1、 AMERICAN NATIONAL STANDARD FOR TELECOMMUNICATIONS ATIS-0700724.2014 UMTS Handover Interface for Lawful Interception As a leading technology and solutions development organization, ATIS brings together the top global ICT companies to advance the industrys most-pressing business priorities. Through A
2、TIS committees and forums, nearly 200 companies address cloud services, device solutions, emergency services, M2M communications, cyber security, ehealth, network evolution, quality of service, billing support, operations, and more. These priorities follow a fast-track development lifecycle from des
3、ign and innovation through solutions that include standards, specifications, requirements, business use cases, software toolkits, and interoperability testing. ATIS is accredited by the American National Standards Institute (ANSI). ATIS is the North American Organizational Partner for the 3rd Genera
4、tion Partnership Project (3GPP), a founding Partner of oneM2M, a member and major U.S. contributor to the International Telecommunication Union (ITU) Radio and Telecommunications sectors, and a member of the Inter-American Telecommunication Commission (CITEL).

5、ATIONAL STANDARD Approval of an American National Standard requires review by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substan
6、tial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made towards their resolution. Th

Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standard

25、this may only be on a particular communication. It should be noted that when lawful interception is activated, it shall be invoked on all communications (Invocation takes place either subsequent to or simultaneously with activation.). Operation is the procedure which occurs once a service has been i
26、nvoked. NOTE: The definition is based on 8, but has been adapted for the special application of lawful interception, instead of supplementary services. 3.1.16 law enforcement agency: organization authorized by a lawful authorization based on a national law to request interception measures and to rec
27、eive the results of telecommunications interceptions. 3.1.17 law enforcement monitoring facility: law enforcement facility designated as the transmission destination for the results of interception relating to a particular interception subject. 3.1.18 lawful authorization: permission granted to a LE
28、A under certain conditions to intercept specified telecommunications and requiring co-operation from a network operator / access provider / service provider. Typically this refers to a warrant or order issued by a lawfully authorized body. 3.1.19 lawful interception: see interception. 3.1.20 lawful
29、interception identifier: identifier for a particular interception. 3.1.21 location information: information relating to the geographic, physical or logical location of an identity relating to an interception subject. 3.1.22 mediation device: equipment, which realizes the mediation function. 3.1.23 m
30、ediation function: mechanism which passes information between a network operator, an access provider or service provider and a handover interface, and information between the internal network interface and the handover interface. ATIS-0700724.2014 5 3.1.24 network element: component of the network s
31、tructure, such as a local exchange, higher order switch or service control processor. 3.1.25 network element identifier: uniquely identifies the relevant network element carrying out the lawful interception. 3.1.26 network identifier: internationally unique identifier that includes a unique identifi
32、cation of the network operator, access provider, or service provider and, optionally, the network element identifier. 3.1.27 network operator: operator of a public telecommunications infrastructure which permits the conveyance of signals between defined network termination points by wire, by microwa
33、ve, by optical means or by other electromagnetic means. 3.1.28 quality of service: quality specification of a telecommunications channel, system, virtual channel, computer-telecommunications session, etc. Quality of service may be measured, for example, in terms of signal-to-noise ratio, bit error r
34、ate, message throughput rate or call blocking probability. 3.1.29 reliability: probability that a system or service will perform in a satisfactory manner for a given period of time when used under specific operating conditions. 3.1.30 result of interception: information relating to a target service,
35、 including the content of communication and intercept related information, which is passed by a network operator, an access provider or a service provider to a law enforcement agency. Intercept related information shall be provided whether or not call activity is taking place. 3.1.31 service informa
36、tion: information used by the telecommunications infrastructure in the establishment and operation of a network related service or services. The information may be established by a network operator, an access provider, a service provider or a network user. 3.1.32 service provider: natural or legal p
37、erson providing one or more public telecommunications services whose provision consists wholly or partly in the transmission and routing of signals on a telecommunications network. A service provider needs not necessarily run his own network. 3.1.33 SMS: Short Message Service gives the ability to se
38、nd character messages to phones. SMS messages can be MO (mobile originate) or MT (mobile terminate). 3.1.34 target identity: technical identity (e.g., the interceptions subject directory number), which uniquely identifies a target of interception. One target may have one or several target identities
39、. 3.1.35 target service: telecommunications service associated with an interception subject and usually specified in a lawful authorization for interception. NOTE: There may be more than one target service associated with a single interception subject. 3.1.36 telecommunications: any transfer of sign
40、s, signals, writing images, sounds, data or intelligence of any nature transmitted in whole or in part by a wire, radio, electromagnetic, photoelectronic or photo-optical system. 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: AP Access Provider ASN.1 A

As a consequence, the present document shall define, in addition to mandatory requirements, which are always applicable, supplementary options, in order to take into account the various influences listed above. 4.3 Functiona
47、l Requirements A lawful authorization shall describe the kind of information IRI only, or IRI with CC that is required by an LEA, the identifiers for the interception subject, the start and stop time of LI, and the addresses of the LEAs for delivery of CC and/or IRI and further information. A single
48、 interception subject may be the subject of interception by different LEAs. It shall be possible strictly to separate these interception measures. If two targets are communicating with each other, each target is dealt with separately. ATIS-0700724.2014 8 4.4 Overview of Handover Interface The generi
49、c handover interface adopts a three port structure such that administrative information (HI1), intercept related information (HI2), and the content of communication (HI3) are logically separated. Figure 4.1 shows a block diagram with the relevant entities for Lawful Interception. The outer circle represents the NWO/AP/SvPs domain with respect to lawful interception. It contains the network internal functions, the internal network interface (INI), the administration function and the mediation functions for IRI and CC. The inner ci
