Description

Presence-based lifetime number service system and its method {PERMANENT PRIVATE NUMBER SERVICE SYSTEM BASED ON PRESENCE AND METHOD THEREOF}

The present invention relates to a lifetime number service system, and more particularly, to a presence-based lifetime number service system and a method for designating a call priority based on a presence in a lifetime number service.

Recently, with the spread of the Internet, the use of Voice over Internet Protocol (VoIP) using an IP network has been greatly increased. Such an internet phone enables a call to an existing wired or wireless network through a dedicated program installed in an internet phone terminal, for example, a computer. However, there is a fatal problem that such a telephone cannot be answered at present because a telephone number is not given to the Internet telephone.

In order to overcome this problem, the numbering is made according to a separate numbering system for Internet telephony so that not only the transmission but also the reception is possible.

On the other hand, the lifetime number service is a service currently provided as part of the supplementary service by some carriers. In the case of a specific company, '0505' is used as an identification number, and a seven-digit number is given to give a lifetime number. In this lifetime number, the user can receive a call in that order by registering the wired / wireless telephone numbers that are already used. For example, '02 -333-xxxx 'is registered as the first number in the lifetime number,' 011-222-xxxx 'is registered as the second number, and the first number has priority over the second number. If is set to be high, when the connection to the first number for a certain period of time is automatically connected to the second number by the user can receive an incoming call using his lifetime number.

However, such a lifetime number service is not provided for the Internet phone, which is rapidly increasing in recent years as described above, and there is a problem in that it does not receive benefits such as call charge reduction due to the use of the Internet phone.

As a technique for solving such a problem, Korean Patent Publication No. 2003-0027556 of Katy Co., Ltd., "An Apparatus and Method for Call Processing of Internet Phone Using H.323 Protocol and SIP Protocol" and Patent No. 10-0406571 "An Internet terminal receiving method and system of an intelligent terminal using a lifetime number" is disclosed, all of these technologies are characterized in that to receive a lifetime number service using an Internet telephone. However, in the case of these technologies, when a user registers information such as an IP address that can connect a call to an Internet phone with a lifetime number, the user can use the current Internet phone by setting a fixed priority as in the conventional lifetime number service. Even if the priority is low, there is a problem that the call is connected to the Internet phone after attempting to connect to another phone terminal registered to have a high priority.

On the other hand, the Internet messenger, which is rapidly spreading in recent years, is a system that instantly exchanges simple text information between computers connected to the Internet using 3GPP's Instant Messaging Presence Protocol (IMPP). To this end, the messenger system manages the presence of the user's current state, and the user's presence information includes online, offline, away, and busy. This presence is shown in the buddy list of others who have set themselves as a buddy, letting them know when to send a message.

However, IMPP in such an Internet messenger system only provides a message exchange service between computers, and does not provide a variety of services in cooperation with the above-mentioned lifetime number service, Internet telephone, or telephone service to a wired / wireless network.

Therefore, the technical problem of the present invention is to solve the above problems, by using the presence concept used in the IMPP of the Internet messenger to connect the call by specifying the priority according to the presence of the telephone number registered in the lifetime number To provide a presence-based lifetime number service system and method thereof.

Presence-based lifetime number service system according to one feature of the present invention for achieving the above object,

An exchange providing a lifetime number connection service to wired / wireless telephone terminals and Internet telephone terminals; And a presence look table connected to the exchange to store and manage the presence of the telephone number registered as the lifetime number of the subscriber of the lifetime number connection service. The telephone number of which the presence is set is searched and provided to the exchange among one or more telephone numbers registered for the lifetime number to be input, and the exchange exchanges the lifetime number input from the wired / wireless telephone terminal or the Internet telephone terminal. It is characterized by providing a lifetime number connection service by setting a call to a telephone number having a priority based on the presence provided from the presence lookup table.

Presence-based lifetime number service method according to another feature of the present invention,

a) receiving a lifetime number from a wired / wireless telephone terminal or an internet telephone terminal; b) searching for a telephone number for which a presence is set among telephone numbers registered for the received lifetime number; c) setting a call path between a telephone terminal corresponding to the telephone number to which the presence is set and a telephone terminal to which the lifetime number is transmitted when the telephone number to which the presence is set is searched in step b); And d) searching for a telephone number having the highest priority set in advance by the user among the telephone numbers registered for the lifetime number when there is no telephone number for which the presence is set in step b). Establishing a call path between the telephone terminals which have transmitted the number.

Hereinafter, a presence-based lifetime number service system according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a presence-based lifetime number service system according to an embodiment of the present invention.

As shown in FIG. 1, the presence-based lifetime number service system 100 according to an embodiment of the present invention includes a switch 110 and a Presence Lookup Table (PLT). 120.

The exchange 110 connects the wired / wireless terminals 300 and 310 connected through the wired / wireless networks 200 and 210 to the Internet telephones connected through the Internet network 220, that is, the VoIP terminal 320. It provides a service and a lifetime number service.

Lifetime number can be given using a specific identifier as in the prior art, in the embodiment of the present invention will be described as giving the Internet telephone number as the lifetime number.

The exchange 110 receives an inbound call from the wired / wireless terminal 300 or 310 or the internet telephone 320, and the PLT 120 when the receiver's telephone number determined by the incoming call is a lifetime number. ) Receives the telephone number registered as the recipient's lifetime number and forwards the call to the network of the telephone number. At this time, the exchange 110 receives a call from the highest priority telephone number among the telephone numbers registered as the lifetime number of the receiver from the PLT 120, and connects the call. If the call is not connected to the corresponding telephone number, Attempt to connect the call to the phone number of priority. Here, the telephone number having the highest priority among the telephone numbers registered as the lifetime number of the recipient is the telephone number to which the presence is set. If the presence is not set, the priority is set according to the predetermined priority.

The PLT 120 is a database server that stores subscriber information. The database includes a user ID, a telephone number, an IP, a presence, and the like. Here, the user ID is a lifetime number.

When the PLT 120 receives a request for a telephone number having a presence for a user ID from the exchange 110, the PLT 120 searches a database and retrieves a telephone number having a presence from among telephone numbers registered as the lifetime number of the user. Transfer to exchange 110. At this time, if the telephone number having the presence is an Internet telephone number, the IP of the corresponding Internet telephone is also delivered.

On the other hand, if there is no telephone number having a presence, the PLT 120 transfers from the telephone number of the highest priority according to the priority set by the receiver among the telephone numbers registered as lifetime numbers to the exchange 110.

The database configuration of the PLT 120 is as follows.

The PLT 120 database is composed of a user ID, a telephone number, an IP, a presence, and an order, but another database may be added if necessary according to the configuration of the lifetime number service system according to the embodiment of the present invention. Can be.

Here, the user ID is an Internet telephone number which is a lifetime number. The telephone number can be any telephone number, such as a landline telephone number, a wireless telephone number, or an Internet telephone number. IP is data that is specific to Internet telephony and is an IP with an active telephony. Presence is a logical value (0 or 1) as to whether or not the user can currently use the phone number. Also, the presence may only have a logical value of '1' as long as the telephone number has changed most recently. The order indicates the telephone connection order specified by the user, that is, the priority. The smaller the order, the higher the priority, but vice versa.

Table 1 below shows an example of the PLT (120) database.

In the lifetime number "070-1111-1111", three telephone numbers are registered, namely, an Internet telephone number, a landline telephone number, and a wireless telephone number, and the Internet telephone number has a presence. In this case, when there is a telephone number request for the lifetime number from the exchange 110, the PLT 120 exchanges the Internet telephone number " 070-1111-1111 " and its IP " 255.211.222.10 " 110). If the call to this number fails, the telephone number "02-333-2222", the telephone number with the lowest order, that is, the telephone number with the highest priority, among the telephone numbers that do not have a presence, are exchanged. Is passed to 120.

Similarly, in the case of the lifetime number " 070-1111-1112 ", it is apparent that the radio telephone number " 016-123-4567 " is first provided to the telephone number request from the exchange 110 in reference to the above description.

Hereinafter, a presence-based lifetime number service method according to an embodiment of the present invention will be described with reference to FIGS. 2 and 3.

2 is a flowchart of a presence-based lifetime number service method according to an embodiment of the present invention.

Referring to FIG. 2, the caller 400 inputs the lifetime number of the receiver 500 by using his or her wired / wireless terminal or an internet phone to call the receiver 500 having a specific lifetime number (S10).

The exchange 110 checks the lifetime number input from the caller 400, and then transfers the lifetime number input to the PLT 120 and requests a corresponding presence-based telephone number (S20).

The PLT 120 searches for a registered telephone number for the lifetime number inputted from the exchange 110, and if there is a telephone number having a presence among the retrieved telephone numbers, the telephone number is first transmitted to the exchange 110. (S30). At this time, if the telephone number having the presence is an Internet telephone, the corresponding IP is also transmitted to the switch 110.

Next, the exchange 110 requests the call setup from the receiver 500 of the telephone number transmitted from the PLT 120 (S40), and when the call setup is completed according to the response from the receiver 500 (S50), the caller ( 400 to establish a call path between the recipient 500 having a presence to make a call through a lifetime number (S60).

3 is a flowchart illustrating another example of a presence-based lifetime number service method according to an embodiment of the present invention.

Referring to FIG. 3, a process (S100 ˜ S130) of requesting a call setup to a receiver 500 corresponding to a presence-based telephone number by inputting a specific lifetime number by the caller 400 is described with reference to FIG. 2. Since it is the same as the process (S10-S40), it abbreviate | omits here for convenience of description and it demonstrates after that.

If there is no response from the receiver 500 having a presence in response to the call setup request from the exchange 110, and the call setup fails (S140), the exchange 110 returns the lifetime number input from the caller 400 again. While transmitting to the PLT 120, the corresponding priority-based phone number is requested (S150). At this time, the priority-based phone number request is the phone number with the highest priority (determined by order) among the phone numbers registered for the lifetime number except the phone number with the presence of a prefix. Say what you ask for.

The PLT 120 searches for a registered telephone number for the lifetime number inputted from the exchange 110, and then, among the retrieved telephone numbers, the telephone number having the smallest order data among the remaining telephone numbers except for the telephone number having a presence, That is, the highest priority telephone number is transferred to the exchange 110 (S160). At this time, if the phone number having the highest priority is an Internet phone, the corresponding IP is also transmitted to the switch 110.

Next, the exchange 110 requests the call setup from the receiver 600 having a high priority without the presence of the telephone number delivered from the PLT 120 (S170), and sets up the call according to the response from the receiver 600. When this is completed (S180), by setting the call path between the caller 400 and the receiver 600 to make a call through a lifetime number (S190).

On the other hand, the user can change the presence information with respect to the telephone number registered in the PLT 120 in a variety of ways, in the case of the presence change method, the method of automatically changing based on settings and other contexts and subscriber behavior There is a way to change manually.

First, the method of automatic change is demonstrated.

First, as a method of automatically switching when the VoIP terminal is logged in, a user who used the mobile terminal 300 or the landline 310 may automatically use the VoIP terminal 320 when the VoIP terminal 320 logs in. It's a way to change to a legend.

Specifically, first, when a user who is using existing wired / wireless telephones 300 and 310 drives the VoIP terminal 320, the user is given permission to use the VoIP terminal 320 through an authentication process. As such, if authentication succeeds, the presence of the corresponding telephone number in the PLT 120 is changed so that the call 110 can automatically route the call to the VoIP terminal 320. Thereafter, the call may be first received by the VoIP terminal 320 for the corresponding lifetime number.

Secondly, when there is no response for a period set by the user, the method automatically switches. The user reacts through the operation of the VoIP terminal 320 for a specified initial time value or a set time, for example, a mouse of a computer. And if there is no reaction through the keyboard or the peripheral input device, the VoIP terminal 320 is a method for automatically switching to a subscribed wired or wireless telephone.

Specifically, first, when the user activates the setting of the automatic presence switching function of the VoIP terminal 320 and inputs the automatic switching time, the VoIP terminal 320 of the VoIP terminal 320 during the specified initial time value or the automatic switching time input by the user is specified. If there is no response through the operation, the VoIP terminal 320 requests the exchange 110 to change the presence. Accordingly, the exchange 110 confirms that the VoIP terminal 320 requesting the presence change is authenticated, and requests the PLT 120 not to have the presence of the telephone number of the VoIP terminal 320. The lifetime number is then serviced based on priorities as before.

Third, as a presence automatic conversion method using a positioning system, a mobile terminal 300 is a VoIP terminal (using a positioning system that checks the position of the mobile terminal through a base station of the wireless network 200). 320, the mobile terminal 300 automatically changes the presence of the call so that the mobile terminal 300 can preferentially receive the call when the user leaves the area of use.

Specifically, when the user carries the mobile terminal 300 while using the VoIP terminal 320 and moves out of the use area of the VoIP terminal 320 to another region without any setting, the base station is the user's mobile terminal. Detecting the movement of the 300, the switch 110 requests the PLT 120 to change the presence of the VoIP terminal 320 and the presence of the mobile terminal 300, and the PLT 120 requests the VoIP terminal ( The presence of 320 is eliminated, and the mobile terminal 300 is changed to have a presence, so that the mobile terminal 300 can preferentially receive a call for a lifetime number.

Next, the manual change method is explained.

First, a method of manually switching a user directly in a VoIP terminal 320 environment, and a method of manually switching a user directly by providing a function of changing the presence information of the user in the VoIP terminal 320 environment. .

Specifically, when the user activates the 'receive by wired or wireless telephone' function while the user is using the VoIP terminal 320, the VoIP terminal 320 transmits a specific wired / wireless service for the lifetime number to the PLT 120 through the exchange 110. Presence change requests can be made to enable preferential call routing to the telephone, and then preferentially receive calls on wired and wireless telephones registered for lifetime numbers.

Secondly, it is a method to change by using ARS (Automatic Response System), to provide ARS for setting the presence of a specific telephone number, and to select a menu number by accessing ARS using a wired or wireless telephone. This is how you change your presence.

Specifically, first, a user who wants to change his / her presence is connected to an assigned ARS number using a wired or wireless telephone, and then selects a menu for changing the presence according to the ARS. Thereafter, if the desired setting is made, the exchange 110 requests the PLT 120 to change the presence of the corresponding setting, and the PLT 120 changes the presence of the telephone number requested from the exchange 110. After that, the lifetime number service is performed according to the changed presence information.

Third, a method of changing the presence by using the VM (Virtual Machine) application of the mobile terminal 300, a method of changing the presence by driving the presence of the change VM application downloaded to the mobile terminal (300) to be.

Specifically, the user of the mobile terminal 300 first downloads the VM application for changing the presence through the mobile terminal 300 according to a receiving method, and then drives the corresponding VM application. After that, if the desired setting is made, the exchange 110 checks the presence set through the PLT 120, and if the condition is met, the presence of the call to the subscribed wired / wireless telephones 300 and 310 to enable call routing by lifetime number is possible. To change. Thereafter, the call may be preferentially received by the wired / wireless telephones 300 and 310 subscribed to the lifetime number.

Fourthly, a method of changing a presence using wireless Internet is a method of changing a presence by connecting to wireless Internet where a user can set a presence for a specific telephone number.

Specifically, the user first accesses the wireless Internet through the mobile terminal 300, and then selects a menu for changing the presence of a presence. Then, if the desired setting is made, the exchange 110 checks the presence set through the PLT 120, and if the condition is met, the presence of the call so as to enable call routing by lifetime number to the subscribed wired / wireless telephones 300 and 310. Change it. Thereafter, the call may be preferentially received by the wired / wireless telephones 300 and 310 subscribed to the lifetime number.

Fifth, a method of changing a presence by sending a Short Message Service (SMS) is a method of changing a presence by transmitting an SMS to a specific service telephone number through the mobile terminal 300. At this time, it is desirable to be processed regardless of the message content.

Specifically, first, the user transmits an SMS in which a specific telephone number is written to the assigned number using the mobile terminal 300. Upon receiving the SMS, the system requests the switch 110 to change the presence of the corresponding phone number, and the switch 110 requests the PLT 120 to change the presence according to the corresponding setting. After checking the presence of the number, if the condition is met, the presence of the wired or wireless telephone (300, 310) to change the presence of the call routing for the lifetime number. Thereafter, the call may be preferentially received by the wired / wireless telephones 300 and 310 subscribed to the lifetime number.

Sixth, a method of changing a presence through a dedicated IP phone is a method of changing the presence of a user by selecting the operation of the 'call routing' function of an IP phone capable of setting a presence.

Specifically, first, when the user sets the 'call routing' function in the dedicated IP phone, the IP phone may be pre-routed to the switchboard 110 so that call routing for the lifetime number can be routed to the wired or wireless telephones 300 and 310. Since the request for a change of the call can be received preferentially to the wired or wireless telephone (300, 310) subscribed for the lifetime number.

Seventh, the presence is changed by using a dedicated mobile terminal having a call routing function.

Specifically, when a user sets a presence for a specific telephone number using a mobile terminal having a call routing function, the exchange 100 requests the PLT 120 to change the presence according to the corresponding setting. After confirming the presence of the telephone number, 120 changes the presence of the call to the desired device if the condition is met. The call can then be preferentially received by the desired device for the lifetime number.

Eighth, the way to change the presence via the Web.

Specifically, after the user accesses the web providing the presence change function and completes the authentication process, when the presence change is determined to change the presence of a specific phone number, the web system changes the setting to the exchange 110. Request, the exchange 110 requests the PLT 120 to change the presence according to the corresponding setting, and the PLT 120 checks the presence of the corresponding phone number and, if the condition is met, the wired / wireless telephone 300 that is subscribed to. 310, the presence is changed to enable call routing preferentially. Thereafter, the call may be preferentially received by the wired / wireless telephones 300 and 310 subscribed to the lifetime number.

Although the preferred embodiment of the present invention has been described in detail above, the present invention is not limited thereto, and various other changes and modifications are possible.

According to the present invention, by using the Internet phone number as a lifetime number can increase the utilization of the Internet phone, as a result, the call charges of the subscriber is reduced.

In addition, the call connection rate is improved by routing the call with a lifetime number to a telephone terminal that can be used by a user based on the presence of the present invention, thereby providing a high quality lifetime number service.
