The information pertaining to these essential IPRs, i

Latest updates are availab
22、le on the ETSI Web server (https:/ipr.etsi.org/). Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web server) which are,
23、or may be, or may become, essential to the present document. Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Lawful Interception (LI). The present document is part 2 of a multi-part deliverable. Full details of the entire series can be found in part 1 3. The
24、ASN.1 module is also available as an electronic attachment to the original document from the ETSI site (see details in annex D). Modal verbs terminology In the present document “shall“, “shall not“, “should“, “should not“, “may“, “need not“, “will“, “will not“, “can“ and “cannot“ are to be interpret
25、ed as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of provisions). “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. Introduction The present document describes what information is required for the handover of inter
26、cepted IP-based messaging traffic from a Communications Service Provider to an LEMF. The present document covers a stage 2 description of the data, but does not specify any functionality within the scope of ETSI TS 102 232-1 3. The Recommendation ITU-T I.130 6 method for characterizing a service wil
27、l be used as a general framework for the present document. The modified concept of a “stage 1“ will be called the “attributes“ of the interface. The attributes of the interface are the sum total of the entire constituent attributes that an interface may need to communicate. The modified concept of a
28、 “stage 2“ will be called the “events“ of the interface. The events of the interface define the rules of the relationships between the attributes that are required to arrange the disjoint attributes into meaningful information for a messaging service interaction. The present document is intended to
29、be general enough to be used in a variety of messaging services. It should be recognized that a side effect of this approach is some IRI fields identified may be difficult to extract or non-existent depending on the messaging service being intercepted. In such cases it may be completely reasonable t
30、hat the delivered IRI contain empty fields or fields with the value 0. ETSI ETSI TS 102 232-2 V3.9.1 (2016-03)7 1 Scope The present document contains a stage 1 like description of the interception information in relation to the process of sending and receiving asynchronous messages. The present docu
31、ment also contains a stage 2 like description of when Intercept Related Information (IRI) and Content of Communication (CC) need to be sent, and what information it needs to contain. It is recognized that “Instant Messenger“ and “Chat“ applications are another way of exchanging electronic text messa
32、ges. While the present document may be applicable to such applications it is in no way a goal of the present document to address these methods of electronic text messaging. The definition of handover transport and encoding of HI2 and HI3 is outside the scope of the present document. Refer to ETSI TS
33、 102 232-1 3. The present document is designed to be used where appropriate in conjunction with other deliverables that define the service specific IRI data formats. The present document aligns with 3GPP TS 33.108 5, ETSI TS 101 671 4, ETSI TS 101 331 1 and ETSI TR 101 944 i.1. 2 References 2.1 Norm
