Conference system and terminal apparatus

A terminal apparatus that exchanges communication data with terminal apparatuses constituting a conference system in which access restrictions to system resources are performed on the basis of preset access control information such that instructions are given, the terminal apparatus comprising:

• instruction inputting means to which user's instructions are input;
• communication controlling means that controls communication between the terminal apparatus and other apparatuses;
• access privilege granting means that, when predetermined access privileges to available system resources including a conference participation right are set through the instruction inputting means for a target to which access rights are to be granted, generates permission information according to the set access privileges, and sends the permission information to the target through the communication controlling means;
• permission information storage means that stores the permission information;
• and
• access privilege setting means that, upon obtaining the permission information from the other terminal apparatuses through the communication controlling means, causes the obtained permission information to be stored in the permission information storage means as well as sends the permission information to a conference management apparatus that manages access restrictions to the system resources, if necessary, so as to enable the access privilege.

A conference system in which communication data including audio information generated at a conference is exchanged between terminal apparatuses as well as access restrictions to system resources are performed on the basis of preset access control information, the conference system comprising:

• a plurality of terminal apparatuses;
• and
• a conference management apparatus, wherein
• the terminal apparatus has
• an access privilege granting unit that, when predetermined access privileges to available system resources including a conference participation right are set for a target to which access rights are to be granted, generates permission information according to the set access privileges, and sends the permission information to the target,
• a permission information storage device that stores the permission information, and
• an access privilege setting unit that obtains the permission information so as to cause the permission information to be stored in the permission information storage device as well as sends the permission information to the conference management apparatus that manages access restriction to the system resources so as to enable the access privilege, and wherein
• the conference management apparatus has
• an access control information updating unit that, upon receiving the permission information from the terminal apparatus, updates the access control information according to the permission information, and
• an access restriction management unit that performs the access restrictions to the system resources on the basis of the access control information updated by the access control information updating unit.

A terminal apparatus that exchanges communication data with terminal apparatuses constituting a conference system in which access restrictions to system resources are performed on the basis of preset access control information such that instructions are given, the terminal apparatus comprising:

• an instruction inputting unit to which user's instructions are input;
• a communication controlling unit that controls communication between the terminal apparatus and other apparatuses;
• an access privilege granting unit that, when predetermined access privileges to available system resources including a conference participation right are set through the instruction inputting unit for a target to which access rights are to be granted, generates permission information according to the set access privileges, and sends the permission information to the target through the communication controlling unit;
• a permission information storage device that stores the permission information;
• and
• an access privilege setting unit that, upon obtaining the permission information from the other terminal apparatuses through the communication controlling unit, causes the obtained permission information to be stored in the permission information storage device as well as sends the permission information to a conference management apparatus that manages access restrictions to the system resources, if necessary, so as to enable the access privilege.
