<p>The present invention relates to a method for adapting security parameters of services provided for a user terminal in a communication network, the method comprising the steps of: initiating (S10), from the user terminal, an adaptation procedure towards the network, informing (S11) in response thereto, by said network, said user terminal of security parameters available for the services provided for said user terminal, selecting (S12), at said user terminal, at least one security parameter per service, and storing (S14) said selected security parameters per service per user in the network. Also, the present invention concerns a method for communicating data via a communication network to/from a user terminal having subscribed to said network, said method comprising the steps of: requesting (S20) a call to be established for said user terminal, retrieving (S21) security parameters from a subscriber database entity (HSS) of said network for said requested call, informing (S22) a security parameter processing entity (BS) of said network about the retrieved security parameters for said user terminal, and activating (S23) security processings for data communicated to/from said user terminal as defined by said security parameters per service for said user terminal at said security parameter processing unit.</p> |
