Abstract
A system allows prompt multimedia data transfer during communication between personal telephones through a dedicated line connecting PBXs. A database connected to each PBX stores association information between a personal telephone and a personal computer. When a multimedia application installed in one personal computer associated to one personal telephone starts up, another multimedia application installed in the other personal computer associated to the other personal telephone automatically starts up allowing multimedia data communicate with each other.
Claims10
A system for transferring multimedia data between processes generated by software programs each running on information processing terminals, wherein the information processing terminals are capable to communicate with each other through at least one call connection controller that accommodates a plurality of extension terminals, wherein
- each call connection controller comprises:
- a database for storing association information when an association operation has been performed between an extension terminal and an information processing terminal, which are both connected to the call connection controller;
- a determining section for determining the presence or absence of an information processing terminal that has completed the association operation and a status of a software program on the information processing terminal;
- and
- a communications controller controlling such that, during communication between a first extension terminal and a second extension terminal, when first and second information processing terminals that have completed the association operations with the first and second extension terminals have been found and both of software programs on the first and second information processing terminals are ready and currently unused, multimedia data starts transferring between processes generated by the software programs running on the first and second information processing terminals, respectively.
A method for transferring multimedia data between processes generated by software programs each running on information processing terminals, wherein the information processing terminals are capable to communicate with each other through at least one call connection controller that accommodates a plurality of extension terminals, the method comprising:
- a) storing association information in a database when an association operation has been performed between an extension terminal and an information processing terminal;
- b) during communication between a first extension terminal and a second extension terminal, searching the database to determine the presence or absence of first and second information processing terminals that have completed the association operations with the first and second extension terminals and statuses of software programs on the first and second information processing terminals;
- and
- c) when the first and second information processing terminals have been found and both of the software programs are ready and currently unused, starting transfer of multimedia data between processes generated by the software programs running on the first and second information processing terminals, respectively.
A call connection controller accommodating a plurality of extension terminals in a system for transferring multimedia data between processes generated by software programs each running on information processing terminals, comprising:
- a database for storing association information when an association operation has been performed between an extension terminal and an information processing terminal, which are both connected to the call connection controller;
- a determining section for determining the presence or absence of an information processing terminal that has completed the association operation and a status of a software program on the information processing terminal;
- and
- a communications controller controlling such that, during communication between a first extension terminal and a second extension terminal, when first and second information processing terminals that have completed the association operations with the first and second extension terminals have been found and both of software programs on the first and second information processing terminals are ready and currently unused, multimedia data starts transferring between processes generated by the software programs running on the first and second information processing terminals, respectively.
A method for associating an extension terminal with a process generated by a software program running on an information processing terminal to transfer multimedia data between processes generated by software programs each running on information processing terminals, the method comprising:
- when one of a call originating operation and a call receiving operation is performed at an extension terminal, storing an other-end terminal number of an other-end extension terminal in a database;
- when starting up a first software program on a first information processing terminal by designating a terminal number of the extension terminal during communication with the other-end extension terminal, registering address information of the first information processing terminal and a status of the first software program for the terminal number in the database;
- querying about the presence or absence of a second information processing terminal associated with the other-end extension terminal and a status of a second software program on the second information processing terminal;
- and
- when receiving a response that the second information processing terminal has been found and the second software program is ready and currently unused, starting transfer of multimedia data between processes generated by the first and second software programs running on the first and second information processing terminals.
A computer-readable program for instructing a computer to transfer multimedia data between processes generated by software programs each running on information processing terminals, wherein the information processing terminals are capable to communicate with each other through at least one call connection controller that accommodates a plurality of extension terminals, the computer-readable program comprising the steps of:
- storing association information in a database when an association operation has been performed between an extension terminal and an information processing terminal;
- during communication between a first extension terminal and a second extension terminal, searching the database to determine the presence or absence of first and second information processing terminals that have completed the association operations with the first and second extension terminals and statuses of software programs on the first and second information processing terminals;
- and
- when the first and second information processing terminals have been found and both of the software programs are ready and currently unused, starting transfer of multimedia data between processes generated by the software programs running on the first and second information processing terminals, respectively.
