The LI IRI event information is sent to the DF2/DF3 is triggered by different PTC session related and non-call related events/reports. Details for each event are described in the following clauses.
Within Table 22.214.171.124: IRI Information Elements for PTC Event Records, a provisioned target identity can be a SIP URI, TEL URI , MCPTT ID or an IMEI.
A PTC Client may support multiple PTC Addresses and be involved in one or more PTC Sessions at the same time using the same or different PTC Addresses.
A set of elements as shown below can be associated with the events. The events trigger the transmission of the information from PTC ICE to DF2. Available IEs from this set of elements as shown below can be extended in the PTC ICE, if this is necessary as a national option. DF2 can extend available information if this is necessary as a national option e.g. a unique number for each surveillance warrant.
