The present invention provides a method for setting a long distance network identification number in a VoIP terminal, and the VoIP terminal determines whether an outgoing network identification number is included in an incoming call number when an outgoing call is attempted. If the number is not included, including a preset long distance network identification number, the VoIP terminal connects the outgoing call to the telephone network (subscriber side telephone network) to which it is subscribed, and the subscriber side telephone network is the outbound network of the outgoing call. Routing the outgoing call to a telephone network corresponding to the identification information (the other telephone network), and the VoIP subscriber and the called party are connected to each other through the other telephone network to perform a call service.

Using the present invention, a non-subscribed long distance network (PSTN) can be easily used when attempting to call a PSTN terminal in a different long-distance area using a VoIP terminal. In other words, the service user is not dependent on the public telephone network of the VoIP service provider, and can select a desired long distance network service provider so that the user can have a right to use a high quality long distance telephone service.

Description

Method for provide service for selecting the toll line network based on VoIP}

The present invention relates to a VoIP-based non-subscribed long-distance network selection service method, and in particular, when attempting a call from a VoIP terminal connected to a VoIP network to a PSTN terminal in a different long-distance area, automatically dials the corresponding long-distance network identification number. This is to minimize the subordinate to the operator and to expand the choice of the long-distance network of VoIP service users.

In general, given that the service provider providing the VoIP service is a long-distance telephone service provider, the service provider is likely to force the service user to use its public switched telephone network (PSTN), which is currently manufactured and provided. Data modems and IP phones that are being used also have no function of selecting domestic long-distance network operators. In this case, the service user can dial and use the long distance network identification number at every call, but there is a problem that adds inconvenience.

Therefore, in the future when VoIP service is universal and public telephone network (PSTN) and VoIP network exist, ordinary VoIP users who do not subscribe to the pre-selection service can easily use the long-distance network service of the operator that provides more stable and high quality service. You need to do it.

Accordingly, the present invention has been proposed to meet the above needs, and when attempting a call from a general VoIP terminal to a PSTN terminal in a suburban area, the user of the general VoIP service is automatically dialed so that the selected long distance network identification signal is automatically dialed. The purpose is to make the public telephone network (PSTN) easy to use.

In order to achieve the above object, the VoIP-based non-subscribed long distance telephone selection service method according to the present invention comprises the steps of setting a long distance network identification number in the VoIP terminal; When the VoIP terminal attempts to make an outgoing call, checks whether an outgoing call is a call for a long distance call and determines whether a predetermined long distance network identification number is included; The VoIP terminal, if the long distance network identification number is not included, including the preset long distance network identification number; Connecting the outgoing call to a telephone network (subscriber side telephone network) to which the VoIP call is subscribed; The subscriber-side telephone network routing the outgoing call to a telephone network corresponding to the long-distance network identification information of the outgoing call; And making a call service by connecting the VoIP subscriber and the called party to each other through the other telephone network.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, a caller may make a call with a receiver 33 using a VoIP terminal 10 capable of making a VoIP-based call. At this time, the caller uses the VoIP-based call service through the VoIP network 21, and the receiver 33 passes through the long distance network (PSTN) 23 to which he / she subscribes and the other long distance network (PSTN) 32 to which he has not subscribed. Call). That is, the receiver 33 is connected to the other long distance network 32.

The VoIP terminal 10 may be configured in various forms. In FIG. 1, a softphone 11 and a VoIP-dedicated phone are connected to the VoIP network 21 using a VoIP program and a modem installed in a user computer system. An example of an IP phone 12 is shown.

To explain the outline of call processing in such a telephone system, a caller, a subscriber of VoIP network operator A, attempts to make a call using VoIP terminal 10, and the call is a device such as a residential gateway (13). After being connected to the VoIP network 21 through the VoIP network provider A is delivered to. At this time, the gateway for call processing 22 acts as a soft-switch to link the VoIP network 21 and the public telephone network, and according to the out-of-town network identification number of the incoming call, the out-of-town service of the corresponding other operators. The call is routed to the network 32 side. Then, it is finally connected to the receiver's telephone terminal 33 through the long-distance network 32 of the other operator.

Referring to Figure 2 will be described the process of making the long-distance call between the originating VoIP terminal and the receiving PSTN terminal according to the present invention.

First, the VoIP terminal should be configured so that the service user can set up the long-distance network to be used. The VoIP terminal allows the service user to input the long distance network identification number through various interfaces such as keys, switches, and menus, and sets / manages the input long distance network identification number as the default long distance network identification number of the service user. (S40-1). Subsequently, when a regional call is attempted to an external public telephone network, the VoIP terminal automatically dials the corresponding long distance identification number.

On the other hand, when the caller attempts to call by entering the caller's number (called party number) in his VoIP terminal (S40-2), the caller checks whether the caller's call is a long distance call (S40-3), If it is not a long distance call, it connects to the receiver through its own public telephone network (S40-7), and if it is a long distance call, it is determined whether a certain long distance network identification number is included therein (S40-4). That is, as the caller directly enters the long distance network identification number, since the service user may select the long distance network that he or she wants to use for each call, in this case, bypasses it as it is (S40-6).

However, when the long distance network identification number is not included in the VoIP terminal, the long distance network identification number set in step S40-1 is included in the call (S40-5). Inclusion here may be understood as meaning dialing a long distance network identification number.

The VoIP terminal then connects the outgoing call to the subscriber side telephone network (S40-8). The soft switch of the subscriber's telephone network checks the long distance network identification number included in the call (S40-9), and if the identification number of the own long distance network is connected to the call using the own long distance network (S40-10). However, when interworking with other long-distance network operators, the call is routed to the corresponding long-distance network (S40-11), and the call is connected to the receiver in the other long-distance network (S40-12). Accordingly, the sender and the receiver can proceed with the call with each other (S40-13).

The VoIP terminal to which the method according to the present invention is applied can be preferably implemented in the form of a soft phone or an IP phone.

In the case where the VoIP terminal is a soft phone, the VoIP terminal may be configured to enter and set a long distance network identification number on a VoIP call computer program installed in a user computer system. In addition, when the VoIP terminal is an IP phone, it may be configured to input and set a long distance network identification number through a key, a switch, a menu, or the like.

However, the method according to the present invention can be applied not only to a VoIP terminal but also to various auxiliary equipments in the same manner.

The present invention is not limited to the above-described embodiments and can be variously modified and implemented by those skilled in the art without departing from the technical spirit of the present invention.

Using the present invention, a non-subscribed long distance network (PSTN) can be easily used when attempting to call a PSTN terminal in a different long-distance area using a VoIP terminal. That is, the service user can select a desired long distance network provider without being dependent on the public telephone network of the VoIP provider, and thus has a right to use a better long distance telephone service. In addition, it is possible to provide a variety of network operators to induce a sense of competition for the improvement of the call service, to provide the best communication service.
