The present invention relates to methods and arrangements to perform monitoring-continuity in case of number portability in a telecommunication system. The method comprises a step wherein a monitored user (B) requires number portability from an operator of a donor network (DNW) to an operator of a recipient network (RNW). The method further comprises the receiving of a number portability event - temporary address (NPEl) to an agency controlled receiving entity (LEMF, ADRS), which event (NPEl) comprises information related to the user's ported identity and the user's new identity.
