Abstract

[Problems] To share information in one of divided screens of a terminal device with members performing PoC communications. [Means For Solving Problems] A plurality of terminal devices used by the members performing PoC communications are included, and at least one of the screens partitioned and displayed by a screen dual-partitioning device 22 on a specific terminal device is shared with other terminal devices used by members performing PoC communications.

1 . A terminal device comprising:
 a screen activation unit for partitioning a screen of a mobile terminal into a plurality of screens corresponding to PoC communications and activates the screens; and   a switch selector unit for switching between activated plurality of screens and selects one.   
   
   
       2 . The terminal device according to  claim 1 , wherein the screen activation unit activates the plurality of partitioned screens while keeping them displayed at a time of starting PoC communications. 
   
   
       3 . The terminal device according to  claim 1 , wherein the screen activation unit keeps one of the partitioned screens in an activated state, and at the time of starting PoC communications, a remaining screen of the partitioned screens is activated by interrupting the one screen. 
   
   
       4 . The terminal device according to  claim 1 , wherein the screen activation unit activates a plurality of screens displayed on a mobile terminal held by a member performing the PoC communications on one screen. 
   
   
       5 . The terminal device according to  claim 1 , wherein the screen activation unit reflects a function setting for a screen displayed on a mobile terminal held by a communication counterpart on the screen of a mobile terminal held by a user himself/herself. 
   
   
       6 . The terminal device according to  claim 1 , wherein the screen activation unit includes a rule setting unit, and
 the rule setting unit sets rules of PoC communications.   
   
   
       7 . An information sharing system including a plurality of terminal devices used by members performing PoC communications, wherein at least one of partitioned screens displayed on a predetermined terminal device is shared with another terminal device used by a member performing the PoC communications. 
   
   
       8 . An information sharing system including a plurality of terminal devices used by members performing PoC communications, wherein partitioned screens displayed on a plurality of predetermined terminal devices are shared by being displayed simultaneously with other terminal devices used by the members performing the PoC communications. 
   
   
       9 . The information sharing system according to  claim 7 , wherein the shared screen is operated from the other terminal device. 
   
   
       10 . The information sharing system according to  claim 7 , wherein a function setting on the shared screen is performed by the other terminal device, and the setting is reflected on the predetermined terminal device. 
   
   
       11 . The information sharing system according to  claim 7 , wherein the partitioned screen displayed is switched by a selector switch. 
   
   
       12 . An information sharing method using a plurality of mobile terminals used by members performing PoC communications, comprising:
 partitioning a screen and displaying partitioned screens on a predetermined terminal device; and   sharing at least one of partitioned and displayed screens with another terminal device used by a member performing the PoC communications.   
   
   
       13 . An information sharing method using a plurality of terminal devices used by members performing PoC communications, comprising:
 partitioning each screen and displaying partitioned screens on a plurality of predetermined terminal devices by each of a plurality of predetermined terminal devices; and   sharing the displayed partitioned screens with another terminal device used by a member of the PoC communication by displaying simultaneously.   
   
   
       14 . The information sharing method according to  claim 12 , further comprising operating the shared screen from the other terminal device. 
   
   
       15 . The information sharing method according to  claim 12 , further comprising performing function setting on the shared screen of the other terminal device and reflecting the setting on the predetermined terminal device. 
   
   
       16 . The information sharing method according to  claim 12 , further comprising switching between the partitioned and displayed screens by a selector switch. 
   
   
       17 . A computer readable recording medium storing a program for causing a computer to execute
 a function of partitioning a screen of a mobile terminal into a plurality of screens corresponding to PoC communications and activating the screens, and
 a function of switching between the plurality of activated screens and selecting one. 
   
   
   
       18 . A terminal device comprising:
 a screen activation means for partitioning a screen of a mobile terminal into a plurality of screens corresponding to PoC communications and activates the screens; and   a switch selector means for switching between activated plurality of screens and selects one.
