5.1.2	General principles

...<pre>For interception, there needs to be a means of identifying the target, correspondent and initiator and related parties of any targeted communication. A means shall exist for the operator to intercept communications based on long term or permanent identifiers associated with a target service or equipment, as identified by the LEA. To achieve interception, the operator may need to translate these into further associated identifiers, in order to identify the data to be intercepted. Target identities used for interception for each domain and service are target service and equipment associated with target use or any derived IDs from such elements that are to be defined in TS 33.107 [9] and TS 33.108 [10]. Examples of these identities are IMSI, MSISDN, NAI, Tel URI, SIP URI, for the target service and IMEI, MAC for the equipment.</pre>
...<pre>National regulations may require that an operator is able to intercept any communication passing through its network based on any visible identity not connected to the operator network. It shall be based on a match between this target identity and identity type (e.g. IMPU) with the detected party fields. This identity is referred as a Non-Local Identity.</pre>
