<p>A method of authenticating a paging request within an IP environment, said environment comprising a paging area having a plurality of access router (PAR, AR) and at least one mobile node (MN), said method comprising the steps of: sharing a session security key (K) between said mobile node (MN) and an access router (PAR) to which said mobile node (MN) has been previously attached to; receiving (S1) a packet incoming for said mobile node (MN) by said previous access router (PAR), wherein said mobile node (MN) is in a dormant mode; submitting (S2) a paging request to all other access routers (AR) of said paging area by said previous access router (PAR) about the packet which came in, thereby also distributing said session security key (K); generating (S3) authentication parameters according to a predetermined process by an access router (AR) to which said mobile node (MN) is currently attached to; submitting (S4) said paging request from said access router (AR) to said mobile node (MN) including said authentication parameters; verifying (S5) the validity of said request by said mobile node (MN), wherein said authentication parameters are processed according to said predetermined process; and submitting (S6) a paging response from said mobile node (MN) to said access router (AR), wherein said response authenticates said paging request.</p> |
