Description

Description: TECHNICAL FIELD The present invention relates to a switching control system, and more specifically, to a control system for outgoing and incoming calls in an automatic exchange.

(Prior Art) For example, Ishikawa et al., "Concept of advanced telephone network system", IEICE Exchange Study Group material SE84-12, describes a database for centrally managing subscriber data related to new services as a network service control station (NSP). As a new service call, the advanced telephone network system which provides various services by referring to the new service call using a common line prior to call connection is being studied.

According to this method, when a subscriber accommodated in a subscriber line switch uses a new service, the switch is accessed by a so-called new service number assigned to the service. If necessary, the number of the connection destination, that is, the identification number of the subscriber device or the subscriber device group called a general telephone number is dialed. When the subscriber exchange identifies the new service call by the new service number, it activates a connection control station having a function necessary for call connection of the new service, and sends a general telephone number to this.

At the connection control station, the identification number of the calling subscriber device, that is, the accommodation position of the calling subscriber device in the subscriber line exchange,
Information about the originating area that can be identified by the incoming line is obtained, and these are sent to the network service control station via the common line.

The network service control station identifies the service type based on these pieces of information, and refers to the corresponding subscriber data to judge whether the service can be provided. Further, the connection destination is selected, the connection format is determined, and these are transmitted to the connection control station via the common line.

Therefore, the connection control station sets the call train according to the information received from the network service control station, and sends the connection information to the subscriber line switching station on the called side as necessary. The called station calls the called party according to this, and the called party responds to enter the call according to the new service.

The call control is performed by the connection control station, and when the end of the call is detected, the connection control station transfers the data of the response time and the call disconnection time to the network service control station. The network service control station calculates the charging degree from the received time information and the provided service, and performs the counting.

(Problems to be Solved by the Invention) With such a conventional exchange control method, when a caller makes a call from his or her own terminal device, a new service can be provided appropriately. However, if the caller requests a new service call from another terminal that is not his or her own terminal, there is no guarantee that the same new service is registered for that terminal, so that the new service cannot always be received. That is, the subscriber data registered in the network service control station is unique to the subscriber's terminal device, not to the subscriber itself. Therefore, in general, subscribers are only guaranteed to receive the appropriate new services from their terminals.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned drawbacks of the prior art and provide a switching control system that enables a subscriber to be provided with an appropriate new service from any terminal.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention is directed to a subscriber or a group of subscribers assigned to a subscriber or a group of subscribers when making a call from a subscriber unit to an automatic exchange. To the exchange, which manages the correspondence between the number assigned to the subscriber device and the subscriber identification number, and the call path setting is the number assigned to the subscriber device. The calling subscriber identification and billing management is characterized by processing by the subscriber identification number.

(Operation) According to the present invention, the host station of the exchange in which the subscriber device is accommodated manages the subscriber by the subscriber identification number, not by the number assigned to the subscriber device, thereby Performs call processing associated with a subscriber independent of the subscriber device used.

(Embodiment) Next, an embodiment of the exchange control method according to the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, in an embodiment in which the present invention is applied to a new service of an advanced telephone network, two subscriber line exchanges (LS) are used.
10 and 12 are connected by trunk lines 16 and 18 via a connection control station. The subscriber line exchange 10 has a plurality of terminals.
It houses 20 and 22. In this example, the terminal 20
For example, it may be a normal telephone having a push-button dial function and has a number given to the device, that is, a number ABCD called a general telephone number. Similarly, the terminal 22 has a general telephone number EFGH. Each of these terminals 20 and 22 may be a group of subscriber devices, for example terminal devices housed in a PBX exchange. Of course, since these general telephone numbers correspond one-to-one to the accommodation positions in the network of the subscriber line exchange 10 or 12, they may be interpreted as a concept including the accommodation positions. In this specification, the term “number” is to be interpreted in a broad sense that includes not only numbers but also characters such as symbols and alphabets.

The trunk side of the subscriber line exchange 10 accommodates an outgoing trunk (OGT) 24 to which a trunk line 16 is connected. Of course, these circuit devices are usually installed by an algebra corresponding to the traffic, but only those necessary for understanding the present invention are shown in order to avoid complication of the drawing.

The trunk line 16 is connected to an incoming trunk (ICT) 26 of the connection control station, and the connection control station 14 has a switch network 14 to which functions necessary for call connection of a new service are added. An outgoing trunk 28 to which a trunk line 18 is connected to the network 14,
It contains circuit devices necessary for new service functions, such as push-button dial (PB) signal receiving device (PBREC) 30 and voice response device (ARE) 32. The network 14 is controlled by a central control unit (CC) 34, which is connected by a common line signaling unit (CSE) 36 via a signal relay station STP to a network service control station (NSP) 38.

The network service control station 38 is a kind of database provided with logical functions necessary for providing a new service, such as managing data of a subscriber who provides a new service, analyzing the service and controlling the data. Although details of these data will be described later, they are stored in the file memory (FM) 40 and processed by the central controller (CC) 42.
The central control unit (CC) 42 is connected to a connection control station via a common line signaling device (CSE) 44 via a signal relay station STP.

The trunk line 18 from the connection control station is connected to an incoming trunk 46 accommodated on the trunk side of the subscriber line exchange 12.
The subscriber line exchange 12 accommodates a plurality of terminals 48 and 50. In this example, the terminal 48 is, for example, an ordinary telephone and its general telephone number is ABGH. Terminal 50 as well
Has a general telephone number EFCD.

In the new service system of this embodiment, a subscriber who wants to receive a new service is provided with a number for identifying himself, that is, a subscriber identification number (UON). For example, as shown in FIG. 1, a subscriber 70 is assigned a subscriber identification number 1234. Of course, when a new service of the same type is provided to a group of subscribers, one subscriber identification number is given to the subscriber group. For example, in FIG. 1, a subscriber identification number 5678 is assigned to a group of subscribers 72. That is, a subscriber identification number is an identification number assigned to a group of subscribers of at least one subscriber who is handled by the switching system to make and receive calls of a particular type.

With these subscriber identification numbers, any of the new classes of services So to Sn for which the subscriber is offered are assigned to the subscriber. Subscriber data including the subscriber identification number and the service class are registered in the data file 40 of the network service control station 38 as a subscriber data management table 66. In this example, the subscriber with subscriber identification number 1234
70 has new service class S0 and subscriber identification number 5678
A new service class Sn is registered for the subscriber 72 having

In the control system of the subscriber line exchanges 10 and 12, the management table 60,
Use 62 or 64 to manage correspondence between general telephone numbers and subscriber identification numbers. This will be described in detail later.

As will be seen later, the subscriber line exchange 10 and
The management tables 60, 62 and 64 of 12 store the subscriber identification number entered by the subscriber when the subscriber originates using any terminal in association with the general telephone number of the originating terminal. In the present embodiment, when an incoming call is made to the subscriber, the subscriber identification number thus accumulated is used to retrieve a general telephone number corresponding to the subscriber identification number.

The operation will be described. The outline of the operation sequence described below is shown in the connection sequence diagram of FIG. For example, when the subscriber 70 having the subscriber identification number 1234 uses the new service, the terminal having the general telephone number ABCD is used in this embodiment.
A terminal that has a general telephone number EFGH even if you call from 20
Even if you call from 22, you can receive the same service.

For example, when making a call from the terminal 20, the subscriber 70 has his / her own subscriber identification number 1234, a new service number assigned corresponding to the new service, and a destination subscriber who connects using this new service, such as a subscriber. Dial 74 General Telephone Number, EFCD. At this time, it is assumed that the new service requested by the subscriber 70 is the registered service class S0.

From these numbers, the subscriber line exchange 10 identifies that the call is an outgoing call requesting a new service, and activates the connection control station via the outgoing trunk 24, the trunk line 16 and the incoming trunk 26. The subscriber line exchange 10 identifies from the accommodating position of the terminal 20 that the general telephone number of the calling terminal 20 is ABCE, and from the terminal 20 having the general telephone number ABCD to the subscriber 70 having the subscriber identification number 1234. Know that you are calling. Correspondence between the calling terminal 20 and the subscriber 70 at that time is time t = m.
It is written in the management table 60 in and is managed using this. For example, when the subscriber 70 makes a new service call from another terminal 22 at another time t = m + 1, the correspondence between the general telephone number EFGH and the subscriber identification number 1234 is managed as shown in the management table 62. It

When the calling subscriber's line exchange 10 activates the connection control station, the calling subscriber information such as the new service number, the general telephone number EFCD of the partner subscriber 74, and the subscriber identification number 1234 of the calling subscriber 70 is relayed to the trunk line 16 To the connection control station. The central control unit 34 of the connection control station obtains the information indicating the originating area from the information received from the exchange 10 and sends them from the common line signaling unit 36 to the network service control station 38.

In the network service control station 38, the central control unit 34 accesses the file 40 and refers to the subscriber data based on the information transferred from the connection control station to judge whether the service can be provided. In this example, referring to the management table 66, it can be seen that the new service class S0 is registered with the subscriber 70 having the subscriber identification number 1234 for the current call. Therefore, in this example, it is determined that the new service S0 may be provided. In other words, the judgment at this time is the subscriber identification number 1234.
Whether or not it is possible to provide the service of the new service class S0 to the subscriber 70 who has the
The feature is that 20 general telephone numbers ABCD do not make this judgment. Also, the connection destination is selected based on the general telephone number EFCD of the connection destination 74 to determine the connection format. The connection destination information and connection method information can be obtained from the common line signaling device.
It is sent from 44 to the connection control station.

The central control unit 34 of the connection control station sets the call train according to the received connection permission, connection destination information and connection format information. This activates the subscriber line exchange 12 through the trunk line 18. This is followed by the incoming subscriber 74 from the connection control station to the exchange 12 through the trunk line 18.
The general telephone number EFCD is sent.

In the subscriber line exchange 12, the general telephone number EFCD,
The connection is set to the terminal 50, and the calling operation of the terminal 50 is started.
When the called subscriber 74 answers, the call by the service class S0 can be performed.

When the connection between the originating and terminating subscribers is set up, the connection control station monitors the call. Upon detecting the end of the call, the central control unit 34 of the connection control station transfers the charging information such as the response time and the call disconnection time to the network service control station 38. The network service control station 38 calculates the accounting degree from the received time information and the provided service, and adds the accounting degree.

(Effects of the Invention) According to the present invention, as described above, the subscribers are managed not by the general telephone number of the subscriber device but by the subscriber identification number in the station higher than the exchange in which the subscriber device is accommodated. . Therefore, the subscriber appropriately performs call processing such as new services permitted to the subscriber, regardless of the originating subscriber device.
