Description

This application is a National Stage Entry of PCT/JP2012/057401 filed Mar. 22, 2012, which claims priority from Japanese Patent Application 2011-159894 filed Jul. 21, 2011, the contents of all of which are incorporated herein by reference, in their entirety.


TECHNICAL FIELD

The present invention relates to a telephone switch, a call pick-up method therefor, a call pick-up program therefor, and a telephone system, and in particular to a telephone switch in which an incoming call to an extension telephone is picked up from a mobile terminal, a call pick-up method therefor, a call pick-up program therefor, and a telephone system.


BACKGROUND ART

In general, as regards telephone switches such as PBXs (Private Branch eXchanges) accommodating a plurality of extension telephone sets and key telephone devices, the function of call pick-up is known. When there is an incoming call to an extension telephone set, the function of call pick-up makes it possible to give a response by deputy from another extension telephone set that is not called.


In a kind of this call pick-up function, an incoming call to an extension telephone set is picked up by dialing a special service code from another extension telephone set belonging to the same call pick-up group which is previously set. In another kind of the call pick-up function, an incoming call to an extension telephone set is picked up by dialing a special service code and a group number of a call pick-up group to which the called extension telephone set belongs, from another extension telephone set belonging to another call pick-up group. In addition, in another kind of the call pick-up function, an incoming call to an extension telephone set is picked up by dialing a special service code and an extension number of the called extension telephone set from another extension telephone set regardless of the call pick-up group. In this way, there are various kinds in the call pick-up function.


On the other hand, in a known system using a telephone switch in recent years, linking between fixed telephones and mobile telephones (hereafter referred to as “FMC linking”) such as, for example, an operation of calling a mobile telephone of an employee who is out with an extension number is conducted by using a technique of FMC (Fixed Mobile Convergence) which merges fixed telephones and mobile telephones.


In case of employees who are out of the enterprise in many hours such as employees in a business department in enterprises introducing such a telephone switch, it is conceivable that a fixed telephone is not provided on a desk of the employee and the employee uses a mobile terminal (hereafter referred to as “FMC linking terminal” for convenience) such as a mobile telephone capable of conducting FMC linking with a telephone switch not only outside the enterprise but also within the enterprise.


In a case where an employee who possesses only an FMC linking terminal picks up an incoming call in the system at that time, it is considered that the employee picks up the call from a fixed telephone of another employee because it is impossible to pick up the call from the FMC linking terminal. This is inconvenient in operation.


In connection with this, PTL 1 states that extension numbers and IP addresses of portable IP telephone sets are recorded in an extension number management table in an IP extension telephone system including portable IP (Internet Protocol) telephone sets such as mobile terminals coping with wireless LAN (Local Area Network). In addition, PTL 1 states that extension numbers are recorded in association with groups corresponding to segments of IP addresses, in this IP extension telephone system. According to this, it is said that portable IP telephone sets can be included in call pick-up groups and an incoming call in the IP extension telephone system can be picked up from a portable IP telephone set.

DESCRIPTION OF EMBODIMENTS

Hereafter, embodiments of a telephone switch and a call pick-up method therefor according to the present invention will be described in detail with reference to the drawings.


With reference to FIG. 1, a telephone system using a telephone switch according to the present embodiment includes a telephone network 1 used for communication of terminals, a telephone switch 2, a fixed telephone set 32, and an FMC linking terminal 31. The telephone network 1 includes a mobile telephone corporation network 11 and an IP telephone network 12. The telephone switch 2 is connected to the telephone network 1, and operates under program control. The fixed telephone set 32 is connected to the telephone switch 2. The FMC linking terminal 31 exists in the same premise as the fixed telephone set 32 does.


The FMC linking terminal 31 is formed of a mobile terminal such as, for example, a mobile telephone set or a smart phone provided by a mobile telephone corporation, and connected to the telephone switch 2 via the telephone network 1 (the mobile telephone corporation network 11 and the IP telephone network 12). This FMC linking terminal 31 can conduct FMC linking with the telephone switch 2 connected thereto via an outside line. For example, the telephone switch 2 has a conversion table (not illustrated) or the like capable of converting a telephone number and an extension number of the FMC linking terminal 31 to each other. And the telephone switch 2 conducts operation such as conversion of an extension number that is input from the fixed telephone set 32 to a telephone number of the FMC linking terminal 31 by using the conversion table. No matter where the FMC linking terminal 31 is located, therefore, the FMC linking terminal 31 can be called from the fixed telephone set 32 by using the extension number. In addition, in the present embodiment, the FMC linking terminal 31 allows an operation for picking up an incoming call to the fixed telephone set 32 in the same premise 3 via an outside line (the telephone network 1).


The telephone switch 2 is, for example, a PBX (private branch exchange), a key telephone device, a key telephone system, or the like. Functionally, the telephone switch can accommodate a plurality of extension telephone sets (fixed telephone sets). The telephone switch 2 is formed of, for example, a computer (controller) including a CPU (Central Processing Unit) which operates under program control and a memory (ROM (Read Only Memory)/RAM (Random Access Memory) which stores the control program and various control data. The telephone switch 2 includes a port connected to the telephone network 1 and a port connected to the fixed telephone set 32. The telephone switch 2 connects the telephone network 1 and the fixed telephone set 32 to each other and connects the fixed telephone set 32 and another fixed telephone set to each other via the ports, and conducts operations such as incoming call processing.


In the present embodiment, the telephone switch 2 has a function of picking up an incoming call to the fixed telephone set 32 from the FMC linking terminal 31 via an outside line (the telephone network 1), besides a function of picking up an incoming call to the fixed telephone set 32 from another fixed telephone set 32 having no incoming call via an extension. This call pick-up function is implemented by processing operations in a dial conversion unit 21 and a call pick-up function unit 22.


The dial conversion unit 21 includes a receiving dial table 211 and a conversion table 213. Furthermore, the dial conversion unit 21 may include a conversion table 213 for converting data in the receiving dial table 211 to data in the conversion dial table 212. In the present embodiment, the dial conversion unit 21 can operate under program control in the telephone switch 2.


Dial data that is sent from the FMC linking terminal 31 when picking up an incoming call to the fixed telephone set 32 in the same premise 3 from the FMC linking terminal 31 and that can be received via an outside line (the telephone network 1) and can be used for call pick-up is registered in the receiving dial table 211. As this dial data, for example, dial data using a special service code to be used in call pick-up can be utilized.


A call pick-up number to be used in the telephone switch 2 when picking up an incoming call in the telephone switch 2 is registered in the conversion dial table 212. As this call pick-up number, for example, a call pick-up number using a special service code to be used in call pick-up can be utilized.


In a case where the method of picking up an incoming call to an extension telephone set by dialing a special service code from another extension telephone set belonging to the same call pick-up group which is previously set is adopted, the fixed telephone set 32 and the FMC linking terminal 31 are previously registered in the same call pick-up group. In addition to that, an extension number corresponding to the FMC linking terminal 31 is previously registered as a call pick-up number registered in the conversion dial table 212.


Also in a case where the method of picking up an incoming call to an extension telephone set by dialing a special service code and an extension number of the called extension telephone set from another extension telephone set is adopted, an extension number corresponding to the FMC linking terminal 31 is previously registered as a call pick-up number registered in the conversion dial table 212.


Operation in the present embodiment will now be described in detail with reference to FIG. 2 and FIG. 3.


First, as previous setting, dial data to be used in call pick-up are set in the receiving dial table 211 and the conversion dial table 212 in the dial conversion unit 21. In other words, dial data to be sent from the FMC linking terminal 31 when picking up an incoming call from the FMC linking terminal 31 is set in the receiving dial table 211 as described above. Furthermore, a call pick-up number to be used in the telephone switch 2 when picking up an incoming call in the telephone switch 2 is set in the conversion dial table 212. In addition, correspondence relations between data in the receiving dial table 211 and data in the conversion dial table 212 are set in the conversion table 213.


Then, it is supposed that the FMC linking terminal 31 and the fixed telephone set 32 are located in the same premise 3. Here, an incoming call arrives at the fixed telephone set 32 via the telephone switch 2 as shown in FIG. 2 (step S1), and calling (ringing) processing is conducted (step S2). In a state in which there is an incoming call to the fixed telephone set 32, an operation for picking up the incoming call from the FMC linking terminal 31, i.e., a dial depressing operation corresponding to dial data previously registered in the receiving dial table 211 is conducted. And the FMC linking terminal 31 sends the dial data (step S3).


In a case where the telephone switch 2 has received the dial data sent from the FMC linking terminal 31 via the telephone network 1 (the mobile telephone corporation network 11 and the IP telephone network 12), call pick-up processing is conducted in the dial conversion unit 2 (step S4). A flow of this processing is illustrated in FIG. 3.


As illustrated in FIG. 3, the telephone switch 2 receives the dial data sent from the FMC linking terminal 31 (step S11: YES). Subsequently, it is determined by processing in the dial conversion unit 21 whether the received dial data coincides with some dial data registered in the receiving dial table 211 (step S12). In a case where coincidence is found as a result of the determination at the step S12 (step S12: YES), the received dial data is converted to a call pick-up number registered in the conversion dial table 212 (step S13). At the time of the conversion, the conversion table 213 may be set to be referred to. And the call pick-up number is specified and the call pick-up function unit 22 included in the telephone switch 2 is started. The call pick-up function unit 22 associates a number of the fixed telephone set 32 with a call pick-up number of the FMC linking terminal 31 (the call pick-up function unit 22 may conduct the association previously). An incoming call to the fixed telephone set 32 is switched to an incoming call to the FMC linking terminal 31 by utilizing this association.


As a result, it becomes possible to pick up the incoming call to the fixed telephone set 32 from the FMC linking terminal 31 by conducting conversion to the call pick-up number used in the telephone switch 2 in the state in which there is the incoming call to the fixed telephone set 32 (step S5). At this time point, the ringing processing of the fixed telephone set 32 is also finished (step S6).


In a case where an incoming call arrives at the fixed telephone set 32 in the present embodiment, therefore, dial data already registered in the receiving dial table 211 in the dial conversion unit 21 is depressed at the FMC linking terminal 31. And the dial data is sent to the dial conversion unit 21 in the telephone switch 2 via the mobile telephone corporation network 11 and the IP telephone network 12, and the dial data is converted to the call pick-up number registered in the conversion dial table 212 by the dial conversion unit 21 in the telephone switch 2. In the present embodiment, therefore, it becomes possible to pick up an incoming call to the fixed telephone set 32 from the FMC linking terminal 31.


Furthermore, in the present embodiment, it becomes possible to pick up an incoming call to the fixed telephone set 32 in the same premise 3 via an outside line from the FMC linking terminal 31. In this case, an outside line is used. Since an outside line talk charge of the FMC linking terminal 31 includes only a fixed charge, however, a measured rate charge does not occur.


In addition, most employees in business departments are expected to work outside the corporations for many hours. In that case, it is considered that the employee does not have a fixed telephone set 32 on the own seat and mainly uses the FMC linking terminal 31 (mobile telephone). In this case, it becomes possible to pick up a call without using the fixed telephone set 32 of another person by utilizing the function of the call pick-up function and performing a call pick-up operation from the FMC linking terminal 31 owned by the employee when the employee has returned to the corporation.


In the present embodiment, the tables (the receiving dial table 211 and the conversion dial table 212) prepared in the telephone switch 2 are used from the FMC linking terminal 31 provided by a mobile telephone corporation as described heretofore. As a result, it is made possible in the present embodiment to pick up an incoming call in the telephone switch 2. In other words, in the present embodiment, the receiving dial table 211 and the conversion dial table 212 that make call pick-up from the FMC linking terminal 31 possible are created in the telephone switch 2. In a case where there is an incoming call in the telephone switch 2, call pick-up from the FMC linking terminal 31 becomes possible by depressing a preset dial.


In the present embodiment, therefore, the following effects can be brought about.


As a first effect, it becomes possible even for a worker who possesses only the FMC linking terminal 31 to pick up an incoming call in the system.


As a second effect, call pick-up becomes possible not at the fixed telephone set 32 but at the FMC linking terminal 31 and consequently movement after the call pick-up becomes possible.


As a third effect, the operation cost can be held down by using the FMC linking terminal 31 because a talk charge does not occur except a fixed charge for the FMC linking terminal 31.


In PTL 1 described above, an incoming call to a fixed telephone is picked up from a mobile terminal via an extension. In this case, an incoming call to an extension telephone set in the telephone switch cannot be picked up from a mobile terminal that conducts FMC linking. In the present embodiment, however, an incoming call to the fixed telephone set 32 in the telephone switch 2 can be picked up via an outside line by operating the FMC linking terminal 31, which is a mobile terminal (outside line terminal) conducting FMC linking with the telephone switch 2.


By the way, as another embodiment, it becomes possible to conduct call pick-up not only from the FMC linking terminal 31 but also from another mobile terminal such as a mobile telephone that does not conduct FMC linking with the telephone switch 2.


Furthermore, the above-described telephone switch can be implemented by using hardware, software, or a combination of them. A configuration using hardware, software, or a combination of them in this case is not especially restricted, but any form can be applied as long as the above-described function can be implemented.


Furthermore, “the above-described function can be implemented by using software” means “the above-described function can be implemented by a computer which reads and executes a program for causing the computer to execute the method.” The program is stored by using non-transitory computer readable media of various types and the program can be supplied to the computer. The non-transitory computer readable media include tangible storage media of various types. Examples of the non-transitory computer readable medium include a magnetic recording medium (for example, a flexible disk, magnetic tape, and a hard disk drive), a magneto-optical recording medium (for example, an optical magnetic disk), a CD-ROM (Read Only Memory), a CD-R, a CD-R/W, and a semiconductor memory (for example, a mask ROM, a PROM (Programmable ROM), an EPROM (Erasable PROM), a flash ROM, and a RAM (random access memory)). Furthermore, the program may be supplied to the computer by transitory computer readable media of various types. Examples of the transitory computer readable medium include an electric signal, an optical signal, and electromagnetic waves. The transitory computer readable medium can supply the program to the computer via a wire communication path such as an electric wire and an optical fiber, or a wireless communication path.


The present application is based upon Japanese Patent Application 2011-159894 (filed on Jul. 21, 2011), and claims priority in the treaty of Paris based on Japanese Patent Application 2011-159894. Contents disclosed in Japanese Patent Application 2011-159894 are claimed in the present specification by referring to Japanese Patent Application 2011-159894.
