Abstract: The disclosure relates to a method in a Lawful Intercept, LI, management system for removing redundant content of communication, CC flows. Said LI management system is capable of receiving and handling one or more CC flows generated from intercepted target communication sessions. Each CC flow comprises a flow of data packets, each data packet comprising a flow identity of the CC flow. The flow identity comprises an address of a sending intercept access point, IAP, at least one target identifier, TID, and a communication session Correlation Identifier, CI. The method enables the LI management system to forward only one CC flow of CC flows having identical TID and CI, respectively, but different sending intercept access points.

Abstract: The present invention relates to a mediation function node in a Lawful Intercept system and a method (S100) in a Lawful Intercept system for enabling a Law Enforcement Agency, LEA, to determine targets' positions. Said targets are connected to a WiFi network via an Access Point. The method comprises steps of: —receiving (S110) a RADIUS account message for a subscriber having been accepted access to the WiFi network; —retrieving (S120) from the received RADIUS account message RADIUS parameters corresponding to an Access Point Identifier and a Service Set Identifier, SSID, if the subscriber is a target; —sending (S130) together with a target identification the RADIUS parameters corresponding to the Access Point Identifier and the SSID to the LEA.

Abstract: The present invention relates to methods and Validity securing arrangement and embodiments thereof for effectively securing validity of a target database in a node in a Lawful Interception Network. Said target database is intended to be identical to a source target database. The arrangement comprises a processing means being adapted to send a request for a target database checksum to the node comprising the target database, to receive a response comprising the target database checksum from the requested node, to compare the received target database checksum to a source target database checksum determined for the corresponding source target database, and to send an order to start an audit and synchronisation process if the two compared checksums differ.

Abstract: Methods and arrangements are provided for maintaining a wanted Quality of Service transmission level of Lawful Interception (LI) payload data to a Law Enforcement Agency (LEA) via an HI3 interface in a LI system. The data is acquired from an intercepted IP packet flow and belongs to one or more target identities using a specific Internet communications service. The method, which is performed by the arrangement, includes monitoring the state of congestion of IP packets in the HI3 interface in relation to a first threshold level T1 and a second threshold level T2. The first threshold level T1 corresponds to a lower level of congestion than the second threshold level T2. The transmission of LI payload data is controlled based on the monitoring and a priority classification assigned to the LI payload data to be transmitted.
