35、se 4 Concepts and background For E-UTRAN, the ANR function in the eNB relates to the Use Cases Establishment of new eNB in network and Optimisation of the neighbourhood list in 4. - For Establishment of new eNB in network. If the operator so chooses, the OAM system adds and configures NCRs before th

36、e eNB goes into operation. - For Optimisation of the neighbourhood list, the ANR function deals with automatic NCR additions and removals. It minimizes the need for planning and configuring NCRs. If the operator so chooses, the OAM system adds and configures NCRs or removes NCRs after the eNB goes i

37、nto operation. For UTRAN, the ANR function concept and overall description is documented in TS 25.484 8. - The ANR function in RNC allows OAM system to manage the NCRT. OAM system can add and delete NCRs and also change the attributes of the NCRs. The OAM system is informed about changes in the NCRT

38、 made by ANR function. 5 Requirements 5.1 Business level requirements REQ-ANR-CON-001 NCRs shall be set up and optimized with no or minimal human intervention. REQ-ANR-CON-002 For E-UTRAN, initial status of the newly created NCR by ANR function shall be such that HO is allowed, X2 connection setup i

39、s allowed, and the NCR is allowed to be removed by ANR function in eNB. REQ-ANR-CON-003 E-UTRAN ANR supports management of NCRs from E-UTRAN to E-UTRAN, from E-UTRAN to UTRAN, from E-UTRAN to CDMA2000 and from E-UTRAN to GERAN. REQ-ANR-CON-004 For UTRAN, initial status of the newly created NCR by AN

40、R function shall be such that HO is allowed and the NCR is allowed to be removed by ANR function in RNC. REQ-ANR-CON-005 UTRAN ANR supports management of NCRs from UTRAN to UTRAN, from UTRAN to E-UTRAN and from UTRAN to GERAN. ETSI ETSI TS 132 511 V14.1.0 (2018-01)73GPP TS 32.511 version 14.1.0 Rele

Begins when This Use Case begins when all pre conditions have been met. Step 1 (*) (M) - If the IRPManager finds out that an unsuitable Neighbour Cell Relation has been adde

44、d by ANR, the IRPManager may “Blacklist” that particular Neighbour Cell Relation. - If the IRPManager finds out that a desired Neighbour Cell Relation has not been added by ANR, the IRPManager may “Whitelist” that particular Neighbour Cell Relation. - The IRPManager may uncheck the noRemove attribut

45、e from any present Neighbour Cell Relation. Ends when (*) This Use Case ends when the eNB or RNC is taken out of service or when the ANR function is stopped.
