Abstract
Public wireless communications will increasingly extend into wireless LAN (WLAN) environments in order to meet the ubiquitous access, high data rate, and local services demands of future Internet appliances. By relying on IP-level services mechanisms, the Public Access Mobility LAN (PAMLAN) can simultaneously support different air interfaces, franchises for multiple services providers, and a multi-segment LAN environment including handoffs. The PAMLAN supports virtual operator LANs representing different network services providers, authorization and accounting mechanism, support of multiple air interfaces, and local IP mobility. A router associated with each base station realizes this highly distributed IP networking environment, and a QoS-enabled switched Ethernet core supports virtual networks and QoS services.

18. A method of authenticating a mobile subscriber accessing a wireless network, wherein the mobile subscriber accesses wireless network through an air access point comprising of an air interface and a computer, and the air access point computer is coupled to an database server storing a public key associated with the mobile subscriber, the method comprising:
-
sending a first message from the mobile terminal to the air access computer having a user identification number, computing a first codeword, and forwarding the first codeword to the database computer;
sending a second codeword from the database computer to the air access point computer;
extracting a first random character string from the second codeword, and sending a second message comprising the user identification number and a first random character string to the mobile terminal;
sending a third message from the mobile terminal to the air access computer having a user identification number, the first random character string, a second random character string, and a third codeword;
computing a fourth codeword based on the third message received from the mobile terminal, and sending the fourth codeword to the database computer;
computing a fifth codeword at the database computer and sending the fifth codeword to the air access computer; and
computing a sixth codeword and sending a fourth message from the air access computer to the mobile terminal comprised of the user identification number and the sixth codeword.

43. A computer software product for authenticating a mobile subscriber accessing a wireless network, wherein the mobile subscriber accesses wireless network through an air access point comprising of an air interface and a computer, and the air access point computer is coupled to an database server storing a public key associated with the mobile subscriber, wherein the computer software product comprises:
software instructions that enable the air access computer and the database computer to perform predetermined operations, and a computer readable medium bearing the software instructions, wherein the predetermined operations comprise;
sending a first message from the mobile terminal to the air access computer having a user identification number, computing a first codeword, and forwarding the first codeword to the database computer;
sending a second codeword from the database computer to the air access point computer;
extracting a first random character string from the second codeword, and sending a second message comprising the user identification number and a first random character string to the mobile terminal;
sending a third message from the mobile terminal to the air access computer having a user identification number, the first random character string, a second random character string, and a third codeword;
computing a fourth codeword based on the third message received from the mobile terminal, and sending the fourth codeword to the database computer;
computing a fifth codeword at the database computer and sending the fifth codeword to the air access computer; and
computing a sixth codeword and sending a fourth message from the air access computer to the mobile terminal comprised of the user identification number and the sixth codeword. - View Dependent Claims (44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65)
