Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless communication system used for a private telephone system using a PHS, and more particularly to a PBX (Private Branch Exchange).
The present invention relates to a wireless communication system capable of improving reliability and improving the efficiency of maintenance work by changing settings according to the usage of the parameters when setting various parameters in an an) function.

[0002]

2. Description of the Related Art First, a schematic configuration of a conventional wireless communication system, particularly, a private telephone system using a portable device such as a PHS will be described with reference to FIG. FIG. 4 shows a conventional wireless communication system (a private telephone system using a portable device).
FIG. As shown in FIG. 4, a conventional wireless communication system (a private telephone system using a portable device) includes a terminal (portable device) 1 and a connection device 2 for performing wireless communication with the terminal 1.
And a premises PBX (portion surrounded by a dotted line in FIG. 4) for performing telephone exchange control within the premises. Although not shown in the figure, a general telephone or FAX
In many cases, such a communication device is also connected.

A terminal (portable device) 1 is a wireless terminal such as a mobile phone carried by each user in the premises. The connection devices 2 are arranged at various places in the premises, perform wireless communication with the terminal 1, and correspond to base stations in a mobile phone system. The premises PBX manages and controls telephones and terminals 1 located in various places of the premises so that they can be connected by extension numbers, and also connects to external public lines and dedicated lines,
It communicates with an external telephone or FAX and with another premises PBX (such as a branch).

Here, the inside of the premises PBX will be described. The inside of the premises PBX is configured to operate the PBX system as a configuration for operating the PBX system, a plurality of control devices 3 connected to the plurality of connection devices 2 and managing the connection devices 2, and a premises PBX connected to all the control devices 3. An integrated control device 4 for controlling the entire system is provided. Further, a maintenance terminal 5 connected to the integrated control device 4 and performing maintenance such as parameter change of the private PBX system is provided.

[0005] The integrated control device 4 manages and operates the entire premises PBX system. More specifically, the integrated control device 4 determines how to assign an extension number to each telephone and each terminal 1 and whether to group and call the terminal 1 with a telephone number from an outside line. Basic settings in the premises PBX, grouping settings for group calls as a recent function, etc.
The settings of various functions are stored in advance as parameters.
In the operation state, communication control is performed in response to a communication request from each telephone or each terminal 1 in the premises according to the stored parameter setting, and the stored parameter is controlled in response to an external communication request. According to the setting, each telephone in the premises, each terminal 1 and the like are called to perform communication control.

[0006] The parameter settings stored in the integrated control device 4 are usually set to a certain degree (construction setting) by the supplier before the start of operation and delivered as a private PBX system. Is changed from the maintenance terminal 5 to the parameters stored in the integrated control device 4. However, in the case of an in-house PBX system, continuous operation (24-hour operation) is common, so that there is often a possibility that the setting is changed while the parameter to be changed is in use.

Next, an outline of a parameter setting change method in a conventional wireless communication system will be described with reference to FIG. FIG. 5 is a flowchart of a process at the time of parameter setting change in the integrated control device 4 of the conventional wireless communication system. As shown in FIG. 5, when the parameter setting change process starts, first, a parameter change request from the maintenance terminal 5 is input (received) (100). The same applies to not only a change request but also a parameter reading request for confirmation and a parameter erasing request.

Then, it is determined whether or not the operating PBX system is in a state in which parameter change (read, delete) is possible (102). If not (No), the parameter setting change process ends. On the other hand, in the process 102, when the state is the enabled state (Yes), the parameter contents (setting parameters) to be changed are input (received) (10
4) It is determined whether or not the input setting parameter is a normal value (106). If the setting parameter is not a normal value (No), the parameter setting change process ends.
Further, in the process 106, if the setting parameter is a normal value (Yes), the PBX operation parameter is changed (108), a change work completion notification is output (transmitted) to the maintenance terminal 5 (110), and the parameter setting is performed. The change process was terminated.

The prior art relating to the maintenance of the private branch exchange system is disclosed in Japanese Unexamined Patent Application Publication No.
No. 307492 "Remote maintenance method of cordless telephone system" (applicant: Kokusai Electric Inc., inventor: Ryota Kawakami). According to this conventional technique, a maintenance terminal is connected to a control device via a modem and a public line network, and after the end of a call of interest, or during standby, the maintenance terminal is connected to a portable device via a wireless line to transmit setting data. It is not necessary for the worker to go to the site for the ear,
This greatly reduces maintenance work time and man-hours, and significantly reduces work costs.

[0010]

However, in the above-described parameter setting change method in the conventional wireless communication system, it is not checked whether the private PBX is in operation and the parameter to be changed is in use. However, the settings may be changed even during use, causing inconsistency with the current settings, which may cause a trouble, thereby lowering the reliability of the entire system.

Specifically, for example, when the parameter setting of the terminal 1 is changed, the operation of changing the parameter is performed irrespective of whether the terminal is in communication or not. Therefore, there is a danger that the position information in the system of the terminal is duplicated in the program (two or more states occur in one terminal).

Further, as another case, in the case of adding a function of a private PBX, for example, adding a member of a group calling function, it is not checked whether or not the function is being used. Even though voice line control and group member addition caused by an increase in members are performed, there are cases in which parameter changes related to the group calling function, such as changes in the maximum connection group members, are not performed. There is a problem that the operation may be abnormal.

As a method for solving this problem, for example, it is conceivable to check whether the terminal is in a call and not to change the parameters if the terminal is in a call. After waiting, the parameter change operation has to be performed again, and there is a problem that the efficiency of the maintenance operation is low.

The present invention has been made in view of the above-mentioned circumstances, and when changing parameter settings, which is a problem of the prior art, changes unconditionally even during use, causing trouble. And simply abandon the change when in use, to solve the problem of poor maintenance work efficiency and improve the reliability of the entire system by changing the setting according to the parameter usage. It is another object of the present invention to provide a wireless communication system capable of improving maintenance work efficiency.

[0015]

SUMMARY OF THE INVENTION The present invention for solving the above-mentioned problems of the prior art holds an operation parameter, controls connection of a radio terminal according to the operation parameter, and issues an operation parameter change instruction from a maintenance terminal. A wireless communication system having a control device that changes an operation parameter according to the following.When the control device receives an operation parameter change instruction from a maintenance terminal, the control device determines whether the operation parameter is in use, and determines whether the operation parameter is in use. For example, the wireless communication system is a control device that notifies a maintenance terminal of a warning message, monitors the suspension of operation parameters, and changes the operation parameters when the operation is suspended. At the same time, the setting is changed in accordance with the usage status of the parameters, thereby improving the reliability of the entire system, and It is possible to improve the efficiency of the Mamoru work.

It performs operation parameter inquiry processing, change processing, deletion processing, and the like. As a specific example of the operation parameter change processing, when there is an instruction to change a parameter setting from the input unit 51, a parameter to be changed is selected from the input unit 51, and a condition (change) ) Is input from the input unit 51, and the change target parameter and the change condition are transmitted to the integrated control device 4. Here, the change condition is, for example, a condition for change such as whether to abandon the processing unconditionally or make a subsequent inquiry about the response when a parameter to be changed is in use. Then, if a message or a notification of the completion of the change is received from the integrated control device 4 with respect to the transmitted change target parameter and the change condition, the message is displayed on the display unit 52. If so, this is displayed on the display unit 52, the corresponding method is input from the input unit 51, and transmitted to the integrated control device 4.

It is started when there is an instruction to change the terminal parameter setting,
As shown in FIG. 2, first, a terminal to be changed, a parameter and a change condition thereof are input (received) via the communication unit 44.
(200) Then, it is determined whether or not the change target terminal is in use (call) based on the status regarding the change target terminal in the operation parameter storage unit 41 (202). The parameter in the storage unit 41 is changed (214), a change work end notification is output (transmitted) to the maintenance terminal 5 (216), and the parameter setting change process ends.

On the other hand, if the terminal to be changed is in use in the process 202 (Yes), the parameter is not changed unconditionally if the change condition input in the process 200 is in use (if the terminal is in use). It is determined whether or not the setting is abandoned (processing abort) (204). If the setting is to abandon the processing unconditionally (Yes), a message to the effect that the parameter change processing has been abandoned is output (transmitted) to the maintenance terminal 5 (220). Then, the parameter setting change process ends.

In the process 204, if the setting is not to give up the process unconditionally if the terminal is in use (No), a warning message indicating that the terminal is in use is output (transmitted) to the maintenance terminal 5 (206). ), The user inputs (receives) from the maintenance terminal 5 a response as to whether or not to change the parameter after the terminal has been used (208).

Then, it is determined whether or not the response inputted in the process 208 is a response to change the parameter after the use of the terminal is completed (210). If the response is not a response to change the parameter after the use of the terminal is completed (No) ) Jumps to process 220. On the other hand, when the response input in the process 208 is a response to change the parameter after the use of the terminal is completed (Y
es) determines whether or not the terminal is in use (communicating) (212); if not (No), process 212
Is repeated (Yes), the process proceeds to step 214.

Next, the processing at the time of parameter setting change by the operation parameter change control means 42 in the integrated control device 4 of the wireless communication system of the present invention will be described with reference to FIGS. Will be explained. FIG. 3 is a flowchart showing the flow of the member addition / change processing of the group call function of the operation parameter change control means 42 in the integrated control device 4 of the wireless communication system of the present invention. The member addition change process of the group calling function in the integrated control device 4 of the present invention is started when the operation parameter maintenance unit 53 of the maintenance terminal 51 instructs to change the member parameter setting of the group calling function.
As shown in (1), first, a group to be added, an additional terminal, and its change condition are input (received) (300) as a group change request via the communication unit 44, and the group is added according to the status of the additional terminal in the operation parameter storage unit 41. It is determined whether the terminal is communicating (302). If not (No), the process jumps to step 312.

On the other hand, in the process 302, when the additional terminal is communicating (Yes), the change condition input in the process 300 is changed only when both the terminal and the group call are not communicating and OK. Judge whether the setting is (3
04), the setting was changed only when both were OK (Ye
If s), a message to the effect that the parameter change process has been abandoned is output (transmitted) to the maintenance terminal 5 (330), and the parameter setting change process ends.

If it is determined in step 304 that the settings are not changed only when both are OK (No), a warning message indicating that the terminal is communicating is output (transmitted) to the maintenance terminal 5 (306), and Inputting (receiving) whether or not to change the parameter after the communication of the terminal is completed from the terminal 5
(308).

Then, it is determined whether or not the response input in the process 308 is a response to change the parameter after the communication of the terminal is completed (310). If the response is not a response to change the parameter after the communication of the terminal is completed (No) ) Jumps to process 330. On the other hand, when the response input in the process 308 is a response to change the parameter after the communication of the terminal ends (Y
In es), it is determined whether or not the change target group is communicating based on the status of the change target group in the operation parameter storage unit 41 (312). If communication is not in progress (No), the process jumps to step 322.

On the other hand, if the group to be changed is in communication in process 312 (Yes), the change condition input in process 300 is changed only when both the terminal and the group call are not in communication and OK. It is determined whether the setting is a setting (314). If the setting is changed only when both are OK (Yes), the process jumps to the process 330.

If the setting is not changed only when both are OK in the process 314 (No), a warning message indicating that the group is communicating is output (transmitted) to the maintenance terminal 5 (316), and the maintenance is performed. The terminal 5 inputs (receives) a response as to whether or not to change the parameter after the end of the group call (318).

Then, it is determined whether or not the response input in the process 318 is a response to change the parameter after the end of the group call (320). If the response is not a response to change the parameter after the end of the group call (No) ) Jumps to process 330. On the other hand, if the response input in the process 318 is a response to change the parameter after the end of the group call (Yes), it is determined whether the use state of both the terminal and the group (during a call) has ended (322). ), If not completed (No), the process 322 is repeated, and if completed (Yes), the parameter in the operation parameter storage unit 41 is changed (324), and a change work end notification is output to the maintenance terminal 5. (Send) (326), and the parameter setting change process ends.

Next, the operation related to the operation parameter maintenance of the wireless communication system of the present invention will be described with reference to FIG. First, an operation of changing a terminal parameter will be described as an example. The operation parameter maintenance unit 53 is started from the input unit 51 of the maintenance terminal 5, the terminal to be changed, the parameter and the change condition are input from the input unit 51, and the integrated control device is transmitted from the operation parameter maintenance unit 53 via the communication unit 54. 4
To be sent as change data. In the integrated control device 4, the operation parameter change control means 42 receives the change data via the communication means 44, judges whether the change target terminal is in use (call), and if it is in use, inputs the change target terminal first. According to the change condition, if the setting is not to give up unconditionally if the terminal is in use, a warning message indicating that the terminal is in use is output (transmitted) to the maintenance terminal 5, and the operation parameter maintenance means 53 of the maintenance terminal 5 displays the message. A warning message is displayed on the unit 52, and a response as to whether or not to change the parameter after use of the terminal is input (received) from the input unit 51, and the input response method is transmitted to the integrated control device 4.

In the integrated control device 4, if the operation parameter change control means 42 receives the corresponding method and the parameter is changed after the use of the terminal is completed, the operation parameter change control means 42 waits for the terminal to be used and waits for the end of use. Make changes.

Next, an example of a member adding operation of the group calling function will be described. The operation parameter maintenance means 53 is started from the input unit 51 of the maintenance terminal 5, and the group to be added,
The additional terminal and its change condition are input from the input unit 51,
It is transmitted as change data from the operation parameter maintenance means 53 to the integrated control device 4 via the communication means 54. In the integrated control device 4, the operation parameter change control means 42 receives the change data via the communication means 44, determines whether the additional terminal is in use (call), and if the additional terminal is in use, the change input previously entered. If the setting does not change only when neither the group nor the terminal is in use according to the conditions, a warning message indicating that the terminal is in use is output (transmitted) to the maintenance terminal 5 and the operation of the maintenance terminal 5 is performed. The parameter maintenance means 53 displays a warning message on the display unit 52,
After the use of the terminal is completed, a response as to whether or not to change the parameter is input (received) from the input unit 51, and the input response method is transmitted to the integrated control device 4.

In the integrated control device 4, if the operation parameter change control means 42 receives the corresponding method and changes the parameter after the use of the terminal is completed, whether the group to be added is in use (call). Judgment and if in use, group,
If the setting is not to change only when neither of the terminals is in use, a warning message indicating that the group is in use is output (transmitted) to the maintenance terminal 5 and the operation parameter maintenance means 53 of the maintenance terminal 5 is operated. Then, a warning message is displayed on the display unit 52, and after the group has been used, a response to the parameter change is input (received) from the input unit 51, and the input response method is transmitted to the integrated control device 4. .

In the integrated control device 4, if the operation parameter change control means 42 receives the corresponding method and the parameter is changed after the use of the group is completed, the operation parameter change control means 42 waits until the terminal and the group have been used. The parameter is changed.

According to the wireless communication system of the embodiment of the present invention, when the integrated control device 4 receives the operation parameter change instruction from the maintenance terminal 5, it determines whether the operation parameter is in use and determines whether the operation parameter is in use. If not, the operation parameter is changed. If the terminal is in use, a warning message to the effect that the terminal is in use is notified to the maintenance terminal 5 and the user is asked to wait for the end of use to perform the change operation. When instructed to do so, monitor the end of use of operational parameters,
Since the operation parameters are changed at the end of use, when the maintenance worker inputs the change data from the maintenance terminal 5, the operation is performed in the operation parameter storage unit 41 on the integrated control device 4 while the corresponding parameters are being used. Even if it is not possible, the end of use of the parameter is monitored and changed at the end of use, so there is no need for the maintenance worker to wait for the end of use and then input the changed data again, which improves the efficiency of maintenance work There is an effect that can be achieved.

When the integrated control device 4 receives an operation parameter change instruction from the maintenance terminal 5, it determines whether the operation parameter is in use, and if so, sends a warning message to the maintenance terminal. Since the subsequent response is inquired, for example, since the parameters of the terminal being used (call) are not changed, the attributes of the terminal, the destination connection information, and the position information of the terminal in the system are stored in the program. There is no danger that there is a double presence or that two or more states occur in one terminal, and there is an effect that a trouble can be avoided and the reliability of the system can be improved.

In addition, when adding a member of the group calling function, it is checked whether or not the additional terminal and the group function are being used. In addition, it is possible to avoid the occurrence of abnormalities, such as the possibility of changes in parameters related to the group call function even if group members are added, for example, the change of the maximum number of connected group members is not performed normally. This has the effect of reducing the possibility of abnormalities.
