Abstract

PROBLEM TO BE SOLVED: To surely exchange UUI(user to user information) by executing the 'call setting' message of a newly started call by means of UUI without using a 'disconnection' or 'release end' message at the time of UUI transmission as response to the calling terminal of a call incoming terminal. SOLUTION: When a call incoming side terminal receives the call setting message with UUI from the calling terminal, the disconnecting message is transmitted to a network and the call is temporarily disconnected and restored. The terminal 1 transmits the call setting message with UUI including a return electronic message after recognizing the restoration of the call and, then, executes calling to the calling terminal. The call setting message which is started as new call control sequence after disconnection restoration is re-called later since the network reports an interruption reason to the terminal even when there is no channel to be newly used since another bus-connected terminal is under calling so as to cause interruption in result. Therefore, the call setting message is transmitted to the whole bus-connected terminals by a broadcasting system so that sure communication is enabled.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a user / user information (UUI) transfer system for reliably transmitting / receiving user / user information, and a UUI telemeter apparatus and a UUI system to which the system is applied
The present invention relates to a UI telemeter processing method.

[0002]

2. Description of the Related Art By including user / user information (UUI) in a call control message, information up to 128 octets can be transmitted and received at a low cost of 0.4 yen, which is uniform throughout the country.

[0003] A calling terminal sends a call setup message including a UUI to a called terminal of the other party. After receiving the UUI, the called terminal normally disconnects the call once, and transmits information as a UUI in the disconnection message or the like. By including it, response information and the like can be transmitted to the calling terminal.

[0004] In this case, it is possible to send the UUI included in the disconnection message to the calling terminal even if the receiving terminal enters a call state without disconnecting immediately and then performs a disconnecting process on the receiving terminal side. In order to enter the call state, a call charge of at least 10 yen is required.

[0005] If the UUI is transmitted and received without entering the talking state, information of up to 128 octets can be transmitted and received for 0.8 yen, so that the utility value is high.

Heretofore, the calling side has sent a call setup message including the UUI to the called terminal (called terminal), and the called terminal that has received the call returns a disconnection message including the UUI. A pair of cuts and B
UUI was sent and received without entering a call state using a channel. Moreover, this conventional method has the following two problems.

[0007] In some cases, the UUI cannot be delivered from the called terminal to the calling terminal.

In the ISDN, up to eight terminals can be connected to one subscriber line (bus connection or point / point connection).
If a multi-point connection) receives a call setup message including a UUI in this bus connection state, the UU
If another terminal connected to the bus transmits a paging message or response message to the network in response to the call setup message even if the disconnection message including the I is transmitted to the network, To prioritize the message of the terminal trying to establish a call over the terminal trying to disconnect,
The call processing of the terminal related to the call or response message is continued, and as a result, the disconnect message including the UUI is discarded in the network.

[0009] Therefore, U in the direction from the called terminal to the calling terminal.
The UI becomes undeliverable.

If a plurality of terminals connected to the bus all have a check function and strictly determine communicability / consistency based on a dial-in number, subaddress, transmission capability included in a call setup message, etc. Although it will not be undeliverable, this check function is left to the discretion of the terminal side, so in reality there may be cases where carelessly returns a "call" or "response" message depending on the terminal, As a result, the UUI will not reach the other party.

The terminal cannot know that the UUI has been discarded.

[0012] Even if the UUI (including the disconnect message) that the called terminal attempts to transmit to the calling terminal is discarded in the above-described situation, the fact that the UUI originated the calling terminal is generally not recognized by the called terminal. Is not informed.

[0013] Therefore, the inability to deliver cannot be recovered by retransmission.

FIG. 5 is a diagram for explaining a conventional example in which the terminal cannot know that the user / user information (UUI) has been discarded, so that the inability to recover cannot be recovered by retransmission.

A call setting message including the UUI of the calling terminal (call setting, uui in FIG. 5) is intended to transmit and receive the UUI to and from the terminal 1 of the called terminal. Even in the case where the terminal 1 and the terminal 2 connected to the bus are not provided with a function of determining whether or not the destination subaddress of the call setting message matches its own subaddress at the stage of confirming the communication possibility, the call It incorrectly determines that the setup message is intended to establish a call with itself, and sends a ringing message to the receiver and a call message expecting to establish a call to the network (ISDN).

Even if the terminal 1 issues a disconnection message including the UUI before the paging message of the terminal 2, if the network receives the paging message from the terminal 2 within a predetermined time, the network disconnects. The subsequent processing proceeds with respect to the intention of the terminal 2 that desires to establish a call.

Therefore, the call message of the terminal 2 arrives at the calling terminal, but the expected response from the terminal 1 is U.
Since the disconnection message having the UI (FIG. 5) is discarded by the network, it does not reach the calling terminal.

Further, the terminal 1 is not notified that the disconnection message having the UUI has been discarded.

As described above, the conventional method of transmitting and receiving a UUI by a call setup / disconnection message belonging to one call setup sequence has a drawback that lacks certainty.

[0020]

SUMMARY OF THE INVENTION One object of the present invention is to provide a user / user information transfer system capable of reliably transmitting / receiving user / user information.

Another object of the present invention is to apply a user / user information transfer system capable of reliably transmitting / receiving user / user information, thereby constructing a highly reliable meter reading system at a low communication fee. An object of the present invention is to provide a UUI telemeter device and a telemeter processing method of the UUI telemeter device.

[0022]

According to the present invention, in order to solve the above-mentioned problems, a called terminal transmits a UU to a calling terminal as a response.
When transmitting I, the UUI of the "call setup" message of the newly started call is performed without using the "disconnect" or "release complete" message.

That is, the call setting message from the calling terminal
The called terminal that has received the UI temporarily disconnects and releases the call by issuing a “disconnect” or “release complete” message at that time.

The disconnection / release completion message at this time does not include the UUI. Thereafter, the called terminal sends a call setup message for making a new call to the calling terminal, and returns a response with a UUI of the call setup message.

When the called terminal transmits the UUI to the other party in the disconnection message, the network automatically generates the call even if the called terminal does not specify the called number and called sub-address (hereinafter called called number) of the calling terminal. The call is delivered to the call terminal (of course, if the other terminal connected to the bus does not interfere), but as in the present invention, when the UUI is sent in the call setup message issued by the called terminal, a normal call setup message is sent. Similarly, a called number, which is the telephone number of the other party, is required.

In the present invention, the destination number and the like are designated by one of the following three methods.

1) The calling number included in the call setup message received by the called terminal from the calling terminal immediately before or in the past,
Use source subaddress. If the calling terminal refuses to display the calling number on the called terminal, the called terminal cannot use the calling number.

2) UU included in the same message as in the previous section
The information set in advance by the calling terminal or the like in I is used as a called number or the like.

3) Information determined between terminals in advance is used as a called number or the like.

The structure of the present invention is as follows. That is, in a service (user / user signal service 1) for transferring user / user information included in a call control message in a call setup / disconnection recovery phase of ISDN, user / user information included in a call setup message of a calling terminal is transmitted. After the receiving terminal that has received the call disconnects and recovers the call, it initiates a new call to the calling terminal, and responds to the calling terminal using the user information of the call setting message. It has a configuration as a user / user information transfer method characterized by transmission.

Alternatively, the called terminal uses the calling number and calling sub-address included in the call setting message received from the calling terminal in the past as the called number and called sub-address necessary for setting a new call. It has a configuration as a user / user information transfer method characterized by returning a response to the call terminal.

Alternatively, address information previously set on the calling terminal side in the user / user information of the call setting message received from the calling terminal in the past as the called number and called sub-address required for setting a new call. The called terminal returns a response to the calling terminal using the
It has a configuration as a user information transfer method.

[0037]

FIG. 1 is a principle configuration diagram for explaining the operation of the user / user information transfer system of the present invention.

In the present invention, the called terminal (terminal 1 in FIG. 1)
Receives a UUI call setup message from the calling terminal, sends a disconnect message to the network, and temporarily disconnects and restores the call.

After confirming the restoration of the call, the terminal 1 sends a call to the calling terminal by transmitting a call setup message with a UUI including a reply message or the like (FIG. 1).

As is apparent from the above description, when another terminal connected to the bus returns a call message or a response message to the network, the disconnection message with UUI issued by the called terminal is discarded by the network and does not reach the calling terminal. However, the call setup message started as a new call control sequence after restoration from the disconnection is interrupted as a result of the absence of a new channel available because another terminal connected to the bus is busy. Even if a call is made, the network informs the terminal of the reason for the interruption, so that it is possible to make a call again later.

Since the call setting message is transmitted to all terminals connected to the bus in a broadcast format, reliable communication is possible.

As described above, when the present invention is applied, the above two drawbacks can be overcome, communication can be reliably performed at low cost with a UUI, and the utility of the UUI can be enhanced.
