For home-routed VoLTE (S8HR), the visited network sees no IMS signalling of its own; it needs the S8HR LI functions defined by 3GPP (TS 33.127) and roaming partners that disable IMS signalling encryption towards it. Some countries, such as Germany, instead deliver all of the inbound roamer&#8217;s data traffic. Location reporting also changes: the visited network must report the inbound roamer&#8217;s location itself, while the home network can only report what it sees, such as the visited network&#8217;s identity. Testing your LI capability with roaming scenarios should be part of your regular compliance testing programme.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">\u51fa\u5883\u6f2b\u6e38\uff1a\u5f53\u60a8\u7684\u7528\u6237\u8eab\u5904\u56fd\u5916\u65f6<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">When your subscriber roams onto a foreign network, your ability to intercept their communications depends on the traffic routing architecture. If the subscriber&#8217;s data is home-routed through your PGW or UPF, you retain access to the user-plane traffic and can technically perform interception at your own infrastructure. Whether you may do so is a legal question. Some countries restrict interception of targets who are abroad: in Germany, for example, communications are not captured while the network knows the device is abroad, unless they involve a domestic line (\u00a7 4 TK\u00dcV). Within the EU, the intercepting state must also notify the Member State where the target is located. If the traffic is locally broken out in the visited network, you lose access to the user-plane traffic and cannot intercept the content of communications. You may still have access to signalling information (IRI) related to the subscriber&#8217;s activities, depending on the roaming architecture.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u5f53\u7531\u4e8e\u672c\u5730\u63a5\u5165\u7684\u539f\u56e0\uff0c\u65e0\u6cd5\u901a\u8fc7\u60a8\u81ea\u8eab\u7684\u7f51\u7edc\u57fa\u7840\u8bbe\u65bd\u622a\u83b7\u7528\u6237\u7684\u901a\u4fe1\u65f6\uff0c\u60a8\u5fc5\u987b\u5c06\u8fd9\u4e00\u9650\u5236\u544a\u77e5\u6267\u6cd5\u90e8\u95e8\u3002\u6267\u6cd5\u90e8\u95e8\u968f\u540e\u53ef\u901a\u8fc7\u5229\u7528\u73b0\u6709\u7684\u8de8\u5883\u5408\u4f5c\u673a\u5236\uff0c\u5411\u7528\u6237\u6f2b\u6e38\u6240\u5728\u56fd\u7684\u6709\u5173\u5f53\u5c40\u7533\u8bf7\u8fdb\u884c\u622a\u83b7\u3002\u8fd9\u4e00\u6d41\u7a0b\u53ef\u80fd\u8f83\u4e3a\u7f13\u6162\uff0c\u4f46\u8fd9\u662f\u7b26\u5408\u6cd5\u5f8b\u89c4\u5b9a\u7684\u6b63\u5f53\u9014\u5f84\u3002.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Operators should detect when a target starts or stops roaming and report this to the agency, and suspend or resume interception as the warrant and national law require.

These intermediary platforms facilitate the exchange of traffic between operators and may have visibility into signalling and, in some architectures, user-plane traffic. The question of whether IPX providers have lawful interception obligations is still evolving, and the answer varies by jurisdiction. In Germany, for example, pure interconnection networks without subscriber lines need no LI precautions, except nodes that switch voice traffic to other countries (\u00a7 3(2) TK\u00dcV). Operators should understand how their roaming traffic flows through IPX providers and what implications this has for interception coverage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u5728\u67d0\u4e9b\u6f2b\u6e38\u67b6\u6784\u4e2d\uff0cIPX\u63d0\u4f9b\u5546\u53ef\u80fd\u4f1a\u63d0\u4f9b\u8bf8\u5982\u6d41\u91cf\u4f18\u5316\u6216\u672c\u5730\u5206\u6d41\u8f85\u52a9\u7b49\u589e\u503c\u670d\u52a1\uff0c\u8fd9\u4e9b\u670d\u52a1\u4f1a\u5f71\u54cd\u76ee\u6807\u6d41\u91cf\u7684\u8def\u7531\u3002\u8fd9\u4e9b\u670d\u52a1\u53ef\u80fd\u4f1a\u6539\u53d8\u622a\u83b7\u70b9\u7684\u4f4d\u7f6e\uff0c\u5e76\u53ef\u80fd\u5bfc\u81f4\u622a\u83b7\u8986\u76d6\u8303\u56f4\u51fa\u73b0\u6f0f\u6d1e\uff0c\u8fd0\u8425\u5546\u5fc5\u987b\u8bc6\u522b\u5e76\u89e3\u51b3\u8fd9\u4e9b\u95ee\u9898\u3002 \u4e86\u89e3\u6f2b\u6e38\u6d41\u91cf\u5b8c\u6574\u7684\u7aef\u5230\u7aef\u8def\u5f84\u2014\u2014\u4ece\u7528\u6237\u8bbe\u5907\u7ecf\u7531\u88ab\u8bbf\u95ee\u7f51\u7edc\u3001IPX\u63d0\u4f9b\u5546\u76f4\u81f3\u672c\u7f51\u2014\u2014\u5bf9\u4e8e\u786e\u4fdd\u80fd\u5728\u9002\u5f53\u7684\u70b9\u4f4d\u8fdb\u884c\u62e6\u622a\u81f3\u5173\u91cd\u8981\u3002.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u8fd0\u8425\u5546\u8fd8\u5e94\u8003\u8651\u53cc\u8fb9\u6f2b\u6e38\u534f\u8bae\u5bf9\u5408\u6cd5\u622a\u83b7\u7684\u5f71\u54cd\u3002\u6b64\u7c7b\u534f\u8bae\u901a\u5e38\u4fa7\u91cd\u4e8e\u5546\u4e1a\u6761\u6b3e\u3001\u670d\u52a1\u8d28\u91cf\u548c\u6d41\u91cf\u4ea4\u6362\u5b89\u6392\uff0c\u4f46\u5f88\u5c11\u6d89\u53ca\u5408\u6cd5\u622a\u83b7\u95ee\u9898\u3002 \u5728\u6f2b\u6e38\u534f\u8bae\u4e2d\u7eb3\u5165\u5408\u6cd5\u622a\u53d6\u6761\u6b3e\u2014\u2014\u6216\u8005\u81f3\u5c11\u5728\u76f8\u5173\u6280\u672f\u6587\u6863\u4e2d\u4e88\u4ee5\u8bf4\u660e\u2014\u2014\u6709\u52a9\u4e8e\u786e\u4fdd\u53cc\u65b9\u660e\u786e\u5404\u81ea\u5728\u622a\u53d6\u6f2b\u6e38\u6d41\u91cf\u65b9\u9762\u7684\u8d23\u4efb\u548c\u80fd\u529b\u3002\u968f\u77405G\u65f6\u4ee3\u65b0\u578b\u6f2b\u6e38\u6a21\u5f0f\u7684\u51fa\u73b0\uff0c\u6d41\u91cf\u8def\u7531\u548c\u7f51\u7edc\u529f\u80fd\u90e8\u7f72\u7684\u9009\u9879\u6bd4\u524d\u51e0\u4ee3\u7f51\u7edc\u66f4\u52a0\u591a\u6837\u5316\uff0c\u8fd9\u4e00\u70b9\u663e\u5f97\u5c24\u4e3a\u91cd\u8981\u3002.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u968f\u7740\u56fd\u9645\u6570\u636e\u6d41\u91cf\u7684\u589e\u52a0\uff0c\u6f2b\u6e38\u5408\u6cd5\u622a\u83b7\u7684\u60c5\u666f\u5c06\u53d8\u5f97\u66f4\u52a0\u590d\u6742\u3002\u8fd0\u8425\u5546\u5fc5\u987b\u786e\u4fdd\u5176\u6f2b\u6e38 <a href=\"https:\/\/ic-services.io\/zh\/%e8%a7%a3%e5%86%b3%e6%96%b9%e6%a1%88\/%e5%90%88%e6%b3%95%e6%8b%a6%e6%88%aa\/\">\u5408\u6cd5\u622a\u83b7\u80fd\u529b<\/a> \u7b26\u5408\u6240\u6709\u9002\u7528\u7684\u76d1\u7ba1\u8981\u6c42\u3002.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">\u76f8\u5173\u6587\u7ae0<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\u5982\u9700\u8fdb\u4e00\u6b65\u4e86\u89e3\u76f8\u5173\u4e3b\u9898\uff0c\u8bf7\u6d4f\u89c8\u8fd9\u4e9b\u6587\u7ae0\uff1a<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><a href=\"https:\/\/ic-services.io\/zh\/?p=2175\">MVNO \u4e0e MNO\uff1a\u8c01\u5bf9\u5408\u6cd5\u62e6\u622a\u8d1f\u6709\u6cd5\u5f8b\u8d23\u4efb\uff1f<\/a><\/li>\n<li><a href=\"https:\/\/ic-services.io\/zh\/?p=2142\">\u963f\u8054\u914b\u548c\u6d77\u6e7e\u56fd\u5bb6\u7684\u5408\u6cd5\u62e6\u622a\uff1a\u8fdb\u5165\u5e02\u573a\u7684\u6b27\u6d32\u8fd0\u8425\u5546\u987b\u77e5<\/a><\/li>\n<li><a href=\"https:\/\/ic-services.io\/zh\/?p=2173\">MVNO LI \u6e05\u5355\uff1a\u4e0a\u7ebf\u524d\u6240\u9700\u7684\u4e00\u5207<\/a><\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">\u5916\u90e8\u8d44\u6e90<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\u4ee5\u4e0b\u5916\u90e8\u8d44\u6e90\u63d0\u4f9b\u4e86\u66f4\u591a\u80cc\u666f\u8d44\u6599\u548c\u5b98\u65b9\u6587\u4ef6\uff1a<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><a href=\"https:\/\/www.gsma.com\" target=\"_blank\" rel=\"noopener noreferrer\">\u5168\u7403\u79fb\u52a8\u901a\u4fe1\u7cfb\u7edf\u534f\u4f1a\uff08GSMA\uff09<\/a><\/li>\n<li><a href=\"https:\/\/www.etsi.org\/technologies\/lawful-interception\" target=\"_blank\" rel=\"noopener noreferrer\">ETSI \u5408\u6cd5\u62e6\u622a\u6807\u51c6<\/a><\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>Roaming lawful interception scenarios create complex jurisdictional and technical challenges for operators.
