Abstract:
A method for providing Law Enforcement Agencies in a telecommunications network with interception and/or retention data related to a target mobile node (1) in a Proxy Mobile Internet Protocol domain (2) connected to the telecommunications network through a Mobile Access Gateway (3), comprises the steps of configuring at least one of said Mobile Access Gateway (3) and a Local Mobility Anchor (4) to operate as Intercepting Control Elements (11) or Data Retention sources.
Abstract:
A method for reducing consumption of resources for lawful interception or retention data related to traffic concerning a 2G/3G target mobile connected to a telecommunications network interworking with Evolved Packet System, comprises the steps of: at a first node, detecting at least a parameter value in data for which lawful interception or data retention has been activated; based on the at least parameter value, evaluating whether the traffic is intercepted or retained at a second node crossed by the traffic in the same network; filtering out lawful interception requests or intercepted data if the second node is located downstream of the first node.
Abstract:
The present invention relates to methods and arrangements in a mobile telecommunication system to generate interception related information IRI, including geographical location of a monitored mobile subscriber/equipment. The system is configured to provide to an Intercept configuration unit ICU, information collected from an Intercept Access Point IAP; MSC. The system is also configured to proceed with a Network Induced Location Request NI-LR procedure, which method comprises the following steps: - Receiving to the Intercept Access Point (IAP; MSC) from the Intercept configuration unit (ICU), a request to monitor the mobile subscriber/equipment (MSA), - Detecting in the Intercept Access Point (IAP; MSC) of a specified Interception Related Information activity IRI involving the monitored subscriber/equipment(MSA), - The Intercept Access Point IAP; MSC initiates start of the Network Induced Location Request NI-LR procedure.
Abstract:
The present invention relates to methods and arrangements in a telecommunication system to generate Interception Related Information IRI related to positioning activities involving a mobile subscriber/equipment MSA. The system provides information to an Intercept configuration unit ICU, collected from an Intercept Access Point IAP; MSC, GMLC that is associated to the monitored subscriber/equipment. The method comprises the following steps: receiving to the Intercept Access Point IAP; MSC, GMLC from the Intercept configuration unit ICU, a request to monitor the mobile subscriber/equipment MSA. Registration in the Intercept Access Point IAP; MSC, GMLC, of a positioning activity involving the monitored subscriber/equipment. Delivering information related to the positioning activity, from the Intercept Access Point IAP; MSC, GMLC to the Law Enforcement Agency LEA.
