Abstract:
1. A method for establishing security bindings between a sending network entity and a receiving network entity, the method comprising: sending, by the sending network entity, a first security binding request to a first authentication entity wherein the first security binding request includes requested security binding parameters; determining, by the first authentication entity, proposed security bindings parameters for the sending network entity; sending, by the first authentication entity, a second security binding request to a second authentication entity, wherein the security binding request includes identification information for the receiving network entity and proposed security binding parameters; determining, by the second authentication entity, whether the proposed security binding parameters are applicable to the receiving network entity; sending, by the second authentication entity, to the first authentication entity an indication of which proposed security binding parameters are acceptable; sending, by the first authentication entity, a response to the sending network entity indicating the accepted security binding parameters; and determining, by the sending network entity, whether the accepted security binding parameters are sufficient, if yes, then sending an security binding acceptance indication to the receiving network entity via the first authentication entity and the second authentication entity.
