4  Requirements  p. 6

4.1  General requirements  p. 6

The following general and high-level requirement applies for the present IRP:
The NRM defined by this IRP:
  • Shall support communications for telecommunication network management purposes, including management of converged networks.
  • Is a member of the Federated Network Information Model (FNIM) [7] and its information is derived from FNIM Umbrella Information Model (UIM) [8]

4.2  Requirements for management of E-UTRAN  p. 6

In addition to subclause 4.1, the following more specific requirements apply to E-UTRAN NRM:
REQ-EUTRAN_NRM-CON-001:
The NRM defined by this IRP shall contain E-UTRAN specific IOCs and related definitions, supporting E-UTRAN network entities.
REQ-EUTRAN_NRM-CON-002:
The NRM defined by this IRP shall support management of inter-system handover between EPS and UMTS, between EPS and GSM, and between EPS and CDMA2000.
REQ-EUTRAN_NRM-CON-003:
The NRM defined by this IRP shall support management of Inter-Radio Access Technology Automatic Neighbour Relation (IRAT ANR) from E-UTRAN to UTRAN, from E-UTRAN to GERAN, and from E-UTRAN to CDMA2000.
REQ-EUTRAN_NRM-CON-004:
The NRM defined by this IRP shall support management of Intra-E-UTRAN handover.
REQ-EUTRAN_NRM-CON-005:
The NRM defined by this IRP shall support management of Intra-E-UTRAN Automatic Neighbour Relation (ANR).
REQ-EUTRAN_NRM-CON-006:
The NRM defined by this IRP shall support management of E-UTRAN relaying by having a Relay Node (RN) wirelessly connect to a Donor eNB (DeNB).
REQ-EUTRAN_NRM-CON-007:
The NRM defined by this IRP shall support the management of designation of individual cells as reserved for special use, i.e. such that only UEs with an operator-specified subset of Access Classes 10 to 15 can use those cells.
REQ-EUTRAN_NRM-CON-008:
The NRM defined by this IRP shall support the management of shared E-UTRAN.
REQ-EUTRAN_NRM-CON-009:
The NRM defined by this IRP shall support the management of NB-IoT.
REQ-EUTRAN_NRM-CON-010:
The NRM defined by this IRP shall support the management of Master eNB in EN-DC (see TS 37.340).

4.3  Requirements for management of ng-eNB  p. 7

As ng-eNB is one RAN node type of NG-RAN [x], so the NG-RAN NRM requirements defined in TS 28.540 apply to ng-eNB NRM. In addition, the ng-eNB related MD-DC management requirements defined in TS 28.540 apply to ng-eNB NRM also, including management of ng-eNB in NGEN-DC or NE-DC operation.
