Wireless communication system for interconnecting ad-hoc network and infrastructure network, and wireless terminal and communication method therefor
First Claim
1. A communication method of a wireless terminal in a wireless communication system comprising an Infrastructure (IS) network, the method comprising:
- broadcasting a discovery signal comprising terminal information of the wireless terminal to a radio network over a common channel;
receiving a response signal comprising information for network access from one of a base station and another wireless terminal, which received the discovery signal;
selecting an operation mode for access to a network through one of the base station and the other wireless terminal, based on the response signal;
communicating with the base station and accessing the IS network when the selected operation mode corresponds to a first mode; and
accessing a network, to which the other wireless terminal belongs, through a licensed frequency band of the IS network when the selected operation mode corresponds to a second mode,wherein the second mode comprises a dual mode for accessing an ad-hoc network that uses a licensed frequency band of the IS network when the network to which the other wireless terminal belongs is the ad-hoc network.

Abstract
A wireless communication system for interconnecting an ad-hoc network and an IS network, and a wireless terminal and communication method therefor are disclosed. The communication method includes transmitting a discovery signal including terminal information of the wireless terminal to a radio network, receiving a response signal including information for network access from a base station or another wireless terminal, which has received the discovery signal, selecting an operation mode for access to a network through the base station or the other wireless terminal, based on the response signal, communicating with the base station and accessing the IS network when the selected operation mode corresponds to a first mode and accessing a network, to which the other wireless terminal belongs, through a licensed frequency band of the IS network when the selected operation mode corresponds to a second mode. Accordingly, it is possible to support communication through an existing infrastructure and support communication of an ad-hoc network scheme, through use of a licensed frequency band assigned to the provider of an existing IS network.

8. A wireless terminal in a wireless communication system comprising an Infrastructure (IS) network, the wireless terminal comprising:
-
a transceiver for transmitting and receiving signals over a radio network; and a controller for controlling operations for broadcasting a discovery signal comprising terminal information of the wireless terminal to the radio network over a common channel and for receiving a response signal comprising information for network access from one of a base station and another wireless terminal, which has received the discovery signal, for analyzing the response signal and selecting an operation mode suitable for current network circumstance, and for communicating with the base station, to access the IS network when the selected operation mode corresponds to a first mode and to access a network, to which the other wireless terminal belongs, through a licensed frequency band of the IS network when the selected operation mode corresponds to a second mode, wherein the second mode comprises a dual mode for accessing an ad-hoc network that uses the licensed frequency band of the IS network when the network to which the other wireless terminal belongs is the ad-hoc network. - View Dependent Claims (9, 10, 11, 12)
