Abstract

PURPOSE: A method of servicing a representative group number using an intelligent network is provided to give a representative group number to input an extension number of a group through another announcement for an external telephone, thereby enabling a call connection and distinguishing personal purpose from business purpose by using a personal number, a representative number, and an extension number. CONSTITUTION: A transmitter attempts a call by inputting a predetermined telephone number(S100). A service control device decides whether the telephone number is a group number representing many personal numbers(S120). If so, the service control device delivers a predetermined announcement to the transmitter through an ARS, and stands by(S140-S260). If a specific one-digit number is inputted by the transmitter, the service control device delivers another announcement, and if more than two-digit personal numbers are inputted, the service control device confirms a base station position of a corresponding terminal(S280). If the base station position is confirmed, the service control device opens a call between the corresponding terminal and the transmitter to make the call(S300-S320).

Description

Service method for group key number using intelligent network

The present invention relates to a virtual private network (VPN), in particular by assigning a group representative number to a group customer of mobile communication using a personal number and representative number and extension number for personal and business phone use This invention relates to a group representative number service method using an intelligent network.

In general, a virtual private network service is an intelligent network service that enables a subscriber to use a private network using a unique number system defined by a customer without using a switching network.

1 is a configuration diagram of a general virtual private network (VPN), which will be described with reference to the following.

First of all, the access type includes a direct access that directly accesses an intelligent network service system through a base transceiver station (BTS) and a mobile switching center (MSC), and is registered in a virtual private network (VPN). There is a remote access for accessing an intelligent network system through an authentication procedure using a virtual private network card from an unregistered terminal (public telephone, a general telephone, a personal communication system (PCS) terminal, etc.).

Next, the call type includes an On-Net Call in which a virtual private network subscriber (On-Net) calls the called party's virtual private network subscriber (On-Net) using a predetermined number system, and a virtual private network. When the subscriber (On-Net) is calling by using the PCS or Public Switched Telephone Network (PSTN) telephone number with the off-net terminal that is not joined to the virtual private network. Off-Net Call that transmits to PSTN phone number and service that allows virtual private network users to access their temporary private network from communication terminals in non-virtual private network using password. In addition, there is an off-net access called by a non-registered external (PCS or PSTN subscriber) terminal to a provisional private network subscriber (On-Net).

Next, the arc flow is as follows.

In case of direct access, the subscriber dials a PNP (Private Numbering Plan), and in the case of remote access, SAC (Service Access Code) + PNP.

If the subscriber number is analyzed and the subscriber number is determined by joining the subscriber number, the next call processing is performed. If not, the announcement is broadcasted and the call is terminated.

After accessing the DB, the on-net subscriber converts to the registered number, and the remote access subscriber converts to the registered number and transmits it, and generates the billing data after the call ends.

Next, the hypothetical private network (VPN) can be sent to the extension number (zzzz) by assigning a separate extension number between subscribers in the group set even if the station number is different. That is, it is sent to the last digit of xxx-yyy-zzzz.

On the other hand, CUG (Closed User Group) as a supplementary function is a function to differentiate screening authority by creating a screening group, and include the same phone number in one group in the group with the next four digit number. You can make an extension call with the subscriber. In other words, if the station number is the same in xxx-yyy-zzzz, only the extension number zzzz can be sent.

As such, the general hypothesis private network was given only individual numbers and could be used for personal telephone use rather than business use.

Therefore, the present invention was devised to solve the above-mentioned problems, and by assigning a group representative number, a call can be connected by inputting an extension number within a group through a separate announcement for an incoming call. The purpose is.

At this time, the group representative number is assigned to the group subscriber can be used as the representative number (for example, xxx-yyy-zzzz). That is, each group selects one representative number from xxx-yyy-0001 to 9999 as the representative number.

In addition, the service exchanger 200 is a type of exchange that connects a service user and an intelligent network, and is a network switching device in which an intelligent network S / W is embedded, and can perform call analysis (intelligent network call recognition) from a subscriber.

In addition, the service control device 300 as a function to control the overall intelligent network service, and manages and controls the subscriber DB such as representative number, extension number, unique number (subscriber mobile number). That is, even if the caller does not know the extension number after accessing the representative number, the service control can be performed by inputting "0" instead of 4 digits in the guidance message "Enter the 4 digit extension number" by the intelligent peripheral device (ARS) 400. The device 300 determines that the caller requests the phone information in the group and causes the intelligent peripheral device 400 to have information registered in the group representative number "Kim ** is 1234, Park ** is 1235 ... If you send a voice ARS of ", the caller dials the desired four-digit extension number and the call is connected with the corresponding receiver.

In addition, the service control device 300 may have a different service control device for each service, it is easy to add and change services.

When the caller enters the extension number 4 or 0 according to the announcement, the inputted information is connected to the service control device (SCP) 300 and the input number is 4 digits. Check the current position (base station position of the switch) of the mobile terminal 120 or the landline telephone 140 matching the number.

When the input number is 0, the service control device (SCP) 300 provides a guide message for entering a number and an extension number corresponding to the extension number of each group stored through the intelligent peripheral device 400. do. In this case, the members belonging to the extension group select a separate extension number of four digits regardless of the current unique personal number, and the intelligent peripheral device 400 sends the caller the extension number, department and name of the member in the group. Information such as voice announcements.

In addition, the intelligent peripheral device 400 provides the interrelationship between the user and the intelligent network with functions such as an interface device with the subscriber, a special announcement, voice recognition, voice synthesis, voice recording, and a fax receiver.

In accordance with the announcement, the four-digit number is input, and the inputted four-digit number is requested to the subscriber location registration apparatus 500 to check the current position of the matching number.
