Description

Telephone terminal device

The present invention relates to a telephone terminal apparatus for making a call via a communication network.

In general, telephony is supposed to enable one-to-one communication, but there is also a small number of demands for multiparty calls.

In the prior art, when a multi-party call is to be realized, a process for that is performed on the network side.

Fig. 11 is a diagram showing a configuration example of a communication system for realizing the function of the multi-party call.

The public network NT101 is constituted by multiplexing a plurality of exchangers (EX: here only one). At least a part of the plurality of exchanges EX has a voice adder MX101 as an additional function.

In the public network NT101, like a wired terminal FS101, a terminal connected directly through a subscriber line, or like a wireless terminal PS101, PS102, PS103, is connected via a base station CS101, CS102, or the like. By arbitrarily switching between terminals, one-to-one communication is possible.

In order to conduct a multiparty call, at least three lines for carrying out a multiparty call are introduced into an exchange EX having a voice adder MX101 as an additional function. The line introduced into the switch EX is passed through the voice adder MX101, which is an add-on function of the switch EX, so that a multi-party call becomes possible.

12 is a diagram showing another configuration example of a communication system for realizing the function of the multi-party call.

In this example, the voice adder MX is provided as an additional function in at least part of the base station CS.

In this system, a terminal connected directly through a subscriber line, such as a wired terminal FS111, or a terminal connected via a base station CS111, CS112, or the like, such as a wireless terminal PS111, PS112, or PS113. The connection is made by the public network NT111.

In order to conduct a multi-party call, at least three lines for carrying out the multi-party call are introduced into the base station CS equipped with the voice adder MX MX 111, for example, as the base station CS111. The line introduced into the base station CS passes through the voice adder MX, which enables a multi-party call.

However, in the case of realizing the function of the conference call by such a configuration, the voice adder must be mounted as an additional function in the existing exchange or base station. Therefore, a lot of equipment investment is required.

In the case of the configuration shown in Fig. 11, in the case of constructing a public network by using a switch which does not have a function of a voice adder in combination with a switch provided with a voice adder, the circuit is connected to a switch having a function of the voice adder by bypassing the line. You must use the adder. Thus, extra switching is needed for the exchange.

On the other hand, in the case of the configuration shown in Fig. 12, for example, two characters in a three-way call can be accommodated in a single base station (with a voice adder). If only one can accommodate, two lines should be used between base station and public network. That is, for example, in the case where the wireless terminals PS111 and PS112 are two characters when making a three-way call, the signal after voice addition can be transmitted between the CS111 and the NT111, but one line may be used. When making a three-way call between the PS113 and the wired terminal FS111, two lines must be used between the base station CS111 and the public network NT111. For this reason, the circuit between the public network and the base station is used extra.

In addition, even in any one of the above configurations, the number of resources of a function for performing voice addition that a facility has is limited, and in the case where a multi-party call has already been made, there is a case that a new multi-party call may not be able to cope with it. have. To avoid this inadequacy, it is necessary to increase the number of functional resources sufficiently, but this requires a huge amount of equipment investment.

As described above, conventionally, a voice addition function is provided at an exchange or a base station to realize a multi-party call function on the network side. Therefore, the configuration becomes large and requires a lot of equipment investment. Therefore, there is an inadequacy such that an extra switching is required, or an excess line is used between the public network and the base station and the efficiency is lowered.

SUMMARY OF THE INVENTION The present invention has been made in view of the above point, and an object thereof is to provide a telephone terminal apparatus which can easily realize a multi-party call using an existing communication network without changing network facilities.
