However, the user must select the service type in a short time because the call forwarding must be requested within 30 seconds after receiving the call. The problem to be solved by the conventional method for requesting call forwarding is that, as mentioned above, the user had to select and specify the type of call forwarding service for each call from among the four types of services. The purpose of the present invention is to provide a device that allows a user to select a service type according to the user's wishes and request call transfer without the user having to perform the task of selecting a service type when requesting call transfer. Means for Solving the Problems of the Present Invention GEL To achieve the above-mentioned object, there is provided a condition setting unit for registering conditions for selecting a service type for call forwarding that are set in advance from the outside, and a call setting unit for incoming calls. a call setting information storage unit that stores information included in the message;
A service selection unit that selects a service type for call transfer based on the conditions set in the condition setting unit, the information stored in the call setting information storage unit, and the information included in the call transfer request set by the user. l5DN characterized by
Function of the Terminal Device The terminal device of the present invention has the above-described structure, so that the user sets conditions in advance in the condition setting section that serve as a reference for selecting the service type of call transfer.

When an incoming call is subsequently received, the information included in the call setting message of the incoming call that is necessary for selecting the service type of call transfer is stored in the call setting information storage section. When a call transfer request is made by a user for an incoming call, the service selection unit selects the information regarding the call to be transferred stored in the call setting information storage unit and the information included in the call transfer request set by the user. 4. A call transfer request message including the selected service type is sent to request the communication network to transfer the call. As described above, it becomes possible to request call transfer according to the user's intention without the user having to select the service type for call transfer.

Embodiment Hereinafter, one embodiment of the terminal device of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of the terminal device in one embodiment of the present invention. Figure East: The communication terminal device 10 includes a condition setting unit 11 that registers conditions for selecting a service type for call forwarding set from the outside, a call setting information storage unit 12 that stores information included in a call setting message when receiving a call, and a call setting information storage unit 12 that stores information included in a call setting message when receiving a call. A service selection unit 13 that selects a service type when requesting transfer, and a sent message processing unit 1 that processes messages sent from users.
4. It is composed of a received message processing section 15 that processes messages received from the communication network, and a communication processing section 16 that exchanges messages with the communication network and performs protocol processing.

The operation of the terminal device of this embodiment configured as described above will be explained below. (2) When a call setting message is received from the communication network, the communication processing section 16 performs protocol processing for the incoming call. The call setting message is passed to the received message processing unit 15 (3) When the received message processing unit 15 recognizes that the call setting message has been received, the receiver analyzes the information elements contained in the message. The information necessary for selecting the service type of call transfer is extracted and stored in the call setting information storage unit 12 in association with the call identification information (4) The call setting message is notified to the user (4)
When a user requests call forwarding in response to a call setup notification, the call forwarding request is first sent to the outgoing message processing unit 14.
passed to. When the outgoing message processing unit 14 recognizes that the message passed from the user is a request for call transfer, it passes the call identification information and transfer destination number included in the request message to the service selection unit 13.

(6) The service selection unit 13 searches the information registered in the call setting information storage unit 12 using the call identification information and retrieves the matching information. The information included in the request message passed from the outgoing message processing unit 14 is compared with the information set in the condition setting unit 11, and if there is a match, the service type of call forwarding set in association with the condition is determined. The selected service type is passed to the outgoing message processing section 14.

(8) The outgoing message processing unit creates a call transfer request message including the passed service type, and the communication processing unit 16
pass it on to

(9) The communication processing unit 16 performs predetermined protocol processing and sends a call transfer request message to the communication network.Concrete condition settings and call transfer services in the terminal device of this embodiment, which operates as described above. The operation for selecting the type will be described next.
