If the calling terminal attempts to make a call to the first called terminal before applying for the call forwarding service (S101), the exchange performs a series of called procedures such as obtaining routing information according to the first called terminal number. In operation S103, the paging signal is transmitted to the first destination terminal. If a name matching the calling terminal number is stored in the first called terminal, the first called terminal is output the name according to the calling terminal number stored in the address book and informs the user that the call has been received (S105).

If the calling terminal attempts to make a call to the first called terminal while the first called terminal user transfers the call to the second called terminal (S101), the exchange requests that the first called terminal user apply for the call transfer service. Confirming that the user (S201), and extracts the second destination terminal number to be forwarded (S203). Subsequently, in order to switch the incoming call to the second destination terminal, a series of incoming procedures including a process of obtaining routing information to the second destination terminal and the like are performed to transmit a paging signal to the second destination terminal (S205). The called terminal informs the user of the incoming call (S207). At this time, when the second called terminal is the terminal of the calling number display service subscriber, the calling terminal number will be output to the second called terminal, and if the name matching the calling terminal number is stored in the second called terminal, the corresponding name. Will be output. If the second called terminal is not the terminal of the calling party number service subscriber, only the incoming call will be notified.

Request to synchronize the address book to the address book synchronization server 30, and when the incoming event occurs to the communication terminal of the call forwarding service requester, extracts the communication terminal number to be forwarded, and matches the calling number with the address book synchronization server. Collects the address book information of the communication terminal 10 before the call forwarding in accordance with the request of the communication system 20, the communication system 20 for requesting and receiving a name to be transmitted, and the calling number and the called number are transmitted from the communication system 20 Address book synchronization server that extracts the stored caller name matched to the calling party number, processes it, and sends it to the communication system 20. And a 30.

Here, the communication system 20 may be a mobile communication system or a wired communication system. In the case of a mobile communication system, whether or not the corresponding service is used and communication terminal information to be forwarded is stored in the home location register (HLR) 220 through the switch 210 according to the call forwarding service request. Whether to use the service according to the switch service request and communication terminal information to be forwarded is stored in the call forwarding server 230 through the switch 210.

For example, when the first called terminal user requests the call forwarding service to the second called terminal, the home location register 220 or the call forwarding server 230 may include the call forwarding service usage information of the first called terminal user. The second called terminal number is stored.

When the call forwarding service is requested, the exchange 210 transmits the first destination terminal number to the address book synchronization server 30 to collect address book information. Accordingly, the address book synchronization server 30 is stored in the first destination terminal. Collect and store the phone number and the name information matched with the.

When an incoming event occurs to the first called terminal of the call forwarding service requester, the switch 210 transmits the first called terminal number to the home location register 220 or the called forwarding server 230 to the call forwarding service user. After confirming that the call forwarding event is requested, and accordingly, the home location register 220 or the call forwarding server 230 checks whether the call forwarding service user is referred to by referring to the first called terminal number. The second destination terminal number to transfer the call to the first destination terminal is extracted and provided to the exchange 210.

Accordingly, the exchange 210 transmits the first called terminal number and the calling number to the address book synchronization server 30 to request and receive name information matching the calling number from the address book information collected from the first called terminal. After acquiring the routing path to the second destination terminal, the paging signal is sent along with the caller name information to the second destination terminal.

In this manner, caller name information stored in the address book of the first destination terminal is output to the second destination terminal.

3 is a flowchart illustrating an incoming call switching method according to an embodiment of the present invention. Hereinafter, for convenience of description, the communication terminal before the incoming call transfer will be referred to as a first incoming terminal, and the communication terminal after the incoming call transfer will be referred to as a second incoming terminal.

As the first called terminal user requests the call forwarding service, the exchange 210 stores the call forwarding service related information in the home location register 220 or the call forwarding server 230, and sends it to the address book synchronization server 30. The address book information of the first called terminal is collected (S301).

In this state, as the calling terminal attempts to call the first called terminal (S303), the switch 210 checks whether the called terminal is a call forwarding service using the first called terminal information using the first called terminal information and transfers the call. In the case of the service using terminal, the second called terminal number to be forwarded is extracted (S305).

In addition, the exchange 210 requests the name of the caller by transmitting the first called terminal number and the calling terminal number to the address book synchronization server 30 (S307), and accordingly, the address book synchronization server 30 collects the first collected terminal number. 1 Referring to the address book information of the called terminal, the name of the caller matching the corresponding calling terminal number is inquired (S309), processed into a form that can be transmitted through a communication network (S311), and transmitted to the exchange 210 (S313). ).

After receiving the sender's address book name, the exchange 210 obtains routing information to the second destination terminal, and then transmits a paging signal including the address book name of the sender to the second destination terminal (S315), and accordingly, the second destination terminal. The called terminal outputs the first called terminal address book name of the caller received from the switch 210 together with the incoming fact (S317).

According to the present invention, when a call forwarded to a second called terminal is received, an address book name stored in the first called terminal which is a call forwarding terminal can be outputted so that the call forwarding service subscriber can easily identify the caller. Of course, it is possible to distinguish whether the call is a call forwarded call or a call directly received by the second destination terminal.
