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

6.3.2 Communication Identifier (CID)

The communication identifier (CID) is used in several handover interfaces and defined in ETSI TS 101 671 V3.12.1 §6.2 and ETSI TS 102 232-1 V3.11.1 §5.2.4 and ETSI TS 133 108 V13.4.0 §5.1.2.

6.3.2.1 Operator Identity (OperatorID)

The OperatorID in Switzerland has a format of 5 digits.

It is issued by the PTSS and provided to the CSP with the following format:

N N N N N

Requirements specified by ETSI shall be met as follows:

a. For insertion of the OperatorID in the Subaddress field, ETSI TS 101 671 V3.12.1 Annex

E and ETSI TS 133 108 V13.4.0 Annex J apply.

b. For the OperatorID contained within the IRI-Records, ETSI TS 101 671 V3.12.1 Annex

D.5 and ETSI TS 102 232-1 V3.11.1 Annex A.2 and ETSI TS 133 108 V13.4.0 Annex B the IRI-Parameter operator-Identifier applies.

6.3.2.2 Network Element ID (NEID)

The network element identifier distinguishes between the various source IIF carrying out the LI operations and thus potentially serving the LEMF. Depending on the handover interface in use the NEID may have different formats (e.g. e164-Format, iP-Address).

Requirements specified by ETSI shall be met as follows:

a. For the NEID conveyed in the Calling Party Number in the circuit switched handover

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

For the NEID delivered to LEMF within the Calling Party Number information element, the encoding of the NEID according to ETSI TS 101 671 V3.12.1 Annex E.4.2 or ETSI TS 133 108 V13.4.0 Annex J.2.4.2 apply, with the following clarification: The CSP shall make

provision that at the Handover Interface the Calling Party Number is delivered to the LEMF in one of the formats specified below, the choice (on a call-by-call basis) being a CSP option:

i. national number with Type of Number “unknown” with prefix (in Switzerland the prefix is “0”)

ii. national number with Type of Number “national number”

iii. international number with Type of Number “unknown” with prefix (in Switzerland the prefix is “00”)

iv. international number with Type of Number “international number”

v. Numbering Plan Identification shall be “ISDN/telephony numbering plan”

b. For the NEID in the IRI-Records:
