Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for controlling incoming calls to a fixed telephone and a mobile phone in a cordless telephone exchange system. [0002] In recent years, with the spread of cordless telephones, cordless telephone exchange systems have been widely used in offices and factories. In a cordless telephone exchange system,
A fixed telephone, a base unit arranged in each zone, and an office line are connected to the exchange by wire, and the base unit in each zone communicates with the mobile unit wirelessly. [0003] In such a cordless telephone exchange system, a user of a fixed telephone is often used while holding a mobile phone at the same time. In this case, the fixed telephone and the mobile phone have different telephone numbers, respectively.
When the user is in his / her own seat, the user can make and receive calls using a fixed telephone, and when leaving the seat, carry the mobile handset and register the destination so that the mobile handset receives the call. However, it is desired that a call can be received to a mobile terminal or a fixed telephone without burdening the user. FIG. 8 is an explanatory diagram of a conventional example. The cordless telephone exchange system includes a control unit 81 in a network 80 of exchanges, and a number of fixed telephones 85 connected to the network 80 by wires are installed in a room where each department of a building such as a building in which an office is located. Each is installed. Each floor of the building is provided with a base unit 83 connected to the exchange by a wire, and each base unit 83 has a mobile unit (portable cordless telephone) in a zone 82, which is an area where radio signals can reach. ) 84 and wireless telephone communication. In the example of FIG. 8, each of the zones 1 to n corresponds to the first to nth floors of the building, and the master unit 83 is arranged in the zone of 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 user as the fixed telephone 85 user. Has disclosed the telephone number of the mobile phone in addition to the desk phone. If you are not present, ask the caller to call back your mobile phone number,
Registration is made to receive the call forwarding service from the desk phone to the mobile terminal, and the destination mobile terminal receives the incoming call by the call forwarding. To receive the conventional call forwarding service,
Before moving, the user dials the special number for requesting call forwarding registration to the exchange, and registers the number of the mobile terminal and the zone number of the destination as the transfer destination. Thereby, the control unit 81 of the network 80 registers the number of the mobile terminal and the zone number in the memory as the transfer destination of the fixed telephone number. Thereafter, when a call arrives at the fixed telephone, it is checked whether call forwarding is registered for the fixed telephone. If the call is registered, the mobile terminal of the registered number is set to the base unit 83 of the registered zone. Call by wireless. A call can be made by receiving this call with the mobile terminal carried by the destination user. [0007] In this way, it is possible to receive an incoming call even at the destination by the mobile child device held by the user. After registering for this call forwarding, after the user returns to his / her seat,
In order to enable calling and receiving by a fixed telephone on a desk, it is necessary to perform the same dialing operation for canceling registration as in registration in order to cancel call forwarding registration. [0008] As described above, in the conventional cordless telephone exchange system, a user who has a fixed telephone and a mobile phone receives an incoming call to the fixed telephone when leaving his / her seat. If the user wishes to receive the call at his or her destination at his or her destination, it is necessary to perform a call forwarding registration operation using a fixed telephone beforehand in order to receive the call forwarding service, which is troublesome. [0009] Another problem is that if the user forgets to cancel the call forwarding registration when he / she returns to his / her seat, the user will not be able to receive the incoming call because the call will arrive at the registered zone. According to the present invention, when a user using a fixed telephone and a mobile terminal moves an incoming call without any operation, the fixed telephone or the user moves the mobile terminal with the mobile terminal to the destination mobile terminal. It is an object of the present invention to provide an incoming call control method for a cordless telephone exchange system that can receive an incoming call. FIG. 1 is a basic configuration diagram of the present invention. In FIG. 1, 1 is a network of exchanges,
1a is a wireless control unit, 2 is a control unit, 3 is a memory, 4a, 4
b and 4c are fixed telephones; 5a and 5b are base units connected to the network 1 for wirelessly controlling connection with mobile units in the zone; 6a is a mobile unit used by a user of the fixed telephone 4a; Denotes a mobile terminal used by a user of the fixed telephone 4b, 7a, 7b, and 7c denote zones a, b, and c, respectively, and 8 denotes a telephone line, an ISDN-compatible office line, a trunk line, or the like. It is an outside line. The control unit 2 is provided with a memory. In the memory 3, 30 is a first table, 31 is a second table,
32 is a third table. The first table 30 stores a fixed telephone number and a mobile terminal number used by a user of the fixed telephone in association with each other, and determines whether or not to receive the service for each service provided to the fixed telephone. An area for setting is provided. The second table 31 stores the mobile terminal number, the home zone of the mobile terminal (the zone where the corresponding fixed telephone is located) and the current zone (including the destination). Further, the third table 32 stores information on callers whose fixed telephone users accept or reject incoming calls. A mobile terminal corresponding to a fixed telephone number is registered in advance in a first table 30 provided in a memory 3 of the control unit 2, and a mobile terminal corresponding to a mobile terminal number in a second table 31 is registered. The number of the own zone (home zone covering the position where the user is usually located) is registered in advance. When the user of the mobile child device moves with the mobile child device to another zone, the destination zone is registered by a conventional technique. That is, when an inquiry signal is generated from a master unit corresponding to a zone, a response is returned from a mobile slave unit in the zone, so that the zone in which the mobile slave unit exists is automatically detected or registered. When the user of the machine performs a location registration operation, a signal is generated, and the master machine in the zone detects the signal and the registration is similarly performed. The control unit 2 of the cordless telephone exchange system sets the zone of the registered mobile terminal
The zone is set as the zone where the mobile unit is currently located in the second table 31 of the memory 3, and is updated each time a movement occurs. When an incoming call to the fixed telephone 4a from the outside line 8 or another extension telephone 4c or the like occurs, the control unit 2 of the cordless telephone exchange system determines that the mobile terminal 6a corresponding to the fixed telephone 4a exists. When detected in the first table 30, the current registration position of the mobile terminal 6a is identified by the second table 31, and if the mobile terminal 6a is registered in the own zone 7a, the incoming call is made to the fixed telephone 4a, but is registered in the other zone 7b. If so, the call is forwarded to the mobile terminal 6a, and the mobile terminal 6a receives the call from the parent device 5b in another zone. When an incoming call is received by the mobile phone 6a, the control unit 2 regulates outgoing and incoming calls by the corresponding fixed telephone 4a. If the mobile terminal 6a is registered in its own zone and a response is not received within a certain time even if it is received by the fixed telephone 4a, it is possible to control the transfer to the corresponding mobile terminal 6a. . A mode (service) in which the mobile terminal 6a is registered in its own zone 7a, and simultaneously notifies the mobile terminal 6a of the presence / absence of a call when a call arrives at the fixed telephone 4a.
Is set in advance, it is possible for the mobile telephone 6a to respond when an incoming call arrives at the fixed telephone 4a. Further, the mobile terminal 6a is registered in the other zone 7b and the fixed telephone 4a
When a call is forwarded to mobile terminal 6a and received, and mobile terminal 6a does not respond for a certain period of time, the call can be retransmitted to fixed telephone 4a. When the mobile terminal 6a is registered in another zone, a caller (or group) who permits or prohibits an incoming call from the mobile terminal 6a or the fixed telephone 4a in advance.
Is specified in the third table 32 of the memory 3. In this case, if the mobile terminal 6a is registered in the other zone 7b, a call arriving at the fixed telephone 4a is transmitted to the caller (for example, FIG. 1) before being transferred to the mobile terminal 6a.
) Of the call received from the fixed telephone 4c or the outside line 8 of the extension, and determines whether or not the caller is registered in the third table as caller information permitting the call. Only when the condition is satisfied, incoming calls to mobile units in other zones are permitted, and if not, incoming calls are rejected. 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 the arrangement of fixed telephones and mobile terminals corresponding to zones, and FIG. 4 shows a specific example of a table referred to in the processing flow of FIG. Referring first to FIGS. 3 and 4,
The fixed telephone 11 (telephone number 2100) accommodated in the network 10 forms a pair with the mobile terminal 12 (telephone number 3100). That is, the mobile terminal 12 is exclusively used by the user of the fixed telephone 11. In this case, FIG. The correspondence table between the fixed telephone and the mobile phone shown in FIG.
(Corresponding to the table 30). If there is no mobile terminal corresponding to the fixed telephone as in the example of the telephone number "2101", the fact that there is no mobile terminal is displayed (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 terminal 12 is the zone 1, and the base unit 13 is located in the zone 1. FIG. 3 shows a state where the user holding the mobile handset 12 has moved to the zone 3 as indicated by the dotted line. In the state where the mobile child device 12 has thus moved, the current position of the mobile child device 12 is registered by the conventional position registration technique. In this case, FIG. The home zone is set to "1" and the current zone is set to "3" in the accommodation zone table (corresponding to the second table 31 in FIG. 1) of the mobile terminal shown in FIG. . The processing flow of FIG. 2 will be described with reference to FIGS. When an incoming call to the fixed telephone occurs, it is checked whether there is a pair of mobile terminals or not. (S1 in FIG. 2). At this time, if the telephone number of the called party is "2101", there is no mobile phone of the pair, and 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”, a pair of mobile terminals exists and the telephone number of the mobile terminal is identified by the correspondence table of the fixed telephone and the mobile terminal. In this case, the mobile terminal is in its own zone (home zone) or B. in FIG. The determination is made by referring to the accommodation zone table of the mobile child device as shown in FIG. According to this table, if the current zone of the mobile unit matches the own zone (home zone), an incoming call is made to the fixed telephone, otherwise, an incoming call is made to the mobile unit located in the destination zone. (S4 in FIG. 2). At this time, outgoing calls and incoming calls to the pair of fixed telephones are regulated. The control of the incoming call to the fixed telephone or the mobile unit is completed by the above S4. However, as an additional service process for the user, the incoming call to the fixed telephone and the ringer sounds and the ringer sounds within a certain period of time. It is determined whether a response has been made (S in FIG. 2).
5) If there is no response, it is possible to control the mobile terminal in the home zone to receive the call. It should be noted that if there is a response to the incoming call to the fixed telephone within a certain period of time, the telephone will be in a call state. The predetermined response delay time (T), which is a reference for the determination in S5, can be changed by a maintenance / operation command of the cordless telephone exchange system.
FIGS. 5 and 6 show processing flows (part 1) and (part 2) of an embodiment for providing a plurality of selectable services. FIG. 7 shows a table referred to in the processing flows of FIGS. Is also referred to. Here, FIG. In FIG. The data required to provide a plurality of services are registered in the correspondence table of the fixed telephone and the mobile phone shown in (1), and the contents of each data will be described in the processing of each service described later. B. of FIG. Is an outgoing call registration table (refer to FIG. 1) for registering whether or not to permit or reject the transfer from the fixed telephone to the mobile handset.
Table 32). In FIG. 5, when an incoming call request to the fixed telephone is generated, the fixed telephone determines whether the incoming call is rejected (S1 in FIG. 5). This determination is made according to A.A. Is performed by referring to the "Receiving incoming call" column corresponding to the telephone number of the fixed telephone in the table shown in FIG. The incoming call restriction information can be obtained by the user dialing a special number “call rejection service number” from the fixed telephone or mobile phone to the cordless telephone exchange, or providing a “call rejection” registration button on the fixed telephone in advance. "Call rejection" by pressing the registration button
Is transmitted to the system by sending a request for registering the. By registering, A. in FIG. A flag ("1") is set in the "Restriction on incoming calls" column corresponding to the telephone number of the fixed telephone that made the request in the table shown in (1). If no registration has been made, the flag is not set ("0"). In S1 of FIG. 5, A.P. When the flag of “reception restriction” is set with reference to the table of “1”, the control unit restricts the incoming call to both terminals (the fixed telephone and the mobile unit of the pair), and the caller cannot receive the call. When a tone is supplied (S2 in FIG. 5) and the mobile phone is not set, whether there is a mobile phone paired with the fixed telephone or not. (S3 in FIG. 5), and if there is no table, the process proceeds to S14 in FIG. 6 to receive a call to the fixed telephone. If there is a pair of mobile terminals, it is determined whether or not the mobile terminal exists in the own zone by referring to the table (B in FIG. 4). S6 of FIG. 6, FIG.
Same as S14). If it is determined in S4 of FIG. 5 that the mobile terminal is not in the own zone, it is possible to determine whether or not the caller can be transferred (S5). This determination as to whether or not the caller can be forwarded is performed when a condition has been set in advance as to whether or not an incoming call to the fixed telephone is to be transferred to the mobile terminal. This condition is registered by the user of the fixed telephone or mobile unit making a request to the cordless telephone exchange system with a special number for setting this condition.
B. of FIG. Is a specific example. FIG. Is set with information for identifying a caller (or a caller group) of the incoming call at that time and determining refusal of transfer to the mobile terminal, and a type code of 1 corresponding to the fixed telephone number is set. Or, 2 is set, then an allowance / non-allowance flag (allowed if 0, unacceptable if 1), and finally sender information. In a cordless telephone exchange system, the number of the terminal (fixed telephone or mobile phone) that made a call from an extension can be identified by connection control, and the caller information can be used to identify incoming calls from central office lines or trunk lines. Also in this case, since the sender information is notified in the case of ISDN correspondence, it is possible to make a determination using the sender information. FIG. If the type code is "1", only the specific calling number indicated in the caller information is transferred (the permission flag is 0) or non-transferred (the permission 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 indicates a transmission group, and only a specific group number (for example, a line group number) indicated in the caller information is transferred or non-transferred. In step S5 of FIG.
By referring to the table, if any of the following conditions is satisfied, the transfer to the mobile phone paired with the fixed phone becomes possible. Otherwise, the transfer to the mobile phone is not allowed and the fixed phone is not allowed. Is received. FIG. When the number of the fixed telephone is not found (not registered) in the table. When a fixed telephone is found, the permission flag is "0" (permission), and the data of the caller information in the table matches the caller information of the incoming call. When a fixed telephone is found, the permission flag (non-permission) is "1", and the data of the sender information in the table does not match the sender information of the incoming call. When an incoming call to the fixed telephone is made in step S6 of FIG. 5, it is determined whether or not a service in the next mobile terminal notification mode is provided. The mobile terminal notification mode refers to ringing or ringing of a ringer pattern that is different (identifiable) from that of a normal mobile terminal when a call is received to a fixed telephone. In this mode, control is performed to send a message (when the mobile child device has a message display function). Whether or not to provide the mobile handset notification mode service is determined by the user registering in advance from a fixed telephone or a mobile handset using a special number corresponding to the service, or setting a “mobile handset notification mode” in advance. A button is provided on a fixed telephone or a mobile phone, and is set by pressing the button. The information of the mobile terminal notification mode is shown in FIG.
A. "1" (mode setting) or "0" (unset) is registered corresponding to each fixed telephone as shown in FIG. When the mode is set in the mobile terminal notification mode, when a ringer rings upon receiving an incoming call to a fixed telephone, an incoming call notification (special ringer ringing, message Display) is performed (S9 in FIG. 6), and when the user who has received the notification responds with the mobile terminal, the caller and the mobile terminal enter a talking state (S10 in FIG. 6). That is, when the notification mode is set for this mobile device, the control unit of the cordless telephone switching system monitors the responses of both the fixed telephone and the mobile device, and determines whether the response operation of any terminal is faster. Put the caller on a call. In step S6 of FIG. 5, it is determined whether there is a response within a predetermined time when receiving a call to the fixed telephone (S8 in FIG. 5, corresponding to S5 in FIG. 2). If there is no response within a predetermined response delay time (T), the process proceeds to S5 to transfer the incoming call to the mobile terminal. In step S5 of FIG. 5, if it is determined that the transfer to the mobile device is permitted by the caller, the call is received by the mobile device (FIG. 6). S11). In this case, it is determined whether the response rejection button has been pressed (S12 in FIG. 6). The response rejection button is a function button provided on the mobile terminal, and when the response rejection button is pressed while the ringer for the incoming call is sounding, the control unit of the cordless telephone exchange system detects this. I do. Step S1 in FIG.
In step 2, when it is determined that the response rejection button has been pressed, an incoming call is made to the fixed telephone (S14 in FIG. 6). In this case, since the user holding the mobile handset refuses, a response from the user other than the use is expected (S15 in FIG. 6). If the response rejection button is not pressed, the incoming state of the mobile terminal continues. In step S11 in FIG. 6, it may be determined whether or not there is a response within a predetermined time (S13 in FIG. 6). According to the present invention, when the same user uses both the mobile phone and the fixed telephone, the incoming call to the fixed telephone depends on the position of the mobile phone held by the user. The call can be automatically received at the fixed telephone or transferred to the mobile device, so that the user does not need to register or cancel the transfer service according to the movement. Further, various conditions desired by the user for the transfer to the mobile unit can be set, and the transfer can be selectively performed only when the conditions are satisfied.
