The interface unit 14 is configured to include a home page database 15 that stores screen information to be displayed on the screen of the terminal 4 when connected from the terminal 4, and an input unit 16 for inputting information.
[0021]
The control unit 11 includes an information collection module 111, a transfer destination determination module 112, and a transfer instruction module 113.
[0022]
The information collection module 111 makes an inquiry about empty port information to each access server 2 periodically (every preset time: due to timer interruption by the timer 12), and the empty information of each access server 2 collected by the inquiry is obtained. The port information is accumulated in a provider access point management table 131 (described later) in the storage unit 13.
[0023]
The transfer destination determination module 112 analyzes the vacant port information of each access server 2 collected by the information collection module 111 to detect the access server 2 having insufficient vacant ports, and each exchange 3 is located at which exchange 3 It is determined by creating an access point transfer destination table 133 (described later) in the storage unit 13 whether the connection from the terminal 4 can be made until the call is transferred.
[0024]
The transfer instruction module 113 divides the access point transfer destination table 133 in the storage unit 13 for each exchange that accommodates the destination access point in response to a request from the transfer destination determination module 112, and divides the access point into the corresponding exchange 3. By sending the table, it is instructed to which exchange 3 to transfer or to cancel the transfer request.
[0025]

That is, referring to FIG. 4, the user access point management table 132 is managed for each user identification name, and is addressed to the user identification name, the user telephone number indicating the transmission source, the registered telephone number for accessing the access point, and the registered telephone number. It includes information on priority indicating the priority order to be connected and information on shortage of empty ports indicating lack of each port of each access server 2. The empty port shortage is blank at the time of initial setting. The priority is higher as the number is lower, and “1” indicates the highest priority. Further, the priority “1” indicates an access point during normal use.
[0028]
The home page database 15 is allocated in advance to an area in a nonvolatile recording medium device (for example, a magnetic disk device).
[0029]
In the access point transfer destination table 133, the empty port information (provider access point management table 131) and user information (user access point management table 132) collected by the port monitoring module 111 are analyzed and analyzed by the transfer destination determination module 112. The result is registered in the area of the storage unit 13. That is, referring to FIG. 5, the access point transfer destination table 133 is managed for each transmission source telephone number (user telephone number) and includes each information of the transmission source telephone number, the destination telephone number, and the transfer destination telephone number.

The number of empty ports in the storage unit 25 stores the maximum number of empty ports at the time of initial setting (when the system is started up).
[0031]
The control unit 21 monitors an empty port in the line unit 23 of the access server 2, stores the result in the storage unit 25, and further reads out the empty port information from the storage unit 25 in response to a request from the connection control device 11. An empty port monitoring module 211 for notifying the control device 1 is included.
[0032]
The exchange 3 includes a control unit 31 that operates under program control by a processor (not shown), a storage unit 32 that can be read and written, an interface unit 33 that communicates with the network 200, a call control unit 34 that performs call control, The switch unit 35 is configured to switch the electronic exchange switch based on the call control unit 34, the line unit 36 for exchanging with the line network 61, and the line unit 37 for exchanging with the line networks 62 and 300. The
[0033]
The control unit 31 includes a call change control module 311 that performs a process of transferring a call to an access point (call setting) to another access point or canceling the transfer in response to a transfer destination change request from the connection control device 1. including.
[0034]
The storage unit 32 allocates an area of the access point transfer destination table 321 that manages transfer destinations that access the access points.
[0035]
The access point transfer destination table 321 is sent from the connection control device 1 when the access point access destination changes, and is overwritten (registered) in the area of the storage unit 32 by the control unit 31. That is, referring to FIG. 6, the access point transfer destination table 321 is managed for each transmission source telephone number (user telephone number) under the exchange 3, and each information of the transmission source telephone number, the destination telephone number, and the transfer destination telephone number is stored. including.
[0036]
Next, the operation of the embodiment of the present invention will be described with reference to FIGS. 1 to 7 and FIG.
First, when there is a connection request (call setting) from the user of the terminal 4 of the Internet connection request to the exchange 3-A via the network 61, the control unit 31 that has received the call setting via the line unit 36 The access point transfer destination table 321 in the storage unit 32 is searched based on the source telephone number and the destination telephone number extracted from the call setting after checking, and if there is a match (registered), the access point transfer It is checked whether the transfer destination telephone number is registered in the transfer destination telephone number column of the destination table 321. If registered, the control unit 31 replaces the destination telephone number in the call setting with the transfer destination telephone number registered in the transfer destination telephone number column of the access point transfer destination table 321, and controls the call control unit 34. The operation is finished by passing (steps S31 to S36 in FIG. 9).
[0037]
In this case, the call control unit 34 having received the control issues a switching instruction to the switch unit 35 from the destination telephone number received from the control unit 31 (in order to establish a path from the line unit 36 to the port in the corresponding line unit 37). 2), the call setting after changing the destination is transmitted to the exchange 3 under the management of the destination telephone number (accommodating the destination telephone number) via the line unit 37 and the line network 300. That is, when the access server after changing the address is 2-B, the changed call setting is transmitted to the exchange 3-B via the network 300. The call control unit 34 of the exchange 3-B that has received the call setting via the line unit 37 performs switching for the switch unit 35 and performs the call setting via the line unit 37 and the line network 62. Send to. When the control unit 21 of the access server 2-B that has received the call setting via the port in the line unit 23 returns a response to the call setting, a communication path is set between the terminal 4 and the access server 2-B. The Rukoto. Further, after returning a response, the control unit 21 passes control to the empty port module 211, and the empty port monitoring module 211 to which the control is passed subtracts 1 from the number of empty ports in the storage unit 25 (see FIG. 7 steps S21, S23).
[0038]
Eventually, when the communication path is disconnected, the empty port monitoring module 211 adds 1 to the number of empty ports in the storage unit 25 (steps S21 and S24).
[0039]
In this way, the empty port monitoring module 211 of the control unit 21 of the access server 2 increases or decreases the number of empty ports in the storage unit 25 every time an incoming call, call origination, or disconnection occurs. Is stored in the storage unit 25, so that an empty port can always be monitored. When the number of empty ports becomes 1, when there is a request for collecting empty port information from the connection control device 1 via the interface unit 22, the control unit 21 analyzes the cause and stores the empty port information. 25, and the read information (including information on the number of empty ports being “1”) is transmitted to the connection control device 1 (steps S21 and S22).
[0040]
On the other hand, a value is set in the timer 12 of the connection control device 1 so that an interrupt is generated at a preset time, and this interrupt is generated to the control unit 11 at regular intervals. When this timer interrupt occurs, the control unit 11 passes control to the information collection module 111. The information collection module 111 to which control has been passed sends a query for empty port information to all IP addresses registered in the IP address column of the provider access point management table 131 of the storage unit 13 (to all access servers 2). 200. In this way, the information collection module 111 stores the number of empty ports received from each access server 2 in the processes of steps S21 and S22 in the corresponding empty port number area of the provider access point management table 131, and determines whether to transfer control. Pass to module 112. At this time, 1 is set as the number of empty ports corresponding to the access server 2-B (steps S11 to S12).
[0041]
Next, the transfer destination determination module 112 of the control unit 11 to which control is given searches the provider access point management table 131 to determine whether or not the number of empty ports is equal to or less than a predetermined value (for example, 1). If it is equal to or less than the value, “1” indicating a shortage is stored in the empty port shortage area corresponding to the registered telephone number of the user access point management table 132. Accordingly, “1” is set in the empty port shortage area of the user 4-A- having the telephone number of the access server 4-A (access point identification name 4-A). Further, the transfer destination determination module 112 searches the empty port shortage column of the user access point management table 132 of the storage unit 13 and when it is “1” and the priority column is “1”, the user telephone of the user The number and the registered telephone number of the priority “2” are read out and registered in the access point transfer destination table 133 (the registered telephone number of the priority field “1” is registered in the destination telephone number field, and the registered telephone number of the priority “2”). In the forwarding phone number field). In this case, even if the shortage of empty ports is “1”, the transfer destination determination module 112 does nothing if a registered telephone number having a higher priority than a registered telephone number that has a shortage of empty ports is not short of empty ports. If there is a plurality of priorities, the transfer destination determination module 112 reads the registered telephone number corresponding to the next priority and registers it in the access point transfer destination table 133. If all the registered priorities are insufficient for empty ports, the transfer destination determination module 112 stores a blank in the destination telephone number column of the corresponding transmission source telephone number. This blank means that there is no transfer number when calling from the corresponding transmission source telephone number to the exchange 3, which means that the transfer request is canceled. When the search is completed, the transfer destination determination module 132 passes control to the transfer destination instruction module 113 (steps S13 and S14).
[0042]
The transfer destination instruction module 113 of the control unit 11 to which the control is passed divides the access point transfer destination table 133 of the storage unit 13 into subordinate units (for each accommodated area) of each exchange 3, and the divided access point transfer The destination table 133 is transmitted to each corresponding exchange 3. After the transmission, the transfer destination instruction module 113 clears the data in the empty port shortage column of the user access point management table 132 in the storage unit 13 and deletes the data in the access point transfer destination table 133 (steps S15 and S16).
[0043]
In this way, the operation of the flowchart shown in FIG. 9 described first is performed. If it is not registered in Step S34 (when the forwarding telephone number field is blank), the control unit 32 requests the call control unit 34 to cancel the call setting and ends the operation (Step S37). In this case, the call control unit 34 that has received the request performs call setting cancellation processing.
[0044]
Next, a case where the user terminal 4 registers in the user access point management table 132 of the storage unit 13 of the connection control device 1 will be described.
[0045]
First, the user starts up a browser on the terminal 4, connects the terminal 4 to the access server 2 of the provider with which the user has a contract, and then connects the terminal 4 to the connection control device 1 using a URL (Uniform Resource Locator) (terminal) 4 and the connection control device 1 are set up a communication path).
[0046]
The controller 11 of the connected connection control device 1 reads the menu screen information (the menu includes an access point registration request) from the home page database 15 and displays it on the screen of the terminal 4. When the user selects an access point registration request according to the display screen, the selected information is transmitted from the terminal 4 to the connection control device 1. The control unit 11 received via the interface unit 14 reads the access point registration screen information from the home page database 15 and transmits it to the terminal 4 to display the access point registration screen on the screen of the terminal 4. When the user enters personal information such as user phone number (source phone number), registered phone number (forwarding destination phone number when empty port is insufficient), priority for registered phone number, etc., which are necessary information according to the screen, entered The personal information is transmitted to the connection control device 1. The control unit 11 of the connection control device 1 that has received the personal information via the interface unit 14 stores the user telephone number, the user telephone number, Register registered telephone numbers and priorities for registered telephone numbers.
[0047]
Therefore, even when the port of the access point to be connected is insufficient, the user does not connect to an unintended Internet access point and can connect to the desired Internet access point registered by the user according to the priority order.
[0048]
As described above, before the restriction on the number of ports of the access server 2 is made, the exchange 3 grasps the access server 2 having insufficient empty ports from the access point transfer destination table 321 and transfers it to the access server 2 having the empty ports. Therefore, users who use the Internet can use the user with a single connection operation (access points that the user is willing to connect to) without being denied access due to lack of access point resources. You can connect to an access point.
[0049]
Further, before the restriction on the number of ports of the access server 2 is made, the exchange 3 grasps the access server 2 having insufficient empty ports from the access point transfer destination table 321 and transfers it to the access server 2 having the empty ports. Therefore, it is possible to reduce useless connection processing on the exchange side, to distribute the effective use of the line on the exchange network, and the concentration of one place of calls, and to equalize the line traffic.
[0050]
Next, the operation described above will be briefly described with reference to the sequence diagram of FIG.
First, when there is a connection request (call setting) from the user 1 of the terminal 4 of the Internet connection request to the exchange 3-A via the network 61, the control unit 31 of the exchange 3-A sets the telephone number of the transmission source. Based on this, it is determined whether the destination telephone number is an access server for the forwarding destination, and if the incoming call is to the access server for which the forwarding destination is to be changed, the local station (local exchange: switch 3-A) is connected. Whether to make an incoming call to the access server or transfer to another station (exchange 3 other than the exchange 3-A) is performed according to an instruction from the connection control device 1. In this case, when there is no shortage of empty ports in the exchange 3-A when the user 1 requests connection, the access server 2-B is connected to the transfer destination by transferring the call as it is to the exchange 3-B station. The communication path is set between the terminal 4 and the access server 2-B (sequence K1).
[0051]
In the access server 2-B, an empty port monitoring module 211 that always counts empty ports is operating, and in response to a periodic inquiry of empty port information from the information collection module 111 of the connection control device 1, empty port information. (In this case, it is assumed that there is a shortage of empty ports). The transfer destination determination module 112 analyzes the access server 2 with insufficient empty ports detected based on the information collected by the information collection module 111 and the available access server information, and transfers the call of the switch 3-A to which switch. The transfer destination information indicating whether or not the transfer should be performed is output to the transfer instruction module 113. The transfer instruction module 113 that receives the control instructs the exchange 3-A to make a call transfer request (request by notifying the transfer destination telephone number) to the exchange 3-B based on the transfer destination information. (Sequence K2).
[0052]
When the user 2 accommodated in the exchange 3-A accesses the access server 2-A using the terminal 4, the call is transferred to the access server B accommodated in the exchange 3-B by the exchange 3-A, and accesses the terminal 4 A communication path is set up with server 2-B (sequence K3).
[0053]
Therefore, the user 2 accommodated in the exchange 3-A can receive the call to the access server 2-B on the exchange 3-B side even if he / she intends to make a call to the access server of the exchange 3-A, and the access server 2-A has insufficient free ports. You can automatically connect to the Internet when you are.
[0054]
As described above, when the Internet user 2 in FIG. 2 tries to make an incoming call to the access server A connected to the exchange A, the exchange A connects to the access server connected to the exchange B according to an instruction from the connection control device. Therefore, the call from the user 2 is transferred to the exchange B. As a result, the user 2 can connect to the Internet with a single connection operation without changing the telephone number of the access point even when there is no free port of the access server A.
[0055]
Next, the case where the access server is maintained will be described with reference to the drawings. During maintenance of the access server, while the maintenance person regularly maintains the access server, the call of the Internet connection request connected to the access server forcibly maintained is diverted to connect to another access server. It is also possible. In this regard, compared with the above-described FIG. 1 to FIG. 7 and FIG. 9, the connection control device 1 changed the telephone number of the transfer destination access server 2 based on the collection of empty port information from the access server 2. Is different in that the empty port is forcibly shorted by inputting the telephone number of the access server 2 that is not desired to be accessed from the input unit 16 (for example, keyboard) of the connection device 1 itself.
[0056]
That is, referring to FIG. 9, when the telephone number of the access server 2 indicating the shortage of empty ports is input from the input unit 16 of the connection control device 1, the control unit 11 stores the storage unit 13 based on the input telephone number. The user access point management table 132 is searched, and if the input telephone number matches the telephone number registered in the telephone number column of the table, 1 is registered in the empty port shortage column corresponding to the matched telephone number. Further, the transfer destination determination module 112 searches the empty port shortage column of the user access point management table 132 of the storage unit 13 and when it is “1” and the priority column is “1”, the user telephone of the user The number and the registered telephone number with the priority “2” are read out and registered in the access point transfer destination table 133. In this manner, when the access point transfer destination table 133 is created, control is transferred to the transfer instruction module 113. That is, the process jumps to step S15 in FIG. Subsequent operations of the connection control device 1 and the operation of the exchange 3 are the same as the operations described above, and a description thereof will be omitted.
[0057]
As described above, also in maintenance, by setting a shortage of empty ports of the access server 2 to be forcibly maintained, it is possible to bypass the transfer destination access server desired by the user.
[0058]
【The invention's effect】
As described above, according to the present invention, since the exchange recognizes an access server having a shortage of empty ports and transfers it to an access server having an empty port before being restricted in the number of ports of the access server, it can be used on the Internet. In an urban area where there are many users, there is an effect that the user of the provider contract can connect to the Internet at any time without being limited by the number of ports of the installed access server at one access point of each provider.
[0059]
In addition, according to the present invention, before the restriction on the number of ports of the access server, the exchange grasps the access server having a shortage of empty ports and forwards it to the access server having the empty port. The user cannot connect even during the time period, so there is no repeated connection request call, the circuit switch side does not increase the traffic volume of incomplete calls, and wasteful use of resources does not occur In addition, it is possible to suppress the traffic of incomplete calls and to effectively use the resources of the exchange side and the access server.
