These operators maintained full control over the communication infrastructure and could implement standardized <a href=\"https:\/\/ic-services.io\/ko\/%ec%a0%9c%ed%92%88\/%ec%86%8c%ed%94%84%ed%8a%b8%ec%9b%a8%ec%96%b4-%ec%86%94%eb%a3%a8%ec%85%98\/%eb%a6%ac-%eb%af%b8%eb%94%94%ec%97%90%ec%9d%b4%ec%85%98-%ed%94%8c%eb%9e%ab%ed%8f%bc\/\">\uc778\uacc4 \uc778\ud130\ud398\uc774\uc2a4<\/a> to deliver intercepted content and metadata to law enforcement agencies. However, the rise of OTT messaging and voice services has fundamentally disrupted this model. Platforms such as WhatsApp, Telegram, Microsoft Teams, and Signal now handle billions of messages and calls daily across Europe, yet many of these services have historically operated outside the scope of telecom regulation. This means that law enforcement agencies, even when equipped with valid judicial warrants, often cannot access communications that have migrated to these platforms.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">EU \uc9c0\uce68 2018\/1972 EECC: OTT \uc11c\ube44\uc2a4 \uaddc\uc81c \uc801\uc6a9<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">\uadf8\ub9ac\uace0 <strong>\uc720\ub7fd \uc804\uc790 \ud1b5\uc2e0 \uaddc\uc815(<a href=\"https:\/\/eur-lex.europa.eu\/eli\/dir\/2018\/1972\/oj\/eng\" target=\"_blank\" rel=\"noreferrer noopener\">EU \uc9c0\uce68 2018\/1972<\/a>)<\/strong> \ub294 OTT\uc758 \ud569\ubc95\uc801\uc778 \uac10\uccad\uc5d0 \uc9c1\uc811\uc801\uc778 \uc601\ud5a5\uc744 \ubbf8\uce58\ub294 \ud68d\uae30\uc801\uc778 \uaddc\uc81c \ubcc0\ud654\ub97c \uc758\ubbf8\ud569\ub2c8\ub2e4.
