There are provided measures for enabling/realizing service continuity in a centralized service network system. Such measures exemplarily comprise detecting a deregistration request for deregistering a terminal with respect to a first switching entity from a registration in which the first switching entity is registered for the terminal as a contact point for centralized services, starting a waiting timer for waiting for a registration request for registering the terminal with respect to a second switching entity upon detection of said deregistration request, and re-registering the terminal in the registration such that the second switching entity is registered for the terminal as a contact point for centralized services upon detection of the registration request for registering the terminal with respect to the second switching entity before expiry of the waiting timer.

Service continuity in centralized service network system

Certain embodiments propose to conceal interception from network operators by receiving a setup message to set up a monitoring connection towards another entity (e.g. an ISUP IAM), analyze the received setup message, and responsive thereto, establish the monitoring connection towards the another entity. The control unit is further configured to confirm that a preconfigured identifier representative for a lawful interception is included within the setup message (e.g. inside the field Called Party Subaddress, under Operator ID&#x2014;octets 4, 5 and 6), and responsive thereto, suppress at least partially a generation of data records for the monitoring connection.
