For most subscribers, this means faster data and better coverage on 4G and 5G. For Mobile Virtual Network Operators (MVNOs) that run their own voice core, or that move to their own IMS as 3G (and later 2G) networks close, lawful interception has to move to the IMS as well. Light MVNOs that use their host&#8217;s VoLTE service usually remain covered by the host&#8217;s LI.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Under 3G, most light MVNOs relied on their host MNO&#8217;s circuit-switched core, so the host carried out the interception; depending on national law, the MVNO still had its own duties, such as making sure the host could implement orders. Full MVNOs that ran their own switching already operated their own LI.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"margin-bottom:var(--wp--preset--spacing--70)\">For MVNOs that take voice into their own hands, that model changes when circuit-switched voice disappears.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Dal circuito commutato all'IMS: il cambiamento tecnico<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"margin-bottom:var(--wp--preset--spacing--70)\">Con la dismissione del 3G, i servizi vocali migrano verso il VoLTE (Voice over LTE) e il VoNR (Voice over New Radio for 5G). Entrambe le tecnologie forniscono la voce come pacchetti IP sulla rete dati, utilizzando l'architettura IP Multimedia Subsystem (IMS).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Some host MNOs do not offer VoLTE to their MVNOs, and many full MVNOs choose to run their own IMS for control over features and billing. Running its own IMS gives an MVNO more control over service features, billing and customer experience. But it also means the MVNO now controls voice call signalling and, through its IMS media functions, the voice media, and with that it takes on lawful interception duties of its own.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"margin-bottom:var(--wp--preset--spacing--70)\">When the MVNO operates the IMS core that processes voice calls, it becomes an obliged operator for that voice service. The host MNO usually keeps obligations for the radio and packet core it operates, so the two parties must agree who delivers what to avoid gaps and duplicate content.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Cosa devono implementare gli MVNO<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Gli operatori MVNO che stanno passando a una propria infrastruttura IMS hanno bisogno di una soluzione MVNO completa <a href=\"https:\/\/ic-services.io\/it\/soluzioni\/intercettazione-lecita\/\">soluzione per l\u2019intercettazione legale<\/a> che comprende:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><a href=\"https:\/\/ic-services.io\/it\/prodotti\/soluzioni-software\/sistema-di-gestione-delle-intercettazioni-legali\/\">Gestione dei mandati<\/a><\/strong><br>A system to receive, validate and track lawful interception requests from law enforcement agencies. This includes managing target identities (for IMS voice, for example the IMPU\/TEL URI, IMPI, MSISDN or IMEI), warrant timelines and authorized agency access.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Punti di intercettazione IMS<\/strong><br>Integration with the IMS core to collect Intercept Related Information (IRI) and Content of Communication (CC) for VoLTE and VoNR calls. This requires interception of signalling (IRI) at the P-CSCF\/S-CSCF and of media (CC) at the media-plane functions such as the IMS-AGW, TrGW or MRF (3GPP TS 33.127).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Mediazione e formattazione<\/strong><br>A <a href=\"https:\/\/ic-services.io\/it\/prodotti\/soluzioni-software\/piattaforma-di-mediazione\/\">piattaforma di mediazione<\/a> that receives the X2\/X3 output of the IMS points of interception and delivers it in the handover format required nationally, for example <a href=\"https:\/\/www.etsi.org\/deliver\/etsi_ts\/102200_102299\/10223205\/\" target=\"_blank\" rel=\"noopener\">ETSI TS 102 232-5<\/a> for IP multimedia, used with the <a href=\"https:\/\/www.etsi.org\/deliver\/etsi_ts\/102200_102299\/10223201\/03.34.01_60\/ts_10223201v033401p.pdf\" target=\"_blank\" rel=\"noopener\">TS 102 232-1<\/a> PS-PDU (as in Germany), or 3GPP TS 33.108\/33.128.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Passaggio di consegne sicuro<\/strong><br>Canali di trasmissione crittografati (HI2 per IRI, HI3 per CC) verso <a href=\"https:\/\/ic-services.io\/it\/prodotti\/soluzioni-software\/struttura-di-monitoraggio-delle-forze-dellordine\/\">strutture di monitoraggio delle forze dell'ordine<\/a>, con autenticazione reciproca, conferma di consegna e registrazione dei log di controllo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Rapporti di conformit\u00e0<\/strong><br>Funzionalit\u00e0 di documentazione e reporting per dimostrare la conformit\u00e0 durante gli audit normativi e rispondere alle richieste di informazioni sullo stato delle intercettazioni.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Costruire questa infrastruttura internamente richiede competenze specialistiche negli standard 3GPP, nelle specifiche ETSI LI, nell'architettura IMS e nei requisiti di interfaccia con le forze dell'ordine, competenze che la maggior parte degli MVNO non ha in organico.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Tre strade da percorrere per gli MVNO<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Gli MVNO che devono affrontare questa sfida hanno tre opzioni principali:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Opzione 1: costruire in casa<\/strong><br>Assumere specialisti LI, acquistare software di mediazione, integrarsi con elementi IMS e stabilire connessioni LEA. Ci\u00f2 offre il massimo controllo, ma richiede un investimento significativo di capitale, costi operativi continui e la capacit\u00e0 di stare al passo con l'evoluzione degli standard.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Opzione 2: <a href=\"https:\/\/ic-services.io\/it\/servizi\/operazioni-di-li-gestite\/\">LI gestito<\/a> Servizio<\/strong><br>Outsource the entire LI operation to a specialist provider like ICS. The provider operates the mediation platform, manages warrant lifecycles, handles LEA handover and runs day-to-day compliance on your behalf. The legal obligation stays with you. The MVNO maintains oversight but avoids building specialized infrastructure and hiring dedicated staff.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Opzione 3: Piattaforma software con supporto<\/strong><br>Concessione in licenza del software di gestione e mediazione LI ed esecuzione sulla propria infrastruttura, con supporto all'implementazione, formazione e consulenza continua da parte di uno specialista LI. Questa via di mezzo vi permette di avere il controllo e di sfruttare le competenze esterne per la configurazione e la manutenzione.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Most MVNOs find that managed services or supported software platforms offer the best balance of compliance assurance, cost control and operational simplicity. The business case for building in-house only makes sense at significant scale \u2013 typically two to three million subscribers or more in one market.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Non aspettate l'ultimo minuto<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Shutdown timelines vary by country, but the trend is clear: circuit-switched voice is ending, IMS is the future, and MVNOs that operate their own IMS need their own lawful interception solutions. Regulators expect compliance from day one of IMS operation \u2013 there&#8217;s no grace period for MVNOs to &#8220;figure it out later.&#8221;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">ICS aiuta gli MVNO a gestire questa transizione <a href=\"https:\/\/ic-services.io\/it\/soluzioni\/\">con soluzioni flessibili<\/a> che si adattano alle vostre tempistiche, al vostro budget e al vostro ambiente tecnico.
