Open wireless access network apparatus and connection method using the same

An open wireless access network apparatus comprising:

• a subscriber Internet protocol (IP) management unit configured to allocate to a mobile device an IP allocated from a first wireless access point (AP) from among a plurality of wireless APs;
• a subscriber connection control management unit configured to provide a second wireless AP with the IP allocated from the first wireless AP when the mobile device changes from one area in which the mobile device has a signal delivered from the first wireless AP to another area in which the mobile device has a signal delivered from the second wireless AP, and to include grade of service, service time, traffic and information about a provider server selected from a plurality of provider servers with respect to each user of the mobile device;
• and
• a wireless connection module configured to be connected to a provider server that provides an Internet service through the IP allocated by the subscriber connection control management unit
• wherein at least one of the IP resource management unit, the subscriber movement management unit, the wireless AP connection control unit is implemented by a processor.

A connection method using a open network apparatus, the connection method comprising:

• setting common access region using some IP resources, and allocating an IP corresponding to the common access region to open wireless access points (APs), each of which provides wireless Internet to a mobile device and a plurality of provider servers, each of provider server providing an Internet service;
• in response to an Internet service request from the mobile device, allocating an IP to the mobile device based on subscriber information, and allowing the mobile device to be provided with an Internet service from a particular provider server among a plurality of the provider servers;
• in response to the mobile device moving from an area in which the mobile device has a signal delivered from a first wireless AP among a plurality of the open wireless APs to an area in which the mobile device has a signal delivered from a second wireless AP, allowing the second wireless AP to be provided with an IP allocated to the first wireless AP by enabling the second wireless AP to communicate with the first wireless AP to receive the IP allocated to the mobile device;
• mapping an IP of the particular provider server corresponding to the IP that is provided to the second wireless AP and thereby allowing the mobile device to identify the IP of the particular provider server that is connected through the first wireless AP;
• and
• terminating connection between the first wireless AP and the particular provider server and connecting the second wireless AP and the particular provider server.
