TKG 2021 规定的奥地利合法拦截要求给电信运营商带来了独特的挑战。随着《2021 年电信法》（TKG 2021）的出台，奥地利的电信监管格局发生了重大转变，该法取代了之前的《2003 年电信法》，使该国的法律框架与《欧洲电子通信法》（EECC）更加一致。对于运营商（尤其是 MVNO 和新市场进入者）而言，了解 TKG 2021 对合法拦截的影响对于实现和保持奥地利市场的合规性至关重要。.
Austria splits the job in two. Real-time interception (IRI and CC) is handed over to the Federal Ministry of the Interior (BM.I) in the ETSI formats that the Überwachungsverordnung (ÜVO, BGBl. II Nr. 418/2001 as amended) prescribes. Requests for stored data (Auskünfte) and the answers to them run through the Durchlaufstelle (DLS), an encrypted mailbox system that the Bundesrechenzentrum (BRZ) operates under §§ 171–172 TKG 2021. This dual structure means that operators must satisfy both the legal requirements set out in the TKG 2021 and the Strafprozessordnung (StPO), and the technical specifications of the ÜVO for the delivery of intercepted communications. The DLS itself is governed by the TKG-Datensicherheitsverordnung (TKG-DSVO). Getting either side wrong can result in administrative fines and coercive measures.
奥地利根据《2021 年技术合作准则》进行的合法截取
The TKG 2021 establishes the general obligation for providers of public telecommunications services to cooperate with lawful interception requests. Section 162 of the TKG 2021 requires providers to supply all facilities needed for interception and data disclosure, and to cooperate with each order to the extent required. This obligation applies to all providers of public communications services, regardless of their size or business model — MVNOs are not exempt.
The procedural basis for ordering an interception is found in the StPO (Code of Criminal Procedure). Besides the StPO, providers must also cooperate with measures under the State Protection and Intelligence Act (SNG), the Fiscal Penal Code (FinStrG) and the Military Powers Act (MBG) (§ 162 TKG 2021). Under Austrian law, the interception is ordered by the public prosecutor’s office and requires prior authorisation by a court (§ 137 StPO). The StPO specifies the types of offences that can trigger an interception order, the maximum duration of surveillance, and the conditions under which extensions may be granted. Operators are legally bound to comply with valid interception orders and face penalties for refusal or undue delay.
One important distinction in Austrian law is between the interception of content data (Inhaltsdaten) and the collection of traffic data (Verkehrsdaten) and location data (Standortdaten). Each category has different legal thresholds and procedural requirements. Both measures generally require an intentional offence punishable by more than one year’s imprisonment (§ 135 StPO). Content interception also requires a close link between the intercepted device and the suspect.
Austria has had no general 数据保留 since the Constitutional Court struck it down in 2014. Since 2018 the StPO has allowed targeted preservation instead (Anlassdatenspeicherung, § 135 (2b) StPO): on an initial suspicion, the public prosecutor can order a provider to keep specific data for up to 12 months. Operators must understand how these provisions interact with their general LI obligations to avoid gaps in compliance.
The BM.I Handover and the BRZ Durchlaufstelle
The Bundesrechenzentrum (BRZ) is Austria’s federal computing centre. It does not receive intercepted communications: real-time IRI and CC are delivered by the operator to the Federal Ministry of the Interior (BM.I), the 执法 side of the handover. The BRZ sets up and runs the Durchlaufstelle (DLS), an electronic mailbox system for the secure handling of data-disclosure requests and their answers (§§ 171–172 TKG 2021). Operators that pay the RTR financing contribution under § 34 KOG must answer requests through it.
The handover format is set by the ÜVO: ETSI ES 201 671 for classic voice, and ETSI TS 102 232-1/-5 for VoLTE. Operators must ensure that their systems can deliver both intercept-related information (IRI) and content of communications (CC) in these formats. The Austrian options (TCP over a VPN across the public Internet, LIID and operator identifiers agreed with the BM.I) are documented in the industry recommendation AK-TK EP 023, which the RTR publishes.
Data-disclosure requests (Auskünfte) and their answers are exchanged through the DLS mailbox system, with authentication, integrity protection and revision-proof statistics (§ 171 TKG 2021). Interception orders themselves are issued by the public prosecutor’s office on the basis of a court authorisation and are carried out by the provider together with the BM.I.
For operators new to the Austrian market, agreeing the handover with the BM.I is one of the earliest steps in the compliance journey. Before going live, the operator agrees the handover parameters with the BM.I and runs test interceptions over the agreed VPN connection. The DLS connection for data requests is set up separately with the BRZ. Operators should factor in several months for this process, as scheduling, development, and testing cycles can be lengthy — particularly for MVNOs that need to coordinate with their host MNO’s infrastructure.
MVNO 的具体考虑因素
MVNOs operating in Austria face the same fundamental challenge as in other European markets: every provider must cooperate with interception orders, but the technical capability to intercept often resides with the host MNO. Every provider must cooperate with interception orders (§ 162 TKG 2021), and holding a notification with the Rundfunk und Telekom Regulierungs-GmbH (RTR) does not reduce that duty. The detailed technical facility duties of the ÜVO, however, are tied to the network in which the subscriber connections physically exist. Light MVNOs therefore need a written arrangement with their host network that covers how orders are executed and who builds the handover.
This means that MVNOs must either deploy their own LI infrastructure — including a 中介函数 capable of delivering to the BM.I — or establish a formal agreement with their host MNO under which the MNO performs interception on the MVNO’s behalf. In the latter case, the MVNO must still ensure that the arrangement meets the ÜVO requirements and that the MVNO retains visibility and control over the process. Simply delegating responsibility to the MNO without formal agreements and technical validation is a compliance risk that the Fernmeldebüro and the BM.I will not overlook.
The architectural model of the MVNO also matters. Full MVNOs that operate their own core network elements have more direct control over interception capabilities and can implement LI systems that deliver directly to the BM.I. Light MVNOs and resellers, which rely more heavily on the host MNO’s infrastructure, face greater dependency and must invest more heavily in contractual and procedural safeguards.
MVNO 尤为复杂的一个领域是 VoLTE 流量的处理。随着奥地利运营商将语音服务迁移到 LTE，并越来越多地迁移到 5G，语音通话的拦截已从电路交换基础设施转移到分组交换基础设施。依赖其主 MNO 提供 VoLTE 服务的 MVNO 必须确保其 LI 安排涵盖 VoLTE 通话的拦截，因为其技术机制与传统的电路交换拦截有很大不同。.
技术实施要求
The technical requirements for LI in Austria follow ETSI standards with the Austrian options of AK-TK EP 023. Operators must support the delivery of IRI (via HI2) and CC (via HI3) in the formats prescribed by the ÜVO. The IRI must include all required metadata, such as calling and called numbers, timestamps, cell identifiers, and IP addresses, depending on the type of communication being intercepted.
For voice interception, the CC must be delivered as a real-time audio stream. For data interception, the CC consists of the IP packets associated with the target’s sessions. For VoLTE and VoWiFi, AK-TK EP 023 specifies delivery to the BM.I over TCP across a VPN, with the destination ports assigned by the BM.I. For other services, such as Internet access, the ÜVO names no handover standard, so the format and transport have to be agreed with the BM.I.
运营商还必须具备强大的目标识别能力。奥地利截获指令可通过电话号码（MSISDN）、IMSI、IMEI、IP 地址或电子邮件地址识别目标。运营商的 LI 系统必须能够将这些标识符解析为活动会话或用户，并启动相应的拦截。对于 MVNO，这可能需要与主机 MNO 的用户管理系统集成，以准确识别和跟踪目标。.
Before an operator receives live interception orders, the handover is tested with the BM.I over the agreed VPN connection. The test interceptions typically cover voice call interception, SMS interception, data session interception, and target identification using various selectors, and should be repeated whenever the LI systems are upgraded or modified.
合规时限和执行
Breaches of the LI duties are administrative offences prosecuted by the Fernmeldebüro: up to EUR 50,000 for failing to cooperate with an order and up to EUR 100,000 for failing to provide the required interception facilities (§ 188 TKG 2021). The RTR handles notifications and market regulation, not LI enforcement. On application by the public prosecutor, the court can also impose coercive penalties (Beugemittel) to enforce cooperation (§ 93 (2) and (4) StPO).
The ÜVO obligations apply from the day the service launches, so operators entering the Austrian market should plan the six to twelve months of LI build and testing with the BM.I before commercial launch. This timeline accounts for technical development, integration testing, test interceptions with the BM.I, and internal process development. MVNOs with more complex supply chains may need longer, particularly if their host MNO agreements need to be renegotiated to include LI provisions.
奥地利的执法环境在不断变化。随着新的 MVNO、物联网运营商和 OTT 提供商进入市场，电信市场变得更加分散，监管机构对信息通信技术合规性的关注可能会增加。尽早建立健全合规框架的运营商将能更好地适应未来的监管变化，避免执法行动。.
实用建议
For operators preparing for 合法截取合规性 in Austria, several practical steps are recommended. Begin by thoroughly reviewing the TKG 2021 and the relevant sections of the StPO to understand your legal obligations. Engage legal counsel with specific Austrian telecommunications expertise, as the interaction between criminal procedure law and telecommunications regulation requires specialist knowledge.
Contact the BM.I early in your planning process to agree the handover parameters, and set up the DLS connection with the BRZ. Develop your technical infrastructure — whether in-house or through a managed service provider — to meet the ÜVO and AK-TK EP 023 requirements. Ensure that your LI管理系统 supports the full lifecycle of interception orders, from receipt and activation through monitoring and deactivation.
如果您是 MVNO，请审查并在必要时重新谈判您的主机 MNO 协议，以明确解决 LI 责任问题。为拦截请求建立明确的升级路径和响应时间承诺。最后，制定并记录处理拦截指令的内部流程，包括访问控制、保密程序和审计跟踪。.
结论
Austria’s lawful interception framework, anchored by the TKG 2021 and the ÜVO, with real-time handover to the BM.I and data requests through the BRZ Durchlaufstelle, represents a well-structured but demanding compliance environment. For MVNOs and new market entrants, the combination of legal obligations and technical requirements means that early planning, proactive engagement with the BM.I and the BRZ, and investment in robust LI infrastructure are essential. The consequences of non-compliance — administrative fines, coercive measures, and reputational damage — far outweigh the costs of getting it right from the start. By understanding the Austrian LI landscape and taking a systematic approach to compliance, operators can build a solid foundation for long-term success in this important European market.
The lawful interception Austria compliance landscape continues to evolve as the ÜVO and the industry recommendations are updated. Operators must ensure their lawful interception Austria implementations remain aligned with current specifications.
