right is stored and set.

The communication right storage management means determines the communication right is stored in the wireless communication terminal, and the communication right storage determination means determines the communication right according to the determination result of the communication right storage determination means. And a communication right display means for displaying that the is stored.

Further, the communication right granting means suspends the communication before and after the communication via the public line or at an arbitrary point in the middle of the communication, and at the same time the communication terminal 1
First, the communication right is transmitted, and when the transfer of the communication right is completed, the communication with the communication terminal which has been communicating via the public line is restarted.

When it is confirmed by the inter-terminal communication means that the transmission to other wireless communication terminals in the group is completed, the communication right information control unit 141 erases the communication right information in the communication right storage buffer 142. Further, when the communication right information is sent to the communication right information control unit 141 through the communication right receiving unit 12, the communication right information control unit 141 stores the communication right information sent in the communication right storage buffer 142. The transmission control unit 131 is notified that the communication right information storage is completed. The information on the completion of saving the communication right passes through the communication right transmitting unit 12 and is notified from the inter-terminal communication control unit 11 to the wireless communication terminal on the communication right transmitting side by using the inter-terminal communication means.

FIG. 6 is an operation flowchart of the communication right handing process of the wireless communication terminal on the communication right transmitting side, and FIG. 7 is an operation flowchart of the communication right handing process of the wireless communication terminal on the communication right receiving side. The flow of the communication right transfer processing operation will be described again with reference to FIGS. 6 and 7.

In the wireless communication terminal on the communication right transmitting side, the frame including the communication right is transmitted from the transmission / reception unit 111 in the inter-terminal communication control unit 11 (step 101 in FIG. 6).

The inter-terminal communication control unit 11 receives the frame sent from the wireless communication terminal on the communication right receiving side (step 201 in FIG. 7). This frame is first the terminal recognition unit 1
It is determined in 13 whether or not the wireless communication terminals are from the same group (step 202 in FIG. 7), and the frame recognition unit 114 further determines whether or not the communication right information is included (step 203 in FIG. 7).

When it is determined that the wireless communication terminals of the same group include the communication right information, the inter-terminal communication control unit 11 outputs this frame to the communication right receiving unit 12, and the communication right receiving unit 12 outputs the frame. This is received (step 204 in FIG. 7) and sent to the communication right storage management unit 14. In the communication right storage management unit 14, the communication right information control unit 141 stores the communication right in the communication right buffer 142 (step 20 in FIG. 7).

When the storage of the communication right is completed (step 206 in FIG. 7), the information to that effect is sent from the communication right information control unit 141 to the transmission control unit 131 of the communication right transmission unit 13, and further, the inter-terminal communication control unit. The frame forming unit 112 of 11 forms a frame, and the frame is transmitted from the transmitting / receiving unit 11 to the wireless communication terminal on the communication right transmitting side (step 207 in FIG. 7). When the notification of the completion of saving the communication right is completed (step 208 in FIG. 7), the process ends (step 209 in FIG. 7).

The wireless communication terminal on the communication right transmitting side transmits a frame containing the communication right and then receives the frame at the transmitting / receiving section 111 (step 102 in FIG. 6).
In step 14, it is determined whether or not it is a communication right saving completion notification from the communication right receiving side wireless communication terminal (step 103 in FIG. 6). If it is a communication right saving completion notification, the communication right information control unit 141 stores in the communication right storage buffer 142. Communication right is deleted (step 104 in FIG. 6), and if the deletion is completed (step 105 in FIG. 6)
The process ends (step 106 in FIG. 6). Step 10
If the frame received in 3 is a normal frame, a normal call is started (step 107 in FIG. 6).

The communication right can be transmitted and received by the functions of the respective parts described above. However, in the above cases, it is necessary to give and receive the communication right in advance at the time of starting the communication via the public line, and the communication right is transferred from one wireless communication terminal to the other wireless communication terminal during the communication via the public line. When moving to, there is a problem that it is not possible to determine which wireless communication terminal has the communication right. Next, another embodiment of the present invention for solving this point will be described.

When the communication right is stored in the communication right storage buffer 142, the communication right display unit 144 is driven. Make the display.

This embodiment is effective when the terminal wants to transfer the communication right during a call.

The operation when the terminal moves the communication right during a call will be described with reference to FIG.

It is assumed that the wireless communication terminal A is in communication with the wireless communication terminal B via the base station and the public line. In this communication state, the wireless communication terminal A interrupts the communication with the wireless communication terminal B and moves the communication right to the wireless communication terminal C by the inter-terminal communication means. When the communication right holding determination unit 143 determines that the communication right has been deleted from the communication right storage buffer 142 of the terminal A after the transfer of the communication right is completed, the wireless communication terminal A reoccurs to the wireless communication terminal B. A call is made and communication with the wireless communication terminal B via the base station and the public line is restarted.

FIG. 9 is an operation flowchart of the communication right transfer process of the wireless communication terminal A on the communication right transmitting side when the communication right is transferred during communication.

The flow of the communication right handing processing operation when the communication right is moved during communication will be described again with reference to FIGS. 7 and 9.

When the communication right transmitting side wireless communication terminal A needs to move the communication right during communication with the wireless communication terminal B through the base station and the public line, the communication with the wireless communication terminal B is performed. It is interrupted (step 302 in FIG. 9).

In the communication right transmission side wireless communication terminal A, the transmission section 111 in the terminal communication control section 11 transmits a frame including the communication right (step 304 in FIG. 9).

In the wireless communication terminal C on the communication right receiving side, the terminal communication control section 11 receives the transmitted frame (step 201 in FIG. 7). This frame is first the terminal recognition unit 1
It is determined at 13 whether or not the wireless communication terminals belong to the same group (step 202 in FIG. 7), and the frame recognition unit 114 further determines whether or not the communication right information is included (step 203 in FIG. 7).

If it is determined that the wireless communication terminals of the same group include the communication right information, the terminal communication control unit 11 outputs this frame to the communication right receiving unit 12,
The communication right receiving unit 12 receives this (step 2 in FIG. 7).
04), and sends it to the communication right storage management unit 14. In the communication right storage management unit 14, the communication right information control unit 141 sets the communication right buffer 1
The communication right is stored in 42 (step 205 in FIG. 7). If the frame does not come from a wireless communication terminal of the same group, or if the communication right information is not included, a normal call is started (step 210 in FIG. 7).

When the storage of the communication right is completed (step 206 in FIG. 7), the information to that effect is sent from the communication right information control unit 141 to the transmission control unit 131 of the communication right transmission unit 13 and further, the terminal communication control unit 11 of the terminal communication control unit 11. The frame is created by the frame creating unit 112 and sent from the transmitting / receiving unit 111 to the communication right transmitting side wireless communication terminal A (step 207 in FIG. 7). When the notification of the completion of saving the communication right is completed (step 208 in FIG. 7), the process ends (step 209 in FIG. 7).

In the wireless communication terminal A on the communication right transmitting side, after transmitting the frame including the communication right, the transmitting / receiving section 111 receives the frame (step 305 in FIG. 9), the frame recognizing section 114 performs wireless communication on the communication right receiving side. It is judged whether or not the communication right storage completion notification is issued from the terminal C (step 30 in FIG. 9).
6) If it is a communication right saving completion notification, the communication right information control unit 141 deletes the communication right in the communication right buffer 142 (step 307 in FIG. 9), and if the deletion is completed (step 309 in FIG. 9), Then, in step 302, the call is re-established to the wireless communication terminal B, which is the partner terminal for which the communication is interrupted (step 310 in FIG. 9), and the communication with the wireless communication terminal B is restarted.

On the other hand, in the terminal C which has acquired the communication right, the communication right is stored in the communication right storage buffer 142 of the terminal C.
This is discriminated by the communication right holding discriminating means 143, and the communication right display section 144 of the terminal C displays that there is a communication right.

The display method of the communication right display section 144 is the exclusive L
Display means such as an ED may be provided and displayed on the display means, or may be displayed by a specific method on an LCD display device for operation display which the wireless communication terminal already has, or by another method. Is also good.

Since the movement of the communication right between the wireless communication terminals in the same group is immediately displayed in this way, the communication right can be moved between the wireless communication terminals in the same group for communication during a call. This makes it possible to switch between a plurality of terminals and perform optimal communication.

In the above description, it is described that the function for granting the communication right is in the wireless communication terminal which currently owns the communication right, but the communication right granting means is a specific one wireless communication terminal in the same group. May be given to the user, or a communication right granting means may be separately set. In any case, the communication right can be transferred by the processing basically the same as the above-mentioned processing.
