Description

  The present invention relates to a telephone, an exchange, and a control method thereof. The present invention particularly relates to a telephone set connected to a terminal, an exchange to which the telephone set is connected, and a control method thereof.

  In recent years, with the advancement of network technologies such as IP (Internet Protocol) telephones and wireless LAN (Local Area Network), in offices where employees work, the layout where seats are not fixed for each employee (hereinafter referred to as “free”) An increasing number of companies are introducing addresses.

  In offices where free addresses are introduced, employees are free to choose vacant seats in the office. For this reason, personal computers (personal computers, PCs) and telephones used exclusively for each employee cannot be fixedly installed in a specific seat. Therefore, in an office where a free address is introduced, a wireless LAN system is introduced and a smart device (multifunctional information processing terminal) such as a notebook PC or a smart phone (multifunctional mobile phone) having a wireless LAN interface is installed. Often distributed to employees. Smart devices are distributed to each employee so that employees can work using these devices even if the seats they work on are not fixed.

  In relation to the present invention, Patent Document 1 describes a telephone terminal having a function of logging in as a user dedicated terminal. Patent Document 2 describes a method of transferring a call with a mobile phone to an extension phone using a Bluetooth (registered trademark) connection. Patent Document 3 describes a configuration in which a mobile phone acquires an IP address from a DHCP (Dynamic Host Configuration Protocol) server.

JP 2007-123971 (paragraph [0013]) Japanese Patent Laying-Open No. 2005-197777 (paragraph [0048]) JP 2009-258916 A ([0033] paragraph)

  When a free address is installed in an office where a wireless LAN system or a private PHS system is not installed, the user needs to connect a telephone line or a LAN cable to the notebook PC before starting work. Also, when the user moves from office to office, the user needs to disconnect those cables. For this reason, there is a problem that the convenience of the user is low in an office in which such a wireless system is not introduced.

  In addition, in an office where a free address is introduced, in order for the user to operate the installed telephone as a dedicated extension telephone, the user must manually enter an ID (Identification) and password before starting work. You need to enter and log into the system. Furthermore, the user needs to perform a logout operation to register the absence at the extension telephone system at the end of the business. As described above, even in a case where an installed telephone is used as a personal extension telephone in an office where a free address is introduced, there is a problem that the convenience for the user is low.

  Hereinafter, wireless systems such as a wireless LAN and a private PHS system are collectively referred to as a “wireless access system”.

  On the other hand, in order to introduce a wireless access system, it is necessary to examine the installation position of an antenna for communicating with smart devices used by employees, and to actually measure the propagation state of radio waves in the office . The design of such a wireless system requires advanced technology, and the installation of an antenna also requires the wiring of cables inside and outside the building and work at high places. For this reason, the introduction of a wireless system requires a request from a specialized construction contractor, and there is a problem that time and cost are required.

  Further, when a telephone using a wireless LAN or a private PHS telephone is adopted as a telephone, it is necessary to distribute the telephone to all employees. In this case, even if the number of seats in the office is smaller than the number of employees, it is necessary to distribute the telephones to all employees. Therefore, the wireless access system has a problem that the cost of the telephones at the time of introduction is high.

  Further, even after the introduction of the wireless access system, there is a possibility that desired wireless communication quality may not be ensured depending on the location as a result of fluctuations in radio wave propagation due to, for example, a change in the position of office furniture. In such a case, it is necessary to consider re-measurement of radio wave propagation status, change of antenna position, or addition of antennas. That is, the wireless access system also has a problem that the burden for maintaining the system after starting operation is large.

  As described above, when a free address is introduced into an office, there are problems that user convenience is low, and that a burden is high when a network system is constructed and its operation is started.

Patent Documents 1-3 describe techniques related to telephone systems used in offices and homes. However, Patent Documents 1-3 disclose means for solving the problem that when a free address is introduced into an office, the convenience of the user is low and the burden of construction and maintenance of the network system is large. Absent.

(Description of operations of fixed telephone and IP-PBX)
FIG. 6 is a flowchart showing a processing procedure of the fixed telephone 102 after the fixed telephone 102 and the wireless terminal 103 are connected. FIG. 8 is a flowchart showing the processing procedure of the IP-PBX 101. The wireless communication system provided in the wireless interface for connecting the fixed telephone 102 and the wireless terminal 103 is not limited. For example, when the fixed telephone 102 and the wireless terminal 103 are provided with a Bluetooth interface, the fixed telephone 102 and the wireless terminal 103 are set to automatically connect when approaching a distance that allows wireless communication. Is possible. When the connection between the fixed telephone 102 and the wireless terminal 103 is completed, the flow of FIGS. 6 and 8 is started. 6 and 8, the case where the fixed telephone 102a and the wireless terminal 103a are connected will be described. However, the procedures in FIGS. 6 and 8 are the same when the fixed telephone 102b and the wireless terminal 103b are connected. The procedure of FIG. 6 may be executed by the control unit 1023 of the fixed telephone 102a. The procedure of FIG. 8 may be executed by the control unit 1013 of the IP-PBX 101.

  In FIG. 6, when the fixed telephone 102a is connected to the wireless terminal 103a, it acquires a unique ID from the wireless terminal 103a (S401). The fixed telephone 102a notifies the IP-PBX 101 of the acquired unique ID of the wireless terminal 103a (S402). Thereafter, the procedure of FIG. 8 described later is performed in the IP-PBX 101. After the procedure of FIG. 8 is completed, if the fixed telephone 102a can obtain the encrypted login information (that is, the login ID and password) from the IP-PBX 101 (S403: Yes), the fixed telephone 102a The converted login information is decrypted (S404). The fixed telephone 102a logs into the IP-PBX 101 using the decrypted information (S405), and the telephone function of the fixed telephone 102a is enabled. Here, the extension number corresponding to the unique ID of the wireless terminal 103a stored in the unique ID database 1012a is set as the extension number of the fixed telephone 102a. Thereafter, the wireless terminal 103a and the IP network 100 are connected, and frame transfer is started between them (S406). The fixed telephone 102 a connects the wireless terminal 103 a and the IP network 100 when the login to the IP-PBX 101 is successful. The fixed telephone 102a does not connect the wireless terminal 103a and the IP network 100 when the login is not successful.

  When frame transfer between the wireless terminal 103a and the IP network 100 is started, the wireless terminal 103a requests the DHCP server 104 to issue an IP address. The wireless terminal 103 a connects to the IP network 100 using the IP address assigned by the DHCP server 104. As a result, the wireless terminal 103a can communicate via the IP network 100. Since the IP address distribution procedure by the DHCP server is well known, detailed description thereof will be omitted.

  After step S406, the fixed telephone 102a monitors whether the wireless connection with the wireless terminal 103a is maintained (S409). If the wireless connection is maintained (S409: Yes), the login state is continued. To do. When the wireless connection between the fixed telephone 102a and the wireless terminal 103a is disconnected (S409: No), the fixed telephone 102a logs out from the IP-PBX 101 (S410), and this flow ends.

  On the other hand, in step S403, when the fixed telephone 102a cannot acquire at least one of the login ID and the password from the IP-PBX 101 (S403: No), the fixed telephone 102a notifies the outside of the connection impossible message (S407). ). The connection impossible message is a message indicating to the outside of the fixed telephone 102a that connection with the IP-PBX 101 is impossible.

  FIG. 7 is an example of a connection impossible message. The fixed telephone 102a includes a display, and when login information acquisition fails, the message shown in FIG. 7 may be displayed on the display. The fixed telephone 102a may notify the outside that the login information has failed to be acquired by voice or lamp.

  If the IP-PBX 101 determines that the connection with the fixed telephone 102a is impossible, the IP-PBX 101 transmits a connection impossible notification to the fixed telephone 102a. For example, when the login information corresponding to the unique ID notified from the fixed telephone 102 a is not found in the database 1012 of the IP-PBX 101, the fixed telephone 102 a receives a connection failure notification from the IP-PBX 101. Also when the fixed telephone set 102a receives the connection failure notification, the flow in FIG. 6 transits from step S403 to S407. If the fixed telephone 102a cannot connect to the IP-PBX 101, the fixed telephone 102a disconnects from the wireless terminal 103a (S408), and this flow ends.

  FIG. 8 is a flowchart showing the processing procedure of the IP-PBX 101. The flow in FIG. 8 is started when the fixed ID 102a notifies the IP-PBX 101 of the unique ID of the wireless terminal 103a, that is, when the login ID and password are inquired to the IP-PBX 101.

  When the IP-PBX 101 acquires the unique ID of the wireless terminal 103a from the fixed telephone 102a (S601), the IP-PBX 101 checks whether the acquired unique ID is registered in the unique ID database 1012a (S602). When the acquired unique ID is registered in the unique ID database 1012a (S602: Yes), the IP-PBX 101 acquires an extension number corresponding to the acquired unique ID from the unique ID database 1012a (S603). Then, the IP-PBX 101 acquires the login information of the fixed telephone 102a from the login information database 1012b using the extension number acquired in step S603 as a key (S604). The acquired login information is encrypted (S605). The IP-PBX 101 notifies the fixed telephone 102a of the encrypted login information (S606), and this flow ends. By encrypting the login information, the login information is securely notified to the fixed telephone 102 a on the IP network 100. The encryption procedure may be fixed in advance as the specification of the telephone system 1, or may be determined each time by negotiation between the IP-PBX 101 and the fixed telephone 102a.

  After step S606, when the fixed telephone 102a logs in using the login information notified in step S606, the exchange causes the fixed telephone 102a to function as a telephone having an extension number corresponding to the login information.

  In step S602, if the unique ID notified from the fixed telephone 102 is not registered in the unique ID database 1012a (S602: No), the IP-PBX 101 transmits a connection impossible notification to the fixed telephone 102a (S607). This flow ends. The connection failure notification is transmitted when the IP-PBX 101 determines that the connection with the fixed telephone 102a is impossible. In step S604, even if the login information of the fixed telephone 102a cannot be acquired from the login information database 1012b, the IP-PBX 101 may transmit a connection impossible notification to the fixed telephone 102a.

  In an office where a free address is introduced, when an employee who is a user of the telephone system 1 brings a wireless terminal 103 such as a notebook PC in a range where communication with the fixed telephone 102 is possible, the fixed telephone 102 and the wireless terminal 103 are wirelessly connected. Is done. The connection between the fixed telephone 102 and the wireless terminal 103 may be automatically performed without requiring the operation of an employee.

  In the above procedure, the fixed ID 102 is stored as the extension telephone dedicated to the employee by associating the unique ID of the wireless terminal carried by the employee with the extension telephone number of the employee in the unique ID database 1012a. It can be operated. The fixed telephone 102 automatically logs in to the IP-PBX 101. Further, the wireless terminal 103 can access the IP network 100 via the fixed telephone 102. When the wireless terminal 103 is a notebook PC, the employee can start work by connecting the notebook PC to the IP network 100 at the seat where the user is seated.

  In the telephone system 1 of the first embodiment, it is possible to connect the wireless terminal 103 to the IP network 100 simply by connecting the fixed telephone 102 to the IP network 100 without introducing a wireless access system. The fixed telephone 102 and the wireless terminal 103 are connected using short-range wireless communication.

  Compared with wireless access systems, the reach of radio waves is narrower in short-range wireless communication. For this reason, in the telephone system 1 of the first embodiment, unlike a general wireless access system, radio wave interference is unlikely to occur between the fixed telephone 102 and the wireless terminal 103 used in other seats. Therefore, the telephone system 1 does not need to measure the radio wave propagation state of the wireless terminal at the time of introduction. Further, in the telephone system 1, the fixed telephone 102 need only be installed in each seat, and it is not necessary to distribute a mobile phone to all employees in order to realize an extension telephone dedicated to employees.

  Further, the fixed telephone 102 is connected to the IP network 100 by wire. For this reason, even when the installation location of the fixed telephone 102 is changed, unlike the radio access system, communication quality is not deteriorated due to a change in the propagation state of radio waves, and the antenna position needs to be redesigned accordingly. Does not occur.

  As described above, the telephone system 1 according to the first embodiment has an effect that the burden of construction and maintenance of the network system is small.

  In addition, the telephone system 1 can easily manage the connection between the wireless terminal 103 and the fixed telephone 102 and the IP network 100. As a result, the burden on the user's operation is small and the convenience is high. The reason is that when the wireless terminal 103 and the fixed telephone 102 are connected, the fixed telephone acquires login information from the IP-PBX and automatically logs in to the IP-PBX. This is because the fixed telephone 102 automatically logs out from the IP-PBX 101 when the connection is disconnected.

  These effects of the telephone system 1 are particularly useful in an office where the seat where an employee works is not fixed due to the introduction of a free address. This is because, regardless of the seat used, employees can easily connect the mobile terminal 103 and the fixed telephone 102 installed in the seat as their own extension telephone. This is because it can be used.

In addition, the fixed telephone 102 has a function of automatically logging out from the IP-PBX 101, so that when there is an incoming call to an employee who has logged out due to reasons such as going out, the IP-PBX 101 has no such employee. It can be notified to the caller by voice guidance or electronic sound. On the other hand, when the telephone system 1 is not used, when an employee forgets the logout operation, the extension telephone of the employee remains ringing when an incoming call is received. In this case, the caller cannot determine whether the called employee is absent or temporarily away.
(Minimum configuration of the fixed telephone according to the first embodiment)
The minimum configuration of the fixed telephone 102 will be described below. The fixed telephone 102 includes a wireless interface 1021, an IP interface 1022, and a control unit 1023 shown in FIG.

  The wireless interface 1021 is a transmission / reception unit for communicating with the wireless terminal 103 by wireless communication. The IP interface 1022 is an IP interface circuit for connecting to the IP network 100. The control unit 1023 notifies the unique ID acquired from the wireless terminal 103 to the exchange (IP-PBX 101) connected to the IP network 100. Then, the control unit 1023 acquires the extension number and login information corresponding to the unique ID from the exchange, and logs in to the exchange using the acquired login information. Further, the control unit 1023 operates the fixed telephone 102 as a fixed telephone having the extension number notified from the exchange, and connects the wireless terminal 103 and the IP network 100.

The minimum configuration fixed telephone 102 having such a configuration and function also has an effect of reducing a burden for network construction and maintenance. The reason is that by installing the fixed telephone 102 in the seat, the mobile telephone need not be distributed to employees, and a wireless access system for connecting the wireless terminal 103 to the IP network 100 is not necessary. .
(Second Embodiment)
FIG. 9 is a diagram showing the configuration of the telephone system 2 according to the second embodiment of this invention. The telephone system 2 includes an IP network 700, an IP-PBX 701, a fixed telephone 702, a wireless terminal 703, an authentication server 704, and a DHCP server 705. The fixed telephone 702 is a generic name for the fixed telephones 702a and 702b, and the wireless terminal 703 is a generic name for the wireless terminals 703a and 703b.

  The IP-PBX 701 is an exchange for performing call control of the fixed telephone 702 connected via the IP network 700 and connection between the fixed telephone 702 and an external telephone network (public network or dedicated line). The IP-PBX 701 also manages the extension number and the outside line number of the fixed telephone 702. The IP network 700 is an in-house LAN or WAN.

  FIG. 10 is a block diagram illustrating a configuration of the IP-PBX 701 according to the second embodiment. In FIG. 10, the same reference numerals are given to the same components as those of the IP-PBX 101 shown in FIG. The IP-PBX 701 has a different database configuration compared to the IP-PBX 101 of the first embodiment. That is, the IP-PBX 701 includes the login information database 1012b illustrated in FIG. 2, but does not include the unique ID database 1012a. In the second embodiment, information corresponding to the content of the unique ID database 1012a is stored in the authentication server 704.

  The authentication server 704 is a directory server using, for example, LDAP (Lightweight Directory Access Protocol). The authentication server 704 includes a unique ID database in which the unique ID of the wireless terminal 703 and the extension number corresponding to the unique ID are stored. That is, the authentication server 704 includes a unique ID database in which the same content as the unique ID database 1012a illustrated in FIG. 4 is stored.

  The fixed telephone 702, the wireless terminal 703, and the DHCP server 705 have the same configurations and functions as the fixed telephone 102, the wireless terminal 103, and the DHCP server 104 described in the first embodiment, respectively. Therefore, detailed descriptions of the fixed telephone 702, the wireless terminal 703, and the DHCP server 705 are omitted.

  FIG. 11 is a flowchart illustrating a processing procedure of the IP-PBX 701 according to the second embodiment. FIG. 11 shows the subsequent processing procedure of the IP-PBX 701 when the fixed telephone 702a is notified of the unique ID of the wireless terminal 703a. The flow in FIG. 11 is started when the fixed telephone 702a notifies the unique ID of the wireless terminal 703a, that is, when the IP-PBX 701 is inquired about login information. The flow in FIG. 11 is the same when the fixed phone 702b is notified of the unique ID of the wireless terminal 703b.

  When the unique ID is notified from the fixed telephone 702a (S801), the IP-PBX 701 transfers the notified unique ID to the authentication server 704, and inquires of the authentication server 704 about the extension number corresponding to the notified unique ID ( S802). The authentication server 704 refers to the unique ID database provided in the authentication server, and returns an extension number corresponding to the unique ID transferred from the IP-PBX 701 to the IP-PBX 701. If the IP-PBX 701 can acquire the extension number from the authentication server 704 (S803: Yes), the fixed telephone 702a login information is acquired from the login information database 1012b using the acquired extension number as a key (S804). . The acquired login information is encrypted (S805). The IP-PBX 701 notifies the fixed telephone set 702a of the encrypted login information (S806), and this flow ends. The fixed telephone 702a operates as a telephone having the extension number acquired in step S803 by decrypting the encrypted login information notified from the IP-PBX 701 and logging into the IP-PBX 701.

  In step S803, when the extension number extraction has failed (S803: No), the IP-PBX 701 transmits a connection impossible notification to the fixed telephone 702a (S807), and this flow ends.

It is obvious that the telephone system 2 according to the second embodiment having such a configuration also has an effect that the burden of construction and maintenance of the network system is small like the telephone system 1 according to the first embodiment. Furthermore, in the telephone system 2 of the second embodiment, an authentication server having a unique ID database is installed outside the IP-PBX 701, so that the relationship between the unique ID corresponding to the wireless terminal and the extension number is changed to the IP-PBX 701. Can be managed by an independent device.
(Minimum configuration of IP-PBX in the second embodiment)
Note that the IP-PBX 701 of the second embodiment can also be expressed as an exchange having only the following components. The effects of the first and second embodiments can also be obtained by the following exchange. That is, the exchange includes an IP interface 1011, a login information database 1012 b, and a control unit 1013.

  The IP interface 1011 connects the exchange to the IP network 700. The login information database 1012b stores an extension number and login information corresponding to the extension number. The login information is information for logging in to the exchange and includes a login ID and a password. When the unique ID of the wireless terminal 103a connected to the fixed telephone 702a is notified from the fixed telephone 702a connected via the IP network 700, the control unit 1013 acquires the extension number corresponding to the notified unique ID. To do. Here, the extension number information corresponding to the unique ID does not need to be stored in the local exchange. For example, the control unit 1013 may inquire an external authentication server to acquire extension number information corresponding to the unique ID.

  Then, the control unit 1013 acquires login information corresponding to the acquired extension number from the login information database 1012b and notifies the fixed telephone 702a of the extension number and login information via the IP interface 1011. Thereafter, when there is a login by login information from the fixed telephone 702a, the exchange causes the fixed telephone 702a to function as a telephone having an extension number corresponding to the login information.

  The minimum configuration switch having such a configuration also has an effect that the burden of construction and maintenance of the network system is small. The reason is that since the wireless terminal is connected to the exchange via a fixed telephone, a wireless access system for connecting the wireless terminal to the exchange is not required.

  Although the present invention has been described with reference to the embodiments, the present invention is not limited to the above embodiments. Various changes that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention. For example, in the first and second embodiments, the case where there are two fixed telephones and two wireless terminals has been described. However, the number of fixed telephones and wireless terminals included in one telephone system is not limited to two.
