Abstract
The present invention relates to a device for interworking a wireless local area network (WLAN) and a portable Internet. The device establishes a first wireless data path following a first wireless communication protocol with a first network, and establishes a plurality of the second wireless data paths through the first wireless data paths. Here, the plurality of the second wireless data paths follow a second wireless communication protocol and respectively correspond to a plurality of terminal devices. Subsequently, the device establishes a plurality of first network links respectively corresponding to the plurality of terminal devices with the first network, and stores mapping information for the first network link corresponding to a relationship between the plurality of terminal devices and the plurality of first network links.
