Lawful Interception (LI) - Dictionary for common parameters

The present document defines a dictionary of parameters that are commonly used in multiple TC LI specifications. Aside from defining a dictionary, the present document aims to provide technical means for other specifications to use. It is encouraged to use the present document in the development of new specifications. It is foreseen that regular maintenance of the present document is required. As such, release management requirements will be defined. Before accepting any new common parameter, the present document will provide a set of requirements the parameter has to comply to in order to become a common parameter.

Zakonito prestrezanje (LI) - Slovar skupnih parametrov

V tem dokumentu je opredeljen slovar parametrov, ki se običajno uporabljajo v specifikacijah TC LI. Poleg opredelitve slovarja je namen tega dokumenta zagotoviti tehnična sredstva za uporabo drugih specifikacij. Zaželeno je, da se ta dokument uporablja pri pripravi novih specifikacij. Predvideno je redno vzdrževanje dokumenta. V tem primeru je treba določiti zahteve za upravljanje objave. Pred sprejetjem novih skupnih parametrov je treba v tem dokumentu določiti zahteve, ki jih mora parameter izpolnjevati, da postane skupni parameter.

5 Parameter requirements
5.0 Introduction
This clause describes the requirements a parameter should comply to in order to be specified as a common parameter.
5.1 Parameter attributes
Name
• The parameter should be assigned a unique name. The naming conventions used are described in clause 5.2.
Description
• A description of the parameter should be provided.
Usage guidance
• If there are circumstances in which additional usage guidance is applicable, use cases may be described in this
attribute.
References to other specifications
• If the parameter is specified in another specification (such as an RFC), a reference to that specification shall be
provided. If possible, the reference should point to the exact clause in the specification.
EXAMPLE: Specify one or more sample values of the parameter.
Technical means to define and validate the parameter
• If possible, provide a regular expression to specify the value that is accepted by this parameter.
Implementations may be required to perform additional validation on the value. The regular expression is
defined per clause 5.4. Define the parameter in the XSD [2] in clause 7.1. When converting a regular
expression to an XSD [2] pattern, escape any XML [29] markup characters in the regular expression per
XML [29], section 2.4 to create a valid XSD [2] pattern.
• Define the parameter in the ASN.1 [3] in clause 7.2.
• Define the parameter in the JSON Schema [35] in clause 7.3. Unless otherwise specified, the JSON definition
shall be a translation of the XSD definition, following the translation given in annex C.
5.2 Parameter naming conventions
Allowed characters
• The following character classes are allowed: A-Z, a-z and 0-9.
Camel casing
• The name of the parameter is to be CamelCased, where the first character is uppercased. Any acronyms should
be uppercased.
EXAMPLE:
- IPv4Address.
- SIPURI.
- EmailAddress.
ETSI
12 ETSI TS 103 280 V2.16.1 (2025-08)
5.3 Technology conventions
The used technologies defined in clause 7 may impose requirements that conflict with the requirements in clauses 5.1
and 5.2. In the case of a conflict and in exceptional cases, it is allowed to deviate from the requirements above.
5.4 Regular expression conventions
Regular expressions used for validation shall be limited to the regular expression capabilities supported by both
XSD [2] patterns and ECMAScript regular expressions (see ECMA-262 [36], section 22.2.1, as used by JSON
Schema [35] patterns).
Given the high disparity of regular expression implementations, the regular expressions should be limited to the
following features (inspired by JSON Schema [35], section 6.4):
1) Individual Unicode characters. Unicode characters for XSD [2] need to be encoded using an appropriate
XML [29] entity.
2) Character classes: "[abc]" (simple character classes), and "[a-z]" (range character classes).
3) Negated character classes: "[^abc]" (negated simple character classes), and "[^a-z]" (negated range
character classes).
4) Simple quantifiers: "*" (zero or more occurrences), "+" (one or more occurrence), and "?" (zero or one
occurrence).
5) Range quantifiers: "{n}" (exactly n occurrences), "{n,m}" (between n and m occurrences), and "{n,}" (at
least n occurrences).
6) Grouping and alternation: "(" and ")" (simple grouping), and "|" (alternation).
7) Simple atoms: "." (any character except new line and line feed).
As XSD [2] patterns are matched to the entire value, regular expressions shall not start with the anchor "^" or end with
the anchor "$". When regular expressions are mapped to a JSON Schema [35] pattern per table C.2, the anchors are
required.

6 Parameter dictionary
6.1 LIID
Name LIID
Description
For each target identity related to an interception measure, the authorized CSP operator shall
assign a special Lawful Interception IDentifier (LIID), which has been agreed between the LEA
and the CSP. It is used within parameters of all HI interface ports.

Using an indirect identification, pointing to a target identity makes it easier to keep the
knowledge about a specific interception target limited within the authorized CSP operators and
the handling agents at the LEA.

The Lawful Interception IDentifier LIID is a component of the CC delivery procedure and of the
IRI records. It shall be used within any information exchanged at the Handover Interfaces HI2
and HI3 for identification and correlation purposes.

The LIID format shall consist of alphanumeric characters. It might for example, among other
information, contain a lawful authorization reference number, and the date, when the lawful
authorization was issued.
The authorized CSP shall either enter a unique LIID for each target identity of the interception
subject or as a national option a single LIID for multiple target identities all pertaining to the
same interception subject.
EXAMPLE: The interception subject has a telephony service with three telephone numbers.
The CSP enters for each telephone number an own LIID, or optionally enters one
LIID for all three telephone numbers.

If more than one LEA intercepts the same target identity, there shall be unique LIIDs assigned,
relating to each LEA.
Usage guidance The LIID is defined as an OCTET STRING in ASN.1. This means it is possible to use binary
octets or ASCII printable characters to express the LIID. To correctly handle this, the parameter
accepts both variations.

4 Release management
This clause describes the release management requirements. The requirements are:
• The version of the present document is defined as ...
• The major version should be incremented when making a backwards incompatible change.
• The minor version should be incremented when adding backwards compatible functionality.
• The patch version should be incremented when fixing a backwards compatible bug.
• Once a major version has been incremented, the previous major version will be supported for 2 years after
publication of the new version. Change requests issued to a version that is no longer supported will need to be
issued for the latest supported major version.

5 Parameter requirements
5.0 Introduction
This clause describes the requirements a parameter should comply to in order to be specified as a common parameter.
5.1 Parameter attributes
Name
• The parameter should be assigned a unique name. The naming conventions used are described in clause 5.2.
Description
• A description of the parameter should be provided.
Usage guidance
• If there are circumstances in which additional usage guidance is applicable, use cases may be described in this
attribute.
References to other specifications
• If the parameter is specified in another specification (such as an RFC), a reference to that specification shall be
provided. If possible, the reference should point to the exact clause in the specification.
EXAMPLE: Specify one or more sample values of the parameter.
Technical means to define and validate the parameter
• If possible, provide a regular expression to specify the value that is accepted by this parameter.
Implementations may be required to perform additional validation on the value. The regular expression is
defined per clause 5.4. Define the parameter in the XSD [2] in clause 7.1. When converting a regular
expression to an XSD [2] pattern, escape any XML [29] markup characters in the regular expression per
XML [29], section 2.4 to create a valid XSD [2] pattern.
• Define the parameter in the ASN.1 [3] in clause 7.2.
• Define the parameter in the JSON Schema [35] in clause 7.3. Unless otherwise specified, the JSON definition
shall be a translation of the XSD definition, following the translation given in annex C.
5.2 Parameter naming conventions
Allowed characters
• The following character classes are allowed: A-Z, a-z and 0-9.
Camel casing
• The name of the parameter is to be CamelCased, where the first character is uppercased. Any acronyms should
be uppercased.
EXAMPLE:
- IPv4Address.
- SIPURI.
- EmailAddress.
ETSI
12 ETSI TS 103 280 V2.16.1 (2025-08)
5.3 Technology conventions
The used technologies defined in clause 7 may impose requirements that conflict with the requirements in clauses 5.1
and 5.2. In the case of a conflict and in exceptional cases, it is allowed to deviate from the requirements above.
5.4 Regular expression conventions
Regular expressions used for validation shall be limited to the regular expression capabilities supported by both
XSD [2] patterns and ECMAScript regular expressions (see ECMA-262 [36], section 22.2.1, as used by JSON
Schema [35] patterns).
Given the high disparity of regular expression implementations, the regular expressions should be limited to the
following features (inspired by JSON Schema [35], section 6.4):
1) Individual Unicode characters. Unicode characters for XSD [2] need to be encoded using an appropriate
XML [29] entity.
2) Character classes: "[abc]" (simple character classes), and "[a-z]" (range character classes).
3) Negated character classes: "[^abc]" (negated simple character classes), and "[^a-z]" (negated range
character classes).

occurrence).

6 Parameter dictionary
6.1 LIID
Name LIID
Description
For each target identity related to an interception measure, the authorized CSP operator shall
assign a special Lawful Interception IDentifier (LIID), which has been agreed between the LEA
and the CSP. It is used within parameters of all HI interface ports.

Using an indirect identification, pointing to a target identity makes it easier to keep the
knowledge about a specific interception target limited within the authorized CSP operators and
the handling agents at the LEA.

The Lawful Interception IDentifier LIID is a component of the CC delivery procedure and of the
IRI records. It shall be used within any information exchanged at the Handover Interfaces HI2
and HI3 for identification and correlation purposes.

The LIID format shall consist of alphanumeric characters. It might for example, among other
information, contain a lawful authorization reference number, and the date, when the lawful
authorization was issued.
The authorized CSP shall either enter a unique LIID for each target identity of the interception
subject or as a national option a single LIID for multiple target identities all pertaining to the
same interception subject.
EXAMPLE: The interception subject has a telephony service with three telephone numbers.
The CSP enters for each telephone number an own LIID, or optionally enters one
LIID for all three telephone numbers.

If more than one LEA intercepts the same target identity, there shall be unique LIIDs assigned,
relating to each LEA.
Usage guidance The LIID is defined as an OCTET STRING in ASN.1. This means it is possible to use binary
octets or ASCII printable characters to express the LIID. To correctly handle this, the parameter
accepts both variations.
