Technical requirements for the handover interfaces for the execution of telecommunications surveillance

For the NEID conveyed within the IRI-Records, ETSI TS 101 671 V3.12.1 Annex D.5 IRI-Parameter Network-Element-Identifier applies.

Note that ETSI TS 102 232-1 V3.11.1 and ETSI TS 133 108 V13.4.0 import this parameter from ETSI TS 101 671 V3.12.1.

6.3.3 Communication Identity Number (CIN)

The Communication Identity Number (CIN) parameter is used in several handover interfaces and defined in ETSI TS 101 671 V3.12.1 §6.2.2 and ETSI TS 102 232-1 V3.11.1 §5.2.4.

The CIN parameter is assigned by the CSP.

a. For the CIN in the Called Party Number in the circuit switched handover interfaces using

ETSI TS 101 671 V3.12.1 or ETSI TS 133 108 V13.4.0:

The CIN delivered to the LEMF in the Called Party Subaddress when a CC-link is being established shall meet the requirements specified in ETSI TS 101 671 V3.12.1 Annex E,

Table E.3.4, or ETSI TS 133 108 V13.4.0 Annex J, Table J.2.5. The minimum required number of digits is 5 and the maximum is 8 digits.

b. For the CIN in the IRI-Records according to ETSI TS 101 671 V3.12.1 or ETSI TS 133

108 V13.4.0:

For the format of the CIN conveyed as IRI Parameter communication-Identity-

Number, ETSI TS 101 671 V3.12.1 Annex D.5 or ETSI TS 133 108 V13.4.0 Annex B.3a apply, with the CIN being encoded as ASCII with a range of 5 up to 8 digits.

c. For the CIN in the IRI-Records according to ETSI TS 102 232-1 V3.11.1:

For the format of the CIN conveyed as IRI Parameter communicationIdentityNumber, ETSI TS 102 232-1 V3.11.1 Annex A.2 applies, with the CIN being encoded as integer with a range of 0 up to 4294967295.

6.3.4 CCLID

The CCLID shall not be used, as for multiparty calls option A has to be implemented (ETSI TS 101 671 V3.12.1 Annex A.1.1 and A.5.4.2 or ETSI TS 133 108 V13.4.0 §5.1.3).

6.3.5 Correlation numbers and Correlation values

The Correlation Number and Correlation Values are specified in ETSI TS 133 108 V13.4.0 for packet switched based services and used to correlate CC and IRI or different IRI records within one PDP context or Bearer or Tunnel or VoIP session or conference session or group communication or MBMS session.

The Correlation Numbers and Correlation Values parameters are assigned by the CSP.
