1. A terminal apparatus of communicating with at least one other terminal apparatus via a communication medium, comprising:
- an operation mode setting section operable to set the terminal apparatus to operate as a control terminal controlling an opportunity of access of the other terminal apparatus to the communication medium or as a controlled terminal whose opportunity of access to the communication medium is controlled by another terminal apparatus operating as a control terminal;
an interference recognizing section operable to recognize interference from at least one logical network other than a logical network to be controlled, when the operation mode setting section sets the terminal apparatus to operate as the control terminal;
a unification determining section operable to determine whether or not the logical network to be controlled is unified with the other logical network, when the interference recognizing section recognizes the interference from the other logical network; and
a new control terminal determining section operable to determine whether a control terminal of a logical network newly created by unification is the terminal apparatus or a control terminal of the other logical network, when the unification determining section determines that the logical network to be controlled is unified with the other logical network, wherein the operation mode setting section sets the terminal apparatus to operate as the control terminal of the newly created logical network, when the new control terminal determining section determines that the control terminal of the newly created logical network is the terminal apparatus, and the operation mode setting section sets the terminal apparatus to operate as a controlled terminal of the newly created logical network, when the new control terminal determining section determines that the control terminal of the newly created logical network is the control terminal of the other logical network.

Abstract
When operating as a control terminal and recognizing interference from another logical network, a terminal apparatus determines whether or not a logical network to be controlled is unified with the other logical network. When unification is determined, the terminal apparatus determines whether a control terminal of a logical network newly created by unification is the terminal apparatus or a control terminal of the other logical network.

11. A processing method of a communication terminal communicating with at least one other terminal apparatus via a communication medium, comprising the steps of:
-
setting the communication terminal to operate as a control terminal controlling an opportunity of access of the other terminal apparatus to the communication medium or as a controlled terminal whose opportunity of access to the communication medium is controlled by another terminal apparatus operating as a control terminal;
recognizing interference from at least one logical network other than a logical network to be controlled, when the communication terminal is set to operate as the control terminal;
determining whether or not the logical network to be controlled is unified with the other logical network, when the interference from the other logical network is recognized;
determining whether a control terminal of a logical network newly created by unification is the communication terminal or a control terminal of the other logical network, when it is determined that the logical network to be controlled is unified with the other logical network;
setting the communication terminal to operate as the control terminal of the newly created logical network, when it is determined that the control terminal of the newly created logical network is the communication terminal; and
setting the communication terminal to operate as a controlled terminal of the newly created logical network, when it is determined that the control terminal of the newly created logical network is the control terminal of the other logical network.
