Description

  The present invention relates to an inboard group call system for communication between departments in a ship.

  In a conventional group call system, a telephone directory database is created in advance, and group call members are called by accessing the database (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 2003-298751

In a conventional group call for inter-department communication by a plurality of people in a ship, the telephone conference function of the exchange is used to hold a conference call every time or repeat one-on-one call.
For this reason, there was a problem that the responsiveness in the communication between departments in an emergency was lacking.

  The present invention has been made to solve the above-described problems, and is capable of participating in a group call for inter-department contact immediately from a telephone terminal by always holding a plurality of group call for inter-department contact in a ship. The purpose is to provide.

  In the inboard group call system according to the present invention, a group call is always held in order to improve responsiveness in an emergency in an inboard group call system that uses an IP exchange and an IP telephone terminal to communicate between departments in the ship. An IP exchange and an IP telephone terminal having group call participation means that enables participation in a group call are provided.

  According to the present invention, there is an effect that a group telephone system for inter-department communication in a ship with improved responsiveness in an emergency can be realized with a simple configuration.

Embodiment 1 FIG.
A first embodiment of the present invention will be described below with reference to FIG. FIG. 1 shows an inboard group call system to which Embodiment 1 of the present invention is applied. An IP exchange 100 having functions of group call # 1 and group call # 2 and an IP telephone terminal 110 for group call # 1 are shown. -114, IP telephone terminals 120-122 for group call # 2, and network 130 connecting them.
FIG. 2 is an example of the operation surface of the IP phone terminal 110 for group call # 1, and a group call participation button 201 is provided.

Next, the operation will be described. The IP exchange 100 always holds a group call # 1 and a group call # 2 for communication between departments.
The IP telephone terminals participating in each group call are determined in advance. For example, the IP telephone terminals 110 to 114 always participate in the group call # 1, and the IP telephone terminals 120 to 122 always participate in the group call # 2.

  Here, when the group call participation button 201 is pressed on the IP phone terminal 110 for group call # 1 shown in FIG. 2, the group call # 1 is automatically joined and immediately with other participants of the group call # 1. Calls can be made.

Embodiment 2. FIG.
In the first embodiment, the case where the group call participation button 201 is used to participate in the group call has been described. However, as shown in FIG. 3, the group member call button 301 is provided and registered in the group call # 1. By making it possible to call an IP telephone terminal that has not participated, it is possible to reliably perform a scheduled group call between IP telephone terminals.

Embodiment 3 FIG.
In the first and second embodiments, the general IP phone terminal is provided with the group call participation button 201 and the group member call button 301. However, if the group call IP phone terminal is a group call, the group call can be performed without pressing the button. Can participate.

Embodiment 4 FIG.
In Embodiments 1 to 3 described above, a group to participate in is assigned to each IP telephone terminal. However, as shown in FIG. 4, the IP telephone terminal has a structure in which a handset (or headset) can be easily attached and detached. In other words, a handset (or headset) 401 having an ID function, in which a handset (or headset) has a group call ID, can be attached to and detached from an IP telephone terminal by a handset attaching / detaching connector 402. Then, the IP telephone terminal can participate in the necessary group conference regardless of the location of the IP telephone terminal by transmitting the group conference number to join based on this ID to the IP exchange. In the figure, reference numeral 403 denotes a group call participation button provided in the IP telephone terminal.

FIG. 5 is a conference participation flowchart of the IP telephone terminal according to the fourth embodiment.
When the IP telephone terminal starts up, it waits for a handset connection (step S1). When the handset is connected, an ID is acquired from the handset (step S2), and the group call waiting button is pressed (step S3). When the group call participation button is pressed, the participation in the conference is notified to the IP exchange based on the ID number acquired in step S2 (step S4), and the group call state is set (step S5).
