JPS63105555A - Transferring system for sender subscriber identification information - Google Patents

Abstract

PURPOSE:To facilitate the connection between communication networks having different numbering systems by obtaining sender identification corresponding to a dial number from registered information and transferring a call when a sender subscriber makes dialing. CONSTITUTION:When a sender subscriber A dials an access number AN1 of a relay communication network NW1 and a telephone number DNB of an incoming subscriber B, a subscriber exchange 1 accommodating the subscriber A identifies the access number AN1 from the dial number to decide the relay communication network NW1 and obtains a sender translation word ORTLR from an accommodated location LEN of the sender subscriber A. Then the number AN stored in a DNORID is extracted and the extracted ORID1 is sent to the relay communication network NW1. The relay network communication network NW1 identifies whether the sent ORID1 is a contracted subscriber or not and connects it to an incoming subscriber B when the subscriber A is the contracted subscriber. Thus, the relay communication network provides unique sender subscriber identification information independently of the sender subscriber identification information of a terminal communication network.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an automatic switching system that connects different communication networks, and in particular, an automatic switching system that is suitable for connecting communication networks with different numbering systems. This invention relates to a calling subscriber identification information transfer method.

[Conventional technology]

In conventional automatic switching equipment, there is a one-to-one correspondence between the calling terminal and the calling subscriber's identification information, and depending on the number dialed by the caller, it is determined whether or not the calling party's identification information can be transferred, and whether the calling party's identification information needs to be transferred. In this case, all fixed and unique caller identification information is transferred.

As a document related to the prior art, for example, there is "Introduction to Electronic Exchange Programs" published by the Institute of Electronics and Communication Engineers (March 15, 1976).

[Problem that the invention seeks to solve]

The above-mentioned conventional technology does not consider the case where terminals are accommodated in a plurality of different communication networks (relay communication networks). In this case, in the prior art, it is necessary for the valley communication network to identify the originating subscriber using the same information as the originating subscriber identification information of the terminal network that accommodates the originating subscriber terminal; There is a problem in that it is not possible to assign caller identification information unique to the communication network. However, there is a problem in that it is not possible to connect communication networks with different numbering systems.

An object of the present invention is to provide a calling subscriber identification information transfer system that allows connection between communication networks with different number systems.

[Means to solve the problem]

The above purpose is to register the numbers dialed by the calling subscriber and the corresponding caller identification information for the calling subscriber, identify the dialed numbers of the caller, and make the corresponding call from the dialed numbers. This is achieved by obtaining personal identification information from registered information and forwarding the obtained information.

[Effect]

When a calling subscriber dials, the caller identification information corresponding to the dialed digits is obtained from the registered information, and the requested caller identification information is transferred. By registering this as information, it becomes possible to connect between communication networks with different numbering systems.

〔Example〕

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

Figure 2 is a conceptual diagram of the network structure between different carriers.The terminal carrier network NWA accommodates subscribers A and B, and the terminal carrier network NWo accommodates subscriber C. has been done. Subscribers A and B are accommodated in subscriber exchanges fil and 3 in the terminal carrier network NWA, respectively, and subscriber C is accommodated in the subscriber exchange 2 in the terminal carrier network NWo. NW□
INW2 is a different relay communication network, and subscriber A has a contract with both relay communication networks NW and NW2゜, and subscribers B and C have a contract with only one of the relay communication networks NW□ and NW2, respectively. are doing.

DNA, DNB, and DNo are the telephone numbers of subscribers A, B, and C, respectively. In such a network configuration, when a call originates from subscriber A and arrives at subscriber B via communication network NW□, the call is sent from subscriber exchange 1 to relay communication network NW1 by AN□+DN.
When information of □ is transferred from B+OkL and arrives from subscriber A to subscriber C via communication network NW2, the information is transferred from subscriber exchange 1 to relay communication network NW2 as follows: A1'J2 + D t'so+ORI i)2 When a call arrives from subscriber C to subscriber A via communication network NW2, information of 3 is transferred from subscriber exchange 2 to relay communication network NW2 from AN2+DNA+0. In this embodiment, the transfer information is composed of n from ANfl+DNx+OR. Here, ANx indicates the access number used by the originating subscriber to access the relay communication network, and 0HJDn indicates the originating subscriber identification information corresponding to that ANx.

FIG. 1 is an explanatory diagram of the case where the caller registers the numbers dialed and the corresponding calling subscriber identification information.

In Figure 1, 0RTLR is the calling subscriber's accommodation location LE.
DNORID indicates the originating subscriber identification information registration table in which the originating subscriber identification information corresponding to the dialing number of the originating subscriber is stored. By storing the address of the originating subscriber identification information registration table DNO-ID in this originating translation word 0RTLR,
It is possible to obtain the corresponding calling subscriber identification information registration table from the calling subscriber's accommodation level [LEN] and to obtain the calling subscriber correspondence from the calling subscriber's dial information. Incidentally, the originating subscriber identification information registration table shown in FIG. 1 is for subscriber A.

Next, a procedure for connecting subscriber A to subscriber B via relay communication network NW1 will be explained according to the flowchart in FIG.

First, when calling subscriber A dials the access number AN1 of relay communication network NW1 and the telephone number DNB of called subscriber B, subscriber exchange 1 accommodating subscriber A dials the access number AN□ from among the dialed digits. The relay communication network NW is identified and determined (step 1), and then the originating translation word 0RTLR is obtained from the accommodation location LEN of the originating subscriber A (step 2). A calling subscriber identification information registration table DNORID corresponding to calling subscriber A is obtained from the obtained 0RTLR (step 3).

Next, step 4. Extract the AN stored in DNORID. Step 6), compares the dialed access number AN1 with step 5), and extracts caller identification information 0RIi)□ corresponding to the matched AN (step 7). This extracted 0RID code is sent to the relay communication network NW□ (step 8). The relay communication network NW□ identifies whether or not the sent 0RID1 is a contract subscriber, and if it is a contract subscriber, it connects to the called subscriber B.

In the same way, from the originating subscriber A to the relay communication network NW2.
When connecting to the terminating subscriber C, the access number AN2 of the subscriber exchange 1 that accommodates the originating subscriber A is transferred to the relay communication network NW2 from the originating subscriber identification information OR. Send. Also, subscriber C is connected to relay communication network NW.
Similarly, when relaying 2 and receiving a call to subscriber A, subscriber C
The exchange 2 that accommodates the relay communication network access number AN
From 2 to the originating subscriber identification information OR, 3 to the relay communication network N
Send to W2.

By associating the relay communication network access number dialed by the calling subscriber with the calling subscriber identification information sent to the relay communication network in this way, it is possible to make calls compatible with the relay communication network accessed by the calling subscriber. Personal identification information will be transferred.

This allows the relay communication network to assign its own originating subscriber identification information, regardless of the estrous subscriber identification information of the terminal communication network. That is, even if a telephone number is used as the calling subscriber identification information of the terminal communication network, the relay communication network can use its own unique information such as an address code. Further, even if the originating subscriber identification information of the terminal communication network is changed, if the system according to the present invention is used, the relay communication network does not need to change the originating subscriber identification information.

〔Effect of the invention〕

According to the present invention, since the originating subscriber identification information corresponding to the communication network is transferred, the relay communication network can provide unique originating subscriber identification information different from the originating subscriber identification information of the terminal communication network. In addition, it facilitates connection between communication networks with different numbering systems, and also eliminates the need to change it in the relay communication network even if the originating subscriber identification information in the terminal network changes. be.
