Refer to actual network operation & maintenance, a subset of IRP requirements on Itf-N has been described in TR 32.861 based on existing TS 32-series specifications. In order to put it into practice, both functionalities and solution sets for the simplified Itf-N are urgently needed to be studied. This document is subsequent study to TR 32.861 (Study on Application and Partitioning of Itf-N), which also takes existing 32-series specifications into consideration. This document aims to provide one solution sets for requirements of Itf-N raised by TR 32.861.

The present document examines the IRP Information Service (IS) of Itf-N from existing TS 32-series specifications and identifies one subset of IRP functionality according to the IRP requirements in TR 32.861, also studies diverse solution sets and compares them between each other on efficiency and complexity. Finally, this document gives a suggestion of one or more solution set(s) for above identified IS subset.
