Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incoming call control system for a fixed telephone and a mobile handset of a cordless telephone exchange system.

With the spread of cordless telephones in recent years, cordless telephone exchange systems have come into wide use in offices, factories and the like. In a cordless telephone exchange system,
A fixed telephone, a base unit located in each zone, and a central line are connected to a switchboard by a wire, and the base unit in each zone communicates wirelessly with a mobile handset.

In such a cordless telephone exchange system, a user of a fixed telephone is often used in a form of holding a mobile handset at the same time. In this case, different telephone numbers are assigned to the fixed telephone and mobile unit,
When the user is in his / her seat, the fixed telephone is used to make and receive calls, and when the user leaves the seat, he / she carries the mobile device and registers the destination so that the mobile device can receive the call. However, it is desired to enable incoming calls to mobile handsets or fixed telephones without burdening users.

[0004]

2. Description of the Related Art FIG. 8 is an explanatory view of a conventional example. The cordless telephone exchange system is provided with a control unit 81 in a network 80 of exchanges, and is installed in a room where each department of a building such as a building in which an office contains a large number of fixed telephones 85 connected to the network 80 by wire is installed. Each is installed. In addition, on each floor of the building, a base unit 83 connected to an exchange by wire is provided, and each base unit 83 is a mobile handset (a portable cordless phone in a zone 82 where each wireless signal can reach). ) 84 and telephone communication can be performed wirelessly. In the example of FIG. 8, each zone 1 to n corresponds to the first floor to the nth floor of the building, and the base unit 83 is arranged in the zone on each floor.

The telephone number of the fixed telephone 85 placed on the desk is different from the telephone number of the mobile child device 84 used by the same person as the user of the fixed telephone 85. Holds the telephone number of the mobile handset in addition to the fixed telephone on the desk. If you are not at your desk, ask the caller to call your mobile phone number again,
Registration is made to receive the call forwarding service from the desk phone to the mobile handset, so that the destination mobile handset can receive the incoming call by the call forwarding.

To receive the conventional call forwarding service,
Before you move, dial the special number requesting the call forwarding registration to the exchange, and register the mobile station number and the zone number of the transfer destination as the transfer destination. As a result, the control unit 81 of the network 80 registers the number of the mobile handset and the zone number in the memory as the transfer destination of the fixed telephone number. After that, when a call arrives at the fixed telephone, it is checked whether the call forwarding registration is performed for the fixed telephone. If registered, the mobile telephone having the registered number is registered as the master unit 83 of the registered zone. Wirelessly from. A call can be made by receiving this call at the mobile handset carried by the user at the destination.

In this way, it becomes possible to receive an incoming call at the destination by the mobile child device held by the user. After registering this call forwarding, after the user returns to his seat,
In order to make outgoing and incoming calls using a desk phone, it is necessary to perform the same dial operation as for registration cancellation in order to cancel call forwarding registration.

[0008]

As described above, in the conventional cordless telephone exchange system, a user having two fixed telephones and a mobile handset moves an incoming call to the fixed telephone when he / she leaves his seat. If you want to receive it at your mobile terminal earlier, you have to perform the call forwarding registration operation in advance using a fixed telephone in order to receive the call forwarding service, which is troublesome.

There is also a problem that if the user forgets to cancel the call forwarding registration when returning to his / her seat, the user cannot receive the incoming call because the incoming call is received in the registered zone.

According to the present invention, when a user who uses a fixed telephone and a mobile handset does not perform any operation, an incoming call is sent to the destination mobile handset when the fixed telephone or the user carries the mobile handset. An object is to provide an incoming call control method of a cordless telephone exchange system capable of receiving an incoming call.

Is a mobile handset used by the user of the fixed telephone 4b, and 7a, 7b and 7c are zone a, zone b and zone c respectively, and 8 is a telephone line, ISDN compatible line, relay line, etc. It is an outside line.

A memory is provided in the control unit 2, and in the memory 3, 30 is a first table, 31 is a second table,
32 is a third table. The first table 30 stores fixed telephone numbers and mobile handset numbers used by users of the fixed telephones in association with each other, and whether or not to receive each service provided to the fixed telephones. An area for setting the value is provided. The second table 31 stores the mobile unit number, the home zone of the mobile unit (the zone where the corresponding fixed telephone exists), and the current zone (including the destination). In addition, the third table 32 stores information on callers who are allowed or rejected by the fixed telephone user.

The mobile table corresponding to the fixed telephone number is registered in advance in the first table 30 provided in the memory 3 of the control unit 2, and the mobile station corresponding to the mobile station number in the second table 31 is registered. The number of its own zone (home zone that covers the position where the user is normally) is registered in advance. When the user of the mobile slave device moves to another zone while holding the mobile slave device, the destination zone is registered by the conventional technique. That is, when an inquiry signal is generated from the base unit corresponding to a zone, a response is returned from the mobile unit within the zone, and the zone in which the mobile unit exists is detected and automatically registered, or the mobile unit is registered. When a user of the machine performs a position registration operation, a signal is generated and the master machine in the zone detects the signal, and the registration is similarly performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 2 is a processing flow of a basic embodiment according to the present invention, which is executed by a control unit (2 in FIG. 1) of a cordless telephone exchange system. FIG. 3 shows an example of arrangement of fixed telephones and mobile handsets corresponding to zones, and FIG. 4 is a specific example of a table referred to in the processing flow of FIG.

First, referring to FIGS. 3 and 4,
A fixed telephone 11 (telephone number 2100) accommodated in the network 10 is paired with a mobile child device 12 (telephone number 3100). That is, the mobile child device 12 is exclusively used by the user of the fixed telephone 11. In this case, in FIG. Corresponding table of fixed telephones and mobile handsets shown in
(Corresponding to table 30). If there is no mobile device corresponding to the fixed telephone as in the example of the telephone number "2101", it is displayed that it does not exist (in this example, "0" is displayed).

Since the fixed telephone 11 is located in the zone 1, the own zone (home zone) of the mobile child device 12 is the zone 1 and the parent device 13 is placed in the zone 1. FIG. 3 shows a state in which the user holding the mobile child device 12 has moved to the zone 3 as indicated by the dotted line. In the state where the mobile slave unit 12 has moved in this way, the current position of the mobile slave unit 12 is registered by the conventional position registration technique. In this case, as shown in FIG. In the accommodation zone table (corresponding to the second table 31 in FIG. 1) of the mobile child device shown in FIG. 1, “1” is set in the home zone and “3” is set in the current zone in correspondence with the mobile child device number. .

The processing flow of FIG. 2 will be described with reference to FIGS. When an incoming call to a fixed telephone occurs, is there a pair of mobile handsets? The table is determined (S1 in FIG. 2). At this time, if the destination telephone number is “2101”, there is no pair of mobile handsets, so the incoming call is immediately made to the corresponding fixed telephone (FIG. 2). S3). As in the case where the telephone number of the called party is "2100", there is a pair of mobile slaves based on the fixed telephone / mobile slave correspondence table, and the telephone number of the mobile slave is identified. In this case, is the mobile child device in its own zone (home zone)? The determination is made by referring to the accommodation zone table of the mobile child device as shown in (2) in FIG. If the current zone of the mobile handset matches with its own zone (home zone) according to this table, the incoming call is made to the fixed telephone. If it is not the own zone, the mobile handset located in the destination zone is called. (S4 in FIG. 2). At this time, outgoing and incoming calls are restricted to a pair of fixed telephones.

The control of the incoming call to the fixed telephone or the mobile handset is completed by the above S4, but as an additional service process for the user, the ringer rings and the ringer rings within a certain time as an additional service processing to the user. Determine if a response has been received (S in FIG. 2)
5) If there is no response, the mobile handset existing in the home zone can be controlled to receive the call. If an incoming call to a fixed telephone is answered within a certain period of time, the call becomes active.

The fixed response delay time (denoted by T), which is the criterion for the determination in S5, can be changed by a maintenance / operation command of the cordless telephone exchange system.
5 and 6 are processing flows (No. 1) and (No. 2) of the embodiment for providing a plurality of selectable services. FIG. 7 shows the tables referred to in the processing flows of FIGS. See also the table.

Here, in FIG. A in FIG. Data necessary for providing a plurality of services are correspondingly registered in the fixed telephone / mobile terminal correspondence table shown in (1), and the contents of each data will be described in the processing of each service described later. B. of FIG. Indicates whether or not to allow or deny transfer from a fixed telephone to a mobile handset for each caller.
(Corresponding to table 32).

In FIG. 5, when an incoming call request is made to the fixed telephone, the fixed telephone determines whether or not the incoming call is rejected (S1 in FIG. 5). This determination is based on A. Refer to the "Call restriction" column corresponding to the telephone number of the fixed telephone in the table shown in FIG. For this incoming call restriction information, the user dials a special number "Call Rejection Service Number" from the fixed telephone or mobile handset to the cordless telephone exchange, or the fixed telephone is provided with a "Call Rejection" registration button in advance. "Reject call" by pressing the registration button
By sending a request to the system to register. By registration, A. of FIG. A flag (“1”) is set in the “incoming call restriction” column corresponding to the telephone number of the fixed telephone that made the request in the table shown in FIG.

In S1 of FIG. 5, A.A of FIG. If the "restrict incoming call" flag is set by referring to the table in Table 2, the control unit restricts incoming calls to both terminals (fixed telephone and mobile handset in pair), and the caller cannot receive the call. If the tone is supplied (S2 in FIG. 5) and it is not set, is there a mobile handset paired with the fixed telephone? Is determined (S3 in FIG. 5), and if there is not, the process proceeds to S14 in FIG. 6 and the incoming call is made to the fixed telephone. If there is a pair of mobile handsets, it is identified by referring to the table (B. in FIG. 4) whether the mobile handsets are in its own zone, and if it is in its own zone, an incoming call is made to the fixed telephone (Fig. 5 S6, FIG.
Same as S14).

If it is determined in S4 of FIG. 5 that the mobile station is not in the own zone, it is possible to determine whether the caller can be transferred (S5). This determination as to whether or not the caller can be transferred is executed when the condition for transferring the incoming call to the fixed telephone to the mobile handset is set in advance for the fixed telephone. This condition is registered by the fixed telephone or mobile handset user requesting the cordless telephone exchange system with a special number for setting this condition.
B. of FIG. A specific example is the call transfer registration table of the transfer permission / prohibition of the handset shown in FIG.

B. of FIG. In this field, information for identifying the caller (or caller group) of the incoming call at that time and determining refusal of transfer to the mobile handset is set, and the type code is 1 corresponding to the fixed telephone number. Or, 2 is set, then an allow / disallow flag (when 0 is allowed, when 1 is not allowed), and finally sender information is set. In addition, in the cordless telephone exchange system, the number of the terminal (fixed telephone or mobile handset) making the call from the extension can be identified by the connection control in the caller information, and the incoming call from the office line or trunk line can be identified. Also in this case, since the sender information is notified in the case of ISDN support, it is possible to make a determination using the sender information.

B. of FIG. If the type code of "1" is "1", only the specific calling number shown in the sender information is transferred (permissible flag is 0) or not transferred (permissible flag is 1).
The calling number in this case indicates the extension number when the caller is an extension, and is the telephone number of the caller when the caller is an ISDN office line or an ISDN trunk line. When the type code is "2", it represents a calling group, and only a specific group number (for example, a line number of the office line) indicated in the calling party information is transferred or not transferred.

In step S5 of FIG. 5, B. of FIG.
By referring to the table in Table 1, if any of the following conditions (1) to (4) is satisfied, the transfer to the mobile handset paired with the fixed telephone becomes possible. Is received.

B. of FIG. If the fixed telephone number cannot be found in the table (not registered). When a fixed telephone is found, the allowance flag is "0" (allowable), and the caller information data in the table matches the caller information of the incoming call.

When the fixed telephone is found, the permissible flag (non-permissible) is "1", and the data of the caller information in the table does not match the caller information of the incoming call. When an incoming call is made to the fixed telephone in step S6 of FIG. 5, it is determined whether or not to provide a service in the next mobile handset notification mode.

This mobile handset notification mode is defined as ringing or ringing by a ringer pattern (identifiable) different from that of an ordinary mobile handset when a call arrives at a fixed telephone. This is a mode for controlling to send a message (when the mobile handset has a message display function). Whether or not to provide the mobile handset notification mode service is registered by the user in advance by a special number corresponding to the service from the fixed telephone or the mobile handset, or the "mobile handset notification mode" is set in advance. A button is provided on a fixed telephone or a mobile device, and is set by pressing the button. The information of the mobile handset notification mode is shown in FIG.
A. As shown in, "1" (mode setting) or "0" (unset) is registered corresponding to each fixed telephone.

When the mobile handset notification mode is set, when a call arrives at a fixed telephone and the ringer sounds, an incoming call notification (special ringer ringing, message) is given to the mobile handset near the fixed telephone. (Display) is performed (S9 in FIG. 6), and when the user who knows this notification responds by the mobile slave device, the caller and the mobile slave device enter the call state (S10 in FIG. 6). That is, when the notification mode is set for this mobile slave unit, the control unit of the cordless telephone exchange system monitors the responses of both the fixed telephone and the mobile slave unit and determines which one of the terminals has the faster response operation. Put the caller into a call.

In step S6 of FIG. 5, it is determined whether or not there is a response within a certain time when an incoming call arrives at the fixed telephone (S8 of FIG. 5, corresponding to S5 of FIG. 2). If there is no response within the fixed response delay time (T), this incoming call is transferred to the mobile handset, so that the process proceeds to S5.

In step S5 of FIG. 5, if it is judged that the caller is allowed to transfer the call to the mobile handset, an incoming call is made to the mobile handset (FIG. 6). S11). In this case, it is determined whether the response refusal button has been pressed (S12 in FIG. 6).

This response refusal button is a function button provided in the mobile handset, and when the response refusal button is pressed while the incoming ringer is ringing, it is detected by the control unit of the cordless telephone exchange system. To do. Step S1 in FIG.
When it is identified in step 2 that the response rejection button has been pressed, an incoming call is made to the fixed telephone (S14 in FIG. 6), and when there is a response, the caller and the fixed telephone enter the call state (S15 in FIG. 6). In this case, since the user holding the mobile child device refuses, a response from a user other than the user is expected (S15 in FIG. 6). If the response refusal button is not pressed, the incoming call state of the mobile handset continues.

Further, in step S11 of FIG. 6, it may be determined whether or not there is a response within a fixed time (S13 of FIG. 6), and if there is no response, the call may be transferred to the fixed telephone to receive the call.

[0039]

According to the present invention, when the same user uses both a mobile handset and a fixed telephone, an incoming call to the fixed telephone is automatically made according to the position of the mobile handset held by the user. The call can be transferred to the fixed telephone or transferred to the mobile handset, and the user does not need to register or cancel the transfer service according to the movement.

Further, it is possible to set various conditions desired by the user for the transfer to the mobile child device and selectively transfer only when the conditions are satisfied.
