Abstract
The invention allows changing a Radio Access Network security algorithm during handover in a manner that is efficient and secure. A security message is received at a mobile station previously using a first security algorithm in communication with a first access point, which message instructs to use a second security algorithm required by a second access point. In response, the mobile station is changed to use the second security algorithm.
