03.333G security3GPPLawful InterceptionStage 2TS

Figures A10 and A11 show the interception of a call involving both call waiting and call forwarding on no reply. Figure A10 covers the case where one pair of stublines is used per target, figureĀ A11 covers the case where a pair of stublines is used for each target call. The mobile that activated call forwarding on no reply and receives the waiting call (B) is the target for interception. In figure A10 a new (pair of) stublines needs to be set up when the call is forwarded since the first (pair of) stublines is still used for the initial call.
