ATIS-1000022 ii FOREWORD The Alliance for Telecommunication Industry Solutions (ATIS) serves the public through improved understanding between carriers, customers, and manufacturers. The Packet Technologies and Systems Committee (PTSC) - formerly T1S1 - develops a

9、nd recommends standards and technical reports related to services, architectures, and signaling, in addition to related subjects under consideration in other North American and international standards bodies. PTSC coordinates and develops standards and technical reports relevant to telecommunication

10、s networks in the U.S., reviews and prepares contributions on such matters for submission to U.S. ITU-T and U.S. ITU-R Study Groups or other standards organizations, and reviews for acceptability or per contra the positions of other countries in related standards development and takes or recommends

11、appropriate actions. Suggestions for improvement of this document are welcome. They should be sent to the Alliance for Telecommunications Industry Solutions, PTSC Secretariat, 1200 G Street NW, Suite 500, Washington, DC 20005. At the time it approved this document, PTSC, which is responsible for the

12、 development of this Technical Report, had the following members: B. Hall, PTSC Chair J. Zebarth, PTSC Vice-Chair C. Underkoffler, ATIS Chief Editor R.

13、 Associated Communications Identifying Information (CACmII) - see 6.1.2. CmII is “reasonably available” to an IASP if it is present at an intercept access point and can be made available without the provider being unduly burdened with network modifications. CmII is delivered by the set of messages d

14、efined in ATIS-1000013.2007 and the set of mandatory and conditional parameters contained therein. 6.1.1 Access Associated CmII (AACmII) Access Associated Communications Identifying Information (AACmII) is information associated with communication between the subscriber and the IAS network for the p

15、urposes of login, logout, access authorization, access authentication, or resource allocation caused by the use of, or attempted use of, the IAS network by the subscriber. 6.1.2 Content Associated CmII (CACmII) Content Associated Communications Identifying Information (CACmII) is information associa

16、ted with the delivery and routing of the subscriber packets in the network (e.g., the headers of the IP packets). 6.2 Communication Content (CmC) Communication Content (CmC) is the full IP packet stream to and from the subject. 7 LAES SIGNALING AND CONTENT AVAILABILITY AND CORRELATION 7.1 Availabili

17、ty The availability of signaling information (CII or CmII) and content (CC or CmC) for a specific court order depends upon the specific service provider scenario. The tables in Clause 8 provide details as to when the signaling information and content are available for delivery to an LEA. 7.2 Correla

18、tion LAES data correlation refers to the linking of signaling messages with content messages. It is the responsibility of the SP to provide signaling messages and content messages to Law Enforcement with ATIS-1000022 the proper identifying header information on all messages delivered to Law Enforcem

19、ent. Where a single SP delivers both the signaling messages and content messages, the SP populates correlation parameters to allow Law Enforcement to determine the association between the signaling and content. It is Law Enforcements responsibility to associate the appropriate signaling and content

20、messages with a given Lawful Intercept activity. Due to the distributed nature of IP based services (e.g., access, ISP, and VoP may be provided by three separate service providers), there are cases in which the service providers are not aware of any correlation between signaling and content and the

21、messages delivered to an LEA will not contain correlation parameters. Correlation across separate networks is the responsibility of the LEA. For example, in situations where signaling messages are delivered to the LEA by the VoP service provider (e.g., a Pen Register order served on a VoP TN) and co

22、ntent is delivered to the LEA by the IP network access provider (e.g., a Title III order served on a broadband access line), it is the LEAs responsibility to perform the task of data correlation. 8 APPLICABILITY OF WIRELINE VOP AND IAS LAES STANDARDS This clause addresses the use of LAES standards t

23、o provide surveillance information to an LEA in common SP scenarios. Figure 3 provides a high level depiction of the SP functionality involved in providing Internet Access and VoP and the LAES support that they provide. Any or all of the service providers may be requested, through a lawfully authori

24、zed electronic surveillance court order, to deliver various types of surveillance information to an LEA collection site. The particular messages to be generated and their source will depend on the SP scenario, the type of court order served (e.g., pen register, trap and trace, Title III) and the fac

25、ility or subject upon which the court order is served (e.g., a DSL line2, a user name, a VoP TN or URI). Figure 3 - SP Scenarios 2Identification of the DSL line varies by network implementation (e.g., MAC address, ATM VPI/VCI, telephone number, subscription identity). 7 ATIS-1000022 8 The following

26、sections address various service provider scenarios and indicate, for a type of court order and type of subject, what LAES information needs to be delivered, and what standards document applies. 8.1 Service Provider Scenario 1 In this scenario, all three services (Access, ISP, and VoP) are provided
