Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a switching system, and particularly to a system for assigning individual telephone numbers suitable for tracking the location of a calling party within a switching network.

[Conventional technology]

Conventionally, as a method for allocating telephone numbers to individuals in an exchange system, a method is known that takes into account only the numbering plan within one exchange, as described in, for example, Japanese Patent Application Laid-open No. 125268/1983.

[Problem that the invention seeks to solve]

In the above-mentioned conventional technology, in a switching network consisting of multiple exchanges,
No consideration was given to using individual telephone numbers to connect telephones connected to different exchanges.

An object of the present invention is to enable the assignment of multiple individual phone numbers to one telephone as in the above-mentioned prior art, and also to allow the assignment of one's own individual telephone number from a telephone connected to any exchange in the switching network. If you register your phone number, you will be able to receive future calls to that phone, and the caller will be able to tell you which phone the callee is connected to in the exchange network. The purpose is to enable a call by simply dialing the individual telephone number of the called party, without considering whether or not the caller is using the telephone number.

[Means for solving problems]

The purpose of the above is to provide a procedure for notifying the individual telephone number from the telephone to the exchange to which the own telephone is connected and the central exchange within the exchange network, and to transmit the individual telephone number within the exchange and the central exchange to the telephone unique number and the exchange. This is achieved by providing a memory for registering the correspondence with the number, and a procedure for specifying the telephone within the exchange network to which the call is to be received using the memory and the individual telephone charge amount dialed at the time of outgoing call. Note that in the above, the individual telephone number is unique within the exchange network, whereas the telephone unique number is unique within the exchange.

[Effect]

When the exchange receives the individual telephone number to be registered from the electric machine, it registers the correspondence between the telephone unique number and the individual telephone number in its memory, and transmits the correspondence to the central exchange. When the central exchange receives the correspondence between the telephone unique number and the individual telephone number from the exchange, the central exchange further adds the exchange number and registers it in the memory. As a result, when the exchange receives the called party's personal telephone number from the power generator, it exchanges it with the called party's personal telephone number based on the memory in its own exchange and establishes a connection between the calling and receiving telephones. If the number is not registered in the memory, the individual telephone number of the called party is sent to the central exchange.

The central exchange uses the above-mentioned correspondence table in the memory of its own exchange to find the exchange number and telephone number to which the call should be called, and returns them to the originating exchange.Based on that information, the originating and terminating exchanges establish a connection between the originating and terminating telephones. .

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows the structure of a correspondence table between individual telephone numbers and telephone numbers, which is provided on the memory in the exchange in order to implement the present invention. This is a configuration example assuming 3 digits. The correspondence table is the lower digit search table 1, which searches by the upper digit i when the individual telephone number is ijk. It consists of a middle digit search table 4 for searching by the middle digit j and a lower digit search table 5 for searching by the lower digit. Both the upper digit search table 1 and the middle digit search table 4 consist of a registration valid display 2 and a next digit search table pointer 3. The registration valid display is used to prevent individual telephone numbers such as system reservation numbers that cannot be used by general individuals from being registered when registering individual telephone numbers, or to prevent registration of individual telephone numbers that cannot be used by general individuals, such as system reservation numbers, or when the individual telephone number is registered for the first time. It is used to determine whether or not the individual telephone number is registered in the system, and when a call is made by dialing an individual telephone number, it is used to indicate whether or not the individual telephone number has been registered in the system. On the other hand, next digit search table pointer 3
indicates the address in memory of the search table for the next digit both at the time of registration and during a call.

The lower digit search table 5 consists of a registration valid display 2 and a telephone unique number display 6. The registration validity display has the same purpose as above,
On the other hand, the telephone number display 6 shows the individual telephone number ijk.
A unique telephone number assigned to a telephone used by a subscriber with a telephone number is registered.

FIG. 2 shows the structure of a correspondence table between individual telephone numbers provided on the memory in the central exchange and exchange numbers and telephone numbers. The correspondence table consists of a search table for each digit as in FIG. 1, and has exactly the same structure as the search table in FIG. 1, especially with the exception of the lower digit search table 7. Lower digit search table 7 shows registration valid display 2. Exchange number display 8. and telephone number display 6
It has the same structure as the lower digit search table 5 in FIG. 1, except for the exchange number display 8. Exchange number display 8
The exchange number, which is the identification number within the exchange network of the exchange that accommodates the telephone used by the subscriber having the individual telephone number ijk, is registered in .

FIG. 3 shows the configuration of a switching system to which the present invention is applied, which mainly consists of a subscriber exchange 30 and a central exchange 31. Both the subscriber exchange 30 and the central exchange 31 have telephones T,
It consists of a subscriber line, a trunk TR, a switch SW, a control device C, a memory M, and a common line signaling device S. Further, the subscriber exchange 30 and the central exchange 31 are connected by a voice line VL and a common line signal line SL, and call control signals for connecting calls are transmitted through the common line signal line SL. , the voice is carried through the voice line VL.

In the memory M, the correspondence table shown in FIG. 1 is stored in the subscriber exchange 30, and the correspondence table shown in FIG. 2 is stored in the central exchange 31 in addition to the correspondence table shown in FIG. However, although this embodiment shows an example in which the central exchange accommodates both the telephone T and the trunk TR, there may also be cases in which only one of them is accommodated, or both are not accommodated, and in these cases, the memory M It is sufficient to store only the correspondence table shown in FIG.

The 4th @ is the 1st in the exchange system shown in Figure 3.
Using the correspondence table shown in FIG.
Individual telephone number registration procedure performed by C.

In particular, in Figure 0, which shows the call control signal sequence between telephone T, subscriber exchange 30 and central exchange 31,
Call control signals are transferred between telephones and exchanges over subscriber lines, and between exchanges over common lines.

First, when a special number indicating registration and an individual telephone number to be registered are dialed from the registration telephone 41, this is notified to the registration local exchange 42 that accommodates the telephone by a calling signal 45 through the subscriber line. Ru. In the registration destination local exchange 42, in the registration process 46, the correspondence table shown in FIG. 1 stored in the memory M is searched based on the received individual telephone number, and if registration is possible, the telephone Stores the telephone number of the telephone that has made a registration request to the telephone number display 6. Further, after setting the registration valid display 2 to "registered", a calling signal 47 is sent to the central exchange 43 in order to update the correspondence table shown in FIG. 2, which is managed by the central exchange 43.
