Abstract
A method for transmitting a handover security context of a first access point, when an access terminal from a service cell of a first access point is connected to a packet access router, to a service cell of a second access point connected to the packet access router, is provided. The handover security context transmitting method includes confirming whether a handover confirmation message transmitted from the access terminal has a security context therein; when the handover confirmation message has a security context therein, confirming whether the security context has security-related information therein; when the security context has security-related information therein, confirming whether the security context has a traffic-related key or a pairwise master key; and transmitting an information instruction message including the security related information confirmed in the security context, the security-related information, the traffic-related key, and the pairwise master key through the PAR to the second AP.
