[0006]

According to the present invention, subscriber information of a subscriber who has not subscribed to a communication network can also be stored in a location register of the communication network, so that the switching center can perform transmission processing. When the subscriber accesses the location register of the communication network and retrieves the subscriber information of the subscriber, if the subscriber information does not exist, the subscriber accesses the location register of the communication network to which the subscriber first subscribes. Then, it obtains the subscriber information of the subscriber and performs a calling process.

[0007]

FIG. 1 shows a configuration example of a communication system to which the present invention is applied, and the same reference numerals are given to portions corresponding to those in FIG. In each communication network 1 _1, 1 ₂ in this invention, are to be stored in location register the subscriber information of the subscriber is not a member to the communication network. Therefore, FIG.
In the communication network 1 _1, 1 _2, respectively Visitor Location Register 5 _1, 5 ₂ are provided, it is adapted to store subscriber information of the subscriber that this does not subscribe to the communication network. The location registers 4 ₁ and 4 ₂ that store the subscriber information of the subscribers subscribing to the communication network are called home location registers.

[0008] Visitor location register 5
₁ (5 _2), as shown in FIG. 2, the mobile switching center 2 ₁ of the communication network 1 _{1, 2} 2 (2 _3, 2 ₄₎ and other communication network 1 ₂ (1
₁ ) Signaling device 6 for accommodating a control line between home location register 4 ₂ (4 ₁ ) and communication network 1
₁ Another communication network 1 that is registering an incoming call to a terminal in (1 ₂ ).
₂ A subscriber memory 7 for storing the subscriber information of the subscriber subscribing to (1 ₁ ), and an address memory for storing an address of a home location register for constantly storing the subscriber information for each subscriber. 8 and a control device 9 for controlling each part.

[0009] visitor when a registration request subscriber that subscribes to the communication network 1 ₂ is a receiving terminal to terminal 3 ₁ of another communication network 1 ₁ at terminal 3 _1, switching center 2 ₁ that the and notifies the location register 5 _1. Since the visitor location register 5 ₁ subscriber information of the subscriber is not present in the subscriber memory 7, the subscriber's home location register, i.e. home location register of the communication network 1 ₂ to which the subscriber subscribes 4 ₂ the subscriber information from the requesting to transfer the visitor location register 5 ₁ is stored in the subscriber memory 7 subscriber information the transfer.

[0010] In this configuration, subscriber has contracted to receive a personal communication service in any of the communication network 1 _1, 1 ₂ is the outgoing call can be another communication network of the communication network that subscribes You. The transmission control sequence is shown in FIG. 3, and the operation of the control device 9 is shown in FIG. 1 to 4
