Description

[0001]
[Industrial applications]
The present invention relates to an information exchange system in which a plurality of terminals connected to a communication network and a plurality of mobile terminals registered in the communication network mutually exchange information by designating an access number.
[0002]
[Prior art]
Information and communication technology will be able to handle the transmission of voice, text data, image data, and video by converting the information handled to multimedia, and for networks, in addition to wire-based information exchange, mobile devices that use radio waves, infrared rays, etc. Terminals have been developed for information exchange.
[0003]
In particular, mobile communication has conventionally been used as a convenient tool that allows a mobile terminal such as a mobile phone or a mobile phone to talk from anywhere in a wide area. In addition, along with the digitization, not only voice but also text data and image data can be transmitted and received from a free place, thereby contributing to business efficiency.
[0004]
In addition, the use of mobile terminals in a wider field is being promoted with a simplified mobile phone system (PHS: Personal Handy Phone System), which will soon be implemented for expensive mobile terminals and their usage fees. The communication speed is even faster than that of digital mobile phones, and it is expected to be a multimedia mobile terminal in the future.
[0005]
There are currently three ways to use PHS. In other words, as an extension of the conventional digital cordless telephone, a private system operated indoors and inside a company, an outdoor public system operated by a telephone company in a public area, and a system in which mobile terminals individually communicate with each other as a transceiver. Yes, these modes of use are switched by operating buttons on the mobile terminal, and can be selectively used as needed. Normally, business usage is the same as the former two, used for internal communication within a narrow area such as in a company building or factory premises, or a public system using a mobile terminal carried when going out of the office. It can be used in a wide range by connecting to a public network that can be used and connected to a general telephone.
[0006]
FIG. 9 is a diagram for explaining a conventional technique, that is, how to use PHS. In the figure, an area A within a large circle 91 indicates an area where radio waves of the above-mentioned public system reach, and a base station of a telephone company finely spreads an antenna and moves a mobile terminal a in the area to the public system. It enables information exchange with mobile terminals and telephones and terminals in the public telephone network located in Japan.
[0007]
Areas B, C, and D indicated by small circles 92, 93, and 94 are bases of a self-employed system in a business establishment (in a building or on a premises) connected to a conventional private branch exchange that exchanges business extension telephones. Indicates the radio wave propagation area of the station antenna. The mobile terminals b, c, and d indicate that they are currently located in the areas B, C, and D, respectively.
[0008]
The mobile terminals b, c, and d registered in the private systems of the areas B, C, and D, respectively, may receive the radio waves of the base station of the public system depending on the location in each area. As described above, the mode is changed by operating the switches of the mobile terminals b, c, and d. Therefore, if the switch is in the public mode, if a radio wave of the public system is delivered, the mobile terminal can be directly used as a normal independent mobile phone. By turning a general telephone number, you can make a call or exchange data with a computer.
[0009]
When the operation mode is the self-operating mode, even if the mobile terminal b, c, d receives the radio wave of the public system, the mobile terminal b, c, d cannot be connected to the public network, and is registered in each area B, C, D. The mobile terminal is connected to the private branch exchange by capturing the radio wave from the antenna of the private system and positioning the extension telephone at the office.
[0010]
The term "mobile terminal registered in the private system" used here means that if the system is a public system, the mobile terminal is approved by the public network operating company so that it can be connected to the public network. Just as only the terminal is selected and communication by radio wave is possible, and the usage fee is charged to the user based on the record of the communication, the limited mobile terminal " Only mobile terminals registered in the private system are connected to the extension by radio wave communication.
[0011]
This is because if you connect to an outside line, there is a cost of using the public network, and the capacity design of the private branch exchange is also determined based on the number of mobile terminals, so it is selfish for outsiders. The extension is not opened. This is also necessary because the mobile terminal cannot be used as an incoming terminal from another terminal unless an extension telephone number is given. Therefore, the ID of the mobile terminal that can be used in the business office is registered in advance, and even if the mobile terminal transmits a radio wave of a connection request, the mobile terminal that does not have the registered ID is not connected. ing.
[0012]
In FIG. 9, when the mobile terminal a is also brought into the area B, it can be used as a mobile terminal of a public system by communicating radio waves with the area A depending on the radio wave condition. When the mobile terminal a is registered in the private system of B when trying to use it as an extension telephone of B, it can be used as an extension telephone, or a computer connected to and used to access a computer in the office. However, if a is a mobile terminal that is not registered in the private system B, communication is rejected. Even if the mobile terminal d is registered in the private system D and enters the area C but is not registered in the private system C, the mobile terminal d is similarly connected to the private branch exchange of the office of C. Not done.
[0013]
Here, even if B and C are business establishments of the same company, the extension numbers managed by each business establishment are independent, and mobile terminal b registered at business establishment B has business extension B When the user leaves the office and goes on a business trip to the office of C, the function as the mobile terminal cannot be exhibited except where the radio wave of the public system reaches.
[0014]
[Problems to be solved by the invention]
As described above, according to the conventional technology, even if the mobile terminal at the same time is within the same company, for example, it cannot be used as an extension phone when traveling to another office, and the personal computer is connected to the center to process the business In particular, the radio wave of the public system does not reach the inside of the building, and the user simply sleeps in a bag (claims 1 and 3).
[0015]
In addition, even if there is a visitor such as a VIP, if it is possible to connect to a familiar mobile terminal using an external telephone, it is necessary to use a non-free calling phone to improve the service. (Claims 2 and 4).
[0016]
As described above, the characteristics of mobile terminals cannot be fully exploited, and even conventional mobile terminals can be connected to the extension of their business office and used as public terminals within the range of radio waves of the public system. There is a problem that it can be connected to the network, but cannot be used in the radio wave area of the private system where the ID is not registered.
[0017]
In view of such a point, the present invention
Even if the mobile terminal has no ID registered in the self-owned system, the ID can be automatically registered as a guest and a guest access number can be given as an extension number to connect to an extension and make a call. As described in (3), the assigned extension number (access number) is notified to the mobile terminal to enable reception (claims 2 and 4), and means for enabling connection to the private branch exchange is provided. The purpose is to provide.
[0018]
[Means for Solving the Problems]
The above object is to provide a unique access number corresponding to a plurality of terminals connected to a communication network and IDs of a plurality of mobile terminals registered in the communication network, and to designate the access number Then, in the information exchange system in which the plurality of terminals and the mobile terminal exchange information with each other, the problem is solved by the information exchange system configured as follows.
[0019]
FIG. 1 is a configuration diagram of the present invention.
The guest access number management table 2 manages a guest access number for connecting a mobile terminal having an ID that has not been registered in the communication network to the communication network. When a mobile terminal having an ID of 1 is requested to connect to the communication network, an unassigned guest access number in the guest access number management table is automatically assigned in accordance with the ID of the mobile terminal. is there. Thereby, the mobile terminal provided with the guest access number can exchange information with another terminal and the mobile terminal (claims 1 and 3).
[0020]
The guest access number notifying means 3 notifies the assigned guest access number to the mobile terminal assigned the guest access number (claims 2 and 4).
[0021]
[Action]
A guest access number management table 2 for managing a guest access number for connecting a mobile terminal having an ID not registered in the communication network to the communication network is prepared, and the mobile terminal having the unregistered ID is When a connection to the communication network is requested, an unassigned guest access number in the guest access number management table 2 is automatically assigned according to the ID of the mobile terminal. Accordingly, the mobile terminal to which the guest access number is assigned can transmit and exchange information with another terminal and the mobile terminal (claims 1 and 3).
[0022]
In addition, the assigned guest access number is notified to the mobile terminal to which the guest access number has been assigned (claims 2 and 4). However, the mobile terminal can receive.
[0023]
【Example】
FIG. 2 shows a configuration diagram (part 1) of the embodiment of the present invention.
FIG. 2 also shows the usage status of the mobile terminal at a certain point in the office A of a certain company. Reference numeral aa denotes a mobile terminal 212 at the office A, which is used by moving within the premises. be is a mobile terminal 342 normally used at the B office of the same company, and is currently used by a business traveler at the A office for work on the premises of the A office. CS22 is a base station of a private system of the establishment A, and a plurality of similar base stations are arranged in the premises so that they can be used by moving within the premises. The CSC 23 controls a radio signal with the mobile terminal transmitted and received by the base station. In addition to control for conversation, an authentication operation for confirming that the mobile terminal is a proper one, It is responsible for grasping the position of the vehicle. The NW 24 performs a network switch of the private branch exchange and is a main part of the private branch exchange. The central control unit that controls the exchange process of the terminal 211 and the mobile terminals 212 and 342 connected to the private branch exchange is the CC 26, and performs the function of the exchange by various management information stored in the main memory MM27. . The private branch exchange is connected to a public network through a central office trunk COT25 in addition to information exchange between various terminals connected to the extension, or is connected to another business office or the like by a dedicated line in the company.
[0024]
A part of the contents of the MM 27 is necessary for the management of the mobile terminal, and will be described in detail later. One is a registration ID table 291 which compares the registration ID with the extension number. One is a registration ID table 291 which is a guest ID table 292 which is a mechanism for connecting a mobile terminal carried by a customer such as a VIP or a business traveler from another business office such as be to a private branch exchange network. The mobile terminal IDs are aa, ab, ac, and ad, and extension numbers 1010, 1020, 1030, and 1040 are given.
[0025]
Also, extension numbers 2010 and 2020 are prepared in the guest ID table 292, which indicates that the mobile terminal whose guest ID is be is currently assigned the extension number 2010, and the extension number 2020 is unassigned. State.
[0026]
FIG. 3 shows a configuration diagram (part 2) of the embodiment.
A fax is connected to aa registered as a mobile terminal at the office A, and a personal computer is connected to ac. Since digital signals can be handled at a high speed, familiar devices can be connected to a network at a free place. As described above, the simple connection method using the guest ID of the present invention is useful in order to take advantage of the fact that it can be used not only as a telephone but also with various portable devices and used for business as a personal mobile terminal. I understand.
[0027]
The arrow 39 indicates that be traveled from the office B to the office A and moved. It can be seen that be is registered in the registration ID table 36 of the establishment B in the private system of the establishment B by the extension number 501 and the ID is registered.
[0028]
As a connection partner of be, not only the computer 211 of the office A but also the computer of the office B, which is connected to the internal office dedicated line 37 and is always used by the extension at the office B (not shown), and B You can also freely contact the office by telephone.
[0029]
However, the private branch exchange of the office A has an outside line 38 connecting the inside and outside of the city, which is a connection path to the public network. Normally, the extension telephone at the office A is used as a communication tool with other extensions in the premises, and is connected to a customer or an external organization that is not connected by a dedicated line using an external line. At this time, the operating company of the public network naturally charges and uses the line.
[0030]
There is no problem for such a mobile terminal having a guest ID until connection to an extension, so there is no problem, but it is necessary to restrict outside lines. Outgoing calls are restricted so that even a telephone connected to a normal private branch exchange is not easily connected to an outside line.
[0031]
As shown in the explanatory diagram of the guest ID table of FIG. 4, each guest ID, that is, the mobile terminal is restricted from outgoing calls, extensions, and cities in the connection range item. Due to this call restriction, the guest's mobile terminal is usually limited to an extension only to reduce the cost. Here, the inside of the city and the outside of the city are outside lines, and there is a cost for the outside. The setting of these regulation values for each mobile terminal will be described later.
[0032]
The configuration of the guest ID table 44 will be described.
The guest ID table 44 is basically a correspondence table with the guest extension telephone number when the ID of the mobile terminal of the guest is used in the private system as described above. FIG. 4 further includes items of date and time of grant, extension time limit, and connection range.
[0033]
The date and time of assignment is recorded when a guest extension number is assigned, and is a time stamp for recording the use of the extension for a later date. As will be described later, the guest registration is automatically canceled at night every day in order to make effective use of the limited number of extensions for guests. The deadline can be extended. This is achieved by recording the extension period in units of days and months.
[0034]
The above-mentioned setting of the extension term and the connection range will be described later in a flowchart as a regulation value changing operation.
Note that the guest ID is displayed in alphabets such as be, but is actually a number. Similarly, the connection range is displayed in Kanji, such as outside the city or inside the city, but is represented by a number. Thus, settings can be changed using the numeric keys of the mobile terminal.
[0035]
Hereinafter, each operation will be described with reference to a flowchart.
FIG. 5 is a flowchart for explaining the transmission operation of the mobile terminal.
When trying to make a call using the mobile terminal, that is, at the stage where CS22 receives the radio wave transmitted from the mobile terminal and performs a prior confirmation such as authenticating that the mobile terminal is a legitimate mobile terminal. A program for calling operation processing of the mobile terminal in the CC 26 is started. First, in step S52, it is necessary to search the ID registration table with the ID of the mobile terminal to know the extension number.
[0036]
If it is not registered in the ID registration table, it is also checked whether or not it has already been registered in the guest ID table. If it has been registered in any of the tables, the extension number is obtained from the ID registration table in step S53, and the calling operation proceeds as a normal operation and dialing allows information exchange with the terminal of the other party's telephone number.
[0037]
If it is determined that the ID is an unregistered ID, in step S55, first, the guest ID table is checked to see if there is an empty extension number. If there is no vacant extension number, it is determined that there is no line to be assigned to the guest, and "busy" is notified to the mobile terminal. In this case, the guest ID cannot be used until another guest terminal does not need the guest ID and the deletion operation is performed spontaneously, or the entire guest ID table is automatically deleted and newly assigned. However, it is necessary to adjust the number of guest ID extension numbers available to the guest number manager. For this purpose, the occurrence of the situation of notifying "busy" is recorded together with the date and time and the ID (S60).
[0038]
If there is a vacancy in the guest ID table and an extension number is assigned, the guest ID is recorded together with the date and time in step S56. It is unnecessary if the guest mobile terminal is not charged, but it is also a mobile terminal that has visited from the outside and is left as a call record of one of the security measures for later. In step S58, the extension number assigned in the guest ID table is notified to the mobile terminal by voice and display. The user of the mobile terminal can directly receive the information to be received by notifying the extension number notified here to the information exchange partner until the mobile terminal is deleted thereafter. Thereafter, in the calling operation, a normal dial calling operation proceeds in step S54.
[0039]
FIG. 6 shows a flowchart for explaining the operation of the number notification.
As described above, an extension number is assigned when making a call for the first time, and the extension number is notified to the corresponding mobile terminal, but if you forget to take a note or lose the note, it will be used as a guest ID. Since it is registered, you can make outgoing calls freely, but this is a problem when someone wants to call this number and you want to use it as a receiving terminal. In such a case, the number notification can be obtained any number of times.
[0040]
This program is activated when a call is made from the mobile terminal to an extension number designated as “extension number inquiry special number”. In step S62, the guest ID table is searched using the ID of the mobile terminal that has sent the call as a key to find a corresponding extension number. Here, the extension number is notified by voice and display in step S63. After confirming the confirmation, end the process.
[0041]
FIG. 7 is a flowchart illustrating the operation of changing the regulation value.
As described above, the range in which the guest mobile terminal can transmit and exchange information is not allowed to connect to external lines that would newly incur external costs. For example, if it is necessary to make a call to a toll line in order to perform a special task on a business trip, the outgoing expenses will be borne by the business establishment of the self-employed system, or the mobile terminal In the case where payment is made between business establishments based on the call records collected by ID, a telephone number capable of making an outgoing call can be assigned.
[0042]
In addition, the period during which a guest ID can be transmitted and received must be kept as short as possible so that a person who needs a small number of guest lines can be used temporarily. It's actually difficult to use it, but it's harder to secure it all day. Therefore, a method of uniformly deleting the guest ID at night every day at least is adopted. However, there are cases in which the guest needs to use the mobile terminal for many days for continuous work.
[0043]
In order to recognize these special circumstances as special cases, it is possible to apply to the guest number manager for a procedure for changing the regulation value for extending the validity period and expanding the connection range. In the flow chart of FIG. 7, in step S71, the guest number manager dials the guest management special number from the terminal at his / her seat.
[0044]
In step S72, the password of the operator is confirmed to confirm that the operation is performed by the guest administrator. Key input of the guest ID of the target mobile terminal.
First, since the restriction value corresponding to the ID in the guest ID table, that is, the extension period and the connection range are sequentially displayed and notified, the operator inputs a new restriction value from the dial key when there is a change.
[0045]
The new regulation value is notified by voice and display, and confirmed in step S75. Thereafter, the user of the guest mobile terminal applying for the service can use the new mobile terminal according to the new regulation value.
[0046]
Finally, the operation of deleting the guest ID will be described with reference to FIG.
As described above, the user usually does not actively perform an operation that is disadvantageous to him. Therefore, the application for deleting the guest ID of the guest mobile terminal can be performed by dialing the special number, but the guest ID can be deleted. It has no effect. Therefore, the guest ID is mechanically erased once a day at night.
[0047]
As shown in step S81, the clock is started at a fixed time every day by the clock. In step S82, only the extension time limit of the guest ID table is considered, and all the items that have not been extended are deleted from the guest ID table. ing. As a result, it is possible to assign a guest extension number that is newly secured from the next day.
[0048]
In the above embodiment, the registration of the registration ID in the guest ID table of the mobile terminal is automatically performed when the call operation of the normal mobile terminal is performed. The fact that there is a service window may be notified and registered as a guest ID by a separate procedure. That is, there is a method of providing guidance by voice using a talkie device or the like or displaying an inquiry destination telephone number on a display unit of a mobile terminal to provide guidance.
[0049]
【The invention's effect】
As is apparent from the above description, according to the present invention, even for a mobile terminal in which an ID is not registered, an ID is automatically registered as a guest and a guest access number is given as an extension number. Provide means to enable connection to the private branch exchange, such as enabling connection and notifying the assigned access number to the mobile terminal by notifying it to the mobile terminal. There is a significant industrial effect of increasing the efficiency of economic activity for many members of society.
