The present disclosure provide a node and method performed in the node for connecting at least two Lawful Interception (LI) sites () to the same Physical Networks Function (PNF) comprising a Point Of Interception (POI) or Virtual Networks Function (VNF) () comprising a virtualised Point Of Interception (vPOI) () controlled by a Triggering Control Function (TCF) (), for lawful interception of the data communication sessions of targets defined by warrants comprising information identifying the targets, wherein said node () is adapted to configure the POIs/vPOIs/TCFs according to LI sites requests and policy requirements for each LI site, the node comprises a multi LI Site Database, mLSDB, () enabling the POI or vPOI/TCF to serve more than one LI site at the same time.

Method, node and computer program of lawful interception systems and networks

A technique for service change and service fallback in intelligent networks is described. The network comprises a service control functional component () and a service switching functional component (). A method implementation of the technique includes the step of obtaining () from the service switching functional component () service preference information for at least one of two or more services indicating a preferred service for a user equipment (). Further, a service is selected () based on the service preference information and service availability information relating to required resources for at least one of the two or more services. The determined service for service change or service fallback is then indicated () to the service switching functional component.
