35、ause 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. T

36、he 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 iss

37、ued 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 conventio

38、ns 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 specifi

39、ed 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 or clause in the specification. EXAMPLE: Specify one or more sample values of the parameter. Technical means to define and validate the param

40、eter 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 expressions follow the IEEE POSIX 19, section 9 regular expression format but shall be limited to the reg

41、ular expression capabilities supported by XSD 2. ETSI ETSI TS 103 280 V2.1.1 (2017-08)8 Define the parameter in the XSD 2 in section 7.1. Define the parameter in the ASN.1 3 in section 7.2. 5.2 Parameter naming conventions Allowed characters The following characters are allowed: A-Z, a-z and 0-9. Ca

42、mel 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. 5.3 Technology conventions The used technologies defined in clause 7 may impose requirements that conflict with the

43、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. 6 Parameter dictionary LIID Name LIID Description For each target identity related to an interception measure, the authorized CSP operator shall assign a spe

44、cial 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 wi

45、thin 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 correlatio

46、n 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 o

47、f 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

48、 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 ch

49、aracters to express the LIID. To correctly handle this, the parameter accepts both variations. ETSI ETSI TS 103 280 V2.1.1 (2017-08)9 References ETSI TS 102 232-1 1, clause 5.2.2.
