Description

[0001] METHOD FOR CALL TRANSFER SERVICE OF MIGRATION AND EXCHANGE SYSTEM FOR THE SAME [0002]

The present invention relates to a method of providing an incoming call connection service for an extension mobile subscriber in a private branch exchange, and more particularly, to a method for detecting the position of an extension subscriber and connecting an incoming call to an adjacent extension telephone.

In general, a private branch exchange (PBX) is a miniaturization of a telephone exchange, and is used mainly for establishing an internal telephone network in a general company using a large number of telephones or communication terminals. Private branch exchange (PSTN) based private branch exchange (PSTN) private branch exchange is common, but as the Internet is activated, private branch exchange (Pure IP private branch exchange, for example, IP-PBX) based on IP network which is packet network is being introduced. An IP-based PBX provides multimedia services such as voice or video communication VoIP services over an IP network using H.323 or SIP protocols.

The PBX refers to a telephone exchange, a facsimile, a computer, or the like, which provides various services such as a company or a school as one area and provides various services such as call transfer, call hold, Is used. The PBX performs multiple telephone exchange tasks in a single space and building. In addition, the PBX can be connected to a company or other local PBX to enable communication control between terminals, computers, and other information processing devices. A PBX can use a local area network by using a public telephone line without additional installation of a local area network. In addition, the PBX is connected to a CO switch and functions as a UE, and internally it is used as a PBX network switch. The PBX can eliminate the inconvenience and hassle of facilities such as expansion of the current line.

PBX has a call transfer function, so that the subscriber A of the private branch exchange is not a terminal (extension terminal A) linked to the extension A of his / her own, but a terminal interworking with another extension B subscribed to the private branch exchange The terminal B can switch the incoming call to the extension A and receive it, or if the telephone number C of the location where the user is located is set to the incoming call transfer function, C and receive it. An extension terminal for which the corresponding function is supported is required for the call forwarding function of the PBX. In the case of a terminal supporting the call forwarding function, there is an inconvenience in that an incoming call forwarding number must be entered before moving. If an incoming call forwarding number is not entered in advance, the call forwarding function will not be activated.

That is, in the extension terminal A that does not support the call forwarding function, the call is not established when the extension subscriber A is not present. When the extension terminal A supports the call forwarding function, the extension subscriber A must know the extension number B of the other extension terminal B to which the call is to be transferred, and input the extension number B to the extension terminal A in advance Should be. If the extension subscriber A does not move near the actual extension terminal B or moves again and is not in the vicinity of the extension terminal B even after activating the call forwarding function by taking the inconvenience, the extension subscriber A returns to the seat, Unless the switching function is canceled, all incoming calls to the extension number A are transmitted to the extension terminal B, which is troublesome for the subscriber of the extension terminal B.

1 is a view schematically showing a configuration of a communication system to which the present invention can be applied.

The communication system to which the present invention can be applied is not limited to a PBX system, a key telephone system using an ISDN (Integrated Services Digital Network) of a Primary Rate Interface (ISI) or a BRI (Basic Rate Interface) System and the like. Also, the present invention is applicable to a DECT system including an internal keying device for internal line communication between terminals and an IP key telephone device for allowing a terminal to connect to an external network such as ISDN and PSTN (Public Switched Telephone Network). In addition, it can be applied to a terminal using a SIP protocol, an IVR (Interactive Voice Response) device, a conference device, and the like.

The PBX server 20 shares a certain number of external telephone lines used in a company or the like with all the employees and transmits the internal subscribers (e.g., user terminals B, C, D (11-2, 12-1, 12 -2)) to automatically connect the phone to the telephone exchange server. The main purpose of using a PBX is to reduce the cost of assigning a regular phone line to all employees of the company. The PBX is owned by the general business entity, not the telephone company, and is operated under the responsibility of the entity. The user terminal A-1-1 is connected to the PBX server 20 via a communication network (telephone network (PSTN), mobile communication network, etc.) and is capable of telephone conversation with an internal subscriber of the PBX.

The presence server 21 can inform the current state information (such as during a call) between the internal subscribers of the PBX. The presence server 21 detects the incoming / outgoing state of the PBX internal subscriber and notifies the current state of the internal subscriber. For example, the internal subscribers can register the number of the internal subscribers (extension number) in the flow button of the key phone and check the status of the registered internal subscribers in real time. For example, the user terminal B (11-2) of the PBX internal subscriber can not only be the user terminal C (12-1, 12-2) of another internal subscriber but also the user terminal A -1). Here, the user terminals B, C and D (11-2, 12-1, and 12-2) are subscribers of the PBX system sharing the presence server 21 and may share presence information with each other. The user terminal A-1 is another system subscriber who does not share the presence server 21 and is connected to the PBX server 20 via a trunk line, such as a PSTN or the like via a wired line, a cellular phone, or an internet telephone, Although it is possible to communicate with the user terminals B, C, D (11-2, 12-1, 12-2) of the internal subscriber, they can not share the presence information with them.

The PBX server 20 is connected to a plurality of VoIP devices (not shown), a plurality of VoIP gateways (not shown), an intermediate server (not shown), a UC server 30, And provides a VoIP service using a SIP or H.323 protocol to terminals such as a general telephone (SLT), a digital key telephone (DKT), a Unified Communication Solution (UCS), a WiFi terminal, and a wired and wireless IP phone. In particular, the PBX server 20 manages each VoIP device / VoIP gateway, loads balance and incoming / outgoing signals, a device driver is provided for address translation of packets to route signaling and Real-time Transport Protocol (RTP) packets to the VoIP device / VoIP gateway.

Here, routing refers to a function that allows an IP packet to be transmitted to a destination. To allow a router to forward a packet to its destination, the router must know the route information (routing information) for that destination and forward the packet according to this information. Therefore, routers exchange route information with neighboring routers with route information for the destination, and the protocol that exchanges route information at this time is called a routing protocol. Routing Information Protocol (RIP), Open Shortest Path First (OSPF), and Border Gateway Protocol (BGP) are examples of typical routing protocols.

The PBX server 20 provides the load balancing service for the VoIP service based on the routing information obtained using the routing protocol and the topology information obtained by using the status information of each VoIP device / VoIP gateway. Basically, the PBX server 20 knows the status information (VoIP call information for VoIP service) of each VoIP device / VoIP gateway. This is because all the devices registered in the PBX server 20 including the VoIP device provide the VoIP service to the user by using the call function of the PBX server 20. Therefore, the PBX server 20 always manages the basic information and the current status information of each registered devices by using a protocol (for example, IPKTS protocol).

The PBX server 20 and the UC server 30 are connected for a unified communications (UC) solution associated with the KTS or the IP KTS and each user (user terminal D 12-2 of the UC client) , An instant messaging client program, etc.) to exchange messages and files with other users. In addition, the user terminal D (12-2), given the telephone number given by the PBX server 20, operates as a soft phone to enable telephone conversation while displaying status information of other UC clients, (11-1, 11-2, 12-1) of an external communication network (telephone network (PSTN), mobile communication network, wired and wireless Internet, etc.). At this time, when a call is received to the PBX server 20 via the external communication network, the UC server 30 processes the call according to the content (scenario) of the call processing table registered in the user terminal D 12-2. When a call is originated at the user terminal D 12-2, the UC server 30 processes the call according to the contents of the call processing table registered at the user terminal D 12-2.

The user terminal D 12-2 interlocks with the UC server 30 and can be connected to the UC server 30 through an instant messaging (IM), file sending, file sharing, web push, (voice call), imaging call, and the like.

In particular, in the present invention, the PBX server 20 supports 'missed call forwarding service'. The missed call forwarding service automatically detects the positional change of the user when the user moves out of the position (area) of the first terminal (e.g., the user terminal B (11-2) as a desk phone) To a second terminal (e.g., user terminal C (12-1) which is a desk phone) close to the user's current location. The second terminal may be not only a desk phone but also an IP telephone or a smart phone equipped with a soft phone.

For the missed call forwarding service, an ID card-type accessory to which an RFID tag 50 for automatically detecting the location information of the user is attached is needed. In the RFID tag 50, unique identification information (e.g., employee information such as a name and an employee number) that can identify an individual is recorded. Further, phone number information (e.g., an extension number) Information can be recorded.

In order to read individual RFID information (user identification information, etc.), a wireless tag recognizer (not shown) for wirelessly communicating with the RFID tag 50 to scan the RFID information and transmit the scanned data to the PBX server 20 via the network (40) is required.

The RFID tag 50 can be divided into a band of less than 135 kHz, a band of 13.56 MHz, a band of 433 MHz, a band of 860 to 960 MHz, and a band of 2.45 GHz, depending on a radio frequency band to be used. In order to increase the recognition distance, it is possible to use the 433 MHz band and the microwave of the ultra high frequency (UHF) and the 2.45 GHz band of the 860 to 960 MHz band. The RFID tag 50 may be classified into an active tag, a passive tag, and a semi-passive tag. For example, an active tag is used in the 433 MHz band and a passive tag is used in a relatively short distance (within 10 m for UHF and within 30 cm for microwave) in the 860-960 MHz band or 2.45 GHz band, , The active tag is used.

The wireless tag recognizer 40 receives and reads the information of the RFID tag 50 and transmits the read information to the PBX server 20 and is capable of one-to-one or one-to-many communication with the RFID tag 50.

The PBX server 20 basically maps and manages a telephone number, a user terminal, and user identification information to the call management DB 23, and controls the call / incoming call through the call server 22. For example, the user 1 is managed by mapping the extension number "1000 " and the user terminal B 11-2. The call server 22 sends a telephone call to the user terminal B 11-2 when the call is made to the extension number "1000" from the outside or inside (e.g., the user terminal A 11-1) ring 1, and user 1 recognizes the incoming call and receives a call. In order to perform the missed call forwarding service of the present invention, a position change of the user 1 is automatically detected and a call arriving at the first terminal (user terminal B 11-2) is referred to as a second terminal User terminal C (12-1)). In order to do this, the call management DB 23 must additionally manage the information of the mobile user 1. A more detailed description will be given later with reference to Fig. 3 and Fig.

According to the first embodiment of the present invention for the missed call forwarding service, as shown in FIG. 2, the wireless tag recognizers 41, 42, and 43 are connected to the user terminals B, C and D 11-2 and 12-1 , 12-2.

According to an embodiment, the radio tag recognizers 41, 42 and 43 are mounted on the user terminals B, C and D respectively 11-2, 12-1 and 12-2, and the user terminals B, C and D One-to-one correspondence to the RFID tags 50-1, 50-2, 50-2, 50-3, 50-2, 50-3, 50-2,

According to another embodiment, the radio tag recognizers 41, 42 and 43 are not mounted on the user terminals B, C and D respectively 11-2, 12-1 and 12-2, One-to-one correspondence to the user terminals B, C, and D (11-2, 12-1, 12-2) Thereby forming respective user terminal areas capable of communicating with the RFID tag 50.

The wireless tag recognizers 41, 42, and 43 corresponding one-to-one to the user terminals B, C, and D (11-2, 12-1, and 12-2) Or may coexist in the same space. The wireless tag recognizer 41 and the user terminal B 11-2 exist in a pair in the office A and the wireless tag recognizer 42 and the user terminal C 12-1 exist in a pair in the office B. have. The wireless tag recognizer 41 and the user terminal B 11-2 exist in a pair in a space of the office A and the wireless tag recognizer 42 and the user terminal C 12 -1) may be present in pairs.

The call management DB 23 according to the first embodiment of the present invention includes a unique identification number of the radio tag recognizers 41 to 43 forming the user terminal area and a unique identification number (ID No.) of the user 1 that has moved from the second user terminal area (e.g., the communication area of the user terminal C 11-2) to the second user terminal area (e.g., the communication area of the user terminal C 12-1).

3, the call management DB 23 stores identification information (ID No.), a user terminal telephone number (for example, the user 1 is an extension number "1000" A-1, B-1, and B-2), a tag identifier unique number (AP-A-1, AP- B-1, and AP-B-2), presence / absence information (e.g., "On" when the user is absent and "Off" For example, "T1" is displayed when the user 1 is detected at a new position after departing from an existing position).

3, the user 1 uses the T1 tag and the identification information (ID No.) thereof is "T1 ", the conversion number assigned to the user is the extension number" 1000 ", the extension number & The user terminal B 11-2 assigned to the user terminal B 11-2 is located in the office A-1 and the unique number of the wireless tag recognizer 41 assigned to the user terminal B 11-2 on a one-to-one basis is "AP- .

If the user 1 leaves the communication area of the user terminal B 11-2, the radio tag recognizer 41 informs the PBX server 20 that the user 1 is not in position, and the PBX server 20 performs call management The DB 23 updates the user 1 to the position of absence (i.e., displays the presence information of the user as "Off "). When the user 1 moves from the office A-1 to the office B-2, the wireless tag recognizer (unique number "AP-B-2") 42 of the office B-2 detects T1, The PBX server 20 informs the PBX server 20 that it has moved to the communication area of the terminal C 12-1 and the PBX server 20 moves from the call management DB 23 to the communication area of the user terminal C 12-1 And adds the identification information T1 of the user 1 to the information field (movement detection information) of the user 3. [

The call server 22 of the PBX server 20 inquires the call management DB 23 to inquire the user terminal A 11-1 of the extension number "1000" (Presence information is "off") within the region of the extension number "-1002 " 12-1), and converts the extension number "1000" to the extension number "1002".

4 is a flowchart illustrating an inbound call connection service method according to the first embodiment of the present invention.

The telephone number of the user 3 is mapped in the call management DB 23 and stored in the call management DB 23 and the user 1 is connected to the communication area of the user terminal C 12-1 The wireless tag recognizer 42 communicates with the RFID tag 50 of the user 1 to receive the identification information of the user 1 (S401) and transmits the identification information (ID No.) of the user 1 to the PBX server 20 do.

Then, the PBX server 20 detects the movement of the user 1 as confirming the existence of the user 1 in the communication area of the user terminal C (12-1) (S402). That is, it is detected that the user 1 has moved to the communication area of the user terminal C (12-1) out of the communication area of the user terminal B (11-2).

Upon detecting the movement of the user 1 (S403), the PBX server 20 updates the call management DB 23 by mapping the telephone number of the user 1 to the user terminal C12-1 (S404). Thereafter, when a call is received from the user terminal A 11-1 to the telephone number of the user 1 (S405), the call server 22 of the PBX server 20 transmits the presence information of the user 1 of the call management DB 23 It is checked whether the user 1 exists in the area of the user terminal B 11-2 (S406).

If the user 1 exists in the area of the user terminal B 11-2 (if the presence information is "on" and is not in the absence), the user terminal B 11-2 attempts an incoming call (S407).

On the other hand, if the user 1 does not exist in the area of the user terminal B 11-2 (the presence information is "off" and the user is absent), the call management DB 23 And the identification information of the user 1 that has moved to the communication area of the user terminal C (12-1) is in the information field (movement detection information) of the user 3, The call is transferred to the terminal C (12-1) of the user 3 (S408).

5 is a diagram illustrating a configuration of an exchange system for implementing an incoming call connection service according to a second embodiment of the present invention.

According to the second embodiment of the present invention for the missed call forwarding service, as shown in FIG. 5, the radio tag recognizer 40 is connected to the user terminals B, C and D (11-2, 12-1, 12-2 C, and D (11-2, 12-1, and 12-2) in a stand-alone manner instead of being mounted on the user terminals B, C, and D , 12-1, 12-2 to correspond to one-to-many (1; N) to form respective user terminal areas capable of communicating with the RFID tag 50.

A wireless tag recognizer 40 may be provided for each space (office), and a plurality of wireless tag recognizers 40 may exist in the same space.

The user terminals B, C, and D (11-2, 12-1, and 12-2) may exist in the same space or may exist in different spaces. That is, the wireless tag recognizer 40 can manage the user terminals B, C, and D (11-2, 12-1, and 12-2) one-to-many in the office A. In the office A, the first radio tag recognizer manages the user terminal B 11-2. In the separated office B, the second radio tag recognizer manages the user terminal C 12-1, the user terminal D 12-2 ).

Hereinafter, a user terminal B (11-2) exists in the office A and is managed by a separate wireless tag recognizer (not shown), and the user terminals C and D (12-1, 12-2) And is managed by the wireless tag recognizer 40. [

5, the call management DB 23 includes a unique identifier of the wireless tag recognizer 40 that forms a user terminal area for each user, (For example, the communication area of the user terminals C and D (12-1 and 12-2)) in the first user terminal area (for example, the communication area of the user terminal B 11-2) (Not shown) and the user terminal B 11-2 and the distance information between the radio tag recognizer 40 and the user terminals C and D (11-2) in addition to the identification information (ID No.) of one user 1, 12-1 and 12-2 and the wireless tag 50 of the user 1 moved to the second user terminal area (for example, the communication area of the user terminals C and D (12-1 and 12-2) And manages received signal strength information.

6, the call management DB 23 stores identification information (ID No.), a user terminal telephone number (for example, the user 1 is an extension number "1000" 1, B-1, and B-2) and the tag identifier unique numbers (AP-1-1, AP-B (For example, "On" when the user is not in the office and "Off" when not in the absence of the user) Information (for example, "T1" is displayed when the user 1 is detected at a new position after leaving the existing position), and the like.

Here, the identification information of the moved user 1 is updated in either the user 2 or the user 3, which is recorded based on the value obtained by converting the received signal strength information into distance.

Specifically, when one radio tag recognizer 40 manages at least two user terminals C, D (12-1, 12-2), the radio tag recognizer 40 and the user terminals C, D (12- 1 and 12-2 are stored in the call management DB 23 and the received signal strength information of the radio tag 50 of the user 1 is converted into a distance. For example, if the distance between the wireless tag recognizer 40 and the terminal is within 3 m and 30 to 70 dBm (RF sensitivity is' middle ') when the received signal strength of the wireless tag 50 is 70 dBm or more (RF sensitivity' It is assumed that the distance between the wireless tag recognizer 40 and the terminal is 10 m or more when the distance between the terminal 40 and the terminal is 3 to 10 m and 30 dBm (lower than RF sensitivity). Therefore, when the received signal strength is 70 dBm or more (RF sensitivity 'on'), based on the distance information between the radio tag recognizer 40 and the user terminals C and D (12-1 and 12-2) C (12-1) can be found. That is, the nearest user terminal C (12-1) is a terminal with RF sensitivity 'above'.

6, the user 1 has the user terminal B (11) assigned with the identification number (ID No.) of "T1", the telephone number assigned to the user 1 is the extension number "1000" -2 is located in the office A-1, and the unique number of the wireless tag recognizer (not shown) assigned to the user terminal B 11-2 is "AP-A-1".

If the user 1 leaves the communication area of the user terminal B 11-2, the wireless tag recognizer (not shown) notifies the PBX server 20 that the user 1 is not in position, and the PBX server 20 The call management DB 23 updates the user 1 to the seat absence (i.e., displays the presence information of the user 1 as "Off"). If the user 1 moves from the office A-1 to the office B-2, if the wireless tag recognizer 40 (unique number "AP-B-2 & D 12-1 and 12-2 to the PBX server 20 and the PBX server 20 notifies the call management DB 23 of the user terminals C and D 12-1 (12-1, 12-2) to the communication area of the user terminals C, D (12-1, 12-2). In this case, 1 to the information field of the user 2 or the user 3 according to the received signal strength information of the radio tag 50. For example, if the received signal strength is 70 dBm or more (RF sensitivity 'on'), the information is recorded in the information field (movement detection information) of the user 3.

The call server 22 of the PBX server 20 inquires the call management DB 23 to inquire the user terminal A 11-1 of the extension number "1000" (Presence information is "off") in the region of the extension number "1002 " 12-1), and converts the telephone number of the extension number "1000" to the extension number "1002" of the user terminal C (12-1) closest to the user 1.
