In one example of the present invention, a security performance negotiation method for supporting the hand-over of mobile handsets comprises the steps of: carrying out, in advance, a security performance negotiation procedure with a first base station (T-ABS), prior to registration on the first base station; generating a traffic encoding key (TEK) by using security related information acquired by means of the security performance negotiation procedure; and carrying out a general performance exchange procedure encoded by means of the TEK and a zone switch with the first base station."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Security performance negotiation method and a TEK management method","description":"The present invention relates to methods for sending and receiving security related information during handover on a wireless access system and methods for managing a traffic encoding key (TEK).
