9 Interworking considerations
22.0673GPPenhanced Multi Level Precedence and Pre-emption service (eMLPP)Stage 1TS
Interworking of the eMLPP service with other networks shall be provided based on the MLPP service specified in ITU‑T Recommendation I.255.3 or a possibly future EN related to MLPP.
For this interworking it shall be considered that:
‑ precedence levels A and B shall be mapped to precedence level 0 (see clause 4);
‑ pre‑emption of network resources and on‑going calls in the interfacing network will be performed according to the MLPP service, i.e. pre‑emption will only affect other MLPP subscribers;
‑ other details in the treatment of precedence calls as specified for MLPP which are different to eMLPP.
The precedence level of a call except levels A and B shall not be changed when interworking with networks providing MLPP.
