Abstract

PURPOSE:To allow the telephone set to implement such processing as start/release of additional service, selection of communication destination and release (interruption) of a call by relating a communication state to a communication opposite party to a start state of the ISDN additional service with each other in the telephone set to use on specific code number to select plural code numbers. CONSTITUTION:In order to make dialing to a destination 2 according to the three-party conference (changeover mode) from the state, e.g. of the communication between this telephone set A and a destination 1, a code number 49 is entered by depressing an f.3 button 3c with the specific code number registered thereto and an INFO (additional information whose feature identifier is set to 49) message is sent. An exchange returns a message holding the destination 1 and allowing the dialing to the destination 2 and a message representing the start of the changeover mode. The state of each memory of this telephone set A is set as memory B = network holding, memory C=DT (dialing enable), memory K=49 and memory S=2. The code number is decided automatically with a simple operation such as the entry of the specific code number and the need of discriminating the code number for talker changeover is not called for the user.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an ISDN telephone that improves operability when connecting to an ISDN line and using an ISDN additional service (flex phone) function. It is.

[Conventional technology] ISDN additional services are activated using INFO (additional information).
This is done by placing a feature identifier number based on the service request code number on the message and sending it to the exchange.

As a means of giving this service request code number, fixed service request data is given by pressing a button corresponding to each service type in the method on the man-machine interface.

Method, Method■: Enter the numerical value related to the service type using the dial button, etc.

etc. have traditionally been used.

[1lli that the invention attempts to solve: 1 but the method■
In this case, a button with a service request code number assigned to each service type is required, and the user has to judge the current service type and activation status of additional services and use them properly, and in order to realize multiple services, As a large number of buttons are arranged, the external size becomes large.

Further, in method (2), a problem arises in that it is difficult for the user to understand the correspondence between service types and numerical values related to the service types.

Furthermore, these operations are dedicated to activating ISDN supplementary services, and switching communication partners and disconnecting calls require separate procedures, which is inconvenient.

[Means for Solving the Problems] In the present invention, as a means for solving the above-mentioned problems, by associating the communication status with the communication partner and the activation status of the ISDN supplementary service within the telephone, multiple Switch code numbers and start additional services! '! II/Cancel, switch communication partner, release call (
We have realized functions such as OFF FLFi).

The procedure for starting this operation from the man-machine interface is the specific code number according to the present invention.

[Function] In the present invention, with this specific code numbering, among the engineering SDN additional service functions, the following functions are achieved: Function ■: As code number = 49, calling activation, cancellation, and switching of communication partner of Tripartite Association 1 (switching mode) , Action ■: As code number = 51, call waiting response activation, switching of communication partner, Action ■: As code number = 53, cancel champion meeting lIM (mixed mode), Action ■: As code number = 55, communication Cancellation of medium transfer, Effect ■: Switching the communication partner in trilateral meeting l1l (mixed mode) with code number = 58, Effect ■: Switching the communication partner in transfer during communication, with code number = 59, Effect ■: Above I End of operation while SDN additional service is activated
IR function, function ■: Call release function when interrupted while the ISDN supplementary service is activated, six types of code numbers and two types of call disconnection/release functions were realized.

These operations have the meaning of "speaker switching" such as attempting to connect to a new communication partner or returning to the original communication partner, and the input of a specific code number according to the present invention in various communication states. The ability to automatically determine the code number with a simple operation eliminates the need for the user to determine the code number for switching speakers, and furthermore, by assigning this specific code number to a single button, additional services can be activated. We were able to reduce the number of buttons for
