Hereinafter, a method and system for providing a call routing service according to the present invention will be described in detail with reference to the accompanying drawings.

The call routing service providing method according to an embodiment of the present invention may be performed by a call routing service providing system. 1 is a diagram illustrating a network connection of a call routing service providing system.

Call routing service providing system 100 according to an embodiment of the present invention is a call routing for the first user terminal 110 and the second user terminal 120 over an IP network as well as a general public switched telephone network (PSTN) Can provide services. Here, the first user terminal 110 and the second user terminal 120 may include not only legacy terminals (general telephones) but also various terminals such as IP terminals.

2 is a block diagram showing the configuration of a call routing service providing system according to an embodiment of the present invention. Hereinafter, an embodiment of a call routing service providing system according to the present invention will be largely divided into a first embodiment, a second embodiment, a third embodiment, and a fourth embodiment.

<< first embodiment >>

First, the first embodiment will be described below. 2, the call routing service providing system 200 according to the first embodiment of the present invention is the first recording means 210, the second recording means 220, the call receiving unit 230, the first search unit 240, the subscriber determination unit 250, the second search unit 260, and the call setup unit 270 may be configured.

The first recording means 210 is a means for recording list information for a predetermined station number, and the list information includes station number information and corresponding regional information.

Here, "station number information" means information about a predetermined station number, and when an example of what "station number" means is given, for example, it is assumed that the telephone number is "02-555-3333", and the area code "555" located in the middle of "02" and "3333" corresponding to the last 4 digits corresponds to the station number.

On the other hand, "zone information" means information about a given zone, "zone" may be determined by a predetermined criterion predetermined by the service operator. For example, the service operator may set "Suwon", "Yongin" and "Anyang" belonging to the same Gyeonggi-do area in different districts. In addition, it is possible to set the three regions in the same region by changing circumstances, and it is also possible to divide "Suwon" into a plurality of regions again. That is, the concept of "region" as widely used herein is defined by a predetermined criterion and can be changed again by a service operator, and does not mean that it cannot be changed again by a fixed criterion.

FIG. 3 is a diagram showing an example of list information for a predetermined station number recorded in the recording means. Hereinafter, with reference to FIG. 3, how the first recording means 210 may record the list information is described. Explain. The first recording means 210 can record the station number information 301 and the regional information 302 in correspondence with each other. As shown in FIG. 3, in the case of "Suwon" corresponding to the regional number "1", a number corresponding to "690" through "699" is assigned to the station number in the user terminal belonging to "Suwon", and the regional number "2". In the case of "Yongin" corresponding to "Yongin", a number corresponding to "680" through "689" is assigned to the user terminal belonging to "Yongin". In this way, by recording and retaining the list information including the station number information and the corresponding regional information in the first recording means 210 and referring to this, the regional information of the calling party and the called party terminal can be retrieved as described below. have.

According to one embodiment of the present invention, the region may be determined according to the old region code system of 144 regions nationwide that was used before the implementation of the 'regional code regionalization' policy of the Korean government on July 2, 2002. As in this embodiment, when dividing the whole country according to the old area code system, there is an advantage that the effort of dividing the regional area is unnecessary by preparing new standards again.

The second recording means 220 is responsible for recording the subscriber information of the user terminal. The subscriber information may include various information such as phone number information, information about a user terminal, and information about whether to subscribe to an additional service. However, unlike the prior art, the subscriber information does not need to record a region identification number corresponding to the region to which the user terminal belongs. Therefore, the service operator can solve the problem of the prior art that must directly enter the regional identification number corresponding to the domain to which the terminal of the new subscriber belongs each time a new subscriber is added, through which the call routing service according to an embodiment of the present invention Providing system 200 may digest a large number of subscribers to provide a systematic service to the nation or a large area. Meanwhile, the subscriber determination unit 250, which will be described below with reference to the second recording unit 220, may search for subscriber information of the called party terminal and determine whether the subscriber is a subscriber.

The call receiving unit 230 performs a function of receiving call setting information from the first user terminal 201. The call setup information includes first station number information associated with the first user terminal 201 and second station number information associated with the second user terminal 202. Here, the first user terminal 201 means a caller's terminal requesting call setup, and the second user terminal 202 means a called party's terminal to which the call is routed. Meanwhile, the first station number information refers to a station number among telephone numbers assigned to the first user terminal 201, and the first station number information refers to a station number among telephone numbers assigned to the second user terminal 202.

The first search unit 240 searches for first area information corresponding to the first station number information with reference to the first recording unit 210. As described above, according to the call routing service providing system 200 according to an embodiment of the present invention, since the first recording unit 210 records list information including station number information and corresponding regional information, the call receiving unit Upon receiving the call setup information including the first station number information at 230, the area information corresponding to the first station number information can be retrieved, and this area information is referred to as first area information. That is, the first zone information means information about the zone to which the first user terminal 201 belongs.

The subscriber determination unit 250 searches for subscriber information of the second user terminal 202 with reference to the second recording means 220 and determines whether the subscriber is a subscriber. The call setup information includes telephone number information of the second user terminal 202 corresponding to the called party. As described above, the second recording means 220 records subscriber information including telephone number information of the user terminal. For this reason, the subscriber determination unit 250 may determine whether the second user is a subscriber to the service.

When the subscriber determination unit 250 determines that the second user is a subscriber, the second search unit 260 searches for the second area information corresponding to the second station information by referring to the first recording unit 210. As described above, according to the call routing service providing system 200 according to an embodiment of the present invention, since the first recording unit 210 records list information including station number information and corresponding regional information, the call receiving unit Upon receiving the call setup information including the second station number information at 230, the area information corresponding to the second station number information can be retrieved, and this area information is referred to as second area information. That is, the second regional information means information about the regional region to which the second user terminal 202 belongs.

The call setup unit 270 retrieves routing information associated with the first zone information and the second zone information and sets up a call between the first user terminal 201 and the second user terminal 202. According to an embodiment of the present invention, routing information corresponding to a pair of regional information may be maintained in a predetermined means for retrieving the routing information.

Meanwhile, according to an embodiment of the present invention, there is provided a call routing service providing system further comprising a call type determination unit and a billing information generation unit, which will be described with reference to FIG. 4.

4 is a diagram illustrating a part of a call routing service providing system for determining a call type and generating charging information according to the present embodiment. Compared to the call routing service providing system 200 of FIG. 2, the call routing service providing system according to the present embodiment further includes a call type determination unit 401 and a billing information generation unit 402.

The call type determination unit 401 determines a call type associated with the call based on the first zone information and the second zone information, and the charging information generation unit 402 performs the call. Generate charging information for the call based on the type. For example, when the first zone information and the second zone information are the same, the first zone information and the second zone information may be determined to be city calls to generate billing information based on the city calls, and the first zone information and the second zone information are not the same. If not, it may be determined as a long distance call to generate billing information based on the long distance call. In the case of intercity calls, the procedure involved in providing a call routing service by generating the billing information charged to the user and charging the user is relatively simpler than that of the city call. This can solve the problem of equity of billing according to the type of call. Meanwhile, according to one embodiment of the present invention, the call type may be determined and used for billing as well as for various statistics and dial limits.

In addition, according to an embodiment of the present invention, even if the first zone information and the second zone information is not the same, the call routing service providing system that can generate the billing information based on the city call by determining this as a local call This is provided.

According to the present exemplary embodiment, the regional areas may be divided into small regional units, and a plurality of interrelated regional areas are organized into one group according to the degree of association between the divided regional areas (for example, regional adjacency or administrative district division). For example, when setting a regional area call belonging to the group, the call may be determined as a city call to generate billing information based on the city call.

For example, when "Seoul" is divided into a plurality of regions based on "gu", the first region information corresponding to "Gwanak-gu" and the second region information corresponding to "Eunpyeong-gu" are not the same, According to the "Gwanak-gu" and "Eunpyeong-gu" because it belongs to the "Seoul" in the administrative area, the association is recognized as a billing group in the case of setting up the inter-area between the two districts to determine the arc as the city arc and the city It is possible to generate billing information based on the call.

According to the present embodiment, even if the set area is different, if it belongs to the same administrative area, if it belongs to another administrative area but regional proximity between the two areas is recognized, or if it is necessary for convenience in service operation, It is possible to flexibly adjust this without generating uniform billing information according to the region.

<< 2nd Example >>

Hereinafter, a system for providing a call routing service according to a second embodiment of the present invention will be described. Referring to FIG. 2, the call routing service providing system according to the second exemplary embodiment of the present invention includes a first recording unit 210, a second recording unit 220, a call receiving unit 230, and a first searching unit 240. , A second search unit 260, and a call setup unit 270. As a configuration difference between the system according to the second embodiment of the present invention and the system according to the first embodiment, the system according to the second embodiment does not include the subscriber determining unit 250.

The call routing service providing system according to the second embodiment is configured to enable so-called shortest distance routing. In the call routing service providing system according to the second embodiment, the roles of the first recording means 210 and the first retrieving unit 240 are the first recording unit 210 and the first retrieving unit in the first embodiment. Since it is the same as the role of 240, it is sufficient to refer to the description of the first embodiment, and the description thereof is omitted here.

In the second embodiment, the second recording means 220 serves to record the subscriber information of the user terminal as in the first embodiment, but the subscriber information includes location information about the user terminal. There is a difference. This is for the shortest distance routing described below.

In the second embodiment, the call receiving unit 230 performs the role of receiving call setting information from the first user terminal 201 as in the first embodiment, but the call setting information is the first user terminal 201. ), But differs in that it does not include the station number information corresponding to the predetermined regional area information in association with the second user terminal 202. That is, the call setting information includes the incoming telephone number information of the second user terminal 202 corresponding to the called party, as in the first embodiment, but does not include the station number information corresponding to the predetermined area information. For example, when the incoming telephone number information included in the call setup information is "119", the "119" does not mean the telephone number of a specific fire department located in a specific area as a telephone number of a fire department. In this case, the call setup information will be said to not include the area information corresponding to the area information in association with the telephone of the fire department (second user terminal 202).

In the second embodiment, the second retrieving unit 260 refers to the second recording means 220 so that the second user located at the shortest distance from the area corresponding to the station number information associated with the first user terminal 201. It searches for the terminal 202. This is possible because the subscriber information of the user terminal recorded in the second recording means 220 includes the positional information about the subscriber's terminal.

In the second embodiment, the call setup unit 270 routes the call to the second user terminal 202 to set up a call between the first user terminal 201 and the second user terminal 202. do. According to one embodiment of the present invention, routing information corresponding to a pair of regional information and location information may be maintained in a predetermined means for the routing.

According to the call routing service providing system according to the second embodiment described above, when the recipient terminal number information that does not include the station number information corresponding to the area information is received from the calling party terminal, the called party located at the shortest distance from the area to which the calling terminal belongs. You can search for a terminal and set up a call. This second embodiment can be very useful when the caller terminal makes a call setup request to a called party terminal of a special telephone number such as 112, 113, 119, or the like. For example, in the case of "Nonhyeon-dong, Seoul", when the caller dials the called number "119" to the fire station, the caller is located at the shortest distance from the "Seoul Nonhyeon-dong" where the caller is located, not the fire station located in "Seoul Guro-dong". It becomes possible to set a call to a fire station located (for example, a fire station located in Nonhyeon-dong). According to this embodiment, the shortest distance routing is possible according to the type of call setting information as described above, and there is a practical effect of allowing the police station, the fire station, etc. to take a quick action to a user in an emergency situation such as a fire or a crime. . On the other hand, even when the caller dials a destination number including not only special telephone numbers such as 112, 113, and 119, but also other preselection codes such as 082, 083, and 777, the shortest distance routing to the service provider becomes possible.

FIG. 5 is a diagram showing an example of subscriber information recorded in the second recording means held for providing the shortest distance routing service according to the present embodiment. As shown in Fig. 5, the second recording means 220 includes the called party number information 501 of the subscriber station, a location identifier (LSEQ) 502 associated with the called party number information 501, and the subscriber station. Location information 503 relating to a list and a routing information identifier (RSEQ: Routing Sequence) 504. The called party information 501 of the subscriber station may be a called number including not only special telephone numbers such as 112, 113, and 119, but also other preselection codes such as 082, 083, and 777, and a location identifier (LSEQ). Sequence 502 is a predetermined identifier generated as a tool for identifying the called number information 501, the location information 503 is information regarding the location of the subscriber station associated with the called number information 501, and routing information. An identifier (RSEQ) Routing Sequence (RSEQ) 504 is a predetermined identifier generated as a tool for routing the received call to the terminal of the called subscriber.

FIG. 6 is a flowchart illustrating an example of a process for providing a shortest distance routing service according to the present embodiment, and relates to a special telephone number "119" from a caller terminal located in a zone corresponding to "B" in a zone segment number. When the called party number information is received, the call is routed to the called party terminal located at the shortest distance from the region through a predetermined routing information identifier (RSEQ).

<< third embodiment >>

Hereinafter, a system for providing a call routing service according to a third embodiment of the present invention will be described. 2, the call routing service providing system according to a third embodiment of the present invention, the recording means 210 or 220, the call receiving unit 230, the first search unit 240, the second search unit 260 , And the call setup unit 270 may be configured. In contrast with the system according to the third embodiment of the present invention and the system according to the second embodiment, the recording means 210 or 220 is provided with the subscriber information of the user terminal associated with the list information together with the list information for the predetermined station number. The difference is that they record. Unlike recording means in the system according to the first and second embodiments, the recording means in the system according to the third embodiment records subscriber information in association with predetermined regional information included in the list information. Further, the second retrieval unit 260 in the third embodiment corresponds to the regional area information corresponding to the regional area information corresponding to the station number information associated with the first user terminal 201 with reference to the recording means 210 or 220. Search for the second user terminal 202. That is, unlike the second embodiment of searching for the second user terminal 202 located at the shortest distance from the region to which the first user terminal 201 belongs, the second search unit 260 of the present embodiment may be configured to have a first search result. 1 The second user terminal 202 belonging to the same area as the user terminal 201 may be searched for.

According to this embodiment, according to the type of call setting information, routing to a called party terminal located in the same area as the calling party terminal is possible, so that a police station, a fire station, or the like can be quickly sent to a user in an emergency situation such as a fire or a crime. There is a practical effect of taking action. On the other hand, even if the caller dials a destination number including not only special telephone numbers such as 112, 113, and 119, but also other preselection codes such as 082, 083, and 777, the terminal of the operator located in the same area as the caller's terminal. Routing is enabled.

<< fourth embodiment >>

Hereinafter, a system for providing a call routing service according to a fourth embodiment of the present invention will be described. In contrast to the system according to the fourth embodiment of the present invention and the system according to the first embodiment, the station number information associated with the first user terminal 201 that is the originator is included in the call setting information of the first search unit 240. There is a difference that the first zone information associated with the first user terminal 201 is determined as the predetermined zone information when it is determined whether or not it is included and it is determined that it is not included.

According to this embodiment, when the call setup information received from the caller terminal does not include the station number information associated with the predetermined area assigned to the caller terminal (when the caller calls from a foreign country, the caller transmits the caller ID information. (If the caller is calling from a mobile phone, the caller's call is not included in the caller's terminal). Since it is impossible to do so, a call routing service providing system is provided which treats the service as if originating from a certain area according to predetermined criteria set by the service operator.

According to the present embodiment, as described above, the call routing service providing system can fixedly designate outgoing zone information in the incoming route route with respect to the call setting information coming from the incoming route.

Through this, even if the calling information is limited, a systematic call routing service can be provided to the user through a single system.

According to another embodiment of the present invention, in the call routing service providing system according to the fourth embodiment, a call type for determining a call type associated with the call based on regional information associated with a second user terminal 202 that is a called party The call routing service providing system is further provided with a charging information generation unit for generating the charging information for the call based on the decision unit and the call type.

According to the present embodiment, when the call setup information does not include the calling area information as well as the station number information associated with the predetermined area, the call routing service providing system determines the call type based only on the area information of the called terminal. It becomes possible. In this case, there is an advantage that a system that can charge based on only the regional information of the called party's terminal even if not based on the regional information of the calling party's terminal can be constructed.

In the call routing service providing system according to the present invention according to the first to fourth embodiments, session establishment of an IP Internet Protocol-Private Branch Exchange (PBX), an IP-Centrex, a soft switch, a SIP proxy server, or a gateway is performed. It may be a system that supports a Session Initiation Protocol (SIP). IP-PBX is an enterprise voice communication system that provides telephony service based on IP.
