Patent number: 11876838Abstract: Methods and devices employed in providing lawful interception (LI) by products related to a service session of an LI target as a unique chain. The packets sent to a legal enforcement agency are chained and have shorter headers. The number of packets is reduced by including both intercept-related information (IRI) and content of communications (CC) in the same packet if time-wise appropriate.Type: GrantFiled: October 4, 2018Date of Patent: January 16, 2024Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Amedeo Imbimbo, Mario Ascione, Francesca Marfia

Patent number: 11870820Abstract: Automatic preparation of data related to session initiation protocol (SIP) based traffic flows in a lawful interception (LI) scenario is disclosed. The dataset that is obtained may, e.g., be used for machine learning-based (ML) and artificial intelligence (AI) tools that can identify lawfully intercepted SIP-based traffic cases. Such preparation of data reduces the 5 risk of misunderstandings between a communications service provider (CSP) and a law enforcement agency (LEA), which reduces the time dedicated by both parties in understanding the correctness of LI data provided by the CSP to the LEA.Type: GrantFiled: June 10, 2019Date of Patent: January 9, 2024Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Francesca Marfia, Gianluca Avagliano

Patent number: 11777998Abstract: A mechanism is provided that enables hiding identities of a target subscriber that is to be subject of lawful interception, LI, when the intercept access point, IAP, is outside the network operator part of the LI domain. Monitoring of data traffic such as over-the-top, OTT, services is enabled while at the same time hiding LI target identities to a network element, NE, containing the IAP. A secure memory area in the NE is dedicated to the LI functionality necessary to intercept and report interception data to the operator part of the LI domain. The interface between the NE and the operator part of the LI domain is the use of a secure injection channel via which the necessary LI software and target information are conveyed between the NE and the operator part of the LI domain.Type: GrantFiled: October 4, 2018Date of Patent: October 3, 2023Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Claudio Carotenuto, Elio Barese, Paolo D'Amora, Francesca Marfia, Vincenzo Paparo

Publication number: 20230027052Abstract: Methods and devices provide service-specific information besides LI data extracted from communications of LI targets, which receive services via the network and interact with a core function of the network. LI data includes at least one of IRI and CC. This approach is particularly useful if LI at application/service level is unavailable.Type: ApplicationFiled: December 18, 2019Publication date: January 26, 2023Inventors: Francesca Marfia, Chiara Santella, Antonio Luisi, Abramo Marino, Luciano Orabona, Vincenzo Cuniato

Patent number: 11363136Abstract: A declarative mechanism is provided in the context of lawful interception (LI). A manifesto with information that specifies LI of a communication service or application is created and declared by a service or application provider who, is subject to LI. The declaration takes place in that the manifesto is provided from a first LI function to other LI functions in a communication system. LI data (e.g., call data record, intercept related information and call content) is subsequently generated during LI according to the manifesto by a point of interception within the service or application. The point of interception delivers the LI data to a mediation and delivery function that then forwards it to a law enforcement agency. The law enforcement agency knows how to read and manage the LI data from the manifesto.Type: GrantFiled: September 5, 2018Date of Patent: June 14, 2022Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Amedeo Imbimbo, Francesca Marfia, Mario Ascione

Patent number: 11303680Abstract: 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.Type: GrantFiled: July 15, 2015Date of Patent: April 12, 2022Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Francesca Marfia, Lorenzo Fiorillo
