Reducing core network traffic caused by migrant users

An apparatus for reducing core network traffic caused by:

• migrant users of a public wireless network, comprising:
• means for a communication interface receiving a plurality of internet protocol (IP) addresses from a dynamic host configuration protocol (DHCP) server, wherein said communication interface comprises a wired interface and a wireless interface;
• means for memory for storing said received plurality of IP addresses;
• means for said wireless interface receiving a DHCP discover request from a wireless client device;
• means for a hardware processor for determining if there are enough IP addresses available to assign one of said plurality of IP addresses to said wireless client device when there are enough IP addresses available to assign, said hardware processor in bi-directional communication with said wired interface and said wireless interface;
• means for said wireless interface transmitting a DHCP acknowledgement including said assigned IP address and a lease duration to said wireless client device, said lease duration providing a time period within which said wireless client device may request access to the core network;
• means for said hardware processor determining if a first lease timeout has occurred without said wireless client device requesting access to the core network;
• means for said hardware processor releasing said assigned IP address if said first lease timeout has occurred;
• means for said wireless interface receiving a first hypertext transfer protocol (HTTP) request or a first hypertext transfer protocol secure (HTTPS) request from said wireless client device;
• means for said communication interface relaying a media access control (MAC) pre-authentication request from said wireless client to an authentication, authorization and accounting (AAA) server;
• means for said communication interface receiving a media access control (MAC) pre-authentication response from said AAA server;
• means for said communication interface providing access to the Internet via the wireless client device;
• means for said hardware processor determining if a denial of service (DoS) attack has occurred;
• means for said communication interface relaying said MAC pre-authentication request from said wireless client to an authentication, authorization and accounting (AAA) server upon determining said DoS attack has not occurred;
• means for said communication interface receiving said MAC pre-authentication response from said AAA server;
• means for said hardware processor determining if said first lease timeout has occurred without said wireless client device requesting access to the core network;
• means for said hardware processor releasing said assigned IP address if said first lease timeout has occurred;
• means for said hardware processor determining if a command is available if said first lease timeout has not occurred;
• and
• means for said wireless interface receiving a third HTTP request or a third HTTPS request from said wireless client device if said first lease timeout has not occurred and said command available.

An apparatus for reducing core network traffic caused by migrant users of a public wireless network, comprising:

• a communication interface for receiving a plurality of internet protocol (IP) addresses from a dynamic host configuration protocol (DHCP) server, said communication interface comprising a wired interface and a wireless interface, said wireless interface receiving a DHCP discover request from a wireless client device;
• a memory for storing said received plurality of IP addresses;
• a hardware processor for determining if there are enough IP addresses available to assign one of said plurality of IP addresses to said wireless client device when there are enough IP addresses available to assign, said hardware processor being in bi-directional communication with said wired interface and said wireless interface, wherein
• said wireless interface transmits a DHCP acknowledgement including said assigned IP address and a lease duration to said wireless client device, said lease duration providing a time period within which said wireless client device may request access to the core network, said hardware processor determines if a first lease timeout has occurred without said wireless client device requesting access to the core network and releases said assigned IP address if said first lease timeout has occurred,
• upon determining said first lease timeout has not occurred, wireless interface receives a first hypertext transfer protocol (HTTP) request or a first hypertext transfer protocol secure (HTTPS) request from said wireless client device;
• said communication interface relays a media access control (MAC) pre-authentication request from said wireless client to an authentication, authorization and accounting (AAA) server, receives a media access control (MAC) pre-authentication response from said AAA server and provides access to the Internet via the wireless client device;
• said hardware processor determines if a denial of service (DoS) attack has occurred and upon determining a DoS attack has not occurred, said communication interface relaying said MAC pre-authentication request from said wireless client to an authentication, authorization and accounting (AAA) server and receives said MAC pre-authentication response from said AAA server, said hardware processor determines if said first lease timeout has occurred without said wireless client device requesting access to the core network, wherein
• said hardware processor releases said assigned IP address if said first lease timeout has occurred;
• and upon determining said first lease timeout has not occurred
• said hardware processor determines if a command is available and said wireless interface receives a third HTTP request or a third HTTPS request from said wireless client device if said command available.
