And, the purpose is to prevent the additional charges caused by selective incoming.

In general, a telephone service is intended to be called only by a terminal assigned to a telephone number to which a caller wants to connect. A call forwarding service may be used to forward an incoming telephone connection from another telephone. Only one specific called number can be set in, and the method of setting up call forwarding is complicated, so it is impossible for the receiver to set up call forwarding to different receiving terminals selectively according to the situation of each receiving terminal.

In the call forwarding method, a caller bears a communication fee to a receiving station and charges a communication fee from the receiving station to the terminal after the call forwarding to the receiver, thereby causing double communication charges.

According to the present invention, when the receiver registers the selective incoming service, the receiver can answer the desired number (or terminal) even if the caller makes a call to any of the official phone numbers owned by the receiver. , So that additional charges due to the change of the called number (or terminal) do not occur.

In order to achieve the above object, the present invention operates a communication resale business that possesses all different communication networks of PSTN (Public Switched Telephone Network), mobile communication network, VoIP communication network, or employs other communication companies' communication networks and recruits additional subscribers. Based on the multi-communication service providers that provide PSTN phone, mobile phone and IP phone services to subscribers through the service, selective incoming service is provided to multiple terminals of users who have subscribed to the service. do.

The caller makes a call to the subscriber of the complex communication service from the originating exchange to the recipient exchange of the complex communication service provider, and the recipient exchange is the destination terminal based on the subscriber's call setup information from the SRR server. The call number connection is handled by the network switch of the called terminal.

Receiving Phone Select Sevice on Incomming Call}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a service method that allows a user to freely select and receive a terminal according to a location and a situation of a receiver in a telephone call using a wired / wireless telephone terminal. The present invention relates to a public switched telephone telephone (PSTN) telephone network and an intelligent network. The present invention relates to a telephone communication technology using a communication network and an IP communication network.

Up to now, wired telephone communication network is configured to switch network like PSTN to connect subscriber communication line to switchboard, and then connect call to caller terminal and receiver terminal by sequentially connecting call between exchanges according to identification number of receiver telephone number. As in the intelligent network, it is used as a method of acquiring connection information from a server with a received telephone number at an exchange and connecting a call to a receiver terminal through a receiver exchange.

Mobile communication network is composed of MSC (Wireless Network Switch) to check subscriber's location through HLR (Home Location Register) and VLR (Visotor Location Register) and connect call to base station and repeater's mobile phone.

In addition, in an IP network such as the Internet network, another communication network is connected through a media gateway and a signaling gateway, signaling for a call connection through a soft switch or a gatekeeper, and voice and video between a PC, an IP phone, or a media gateway is performed. A method of connecting a channel by point-to-point communication is used.

In the past, wired / wireless telecommunications service was provided by the telecommunications service provider, in which the operator directly established and operated the telecommunication network, and provided the service directly to subscribers. A telecom resale business is being activated to recruit subscribers and provide services.

In addition, a number porting service is provided that allows a specific telecommunications subscriber to maintain a previously used phone number while changing a subscription to another telecommunications company. For the number porting service, a "number porting common database" has been established that jointly stores the information of subscribers ported by carriers and operates in conjunction with the exchanges of the respective carriers.

In general, people who use a telephone own a plurality of telephones, such as a genetic telephone of a PSTN network, a cellular telephone of a mobile communication network, and an IP telephone of the Internet, and because they live in various places, the receiver receives a call when the other party makes a call. As the situation is different, mobile phones, which are often portable, have become the main means of communication.

When the telephone service user wants to connect an incoming call to another receiving terminal, the original telephone call can be forwarded to another telephone through the call forwarding service.

1 is a block diagram of a conventional communication system for call forwarding. When a telephone service user sets up call forwarding from a destination call terminal 101 to a call forwarding terminal 103 through a receiving station switch 112, the caller terminal is connected. The call originating at 102 is a call connection from the source exchanger 111 to the recipient exchange 112, wherein the recipient exchange obtains the call forwarding information of the receiver from the supplementary service information system 113 and transfers the call. The call is connected to the station exchange 114 and finally the call connection is made to the call forwarding terminal 103.

In the conventional call forwarding method, the caller bears the communication fee 121 from the receiving station to the recipient station and charges the communication fee 122 from the receiving station to the call forwarding terminal 103 again. In particular, there is a problem in that the communication fee is charged, and despite the usefulness of the service, the receiver does not necessarily use the call forwarding service that is charged.

In addition, such a call forwarding setting method can set only one specific forwarding number in the original called terminal, and the call forwarding setting method is complicated, so it is impossible for the receiver to set up call forwarding to different receiving terminals selectively according to the situation of each terminal. Do.

According to the present invention, in a telephone call using a wired / wireless telephone terminal, a telephone call to a telephone number given to a plurality of telephones possessed by a subscriber can be selectively received by a desired terminal according to a user's situation. And, the purpose is to prevent the additional charges caused by selective incoming.

For example, the conventional call forwarding method is a form of "replace the call coming from the home phone into a mobile phone," but the selective call service method according to the present invention is "received by the home phone when you are at home, mobile when you go outside "I get it over the phone, and I get it over the phone at work."

In addition, the present invention solves the problem that the sender and the receiver bears a double call charge when the receiver registers the call forward as described above, so that additional charges due to the selective incoming call does not occur.

In order to achieve the above object, the present invention possesses all the different communication networks of PSTN telephone network, mobile communication network and VoIP communication network, or uses a communication network of other telecommunication companies and recruits additional subscribers to the PSTN telephone to subscribers. Based on the multi-communication service provider that provides mobile phone and IP phone service at the same time, the incoming call service is selectively provided to several terminals of users who have subscribed to the service.

In the case of the PSTN telephone network, communication resale is already actively being made by leasing part of the main carrier network and MVNO (Mobile Virtual), which leases the communication network of the mobile operator of the mobile communication network and runs a virtual mobile communication business. Network operator (virtual mobile telecommunications network operator) business is in the beginning stage, and in the case of VoIP communication network, there is no business restriction in providing telephone service through internet network, so the complex communication service is in the stage of being able to be provided. have.

A telephone (which may be a PSTN number, a mobile telephone number, or an IP telephone number) connecting to the subscriber of the telecommunication service may be called by the recipient exchange of the telecommunication service provider and the SRR ( Subscriber incoming registration) obtains the number (or terminal) information that the subscriber wants to receive from the server and processes the call connection with the corresponding network switch.

The subscriber of the multi-communication service can set the number (or terminal) that he or she wants to receive or miss by using web access, ARS (voice automatic guidance) connection, and terminal menu setting in advance. You can set the rank.

Even if the incoming call number is a PSTN phone number for the call requested by the calling station, the recipient exchange of the multi-communication service provider can pass the call to the wireless network switch if the designated call is a mobile phone. In the absence of a mobile phone, the call can be automatically forwarded to the PSTN phone according to the set priority.

Even if a subscriber of a complex communication service has a PSTN phone, a mobile phone, and an IP phone separately, they are registered together with the same service provider. Once a call is received by the destination country, the need for additional charging is eliminated because the exchange takes place within its own network without having to reconnect to the outside network.

By setting a number (or terminal) to be selectively called for the incoming call in the above manner, the subscriber of the composite communication service can receive the incoming call to the home or company to the mobile phone while moving, When you turn on your phone and turn off your phone, you can automatically receive incoming calls to your home phone.

As described above, the present invention has the following effects by allowing a telephone subscriber to make a call to his / her desired terminal without additional communication charges when the telephone subscriber receives his / her own situation, place, and need.

First, in the present invention, if the receiver designates an incoming call, the receiver can call the desired phone at any time and any place, thereby increasing the call success rate.

Secondly, calls from mobile phones can be received by low-cost IP phones or PSTN phones, thereby reducing communication costs.

Third, due to the limited frequency band in the case of a wireless communication network, as the number of network users increases, the base station is increased together, which causes a large investment cost. Since it is difficult for the caller to know the current location of the receiver, the call is often made by a mobile phone, which leads to an unnecessary occupation of the wireless communication network. According to the present invention, the availability of the mobile communication network can be increased by reducing the unnecessary occupancy of the wireless communication network.

Fourth, the additional communication cost of the receiver according to the call forwarding does not occur, the use of the incoming service can be activated.

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

Figure 2 is a block diagram of the number porting system between carriers of the ACQ (All Call Query) method, the telephone connection proceeds the call processing proceeds in the order of ①-> ②-> ③-> ④.

When the telephone subscriber moves the number from the A communication company to the B communication company, information about the transferred number and the communication company after the movement is registered in the NPDB 214, which is a number porting common database. ① When the other caller makes a call to the number-transferred recipient, the call is not connected to the destination terminal exchange 212 of the A telecommunication company. ② The number transfer from the NPDB 214, which is a number porting common database, at the originating exchange 211. After checking the information, ③ connect the number of B communication company to the destination station exchange (213), and ④ from the destination station exchange to the receiver's phone.

Figure 3 is a block flow diagram showing a preferred embodiment of the selective incoming service according to the present invention call processing proceeds in the order of ①-> ②-> ③-> ④-> ⑤-> ⑥-> ⑦-> ⑧.

Operators that provide selective incoming services are complex telecommunications service providers that have two or more PSTN, mobile, and IP telephone services in the same way as having a wired or wireless network or reselling telecom. The number porting information of subscribers subscribed to the complex communication service provider through number porting is registered in NPDB 312, which is a number porting common database.

An embodiment is a case where a recipient makes a PSTN call 302, a cellular phone 303, and an IP phone 304 together with a composite communication service provider, and designates an incoming call to the PSTN phone 302.

① When caller 301 makes a call, ② Switcher 311 of the calling station requests number porting information of the receiving number from NPDB 312, ③ Receives the recipient subscription network information from NPDB 312, ④ Complex The call is forwarded to the recipient exchange 313 of the communication service provider. ⑤ Receiving station exchange 313 requests subscriber registration information to subscriber receiving server SRR (Subscriber Receiver Register) 314, and ⑥ Receiving station exchange 313 again designated PSTN by subscriber in SRR 314 Receives the phone information, ⑦ connects the call to the PSTN switch (315). When the incoming service subscriber designates the call to the cellular phone 303, the receiving station exchange 313 connects the call to the mobile communication switch 316, and when the incoming call is designated to the IP phone 304, the VoIP exchange ( Call 317). At this time, the receiving station switch 313 of the multi-communication service provider may have a different telephone number requested by the calling station switch 311 and a called number to be connected by the receiving station switch 313. ⑧ The PSTN switch 315, which has received the call from the recipient station switch 313 of the composite communication service provider, connects the call to the receiver's telephone.

4 is received by the recipient terminal switch 313 of the multi-communication service provider and receives the incoming signal to the selective subscriber service subscriber, and is performed by the receiver exchange 313 and the subscriber receiver register (SRR) Subscriber Receiver Register (314). A flowchart illustrating an embodiment of a caller ID selection process.

When the call is received by the exchange (401), it is checked whether there is a number designated by the subscriber of the received number (402), and if there is a designated call, the call is connected (403) to the exchange of the designated number. If there is no incoming call number, the terminal checks whether the incoming call number is set or is turned off (404). If the incoming call is possible, the call is connected to the exchange of the receiving number (405). If the terminal for the receiving number is not available, the terminal having a high incoming priority number is searched (406) according to the incoming call setting of the subscriber, and whether the incoming number can be received (407). Connect 408. If the incoming priority terminal is unable to receive, the missed message is returned to the originating exchange.

FIG. 5 is a block diagram illustrating a configuration example related to a subscriber receiver registration server SRR (Subscriber Receiver Register) that manages call setup information of a selective call service subscriber. The selective incoming service subscriber is the service access channel 503 provided by the service provider and the SSR server 502 in the same way as the socket communication 517 between the terminal and the server after setting in the web service 515, voice guidance 516 and terminal menu. ), The incoming call service can be registered, the incoming priority can be set, and the called terminal can be designated. The SSR server 502 manages the registered telephone information 511, the call specifying information 513, and the call priority information 514 based on the subscriber information 512. When the exchange 501 requests the subscriber's incoming information to the SSR server 502, the SSR server 502 retrieves the subscriber's incoming call setting status and returns the subscriber's highest priority number information.

In the SSR server 502, the subscriber's incoming information may be configured in the form shown in Table 1 below.

Subscriber Phone name number Call forwarding Call forwarding Priority condition communications network Michael Home 070-1000-xxxx Y One On i-net (VoIP) Michael Mobile 010-2000-xxxx Y Yes 2 On m-tel (Mobile) Michael Office 02-3000-xxxx N 3 Off p-tel (PSTN) Tom Hand p 010-4000-xxxx Y One On m-tel (Mobile) Tom Base 070-5000-xxxx Y 2 On inet (VoIP) Jane Family 070-6000-xxxx Y One Off inet (VoIP) Jane Mine 010-7000-xxxx Y 2 On m-tel (Mobile)
