Data communication system and data communication terminal as well as data communication method used therefor and program used therefor
First Claim
1. A data communication system including:
- a plurality of network; and
a plurality of terminal being accessible to said plurality of network, wherein each of said plurality of network is assigned with each network property value, and wherein each of said plurality of terminal further includes;
at least an access policy for making a decision on permissibility for access to other terminal of said plurality of terminal than said each terminal, with reference to at least one of a first network property value assigned to a first network connected with said each terminal and a second network property value assigned to a second network connected with said other terminal, so that only when said access is permitted based on said access policy, then said terminal makes an access to said other terminal.

Abstract
A data communication system includes a plurality of network and a plurality of terminal being accessible to the plurality of network. Each of the plurality of network is assigned with each network property value. Each of the plurality of terminal further includes: at least an access policy for making a decision on permissibility for access to other terminal of the plurality of terminal than the each terminal, with reference to at least one of a first network property value assigned to a first network connected with the each terminal and a second network property value assigned to a second network connected with the other terminal, so that only when the access is permitted based on the access policy, then the terminal makes an access to the other terminal.

41. A terminal accessible though a plurality of network assigned with each network property value to other terminal for data communication, said terminal including:
-
an access policy storing unit for storing at least an access policy; and
an access permission decision function block for making a decision on permissibility for access to said other terminal, with reference to at least one of a first network property value assigned to a first network connected with said terminal and a second network property value assigned to a second network connected with said other terminal, so that only when said access is permitted based on said access policy, then said terminal makes an access to said other terminal. - View Dependent Claims (42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74)

75. A method for data communication between a plurality of terminal being accessible through a plurality of network, said method including:
-
assigning each network property value to each of said plurality of network;
setting at least an access policy;
making a decision on permissibility for access from a terminal to other terminal of said plurality of terminal, with reference to at least one of a first network property value assigned to a first network connected with said each terminal and a second network property value assigned to a second network connected with said other terminal; and
making an access to said other terminal only when said access is permitted based on said access policy. - View Dependent Claims (76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112)
