Abstract
Method and arrangement for intercepting a target mobile station in a GPRS network. A legal interception node is installed into the land-based portion of the radio network. An “intercepted” status is defined for mobile stations that are to be intercepted. In response to an order from a law-enforcement authority to intercept one of said mobile stations the status of such mobile station is changed to “intercepted” and at least some of the packets originating from such a mobile station or terminated thereto are routed and/or copied from at least one of the support nodes via the legal interception node to the law-enforcement authority.
