Abstract:
PURPOSE: A transmission mode switching method for a multicast broadcasting service and a device thereof are provided to efficiently switch a multicast transmission mode and a unicast transmission mode in a mobile communication system based on Mobile WiMAX. CONSTITUTION: An MBS proxy(23) increases a count value indicating the number of mobile terminals receiving a current service. The MBS proxy determines a service flow type which is a transmission mode based on the count value(S170). When the service flow type is changed, a service flow is generated according to the changed type(S220). The service flow is released according to a previous type. If the service flow type is not changed, a service flow for a newly joined mobile terminal is generated.

Abstract:
A method for generating authorization key and a method for negotiating authorization are provided to omit an authentication process in a second network entry by using a master key generated when performing a first network entry. A first network entry is progressed to a base station via a first MAC(Media Access Control) layer. A secondary network entry is progressed to the base station via a second MAC layer and a secondary network entry is for frequency overlay. In a first network entry procedure, a key for proof key creation is obtained through an authentication process according to the certification system negotiated with the base station(100). In the first network entry procedure, a first authentication key is generated with the key for the proof key creation(120). In a secondary network entry procedure, a second authentication key is generated with the key for the proof key creation(200).
Abstract:
An authentication method for offering non-authentication in a portable Internet system is provided to offer a portable Internet service to a user by offering a non-authentication function if authentication is not required between an AT(Access Terminal) and an AP(Access Point) in the portable Internet system. The AP performs an initial wireless access procedure with the AT(S401). The AP receives the first authentication request message including an authentication policy supporting field value from the AT(S402). In case that wireless Internet service support is wanted without authenticating the AT, the AP transmits the first authentication response message setting the authentication policy supporting field value as a specific value to the AT(S404). If the first registration request message for promptly registering the AT without an authentication procedure is received from the AT, the AP sets the authentication policy supporting field value with the specific value for the non-authentication of the AT and transmits the second registration message setting a MAC(Media Access Control) address of the AT to a packet access router(S406).
Abstract:
A method for negotiating a security-related parameter of a subscriber station in a wireless portable internet system is provided to manage a corresponding parameter by including various security-related parameters in one SNP(Security Negotiation Parameters). A method for negotiating a security-related parameter of a subscriber station in a wireless portable internet system includes the steps of: providing a receiver station with PKM(Privacy Key Management) version support information through a security negotiation parameter; providing the receiver station with authorization policy support information through the security negotiation parameter; providing the receiver station with message authentication code mode information through the security negotiation parameter; and providing the receiver station with PN(Packet Number) window size information through the security negotiation parameter.
