摘要： PURPOSE: To connect to a desired VPN called party without redialing by a VPN caller and without notifying a moving destination of an absent party. CONSTITUTION: Connection destination revision is controlled to connect a member's net service of a virtual private network(VPN) β with respect to a specific subscriber set connecting to a public communication network including subscriber exchanges 1, 2, 3 through a common line signal network 5. In this case, a VPN subscriber dependent schedule management table 11 is prepared in advance for a network service control station 6 and when an inquiry about the connection of a VPN subscriber receiving the member's net service is received, the schedule management table 11 is used to retrieve a subscriber ID (VPN or general subscriber ID) being a connection destination of the called VPN subscriber corresponding to a current point of time and the called VPN subscriber C2 is connected to the communication network by using the subscriber ID.

摘要： PURPOSE: To make it possible to connect also a terminal which is not provided with an abbreviated number dialing function to a specific subscriber inside or outside a VPN by one dial input or a dial input of two or three digits. CONSTITUTION: When a call originating VPN subscriber inputs a specific number, the general subscriber's ID of the VPN subscriber and a specific number signal are received through a common line signal network 4 and a registered ID corresponding to the general subscriber's ID of the VPN subscriber is retrieved by a VPN-sorted general subscriber's ID/registered ID collating table 11 stored in a network service control station 5. Then the general subscriber's ID of an incoming subscriber corresponding to the registered ID is retrieved by a VPN-sorted VPN subscriber's ID/general subscriber's ID collating table 10 and a communication network is controlled to be connected to the incoming subscriber based upon the general subscriber's ID.

摘要： PROBLEM TO BE SOLVED: To avoid poor economy in the short-distance communication of selective combination connection of communication networks between a national or short- distance local communication enterpriser and a newly participated long-distance local communication enterpriser. SOLUTION: The dial signal of an originated call is received (ST1). It is judged whether the originated call is a connected call designating a 2nd communication eterpriser NCCT or not (ST2) and in the case of judgement of NO, the communication is guided (ST3) to ordinary call connecting processing (ST8) for fully opening the communication network of the 1st communication enterpriser. In the case of judgement of YES, call connecting processing due to an address message is performed to the 2nd communication enterpriser designated by the originated call (ST4). It is judged whether a reconnect signal is returned from the communication network of the 2nd communication enterpriser or not (ST5). When absence is judged, call connecting processing to the communication network of the 2nd communication entrepreneur is continued (ST6). When presence is judged, reconnecting processing due to an incoming number parameter is performed by a call originating side subscriber exchange LS (ST7) and ordinary call connecting processing is performed inside the communication network of the 1st communication enterpriser (ST8).

摘要： PURPOSE: To provide an extension connection method/system device between a domestic virtual exclusive network and an international virtual exclusive network in order to perform the international communication by means of an international VPN extension number without switching the domestic virtual exclusive network to an off-net state from an on-net state. CONSTITUTION: When the dial number that is dialed by a domestic VPN contract subscriber A is equal to an international VPN extension number, a domestic network service control station 4 extracts a location number out of the international VPN extension number. Then the station 4 retrieves a prefix corresponding to the extracted location number out of an international extension connection data table 13 and gives an instruction to a domestic subscriber exchange 1 through a common line signal network 3 to connect the domestic virtual exclusive network to the international virtual exclusive network by means of a routing number including the prefix added to the international VPN extension number.

摘要： PURPOSE: To attain the flexible setting of numbers and a flexible outgoing operation by freely forming a series of communication channels passing through the mutual connection point between a public electrical communication network and a mobile object network based on a connection control signal. CONSTITUTION: A VAN subscriber A dials the identification number of a mobile terminal 6. When a control part 10 of a network service control station 4 decides the dialed number as an extension number, the part 10 retrieves a table to read out a mobile subscriber ID corresponding to the terminal 6 in response to the identification number. Thus the mobile subscriber ID corresponding to the dialed identification number is read out and this identification number is translated into a physical number of the subscriber ID. Then the physical number is sent to a SAP part 11 of an ordinary exchange 1 of the subscriber A. The part 11 receives a routing number from the part 10 and is connected to a mobile exchange 9 including a terminal 6 via a communication channel 15. When a response is received from the terminal 6, the subscriber A can perform its communication such the calling, etc.

摘要： PURPOSE: To obtain an incoming call screening method and device for a virtual private network which can allow the connection of only an incoming request from a specific subscriber or a specific subscriber's terminal. CONSTITUTION: General subscriber's ID, VPN subscriber's ID allowed to pass in a subscriber's group of the same member network and a data base to which password information is allowed to correspond are previously prepared. When connection to a subscriber to which a member newtwork service is given is requested from subscriber's switchboards 1, 2, a password sent from a call originating subscriber is collated with the password of an incoming subscriber based upon a data base stored in a service control station 5. Only at the time of coincidence between both passwords, a public electric communication network is connected to the incoming subscriber concerned through a common line signal network 4.
