• a service control device with entry capabilities for communicating with the communications device in a predetermined procedure and entering in a data base, as associating with a predetermined number in the second number system, the predetermined number in the first number system assigned to the communications device obtained by the communicating with the communications device;
• and
• an exchange for accommodating a station line connected to the first communication in the network and an extension in the fourth communications network.

A communications system connected to a public network in a first number system and a private network in a second number system, comprising:

• a first communications device connected to the public network and assigned a first user number in the first number system;
• a service control device with entry capabilities comprising:
• identification information requesting means for prompting said first communications device for user identification information of a user of said first communications device when said identification information requesting means receives a predetermined special number from said first communications device;
• confirming means for receiving the user identification information and checking whether or not the user identification information is preliminarily entered;
• user number requesting means for prompting the user for a user number when said confirming means confirms that the user identification information is preliminarily entered;
• and
• entering means for receiving the first user number, assigning a first extension number in the second number system to said first communications device, and entering in a data base the first extension number as being associated with the first user number;
• and
• a local exchange for accommodating a station line connected to the public network and an extension in the private network.

A communications system connected to a public network in a first number system and a private network in a second number system, comprising:

• a first communications device connected to the public network and assigned a first user number in the first number system;
• a service control device with entry capabilities for communicating with the first communications device in a predetermined procedure and entering in a data base, as associating with a first extension number in the second number system, the first user number in the first number system assigned to the first communications device obtained by the communicating with the communications device;
• and
• a local exchange for accommodating a station line connected to the public network and an extension in the private network.

A communications system connected to a public network in a first number system and a private network in a fourth number system, comprising:

• first and fourth communications devices connected to the public network and assigned first and fourth user numbers respectively in a first number system;
• and
• a service control device with entry capabilities for communicating with the first communications device in a predetermined procedure, entering in a data base the first user number as being associated with a first extension number in the second number system, likewise communicating with the second communications device in a predetermined procedure, entering in the data base the second user number as being associated with a second extension number in the fourth number system, wherein
• if the first communications device issues the second extension number, then the service control device receives the second extension number through the public network, extracts the second user number by referring to the data base according to the second extension number, and controls the public network to call the second communications device using the second user number.

A communications device entry method applied to a communications system having a first exchange for accommodating a centralized extension service subscriber grouped according to predetermined centralized extension service identification information, a local Service Control Point (SCP), connected to the first exchange, for managing the centralized extension service, a network SCP connected to the first exchange through a network, and a second exchange connected to the network, comprising the steps of:

• sending to the fist exchange a service activate request from an optional communications device;
• notifying the network SCP from the first exchange via the network of a predetermined number for entry corresponding to the service activate request and an identification number of the optional communications device to be accommodated by the second exchange;
• notifying by the network SCP the local SCP of entry request information and the identification number of the communications device;
• requesting by the local SCP, in response to a notification from the network SCP, to the communications device for the centralized extension service identification information and information identifying a user who sent the service activate request through the communications device;
• sending, in response to a request from the local SCP, from the communications device to the local SCP the centralized extension service identification information and the information identifying the user;
• and
• determining by the local SCP the centralized extension service to be provided for the communications device according to the centralized extension service identification information or the information identifying the user received from the communications device.

• sending to the second exchange a service activate request from an optional communications device;
• notifying by the fourth exchange via the network the network SCP of a predetermined number for entry corresponding to the service activate request and an identification number of the optional communications device;
• requesting by the network SCP the communications device to enter centralized extension service identification information and information identifying a user who sent the service activate request from the communications device;
• sending the centralized extension service identification information and the user identification information from the communications device to the network SCP;
• and
• determining by the network SCP a centralized extension service to be provided for the communications device according to the centralized extension service identification information or the user identification information received from the communications device.
