Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone exchange capable of personal communication.

[0002]

2. Description of the Related Art In a conventional telephone exchange such as a PBX, regardless of which service class each terminal user is using and how much, each terminal user has a telephone number corresponding to the accommodation position or telephone number. The service class that can be used by the communication terminal was decided. Therefore, the most familiar communication terminal may not be able to receive the service desired by the terminal user.In that case, you have to move to the place where there is a communication terminal that is permitted to use the desired service class. There wasn't. Also, if you make a confidential call and receive a notification that the confidential callee of the called terminal is absent, or if you want to transfer to the confidential callee because it is in another location, the caller must redial the call. It had to be done and was wasteful.

[0003]

As described above, in the conventional telephone exchange, the use of the service class desired by the terminal user may not be permitted depending on the communication terminal used. In addition, when making a confidential call, when the confidential caller is absent, the call must be redone, which is troublesome.

Therefore, the present invention eliminates these problems,
The purpose is to set a caller-specific service class for a communication terminal regardless of the communication terminal used, and to change the service mode at the request of the caller after a confidential call is received. And

[0005]

The first invention of the present invention is as follows:
In a telephone exchange that can perform personal communication using the personal communication number given to the terminal user, store the personal communication number of the terminal user and the service class that the terminal user can use. A memory means, and a search means for receiving from the memory means the personal communication number of the end user who has input to the terminal when the terminal user makes a call, and searching for the service class permitted for the personal communication number. There is provided a telephone exchange comprising: a setting unit that sets the service class searched by the searching unit for the terminal.

Further, a second invention of the present invention is a telephone exchange which can make and receive a personal call for an individual,
Means for receiving a service mode change request input from the calling terminal in a state in which the personal response of the incoming call does not arrive from the receiving terminal that received the confidential incoming call, and the service related to the incoming call according to the received service mode request Provided is a telephone exchange characterized by comprising changing means for changing a mode.

[0007]

According to the first aspect of the present invention, the personal communication number of the terminal user and the service class that the terminal user is allowed to use are registered in the memory means. Here, if the terminal user inputs the caller's personal communication number,
The search means reads the service class permitted for the personal communication number from the memory means. Then, the service class is set to the communication terminal by the setting means.

According to the second aspect of the invention, when a request for changing the service mode by the caller is input by the caller side terminal in a state where the callee has received a confidential call, and the callee has not yet responded. The changing means changes the current service mode to the requested service mode. The service mode may be changed, for example, from a confidential call (personal call) to a normal station call or from a personal call to a message transfer mode.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a functional block diagram showing an embodiment according to the present invention, in which 1 is a telephone exchange main body, 5 is a connection between extension lines, and an exchange connection is between an extension line and an office line and between an extension line and a dedicated line. This is a replacement circuit. The exchange circuit 5 includes communication terminals 2a to 2m such as telephones via extension interface circuits 6a to 6m.
Respectively connected to. Further, the switching circuit 5 is connected to the public network station lines 3a to 3m via the station line interface circuits 7a to 7m.
It is connected to each 3m. Further, the exchange circuit 5 is connected to the dedicated line 4a via the dedicated line interface circuits 8a to 8m.
Each is connected to ~ 4m. Also, the extension interface circuits 6a to 6m, the station line interface circuits 7a to 7m, and the dedicated line interface circuits 8a to 8
m and the exchange circuit 5 are connected to a control unit 9 that controls the entire telephone exchange. The control unit 9 is connected to a storage unit 10 for registering the communication terminal number, the PID of the terminal user, the service class permitted for each individual terminal user, and the like. Further, the controller 9 controls the maintenance terminal 1 via the digital interface circuit 11.
Connected to 2.

FIG. 2 is a functional block diagram of main parts of the control unit 9 and the storage unit 10 of FIG. In FIG. 2, the dialed digit determination unit 9a is connected to a caller recognition unit 9b, and the caller recognition unit 9b is connected to a personal communication number corresponding service class search unit 9c. Then, the personal communication number-corresponding service class search unit 9c uses the service class setting unit 9d and the personal service class registration table 10a in the storage unit 10.
It is connected to the. Here, the dialed digit determination unit 9a determines whether or not it is necessary to set a service class unique to the caller by the special number in the series of numbers input from the communication terminal. Person recognition unit 9
b extracts the caller's personal communication number (PID) from a series of numbers input from the communication terminal. The personal service class registration table 10a stores the PID of the terminal user and the service class that the terminal user is allowed to use in association with each other. Then, the personal communication number-corresponding service class search unit 9c searches the personal service class registration table 10a for the service class to be set for the caller, using the PID of the caller extracted by the caller confirmation unit 9b. . Upon receiving the search result, the service class setting unit 9d sets the service class for the caller in the communication terminal.

Under the configuration shown in FIGS. 1 and 2, the service class setting operation according to the present invention will be described with reference to the flowchart of FIG. First, the sender is the communication terminal 2
When a special number is input from the terminal, it is sent to the dialed digit determination unit 9a of the control unit 9 via the extension interface circuit 6 and the exchange circuit 5, and it is checked whether or not there is a request to set a personal service class there (S1). . When it is recognized that there is a request, the sender's PID input after the special number is extracted by the sender recognition unit 9b (S2), and the personal communication number corresponding service class search unit 9c extracts the PI.
The personal service class registration table 10a is searched for the service class permitted by D (S3). In the service class setting unit 9d, the service class retrieved by the personal communication number corresponding service class searching unit 9c is
Set for the communication terminal used by the caller (S
4). Since the service class is set by the above operation, it is assumed that the extension number of the communication terminal used by the caller is "3210" as shown in FIG. Even if it is not permitted, the service class is assigned to the personal communication number, not to the communication terminal used as shown in FIG. 4, so it does not depend on which communication terminal is used, and is unique to the caller. Class of service available.

In the present embodiment, the restriction on outgoing calls to the ground is taken as an example of the service class, but it is also possible to apply it to other services provided by the exchange.

Next, another embodiment of the present invention will be described. In this embodiment, in the personal communication system using PID, the service mode can be changed at the request of the caller after the confidential incoming call. The hardware configuration of the system is almost the same as that of the previous embodiment shown in FIG.

The operation will be described below. First, the caller selects a personal call from a certain communication terminal 2a, and then his PID
Enter. Then, when the personal communication number (called PTN) of the other party (confidential receiver) who wants to make a confidential call to the called terminal is input, the input PID and the called PTN are sent to the control unit 9 via the extension interface circuit 6. Sent. The control unit 9 refers to the storage unit 10 (where the terminal number and the personal number are stored) and reads the terminal number (for example, the terminal 2m) of the terminal user having the received destination PTN. When a call origination request is input from the communication terminal 2a, the control unit 9 receives the request and calls the destination communication terminal 2m via the extension interface circuit 6m. The destination terminal 2m designates a specific individual (confidential receiver) by the destination PTN to receive an incoming call.

After that, there may be no response from the receiving side terminal 2m, or the absence notification may be sent from the receiving side terminal 2m to the calling side terminal 2a because the confidential receiver is absent. In such a case, if the communication content is such that not only the confidential call receiver but also another terminal user on the spot can respond by proxy, the caller operates one of the function keys provided on the calling terminal 2a. Thus, the service mode change request can be issued from the currently set “personal call” to “station call”. The control unit 9 receives this request,
A "station call" signal is sent to the destination terminal 2m via the extension interface circuit 6m. Receiving this, the receiving-side terminal 2m performs a calling operation to recognize that it is a "station call" by changing the ring tone or displaying a message. Thereby, an appropriate person near the receiving side terminal 2m can respond. Alternatively, the caller can send a message from the caller terminal 2a to the callee terminal 2m by operating another function key. In this case, the receiving-side terminal 2m stores the message, and then the confidential receiver can read the message later by inputting the PID.

The above operation will be summarized with reference to FIG. FIG. 6 is a sequence diagram of the operation according to the present invention. First,
The caller selects a personal call (S11), a special number, P
When the ID and the destination PTN are input (S12) and the call key is pressed (S13), those input data are sent to the control unit of the exchange, and the number of the called terminal used by the confidential recipient based on the destination PTN. Is searched (S14). Then, a confidential transmission is made from the exchange to the receiving side terminal by the "receiving PTN". At the receiving side terminal that receives a confidential incoming call (personal call), the terminal user is notified of the "personal call" by a ring tone or a message (S
15). If there is no response here because the confidential callee is absent, or if the “absence notification” is sent because the “destination PTN” is registered as an absence (S16), the caller has the following two types. The operation can be selectively performed. One is to change the service mode from "personal call" to "station call" by calling a specific function key (S17). in this case,
The called terminal receives this service mode change request,
The terminal user is informed of the "station call" by changing the ring tone or a message (S19).
As a result, an appropriate person on the spot can respond, and if answered, a call can be made with the caller (S20). Another option is to change the service mode from "personal call" to "send message" by pressing another function key (S21). In this case, the caller inputs a message, and since this message is stored in the called terminal, the confidential callee can later read the message by entering his PID (S26).

[0017]

As described above, according to the present invention, the service class unique to each terminal user can be used without being limited to the service class allowed for each communication terminal. When a confidential call is received, the service mode can be changed according to the caller's request until the confidential call is answered. Therefore, it becomes easier to connect to the partner terminal, and information can be transmitted smoothly.
