Method and arrangement for intercepting a target mobile station (MS) in a GP RS network. A legal interception node (LIN) is installed into the land-based portion of the radio network. An "intercepted" status is defined for mobile stations (MS) that are to be intercepted. In response to an order from a law-enforcement authority (LEA) to intercept one of said mobile stations (MS) the status of such a mobile station (MS) is changed to "intercepted" and at least some of the packets originating from such a mobile station (MS) or terminated thereto are routed and/or copied from at least one of the support nodes (SGSN, GGSN) via the legal interception node (LIN) to the law-enforcement authority. |
