JPH09200814A - Dial-in access number plan for virtual private network - Google Patents

Abstract

PROBLEM TO BE SOLVED: To reduce the number of operations by executing dialing only once at the time of accessing from an off-network in a virtual private network to a member in an on-network by executing number conversion on an intelligent network. SOLUTION: In the virtual private network dial-in access number plan in the intelligent network, a number consisting of ten digits is composed of a service access code 1, an offset code 2, a group access code 3, and an extension number 4. The service access code 1 consists of three digits and determines service on the intelligent network. The offset code 2 consists of one digit and the remaining six digits are divided into the group access code 3 and the extension number 4.

Description

Detailed Description of the Invention

[0001]

The present invention relates to virtual private networks in intelligent networks, and more particularly to dial-in access numbering plans for virtual private networks.

[0002]

2. Description of the Related Art Conventionally, Japanese Patent Laid-Open Publication No. HEI 0-187 is disclosed as a publication in which an extension of a private branch exchange is dialed for connection from a public network.
There is a 4-291595 issue. As the incoming call connection method of the incoming private branch exchange, the additional number dial-in method, the direct dial-in method, and the reception desk incoming call method are generally known, but the call is sent from the public network and the extension of the private branch exchange is dialed. When receiving an incoming call, the number was converted by the private branch exchange.

[0003]

However, in the virtual private network in the intelligent network, as shown in FIG.
As shown in (A), off-net-on-net access from outside the virtual private network to a subscriber of the virtual private network is a
Since there are many cans, the load on the system is large.

The reason for this is that since the number of digits of the group number and extension number is variable in the access call to the virtual private network in the conventional intelligent network, when the group number and the extension number are dialed at once, the separation between them is not known. So, I used the method of dialing twice.

It is an object of the present invention to limit the number of dialing operations by the subscriber to only once when accessing an on-net member from off-net of a virtual private network.

Another object of the present invention is to perform number conversion on an intelligent network when a call originates from outside the virtual private network and a dial-in call arrives at an extension of the virtual private network group.

[0007]

A dial-in access number plan for a virtual private network according to the present invention has a program and data for an application service, activates the program in response to a service request from the exchange, and issues a command to the exchange. Computer SCP for controlling service, and the SCP
An exchange SSP having a function of executing a call connection operation according to an instruction from a computer, and a computer S that manages programs and data for the application and operation management of the SCP.
A dialing plan for dial-in access of an MP and a virtual private network corresponding to members of a specific group in an intelligent network IN having a subscriber telephone as a main component, the dialing of a subscriber who is a member of the virtual private network. At the time of calling, the member of the virtual private network is directly accessed and connected by the outgoing dialing number that is dialed only once.

Further, the outgoing dial number has a service access code for determining the type of service, an offset code for determining the number of digits of the extension number, a group access code, and a dial number connected by the extension number, or shortened. The dial number has a dial number connected by a service access code, an offset code, a group access code, and an extension number by converting the speed dial.

The dial-in access of the virtual private network according to the present invention is such that when the off-net member of the virtual private network accesses an on-net member, the subscriber dials a multi-digit number only once to access the service. A code, a group number, and an extension number are sent out to be connected to the member.

[0010]

1 is a block diagram of a dial number plan according to an embodiment of the present invention.

The numbering plan for virtual private network dial-in access is a 10-digit number, which is composed of a service access code 1, an offset code 2, a group access code 3, and an extension number 4. The service access code 1 is a 3-digit number that determines the service on the IN. The offset code 2 is a one-digit number and separates the remaining 6-digit group access code 3 and the extension number 4.

FIG. 2 is a flow chart showing the operation.

From the 10-digit number dialed by the subscriber,
First, the service access code 1 is taken out and the service is determined. (S-1) In the case of the virtual private network dial-in service (S-2), the digit number 4 of the extension number is obtained from the offset code 2.

The extension number is determined from the calculated number of digits.
(S-4) The remaining number becomes the group access code 3 and determines the group number. (S-3) The database is accessed using the group number and extension number 4 as keys (S-6), and the called number is determined. (S-
7) Connect to the called number. (S-8)

[0015]

As described above, since the extension number and the group number can be determined by dialing once by having the dial number according to the numbering plan of the present invention, the group number and the extension number are divided into two and dialed. There is an effect that the operation sequence required for connection is reduced because there is no need to do so.

Further, in the conventional virtual private network off-net-on-net access of FIG. 3A, the sequence has 4 transactions, but in the virtual private network dial-in access of FIG. Since processing can be performed, there is an effect that the load on the system can be reduced.
