Abstract

PURPOSE:To simplify a procedure by registering not only a physical subscriber line but a logical link number on the subscriber line on a personal number in a multi-access interface. CONSTITUTION:When the registration of the logical link number from a terminal 1 to a network is performed, the logical link number is attached to every personal number by informing the personal number, and when plural personal numbers are provided in the same terminal 1, plural logical link numbers are attached to every personal number, Therefore, a correspondence table of personal number to (physical subscriber line + logical link number) can be obtained on a network side. When a call, for example, for the personal number of a user 1 is generated, the network side finds the (physical subscriber line + logical link number) in accordance with the personal number from the table, and call setting for the user 1 can be performed by single action, and broadcasting call setting and verification operation for plural terminals 1, 2 can be eliminated. Thereby, the procedure can be simplified.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a logical link numbering type personal communication method G.
This is related to this.

In general, a multi-access interface such as the I5DN user network basic interface, that is, on the network side, the line is centrally managed by the same device, but on the user side, the line is shared by multiple devices and a logical link is set up. By assigning a number, that is, a logical link number, to each of the multiple user devices, and adding the logical link number to the signal, it is possible to send a signal to a specific user device among the multiple devices, or from that specific user device. A method is known in which a user network interface using this method assigns one or more numbers, that is, a personal number, to an individual, and identifies the personal number and the physical subscriber. By registering the correspondence with information such as a number that can identify the place where the call will ultimately be received, such as a telephone line or telephone number, a third party can dial the personal number when making a call, and then the personal number can be registered. By notifying the personal number as a number indicating the request source when making a service request such as making a call, you can use services specific to the personal number, and charge memory specified by the personal number. There is a known personal communication method that allows charges to be accumulated on a person's phone, etc.

The present invention relates to improvements in such personal communication methods.

(Prior art) In the past, a telephone number, etc. that could ultimately identify the physical subscriber line was registered for the personal number given to the individual. If the personal number is shared by multiple people, the personal number must be notified when the network makes a service request such as receiving a call specifying the personal number to the user. There is a possibility that a terminal or person who does not have the right to use that personal number is making a service request such as a response or a call that requires identification with one's personal number, so please do not use a PIN or PIN key. , it was necessary to confirm whether the terminal or person really had the right to use the personal number, that is, to perform authentication.

When a multi-access interface is applied to a physical subscriber line, the user equipment is identified by a logical link number, but it is possible for multiple people to share the same user equipment. In addition, when logical link numbers are reassigned, there is no correspondence between old logical link numbers and new logical link numbers, in other words, there is no way to continuously identify a specific device, so physical In order to identify multiple terminals and multiple users sharing the same line,
When using a personal number, it is necessary to notify the personal number when a service is requested from the network, and to authenticate the personal number when responding to a service request from the network or requesting a service from the user.

FIG. 2 is a flowchart showing an example of a call receiving procedure when a logical link is set for each terminal as in the conventional l5DN user network basic interface.

For a network, there are terminals 1 and 2 that belong to one physical subscriber line, terminal 1 has multiple users (in this case, two users, user 1 and user 2), and terminal 2 has multiple users. Assume that there is one user named 3.

Terminal 1 registers a logical link number with the network. Terminal 2 also registers a logical link number with the network. Next, user 1 on terminal 1 registers a personal number with the network, but at that time, the network also performs authentication to determine whether the person attempting to register truly has the qualifications. This is done at the request of The same applies to users 2 and 3.

As a result, a correspondence table between personal numbers and physical subscriber lines is obtained on the network side.

For example, if a call occurs to the personal number of user 1, the network side determines the physical subscriber line corresponding to the personal number from the table, and sets a call to the personal number of user 1 on the physical subscriber line. At this time, calls are set up in a broadcast manner to multiple terminals belonging to the same physical subscriber line.

Terminal 2 (user 3) receiving this notice realizes that the call setup is not for itself, and releases the call setup. On the other hand, since the call is being set up for himself, user 1 at terminal 1 accepts the call setup from the network. In response, the network performs L'2 verification as to whether the user who accepted the call setup is truly qualified, and user 1 responds to this.

After that, communication will take place, and once it is finished, the line will be released.

[Problem to be solved by the invention]

As explained above, in the conventional system, a logical link number is assigned not to each user but to each terminal. For the personal number given to an individual, numbers such as telephone numbers that can ultimately identify the physical subscriber line are registered, and logical link numbers that identify terminals that share the physical subscriber line are registered. do not.

In reality, the personal number registration procedure uses logical links set for each terminal, so there is no correlation at all, but since multiple personal numbers can be registered on the same terminal, there is no one-to-one relationship. Not only is there no logical link, but if the logical link number is reassigned, the correspondence itself becomes unknown, so there is no point in registering the logical link.

Therefore, each time a service for a personal number is activated, a procedure is required to authenticate whether the correct user is actually requesting or responding, and when a service request is made from the network, it is necessary to verify in which terminal the personal number is registered. Since we do not know, it is necessary to add a personal number to all terminals and notify them of the service request. As already explained with reference to FIG. 2, when a call is received from the network, a call setup signal, that is, a signal that notifies the intention to start communication and the content of the communication at the time of originating or receiving the call is sent via the 15DN user network interface. It is necessary to add a personal number and transmit it to all terminals in a broadcast type (simultaneous broadcast type), and it is also necessary to authenticate the personal number before actually connecting.

Furthermore, when a new call arrives, even if the call is to the same personal number, there is no guarantee that the same user or the same terminal will use the logical link number used in the previous communication, so the call setup signal is broadcast. and authentication cannot be omitted.

The present invention provides a logical link number-assigned personal computer that can simplify procedures such as authentication processing and broadcast-type (broadcast-type) service requests with added personal numbers when providing personal communication on a multi-access interface. The purpose is to provide a method of communication.

[Means to solve the problem]

To achieve the above object, in the present invention, in the multi-access interface, not only the physical subscriber line but also the logical link number on the physical subscriber line is registered for the personal number.

[Effect]

In the conventional system, only the physical subscriber line was registered for the personal number, so when new signal transmission and reception is required, multiple terminals and multiple users connected to the physical subscriber line must be registered. A broadcast-type service request with a personal number added for identification and authentication processing were required, but the method of the present invention eliminates these.

〔Example〕

FIG. 1 is a flowchart showing an example of a call receiving procedure as an embodiment of the present invention.

As shown in the figure, when registering a logical link number from a terminal to the network, a personal number is also notified, thereby assigning a logical link number to each personal number. Even if the same terminal has multiple personal numbers, each personal number has multiple logical link numbers. Even when reassigning logical link numbers, by notifying the personal number from the terminal to the network, the personal number and logical link number will be the same.
The state of 1-to-1 correspondence continues.

As a result, a correspondence table between personal numbers and (physical subscriber line + logical link number) is obtained on the network side.

For example, if a call occurs to the personal number of user 1, the network side will respond to the personal number (
Physical subscriber line + logical link number) can be found from the table and a call can be set up for the user 1 in one go, eliminating the need for broadcast call setup and authentication operations for multiple terminals, which were required in the past. .

Authentication of the personal number is performed when the logical link number is assigned. As an example of the authentication method, an example using an encryption key is shown in FIG. 3, so please refer to it.

If you illegally use another user's personal number to make a service request or respond to a service request from the network, the logical link number will also be used illegally, so if multiple users share the same logical link number. , logical contradictions occur such as receiving a response signal to a signal that the user side did not send, or receiving multiple responses to a signal sent by the network side, and The control logic allows anomalies to be detected.

This situation is shown in the flowchart of FIG. 4, so please refer to it.

As described above, when activating Sars for a personal number, no authentication is required by specifying the logical link number, and when a service request is made from the network for a personal number, the logical link number is fixed, so the broadcasting There is no need for type signal transfer. For example, as shown in Figure 1, when receiving a call from the network, no authentication procedure is required;
Further, the call setting signal may be notified to a specific logical link.

(Effects of the Invention) As described above, according to the present invention, the procedure can be simplified by registering not only the interface number but also the logical link number with respect to the personal number.
