Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone system, and more particularly to an exchange, a plurality of base stations forming a plurality of calling areas,
The present invention relates to a telephone system including a mobile station that wirelessly communicates with a plurality of wired terminals and a base station and has a pickup service function.

[0002]

2. Description of the Related Art A telephone system including a private branch exchange and a wired terminal connected to the private branch exchange has been widely used as a private branch telephone system. Further, recently, as a more advanced private telephone system, for example, a calling area formed by one or a plurality of base stations is provided for each radius of several tens of meters, and a mobile station such as a cordless telephone is also used in addition to a wired terminal. A telephone system has also been proposed in which one or more base stations within a calling area are used for call processing by a mobile station.

On the other hand, as one of the services realized by a plurality of wired terminals, there is a pickup service. This service groups a plurality of terminals that are close in position on the premises (this group is called a pickup group), and when an incoming call to any terminal in the group is received, another terminal in the group uses a special number dial, Alternatively, it is possible to respond by a service request such as pressing a function key.

Further, by assigning a number to a pickup group, dialing a special number or pressing a function key and then dialing a group number, a group pickup service capable of answering an incoming call other than its own group is also realized. There is.

In the pickup service and the group pickup service, since the pickup group is formed corresponding to the terminals, not only wired terminals but also mobile stations can be accommodated in the pickup group.

However, when the mobile station is accommodated in the pickup group, the mobile station can freely move its location.
If the mobile station erroneously makes a request for a pickup service while moving, there is a possibility that it may answer an incoming call to a wired terminal in the pickup group to which the mobile station belongs at the destination. This groups multiple terminals that are close in position, and when a terminal that receives an incoming call cannot respond due to the absence of the called party, nearby terminals in the same pickup group proxy-reply to the incoming call,
It is not preferable from the original purpose of the pickup service of notifying the caller that the callee is absent and listening to the business. In other words, when the mobile station is located far away from the wired terminal in the pickup group to which the mobile station belongs, it is preferable that the mobile station cannot respond to the incoming call to the wired terminal in the pickup group. I can say.

Further, it is desirable that the mobile station be able to proxy-reply to an incoming call to a nearby wired terminal at the destination. For this purpose, the above-mentioned group pickup service may be used so that the mobile station can respond to the incoming call to the wired terminal belonging to the pickup group at the destination. However, for this purpose, the mobile station operator remembers the group numbers of many pickup groups,
You need to dial it. Therefore, in the case of a mobile station, a larger number of group numbers must be remembered as compared with the case of a wired terminal in which it is sufficient to remember the group number of a pickup group close to its own group.

[0008]

As described above, in the conventional pickup service, when picking up a mobile station, the mobile station can freely move its location.
There is a problem that the mobile station may erroneously respond to an incoming call to a wired terminal in the pickup group to which the mobile station belongs at the destination due to an erroneous operation while the mobile station is moving.

Furthermore, in order for the mobile station to respond to an incoming call to a wired terminal belonging to a pickup group near the destination by the group pickup service at the destination, the operator of the mobile station has a group number of a large number of pickup groups. There was also the problem of having to remember.

The present invention has been made in order to solve the above-mentioned problems of the conventional pickup service. A mobile station can respond to an incoming call to a nearby wired terminal regardless of its location, and it is An object of the present invention is to provide a telephone system which does not accidentally answer an incoming call to a wired terminal that is far away at a destination.

[0011]

In order to solve the above problems, the present invention provides a plurality of wired terminals, a mobile station, a plurality of base stations that wirelessly communicate with the mobile stations, a wired terminal and a base station. In a telephone system having an exchange to be exchange-connected and forming a plurality of calling areas by a plurality of base stations, a storage unit that stores a correspondence relationship between the calling area and a wired terminal installed in the calling area, When a service request is issued from the mobile station, the storage means is searched to identify the wired terminal existing in the calling area in which the mobile station is located, and when there is an incoming call to the wired terminal, the incoming call is identified. It is characterized in that the exchange has control means for controlling connection to the mobile station.

More specifically, the control means, more specifically, a calling area identifying means for identifying a calling area in which the mobile station is located when a service request is issued from the mobile station, and an identification by the calling area identifying means. A wired terminal identifying means for identifying a wired terminal existing in the designated calling area by searching a storage means, and an incoming call determining means for determining whether or not there is an incoming call to the wired terminal identified by the wired terminal identifying means. And an incoming call connection control means for controlling the incoming call to connect to the mobile station when the incoming call decision means decides that there is the incoming call.

Further, when the wired terminal existing in the calling area identified by the calling area identifying means is not identified by the wired terminal identifying means and when the incoming call determining means determines that there is no incoming call, a service request is issued. A service request refusal notifying means for making a service request refusal notification to the generated mobile station may be further provided.

Further, the wired terminals in each calling area may be divided into a plurality of groups, and the storage means may store the correspondence between the calling area and the group of wired terminals installed in the calling area.

[0015]

As described above, the telephone system of the present invention is provided with the storage means for storing the correspondence relationship between the calling area and the wired terminal or the group of a plurality of wired terminals in the calling area,
When a service request is issued from the mobile station, a wired terminal existing in the calling area in which the mobile station is located is identified by searching this storage means, and if there is an incoming call to this wired terminal, The incoming call is connected to the mobile station and the mobile station makes a proxy response.

Therefore, the mobile station can respond only to an incoming call to a wired terminal existing in the calling area in which the mobile station is currently located, that is, an adjacent wired terminal regardless of the location of the mobile station. As a result, there will be no accidental response to an incoming call to a wired terminal at a remote location at the destination.

Further, unlike the method in which the mobile station responds to an incoming call to a wired terminal belonging to a pickup group near the destination by the group pickup service, the operator of the mobile station needs to remember the group numbers of many pickup groups. Instead, it is only necessary to perform a simple pickup service request operation such as pressing a special number dial or a function key.

[0018]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows the configuration of a telephone system according to an embodiment of the present invention. In this telephone system, a plurality of base stations 2a to 2d and a plurality of wired terminals 3a to 3f are connected to a PBX (Private Branch Exchange) 1. The PBX 1 connects the base stations 2a to 2d and the wired terminals 3a to 3f by exchange. The base stations 2a to 2d form a plurality of calling areas 4a to 4b which are wireless zones. That is, in this example, the calling area 4a is formed by the base stations 2a to 2b, and the calling area 4b is formed by the base stations 2c to 2d. The mobile station 5 is, for example, a cordless telephone, and communicates with the wired terminals 3a to 3f and other mobile stations via any of the plurality of base stations 2a to 2d.

The wired terminals 3a to 3c constitute a pickup group 6a, and the wired terminals 3d to 3f constitute a pickup group 6b. These pickup groups 6a to 6b are assigned to the calling areas 4a to 4b, respectively. There is. In the conversion table 7 in the PBX 1, the numbers of the calling areas 4a to 4b and the wired terminal 3a are stored.
Correspondences with numbers (identification information) of 3f are stored as shown in FIG.

When the mobile station 5 issues a service request for a pick-up service, the control unit 8 in the PBX 1 searches the conversion table 7 for a wired terminal existing in the calling area in which the mobile station 5 is located. This is for identifying and controlling the connection of the incoming call to the mobile station 5 when there is an incoming call to the wired terminal, and is configured as shown in FIG. 3, for example. The control unit 8 includes a calling area identification unit 11,
It includes a wired terminal identification unit 12, an incoming call identification unit 13, an incoming call connection control unit 14, and a service request refusal notification unit 15.
The functions and configurations of these respective parts are as follows.

The calling area identifying unit 11 identifies the calling area 4i (i = a, b) in which the mobile station 5 is located when a service request is issued from the mobile station 5. Specifically, for example, the calling area identification unit 11 includes a table indicating the correspondence between the calling areas and the base stations, and the table is displayed from the positions of the base stations 2a to 2d that have received the service request from the mobile station 5. The calling area 4i can be identified by referring to it.

The wired terminal identifying unit 12 searches the conversion table 7 by using the calling area number of the calling area 4i identified by the calling area identifying unit 11 as a key, and thus the wired terminal 3j (j = j = j) existing in the calling area 4i. a, b, c
Alternatively, it identifies d, e, f).

The incoming call determination unit 13 is a wired terminal identification unit 12
The presence or absence of an incoming call to the wired terminal 3j identified by is determined. When the incoming call determination unit 13 determines that there is an incoming call to the wired terminal 3j, the incoming call connection control unit 14 controls the PBX 1 to connect the incoming call to the mobile station 5.
This is done for the exchange switch part inside.

The service request refusal notifying unit 15 determines that the wired terminal existing in the calling area 4i identified by the calling area identifying unit 11 is not identified by the wired terminal identifying unit 12, that is, no wired terminal is present in the calling area 4i. In the case of installation and when the incoming call determination unit 13 determines that there is no incoming call to the wired terminal 3j, a service request rejection notification is issued by sending RT or the like to the mobile station 5 that generated the service request. Is.

The control unit 8 is specifically configured by using a CPU and realizes a pickup service process by software processing. The procedure of the pickup service processing in the control unit 8 will be described below with reference to the flowchart shown in FIG.

First, the owner of the mobile station 5 recognizes a ring tone to an arbitrary wired terminal and operates a predetermined special number dial for requesting a service for a pick-up service or a service request. A service request is generated from the mobile station 5 by pressing the function key (S1). However, this service request may be generated as a result of the owner of the mobile station 5 mistakenly operating a special number dial or a function key while moving.

When a service request is generated from the mobile station 5 in this way, the mobile station 5 that has generated the service request.
The calling area 4i in which is currently located is identified (S
2). In the example of FIG. 1, if the mobile station 5 issues a service request, the calling area 4b in which the mobile station 5 is located is identified as 4i.

Next, it is judged whether or not a wired terminal is installed in the identified calling area 4i (S3).
In this example, the identified calling area 4i is 4b, and it can be seen from the conversion table 7 shown in FIG. 2 that the wired terminals 3d, 3e, 3f are installed in the calling area 4b. It is determined to be installed, and the wired terminals are identified as 3d, 3e, 3f.

Next, when it is determined in step S3 that a wired terminal is installed in the calling area 4i, it is determined whether or not there is an incoming call to the identified wired terminal (S4).
In this example, if any one of the wired terminals 3d, 3e, 3f has an incoming call, it is determined that there is an incoming call. Then, when it is determined in step S4 that there is an incoming call to any of the wired terminals 3d, 3e, 3f, the exchange switch unit in the PBX 1 is controlled so as to connect the incoming call to the mobile station 5 (S5). . In this way, the pickup service in which the mobile station 5 makes a proxy response to an incoming call to the wired terminal is realized.

On the other hand, when it is determined in step S3 that no wired terminal is installed in the calling area 4i identified in step S2, and in step S4, the incoming call is received by any of the wired terminals 3d, 3e, 3f. If it is determined that there is no such request, the mobile station 5 is notified of the refusal of the service request (S6). This corresponds to, for example, the case where there is an incoming call to a wired terminal in a calling area other than the calling area 4i identified in step S2, that is, a wired terminal located far from the mobile station 5. Such a case corresponds to the case where the service request is issued due to the operator of the mobile station 5 performing an erroneous operation, and as described above, it is inappropriate to apply the pickup service, and thus the service request is not appropriate. It gives a refusal notice.

As described above, according to the present embodiment, the operator of the mobile station 5 performs a simple service request operation such as a special number dial or a function key depression, so that only an incoming call to a nearby wired terminal can be made. You can respond on behalf.

Next, another embodiment of the present invention will be described. FIG. 5 shows another method of setting the calling area. In the present embodiment, since the communication state is continued even when the mobile station 5 moves, and because of the nature of radio, the plurality of calling areas 4a to 4b are not completely independent as shown in FIG.
As shown in FIG. 5, the system is configured such that the plurality of calling areas 4A to 4D partially overlap each other. Further, since the incoming call to the wired terminal can be known from the outside of the calling area by the ring tone or the like, the extensions of the wired terminals in the calling areas 4A to 4D may be overlapped with each other. For example, in FIG. 5, the response to the incoming call to the wired terminal of extension 4000 is permitted only to the mobile station (not shown) requesting the service via the base station (not shown) in the calling area A. . On the other hand, the response to the incoming call to the wired terminal of extension No. 4001 assigned to the overlapping area of the calling areas 4A and 4B is the calling area 4A or the calling area 4B.
The mobile station requesting the service is permitted through any of the base stations.

FIG. 7 shows calling areas 4A to 4 in FIG.
The correspondence relationship between the D number and the extension number of the wired terminal corresponding thereto is shown, and this correspondence relationship is stored in the conversion table 7 of FIG. For example, when the mobile station 5 is in the calling area 4B in FIG.
It is possible to respond to incoming calls to the wired terminals 001, 4005, 4008, 4009. Further, when the mobile station 5 moves to the calling area 4D, the mobile station 5 uses the extension number 400
7,4009, 4010, 4012, 4013 can answer incoming calls to the wired terminals.

FIG. 6 is a block diagram showing the configuration of a telephone system according to still another embodiment of the present invention. The telephone system of this embodiment is basically the same as the embodiment of FIG. 1 except that the calling group is associated with the pickup group to which the wired terminal belongs.
Different from That is, in the example of FIG. 6, the calling area 4a is associated with the pickup group 9a, and the calling area 4b is associated with the pickup groups 9b to 9c. In this case, the conversion table 7 contains
As shown in, the correspondence between the numbers of the calling areas 4a-4b and the pickup groups 9a-9c is stored. Also in this embodiment, the basic configuration of the control unit 8 and the procedure of the pickup service processing are the same as those in the previous embodiment.

[0035]

As described above, in the telephone system of the present invention, the mobile station is provided with the storage means for storing the correspondence between the calling area and the wired terminal or the group of a plurality of wired terminals in the calling area. When a service request from the mobile station is generated, the storage means is searched to identify the wired terminal existing in the calling area in which the mobile station is located, and if there is an incoming call to this wired terminal, the incoming call is received. Is connected to the mobile station and the mobile station makes a proxy response.

Therefore, according to the present invention, the mobile station, regardless of its location, only responds to an incoming call to a wired terminal existing in the calling area in which the mobile station is currently located, that is, an adjacent wired terminal. be able to. This solves the problem of the conventional pickup service in which the mobile station erroneously answers an incoming call to a wired terminal located at a remote position due to an erroneous operation while moving.

Further, in the present invention, unlike the conventional method in which a mobile station responds to an incoming call to a wired terminal belonging to a pickup group near a destination by a group pickup service, the mobile station operator handles a large number of pickup groups. You don't have to remember the group number. That is, the mobile station can make a proxy response to an incoming call to a nearby wired terminal only by a simple service request generating operation such as a special number dial or pressing a function key.
