Abstract

PURPOSE:To enable correspondence without lowering service by referring to a storage part at the time of transferring a call control signal and deleting user/user information from the call control signal when a transfer destination switchboard is a switchboard not providing information transfer service. CONSTITUTION:An user/user information control part 5 refers to a call corresponding transmission signal buffer 13 and judges whether or not the user/user information is included in call control information (IAM signal.) When it is included, the station number of the transfer destination switchboard set at the label of the IAM signal is extracted, the station number corresponding user/user information control data of the storage part 4 are referred to and whether or not the transfer destination switchboard allows providing the user/ user information is judged. When it allows that, the IAM signal of the buffer 13 is transmitted as it is. When the transfer switchboard 3 does not allow providing the user/user information, the user/user information of the buffer 13 is deleted. Thus, user/user information transfer service is enabled without forcing any change to the switchboard.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a user information transfer control device. In recent years, the exchanges that make up the switching network are
With the diversification of user needs and the like, the functionality is advanced and it has a function of providing various services associated with communication. As one of them, there is a user-user information transfer service. When the user-user information is input from a terminal by a predetermined procedure, the user-user information is switched to a call signal (IAM signal) or a disconnection in an exchange that accommodates the terminal. This is a service that is added to a call control signal such as a signal (REL signal) and is sequentially transferred through the relay exchange if there is a relay exchange, and is sent to the terminal of the communication partner, generally to the terminal of the communication partner. Used to display a message.

In order to provide this service, it is necessary that all the exchanges constituting the exchange network have a function for providing the service, but recently, various exchange networks of different providers are provided. Since a large-scale switching network has been constructed by connecting to each other, it has become necessary to take measures in a switching system having a function of providing a user-user information transfer service.

[0003]

2. Description of the Related Art Conventionally, a user-user information transfer service is provided on the premise that the switching network as a whole, that is, all the exchanges constituting the switching network have a function of providing the service. Exchanges that do not have the function to do so have not been considered, and therefore no measures have been taken.

[0004]

By the way, recently, with the liberalization of communication business, various switching networks from different providers are connected in a complex manner to form a large-scale switching network. It is in. Therefore, it is conceivable that the switching network that does not provide the user-user information transfer service is connected to the switching network that does not provide the user.

However, conventionally, in order to provide a user-user information transfer service, it is premised that all the exchanges constituting the exchange network have a function of providing the service, and thus the above-mentioned method is used. When connecting,
It is necessary to add a function for processing user user information to a switching system of a switching network that does not provide the service, but in general, a change is made to the switching networks of other providers in order to provide services in the own switching network. Can't be forced. Therefore,
When making a connection as described above, there is no choice but to abandon the user information transfer service.

The present invention has been made in view of the above circumstances, and an object of the present invention is to connect a switching network which does not allow the user information transfer service to a switching network which allows the user information transfer service. A user-user information transfer service can be provided without forcing any change to the exchanges of the exchange network that do not allow the service.

[0007]

In order to solve the above-mentioned problems, a user-user information transfer control device whose principle configuration is shown in FIG. 1 is provided.

The user / user information transfer control device has a function of providing a service for transferring the user / user information input from the terminal 1 and added to the call control signal.
The present invention is applied to the exchange 2 and the first exchange 2 in the exchange network configured by mixing the second exchange 3 having no function.

This user-user information transfer control device is a user-user information control in which permission or denial of service provision is set corresponding to each of the numbers of all the exchanges 2 and 3 constituting the exchange network. When the transfer destination exchange is the exchange 3 that does not permit the provision of the service, the storage unit 4 in which data is stored in advance and the storage unit 4 is referred to when the call control signal is transferred. A user user information control unit 5 for deleting information is provided.

In addition to the above configuration, when the user user information control section 5 deletes the user user information, the charging processing station 6 is notified to stop charging processing for the service provision. The notification unit 7 and the user / user information deletion notification unit 8 for notifying the terminal 1 that has input the user / user information of the deletion can be provided and configured.

The transfer destination exchange is adjacent to each other in a connection route (transfer route) from an originating exchange accommodating a terminal which inputs user user information to a terminating exchange accommodating a terminal of a communication partner. Of the two exchanges, the exchange that receives the call control signal is referred to, and the exchange that transmits the call control signal is called the transfer source exchange.

[0012]

According to the present invention, with respect to all the exchanges forming the exchange network, whether or not the exchange permits the user / user information transfer service is held in advance as user / user information transfer control data, and the transfer destination exchange can If the exchange does not allow the service, the user information is deleted from the call control signal and transferred.

Therefore, among the exchanges forming the exchange network, the exchanges that do not allow the service do not need to be involved in the user-user information transfer service at all and do not provide the service to the exchange network that provides the user-user information transfer service. When connecting the switching network, it is possible to provide the user-user information transfer service without forcing any change to the switching system of the switching network that does not allow the service.

Here, if the user user information is added to the call control signal, the user user information transfer service may be charged separately from the charge for normal communication. In this case, if there is an exchange that does not allow the service in the call control signal transfer path and the user user information is deleted from the call control signal by the user user information transfer control device, the user user information does not reach the communication partner. However, there arises a problem that only charging is performed. In this case, a charging stop notification unit is provided to notify the charging processing station (usually the originating exchange, but may be another exchange or an exchange dedicated to charging) to stop the charging. It is good to

Similarly, when there is an exchange that does not allow the service in the transfer path of the call control signal and the user user information is deleted from the call control signal by the user user information transfer control device, the user user will be the communication partner. Although information will not be delivered, inconvenience may occur because the user-user information sender cannot recognize that the user-user information has not reached the communication partner. In this case, by providing the user user information deletion notification unit,
It is advisable to notify the terminal that transmitted the user information to that effect.

[0016]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a diagram showing a switching network according to an embodiment of the present invention. In the figure, 11 (11a to 11c) is an exchange of a network that provides a user-user information transfer service, and an exchange 12 is an exchange of a network that does not provide the service. Each exchange 1
1 and 12 are call signals (IAM signals) and disconnect signals (REL)
CCITT-N, in which call control signals such as
o. It is connected by the relay line of 7 common line signal system.

FIG. 3 is a diagram showing a schematic configuration of an exchange having a function of providing the user information transfer service shown in FIG. The exchange 11 includes a call-corresponding transmission signal buffer 13 that temporarily stores and holds call control signals from other exchanges and terminals, and a signal transmission unit 14 that transmits call control signals and other signals. A user user information transfer control device 15 according to the present invention is provided.

In the figure, 16 is a terminal capable of being provided with the user / user information transfer service accommodated in the exchange 11, and 17 is provided with the user / user information transfer service accommodated in another exchange. It is a terminal that cannot be used.

As an example of the call control signal transmitted / received between the exchanges 11, the structure of the calling signal (IAM signal) is shown in FIG.
It shows in (a). The IAM signal is a label (a station number of a transfer source exchange and a transfer destination exchange of the call control signal), a header, and calling / receiving number information (a number of a calling terminal including a number of a calling exchange that accommodates the calling terminal and a call receiving the receiving terminal). It is a signal composed of the number of the receiving terminal including the number of the exchange), the user information of the user, and other additional information.

The user / user information transfer control device 15 of the exchange 11 has the storage unit 4, the user / user information control unit 5, the charging stop notification unit 7, and the user / user information deletion notification unit as already described with reference to FIG. Eight.

More specifically, the station number-corresponding user-user information control data stored in the storage unit 4 is, as shown in FIG. 4 (b), all the exchanges 11 and 12 constituting this exchange network. It is data in which whether the exchanges 11 and 12 allow or disallow the user information transfer service is set corresponding to each of the station numbers.

The processing by the exchange 11 including the processing of the user information transfer controller 15 will be described with reference to the flowchart shown in FIG. First, a call control signal such as an IAM signal as shown in FIG. 4A is set in the call corresponding transmission signal buffer 13 of the exchange 11.

When the call control information (hereinafter, IAM signal) is set in the call-corresponding transmission signal buffer 13, an IAM signal transmission request occurs (step "abbreviated as ST" 1) 1 and the user-user information transfer control device 15 is activated. To be done.

The user / user information control unit 5 of the user / user information transfer control device 15 includes a call-corresponding transmission signal buffer 13
(ST2), it is determined whether or not the IAM signal includes user information (ST3). If the user information is included, the station number of the transfer destination exchange (next exchange) set in the label of the IAM signal is extracted (ST
4) Referring to the station number-corresponding user / user information control data in the storage unit 4 (ST5), it is determined whether or not the transfer destination exchange of the call control signal permits the provision of the user / user information (ST6).

When the exchange to which the call control signal is transferred permits the user to provide user information, the signal transmission unit 14
Control to the IAM of the call-corresponding transmission signal buffer 13
The signal is transmitted as it is (ST7). In ST3,
When the IAM signal does not include the user information, the control is transferred to the signal transmitting unit 14 and the call-corresponding transmission signal buffer 1
The IAM signal of No. 3 is transmitted as it is (ST7).

In ST6, if the transfer destination exchange does not permit the user user information to be provided, the user user information in the call corresponding transmission signal buffer 13 is deleted (ST).
8).

Then, control is transferred to the charging suspension notifying unit 7 or the user / user information deletion notifying unit 8 so that the own station (own exchange)
Determines whether it is the originating station (originating exchange) (ST
9). When the own station is the originating station, the originating terminal is notified that the user user information has been deleted (ST10), and the billing processing station (usually the originating exchange is set to stop the billing process for the user user information transfer service). In this case, the charging processing unit in the own exchange) is notified to stop the charging processing (ST11), and control is transferred to the signal transmission unit 14 to delete the IAM signal from which the user information is deleted. Is transmitted (ST7). The calling terminal notified in ST10 can make the caller recognize, for example, by displaying on the display of the terminal that the user information has not been transferred.

In ST9, if the own station is not the originating station, the originating exchange is notified that the user user information has been deleted (ST12), and control is transferred to the signal transmitting section 14 to delete the user user information. The transmitted IAM signal is transmitted (ST7). It should be noted that the notification that the user information has been deleted in ST12 is sent to the originating exchange through the transit exchange, if there is a transit exchange, and the originating exchange performs the same processing as ST10 and ST11.

In the above embodiment, the IAM signal (call origination signal) has been described as an example, but the same applies to other call control signals such as REL signal (disconnection signal) to which user user information is added.

According to the above-mentioned embodiment, when the exchange path which does not allow the user / user information transfer service is included in the connection path between the originating and terminating terminals, the service in the preceding position of the exchange which does not allow the user / user information transfer service is allowed. In the exchange, the user information is deleted, so that it does not impose a burden on the exchange that does not allow the service, and helps alleviate the congestion of the exchange.

Further, when the user user information is deleted, the charging for the user user information transfer service is stopped and the terminal which has transmitted the user user information is notified to that effect. There is no problem of being charged for being unable to receive the provision, or of not being able to recognize the fact that the user user information sender cannot recognize it.

In the above embodiment, the call control signal stored and held in the call-corresponding transmission signal buffer 13 has its label already set with its own exchange number as the transfer source exchange and the next exchange number as the transfer destination exchange. Although the description is given on the assumption that the data is stored and held after being processed, when selecting a transfer destination exchange (outgoing route), the user user information control data of the user user information transfer control device 15 is referred to and selected. It is preferable to preferentially select an exchange that permits the user-user information transfer service from the possible destination exchanges.

This will be explained with reference to FIG. 2. For example, when the terminal accommodated in the exchange 11a is the calling terminal and the terminal accommodated in the exchange 11c is the receiving terminal,
As a connection route (route) between the exchange 11a and the exchange 11c, there are two routes, a route passing through the exchange 11b and a route passing through the exchange 12. In this case, the exchange 11b should be preferentially selected. For example, it is possible to increase the probability that the caller / receiver can be provided with the user / user information transfer service.

[0034]

As described above in detail, by applying the user-user information transfer control device according to the present invention to the switch of the switching network which provides the user-user information transfer service,
It is possible to provide the user-user information transfer service without forcing any change to the exchange of the exchange network that does not allow the service.

Therefore, it becomes possible to deal with the complexization and large scale of the switching network without deteriorating the serviceability.
