Device and method of controlling and switching terminals provided with specific communication systems among a plurality of standard communication system

摘要

A method for controlling and switching terminals includes a writing step and a logoff step. In the writing step, when there is a connection request from a given terminal, a processor of a switching device writes, into a memory, user identification information, a password, identification information of a communication system, and an IP address and port number so that their information and data are associated with one another. In the logoff step, if the same user identification information, password, and identification information of communication system as the above are already written in the memory, the processor logs off the other terminal that has the IP address and port number that are already so written in the storage unit as to be associated with the user identification information, the password, and the identification information of communication system.

主权项

1. A device for switching terminals provided with specific communication systems among a plurality of certain communication systems the device comprising:
a processor and a memory containing a list of logged in terminals, comprising username and password combinations and a list of supported communication types comprising one or more of: voice communication system, a video communication system, a text communication system, a file-sharing communication system, a whiteboard-sharing system and an application-sharing communication system; wherein, when the switching device receives a connection request from a first terminal, the processor checks the list of the logged terminals to determine if there exists a second terminal that has logged in with a same user identification information as that of the first terminal and with a same password as that of the first terminal; (A) if the second terminal does not exist, the processor writes, into the list of logged in terminals, user identification information of the first terminal, a password corresponding to the identification information, and identification of communication type that the first terminal is equipped with, so that the user identification information, the password, and the identification of the communication types are associated with one another to record the first terminal as in log-in state; and (B) if the second terminal exists, the processor further confirms whether the second terminal has logged in with any of the same communication types as that of the first terminal by inspecting the list of logged in terminals; and (C) the processor logs off the second terminal even when the second terminal is engaged in a different kind of communication system from the already written communication system out of the already written user identification information, password and communication system.
