Abstract

PROBLEM TO BE SOLVED: To automatically assign a calling area to a master unit.SOLUTION: When the assignment request of area identification information for identifying calling areas (66, 67, 70) is received from a master unit (390), a control program allows a computer to perform processing to assign area identification information (0002) to the master unit (390) that has transmitted the received request. The area identification information is the information stored in a storage section (204) in association with addresses (YYY...Y.YYY) correlated with the address of the master unit that has transmitted the request on the basis of information that is stored in the storage section and assigned to the other master units (362-366, 382-386) and where addresses (YYY...Y.YYY in Fig.8) are associated with the area identification information (0002) and also on the basis of the address (YYY...Y.ZZZ) of the master unit that has transmitted the request.

Description

  The present invention relates to allocation of call area identification information.

  For example, in a wireless extension telephone system, a call area is allocated by a manager to a radio base station as a master unit that communicates with a mobile terminal as a slave unit.

  As a related technique, for example, there is a technique related to a private branch exchange system described in JP-A-2005-151478.

JP 2005-151478 A

  In an extension telephone system, since an administrator normally assigns a calling area to a parent device or a radio base station, there is a possibility that information such as a calling area number of the parent device is registered by mistake. However, the administrator may not be aware of the error until the master unit is used and notified of the fault, and it is not possible to receive an incoming call to the slave unit in the original calling area until the incorrect registration information is corrected. Possible situations and unnecessary traffic increase in the wrong area may occur.

  The inventors have recognized that it is desirable to automatically assign a calling area to a base unit or a radio base station.

  In one aspect, an object of the present invention is to enable a call area to be automatically assigned to a parent machine.

  According to one aspect of the present invention, when an area identification information assignment request for identifying a calling area is received from a parent device, an address and area identification information assigned to another parent device stored in the storage unit are obtained. Based on the associated information and the address of the parent device that transmitted the received request, the area identification information stored in the storage unit in association with the address correlated with the address of the parent device that transmitted the request A control program is provided for causing a computer to execute the process assigned to the transmitted parent device.

  According to one aspect of the present invention, a calling area can be automatically assigned to a parent device.

The objects and advantages of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims.
It is understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not intended to limit the invention.

  Non-limiting embodiments of the present invention will be described with reference to the drawings. In the drawings, similar components and elements have the same reference numerals.

  The private branch exchange connected to the intranet is connected between the extension handset or portable terminal and the fixed line telephone or portable terminal of the extension or external line via the master set or wireless base station (access point) connected on the intranet. A call path can be formed by setting a call. In addition, when a portable base unit is connected to a pre-registered intranet together with a calling area number, the handset can be connected to an extension or external fixed telephone or portable terminal via the base unit and the intranet and the private branch exchange. Can communicate over the telephone.

  Normally, an administrator (person) assigns an extension calling area number to the parent machine and registers the identification information and calling area number of the parent machine in the private branch exchange. For example, information such as the calling area number of the parent machine is incorrect. May be registered. For example, the same calling area number can be assigned to a parent device up to a specific upper limit number in the same calling area, but cannot be assigned to different calling areas. However, the administrator mistakenly assigns a call area number for which the number of parent machines has already reached the upper limit to another parent machine, or assigns a call area number used by a parent machine in a certain area. May be mistakenly assigned to the base unit used in the area. In this case, until the registration information is corrected, there may be a situation in which the incoming call to the slave unit in the original calling area is impossible or an unnecessary increase in traffic in the erroneous calling area. However, the administrator may not be aware of the error until the master is used and the user is notified of the failure.

  The inventors have recognized that it is desirable in a private branch exchange to automatically assign a call area to a base unit or a radio base station.

  An object of the embodiment is to enable a private branch exchange to automatically allocate a call area to a base unit or a radio base station. This object can be achieved by the embodiment.

Each of the base station apparatuses 322 to 326 and 362 to 366 can connect or cover up to a specific upper limit number (for example, 3) of mobile terminals.

  FIG. 4 shows an example of a schematic configuration of the private branch exchange 20.

  The private branch exchange 20 may be a computer and includes, for example, a switch unit 26 for setting a speech path, a processor 202, a storage unit 204, a communication unit 210, and an input / output interface (I / O) 220. An input unit 222 and a display unit 224 are connected to the input / output interface (I / O) 220. The private branch exchange 20 can be connected to an external drive 332.

  The processor 202 may be a CPU (Central Processing Unit) for a computer. The storage unit 204 includes a main storage device and an auxiliary storage device. The main storage device includes a storage device such as a semiconductor memory. The auxiliary storage device includes, for example, a hard disk drive (HDD) and / or a semiconductor memory such as a flash memory. The drive 332 may be for reading a recording medium 334 such as an optical disk or a magnetic disk in which software is recorded. The software may include, for example, an OS, a database management system (DBMS), an application program, and the like. The application program may include an application for calling area allocation.

  The processor 202 may be a dedicated processor implemented as an integrated circuit, for example. Further, the processor 202 may operate according to an application program stored in the storage unit 204. The application program may be stored in the recording medium 334, read from the recording medium 334 by the drive 332, and installed in the private branch exchange 20.

  The input unit 222 may include, for example, a plurality of keys, a touch pad, a numeric keypad, a keyboard, a touch panel, and / or a pointing device. The display unit 224 may be, for example, a liquid crystal display device or a liquid crystal display device with a touch panel.

  The processor 202 includes a control unit 2020, an application unit 2024, an area allocation unit 22, and other processing units 2050. The area allocation unit 22 includes a registration reception unit 2030, an area determination unit 2032, and a base station data setting unit 2034. The control unit 2020 may supply control signals to the application unit 2024, the area allocation unit 22, and the processing unit 2050 to control operations of these elements. The area allocation unit 22 may be formed as an area allocation control device separate from the processor 202.

  The storage unit 204 stores a base station data table. The base station data table includes registered base station identification information (ID or alias), assigned call area number or identification information, and IP address fields for each base station. Here, in the base station data table, either or both of the network address (network address part) and the subnet address (subnet address part) in the IP address may be stored instead of the IP address. . In the following description, information including a network address and a subnet address is referred to as a subnet address. The calling area number may be a value such as “00001”, “00002”, “0000A”, and “0000B”, for example.

  The registration receiving unit 2030 receives registration from a portable base station device 390 or the like newly connected to the partial networks 54 and 56 and the like. The area determination unit 2032 assigns a calling area number to the base station apparatus 390 or the like connected to the partial network 56 or the like. The base station data setting unit 2034 communicates with the base station device 390 connected to the partial network 56 and the like, and registers or sets the base station data of the base station device 390 and the like in the private branch exchange 20 (the storage unit 204).

  On the other hand, the temporary registration information of the portable base station device 390 that is not used is stored in the base station data table of the storage unit 204 of the private branch exchange 20 together with the temporary calling area number or the area unassigned information. Also good.

  FIG. 7 shows an example of the base station data table.

  The base station data table of FIG. 7 includes, for example, base station identification information “0000A” to “0000D”, paging area numbers or identification information “00001” to “00003”, IP addresses of active base station apparatuses. “XXX.XXX.XXX.XXX” and the like are registered. On the other hand, in the base station data table, base station identification information “000F1” to “000F3” and temporary call area numbers “90001” to “90003” of the base station apparatus (390) that is unused or inactive. May be temporarily registered. In this case, the unused base station apparatus base station data table IP address is blank. Instead of the temporary calling area number, information indicating that the calling area number is not assigned, or specific number or information indicating that the calling area number can be assigned may be used.

  On the other hand, when the mobile terminals 420 and 429 are located in the call area 64, they are detected and registered by the private branch exchange 20 via the base station apparatuses 322 to 326 and the like as being located in the call area 64.

  Next, a connection operation related to an incoming call to the mobile terminal 429 or an outgoing call from the mobile terminal 429 by the private branch exchange 20 will be described.

  It is assumed that the private branch exchange 20 detects an outgoing call or a call from a mobile terminal (420, 460) in the call area 64 or 66 with respect to the mobile terminal 429 in the call area 64, for example. In this case, the private branch exchange 20 transmits an incoming call or call signal to the mobile terminal 429 via the base station apparatuses 322 to 326 in the call area 64. The private branch exchange 20 operates in the same manner when detecting an incoming call to the mobile terminal 429 in the calling area 64 from a telephone or mobile terminal on the extension telephone network 5 or the public switched telephone network 7, for example. Next, when the mobile terminal 429 receives the incoming signal, the user of the mobile terminal 429 can perform a call setting operation on the mobile terminal 429. In response to the detection of the call setting operation via the base station device 326, the private branch exchange 20 performs a call between the calling-side telephone or portable terminal (420, 460) and the called-side portable terminal 429 via the base station device 326. Set up a call or channel in between.

  Further, for example, when the user of the mobile terminal 429 operates the mobile terminal 429 in the calling area 64 to make a call, the private branch exchange 20 transmits or receives the mobile terminal 429 via the base station device 326 in the calling area 64. A call signal is detected. In this case, the private branch exchange 20 is either directly or indirectly through another exchange, in the calling area 64 or 66 or on the extension telephone network 5 or the public switched telephone network 7. Send an incoming or ringing signal to the terminal. Next, in response to the detection of the incoming call operation at the incoming telephone or mobile terminal, the private branch exchange 20 calls between the outgoing mobile terminal 429 and the incoming telephone or mobile terminal via the base station device 326. Or set up a call path.

  Next, when the user connects the temporarily registered or unregistered base station device 390 to the partial network 56 of the movement destination, how the base station device 390 is registered and usable in the private branch exchange 20 It will be explained.

  The user of the portable terminal 429 receives the portable base station device 390 from the administrator, moves from the calling area 64 to a destination where the partial network 56 is installed or a business trip destination area, and establishes a base on the partial network 56. A station device 390 can be connected (dashed line). When the private branch exchange 20 detects the presence of the base station device 390 connected to the partial network 56, the private branch exchange 20 may assign the call area 66 assigned to the other base station device 362 or the like to the base station device 390. Good.

  FIG. 8 shows an example of the changed base station data table.

  In the private branch exchange 20, the area allocation unit 22 of the processor 202, for example, includes the subnet address “YYY.YYY.YYY” in the IP address of the base station identification information “000F1” of the base station device 390 connected to the partial network 56. Identify (dashed line). Next, for example, in the base station data table of FIG. 8, the area allocation unit 22 has an IP address that includes an address (dashed line) of the same subnet as the subnet address “YYY.YYY.YYY” of the base station device 390. The base station identification information “0000C” is identified. Next, the area allocation unit 22 determines that the number of base station apparatuses to which the calling area number “00002” of the base station identification information having the IP address including the address “YYY.YYY.YYY” of the same subnet is allocated is a specific upper limit. Check if the number has been reached. When the number of base station apparatuses to which the same calling area number “00002” is allocated does not reach a specific upper limit number (for example, 32), the area allocation unit 22 assigns the same calling area number “00002” to the base station apparatus 390. In addition to

  In this way, the mobile terminal 429 is connected to the mobile terminal in the call areas 66 and 64, the fixed telephone on the extension telephone network 5, or the public switched telephone network 7 via the base station device 390 in the call area 66. Telephone communication can be performed with the telephone.

  On the other hand, the subnet address of the IP address assigned to the partial network 56 or the base station device 390 is not registered in the private branch exchange 20 (storage unit 204), and may not be a target for call area assignment. is there. In this case, the area allocation unit 22 does not allocate a calling area to the base station apparatus 390. A partial network in a certain area may be out of the connection target of the base station apparatus.

  FIG. 2 shows another example of a schematic configuration of the extension system including the private branch exchange 20 and the group of wireless base station apparatuses 322 to 326 connected to the network 1 according to the embodiment. The network 1 includes partial networks 3, 54, 57, and the like. The partial networks 3, 54 and 57 are connected to each other via respective routers 15, 16 and 18.

  In FIG. 2, it is assumed that no wireless base station device is connected to the partial network 57 at first. Private branch exchange 20 and base station apparatuses 322 to 326 are connected in the same form as in FIG. The partial network 57 conforms to the Internet protocol (IP) and is connected to the partial network 3 via the router 18 or the like. In this case, it is assumed that the subnet address of the IP address assigned in the partial network 57 is registered in advance in the private branch exchange 20 (storage unit 204) and stored in the storage unit 204.

  It is assumed that the portable terminal 429 is initially registered in the private branch exchange 20 as being located in the calling area 64 via the base station device 326.

  Next, when the user connects a temporarily registered or unregistered base station device 390 to the partial network 57 of the moving destination, how the base station device 390 is registered and usable in the private branch exchange 20 It will be explained.

  After that, the user of the portable terminal 429 receives the portable base station device 390 from the administrator, moves from the calling area 64 to the destination where the partial network 57 is installed or the area where the partial network 57 is installed, and moves to the partial network 57. Can be connected to the base station apparatus 390 (broken line). When the private branch exchange 20 detects the presence of the base station apparatus 390 connected to the partial network 57, the private branch exchange 20 may allocate a new calling area 67 to the base station apparatus 390.

  In the private branch exchange 20, the area allocation unit 22 of the processor 202, for example, the address “YYY.YYY.ZZZ” of the IP address of the base station identification information “000F2” of the base station device 390 connected to the partial network 57 ( (Dashed line). Next, in the base station data table of FIG. 8, the area allocation unit 22 has an IP address including the subnet address (dashed line) that is the same as the subnet address “YYY.YYY.ZZZ” stored in the storage unit 204. Confirm that there is no base station identification information. Next, the area allocation unit 22 confirms in the storage unit 204 that the subnet address “YYY.YYY.ZZZ” is registered as the IP address subnet address in the available partial network 57. Next, the area allocation unit 22 allocates a new calling area number “00031” that is not in the base station data table of FIG. 8 to the base station identification information “000F2” of the base station apparatus 390.

  In this way, the portable terminal 429 is connected to the portable terminal in the calling area 64, the fixed telephone on the extension telephone network 5, or the telephone on the public switched telephone network 7 via the base station device 390 in the calling area 67. Telephone communication can be performed.

  FIG. 3 illustrates an extension telephone system including a private branch exchange 20, a group of wireless base station devices 322, 324, 326, and another group of wireless base station devices 362-366 connected to the network 1, according to an embodiment. Another example of the schematic configuration is shown. The partial networks 3, 54 and 56 are connected to each other via respective routers 15, 16, 19.

  3, the private branch exchange 20 and the base station apparatuses 322 to 326 are connected in the same form as in FIG. The partial network 58 conforms to the Internet protocol (IP) and is connected to the partial network 3 via the router 19 or the like. In this case, it is assumed that the subnet address of the IP address assigned in the partial network 58 is registered in advance in the private branch exchange 20 and stored in the storage unit 204. In this case, it is assumed that the number of base station apparatuses 362 to 366 reaches the upper limit of the number of base station apparatuses in one calling area.

  It is assumed that the portable terminal 429 is initially registered in the private branch exchange 20 as being located in the calling area 64 via the base station device 326.

  Next, when the user connects a temporarily registered or unregistered base station device 390 to the partial network 58 of the moving destination, how the base station device 390 is registered and usable in the private branch exchange 20 It will be explained.

  After that, the user of the portable terminal 429 receives the portable base station device 390 from the administrator, moves from the calling area 64 to the destination where the partial network 58 is installed or the area where the partial network 58 is installed, and the partial network 58 Can be connected to the base station apparatus 390 (broken line). When the private branch exchange 20 detects the presence of the base station apparatus 390 connected to the partial network 58, the private branch exchange 20 may allocate a new paging area 70 to the base station apparatus 390.

  For example, in FIG. 8, the area allocation unit 22 of the processor 202 uses a call area number “00032” different from other call area numbers for the base station identification information “000F3” of the portable base station device 390 registered in advance. ".

  In the private branch exchange 20, the area allocation unit 22 of the processor 202, for example, the address “YYY.YYY.YYY” of the subnet of the IP address of the base station identification information “000F3” of the base station device 390 connected to the partial network 58 ( (Dashed line). Next, in the base station data table of FIG. 8, the area allocating unit 22 selects another base having an IP address including the same subnet address (broken line) as the subnet address “YYY.YYY.YYY” of the base station device 390. The station identification information “0000C” is identified. Next, the area allocation unit 22 counts the number of base station apparatuses to which the calling area number “00002” of the other base station identification information “0000C” having the IP address including the address “YYY.YYY.YYY” of the same subnet is allocated. Check to see if a certain limit has been reached. In this case, it is assumed that the number of base station apparatuses to which the same calling area number “00002” is allocated has reached a specific upper limit number (for example, 32). Therefore, the area allocation unit 22 allocates a new calling area number “00032” that is not in the base station data table of FIG. 8 to the base station identification information “000F3” of the base station device 390.

  In this way, the portable terminal 429 is connected to the portable terminal in the calling area 64, the fixed telephone on the extension telephone network 5, or the telephone on the public switched telephone network 7 via the base station device 390 in the calling area 70. Telephone communication can be performed.

  Next, an example of a specific registration process of the base station device 390 connected to the partial networks 56 to 58 of the user's movement destination, which is executed in the area allocation unit 22, will be described.

  6A and 6B show an example of a flowchart for the process of determining the calling area number, which is executed by the processor 202 or its area allocation unit 22.

  When the base station device 390 is connected to the partial networks 56 to 58 shown in FIGS. 1 to 3, the base station device 390 can use the base station device 390 with respect to the private branch exchange 20 via the partial networks 56 to 58 and 3. Send a registration request to set up and register as a station. The registration request is a call area or call area number assignment request, and includes preregistered base station identification information of the base station device 390 and IP addresses assigned in the partial networks 56 to 58. The IP address includes a subnet address unique to each of the partial networks 56 to 58. The network addresses of the subnets of the partial networks 56 to 58 are registered in advance in the private branch exchange 20 by the administrator and stored in the storage unit 204.

  Referring to FIG. 6A, in step 502, the processor 202 (or its registration receiving unit 2030) receives a registration request via the partial network 3 from the base station device 390 connected to the partial networks 56 to 58. In step 504, the processor 202 (registration reception unit 2030) determines whether or not a registration request has been received. If it is determined that a registration request has been received, the procedure proceeds to step 506. If it is determined that the registration request has not been received, the procedure returns to step 502. Steps 502-504 are repeated until a registration request is received.

  In step 506, the processor 202 (or its area determination unit 2032) determines whether the base station identification information included in the received registration request is registered or stored in the base station data table (FIGS. 7 and 8). It is determined whether or not the base station identification information matches. If it is determined that the received base station identification information does not match the registered base station identification information (A), the procedure proceeds to step 530. On the other hand, if it is determined that the received base station identification information matches (B) the registered base station identification information to be automatically assigned, the procedure proceeds to step 508. If it is determined that the received base station identification information matches the registered base station identification information not subject to automatic allocation (C), the procedure proceeds to step 520 (FIG. 6B). The registered base station identification information that is not subject to automatic allocation includes, for example, base station identification information that is manually registered by an administrator using a conventional method.

  In step 508, the processor 202 (area determining unit 2032) determines whether the subnet address (network unit and subnet unit) of the IP address included in the received registration request is a target for automatic call area allocation. The subnet address of the IP address subject to automatic call area allocation is registered in advance in the private branch exchange 20 and stored in the storage unit 204. If it is determined that the subnet address of the IP address is not a target for automatic call area allocation, the procedure proceeds to step 530. On the other hand, if it is determined that the subnet address of the IP address is the target of automatic call area allocation, the procedure proceeds to step 512.

  In step 530, the processor 202 (area determination unit 2032) transmits a message rejecting the registration request back to the base station apparatus (390). Thereby, for example, when the base station apparatus (390) is erroneously connected to the partial network in the area where the use of the mobile terminal is prohibited, the use of the mobile terminal in the prohibited area can be prevented. The procedure then exits the routine of FIGS. 6A and 6B.

  In step 512, the processor 202 (area determining unit 2032) determines that the subnet address of the IP address of the base station device (390) is the subnet address of the IP address of the already registered base station device in the base station data table. Determine whether they match. Here, the registered base station apparatus is a base station apparatus to which a call area has already been assigned. If it is determined that the subnet address of the IP address matches that of the already registered base station device, the procedure proceeds to step 514. If it is determined that the subnet address of the IP address does not match that of the registered base station apparatus, the procedure proceeds to step 516.

  In step 514, the processor 202 (area determining unit 2032) determines whether or not the number of base station apparatuses in the already registered paging area is less than the maximum threshold value. The number of maximum thresholds may be 32, for example. If it is determined that the number of base station devices in the registered paging area is not less than the maximum threshold, that is, greater than or equal to the maximum threshold, the procedure proceeds to step 516. If it is determined that the number of base stations in the registered paging area is less than the maximum threshold, the procedure proceeds to step 518.

  In step 516, the processor 202 (area determining unit 2032) assigns an unused calling area number to the base station apparatus (390). Accordingly, the base station device (390) connected to the partial network (57) is connected to the base station device connected to another partial network, that is, another base station device having an IP address including an address of a different subnet. It is possible to prevent the call area number from being erroneously assigned. This also prevents the base station apparatus (390) connected to the partial network (58) from being assigned the same calling area number exceeding the upper limit number of base station apparatuses in the calling area (68). .

  In step 518, the processor 202 (area determining unit 2032) assigns the calling area number of another base station apparatus having an IP address including the address of the same subnet to the base station apparatus (390). As a result, the resources of the new calling area number are unnecessarily allocated to the base station device (390) having the IP address including the address of the same subnet as the IP address of the other base station device, and the resources of the calling area number are insufficient. Can be prevented.

  Referring to FIG. 6B, in step 520, the processor 202 (area determining unit 2032) transmits the assigned calling area number to the base station apparatus (390). Here, when the base station apparatus is manually registered by the administrator in the conventional method, the call area number assigned manually and stored in the base station data table in advance is transmitted. In response to this transmission, the base station apparatus (390) receives the calling area number, sets it as its own calling area number, and issues a setting request for setting its own base station data in the private branch exchange 20. It is transmitted to 20 area allocation units 22.

  In step 540, the processor 202 (or its base station data setting unit 2034) receives a base station data setting request from the base station apparatus (390). Next, the processor 202 (base station data setting unit 2034) stores the received base station data related to the base station apparatus (390), for example, unique information such as a calling area number and an IP address assigned to the base station apparatus 390. The data is stored in the base station data table (FIG. 8) of the unit 204.

  Thereafter, when it is detected that the base station device (390) is separated from the partial networks 56 to 58, the processor 202 (base station data setting unit 2034) determines the base station device from the base station data table (FIG. 8). The base station data (390) is deleted to return to the state before setting.

  As described above, according to the embodiment, in the private branch exchange, by automatically allocating a calling area to the base unit or the radio base station, it is possible to prevent erroneous registration of information such as the calling area number of the base unit. The For example, it is possible to prevent a call area number whose number of master units has already reached the upper limit from being erroneously assigned to another master unit. In addition, it is possible to prevent a call area number used in a parent device at a certain installation location from being erroneously assigned to a parent device used in a different installation location. As a result, it is possible to prevent a situation in which incoming calls to the slave unit in the original calling area become impossible, and to prevent a situation in which unnecessary traffic increase occurs in the wrong calling area.

  Further, according to the embodiment, a portable terminal can be used simply by taking a portable base station to an area where a base station is not installed and connecting to a partial network at that location. In addition, for this reason, the base station need not be set in advance with respect to the installation location, which is highly convenient for installing a new base station. Further, according to the embodiment, since the calling area identification information is determined in relation to the IP address of the partial network, it is not always necessary to set a new calling area for the new base station. Maintenance becomes easy.
